Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an information outlet serving as a wiring device for indoor information wiring.

[0002]

2. Description of the Related Art Conventionally, when constructing a LAN (local area network) system using Ethernet,
A twisted pair cable in which a twisted pair wire of 8 cores is housed in a sheath is widely used. Twisted pair cables have the advantage of being easy to wire because they are relatively inexpensive and flexible. Modular jacks are often used to connect twisted pair cables to each other or to other devices. Therefore, it has been proposed that an information outlet equipped with a modular jack be laid in advance in a suitable place indoors and the information terminal device be detachably connected to the information outlet at a desired location.

On the other hand, as a modular jack, a pressure contact terminal is provided as a terminal for connecting an electric wire such as a twisted pair cable, and an electric wire having an insulation coating is press-fitted into a pressure contact slit provided on the terminal, so that both edges of the pressure contact slit are connected. It is known that the core wire can be sandwiched by cutting the insulating coating. In this type of modular jack, in order to connect the electric wires to the plurality of terminals, a lever having a function of aligning the plurality of electric wires and holding the electric wires and press-fitting them into the terminals is pivotally mounted. In other words, the lever can be raised and lowered between the position where it covers the terminal and the position where it opens the terminal, and at the position where the terminal is opened, the wires are inserted and aligned with the lever, and then the lever is tilted to place the lever on the terminal. When covered, the wire is press-fitted into the terminal. By providing such a lever, a plurality of electric wires can be easily and simultaneously connected to the modular jack, which facilitates the connection work.

By the way, in order to attach this type of modular jack to a wall surface, a side surface of a fixture, or a construction surface such as a floor or an underfloor, as shown in FIGS. 20 and 21, a back surface is brought into contact with the construction surface. It is considered that the modular jack 6 is housed in the housing 60 that is attached by the method described in JP-A-10-208828. The housing 60 is composed of a body 61 that is fixed to the construction surface and holds the modular jack 6, and a cover 62 that is covered by the body 61. The peripheral wall of the body 61 has a plug insertion port 11 provided in the modular jack 6. The plug introduction port 63 is formed at the corresponding portion.

[0005]

By the way, in the above-mentioned configuration example, since the plug insertion opening 11 is open to the outside, the dust entering the plug insertion opening 11 is arranged inside the plug insertion opening 11. It is easy to attach to the contact. When the dust adheres to the contact in this way, the contact resistance with the modular plug 7 increases, or the contact absorbs moisture to rust the contact. If the contact resistance increases or the contact rusts, a signal loss occurs at the electrical connection portion between the modular jack and the modular plug, and the reliability of information transmission decreases.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an information outlet in which dust is prevented from adhering to contacts and contact reliability between a modular jack and a modular plug is improved. Especially.

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) As shown in FIG. 1 and FIG.
Although the modular jack 6 has a configuration similar to that of the conventional configuration shown in FIG. 2, a modular jack 6 having a different shape from the conventional configuration is used, and the housing 60 has a door 7 for opening and closing the plug insertion port 11.
0 is set.

The housing 60 is composed of a body 61 attached to the construction surface with the back surface abutting the construction surface, and a cover 62 attached to the body 61. Columnar portions 64 are erected at four locations on the inner bottom surface of the body 61.
Assembling holes 64a are formed on the outer side surfaces of each of the four. The cover 62 has a box shape with an open rear surface, and an assembly protrusion (not shown) that engages with the assembly hole 64a on the inner peripheral surface of the peripheral wall.
Is formed. That is, when the body 62 is covered with the cover 62, the assembling projection engages with the assembling hole 64a in a concavo-convex manner, so that the body 61 and the cover 62 can be detachably coupled.

