In the figure, reference numeral 1 denotes a first connector as one of a pair of board-to-board connectors, which are connectors in this embodiment. The first connector 1 is a surface-mounted connector mounted on the surface of a first substrate (not shown) serving as a mounting member, and is mated with a second connector 101 serving as a mating connector to be described later. be. The second connector 101 is the other of a pair of board-to-board connectors, and is a surface mount type connector mounted on the surface of a second board (not shown) serving as a mounting member.

Note that the first connector 1 and the second connector 101 in the present embodiment are preferably used for electrically connecting the first board and the second board as boards, but other members can also be used to electrically connect the The first substrate and the second substrate are, for example, a printed circuit board, a flexible flat cable (FFC), a flexible circuit board (FPC), etc. used in electronic equipment, etc., but may be any type of substrate. .

In the present embodiment, expressions indicating directions such as up, down, left, right, front, and rear used to describe the configuration and operation of each part of the first connector 1 and the second connector 101 are It is not absolute but relative, and is appropriate when each part of the first connector 1 and the second connector 101 is in the posture shown in the figure, but if the posture changes, the posture may change. It should be interpreted with change according to change.

The first connector 1 is constructed by connecting a pair of left and right half-body portions, that is, a left half-body portion 10A and a right half-body portion 10B with a first reinforcing metal fitting 51 as a reinforcing metal fitting. . Since the left half body 10A and the right half body 10B are the same member arranged to face each other in the left and right direction, they will be described as the half body 10 when collectively described. The left half body portion 10A and the right half body portion 10B each have a portal shape in plan view (the shape projected onto the XY plane), and the left half body portion 10A and the right half body portion 10B are joined together. 10B is an elongated recessed groove 13 extending in the longitudinal direction (X-axis direction) of the first connector 1 . The concave groove portion 13 is a through hole that is open on the upper and lower surfaces of the first connector 1 .

The half-body portion 10 is integrally formed of an insulating material such as synthetic resin, and has a first housing 11 as a connector main body having a portal shape in plan view. Each first housing 11 has an elongated band-shaped bottom plate portion 17 extending in the longitudinal direction (X-axis direction) of the first housing 11, and the first housing 11 integrally formed on the upper surface of the bottom plate portion 17. and a first projection 12 as an elongated projection extending in the longitudinal direction. The first convex portion 12 is a member having a cross-sectional shape like an upside-down U-shape, and includes a curved fitting surface 12a located on the upper side (the Z-axis positive direction side) and the fitting surface 12a. It has an outer surface 12b and an inner surface 12c connected to the left and right sides of the surface 12a. The outer side surface 12 b and the inner side surface 12 c are a pair of planes parallel to each other and extending in the longitudinal direction of the first housing 11 . In addition, since the dimension in the width direction (Y-axis direction) of the first protrusion 12 is shorter than the dimension in the width direction of the bottom plate portion 17, the bottom plate portion 17 protrude outward in the width direction from the outer side surface 12b and the inner side surface 12c. A lower surface of the bottom plate portion 17 is a mounting surface 17a of the first housing 11 facing the surface of the first substrate.

A first terminal 61 as a terminal is arranged on each first convex portion 12 . A plurality of first terminals 61 (26 in the example shown in the drawing) are arranged at a predetermined pitch. The first terminal 61 is a member integrally formed by punching, bending, or otherwise processing a conductive metal plate. A tail portion 62 connected to one end of the main body portion 63, a vertically extending contact portion 65 connected to the other end of the main body portion 63 by bending at an angle of approximately 90 degrees, and an upper end of the contact portion 65 being substantially and an upper end 64 connected at a 90 degree bend.

The body portion 63 is a portion embedded and held in the bottom plate portion 17 . The tail portion 62 extends outward in the width direction from the bottom plate portion 17 and is connected by soldering or the like to connection pads connected to the conductive traces of the first substrate. Note that the conductive traces are typically signal lines. Further, the contact portion 65 is a portion that contacts a second terminal 161 of the second connector 101, which will be described later, when the first connector 1 and the second connector 101 are fitted together. contact recesses 65a.

The first terminal 61 is integrated with the first housing 11 by a molding method called overmolding or insert molding. That is, the first housing 11 is molded by filling an insulating material into a mold cavity in which the first terminals 61 are set in advance. As a result, the lower surfaces of the main body portion 63 and the tail portion 62 of the first terminal 61 are exposed on the mounting surface 17 a of the bottom plate portion 17 , and the surfaces of the contact portion 65 and the upper end portion 64 are exposed on the outer surface 12 b or the outer surface 12 b of the first convex portion 12 . It is integrally attached to the first housing 11 while being exposed on the inner surface 12c and the fitting surface 12a.

Also, the first terminals 61 attached to each first protrusion 12 are oriented such that the postures of adjacent terminals are opposite to each other with respect to the width direction of the first protrusion 12 . In the example shown in FIG. 4, among the first terminals 61 attached to the first convex portion 12 of the left half body portion 10A, the posture of the first terminal 61 located at the front end (X-axis positive direction end) is is oriented so as to protrude outward (Y-axis positive direction side), whereas the first terminal 61 located second from the front end is oriented so that the tail portion 62 protrudes inward (Y-axis negative direction). direction side). Since the first terminals 61 are attached to the first projections 12 alternately in opposite directions, the pitch of the tails 62 protruding from both sides of the first projections 12 is , which is twice the pitch of the first terminals 61 . Therefore, connection work such as soldering to the connection pads of the first substrate can be easily performed. Also, the pitch of the contact portions 65 exposed on the outer surface 12 b of the first convex portion 12 and the pitch of the contact portions 65 exposed on the inner surface 12 c are also twice the pitch of the first terminals 61 .

