Description

TECHNICAL FIELD This disclosure relates to connectors.

Conventionally, connectors such as board-to-board connectors have been used to electrically connect a pair of parallel circuit boards. Such connectors are attached to each of the mutually opposing surfaces of a pair of circuit boards, and are fitted together to establish electrical conduction (for example, see Patent Document 1).

FIG. 16 is a perspective view showing a conventional connector.

In the figure, 811 is a connector housing mounted on a circuit board (not shown), and has a pair of elongated protrusions 812 extending in the longitudinal direction. A plurality of terminals 861 are attached to the convex portion 812 in line with each other in the longitudinal direction of the connector.

Then, when the connector is fitted with a mating connector (not shown), the convex portions 812 are inserted into each of a pair of grooves formed in the mating housing of the mating connector. As a result, the terminal 861 contacts and conducts with each of the mating terminals (not shown) installed in line in the groove.

However, in the conventional connector, the terminals 861 are formed to be integrated with the housing 811, so when miniaturized, the distance between the protrusions 812 becomes narrower, and the pitch of the terminals 861 becomes narrower. , manufacturing becomes difficult. Usually, the terminal 861 is integrated with a pair of protrusions 812 of the housing 811 by a molding method called over-molding or insert molding, so that the interval between the protrusions 812 becomes narrower and the pitch of the terminal 861 becomes smaller. When the number of terminals 861 becomes narrower, it becomes difficult to arrange a large number of terminals 861 accurately in the positions corresponding to the pair of protrusions 812 in the molding die of the housing 811.

Here, we have solved the problems of the conventional connectors mentioned above, and created a connector that is easy to manufacture, can be miniaturized, and has high reliability by narrowing the distance between the protrusions to which multiple terminals are attached. The purpose is to provide

The directions are opposite to each other, and the upper portions of adjacent convex portions are arranged so as to overlap when viewed from the longitudinal direction of the convex portion.

In another connector, each of the terminals further includes a tail portion that protrudes outward in the width direction of the connector body and is connected to the board, and the tail portions of adjacent terminals are different from each other in the connector body. are arranged so as to protrude in opposite directions with respect to the width direction.

In still another connector, each of the connector bodies includes a bottom plate portion extending in the longitudinal direction thereof, the convex portion is integrally formed on the upper surface of the bottom plate portion, and the tail portion is formed on the bottom plate portion. The connector body protrudes outward from the connector body in the width direction.

In still another connector, the space between the left and right halves is an elongated groove extending in the longitudinal direction of the connector, and the groove opens on the top and bottom surfaces of the connector. .

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 mount type connector mounted on the surface of a first board, which is a board (not shown) as a mounting member, and is mated with a second connector 101 as a mating connector, which will be described later. Ru. Further, 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, which is a board (not shown) serving as a mounting member.

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

Furthermore, in this embodiment, expressions indicating directions such as top, bottom, 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 as follows: It is not an absolute thing but a relative thing, 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 will change. It should be interpreted and modified according to changes.

The first connector 1 is constructed by joining a pair of left and right halves, that is, a left half 10A and a right half 10B, with a first reinforcing metal fitting 51 as a reinforcing metal fitting. . In addition, since the left half body part 10A and the right half body part 10B are the same member arranged so as to face each other in the left and right directions, they will be described as the half body part 10 in the case of an integrated description. The left half body part 10A and the right half body part 10B each have a portal shape in plan view (shape projected on the XY plane), and the left half body part 10A and the right half body part 10B are connected to each other. 10B is an elongated groove portion 13 extending in the longitudinal direction (X-axis direction) of the first connector 1. The groove portion 13 is a through hole opened on the upper and lower surfaces of the first connector 1 .

The half body 10 is integrally formed of an insulating material such as a synthetic resin, and has a first housing 11 serving as a connector body having a gate-shaped shape in plan view. Each first housing 11 includes an elongated strip-shaped bottom plate portion 17 extending in the longitudinal direction (X-axis direction) of the first housing 11, and a bottom plate portion 17 of the first housing 11 integrally formed on the upper surface of the bottom plate portion 17. It includes a first convex portion 12 as an elongated convex portion extending in the longitudinal direction. The first convex portion 12 is a member whose cross section is shaped like an upside-down U-shape, and has a curved fitting surface 12a located on the upper side (positive side of the Z-axis) and the fitting surface 12a. It has an outer surface 12b and an inner surface 12c connected to both left and right sides of the surface 12a. The outer surface 12b and the inner surface 12c are a pair of parallel and opposing planes that extend in the longitudinal direction of the first housing 11. In addition, since the dimension of the first convex part 12 in the width direction (Y-axis direction) is shorter than the dimension of the bottom plate part 17 in the width direction, the bottom plate part 17 protrudes outward in the width direction from the outer surface 12b and the inner surface 12c. Further, the 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 serving as a terminal is disposed on each first convex portion 12 . A plurality of first terminals 61 (26 in the example shown in the figure) are arranged at a predetermined pitch. The first terminal 61 is a member integrally formed by processing a conductive metal plate by punching, bending, etc., and includes a main body portion 63 extending in the width direction of the first convex portion 12; a tail portion 62 connected to one end of the main body portion 63; a contact portion 65 extending in the vertical direction bent approximately 90 degrees and connected to the other end of the main body portion 63; The upper end portion 64 is bent at 90 degrees and connected to the upper end portion 64 .

