It also functions as a guide surface that is in sliding contact with the second main body 152 and smoothly guides them. Further, since the narrow portion 54 a is narrower than the wide portion 154 b of the groove portion 154, both side edges of the narrow portion 54 a are tongue piece portions 54 in the fitting process between the first connector 1 and the second connector 101. Functions as a guide for facilitating entry when entering the groove 154.

  In the fitting process between the first connector 1 and the second connector 101, when the second projecting end 122 enters the projecting end recess 22, the narrow portion 54a of the tongue piece 54 becomes the wide portion. 154b enters from a portion near the second main body portion 152 and moves relatively in the groove portion 154 toward the narrow portion 154a. That is, the tongue piece portion 54 moves relative to the narrow portion 154a so as to enter the wide portion 154b of the groove portion 154 with the narrow portion 54a in the front end and the wide portion 54b in the rear end. Enter the groove 154. Therefore, when the narrow portion 54 a of the tongue piece portion 54 is narrower than the wide portion 154 b of the groove portion 154, the tongue piece portion 54 can easily enter the groove portion 154.

  In a state where the first connector 1 and the second connector 101 are completely fitted, the tongue piece 54 and the groove 154 are engaged, and both side edges of the tongue piece 54 in the width direction are opposite to both width edges of the groove 154. opposite. Specifically, as shown in FIGS. 5A to 5C, the narrow portion 54 a of the tongue piece portion 54 is accommodated in the narrow portion 154 a of the groove portion 154, and the wide portion 54 b of the tongue piece portion 54. Is accommodated in the wide portion 154b of the groove portion 154, and the step portion 54c of the tongue piece portion 54 engages with the step portion 154c of the groove portion 154. That is, the narrow part 54a, the wide part 54b, and the step part 54c of the tongue piece part 54 engage with the narrow part 154a, the wide part 154b, and the step part 154c of the groove part 154, respectively. Then, both surfaces of the tongue piece portion 54 and both surfaces of the outer plate portion 153 are substantially flush with each other.

  In addition, a concave and convex first lock latching portion 57a is formed at the tip of the first arm portion 57 of the first reinforcing bracket 51, and is latched in the first arm portion accommodating portion 26a of the first housing 11, It is designed to be held securely. Furthermore, the contact piece 58 connected to the first arm portion 57 is formed with a contact convex portion 58a, and for example, the contact with the second arm portion 157 of the second reinforcing bracket 151 can be reliably maintained. .

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

  FIG. 6 is a perspective view including a partially broken section showing the positional relationship between the first reinforcing bracket and the second reinforcing bracket in the connector fitting step in the embodiment of the present invention, and FIG. 7 is an embodiment of the present invention. FIG. 8 is a perspective view including a partially broken cross section showing the positional relationship between the first reinforcing bracket and the second reinforcing bracket in the state where the connector fitting in FIG. 8 is completed, and FIG. 8 shows the connector fitting in the embodiment of the present invention. FIG. 9 is a cross-sectional view showing the positional relationship between the first terminal and the second terminal in a completed state, and is a cross-sectional view taken along the line AA in FIG. 2, and FIG. 9 is inclined to the fitted connector in the embodiment of the present invention; It is sectional drawing which shows the positional relationship of the 1st reinforcement metal fitting when the external force to give is given.

  Here, the first connector 1 is connected to a terminal connection pad connected to a conductive trace on a first substrate (not shown) of the first terminal 61 by soldering or the like. It is assumed that the first substrate connecting portion 56 is surface-mounted on the first substrate by being connected to a fixing pad on the first substrate by soldering or the like.

  Similarly, the second connector 101 is connected by soldering or the like to the terminal connection pad connected to the conductive trace on the second substrate (not shown) of the tail 162 of the second terminal 161, and the second reinforcing bracket 151. It is assumed that the lower end of the outer plate portion 153 is surface-mounted on the second substrate by being connected to a fixing pad on the second substrate by soldering or the like.

  First, the operator sets the fitting surface of the first connector 1 and the fitting surface of the second connector 101 to face each other, and the position of the second convex portion 112 of the second connector 101 corresponds to the first connector 1. If 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, the first connector 1 and the second connector 101 The alignment of 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.

