An electrical connection system

Abstract

This invention provides an electrical connection system, including a base and a plug. The base contains a connection system and a mounting slot for the connection system. The connection system consists of connecting metal conductors and an auxiliary holding mechanism. The connecting metal conductors include a connecting body, a limiting part, and a limiting hook. The auxiliary holding mechanism includes an isolating body, an isolating body mounting slot, and a spring. The mounting slot for the connection system is located within the base and includes a mounting slot, a limiting protrusion, and a movable chamber. The connection system consists of at least two sets of connecting metal conductors and two sets of auxiliary holding mechanisms, with the connecting metal conductors spaced apart to form slots. The auxiliary holding mechanism provides auxiliary holding for the connecting metal conductors, preventing poor contact. The auxiliary holding mechanism also secures the plug, preventing it from loosening. The isolating body of the auxiliary holding mechanism prevents the connecting metal conductors from contacting the spring, thus preventing heat generated by the connecting metal conductors from being transferred to the spring and reducing its elasticity.

Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment connectors, and in particular relates to an electrical connection system. Background Art

[0002] Connectors for electrical equipment are usually connected in the form of sockets. Sockets use conductive copper sheets as internal connections. The copper sheets not only guide the current but also need to clamp the plug to maintain tightness. After the socket has been used for a long time, the copper sheets will gradually lose their elasticity due to metal fatigue. Over time, the plug will not be clamped. When a gap is created between the copper sheet and the plug, sparks are likely to occur, leading to poor contact and fire accidents. Summary of the invention

[0003] In view of the above-mentioned deficiencies, the present invention provides an electrical connection system, which uses an auxiliary supporting mechanism to assist in supporting the connecting metal conductor to prevent poor contact.

[0004] The technical solution adopted by the present invention to solve the technical problem is: an electrical connection system, including a seat body and a plug body, the seat body is provided with a connection system, a connection system installation groove, and the connection system is composed of a connection metal conductor and an auxiliary holding mechanism;

[0012] The isolating body is provided with an isolating protrusion and isolating body limiting walls located on both sides of the isolating protrusion; a spring installation circular hole is provided at the rear of the isolating body;

[0013] The insulator and the spring are installed in the insulator installation groove. When no connecting metal conductor is installed, the insulator is supported by the spring, and the insulator limiting wall presses against the frame of the insulator installation groove.

[0014] Furthermore, the connector is installed in the connection system installation groove of the seat body, the isolating body and the spring are installed in the isolating body installation groove, the isolating protrusion is tightly against the back of the connecting part, the limiting hook connecting the metal conductor is tightly against the wall where the limiting protrusion and the movable bin intersect, and a gap is provided between the limiting wall of the isolating body and the frame.

[0015] Furthermore, the cross section of the contact surface between the connecting portion of the connector and the plug-in body is a straight line or an arc, and the distance from the straight line to the center point O is less than the length from the corresponding contacting surface high point of the plug-in body 1 to the center O'.

[0016] Furthermore, the insert body is inserted into the seat body, the spring is compressed, a gap is provided between the limit hook connected to the metal conductor and the rear wall of the movable chamber, and a gap is provided between the connector and the wall surface of the installation groove.

[0021] The beneficial effects of the present invention are:

[0022] The present invention supports the connecting metal conductor toward the insert body through the auxiliary supporting mechanism, which is conducive to the close fit between the connecting metal conductor and the insert body, and prevents the connecting metal conductor from losing its elasticity due to metal fatigue, which may cause poor contact.