The main body portion 63 is a portion embedded and held in the bottom plate portion 17. Further, 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 a connection pad connected to a conductive trace on the first substrate. Note that the conductive trace is typically a signal line. Further, the contact portion 65 is a portion that comes into contact with a second terminal 161 provided in the second connector 101 and will be described later when the first connector 1 and the second connector 101 are fitted, and is preferably recessed from the surface. It includes a contact recess 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 cavity of a mold in which the first terminal 61 is set in advance. As a result, in the first terminal 61, the lower surfaces of the main body portion 63 and the tail portion 62 are exposed to the mounting surface 17a of the bottom plate portion 17, and the surfaces of the contact portion 65 and the upper end portion 64 are exposed to the outer surface 12b of the first convex portion 12 or It is integrally attached to the first housing 11 with the inner surface 12c and the fitting surface 12a exposed.

Further, the first terminals 61 attached to each of the first protrusions 12 are oriented such that the positions of adjacent terminals are opposite to each other with respect to the width direction of the first protrusions 12 . In the example shown in FIG. 4, the attitude of the first terminal 61 located at the front end (X-axis positive direction end) of the first terminals 61 attached to the first convex portion 12 of the left half body portion 10A is is oriented so that the tail part 62 protrudes outward (Y-axis positive direction side), whereas the first terminal 61 located second from the front end has a tail part 62 directed inwards (Y-axis negative direction side). It is oriented so that it protrudes toward the In this way, the first terminals 61 are attached to the first convex portion 12 in such a way that they are alternately arranged in opposite directions, so that the pitch of the tail portions 62 protruding from each side of the first convex portion 12 is , is twice the pitch of the first terminals 61. Therefore, connection work such as soldering to the connection pads on the first substrate can be easily performed. Further, the pitch of the contact portions 65 exposed on the outer surface 12b of the first convex portion 12 and the pitch of the contact portions 65 exposed on the inner surface 12c are also twice the pitch of the first terminals 61.

Note that the first terminal 61 is a member that is integrated with the first housing 11 by a molding method called over molding or insert molding, so it does not exist apart from the first housing 11. For convenience of explanation, it should be noted that in FIG. 4, it is drawn as if it is spaced apart from the first housing 11.

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

Further, the first protruding end portion 18 is constituted by the extended end portions 14 and the end wall portions 15 of the left and right half portions 10. Extended end portions 14 extending in the longitudinal direction are integrally connected to both longitudinal ends of the first convex portion 12 of each half body portion 10, and each extended end portion 14 has a width corresponding to the width of the first convex portion 12. The end wall portions 15 extending in the direction are each integrally connected. Note that the end wall portion 15 in the left half body portion 10A extends toward the right direction (Y-axis negative direction), and the end wall portion 15 in the right half body portion 10B extends toward the left direction (Y-axis positive direction). It is extending. In each of the half-body parts 10 arranged so as to face each other in the left and right directions, the end wall part 15 extends toward the other half-body part 10 . The end surface of the end wall portion 15 that faces the other half portion 10 functions as a coupling surface 15d.

Each extension end 14 is connected to a thick wall portion 14e that is wide, that is, thick (large in dimension in the Y-axis direction), and to the lower side of the thick wall portion 14e (on the negative side of the Z-axis direction). , and a thinner portion 14f (having a 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) than the outer convex surface 14b1. Since the entire outer surface 14b of the extended end portion 14 is recessed so as to be located on the inner side 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 concave to the first convex portion. The portion 12 is recessed so as to be located inside the outer surface 12b of the first housing 11 in the width direction.

Each end wall portion 15 also includes a thick wall portion 15e that is wide, that is, thick (large in dimension in the X-axis direction), and a thinner wall portion 15e that is connected to the lower side of the thick wall portion 15e. (The dimension in the X-axis direction is small) A thin wall portion 15f is included. 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) than the outer convex surface 15b1. Since the entire outer surface 15b of the end wall portion 15 is recessed so as to be located inward in the longitudinal direction of the first housing 11 than the end surface 14d of the extension end 14, the outer convex surface 15b1 is also located inside the end surface 14d of the extension end 14. It is recessed so as to be positioned inward in the longitudinal direction of the first housing 11 from the end surface 14d.

