Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a CPA functional connector. Background Art

[0002] Connectors are a component that electronic engineering technicians often come into contact with. They are used to achieve current flow between blocked or isolated circuits in a circuit, so that the circuit can achieve the predetermined function. Since the connector needs to be used continuously for a long time after being connected, and even needs to be moved as a whole, the stability of the connector after being connected has received more and more attention. The connector generally plugs the two terminals into the male and female sheaths respectively, and fixes the two sheaths to achieve the electrical connection of the two terminals. In order to achieve the stability of the two sheaths after connection and prevent the two from separating, a CPA piece for fixing the other is generally slidably set on one of the sheaths. CPA, or connector position assurance, refers to a connector positioning device, a secondary lock for connector positioning. Therefore, it is necessary to escape the material on the sheath to provide a plug-in and unplug space for the CPA piece, but escaping the material on the plastic will cause the strength of the sheath to deteriorate. With the gradual expansion of the application field of connectors, in some occasions, higher requirements are put forward for the stability and installation convenience of the connector. Therefore, it is urgent to design a connector assembly with simple structure, convenient installation and strong stability.

[0003] Chinese patent CN117374665A invention discloses a connector assembly with CPA function, including a CPA part and a male connector and a female connector that are plugged in and matched. The male connector includes a male sleeve and a male terminal, and the female connector includes a female sleeve and a female terminal. The present invention respectively arranges a hanging part and a hanging ear that match each other on the male sleeve and the female sleeve to achieve a primary locking of the male sleeve and the female sleeve, and then achieves a secondary locking of the male sleeve and the female sleeve through a CPA part that is detachably arranged on the hanging part. Since the CPA part is arranged on the hanging part, there is no need to escape material on the male and female sleeves to provide a plug-in space for the CPA part. Therefore, the strength of the connector assembly can be significantly increased, and it has the advantages of strong stability, etc. At the same time, the hanging part is rotatably connected to the male sleeve through an ear plate structure, and the locking and unlocking of the secondary lock structure can be achieved by rotating the hanging part, which has the advantages of simple structure and convenient installation, etc. However, the invention cannot fix the connector in all directions to prevent movement, and the fixed lock is easy to fall off and be lost, and it cannot provide multi-length protection for the wire access point, so it needs to be improved.
