[0002] Weak current installation refers to the installation of electrical equipment in buildings or industrial sites to meet the needs of information transmission and control. It mainly includes the construction and maintenance of systems such as television, telephone, computer, monitoring, security, access control, etc. Usually, low voltage and small current are used for transmission. Compared with strong current installation, weak current installation belongs to a relatively complex and delicate field, and issues such as signal transmission distance, anti-interference, reliability, and grounding protection need to be considered. At the same time, relevant safety codes and standards also need to be complied with. Weak current installation is widely used in various occasions such as commercial centers, office buildings, schools, hospitals, factories, etc., bringing convenience and comfort to people's lives and work.

[0003] When installing weak current, sometimes two wires need to be connected, and then the connection position is wrapped with insulating tape to prevent the copper wire inside the wire from being directly exposed outside and causing electric leakage. However, when using insulating tape to wrap the wire to prevent electric leakage, when the wire fails and needs to be removed or repaired, it is not convenient for maintenance personnel to find the connection point, the maintenance time will be prolonged, and the wire cannot be repaired in time. Moreover, when repairing, the tape needs to be torn off before the repair or removal work can be carried out, the work is rather troublesome, and the work efficiency is low. Therefore, a protective insulating clip for weak current installation is proposed. Content of the Utility Model

An anti-slip pad is installed on the inner side of the limiting sleeve. The clamping rod is rotatably connected to the insulating shell through a pin shaft.

[0010] Preferably, the lower part of the rack is slidably connected to the fixed plate. The two clamping rods are arranged at a certain angle on the upper and lower sides of the matching block. The transmission rod is rotatably connected to the insulating shell.

[0011] Preferably, the sliding rod is slidably connected to the fixed plate. Matching sleeves are arranged on both sides of the threaded rod. The matching sleeves are fixedly connected to the fixed plate. An inner matching sleeve is also installed on the inner side of the matching sleeve.

Swing rods 6 are rotatably connected to both sides of the pushing plate 5 through pin shafts. A clamping sleeve 7 is detachably connected above the swing rods 6.

[0026] Furthermore, in order to facilitate clamping of the copper wire positions and improve the connection stability of the wire connection positions, the swing rod 6 is rotatably connected to the fixing plate 4 through a pin shaft. An insulating protection pad 8 is arranged on the inner side surface of the clamping sleeve 7. Two sets of sliding rods 10 are fixedly connected above the pushing plate 5. Two sets of connecting plates 11 are fixedly connected to both sides of the sliding rods 10.

[0027] Furthermore, in order to facilitate clamping and limiting of the positions of the wires where the copper wires are not exposed, and prevent the wires from loosening due to external reasons, which may affect the stability of the joints, one end of the connecting plate 11 is fixedly connected to a rack 12. A gear 13 is meshed and connected to one side of the rack 12. A transmission rod 17 is fixedly connected inside the gear 13. A matching block 14 is fixedly connected to the surface of the transmission rod 17.

[0028] Furthermore, two sets of clamping rods 15 are respectively arranged on the upper and lower sides of the matching block 14. A limiting sleeve 16 is detachably connected to one end of the clamping rod 15. An anti-slip pad is arranged on the inner side surface of the limiting sleeve 16. The clamping rod 15 is rotatably connected to the insulating shell 1 through a pin shaft.

[0029] Furthermore, to improve the clamping stability on the wire surface, the lower part of the rack 12 is slidably connected to the fixing plate 4. The two sets of clamping rods 15 are arranged at a certain angle on the upper and lower sides of the matching block 14. The transmission rod 17 is rotatably connected to the insulating shell 1.

[0030] Furthermore, in order to facilitate clamping and limiting of the copper wire positions, the sliding rod 10 is slidably connected to the fixing plate 4. Matching sleeves 18 are arranged on both sides of the threaded rod 3. The matching sleeves 18 are fixedly connected to the fixing plate 4. An inner side surface of the matching sleeve 18 is also provided with a matching sleeve 18.

[0031] Furthermore, in order to improve the insulation and high safety of this insulating clip during use, the clamping sleeve 7, the limiting sleeve 16, and the matching sleeve 18 are all made of insulating materials with relatively high hardness. The insulating protection pad 8 is made of an insulating material with good air permeability. Chute grooves are opened on the left and right sides of the fixing plate 4. The swing rod 6 slides in the chute grooves.

[0032] Further, for the convenience of the staff to observe and for subsequent maintenance or removal, the insulating shell 1 is made of a composite material with high wear resistance and good insulation. The outer surface of the insulating shell 1 is marked with an installation serial number.

[0033] The working principle and usage process of the present utility model: After the present utility model is installed, when it is necessary to insulate and protect the copper wires exposed at the joint position of two wires, the device is sleeved on the surface of the wires in advance. After the two wires are connected, the device is then pushed to the joint position. Then, the staff rotates the rotating handle 2 to drive the threaded rod 3 to rotate. When the threaded rod 3 rotates, it will cooperate with the sliding rod 10 to move downward. At this time, the downward movement of the threaded rod 3 can drive the pushing plate 5 rotatably clamped on its surface to move downward. When the pushing plate 5 moves downward, it will pull the swing rod 6 to swing around the pin shaft through the pin shaft. The swing of the swing rod 6 can drive the clamping sleeve 7 to move towards the position of the mating sleeve 18, so as to clamp and insulate and protect the joint position of the wires, prevent the copper wires inside the wires from being exposed outside, and have high safety.

[0034] Due to the cooperation between the thread above the threaded rod 3 and the threaded sleeve 9, the stability of the clamping of the joint position of the wires by the clamping sleeve 7 and the mating sleeve 18 can be improved, preventing loosening and affecting the use of the wires. At the same time, since insulating protection pads 8 are provided on the inner sides of both the clamping sleeve 7 and the mating sleeve 18, the copper wires can be further insulated and protected, and it will not affect the heat dissipation effect of the joint position during the use of the wires.

[0035] At the same time, when the pushing plate 5 moves downward, it will drive the sliding rod 10 to move downward. The movement of the sliding rod 10 can pull the rack 12 downward through the connecting plate 11. The movement of the rack 12 meshes and drives the gear 13 to rotate. The rotation of the gear 13 can drive the mating block 14 on the surface of the transmission rod 17 to rotate. When the mating block 14 rotates to a certain position, it can push the two clamping rods 15 to swing in the opposite direction around the pin shaft. The swing of the clamping rods 15 can drive the limiting sleeve 16 to clamp the position of the non-exposed copper wires of the wires. Due to the anti-slip pad provided on the inner side of the limiting sleeve 16, the friction between the limiting sleeve 16 and the surface of the wires can be increased, preventing the joint position from loosening due to external reasons during the long-term use of the two wires, and effectively improving the safety during the installation and use of the wires.

[0036] And because the installation serial numbers are written on the surface of the insulating shell 1, it is convenient for maintenance personnel to quickly repair or remove the wires, with high work efficiency. When maintenance or removal is required, only by rotating the rotating handle 2 in the reverse direction can the joint position of the wires be loosened. Then, after the insulating shell 1 is pushed away, the joint position of the wires will be exposed again, facilitating the maintenance or removal by the maintenance personnel.

[0037] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
