Example 1

The embodiment provides a busbar compression plug, and the compression plug needs to be matched with an insulating shell 1 with a clamping limiting structure for use in actual use, and is mainly used for fixing the opening of a groove 2 on the insulating shell 1 so as to limit a busbar 3 in the groove 2. As shown in fig. 1, it comprises a plug body 5, said plug body 5 comprising an upper part and a lower part. Wherein,,

clamping structures for clamping between the two side rails 11 of the insulating shell 1 are symmetrically arranged on two sides of the upper portion of the plug body 5, namely, the clamping structures are symmetrically arranged on two sides of the upper portion of the plug body 5 respectively. The clamping structure comprises an extrusion bevel edge 7, a barb portion 8 and a position avoiding concave neck 9 which are sequentially arranged from top to bottom. The extrusion bevel edge 7 is in a splayed structure on the plug body 5 and is mainly used for enabling the plug body 5 to slide into the space between the two side rails 11 of the insulating shell 1. The position avoiding concave neck 9 is a structure with two sides of the plug body 5 recessed inwards, and is mainly used for avoiding positions between the plug body 5 and the side rail 11. The reverse hook part 8 can slide into the groove 2 by pressing the bevel edge 7 and is clamped between the two side rails 11.

The upper end of the plug body 5 is provided with a plug pressing part 6 which is used for extending into the groove 2 of the insulating shell 1 to press the bus bar copper bar 3, and a downward concave position avoiding groove 14 is arranged, and the position avoiding groove 14 is correspondingly arranged according to position avoiding requirements and is used for preventing the upper end of the plug body 5 from being in contact with a middle gear on the insulating shell 1 so that the plug pressing part 6 cannot act on the bus bar copper bar 3.

Specifically, when the pressing plug portion 6 is located in the middle of the upper end of the plug body 5 and/or on two sides of the upper end of the plug body 5, the pressing plug portion 6 is separately disposed in the avoidance groove 14, the lower end of the pressing plug portion is located at the bottom of the avoidance groove 14, the upper end of the pressing plug portion extends out of the avoidance groove 14 to be used for pressing the busbar copper bar 3, and the pressing plug structure with the upper end protruding out of the avoidance groove 14 is separately disposed in the avoidance groove 14. When the plug pressing parts 6 are positioned at two sides of the upper end of the plug body 5, the upper end surfaces of the two side walls of the clearance groove 14 are the plug pressing parts 6, which is equivalent to adopting the end surfaces of the two sides of the upper part of the plug body 5 as the plug pressing parts 6 to press the bus bar copper 3. When the pressing plug part 6 is located at the middle part and two sides of the upper end of the plug body 5 at the same time, the pressing plug part 6 is a combination of the two structures.

It should be noted that, the number of the plug pressing portions 6 on the plug body 5 corresponds to the number of the grooves 2 and the bus bar copper bars 3, and when the number of the grooves 2 is one, the plug pressing portions 6 may be separately disposed in the middle of the clearance groove 14 to press the bus bar copper bars 3. When the number of the grooves 2 is two, the upper end surfaces of the two side walls of the clearance groove 14 can be used as the plug pressing parts 6 to press the bus bar copper 3. When the number of grooves 2 exceeds two, the caulking portion 6, which can be combined with the two structures described above, presses the bus bar copper 3. After the plug body 5 is clamped on the insulating shell 1, the plug pressing part 6 stretches into the groove 2 and presses the corresponding bus bar copper 3 from the thickness direction so as to prevent the bus bar copper 3 from sliding.

The lower part of the plug body 5 is provided with a blind hole 10, and the inner diameter of the blind hole 10 is sequentially increased from top to bottom. The structure can ensure that the production cost is reduced on the premise of higher structural strength of the plug body 5. Of course, this arrangement is preferred, and the lower portion of the plug body 5 may not be provided with a blind hole 10, or the blind hole 10 may be provided directly as a through hole, as desired.

In practical use, the bus bar copper 3 can be placed into the corresponding groove 2 from the opening of the groove 2, and plugs or end covers 4 can be arranged at two ends of the groove 2 to limit the bus bar copper 3 from two ends according to requirements. The inverted hook part 8 is pushed into the clamping limiting structure of the insulating shell 1 from the opening of the groove 2 through the guide of the extrusion bevel edge 7, and the plug pressing part 6 of the plug body 5 after clamping presses the bus bar 3 from the thickness direction so that the bus bar cannot move, thereby realizing the rapid assembly of the bus bar and achieving the purpose of effectively limiting the bus bar 3.
