Abstract
The utility model relates to an embossed bus. Concave-convex points in an array are arranged on a crimping surface of the bus, so that much fine point-to-point contact of the bus is realized, excessive heating of a contact resistor caused by poor contact of lapping positions of the bus is avoided, and existing potential safety hazards are prevented.
Description
Technical field
The utility model relates to the bus of high-low pressure switchgear assembly, particularly a kind of embossing bus.
Background technology
At present the bus of high-low pressure switchgear assembly mainly through dash, cut, conventional processing such as polishing; because employed equipment or technology accuracy level are limited in the current producer course of processing; the spotty situation of faying surface appears in the bus regular meeting that is produced; in routine processing back the concave arc phenomenon appears on faying surface as some bus; make the bus faying surface not reach the comprehensive engagement effect; in the bus electric energy transmitting; the situation of the excessive heating of contact resistance can occur causing, exist potential safety hazard because of the loose contact of bus overlapping part.
The utility model content
The utility model is in order to overcome above the deficiencies in the prior art, and a kind of rational in infrastructure, embossing bus that contact is effective, safe is provided.
The purpose of this utility model realizes by following technical scheme: a kind of embossing bus, the crimping face of described bus is provided with the sags and crests of arrayization.
Described sags and crests and bus-bar compression joint surface are integral type, and sags and crests is that the frame hydraulic press of 500～1000t and embossing die embossing on bus-bar compression joint surface of plane precision≤5 μ m form by utilization pressure mainly.Bus-bar compression joint surface through embossing not only produces sags and crests, and under pressure, bus-bar compression joint surface reaches smooth effect, in use, the bus contact-making surface is under the securing member active force, and bus overlapping part contact resistance value can reach 2～4 μ Ω, contact resistance value 6～10 μ Ω are low during without embossing than bus faying surface, the resistance contact is little, and laser propagation effect is good, the security performance height.
In order to reach the good result and the overall aesthetics of multiple spot contact, described concave point is the rhombus of 1.5 * 1.5mm, and salient point is
Circle.
The utility model has following advantage with respect to prior art:
A kind of embossing bus of the utility model, the crimping face of bus is provided with the sags and crests of arrayization, make bus realize that many points contact with point the good of form, avoided bus, solved the potential safety hazard that exists because of the overlapping part loose contact causes the situation of the excessive heating of contact resistance.
Description of drawings
Fig. 1 is the structural representation of a kind of embossing bus of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.But execution mode of the present utility model is not limited thereto.
Specific embodiment
As shown in Figure 1, a kind of embossing bus, the crimping face of bus 1 are provided with the concave point 2 and the salient point 3 of arrayization, and in order to reach the good result and the overall aesthetics of multiple spot contact, concave point 2 is the rhombus of 1.5 * 1.5mm, and salient point 3 is
Circle.
Above-mentioned embodiment is a preferred embodiment of the present utility model; can not limit claim of the present utility model; other any change that does not deviate from the technical solution of the utility model and made or other equivalent substitute mode are included within the protection range of the present utility model.
Claims (3)
1. embossing bus, it is characterized in that: the crimping face of described bus is provided with the sags and crests of arrayization.
2. a kind of embossing bus according to claim 1 is characterized in that: described sags and crests and bus-bar compression joint surface are integral type.
