Abstract
The invention relates to a split level heat proof socket which consists of a contact part of a jack, a deformed spring, an insulating board, an upper insulator, a lower insulator, a shell and a compression ring. The contact part of the jack is aligned by the upper insulator and the lower insulator and fixed in the shell by the compression ring; the insulating board can rotate in the space between the upper insulator and the shell; the insulating board and the upper insulator are provided with a plurality of corresponding round holes with different sizes; and a plurality of the deformed springs are arranged on the outer circle of the insulating board and the insulators. Due to the elastic force of the spring, the insulating board can be rotated to cover the hole position of the upper insulator and prevent the heat radiation so as to play the role of heat insulation and protection, thus leading the socket to be characterized by compact structure, small space usage and excellent heat proof performance.
Description
One, technical field
The invention belongs to technical field of electric connectors, relate in particular to a kind of Splitlevel heat resistance socket.
Two, background technology
Anti-thermal socket generally is made up of thermal insulation board and insulator, between thermal insulation board and insulator, the helical spring with initial compression amount is installed.Its mode of operation has two kinds, and a kind of is under the spring force effect, rotates dislocation between thermal insulation board and the insulator, and the position, hole is sheltered from each other, plays the effect of thermal insulation protection.Another kind is under the spring force effect, realizes axial separation between thermal insulation board and the insulator, is spaced from each other, because the effect of thermal insulation board stops that thermal radiation acts directly on the insulator, realizes protection across the mature.In above-mentioned two kinds of mode of operations; The helical spring of first kind of mode of operation is installed on the cylindrical of insulator, and the radial space that takies is bigger, and the helical spring of second kind of mode of operation then is installed in the insulator; Taken the useful space of contact, caused that radial and axial space increases.Two kinds of mode of operations all can increase the volume of socket to some extent, and narrow and small application scenario, space is restricted.
Three, summary of the invention
The purpose of this invention is to provide a kind of Splitlevel heat resistance socket, its structure is made up of jack contact, deformed spring, thermal insulation board, upper insulator, lower insulator, shell and trim ring; Jack contact is aimed at through upper insulator, lower insulator and is remained on correct position; Be fixed in the shell through trim ring; Thermal insulation board rotates in can be between upper insulator and the shell set space, and the correspondence position with upper insulator on the thermal insulation board is provided with the circular hole that several differ in size; A plurality of deformed springs evenly are set on the cylindrical of thermal insulation board and upper insulator.In order to make the Kong Weiyu upper insulator dislocation of thermal insulation board; Deformed spring with initial compression amount has been installed on the cylindrical of thermal insulation board and upper insulator, and deformed spring bends to " V " shape by spring steel wire, and two ends are separately fixed on thermal insulation board and the upper insulator; Because upper insulator is fixed; Under the spring force effect of deformed spring, promote thermal insulation board and rotate, realize the dislocation of the position, Kong Weiyu upper insulator hole of thermal insulation board, shelter from the position, hole of upper insulator; Stop thermal radiation, play the effect of thermal insulation protection.Stressed even for what thermal insulation board was rotated, on the cylindrical of thermal insulation board and upper insulator, be uniform-distribution with a plurality of deformed springs, the quantity of deformed spring and spring steel wire diameter can be confirmed according to the spring force of space allowable and actual needs.Thermal insulation board and upper insulator be the state during hole dislocation position under the deformed spring effect.When plug and socket plug together, utilize the effect of plug, at first rotate thermal insulation board, thermal insulation board is alignd with the position, hole of upper insulator, realize normally plugging together and electrical communication of electric connector then, this moment, deformed spring was compressed.State when thermal insulation board turns to and aligns with position, upper insulator hole.Plug, promotes thermal insulation board and returns to the dislocation state under the spring force effect of deformed spring with after socket separates.
In addition, in order to strengthen effect of heat insulation, between upper insulator and thermal insulation board, designed the air gap layer; The effect that can play good reduction heat conduction efficiency and improve electrical insulation properties, simultaneously, after the design air clearance layer; Can reduce the contact area between thermal insulation board and the upper insulator; Improve positioning accuracy, reduce frictional resistance between the two, prevent thermal insulation board generation jam phenomenon.In addition, in order further to improve the surplus of anti-thermal design, when structural design; Jack contact is not exposed to the end face of upper insulator; But sink in the upper insulator, design has increased the creepage distance between the jack contact exponentially like this, and the end face of having avoided upper insulator effectively is after charing; Cause the rapid decline of insulation resistance, improve the surplus of anti-thermal design.
Adopt deformed spring to be rotated dislocation; And design air clearance layer and jack contact is sunk to the beneficial effect that the technical scheme in the upper insulator reaches be; Make the socket of design have compact conformation; It is little to take up room, and the characteristics that thermal protective performance is good are for narrow space provides a kind of good anti-thermal solution.
