Description

A kind of low voltage switchboard master clamps

Technical field

The utility model relates to master clamp fields, in particular to the master clamp field of low-voltage distribution cabinet complete set of equipments.

Background technique

Conventional low voltage switchboard master clamps at present, usually sheath, is lifted on cabinet top for busbar.Such arrangement There are various problems.First, due to the principle that hot-air radiates upwards, component heat usually radiates toward cabinet top in cabinet, Busbar is also arranged in cabinet top, is exactly on hot-air heat dissipation channel, is highly detrimental to busbar heat dissipation in this way.Second, it will be female Arrangement is placed in cabinet top, can occupy cabinet body short transverse space, causes height space nervous.Third, conventional master clamp generally can only Rectangle busbar is installed, the busbar of c-type or other shapes can not be suitable for.

Chinese patent 201310749256.8 discloses a kind of master clamp, provide one kind can in busbar width direction and The busbar that thickness direction simultaneously clamps on, including at least one unit master clamp；The unit master clamp include two structures it is identical, The primary and secondary row folding of horizontal symmetrical setting, the primary and secondary row folding includes at least two insulation being stacked together in the vertical direction Block, the upper part of each collets side and end portion are provided with step positioning surface, between two adjacent collets Step positioning surface surround the groove for blocking busbar in the horizontal direction, two horizontal planes up and down of the groove jointly The distance between be adapted with the thickness of busbar；It is vertically provided on each collets in primary and secondary row folding described in two logical Hole, and the upper and lower of each primary and secondary row folding is provided with a fitting, the fitting is the connector of sheet, including is linked together Horizontal component and vertical portion, be provided with hole on the horizontal component of each fitting；First stud will be in a sub- master clamp All collets and two fittings of lower section disposed thereon are worn together, and are fixedly clamped with two nuts, and the second stud will be another Two fittings of all collets and lower section disposed thereon in one sub- master clamp are worn together, and are fastened with two nut clips It is fixed；It is also provided with hole in the vertical portion of the fitting, is led between the vertical portion of two fittings of primary and secondary row folding the same side It crosses third stud and two nuts links together；It is parallel to each other or is arranged vertically between multiple unit master clamps, and It is connected between two adjacent unit master clamps by the way that adjacent fitting to be linked together.

The vertical plane being in contact in the groove with the vertical side of busbar is the cambered surface of evagination, when busbar expands with heat and contract with cold, The size and change in displacement of busbar are adapted to the vertical plane in above-mentioned groove in radian；First stud and engaged therewith two A nut is replaced with first bolt and a nut；Second stud and two nuts engaged therewith are with one second Bolt and a nut replace；The third stud and two nuts one third bolt and a nut generation engaged therewith It replaces；Collets in the primary and secondary row folding are made of flexible insulating materials.

But the common making material of this structure master clamp is hard insulation, so biggish vibration can be generated Noise not only interferes surrounding people, also will affect the safe operation of equipment；In addition, the versatility of common master clamp is non- Often it is poor, for the busbar of feature specification, specific configuration mode, it is necessary to be equipped with specific master clamp, if change busbar specification or Arrangement mode must then replace master clamp, carry out inconvenience to the work belt for purchasing and managing busbar.

Summary of the invention

The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of low voltage distribution cabinet bus-bar Folder, specifically, in order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is as follows: the utility model includes Integrally formed master clamp is contained at least two, the master clamp is fixed on frame by the fixed support of master clamp, the mother Row folding is set to the rear of low-voltage distribution cabinet, and the master clamp is fixedly connected with rectangle busbar or c-type busbar.

Further, the master clamp is fixed in the fixed support of master clamp by fixed screw, the fixed branch of the master clamp Part is connected on distributing cabinet frame.

Further, it is connected with master clamp between the master clamp and frame and reinforces support.

Further, the distributing cabinet frame is the frame for being installed on power distribution cabinet rear.

Further, the master clamp includes at least 1 group of rectangle busbar or c-type busbar.

Further, the rectangle busbar or c-type busbar are fixed on master clamp by busbar fixed screw.

Further, the master clamp material is nylon.

Further, nut inserts, busbar card slot are contained on the master clamp；The nut inserts is hexagon, is located at The master clamp upper end；The busbar card slot be rectangle, be located at the master clamp lower end, busbar card slot in pairs, with nut Inserts is distributed across master clamp both ends.

The beneficial effects of the utility model are as follows:

1. using this master clamp, after busbar is located at cabinet, above busbar without any blockage, it is conducive to busbar and radiates.

2. using this master clamp, after busbar is located at cabinet, it is not take up cabinet body short transverse space.

3. master clamp can install rectangle row and install c-type row.