Further, each end wall portion 15 includes an inner end portion 15g protruding inward in the longitudinal direction of the first housing 11 near the connection portion with the extension end portion 14. The end wall base inner surface 15h, which is the inner surface of the inner end portion 15g, is a surface exposed to the groove portion 13 and is a flat surface extending in the vertical direction (Z-axis direction). The inner 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 located on the outer side in the longitudinal direction of the first housing 11 than the inner convex surface 15c1. Since the entire inner surface 15c of the end wall portion 15 is recessed so as to be located on the outer side in the longitudinal direction of the first housing 11 than the inner surface 15h of the end wall base, the inner convex surface 15c1 also lies on the inner surface 15h of the end wall base. It is recessed so as to be located further outward in the longitudinal direction of the first housing 11 .

Note that the end wall base inner surface 15h, which is the inner surface of the end surface 14d of the extension end 14 and the inner end 15g, is an exposed side surface exposed without being covered by the first reinforcing metal fitting 51 on the side surface of the first protruding end 18. include. Further, the upper surface 14a of the extension end 14 and the upper surface 15a of the end wall 15 are flat surfaces that are flush with each other. ) is recessed so that it is located at

After the left half body part 10A and the right half body part 10B are butted together, that is, the end wall part 15 of the left half body part 10A and the right half body part 10B are brought into contact with each other so that the joining surfaces 15d are in contact with each other. After the end wall portions 15 are abutted, the first reinforcing metal fittings 51 are attached so as to cover and fix at least a portion of the extension end portions 14 and the end wall portions 15 on both sides, and the left half body portion 10A and The right half body portion 10B is coupled.

The first reinforcing metal fitting 51 is a member integrally formed by processing a metal plate by punching, bending, etc., and includes an upper plate extending in the width direction of the first housing 11 and the upper plate. It includes a pair of end wall clamping plates that are connected to both side edges and clamp the end wall part 15, and a pair of extended end clamping plates that are connected to both ends of the upper plate and clamp the extension end part 14. Specifically, the upper plate is connected to an end wall upper surface covering portion 57 that covers the upper surface 15a of the end wall portion 15, and to both left and right ends of the end wall upper surface covering portion 57, and covers the upper surface 14a of the extension end portion 14. The extended end upper surface covering portion 54 is included. The end wall holding plate includes an outer end wall covering portion 52 and an inner end wall covering portion 53 connected to the outer edge and inner edge of the end wall upper covering portion 57. Further, the extension end clamping plate includes a leg portion 55 connected to an outer end of the extension end upper cover portion 54. Note that 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 band-shaped member that extends in the width direction of the first connector 1 as a whole, and covers most of the upper surface 15a of the left and right end wall portions 15 where the coupling surfaces 15d are in contact with each other. It is designed to cover.

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, and the end wall upper surface covering portion 57 is formed by an upper curved portion 52a formed at the upper end. connected to the outer edge. Further, a lower curved portion 52b is formed near 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 covering portion 52 has a roughly S-shape, and the 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 extend inward in the longitudinal direction of the first connector 1 as it goes downward, and the lower curved portion 52b of the first connector 1 is lower than the upper curved portion 52a. Located on the inside in the longitudinal direction. Note that the lower end of the end wall outer covering portion 52 is inclined so as to face outward in the longitudinal direction of the first connector 1, that is, to be spaced apart from the outer surface 15b of the end wall portion 15. Further, the lower end of the end wall outer 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 come into contact with the surface of the first substrate. Note that, if necessary, the lower end of the end wall outer surface covering portion 52 can be made to approach or come into contact with the surface of the first substrate. In this case, by connecting the lower end of the end wall outer covering portion 52 to the connection pad of the first board by soldering or the like, the strength of the connection of the first reinforcing metal fitting 51 to the first board is improved.

The end wall inner covering portion 53 is a plate member that extends in the width direction and the vertical direction of the first connector 1 as a whole, and the end wall upper surface covering portion 57 is formed by an upper curved portion 53a formed at the upper end. attached to the inner edge. Further, a lower curved portion 53b is formed near 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 covering part 53 has a roughly S-shape, and has an upper curved part 53a and a lower curved part 53a. The portion 53b is curved in a direction opposite to that of the portion 53b. Further, the end wall inner covering portion 53 is formed so as to extend outward in the longitudinal direction of the first connector 1 as it goes downward, and the lower curved portion 53b of the first connector 1 is lower than the upper curved portion 52a. Located on the outside in the longitudinal direction. Note that the lower end of the end wall inner covering portion 53 is inclined so as to face inward in the longitudinal direction of the first connector 1, that is, to be spaced apart from the inner surface 15c of the end wall portion 15. Further, the lower end of the end wall inner covering portion 53 is located above the lower surface of the tail portion 56 so as not to come into contact with the surface of the first substrate. Note that, if necessary, the lower end of the end wall inner covering portion 53 can be made to approach or come into contact with the surface of the first substrate. In this case, by connecting the lower end of the end wall inner covering portion 53 to the connection pad of the first substrate by soldering or the like, the connection strength of the first reinforcing metal fitting 51 to the first substrate is improved.

