Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an elastic pin multi-core cable connector and a connection method. Background Art

[0002] A connector is a device used to connect electronic devices or circuits. It plays the role of transmitting signals, power or data. Connectors usually consist of a socket and a plug, and the plug is connected by inserting into the socket. Modular plug connectors are a special type of connector that has a modular design and can combine different types of plugs and sockets to meet different application requirements. Modular plug connectors can achieve reliable electrical and mechanical connections.

[0003] In the prior art, when the connector is used, it is necessary to align the pin with the slot and insert it, so that the socket and the plug are plugged together for connection. However, when the plug is inserted into the socket, it is easy for the plug to not be correctly aligned with the socket, resulting in the pin not being aligned with the slot, and the pin being mis-inserted, resulting in unstable connection. In order to solve the problems existing in the prior art, the invention with the publication number CN117996522B discloses an anti-mis-insertion and precise positioning device (hereinafter referred to as prior art 1), including a head shell and a positioning assembly, and a seat shell is arranged at the bottom of the head shell. When the present invention is used, the identification guide pin is inserted between the two micro batteries, the partition plate is pushed away from between the two micro batteries, and the connecting hole is moved to between the two micro batteries. At this time, the two supporting springs push the two movable plates and the micro batteries to move relative to each other, so that the positive and negative poles of the two micro batteries are in contact, the connection circuit is connected, and the indicator light is on, indicating that the head shell and the seat shell are not mis-inserted, and the pin is aligned with the slot position below, thereby achieving the positioning effect, prompting the staff to continue to push the head shell to complete the connection between the head shell and the seat shell, so that the pin is inserted into the slot.

[0004] Although the prior art 1 prevents the situation where plugs of different types but similar appearances are mistakenly inserted into the socket by setting an identification guide pin; however, the slot set in the prior art can only be connected with a rigid pin, and cannot be connected with a flexible wire without a cold-pressed head.
