  The contact accommodating portion 31 has a rectangular tube shape having two notches 31g (see FIG. 2). The connection object insertion port 31j is located on the front end side of the contact accommodating portion 31. The contact accommodating portion 31 has a lower plate portion 31a, two side plate portions 31b, and an upper plate portion 31c. The lower plate portion 31a, the two side plate portions 31b, and the upper plate portion 31c are all rectangular. The two side plate portions 31b are connected to both side portions of the lower plate portion 31a. The two side plate portions 31b are bent substantially at right angles to the lower plate portion 31a. Each of the two side plate portions 31b is provided with a notch 31g. The notch 31g extends from the connection object insertion port 31j to the rear of the connecting portion 21i of the contact 2 (see FIG. 4). The notch 31g provided in one side plate portion 31b and the notch 31g provided in the other side plate portion 31b face each other in the left-right direction DL (see FIG. 2) of the connector 1. In this embodiment, the left-right direction DL and the width direction of the contact accommodating portion 31 coincide (see FIG. 2). The rear end of the notch 31g is located behind the first contact portion 22 as shown in FIG. The upper plate portion 31c is substantially parallel to the lower plate portion 31a. At the center of the upper plate portion 31c, there is a seam 31k extending in the insertion direction DI (direction in which the first bus bar 51 is inserted into the contact accommodating portion 31 of the connector 1) as shown in FIG. Both side portions of the upper plate portion 31c are connected to the upper ends of the two side plate portions 31b, respectively.

  The side plate portion 31b is provided with a protruding portion (first limiting portion) 31e (see FIG. 2). The protruding portion 31 e is bent so as to protrude into the contact accommodating portion 31. The protrusion 31e is located on the rear end side of the notch 31g.

  A protruding portion (second limiting portion) 31h is provided at the front end of the lower plate portion 31a (see FIG. 4). The protruding portion 31h is bent so as to protrude into the connection object insertion port 31j.

  Two projecting portions (second restricting portions) 31i are provided at the front end of the upper plate portion 31c (see FIG. 4). The two protruding portions 31i are bent so as to protrude into the connection object insertion port 31j.

  The cross-sectional shape of the connection part 32 is substantially U-shaped. The connecting portion 32 has a flat plate portion 32a and two side plate portions 33 connected to both sides of the flat plate portion 32a. The front end of the flat plate portion 32 a is continuous with the lower plate portion 31 a of the contact accommodating portion 31. The flat plate portion 32a is provided with a bolt through hole 32b through which the bolt 53 is passed. A second bus bar 52 is connected to the flat plate portion 32a by a bolt 53 and a nut 54 (see FIGS. 3 and 4). The two side plate portions 33 are bent at substantially right angles to the flat plate portion 32a. The front ends of the two side plate portions 33 are respectively connected to the two side plate portions 31 b of the contact accommodating portion 31.

  In order to assemble the contact 2 to the conductive holder 3, the contact 2 may be inserted into the contact accommodating portion 31 of the conductive holder 3 along the insertion direction DI of the first bus bar 51 as shown in FIG. 2.

  The distance between the second contact part 23 a 1 on the one side and the second contact part 23 a 2 on the other side of the contact 2 is larger than the distance between the protruding part 31 h and the protruding part 31 i of the contact accommodating part 31 of the conductive holder 3. However, when the contact 2 is inserted into the contact accommodating portion 31 of the conductive holder 3, the one side second spring portion 23 b 1 and the other side second spring portion 23 b 2 of the contact 2 are caused by the protruding portions 31 h and 31 i of the conductive holder 3. Since the contact 2 is compressed by being pushed, the contact 2 can pass through the connection object insertion port 31j.

  When the contact 2 passes through the connection object insertion port 31j and is accommodated in the contact accommodating portion 31 of the conductive holder 3, the contact 2 is compressed in the vertical direction DU. The contact portion 23a1 and the other second contact portion 23a2 are in contact with the lower plate portion 31a and the upper plate portion 31c of the contact accommodating portion 31, respectively. The contact 2 accommodated in the contact accommodating portion 31 can swing. In this embodiment, the contact 2 can move slightly in the front-rear direction parallel to the insertion direction DI and can rotate about an axis parallel to the left-right direction DL (see FIG. 7).

