  The second terminal 161 is inserted into the second terminal accommodating cavity 115 from the fitting surface 111a side, and the held portion 163 is formed on the outer side surface of the second convex portion 112 in the second terminal accommodating cavity 115. The second housing 111 is fixed to the second housing 111 by being accommodated in the portion formed and sandwiched by the side walls from both sides. In this state, that is, in a state where the second terminal 161 is loaded in the second housing 111, the surfaces of the first contact portion 165, the connection portion 164, and the second contact portion 166 are fitted to the respective side surfaces of the second convex portion 112. The surface is exposed. A plurality of the second terminal accommodating cavities 115 are formed on each second convex portion 112 at a predetermined pitch. A plurality of second terminals 161 accommodated in each of the second terminal accommodating cavities 115 are also arranged on the second convex portions 112 at a similar pitch. In the example shown in the figure, for convenience of explanation, two second terminal accommodating cavities 115 are formed on each second convex portion 112, but the number thereof may be three or more. Along with the pitch, it can be set arbitrarily.

The second projecting end portion 122 is a thick member that extends in the width direction of the second housing 111 and has both ends connected to both ends in the longitudinal direction of the second convex portions 112. And the said 2nd protrusion end part 122 is inserted in the protrusion end recessed part 22 of the 1st protrusion end part 21 with which the said 1st connector 1 is provided in the state in which the 1st connector 1 and the 2nd connector 101 were fitted. It functions as an insertion convex part.

  Next, an operation of fitting the first connector 1 and the second connector 101 having the above-described configuration will be described.

  FIG. 5 is a perspective view showing a state in which the first connector and the second connector are fitted to each other in the first embodiment of the present invention. In addition, in the figure, (a) is the figure seen from diagonally upward, (b) is the figure seen from diagonally below.

  Here, the first connector 1 has the tail portion 62 of the first terminal 61 connected to a connection pad connected to a conductive trace (not shown) of the first substrate by soldering or the like, and at least the first reinforcing metal fitting 51 has a first connection. It is assumed that the lower end of one center leg 55 is surface-mounted on the first substrate by being connected to a connection pad connected to the conductive trace of the first substrate by soldering or the like. The conductive trace connected to the connection pad to which the tail portion 62 is connected is a signal line, and the conductive trace connected to the connection pad to which the lower end of the first central leg 55 is connected is a power line. It shall be. Further, the connection pads to which the first central leg portions 55 of the left and right first reinforcing metal fittings 51 accommodated in the first metal fitting holding recesses 26 are respectively connected are separated from each other. Accordingly, it is assumed that each of the four power lines is connected to each of the total four first reinforcing brackets 51 provided in the first connector 1.

  Similarly, the second connector 101 has the tail 162 of the second terminal 161 connected to a connection pad connected to a conductive trace of a second substrate (not shown) by soldering or the like, and the tail of the second reinforcing member 151. It is assumed that 156 is surface-mounted on the second substrate by being connected to connection pads connected to the conductive traces of the second substrate by soldering or the like. The conductive trace connected to the connection pad to which the tail portion 162 of the second terminal 161 is connected is a signal line, and is connected to the connection pad to which the tail portion 156 of the second reinforcing metal fitting 151 is connected. The conductive trace shall be a power line. Accordingly, it is assumed that each of the four power lines is connected to each of the total of the second reinforcing metal fittings 151 included in the second connector 101.

  First, the operator makes the fitting surface 11a of the first housing 11 of the first connector 1 and the fitting surface 111a of the second housing 111 of the second connector 101 face each other, and the second protrusion of the second connector 101 is made. The position of the portion 112 matches the position of the corresponding recessed groove portion 12 a of the first connector 1, and the position of the second protruding end portion 122 of the second connector 101 matches the position of the corresponding protruding end recessed portion 22 of the first connector 1. Then, the alignment between the first connector 1 and the second connector 101 is completed.

  In this state, when the first connector 1 and / or the second connector 101 is moved in the direction approaching the other side, that is, in the fitting direction, the second convex portion 112 and the second projecting end portion 122 of the second connector 101. Is inserted into the recessed groove portion 12 a and the protruding end recessed portion 22 of the first connector 1. Thereby, as FIG. 5 shows, when the fitting of the 1st connector 1 and the 2nd connector 101 is completed, it will be in the state which the 1st terminal 61 and the 2nd terminal 161 electrically conducted.