Since the first terminal 61 is a member that is integrated with the first housing 11 by a molding method called overmolding or insert molding, it does not exist apart from the first housing 11. For convenience of explanation, it should be noted that in FIG.

At both longitudinal ends of the first convex portion 12, first projecting end portions 18, which are main body end portions functioning as fitting guide portions, are arranged. The first protruding end portions 18 are members connected to both longitudinal ends of each first protruding portion 12, and are in a state in which the left half body portion 10A and the right half body portion 10B are butted against each other, that is, left and right first projecting ends 18 are connected to each other. 1 housings 11 are formed in a state in which they are butted against each other. The first protruding end portion 18 is inserted into a fitting recess 122 of a second protruding end portion 121 of the first connector 101, which will be described later, in a state where the first connector 1 and the second connector 101 are fitted together. It functions as an insertion protrusion to be inserted. A first reinforcing metal fitting 51 is attached to the first projecting end portion 18 .

Also, the first projecting end portion 18 is constituted by the extended end portions 14 and the end wall portions 15 of the left and right half-body portions 10 . Extending end portions 14 extending in the longitudinal direction are integrally connected to both longitudinal ends of the first convex portion 12 of each half portion 10 , and each extending end portion 14 has a width of the first convex portion 12 . The end wall portions 15 extending in the direction are integrally connected to each other. The end wall portion 15 of the left half body portion 10A extends rightward (negative Y-axis direction), and the end wall portion 15 of the right half body portion 10B extends leftward (positive Y-axis direction). is extended. The end walls 15 of the half-body portions 10 arranged to face each other in the left-right direction extend toward the other half-body portion 10 . An end surface of the end wall portion 15 facing the mating half portion 10 functions as a coupling surface 15d.

Each extension end 14 is connected to a thick portion 14e having a large width (large dimension in the Y-axis direction) and a lower side of the thick portion 14e (negative Z-axis direction side). , and a thin portion 14f having a smaller thickness (smaller dimension in the Y-axis direction). The outer surface 14b of the extension end 14 includes an outer convex surface 14b1 corresponding to the thick portion 14e and an outer concave surface 14b2 corresponding to the thin portion 14f. The outer concave surface 14b2 is recessed so as to be located inside the first housing 11 in the width direction (Y-axis direction) of the outer convex surface 14b1. Since the entire outer surface 14b of the extension end portion 14 is recessed so as to be positioned more inward in the width direction of the first housing 11 than the outer surface 12b of the first convex portion 12, the outer convex surface 14b1 is also the first convex. It is recessed so as to be located inside the first housing 11 in the width direction from the outer surface 12 b of the portion 12 .

In addition, each end wall portion 15 includes a thick portion 15e having a large width (large dimension in the X-axis direction) and a thinner portion connected to the lower side of the thick portion 15e. and a thin portion 15f (having a smaller dimension in the X-axis direction). The outer surface 15b of the end wall portion 15 includes an outer convex surface 15b1 corresponding to the thick portion 15e and an outer concave surface 15b2 corresponding to the thin portion 15f. The outer concave surface 15b2 is recessed so as to be located inside the first housing 11 in the longitudinal direction (X-axis direction) of the outer convex surface 15b1. Since the entire outer surface 15b of the end wall portion 15 is recessed so as to be positioned inward in the longitudinal direction of the first housing 11 from the end surface 14d of the extended end portion 14, the outer convex surface 15b1 is also located on the extended end portion 14. It is recessed so as to be located inside the first housing 11 in the longitudinal direction from the end face 14d.

Further, each end wall portion 15 includes an inner end portion 15g protruding inwardly in the longitudinal direction of the first housing 11 in the vicinity of the connecting portion with the extension end portion 14 . An end wall base inner side surface 15h, which is an inner side surface of the inner end portion 15g, is a surface exposed in the concave groove portion 13 and is a flat surface extending in the vertical direction (Z-axis direction). The inner side surface 15c of the end wall portion 15 includes an inner convex surface 15c1 corresponding to the thick portion 15e and an inner concave surface 15c2 corresponding to the thin portion 15f. The inner concave surface 15c2 is recessed so as to be positioned further outward in the longitudinal direction of the first housing 11 than the inner convex surface 15c1. Since the entire inner side surface 15c of the end wall portion 15 is recessed so as to be positioned further outward in the longitudinal direction of the first housing 11 than the end wall base inner side surface 15h, the inner convex surface 15c1 is also formed by the end wall base inner side surface 15h. It is recessed so as to be positioned further outward in the longitudinal direction of the first housing 11 .

The end face 14d of the extension end 14 and the inner side face 15h of the end wall base portion, which is the inner side face of the inner end portion 15g, are exposed side faces that are not covered with the first reinforcing metal fitting 51 on the side face of the first projecting end portion 18. include. Further, the upper surface 14a of the extension end portion 14 and the upper surface 15a of the end wall portion 15 are flat surfaces that are flush with each other. ).

After the left half body portion 10A and the right half body portion 10B are abutted, that is, the end wall portion 15 of the left half body portion 10A and the right half body portion 10B are separated so that the joint surfaces 15d are in contact with each other. After the end walls 15 are abutted, the first reinforcing metal fittings 51 are attached so as to cover and fix at least a part of the extended ends 14 and the end walls 15 on both sides, and the left half body 10A and It is combined with the right half body 10B.

The first reinforcing metal fitting 51 is a member integrally formed by stamping and bending a metal plate. It includes a pair of end wall clamping plates connected to both side edges and clamping the end wall portion 15, and a pair of extended end clamping plates connected to both ends of the upper plate and clamping the extended end portion 14. Specifically, the top plate includes an end wall upper surface covering portion 57 that covers the upper surface 15a of the end wall portion 15, and is connected to the left and right ends of the end wall upper surface covering portion 57 to cover the upper surface 14a of the extension end portion 14. and an extended end top cover 54 . The end wall clamping plate also includes an end wall outer surface covering portion 52 and an end wall inner surface covering portion 53 connected to the outer edge and inner edge of the end wall upper surface covering portion 57 . Further, the extension end clamping plate includes legs 55 connected to the outer ends of the extension end top cover 54 . A tail portion 56 is connected to the lower end of each leg portion 55 .

