Abstract
The utility model relates to a measuring circuit switching device, which is characterized by comprising a front-arranged patch panel, a rear-arranged patch panel, six excitation connecting columns and four seven-core connector sockets. The front-arranged patch panel and the rear-arranged patch panel form a box body, an A seven-core connector socket and the six excitation connecting columns are arranged on the front-arranged patch panel, and a B seven-core connector socket, a C seven-core connector socket and a D seven-core connector socket are arranged on the rear-arranged patch panel. By leading an input signal of a three-path sensor into one connector socket integrally, only an output signal cable of the sensor and the connector sockets are directly in butt joint in actual operation, and no measuring circuit is required to be defined uniformly. Therefore, the problems that a measuring channel of a testing system is not utilized fully, the connection mode is complicated, error rate is high and the like are solved and use ratio of the measuring channel and work efficiency of the testing system are improved.
