[The problem to be solved by the invention]

At the terminal, in order to obtain a good electrical conduction state, a plating treatment is often applied to the contact surface of the contact portion of the terminal by a plating material with high conductivity. At this time, many expensive materials such as gold are used in the plating process. Therefore, in order to suppress the manufacturing cost of the terminal and even the electrical connector, it is desirable to set the range of plating applied to the terminal to only the contact surface of the contact part of the terminal, and to avoid plating other than the contact surface. The use of packaging materials is kept to a minimum.

Assuming that if it is desired to apply plating to the contact surface (lower surface) of the contact portion formed at the upper arm portion of the first terminal in Patent Document 1, as described above, the lower arm portion of the first terminal supports When viewed from the up and down direction, it is tied to the front and back direction and the terminal width direction and overlaps the entire contact portion with the upper arm. Therefore, the lower arm becomes an obstacle, making it extremely difficult to access from below. The contact surface of the contact part is blown or coated with plating material. Therefore, in order to apply plating to the contact surface of the contact portion of the first terminal, it is generally necessary to immerse the entire first terminal in a plating tank. If plating is applied to the entire first terminal in this way, it will be a part that does not need to be plated, that is, a plating material is also used for parts other than the contact surface. Accordingly, The manufacturing cost of the terminal and even the electrical connector will increase.

In view of this situation, the present invention provides a method for plating a terminal with two arms parallel to each other, even when it is formed on one of the arms of the terminal. When the contact part is located within the range of the other wrist in the longitudinal direction of both arms, it is also possible to apply plating to only the contact part without obstructing the other wrist. , And become a terminal that can suppress the amount of plating material to the minimum necessary, and an electrical connector provided with the terminal, as a problem. [Means to solve the problem]

According to the present invention, the above-mentioned problems are solved by the following terminal of the first invention and the electrical connector of the second invention.

<First invention> The terminal of the first invention is provided at an electrical connector that is inserted and connected with the counterpart connector facing the electrical connector and inserted forward.

In this terminal, in the first invention, the above-mentioned terminal is made of a rolled metal plate, and is a strip-shaped metal plate in which the width direction of the counterpart connector at a right angle with respect to the front-rear direction is the width direction of the terminal The member has a curved shape in the direction of the plate thickness, and is equipped with two wrists extending in parallel to each other toward the rear; and a connecting portion that connects the front ends of the two wrists, allowing for The entry of the opponent's connecting body from the back between the two wrists. One of the two wrists mentioned above is tied in a range that overlaps with the other wrist in the front-to-back direction. There is a contact part that can make contact with the counterpart connector by the calendered surface located on the other arm side. The other arm part is attached to the front and back when viewed from the width direction of the terminal. In the direction that overlaps with the contact part of one of the above-mentioned wrists, the counterpart connecting body that makes contact with the above-mentioned contact part is formed on the rolled surface located on the side of the one of the wrists. The support part used as a support, the support part of the other wrist part is provided with at least a part of the contact part and not in the width direction of the terminal when viewed from the thickness direction of the support part. The above phase is formed by repeating the range.

In the terminal of the first invention, the support portion of the other arm portion is opposed when viewed from the thickness direction of the support portion, that is, from the direction in which the two arm portions oppose each other. It is formed so that at least a part of the contact portion does not overlap in the width direction of the terminal. With this configuration, it is possible to blow a plating material on the contact surface of the contact portion of one of the wrists from the other wrist side in the above-mentioned plate thickness direction. The coating range of the plating material is limited to the contact surface of the contact part and its vicinity. As a result, the amount of plating material used can be kept to the minimum necessary.

In the first invention, the support portion of the other arm may be configured such that the width of the terminal is formed to be larger than that of the other portion of the other arm. By forming the support part in a wide width in this way, the strength of the support part itself is improved. Therefore, even if the support portion is formed in a range that does not overlap in the width direction of the terminal with respect to at least a part of the contact portion, the support portion can be connected to the counterpart through the whole The force received by the contact part of one of the wrists (that is, the force toward the other wrist side) is sufficiently opposed and supports the opponent's connecting body.

In the first invention, the support portion of the other wrist may be configured such that the side edge portion extending in the front-to-rear direction of the support portion is formed with a cutout portion, and is configured to The range of the cutout portion forms a range that does not overlap with at least a part of the contact portion in the width direction of the terminal. In addition, it may also be configured that the support portion of the other arm portion is formed with a hole penetrating the thickness direction of the support portion, and the range of the hole is configured to form a contact with respect to the At least a part of the portion does not overlap in the terminal width direction. In addition, the system may also be configured such that the support part of the other wrist is formed at a position offset from the other part of the other wrist by being formed in the width direction of the terminal, To form a range that does not overlap in the terminal width direction with respect to at least a part of the contact portion.

<Second Invention> The electrical connector of the second invention is characterized by including the terminal of the first invention. By disposing the terminal of the first invention at the electrical connector in this way, the range of plating treatment applied to the terminal at the electrical connector can be limited to the contact surface of the contact portion and its vicinity. As a result, the amount of plating material used can be kept to the minimum necessary.

In the present invention, the so-called "opposite connector" refers to a connector that is electrically connected to an electrical connector. For example, it can be a flat conductor such as an FPC inserted into the electrical connector and The counterpart electric connector etc. which are fitted and connected to the above electric connector. [Effects of the invention]

In the present invention, as described above, in the terminal, the support part of the other arm part is opposed to at least a part of the contact part when viewed from the thickness direction of the support part. It is formed in a range that overlaps in the width direction of the terminal. Therefore, by passing through this range that does not overlap, the thickness direction of the plate is from the other wrist side to one of the wrists. The contact part is coated with plating material, which can limit the range of plating treatment to the contact surface of the contact part and its vicinity. By suppressing the amount of plating material used to the minimum necessary, the manufacturing cost of the terminal and even the electrical connector can be suppressed.

It also includes a second contact portion 31A that is bent and formed to protrude downward at a position near the rear end. The second contact portion 31A is located behind the first contact portion 21A of the first terminal 20 (see also FIG. 3(B)), and becomes the second connection circuit portion in the rear row of the flat conductor F F1B makes the connection. In addition, the rear end 31B of the second contact arm 31 is located behind the rear end 21B of the first contact arm 21 of the first terminal 20 (see also FIG. 3(B)).

The held arm portion 32 of the second terminal 30 extends from the lower end of the second connecting portion 33 toward the rear in parallel with the second contact arm portion 31 and reaches the position of the rear frame portion 10B of the housing 10. The rear end portion of the held arm portion 32 is held by the rear frame portion 10B of the housing 10 by integral molding. In addition, the front end portion of the held arm portion 32 and the second connecting portion 33 are held by the front frame portion 10A by integral mold molding (see also FIG. 3(B)). That is, the held wrist 32 is held by the housing 10 in the shape of supporting beams on both sides as seen in FIG. 3(B).

