Branch test connection device for high-speed data acquisition equipment

Abstract

The invention discloses a branch test connection device for high-speed data acquisition equipment. The connection device comprises an equipment main body, data lines and connectors. The connectors arearranged on the left portions of the data lines and connected with an interface in the right portion of the equipment main body; fixing frames are fixed to the front portion and the rear portion of the right end of the equipment main body through screws; U-shaped frames are arranged on the inner sides of the fixing frames; the left portions of the U-shaped frames are clamped in the fixing framesthrough installation blocks; and the U-shaped frames make contact with the right end of the equipment main body. According to the invention, through cooperation of the fixing frames, mounting blocks and fastening bolts, the U-shaped frames can be conveniently and quickly disassembled and assembled; through cooperation of the U-shaped frames, the mounting plate, a positioning plate, fixing blocks and a long bolt, a connector is conveniently positioned, poor contact is prevented from influencing the test; through first magnets, second magnets and an end cover, dust prevention is conveniently performed on the interface in the equipment main body; dust falling is prevented from influencing use; use is convenient; and connection stability is good.

Description

technical field [0001] The invention relates to the technical field of data acquisition equipment, in particular to a high-speed data acquisition equipment branch test connection device. Background technique [0002] High-speed data acquisition systems are widely used in military, aerospace, aviation, railway, machinery and many other industries. Different from medium-speed and low-speed data acquisition systems, high-speed data acquisition systems contain high-speed circuits, and the clock frequency of more than 1 / 3 of the digital logic circuits in the circuit system is >=50MHz; for parallel sampling systems, the sampling frequency reaches 50MHz, and more than 8 bits in parallel; for The serial sampling system has a sampling frequency of 200MHz. The sampling frequency of the widely used high-speed data acquisition system is generally 200KS / s~100MS / s, and the resolution is 16bit~24bit. [0003] When personnel are testing the equipment, they need to connect multiple sets ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a branch test connection device for high-speed data acquisition equipment, to solve the above-mentioned background technology when testing the equipment, it is necessary to connect multiple sets of data lines to the equipment interface, because there are many data lines, and then When people plug in, it may lead to unstable connection of data lines and poor contact, which will affect the test results
