Description

Technical Field

[0001] The utility model relates to the field of insulating wire clamps, and particularly to a novel insulating piercing wire clamp. Background Art

[0002] The insulating piercing wire clamp, as a key connection tool in the power system, has the unique advantage that it can connect the branch of the cable main line without damaging the cable insulation layer, thereby improving the stability of electrical connection and installation efficiency. However, although it is widely used to fix insulated wires and ensure the reliability of power transmission, some problems have also emerged in practical applications, especially in terms of adaptability when dealing with different wire surfaces.

[0003] Specifically, the insulating piercing wire clamp realizes fixation by piercing the wire insulation layer with a piercing needle 17. This method will inevitably cause certain damage to the wire surface. For wires with relatively soft textures, such as plastic sheathed wires and rubber insulated wires, the piercing needle 17 may cause more significant surface damage, thereby affecting the insulation effect and service life of the wire. Under extreme environmental conditions, such as high temperature, high humidity or strong ultraviolet radiation, this surface damage may accelerate wire aging and reduce its overall reliability.

[0004] To ensure the firm fixation of the wire, the piercing needle 17 needs to have sufficient sharpness and strength, but this further increases the potential risk of damage to the wire surface. Therefore, when using an insulating piercing wire clamp, it may be necessary to regularly inspect the wire and replace it when necessary, which undoubtedly increases the maintenance cost. More seriously, surface damage may cause safety accidents such as wire short circuits or fires in extreme cases, posing a threat to the operation of the power system. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a novel insulating piercing wire clamp, which can effectively solve the problems raised in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A novel insulating piercing wire clamp includes a first insulating wire clamp, a second insulating wire clamp, mounting holes and a connecting device. The first insulating wire clamp and the second insulating wire clamp are connected by the connecting device. The first insulating wire clamp and the second insulating wire clamp are provided with wire grooves for inserting wires. The first insulating wire clamp and the second insulating wire clamp are connected by a locking device;

[0008] The first insulating wire clamp includes two half hoop bodies. The two half hoop bodies are connected by a connecting device to form a circular hoop body. Embedding grooves are formed on the side walls of the two half hoop bodies. A rubber anti-slip cover is embedded and connected in the groove of the embedding groove. The rubber anti-slip cover protrudes inward to abut against the wire in the wire groove to achieve fixation;

[0009] A bending and pressing strip is installed at the outer opening of the embedding groove, and a plurality of reinforced springs are installed on the inner wall of the bending and pressing strip.

The rotating shaft sleeve is located at the tail of the screw rod, and the rotating shaft sleeve is sleeved on the opening rotating shaft of the half hoop body. The two half hoop bodies are connected by rotating the nut;

[0011] As a further optional solution of the present invention, the cross-section of the rubber anti-slip cover is designed in a "C" shape. The rubber anti-slip cover is adapted to the embedding groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, the design of the bending and pressing strip can better press the wire, ensuring that the wire does not slide in the wire groove, thereby improving the fixing effect of the wire.

The design of the puncture needle allows for easy disassembly and replacement, which is convenient for maintenance and repair.

[0018] The rubber anti-slip cover has good anti-slip performance, can tightly hold the wire in the wire groove to prevent the wire from sliding.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 4 As shown, a novel insulated piercing wire clamp is mainly composed of a first insulated wire clamp 1, a second insulated wire clamp 2 and a connecting device 3. The two large insulated wire clamps are tightly connected together by the connecting device 3, and together constitute the main structure of the wire clamp. They are each designed with a wire groove 5, which is designed to facilitate the insertion and fixation of the wire. In order to achieve a stable connection of the wire clamp, a locking device 4 is cleverly used between the first insulated wire clamp 1 and the second insulated wire clamp 2.

[0026] Specifically, the first insulating wire clamp 1 is composed of two carefully designed half-side hoop bodies 11. The two half-side hoop bodies 11 can be tightly connected into a ring-shaped hoop body through the ingenious action of the connecting device 3. In order to further enhance the fixing effect of the wire, the side wall of each half-side hoop body 11 is ingeniously provided with an embedding groove 12. In these embedding grooves 12, we embed rubber anti-skid covers 13. These rubber anti-skid covers 13 not only have good anti-skid performance, but also can be designed to protrude inwardly, tightly against the wire in the wire trough 5, thereby achieving stable fixation of the wire.

