Fig. 2 (A) and Fig. 2 (B) are the stereograms of locked configuration that shows two connectors of first execution mode, and Fig. 3 is the drawing in side sectional elevation of the locked configuration shown in Fig. 2 (A) and Fig. 2 (B).Above-mentioned locked configuration is to be provided with symmetrically in the outside of the terminal at the two ends of terminal board column direction, only shows a wherein side locked configuration here.The flexible wrist 22 of the male connector 20 of (representing) when Fig. 2 (A) shows (representing with two pecked lines) in connector chimeric preceding (representing with solid line) and the chimeric operation on the way, chimeric the finishing of Fig. 2 (B) demonstration with solid line.
Shown in Fig. 2 (A) and Fig. 2 (B), the fixed component 14 of parent form connector 10 is to be made by metallic plate, bends to the L font towards its thickness of slab direction.Fixed component 14 has the installation portion 14A that is located at respectively along the overshooting shape on the upper and lower side edge that the chimeric direction of connector (arrow A direction) is extended, and is fixed on the housing 11 with this installation portion 14A.The part of extending along the chimeric direction of connector at fixed component 14 forms the dimetric peristome 15 of having an appointment.Among four inward flanges in the interior week that forms this peristome 15, the inward flange that is positioned at the free end side of fixed component 14 is blocked the sticking department 15A that ends as the card claw stop 23 with male connector 20 and is played a role.But, in the present embodiment, fixed component 14 usefulness rigid materials are made, and the part of extending along the chimeric direction of connector can in plate face direction (arrow B direction) elastic springing not take place because of the butt of the card claw stop 23 of above-mentioned flexible wrist 22.
The part of extending in the chimeric direction along connector of fixed component 14 is provided with the compression zone 16 by being bent to form after its plate face has been cut.This compression zone 16 extends along the chimeric direction of connector, as described later, and in that connector is chimeric when finishing, with the face of connector inboard, just compression face 16A bears the card claw stop 23 of male connector 20.This compression zone 16 as described later, when the deflection direction of displacement of flexible wrist 22 is in these flexible wrist 22 deflection deformations in the shift position and the scope between the free state position of the leading section 23B of card claw stop 23.In the present embodiment, compression zone 16 usefulness rigid materials are made, not can because of the butt of the card claw stop 23 of above-mentioned flexible wrist 22 in thickness of slab direction generation elastic springing.
The flexible wrist 22 of male connector 20 is formed with at the crooked and card claw stop 23 that extend towards the connector outside of the lower limb of this flexible wrist 22 at its leading section.This card claw stop 23 has the 23A of beveled edge portion in the chimeric direction of connector the place ahead as shown in Figure 3.Card claw stop 23 has the front end face 23B that forms as its bearing of trend front end face.This front end face 23B is formed on when connector is chimeric to be finished and the face of the compression face 16A butt of compression zone 16.
The lock out action of male connector 20 for the chimeric operation of parent form connector 10 below is described.
At first, flexible wrist 20 by the chimeric operation of connector from Fig. 2 (A) to move to chimeric direction A with the position of the connector shown in the dotted line before chimeric among solid line, Fig. 3.After the 23A of beveled edge portion of the card claw stop 23 of flexible wrist 22 is connected to the end of fixed component 14 of parent form connector, with the above-mentioned end sliding contact of said fixing member 14 in advance, flexible wrist 22 is to the direction generation elastic springing away from the part of extending towards chimeric direction A of fixed component 14.As a result, shown in two pecked lines, the leading section 23B of the card claw stop 23 of flexible wrist 22 is connected to the medial surface of fixed component 14 and becomes towards the state of the inboard deflection of connector.
When owing to the position of the sticking department 15A that proceeds to make the leading section 23B of card claw stop 23 arrive peristome 15 of the chimeric operation of connector, the elastic springing of flexible wrist 22 is disengaged and the state that affranchises, and card claw stop 23 runs through the peristome 15 of fixed component 14, the leading section 23B of card claw stop 23 is connected to the compression face 16A of compression zone 16, thereby finishes the chimeric operation of connector.As a result, only will block claw stop 23 cards, break away from each other so can prevent the connector after chimeric because the sticking department 15A of fixed component 14 extracts direction at connector.
As mentioned above, in the shift position and the scope between the free state position of the compression zone 16 of parent form connector 10 leading section 23A of card claw stop 23 when the deflection direction of displacement (arrow B direction) of blocking claw stop 23 is in the deflection deformation of flexible wrist 22.That is to say, as shown in Figure 3, on the deflection direction of displacement of flexible wrist 22, compression zone 16 for the butt position of the leading section 23B of card claw stop 23, be in the shift position Q1 and the scope between the Q2 of free state position of the position P of the compression face 16A leading section 23B of card claw stop 23 when being in 22 deflection deformations of flexible wrist.Thereby, in that connector is chimeric when finishing, when thereby the elastic deflection of the flexible wrist 22 of male connector 20 is disengaged and card claw stop 23 is moved affranchise state, than the free state position Q2 of this card claw stop 23 more on the position of front side, the compression face 16A of compression zone 16 bears the collision of the leading section 23B of this card claw stop 23 on the P of position.
