Abstract
The utility model provides a distributing cable branch device, which is characterized in that: the device comprises a U-shaped clip plate frame, a sealing block, a fastening screw and a spacer, and has the advantages of firm press fastening, no space between the main cable and the branch cable, small contact resistance and less power loss. The utility model can conveniently replace branch cable, and is a more ideal improved replacement product for low voltage distributing cable branch device.
Description
The utility model relates to the used device of a kind of distribution cable branch line, is the improvement to existing branch cable device.
In the installation of power supply facilities, the branched line of low-voltage distribution cable usually is necessary, tell branch line from backbone, people adopt the cable branch device, at present, use branch unit (shown in Figure 1), by two conduction clamping plate 1, fastening nut 2 will be dominated cable 6 and branch cable 7 is clipped between the conductive clip, this device is because the electric current of leading cable is to be delivered on the branch cable by clamping plate, clamping plate are generally copper product, and its contact resistance is bigger like this, has increased line loss, easily generate heat, and be easier to scaling loss and destruction in its clamp portion.
The purpose of this utility model is the deficiency that overcomes above-described branch unit, makes improvements, and provides that to have a contact resistance little, and is few with electrical loss, safeguards and changes a kind of easily cable branch device of branch cable.
Distribution cable branch unit of the present utility model be achieved in that it by the clamping frame of " U " type, pad, envelope piece, fixedly clamping frame and envelope piece screw, and housing screw etc. form.The envelope piece is contained in the opening part of clamping frame with screw, on the envelope piece 2 to 3 screws that are used for compress gasket is housed.Leading cable and branch cable are close together, in the clamping frame and pad of " U " type, by housing screw extruding spacers.
The distribution cable branch unit that the utility model provides owing to adopted " U " type clamping frame, and will be dominated cable and be close to branch cable, compress fastening, so it is little that it has a contact resistance, with the few advantage of electrical loss.And can change branch's electrical cables easily, be that the existing cable branch unit improves.
Below in conjunction with description of drawings embodiment of the present utility model.
Fig. 1 is original cable branch device schematic diagram;
Fig. 2 is that " U " type clamping frame type cable branch device is installed and used schematic front view;
Fig. 3 is that " U " type clamping frame type cable branch device is installed vertical view.
Fig. 2, Fig. 3 distribution cable branch unit, it is by the splint holder 1 of " U " type, is fastened on the envelope piece 4 of " U " clevis grillage opening part, the backing plate 3 in the splint holder of " U " type, and the compositions of adorning such as trip bolt 2 with counter-sunk screw 5 on the envelope piece.It uses installation method is that the locational insulating barrier that will dominate cable 6 required branch cables is earlier peelled off, expose the lead nude, again " U " type clamping plate are buckled on the leading cable, to the end socket of pinching screw be housed, be fixed on " U " type clamping plate opening part with counter-sunk screw, and after the termination of branch cable 7 removed insulating barrier, insert leading cable place and with " U " molded lines folder and be close to, in envelope piece 4 and leading cable, insert backing plate, get final product with trip bolt is fastening.At last, carry out insulation processing.
If will change branch cable,, tighten trip bolt then as long as loosening trip bolt is extracted the branch cable that is changed out and inserted new branch cable.Just can finish.So the maintain and replace branch cable is very convenient.
Claims (1)
1, a kind of distribution cable branch unit, formed by clamping plate (1), trip bolt (2), backing plate (3), it is characterized in that described clamping plate are " U " type splint holder, at the opening part of " U " type splint holder an envelope piece (4) is installed, and will be sealed piece with counter-sunk screw (5) and be fixed on " U " type splint holder; Described fastening screw cylinder has two at least, with " U " type splint holder with seal that piece is fastening to be combined; Described backing plate is placed in " U " splint holder under the trip bolt.
