Description

Technical Field

[0001] The utility model relates to the technical field of power supply, in particular to a connection device. Background Art

[0002] With the popularization of new energy battery technology, power batteries have been widely used. The supply of power batteries in the form of battery modules has become a development trend in the industry. At present, the charging and discharging test is generally carried out by directly connecting the integrated test cabinet to the battery module. Before the test, the conductive terminal of the positive wiring harness of a battery module needs to be stacked with the conductive terminals of the positive wiring harness of two test cabinets and fixed by screws and nuts. Then, the connection of the three conductive terminals is covered with insulating tape. The negative wiring harness of the battery module is also processed in the same way before the charging and discharging test of the battery module is started.

[0003] There are several problems with this method: First, when using insulating tape to cover the connection between the three conductive terminals, due to the relatively thin thickness of the tape and the direct tightening of the conductive terminals with screws and nuts, it is easy for the conductive parts of the conductive terminals to have high voltage, small contact area, and large resistance, resulting in a small overcurrent capacity, which in turn causes the local temperature to be too high, thereby burning the wiring harness and tape, posing a safety hazard; second, the total positive and negative conductive terminals wrapped with insulating tape are placed directly on the floor or plastic pallet. At this time, the total positive conductive terminal and the total negative conductive terminal are easy to contact and cause a short circuit, and if the staff accidentally touches them, there will be a risk of electric shock. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a docking device, including:

[0005] An insulating box body, one side of which is provided with a first through hole and a second through hole, and an opposite side of the insulating box body is further provided with a third through hole and a fourth through hole;

[0006] A partition, dividing the insulating box into a first space and a second space, the first through hole and the second through hole are respectively located on both sides of the partition, the third through hole and the fourth through hole are respectively located on both sides of the partition, the first through hole and the third through hole are in the first space, and the second through hole and the fourth through hole are in the second space;

[0007] A conductive brass block is fixed at the bottom of the insulating box, and includes a first conductive brass block and a second conductive brass block. The first conductive brass block is fixed in the first space, and the second conductive brass block is fixed in the second space. The first conductive brass block is provided with a first screw hole and a third screw hole, and at least two of the first screw holes correspond to the positions of the first through holes respectively, and the third screw hole is located between the two first screw holes and corresponds to the position of the third through hole. The second conductive brass block is provided with a second screw hole and a fourth screw hole, and at least two of the second screw holes correspond to the positions of the second through holes respectively, and the fourth screw hole is located between the two second screw holes and corresponds to the position of the fourth through hole.

[0008] Furthermore, there are at least two first through holes, which respectively correspond to the positions of the two first screw holes.

[0009] Furthermore, there are at least two second through holes, which respectively correspond to the positions of the two second screw holes.

[0010] Furthermore, there is at least one third through hole and at least one fourth through hole.

[0011] Furthermore, two ends of the conductive brass block are fixed to the bottom of the insulating box by screwing.

[0012] Furthermore, it also includes an insulating box cover, which is hinged to the insulating box body.

[0013] Furthermore, the insulating box body and the insulating box cover are both made of bakelite.

[0014] Furthermore, the insulating box body and the insulating box cover are both made of polybutylene terephthalate.

[0015] Furthermore, the insulating box body and the insulating box cover are both made of polycarbonate or polyvinyl chloride.

[0016] Furthermore, positive and negative pole markings are provided on the insulating box cover.

[0017] The beneficial effect is that, unlike the prior art, the present application can separately fix all the conductive terminals on the conductive brass block without stacking them together, thereby increasing the contact area at the bottom of the conductive terminal, reducing resistance, improving the current carrying capacity, and avoiding local excessive temperature that may cause the wiring harness to burn out; in addition, the insulating box is divided into a first space and a second space by a partition, and the positive wiring harness conductive terminals of the two test cabinets and the positive wiring harness conductive terminals of the battery module are fixed on the first conductive brass block in the first space, and the negative wiring harness conductive terminals of the two test cabinets and the negative wiring harness conductive terminals of the battery module are fixed on the second conductive brass block in the second space. In this way, the total positive conductive terminal and the total negative conductive terminal are separated in two spaces so that the two will not easily contact each other, thereby avoiding short circuits. At the same time, it also avoids the operator from touching the conductive terminals and causing the risk of electric shock, thereby eliminating safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS
