Description

The present invention relates to a terminal and a connector unit using the terminal.

Conventionally, a connector unit has been proposed in which a terminal and a terminal on the other side are electrically connected in a state of being in pressure contact with each other. For example, examples of the terminal used in this type of connector unit include a terminal having a U-shaped shape as a whole (so-called clip terminal) so as to sandwich the mating terminal between a pair of contact portions (for example, Patent Document 1). , 2). The clip terminal is applied to, for example, a service plug for disconnecting a high-voltage battery mounted on an electric vehicle, a hybrid vehicle, or the like and an in-vehicle circuit at the time of maintenance.

By the way, when making an electrical connection while bringing the above-mentioned conventional terminal closer to the mating terminal, the frictional force generated between the terminal and the mating terminal is exerted on the terminal in a direction that hinders the movement of the terminal. The external force required to connect the terminal while moving it with respect to the other terminal against this frictional force is hereinafter referred to as "insertion force". In particular, when both the terminal and the mating terminal are plated with the same plating material, the coefficient of friction between the two becomes large because frictional bonding occurs locally at the interface between the two. Large insertion force may be required. Further, if the amount of movement of the terminal with respect to the other terminal is large in such a state that a large insertion force is required, it is difficult to improve the workability of the work of assembling the terminals to each other.

The present invention has been made in view of the above-mentioned situation, and an object of the present invention is to provide a terminal having excellent workability for assembling with a mating terminal and a connector unit.

In order to achieve the above-mentioned object, the terminal and the connector unit according to the present invention are characterized by the following [1] to [4].

A terminal that will be electrically connected in a state of being in pressure contact with the other terminal.
A contact portion that is electrically connected to the conductive portion of the mating terminal,
A contact portion that comes into contact with a contact portion different from the conductive portion,

When assembling the terminal and the mating terminal, the contact portion abuts on the contacted portion and is displaced so as to approach the conductive portion, and the contact portion is displaced so as to approach the conductive portion. The contact portion is configured to press contact with the conductive portion with elastic deformation of the connecting portion.

[2]
At the terminal described in [1] above,
The contact portion has a curved shape so as to project toward the conductive portion.
The contact portion has a curved shape so as to project toward the contact portion.
Must be a terminal.
[3]
In the terminal described in the above [1] or the above [2],
The terminal is
It has a clip-like shape in which the pair of the contact portions are arranged so as to face each other and the pair of the contact portions are arranged so as to face each other.
By expanding the distance between the pair of contact portions by the contacted portion, the distance between the pair of contact portions is increased, and each of the pair of contact portions corresponds to the contact portion. Configured to press and contact the conductive part,
Or,
By narrowing the distance between the pair of contact portions by the contacted portion, the distance between the pair of contact portions is reduced, and each of the pair of contact portions corresponds to the contact portion. Configured to press and contact the conductive part,

[4]
A connector unit comprising a mating connector having a mating terminal and a connector having a terminal that is electrically connected in a state of being in pressure contact with the mating terminal.
The other side connector is
The conductive portion provided on the mating terminal and
It has a contacted portion different from the conductive portion, and has.
The terminal is
A contact portion that is electrically connected to the conductive portion,
The contact portion that comes into contact with the contacted portion and
It has an elastically deformable connecting portion that connects the contact portion and the contact portion.
When mating the connector and the mating connector
The contact portion abuts on the contacted portion and is displaced so as to approach the conductive portion, and the contact portion is displaced so as to approach the conductive portion. Pressing contact with elastic deformation,
Must be a connector unit.

According to the terminal having the configuration of [1] above, when the terminal and the mating terminal are assembled, the contact portion of the terminal abuts on the contacted portion and is displaced so as to approach the conductive portion, and the contact portion is conductive. Displace to get closer to the part. Then, the contact portion displaced in this way presses and contacts the conductive portion with elastic deformation of the connecting portion. In other words, as long as the contact portion is not displaced, the contact portion is located at a position away from the conductive portion, so that no frictional force is generated between the contact portion and the conductive portion. As an example, when connecting the two while bringing the terminal close to the other side terminal, by adjusting the timing at which the contact part and the contacted part come into contact with each other, the contact part of the terminal and the conductive part of the other side terminal can be connected. The timing at which the pressing contact starts can be adjusted. Further, for example, by forming the contacted portion with a resin or the like, the frictional force generated between the contacted portion and the contacted portion can be reduced. As a result, it is possible to shorten the distance for moving the terminal with respect to the mating terminal in a state where the contact portion is in pressure contact with the conductive portion (that is, in a state where an insertion force is required). As a result, the terminals having this configuration are superior in workability for assembling with the mating terminal as compared with the conventional terminals described above.