Thereby, adopt the parent form connector 10 of present embodiment to change places and confirm that connector is chimeric and whether normally finish by click likeness of the deceased.And when connector during, so-called half lock-out state, then can not produce the click sound for chimerism not, perhaps the click sound is very little, can easily judge the not chimerism of connector thus.
In addition, because above-mentioned card claw stop 23 and compression zone 16 all are metal, therefore can this card claw stop 23 and compression zone 16 be electrically contacted on its bearing surface.Thereby, be connected in corresponding earthed circuit portion on the circuit substrate by compression zone 16 with parent form connector 10, also can make the object connector, be male connector 20 earth-continuities.
In occasion with two connector earth-continuities, preferably at the member that is provided with compression zone 16, be to form the ground connection foot be used for being connected to above-mentioned corresponding earthed circuit portion on the metal fixed component 14, and make its earth-continuity.By ground connection foot is set on fixed component 14, make noise signal that the contact portion at card claw stop 23 and 16 of compression zones flows mobile from the corresponding earthed circuit portion on circuit substrate of the ground connection foot of fixed component 14 that forms a member with compression zone 16.Thus, compare, can shorten the earth-continuity circuit, can prevent noise better with the situation that ground connection foot is set on other member.
In the present embodiment, but be the flexible wrist 22 of the wrist of male connector 20 being made elastic springing, and with the compression zone 16 of parent form connector 10 make not can elastic springing member, but as variation, also the above-mentioned wrist of male connector side can be made not can elastic springing member, but and the compression zone of parent form connector side is made the member of elastic springing.In this variation, the butt position of the card claw stop of above-mentioned wrist, promptly in the shift position and the scope between the free state position of leading section compression zone when the deflection direction of displacement of compression zone is in the compression zone deflection deformation of this fastener.
Thus, compression zone just moves in that connector is chimeric when finishing and elastic deflection is removed when affranchising state, than free state position more on the position of front side with card claw stop butt, thereby bear the impact pressure that comes from this card claw stop.The result is, and is same with present embodiment, can produce very big click sound, and can make compression zone be connected in corresponding earthed circuit portion on the circuit substrate, thereby makes also earth-continuity of male connector.But, also can make and be not only compression zone self and do elastic springing, and elastic springing all takes place in the fixed component integral body that is provided with compression zone.
As other variation of present embodiment, but also the wrist of male connector and the compression zone both sides of parent form connector all can be made elastic springing.In this variation, the butt position that connector is chimeric when finishing between compression member and card claw stop is in the deflection direction of displacement of above-mentioned wrist and above-mentioned compression member is in scope between the free state position of the free state position of this wrist and this compression member.
Thus, chimericly finish at connector, wrist and compression zone remove elastic deflection and move when affranchising state, this wrist and compression zone are than separately free state position more on the position of front side, and compression zone bears impact pressure with card claw stop butt from this card claw stop.As a result, same with present embodiment, can produce very big click sound, and the corresponding earthed circuit portion on the circuit substrate of compression zone can being connected in is so that male connector also is grounded conducting.But, can make compression zone itself can elastic springing yet, but makes the fixed component elastic springing that is provided with compression zone.
In the present embodiment, male connector has the card claw stop, and the parent form connector has sticking department, and as variation, also can make and fixed component is set on male connector and makes this fixed component have sticking department, and wrist is set and make this wrist have the card claw stop at the parent form connector.
＜the second execution mode 〉
In the present embodiment, the fixed component of parent form connector and casing member form a member, and this point is different with first execution mode that forms fixed component and casing member with different component.Fig. 4 shows the fixed component of present embodiment and the stereogram of casing member.In the present embodiment, all members identical with first execution mode all use identical Reference numeral and omit explanation.
As shown in Figure 4, in the present embodiment, casing member 13 is members making with a metallic plate with fixed component 14.Specifically, the part that becomes the upper surface of parent form connector 10 on this casing member 13 links in the part of extending along the terminal board column direction of the edge part in the chimeric direction of connector (arrow A direction) the place ahead and fixed component 14.By like this casing member 13 and fixed component 14 being bent to a member, the intensity of fixed component 14 and rigidity are promoted, and number of spare parts is reduced, cost can be suppressed thus, thereby the burden of part management can be reduced.
The part as parent form connector 10 lower surfaces on casing member 13 forms from the edge part in the chimeric direction of connector the place ahead and gives prominence to the ground strip 13B that extends towards this chimeric direction.At parent form connector 10 during towards the real dress of circuit substrate (not shown), ground strip 13B is installed in corresponding earthed circuit portion (not shown) on this circuit substrate by welding connecting mode, makes casing member 13 earth-continuities.Lower limb in the part of extending along the terminal board column direction of fixed component 14 forms the 14B of ground connection foot that extends downwards on position identical with above-mentioned ground strip 13B on the terminal board column direction.The 14B of this ground connection foot as shown in Figure 4, its leading section extend into the hole portion that on ground strip 13B, forms and with this ground strip 13B butt, thereby combination mechanically.By this leading section being welded in the corresponding earthed circuit portion on the circuit substrate, make the corresponding earthed circuit of fixed component 14 portion earth-continuity with this.
