Description

[Detailed Description of the Invention] The present invention relates to an improvement of an electrical component terminal connection portion of a junction box in which electrical component terminals such as fuse terminals and relay terminals are connected to busbar conductors arranged in the junction box.

Wire harnesses in which a large number of electric wires are bundled are used for wiring in automobiles, and junction boxes are used in the middle of the wire harnesses to facilitate branching of electric wires, installation of fuses, etc. As shown in Figure 1, the junction box consists of a box 3' which is divided into two parts, consisting of a lower cover 1' and an upper cover 2', and a plurality of busbar conductors 5' arranged in multiple layers with an insulating plate 4' in between. be.
Conventionally, since the busbar conductor 5' disposed in the junction box 3' does not have a terminal receiving part, a connecting terminal 9' having terminal receiving parts 7' and 8' at both ends is used.
The end of the bus bar conductor 5' is connected to one terminal receiving part 8' of the connecting terminal 9', and the fuse terminal 6' is connected to the other terminal receiving part 7'. However, if you use the connecting terminal 9' that has terminal receivers at both ends like this,
There were problems such as the length of the connecting portion being longer and the number of connecting portions being in two locations, making contact failure more likely.

The present invention was developed in view of the above problems, and is an electrical connection box that can shorten the connection part, be electrically good, and extremely easily connect electrical component terminals such as fuse terminals and relay terminals to busbar conductors. It provides a component terminal connection section.

Next, this will be explained in more detail based on the drawings. Figures 2 to 4 show connection parts of electrical component terminals such as fuse terminals according to the present invention, in which a fuse 11 is connected to a pair of fuse terminals 12, 1.
2 are connected by a dissolvable piece 13, and the dissolvable piece 13 is covered with a plastic 14.
The terminal 12 of this fuse 11 is connected to the busbar conductor 15
The overlapping portion 16 is pressed and connected by a plate-shaped elastic connector 17.

In the plate-like elastic connection body 17, both side edge ranges of the plate are curved in a C-shape, and the distance between the side edges and one side of the plate is initially equal to the thickness of the busbar conductor 15 and the fuse 11, which is an electrical component. The overlapping portion 16 of the terminal 12 and the bus bar conductor 15 is set to be smaller than the sum of the thickness of the terminal 12, and the overlapping portion 16 of the terminal 12 and the bus bar conductor 15 is
7 and one side of the plate, and the two are pressed together by the elastic force generated by the deformation of the C-shaped curved portion. Therefore, the overlapping portion 16 becomes a good connection portion with low electrical resistance.

Note that the shape of the elastic connector 17 and the shapes of electrical components such as fuses and relays are not limited to those in the embodiment.

As explained above, according to the present invention, since electrical component terminals such as fuse terminals and relay terminals and busbar conductors are overlapped, the length of the connection part can be shortened, and the overlapped part is pressed and connected with an elastic connector. The electrical contact at the overlapped portion is good, contact failures are less likely to occur, and furthermore, the work of attaching and detaching electrical component terminals is extremely easy, and there are practical effects such as extremely low cost.