  Specifically, the second terminal 161 of the second connector 101 is inserted between the first contact portion 65 and the second contact portion 66 of each first terminal 61, and the first contact portion 65 and the first contact portion 65 of the first terminal 61 are inserted. The first contact portion 165 of the two terminal 161 comes into contact with the second contact portion 66 of the first terminal 61 and the second contact portion 166 of the second terminal 161 comes into contact with each other. As a result, the conductive trace connected to the connection pad on the first substrate to which the tail portion 62 of the first terminal 61 is connected, and the connection pad on the second substrate to which the tail portion 162 of the second terminal 161 is connected. The connected conductive traces conduct. In this case, since the first terminal 61 and the second terminal 161 are in a multipoint contact, the conduction state is reliably maintained.

  Moreover, the 1st reinforcement metal fitting 51 with which the 1st connector 1 is provided and the 2nd reinforcement metal fitting 151 with which the 2nd connector 101 is provided will be in the mutually engaged state. Thereby, the 1st reinforcement metal fitting 51 and the 2nd reinforcement metal fitting 151 will be in the state connected, and conduction | electrical_connection of four electric power lines is maintained.

  Specifically, the second reinforcement fitting 151 of the second connector 101 is inserted between the first contact portion 58d and the second contact portion 58a in the first contact arm portion 58 of each first reinforcement fitting 51, and the first reinforcement. The first contact portion 58d of the metal fitting 51 and the first contact portion 153 of the second reinforcement metal fitting 151 are in contact with each other, and the second contact portion 58a of the first reinforcement metal fitting 51 and the second contact portion 157 of the second reinforcement metal fitting 151 are in contact with each other. Contact. As a result, the conductive trace connected to the connection pad on the first substrate to which the first central leg portion 55 of the first reinforcing bracket 51 is connected and the second substrate to which the tail portion 156 of the second reinforcing bracket 151 is connected. The conductive trace connected to the upper connection pad conducts. In this case, since the first reinforcing bracket 51 and the second reinforcing bracket 151 are in a multipoint contact, the conduction state is reliably maintained.

  Further, the first contact portion 58d and the second contact portion 58a sandwich the second reinforcing metal fitting 151 from both sides by the function of the first contact arm portion 58 as a spring portion. Furthermore, the second contact portion 58 a of the first reinforcing bracket 51 engages with a second contact recess 157 a formed on the surface of the second contact portion 157 of the second reinforcing bracket 151. As a result, the second reinforcing bracket 151 is firmly held by the first reinforcing bracket 51, so that the second reinforcing bracket 151 is prevented from detaching from the first reinforcing bracket 51, and the first connector 1 and the second connector 101. Is securely maintained.

  Further, the first contact arm portion 58 functions as a spring portion, even if the second reinforcement fitting 151 is displaced relative to the first reinforcement fitting 51 in the width direction of the first housing 11. 58d and the 2nd contact part 58a can maintain the contact state with the 1st contact part 153 and the 2nd contact part 157 of the 2nd reinforcement metal fitting 151. FIG. Therefore, vibrations and impacts generated when the electronic device or the like on which the first substrate and the second substrate are mounted fall or receive external force are transmitted, and the second reinforcing bracket 151 is transmitted to the first reinforcing bracket 51. Even when the first displacement is relatively displaced in the width direction of the first housing 11, the conduction state between the first reinforcement fitting 51 and the second reinforcement fitting 151 can be maintained, so conduction is temporarily interrupted. The so-called instantaneous interruption does not occur.

  Further, in order to release the fitting between the first connector 1 and the second connector 101, the first connector 1 and / or the second connector 101 is moved away from the mating side, that is, in the anti-fitting direction. A force in the direction of pulling out from the recessed groove portion 12a of the first housing 11 acts on the first contact arm portion 58 of the first reinforcement bracket 51 that holds the second reinforcement bracket 151 firmly. However, in this case, the distal end, that is, the upper end of the locking portion 58e of the first contact arm portion 58 is locked to the upper end wall 13b of the locking portion receiving groove 13a of the first housing 11, and thus the first contact arm portion 58. Is prevented from being displaced in the direction of the fitting surface 11a, and the first contact arm portion 58 is reliably prevented from being extracted from the concave groove portion 12a.

  As described above, in the present embodiment, the first connector 1 includes the first housing 11, the first terminal 61 loaded in the first housing 11, and the first reinforcing bracket 51 loaded in the first housing 11. With. The first housing 11 includes first projecting end portions 21 formed at both ends in the longitudinal direction, and fits with the second housing 111 of the second connector 101, and the first reinforcing bracket 51 is connected to the first housing 11.

