Abstract

A wire distribution device used in a two-line, three-line, four-line and five-line system multi-core power cable comprises a U-shaped cut framework (1), a movable sealing block (2). The device is also characterized in a axle (3), a pin (4), a brand wire (10) terminal wiring plate (5), a fastening bolt (6), a main cable (9), a pressing bedding block (7), a pressing bolt (8), and an insulating base (1) etc. The wire distribution can be done without cutting off the main cable during the wire distribution process, and the utility model is low in power distribution failure, easy in installation and repair, minimum in occupied space, small in power distribution box volume, and is suitable to be used in various power distribution of low voltage electric equipments.

Description

A kind of multi-core power cable branch means

The utility model belongs to cable-clamping device, specially refers to branch line required distribution cable branch means in many places in a kind of multi-core power cable major loop.

Adopt multi-core power cable at existing power supply facilities mesolow distribution, the mounting means that its branched line adopts usually is to adopt " π " type connection to finish from backbone.Leader cable needs to cut off like this, and the needed casing of branched line is bigger, and in installation because leader cable cuts off installation to be reconnected, cable need have certain consumption.In addition, this installation increases the leader cable contact, makes the failure rate that produces rise.Maintenace point increases, and it is bigger to take up room, and the total consumption expense is also bigger.

The purpose of this utility model is the deficiency that overcomes existing above power supply low-voltage distribution branch line technology, its function is applicable to the multi-core power cable branch means, to the further improvement and perfect of above low-voltage cable branch unit, provide a kind of being suitable for to use in the low pressure branch line case, need not to cut off leader cable, failure rate is low in the use, is convenient to maintenance and repair, the multi-core power cable branch line device that takes up room little.

A kind of multicore cable branch means provided by the utility model comprises " U " type open stand, movable envelope piece, and its characteristics also have axle, pin, branch wire terminal connections plate and fastening bolt, and leader cable compresses cushion block and hold-down bolt.Have the groove of placing leader cable in the middle of described " U " type open stand, with pin piece is sealed in activity by axle on it and be connected, and be fixed on the opening part of " U " type support.On activity envelope piece, adorning 2 to 3 hold-down bolts that compress leader cable.Cushion block is under its hold-down bolt, and described branch wire terminal fishplate bar is loaded in " U " type open stand, and the position under the leader cable has at least two branch line wiring to compress screw and bolt on it.

A kind of multi-core power cable branch means of the following stated also is equipped with the insulating base of " L " type or " " type below its " U " type open stand.

Enforcement by a kind of multi-core power cable branch means of the utility model, have easy to install, need not to cut off leader cable, stock utilization improves, reduced the volume of branch line low-tension distribution box, fault is few, and maintenance and repair are convenient, advantages such as it is little to take up room, the use of the branch line distribution box of applicable multi-core power cable.It is applicable to two-wire system, three-wire system, three-phase four-wire system, three-phase five-wire mode etc., is loaded in the distribution box, tells some line loops.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the mounting structure master schematic diagram of multi-core power cable branch means;

Fig. 2 is the mounting structure end view of multi-core power cable branch means;

Fig. 3 is that one in the multi-core power cable installs vertical view mutually;

Fig. 4 is mounted in the multicore cable branch means scheme of installation in the distribution box.

Fig. 1, Fig. 2 and Fig. 3, the multi-core power cable branch means comprises " U " type open stand, movable envelope piece 2, axle 3, pin 4, branch line terminal terminal block 5 and fastening bolt 6, leader cable compress cushion block 7 and hold-down bolt 8.Have the groove of placing leader cable 9 in the middle of described " U " type open stand, by axle and pin piece sealed in activity it on and connect, and be fixed on the opening part of " U " type support, will sell extract out after the activity of can opening seal piece, it is enclosed within on the leader cable.Adorning 2 to 3 hold-down bolts that compress cable core on activity envelope piece, cushion block is settled under its hold-down bolt.Described branch wire 10 terminal connections plates 5 are loaded in " U " type open stand, the position under the leader cable, and what have on it that four branch line wiring use compresses screw and bolt.In addition, the insulating base 11 of a protection side and bottom surface is housed also below " U " type open stand, it is shaped as " L " type or " " type, and is fixed on countersunk bolt under the base plate of " U " type open stand.

Fig. 4 is mounted in multi-core power cable 13 branch means in the distribution box 12, and multi-core power cable enters separated time O, A behind the distribution box, B, C, five main lines of PE, i.e. three-phase five-wire mode distribution.What branch means adopted is " L " type insulation board, installs and uses side by side in distribution box.Every group of main line can be told the 1-4 loop by the separated time fishplate bar.Thereby make the wiring compactness in the distribution box, the taking up room of the distribution box that reduces.The connection of its branch line is very convenient with replacing.

Axle 3 and pin 4 described in the multi-core power cable branch means provided by the utility model, can exchange, also can adopt two bearing pins, as long as extract an axle out, piece is sealed in the rotation activity during use, open it, can pack into the leader cable that removes insulation sheath in this device, close movable envelope piece then, put on bearing pin, adjust hold-down bolt, just can finish the whole erection process.For this reason, it is the improvement of existing branch means.Be applicable to that backbone separated times such as two lines, three-way, four lines and five-wire system use.