The held wrist portion 32, as seen in FIG. 3(B), is provided with a front end portion 32A connected to the second connecting portion 33 and a rear end side connected to the second connecting portion 34 The portion 32B and the support portion 32C that is positioned in the range including the second contact portion 31A of the second contact arm portion 31 in the front-rear direction and connects the front end portion 32A and the rear end portion 32B.

Fig. 5 (A) is a plan view of the connector 1 when the movable member 40 is in the open position, and (B) is a bottom view of the connector 1 of (A). As seen in FIG. 5(B), the terminal width (size in the Y-axis direction) of the tip side portion 32A is larger than that of the second contact arm 31 (see also FIG. 5(A)) , And cover the entire area in the front-rear direction with the same width. The rear end portion 32B is formed with a smaller terminal width than the front end portion 32A.

The support portion 32C is generally located within the range of the bottom hole portion 17C of the housing 10 in the front-rear direction and the connector width direction as seen in FIG. 5(B). The support portion 32C is generally positioned in the front-rear direction within the range including the second contact portion 31A of the second contact arm portion 31, in a state where the flat conductor F is connected to the connector 1 , The flat conductor F that makes contact with the second contact portion 31A of the second contact arm portion 31 is supported from below by the rolling surface (support surface) on the upper surface of the support portion 32C (see FIG. 10 ( B)).

The support portion 32C, as seen in FIG. 5(B), is arranged such that the side edge on the Y1 side in the width direction of the connector is offset from the front end portion 32A toward the Y1 side. In the width direction of the connector, the side edge portion on the Y2 side that is located on the opposite side thereof is tied at a position overlapping with the second contact portion 31A in the front and rear direction, and a cutout portion 32C- is formed. 1. The terminal width dimension of the support portion 32C is smaller than the terminal width dimension of the front end portion 32A within the range of the cutout portion 32C-1 in the front-rear direction, and is the same as the rear end portion The terminal width of 32B is slightly equal. In addition, the terminal width dimension of the support portion 32C is larger than the terminal width dimensions of the front end portion 32A and the rear end portion 32B in the range other than the cutout portion 32C-1 in the front-rear direction . In other words, the maximum terminal width of the support portion 32C is larger than the maximum terminal width of the front end portion 32A and the rear end portion 32B.

In this embodiment, the cutout portion 32C-1 of the support portion 32C is formed in the opposite direction (up and down direction) between the second contact arm 31 and the held arm 32 when viewed from A position overlapping with a part of the second contact portion 31A. In other words, in the support portion 32C, in the range of the cutout portion 32C-1, a range that is not overlapped with respect to a part of the second contact portion 31A is formed. That is, as seen in FIG. 5(B), when the second terminal 30 is viewed from below, a part of the second contact portion 31A is within the range of the cutout portion 32C-1. It is exposed and can be visually recognized through the cutout portion 32C-1.

In this way, by coating the plating material through the cutout portion 32C-1, the range where the plating material can be coated can be limited to the contact surface of the second contact portion 31A and its vicinity, so it can be The use amount of the plating material is suppressed to the minimum necessary, and the manufacturing cost of the second terminal 30 can be suppressed. The coating of the plating material by the cutout portion 32C-1 can be performed at any point before and after the integral mold forming between the second terminal 30 and the housing 10.

In addition, in this embodiment, the support portion 32C is formed by expanding the maximum terminal width compared to other portions at the held arm portion 32, that is, the front end portion 32A and the rear end portion 32B. In order to be wide, the strength of the support portion 32C itself is increased. Therefore, even if the support portion 32C is formed with the cutout portion 32C-1 and the flat conductor F is connected to the connector 1, it can be connected to the flat conductor by the entire support portion 32C. The force of F received from the second contact portion 31A of the second contact arm 31 (that is, the downward force) is sufficiently opposed and the flat conductor F is supported. Moreover, it is also possible to provide a circuit part under the flat conductor F and make contact with the support part 32C to electrically conduct the circuit part and the support part 32C, so that the support part 32C can be provided with The function of the contact.

The second connecting portion 34, as seen in FIG. 3(B), extends from the rear frame portion 10B toward the rear (also refer to FIG. 5(B)), and becomes on the lower surface of the circuit board ( The circuit part (not shown) is connected by soldering.

The expanded, substantially plate-shaped main body portion 41, and the protrusion 46 and the rotation shaft portion 47 formed on the rear end side (X2 side) of the main body portion 41 when the movable member 40 is in the closed position.

The main body 41, as seen in FIG. 1, is provided with a cover plate that extends to cover the terminal arrangement range in the width direction of the connector and covers the terminals 20 and 30 from above at the closed position. Section 42 (also refer to Figures 3 (A), (B)), and the end wrist 43 extending backward at the positions on both sides of the covering plate 42 and the end arm 43 extending from the covering plate 42 and the end arm 43 The front ends of the two are connected to each other with a connecting portion 44, and from the connecting portion 44 toward the rear, a locking arm portion 45 extending in the shape of a unilateral support beam (also refer to FIG. 2).

The cover 42 is, as seen in FIG. 1, a hole 42A that communicates with the first groove 46A of the ridge 46 described later in the front-rear direction and the connector width direction at the closed position. , Is formed to penetrate through the cover plate portion 42 in the thickness direction of the cover plate portion 42 (see also FIG. 3(A)).

The end arm 43, as seen in FIG. 2, is such that the lower end of the movable member 40 when the position is in the open position (the rear end when the position is in the closed position) is in the width direction of the connector And it is positioned between the first shaft portion 47A and the second shaft portion 47B described later of the rotating shaft portion 47 and becomes a part of the rotating shaft portion 47, and serves as a connection between the first shaft portion 47A and the second shaft portion 47B The fourth shaft portion 47D is formed.

The locking arm 45, as seen in FIG. 2 where the movable member 40 is in the open position, is tied to the lower end (the movable member 40 is the rear end in FIG. 3(C) where the movable member 40 is in the closed position). ) Is formed with a locking portion 45A protruding toward the front (downward in FIG. 3(C)). The locking portion 45A is as shown in FIG. 3(C). When the movable member 40 is in the closed position, it protrudes from above toward the receiving portion 17A of the housing 10. In addition, the locking portion 45A is as shown in FIG. 3(C). When the movable member 40 is in the closed position, it is provided with a flat conductor F at the back during the insertion process. The guide surface 45A-1 for guiding the flat conductor F toward the front is provided with a guide surface 45A-1 at the front part relative to the flat conductor F formed at the flat conductor F after insertion. The locking portion F3A is a locking surface 45A-2 that can be locked from the rear (see also FIG. 10(C)).

