Centralized junction box for sensor cables

The utility model discloses a centralized junction box for sensor cables, and relates to the technical field of signal acquisition equipment. Comprising a centralized junction box body, the inner side of the centralized junction box body is fixedly connected with a quick connector, the quick connector comprises a fixed head, the fixed head is fixedly connected with a movable head, and the other end of the movable head is electrically connected with a sensor cable. The quick plug has a self-adaptive characteristic, can adapt to various sensor electrical interfaces, and can be used for the access of most industrial standard sensors only through little change. The connection mode is simple and reliable, the sensor measuring points are convenient to disassemble and assemble, the on-site wiring time is saved, and errors are not prone to occurring. The one-point grounding principle of a weak current signal is considered in the design of the joint, the contact resistance is effectively reduced, the signal attenuatio
