Background technique

Many instruments or electrical equipment need to short-circuit some open-circuit terminals during transportation or storage to avoid electromagnetic interference, and need to be non-self-recoverable open-circuit treatment before use.

Utility model content

The task of the utility model is to provide an electrical connector plug for short circuit and open circuit conversion, which can automatically release the short circuit before entering the working condition, so that the electric equipment connected to it can work normally.

In order to achieve the above tasks, the utility model adopts an electrical connector plug for short-circuit and open-circuit conversion. An insulator is arranged in the plug housing of the plug, and a through hole is arranged in the insulator, and a guide rod is slid and inserted in the through hole. A pair of parallel pins are fixed, and the insulator at the corresponding position of the pins is provided with a jack for plugging and unplugging the above pins, and a pawl mechanism is provided on the rod surface of the guide rod. After the corresponding pin socket is pulled out, the ratchet of the mechanism prevents the sliding back of the guide rod and the back insertion of the pin socket.

The pins on the guide rod are axially positioned on the guide rod through an insulating guide mounting block, and the pair of pins communicate with each other through the conductor embedded in the insulating guide mounting block, and the insulating guide mounting block stops The screw fit slide fits in a corresponding slide cavity within the insulator of the plug.

The guide rod is screw-mounted in a nut pre-embedded and fixed in the insulating guide mounting block, the pawl is elastically installed in the axial grooves on both sides of the guide rod, and the root of the pawl is close to the insulating guide mounting block The inner surface of the guide rod on the nut side is provided with flat and/or cross grooves.

At the other end of the through hole relative to the pin insertion hole, a T-shaped step hole section is set, and a stopper is provided at the end of the same side of the guide rod, and a stopper is installed on the guide rod in the step hole in the stopper. return spring.

The plug insulator is composed of a plug upper insulator and a plug lower insulator, a circuit board is sandwiched between the two insulators, and the root of the jack is connected to the circuit board.

Since the plug housing of the utility model is provided with an insulator, and a through hole is provided in the insulator, a guide rod is slid and inserted through the through hole, and a pair of pins parallel to each other are fixed on the guide rod. The insulator is provided with a socket that cooperates with the above-mentioned pin insertion, and a pawl mechanism is provided on the rod surface of the guide rod. After the pawl of the pawl mechanism is pulled out of the corresponding pin socket, it prevents the guide rod from moving. Sliding back and back insertion of the pin socket, therefore, when the guide rod is pushed out by other equipment that cooperates with it, the pin and socket are automatically separated and pulled out, and the plug realizes automatic conversion from short circuit to open circuit. The structure design is simple and reasonable , the conversion is reliable. In addition, the guide rod is screw-mounted in a nut pre-embedded and fixed in the insulating guide mounting block. Rotating the guide rod can make the pawl withdraw from the surface of the guide rod, and reverse the guide rod to reinsert the plug pins, so that the The utility model has the advantage of being recyclable. Moreover, a return spring is worn on the guide rod in the step hole in the stop head, so that the guide rod can automatically return to its position after the ratchet is retracted, and the pin insertion hole is automatically inserted again.
