Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific examples:
referring to fig. 1, the reusable safe power line clamp device of the present invention includes a plastic housing 1, a square tube fixing frame 2, a cable bushing 3 and a power structure. The electricity taking structure is composed of a clamping screw 41, a screw support 42, a support plate 43 and a cable socket 44.
The plastic shell 1 is of a splicing structure, the safe power cable clamp device forms closed cladding after splicing is completed, and an opening for placing the cable bushing 3 is formed in the end portion of the safe power cable clamp device. The plastic shell 1 is designed to be suitable for being held by an operator, and is safe and convenient to operate. The square tube fixing frame 2 is arranged in the plastic shell 1 and used for supporting the cable bush 3 and the power taking structure.
The cable bush 3 is a circular arc surface structure, one end of the circular arc surface structure is provided with a cable limiting structure 31, and the other end of the circular arc surface structure is provided with a power taking open groove 32. The cable bush 3 is rotatable and detachable joint is on square pipe mount, and the cable bush 3 to the different models of cable matching of not unidimensional carries out stable fixed in order to treat to get the electric cable. The cable bush 3 disperses the stress of the cable when the clamping screw 41 is pressed into the cable, and reduces the deformation of the cable. The cable bush 3 is clamped in the fixing frame after being put into the cable and rotated to the position, and the cable limiting structure 31 ensures that the cable cannot be separated upwards when the tip of the clamping screw 41 is pressed into the cable.
The electricity taking structure is arranged inside the plastic shell. The clamping screw 41 is supported by the screw support 42 and the support plate 43, and the tip end of the clamping screw faces the cable bush 3, extends into the electricity taking open groove 32 of the cable bush 3, and is limited by the electricity taking open groove 32. The end part of the clamping screw rod 41 is of a spherical structure, so that the copper core wires are extruded as far as possible when the tip contacts the copper core of the cable, the tip is extruded between the copper core wires, and the effective electricity taking load can be ensured when the stroke of the tip part reaches the center of the cable. The tail end of the clamping screw 41 is of an inner hexagonal structure, and an opening facing the operation socket is formed in the plastic shell and used for rotating the locking screw 41 through an inner hexagonal insulation wrench. The clamping screw 41 is rotated by the screw structure while being displaced relative to the cable bushing 3, thereby being squeezed between the cable copper cores.
