Abstract
The utility model discloses an improved connecting terminal for a large-sized aluminum electrolytic capacitor, which comprises a columnar conductor. Threads are formed on the inner wall and the outer wall of the upper part of the columnar conductor, a plurality of ring-shaped wings surrounding the circumferential wall of the columnar conductor are arranged at the middle part of the columnar conductor, the lower part of the columnar conductor extends out of the connecting terminal, the middle part of the columnar conductor is wrapped with resin, and an axle hole of the columnar conductor is provided with threads. The improved connecting terminal for the large-sized aluminum electrolytic capacitor has the advantages of better connection performance, larger connection area, lower metallic resistance, low liability of heating and rusting, and good sealing performance.
Description
Technical field
The utility model relates to a kind of terminal of aluminium electrolytic capacitor, specifically belongs to the splicing ear of Improvement type large-scale aluminum electrolysis capacitor.
Background technology
When large-scale aluminum electrolysis capacitor is used in the line at present, terminal as the conventional aluminium electrolytic capacitor is exposed in the damp-heat air outward, during use when high frequency or big current work, the oxidative phenomena that generates heat can appear in the aluminium matter terminal of aluminium electrolytic capacitor, make the line contact electric property of aluminium electrolytic capacitor descend, it is big that contact resistance slowly becomes, the terminal of last aluminium electrolytic capacitor even get rusty, get rusty terminal and wire rod indirect contact, electrical property is had a greatly reduced quality, also have simultaneously and run into the screw that connection cable uses and to twist, maintaining work such as can not be convenient for changing; In addition, the fine aluminium terminal surfaces profile of aluminium electrolytic capacitor is the simple geometric shape, because it is simple in structure, do not adopt particular design, cause seepage electrolyte between plastics and the fine aluminium terminal easily, directly influence the serviceability and the life-span of aluminium electrolytic capacitor, caused the inefficacy of aluminium electrolytic capacitor.
The utility model content
The purpose of this utility model is to address the aforementioned drawbacks, and a kind of switching performance is better, the connection area is bigger and provide, and metallic resistance is littler, and difficult heating is got rusty, the splicing ear of the Improvement type large-scale aluminum electrolysis capacitor of good airproof performance.
For achieving the above object:
The splicing ear of Improvement type large-scale aluminum electrolysis capacitor, comprise cylindrical conductor, the top inside and outside wall of cylindrical conductor has screw thread, the middle part is provided with several ring alar parts that are around in the cylindrical conductor periphery wall, the bottom is stretched out and is connected the end, the middle part of cylindrical conductor is enclosed with resin, and the axis hole of cylindrical conductor is provided with screw thread.
Described ring alar part has certain distance with the ring alar part, constitutes groove between ring alar part and the ring alar part.
Described ring alar part is the ladder setting from bottom to top with the ring alar part.
Described cylindrical conductor terminal integral body is that 99.99% purity aluminium matter is made.
The beneficial effects of the utility model:
The terminal of alminium electrolytic condenser of the present utility model, cylindrical conductor are that 99.99% purity aluminium matter is made, and use the easy electrochemistry of terminal surfaces of rafifinal matter to generate dielectric film, reduce leakage current.The top inside and outside wall of cylindrical conductor has screw thread, and two-way wiring is connected (Low ESR connection) with terminal, and solid and reliable, the charging and discharging currents processing speed is faster.The middle part is provided with several ring alar parts that are around in the cylindrical conductor periphery wall, naturally form annular groove in the middle of the ring alar part, resin is under the certain pressure effect, in the injection ring connected in star, and bag is tied up terminal ring alar part fully, the design of ring alar part, increased the machinery kiss and the area of resin and terminal, thereby increased the constant intensity of terminal in resin, be difficult for loosening, prolonged the path of the interior molecule of aluminum hull simultaneously to the outside diffusion motion of aluminum hull, rush down the defence line effect of leaking so play lengthening, the sealing raising is a lot, and the bottom is stretched out and connected the end, lead the paper tinsel exit for riveted joint, can weld or rivet.
