CN2145448Y - Plug. socket with spring pressing structure - Google Patents

Abstract

The utility model provides a plug and socket with spring pressing structure, which is characterized in that a contact piece of the plug or the socket adopts a spring pressing structure. The contact performance of the contact piece doesn't depend on the contact piece elasticity, but depend on the effect which uses spring and pressing block to act on the contact piece to guarantee the contact performance. The insertion and pulling of the plug save labor, and the contact piece can not generate deformation and damage; the good electrical conductivity between the plug and the socket is guaranteed.

Description

Plug. socket with spring pressing structure

The utility model relates to a kind of plug, socket.Especially about a kind of plug, socket that adopts the spring laminated structure.

Existing plug, socket, the quality of its contact is that the elasticity of being abutted against contact self guarantees when inserting, and in order to guarantee conductivity, contact chip is the elasticity that adopts Cu alloy material, usually can not guarantee that contact chip has excellent contact, pressure hour between contact chip, easily come in contact bad, when pressure is big, not only make and insert and extract effort, and can make contact chip generation plastic deformation, cause circuit obstructed, or because of producing the fault of electric arc burn, damage contact chip.

The purpose of this utility model provides and a kind ofly inserts and extract easily, plug, socket that electrically contacting property is good, that do not damage contact chip.

Technical solution of the present utility model is: a kind of socket of spring laminated structure, by socket 1, be positioned at the loam cake 2 on the socket 1, be positioned at two contact chips 3 of socket 1, hold-down screw 4, terminal block 5 and terminal screw 6 are formed, it is characterized in that: a slice in two contact chips 3 is a stator, another sheet is an activity template, and the briquetting 7 and the spring 8 that are pressed on the activity template are equipped with in the relevant position in the activity template outside.

The described pair of contact chip 2 manufactured by electric conducting material.

Described briquetting 7 is an insulating material.

A kind of plug of spring laminated structure, by housing 10, be installed on core frame 11 within the housing 10, be fixed in the moving inserted sheet 13 on the core frame 11 and the loam cake 14 that is fixed on the core frame 11 is formed by voussoir 12, it is characterized in that: briquetting 15 and spring 16 are housed between core frame 11 and loam cake 14, and briquetting 15 is pressed on the relevant position of moving inserted sheet 13.

Described briquetting 15 is an insulating material.

The utility model compared with prior art has: adopt the spring laminated structure to replace being abutted against the flexible structure of contact self in the prior art, thereby make the isostasy between the contact chip, not only make plug, socket convenient and strength-saving when inserting and extracting, and plastic deformation do not take place in contact chip, and guaranteeing has good electric conductivity.

Accompanying drawing 1 is the schematic diagram of the utility model embodiment socket.

Accompanying drawing 2 is B-B cutaway views of accompanying drawing 1.

Accompanying drawing 3 is A-A cutaway views of accompanying drawing 1.

Accompanying drawing 4 is schematic diagrames of the utility model embodiment plug.

Below in conjunction with description of drawings embodiment: socket 1 is manufactured by plastics, two contact chips 3 are fixed in the socket 1 by hold-down screw 4, when the plate 9 of plug inserts, activity template in two contact chips 3 separates with stator, activity template is pushed down plate 9 by spring 8 and briquetting 7, and briquetting 7 and spring 8 are set in the socket 1 and by loam cake 2 and fix (Fig. 1).Terminal block 5 is connected with two contact chips 3 by hold-down screw 4, and the other end connects (Fig. 2) by terminal screw 6 with lead.

In accompanying drawing 4, moving inserted sheet 13 is pushed down by briquetting 15 and spring 16, the position of loam cake 14 and core frame 11 restriction briquettings 15 and spring 16, and moving inserted sheet 13 is fixed on the core frame 11 by voussoir 12, and core frame 11 is positioned within the housing 10.
