Short circuit electric connector

Abstract

The invention discloses an electric connector with a short circuit function, which comprises a plug and a socket, wherein the socket comprises a socket shell (9), a socket base (10), and two jacks (7); the plug comprises a plug shell (1), a plug base (3) and two pins (2); the socket also comprises an elastomer and a short circuit module; the short circuit module can move in a direction vertical to insertion of the plug and the socket under the elastic force effects of the elastomer to electrically contact the two jacks (7) simultaneously, and thus, the short circuit connection between the two jacks (7) is realized; and during the insertion process between the plug and the socket, the plug shell (1) of the plug pushes the short circuit module to enable the two jacks (7) to be insulated with the short circuit module respectively. The electric connector of the invention can be used for electrical connection between two pieces of equipment with floating existing in the axial position, the structure is compact, the appearance size is small, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to an electrical connector with a short-circuit function between contacts. Background technique [0002] As electronic equipment becomes more and more sophisticated, some electronic equipment requires that the connector socket installed on it has a short circuit function between the contacts of the socket before the plug is mated to prevent static electricity or other electromagnetic interference from causing damage to the electronic equipment; and After the plug and the socket are butted and mated, insulation between the contacts of the socket is required to transmit signals normally. At present, most of the connectors with short-circuit function adopt the method of short-circuit board or short-circuit ball. [0003] The short-circuit board method is mainly to design a metal short-circuit board on the butt end of the socket, and the metal short-circuit board has an insertion ho...

Problems solved by technology

[0005] The above-mentioned commonly used connectors with short-circuit structure all push the short-circuit module axially through the insertion of the plug or socket to realize the short-circuit or insulation between the socket contacts, which has strict requirements on the axial relative position between the plug and the socket. Cannot be used reliably in the presence of axial position fluctuations between two devices

E.g, figure 1 In the short-circuit structure of the short-circuit board shown in the "dart" structure, 21 refers to the "dart" part where the contact can elastically shrink radially inward, and the part referred to by 60 is a metal short-circuit board, which is in place when the plug and the socket are not fully connected. , the shortest insulation distance between the contact and the short-circuit board is m, which is less than the insulation distance n specified in the design, resulting in a decrease in the insulation performance of the product, and even an unexpected short-circuit phenomenon