According to the terminal having the configuration of [2] above, the contact portion has a curved shape so as to project toward the conductive portion, so that the contact portion can slide smoothly with respect to the conductive portion. The same applies to the sliding between the abutted portion and the abutted portion. As a result, the terminal of this configuration is further excellent in workability for assembling with the terminal on the other side.

According to the terminal having the configuration of [3] above, the distance between the pair of contact portions of the terminals having a clip-like shape is expanded by the contacted portion (for example, the pair of contact portions presses the contacted portion. By sandwiching), the distance between the pair of contact portions of the terminals becomes large, and each of the pair of contact portions makes a pressing contact with the corresponding conductive portion. On the contrary, the distance between the pair of contact portions of the clip-shaped terminals is narrowed by the contacted portion (for example, the pair of contact portions are sandwiched by the contacted portion), so that the pair of terminals is paired. The distance between the contact portions is reduced, and each of the pair of contact portions makes a pressing contact with the corresponding conductive portion. As described above, according to the terminal having the present configuration, the present invention can be concretely realized as a terminal having a clip-like shape.

According to the connector unit having the configuration of [4] above, the mating connector having the mating terminal and the connector having the terminal to be electrically connected in the state of being in pressure contact with the mating terminal are fitted. At this time, the contact portion of the terminal abuts on the contacted portion and is displaced so as to approach the conductive portion, and the contact portion is displaced so as to approach the conductive portion. Then, the contact portion displaced in this way presses and contacts the conductive portion with elastic deformation of the connecting portion. In other words, as long as the contact portion is not displaced, the contact portion is located at a position away from the conductive portion, so that no frictional force is generated between the contact portion and the conductive portion. As an example, when connecting the two while bringing the terminal close to the other side terminal, by adjusting the timing at which the contact part and the contacted part come into contact with each other, the contact part of the terminal and the conductive part of the other side terminal can be connected. The timing at which the pressing contact starts can be adjusted. Further, for example, by forming the contacted portion with a resin or the like, the frictional force generated between the contacted portion and the contacted portion can be reduced. As a result, it is possible to shorten the distance for moving the terminal with respect to the mating terminal in a state where the contact portion is in pressure contact with the conductive portion (that is, in a state where an insertion force is required). As a result, the connector unit having this configuration is superior in workability for assembling with the mating terminal as compared with the connector unit having the conventional terminals described above.

As described above, according to the present invention, it is possible to provide a terminal having excellent workability and a connector unit using the terminal.

The present invention has been briefly described above. Further, the details of the present invention will be further clarified by reading through the embodiments described below with reference to the accompanying drawings.

<Embodiment>
Hereinafter, the connector unit 1 according to the embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the connector unit 1 includes a connector 2 and a mating connector 3. When the connector 2 and the mating connector 3 are fitted, the terminal 30 housed in the connector 2 (see FIG. 2) and the mating terminal 50 housed in the mating connector 3 (see FIG. 2) are electrically connected. Is connected.

The connector unit 1 is typically mounted on an electric vehicle, a hybrid vehicle, or the like, and is a service plug for disconnecting an in-vehicle high-voltage battery and an in-vehicle circuit during maintenance or the like to ensure worker safety. Used as. Hereinafter, for convenience of explanation, as shown in FIGS. 1 to 4, "front-back direction", "width direction", "vertical direction", "front", "rear", "top" and "bottom" are defined. The "front-back direction", "width direction", and "vertical direction" are orthogonal to each other.

As shown in FIGS. 1 and 2, the connector 2 includes a housing 10, a lever 20 rotatably supported by the housing 10, and a terminal 30 housed in the housing 10. The mating side connector 3 includes a mating side housing 40 and a mating side terminal 50 housed in the mating side housing 40. Hereinafter, first, each component constituting the connector 2 will be described in order.

