Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
(embodiment 1)
The present embodiment when carrying out orientation and describing, with the direction of court of Fig. 1 institute for describe in front, with Fig. 1 institute towards side in the opposite direction for describe in rear, the left and right directions of Fig. 1 and above-below direction also for description in left and right directions.
See Fig. 1, the wedge strain resistance cable clamp of the present embodiment, form primarily of wire clip body 1, voussoir 2, briquetting 3 and connecting bolt 4.
See Fig. 2, the material of wire clip body 1 is aluminium alloy.The waist location of the front end face of wire clip body 1 is provided with the wedge groove 11 to being recessed into, and the right part front end face of wire clip body 1 is provided with the guide finger 12 stretched into from front to back in wedge groove 11.
