Abstract
The utility model discloses a copper bar connecting structure capable of reducing power unit assembling accumulated tolerance; the copper bar connecting structure comprises a copper bar; the copper bar comprises an L-shaped right angle folding portion; two end portions of the L-shaped right angle folding portion are respectively connected with a parallel connecting portion perpendicular to the L-shaped right angle folding portion; the parallel connecting portions are respectively provided with a plurality of capacitor connecting fixing employed waist-type holes. Waist-type holes are arranged on portions, connected with capacitors, of the novel copper bar connecting structure in a horizontal direction, thereby effectively compensating size offset caused by capacitor mounting errors; in a vertical direction, the copper bar is folded in the right angle form, negative tolerance requirements are realized, and connection between the IGBT and the copper bar is effectively ensured; the copper bar connecting structure is convenient in assembling, can effectively reduce accumulated tolerance caused by fixation of the capacitors and the IGBT, solves copper bar mounting difficulty, improves usage performance of elements, and prolongs service life.
Description
Technical field
The utility model relates to high voltage converter technical field, relates in particular to a kind of copper bar draw bail that reduces power cell assembly accumulation tolerance.
Background technology
During assembling, running into the overproof thing of accumulation tolerance, is recurrent, and Hen is general for this problem.Sometimes designer, in design, ignores the physical device situation of enterprise and personnel's process technology ability, pursues simply the high accuracy of processing, and the high accuracy coordinating, and when result is assembling, part part will be repaiied, and instead arrives precision poorer.In general, from design, will expect and there will be this problem, thus a size governing loop of design.If this link does not design, will give assembling and repair and bring huge trouble.
Utility model content
The utility model object is exactly the defect in order to make up prior art, and a kind of copper bar draw bail that reduces power cell assembly accumulation tolerance is provided.
The utility model is achieved through the following technical solutions:
A kind of copper bar draw bail that reduces power cell assembly accumulation tolerance, include copper bar, described copper bar includes L-type right-angle bending part, two ends in L-type right-angle bending part are connected with respectively the parallel coupling part perpendicular with L-type right-angle bending part, are respectively equipped with multiple electric capacity employing waist-shaped hole that is connected and fixed on described parallel coupling part.
Described L-type right-angle bending part meets the requirement of short transverse negative common difference.
During assembling, when the power cell assembling of L-type topology layout, due to the installation fixed error of IGBT and electrochemical capacitor, caused electrochemical capacitor and IGBT connecting copper bar that difficulty is installed, install and will damage components and parts by force, this copper bar draw bail electrochemical capacitor and IGBT connecting copper bar mounting hole effective compensation by electric capacity, the error in the horizontal direction producing is installed, in the vertical direction, negative common difference can effectively guarantee and the connecting of IGBT in conjunction with right-angle bending mode.
The utility model has the advantages that: the utility model copper bar is connected in the position that horizontal direction connects with electric capacity and has taked mounting hole to fix, effectively compensated the size offset causing because of electric capacity alignment error, in the vertical direction, adopt copper bar folding for right angle form, negative common difference requirement, in the time of effectively, guaranteed contacting of IGBT and copper bar, easy to assembly, effectively reduced the fixing cumulative limit producing because of electric capacity and IGBT, solved the problem of copper installation difficulty, the serviceability that has promoted components and parts, increases the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of copper bar draw bail that reduces power cell assembly accumulation tolerance, include copper bar 1, described copper bar 1 includes L-type right-angle bending part 2, two ends in L-type right-angle bending part 2 are connected with respectively the parallel coupling part 3 perpendicular with L-type right-angle bending part 2, on described parallel coupling part 3, be respectively equipped with multiple electric capacity be connected and fixed adopt waist-shaped hole 4.
Described L-type right-angle bending part 2 meets the requirement of short transverse negative common difference.
Claims (2)
1. one kind reduces the copper bar draw bail of power cell assembly accumulation tolerance, it is characterized in that: include copper bar, described copper bar includes L-type right-angle bending part, two ends in L-type right-angle bending part are connected with respectively the parallel coupling part perpendicular with L-type right-angle bending part, are respectively equipped with multiple electric capacity employing waist-shaped hole that is connected and fixed on described parallel coupling part.
2. the copper bar draw bail that reduces power cell assembly accumulation tolerance according to claim 1, is characterized in that: described L-type right-angle bending part meets the requirement of short transverse negative common difference.