As shown in FIG. 6(c), in the first reinforcing metal fitting 51 before being attached to the first protruding end 18, the interval between the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 is such that the end wall outer surface It is narrowest at the lower curved portion 52b of the covering portion 52 and the lower curved portion 53b of the end wall inner covering portion 53. Specifically, the distance between the inner surface of the upper curved portion 52a of the end wall outer covering portion 52 and the inner surface of the upper curved portion 53a of the end wall inner covering portion 53 is set to L3, and the lower curved portion of the end wall outer covering portion 52 is set as L3. Letting L4 be the distance between the inner surface of 52b and the inner surface of lower curved portion 53b of end wall inner covering portion 53, L3≧L4 (preferably L3>L4). Furthermore, if the thicknesses (dimensions in the X-axis direction) of the thick portion 15e and thin portion 15f of the end wall portion 15 are l3 and l4, respectively, as described later, L3≧l3 (preferably L3>l3). It becomes. Then, before the first reinforcing metal fitting 51 is attached to the first protruding end portion 18, L4<l3, and after the attachment, L4>l4.

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

Furthermore, the extended end upper surface covering portion 54 covers most of the upper surface 14a of the left and right extended end portions 14.

The leg portion 55 is a band-shaped member extending in the vertical direction of the first connector 1, and is connected to the outer end of the extended end upper cover portion 54 by an upper curved portion 55a formed at the upper end. Further, a lower curved portion 55b is formed at the lower end. As shown in FIGS. 5(a) and 5(b), the leg portion 55 has an approximately S-shape when viewed from the longitudinal direction (X-axis direction) of the first connector 1, and has an upper bent portion 55a and a lower bent portion 55a. It is curved in the opposite direction to the side curved portion 55b. Further, the leg portions 55 are generally inclined so as to move toward the inner side in the width direction of the first connector 1 as they go downward, and the lower curved portion 55b is located furthest inside the first connector 1 in the width direction.

As shown in FIG. 6(b), in the first reinforcing metal fitting 51 before being attached to the first protruding end portion 18, the distance between the left and right leg portions 55 is narrowest at the lower curved portion 55b. Specifically, when the distance between the inner surfaces of the left and right upper curved portions 55a is L1, and the distance between the inner surfaces of the left and right lower curved portions 55b is L2, L1≧L2 (preferably L1>L2). There is. Furthermore, if 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 projecting end 18 are l1 and l2, respectively, as will be described later, then L1≧l1 (preferably L1> l1). Then, before the first reinforcing metal fitting 51 is attached to the first protruding end portion 18, L2<l1, and after the attachment, L2>l2.

Due to this relationship, when the first reinforcing metal fitting 51 is attached to the first protruding end portion 18, the inner surfaces 55c of the left and right leg portions 55 reliably sandwich the thick portion 14e of the extension end portion 14. In particular, when L1>l1, the inner surface 55c of the leg portion 55 presses the outer convex lower edge 14b3 (see FIG. 8), which is the lower edge of the thick portion 14e. This prevents the first reinforcing metal fitting 51 from coming off the first protruding end 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. Note that the connection pads can be coupled to conductive traces, such as power lines.

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

FIG. 7 is a two-sided view of a pair of half-body parts abutted against each other in the first embodiment, and FIG. 8 is a sectional view of a main part of a pair of half-body parts abutted against each other in the first embodiment. 9 is a perspective view showing a state immediately before the pair of abutted half parts in the first embodiment are joined by the first reinforcing fitting, and FIG. FIG. 3 is a cross-sectional view of a main part showing a state immediately before the half parts are joined with a first reinforcing metal fitting. In addition, in FIG. 7, (a) is a perspective view, (b) is a top view, and in FIG. 8, (a) is a CC arrow sectional view in FIG. 7(b), and (b) is a 10, (a) is a sectional view taken along line EE in FIG. 9, and (b) is a sectional view taken along line FF in FIG. 9.

