fig. 2 is the utility model discloses a repeatedly usable's safe get electric fastener device get the electric operation when putting into the cable at the entering schematic diagram.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments:
referring to fig. 1, the utility model discloses a reusable safe power line clamp device, including plastic housing 1, square pipe mount 2, cable bush 3 and get the electricity 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.
