Embodiment Construction

[0028] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] In order to solve the problems of the prior art, the present invention provides a shielded dark room threading device, such as Figure 1 to Figure 5 As shown, the body of the shielded darkroom threading device is a rectangular box body 1 made of metal, and the specific size can be customized according to the requirements for cable penetration through the wall. One end of the box body 1 has a mounting structure with the darkroom shield body. The box body 1. There are multi-layer movable partitions 4 or 5 with semicircular card slots and fixed partition slots 6 inside; the movable partitions 4 or 5 are divided into upper movable partitions 5 and lower movable partitions 4. The upper movable partition 5 and the low...

Abstract

The invention belongs to the technical field of shielded darkroom threading and particularly relates to a threading device of a shielded darkroom. The technical scheme adopted by the invention is as follows: multiple layers of movable partition plates with semicircular clamping grooves and fixed partition plate insertion slots are arranged in a rectangular box body, each shielding partition plate is divided into an upper block and a lower block, the middle of each shielding partition plate is provided with semicircular clamping grooves, and the partition plates are designed to be capable of being overlapped; electromagnetic leakage preventing filler is injected in the box body; a top cover of the box body is provided with a buckle edge structure, and a complete shielding body is formed by the top cover and the box body. According to the threading device of the shielded darkroom, the movable partition plates for clamping cables can be replaced according to the thickness of cables of test equipment, so that the convenience of cable mounting is guaranteed, and the shielding performance of the shielded darkroom is guaranteed; multiple layers of partition plates with the semicircular clamping grooves can be mounted in the box body according to signal characteristics, so that outside interference is prevented from being introduced into the darkroom from the cables; the device has the advantages that the test efficiency is increased effectively, the accuracy of a test is improved effectively, and the completeness of an equipment test status is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of threading in a shielded darkroom, in particular to a threading device in a shielded darkroom, in particular to a threading device capable of conveniently replacing different types of EUT test cables. Background technique [0002] At present, there are mainly two types of known threading methods in shielded darkrooms. One is to use a fixed wall-through interface board, which is realized by installing a fixed joint and an attached seat on the board, and connecting the test cable to both ends of the attached seat to realize threading. Function. Relatively fixed standard cable interface mode, this method is easy to implement, such as: N type, BNC type, NC type, universal light, etc. However, for the connecting cables of the EUT (equipment under test), due to the variety of cables and complex types of connectors, it is unrealistic to install the accessory seat on the interface board in advance. Temporary inst...