As seen in FIG. 3(C), the guide surface 45A-1 is an inclined surface that inclines downward as it goes to the front when the movable member 40 is in the closed position. The locking arm portion 45 is such that if the front end portion of the front ear portion F3 of the flat conductor F abuts the guide surface 45A-1 during the insertion of the flat conductor F, it will receive the abutting force and The elastic arm part which makes the locking arm part 45 face upward and elastically displaces easily.

In addition, the guide surface 45A-1, as seen in FIG. 4(C), when the movable member 40 is in the open position, it is not inclined but in the vertical direction when viewed from the width direction of the connector Make an extension. In other words, the guide surface 45A-1 is a surface at a right angle with respect to the front-rear direction at the open position. By extending the guide surface 45A-1 in the up-down direction at the open position in this way, as will be described later, after the movable member 40 is formed, the upper mold can be pulled out straight upward.

In addition, the locking surface 45A-2, as seen in FIGS. 3(C) and 10(C), when the movable member 40 is positioned at the closed position, it is not when viewed from the width direction of the connector Extend in the up and down direction without tilting. In other words, the locking surface 45A-2 is a surface at a right angle with respect to the front-rear direction at the closed position. Therefore, in the closed position, the locking surface 45A-2 is positioned behind the locked portion F3A of the flat conductor F, and the locked portion F3A is reliably locked from the rear to prevent flattening. Unexpected fall-off of type conductor F.

In addition, the locking arm 45, as seen in FIG. 2, is located at a position closer to the lower end when the movable member 40 is in the open position, and is provided with a locking position larger than the width of the connector. The portion 45A is a restricted projection 45B formed to protrude further outward. When the movable member 40 is in the closed position, the restricted protrusion 45B enters the space between the front restricting protrusion 16A and the rear restricting protrusion 16B of the housing 10, and is positioned so as to be able to face the front The position where the restricting protrusion 16A comes into contact from the rear and the rear restricting protrusion 16B can come into contact from the front is restricted from movement in the front-rear direction (see FIG. 1). In addition, the restricted protrusion 45B is formed in a range including a part of the locking portion 45A when viewed from the width direction of the connector, and is also responsible for reinforcing the strength of the locking portion 45A. The role of.

The protrusions 46 are formed in plural at positions corresponding to the first terminal 20 at intervals in the width direction of the connector, and are generally formed as seen in FIG. 3(A). The movable member 40 protrudes from the lower surface of the rear end portion of the cover plate portion 42 when the position is at the closed position, and extends toward the rear (see also FIGS. 1 and 2). Each ridge portion 46 is formed with a first groove portion 46A that is sunken from the lower surface (the surface on the receiving portion 17A side) of the slightly front half of the ridge portion 46 when the position is at the closed position. The first groove 46A is formed on the rear end of the first contact arm 21 of the first terminal 20 in a state in which the movable member 40 is in the closed position and is tied in the connector width direction and the front-rear direction. At a position corresponding to 21B, as seen in FIG. 3(A), the rear end 21B of the first contact wrist 21 is housed in the closed position ((also refer to FIG. 9(B)). The first groove 46A is arranged corresponding to the hole 42A of the cover plate 42 as seen in FIGS. 3(A) and 4(A), and communicates with the hole 42A. Also, as seen in FIG. 2, the slightly lower half of the protruding strip 46 at the open position (slightly rear half at the closed position), that is, is located below the first groove 46A ( The part (the partition wall 46C described later) at the rear of the closed position covers the entire area of the ridge portion 46 in the connector width direction (Y-axis direction) and becomes a solid center (see also FIG. 9(A) ), (B)).

Between the adjacent protrusions 46, in other words, the position corresponding to the rear end 31B of the second contact arm 31 of the second terminal 30 in the connector width direction is as shown in the figure As seen in 2, it is generally formed with a second groove 46B extending in the open position and extending in the vertical direction (front-rear direction at the closed position) covering the entire area of the ridge 46 (see also FIG. 3(B) And Figure 4(B)). As seen in FIG. 3(B), the second groove portion 46B is formed at the slightly lower half of the open position (slightly rear half of the closed position), that is, is larger than the first groove 46A. In the groove-shaped portion further below (behind the open position), when the movable member 40 is in the closed position, the rear end 31B of the second contact arm 31 is accommodated (see also FIG. 9(B)) .

In this way, in this embodiment, in the state where the movable member 40 is in the closed position, the rear end 21B of the first contact arm 21 is housed in the first groove 46A, and in the second groove 46B The rear end 31B of the second contact arm 31 is housed in the system. By this, the inner wall surface of the first groove 46A and the inner wall surface of the second groove 46B that are at right angles to the width direction of the connector, The unintended displacement of each of the first contact arm 21 and the second contact arm 31 in the connector width direction is restricted. In addition, during the insertion process of the flat conductor F into the connector 1, the flat conductor F does not interact with the rear end 21B of the first contact arm 21 and the rear end 31B of the second contact arm 31. In the case of contact, it is possible to prevent damage to the terminals 20 and 30 due to buckling or the like.

Furthermore, in the present embodiment, in a state where the position is in the closed position, the position of the protruding ridge 46 is located behind the first groove 46A (below the open position) (in other words, The portion separating the above-mentioned groove-like portions of the adjacent second groove portions 46B from each other) forms a partition wall 46C, which covers the entire area of the protruding portion 46 in the connector width direction (Y-axis direction) Become a solid in the middle.

In this embodiment, the second contact wrist is positioned at its rear end closer to the rear end of the housing 10 than the rear end of the first contact wrist. In other words, the rear end is positioned at At the opening side of the receiving portion 17A. At the beginning of the insertion of the flat conductor F, that is, just after the insertion of the flat conductor F into the rear end of the receiving portion 17A is started, due to the position of the flat conductor F in the width direction of the connector and The posture is still unstable. Therefore, the rear end of the second contact arm is more likely to receive unexpected external force from the flat conductor F in the connector width direction than the rear end of the first contact arm.

However, in the present embodiment, the partition wall 46C is set to be solid in the middle, and the thickness dimension (the dimension in the width direction of the connector) of the partition wall 46C is increased as much as possible, as in the above-mentioned general manner. As a result, since the strength of the partition wall 46C itself can be increased, it can be ensured even when the distance between the second terminals 30 has to be reduced when a large number of terminals 20 and 30 are provided. There is sufficient strength of the partition wall 46C. Therefore, it can be made more sure by the side surface of the partition wall 46C (a surface at right angles to the width direction of the connector), in other words, by the inner wall surface of the groove-shaped portion of the second groove 46B. The ground restricts the unexpected displacement of the second contact arm 31 in the width direction of the connector.

