Problems solved by technology

[0003] However, the voltage of the high-voltage system of new energy vehicles has far exceeded the safe voltage of the human body. In order to prevent the operator from being injured by touching during maintenance, the high-voltage electrical connector components must have a high-voltage interlock function. Traditional electrical connectors The CPA does not have a structure that satisfies the high-voltage interlock function

Abstract

The invention discloses a novel CPA device and a connector assembly with a novel CPA device. The invention aims to solve a technical problem that a CPA in a traditional electric connector has no structure which satisfies a high voltage interlock function. The novel CPA device comprises a bar-shaped main body part which comprises an upper rectangular opening and a lower rectangular opening. Two sides of the main body part are provided with guide bars. The upper end of the inner side of the main body part is provided with a suspension lock hanging nose. The middle of the inner side of the main body part is provided with a limit boss. The upper part of the outer side of the main body part is provided with a boss I, and a transition bridging inclined plane is arranged between the boss I and the suspension lock hanging nose. By using the above technical scheme, the time-sharing switch-on and switch-off of a high voltage power supply circuit and a lower voltage signal circuit are achieved, an operation delay function is realized, and the harm to an operator by high voltage is avoided.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a connector position assurance (CPA / connector position assurance) device and a connector assembly for a connector position assurance (CPA) device in a new energy vehicle electrical connector. Background technique [0002] In traditional cars, CPA is generally installed on electrical connectors to ensure reliable mating and locking between the connectors. [0003] However, the voltage of the high-voltage system of new energy vehicles has far exceeded the safe voltage of the human body. In order to prevent the operator from being injured by touching during maintenance, the high-voltage electrical connector components must have a high-voltage interlock function. Traditional electrical connectors The CPA does not have a structure that satisfies the high-voltage interlock function. Contents of the invention [0004] The technical problem to be solved by the present invention is that the C...
