Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a cable safety grounding device. Background Art

[0002] A cable is a device that transmits electrical energy or signals from one place to another. It is usually composed of several or several groups of wires, and these wires are insulated from each other. Cables are widely used in modern society, involving many fields such as power, communication, data, transportation, industry, construction, home and entertainment.

[0003] A cable safety grounding device is a device that makes a good electrical connection between the metal casing, frame, etc. of a cable or other electrical equipment and the ground to prevent insulation damage to the electrical equipment or harm to the human body when accidentally electrified, while ensuring the stable operation of the electrical system.

[0004] Existing cable waterproofing usually involves putting heat shrink tubing on the terminal block. The heat shrink tubing covers the entire terminal block and part of the cable to enhance the sealing effect. A hot air gun or special heating tool is used to heat the heat shrink tubing so that it shrinks tightly around the cable to form a sealing layer. However, there is a lack of sealing between the cable and the grounding box. External factors such as moisture, humidity, and dust often invade the grounding box, affecting the normal operation of the cable and grounding system. Utility Model Content

[0005] The utility model discloses a cable safety grounding device, which aims to solve the technical problem that the existing cable grounding lacks sealing treatment between the cable line and the grounding box, and external factors such as moisture, humidity, dust, etc. often invade the inside of the grounding box, affecting the normal operation of the cable and the grounding system.

[0009] In this solution, in order to prevent external factors such as moisture, dust, etc. from invading the inside of the grounding box, a sealing plug is sleeved on the outer wall of the cable, and the inner wall of the sealing plug is tightly attached to the outer wall of the cable, and is used in conjunction with the sealing seat at one end of the wire hole. The sealing plug fits in with the inner wall of the sealing seat, thereby enhancing the sealing between the cable and the grounding box, isolating the interior of the grounding box from the outside space, and preventing external moisture, moisture, and dust from entering the grounding box, affecting the normal operation of the cable and grounding system, and ensuring the safe operation of the cable system.

[0010] In a preferred solution, a fixing plate is provided on the outer wall of the sealing plug, a fixing hole is provided on one side outer wall of the fixing plate, an adjusting screw is provided in the fixing hole, a slot is provided on one side outer wall of the sealing seat, a screw hole is provided on the bottom inner wall of the slot, and the adjusting screw is adapted to the screw hole.

[0011] By adopting the above solution, after the sealing plug is inserted into the jack, the adjusting screw is fixed in the screw hole so that the sealing plug is tightly attached to the inner wall of the jack to prevent the sealing plug from falling off, thereby further improving the sealing performance of the sealing plug and thus improving the sealing effect of the grounding box.

[0012] As can be seen from the above, the cable safety grounding device includes a grounding box and a cable, wherein a threading hole is opened on one side of the outer wall of the grounding box, and further includes:

[0013] The sealing mechanism includes a sealing seat disposed on the inner wall of one side of the grounding box, the sealing seat being located near one end of the threading hole. The inner wall of the sealing seat has an insertion hole, a sealing plug is inserted into the insertion hole, and an extension plug is provided at one end of the sealing plug.