The end wall upper surface covering portion 57 is a strip-shaped member that extends in the width direction of the first connector 1 as a whole, and most of the upper surfaces 15a of the left and right end wall portions 15 where the connecting surfaces 15d are in contact with each other. is designed to cover the

The end wall outer surface covering portion 52 is a plate member that extends in the width direction and the vertical direction of the first connector 1 as a whole. connected to the outer edge. A lower curved portion 52b is formed in the vicinity of the lower end. As shown in FIGS. 5(c) and 6(c), when viewed from the width direction (Y-axis direction) of the first connector 1, the end wall outer surface covering portion 52 has an approximately S-shape and an upper curved portion. 52a and lower curved portion 52b are curved in opposite directions. In addition, the end wall outer surface covering portion 52 is formed so as to advance inward in the longitudinal direction of the first connector 1 as it goes downward as a whole, and the lower curved portion 52b is closer to the first connector 1 than the upper curved portion 52a. Located longitudinally inward. The lower end of the end wall outer surface covering portion 52 is inclined so as to face the longitudinal direction outside of the first connector 1 , that is, to be separated from the outer surface 15 b of the end wall portion 15 . In addition, the lower end of the end wall outer surface covering portion 52 is located above the lower surface of the tail portion 56 (on the Z-axis positive direction side) so as not to contact the surface of the first substrate. If necessary, the lower end of the end wall outer surface covering portion 52 may approach or abut on the surface of the first substrate. In this case, the connection strength of the first reinforcing metal fitting 51 to the first substrate is improved by connecting the lower end of the end wall outer surface covering portion 52 to the connection pad of the first substrate by soldering or the like.

The end wall inner surface covering portion 53 is a plate member extending in the width direction and the vertical direction of the first connector 1 as a whole. connected to the inner edge. A lower curved portion 53b is formed in the vicinity of the lower end. As shown in FIG. 6(c), when viewed from the width direction (Y-axis direction) of the first connector 1, the end wall inner surface covering portion 53 has a substantially S-shape, with an upper curved portion 53a and a lower curved portion. The portions 53b are curved in directions opposite to each other. In addition, the end wall inner surface covering portion 53 is formed so as to advance outward in the longitudinal direction of the first connector 1 as it goes downward as a whole, and the lower curved portion 53b is closer to the first connector 1 than the upper curved portion 52a. Located longitudinally outward. The lower end of the end wall inner surface covering portion 53 is inclined toward the inner side of the first connector 1 in the longitudinal direction, that is, away from the inner surface 15 c of the end wall portion 15 . In addition, the lower end of the end wall inner surface covering portion 53 is positioned above the lower surface of the tail portion 56 so as not to contact the surface of the first substrate. If necessary, the lower end of the end wall inner surface covering portion 53 can be made to approach or abut on the surface of the first substrate. In this case, the connection strength of the first reinforcing metal fitting 51 to the first substrate is improved by connecting the lower end of the end wall inner surface covering portion 53 to the connection pad of the first substrate by soldering or the like.

As shown in FIG. 6(c), in the first reinforcing bracket 51 before being attached to the first projecting end 18, the distance between the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 is The lower curved portion 52b of the covering portion 52 and the lower curved portion 53b of the end wall inner surface covering portion 53 are the narrowest. Specifically, the distance between the inner surface of the upper curved portion 52a of the end wall outer surface covering portion 52 and the inner surface of the upper curved portion 53a of the end wall inner surface covering portion 53 is L3, and the lower curved portion of the end wall outer surface covering portion 52 is Assuming that the distance between the inner surface of 52b and the inner surface of the lower curved portion 53b of the end wall inner surface covering portion 53 is L4, L3≧L4 (preferably L3>L4). Assuming that the thicknesses (dimensions in the X-axis direction) of the thick portion 15e and the thin portion 15f of the end wall portion 15 are l3 and l4, respectively, L3≧l3 (preferably L3>l3). It has become. L4<l3 before the first reinforcing metal fitting 51 is attached to the first projecting end 18, and L4>l4 after the attachment.

Due to this relationship, when the first reinforcing metal fitting 51 is attached to the first protruding end portion 18, the inner surface 52c of the end wall outer surface covering portion 52 and the inner surface 53c of the end wall inner surface covering portion 53 abut against each other. The thick part 15e is securely sandwiched. In particular, when L3>l3, the inner surface 52c of the end wall outer surface covering portion 52 and the inner surface 53c of the end wall inner surface covering portion 53 are the outer convex lower edge 15b3 and the inner convex lower edge 15c3 (lower edge of the thick portion 15e). See FIG. 8). This prevents the first reinforcing metal fitting 51 from coming off the first projecting end portion 18 .

Further, the extension end upper surface covering portion 54 covers most of the upper surfaces 14a of the left and right extension end portions 14 .

The leg portion 55 is a belt-shaped member that extends in the vertical direction of the first connector 1, and is connected to the outer end of the extended end top cover portion 54 by an upper curved portion 55a formed at the upper end. A lower curved portion 55b is formed at the lower end. As shown in FIGS. 5(a) and 5(b), etc., the leg 55 has an approximately S-shape when viewed from the longitudinal direction (X-axis direction) of the first connector 1, with an upper curved portion 55a and a lower curved portion 55a. It curves in the opposite direction to the side curved portion 55b. Further, the leg portion 55 is inclined so as to advance inward in the width direction of the first connector 1 as it goes downward as a whole, and the lower curved portion 55b is located furthest inward in the width direction of the first connector 1 .

