Abstract
The utility model provides a kind of guide pin of high-voltage capacitor, and it includes guide pin stitch, and stitch one end is provided with joint pin, and the external diameter of joint pin is greater than stitch external diameter, and the connecting portion of joint pin and stitch adopts tapering transition; The joint pin other end is provided with draw-in groove, and brace one end is nested in draw-in groove and by being welded and fixed, the nail joint of the brace other end is on capacitor aluminium foil, and the contact-making surface of described brace and capacitor aluminium foil is curved, and its radian matches with the coil diameter of capacitor aluminium foil; Brace two ends adopt arc rounding off.The utility model is after employing such scheme, and brace plate face adopts cambered design, makes two of winding rear connecting piece contact-making surfaces be close on aluminium foil or electrolytic paper, gap can not be there is again in its contact-making surface, after winding, the superimposed degree of electric capacity is better, and winding is tightr, greatly can reduce capacity loss.
Description
Technical field
The utility model relates to a kind of capacitance technology field, refers in particular to a kind of guide pin of high-voltage capacitor.
Background technology
At present, as the significant components of the module such as inversion, transformation in new energy system, aluminium electrolytic capacitor is expected to open up the application market made new advances in the new energy such as solar energy, wind energy system.In in the past more than 20 year, wind power generation constantly surmounts the development speed of its expection, remains the status of the fastest energy of world development always.Global wind-powered electricity generation adds up the average growth rate per annum of installed capacity close to 30% nearly ten years.Along with " energy-saving and emission-reduction " being day by day rooted in the hearts of the people of thought, converter technique, obtain at all fields of national economy and apply more widely, with wind power generation, photovoltaic generation is the green energy resource field of representative, and urban rail transit construction like a raging fire, all proposes huge demand to aluminium electrolytic capacitor, therefore to capacitor high voltage withstanding, adverse circumstances.Long-life, the requirement of resistance to ripple aspect is more harsh, but also starts the new market of capacitor and development.Existing capacitance guide needle contact-making surface is all adopt slab construction, and this structure is when winding capacitance, and because guide pin is tabular, and electric capacity winding is cylindric, causes easily being formed between guide pin and aluminium foil gap, greatly affects the result of use of electric capacity.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of easy to operate, practical, the guide pin that greatly can reduce capacity loss of high-voltage capacitor.
For achieving the above object, technical scheme provided by the utility model is: a kind of guide pin of high-voltage capacitor, and it includes guide pin stitch, and stitch one end is provided with joint pin, the external diameter of joint pin is greater than stitch external diameter, and the connecting portion of joint pin and stitch adopts tapering transition; The joint pin other end is provided with draw-in groove, and brace one end is nested in draw-in groove and by being welded and fixed, the nail joint of the brace other end is on capacitor aluminium foil, and the contact-making surface of described brace and capacitor aluminium foil is curved, and its radian matches with the coil diameter of capacitor aluminium foil; Brace two ends adopt arc rounding off.
Described draw-in groove inner chamber is curved, and its radian matches with brace plate face radian.
Described brace plate face is provided with several square nail joint holes, and is connected with capacitor aluminium foil by square nail joint hole.
The utility model is after employing such scheme, by joint pin connection reinforcement between stitch and brace, can effectively prevent stitch from rupturing, brace plate face adopts cambered design, making two of winding rear connecting piece contact-making surfaces be close on aluminium foil or electrolytic paper, can not there is gap in its contact-making surface again, and after winding, the superimposed degree of electric capacity is better, winding is tightr, greatly can reduce capacity loss.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of brace.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1 and accompanying drawing 2, the guide pin of a kind of high-voltage capacitor described in the present embodiment includes guide pin stitch 1, stitch 1 one end is provided with joint pin 2, the external diameter of joint pin 2 is greater than stitch 1 external diameter, and joint pin 2 adopts tapering transition with the connecting portion of stitch 1; Joint pin 2 other end is provided with draw-in groove 3, described draw-in groove 3 inner chamber is curved, its radian matches with brace 4 plate face radian, brace 4 one end to be nested in draw-in groove 3 and by being welded and fixed, the nail joint of brace 4 other end is on capacitor aluminium foil, described brace 4 is curved with the contact-making surface of capacitor aluminium foil, and its radian matches with the coil diameter of capacitor aluminium foil; Brace 4 two ends adopt arc rounding off, and described brace 4 plate face is provided with several square nail joint holes, and is connected with capacitor aluminium foil by square nail joint hole.This device is after employing such scheme, by joint pin connection reinforcement between stitch and brace, can effectively prevent stitch from rupturing, brace plate face adopts cambered design, making two of winding rear connecting piece contact-making surfaces be close on aluminium foil or electrolytic paper, can not there is gap in its contact-making surface again, and after winding, the superimposed degree of electric capacity is better, winding is tightr, greatly can reduce capacity loss.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection range of the present utility model.