First, the housing 10 will be described. As shown in FIG. 1, the resin housing 10 has a substantially flat plate shape extending in the width direction and the front-rear direction and long in the front-rear direction. As shown in FIG. 2, a fitting portion 11 is formed at the center of the lower surface of the housing 10 in the front-rear direction. The fitting portion 11 has a fitting space 12 that opens downward. The fitting portion 11 will be fitted with the fitting portion 41 described later of the mating housing 40.

As shown in FIG. 2, a groove portion 13 that is recessed upward and opens downward is formed in the central portion of the fitting portion 11 in the width direction so as to extend in the front-rear direction in the fitting space 12. A pair of substrate portions 32, which will be described later, of terminals 30 are press-fitted and fixed in the groove portions 13.

Next, the lever 20 will be described. The lever 20 serves a function of assisting the fitting operation between the housing 10 and the mating housing 40. As shown in FIG. 1, the resin lever 20 is composed of a pair of arm portions 21 extending in the front-rear direction and a connecting portion 22 extending in the width direction by connecting one ends of the pair of arm portions 21 to each other. The liver.

The fulcrum portion 24 located near the tip portion 23 on the connecting portion 22 side from the tip portion (other end portion) 23 of the pair of arm portions 21 is rotatably supported by the housing 10 on both outer sides in the width direction of the housing 10. ing. As a result, the lever 20 is connected to the housing 10 with the first position (sleeping posture, see FIG. 1) in which the connecting portion 22 is located in front of the front end of the housing 10 with the pair of fulcrum portions 24 as the center. The portion 22 can rotate between the second position (standing posture) located above the fulcrum portion 24.

Next, the terminal 30 will be described. As shown in FIG. 2, the terminal 30 is a so-called clip terminal having a substantially U-shaped shape when viewed from the front-rear direction. The terminal 30 is formed by pressing, bending, or the like on an elongated rectangular metal plate.

Specifically, the terminals 30 are a flat plate-shaped top plate portion 31 extending in the width direction and the front-rear direction, and a pair of top plate portions 31 hanging from both ends in the width direction and facing each other in the width direction and extending in the front-rear direction. A flat plate-shaped substrate portion 32, a pair of first curved portions 33 that are continuous under the pair of substrate portions 32 and are curved so as to project outward in the width direction and extend in the front-rear direction, and a pair of first curved portions. It is composed of a pair of second curved portions 34 that are continuous to the lower side of 33 and are curved so as to project inward in the width direction and extend in the front-rear direction. The entire surface of the terminal 30 is plated with a metal material such as tin and silver.

Here, the top of the first curved portion 33 (the outermost portion in the width direction) constitutes the contact portion 35, and the top of the second curved portion 34 (the innermost portion in the width direction) is formed. The portion that constitutes the contact portion 36 and connects the contact portion 35 and the contact portion 36 constitutes the connecting portion 37 (see FIG. 2). As shown in FIG. 3A, the pair of contact portions 35 are located outside the pair of contact portions 36 in the width direction in a state where the terminals 30 are not elastically deformed. The distance C between the widthwise outer end faces of the pair of contact portions 35 and the distance B between the widthwise inner end faces of the pair of contact portions 36 can be changed by elastic deformation of the terminal 30 in the width direction.

The pair of substrate portions 32 of the terminals 30 are press-fitted and fixed to the groove portions 13 of the housing 10 (see FIG. 2). As a result, the terminal 30 projects downward from the fitting space 12 of the fitting portion 11 so that the pair of contact portions 35 and the pair of contact portions 36 are located below the opening of the fitting portion 11. It is fixed to the housing 10. The components constituting the connector 2 have been described above. Next, each component constituting the mating housing 40 will be described in order.

First, the mating side housing 40 will be described. As shown in FIG. 1, the resin mating housing 40 has a shape extending in the width direction and the front-rear direction and long in the front-rear direction. As shown in FIGS. 1 and 2, a fitting portion 41 is formed in the central portion of the mating housing 40 in the front-rear direction. The fitting portion 41 has a fitting space 42 that opens upward.

At the center of the fitting portion 41 in the width direction, a flat plate-shaped contacted portion 43 extending in the vertical direction is provided so as to extend in the front-rear direction in the fitting space 42. The resin-made contacted portion 43 is inserted between the pair of abutting portions 36 of the terminals 30. At the upper end corner of the resin-made contacted portion 43, a pair of tapered surfaces 43a inclined from the vertical direction are formed so as to extend in the front-rear direction. As shown in FIG. 1, the mating housing 40 has a pair of engaging protrusions that engage with the pair of tip portions 23 of the lever 20 when the lever 20 rotates from the second position to the first position. 44 is provided.