As shown in FIG. 6(b), in the first reinforcing metal fitting 51 before being attached to the first protruding end 18, the interval between the left and right leg portions 55 is the narrowest at the lower curved portion 55b. Specifically, when the interval between the inner surfaces of the left and right upper curved portions 55a is L1, and the interval between the inner surfaces of the left and right lower curved portions 55b is L2, then L1≧L2 (preferably L1>L2). there is Assuming that the distance between the outer convex surfaces 14b1 and the distance between the outer concave surfaces 14b2 of the left and right extended ends 14 in the first protruding end 18 is l1 and l2, respectively, as will be described later, L1≧l1 (preferably L1> l1). L2<l1 before the first reinforcing metal fitting 51 is attached to the first projecting end 18, and L2>l2 after the attachment.

Due to this relationship, when the first reinforcing metal fitting 51 is attached to the first projecting end portion 18, the inner surfaces 55c of the left and right leg portions 55 securely sandwich the thick portion 14e of the extended end portion 14 between them. In particular, when L1>l1, the inner surface 55c of the leg portion 55 sandwiches and presses the lower edge 14b3 (see FIG. 8) of the outer convex surface, which is the lower edge of the thick portion 14e. This prevents the first reinforcing metal fitting 51 from coming off the first projecting end portion 18 .

The tail portion 56 is connected to the tip of the lower curved portion 55b of the leg portion 55 and extends outward in the width direction of the first connector 1 . Specifically, the tail portion 56 extends outward in the width direction from the outer surface 14b of the extension end portion 14 and is connected and fixed to a connection pad (not shown) exposed on the surface of the first substrate by soldering or the like. It should be noted that the connection pads can be coupled to conductive traces, for example power lines.

Next, a method of configuring the first connector 1 by connecting the left half body portion 10A and the right half body portion 10B with the first reinforcing metal fitting 51 will be described.

When constructing the first connector 1, the operator first brings the left half body 10A and the right half body 10B together as shown in FIG. That is, the end wall portion 15 of the left half body portion 10A and the end wall portion 15 of the right half body portion 10B are brought into contact with each other, and the connecting surface 15d at the tip of the end wall portion 15 of the left half body portion 10A and the right half body portion The connecting surface 15d at the tip of the end wall portion 15 of 10A is brought into contact. Thereby, the first projecting end portion 18 is configured.

Subsequently, as shown in FIG. 9, the operator positions the first reinforcing metal fitting 51 above the configured first protruding end 18 and moves the first reinforcing metal fitting 51 relative to the first protruding end. 18, and attach the first reinforcing metal fittings 51 so as to cover at least a part of the extended end portions 14 and the end wall portions 15 on both sides. In this case, the end wall upper surface covering portion 57 faces the upper surfaces 15a of the left and right end wall portions 15 with which the connecting surfaces 15d are in contact with each other, and the extension end upper surface covering portions 54 face the upper surfaces 14a of the left and right extension end portions 14. The end wall outer surface covering portion 52 faces the outer surface 15b of the end wall portion 15, the end wall inner surface covering portion 53 faces the inner surface 15c of the end wall portion 15, and the leg portion 55 extends from the extension end portion. The posture of the first reinforcing metal fitting 51 is controlled so as to face the outer surface 14b of 14 .

As described above, in the first reinforcing metal fitting 51 before being attached to the first protruding end 18 , the distance between the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 is the lower side of the end wall outer surface covering portion 52 . The curved portion 52b and the lower curved portion 53b of the end wall inner surface covering portion 53 are the narrowest. Specifically, the distance between the inner surface of the upper curved portion 52a of the end wall outer surface covering portion 52 and the inner surface of the upper curved portion 53a of the end wall inner surface covering portion 53 is L3, and the lower curved portion of the end wall outer surface covering portion 52 is Assuming that the distance between the inner surface of 52b and the inner surface of the lower curved portion 53b of the end wall inner surface covering portion 53 is L4, L3≧L4 (preferably L3>L4). Further, when the thicknesses (dimensions in the X-axis direction) of the thick portion 15e and the thin portion 15f of the end wall portion 15 are l3 and l4 respectively, L3≧l3 (preferably L3>l3). L4<l3 before the first reinforcing metal fitting 51 is attached to the first projecting end 18, and L4>l4 after the attachment.

Furthermore, the interval between the left and right leg portions 55 is the narrowest at the lower curved portion 55b. Specifically, when the interval between the inner surfaces of the left and right upper curved portions 55a is L1, and the interval between the inner surfaces of the left and right lower curved portions 55b is L2, then L1≧L2 (preferably L1>L2). there is Further, when the distances between the outer convex surfaces 14b1 and the outer concave surfaces 14b2 of the left and right extended ends 14 of the first protruding end 18 are l1 and l2, respectively, L1≧l1 (preferably L1>l1). L2<l1 before the first reinforcing metal fitting 51 is attached to the first projecting end 18, and L2>l2 after the attachment.

Therefore, when the first reinforcing metal fitting 51 is lowered relative to the first protruding end portion 18 and attached, the end wall portion 15 widens the gap between the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 . The end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 are elastically deformed. Moreover, the space between the left and right leg portions 55 is widened by the extension end portion 14, and the left and right leg portions 55 are elastically deformed.

Then, as shown in FIGS. 1 and 2, the attachment of the first reinforcing metal fitting 51 to the first projecting end portion 18 is completed, and the left half body portion 10A and the right half body portion 10B are separated by the first reinforcing metal fitting 51. When coupled, the end wall portion 15 is tightened from the front and rear by the springiness exerted by the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53, and is extended by the springiness exerted by the left and right leg portions 55. The ends 14 are tightened from the left and right. Therefore, the end wall portion 15 is tightened from the front, rear, left, and right by the first reinforcing metal fitting 51, and the connecting surfaces 15d that are in contact with each other are brought into close contact with each other and integrated. As a result, the left half body portion 10A and the right half body portion 10B are joined by the first reinforcing metal fitting 51, and the first connector 1 is constructed.

