Short-circuit protection socket with self-detection structure

Abstract

The invention discloses a short-circuit protection socket with a self-detection structure, and belongs to the technical field of electrical connectors. The short-circuit protection socket comprises asocket housing, wherein three insulators are laminated in the socket housing; a plurality of groups of plughole components are distributed on the first insulator; each plughole component comprises a pair of communication plugholes, an insulating ejection post, a grounding contact and a detection plughole; a contact head matched with the shape of a contact boss is arranged at one end of each grounding contact; a detection pin matched with the detection plughole is arranged at the other end of each grounding contact; and grounding pressure springs are arranged between the contact heads and grounding plates. With the adoption of insertion and stripping operation of a plug and the socket, when the socket is not connected with the plug in an inserted manner, a self-short-circuit link is established, and self-short-circuit protection is performed on equipment; and when the socket is connected with the plug in an inserted manner, the self-short-circuit link is automatically disconnected, andself-detection is performed on a disconnection state of the self-short-circuit link. Therefore, a signal transmission error is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a short-circuit protection socket with a self-detection structure. Background technique [0002] Among the existing connectors, some connectors are used in fire control products or in environments with relatively high current requirements. The static electricity or induced current in the non-use state of electrical components will have an adverse effect on the entire device, so it is necessary to A self-short-circuit protection structure is added to the connector to transmit the static electricity or induced current to the protection circuit. [0003] The Chinese patent with the publication number CN207664362U discloses a multi-core self-short-circuit protection connector structure. Although it can play a good short-circuit protection function and avoid damage to equipment or devices caused by static electricity, it cannot detect whether the short-circuit protection...

[0003] The Chinese patent with the publication number CN207664362U discloses a multi-core self-short-circuit protection connector structure. Although it can play a good short-circuit protection function and avoid damage to equipment or devices caused by static electricity, it cannot detect whether the short-circuit protection structure is completely disconnected. , once the short-circuit structure is incompletely disconnected, signal transmission errors are likely to occur, resulting in abnormal actions or steps of the equipment, causing unnecessary danger or irreparable losses
