Thirty-two-channel matrix switch board

Abstract

The invention relates to the technical field of matrix switch boards, in particular to a thirty-two-channel matrix switch board. The thirty-two-channel matrix switch board comprises a board card mainbody, wherein a wire concentrator is installed on the right side of the board card main body through screws, butt joint ports are equidistantly arranged on the wire concentrator, transmission lines are equidistantly connected to the right side of the board card main body, wiring terminals are arranged on the output ends of all the transmission lines, all the wiring terminals are matched with the corresponding butt joint ports in an inserted manner, namely, all the wiring terminals can be matched and connected with the corresponding butt joint ports, so that the phenomenon of disordered windingof cables of the board main body can be reduced. Elastic metal cards are equidistantly and integrally formed on the left side and the right side of the wire contractor, the transmission lines and thecontacts in butt joint with the wiring terminals can be fixed by means of two adjacent elastic metal cards and the semi-circular grooves formed on the upper parts, and the phenomenon of falling at the butt joint part in the shaking process can be reduced.

Description

Technical field [0001] The invention relates to the technical field of matrix switch boards, in particular to a 32-channel matrix switch board. Background technique [0002] The 32-channel matrix switch board can be widely used in various switching situations and analog signal switching occasions. It adopts programmable control form and cooperates with the host computer labview software to realize multi-channel data acquisition and processing. Specific applications include program-controlled switches. , Discrete components, signal source switch control. [0003] However, the existing switch board still has defects in use: [0004] 1. The number of channels of the existing relay board is not sufficient for the test and measurement requirements, the wiring is complicated and it is easy to cause the cables to be tangled in disorder during the wiring process; [0005] 2. The expansion of the board is not strong, which is not conducive to flexible on-site calling. The number of channels s...

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.