In addition, the lower curved portion 52b of the end wall outer surface covering portion 52 and the lower curved portion 53b of the end wall inner surface covering portion 53, which are narrower than the interval between the outer convex surface 15b1 and the inner convex surface 15c1, form the outer convex surface 15b1 and the inner convex surface 15c1. Since it is positioned below the inner convex surface 15c1, when the first reinforcing bracket 51 is lifted relatively to the end wall portion 15 and removed, the step between the outer convex surface 15b1 and the outer concave surface 15b2 and the inner convex surface 15c1 The lower curved portion 52b of the end wall outer surface covering portion 52 and the lower curved portion 53b of the end wall inner surface covering portion 53 are caught in the step between the inner concave surface 15c2, making removal difficult. That is, the function of preventing the first reinforcing metal fitting 51 from coming off is exhibited.

Similarly, since the lower curved portions 55b of the left and right leg portions 55, which are closer to each other than the interval between the left and right outer convex surfaces 14b1, are positioned below the outer convex surfaces 14b1, the first reinforcing metal fittings 51 are positioned relatively to each other. When lifted from the end wall portion 15 and removed, the lower curved portion 55b of the leg portion 55 is caught in the step between the outer convex surface 14b1 and the outer concave surface 14b2, making removal difficult. That is, the function of preventing the first reinforcing metal fitting 51 from coming off is exhibited.

In addition, the distance between the end wall outer surface covering portion 52 near the upper curved portion 52a and the end wall inner surface covering portion 53 near the upper curved portion 53a is narrower than the distance between the outer convex surface 15b1 and the inner convex surface 15c1. As a result, the thick portion 15e of the end wall portion 15 is sandwiched from both sides by the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53, so that the end wall portion 15 and the right half portion 10A of the left half portion 10A are sandwiched. It is firmly coupled with the end wall portion 15 of 10B.

Similarly, if the distance between the portions of the left and right leg portions 55 near the upper curved portion 55a is narrower than the distance between the outer convex surfaces 14b1 of the left and right extension ends 14, the thick portions of the extension ends 14 Since 14e is sandwiched by the legs 55 from both sides, the end wall portion 15 of the left half body portion 10A and the end wall portion 15 of the right half body portion 10B are firmly coupled.

Furthermore, if the distance between the lower curved portion 52b of the end wall outer surface covering portion 52 and the lower curved portion 53b of the end wall inner surface covering portion 53 is narrower than the distance between the outer concave surface 15b2 and the inner concave surface 15c2, Since the thin portion 15f of the end wall portion 15 is sandwiched from both sides by the lower curved portion 52b of the end wall outer surface covering portion 52 and the lower curved portion 53b of the end wall inner surface covering portion 53, the end wall of the left half body portion 10A is The portion 15 and the end wall portion 15 of the right half body portion 10B are joined more firmly.

Similarly, if the space between the lower curved portions 55b of the left and right leg portions 55 is narrower than the space between the outer concave surfaces 14b2 of the left and right extension ends 14, the thin portions 14f of the extension ends 14 will not be the legs. Since they are sandwiched from both sides by the lower curved portions 55b of the portion 55, the end wall portion 15 of the left half body portion 10A and the end wall portion 15 of the right half body portion 10B are joined more firmly.

Further, in a state where the attachment of the first reinforcing metal fitting 51 to the first projecting end portion 18 is completed, the upper surface 14a of the extension end portion 14 and the upper surface 15a of the end wall portion 15 are the upper surface of the first convex portion 12. Since they are recessed so as to be located below the fitting surface 12a, the upper surfaces of the end wall upper surface covering portion 57 and the extension end upper surface covering portion 54 are flush with or flush with the fitting surface 12a. It is recessed further down. That is, the upper surfaces of the end wall upper surface covering portion 57 and the extension end upper surface covering portion 54 do not protrude from the fitting surface 12a.

Furthermore, since the entire outer surface 14b of the extension end 14 is recessed so as to be positioned more inward in the width direction of the first connector 1 than the outer surface 12b of the first projection 12, the outer surface of the leg 55 is , flush with the outer surface 12b or recessed inward in the width direction of the first connector 1 from the outer surface 12b. That is, the outer surface of the leg portion 55 does not protrude from the outer surface 12b.

Furthermore, since the entire outer surface 15b of the end wall portion 15 is recessed so as to be positioned inward in the longitudinal direction of the first connector 1 from the end surface 14d of the extended end portion 14, the outer surface of the end wall outer surface covering portion 52 is is flush with the end face 14d or recessed inward in the longitudinal direction of the first connector 1 from the end face 14d. That is, the outer surface of the end wall outer surface covering portion 52 does not protrude from the end surface 14d.

Furthermore, since the entire inner surface 15c of the end wall portion 15 is recessed so as to be located outside the end wall base inner surface 15h in the longitudinal direction of the first connector 1, the outer surface of the end wall inner surface covering portion 53 is , is flush with the inner side surface 15h of the end wall base or is recessed outward in the longitudinal direction of the first connector 1 from the inner side surface 15h of the end wall base. That is, the outer surface of the end wall inner surface covering portion 53 does not protrude from the end wall base inner surface 15h.

The tail portion 56 connected to the tip of the lower curved portion 55b of the leg portion 55 protrudes outward in the width direction of the first connector 1 from the outer surface 12b of the first protrusion 12. As shown in FIG. The bottom surface of the tail portion 56 is substantially flush with the bottom surface of the tail portion 62 of the first terminal 61 attached to the first projection 12 and the mounting surface 17 a of the first housing 11 .

