detailed description

The bus bar, connection assembly and electrical box of the present invention will be described in detail below in conjunction with the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only illustrative illustrations of the present utility model, and are not intended to limit it in any way. Throughout the drawings, the same reference numerals designate the same or similar parts.

Referring to Fig. 1, a bus bar 100 provided for the utility model, the bus bar 100 includes a main body 101 and a connecting terminal 105, the main body has a length direction, and two side edges 110 and 112 are provided in the length direction, The connection terminal 105 extends laterally from the side edge 112 of the main body. There is at least one connection terminal 105 for connecting with at least one electrical component. The electrical component may be a relay and/or a fuse. A plurality of connection terminals are shown in FIG. 1 105. The other side edge 110 of the main body 101 extends straight along the length direction of the main body 101 , and is used for inserting into the mating terminal 207 . In order to match the bus bar 100 with the mating terminal 207 , the edge 110 on the other side of the bus bar 100 is provided with a chamfer 120 , and the chamfer 120 can be processed into a rounded edge. The chamfer 120 may be continuous in the length direction of the bus bar 100 .

The bus bar 100 in Fig. 1 is compared with the bus bar with protrusions in the prior art, the width of the main body 101 of the bus bar 100 is greater than the width of the bus bar main body in the prior art, therefore, the mating terminal 207 with both ends open It can be directly inserted on the main body 101 of the bus bar 100 . Since the width of the main body of the bus bar in the prior art is usually smaller than the depth of the opening of the mating terminal, when the mating terminal is mated with the bus bar, it needs to be inserted on the protruding portion of the bus bar. When processing a busbar with protrusions in the prior art, part of the material needs to be cut off from the entire plate-shaped metal material to form the protrusions, and the width of the protrusions matches the opening depth of the mating terminal. Part of the cut material is not used, causing waste and increasing the process. When processing the busbar 100, the main body 101 does not need to cut part of the material, which reduces the cutting process steps, and the main body 101 can be used as a male terminal to cooperate with the mating terminal 207, so that the position setting of the mating terminal 207 is more flexible and more flexible. Easily adaptable to positional arrangements in electrical boxes. And multiple mating terminals can be inserted at the same time, increasing the flexibility of use.

Referring to Fig. 1B, another busbar 100' provided for the utility model, the other side edge 110' of the main body 101 of the busbar 100' has multiple chamfers 121, which is different from the busbar in Fig. 1A, because the chamfer The part 121 is processed by a stamping process. According to the requirements of the stamping process, the chamfered part 121 can only be punched locally, that is, the chamfered part 121 can be discontinuous in the length direction, so that the gap between the two chamfered parts 121.1 and the chamfered part 121.2 There may be another side edge portion 130 between them, wherein the other side edge portion 130 may maintain a sharp cut edge, while the chamfered portion 121 may have a rounded edge to facilitate insertion. It is sufficient that the width of the chamfer 121 is not less than the width of the mating terminal. If continuous punching is performed on the bus bar, multiple chamfers 121 can be made on the bus bar, and the punching process will form multiple edge portions 130 on the other side that are not punched and retain sharp cutting edges. Using the stamping process to continuously stamp the busbar can speed up the processing efficiency of the chamfered portion 121 and realize automatic processing. In addition, the width of the chamfered portion 121 can be adjusted according to requirements, so as to facilitate the customization of bus bars with different requirements, and to match different mating terminals.