Next, the other side terminal 50 will be described. The metal mating terminal 50 is fixed to the fitting portion 41 of the mating housing 40. The mating terminal 50 includes a pair of flat plate-shaped conductive portions 51 facing each other in the width direction and extending in the front-rear direction. The pair of conductive portions 51 define a pair of widthwise end faces of the fitting space 42. A pair of contact portions 35 of the terminals 30 will be inserted between the pair of conductive portions 51. One conductive portion 51 is electrically connected to the vehicle-mounted high-voltage battery, and the other conductive portion 51 is electrically connected to the vehicle-mounted circuit. The entire surface of the mating terminal 50 is plated with the same metal material as the terminal 30.

As shown in FIG. 3A, in a state where the terminal 30 is not elastically deformed, the width A of the contacted portion 43 is larger than the distance B between the pair of contact portions 36 of the terminal 30 (A> B). ), And the distance D between the inner end faces of the pair of conductive portions 51 in the width direction is equal to or greater than the distance C between the pair of contact portions 35 (D ≧ C). The parts constituting the mating housing 40 have been described above.

Next, the fitting operation between the connector 2 and the mating connector 3 will be described. In order to fit the connector 2 and the mating connector 3, first, the fitting portion 11 of the housing 10 fits the mating housing 40 while the lever 20 is held in the second position (upright posture). The housing 10 and the mating housing 40 are arranged so as to be located above the portion 41.

Next, the housing 10 and the mating housing 40 are brought close to each other in the vertical direction, and the fitting portion 11 and the fitting portion 41 are semi-fitted. In this process, the pair of contact portions 36 of the terminals 30 first abut on the pair of tapered surfaces 43a of the contacted portions 43, and then the force received from the tapered surfaces 43a is applied outward in the width direction. It rubs on the tapered surface 43a while increasing the amount of elastic deformation outward in the width direction. That is, while the pair of abutting portions 36 rubs on the pair of tapered surfaces 43a, the interval B (see FIG. 3A) gradually increases, and the interval C (see FIG. 3A) also increases accordingly. It will increase. The terminal 30 is not elastically deformed before the pair of contact portions 36 abut on the pair of tapered surfaces 43a. Therefore, even if the pair of contact portions 35 enter between the pair of conductive portions 51, the pair of contact portions 35 do not come into pressure contact with the pair of conductive portions 51 due to the above-mentioned “D ≧ C” relationship. ..

Here, the frictional force generated when the metal contact portion 36 and the resin contact portion 43 (tapered surface 43a) are rubbed is smaller than the frictional force generated between the metals. Therefore, even if the inclination angle of the tapered surface 43a from the vertical direction is increased, the vertical force (so-called insertion force) required for advancing the fitting of the housing 10 and the mating housing 40 is maintained at a small value. Easy to do. Therefore, the vertical inclination angle of the tapered surface 43a can be increased to shorten the vertical length of the tapered surface 43a, so that the housing 10 while the pair of contact portions 36 rubs on the tapered surface 43a. The amount of vertical movement (stroke) of the mating housing 40 with respect to the housing 40 can be reduced.

When the pair of abutting portions 36 pass through the lower end edges of the pair of tapered surfaces 43a, the increase in the amount of elastic deformation of the pair of abutting portions 36 outward in the width direction (that is, the increase in the intervals B and C) stops thereafter. At the same time, the pair of contact portions 36 rubs on the pair of side surfaces of the contacted portions 43 that are in press contact with each other. At this stage, since the gap B is expanded to the width A of the contacted portion 43, the gap C of the pair of contact portions 35 is also the gap D of the pair of conductive portions 51 (see FIG. 3A). ) Try to get bigger. However, at this stage, since the pair of contact portions 35 have already entered between the pair of conductive portions 51, the interval C cannot be larger than the interval D. As a result, the pair of contact portions 35 come into pressure contact with the pair of conductive portions 51 with elastic deformation of the pair of connecting portions 37.

