Abstract

The invention discloses a contact pin assembly capable of achieving direct-current charging interface replacement. The contact pin assembly comprises a contact pin matrix, an elastic contact part, an insulation cap and a sleeve; the sleeve is arranged at the head of the contact pin matrix in a sleeving mode and locked through a locking part, and the elastic contact part is arranged between the head of the contact pin matrix and the sleeve in a sleeving mode, so that the sleeve and the contact pin matrix are in elastic contact for conduction. The insulation cap is fixed to the head of the contact pin matrix through a locking part. The sleeve in the contact pin assembly can be replaced and can be independently replaced after being abraded, and a whole direct-current charging gun wiring harness does not need to be replaced. Besides, when the sleeve is abraded, the sleeve can be replaced by taking down and re-locking the locking part, and operation is convenient and fast. Besides, the locking force of the elastic contact part guarantees the structural strength and can provide continuous positive pressure for end face contact of the contact pin matrix and the sleeve, and the overcurrent capacity of the contact pin assembly is guaranteed.

Description

technical field [0001] The invention relates to a replaceable pin assembly of a DC charging interface. Background technique [0002] The DC charging gun made according to GB / T11918-2015 has only one charging mode, which is installed on a fixed charging pile. At present, the number of charging piles is far lower than the sales volume of new energy vehicles. This has caused the phenomenon that the supply of charging facilities is in short supply, and it also makes the DC charging guns exist in the state of overload and high-intensity use for a long time, which is easy to cause wear and tear on the internal pins. If the pins of the traditional DC charging gun are worn out, the entire wiring harness of the charging gun needs to be bent and replaced, which is very troublesome. And waste resources. Contents of the invention [0003] The purpose of the present invention is to provide a replaceable pin assembly of a DC charging interface to solve the problem that the entire wiri...
