CN202749554U - Self-clamping socket - Google Patents

Abstract

The utility model discloses a self-clamping socket which comprises a casing and a connecting member. The connecting member is located in the casing and electrically connected with a lead, the connecting member is formed by an insulation groove, a fixed sheet, a movable sheet and a compressed spring, and the fixed sheet, the movable sheet and the compressed spring are arranged in the insulation groove. The fixed sheet is reliably connected with the insulation groove, one end of the compressed spring is reliably connected with the insulation groove, the other end of the compressed spring is reliably connected with the movable sheet, and a gap between the fixed sheet and the movable sheet is not less than 0.5CM. The self-clamping socket effectively enables a contact surface of the socket and a plug to be tight, increases contact area, reduces resistance of the contact surface, and can effectively avoid power interruption, large heating amount or fire striking and the like caused by bad contact.

Description

A kind of from clamping socket

Technical field

The utility model relates to a kind of from clamping socket, belongs to the low-voltage electrical appliance apparatus field.

Background technology

The scope of application of all kinds of sockets in productive life is extremely wide, but its plug-in unit is single conductive metal thin plate in present employed all kinds of sockets, be in the external plug connection procedure, only rely on plug-in unit self elastic deformation ability to guarantee clamping degree with plug, therefore, its contact reliability is relatively poor, after long-time the use, loosening or the phenomenon such as open circuit of the connection that causes because of reasons such as plug-in unit flexibility decrease very easily appears, thereby cause in use loose contact occurring even cause the heating or spark phenomenon, serious threat Electrical Safety.

Summary of the invention

The utility model purpose just is to overcome above-mentioned deficiency, provides a kind of from clamping socket.

For achieving the above object, the utility model is to be achieved through the following technical solutions:

A kind of from clamping socket, comprise housing and plug connector, wherein plug connector is positioned at enclosure interior and is electrically connected in wire, described plug connector is made of insulation tank, stator, activity template and stage clip, described stator, activity template and stage clip all place insulation tank inner, and stator reliably is connected with insulation tank, and stage clip one end reliably is connected with insulation tank, the other end reliably is connected with activity template, and stator and activity template gap are not less than 0.5CM.

Stator, activity template material are copper or copper alloy.

Stage clip is spring or shell fragment.

The utility model effectively makes the socket and plug contact-making surface more tight, increases contact area, reduces the resistance of contact-making surface, and can effectively avoid the phenomenons such as or sparking large because of power failure, caloric value that loose contact causes.