[0027] At the outer opening of the embedding groove 12, we have especially installed the bending and pressing strips 14. Inside walls of these bending and pressing strips 14 are equipped with multiple reinforced springs 16. The powerful elastic force of these springs can push the puncture needles 17 at their inner ends through the rubber anti-slip cover 13 and further pierce into the wire, thus realizing the double fixation of the wire. This design not only improves the fixation effect of the wire but also makes the wire clamp safer and more reliable during use.

[0028] The design of the locking device 4 is equally ingenious. It mainly consists of a rotating shaft sleeve, a screw rod, and a nut. The rotating shaft sleeve is ingeniously sleeved on the opening rotating shaft of the half hoop body 11, and the screw rod passes through the corresponding holes of the two half hoop bodies 11. By rotating the nut, we can easily connect the two half hoop bodies 11 tightly together. This design not only simplifies the installation process of the wire clamp but also improves the stability of its connection.

[0029] In addition, the cross-section of the rubber anti-slip cover 13 adopts a unique "C" - shaped design. This design enables the rubber anti-slip cover 13 to better fit the embedding groove 12 and can more tightly press against the wire. At the same time, the rubber anti-slip cover 13 and the bending and pressing strips 14 are connected by an adhesive, further enhancing the stability of their connection. The bending and pressing strips 14 are made of bendable metal plates, and their protruding design towards the center of the wire groove 5 can better press against the wire. In order to reduce the wear on the half hoop body 11, rubber gaskets are provided at the contact ends of the bending and pressing strips 14 and the half hoop body 11.

[0030] During the installation process, we only need to insert the bending and pressing strips 14 through the installation holes 15 into bolts and fix them on the half hoop body 11. In order to facilitate the removal and replacement of a single puncture needle 17, a stop block is designed at the tail of the puncture needle 17, and the reinforced spring is welded to the stop block. At the same time, the reinforced spring and the bending and pressing strips 14 are also fixed by bolts. This design enables us to easily carry out the disassembly and replacement work when the puncture needle 17 needs to be replaced.

[0031] Usage process: Confirm that the first insulating wire clamp 1 and the second insulating wire clamp 2 are intact, and the connecting device 3, the locking device 4, and other components are complete. Prepare the wire to be fixed, ensure that the wire is not damaged, and measure its diameter to match the wire groove 5.

[0032] Place the two half hoop bodies 11 on both sides of the wire respectively, ensuring that the wire groove 5 is aligned with the wire. Place the connecting device 3 between the two half hoop bodies 11 and adjust it as needed so that it can tightly connect the two half hoop bodies 11.

[0033] Gently push the wire into the wire groove 5 to ensure the correct position of the wire. Check whether the rubber anti-slip cover 13 has been correctly embedded in the embedding groove 12 and ensure that its "C" - shaped design closely fits the wire.

[0034] Insert the bent clamping strip 14 through the mounting hole 15 into the bolt and fix it on the half hoop 11. Ensure that the inner wall spring 16 of the bent clamping strip 14 faces the wire. Adjust the position of the bent clamping strip 14 so that the puncture needle 17 on its inner wall is aligned with the wire and prepare for puncture fixation.

[0035] Rotate the nut to tightly connect the two half hoops 11 together through the locking device 4 to form a circular hoop. As the nut rotates, the bent clamping strip 14 moves inward under the push of the spring 16, causing the puncture needle 17 to pass through the rubber anti-slip cover 13 and pierce into the wire, achieving double fixation.

[0036] Check whether all components are installed in place to ensure there is no looseness or omission. Observe whether the wire is firmly fixed and make fine adjustments if necessary.

[0037] After confirming that the wire has been firmly fixed, it can be regarded as the installation is completed. If it is necessary to replace the puncture needle 17, the old puncture needle 17 can be easily removed and a new puncture needle 17 can be replaced by disassembling the stopper and the bolt. During the whole using process, attention should be paid to safe operation to avoid electric shock or injury. At the same time, the state of the insulating puncture wire clamp should be checked regularly to ensure it is in good working condition.