  As shown in FIGS. 3, 4, 5, and 6, the first bus bar 51 is electrically connected to the second bus bar 52 connected to the conductive holder 3 of the connector 1 by a bolt 53 and a nut 54. The first bus bar 51 may be inserted from the front of the connector 1 into the contact accommodating portion 31 of the conductive holder 3 (at this time, as shown in FIGS. 5 and 6, the longitudinal direction of the first bus bar 51 and the insertion direction DI). Is parallel.)

  At this time, the contact 2 tries to move in the insertion direction DI from the contact accommodating portion 31 of the conductive holder 3 together with the first bus bar 51. However, since the connecting portion 21i of the contact 2 hits the protruding portion 31e, the contact 2 becomes conductive. It cannot be removed from the contact accommodating portion 31 of the holder 3.

  The first bus bar 51 inserted into the receiving portion 21 of the contact 2 is supported in a state sandwiched between the first contact portion 22a1 on the one side and the first contact portion 22a2 on the other side, and via the contact 2 and the conductive holder 3 The first bus bar 51 is electrically connected to the second bus bar 52.

  When the first bus bar 51 is pulled out from the connector 1, the contact 2 tries to move together with the first bus bar 51 from the contact accommodating portion 31 of the conductive holder 3 in the direction opposite to the insertion direction DI, but the second contact portion 23 of the contact 2. Contacts with at least one of the projecting portions 31 h and 31 i of the conductive holder 3, so that the contact 2 does not come out of the contact accommodating portion 31 of the conductive holder 3.

  As shown in FIG. 7, the first bus bar 51 receives the contact 2 in a state where the position of the first bus bar 51 with respect to the connector 1 is shifted downward from the standard position (the position of the first bus bar 51 shown in FIG. 6). When inserted in the portion 21, the first contact portion 22 a 1 on one side of the contact 2 is pushed by the first bus bar 51, and the contact 2 rotates in the contact accommodating portion 31. As a result, the displacement of the first bus bar 51 is absorbed, and the first contact portion 22a2 on the other side reliably contacts the first bus bar 51, as in the case where there is no displacement of the first bus bar 51 in the vertical direction DU. The first spring portion 22b1 on the one side does not plastically deform, and the first contact portion 22a1 on the first side reliably contacts the first bus bar 51.

  As described above, the first bus bar 51 was inserted into the connector 1 with the longitudinal direction of the first bus bar 51 parallel to the insertion direction DI of the first bus bar 51 (see FIGS. 3 and 5). However, in this embodiment, since the notch 31g is provided in the side plate portion 31b of the conductive holder 3, the longitudinal direction of the first bus bar 51 is orthogonal to the insertion direction DI, as shown in FIGS. In this state, the first bus bar 51 can be inserted into the connector 1.

  According to this embodiment, even if the first bus bar 51 is displaced in the vertical direction DU with respect to the connector 1, the contact 2 swings and the positional deviation of the first bus bar 51 is absorbed, and the contact 2 and the first bus bar 51 Since the number of contact points with 51 does not decrease, the energization current value does not decrease.

  In addition, since the connector 1 is configured by one contact 2 having a plurality of first contact portions 22a1 on the one side, a plurality of first contact portions 22a2 on the other side, and one conductive holder 3 that accommodates the contacts 2. The number of parts of the connector 1 is small, and management of the parts of the connector 1 and assembly of the connector 1 are easy.

