[0032] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Embodiment 1

[0034] like Figure 1 As shown, this embodiment provides an insulating connector, including an insulating column 1, a fixing foot 2, an insert 3, and a bushing 4.

[0035] like Figure 1 , Figure 2 , Figure 3As shown, fixing feet 2 are fixed on both sides of the bottom of the insulating column 1, and reinforcing plates 5 are fixed on the front and rear sides of the intersection of the fixing feet 2 and the insulating column 1. The reinforcing plates 5 in this embodiment are triangular reinforcing ribs for increasing the strength of the fixing feet 2; a fixing hole is provided on the fixing feet 2; the insulating column 1 and the fixing feet 2 are made of PC+ABS resin or PA66+GF, and the insulating column 1 and the fixing feet 2 are integrally injection molded; a mounting hole is provided on the top of the insulating column 1, and an insert 3 is fixed in the mounting hole. The outer side of the insert 3 is injection molded in the mounting hole, and an internal threaded hole is provided on the inner side of the insert 3 for matching with the first bolt 10. The material of the insert 3 is stainless steel, and the insert 3 is 0.2-0.5mm higher than the upper plane of the insulating column 1, so that the fuse 7, the shunt 8, and the copper bus 9 are overlapped with the insert 3 when fixed to the insulating column 1 by the first bolt 10, and are not in direct contact with the upper plane of the insulating column 1. The reliability of the fixation can be improved by rigid connection; a reinforcing rib 6 is fixed at the bottom end of the insulating column 1 for increasing the strength.

[0036] like Figure 1 , Figure 2 As shown, two bushings 4 are provided, which are respectively injected into the fixing holes on the fixing feet 2 on both sides of the bottom of the insulating column 1. An inner light hole is opened on the inner side of the bushing 4, and an inner bolt and nut are fixed on the battery pack case (not shown). The insulating connector is fixed to the battery pack case by passing the second bolt 11 through the inner light hole of the bushing 4. The bushing 4 is made of stainless steel, and the bushing 4 protrudes from the upper and lower sides of the fixing feet 2 by 0.2-0.5mm. When the insulating column 1 is fixed to the battery pack case by the second bolt 11, the second bolt 11 contacts the bushing 4, and does not directly contact the upper surface of the fixing foot 2. The bushing 4 contacts the battery pack case, and the fixing foot 2 does not contact the battery pack case. The rigid connection increases the fixation reliability.

[0037] When in use, the insulating connector can be used alone or in combination. The insulating connectors can be used in combination horizontally or in combination vertically. Figure 4 , Figure 5 As shown, the two insulating connectors are combined horizontally or vertically (selected according to the space reserved on the battery pack body) to fix the fuse 7 on the battery pack body; Figure 6 , Figure 7 As shown, two insulating connectors are combined horizontally or vertically (selected according to the space reserved on the battery pack body) to fix the shunt 8 on the battery pack body; Figure 8 As shown, an insulating connector fixes multiple copper bars 9 on the battery pack box; the insulating connector can fix fuses, shunts, copper bars and other products of various specifications horizontally, vertically and diagonally, with high versatility and low cost.
