Thirty-two channel matrix switch board

Abstract

The invention relates to the technical field of matrix switch boards, in particular to a 32-channel matrix switch board, comprising a board card body, a hub is installed on the right side of the board card body through screws, and the hub is also equidistantly arranged There are docking ports, and the main body of the board is also connected with transmission lines equidistantly to the right side, all the output ends of the transmission lines are installed with terminals, and all the terminals are plugged and matched with the corresponding docking ports , that is, all the connection terminals can be matched and connected with the corresponding docking ports, so that the phenomenon of chaotic winding of the main body cables of the board can be reduced. The left and right sides of the hub are integrally formed with elastic metal cards at equal distances. With the help of two adjacent elastic metal cards and the semi-circular groove on the upper part of the hub, the connection between the transmission line and the connecting terminal can be fixed, reducing the vibration during the shaking process. A situation where the butt joints come off occurs.

Description

technical field [0001] The invention relates to the technical field of a matrix switch board, in particular to a thirty-two-channel matrix switch board. Background technique [0002] Thirty-two-channel matrix switch board can be widely used in various switch and analog signal switching occasions. It adopts programmable control form and cooperates with the upper computer labview software to realize multi-channel data acquisition and processing. Specific applications include program-controlled switches. , Discrete components, signal source switch control. [0003] But, also there is defect in existing switch board when using: [0004] 1. The number of channels of the existing relay board does not meet the test and measurement requirements, the wiring is complicated and it is easy to cause confusion and winding of cables during the wiring process; [0005] 2. The expansion of the board is not strong, which is not conducive to flexible use on site. The number of channels switc...

AI Technical Summary

Problems solved by technology

[0004] 1. The number of channels of the existing relay board does not meet the test and measurement requirements, the wiring is complicated and it is easy to cause confusion and winding of cables during the wiring process;

[0005] 2. The expansion of the board is not strong, which is not conducive to flexible use on site. The number of channels switched by the relay cannot be edited, and there is no way to superimpose it at will.