  Furthermore, since the notch 31g is provided in the side plate portion 31b of the conductive holder 3, the first bus bar 51 is in a state where the longitudinal direction of the first bus bar 51 is orthogonal to the insertion direction DI as shown in FIGS. 51 can also be inserted into the connector 1. Therefore, for example, there is no space in front of the connector 1 for inserting the first bus bar 51 into the connector 1 in a state where the longitudinal direction of the first bus bar 51 is parallel to the insertion direction DI (the state shown in FIGS. 3 and 5). Even in this case, the first bus bar 51 can be inserted into the connector 1.

  Next, a connector 201 according to a second embodiment of the present invention will be described with reference to FIGS.

  Portions common to the first embodiment are denoted by the same reference numerals and description thereof is omitted. Only the main differences from the first embodiment will be described below.

  In the connector 201 of the second embodiment, a protruding portion (second limiting portion) 231h is connected to the front end of the lower plate portion 231a of the contact accommodating portion 231 of the conductive holder 203.

  Two projecting portions (second limiting portions) 231 i are connected to the front end of the upper plate portion 231 c of the contact accommodating portion 231.

  The protrusions 231h and 231i extend along the insertion direction DI before the contact 2 is inserted into the contact accommodating portion 231 (see FIGS. 11 and 12).

  The two side plate portions 231b of the contact accommodating portion 231 are provided with a notch 231g, a hole 31d, and a protruding portion 31e (first limiting portion). The notch 231g extends rearward from the first contact portion 22 of the contact 2 from the connection object insertion port 31j. The hole 31d is located closer to the connecting portion 32 than the notch 231g. The protrusion 31e is located at the rear end of the hole 31d. The protruding portion 31 e is bent so as to protrude into the contact accommodating portion 31.

  In order to attach the contact 2 to the conductive holder 203, first, the contact 2 is inserted into the contact accommodating portion 231 of the conductive holder 203 (see FIG. 12).

  Next, the protrusions 231h and 231i are bent so that the protrusions 231h and 231i protrude into the connection object insertion port 31j (see FIG. 13).

  As shown in FIG. 14, when the first bus bar 51 is inserted into the connector 201, the first bus bar 51 is sandwiched between the one side first contact part 22 a 1 and the other side first contact part 22 a 2 of the first contact part 22. The first bus bar 51 is electrically connected to the second bus bar 52 through the conductive holder 203. When the first bus bar 51 is inserted into the connector 201, the contact 2 tries to move together with the first bus bar 51 from the contact accommodating portion 231 of the conductive holder 3 in the insertion direction DI, but the connecting portion 21i of the contact 2 is the protruding portion 31e. The contact 2 does not come out of the contact accommodating portion 231 of the conductive holder 203.

  When the first bus bar 51 is pulled out from the connector 201, the contact 2 tries to move in the direction opposite to the insertion direction DI together with the first bus bar 51, but the first contact portion 22 of the contact 2 is at least one of the projecting portions 231h and 231i. Since it strikes, the movement of the contact 2 is limited.

  In the first embodiment, when the contact 2 is inserted into the contact accommodating portion 31 of the conductive holder 3, the contact 2 is compressed by the protruding portions 31h and 31i of the conductive holder 3, and thus the protruding amount of the protruding portions 31h and 31i. If is increased, the contact 2 may be plastically deformed. On the other hand, in the second embodiment, the protruding portions 231h and 231i are bent after the contact 2 is inserted into the contact accommodating portion 231, so that when the contact 2 is inserted into the contact accommodating portion 231, the protruding portions 231h and 231i The contact 2 is not compressed excessively. Therefore, the protruding amount of the protruding portions 231h and 231i can be made larger than that in the first embodiment, and the contact 2 can be more reliably prevented from coming off from the contact accommodating portion 231.

  Next, the connector 301 of 3rd Embodiment of this invention is demonstrated based on FIGS. 15-25.

  Portions common to the first embodiment are denoted by the same reference numerals and description thereof is omitted. Only the main differences from the first embodiment will be described below.

  As shown in FIGS. 15 and 16, the contact 302 has a receiving portion 321, a first contact portion 322, and a second contact portion 323. The contact 302 is formed by punching and bending a metal plate having conductivity and elasticity.