When constructing the first connector 1, the operator first butts the left half body 10A and the right half body 10B, as shown in FIG. That is, by butting the end wall 15 of the left half body 10A and the end wall 15 of the right half body 10B, the joining surface 15d at the tip of the end wall 15 of the left half body 10A and the right half body The bonding surface 15d at the tip of the end wall portion 15 of 10A is brought into contact with the bonding surface 15d. As a result, the first protruding end portion 18 is formed.

Next, as shown in FIG. 9, the operator positions the first reinforcing metal fitting 51 above the configured first protruding end 18, and relatively positions the first reinforcing metal fitting 51 on the first protruding end. 18, and the first reinforcing metal fittings 51 are attached so as to cover at least a portion of the extension ends 14 and end wall portions 15 on both sides. In this case, the end wall upper surface covering portion 57 faces the upper surface 15a of the left and right end wall portions 15 with the joining surfaces 15d in contact with each other, and the extension end upper surface covering portion 54 faces the upper surface 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 faces the extension end portion. The posture of the first reinforcing metal fitting 51 is controlled so that it faces the outer surface 14b of the first reinforcing metal fitting 51.

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

Furthermore, the distance between the left and right leg portions 55 is the narrowest at the lower curved portion 55b. Specifically, when the distance between the inner surfaces of the left and right upper curved portions 55a is L1, and the distance between the inner surfaces of the left and right lower curved portions 55b is L2, L1≧L2 (preferably L1>L2). There is. Furthermore, 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). Then, before the first reinforcing metal fitting 51 is attached to the first protruding end portion 18, L2<l1, and after the attachment, L2>l2.

Therefore, when attaching the first reinforcing metal fitting 51 by lowering it relative 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 expanded by the end wall portion 15. The end wall outer covering portion 52 and the end wall inner covering portion 53 are elastically deformed. Further, the distance between the left and right leg portions 55 is expanded 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 protruding end portion 18 is completed, and the left half body part 10A and the right half body part 10B are connected by the first reinforcing metal fitting 51. When connected, the end wall portion 15 is tightened from the front and back due to the spring properties exhibited by the end wall outer covering portion 52 and the end wall inner covering portion 53, and the spring properties exhibited by the left and right legs 55 cause the end wall portion 15 to be extended. The end portion 14 is tightened from the left and right sides. Therefore, the end wall portion 15 is tightened from the front, rear, left and right sides 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 become integral. As a result, the left half body portion 10A and the right half body portion 10B are coupled by the first reinforcing metal fitting 51, and the first connector 1 is configured.

Further, 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 in distance than the distance between the outer convex surface 15b1 and the inner convex surface 15c1, are connected to the outer convex surface 15b1 and Since it is located below the inner convex surface 15c1, when the first reinforcing metal fitting 51 is relatively raised relative to the end wall portion 15 and removed, there is a difference in level 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 covering portion 52 and the lower curved portion 53b of the end wall inner covering portion 53 are caught in the step between the inner concave surface 15c2 and removal becomes 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 have a narrower spacing between them than the spacing between the left and right outer convex surfaces 14b1, are located below the outer convex surfaces 14b1, the first reinforcing metal fittings 51 are relatively When removed by raising it relative to the end wall portion 15, the lower curved portion 55b of the leg portion 55 gets 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.

Further, the distance between the portion of the end wall outer covering portion 52 near the upper curved portion 52a and the portion of the end wall inner 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. When the thick wall 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, the end wall portion 15 of the left half body portion 10A and the right half body portion The end wall portion 15 of 10B is firmly connected.

Similarly, if the distance between the adjacent portions of the upper curved portions 55a of the left and right leg portions 55 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 14e is held between both sides by the legs 55, the end wall 15 of the left half 10A and the end wall 15 of the right half 10B are firmly connected.

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

Similarly, when the distance between the lower curved portions 55b of the left and right leg portions 55 is narrower than the distance between the outer concave surfaces 14b2 of the left and right extension ends 14, the thin wall portions 14f of the extension ends 14 Since they are sandwiched from both sides by the lower curved portion 55b of the portion 55, the end wall portion 15 of the left half portion 10A and the end wall portion 15 of the right half portion 10B are more firmly connected.

Further, in a state where the attachment of the first reinforcing metal fitting 51 to the first protruding 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 surfaces of the first convex portion 12. Since it is 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 the fitting surface 12a or are 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 located on the inner side in the width direction of the first connector 1 than the outer surface 12b of the first convex portion 12, the outer surface of the leg portion 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 located inside the end surface 14d of the extension end portion 14 in the longitudinal direction of the first connector 1, the outer surface of the end wall outer surface covering portion 52 is flush with the end surface 14d or is recessed inward in the longitudinal direction of the first connector 1 from the end surface 14d. That is, the outer surface of the end wall outer covering portion 52 does not protrude from the end surface 14d.

