Description

Self-locking electronic connector Technical Field The utility model relates to the technical field of electric connectors, in particular to a self-locking type electronic connector. Background The self-locking electronic connector belongs to the field of electronic component connection technology and is mainly used for realizing reliable and stable electric and mechanical connection between devices. The connector is widely applied to scenes such as industrial equipment, consumer electronics, automobile electronics and the like which need to be frequently plugged or subjected to vibration environments, and the core requirement of the connector is to ensure the stability of signal transmission, the convenience of operation and the long-term use reliability. As the integration level of the device is improved and the use scene is complicated, the conventional connector is gradually exposed to the shortage in terms of positioning accuracy, vibration resistance and maintenance convenience. The existing similar connectors have the following structural defects that an accurate guide mechanism is lacking in the plugging process, the contact resistance is increased after long-term use due to misplacement or contact surface abrasion of terminals caused by manual operation deviation, a locking mechanism is designed by screwing threads or buckling, loosening and falling are easy to occur under a vibration environment, unlocking operation is difficult to complete in a narrow space due to cooperation of two hands or by means of tools, internal spring elements are distributed independently and are large in occupied installation space, elastic attenuation is generated due to long-term compression, locking force is reduced, the integral replacement is required due to damage of single components due to insufficient modular design, maintenance cost is high, meanwhile, the fatigue life under high-frequency plugging working conditions is not fully considered by a traditional structure, and comprehensive requirements of modern equipment on connector miniaturization, intelligence and high reliability are difficult to meet. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a self-locking electronic connector to solve the technical problems. In order to achieve the above purpose, the utility model provides a self-locking electronic connector, comprising: the connecting part and the limiting seat are arranged on the back surface of the connecting part, the surface of the connecting part is additionally provided with a wire and an inserting sheet respectively, and the front surface of the limiting seat is provided with an inserting hole and a guide hole; The guide column is arranged on the back surface of the connecting part, and the surface of the guide column is provided with a limit groove; The locking release module is arranged in the inner cavity of the limiting seat and comprises a pressing module, a limiting block, a fixed rod, a lock tongue and a reset spring. After the connecting part is attached to the limiting seat, the inserting piece is inserted into the jack, the guide post is inserted into the guide hole, the pressing module can be pressed, the fixing rod and the connecting structure of the fixing rod are lowered, the lock tongue is tightly attached to the limiting groove, the connecting part is connected with the limiting seat, on one hand, the connecting part and the limiting seat are connected in a plug-in mode and are self-locking, a complex fixing step is not needed, quick installation can be achieved, installation time and cost are greatly saved, on the other hand, the connecting part can be locked on the limiting seat after installation through the self-locking mechanism, looseness caused by vibration or external force is effectively prevented, stability and safety of connection are improved, and meanwhile the connecting part can be easily detached due to the design of the unlocking button, and subsequent maintenance and replacement are facilitated. The method is suitable for various electronic equipment which need quick installation and reliable connection, and has wide application prospect. Preferably, the shape and the position relation between the inserting sheet of the connecting part and the inserting hole of the limiting seat are corresponding. When the connecting part is connected with the limiting seat, the inserting piece is inserted into the jack. Preferably, the guide post corresponds to the guide hole in shape and position, and the front surface of the limit seat is provided with a connecting hole. When connecting portion and spacing seat are connected, the guide post then inserts the inside of establishing into the guiding hole, and spacing seat accessible connecting hole carries out the connection operation simultaneously, and guide post and guiding hole are used for guiding connecting portion to carry out accurate installation on spacing seat.
