Description

This disclosure relates to a terminal block.

A terminal block to which multiple fastening members are fastened is disclosed, for example, in Patent Document 1. The terminal block disclosed in Patent Document 1 includes multiple bus bars. The multiple bus bars are fastened to the fastening members by bolts.

JP 2020-18065 A

The bus bar is fastened to a plurality of fastened members, for example a first fastened member and a second fastened member. In this case, if the first fastened member is fastened to the bus bar while the bus bar is fastened to the second fastened member, metal powder generated when fastening the first fastened member may adhere to the second fastened member and cause a short circuit within the second fastened member.

The terminal block that solves the above problem is a terminal block that includes a resin part and a bus bar integrated with the resin part, the bus bar includes a first fastening part to which a first fastened member is fastened, a second fastening part to which a second fastened member is fastened, a connecting part that connects the first fastening part and the second fastening part, and a standing part that is provided between the first fastening part and the second fastening part and stands up from the connecting part, and the resin part includes a standing resin part provided on the standing part.

A standing portion and a standing resin portion are provided between the first fastening portion and the second fastening portion. Even if metal powder is generated when fastening the first fastening member to the first fastening portion, the metal powder can be prevented from moving beyond the standing portion and the standing resin portion. This can prevent the metal powder from reaching the second fastening member. This can prevent the metal powder from adhering to the second fastening member, and can prevent the occurrence of a short circuit within the second fastening member.

In the above terminal block, the standing portion may include a third fastening portion to which a third fastened member is fastened.
The terminal block may further include a housing, the housing having an opening provided in correspondence with the first fastening portion.

This disclosure makes it possible to prevent short circuits from occurring.

(2) The standing portion 65 is part of the negative bus bar 60. A part of the negative bus bar 60 can also be used as a member for preventing metal powder from reaching the second negative fastening portion 84.

(3) Providing the standing portion 65 can reinforce the strength of the standing resin portion 102. Compared to a case where only the standing resin portion 102 is used as a member for preventing metal powder from reaching the second negative electrode fastening portion 84, the strength of the standing resin portion 102 can be improved.

(4) The standing resin portion 102 is provided so as to cover the standing portion 65. When performing fastening work, contact between the fastening members B1, B2, B3, B4 and tools and the standing portion 65 can be suppressed. Generation of metal powder from the standing portion 65 can be suppressed.

(5) The standing portion 65 includes a fourth negative electrode fastening portion 94. By providing the fourth negative electrode fastening portion 94 to the standing portion 65, the thickness direction of the first negative electrode fastening portion 61 and the thickness direction of the fourth negative electrode fastening portion 94 are different. In other words, the direction in which the fastening members B1 and B4 are fastened is different between the first negative electrode fastening portion 61 and the fourth negative electrode fastening portion 94. Due to the shape of the fourth positive electrode connecting member 161 and the fourth negative electrode connecting member 162, and the constraints on the arrangement of the terminal block main body 21 and the fourth connecting member 160, it may be necessary to fasten the fastening member B4 from a direction perpendicular to the thickness direction of the first negative electrode fastening portion 61. Even in such a case, by providing the fourth negative electrode fastening portion 94 to the standing portion 65, the fourth connecting member 160 and the terminal block 20 can be connected.

(6) The housing 22 has openings 23, 24. Because the fastening work is performed through the openings 23, 24, it is difficult to visually confirm that metal powder has been generated. As a result, it is difficult to recognize that metal powder has been generated, and there are cases in which the metal powder cannot be removed from the housing 22. Even in such a case, it is possible to prevent the metal powder from reaching the second connecting member 140.

The embodiment can be modified as follows: The embodiment and the following modified examples can be combined with each other to the extent that there is no technical contradiction.
The terminal block 20 only needs to include the terminal block body 21 and does not necessarily have to include the housing 22 .

The standing portion 65 does not necessarily have to include the fourth negative electrode connecting portion 93 and the fourth negative electrode fastening portion 94 .
The standing portion 65 may be provided at least between the first negative electrode fastening portion 61 and the second negative electrode fastening portion 84 .

The entire body 66 may be covered by the standing resin portion 102 .
The negative bus bar 60 may include at least the first negative fastening portion 61 , the first negative connecting portion 64 , the standing portion 65 , the second negative connecting portion 80 , and the second negative fastening portion 84 .

The positive bus bar 30 may have an upright portion. In this case, the upright portion is provided between the first positive fastening portion 31 and the third positive fastening portion 41 and the second positive fastening portion 35.
As shown in Fig. 5, the standing portion 65 may be provided in at least a part of the standing resin portion 201. In the example shown in Fig. 5, the standing resin portion 201 is a rectangular plate. The standing portion 65 includes a first wall portion 202 and a second wall portion 203. The first wall portion 202 and the second wall portion 203 are provided at both ends of the long side direction of the standing resin portion 201 with a space therebetween. The standing portion 65 is not provided between the first wall portion 202 and the second wall portion 203. It can be said that the standing portion 65 is not provided between the first wall portion 202 and the second wall portion 203 of the standing resin portion 201.
