Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a cable connector protection device for mines. Background Art

[0002] Mining cables refer to wire and cable products used in the coal mining industry for ground and underground equipment, including cables for coal mining machines, conveyors, communications, lighting and signaling equipment, as well as electric drill cables, cap lamp wires and power cables for underground mobile substations. When connecting mining cables through connectors, it is generally necessary to provide protection for the cable connectors.

[0003] Mining cables are usually wrapped with tape after being connected. This method may cause the tape to detach when the connection is exposed to high temperature conditions, which poses a safety hazard. In addition, after the cables are connected, the connectors of the two cables are easily pulled, which can easily cause secondary breakage and affect safety. Therefore, we propose a mine cable connector protection device to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a mine cable connector protection device.

[0005] In order to solve the above technical problems, the utility model provides a cable connector protection device for mines, including an insulating sheath and a second arc-shaped clamping plate. A heat dissipation hole is opened in the middle of the insulating sheath, and a copper sleeve is fixedly sleeved on the middle of the insulating sheath. Fins are fixed on the surface of the insulating sheath, and the fins pass through the copper sleeve. The two end sides of the insulating sheath are respectively fixed with a first arc-shaped clamping plate through a connecting rod, and the two ends of the first arc-shaped clamping plate are fixed with a first boss, and the two ends of the second arc-shaped clamping plate are fixed with a second boss. The first boss and the second boss are fixedly connected by screws, and the two ends of the insulating sheath are threaded with a locking sleeve, and the inner walls of the two ends of the insulating sheath are fixed with an annular retaining ring, and the inner walls of the two ends of the insulating sheath are sleeved with a sealing ring, and the sealing ring rests on the retaining ring.

[0006] Preferably, an observation port is provided on the surface of the copper sleeve, and a transparent plate is fixed in the observation port via a sealing strip.

[0007] Preferably, the surface of the locking sleeve is provided with anti-slip grooves.

[0008] Preferably, a plurality of heat dissipation holes are provided, and the heat dissipation holes are arranged in a circular array.

[0009] Preferably, anti-slip pads are fixed to the inner walls of the two first arc-shaped clamping plates and the second arc-shaped clamping plates.

[0010] Compared with the related art, the beneficial effects of the present invention are:

[0011] 1. In the present invention, the cable head of one of the two cables to be connected is passed through the insulating sheath, and then the cable heads of the two cables are connected by a professional connection method. Then, the connecting head parts of the two cables are pulled back into the insulating sheath. At this time, the insulating sheath can provide protection for the joint of the cables. There is no need to assemble the insulating sheath, and the integrity of the insulating sheath can be maintained. The two retaining rings and two locking sleeves can limit the two sealing rings to prevent the two sealing rings from loosening and falling off. The sealing ring is used to prevent dust and water from entering the interior and causing damage to the connecting head parts of the two cables;

[0012] 2. In the utility model, the cable head connection of the two cables can dissipate heat through the heat dissipation holes, and the heat is diffused to the outside through the fins and the copper sleeve, thereby ensuring that the connection does not accumulate heat, which has a good protective effect; the cables can be fixed by the first arc-shaped clamping plate and the second arc-shaped clamping plate, thereby avoiding pulling at the cable connection and affecting the connection stability, which has a good protective effect.