  FIG. 6 shows a state where the insertion of the second protruding end 122 into the protruding end recess 22 is started. As described above, the narrow portion 54a of the tongue piece portion 54 of the first reinforcing bracket 51 includes a bent portion, and the outer curved surface of the bent portion is outside the second protruding end portion 122 that enters the protruding end recess 22. The side surface 122b thru | or the 2nd main-body part 152 of the 2nd reinforcement metal fitting 151 is slidably contacted, and these are guided smoothly. Further, since the narrow portion 54 a is narrower than the wide portion 154 b of the groove portion 154, both side edges of the narrow portion 54 a are tongue piece portions 54 in the fitting process between the first connector 1 and the second connector 101. When entering the groove portion 154, the entry is facilitated. Furthermore, the clip piece 55 and the contact piece 58 of the first reinforcing bracket 51 are bent and connected to the upper end of the first arm portion 57 and extend downward. Therefore, the outer curved surface of the bent portion is in sliding contact with the upper surface 122a of the second projecting end 122 entering the projecting end recess 22 or the second arm 157 of the second reinforcing bracket 151, and smoothly guides them.

  Subsequently, when the first connector 1 and / or the second connector 101 is further moved in the direction approaching the other side, that is, the fitting direction, the fitting between the first connector 1 and the second connector 101 is completed, The first terminal 61 and the second terminal 161 are brought into conduction.

  FIG. 7 shows a state where the insertion of the second protruding end 122 into the protruding end recess 22 is completed. As described above, the narrow portion 54a of the tongue piece portion 54 is accommodated in the narrow portion 154a of the groove portion 154, and the wide portion 54b of the tongue piece portion 54 is accommodated in the wide portion 154b of the groove portion 154. The stepped portion 54 c of 54 is engaged with the stepped portion 154 c of the groove portion 154. That is, the narrow portion 54a, the wide portion 54b, and the stepped portion 54c of the tongue piece portion 54 of the first reinforcing bracket 51 are the narrow portion 154a, the wide portion 154b, and the stepped portion 154c of the groove portion 154 of the second reinforcing bracket 151, Each engages. Further, the clip piece 55 and the contact piece 58 of the first reinforcing bracket 51 engage with the side surface of the second arm portion 157 of the second reinforcing bracket 151.

  Further, when the fitting between the first connector 1 and the second connector 101 is completed, the left and right second convex portions 112 of the second connector 101 become the left and right concave groove portions 12a of the first connector 1, as shown in FIG. Inserted inside. 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 second terminal of the first terminal 61 are inserted. 161 is in contact with the first contact portion 165, and the second contact portion 66 of the first terminal 61 is in contact with the second contact portion 166 of the second terminal 161.

  As a result, the conductive trace connected to the terminal connection pad on the first substrate to which the tail portion 62 of the first terminal 61 is connected, and the terminal connection on the second substrate to which the tail portion 162 of the second terminal 161 is connected. The conductive trace connected to the pad conducts.

  Further, the second contact portion 66 of the first terminal 61 is engaged with the second contact convex portion 166a of the second terminal 161. As a result, the first connector 1 and the second connector 101 are locked. Therefore, even if an external force in a direction for releasing the fitting between the first connector 1 and the second connector 101 is applied, the fitting is not easily released. Can be prevented.

  By the way, as explained in the section of the problem to be solved by the invention, in the case of the conventional connector, when a force is applied to make the board on which the connector is mounted oblique, the oblique extraction is performed, Unintentional or unnecessary mating release may occur.

  On the other hand, in the present embodiment, since the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 are engaged with each other, the diagonal removal is not performed, and an unintended or unnecessary fitting is performed. There is no occurrence of a release.

  In FIG. 9, with the first connector 1 and the second connector 101 fitted, for example, via the first board and the second board on which the first connector 1 and the second connector 101 are mounted, The state where the external force which makes the 2nd connector 101 diagonal with respect to the 1st connector 1 in the width direction is given is shown. However, in the present embodiment, since the tongue piece portion 54 of the first reinforcing fitting 51 and the groove portion 154 of the second reinforcing fitting 151 are engaged, as shown in FIG. It is only slightly inclined with respect to the first connector 1 and is not greatly inclined in the width direction. Therefore, the diagonal removal is not performed, and no unintentional or unnecessary mating release occurs.

