[0002] In the manufacturing industry, the power supply of equipment often relies on the connection between the power cable and the industrial plug. Currently, this connection is usually made by stripping the insulation of the wire core at the end of the cable and using a screwdriver to fix the wire core to the terminal of the industrial plug. However, this connection method has significant safety hazards. When the cable is dragged by external force, the wire core can easily detach from the terminal, causing a short circuit fault, thereby damaging the equipment and threatening the safety of personnel.

[0003] However, when the existing insulation protection device is used, the cable is directly inspected and repaired, and the pre-fixation effect of the cable inspection part is not high. The insulation protection of the cable inspection part is not high, so that when the cable is dragged by external force, the wire core is easily detached from the terminal, causing a short circuit fault, thereby damaging the equipment and threatening the safety of personnel.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-short circuit insulation protection device is proposed. Utility Model Content

[0007] Furthermore, two groups of the limiting rods are provided, and the positions of the two groups of the limiting rods are distributed symmetrically with respect to the central axis of the connecting block.

[0008] Furthermore, the outer wall of the top screw is provided with an outer spiral which is matched with the inner wall of the inner spiral.

[0009] Furthermore, the outer wall profile of the rubber pressing plate is in an arc shape.

[0010] Furthermore, the insulating elastic protective sleeve is made of polymer insulating material.

[0011] Furthermore, the outer wall profile of the rubber base is in an arc shape.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a rubber pressure plate and an insulating elastic protective sleeve. When the line is routinely inspected and maintained, in order to prevent the line from being separated from the terminal post and causing a short circuit fault, the insulating elastic protective sleeve can first cover and protect the exposed part of the wire core at the cable end to prevent the wire cores from directly contacting each other or other conductive parts.
