It is provided. In the locking release arm 82, the free end thereof becomes the force point portion 82a. Here, the power point portion 82a is formed in the shape of a rectangular flat plate. Further, the unlocking arm 82 has a wall surface of the fifth outer wall surface 21e of the housing main body 21 which is arranged so as to face each other with a space on the fitting connection portion 21g side. In the locking release arm 82, the locking body 81 is provided on the wall surface opposite to the wall surface and in a protruding state between the fixed end and the free end. In the locking release arm 82 formed in this way, when the locking state between the locking body 81 and the mating locking portion 521h is released, the fifth outer wall surface 21e is relative to the force point portion 82a. The locking release force is applied toward. In the holding structure 80, the unlocking arm 82 is bent by the unlocking force, and the locking body 81 is displaced toward the fifth outer wall surface 21e in conjunction with the bending of the unlocking arm 82. The lockable state between the locking body 81 and the mating locking portion 521h is released.

As shown above, the cover 30 arranges the second wall body 32 so as to face the first outer wall surface 21a side of the fifth outer wall surface 21e at a distance. It covers not only the first outer wall surface 21a side of the outer wall surface 21e but also the free end (that is, the force point portion 82a) of the unlocking arm 82. Therefore, the second wall 32 is provided with a cantilevered flexible portion 32a that covers the force point portion 82a (FIGS. 1 to 3 and 7). The pushing portion 32a is formed in a one-piece shape with the first wall 31 side as a fixed end and the first opening 30a side as a free end, and is pushed and moved toward the fifth outer wall surface 21e. The force point portion 82a in the contact state is pushed and moved toward the fifth outer wall surface 21e to release the lockable state between the locking body 81 and the mating locking portion 521h.

The conductive component EC is housed in the inner space formed by the housing 20 and the cover 30 in the assembled state, and the conductor is electrically connected to the conductor connection portion 12 of the terminal fitting 10 protruding from the terminal outlet 20b. It has a housing area EC1 to be connected and a drawing area EC2 to be pulled out from the drawing port 30c formed by the housing 20 and the cover 30 in the assembled state (FIGS. 2, 4 to 6 and 9). The conductive component EC shown here is divided into a rectangular accommodating area EC1 and a rectangular drawing area EC2. Further, the conductive component EC shown here includes both the conductive member 40 and the reinforcing plate 50, as shown above. In the conductive component EC, the accommodating area EC1 is formed by the conductive member 40 and the reinforcing plate 50, and the drawer area EC2 is formed only by the conductive member 40.

The conductive member 40 includes a plurality of conductors, and a circuit pattern is formed by each of the conductors. The conductive member 40 shown here is a flexible printed circuit board (so-called FPC), and is formed in a rectangular shape.

The conductive member 40 is housed in the inner space formed by the housing 20 and the cover 30 in the assembled state, and the conductor is electrically connected to the conductor connection portion 12 of the terminal fitting 10 protruding from the terminal outlet 20b. It has a conductor connection region 40a to be connected and a conductor extraction region 40b to be drawn outward from the outlet 30c formed by the housing 20 and the cover 30 in the assembled state (FIGS. 2, 4 to 6 and 9). .. The conductive member 40 shown here is divided into a rectangular conductor connecting region 40a and a rectangular conductor drawing region 40b. In the conductive component EC shown here, the accommodation region EC1 is formed by the conductor connecting region 40a of the conductive member 40 in the laminated state and the reinforcing plate main body 51 described later of the reinforcing plate 50, and is drawn out by the conductor drawing region 40b of the conductive member 40. Area EC2 is configured.

The conductor connection region 40a is a through hole through which the conductor connection portion 12 is inserted, and has a through hole 41 for electrically connecting the electrical connection portion of the conductor on the inner peripheral surface of the through hole to the conductor connection portion 12. 4 to 6 and 9). Since the conductor connecting portions 12 of all the terminal fittings 10 are electrically connected to the conductor connecting region 40a shown here, a circular through hole 41 is formed for each of the terminal fittings 10.

