Description

Three-plug self-locking connector Technical Field The utility model relates to the technical field of plugs, in particular to a three-plug self-locking connector. Background The plug and socket are electric equipment commonly used in real life, the plug and socket used at present are three holes, a power line is needed to be used on all household appliances and used for being connected with a power supply, the structure of the power line comprises wires, plugs and connectors which are connected together, the plugs and the connectors are respectively fixedly arranged at two ends of the wires, the plugs are connected with the power socket in an inserting mode, contact pins are arranged on the electric appliance, and the connectors are directly sleeved on the contact pins, so that the electric appliance is connected with the power supply. In the actual use, because the existing connectors and the pins are directly connected, the connectors tend to slide off the sockets easily due to unexpected stress, and the service life of the electronic device is greatly influenced. Based on the above, the utility model designs a three-plug self-locking connector to solve the above problems. Disclosure of Invention The three-pin self-locking connector comprises a shell and jacks arranged in the shell, pins are arranged on an electric appliance, a sliding groove and a connecting groove are formed in the shell, the connecting groove is vertically arranged, the connecting groove is communicated with the sliding groove and is also communicated with the jacks, a sliding plate is arranged in the sliding groove in a sliding mode, a clamping plate is placed in the connecting groove, connecting rods are fixedly connected to the clamping plate, a yielding groove is formed in the sliding plate, the connecting rods are located in the yielding groove, two corresponding connecting rods are also arranged, a clamping interface is formed in the clamping plate, a fixed block is fixedly arranged in the sliding groove, a stop block and a connecting block are fixedly arranged on the sliding plate, the connecting rods are located between the stop block and the connecting block, an abutting spring is placed in the sliding groove, one end of the abutting spring abuts against the fixed block, a yielding opening is formed in the shell, a pushing plate is fixedly arranged on the sliding plate, the yielding plate is fixedly connected with the yielding opening, the clamping plate is correspondingly arranged in the yielding opening, the clamping plate is also provided with two corresponding connecting rods, the clamping plate is in a state of being far away from the clamping interface when the clamping pin is in a state of being in which the clamping interface is in a state of being far away from the clamping interface, and the clamping pin is in a state of being contacted with the clamping interface. Through adopting above-mentioned technical scheme, after the contact pin inserts, the joint board is in the incline condition, and the joint chucking contact pin of this moment blocks the contact pin, reaches the effect that reduces the contact pin and break away from the socket. Preferably, the stop block is fixedly provided with a mounting block, and one end of the abutting spring is sleeved on the mounting block. Through adopting above-mentioned technical scheme, contradict the spring and install on the installation piece, reduce the running of contradicting the spring, stabilize the contradicting spring. Preferably, a guide groove is formed in the bottom of the sliding groove, and a guide block is fixedly arranged on the stop block and slides in the guide groove. Through adopting above-mentioned technical scheme, when the board that slides removes, the guide block is located the guide way and slides, reduces the rocking of board that slides, stabilizes the board that slides and removes. Preferably, a shifting block is fixedly arranged on the push plate. By adopting the technical scheme, when the push plate needs to be pushed, the fluctuation shifting block is convenient to move the push plate. In summary, the application has the following beneficial technical effects that after the contact pin is inserted, the clamping plate is in an inclined state, and the clamping interface clamps the contact pin at the moment to block the contact pin, so that the effect of reducing the contact pin from being separated from the socket is achieved.
