Bus ductTechnical field
The present invention relates to a kind of bus duct.
Background technology
The problems such as in the use procedure of existing bus duct, there is the easy ponding of inner chamber, moisture effect is undesirable, intensity has to be strengthened, grafting inconvenience.As in moistureproof, bus, when constructing, easily makes moist and seeps water, causing phase insulation resistance to decline.Bus duct in use, when bus duct inner chamber inner product plays moisture or fog, if successfully the moisture amassed or fog can not be discharged bus duct in time, then easily cause bus duct inner chamber there is ponding and cause the short circuit of circuit, affect the normal use of bus duct and bring potential safety hazard.
In use, the intensity of bus duct needs to strengthen further bus duct, and especially the intensity of cover plate urgently strengthens.In existing cover plate, the bottom panel of cover plate and the junction of side panel are right angle, and under this kind of connected mode, the intensity of cover plate can not meet user demand.When installing cover plate, if do not carry out separation to the L1 phase of bus, L2 phase, L3 phase line and N line to distinguish, then in the use procedure of follow-up bus duct, the problem of as easy as rolling off a log generation bus connection error, need to carry out differentiation to each phase line of bus with this to indicate, ensure in the use procedure after cover plate installation, can correct wiring be carried out, to ensure the normal use of bus duct.
The connection of bus duct and jack box is by filling head and pin realizes.The syndeton of existing dress head and bus, by arranging curved groove on bus, namely after forming groove by the middle part bending of bus, head will be filled insert in curved groove, realize bus and the connection filling head, but under this connected mode, easily cause bus and the loose contact filling head, and be unfavorable for using, and due to the setting of curved groove, the entirety of bus is taken up room excessive.
The problems referred to above should be paid attention to and the problem solved in the design and production process of bus duct.

Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with accompanying drawing.
As Fig. 1, shown in Fig. 2 and Fig. 3, the present embodiment provides a kind of bus duct, comprise bus 11, dress head, cover plate and side plate 9, described cover plate comprises bottom panel 1 and side panel 2, the both sides of described bottom panel 1 are connected to side panel 2, described bottom panel 1 is formed with groove 3 with the junction of described side panel 2, the top of described bottom panel 1 is provided with some waterline grooves 7 for draining and apopore 8, described waterline groove 7 is communicated with described apopore 8, the bottom of described bottom panel 1 is provided with the fin 6 for separating phase line and ground wire, described bottom panel 1 is provided with the bar hole 5 that the some dress heads for connection bus 11 pass through, described side plate 9 is " recessed " type, the inside bottom of described side plate 9 is provided with some radiating grooves 10.The Kong Yanchu of described bar hole 5 is connected with ground connection dress 4, and described ground connection dress 4 is " ten " font.The both sides of described bar hole 5 are respectively equipped with some evenly distributed waterline grooves 7, and described waterline groove 7 is linear, and the two ends of described waterline groove 7 are communicated with apopore 8 respectively, and described waterline groove 7 is U-type groove or V-type groove, and the degree of depth of described waterline groove 7 is 0.3-2mm.Described radiating groove 10 is U-lag or V-shaped groove, and the degree of depth of described radiating groove 10 is 0.6mm-2mm, width is 0.4-3mm, and the shape of described radiating groove 10 is straight line, wavy or bending-like.
As shown in Figure 4, described dress head comprises for the lower contact 13 of connection bus 11 and the top connection 12 for being connected jack box, described top connection 12 connects the end of described lower contact 13, described top connection 12 is cross, described lower contact 13 is T-shaped, described bus 11 is provided with the draw-in groove for holding lower contact 13, and described draw-in groove is T-shaped, and described lower contact 13 is welded in described draw-in groove.The end of described lower contact 13 is provided with deep-slotted chip breaker 14.The inner side of described draw-in groove is provided with the arc head for connecting described deep-slotted chip breaker 14.
A kind of bus duct of the present embodiment, cover plate is by arranging groove 3 at bottom panel 1 and the junction of described side panel 2, with existing cover plate, bottom panel 1 is compared with the right angle connected mode of side panel 2, effectively can improve the intensity of cover plate, thus improve the bulk strength of bus duct, simultaneously the setting of groove 3, add the heat radiation contact area of cover plate and air, ensure the better radiating effect of cover plate further.Groove 3 and side panel 2 are set up in parallel, and ensure the uniformity of the bulk strength of bus duct, the length of groove 3 can be set to the length being less than or equal to side panel 2.The width of described groove 3 is 5-14mm, the degree of depth is 6-10mm, makes the intensity of the cover plate of bus duct more excellent, makes the overall structure of bus duct more adapt to user demand.
This kind of bus duct, the bottom panel 1 of cover plate arranges waterline groove 7 and apopore 8, when running into moisture or fog, the ponding that moisture or fog are formed prolongs waterline groove 7 and flows to apopore 8, derived by apopore 8, prevent the inner cavity water accumulation of bus duct, thus effectively avoid the ponding of bus duct inner chamber to cause short circuit.This kind is for the cover plate of bus duct, be provided with the bar hole 5 that the some dress heads for connection bus 11 pass through, the both sides of bar hole 5 are respectively equipped with some evenly distributed waterline grooves 7, described waterline groove 7 is linear, the two ends of described waterline groove 7 are communicated with apopore 8 respectively, thus the inner cavity water accumulation being convenient to bus duct is derived.
This kind of bus duct, by arranging fin 6 in the bottom of the bottom panel 1 of cover plate, separate phase line and ground wire, ensure after installation cover plate, when carrying out bus 11 grafting, the position of fin 6 can be utilized to separate phase line and ground wire, thus it is accurate to ensure when bus 11 grafting, avoids the use of bus 11 grafting erroneous effects bus duct.
This kind of bus duct, side plate 9 arranges some radiating grooves 10, increase the contact area of side plate 9 and air, thus the increase of area of dissipation can improve heat dispersion, without the need to additionally increasing heat abstractor, can ensure that the heat radiation of bus duct is more abundant, avoid bus duct temperature in use too high, and the weight of bus duct can be alleviated.
This kind of bus duct, by arranging T-shaped draw-in groove on bus 11, after the T-shaped lower contact 13 of dress head and draw-in groove adaptation, welding lower contact 13 and draw-in groove, realize bus 11 and the connection filling head, lower contact 13 and the contact area of bus 11 can be increased, ensure bus 11 and the good contact filling head, and bus 11 and the space shared by coupling part filling head can be saved.The top connection 12 of dress head is decussate texture, thus when filling the connection of head and jack box, can increase the contact area of dress head and jack box, ensures that the contact of whole connection is good further, ensures that bus 11 is connected with the effective of jack box.
The end of lower contact 13 is provided with deep-slotted chip breaker 14, and the inner side of described groove 3 is provided with the arc head for connecting described deep-slotted chip breaker 14, increases lower contact 13 and the contact area of bus 11 further, increases the validity that lower contact 13 is connected with bus 11.The syndeton of this bus 11 and dress head, reasonable in design, by increasing dress head and the contact area of bus 11, jack box, can ensure that filling head is connected with bus 11, the effective of jack box.And lower contact 13 is welded in groove 3, while ensureing that the contact of dress head and bus 11 is fixing, save bus 11 and the space hold of the coupling part of dress head, make the volume of bus 11 less, be more conducive to use.