The reinforcing plate 50 is formed of an insulating material such as synthetic resin. The reinforcing plate 50 shown here is formed in a flat plate shape (FIGS. 6 and 9). Further, the reinforcing plate 50 shown here has a reinforcing plate main body 51 formed in the same outer shape as the conductor connecting region 40a (that is, a rectangle having the same shape as the conductor connecting region 40a) (FIGS. 4 to 6). And FIG. 9). The accommodating region EC1 of the conductive component EC is configured by integrating the reinforcing plate main body 51 with the conductor connecting region 40a of the conductive member 40 in a laminated state. In the accommodation region EC1, the conductor connection region 40a and the reinforcing plate main body 51 are integrated in a laminated state by attaching the conductor connecting region 40a and the reinforcing plate main body 51 with an adhesive or the like.

The reinforcing plate main body 51 is interposed between the terminal lead-out region 20c of the housing main body 21 and the conductor connection region 40a of the conductive member 40. Therefore, through holes (hereinafter referred to as “terminal insertion holes”) 51a concentric with the through holes 41 are formed in the reinforcing plate main body 51 for each through hole 41 (FIGS. 4 to 6 and 9). .. The terminal insertion hole 51a shown here is formed in the same shape as the through hole 41.

For example, in the accommodating area EC1 of the conductive component EC shown here, the reinforcing plate is inserted by inserting the conductor connecting portions 12 of all the terminal fittings 10 accommodated in the accommodating chamber 20a into the through holes 41 and the terminal insertion holes 51a. The main body 51 is placed on the terminal lead-out area 20c of the housing main body 21. In this connector 1, with the terminal fitting 10, the housing 20, and the conductive component EC (conductive member 40, reinforcing plate 50) installed, soldering is performed for each combination of the paired conductor connecting portion 12 and the through hole 41. Then, the conductor connecting portion 12 and the through hole 41 are fixed to each other. In this connector 1, the cover 30 is then assembled.

By the way, in this connector 1, while the conductor connecting portion 12 is inserted into the through hole 41 and the terminal insertion hole 51a, the conductive component EC is being installed on the terminal fitting 10 and the housing 20, or is installed therefor. When the work is completed and the connection work between the conductor connecting portion 12 and the through hole 41 is possible, the drawing area EC2 (conductor drawing area 40b) of the conductive component EC is in the drawing direction from the outlet 30c. There is a possibility that the worker will pull it. Therefore, in this connector 1, by receiving the pulling force between the housing 20 and the conductive component EC, the conductor connecting portion 12 of the terminal fitting 10 and the through hole 41 and the terminal insertion hole 51a in the conductive component EC are received. Suppresses the transmission of force to and from each of the perimeters of the. In this example, the pulling force is applied between the housing 20 and the reinforcing plate 50.

Specifically, the housing 20 has a protruding direction from the terminal outlet 20b of the conductor connecting portion 12 (hereinafter referred to as “terminal protruding direction”) and a drawing direction from the outlet 30c of the drawing area EC2 (conductor drawing area 40b). (Hereinafter referred to as "conductor pull-out direction") and orthogonal direction (hereinafter referred to as "width direction") are provided one by one with the terminal lead-out areas 20c in between, and a cylinder whose axial direction is the terminal protrusion direction. Alternatively, it has a cylindrical locking projection 24 (FIGS. 2, 4 and 5). The side end portions 90a and 90b in the width direction in the accommodation region EC1 are through holes for each locking projection 24 through which the locking projection 24 is inserted, and the side opposite to the conductor extraction direction side is a semicircular half. It is formed as a circular hole portion 91a, and has a locking hole 91 capable of locking the arc-shaped wall surface of the semicircular hole portion 91a to the locking projection 24 (FIGS. 4 and 9). Further, the through hole 41 has its own before the electrical connection to the conductor connecting portion 12 (that is, before soldering) and when the locking projection 24 and the arc-shaped wall surface of the semicircular hole portion 91a are in the locked state. It is formed so as to provide a gap between the conductor connecting portion 12 and the side opposite to the conductor drawing direction side on the inner peripheral surface. The terminal insertion hole 51a is in a state where the conductor connecting portion 12 and the through hole 41 are before the electrical connection (that is, before soldering), and the locking projection 24 and the arc-shaped wall surface of the semicircular hole portion 91a are locked. Occasionally, it is formed so that a gap is provided between the conductor connecting portion 12 and the side opposite to the conductor drawing direction side on its inner peripheral surface. As a result, in this connector 1, even if the pull-out region EC2 of the conductive component EC is pulled by the operator in the pull-out direction, the force due to the pulling is not transmitted to the terminal fitting 10 and is accommodated with the locking projection 24. It can be received by the peripheral portion of the semicircular hole portion 91a of the locking hole 91 in the region EC1. Therefore, in this connector 1, deterioration of the quality of the terminal fitting 10 and the conductive component EC can be suppressed.

