(3) summary of the invention:
The purpose of this utility model is to design a kind of double-body bike microstrip filter encapsulation shielding box, it can overcome conventional encapsulation shielding box some shortcomings in the assembling welding and the course of processing, strengthened the filter welding reliability simultaneously, it is more crisp to make it to be specially adapted to quality, can not pass through the encapsulation shielding of the fixing high temperature superconduction wave filter microstrip substrate of well format.
The technical solution of the utility model: a kind of double-body bike microstrip filter encapsulation shielding box, comprise base, loam cake, standard radio frequency joint three part parts, it is characterized in that base and loam cake are concave structure, both fastenings are the box body of a sealing.
Above-mentioned said base is " recessed " type structure just, the screwed hole that is used for fixing loam cake is arranged on it, its inner bottom surface has the screwed hole and the radio-frequency joint connecting hole that are used for fixing for the welding plane of welding filter microstrip substrate, two end plates is used for fixing and connects the standard radio frequency joint on it.
Welding plane on the above-mentioned said base, shape can be rectangle, also can be square.
Above-mentioned said loam cake is for falling " recessed " shape structure, and the size of its physical dimension and base adapts, and the width of recess is identical with the width of base, and the degree of depth of recess is identical with the height of base, and entire length is identical with base length.
Above-mentionedly cover the fixed via that adapts with base on said, be useful on the fixed via of reservation, be used for the filter package shielding box is fixed in cold head.
Above-mentioned said radio-frequency joint is the standard radio frequency joint, and the size of its splicing ear is consistent with the joint connecting hole on the base end plate, the screwed hole position consistency on its fixed via and the base end plate.
Superiority of the present utility model is: 1, this case double-body bike microstrip filter encapsulation shielding box at traditional shielding box in processing, the problem that exists in the assembling process, improved shielding box structure, adopt " recessed " shape version, reduced difficulty of processing and processing cost, improved machining accuracy; 2, the structure of this encapsulation shielding box is fit to welding assembly, effectively the protecting filter microstrip substrate; 3, this encapsulation shielding box has been taken into account the shielding and the problem with grounding of filter, has guaranteed the radio-frequency performance that filter is good.