A frame portion 61a is formed on one surface of the peripheral wall of the body 61 so as to project forward (upward in FIG. 1) from other portions, and a plug introduction port 63 is formed in the frame portion 61a. In addition, a substantially U-shaped fixed rib 65 is formed on the inner bottom surface of the body 61 in the vicinity of the frame portion 61a, and the modular jack 6 is attached to a portion surrounded by the fixed rib 65 and the frame portion 61a. That is, the modular jack 6 is prevented from moving in the direction along the inner bottom surface of the body 61 by being surrounded by the fixed rib 65 and the frame portion 61a. Also, the fixing rib 65
Engaging projections 6 each having a claw at its tip on both side pieces
6, a pair of fixing claws 67 are formed on the remaining one piece of the fixing rib 65. The engagement protrusion 66 engages with the locking groove 6 a provided in the modular jack 6, and the fixed claw 67 engages with the peripheral surface of the modular jack 6. With this structure, the modular jack 6 is fixed to the body 61.

The cover 62 is formed with a cutout portion 62a which meshes with the frame portion 61a of the body 61, and a cutout groove 62b for pulling out the twisted pair cable 1 connected to the modular jack 6 to the outside of the housing 60. It

By the way, as shown in FIG.
A door 70 for opening and closing the plug introduction port 63 is provided inside the frame portion 61a. The door 70 includes a first door body 71 and a second door body 72 each formed in a plate shape, and a plug introduction port formed in the body 61 on the front surface (front side surface in FIG. 1) of the first door body 71. An operation protrusion 71a that partially projects from 63 is provided. Further, a pair of projecting pieces 71b is provided on both sides of the first door body 71 so as to project. The second door body 72 is arranged between the frame portion 61 a of the body 61 and the first door body 71. The first door body 71 and the second door body 72 are slidable in a state in which movement in the left-right direction is restricted by a rib (not shown) provided on the frame portion 61a of the body 61.

The opposing surfaces of the first door body 71 and the second door body 72 are engaged with the second door body 72 when the first door body 71 moves in the direction of closing the plug introduction port 63, and the first door body 71 is engaged with the second door body 72. The second door 72 also moves the plug introducing port 63 in the closing direction (first part).
An engaging projection 71c is shown as an engaging portion of the door body 71 in FIG. 3 ).

On the other hand, an external force is applied to the operation projection 71a of the first door body 71 to open the plug introduction port 63 in the first direction.
When the door body 71 is moved and a part of the plug introduction port 63 is opened, the second door body 72 comes into contact with the operation protrusion 71a and the second door body 72 can be moved together with the first door body 71. It is like this. That is, when the first door body 71 is moved so as to open the plug introduction port 63, the second door body 72 is pushed by the first door body 71 and moves in the direction in which the plug introduction port 63 is opened.

By the way, the pair of projecting pieces 71b provided on the first door body 71 respectively function as spring seats at one end of the return spring 73 which is a coil spring. A pedestal 68, which serves as a spring seat on the other end of the return spring 73, is arranged on the body 61, and the return spring 73 is formed by the pedestal 68 and the first door base 7.
By being held between the first projecting piece 71b and the first projecting piece 71b, the first door body 71 is urged in the direction of closing the plug introduction port 63.

With the above-described structure, the first door body 71 is urged by the return spring 73 in the direction to close the plug introduction port 63, and the plug introduction port 63 is closed by the first door body 71 and the second door body 72. . When an external force is applied to the operation protrusion 71a of the first door body 71 to move the plug introduction port 63 in the direction to open it, the second door body 72 is also moved to the plug introduction port 6a.
Move to the direction to open 3. That is, to connect the modular plug 8 to the modular jack 6, the modular plug 8 may be brought into contact with the operating projection 71a and the door 70 may be operated to open the plug introduction port 63. Door 70 when pulled out from modular jack 6
Is automatically closed by the spring force of the return spring 73. As described above, when the modular plug 8 is removed, by closing the plug inlet 63, it is possible to prevent dust and foreign matter from entering the modular jack 6, and increase the contact resistance between the modular plug 8 and the modular jack 6. Can be prevented.

By the way, the modular jack 6 shown in this embodiment, as shown in FIGS. 4 to 9, is a plug connection base 1 and a terminal base 2 which are molded products of an insulating synthetic resin.
With. The terminal base 2 includes a contact 41 and a terminal 42.
And a conductor 4 electrically connected to each other via a connection conductor 43.
(See FIG. 10) is held and coupled to the plug connection base 1 to form a modular jack. The conductors 4 are formed by punching out a sheet metal having elasticity, and eight conductors 4 are held on the terminal base 2. The terminal base 2 is formed of two members, a base 20 and a holding base 30, and the holding base 30 is bonded to the upper surface of the base 20.

