In this embodiment, the deformation portion 121 may be deformed by hot melting to shrink so as to clamp the ground wire, and since the deformation portion 121 deforms and then the main body portion 110 is involved to deform, in order to ensure structural strength, the reinforcing portion 130 is embedded in the main body portion 110, and the melting point of the reinforcing portion 130 is higher than that of the main body portion 110 and the clamping portion 120, so that the deformation portion 121 is deformed by hot melting, the reinforcing portion 130 is not deformed greatly, and the strength of the whole fixture is maintained in an ideal state, thereby ensuring the service life of the fixture.

As an alternative embodiment, the reinforcement portion 130 includes a supporting block 131, and a through groove that is matched with the supporting block 131 is formed in the main body portion 110.

In the present embodiment, since the reinforcing portion 130 and the main body portion 110 have different melting points, the reinforcing portion and the main body portion are manufactured separately and assembled, and thus the support block 131 can be inserted into the through groove of the main body portion 110 by forming the through groove in the main body portion 110, which is convenient and quick to assemble. Here, the upper and lower edge horizontal lines of the supporting block 131 should exceed the upper and lower vertex horizontal lines of the clamping groove 122, so that the deformation degree of the deformation part 121 can be born, and the overall strength of the clamp is ensured. Preferably, the left and right end surfaces of the supporting block 131 are equally spaced from the adjacent clamping grooves 122, i.e., the supporting block 131 is located at the center of the body 110, so that it is ensured that the contraction force is uniformly received.

If the fixture is placed horizontally, the supporting block 131 may be directly inserted into the through slot of the main body 110, and if the fixture is placed obliquely or vertically, a screw may be screwed to the main body 110, and a threaded hole matching with the screw is also formed at a position corresponding to the supporting block 131, so that the supporting block 131 is firmly fixed in the main body 110 by the screw.

In the present embodiment, the end surface area of the stopper 132 is larger than the end surface area of the reinforcement portion 130, that is, the stopper 132 is limited to abut against the outer wall of the main body portion 110, so that the entire reinforcement portion 130 can be firmly fixed in the main body portion 110 without falling out of the main body portion 110.

As an alternative embodiment, the two limiting blocks 132 are integrally connected and/or detachably connected with the supporting block 131.

In the present embodiment, if the two limiting blocks 132 and the supporting block 131 are all integrally connected, the supporting block 131 can be inserted into the through groove of the main body 110 first, and then the limiting blocks 132 are welded on two sides of the supporting block 131, so as to form a firm and stable integral structure of the reinforcing part 130; if the two limiting blocks 132 and the supporting block 131 are both in detachable connection structures, after the supporting block 131 is installed, the two limiting blocks 132 are assembled at two ends of the supporting block 131 in a screw or glue joint mode; if one of the limiting blocks 132 and one end of the supporting block 131 are of an integral structure, the other limiting block 132 and the supporting block 131 are of a detachable structure, when the assembly is performed, one end of the supporting block 131, which is not provided with the limiting block 132, is aligned with the through groove and inserted into the main body 110, so that the limiting block 132 integrated with the supporting block 131 is attached to the outer wall of the main body 110, and then the other limiting block 132 is assembled at the other end of the supporting block 131 in a screw or glue joint mode, so that the operation is convenient and fast. The above three assembly forms may be selected according to practical circumstances, and should not be limited herein.

As an alternative embodiment, the deformation portion 121 is made of a heat-shrinkable material, so that the deformation portion 121 can be heated to deform and shrink by hot melting, and simultaneously, the two deformation portions 121 can be clamped by using an auxiliary tool, so that the opening of the clamping groove 122 is folded and reduced according to a certain shape, a solid structure with stable shape can be formed after the deformation portion 121 is cooled, deformation is not easy to occur under the condition of no high temperature, and the deformation amount and deformation convenience of the deformation portion 121 are better controlled by adopting a hot melting deformation mode, so that the penetrating ground wire has better wrapping property, good fitting property, current transmission and more firm and stable clamping structure after deformation.

Since the deformation portion 121 and the body portion 110 are integrally formed, the body portion 110 is also made of the same material as the deformation portion 121, and thus, the integral processing is facilitated.

As an alternative embodiment, the deformation portion 121 is made of red copper or oxygen-free copper, the red copper or oxygen-free copper has better thermal conductivity and electrical conductivity, the red copper or oxygen-free copper can be deformed after being heated, and the deformed red copper or oxygen-free copper has better strength and electrical conductivity, so that the use requirement is met. The material of the deformation portion 121 is preferably oxygen-free copper, and the conductivity is better.

As an alternative embodiment, the top and bottom surfaces of the main body 110 and the clamping portion 120 are provided with a plurality of bar-shaped grooves 140, and the length direction of the bar-shaped grooves 140 is perpendicular to the laying direction of the through ground wire.

In this embodiment, after the deformation portion 121 is subjected to hot melt deformation, a certain shrinkage effect is generated, and a certain shrinkage space can be reserved for the shrinkage effect by the arrangement of the strip-shaped groove 140, so that the deformation portion 121 can better generate the deformation effect.

As an alternative embodiment, the clamping portion 120 is disposed on one side of the main body 110, so as to form a one-side clamping structure, which is suitable for a scenario where only a through ground wire is laid on one side.

As another alternative embodiment, the clamping portions 120 are disposed on two sides of the main body 110, so as to form a double-sided clamping structure, which is suitable for a scenario of simultaneously laying through-wires on two sides, and it should be noted that the diameters of the two clamping grooves 122 of the double-sided clamping structure may be the same or different, so that through-wires with different cable diameters may be respectively clamped.

Therefore, the clamping devices of the single-side clamping structure and the double-side clamping structure can be prefabricated in advance, so that the clamping devices with corresponding specifications can be selected according to the actual laying condition of the through ground wire, and the application range is wide.

The foregoing description is only of the preferred embodiments of the present utility model, and is not intended to limit the scope of the utility model, but rather is intended to cover any equivalents of the structures or equivalent processes disclosed herein or in the alternative, which may be employed directly or indirectly in other related arts.