In this way, in the state where the fitting portion 11 and the fitting portion 41 are semi-fitted, the gap C between the pair of contact portions 35 is increased by expanding the gap B between the pair of contact portions 36 by the contacted portion 43. It becomes larger (see the white arrow pointing outward in the width direction in FIG. 3B), and the pair of contact portions 35 are in press contact with the pair of conductive portions 51.

Next, by pushing the connecting portion 22 of the lever 20 forward and downward, the lever 20 is rotated from the second position (standing posture) to the first position (sleeping posture). In this process, the pair of tip portions 23 of the lever 20 continue to press the pair of engaging protrusions 44 of the mating housing 40 upward (see FIG. 1), so that the fulcrum portion 24 is used as a fulcrum and the connecting portion 22 is used. The lever 20 (that is, the housing 10 that supports the lever 20) moves downward relative to the mating housing 40 by the "lever principle" in which the tip portion 23 is the point of effort and the tip portion 23 is the point of action (that is, the housing 10 that supports the lever 20). That is, the fitting progresses). In this way, the lever 20 functions to assist the fitting operation between the housing 10 and the mating housing 40.

In this way, in the process in which the fitting progresses due to the rotation of the lever 20, the pair of contact portions 36 rubs on the pair of side surfaces of the contacted portions 43 that are in press contact as described above. , The pair of contact portions 35 rubs on the inner wall surface of the pair of conductive portions 51 that are in press contact. Here, the rubbing frictional force between the metal contact portion 35 and the metal conductive portion 51 is larger than the rubbing frictional force between the metal contact portion 36 and the resin contacted portion 43. This is because the friction coefficient tends to increase due to local frictional bonding at the interface between the terminal 30 and the mating terminal 50, which are plated with the same plating material. Ru.

That is, at this stage, the insertion force tends to increase. However, according to the above-mentioned "principle of the lever", the lever 20 can be easily rotated (that is, the fitting is advanced) only by pressing the connecting portion 22 of the lever 20 with a small force. Further, in the process of increasing the distance C between the pair of contact portions 35, the pair of contact portions 35 do not come into pressure contact with the pair of conductive portions 51, so that the pair of contact portions 35 are paired with the conductive portions 51. The amount (stroke) of the housing 10 moving in the vertical direction with respect to the mating housing 40 can be reduced while rubbing on the inner wall surface of the housing 10.

When the rotation of the lever 20 progresses and the lever 20 reaches the first position, the fitting of the fitting portion 11 and the fitting portion 41 (that is, the fitting of the connector 2 and the mating connector 3) is completed. , The connector unit 1 shown in FIG. 1 is obtained. When the mating of the connector 2 and the mating connector 3 is completed, as shown in FIG. 2, each of the pair of contact portions 35 of the terminals 30 presses and contacts the corresponding conductive portions 51 of the mating terminal 50. Is electrically connected. As a result, the vehicle-mounted high-voltage battery connected to one conductive portion 51 and the vehicle-mounted circuit connected to the other conductive portion 51 are electrically connected via the terminal 30.

In this way, when the maintenance of the vehicle is performed in the state where the mating of the connector 2 and the mating side connector 3 is completed, the connector 2 is removed from the mating side connector 3. As a result, the connection between the terminal 30 and the mating terminal 50 is cut off, and the electrical connection between the pair of conductive portions 51 is cut off, so that the high voltage battery and the vehicle-mounted circuit are cut off. As a result, the safety of maintenance workers is ensured.

<Action / effect>
As described above, according to the terminal 30 and the connector unit 1 according to the present embodiment, the terminal that is electrically connected to the mating side connector 3 having the mating side terminal 50 in a state of being in pressure contact with the mating side terminal 50. When mating with the connector 2 having 30, the pair of abutting portions 36 of the terminals 30 are expanded by the abutted portions 43 to be displaced so as to approach the pair of conductive portions 51, and the pair of contacts. The portion 35 is also displaced so as to approach the pair of conductive portions 51. Then, the pair of contact portions 35 displaced in this way press-contact with the pair of conductive portions 51 with elastic deformation of the respective connecting portions 37. In other words, as long as the contact portion 36 is not displaced, the contact portion 35 is located at a position away from the conductive portion 51, so that no frictional force is generated between the contact portion 35 and the conductive portion 51. That is, by adjusting the timing at which the contact portion 36 and the contacted portion 43 come into contact with each other, the timing at which the pressing contact between the contact portion 35 of the terminal 30 and the conductive portion 51 of the mating terminal 50 starts can be adjusted. Further, since the contacted portion 43 is made of resin, the frictional force generated between the contacted portion 36 and the contacted portion 43 can be reduced. As a result, it is possible to shorten the vertical distance for moving the terminal 30 with respect to the mating terminal 50 in a state where the contact portion 35 is in pressure contact with the conductive portion 51 (that is, in a state where a relatively large insertion force is required). .. As a result, the connector unit 1 according to the present embodiment is superior in workability as compared with the connector unit having the above-mentioned conventional terminals.