The plug connection base 1 is a hollow body in which a plug insertion opening 11 into which a modular plug is inserted is opened in the upper front surface, and a mounting hole 12 into which the front end portion of the terminal base 2 is inserted is opened in the lower rear surface. The rear wall is formed with eight separation slits 13 that are open to the upper edge of the mounting hole 12.

The base 20 has a connecting support piece 21 that abuts the lower surface of the plug connection base 1 at the front end portion, and a holding base mounting plate 22 on which the holding base 30 is mounted at the rear end portion. The lower surface of the plug connection base 1 is formed with a connecting groove portion 14 having a width substantially equal to the left-right width of the connecting support piece 21, and a coupling protrusion 15 formed in a substantially T shape is formed on the inner bottom surface of the connecting groove portion 14. It A substantially T-shaped coupling hole 23 that can be engaged with the coupling protrusion 15 is formed in the coupling support piece 21. The coupling hole 23 is provided with a notch groove 23a which is opened in the front edge of the connecting support piece 21 as desired, and the notch groove 23a improves the flexibility of the front end portion of the connecting support piece 21. In addition, insertion locking pieces 24 are provided on both sides of the base of the connection supporting piece 21 at positions displaced upward with respect to the connection supporting piece 21, and the insertion locking pieces 24 are attached to the mounting holes formed in the plug connection base 1. 12 is inserted in the lower part. Then, the insertion locking piece 24 is locked inside the plug connection base 1, and the connection support piece 21 abuts the lower surface of the plug connection base 10, whereby the base 20 is temporarily held by the plug connection base 1. become.

On the other hand, the holding table 30 has a contact support table 31 for holding the contacts 41 at the front end thereof, and a terminal 42.
Is provided at the rear end with a terminal support base 32 protruding toward the upper surface. A lever support base 33 is provided on the upper surface of the terminal base 2 so as to project between the contact support base 31 and the terminal support base 32. A positioning groove 34 for positioning the conductor 4 is formed in the front end portion of the contact support base 31 and the lower surface of the holding base 30. In addition, the terminal support 32 is formed with a terminal insertion hole 35 penetrating vertically and through which the terminal 42 is inserted.

To connect the terminal base 2 to the plug connection base 1, the contact support base 31 is inserted into the mounting hole 12 with the base 20 and the holding base 30 adhered to each other. Terminal base 2
Engaging protrusions 31a are provided on both side surfaces of the contact support base 31, and the inner surface of the plug connection base 1 guides the terminal base 2 in a state of being engaged with the engaging protrusions 31a. Ditch 1
0a is formed. Therefore, when the terminal base 2 is moved forward in a state where the engaging protrusion 31a is engaged with the engaging groove 10a, the holding base 30 causes the holding protrusion 30 to engage with the engaging groove 31a.
The position of the base 20 is regulated by a and
Since the position is regulated by 1 and the connecting groove portion 14, the terminal base 2 can be inserted to a predetermined position while regulating the position with respect to the plug connection base 1. When the terminal base 2 is inserted to a fixed position, a lever support base 33 or the like formed on the intermediate portion of the terminal base 2 in the front-rear direction abuts the rear surface of the plug connection base 1, whereby the plug of the terminal base 2 is plugged. The amount of insertion into the connection base 1 is restricted.