Also, the lower ends of the end wall outer surface covering portion 52 and the lower ends of the end wall inner surface covering portion 53 are positioned above the lower surface of the tail portion 56 , and therefore positioned above the mounting surface 17 a of the first housing 11 . Therefore, the lower end of the end wall outer surface covering portion 52 and the lower end of the end wall inner surface covering portion 53 do not contact the surface of the first substrate.

Next, the configuration of the second connector 101 will be described.

11 is a perspective view of the second connector in the first embodiment, and FIG. 12 is an exploded view of the second connector in the first embodiment.

The second connector 101 as a mating connector in this embodiment has a second housing 111 as a mating connector main body integrally formed of an insulating material such as synthetic resin. As shown in the figure, the second housing 111 has a substantially rectangular thick plate shape that is a substantially rectangular parallelepiped. On the side of the second housing 111 into which the first connector 1 is fitted, that is, on the side of the fitting surface 111a (positive direction of the Z axis), there is a substantially rectangular recess 112 surrounded by the first connector. A recess 112 is formed to fit with the housing 11 . A second convex portion 113 is formed integrally with the second housing 111 in the concave portion 112 as an island portion to be fitted with the concave groove portion 13 . A side wall portion 114 extending parallel to the two convex portions 113 is formed integrally with the second housing 111 .

The second convex portion 113 and the side wall portion 114 protrude upward (in the positive Z-axis direction) from the bottom surface of the concave portion 112 and extend in the longitudinal direction of the second connector 101 . As a result, on both sides of the second protrusion 113, as a part of the recess 112, recessed grooves 112a, which are elongated recesses extending in the longitudinal direction (X-axis direction) of the second connector 101, are formed.

Both side surfaces of the second protrusion 113 and inner side surfaces of the side wall portion 114 are formed with second terminal receiving groove cavities 115a in the form of concave grooves. In addition, a hole-shaped second terminal receiving hole cavity 115b is formed in the second convex portion 113 and the side wall portion 114. As shown in FIG. Since the second terminal receiving groove cavity 115a and the second terminal receiving hole cavity 115b are connected and integrated with each other at the bottom surface of the concave groove portion 112a, the second terminal receiving groove cavity 115a and the second terminal receiving hole cavity 115b will be collectively described as the second terminal receiving cavity 115. FIG. The second terminal accommodating cavities 115 are arranged at a pitch corresponding to the first terminals 61 and in a corresponding number.

The second terminal 161 is a member integrally formed by punching a conductive metal plate, and includes a main body portion 163 and a tail portion 162 connected to the lower end of the main body portion 163 . , a connection portion 164 extending in the width direction (Y-axis direction) of the second connector 101 from the vicinity of the lower end of the main body portion 163, and a contact portion extending upward (Z-axis positive direction) from the connection portion 164. 165. It is desirable that a contact protrusion 165 a protruding toward the main body portion 163 is formed near the tip of the contact portion 165 .

The body portion 163 is a portion that is press-fitted and held in the second terminal receiving hole cavity 115b. The tail part 162 is bent and connected to the lower end of the main body part 163, extends in the width direction of the second housing 111, and is connected to the connection pads connected to the conductive traces of the second substrate by soldering or the like. be. Note that the conductive traces are typically signal lines. Further, the contact portion 165 is a portion that contacts the first terminal 61 of the first connector 1 when the first connector 1 and the second connector 101 are fitted together. It engages with the contact recess 65 a formed in the contact portion 65 of the 1 terminal 61 .

The second terminal 161 is attached to the second housing 111 by being inserted into the second terminal receiving cavity 115 from below the second housing 111 . As a result, the body portion 163 of the second terminal 161 is press-fitted and held in the second terminal receiving hole cavity 115b, and the contact portion 165 is received in the second terminal receiving groove cavity 115a and exposed to the concave groove portion 112a. The bottom surface of the tail portion 162 is exposed on the mounting surface 111 b as the bottom surface of the second housing 111 .

In addition, the second terminals 161 attached to the grooves 112a are oriented such that adjacent terminals are opposite to each other with respect to the width direction of the grooves 112a, similarly to the first terminals 61. . In the example shown in FIG. 12, the posture of the second terminal 161 positioned at the front end (X-axis positive direction end) among the second terminals 161 attached to the concave groove portion 112a on the Y-axis positive direction side is such that the tail portion 162 is positioned in the Y direction. The second terminal 161 located second from the front end is oriented so that the tail portion 62 projects in the positive direction of the Y-axis. Oriented. In this way, the second terminals 161 are arranged alternately in opposite directions and attached to the recessed groove portion 112a. It is twice the pitch of the two terminals 161 . Therefore, connection work such as soldering to the connection pads of the second substrate can be easily performed. Also, the pitch of the contact portions 165 exposed in the concave groove portion 112 a is twice the pitch of the second terminals 161 .

Second projecting end portions 121 as fitting guide portions are provided at both ends of the second housing 111 in the longitudinal direction. A fitting recess 122 is formed as a part of the recess 112 in each second protruding end 121 . The fitting recess 122 is a substantially rectangular recess and is connected to both longitudinal ends of each recess 112a. Into the fitting recess 122, the first projecting end 18 of the first connector 1 is inserted while the first connector 1 and the second connector 101 are fitted together. In addition, the second protruding end portion 121 has a reinforcing metal fitting receiving recess 126 . A second reinforcing metal fitting 151 as a mating reinforcing metal fitting is accommodated in the reinforcing metal fitting accommodating concave portion 126 and attached to the second projecting end portion 121 .