The two locking holes 91 shown here are formed in the conductor connection region 40a in a laminated state and the reinforcing plate main body 51. One of the two locking holes 91 is a circular through hole, and the other is an oval elongated hole whose conductor drawing direction is the longitudinal direction (FIGS. 4 and 9). The circular locking hole 91 is also used as a through hole for positioning when the conductor connecting portion 12 and the through hole 41 are aligned. On the other hand, the locking hole 91 as a long hole is also used to absorb the tolerance variation between the holes and each component.

Here, the conductive component EC of the present embodiment has the shortest distance from the semicircular hole portion 91a on the _{side end faces 90a 1} , 90b ₁ at the side end portions 90a, 90b for each of the side end portions 90a, 90b. It has a piece 92 protruding in the width direction on the same plane as the plane of the accommodation region EC1 from the shortest position Ps (FIGS. 4 and 9). In this conductive component EC, _{the first corner portion 93 on the conductor drawing direction side formed by the side end faces 90a 1} , 90b ₁ of the accommodation region EC1 and the peripheral end face 92a of the single body 92 is in the conductor drawing direction from the shortest position Ps. Placed on the side. Further, in this conductive component EC, the second corner portion 94 on the side opposite to the conductor drawing direction side formed by _{the side end surfaces 90a 1} , 90b _{1 of the accommodation region EC1 and the peripheral end surface 92a of the single body 92 is from the shortest position Ps.} On the opposite side of the conductor drawing direction, the shortest distance from the semicircular hole portion 91a is the outer outer end surface formed by the semicircular hole portion 91a and the accommodation area EC1 and the single body 92 (side end surfaces 90a ₁ , 90b _{1 of the accommodation area EC1).} And is formed to be shorter than the shortest distance between the peripheral end surface 92a) of the single body 92.

Specifically, in this example, one body 92 is provided on the reinforcing plate 50. The reinforcing plate 50 of this example has a single body 52 provided on the side end surface 51b of each side end portion in the width direction of the reinforcing plate main body 51 (FIGS. 4 and 9). _{The side end faces 90a 1} and 90b ₁ of the side end portions 90a and 90b of the conductive component EC include the side end faces 51b of the side end portions of the reinforcing plate main body 51. Therefore, in other words, the reinforcing plate 50 of this example has a single body 52 provided on the side end surface 51b of the reinforcing plate main body 51 in each of the side end portions 90a and 90b of the accommodation region EC1. Each piece 52 is projected in the width direction on the same plane as the plane of the reinforcing plate main body 51 from the shortest position Ps on the side end surface 51b. In the reinforcing plate 50, each piece 52 thereof is used as a piece 92 of the conductive component EC. The first corner portion 93 and the second corner portion 94 are provided between the side end surfaces 51b of the reinforcing plate main body 51 in the reinforcing plate 50 and the peripheral end surface 52a of the piece body 52 in the reinforcing plate 50. Therefore, the first corner portion 93 is a corner portion on the conductor drawing direction side formed by the side end surface 51b of the reinforcing plate main body 51 and the peripheral end surface 52a of the single body 52, and is arranged on the conductor drawing direction side from the shortest position Ps. To. Further, the second corner portion 94 is a corner portion on the opposite side to the conductor drawing direction side formed by the side end surface 51b of the reinforcing plate main body 51 and the peripheral end surface 52a of the single body 52, and is in the conductor drawing direction from the shortest position Ps. On the opposite side to the side, the shortest distance from the semicircular hole portion 91a is between the semicircular hole portion 91a and the peripheral end surface of the reinforcing plate 50 (the side end surface 51b of the reinforcing plate main body 51 and the peripheral end surface 52a of the single body 52). It is formed as being shorter than the shortest distance of.

