Description

A kind of mover for electric connector

Technical field

It the utility model is related to a kind of element of electric connector, and in particular to a kind of mover for electric connector.

Background technology

The public transport bearing capacity in China is huge, and each column railway, subway are sequentially connected by some compartments, between each compartment Signal transmit by the way that power transmission cable and control signal wire are attached into transmission by connector.

With the development of technology, bullet train, the speed per hour more and more higher of subway and other modes of transport, function is more and more complete, So, the circuit that needs to connect between compartment is also more and more, becomes increasingly complex, and existing electric connector typically passes through male pin mother pin Socket connection, one group of electric connector is provided with some male pin mother pins, public because electric connector often plugs during compartment use Pin mother's pin small volume, it is complicated, it is extremely easy to wear, cause male pin or female pin service life short, later maintenance cost is high, And contact exception easily causes signal transmission fault, influences the normal operation of electric connector.

Utility model content

In view of this, the application provide a kind of mover for electric connector, have it is wear-resistant, service life grow it is excellent Point.

To solve above technical problem, technical scheme provided by the utility model is a kind of mover for electric connector, Including fixing end, the fixed end cap is equipped with elastic device, and the elastic device is set with contact jaw, and the fixing end is used to cover A circle first boss is provided with shock mount, the contact jaw is used to be provided with second boss at pocketed springs, the elastic device Both ends are respectively engaged with the first boss and the second boss.

Preferably, the fixing end includes shank, and the contact jaw includes hollow metal cylinder, in the metal cylinder Be nested with hat spring, the hat spring be sleeved on shank and all the time with the fixed end in contact.

Preferably, the contact jaw also includes terminal made of antifriction alloy, and one end of the metal cylinder is provided with described Second boss, the other end of the metal cylinder are installed with the terminal.

Preferably, the terminal is specially the terminal that end face is Kufil layer gold.

Preferably, the terminal is specially the terminal that end face is AgCul0 or AgCu20 alloy-layers.

Preferably, sleeve is set with outside the elastic device, the both ends of the sleeve connect the contact jaw and institute respectively State fixing end.

Preferably, the sleeve is connected in the fixing end by latch.

Preferably, the elastic device is specially a kind of metal spring.

Compared with prior art, its detailed description is as follows by the application：

The fixing end of the mover is used to install on electrical connectors, and is connected with wire, and the fixing end has a circle First stop ledge, the contact jaw are provided with second stop ledge of circle, and the spring is fastened in the first stop ledge and second In stop ledge, because contact jaw needs constantly to move back and forth in swapping process, therefore pacify spring-loaded two side faces easily Wear, prolonged abrasion may result in spring loose or dislocation, therefore the first stop ledge of the application and second is stopped Dynamic boss not only can be with the radial displacement of limited spring, and can reduce spring and the contact surface of other parts, reduces friction Caused structural wear, improve the service life of mover.

Kufil has good electric conductivity, mobility and wellability, preferable mechanical performance, hardness height, wearability It is preferable with resistance fusion welding, therefore terminal contacts as the contact jaw of mover, it is necessary to coordinate with stator, Kufil can be effectively The wearability of mover is improved, and then improves the service life of mover.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and have The utility model is described in further detail for body embodiment.

As shown in figure 1, a kind of mover for electric connector, including fixing end 1, the fixing end 1 include a circle The shank 11 of cylindricality, the shank 11 are set with elastic device 3 outside, and the other end of the elastic device 3 is sleeved on contact jaw 2 On, the fixing end 1 is provided with first stop ledge 12 of circle, and the contact jaw 2 is provided with second stop ledge 23 of circle, The both ends of the elastic device 3 are set in the stop ledge 23 of the first stop ledge 11 and second and clamping.

The contact jaw 2 includes terminal 21 and hollow metal cylinder 22, and one end of the metal cylinder 22 is provided with second Stop ledge, for being set with the elastic device 3, the terminal 21 is fixedly mounted on the other end of the metal cylinder 22.

The inwall of the metal cylinder 22 is nested with hat spring 5, and the hat spring 5 is sleeved on shank 11, the shank 11 In the interior pars intramuralis of metal cylinder 22, and keep contacting with hat spring 5 all the time.

The terminal 21 be specially end face be Kufil layer gold terminal, preferably specially end face be AgCul0 or The terminal of AgCu20 alloy-layers, terminal more preferably made of AgCul0 or AgCu20 alloys, the end face of the terminal 21 are Arc surface.

Sleeve 4 is set with outside the elastic device 3, one end of the sleeve 4 is sleeved on the periphery of metal cylinder 22, and passes through Shoulder hole progress is spacing, and the other end of sleeve 4 connects the fixing end 1, the fixing end 1 and the sleeve 4 and consolidated by latch 6 Fixed connection, the sleeve are used to limit moving radially for contact jaw, the contact jaw is axially moveable all the time.

The elastic device 3 is specially a kind of metal spring.

The fixing end of the mover is used to install on electrical connectors, and is connected with wire, and the fixing end has a circle First stop ledge, the contact jaw are provided with second stop ledge of circle, and the spring is fastened in the first stop ledge and second In stop ledge, because contact jaw needs constantly to move back and forth in swapping process, therefore pacify spring-loaded two side faces easily Wear, prolonged abrasion may result in spring loose or dislocation, therefore the first stop ledge of the application and second is stopped Dynamic boss not only can be with the radial displacement of limited spring, and can reduce spring and the contact surface of other parts, reduces friction Caused structural wear, improve the service life of mover.

Kufil has good electric conductivity, mobility and wellability, preferable mechanical performance, hardness height, wearability It is preferable with resistance fusion welding, therefore terminal contacts as the contact jaw of mover, it is necessary to coordinate with stator, Kufil can be effectively The wearability of mover is improved, and then improves the service life of mover.

It is flexible in radial direction to be preced with spring, therefore is preced with spring and is sleeved on the shank, hat spring follows contact jaw back and forth to transport Keep contacting with shank all the time in dynamic process, therefore the structure of the application is respectively provided with good electric conductivity when moving back and forth.

The terminal is used to be contacted with the end face of stator, and electric current passes through terminal, metal cylinder, hat spring, shank successively, It is transferred on the wire of fixing end connection, completes the transmission of signal.

A kind of mover for electric connector that the application provides, its anti-wear performance is good, simple in construction, and can be from structure Friction in upper reduction reciprocatory movement, the stable running of structure is improved, improve the service life of mover.

It the above is only preferred embodiment of the present utility model, it is noted that above-mentioned preferred embodiment should not regard For that should be defined to limitation of the present utility model, the scope of protection of the utility model by claim limited range.For For those skilled in the art, do not departing from spirit and scope of the present utility model, can also make some Improvements and modifications, these improvements and modifications also should be regarded as the scope of protection of the utility model.