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

Note that the tip of the tail portion 56 connected to the tip of the lower curved portion 55b of the leg portion 55 projects further outward in the width direction of the first connector 1 than the outer surface 12b of the first convex portion 12. Further, the lower surface of the tail portion 56 is substantially flush with the lower surface of the tail portion 62 of the first terminal 61 attached to the first convex portion 12 and the mounting surface 17a of the first housing 11.

Further, the lower end of the end wall outer covering part 52 and the lower end of the end wall inner covering part 53 are located above the lower surface of the tail part 56, and therefore are located above the mounting surface 17a of the first housing 11. Therefore, the lower end of the end wall outer covering part 52 and the lower end of the end wall inner covering part 53 do not come into contact with the surface of the first substrate.

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

FIG. 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 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 fitting surface 111a side (Z-axis positive direction side), there is a substantially rectangular recess 112 surrounded by a first A recess 112 that fits into the housing 11 is formed. A second convex portion 113 as an island portion that fits into the concave groove portion 13 is formed integrally with the second housing 111 within the concave portion 112 . A side wall portion 114 extending parallel to the second convex portion 113 is integrally formed with the second housing 111 .

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

A groove-shaped second terminal receiving groove cavity 115a is formed on both side surfaces of the second convex portion 113 and on the inner side surface of the side wall portion 114. Further, a hole-shaped second terminal receiving hole cavity 115b is formed in the second convex portion 113 and the side wall portion 114. The second terminal accommodating groove cavity 115a and the second terminal accommodating hole cavity 115b are connected to each other at the bottom surface of the recessed groove portion 112a and are integrated with each other. 115b will be described as the second terminal accommodating cavity 115. 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 processing a conductive metal plate by punching or the like, and includes a main body 163 and a tail part 162 connected to the lower end of the main body 163. , a connecting portion 164 extending from near the lower end of the main body portion 163 in the width direction (Y-axis direction) of the second connector 101, and a contact portion extending upward (in the Z-axis positive direction) from the connecting portion 164. 165. Note that it is desirable that a contact convex portion 165a protruding toward the main body portion 163 is formed near the tip of the contact portion 165.

The main body portion 163 is a portion that is press-fitted into and held in the second terminal receiving hole cavity 115b. The tail portion 162 is bent and connected to the lower end of the main body portion 163, extends in the width direction of the second housing 111, and is connected by soldering or the like to a connection pad connected to a conductive trace on the second board. Ru. Note that the conductive trace is typically a signal line. Further, the contact portion 165 is a portion that comes into contact with the first terminal 61 provided in the first connector 1 when the first connector 1 and the second connector 101 are fitted together, and desirably, the contact convex portion 165a is a portion that comes into contact with the first terminal 61 provided in the first connector 1. It engages with a contact recess 65a formed in the contact portion 65 of the first terminal 61.

The second terminal 161 is inserted into the second terminal receiving cavity 115 from below the second housing 111 and attached to the second housing 111. Thereby, in the second terminal 161, the main body portion 163 is press-fitted into the second terminal accommodating hole cavity 115b and held, the contact portion 165 is accommodated in the second terminal accommodating groove cavity 115a and exposed to the concave groove portion 112a, The lower surface of the tail portion 162 is exposed to the mounting surface 111b as the lower surface of the second housing 111.

Further, like the first terminals 61, the second terminals 161 attached to each groove 112a are oriented such that the positions of adjacent terminals are opposite to each other with respect to the width direction of the groove 112a. . In the example shown in FIG. 12, the attitude of the second terminal 161 located at the front end (the end in the X-axis positive direction) among the second terminals 161 attached to the groove portion 112a on the Y-axis positive direction side is such that the tail portion 162 is In contrast, the second terminal 161 located second from the front end is oriented such that the tail portion 62 protrudes in the positive direction of the Y-axis. Directed. In this way, the second terminals 161 are attached to the recessed groove 112a in such a way that they are alternately arranged in opposite directions, so that the pitch of the tail portions 162 exposed on the mounting surface 111b on both sides of the recessed groove 112a is the same as that of the second terminals 161. This is twice the pitch of the two terminals 161. Therefore, connection work such as soldering to the connection pads on the second board can be easily performed. Furthermore, the pitch of the contact portions 165 exposed in the groove portion 112a is also twice the pitch of the second terminals 161.

Furthermore, second projecting end portions 121 as fitting guide portions are provided at both longitudinal ends of the second housing 111, respectively. A fitting recess 122 is formed in each second protruding end 121 as a part of the recess 112 . The fitting recess 122 is a substantially rectangular recess, and is connected to both longitudinal ends of each groove 112a. Then, the first protruding end portion 18 of the first connector 1 is inserted into the fitting recess 122 in a state where the first connector 1 and the second connector 101 are fitted. Further, the second protruding end portion 121 includes a reinforcing metal fitting accommodating recess 126. A second reinforcing metal fitting 151 as a counterpart reinforcing metal fitting is accommodated in the reinforcing metal fitting accommodation recess 126 and attached to the second protruding end portion 121.