  The tongue piece 54 is a plate member extending in the thickness direction and the width direction of the first housing 11, and as shown in FIG. 7, both side edges of the wide width portion 54 b are formed on the grooves 154. Displacement is restricted facing both side edges of the wide portion 154b. In particular, the stepped portion 54c located at the upper end of the side edge of the wide portion 54b faces the stepped portion 154c located at the upper end of the side edge of the widened portion 154b, and the portion near the lower end of the side edge of the widened portion 54b is a groove portion. It faces the lower end of the side edge of the wide portion 154b of 154.

  Therefore, the external force that makes the second connector 101 slant relative to the first connector 1 in the width direction, that is, the groove 154 is rotated with respect to the tongue piece 54 in the fracture surface shown in FIG. Even when such an external force is applied, the displacement in the rotational direction of the lower end of one stepped portion 154c located on the diagonal line of the wide portion 154b of the groove portion 154 and the other side edge is mainly the stepped portion of the opposing tongue piece portion 54. By being blocked by the side edges of the portion 54c and the wide portion 54b, rotation of the groove portion 154 relative to the tongue piece portion 54 is prevented. In this case, the force that prevents the displacement in the rotational direction is a moment, and is proportional to the distance from the center of rotation to the point of action, so the stepped portion 54c and the wide portion 54b of the tongue piece portion 54 located on the diagonal line of the wide portion 154b. It turns out that the force which prevents the displacement of the rotation direction exhibited by the side edge of the part 54b is large. Therefore, even if the external force that makes the second connector 101 oblique to the first connector 1 in the width direction is large, the second connector 101 becomes oblique to the first connector 1. Can be prevented.

  Further, although it is narrower than the wide portion 154 b of the groove portion 154, the side edge of the narrow portion 154 a is also prevented from being displaced by the side edge of the narrow portion 54 a of the tongue piece portion 54. Can be reliably prevented from being inclined with respect to the first connector 1.

  Furthermore, since the step portion 154c of the groove portion 154 is engaged with the step portion 54c of the tongue piece portion 54, the displacement of the groove portion 154 with respect to the tongue piece portion 54 can be more effectively prevented. Therefore, the second connector 101 can be more reliably prevented from being inclined with respect to the first connector 1.

  Furthermore, the clip piece 55 of the first reinforcing bracket 51 is engaged with the side surface of the second arm portion 157 of the second reinforcing bracket 151 outside the tongue piece 54 and the groove portion 154 in the width direction. The second reinforcing bracket 151 is prevented from being displaced in the rotational direction with respect to the first reinforcing bracket 51. Therefore, the second connector 101 can be more reliably prevented from being inclined with respect to the first connector 1.

  Further, the outer plate portion 153 of the second reinforcing metal fitting 151 extends along the outer side surface 122b of the second protruding end portion 122, and both side edges in the width direction are accommodated in the second metal fitting holding end surface concave portion 126b. Since it is held, displacement in the plate thickness direction, that is, the longitudinal direction of the second housing 111 is prevented. Accordingly, each part of the groove part 154 formed in the outer plate part 153 is not displaced in the longitudinal direction of the second housing 111.

  On the other hand, the tongue piece 54 has its front end portion entering and engaged with the recess 22a of the protruding end recess 22 and one surface thereof (the surface on the outer side in the longitudinal direction of the first connector 1) is the protruding end recess 22. The inner side surface 21c, more specifically, along the surface of the convex portion 21d formed on the inner side surface 21c, the displacement in the plate thickness direction, that is, the longitudinal direction of the first housing 11 is prevented. Yes. Further, when the tongue piece 54 enters the groove 154, the other surface (the inner surface in the longitudinal direction of the first connector 1) is the bottom surface of the groove 154, and the outer surface 122 b of the second protruding end 122. Therefore, displacement in the longitudinal direction of the first housing 11 is prevented. Therefore, each portion of the tongue piece portion 54 is not displaced with respect to the longitudinal direction of the first housing 11.