Further, the coupling protrusion 1 provided on the plug connection base 1
5, the coupling hole 23 of the base 20 is engaged, and the plug connection base 1
On the other hand, the rearward movement of the terminal base 2 is prohibited. At this time, the insertion locking piece 24 of the base 20 together with the contact support piece 31 of the holder 30 attaches to the mounting hole 12 of the plug connection base 1.
Inserted in. Here, when a downward force is applied to the rear end portion of the terminal base 2, the connection support piece 21 tries to move upward with the insertion locking piece 24 as a fulcrum, but the connection support piece 21 does not move in the plug connection base 1. Since it is in contact with the lower surface, upward movement is prohibited, and consequently, the rear end portion of the terminal base 2 is prevented from moving downward. Further, when an upward force is applied to the rear end portion of the terminal base 2, the connection support piece 21 tries to move downward with the insertion locking piece 24 as a fulcrum, but the lever support base 33 is the rear surface of the plug connection base 1. The movement of the terminal base 2 is prohibited because it is in contact with the terminal base 2, and consequently the rear end of the terminal base 2 is prohibited from moving upward. Although the engagement protrusions 31a and the engagement grooves 10a also contribute to the vertical movement restriction of the terminal base 2, the vertical movement restriction is more reliably performed by the above-described action. In short, the plug connection base 1 and the terminal base 2 are joined by engaging a part of them, but they are firmly joined so that rattling does not occur.

The contacts 41 are arranged on the contact support base 31 from the front end portion to the rear upper direction, and the terminal base 2
When inserting the contact support base 31 of the above into the plug connection base 1, each contact 41 is introduced into each separation slit 13, and each contact 41 is guided by each separation slit 13. With the terminal base 2 coupled to the plug connection base 1, the rear ends of the contacts 41 are kept inserted in the separation slits 13, and the contacts 41 are separated so as not to contact each other. By thus inserting the contact 41 into the plug connection base 1, the plug insertion opening 11
The contact 41 can be elastically contacted with the contact of the modular plug inserted into the plug connection base 1 through the contact 41.

The modular jack of the illustrated example is for connecting a twisted pair cable 1 of 4 to 8 cores, and eight conductors 4 are held on the terminal base 2. Each conductor 4
The terminal 42 provided in the terminal is the terminal insertion hole 35 provided in the holding table 30.
Is inserted from below to project from the upper surface of the terminal support base 32,
It is arranged in two rows. The terminal 42 is of a press-contact type formed in a fork shape having a press-contact slit 42a whose upper edge is opened between a pair of teeth, and the press-contact slit 42a.
Is set to such a degree that both side edges of the pressure contact slit 42a are in pressure contact with the core wire of the electric wire to be connected. That is, when an electric wire having an insulation coating is press-fitted into the press-contact slit 42a from above, the insulation cover of the electric wire is cut at both side edges of the press-contact slit 42a to remove the insulation cover and press-connect the slit 42a.
A core wire is introduced into the inside of the pressure contact slit 42a, and the core wire is sandwiched between both side edges of the pressure contact slit 42a. This terminal is a known one also called an IDC terminal.

By the way, in the illustrated example, in order to connect the electric wires to the terminals 42 without using a separate tool or jig, the aligning function of holding a plurality of electric wires together and the electric wires are pressure-contact slits 42a of the terminals 42. A pair of levers 5 made of a synthetic resin molded product having a press-fitting function of being press-fitted into are provided. Although both levers 5 are formed in different shapes, they are formed in symmetrical shapes on the left and right. However, both levers 5
Is symmetrically formed as described above, so in the following,
Only one lever 5 will be described.

The lever 5 is pivotally supported via a rotary shaft 50 with respect to a bearing portion 33a formed continuously and integrally with each lever support base 33. The rotary shaft 50 is fixed through a shaft hole 51 provided in the lever 5, and together with the lever 5, the bearing portion 33a.
Rotate against. That is, the lever 5 has the bearing portion 33a.
It is rotatable around the center of the terminal base 2 and can be undulated between a position where the terminal base 2 is covered and a position where the terminal base 2 is opened. The rear surface side of the bearing portion 33a is open.

