Abstract

The utility model relates to a novel DIN type radio frequency connector inner conductor, the inner conductor is made by brass material, is equipped with elasticity in its springiness contaction position periphery and cramps the rand. The utility model discloses inner conductor springiness contaction position elasticity is good, reduces the product direct cost and guarantees that the product electric property is reliable and stable to the life of extension product.

Description

A kind of novel DINd type radio frequency connector inner wire

Technical field

The utility model relates to radio frequency connector field, specifically discloses a kind of novel DINd type radio frequency connector inner wire.

Background technology

Radio frequency connector is electronic devices and components important in present mobile communication network, uses all in a large number in the various occasion of various environment of mobile communication; Especially for Module manufacturers, radio frequency connector is important component part in whole passive device cost, particularly DINd type connector, is the one that specification in conventional radio frequency connector is maximum, reaches about more than 10% to whole passive device cost accounting; Therefore the direct material cost of each producer radio frequency connector controls and the useful life of product proposes more harsh requirement.

Existing conventional structure uses Beryllium-Bronze Heat Treatment or phosphor bronze etc. to have flexible materials processing inner wire (as Fig. 1), and after splitting groove closing in, make it that plastic deformation occur, when plugging together with male contact pin, this distortion provides elastic force, to ensure electrical contact.This kind of structure must use beryllium-bronze or phosphor bronze etc. to be worth higher material, if the lower brass etc. of use value does not have the material of favorable elasticity, will less plug together number of times after follow the string and cause poor electric contact; And using phosphor-copper elastomeric material elasticity after long-time plug also can decline, product electrical specifications can progressively decline, and can not ensure index stability.

Utility model content

Goal of the invention of the present utility model is: provide a kind of Elastic Contact position good springiness for overcoming the above problems, cost be low, electric property is reliable and stable, useful life extend novel DINd type radio frequency connector inner wire.

The technical scheme that the utility model adopts is such:

A kind of novel DINd type radio frequency connector inner wire, periphery, described inner wire Elastic Contact position is provided with elasticity banding collar.

Further, periphery, described inner wire Elastic Contact position offers the collar groove for collar described in clamping.

Further, the thickness of described collar is not more than the degree of depth of described collar groove.

Further, described inner wire is made up of brass material.

In sum, owing to adopting technique scheme, the beneficial effects of the utility model are:

The material that inner wire uses by the present invention changes to the lower brass of value by being worth higher beryllium-bronze and phosphor bronze etc., ensure that it has good elasticity by elasticity banding Spring Clip distinctive in structure, thus realize reducing product direct cost and ensureing that product electric property is reliable and stable, and extend the useful life of product.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in figures 2-3, a kind of novel DINd type radio frequency connector inner wire, described inner wire 1 is made up of brass, is provided with the collar groove for clamping elasticity banding collar 2 in its periphery, Elastic Contact position; The thickness of described collar 2 is not more than the degree of depth of described collar groove 3, ensures normal grafting.

Employing of the present invention itself does not have the low brass material of the value of favorable elasticity as rapidoprint to reach the object reducing product cost.Simultaneously for avoiding because of the poor electric contact caused by the bad characteristic of the elasticity of brass material own, and adopting elasticity banding collar 2 inner wire to be split slot part banding to produce elastic force, the continual and steady elastic deformation opposite force of this collar 2 can improve the life-span of product electrical specifications stability and product simultaneously.

Inner wire 1 itself adopts brass processing, processes collar groove splitting slot part, machines to close up to splitting slot part afterwards; Elasticity banding collar 2 is loaded in the collar groove that inner wire 1 processes in advance; Inner wire 1, when plugging together with male contact pin, is split outside groove mouth and is expanded, and the collar 2 be simultaneously mated also is ensued strain and opened, and the collar 2 opened inwardly provides a tightening force, ensures that inner wire splits the Elastic Contact of slot part.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