The second reinforcing metal fitting 151 is a member integrally formed by stamping and bending a metal plate. A center covering portion 157 connected to the upper end of the second main body portion 152, side covering portions 153 connected to both left and right ends of the second main body portion 152, and one side edge of the side covering portion 153 connected to the side covering portion 153. and a tail portion 156 connected to the lower end of the second body portion 152 . The tail portion 156 extends outward in the longitudinal direction of the second connector 101 and is connected and fixed to connection pads (not shown) exposed on the surface of the second substrate by soldering or the like. It should be noted that the connection pads are preferably coupled to conductive traces, for example power lines.

Next, the operation of fitting the first connector 1 and the second connector 101 configured as described above will be described.

Here, in the first connector 1, the tail portion 62 of the first terminal 61 is connected to a connection pad connected to a conductive trace of the first substrate (not shown) by soldering or the like, and the tail portion of the first reinforcing metal fitting 51 is connected to the connection pad. It is assumed to be surface mounted to the first substrate by soldering or otherwise connecting 56 to connection pads coupled to conductive traces on the first substrate. The conductive trace connected to the connection pad to which the tail portion 62 of the first terminal 61 is connected is a signal line, and is connected to the connection pad to which the tail portion 56 of the first reinforcing metal fitting 51 is connected. It is assumed that the conductive traces are power lines.

Similarly, in the second connector 101, the tail portions 162 of the second terminals 161 are connected by soldering or the like to connection pads connected to the conductive traces of the second substrate (not shown), and the tail portions of the second reinforcing metal fittings 151 are connected to each other. 156 is surface mounted to the second substrate by being connected, such as by soldering, to connection pads coupled to conductive traces on the second substrate. 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. Conductive traces are assumed to be power lines.

First, the operator causes the fitting surface 12a of the first protrusion 12 as the fitting surface of the first housing 11 of the first connector 1 to face the fitting surface 111a of the second housing 111 of the second connector 101. , the position of the first projection 12 of the first connector 1 matches the position of the corresponding concave groove 112a of the second connector 101, and the position of the first projecting end 18 of the first connector 1 matches the position of the second connector 101. , the alignment of 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 are moved in the direction of approaching the mating side, that is, in the mating direction, the first convex portion 12 and the first protruding end portion 18 of the first connector 1 are moved. is inserted into the concave groove portion 112 a and the fitting concave portion 122 of the second connector 101 . Thereby, the fitting between the first connector 1 and the second connector 101 is completed. Then, the first terminal 61 and the second terminal 161 are brought into conduction.

Thus, in the present embodiment, the first connector 1 has a pair of left and right half parts 10A each including the first housing 11 and the plurality of first terminals 61 attached to the first housing 11. and the right half body portion 10B and the first housings 11 of the left half body portion 10A and the right half body portion 10B are attached to the first protruding end portions 18 formed at both ends of the first housing 11 by abutting each other. Each of the first housings 11 includes a first reinforcing metal fitting 51 that joins the half body portion 10A and the right half body portion 10B, and each of the first housings 11 extends in its longitudinal direction and has a first convex portion 12 that holds a first terminal 61. , an extended end portion 14 connected to both longitudinal ends of the first convex portion 12, and an end wall portion 15 extending from the extended end portion 14 toward the other half body portion, the first protruding end portion Each of 18 includes left and right end walls 15 abutting each other and left and right extension ends 14 from which the end walls 15 extend.

As a result, the distance between the first housings 11 to which the plurality of first terminals 61 are attached can be narrowed, and the size of the first connector 1 can be reduced. Moreover, the manufacturing of the first connector 1 is facilitated, and the reliability of the first connector 1 is improved.

The first reinforcing metal fitting 51 is connected to the end wall upper surface covering portion 57 and the extended end upper surface covering portion 54 as the upper plate extending in the width direction of the first housing 11 and to both side edges of the upper plate. An end wall outer surface covering portion 52 and an end wall inner surface covering portion 53 as a pair of end wall sandwiching plates for sandwiching the portion 15, and a pair of extended end sandwiching plates connected to both ends of the upper plate and sandwiching the extended end portion 14. The end wall upper surface covering portion 57 faces the upper surface 15a of the end wall portion 15, and the extended end upper surface covering portion 54 is connected to both ends of the end wall upper surface covering portion 57 to form an extended end portion. 14, the end wall outer surface covering portion 52 faces the outer surface 15b of the end wall portion 15, the end wall inner surface covering portion 53 faces the inner surface 15c of the end wall portion 15, and the leg portion 55 , is connected to the outer end of the extension end top cover 54 and faces the outer surface 14b of the extension end 14. As shown in FIG. As a result, the end wall portion 15 of the left half body portion 10A and the end wall portion 15 of the right half body portion 10B are firmly coupled to reliably form the first projecting end portion 18, and the left half body portion 10A and the right half body portion 10A The half body portion 10B is reliably coupled.

Further, the upper surface 15a of the end wall portion 15 and the upper surface 14a of the extension end portion 14 are recessed from the fitting surface 12a of the first convex portion 12, and the outer surface 15b of the end wall portion 15 is recessed from the end surface 14d of the extension end portion 14. The inner surface 15c of the end wall portion 15 is recessed from the inner surface 15h of the end wall base portion, the outer surface 14b of the extension end portion 14 is recessed from the outer surface 12b of the first projection 12, and the end wall upper surface is recessed. The covering portion 57 and the extended end upper surface covering portion 54 do not protrude from the fitting surface 12 a of the first convex portion 12 , and the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 serve as exposed side surfaces of the first projecting end portion 18 . The leg portion 55 does not protrude from the outer side surface 12b of the first convex portion 12, and does not protrude from the end surface 14d of the first protrusion 12 and the inner side surface 15h of the end wall base portion. Therefore, the surface of the first reinforcing metal fitting 51 does not protrude from the surface of the first housing 11 .

