Description

Technical Field

[0001] The utility model relates to the technical field of four-channel signal isolators, in particular to a quick-connect four-channel signal isolator. Background Art

[0002] The signal isolator converts the input signal into output. Its input, output and working power supply are isolated from each other. It is an important component in industrial control systems. At present, when wiring the signal isolator, the insulation layer at the end of the cable needs to be stripped off and then wiring can be performed. The wiring is troublesome, so a quick-connect four-channel signal isolator is needed.

[0003] According to the description of a signal isolator disclosed in the patent website (authorization announcement number: CN 220474914 U), "The utility model discloses a signal isolator, including an isolator body, a plurality of wiring ports are opened on the isolator body, a sliding blade that can slide up and down is installed inside the wiring port, and a clamp seat for cooperating with the sliding blade to cut the outer insulation layer of the cable is also installed inside the wiring port, and the clamp seat and the sliding blade cooperate with each other to clamp the conductor inside the cable to achieve electrical connection, and the clamp seat is driven by a screw installed on the isolator body. When wiring, the utility model can connect the cables without stripping the insulation layer of the cable, thereby making the wiring work convenient and quick, and also avoiding the problem of stripping length being too long or too short."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, when the screw is turned, the clamp seat slides more stably inside the wiring port, and through the arrangement of the clamp seat, the sliding blade and the fixed blade, the insulating layer of the wire can be well separated, so that the wire inside the wire can fully contact with the sliding blade and the fixed blade, so that stable electrical transmission can be performed. However, in actual use, the clamp seat is controlled to move by the screw, and when installing the wire, it is necessary to use external tools, which is cumbersome and difficult to control the moving distance of the clamp seat, which can easily cause the sliding blade and the fixed blade to cut the wire excessively, causing damage to the wire inside the wire. Secondly, the wiring port leaks and dust easily falls into the wiring port, resulting in abnormal contact between the wire and the sliding blade and the fixed blade, which makes the device abnormal in use. Therefore, it is necessary to improve a quick-connect four-channel signal isolator to solve the above problems. Utility Model Content