[0041] Here, the lever 5 and the plug unit connecting base 1 as shown in FIG. 5 by abutment, the maximum angle to cause the lever 5 is restricted. That is, when the lever 5 is raised in the plug connection base 1, the portion where the lever 5 abuts (that is, the upper part of the rear surface of the plug connection base 1) is the inclined surface 10b that is inclined rearward, and when the lever 5 is raised. In addition, the upper surface of the terminal base 2 is opened sufficiently wide. Since the inclined surface 10b is formed on the upper portion of the rear surface of the plug connection base 1 as described above, the range of rotation of the lever 5 can be increased, and when the lever 5 is raised, the rear surface of the lever 5 is connected to the terminal board. The table 2 can be made substantially orthogonal to the upper surface of the table 2. Also, lever 5
The upper surface of the lever 5 when the lever 5 is tilted (indicated by the solid line in FIG. 5 ) is curved so as to be convex upward at the front and rear intermediate portions. As a result, the rotary shaft 50 can be removed from the bearing portion 33a. In this way, lever 5
Since the part that is relatively distant from the rotary shaft 50 can be used as the fulcrum when removing the lever, the work of removing the lever 5 is facilitated.

By the way, the terminal support base 3 of the lever 5
On one surface on the second side, three separating plates 52 that separate and hold the electric wires connected to the terminals 42 are provided in a protruding manner. A separation passage through which each electric wire passes is formed between each side wall of the lever 5 and the separation plate 52 or between the adjacent separation plates 52, and a holding projection 53 is provided at a proper position in each separation passage. This allows the wires to be attached to and detached from the separation passage. That is, the electric wire inserted into the separation passage is held by the holding projection 53 so as not to fall off. Further, a separation hole 54 for separating and holding the tip portion of the electric wire is formed in a portion of the lever 5 near the rotation shaft 50. Therefore, the electric wires can be aligned between the separation passage and the separation hole 54. Since the work of aligning the electric wires is performed before connecting the electric wires to the terminals 42, the lever 5 is raised at this time, and the rear surface when the lever 5 is raised as described above is the upper surface of the terminal base 2. Since it is opened substantially orthogonally to, the work of passing an electric wire through the separation passage and the separation hole 54 becomes easy.

On the other hand, the lever 5 has a separation passage and a separation hole 5.
Two press-fitting grooves 55 running in the axial direction of the rotary shaft 50 are formed in a portion between the two. Each press-fit groove 55 is formed so that the tip of the terminal 42 is inserted when the lever 5 is brought close to the terminal base 22, as shown in FIG. 11, and the electric wire is pressed against the terminal 42 before and after the press-fit groove 55. I am allowed to do so. In short, when the lever is brought close to the terminal base 2 while the lever 5 holds the electric wire, the electric wire is pressed before and after the press-fitting groove 55, so that the electric wire is press-fitted into the press-contact slit 42a of the terminal 42. In this sense, the lever 5 has an electric wire aligning function and a press-fitting function.

By the way, in the lever 5, the terminal support 3
An opening 57 into which a part of the terminal support 32 is inserted is formed on one side surface of the portion corresponding to 2. this is,
This is because the left and right width of the terminal support base 32 can be made larger than that when the terminal support base 32 is housed between both side surfaces of the lever 5. Further description will be made. There is a limit to widen the left and right width of the terminal base 2, while the distance between the terminals 42 needs to be relatively large.
When the left and right width of 2 is small, the distance between the terminal 42 and the side surface of the terminal support base 32 becomes small, and the terminal support base 32 becomes thin,
The strength of the terminal support 32 cannot be sufficiently secured, and the terminal support 32 may be damaged when the electric wire is press-fitted into the terminal 42. On the other hand, as in the above configuration, the lever 5
By forming the opening 57 on one side surface, it becomes possible to widen the left and right width of the terminal support base 32 within the limited left and right width of the terminal base base 2 and improve the strength of the terminal support base 32. It can be done.

In the state in which the lever 5 is tilted, as shown in FIG. 9, the pawl 36a of the locking hook 36 that is erected on the rear surface of the terminal base 2 (holding base 30) is located on the side of the lever 5. It is adapted to engage with the locking claw 56a at the tip of the extended movement restricting piece 56 to prevent the lever 5 from being easily opened. That is, since the lever 5 has a function of pressing the electric wire as described above, by preventing the lever 5 from being opened, even if an external force is applied to the electric wire, it is difficult for the lever 5 to come off from the terminal 42. Further, when the lever 5 is tilted, the lower surface of the movement restricting piece 56 abuts on the upper surface of the base portion 38 protruding from the upper surface of the terminal base 2, and the movement of the lever 5 is restricted. That is, if the movement restricting piece 56 is not provided, the bearing portion 33a may be damaged when a large force acts on the lever 5 when the lever 5 is tilted. Since the force can be received by the movement restricting piece 56 by abutting on a part of the above, it is possible to prevent the bearing portion 33a from being damaged.

