Abstract
The invention discloses a general jack contact element consisting of a jacket, a contact ring arranged in the jacket, and a pin connected with the lower end of the jacket. A locating slot is arranged at the upper end of the pin, the contact ring is a cylindrical part formed by rolling and combining two pairs of parallel elastic arms, the size of the upper end of the contact ring is larger than that of the lower end of the contact ring, the upper end of the contact ring is in interference fit with the jacket, locating teeth used for realizing the peripheral location of the contact ring are arranged at the lower end of the contact ring and are clamped in the locating slot. The general jack contact element is simple in structure, reasonable in design and reliable in contact, can better realize the plugging match with a square contact pin and a circular contract pin, and has stronger novelty and practicability.
Description
Technical field
The invention belongs to technical field of electric connectors, be specifically related to a kind of general jack contact.
Background technology
The contact numerous types of connector, commonly used have cylindrical shape contact, stranded elastic contact pin contact, wire spring socket contact, hat spring socket contact and a reed-type jack contact.In these contacts, wire spring socket contact, hat spring socket contact and stranded elastic contact pin contact are the simply supported beam mechanical model, have higher contact reliability; The reed-type jack contact is the cantilever beam mechanical model, and contact reliability is low.In addition, the reed-type jack contact is the punching out formula, only is suitable for plugging together coupling with square contact pin contacting piece.The existence of these factors has influenced the popularization and the use of such contact to a certain extent.
Summary of the invention
Technical problem to be solved by this invention is to above-mentioned deficiency of the prior art; A kind of general jack contact based on the simply supported beam mechanical model is provided; It is simple in structure, reasonable in design and contact is reliable; Can realize preferably plugging together coupling simultaneously, have stronger novelty and practicality with square contact pin and circular contact pin.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of general jack contact; It is characterized in that: by sheath and be arranged on the inner contact ring of sheath and form with pin three parts that the sheath lower ends connects, be provided with location notch on the said pin, said contact ring is intervolved by two pairs of elastic arms that parallel and forms a cylindrical component; Said contact ring upper end size is greater than the lower end size; Between said contact ring upper end and the sheath is interference fit, and said contact ring lower end is provided with and is used to realize the circumferentially positioning tooth of location of contact ring, and said positioning tooth is entrapped in the location notch.
Above-mentioned a kind of general jack contact is characterized in that: the connected mode of said pin and sheath is riveted joint.
The present invention compared with prior art has the following advantages:
1, simple in structure, reasonable in design; This jack contact is by sheath and be arranged on the inner contact ring of sheath and form with the pin that the sheath lower ends connects, and is provided with location notch on the pin, and contact ring is intervolved by two pairs of elastic arms that parallel and forms a cylindrical component; Contact ring upper end size is greater than the lower end size; Between contact ring upper end and the sheath is interference fit, and the contact ring lower end is provided with and is used to realize the circumferentially positioning tooth of location of contact ring, and positioning tooth is entrapped in the location notch.
2, the present invention adopts the elastic arm of two pairs of parallel distributions; One end fixedly other end slip forms the simply supported beam mechanical model; And the cooperation through positioning tooth and location notch, realize circumferentially fixingly, satisfy square contact pin and plug together the directivity requirement when mating; And the local measure of adopting interference fit, realize good assembly process process and low and stable contact resistance.
3, contact is reliable, can realize preferably plugging together coupling simultaneously with square contact pin and circular contact pin, has stronger novelty and practicality.
Through accompanying drawing and embodiment, the present invention is done further detailed description below.

Embodiment
Like Fig. 1, a kind of general jack contact shown in 2 and 3; By sheath 1 and be arranged on the inner contact ring 2 of sheath 1 and form with pin 3 three parts that sheath 1 lower ends connects; Said pin 3 upper ends are provided with location notch 6; Said contact ring 2 is intervolved by two pairs of elastic arms that parallel 4 and forms a cylindrical component, and said contact ring 2 upper end sizes are interference fit greater than the lower end size between said contact ring 2 upper ends and the sheath 1; Said contact ring 2 lower ends are provided with and are used to realize the circumferentially positioning tooth 5 of location of contact ring 2, and said positioning tooth 5 is entrapped in the location notch 6.
Said pin 3 is riveted joint with the connected mode of sheath 1.
Among the present invention, contact ring 2 is core parts of general jack contact, and through blanking, bending, volume circle with behind tooth, form the cylindrical component with two pairs of parallel elastic arms 4, the lower end of elastic arm 4 is a cantilever by the thick beryllium bronze band of 0.1mm for it.In order to obtain higher consistency and elasticity, contact ring 2 has carried out heat treatment behind punch forming, and after gold-plated, forms final part.The positioning tooth 5 of contact ring 2 lower ends, the circumferential location of realizing contact ring 2 makes the fixed-site of two pairs of elastic arm 4 circumference of contact ring 2, satisfies the directivity requirement when plugging together coupling with square contact pin, realizes plugging together coupling with square contact pin and circular contact pin simultaneously.The contact ring 2 that machines is assembled in the sheath 1, contact ring 2 and sheath 1 is assembled on the pin 3 again, and the positioning tooth 5 of contact ring 2 snaps in the location notch 6 of pin 3, and realization contact ring 2 is circumferentially located.After riveted and fixed is carried out in the end of sheath 1, just formed general jack contact.
During use, when contact pin and jack contact plugged together, square contact pin or circular contact pin were in a of contact ring 2 (or a1) zone and 4 contacts of two pairs of parallel elastic arms, and formation is electrically connected.Elastic arm 4 cantilever ends of contact ring 2 can slide along the inwall of sheath 1 when plugging together, and such end is fixed, and the other end has slidably just formed the simply supported beam mechanical model, has guaranteed higher contact reliability.In addition, has lower contact resistance, except that contact ring 2 and contact pin contacting piece are four sections parallel connections on the certain-length contact in order to guarantee general jack contact; Contact ring 2 adopts local interference fit with sheath 1, and contact ring 2 is designed to the little form of the big other end of an end, and the small end guiding can easily be assembled in the sheath 1; Big end is an interference fit with sheath 1 then, leans on special tooling, contact ring 2 is press-fitted put in place; Design has improved assembly process process like this; Be distorted, be out of shape equivalent damage when both having prevented contact ring 2 assembling, and guaranteed again that contact ring 2 and sheath 1 have reliably to be electrically connected, because contact ring 2 and 1 of sheath are one section interference fit on the circumference; Have bigger contact pressure, equally have low and stable contact resistance with wire spring socket.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any restriction, every technical spirit changes any simple modification, change and the equivalent structure that above embodiment did according to the present invention, all still belongs in the protection range of technical scheme of the present invention.