  Therefore, in a state where the first connector 1 and the second connector 101 are fitted, each portion of the tongue piece portion 54 of the first reinforcing bracket 51 and each portion of the groove portion 154 of the second reinforcing bracket 151 are Also, the first housing 11 and the second housing 111 are not displaced in the longitudinal direction. Therefore, even when an external force is applied, the narrow portion 54a, the wide portion 54b and the step portion 54c of the tongue piece portion 54 of the first reinforcing bracket 51, and the narrow portion 154a and the wide portion of the groove portion 154 of the second reinforcing bracket 151 are provided. Since the engagement with 154b and the stepped portion 154c is not released, the second connector 101 can be prevented from being inclined with respect to the first connector 1.

  In addition, although the tongue piece part 54 was provided with the narrow part 54a, the wide part 54b, and the level | step-difference part 54c here, and the groove part 154 demonstrated the example provided with the narrow part 154a, the wide part 154b, and the level | step-difference part 154c, The tongue piece portion 54 and the groove portion 154 may have any shape as long as both side edges in the width direction face each other when engaged, for example, the width may be uniform. .

  As described above, in the present embodiment, the connector includes the first connector 61 including the first terminal 61 and the first housing 11 including the first protruding end portions 21 formed at both ends in the longitudinal direction, and the first terminal. And a second connector 101 including a second housing 161 including a second projecting end portion 122 that is formed at both ends in the longitudinal direction and is engaged with the first projecting end portion 21. Yes. A first reinforcing bracket 51 and a second reinforcing bracket 151 are attached to the first protruding end portion 21 and the second protruding end portion 122, and the first reinforcing bracket 51 extends in the thickness direction of the first housing 11. The tongue piece 54 is a plate member extending also in the width direction of the first housing 11, and the second reinforcing metal fitting 151 extends in the thickness direction and the width direction of the second housing 111. When the fitting between the first connector 1 and the second connector 101 is completed, the outer plate portion 153 and the groove portion 154 extending in the thickness direction of the second housing 111 formed in the outer plate portion 153 are included. The tongue piece portion 54 and the groove portion 154 are engaged, and both side edges in the width direction of the tongue piece portion 54 are opposed to both side edges in the width direction of the groove portion 154.

  Thereby, it can prevent that the 1st reinforcement metal fitting 51 and the 2nd reinforcement metal fitting 151 with which the tongue piece part 54 and the groove part 154 engaged were inclined in the width direction. And it can prevent that the 1st connector 1 and the 2nd connector 101 which were mutually fitted incline in the width direction. Therefore, the fitting between the first connector 1 and the second connector 101 is reliably held, and the reliability can be improved.

  Further, when the fitting of the first connector 1 and the second connector 101 is completed, both surfaces of the tongue piece portion 54 and both surfaces of the outer plate portion 153 are substantially flush with each other. Therefore, since the both lateral edges of the tongue piece 54 and the both lateral edges of the groove 154 are opposed to each other, the displacement of the groove 154 in the rotational direction with respect to the tongue piece 54 is prevented. A large moment for preventing the displacement can be generated.

  Further, the tongue piece portion 54 includes a narrow portion 54 a, a wide portion 54 b, and a step portion 54 c formed at the boundary between the narrow portion 54 a and the wide portion 54 b, and the groove portion 154 is formed on the tongue piece portion 54. It includes a narrow portion 154a, a wide portion 154b, and a step portion 154c that engage with the narrow portion 54a, the wide portion 54b, and the step portion 54c, respectively. Therefore, the displacement of the groove portion 154 with respect to the tongue piece portion 54 can be effectively prevented, and the second connector 101 can be more reliably prevented from being inclined with respect to the first connector 1.

  Further, when the first connector 1 and the second connector 101 are fitted, the tongue piece portion 54 enters from the wide portion 154b of the groove portion 154 so that the narrow portion 54a is the front end and the wide portion 54b is the rear end. Then, it moves relatively toward the narrow portion 154a and enters the groove portion 154. Thereby, since the narrow part 54a of the tongue piece part 54 functions as a guide, the tongue piece part 54 can be easily entered into the groove part 154.

  Further, the tongue piece portion 54 extends along the inner side surface 21 c of the first protruding end portion 21, and the outer plate portion 153 extends along the outer side surface 122 b of the second protruding end portion 122. This prevents the tongue piece 54 and the groove 154 from being displaced in the longitudinal direction of the first housing 11 and the second housing 111, so that the engagement between the tongue piece 54 and the groove 154 is not released. .