As seen in FIG. 2, at the lower part (the rear part when the movable member 40 is in the closed position) of the partition wall 46C of each protrusion 46, on the side surfaces on both sides of the connector width direction, The system is formed with an inclined surface 46C-1 that is inclined toward the inside in the connector width direction as it goes forward (downward when the movable member 40 is in the closed position). In this way, in the present embodiment, the inclined surface 46C-1 is formed on the partition wall 46C. Therefore, even when the movable member 40 is in the open position, the second contact of the second terminal 30 The rear end 31B of the wrist 31 is slightly offset from the normal position in the width direction of the connector. During the rotation of the movable member 40 from the open position to the closed position, the rear end 31B also It comes into abutment and sliding contact with the inclined surface 46C-1, and is surely guided into the second groove 46B of the movable member 40. Therefore, during the rotation, it is possible to prevent the rear end 31B from contacting the partition wall 46C and causing the second contact arm 31 to deform unexpectedly. In addition, as described above, the partition wall 46C is formed with a large wall thickness. Therefore, even if the inclined surface 46C-1 is formed at the partition wall 46C, the sufficient strength of the partition wall 46C is ensured.

As described above, the first groove 46A communicates with the hole 42A of the cover plate 42. As seen in FIGS. 3(A) and 4(A), the inner wall surface of the first groove 46A and the hole 42A The inner wall surface of the system forms a continuous plane. The continuous inner wall surface of the first groove portion 46A and the hole portion 42A and the inner wall surface of the second groove portion 46B, when viewed from the width direction of the connector, when the movable member 40 is in the open position, is not It extends obliquely and straightly toward the front and rear direction (refer to Figure 4 (A), (B)). When the movable member 40 is in the closed position, it is inclined backward as it goes downward (refer to Figure 3 (A) ), (B)).

Therefore, when it is desired to mold the movable member 40 and the housing 10 by the same process and manufacture the connector 1, as long as the movable member 40 is in the open position, the molding is performed by The mold portion used to mold the movable member 40 moves straight in the front-rear direction, so that the first groove 46A and the second groove 46B can be easily formed.

In addition, as described above, the inner wall surface forming the first groove 46A, when the movable member 40 is in the closed position, when viewed from the connector width direction, it is inclined toward the rear as it goes downward (see Figure 3(A)). Therefore, in the closed position, the inner wall surface of the inner wall surface of the first groove portion 46A located on the rear side (X2 side) becomes the first terminal 20 received from the first groove portion 46A. It is arranged so as to contact the rear end 21B of the wrist 21 and leave. As a result, interference between the movable member 40 and the rear end 21B of the first contact arm 21 from the open position toward the closed position can be avoided more reliably, and damage to the first contact arm 21 can be prevented.

As seen in Figure 4 (A) and (B), when the movable member 40 is in the open position, the first groove portion 46A and the second groove portion 46B of the movable member 40 are positioned in contact with the first The rear end 21B of the wrist 21 and the second contact with the rear end 31B of the wrist 31 are further rearward (see also FIG. 9(A)). That is, the rear end 21B and the rear end 31B are not located in the first groove 46A and the second groove 46B, respectively. Therefore, when it is desired to mold the movable member 40 and the housing 10 by the same process and manufacture the connector 1, as long as the movable member 40 is in the open position, the mold is molded. In order to avoid interference with the rear end 21B of the first contact arm 21 and the rear end 31B of the second contact arm 31, it is unnecessary to provide the mold parts corresponding to the first groove 46A and the second groove 46B. It is a complicated shape, and it can be set as the simple shape corresponding to the 1st groove part 46A and the 2nd groove part 46B. As a result, it is secured to the above-mentioned mold part to ensure sufficient strength, and damage can be avoided.

The rotation shaft portion 47 of the movable member 40 has a non-cylindrical outer peripheral surface around the rotation axis, and extends in the connector width direction at a position including the rotation axis of the movable member 40, and includes the following The first shaft portion 47A, the second shaft portion 47B, the third shaft portion 47C, and the fourth shaft portion 47D. As seen in FIG. 2, in the state where the movable member 40 is in the open position, the first shaft portion 47A starts from the fourth shaft portion 47D which becomes the lower end of the end arm portion 43 and faces the connector width. The width direction protrudes outside.

The third shaft portion 47C, when the movable member 40 is in the open position, as seen in FIG. 7(C), has a cross-sectional shape at right angles to the width direction of the connector, and the vertical direction is taken as It is a substantially pentagonal shape in the longitudinal direction. The upper surface of the outer peripheral surface is a flat surface extending straight without being inclined with respect to the front-rear direction, and the rear surface of the lower part is formed as a flat surface inclined rearward as it goes upward. Here, the upper surface of the third shaft portion 47C at the open position seen in FIG. 7(C) is referred to as "flat surface 47C-1", and the rear surface of the lower part is referred to as "flat surface 47C-2" ". At this open position, the third shaft portion 47C, as seen in FIG. 7(C), makes the flat surface 47C-1 come into surface contact with the lower surface of the movement restricting portion 51 of the clip 50, thereby, The movable member 40 is maintained at the open position.

In the state where the movable member 40 is rotated to the closed position, as seen in FIG. 6(C), the flat surface 47C-1 (the upper surface in the open position) is inclined forward as it goes upward It is arranged in the same manner as the front surface of the third shaft portion 47C. In addition, the flat surface 47C-2 (the rear surface of the lower part in the open position) is arranged so as to extend straight without being inclined with respect to the front-rear direction, and becomes the upper surface of the third shaft portion 47C. At this closed position, the third shaft portion 47C, as seen in FIG. 6(C), makes the flat surface 47C-2 surface contact with the lower surface of the movement restricting portion 51 of the fastener 50, thereby, The movable member 40 is maintained at the closed position.

Therefore, during the rotation, the position of the third shaft portion 47C in the vertical direction is such that the third shaft portion 47C receives the abutting force from the movement restricting portion 51 and moves up and down. That is, the third shaft portion 47C has a function as a so-called cam portion.

