Description
Technical Field
The utility model relates to a condenser technical field specifically indicates a photovoltaic direct current filtering capacitor of shell area constant head tank.
Background
The current market generally designs the structure as follows: there is not location needle groove on the shell, uses traditional copper needle correction equipment to carry out location correction, because of the position correction in-process, the condition of quality hidden danger appears, and the concrete expression is following two points:
1. scratching of the copper needles occurred.
2. In the correction process of the device, the force is too large, so that the deformation of the copper needle is caused,
3. when the equipment is worn, the consistency of the installation distance of the product is poor.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is, to the above-mentioned problem, provide a casing area constant head tank's capacitor for photovoltaic direct current filtering of high, the production efficiency of easy operation, product qualification rate.
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a photovoltaic direct current of shell area constant head tank capacitor for filtering, includes engineering plastics area pilot pin groove square casing, blue solid epoxy and thickening cladding layer tinned copper needle, the inside of engineering plastics area pilot pin groove square casing is equipped with the electric capacity core, the top of engineering plastics area pilot pin groove square casing is equipped with thickening cladding layer tinned copper needle, thickening cladding layer tinned copper needle passes through high-frequency heavy current butt-weld mode with the electric capacity core and fixes together, be equipped with blue solid epoxy between electric capacity core and the engineering plastics area pilot pin groove square casing.
As an improvement, the capacitor core is connected with the thickened plated tin-plated copper pin through welding.
As an improvement, blue solid epoxy resin 3 is filled between the capacitor core and the engineering plastic square shell with the positioning needle groove, and the capacitor core is wrapped by the blue solid epoxy resin.
Compared with the prior art, the utility model the advantage lie in: the capacitor has the performance of fixing the installation distance of the copper pins, and the problem that the installation distance of the copper pins does not meet the requirements of customers in the assembling or carrying process of workers, so that the size requirement of a product is influenced is avoided; the capacitor is safer and more reliable, so that the performance is more stable and the service life is longer; the production operation of the product is simple, the qualification rate of the product is high, and the production efficiency is high.