The second reinforcing metal fitting 151 is a member integrally formed by processing a metal plate by punching, bending, etc., and includes a second main body portion 152 extending in the width direction of the second housing 111, and a second main body portion 152 extending in the width direction of the second housing 111. A central covering section 157 connected to the upper end of the second main body section 152, a side covering section 153 connected to both left and right ends of the second main body section 152, and a side covering section 153 connected to one side edge of the side covering section 153. and a tail portion 156 connected to the lower end of the second main body portion 152. The tail portion 156 extends outward in the longitudinal direction of the second connector 101 and is connected and fixed to a connection pad (not shown) exposed on the surface of the second board by soldering or the like. Note that the connection pad is preferably connected to a conductive trace, such as a power line.

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

Here, in the first connector 1, the tail portion 62 of the first terminal 61 is connected by soldering or the like to a connection pad connected to a conductive trace on the first board (not shown), and the tail portion of the first reinforcing metal fitting 51 is 56 is surface mounted to the first substrate by being connected, such as by soldering, 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 the conductive trace is connected to the connection pad to which the tail portion 56 of the first reinforcing metal fitting 51 is connected. Assume that the conductive trace is a power line.

Similarly, in the second connector 101, the tail portion 162 of the second terminal 161 is connected by soldering or the like to a connection pad connected to a conductive trace on the second board (not shown), and the tail portion of the second reinforcing metal fitting 151 156 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 the conductive trace 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.

First, the operator places the fitting surface 12a of the first protrusion 12 as the fitting surface 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 to face each other. state, the position of the first convex part 12 of the first connector 1 matches the position of the corresponding concave groove part 112a of the second connector 101, and the position of the first protruding end part 18 of the first connector 1 is in the second connector 101. When the first connector 1 and the second connector 101 match the positions of the corresponding fitting recesses 122, 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 toward the mating side, that is, in the mating direction, the first convex portion 12 and the first protruding end 18 of the first connector 1 are moved. is inserted into the groove 112a and the fitting recess 122 of the second connector 101. This completes the fitting between the first connector 1 and the second connector 101. Then, the first terminal 61 and the second terminal 161 become electrically connected.

As described above, in the present embodiment, the first connector 1 has a pair of left half body parts 10A, each of which includes the first housing 11 and a plurality of first terminals 61 attached to the first housing 11. The first housings 11 of the right half body 10B, the left half body 10A, and the right half body 10B are abutted against each other, and are attached to the first protruding ends 18 formed at both ends of the first housing 11. Each of the first housings 11 includes a first reinforcing metal fitting 51 that connects the half body part 10A and the right half body part 10B, and each of the first housings 11 has a first convex part 12 that extends in the longitudinal direction and holds the first terminal 61. , an extension end 14 connected to both longitudinal ends of the first protrusion 12 , and an end wall 15 extending from the extension end 14 toward the other half, the first protrusion end Each of 18 includes left and right end walls 15 that abut each other and left and right extension ends 14 from which the end walls 15 extend.

Thereby, the distance between the first housings 11 to which the plurality of first terminals 61 are attached can be narrowed, and the first connector 1 can be made smaller. Furthermore, the first connector 1 can be easily manufactured and the reliability of the first connector 1 can be improved.

Further, the first reinforcing metal fittings 51 are connected to an end wall upper surface covering portion 57 and an extended end upper surface covering portion 54 as an upper plate extending in the width direction of the first housing 11, and to both side edges of the upper plate. The end wall outer covering part 52 and the end wall inner covering part 53 serve as a pair of end wall clamping plates that sandwich the section 15, and a pair of extension end clamping plates that are connected to both ends of the upper plate and sandwich the extended end part 14. The end wall top surface covering portion 57 faces the top surface 15a of the end wall portion 15, and the extension end top surface covering portion 54 is connected to both ends of the end wall top surface covering portion 57 to form an extension 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 portions 55 , is connected to the outer end of the extended end upper surface covering portion 54 and faces the outer surface 14b of the extended end portion 14. 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 connected to form the first protruding end portion 18, and the left half body portion 10A and the right The half body portion 10B is reliably joined.