In this embodiment, as seen in FIGS. 6(A) and 7(A), the first shaft portion 47A is attached to the front inner wall surface 18A-1 and the rear inner wall surface 18A of the outer housing portion 18A. Each of -2 is housed in the outer housing portion 18A in a state where a gap in the front-rear direction (hereinafter referred to as a "front-rear gap") is formed between each of them. In this embodiment, the front-rear gap between the movable member 40 and the front inner wall surface 18A-1 is referred to as "C1", and the front-rear gap between the movable member 40 and the rear inner wall surface 18A-2 is defined as "C2" (refer to Fig. 6(A) and Fig. 7(A)). As can be seen by comparing Fig. 6(A) with Fig. 7(A), the dimensions of the front-rear gaps C1 and C2 in the closed position are larger than the front-rear gaps C1 and C2 in the open position. smaller. In this way, the first shaft portion 47A has a shape in which the front-rear clearances C1 and C2 in the closed position are further reduced compared to the front-rear clearances C1 and C2 in the open position.

Also, as seen in FIGS. 6(B) and 7(B), the second shaft portion 47B is formed between the shaft restricting surface 16C-1 which is the upper surface of the shaft restricting protrusion 16C. In a state where there is a gap in the vertical direction (hereinafter referred to as a "vertical gap"), it is accommodated in the inner housing portion 18B. In this embodiment, the vertical clearance between the movable member 40 and the shaft restricting surface 16C-1 when the movable member 40 is in the closed position is set to "C3" (see FIGS. 6(B) and 7(B)) ). As can be seen by comparing FIG. 6(B) with FIG. 7(B), the size of the vertical clearance C3 in the closed position is generally smaller than the vertical clearance C3 in the open position. In this way, the second shaft portion 47B has a shape in which the vertical clearance C3 when in the closed position is reduced more than the vertical clearance C3 when in the open position.

The housing 10 and the movable member 40 are so-called simultaneous molded products, and are generally molded by the same process when the connector 1 is manufactured as described later. In this embodiment, it is molded with the movable member 40 in the open position. When the housing 10 and the movable member 40 are molded, a part of the mold is removed from the gaps C1 and C2 in the front and rear directions. It is inserted in the vertical direction (see FIG. 8(A)), and a part of the mold is inserted in the vertical direction gap C3 from the front-rear direction. As described above, the front-to-rear gaps C1, C2, and the vertical gap C3 are so that the size at the open position is larger than the size at the closed position, so it can be inserted into the front-rear gap C1. The front-rear dimension of the mold part in C2 and the vertical dimension of the mold part inserted into the vertical gap C3 are increased, and sufficient strength can be ensured at these mold parts.

In this embodiment, when the movable member 40 is in the open position, the front-rear gaps C1 and C2 at the position of the first shaft portion 47A are formed with equal gap sizes and formed in the vertical direction. A slit extending straight. When the movable member 40 is in the open position, the vertical gap at the position of the second shaft portion 47B is provided with slits formed in the front-rear direction and linearly extending in the same gap size. Therefore, the shape of the mold part inserted into each of the front-rear direction gaps C1, C2, and the vertical direction gap C3 during the molding of the movable member 40 can be linear and simplified.

In addition, when the connector is used, the movable member 40 is moved from the open position to the closed position. The front and rear clearances C1, C2, and the vertical clearance C3 are compared to when the movable member 40 is in the open position. And become smaller. Therefore, the front-to-rear gaps C1, C2, and the vertical gap C3 are below the allowable gap. When the connector is used, even the flat conductor F receives external force in the front-rear direction (plug-in direction) and the vertical direction. The shaking in the front-rear direction at the position of the first shaft portion 47A is also suppressed, and the shaking in the vertical direction at the position of the second shaft portion 47B is also suppressed. As a result, it becomes difficult to adversely affect the contact state between the flat conductor F and the terminals 20 and 30.

The buckle 50, as seen in FIG. 2, is located at a position corresponding to the outer receiving portion 18A of the housing 10 and the third shaft portion 47C of the movable member 40 in the width direction of the connector. The side wall 15 of the body 10 is molded and held by an integral mold. The fastener 50 is formed by bending a strip made of a rolled metal plate in its thickness direction, and its rolled surface (plate surface) is in a posture parallel to the width direction of the connector, and It is held at the side wall 15.

The buckle 50, as seen in FIGS. 2, 6(C), and 7(C), is provided with a movement restricting portion 51 extending in the front-rear direction, and a front end of the movement restricting portion 51 The front held portion 52 that is bent and extends downward and is held at the housing 10, and the rear end of the movement restricting portion 51 that extends in a crank shape and is held at the housing 10 The holding portion 53 and the fixing portion 54 extending rearward from the rear held portion 53 to the outside of the housing 10.

The movement restricting portion 51, as seen in FIGS. 6(C) and 7(C), is located in the outer receiving portion 18A of the housing 10, and in the front-rear direction, that is, in the outer receiving portion 18A The front inner wall surface 18A-1 and the rear inner wall surface 18A-2 of the front inner wall surface 18A-1 and the rear inner wall surface 18A-2 extend toward the front and rear than the third shaft portion 47C of the movable member 40 in the opposing direction, and are exposed from the housing 10.

In this embodiment, the movement restricting portion 51 has its rolled surface (plate surface) at right angles to the vertical direction (connector thickness direction), in other words, the vertical direction is the plate thickness direction. Therefore, according to the present embodiment, compared to the case where the rolling surface (plate surface) of the plate-shaped movement restricting portion is set at a right angle to the width direction of the connector, the movement restriction is The vertical dimension of the portion 51 becomes smaller. Therefore, it is possible to reduce the size in the vertical direction of the housing 10 holding the fastener and even the connector 1.

In this embodiment, the lower surface of the movement restricting portion 51 is arranged in contact with the upper surface of the third shaft portion 47C (the flat surface 47C-1 in the closed position and the flat surface 47C-1 in the open position). However, instead of this, a slight gap may be formed between the lower surface of the movement restricting portion 51 and the upper surface of the third shaft portion 47C. In this case, the movement restricting portion 51 restricts the movement to the upper side of the third shaft portion 47C by a specific amount or more, and the specific amount corresponds to the size of the gap.

Moreover, as seen in FIG. 2, the movement restricting portion 51 is provided in the middle position in the width direction of the connector in the outer housing portion 18A. The spaces of each part of the outer housing portion 18A on both sides of the movement restricting portion 51 in the width direction of the connector are designed to cover the entire area in the vertical direction when viewed in the front-rear direction Become a method of equal width and be formed. That is, the above-mentioned space does not have a general shape that narrows its width as it goes upward. Therefore, when the connector 1 is manufactured, a part of the mold (the upper mold M1 described later) can be arranged from above at a position corresponding to the above-mentioned space, and the part of the mold can be coordinated with the movement restricting portion 51 The function is to be able to perform integral molding between the fastener 50 and the housing 10.