<Other aspects>
The present invention is not limited to each of the above embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, and the like. In addition, the material, shape, dimensions, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.

For example, in the above embodiment, as shown in FIG. 3A, the contacted portions 43 of the mating housing 40 are arranged inside the pair of contact portions 36 of the terminals 30 in the width direction, and the pair of terminals 30 are paired. In a state where the pair of conductive portions 51 of the mating terminal 50 are arranged outside the contact portion 35 in the width direction and the terminals 30 are not elastically deformed, the width A of the contacted portion 43 is in contact with the pair. It is larger than the distance B of the portions 36 (A> B), and the distance D between the inner end faces of the pair of conductive parts 51 in the width direction is equal to or more than the distance C of the pair of contact parts 35 (D ≧ C). As a result, as shown in FIG. 3B, the distance C between the pair of contact portions 35 is increased by expanding the distance B between the pair of contact portions 36 by the contacted portion 43, and as a result, the pair of contact portions 35 are paired. The contact portion 35 presses and contacts the inner end faces of the pair of conductive portions 51 in the width direction.

On the other hand, as shown in FIG. 4A, the pair of contact portions 36 and the pair of contact portions 35 in the terminal 30 of the above embodiment are used as the pair of contact portions 35 and the pair of contact portions 36, respectively. Then, a pair of flat plate-shaped contacted portions 43 are arranged at the positions of the pair of conductive portions 51 in the above embodiment, and the flat plate-shaped resin portion 45 is sandwiched at the positions of the contacted portions 43 in the above embodiment. As described above, a pair of flat plate-shaped conductive portions 51 located on both sides of the resin portion 45 in the width direction may be arranged. In other words, the pair of contacted portions 43 of the mating housing 40 are arranged on the outer side of the pair of abutting portions 36 of the terminal 30 in the width direction, and the mating side terminals are arranged on the inner side of the pair of contact portions 35 of the terminal 30 in the width direction. A pair of 50 conductive portions 51 may be arranged.

In this case, in a state where the terminals 30 are not elastically deformed, the distance C between the outer end faces in the width direction of the pair of contact portions 36 is larger than the distance D between the inner wall surfaces in the width direction of the pair of contacted portions 43. (C> D), and the distance B between the inner end faces in the width direction of the pair of contact portions 35 is set to be equal to or greater than the distance A between the outer end faces in the width direction of the pair of conductive portions 51 (B ≧ A). In addition, in FIG. 4, the same reference numerals as those attached in FIG. 3 are attached to the configurations corresponding to the respective configurations shown in FIG.

In this case, as shown in FIG. 4B, the distance C between the pair of contact portions 36 is narrowed by the pair of contacted portions 43, so that the distance B between the pair of contact portions 35 becomes smaller. The pair of contact portions 35 press and contact the outer end faces of the pair of conductive portions 51 in the width direction. Even with the configuration shown in FIG. 4, the same actions and effects as those of the above embodiment shown in FIG. 3 can be achieved.

Further, in the above embodiment, the terminal 30 has a pair of contact portions 35, a pair of contact portions 36, and a pair of connecting portions 37, and the mating terminal 50 has a pair of conductive portions 51. On the other hand, the terminal 30 has a single contact portion 35 located on one side in the width direction, a single contact portion 36, and a single connecting portion 37, and the mating terminal 50 is on one side in the width direction. It may have a single conductive portion 51 located at. Also in this case, when the terminal 30 and the mating terminal 50 are assembled, the contact portion 36 abuts on the contacted portion 43 and is displaced so as to approach the conductive portion 51, and the contact portion 35 approaches the conductive portion 51.