The first contact arm portion 58 is attached to the left and right sides of the first projecting end portion 21. The first contact arm portion 58 includes a first contact portion 58d and a second contact portion 58a facing each other, and includes a first housing. 11 is engaged with the second housing 111 of the second connector 101, the second reinforcing metal fitting 151 loaded in the second housing 111 is inserted between the first contact portion 58d and the second contact portion 58a, and the first The contact part 58d and the second contact part 58 It refers to sandwich the second reinforcing brackets 151 from both sides respectively contacting with the first contact portion 153 of the second reinforcing brackets 151 and the second contact portion 157.

  Thereby, the engagement state of the 1st reinforcement metal fitting 51 and the 2nd reinforcement metal fitting 151 can be maintained reliably, the fitting with the 1st connector 1 and the 2nd connector 101 is hold | maintained reliably, and reliability is improved. Can be improved.

  Further, the first main body portion 52 and the first side plate portion 57 of each first reinforcing bracket 51 have an L-shape when viewed from the fitting surface 11 a side of the first housing 11. Thereby, since the first reinforcing bracket 51 has high rigidity and is difficult to be deformed, the strength of the first housing 11 loaded with the first reinforcing bracket 51 is effectively reinforced.

  Further, the first reinforcing bracket 51 includes a first central leg portion 55 or a first side leg portion 56 connected to the lower end of the first main body portion 52 or the first side plate portion 57. Thereby, the 1st center leg part 55 or the 1st side leg part 56 can be connected to the connection pad of a 1st board | substrate by soldering etc., and the mounting to the 1st board | substrate of the 1st connector 1 is reliable It can be.

  Further, the first central leg 55 or the first side leg 56 is electrically connected to a connection pad on the first substrate, and the first reinforcing bracket 51 is a component for connecting an electric circuit together with the second reinforcing bracket 151. Function. Thereby, four electric circuits can be connected by a total of the four first reinforcing brackets 51 included in one first connector 1.

  Further, the first housing 11 includes a recessed groove portion 12a into which the second reinforcing metal fitting 151 is inserted, and contact arm portion accommodating cavities 16 formed on both sides of the recessed groove portion 12a. At least a part of the contact part 58d and the second contact part 58a is accommodated in the contact arm accommodating cavity 16. Therefore, the displacement of the first contact portion 58d and the second contact portion 58a in the longitudinal direction of the first housing 11 is prevented, and the engagement state between the first reinforcement fitting 51 and the second reinforcement fitting 151 becomes more reliable. The fitting between the first connector 1 and the second connector 101 becomes strong.

  Further, the first contact arm portion 58 includes a connection wall portion 58c connected to the first contact portion 58d and a locking portion 58e protruding from the connection wall portion 58c, and is a contact formed on one side of the concave groove portion 12a. A locking portion receiving groove 13a is formed on the wall surface of the arm portion receiving inner cavity 16a, and the locking portion 58e is received in the locking portion receiving groove 13a and locked with the upper end wall 13b of the locking portion receiving groove 13a. It becomes possible. As a result, even when the fitting between the first connector 1 and the second connector 101 is released, the upper end is locked to the upper end wall 13b of the locking portion receiving groove 13a of the first housing 11, so that the first contact arm Displacement of the portion 58 in the direction of the fitting surface 11a is prevented, and the first contact arm portion 58 is reliably prevented from being extracted from the concave groove portion 12a.

  Next, a second embodiment of the present invention will be described. In addition, about the thing which has the same structure as 1st Embodiment, the description is abbreviate | omitted by providing the same code | symbol. The description of the same operation and the same effect as those of the first embodiment is also omitted.

  FIG. 6 is a perspective view of the first connector according to the second embodiment of the present invention, FIG. 7 is an exploded view of the first connector according to the second embodiment of the present invention as viewed obliquely from above, and FIG. 8 is the present invention. It is the exploded view seen from the slanting lower part of the 1st connector in the 2nd embodiment. In FIG. 6, (a) is a diagram viewed from diagonally above, and (b) is a diagram viewed from diagonally below.

  In the present embodiment, the first reinforcing bracket 51 of the first connector 1 has a shape in which the two first reinforcing brackets 51 in the first embodiment are connected. Specifically, as shown in the figure, the first side plate portions 57 of the first reinforcing metal fittings 51 located at both ends in the longitudinal direction of the first housing 11 are connected to each other by a band plate-like connection portion 59. It is in a state.