Furthermore, 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, and the outer surface 14b of the extension end 14 is recessed from the outer surface 12b of the first convex portion 12, and the inner surface 15c of the end wall portion 15 is recessed from the outer surface 12b of the first convex portion 12. The covering portion 57 and the extended end upper covering portion 54 do not protrude from the fitting surface 12a of the first convex portion 12, and the end wall outer covering portion 52 and the end wall inner covering portion 53 act as exposed side surfaces of the first protruding end portion 18. The leg portion 55 does not protrude from the outer surface 12b of the first convex portion 12. 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 wall portion 15e and a thin wall portion 15f connected to the lower side of the thick wall portion 15e, and the extension end portion 14 includes a thick wall portion 15e and a thin wall portion 15f connected to the lower side of the thick wall portion 14e. In the first reinforcing metal fitting 51 before being attached to the first protruding end portion 18, the lower curved portion of the end wall outer surface covering portion 52 is the closest portion between the end wall clamping plates. 52b and the lower curved portion 53b of the end wall inner covering portion 53 is narrower than the distance between the outer surface 15b and the inner surface 15c of the portion corresponding to the thick portion 15e of the end wall portion 15, and the distance between the extension end clamping plates The distance between the lower curved portions 55b of the left and right legs 55, which are the closest portions, is narrower than the distance between the outer surfaces 14b of the extended end portion 14 at the portions corresponding to the thick portions 14e. As a result, when the first reinforcing metal fitting 51 is attached to the first protruding end portion 18, the end wall outer covering portion 52 and the end wall inner covering portion 53 are pushed apart, and the left and right legs 55 are pushed apart. Since it is expanded, 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 exhibit spring properties to move the end wall portion 15 back and forth. The left and right legs 55 exert their spring properties to tighten the extension end 14 from the left and right sides. Therefore, the end wall portion 15 is tightened from the front, rear, left and right sides by the first reinforcing metal fittings 51, and the connecting surfaces 15d that are in contact with each other are tightly attached and integrated, so that the first protruding end portion 18 is securely tightened. configured.

Furthermore, the outer surface 15b of the end wall portion 15 includes a step between the outer convex surface 15b1 corresponding to the thick wall portion 15e and the outer concave surface 15b2 corresponding to the thin wall portion 15f, and the inner surface 15c of the end wall portion 15 includes: The outer surface 14b of the extension end 14 includes a step between the inner convex surface 15c1 corresponding to the thick wall portion 15e and the inner concave surface 15c2 corresponding to the thin wall portion 15f. It includes a step between the portion 14f and the corresponding outer concave surface 14b2. As a result, even if an upward external force is applied to the first reinforcing metal fitting 51 attached to the first protruding end 18, the lower curved portion 52b of the end wall outer surface covering portion 52, the end wall inner surface covering portion 53 The lower curved portion 53b and the lower curved portion 55b of the leg portion 55 catch 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. Components having the same structure as those in the first embodiment will be given the same reference numerals and their description will be omitted. Furthermore, descriptions of the same operations and effects as those of the first embodiment will be omitted.

The first reinforcing metal fitting 51 in this embodiment includes a hemispherical projection 58 as a locking projection formed on an end wall outer covering portion 52, an end wall inner covering portion 53, and a leg portion 55. The protrusion 58 has 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 first reinforcing metal fitting 51 is completely attached to the first protruding end portion 18. 15c2, and the step between the outer convex surface 14b1 and the outer concave surface 14b2 of the extension end 14. Therefore, when removing the first reinforcing metal fitting 51 by raising it relative to the end wall portion 15, the protrusion 58 engages with the step, making removal difficult. That is, the function of preventing the first reinforcing metal fitting 51 from coming off is exhibited.

The protrusion 58 is a portion formed by bulging a part of the metal plate constituting the end wall outer covering portion 52, the end wall inner covering portion 53, and the leg portion 55 by performing processing such as pressing. , are formed so as to protrude semispherically from the inner surfaces of the end wall outer covering portion 52, the end wall inner covering portion 53, and the leg portions 55. Note that, as a result of forming protrusions 58 by expanding the metal plate, recesses are formed on the outer surfaces of the end wall outer covering portion 52, the end wall inner covering portion 53, and the leg portions 55 at positions corresponding to the respective protrusions 58. 58a is formed.

The protrusion 58 is formed at at least one location on each of the end wall outer covering portion 52, the end wall inner covering portion 53, and the leg portion 55, but may be formed at two or more locations as necessary. You can. Further, the position of the protrusion 58 in the vertical direction (Z-axis direction) is such that the upper surface 58b of the protrusion 58 abuts the step when the attachment of the first reinforcing metal fitting 51 to the first protruding end portion 18 is completed. It is desirable that the position is as follows.

As described above, in the present embodiment, the first reinforcing metal fitting 51 is a 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. Contains 58. 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 protrusion 58 will cause the outer surface 15b and 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. Therefore, the first reinforcing metal fitting 51 is more reliably prevented from coming off.
