Description

Gear drive push-pull connector, connector socket and connector plug thereof Technical Field The invention belongs to the technical field of connectors, and particularly relates to a gear drive push-pull connector. Background In the related art, as the number of contacts (or terminals) thereof increases, the insertion force required for coupling the connectors increases, so that the coupling operation of the connectors becomes difficult. Accordingly, low insertion force connectors have been developed. The prior art discloses a header assembly and a socket (application number: CN 201711350486.1) thereof, when the connector is plugged, terminal contacts are hidden in the socket shield until the plug is plugged in place, and then a wrench rotates a rotating shaft to enable a rotating shaft driving terminal to transversely deviate to expose the socket insulation shield. As the shaft rotates, the terminal contacts are laterally displaced more and more until electrical contact is made with the terminals on the plug. Meanwhile, the rotating shaft is also provided with a part with a hook groove characteristic. After the rotating shaft rotates, the hook groove can hook the pin on the plug to realize locking. In the second prior art, a zero-plugging force connector (application number: CN 202311065159.7) with rack transmission is disclosed, the technical scheme is that the rack is driven to rotate through pushing of a key, and after the rotating shaft rotates, a hook groove can hook a pin on a plug to realize locking. The disadvantage of the prior art is that the connector needs to be split into two actions when it is used. Firstly, the plug is inserted in place, secondly, some mechanisms are driven to force the rotating shaft to rotate, so that electric contact and locking are realized. The operation can bring the following problems that firstly, the plugging and separating efficiency is low, the operation usually needs two hands, the requirement on a user is high, secondly, if the rotating shaft is not locked after plugging, the product can not be used, thirdly, if the rotating shaft is not unlocked, the product can not be separated, and the plug and/or the socket can be damaged by forced separation. Fourth, the drive mechanism makes the connector bulky, occupies the user equipment space. Fifth, in the prior art, the electrical contacts are contacted after the header is plugged, so that the contacts have no or a small friction distance, which leads to the product being sensitive to pollution (for example, the electrical contact part is stained, which can lead to poor contact), and thus the contact performance may be reduced. Disclosure of Invention The invention aims to solve the problems in the prior art, and provides the gear drive push-pull connector, which can realize the separation of the electrical on-off and the locking of a product by simply plugging the device when the device is used, and simultaneously reduce the volume of the product. The invention aims to provide a gear drive push-pull connector, which comprises a connector plug and a connector socket, wherein the connector socket comprises a socket shell and a socket signal piece arranged in the socket shell, a cam shaft is further arranged in the socket shell and used for pushing the contact position of the socket signal piece to shift through rotation so as to realize signal contact with a plug signal piece of an adapter connector plug; One side end face of the rack is a driving face; When the head seat is plugged, the connector plug can be abutted with the driving surface so as to push the rack to move along the plugging direction of the connector plug, thereby pushing the cam shaft to synchronously rotate, enabling the plug signal piece to be electrically contacted with the socket signal piece, and simultaneously enabling the pin hook to synchronously rotate along with the cam shaft so as to be hooked at the pin; When the headstock is separated, the pin can push the pin hook to rotate so as to push the cam shaft to synchronously and reversely rotate, so that the plug signal piece and the socket signal piece are separated, and the pin hook are synchronously separated. Preferably, the driving surface is disposed opposite to the insertion direction of the connector plug. Preferably, the plug end of the plug housing forms an abutment portion that cooperates with the driving surface, and the abutment portion is configured to push the rack to move by abutting and cooperating with the driving surface. As a preferred scheme, the plug end of the plug shell is also provided with a shielding sheet, and the shielding sheet can push the rack to move through abutting fit with the driving surface. Preferably, the pin is capable of pushing the rack to move by abutting engagement with the driving surface. Preferably, the driving surface is formed with pin grooves corresponding to the pin positions. Preferably, the rack is mounted in the socket housing and is in slid
