Abstract
The invention provides a bent type jack contact for a crown spring. The bent type jack contact consists of a bent type jack and a crown spring type contact ring. The tail end of the bent type jack is in a 90-degree bent structure; no inner space for mounting the crown spring type contact ring exists in equipment at a butt-joint end; and the crown spring type contact ring is fixed in the bent type jack through interference fit of an inner hole. The bent type jack contact provided by the invention has the advantages of simple structure, high machining efficiency, high machining precision of the 90-degree bent part, good consistency, reliable signal transmission, simple assembly and good structure stability, and can be used for effectively ensuring the direction of a bending pin. The bent type jack contact is applicable to a bend-plug type circuit connector for a printed board, and has the advantages of smaller contact distance, light plug force requirement and large contact row quantity.
Description
Technical field
The present invention relates to the jack contact structure of electric connector, belong to technical field of electric connectors.
Background technology
Along with electric connector is installed and used the increasingly sophisticated of environment; The electric connector contact performance has also been proposed higher more requirement; Not only require the signal transmission reliable; Should possess also simultaneously that contact engaging and separating force is low, contact resistance is stable, anti-vibration, characteristic such as shock-resistant, hat spring socket contact belongs to the contact of better performances, and the hat spring formula jack contact in the electric connector is basically all formed (as shown in Figure 1) by pillar, contact ring (hat spring hole), straight formula jack or pin at present; Version is single, and disadvantage is arranged:
1, in the traditional hat spring formula jack contact pillar and pin fixing through circumferential interval riveted joint or border in abutting connection with realization; When pin needs bending because pillar wall thickness thin (being generally 0.2mm); Riveting point intensity can not be born the radially effects of stress such as tail end bending fully; Even loosening or obscission take place in pillar and pin after bending, reduce the reliability of signal transmission;
2, jack contact can only be pressed into the pedestal from the connector butt end, and can not anti-rotation after being pressed into, can't satisfy the polarity contact (as the weldering cup that welds cup type contact towards) installation and instructions for use; If address the above problem through cutting flat structure in the processing of pillar end; Then reduce the efficient of part processing on the one hand, also increase the size of part on the other hand, contact row number (is arranged as 6) more for a long time in connector; The bender installs the meter difficulty, and bending is of low quality;
3, the pedestal of contact being installed need be provided with the stepped hole that matches with the pin step, and requirement is with the pillar mating holes, have the axiality requirement with the pin mating holes, causes the base mold of connector to be opened making difficulty higher.
Summary of the invention
The objective of the invention is to,, a kind of bendable hat spring socket contact is provided to the problems referred to above that prior art exists, be used for little spacing (as less than 1.905mm * 1.905mm), arrange the curved formula electric connector of number more.
Institute's bendable hat spring socket contact; It is characterized in that: this jack contact is made up of curved formula jack and hat spring formula contact ring; Said curved formula jack tail end is a 90o bending structure; Butt end equipment is not installed the endoporus of hat spring formula contact ring, and hat spring formula contact ring is fixed in the curved formula jack through the interference fit with this endoporus.
Said curved formula jack butt end oral area is provided with and turns over the riveting step.
The corresponding pedestal of outer wall installation site, curved formula jack butt end is provided with two circle support thorns.
Be provided with step between said curved formula jack butt end and the tail end.
The radially side opening that the lower end of said curved formula jack butt end endoporus is provided with counterbore and connects with this counterbore.
The present invention is preced with the spring socket contact and has following characteristics:
(1) simple in structure, working (machining) efficiency is high, and 90 ° of dogleg section machining accuracies are high, high conformity;
(2) the part kind is few, and assembling only needs oral area to turn over riveting can to realize, and hat spring formula contact ring is bigger with curved formula jack direct contact surface, and contact resistance is more stable, thus guaranteed effectively the signal transmission reliably;
(3) assembling is simple, and the structure stationarity is good, can effectively guarantee the direction of clubfoot.
Four, description of drawings
Fig. 1 is existing hat spring socket contact piece structure sketch map.
Fig. 2 is a bendable hat spring socket contact piece structure sketch map of the present invention.
Fig. 3 is the structure cutaway view of curved formula jack in the bendable hat spring socket contact of the present invention.
Among the figure: 1-curved formula jack, 1a-support thorn, 1b-step, 1c-turn over riveting step, 1d-endoporus, 1e-counterbore, 1f-side opening, 2-hat spring formula contact ring.
Embodiment
Below in conjunction with accompanying drawing hat spring socket contact concrete structure according to the invention is done further to detail.
As shown in the figure; Bendable hat spring socket contact according to the invention; Form by curved formula jack 1 and hat spring formula contact ring 2; Said curved formula jack 1 tail end is a 90o bending structure, and the endoporus ld of hat spring formula contact ring 2 is not installed in the butt end, and hat spring formula contact ring 2 is fixed in the curved formula jack through the interference fit with this endoporus ld.Said curved formula jack 1 butt end oral area is provided with and turns over riveting step 1c; Outer ring surface corresponding pedestal position of mounting hole in butt end is provided with the two circle support thorn 1a that keep at a certain distance away; Be provided with step 1b between butt end and the tail end; The radially side opening 1f that the lower end of butt end endoporus 1d is provided with counterbore 1e and connects with this counterbore, the material of said curved formula jack 1 is a copper alloy.
The major function of above-mentioned curved each structure division of formula jack is:
(1) support thorn 1a is used to realize the fixing of jack contact and connector base that support is thrust the mutually corresponding hole wall of pedestal and can be produced certain radial load, prevents the change of jack contact clubfoot direction;
(2) jack step 1b is used to locate its punching stroke, and as the acting surface of punching press anchor clamps, reduces the damage of punching press pressure to contact coating;
(3) the jack oral area turns over riveting step 1c and guarantee to be preced with the key that spring formula contact ring is not deviate from from jack; After hat spring formula is touched circle and is packed into; Inwardly turn over the finish dimensional that riveting turns over after the riveting and guarantee, can limit the insertion of over dimensioning contact pin to a certain extent through turning over the riveting anchor clamps;
(4) being the interference fit relation between curved formula Socket bore 1d and the hat spring formula contact ring 2, to guarantee producing suitable normal pressure between hat spring contact ring and curved formula Socket bore, is to guarantee to contact the key to reliable contact;
(5) bottom outlet 1e and side opening 1f are fabrication hole in the jack, are used to guarantee the abundant circulation of plating bath, improve the uniformity and the consistency of coating.
Bendable hat spring socket contact of the present invention is applicable to that the contact spacing is less, contact engaging and separating force light, the more bend cutting formula printed circuit board connector of contact row's number.
