Description

Technical Field

[0001] The utility model belongs to the field of civil airborne avionics equipment testing, and in particular relates to a liftable cable bracket for induction signal sensitivity testing. Background Art

[0002] The existing induction signal sensitivity test cable bracket only serves as a cable support and only considers the cable laying of the tested cable part. It does not take into account the requirement for the induced magnetic field of the interconnected cables, which requires the excitation cable to be wrapped into a rectangle with a distance of 1m between the two ends of the long side. In addition, since the tested cable area is generally up to 3m long, the tested cable part of the cable bracket is also at least 3m long, which increases the difficulty of storage. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the utility model aims to provide a liftable cable rack for induction signal sensitivity test, proposes the use of a foldable design, divides the original long cable rack into sections, and adds an excitation cable rack so that it can be arranged in a rectangular shape on the bracket, thereby reducing the difficulty of test implementation and improving the accuracy of test implementation to solve the above-mentioned problems.

[0004] In order to solve the above problems existing in the prior art, the technical solution adopted by the utility model is:

[0005] A liftable cable support for induction signal sensitivity testing, comprising a test component and an adjustment component;

[0006] The test assembly includes a test edge and two "L"-shaped side rails, the test edge is formed by splicing a plurality of test boards, and the two "L"-shaped side rails are respectively connected to the two ends of the test edge;

[0007] The adjustment assembly comprises a fixed end of a leg and a movable end of the leg, the fixed end of the leg is connected to the test assembly, and the movable end of the leg is connected to the fixed end of the leg through an adjustment screw.

[0008] The original long test strip is designed as a splicing structure, which is made up of multiple test boards to facilitate carrying.

[0009] By setting the adjustment component and utilizing the fixed end and the movable end of the leg to adjust the height, the height of the test table can be adapted to ensure that the test component is level.

[0010] Furthermore, two adjacent test plates are connected via a raised threaded shaft.

[0011] The raised threaded shaft ensures that the cable is raised by more than 5cm, and the height can be adjusted by yourself using the raised threaded shaft.

[0012] Furthermore, the "L"-shaped siderail includes a long side and a short side, the long side is connected to the test side by a raised threaded shaft, and the long side and the short side are connected by pins on the fixed ends of the legs. The "L"-shaped siderail is designed as a long side and a short side structure, which can be disassembled and assembled for easy carrying. The unfolded long side and short side are supported on the ground by the legs. Since the heights of the test tables are different, the legs are designed to be liftable and adjustable to ensure that the bracket surface is flush. The long side and short side mentioned here are just names and do not represent their relative lengths. An equipment installation port is provided between the two short sides for placement.

[0013] Furthermore, four adjustment components are provided, and all four adjustment components are connected to the short sides. The fixed end of the leg is provided with a long strip-shaped adjustment hole, and the adjustment screw is connected to the adjustment hole. By setting the adjustment hole, the movable end of the leg can be easily adjusted.

[0014] Furthermore, the test board is provided with a plurality of groups of threading holes, and each group of threading holes is provided with two.

[0015] Furthermore, multiple groups of the threading holes are arranged at equal intervals, and circular holes (threading holes) are designed on the primary side and the secondary side. The holes are arranged at equal intervals of three pairs per meter. When conducting electric field or spike tests on interconnected cables, the excitation cable can be passed through one hole in the same row and out of the other, and can be naturally wrapped around the test cable evenly with three turns per meter, thereby ensuring the accuracy of the test.

[0016] Furthermore, the test plate is provided with a plurality of grooves, and the long side and the short side are both provided with a plurality of grooves.

[0017] Beneficial effects of the utility model:

[0018] 1. The utility model solves the problem that the induction signal sensitivity cable is not placed in a standard way, and the excitation cable is difficult to form a rectangular frame to ensure that the distance between the two ends of the long side is 1m. And through the mortise and tenon joints and threads, the long board is divided into multiple parts, making the cable bracket easy to store, and the storage box design is given at the same time. The threaded shaft is raised to ensure that the cable is raised by more than 5cm, and the height can be adjusted by the thread, which meets the standard requirements.

[0019] 2. When the utility model is in use, the main side and the main and secondary sides are placed on the test bench after assembly, and the unfolded L long side and L short side are supported on the ground by the legs. Because the heights of the test tables are different, the legs are designed to be adjustable to ensure that the bracket surface is flush.

[0020] 3. Circular holes are designed on the primary and secondary sides. The holes are arranged at equal distances of three pairs per meter. When conducting electric field or spike tests on interconnected cables, the excitation cable can be passed through one hole in the same row and out of the other. It can be naturally wound around the tested cable evenly with three turns per meter, ensuring the accuracy of the test.

[0021] 4. Each support plate is designed with a notch, where you can use a rolling belt or tape to bundle the cables to prevent the cables from moving. It is recommended to use Velcro for bundling, which can be reused. BRIEF DESCRIPTION OF THE DRAWINGS