The front held portion 52 is, as seen in FIGS. 6(C) and 7(C), and extends through a front curved portion 52A that is curved downward at the front end of the movement restricting portion 51. The front held portion 52 is formed by an integral mold so that the whole is buried and held by the housing 10.

The rear portion to be held 53 is, as seen in FIGS. 6(C) and 7(C), through the rear upper bending portion 53A that is bent downward at the rear end of the movement restricting portion 51. It extends and further extends through the rear lower bending portion 53B that is bent toward the rear, and becomes a crank shape as a whole system. The rear portion to be held 53 is embedded and held by the housing 10 by integral molding.

In this way, the buckle 50 is held at the housing 10 by integral molding with the held parts 52 and 53. Therefore, compared to the case where the fastener is pressed into and held at the shell, the contact area between the fastener 50 and the shell 10 (that is, the area of the fastener 50 that is held by the shell 10) ) Is large, and the fastener 50 is firmly held by the housing 10. As a result, even if the movement restricting portion 51 receives a strong contact force from the third shaft portion 47C when restricting the movement of the third shaft portion 47C, it is also operated with sufficient strength against the contact force. It is possible to restrain the movement of the third shaft portion 47C more reliably.

In the present embodiment, since the front held portion 52 and the rear held portion 53 (hereinafter, collectively referred to as "holding portions 52, 53" as needed) are formed, they are formed in the direction of the plate thickness. The curved portions (the front curved portion 52A, the rear upper curved portion 53A, and the rear lower curved portion 53B) are formed, so that the strength of the held portions 52 and 53 themselves can be improved. In addition, by forming the bent portion in this way, the held portions 52 and 53 held in the housing can be lengthened, and the housing 10 can be molded integrally with the housing 10 The area of the contact surface between 10 increases, and the holding force caused by the housing 10 can be improved.

The fixed portion 54 extends linearly from the rear held portion 53 toward the rear and extends from the side wall 15. The fixing portion 54 is located at the same height as the lower surface of the housing 10 in FIGS. 6(C) and 7(C), and becomes a corresponding portion on the mounting surface of the circuit board, by It is fixed by welding. By providing the fixing portion 54 at the clip 50 in this way, the clip 50 is fixed to the mounting surface of the circuit board by the fixing portion 54. Therefore, the movement restricting portion 51 is When the movement of the third shaft portion 47C of the movable member 40 is restricted, it can counteract the contact force received from the third shaft portion 47C with sufficient strength.

The movement restricting portion 51 of the buckle 50 is held at the housing 10 by the held portions 52, 53 formed on both sides in the front-rear direction with respect to the movement restricting portion 51, and therefore moves The restricting portion 51 is shaped like a supporting beam on both sides. Therefore, when the movement of the third shaft portion 47C of the movable member 40 is restricted by the movement restriction portion 51, it is possible to have sufficient strength against the contact force received from the third shaft portion 47C. To contend.

The connector 1 having the above configuration is manufactured by the following method.

First, the terminals 20, 30 and the fastener 50 are arranged so that the rolled surfaces of these members are parallel to the width direction of the connector, and the molds (the upper mold M1, the lower mold M2, and the The rear mold M3), and is held by the mold. Specifically, the upper mold M1 is arranged from above, the lower mold M2 is arranged from below, and the rear mold M3 is arranged from the rear (see Figure 8 (A), (B) ), the first contact arm portion 21 of the first terminal 20, the held arm portion 32 of the second terminal 30, and the movement restricting portion 51 of the clip 50 are held.

At this time, at the position of the first shaft portion 47A in the width direction of the connector, as seen in FIG. 8(A), there are gaps C1 and C2 between the front and rear directions in the front and rear directions (see FIG. 7 ( A)) The corresponding position is the mold part M1A where the upper mold M1 is arranged from above and the mold part M2A where the lower mold M2 is arranged from below. In addition, at the position of the second shaft portion 47B in the width direction of the connector, at a position corresponding to the vertical clearance C3 (refer to FIG. 7(B)) in the front and rear direction, it is arranged from the rear The mold part (not shown) of the rear mold M3.

In this embodiment, since the movable member 40 is molded in the open position, it is ensured that there are large front-to-back clearances C1 and C2, the mold part M1A of the upper mold M1 and the mold part of the lower mold M2. M2A is formed to have a thickness dimension (a dimension in the front-rear direction) corresponding to the gaps C1 and C2 in the front-rear direction. Therefore, it is possible to ensure the strength corresponding to the thickness dimension at the mold parts M1A, M2A, and it is possible to prevent damage to the mold parts M1A, M2A well. In addition, since the large vertical gap C3 is also secured, the mold part of the rear mold M3 is formed to have a thickness dimension (vertical dimension) corresponding to the vertical gap C3. Therefore, it is possible to ensure the strength corresponding to the thickness dimension at the mold part, and it is possible to prevent damage to the mold part well.

At the position of the fastener 50 in the width direction of the connector and the third shaft portion 47C of the movable member 40, as seen in FIG. 8(B), the upper mold M1 and the movement restricting portion of the fastener 50 The upper surface of the whole 51 abuts, and the mold part M2B of the lower mold M2 is brought into contact with the lower surface of the front end side portion and the rear end side portion of the movement restricting portion 51. In this way, the upper and lower surfaces of the flat rolling surface of the movement restricting portion 51 are used as abutting surfaces with the dies M1 and M2.

In this embodiment, the lower mold M2 is located outside the terminal arrangement range in the connector width direction, and is in a range that overlaps with the space in the mold for molding the housing 10 (specifically, When viewed from below, in the middle accommodating portion 18C (refer to FIG. 5(B)) of the housing 10, the lower mold M2 is penetrated in the vertical direction to form a movable member mold for molding the movable member 40 Use space (not shown). In the movable member molding space, a movable member molding gate block (not shown) for molding the movable member 40 is arranged from below. The gate block for molding a movable member is formed by injecting molten electrical insulating material from an injection port of the gate block for molding a movable member into the space in the mold for molding the movable member 40.

In addition, one of the molds is located at a position different from the above-mentioned movable member molding space, and penetrates through the mold to form a housing molding space (not shown) for molding the housing 10. In this space for housing molding, a gate block for housing molding (not shown) for molding the housing 10 is arranged. This gate block for shell molding is used to inject molten electrically insulating material from the injection port of the gate block for shell molding into the space in the mold for molding the shell 10.

