Description

A kind of brush boundling contact assembly

Technical field

This utility model is related to a kind of brush boundling contact assembly, belongs to technical field of electric connectors.

Background technology

Bundle interface is to meet electrical connection system large-scale application demand, the interface solution of proposition.With knot Structure is accurate, and connection is reliable, it is easy to the characteristics of manufacturing.At present, on market, the lighter annular contact component of contact engaging and separating force has：Coil spring Hole, hat spring hole and twist needle etc..These contact assembly manufacture difficulty are all very big；It is not easy to realize high efficiency, low cost；Limit High-speed transmission connector is to little profile, high density, high reliability development.

The content of the invention

Seriality when this utility model is produced for existing brush contact, concordance take into account deficiency, and for designing Easily fabricated resilient contact is planted, concrete technical scheme is as follows：

A kind of brush boundling contact assembly, including the pin keeper of many contact pin boundlings, the contact pin end chamfer shape End at an acute angle and obtuse angle end, the acute ends male end for forming pin keeper close to each other of many contact pins, many contact pins Obtuse angle end is mutually away from the female end for forming pin keeper.

Used as the improvement of above-mentioned technical proposal, the pin keeper is positioned in cuff.

Used as the improvement of above-mentioned technical proposal, the cuff crimps into hexagon or 4 points of shapes.

As the improvement of above-mentioned technical proposal, protective case cylinder outside the female end, is cased with, the protection sleeve is fixed with cuff Connection.

Compared with prior art, this utility model has advantages below：First, low connect-disconnect force, low contact resistance；Second, Impact resistance, vibration resistance are not likely to produce hit, make electrical contact with high reliability；3rd, it is easy to implement, high efficiency, low cost.

Specific embodiment

As shown in Figure 1, Figure 2, Figure 3 shows, this utility model provides a kind of brush boundling contact assembly, including many contact pins 10 The pin keeper 20 of boundling, and precise positioning is within cuff 20,10 end of the contact pin chamfer to form acute ends 11 and blunt Angle end 12, the male end 21 for forming pin keeper 20 close to each other of acute ends 11 of many contact pins 10, many contact pins 10 Obtuse angle end 12 is mutually away from the female end 22 for forming pin keeper 20.The technical scheme employs many 10 boundlings of elastic contact pin, is formed One new separate unit body, is easy to post-production to process, and realize male end 21 contact with female end 22 to " elasticity and bullet Property " contact mode, so that it is guaranteed that the high reliability of electrical connection, has lighter contact engaging and separating force concurrently, can be widely applied to little profile, height Density, high frequency, the solution of high speed data transfer component, Jie for carrying out specific embodiment below in the technology of the program Continue.

Embodiment one

As shown in figure 4, by hexagon crimping is carried out to cuff 30, the first form 100 of Fig. 5 cross-sectional shapes is formed, The hexagonal structure can facilitate clamping of other fixed structures to cuff 30, so as to realize the fixation to pin keeper 20.

Embodiment two

As shown in fig. 6, by 4 points of crimping are carried out to cuff 30, the second form 200 such as Fig. 7 cross-sectional shapes is formed, The cuff 30 of 4 points of shapes smoothly can be coordinated with other engaging parts, so as to realize the fixation to pin keeper 20.

Embodiment three

Contact assembly in the program can adopt the structure shown in Fig. 9 to be engaged：Now public affairs of contact assembly End 21 and female end 22 are connected with the attachment structure 40 of other solutions respectively, and now the attachment structure 40 of other solutions can To be welded using tin cream, the connected mode common in the art such as ultrasonic fusing, laser welding carry out tight, reliable electricity Property connection, in this utility model using crimp by the way of, i.e., be closely crimped together with attachment structure 40 by pin keeper 20.

The utility structure 300 of such as Fig. 8, be a kind of attachment structure 40 in actual applications, be called " needle eye " or " flake ", used as a kind of solution towards practical application request, the attachment structure 40 is beyond this utility model structure A part for other solutions, the technical characteristic being not belonging in the technical scheme of this utility model protection.

In such scheme, the male end 21 of single contact is presented male end form 301, now male end form 301 be connected knot Structure 40 is crimped on the side in cuff 30 away from male end 21；The female end 22 of the contact coordinated with which is presented female end form 302, and Protective case cylinder 50 is cased with outside female end 22, the protection sleeve 50 is fixedly connected with cuff 30.

As shown in Figure 10, after in the program, metal coating sleeve 50 is able to ensure that male end 21 is plugged together with female end 22, contact pin 10 Gather and restrain, excessively will not tilt, excessive deformation, the reliable docking of adapter is realized in the elasticity grafting mutually of several contact pins 10.

Above embodiment of the present utility model is described in detail, but the content has been only of the present utility model preferable Embodiment, it is impossible to be considered as limiting practical range of the present utility model, all impartial changes made according to this utility model scope Change and improve etc., still all should belong within this utility model covering scope.
