Problems solved by technology

[0002] At present, the new energy vehicle industry is developing rapidly, and the sales volume of new energy vehicles has doubled, but the supply of charging piles matching it is in short supply, which leads to the high-frequency and high-intensity use of the DC charging guns on the DC charging piles; The DC charging gun may reach the designed number of uses in a relatively short period of time. At this time, the entire DC charging gun wiring harness needs to be replaced, which is troublesome and wasteful; a small number of charging guns with replaceable pins have low connection reliability and current The problem of low transmission efficiency

Abstract

The invention discloses a replaceable contact pin assembly used for a direct current charging interface. The replaceable contact pin assembly comprises a contact pin base body and a conductive part, wherein a cable is crimped at the tail part of the contact pin base body and the contact pin base body is fixed in a direct current charging gun; the conductive part is in contact with a socket jack for electric conduction; a screw thread structure is tapped in the interior of the conductive part and at one end of the contact pin base body separately, and the interior of the conductive part and one end of the contact pin base body are connected through screw threads; the screw thread part of the conductive part is sleeved with an anti-loosening elastic cushion in a penetration manner; at least one elastic contact part which is matched with and in contact with the outer wall of the conductive part is arranged on the head of the contact pin base body; and the elastic contact part adopts an annular spring structure. The replaceable contact pin assembly used for the direct current charging interface is creative in structure; when it is found that the contact pin originally matched with the charging gun in worn out, the contact pin can be replaced directly in a convenient and rapid manner; and in addition, the replaceable contact pin assembly is reliable in connection and relatively high in current transmission efficiency.

Description

technical field [0001] The invention relates to the field of connectors, in particular to a replaceable pin assembly for a DC charging interface. Background technique [0002] At present, the new energy vehicle industry is developing rapidly, and the sales volume of new energy vehicles has doubled, but the supply of charging piles matching it is in short supply, which leads to the high-frequency and high-intensity use of the DC charging guns on the DC charging piles; The DC charging gun may reach the designed number of uses in a relatively short period of time. At this time, the entire DC charging gun wiring harness needs to be replaced, which is troublesome and wasteful; a small number of charging guns with replaceable pins have low connection reliability and current The problem of low transmission efficiency. Contents of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the replaceable pin assembly for the DC charging interface provide...