Next, by cooling and solidifying the electrical insulating material injected into the mold from each of the gate block for molding of the movable member and the gate block for molding of the casing, the casing 10 and the body are in the open position. The lower movable member 40 is simultaneously molded. At this time, the aforementioned terminals 20 and 30 and the fastener 50 are held at the housing 10 by integral molding. Also, as seen in FIG. 8(B), the position of the fastener 50 in the width direction of the connector is tied in the outer housing portion 18A of the housing 10, and the movement of the fastener 50 is restricted. In the space enclosed by the lower surface of the movement restricting portion 51 and the lower mold M2, the third shaft portion 47C of the movable member 40 is brought into contact with the lower surface of the movement restricting portion 51. Is formed.

Next, the gate block for molding of the movable member is pulled out from the space for molding of the movable member, and the gate block for molding of the casing is pulled out from the space for molding of the casing, and removed. At this time, by pulling out the gate block for molding the movable member, an intermediate housing portion 18C is formed in the housing 10. In addition, the upper mold M1 is moved straight upward (Z1 direction), the lower mold M2 is moved straight downward (Z2 direction), and the rear mold M3 is moved straight backward (X2 direction) for removal. .

Also, in this embodiment, as described above, since the movable member 40 is molded with the position in the open position, immediately after the molding, the movable member 40 is viewed from the width direction of the connector In this case, the guide surface 45A-1 of the locking portion 45A extends straight in the vertical direction (see FIG. 4(C)). Therefore, when the upper mold M1 is removed, since the upper mold M1 can be pulled upward along the guide surface 45A-1, it can be manufactured by the simple shape of the upper mold M1 Connector 1.

After the molds M1, M2, and M3 are removed, the third shaft portion 47C of the movable member 40 is moved from the fastener 50 by rotating the movable member 40 from the open position toward the closed position. The lower surface of the movement restricting portion 51 is separated, and the movable member 40 is made movable, whereby the connector 1 is completed in a usable state. The rotation operation of the movable member 40 can be performed at any stage after the molds M1, M2, and M3 are removed. For example, it can be performed by the manufacturer before the connector 1 is shipped. After the connector is shipped, it is performed by the user at the beginning of the use of the connector.

In this way, the connector 1 of the present embodiment can be formed by molding the terminals 20, 30 and the fastener 50 together with the housing 10 and the movable member 40 simultaneously by integrally molding the movable member 40 Move between the open position and the closed position to be manufactured. Therefore, it is not necessary to perform any processing on the components of the connector after the integral mold is formed, and the connector can be easily manufactured with a small number of processes. In addition, corresponding to the reduction in engineering, the manufacturing cost of the connector can be suppressed.

In this embodiment, the movable member molding space of the lower mold M2 is in a range that overlaps with the space in the mold for molding the housing 10, on the lower side of the connector thickness direction (up and down direction) That is, it is formed by opening at the side opposite to the side (upper side) where the movable member 40 is provided. Therefore, even in the case where the movable member cannot be formed on the upper side of the mold due to the structure of the mold (shape, division position, etc.), that is, the movable member cannot be placed on the upper side of the mold for molding. When a gate block is used, a movable member molding space may be formed in advance on the lower side of the mold, and the movable member molding gate block may be arranged in the movable member molding space to mold the movable member 40. In addition, since the gate block for housing molding is arranged at a position different from that of the gate block for molding of the movable member, the housing 10 and the movable member 40 can be molded by the same process.

In addition, in this embodiment, the gate block for molding the movable member is arranged at the position of the intermediate housing portion 18C (see FIG. 5(B)) of the housing 10, and the injection port of the gate block for molding the movable member The system position is in the range of the fourth shaft portion 47D (refer to FIG. 5(B)) of the movable member 40. Therefore, on the surface of the fourth shaft 47D which is the part where the injection port is arranged, after the movable member 40 is molded, when the gate block for molding the movable member is removed, a so-called Traces of injection. This injection trace may be formed in a protrusion shape protruding from the surface of the fourth shaft portion 47D. In the present embodiment, since the fourth shaft portion 47D located outside the range of the receiving portion 17A of the housing 10 in the width direction of the connector is formed with an injection trace, even if the injection trace becomes a protrusion Therefore, the injection trace will not be located at a position protruding from the receiving portion 17A. As a result, it is possible to prevent the flat conductor F from interfering with the injection trace during and after the insertion of the flat conductor F into the receiving portion 17A.

In this embodiment, when the movable member 40 is molded, the gate block for molding the movable member is arranged at the position of the intermediate receiving portion 18C outside the terminal arrangement range in the width direction of the connector. Therefore, the gate block for molding the movable member does not interfere with the terminals 20 and 30. Therefore, in the mold, the movable member molding space is formed in a simple shape extending linearly in the connector thickness direction (up and down direction) toward the space in the mold (space for molding the movable member). Yes, without complicating the shape or structure of the mold. In addition, the position where the gate block for forming the movable member is arranged is not limited to the outside of the terminal arrangement range, as long as it is a position that can avoid interference with the terminal or the fastener, for example, It can be the position between adjacent terminals.

Next, the connection operation between the connector 1 and the flat conductor F will be described.

First, the first connection portion 22 of the first terminal 20 and the second connection portion 34 of the second terminal 30 of the connector 1 are soldered to the corresponding circuit portion of the circuit board (not shown), and the clip 50 is fixed The portion 54 is soldered to the corresponding portion of the circuit board. By soldering the first connecting portion 22, the second connecting portion 34, and the fixing portion 54, the connector 1 is mounted on the circuit board.

Next, as shown in FIG. 1, at the rear of the connector 1 with the movable member 40 in the closed position, the flat conductor F is placed along the mounting surface of the circuit board (not shown) It is arranged to extend in the front-rear direction. Next, the flat conductor F is inserted into the receiving portion 17A of the connector 1 toward the front.

In the process of inserting the flat conductor F into the receiving portion 17A, the front end of the flat conductor F first abuts against the second contact portion 31A of the second contact arm portion 31 of the second terminal 30, and this The upward component of the contact force pushes up the second contact portion 31A, and thereby elastically displaces upward. If the flat conductor F is further inserted, the tip of the flat conductor F is brought into contact with the first contact portion 21A of the first contact arm 21 of the first terminal 20, and is placed on the first contact portion 21A. Push, and thereby make it elastically displaced upward.

As seen in Fig. 10(A) and (B), in the state where the insertion of the flat conductor F is completed, the first contact arm 21 of the first terminal 20 and the second contact arm of the second terminal 30 The portion 31 is still maintained in a state of elastic displacement. As a result, the first contact portion 21A and the second contact portion 31A are maintained as the first connection circuit portion F1A and the second connection circuit portion F1B (refer to FIG. 1) for the flat conductor F, and each is provided with a contact pressure ground. The state of making contact.

