Problems solved by technology

[0004] The present invention aims to solve the technical problem that in the prior art, the electrodes of the selector of the power distribution system are in direct contact with the copper bars of the power supply or the copper bars of the charging terminal, resulting in relatively large friction, which easily leads to damage to the copper bars and power loss. , a contact finger structure is proposed, the application of this contact finger structure can buffer the contact between the selector electrode and the copper bar, reducing friction and loss

Embodiment 1

[0063] like figure 1 As shown, the contact finger structure 1 of this embodiment includes a conductor 11 and a carrier 12. The conductor 11 is provided with a contact portion 111 for overlapping with the contact copper bar, and a support arm extends on the carrier 12. The support arm A buffer portion 121 is connected. The buffer portion 121 includes an elastic cantilever 1212 and a buffer member 1211. One end of the elastic cantilever 1212 is connected to the support arm of the carrier 12, and the other end of the elastic cantilever 1212 is connected to the buffer member 1211. A part of the buffer member 1211 protrudes For the contact portion 111, when the contact portion 111 and the contact copper bar are overlapped, the protruding portion of the buffer member 1211 comes into contact with the contact copper bar before the contact portion 111. The buffer portion 121 in this embodiment is made of nylon plastic, which has high mechanical strength. , good toughness, not easy to b...

Embodiment 2

[0067] Another aspect of the present invention provides an electrical connection structure, such as figure 2 As shown, the electrical connection structure of this embodiment includes the finger structure 1 of the first embodiment and a contact pressure monitoring module. The contact pressure monitoring module includes a pressure sensing module 13, a control module and a driving module, and the pressure sensing module 13 is arranged in the buffer On the side of the part 121, the buffer part 121 is pressed to the pressure sensing module 13 when buffering, the pressure sensing module 13 sends a feedback signal to the control module, the control module controls the drive module to start and stop according to the feedback signal, and the drive module is used to drive the contact part 111. To carry out the lap joint action, specifically, the supporting body 12 in this embodiment also extends a supporting arm 131, and the supporting arm 131 is provided with a pressure sensing module ...

Embodiment 3

[0073] Another aspect of the present invention provides a channel selector, such as Figure 5-6 As shown, the channel selector 3 of the present embodiment includes the electrical connection structure of the second embodiment and the moving carrier 31. In the present embodiment, both ends of the conductive member 32 are provided with the contact finger structure 1 of the first embodiment. The finger structures 1 are respectively used to overlap with the horizontal copper bar 41 and the vertical copper bar 42. The moving carrier 31 is provided with an escape port 311 for the contact finger structure 1 at the first end and the second end of the conductive member 32 to overlap. The number of the components 32 is two, and the mobile carrier 31 in this embodiment is correspondingly provided with two sliding blocks 24 , a mobile base 26 and a deflection component respectively.

[0074] Further, the mobile carrier 31 also includes a casing 312 and a cover plate 313 , the fixing block ...

Abstract

The present invention relates to the technical field of charging equipment, and in particular to a contact finger structure, comprising a contact portion and a buffer portion, the contact portion is used to establish an electrical connection, the buffer portion is arranged on one side of the contact portion, and the At least a part of the buffer part protrudes from the contact part, and the protruding part of the buffer part overlaps before the contact part during electrical connection. The contact finger structure provided by the present invention can buffer the electrode of the channel selector and the contact copper The pressure when the bars are overlapped reduces the physical wear and electrical energy loss caused by friction to the copper bars.

Description

technical field [0001] The invention relates to the technical field of charging equipment, in particular to a contact finger structure, an electrical connection structure, a channel selector and a power distributor. Background technique [0002] With the progress of society and the enhancement of environmental protection awareness, electric vehicles have attracted more and more attention, and the charging of electric vehicles is related to the popularization and promotion of electric vehicles. In order to charge electric vehicles of different capacities, many companies have begun to study Manufacture of charge stacks for power distribution. [0003] In the existing flexible power distribution system of the charging stack, the core unit is the PDU. As the intermediate hub between the power supply and the charging terminal, the PDU plays the role of connection and distribution. However, when the selector of the PDU performs power switching, the electrodes of the selector and t...
