Abstract

The utility model relates to a broad-frequency coaxial arrester of copper aluminium structure for protecting the coaxial device in broadcast television system, microwave communication, mobile communication base station. The coaxial arrester of copper aluminium structure comprises an inner conductor, an outer conductor, an insulator, a short-circuit device shell and a short-circuit device short bar, wherein the outer conductor main body in the middle of the outer conductor is aluminum alloy material and a connection segment with aperture of larger than the middle aperture of the outer conductor is set on at least one end of the outer conductor main body and a back segment of an embedment piece of copper material is mounted on the connection segment of the outer conductor main body in way of interference fit and the front segment of the embedment piece is used as the outer conductor of a joint part. The broad-frequency coaxial arrester can ensure good conductivity performance, contact elasticity and contact strength when splicing with the other coaxial device and at the same time the consumption of copper material is greatly reduced and the material cost is reduced.

Description

Broadband coaxial lightning arrester with copper-aluminum structure

Technical field

The utility model relates to the broadband coaxial lightning arrester with copper-aluminum structure of system and equipment protection in a kind of radio data system, microwave communication, the mobile communication base station.

Background technology

The lightning arrester that is used for radio data system, microwave communication, mobile communication base station system and equipment protection generally includes the insulator between inner wire, outer conductor and the outer conductor; also comprise be positioned at inner and outer conductor middle part and with the axial perpendicular short-circuiting means housing and the short-circuiting means short-circuit rods of inner and outer conductor, the two ends of internal and external conductor are provided with and are used for the joint that is connected with other coaxial components.In traditional lightning arrester structure, for guaranteeing blank area and have electric conductivity and contact resilient and intensity preferably being connected of other devices that outer conductor adopts whole copper material usually, makes the material cost of entire device higher.

Summary of the invention

Technical problem to be solved in the utility model is, provides a kind of material cost lower, can guarantee the reliable broadband coaxial lightning arrester with copper-aluminum structure of joint electrical contact performance simultaneously.

Broadband coaxial lightning arrester with copper-aluminum structure of the present utility model includes outer conductor, inner wire, insulator, short-circuiting means housing and short-circuiting means short-circuit rods, and the outer conductor main body in described outer conductor stage casing is an aluminum alloy materials; At least one end of outer conductor main body is provided with the linkage section of aperture greater than the outer conductor middle aperture, have the back segment of the insert of one section copper material to be installed among the above-mentioned linkage section of outer conductor main body in the mode of interference fit, the leading portion of insert is as the outer conductor of blank area.

The inner surface of the back segment of described insert contacts with the outer surface of one section insulator, that is, the back segment of insert is fixed between the linkage section inner surface of insulator outer surface and outer conductor main body, thereby can guarantee that it embeds the fastness that connects.

The utility model has adopted the outer conductor structure of copper aluminium combination, its blank area is a copper material, can guarantee that it and other coaxial components have excellent conducting performance, contact resilient and contact strength when pegging graft, its outer conductor main part is an aluminium alloy simultaneously, can significantly reduce the use amount of copper material, reduce material cost; In addition,, improved cooperation intensity, also can reduce the use of copper material simultaneously to greatest extent, further reduced cost because insert embeds the outer conductor main body from the inboard, and utilizes insulator that its inboard is gripped.
