Abstract

The invention belongs to low voltage electric equipment, it relates to the slot of illuminating line. said slot body comprises a motherboard and two side boards which are vertical to the motherboard, the upper edge of the side board is bent to inner and lower to form a plughed groove which uncorks adown, at the same time orientation protuberance is on surface of the side board; The main body of said cover board is flat structure, the two edges are turned up to form cocked hems, two hems are separately inserted into theplughed groove of the upper of the side board, at the same time the bottom of the cover board is limited by the orientation protuberance. The structure of the invention is simple, the weight is light, it is corrosion resistant, effect of the radiating is well, and the manufacture and installation are convenient.

Description

Illuminating bus slot

Technical field

The invention belongs to the low pressure equipment for power transmission and distribution, relate to a kind of illuminating line wire casing that is used for.

Background technology

Be used for the little illuminated bus duct of low pressure power transmission and distribution at present, its housing adopts steel design mostly, and the housing each several part generally adopts welding or connects by securing member.The bus duct of this structure exists product weight weight, easy-to-rust, radiating effect is poor, installation is inconvenient, make defectives such as efficient is low.

Summary of the invention

Technical problem to be solved by this invention is, a kind of simple in structure, in light weight, corrosion-resistant, good heat dissipation effect, manufacturing and illuminating bus slot easy for installation are provided.

Illuminating bus slot of the present invention is made up of cell body and cover plate, described cell body is made up of with two side plates vertical with base plate a base plate, the upper end-face edge of side plate inwardly and is downwards bent, and forms the groove that colludes that Open Side Down, also is provided with locator protrusions at the side plate inner surface near the upper end-face edge place simultaneously; Described cover plate main body is a slab construction, and the cover plate both sides of the edge are turned up and formed the flanging of holding up, and two flangings are inserted in colluding in the groove of above-mentioned side plate upper end respectively, and the bottom of cover plate is spacing by the locator protrusions on the above-mentioned side plate simultaneously.Described cell body and cover plate are made by aluminium alloy extrusions.

The present invention is owing to adopt the cell body of aluminum alloy materials and the housing that cover plate is formed bus duct, alleviated on the one hand bus duct weight, improved corrosion resistance and heat-sinking capability; Cell body and cover plate can be made by the aluminium alloy type material of particular cross section on the other hand, can enhance productivity; In addition, cell body and cover plate cooperate with the grafting of flanging and are connected by colluding groove, can will collude groove and the tight interlock of flanging by interlock equipment after grafting is finished, and do not need securing member or are welded to connect, and have simplified manufacturing process.

Description of drawings

Fig. 1 is an end face structure schematic diagram of the present invention;

Fig. 2 is the structural representation of looking up of Fig. 1.

Embodiment

As shown in Figure 1, the cell body 1 and the cover plate 2 of bus duct of the present invention all adopt the aluminium alloy extrusions manufacturing, cell body is made up of a base plate 11 and two side plates 12, groove 121 is colluded in the setting of side plate upper end-face edge, there is the flanging of holding up 21 cover plate 2 both sides of the edge, the flanging 21 of cover plate cooperates with groove 121 grafting of colluding of side plate upper end-face edge setting, and the bottom of cover plate is spacing by the locator protrusions 122 of side plate inboard.

The actual manufacturing process of the bus duct of this structure is, insulated leg 3 and each phase conductor 4 with routine is installed in the inner chamber of cell body 1 earlier, to cooperate by cell body and the cover plate grafting that illustrated section shape section bar is made again, the flanging of cover plate and cell body collude groove peg graft put in place after, push the both sides of colluding groove 121 by interlock equipment, make collude groove dual-side closely interlock be clamped on the flanging 21 of cover plate, thereby finish being connected of cover plate and cell body.

As shown in Figure 2, on the base plate 11 of cell body, also have the spliced eye 111 that is used for installing branch's plug assembly.

Claims (3)

1, a kind of illuminating bus slot, form by cell body (1) and cover plate (2), it is characterized in that: described cell body (1) is made up of with two side plates vertical with base plate (12) a base plate (11), the upper end-face edge of side plate inwardly and is downwards bent, what form that Open Side Down colludes groove (121), also is provided with locator protrusions (122) at the side plate inner surface near the upper end-face edge place simultaneously; Described cover plate (2) main body is a slab construction, and the cover plate both sides of the edge are turned up and formed the flanging of holding up (21), and two flangings are inserted in colluding in the groove (121) of above-mentioned side plate upper end respectively, and the bottom of cover plate is spacing by the locator protrusions (122) on the above-mentioned side plate simultaneously.