With such a configuration, in the connector 1 of the present embodiment, when the pulling force in the manufacturing process becomes equal to or more than the reference tensile force, the distance from the semicircular hole portion 91a to the semicircular hole portion 91a becomes large. A crack is formed in the accommodation region EC1 (conductor connection region 40a and the reinforcing plate main body 51) of the conductive component EC toward the shortest second corner portion 94. That is, the conductive component EC (conductive member 40 and reinforcing plate 50) is subjected to a force smaller than the reference tensile force in the conductor drawing direction with respect to the drawing area EC2 (conductor drawing area 40b), and the locking projection 24 and the semicircle are applied. When the arc-shaped wall surface of the hole 91a is locked, the locked state is maintained, while a force equal to or higher than the reference tensile force is applied to the conductor drawing direction with respect to the drawing region EC2, and the locking protrusion is formed. When the 24 and the arc-shaped wall surface of the semicircular hole portion 91a are engaged with each other, a crack is formed from the semicircular hole portion 91a toward the second corner portion 94.

For example, when the conductive component is not provided with a single body 92 as in a conventional connector, the distance from the locking hole to the locking hole when an excessive force is applied in the conductor drawing direction with respect to the drawing region. Cracks toward the shortest position Ps on the side end face of the shortest conductive component or toward the periphery of the shortest position Ps on the side end face. For this reason, in a conventional connector, since the crack is short and the direction of the crack is not determined, it is difficult to find the crack in the manufacturing process. However, in the connector 1 of the present embodiment, the crack is longer than before and the direction of the crack is specified, so that the crack can be easily found in the manufacturing process. Therefore, the connector 1 of the present embodiment is capable of simple quality control in the manufacturing process.

For example, the second corner portion 94 includes a first virtual line connecting the semicircular hole portion 91a and the shortest position Ps at the shortest distance and a second virtual line connecting the semicircular hole portion 91a and the second corner portion 94 at the shortest distance. It may be placed in a place where the angle formed is larger than 45 degrees. Thereby, in the connector 1, the crack from the semicircular hole portion 91a to the second corner portion 94 can be surely made longer than before, and the direction of the crack can be specified.

Further, in the connector 1 of the present embodiment, the shortest distance between the locking hole 91 and the outer shell end surface (peripheral end surface of the reinforcing plate 50) formed by the accommodation area EC1 and the single body 92 is longer than before. Even if a larger tensile force than before is applied to the extraction region EC2 (conductor extraction region 40b), cracks are less likely to occur in the accommodation region EC1 until the tensile force reaches the reference tensile force. That is, since the connector 1 of the present embodiment can increase the strength of the accommodating area EC1 as compared with the conventional case, it is possible to suppress the deterioration of the quality of the conductive component EC from this point as well.

Further, in the connector 1 of the present embodiment, the reinforcing plate 50 may be formed so as to have the above-mentioned piece body 52, the first corner portion 93, and the second corner portion 94, so that the conductive member 40 has versatility. It can be held, and a conventional one can be used for the conductive member 40.

Here, the conductive member 40 is attached to the side end faces of the respective side ends in the width direction in the conductor connection region 40a (that is, the side end faces of the conductor connection regions 40a in the respective side end portions 90a and 90b of the conductive component EC). It may have a one-piece region having the same shape as the one-body 52 of the reinforcing plate 50 and laminated on the one-body 52 (not shown). The one-sided region is a piece that protrudes in the width direction on the same plane as the plane of the conductor connection region 40a from the shortest position Ps on the side end surface of the conductor connection region 40a. That is, in the connector 1, the laminated body of the one body of the conductive member 40 and the one body 52 of the reinforcing plate 50 may be used as the one body 92 of the conductive component EC. In this case, the first corner portion 93 is a corner portion on the conductor drawing-out direction side formed by the side end surface of the conductor connection region 40a of the conductive member 40 and the peripheral end surface of one body of the conductive member 40, and the side end surface of the reinforcing plate main body 51. It is formed by a corner portion on the conductor drawing direction side formed by 51b and the peripheral end surface 52a of the single body 52, and is arranged on the conductor drawing direction side from the shortest position Ps. Further, the second corner portion 94 includes a corner portion on the side opposite to the conductor drawing direction side formed by the side end surface of the conductor connection region 40a in the conductive member 40 and the peripheral end surface of one body in the conductive member 40, and the reinforcing plate main body 51. The side end surface 51b and the peripheral end surface 52a of the single body 52 are formed by a corner portion opposite to the conductor extraction direction side, and the shortest position Ps is opposite to the conductor extraction direction side and half. The shortest distance from the circular hole portion 91a is the outer peripheral end surface formed by the semi-circular hole portion 91a, the accommodating area EC1 and the single body 92 (the peripheral end surface of the conductive member 40 (the side end surface of the conductor connection region 40a and the circumference of the single body of the conductive member 40). It is formed so as to be shorter than the shortest distance between the end face) and the peripheral end face of the reinforcing plate 50).

