Description

Self-short-circuit pushing electric connector

Technical field

The invention relates to the technical field of electrical connectors, in particular to a self-shorting push-on electrical connector, which is suitable for occasions where self-short-circuiting can be quickly mated and separated.

Background technique

In some special connection occasions, the connector is required to have a self-short circuit function to shield external interference, prevent electrostatic hazards, and enhance system security. Under normal circumstances, a short-circuit cover or contact is added, and the short-circuit cover or contact is manually inserted into the connector to realize a short-circuit during the mismatching. In this case, there are reasons such as artificial forgetting or poor connection, which makes the short-circuit unreliable.

Summary of the Invention

In order to solve the above technical problems, the present invention provides a simple and compact structure, which does not need external short-circuit components, self-short circuit without plugging in, and uses a self-short circuit with high safety performance to push against the electrical connector.

The technical solution adopted by the present invention is: a self-short-circuit push-to-back electrical connector, including a plug and a socket, characterized in that the plug includes a head housing, a plug push plate, a plug short-circuit ring, a plug reed, and a plug spring, The inner wall of the head housing is evenly distributed with a plurality of plug springs arranged in the axial direction. The tail of the plug spring passes through the tail housing and is connected externally. The inner wall of the head housing is connected with a plug push plate, and the plug push plate and the head housing. A plug spring is tightly arranged between the tails of the body, and a plug shorting ring is provided on the plug push plate around the outer circumference of the plug in contact with or disengaged with a plurality of plug springs uniformly distributed around the circumference; the socket includes a locking sleeve, Seat housing, socket push-out plate, socket push-in plate, socket short-circuit ring, socket spring, socket spring, the inner wall of the seat shell is connected to the socket push-in plate, and the socket push-in plate is circumferentially connected to a plurality of circumferentially arranged axially. The socket reed, the housing shell locking sleeve, the tail of the socket push-out plate is inserted into the circumferential gap between the head of the seat shell and the head of the locking sleeve, and the socket is provided between the tail of the socket push-out plate and the seat shell. Spring, the inner wall of the head of the socket push-out plate is set around it Peripheral wall with a plurality of circumferentially equispaced outlet socket as a shorting ring contact spring or disconnected state; the socket corresponding to the socket the pushing plate inserted connector plugs of the push plate.

It also includes a guide pin, the guide pin is axially penetrated in the head housing, and a guide sleeve corresponding to the guide pin is provided on the push plate in the socket.

A sealing ring is fitted on the end surface of the head of the socket push-out plate to fit the end surface of the head housing.

The contact body plug reed and socket reed of the present invention are punched parts, and the reeds are uniformly distributed around the circumference of the non-metal head housing and the push plate of the socket to maintain electrical insulation between each other.

The plug push plate, the socket extra push plate, and the socket inner push plate of the present invention are moving parts. The plug push plate and the socket extra push plate are respectively fixed with a short-circuit ring. The short-circuit ring is a ring-shaped metal conductor. When the plug and the socket are not plugged in, The plug push plate is located at the head of the head housing under the force of the plug spring. The electrical conduction path between the short circuit ring of the plug on the plug push plate and a plurality of plug springs in the circumferential direction realizes a self-short circuit when the plug is not plugged in. In the same way, the electrical conduction path between the socket short-circuit ring on the socket extrapolation board and a plurality of socket springs in the circumferential direction realizes a self-short circuit in the unplugged state of the socket.

The load pressure design of the plug spring can effectively maintain the reliability of the plug's self-short circuit. After pushing against the socket, the plug spring is compressed, the plug push plate is out of position, and the plug short-circuit ring is disengaged from the elastic contact surface of the plug spring to release the self-shorting. Short circuit; Similarly, the load pressure design of the socket spring can effectively maintain the reliability of the socket's self-short circuit. After the socket is pushed and mated, the socket spring is compressed and the plug push-out plate is out of position, which drives the insert short circuit ring out of the socket spring. Elastic contact surface to eliminate self-short circuit.

When plugs and sockets are mated, through the guidance of the guide pins and guide sleeves, the connector can find its own center in a certain range to avoid mismating or plugging.

During mating, the outer surface of the head of the plug head housing is pushed against the end surface of the socket push-out plate, the socket push-out plate is forced to compress the rear socket spring, the socket push-out plate is retracted, and the socket push-plate is on the plug. The push plate abuts and pushes the plug push plate to compress the plug spring at the rear. The plug and socket are disconnected from the short circuit. After the mating is completed, the plug spring and the socket spring contact to achieve electrical conduction. After mating, it can be locked by locking. The sleeve pushes the external push plate of the socket, which facilitates rapid separation under the action of two springs during energy storage.

The connector of the invention can simultaneously realize short-circuit protection in a mismatched state, and has high use safety.
