Description

Technical Field

[0001] This invention relates to an insulated wire clamping mechanism. Background Technology

[0002] Insulated conductors consist of an insulating sheath and a conductor. The main functions of the insulating sheath are electrical insulation, waterproofing, and moisture protection. The main functions of the conductor are to provide mechanical properties and current conduction. There are generally two methods for fixing existing overhead conductors: 1. Removing the insulation from the conductor and anchoring it to the tower can achieve good mechanical properties, but removing the insulation affects the conductor's insulation and waterproof / moisture-proof performance, thus reducing the overall design quality of the line.

[0003] 2. Directly anchoring the insulation and conductor together is problematic because the mechanical properties of the insulation and conductor differ too much. In practical applications, existing products may cause the insulation and conductor to separate, failing to achieve the intended mechanical force and thus creating greater safety hazards. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an insulated wire clamping mechanism that anchors the insulation and conductor together. During the installation of the clamping mechanism, a pre-tightening force is added, which is converted into frictional force between the insulation and conductor, thus preventing separation between the insulation and conductor.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: an insulated wire clamping mechanism, comprising a main body, on which a bracket and a through hole penetrating both ends are provided. Two clamping plates are located within the through hole, clamping the wire between them. The mechanism also includes a pressing block and a locking bolt. One end of the pressing block extends into the through hole, and the upper and lower sidewalls of the pressing block respectively contact one of the clamping plates and the inner wall of the through hole. A baffle is also included, fixed to the main body. The locking bolt passes through the baffle and connects to a screw hole on the pressing block. Rotating the locking bolt causes the pressing block to slide within the through hole. As the pressing block slides into the through hole, it pushes the two clamping plates closer together, clamping the wire. This mechanism, by rotating the locking bolt, allows adjustment of the clamping force between the clamping plates and the wire. This clamping force can be converted into frictional force between the insulation and the conductor, preventing separation between the insulation and the conductor. This solution preserves the insulation of the wire while preventing separation between the insulation and the wire.

[0006] Preferably, the width of the through hole gradually increases from one end to the other, and the clamping block is inserted into the through hole from the end with the larger width. The thickness of the clamping block gradually increases from the end inserted into the through hole. By rotating the locking bolt, the clamping block is driven into the through hole. As the thickness increases, the surface of the clamping block in contact with the clamping plate moves closer to the center of the through hole, thus bringing the two clamping plates closer together and clamping the wire.

[0007] Preferably, the thickness of one of the clamping plates in contact with the inner wall of the through hole gradually increases from one end to the other, with the thinner end located at the end with the narrower through hole width. This design allows the tension on the wires after installation to pull the clamping plate forward along the narrower end of the through hole, resulting in a more secure connection between the wires and the device.

[0008] In one embodiment, the baffle and the narrowest end of the clamping block are positioned opposite each other. In this configuration, when the locking bolt rotates, pulling the clamping block into the through hole, the clamping plates move closer together.

[0009] In another configuration, the baffle and the widest end of the clamping block are positioned opposite each other. In this configuration, when the locking bolt rotates, pushing the clamping block into the through hole, the clamping plates move closer together.

[0010] Preferably, the inner wall of the clamping plate is provided with strip-shaped protrusions, which contact the wire and are arranged laterally. The strip-shaped protrusions increase the clamping force between the clamping plate and the wire, preventing slippage between them.

[0011] Preferably, the bracket includes two strip plates, one end of which is connected to the main body by a first bolt, and the other end of which is located outside the main body. A second bolt passes through the other ends of the two strip plates and is connected to a nut.

[0012] The beneficial effects of this invention are: this mechanism can adjust the clamping force between the clamping plate and the conductor by rotating the locking bolt. This clamping force can be converted into frictional force between the insulation and the conductor, which can prevent the insulation and the conductor from separating. This solution preserves the insulation of the conductor while preventing the insulation and the conductor from separating. Attached Figure Description

[0015] Figure 3 This is a schematic diagram of the structure of Embodiment 2 of the present invention. Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: Example 1, see Figure 1-2 An insulated wire clamping mechanism includes a main body 1, on which a bracket 2 is provided. The bracket 2 includes two strip plates 21. One end of each strip plate 21 is connected to the main body 1 by a first bolt 22, and the other end of each strip plate 21 is located outside the main body 1. A second bolt 23 passes through the other ends of the two strip plates 21 and is connected to a nut 24.

[0017] The main body 1 is provided with a through hole 11 that extends through both ends, and the width of the through hole 11 gradually increases from one end to the other.

[0018] The through hole 11 contains two clamping plates 3, which clamp the wire 4. A strip-shaped protrusion 31 is provided on the inner wall of each clamping plate 3, contacting the wire. The strip-shaped protrusion is horizontally oriented. This protrusion increases the clamping force between the clamping plate and the wire, preventing slippage. The thickness of the clamping plate 3 in contact with the inner wall of the through hole gradually increases from one end to the other, with the thinner end located at the end with the narrower through hole width. This design allows the tension on the wire after installation to propel the clamping plate forward along the narrower end of the through hole, resulting in a more secure connection between the wire and the device.

[0019] It also includes a clamping block 5 and a locking bolt 6. The clamping block 5 is inserted into the through hole 11 from the wider end of the through hole 11, and the thickness of the clamping block 5 gradually increases from the end inserted into the through hole 11. The lower side wall of the clamping block 5 is in contact with the inner wall of the through hole, and the upper side wall of the clamping block 5 is in contact with the clamping plate 3 below.

[0020] It also includes a baffle 7, which is fixed to the main body 1 and is positioned opposite the narrowest end of the clamping block 5. In this configuration, when the locking bolt rotates, it pulls the clamping block into the through hole, causing the clamping plates to move closer together. The locking bolt 6 passes through the baffle 7 and connects to a screw hole on the clamping block 5. Rotating the locking bolt causes the clamping block to slide within the through hole. As the clamping block slides into the through hole, it pushes the two clamping plates closer together, clamping the wire.

[0021] This mechanism, by rotating the locking bolt, moves the clamping block into the through hole. As the thickness increases, the contact surface between the clamping block and the clamping plate gets closer to the center of the through hole. This brings the two clamping plates closer together, adjusting the clamping force between the clamping plates and the wire, thus clamping the wire securely. This clamping force can be converted into frictional force between the insulation and the conductor, preventing separation between them. This design preserves the insulation of the wire while preventing separation between the insulation and the wire.

[0022] Example 2, see Figure 3 The baffle 7 and the widest end of the clamping block 5 are positioned opposite each other. In this way, when the locking bolt rotates, it pushes the clamping block into the through hole, causing the clamping plates to move closer to each other. The rest is the same as in Embodiment 1.