Further, the end wall portion 15 includes a thick portion 15e and a thin portion 15f connected to the lower side of the thick portion 15e, and the extension end portion 14 extends between the thick portion 14e and the thick portion 14e. The lower curved portion of the end wall outer surface covering portion 52 as the closest portion between the end wall clamping plates in the first reinforcing fitting 51 before being attached to the first protruding end portion 18, including the connected thin portion 14f. The interval between 52b and the lower curved portion 53b of the end wall inner surface covering portion 53 is narrower than the interval between the outer surface 15b and the inner surface 15c of the end wall portion 15 corresponding to the thick portion 15e. The interval between the lower curved portions 55b of the left and right leg portions 55, which are the closest portions, is narrower than the interval between the outer side surfaces 14b of the portions corresponding to the thick portions 14e of the extended end portion 14. As shown in FIG. As a result, when the first reinforcing metal fitting 51 is attached to the first projecting end portion 18, the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 are pushed apart, and the left and right leg portions 55 are pushed. Therefore, when the attachment of the first reinforcing metal fitting 51 to the first protruding end portion 18 is completed, the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 exert spring properties to move the end wall portion 15 back and forth. The left and right leg portions 55 exhibit springiness to tighten the extended end portion 14 from the left and right. Therefore, the end wall portion 15 is tightened from the front, back, left and right by the first reinforcing metal fittings 51, and the connecting surfaces 15d that are in contact with each other are brought into close contact with each other and integrated, so that the first protruding end portion 18 can be reliably secured. Configured.

Further, the outer surface 15b of the end wall portion 15 includes a step between the outer convex surface 15b1 corresponding to the thick portion 15e and the outer concave surface 15b2 corresponding to the thin portion 15f, and the inner surface 15c of the end wall portion 15 is The outer surface 14b of the extension end 14 includes a step between the inner convex surface 15c1 corresponding to the thick portion 15e and the inner concave surface 15c2 corresponding to the thin portion 15f, and the outer surface 14b of the extension end portion 14 is formed between the outer convex surface 14b1 corresponding to the thick portion 14e and the thin portion. It includes a step between the outer concave surface 14b2 corresponding to the portion 14f. As a result, even if an upward external force is applied to the first reinforcing metal fitting 51 attached to the first projecting end portion 18, the lower curved portion 52b of the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 will not move. The lower curved portion 53b of the leg portion 55 and the lower curved portion 55b of the leg portion 55 are caught on the step, making it difficult to remove the first reinforcing metal fitting 51 . Therefore, the first reinforcing metal fitting 51 is reliably prevented from coming off.

Next, a second embodiment will be described. It should be noted that components having the same structure as in the first embodiment are given the same reference numerals, and descriptions thereof are omitted. Further, descriptions of the same operations and effects as those of the first embodiment will be omitted.

FIG. 13 is a perspective view of the first reinforcing metal fitting in the second embodiment, FIG. 14 is a first three-sided view of the first reinforcing metal fitting in the second embodiment, and FIG. 1 is a second trihedral view of the reinforcing metal fitting. 14, (a) is a front view, (b) is a rear view, and (c) is a side view. In FIG. 15, (a) is a top view, and (b) is a G- A cross-sectional view taken along the line G, and (c) is a cross-sectional view taken along the line HH in (a).

The first reinforcing metal fitting 51 in this embodiment includes hemispherical projections 58 as locking projections formed on the end wall outer surface covering portion 52 , the end wall inner surface covering portion 53 and the leg portion 55 . The projection 58 forms a step between the outer convex surface 15b1 and the outer concave surface 15b2 of the end wall portion 15 and the inner convex surface 15c1 and the inner concave surface when the attachment of the first reinforcing metal fitting 51 to the first protruding end portion 18 is completed. 15c2 and between the outer convex surface 14b1 and the outer concave surface 14b2 of the extension end 14. Therefore, when the first reinforcing metal fitting 51 is lifted relative to the end wall portion 15 to be removed, the protrusion 58 is engaged with the step, making removal difficult. That is, the function of preventing the first reinforcing metal fitting 51 from coming off is exhibited.

The projection 58 is a portion formed by bulging a part of the metal plate forming the end wall outer surface covering portion 52, the end wall inner surface covering portion 53 and the leg portion 55 by performing processing such as pressing. , the outer surface covering portion 52 of the end wall, the inner surface covering portion 53 of the end wall, and the inner surface of the leg portion 55, so as to protrude in a hemispherical shape. On the outer surfaces of the end wall outer surface covering portion 52, the end wall inner surface covering portion 53, and the leg portion 55, as a result of forming the projections 58 by swelling the metal plate, recesses are formed at positions corresponding to the respective projections 58. 58a is formed.

The protrusion 58 is formed at least one of each of the end wall outer surface covering portion 52, the end wall inner surface covering portion 53, and the leg portion 55, but may be formed at two or more locations as necessary. may The position of the protrusion 58 in the vertical direction (Z-axis direction) is such that the upper surface 58b of the protrusion 58 comes into contact with the step when the first reinforcing metal fitting 51 is completely attached to the first projecting end portion 18. It is desirable to be in such a position.

Thus, in this embodiment, the first reinforcing metal fitting 51 is the projection 58 formed on the end wall outer surface covering portion 52, the end wall inner surface covering portion 53, and the leg portion 55, and is a projection that engages with the step. 58 included. As a result, even if an upward external force is applied to the first reinforcing metal fitting 51 attached to the first protruding end portion 18, the projection 58 will remain in contact with the outer surface 15b and the inner surface 15c of the end wall portion 15, as well as the extension. Since it engages with the step included in the outer surface 14b of the end portion 14, it becomes more difficult to remove the first reinforcing metal fitting 51. As shown in FIG. Therefore, the first reinforcing metal fitting 51 is more reliably prevented from coming off.
