Abstract
The utility model provides a live-wire operation irregular parallel groove clamp comprising an upper cover and a lower cover which are fastened and buckled through bolts. Matching surfaces of the upper cover and the lower cover are provided with a main line clamping mouth and a branch line clamping mouth. Two side walls of the upper cover next to the branch line clamping mouth are fixed with convex pins, and branch line binding fixed points are formed. According to the live-wire operation irregular parallel groove clamp, the pins can be used as the fixed points, a branch line is bound into the branch line clamping mouth at the upper cover in advance on the ground, the connection reliability of the branch line is very high, through only using an electric power special tool to lift the clamp and the branch line to a main line to be fastened, live-wire operation can be realized, normal power transmission is not affected, and operation efficiency is raised.
Description
Technical field: the utility model relates to wire-connection and the branch's gold utensil, particularly a kind of parallel groove clamp that a kind of power overhead network is used.
Background technology: in built on stilts electrical lead connects, often need to use parallel groove clamp branch from main line to connect and draw branch line.All be that upper and lower cover is unclamped during common parallel groove clamp attended operation, main line and branch line are put into respectively rear fastening clamping in main line jaws and the branch line jaws, this mode must personnel can guarantee wiring quality near manual operations, for safety work, must will carry out after the main line outage, the not only normal transmission of electricity of impact, operating efficiency is low, and the connection reliability of branch line is also not ideal enough.
Summary of the invention: for the deficiencies in the prior art, the utility model provides a kind of branch line to connect reliable live line working Special-shaped parrel-slot cable clamp.
The utility model comprises two loam cake and the lower covers that fasten by bolted, and the mating surface of loam cake and lower cover is provided with main line jaws and branch line jaws, all is fixed with the pin of evagination at the place, loam cake two side on branch line jaws next door, consists of branch line binding fixing point.
The utility model can utilize pin as fixing point, to prop up in advance line tying is bundled in the branch line jaws of loam cake on ground, the connection reliability of branch line is very high, then only need to use the electric power specific purpose tool that wire clamp is recommended main line place and fastening getting final product together with branch line, can realize live line working, do not affect normal transmission of electricity, improve operating efficiency.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the perspective view of embodiment.
Fig. 2 is the connection status schematic diagram of Fig. 1.
Fig. 3 is the front view of Fig. 2.
Embodiment: as shown in the figure, loam cake 1 and lower cover 2 are by bolt 3 fastening fastenings, the mating surface of loam cake 1 and lower cover 2 is provided with main line jaws 4 and branch line jaws 5, all is fixed with the pin 6 of evagination at the place, loam cake 1 two side on branch line jaws 5 next doors, consists of branch line 12 binding fixing points.During actual the use, in advance branch line 12 usefulness bands 13 are tied up in the branch line jaws 5 that is bundled in loam cake 1 around pin 6 on ground, re-use the electric power specific purpose tool whole wire clamp is recommended main line 11 places together with branch line 12, sandwich in the main line jaws 4 main line 11 and fastening getting final product, need not to disconnect main line 11 electric currents, can live line working.
Present embodiment is provided with boss 7 at the top of loam cake 1, and the both sides of this boss 7 are provided with groove 8, and the formation instrument is recommended groove, and it is more convenient to use like this electric power specific purpose tool to recommend wire clamp.Between bolt 3 heads and lower cover 2, also be lined with pressing plate 9 and packing ring 10, make loam cake 1 and lower cover 2 fastening fastenings more reliable and more stable.
