Problems solved by technology

However, due to changes in the use environment and application fields, the size and shape of the pole will need to be changed accordingly, which requires separate mold making, which will increase the cost to a certain extent, and will also affect the progress of research and development
In addition, the poles on the battery pack are generally in direct contact with the outside air. After a certain period of time, accidents such as short circuit, leakage or poor contact are prone to occur when the pole is connected to the load, which will affect the normal use of the battery pack.

Embodiment 1

[0021] A connecting part used to connect the battery pack with the load, such as figure 1 , figure 2 As shown, it includes a non-metallic fixed seat 1, a conductive pole 2, a fixed plate 3, a terminal 4, a connecting piece 5, an anti-loosening structural member 6 and a protective cover 7, and the connecting piece 5 of this embodiment is a connecting copper bar; As shown in Fig. 3 (a) and Fig. 3 (b), a groove 101 is provided on one side of the non-metallic fixed seat 1, and a through hole 102 is provided at the bottom of the groove 101, and a through hole 102 is formed on the other side of the non-metallic fixed seat 1. Two half-moon-shaped blocks 103 are arranged symmetrically to the center and a gap 104 is left between the two blocks 103. The height of the blocks 103 of the non-metallic fixed seat 1 is not less than 1.5 times the thickness of the first nut 10, There are stud perforations 105 on the four corners of the non-metallic fixing seat 1; Figure 4 As shown, the con...

Embodiment 2

[0025] A connecting part for connecting the battery pack and the load, its structure is similar to the structure of the connecting part for connecting the battery pack and the load in embodiment 1, the difference is that: the back of the fixing plate (that is, facing away from the non-metallic One side of the fixed seat) is provided with a rivet nut, and the non-metallic fixed seat passes through the stud holes on the non-metallic fixed seat in turn, the threaded hole on the fixed plate, and then cooperates with the rivet nut to lock and fix it. On the fixed plate; the body of the anti-loosening structural part is set on the position where the conductive pole is located between the connecting piece and the first nut through the round hole, and the first baffle plate of the anti-loosening structural part is connected with the outer side of the connecting piece and the second nut in turn. The second baffle plate of the anti-loosening structural member contacts the outer surface o...

Abstract

The invention provides a connecting component for communicating a battery pack with a load, which comprises a non-metal fixing seat, a conducting pole, a fixing plate, a wiring terminal and a connecting sheet, wherein the non-metal fixing seat is fixed on the fixing plate, two check blocks of the non-metal fixing seat penetrate through a through hole of the fixing plate in a matched manner, the lower end of the conducting pole penetrates through a through hole of the non-metal fixing seat in a matched manner, a supporting nut of the conducting pole is clamped in a groove of the non-metal fixing seat in a matched manner, one end of the wiring terminal is fixed and sleeved at the upper end of the conducting pole, one end of the connecting sheet is fixedly sleeved at the lower end of the conducting pole, and the other end of the connecting sheet penetrate through a gap reserved between the two check blocks of the non-metal fixing seat. The connecting component for communicating the battery pack with the load has the advantages of simple and compact structure and high use safety and reliability.

Description

technical field [0001] The invention relates to a connecting part for connecting a battery pack and a load. Background technique [0002] When the battery pack (including the battery box and the battery module) is in use, it is generally connected to the load through poles, and the electric energy of the battery pack is transmitted to the load through the poles. At present, when most battery packs are manufactured, the general positive terminal and the total negative terminal are directly connected to the poles on the shell. The poles are the components for power transmission, and the connection reliability and safety are very high. important. However, due to changes in the use environment and application fields, the size and shape of the pole will need to be changed accordingly, which requires separate mold making, which will increase the cost to a certain extent, and will also affect the progress of research and development. In addition, the poles on the battery pack are...