  Therefore, the first reinforcing bracket 51 in the present embodiment is a pair of left and right members, each of which includes two first main body portions 52, two first side plate portions 57, and two first side leg portions. 56, two first central leg portions 55, two housing protection pieces 57b, and one connecting portion 59. The first main body portion 52 and the first side plate portion 57 that are located at both ends in the longitudinal direction of the first housing 11 and are L-shaped when viewed from the fitting surface 11 a side are the longitudinal lengths of the first housing 11. Since it is connected by the connecting portion 59 located in the central portion in the direction, the first main body portion 52, the first side plate portion 57, and the connecting portion 59 are viewed from the fitting surface 11a side in the entire first reinforcing bracket 51. It is U-shaped.

  The shapes of the two first reinforcing brackets 51 are bilaterally symmetric with respect to the center line extending in the longitudinal direction of the first housing 11. That is, the left and right first reinforcing brackets 51 are mirror images of each other with respect to a plane that divides the first housing 11 into left and right.

  In addition, the side wall portion 14 of the first housing 11 in the present embodiment has an outer portion removed in order to accommodate the connecting portion 59, as compared with the side wall portion 14 in the first embodiment. The dimension about the width direction of 1 housing 11 is shortened, and it is thin. The outer side surface 14a of the side wall portion 14 is formed to be flush with the wall surface of the side plate portion accommodating cavity 26d. As a result, when the first reinforcing metal fitting 51 is accommodated in the first metal fitting holding recess 26, the inner surface in the width direction of the first housing 11 in the connecting portion 59 is formed on the side wall portion 14 as shown in FIG. 6. It will be in the state which adjoined or contacted the outer surface 14a.

  Since the first main body 52, the first side plate portion 57, and the connecting portion 59 connected to each other have a U-shape, the first reinforcing metal fitting 51 has high rigidity and is difficult to be deformed. Therefore, the strength of the first housing 11 is more effectively reinforced by housing the first reinforcing bracket 51 in the first bracket holding recess 26.

  In the present embodiment, since the number of the first reinforcing brackets 51 is two, the connection pads to which the first central leg portions 55 of the left and right first reinforcing brackets 51 are respectively connected are separated from each other. Even if each of the first reinforcing brackets 51 functions as a connection circuit component for connecting each circuit, the circuits that can be connected by all the first reinforcing brackets 51 provided in one first connector 1 are as follows. There will be two.

  In addition, since the first terminal housing outer cavity 15 b in which the held portion 63 of the first terminal 61 is housed is formed on the inner side surface of the side wall portion 14, the connecting portion 59 has a width of the first housing 11. With respect to the direction, it is located outside the held portion 63 and does not contact the first terminal 61. As described above, the strip plate-like connecting portion 59 extending in the longitudinal direction of the first housing 11 covers the outside of the plurality of first terminals 61 arranged in line in the longitudinal direction of the first housing 11. As a result, the first terminal 61 is electromagnetically shielded by the connecting portion 59, and is less susceptible to external noise and radio waves, and noise and radio waves from the first terminal 61 to the outside are less likely to be affected. Release is also suppressed.

  Note that the configuration of other points of the first connector 1 is the same as that of the first embodiment, and a description thereof will be omitted. The second connector 101 is the same as that in the first embodiment, and a description thereof will be omitted. Furthermore, since the operation | movement etc. which fit the 1st connector 1 and the 2nd connector 101 are the same as that of the said 1st Embodiment, the description is abbreviate | omitted.

  As described above, in the present embodiment, the first reinforcing brackets 51 attached to the left and right of the first projecting end portion 21 formed at both ends in the longitudinal direction of the first housing 11 connect the first side plate portion 57. Are connected to each other by a connecting portion 59. Thereby, the intensity | strength of the 1st reinforcement bracket 51 improves and the intensity | strength of the 1st housing 11 in which the 1st reinforcement bracket 51 was loaded is more effectively reinforced. Furthermore, since the left and right first reinforcing brackets 51 are separated, for example, even if the first substrate is bent or distorted and deformed somewhat, the first housing 11 is deformed following the deformation. Therefore, the first housing 11 loaded with the first reinforcing metal fitting 51 has both flexibility and rigidity.

  The first terminals 61 are arranged side by side in the longitudinal direction of the first housing 11, and the connecting portion 59 extends in the longitudinal direction of the first housing 11 and covers the outside of the first terminal 61. As a result, the first terminal 61 is electromagnetically shielded by the connecting portion 59 and is less susceptible to external noise and radio waves.

  In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.

  The present invention can be applied to a connector.
