Rectangular electric connector for equipment cabinet, with axial automatic compensation function

Abstract

The invention relates to a rectangular electric connector for an equipment cabinet, with an axial automatic compensation function, comprising a plug and a socket; the plug comprises adapter pins, a lower plug base, an upper plug base, a lower plug shell, a riveted pipe, an upper plug shell, springs, a pin, a lower base, an upper base, a shell and jacks; the socket comprises screws, an internal teeth lock washer, a fixing plate, a lower socket base, an upper socket base, a socket shell and contact pins; a plurality of springs are evenly distributed around the lower base, and the total spring force of the springs is as much as 3-5 times the total sum of the separating force of a single pin of a contact element; the distance between a flange plate of the plug and a flange plate of the socket can be controlled to be 0-6mm; and the effective contact length between each adapter pin and each jack is as much as at least 1mm longer than the distance between the flange plate of the plug and the flange plate of the socket. The distance between the flange plate of the plug and the flange plate of the socket can be controlled within a larger range, and the axial size of the socket arranged on the device is small, therefore, the invention has higher practical value.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors. Background technique [0002] Rectangular electrical connectors for cabinets generally refer to rectangular electrical connectors similar to those specified in GJB177A, which are mainly installed on panels or cabinets. Usually the socket is fixedly installed on the equipment, and the plug is fixedly installed on the panel of the cabinet drawer, and the insertion and separation of the plug and the socket are realized by pushing and pulling the drawer. [0003] In order to ensure the effective mating of the plug and the socket, the distance between the plug flange and the socket flange after the rectangular electrical connector for the cabinet is mated is generally required to be 0-1mm, and the maximum is no more than 1.5mm. However, in the actual application process, due to the limitation of the cabinet structure and other reasons, it often occurs that the distance between the plug ...

Problems solved by technology

[0005] The method of increasing the contact length of the contact piece increases the axial length of the plug and socket at the same time, which requires a larger axial space size of the equipment

However, the internal space of general equipment is limited, especially the axial dimension of the space for installing the socket is limited, and the effective length of the contacts in the socket cannot be extended, which limits the scope of use of the product.
