Abstract

The utility model discloses a bus connecting device, which belongs to the technical field of low-voltage power distribution equipment. The bus connecting device comprises a horizontal bus bar formed by four groups of horizontal buses (2) arranged in parallel, and the horizontal bus bar is lapped on two opposite bus frames (1) of a control cabinet. The bus connecting device is characterized in that two ends of each horizontal bus are provided with at least two holes; at junctions of the horizontal bus and the bus frames, bus stoppers (4) are mounted at horizontal bus hole B (7) through connecting parts, and horizontal bus holes A (6) are lapped with horizontal bus connectors (5) through connecting parts, thereby forming the bus connecting device. When in use, sectional buses are mounted on different control cabinets in a workshop correspondingly, and are linked by the horizontal bus connectors to form long bus bars on the field, thereby not only reducing requirement to size of working sites, but avoiding loss caused by frequent detachment of long bus bars, realizing product normalization better, saving labor and materials and increasing working efficiency.

Description

Bus connecting device

Technical field

The utility model belongs to the low-voltage distribution apparatus technical field, is specifically related to a kind of bus connecting device that uses in control cubicle.

Background technology

Because manufacturing with on-the-spot installation exercise of controller switching equipment separated, though therefore strict, standard execution production link, but still there is following limitation in the on-the-spot installation method of traditional bus:

1, because many station power distributions equipment will be connected, need be corrected to a horizontal line on the height, and the prerequisite that many station power distributions equipment connects is that workbench must be smooth, on-the-spot many station power distributions equipment that connects is wasted time and energy, and takies sizable work-yard.

2, the busbar of disjunctor cabinet is difficult for installing.To reserve the whole required space of busbar turnover in the many station power distributions equipment that in manufacturing process, links to each other earlier, and reference need load onto the long busbar of level in advance and install for vertical busbar the time, pull down the long busbar of level after having adorned again, carry out electroplating surfaces with tin and deal with the work; Because zinc-plated processing hot operation may make the long busbar distortion of copper level, needs the long busbar glacing flatness of trial assembly debugging level again, the long busbar packing of the level of pulling down is again at last installed to on-the-spot with cabinet.In addition, break, break the fixedly insulating part of busbar easily in on-the-spot the installation, need on-the-spot providing that the required space of long busbar is installed simultaneously.Therefore this conventional method dismounting bothers and wastes time and energy.

3, the vertical busbar difficulty in many station power distributions of configuration equipment is big.In configuration during vertical busbar, it is corresponding that vertical busbar and the hole that horizontal busbar overlaps are difficult to, even connect by force in the erecting bed, but so just cause vertical busbar and horizontal busbar loose contact.

Though above-mentioned traditional method can be finished the installation of control cubicle busbar, than higher, and can not guarantee whether moment and other parameter that busbar connects reach requirement to field condition, site requirements, the heating problem when busbar flows through big electric current later on hides some dangers for.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of simple, convenient, as to prevent horizontal bus row move left and right bus connecting device of manipulating, can vertical busbars all in the cabinet be connected, prevent to be out of shape the generation that causes accident because of horizontal busbar and vertical busbar bad connection generate heat after the work of disjunctor cabinet.

For achieving the above object, the utility model adopts technical scheme as described below:

A kind of bus connecting device comprises the horizontal busbar that four groups of horizontal bus be arranged in parallel and form, and described horizontal busbar is set up on control cubicle two relative bus frames; At least two holes are opened at described horizontal bus two ends respectively, and wherein at horizontal bus and bus frame joint, the bus retainer is installed by connector by horizontal bus perforate B place; Horizontal bus perforate A place overlaps the horizontal bus plug connector respectively by connector and forms bus connecting device.

Length is corresponding between the described bus connecting device, described horizontal bus length and control cubicle two relative bus frames.

Described bus connecting device, the two ends perforate of described horizontal bus is a circular hole.

Described bus connecting device, described horizontal bus plug connector is set to rectangular slab, and length direction two ends one end is opened elliptical aperture, the other end is opened circular hole.

The slab construction of perforate in the middle of described bus connecting device, described bus retainer are set to, dull and stereotyped arbitrary vertical edge and base be outer flanging A, outer flanging B respectively.

Because adopt aforesaid technical scheme, the beneficial effects of the utility model are:

The bus connecting device that the utility model proposes, be installed on each control cubicle in the busbar correspondence of workshop with segmentation, the segmentation busbar behind the scene on each control cubicle is connected the effect that reaches long busbar through the move left and right of the spacing horizontal bus of bus tie, through the horizontal bus plug connector; Not only reduced requirement, and avoided long busbar repeatedly to dismantle and caused unnecessary loss, product is more standardized, saved manpower and materials, improved operating efficiency the working site size.

Embodiment

Below in conjunction with accompanying drawing the utility model is explained further, be it should be noted that the utility model is not limited to following embodiment, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope.

Among Fig. 1, Fig. 2, Fig. 3,, respectively open two circular holes at horizontal bus 2 two ends with the control cubicle size section of being cut into of horizontal bus 2 according to coupling; With four groups, wherein three groups of power A, B, C horizontal bus 2, one group of horizontal busbar that zero line N horizontal bus 2 overlapping backs form are installed in respectively in relative bus frame 1 groove of control cubicle two, at horizontal bus two ends and bus frame joint, horizontal bus outer end circular hole B7 is corresponding with bus retainer 4 centre bores, connect bus retainer 4 by connector; Inner circular hole A6 is corresponding with horizontal bus plug connector 5 one end circular holes for horizontal bus, connects horizontal bus plug connector 5 by connector.Equally, the horizontal bus that horizontal bus plug connector 5 other end elliptical apertures 8 connect on another control cubicle reaches the effect of long busbar with this.At last vertical busbar 3 correspondences are arranged on the horizontal busbar and get final product.

Among Fig. 5, horizontal bus plug connector 5 is an elliptical aperture 8 with the hole that the horizontal busbar of other control cubicle is connected, the error adjustment when being convenient to the horizontal busbar of each control cubicle and connecting.Among Fig. 4, arbitrary vertical edge of bus retainer 4 flat boards and base be outer flanging A9, outer flanging B10 respectively, and after bus retainer 4 and horizontal bus 2 were fixed, outer flanging A9, outer flanging B10 contacted with bus frame 1 respectively, prevent horizontal bus 2 move left and right.