In the process of inserting the flat conductor F into the receiving portion 17A, the front ears F3 located near both ends in the width direction of the flat conductor F are tied to the front ears F3 formed on the movable member 40 The guide surface 45A-1 of the locking portion 45A at the locking arm portion 45 abuts and makes sliding contact, and the flat conductor F is guided to the correct insertion position in the vertical direction. In addition, the front ear portion F3 is elastically displaced upward and moved to allow the insertion of the flat conductor F by the vertical component of the contact force between the front ear portion 45A-1 and the guide surface 45A-1. Location. If the flat conductor F is inserted further, and the front ear part F3 passes through the position of the locking part 45A, the locking arm part 45 will be displaced downward to reduce the amount of elastic displacement and return to a free state. And it protrudes into the notch F2 of the flat conductor F. As a result, in the inserted state of the flat conductor F seen in FIG. 10(C), the locked portion F3A of the flat conductor F is located in front of the locking surface 45A-2 of the locking portion 45A At a position that can be locked with the locking surface 45A-2, the flat conductor F is prevented from being pulled out toward the rear. In addition, the locking arm 45 does not need to be completely restored to a free state. For example, the system may also be configured such that the locking portion 45A is projected into the cutout portion F2 of the flat conductor F while the locking arm portion 45 is left with a slight amount of elastic displacement. The position where F3A is locked.

When the flat conductor F in the state shown in FIGS. 10(A) to (C), that is, in the connection state with the connector 1, is intentionally pulled out from the connector 1, the system The movable member 40 positioned at the closed position is rotated and moved to the open position (see FIG. 4(C)). When the position of the movable member 40 is at the open position, the locking portion 45A of the locking arm portion 45 of the movable member 40 is disposed so as to be separated upward from the cutout portion F2 of the flat conductor F. That is, the locked state of the locking portion 45A of the locked portion F3A of the flat conductor F is released, and the pulling out of the flat conductor F toward the rear is allowed. However, in this state, if the flat conductor F is pulled backward, the flat conductor F can be easily pulled out from the connector 1.

In this embodiment, the second terminal 30 is configured to have a cutout formed in the support portion 32C of the held arm portion 32 in order to be able to perform the plating process on the second contact portion 31A from below. The portion 32C-1, however, is not limited to the above-mentioned cutout portion in order to be a portion that can be plated from below, and can be formed in various shapes.

11(A) and (B) show the second terminal 130 in a modified example as a single body, (A) is a perspective view, and (B) is a bottom view. In this modification, the second terminal 130 is formed with a hole 132C-1 at the supporting portion 132C. At this point, it is the same as the present embodiment in which a cutout portion 32C-1 is formed at the supporting portion 32C. The second terminal 30 in the form is different in structure. The second terminal 130 has the same basic shape as the second terminal 30 of the present embodiment except for the support portion 132C. Therefore, the description is centered on the shape of the support portion 132C, and the other parts are , The reference numeral "100" is added to the reference numeral of the second terminal 30 of the present embodiment, and the description is omitted.

As seen in Figs. 11(A) and (B), the supporting portion 132C of the held wrist 132 of the second terminal 130 is made such that its side edges are compared with other parts of the held wrist 132 ( The side edges of the front end portion 132A and the rear end portion 132B) are located further outside in the terminal width direction (Y-axis direction), and the terminal width dimension is larger than the other portions and becomes wider. Wide. At an intermediate position in the terminal width direction of the support portion 132C, a hole portion 132C-1 is formed that penetrates the support portion 132C in the thickness direction (up-down direction) and extends in the front-rear direction.

As seen in FIG. 11(B), the hole 132C-1 is formed at a position overlapping with a part of the second contact portion 131A when the second terminal 130 is viewed from below . In other words, at the support portion 132C, a range that does not overlap with a part of the second contact portion 131A is formed in the range of the hole portion 132C-1. That is, when the second terminal 130 is observed from below, a part of the second contact portion 131A is exposed through the hole portion 132C-1 and is visible.

Therefore, the second terminal 130 is blown and plated by passing through the hole 132C-1 from below the held arm 132 toward the contact surface of the second contact portion 131A of the second contact arm 131 The material is capable of coating the plating material on the contact surface. As a result, since the range where the plating material is applied can be limited to the contact surface (lower surface) of the second contact portion 131A and its vicinity, the usage of the plating material can be suppressed to the minimum necessary.

In addition, in this embodiment, the support portion 132C is the same as described above. Compared with other parts at the held arm portion 132, it is expanded in the terminal width direction and formed into a wide width. The strength of the support portion 132C itself Department increased. Therefore, even if the hole 132C-1 is formed in the supporting portion 132C, the supporting portion 132C can also be connected to the second contact portion 131A of the flat conductor F from the second contact arm portion 131 by the entire supporting portion 132C. The received force (the downward force) is fully opposed and supports the flat conductor F from below.

11(C) and (D) show the second terminal 230 in another modification as a single body, (C) is a perspective view, and (D) is a bottom view. The second terminal 230 in this modified example is formed in the terminal width direction by displacing the entire supporting portion 232C relative to the second contact portion 231A in the terminal width direction. A range that does not overlap with the second contact portion 231A. At this point, it is formed by the cutout portion 32C-1 of the support portion 32C and the second contact portion 31A is not in the terminal width direction. The second terminal 30 in the present embodiment in the overlapping range differs in structure. The second terminal 230 in the modified example has the same basic shape as the second terminal 30 of this embodiment except for the held arm 232, so the shape of the held arm 232 is taken as the center. In the description, for other parts, the reference numerals of the second terminal 30 of the present embodiment are added with the reference numerals "200", and the description is omitted.

The held wrist 232, as seen in Figs. 11(C) and (D), is tied to two positions in the front and rear direction, and is directed to one side in the terminal width direction (Y-axis direction) (Y2 side) It is bent and extended, and becomes a crank shape when viewed in the vertical direction. The held arm portion 232 is formed with a support portion 232C in a range between two bending positions in the front-rear direction. The support portion 232C is generally as seen in FIG. 11(D), and the entire support portion 232C is offset in the terminal width direction relative to the second contact portion 231A, that is, is formed opposite It is at a position that does not overlap the second contact portion 231A. That is, when the second terminal 230 is observed from below, a part of the second contact portion 131A is exposed and becomes a visually recognizable state.

Therefore, at the second terminal 230, by blowing the plating material from below the held arm 232 toward the contact surface (lower surface) of the second contact portion 231A of the second contact arm 231, it is possible to Coating the plating material on the contact surface. As a result, since the range in which the plating material is applied can be limited to the contact surface of the second contact portion 231A and the vicinity thereof, the use amount of the plating material can be suppressed to the minimum necessary.