When the conductive component EC is composed of only the conductive member 40, the accommodating region EC1 is composed of the conductor connecting region 40a, and the locking hole 91 is formed in the conductor connecting region 40a (not shown). In this case, the conductive member 40 has the above-mentioned one-sided region (one body) on each side end surface of the conductor connecting region 40a. The first corner portion 93 and the second corner portion 94 are provided between each side end surface of the conductor connection region 40a of the conductive member 40 and the peripheral end surface of one body of the conductive member 40. That is, the first corner portion 93 is formed by the corner portion on the conductor drawing direction side formed by the side end surface of the conductor connection region 40a in the conductive member 40 and the peripheral end surface of one body in the conductive member 40, and is a conductor rather than the shortest position Ps. It is placed on the pull-out direction side. Further, the second corner portion 94 is formed by a corner portion on the opposite side to the conductor drawing-out direction side formed by the side end surface of the conductor connection region 40a in the conductive member 40 and the peripheral end surface of one body in the conductive member 40. The outermost end surface (peripheral end surface of the conductive member 40) formed by the semicircular hole portion 91a, the accommodating area EC1 and the single body 92 on the side opposite to the conductor extraction direction side from the shortest position Ps and the shortest distance from the semicircular hole portion 91a. It is formed as being shorter than the shortest distance between and.

By the way, in the above example, by providing the one body 92 in the protruding state at an appropriate position in the accommodation area EC1, it is possible to perform simple quality control in the manufacturing process. However, in this connector 1, even if such a single body 92 is not provided, by configuring the accommodating area EC1 as follows, simple quality control in the manufacturing process becomes possible as in the above example. ..

_{Specifically, from the side end faces 90a 1} , 90b ₁ of the side end portions 90a, 90b on the side opposite to the conductor drawing direction side from the semicircular hole portion 91a, respectively, on the side end portions 90a, 90b of the accommodation region EC1. A notched portion 95 is provided (FIG. 10). The cutout portion 95 is formed as having the shortest corner portion 95a having the shortest distance from the semicircular hole portion 91a among the plurality of corner portions. With respect to the shortest corner portion 95a, the shortest distance from the semicircular hole portion 91a is the peripheral end surface of the semicircular hole portion 91a and the accommodation region EC1 (side end surfaces 90a ₁ , 90b ₁ of the side end portions 90a, 90b, respectively). It is formed so as to be shorter than the shortest distance from the end face of the peripheral edge of the containing area EC1. For example, in this example, a rectangular notch 95 is formed. In this example, since the conductive component EC includes the conductive member 40 and the reinforcing plate 50, the notch portion 95 is formed in the conductor connecting region 40a and the reinforcing plate main body 51. However, when the conductive component EC is composed of only the conductive member 40, the notch portion 95 is formed in the conductor connection region 40a.

As a result, in this connector 1, when the force associated with the pulling of the extraction region EC2 (conductor extraction region 40b) in the manufacturing process becomes equal to or greater than the reference tensile force, the semicircular hole portion 91a to the semicircular hole portion 91a A crack is formed in the extraction region EC2 toward the shortest corner portion 95a having the shortest distance from. That is, in the conductive component EC, a force smaller than the reference tensile force is applied in the conductor drawing direction with respect to the drawing area EC2 (conductor drawing area 40b), and the locking projection 24 and the arc-shaped wall surface of the semicircular hole portion 91a are engaged with each other. When it is in the stopped state, the locked state is maintained, and a force equal to or higher than the reference tensile force is applied to the conductor drawing area EC2 (conductor pulling out area 40b) in the conductor drawing direction, so that the locking projection 24 and the semicircle are maintained. When the arc-shaped wall surface of the circular hole portion 91a is engaged, a crack is formed from the semicircular hole portion 91a toward the shortest corner portion 95a. Therefore, in this connector 1, since the direction of the crack is specified, the crack can be easily found in the manufacturing process. Therefore, the connector 1 is capable of simple quality control in the manufacturing process.