As described above, the terminal base 2 is formed by stacking and adhering the base 20 and the holding base 30, and the contact supporting base 31 provided on the holding base 30 of the terminal base 2 is formed. Since the connection support piece 21 of the base 20 is engaged with the lower surface of the plug connection base 1 while being inserted into the mounting hole 12 of the plug connection base 1, they are relatively bonded when the base 20 and the holding base 30 are bonded. It does not slide, and as a result, if the amount of adhesive applied is appropriate, the adhesive will not stick out between the base 20 and the holding table 30. In other words, it is possible to prevent the appearance of the adhesive from being spoiled and the product specifications from not being satisfied due to the adhesive protruding, which facilitates the manufacturing process and improves the yield. Further, when the electric wire is connected to the terminal 42 by the lever 5, a relatively large downward force acts on the terminal base 2, but as described above, the terminal base 2 moves up and down with respect to the plug connection base 1. It is difficult to do so, and it is possible to prevent an uncomfortable feeling when connecting the electric wire and to prevent the terminal base 2 from being damaged.

( Second Embodiment ) The base 20 and the holding base 30 may be coupled by engaging with each other. That is, as shown in FIGS. 12 to 17, the remaining three parts of the peripheral portion of one of the base 20 and the holding base 30 (the base 20 in the illustrated example) except for one side located on the lower surface side of the plug connection base 1. One coupling hook 25 is continuously provided upright on each side. In addition, a coupling groove 37 that engages with the coupling hook 25 is formed on the peripheral portion of the other side (holding table 30 in the illustrated example). A coupling claw 25 a is provided on the upper end of each coupling hook 25 so as to project inward of the base 20. In addition, a through hole 26 penetrating vertically in the base 20 is formed near the lower end of each coupling hook 25. The through hole 26 is formed for the convenience of forming the coupling hook 25a, but the notch 2 formed on both sides of the lower end of the coupling hook 25.
Along with 5b, it has a function of facilitating bending of the coupling hook 25.

Is possible. If the adhesive is not used, the adhesive does not overflow and the yield is further improved. Further, as compared with the case where the adhesive is used, the waiting time for curing the adhesive does not occur, and the productivity can be improved. If it is necessary to further increase the bonding strength between the base 20 and the holding table 30, an adhesive can be used together. Even when the adhesive is used together, there is no relative sliding process between the base 20 and the holding table 30 in the assembly process, so that the adhesive can be prevented from protruding, resulting in the conventional configuration. The yield is improved by comparison.

However, since the arrangement of the contacts 41 and the arrangement of the terminals 42 are fixed, the connecting conductors 43 are practically arranged so as to reduce crosstalk. In this case, since it is necessary to cross a part of the connection conductor 43, the connection conductor 4
Part of 3 will be arranged vertically. That is, FIG.
As shown in, a part of the connection conductor 43 is arranged in upper and lower two layers.

In order to arrange the upper and lower two layers, it is necessary to form a gap between the facing surfaces of the base 20 and the holding table 30. Therefore, a protrusion 20a is formed on a part of the upper surface of the base 20 so as to protrude higher than other portions.
The holding table 30 is placed on the above. With this configuration, the base 20 is provided at a portion where the protrusion 20a is not formed.
A gap is formed between the holding base 30 and the holding table 30, and the connection conductor 43 can be formed into two layers.

Further, the protrusion 20a is also provided below the terminal 42, and the lower end of the protrusion 20a is brought into contact with the lower end of the terminal 42 so that when the wire is press-fitted into the terminal 42, the terminal 42 is lowered.
