Description

A kind of fastening type shield terminal

Technical field

This utility model relates to a kind of terminal, particularly to a kind of fastening type shield terminal.

Background technology

At present, the publication number on market is radome and the Set Top Box that the Chinese patent of CN203788415U discloses a kind of tellite, and it includes radome body, and the sidewall of described radome body is provided with through hole; It is arranged on the feedthrough capacitor of described radome outer body wall. Wherein, the centre bore of described feedthrough capacitor connects with described through hole, and described feedthrough capacitor pole plate is conductively connected with described radome body; It is located in the F head in the centre bore of described feedthrough capacitor, is conductively connected with another pole plate of described feedthrough capacitor.

In such scheme, radome body welds with a pole plate of described feedthrough capacitor, and welding process there will be overlap, liquid metal stream in weld seam overflows to the unfused mother metal of underheat or from the root of weld, what formed after cooling is not overlap with the metal tumor of mother metal fusion, overlap is often accompanied by incomplete fusion, dreg defect, is easily caused crackle. Meanwhile, overlap changes the actual size of weld seam, and stress can be brought to concentrate.

Utility model content

The purpose of this utility model is to provide a kind of fastening type shield terminal without welding.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of fastening type shield terminal, including radome, described radome is provided with feedthrough capacitor, described feedthrough capacitor is connected to F head, described feedthrough capacitor inserts radome and turns down to radome inwall, forms the riveted structure of square brackets shape at radome inwall.

Pass through technique scheme, the riveted structure protruded by feedthrough capacitor during assembling is inserted in the groove that radome is corresponding and compresses riveted joint to radome inwall, ultimately form the riveted structure of square brackets shape, each position corner cambered of riveted structure is bigger, when feedthrough capacitor produces axial rotatory force, stress produced by riveted structure is shared counteracting by each position by this rotatory force, avoid the rotation of feedthrough capacitor and loosen, improve the tautness of connection, and instead of welding step, the fixing overlap that will not produce when welding of this structure, ensure that the surface finishing of stationary plane, avoid the welding residual stress of junction.

This utility model is further arranged to: described riveted structure includes two pieces of Contraband shape blocks, and described Contraband shape block includes bearing the horizontal rib of vertical direction active force, bearing the vertical rib of horizontal direction active force.

Pass through technique scheme, when feedthrough capacitor produces the active force of vertical direction, the horizontal rib of Contraband shape block plays the neutralization effect to this active force, the active force of vertical direction is perpendicular to horizontal rib, it is achieved bigger pressure application surface amasss, and the pressure therefore produced is less, ensure that Stability Analysis of Structures not easily deformation, the principle communicated, vertical rib shares the active force of horizontal direction, is also improve attachment structure stability.

This utility model is further arranged to: the cross section of described feedthrough capacitor is circle, and the outer rim of described riveted structure is inscribed within the projection of this circle.

Pass through technique scheme, ensure that the riveted joint area of riveted structure maximizes on the one hand, the scope avoiding riveted structure on the other hand is excessive beyond circular drop shadow spread, just active force to radome is produced at feedthrough capacitor, riveted structure beyond drop shadow spread's part can be produced shearing force by this active force, therefore the scope of riveted structure is decreased, it is ensured that the maximum riveted joint area in zone of reasonableness.

This utility model is further arranged to: the described radome inwall some salient points of outwardly formation.

By technique scheme, salient point adds the clamping level that radome coordinates with exterior components, it is ensured that tautness during cooperation.

This utility model is further arranged to: described F head is provided with screw thread.

Pass through technique scheme, it is achieved that F head removably connects with joint outer part, has reached higher cooperation compactness, screw out during dismounting after screwing.

In sum, this utility model has the advantages that and be instead of Welding Structure by the riveted structure of square brackets shape, achieve the fixing of radome and feedthrough capacitor, stress produced by riveted structure is shared counteracting by each position by the rotatory force of feedthrough capacitor, avoid the rotation of feedthrough capacitor and loosen, avoid overlap and the generation of surface soldered residual stress simultaneously, improve service life.
