Description
Technical field
The utility model relates to capacitor technology field, particularly relates to the electrolytic capacitor being convenient to install.
Background technology
Capacitor, being usually called for short its ability holding electric charge is electric capacity, represents by letter C.Definition 1: capacitor, as the term suggests being ' container of dress electricity ', is a kind of device holding electric charge.English name: capacitor.Capacitor is one of a large amount of electronic component used in electronic equipment, be widely used in circuit every straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.Definition 2: capacitor, any two insulated from each other and all form a capacitor between the conductor (comprising wire) of being separated by very near.
Electric capacity is different from capacitor.Electric capacity is fundamental physical quantity, symbol C, and unit is F (farad).
The special formula of general formula C=Q/U plane-parallel capacitor: electric field strength E=U/d between plate, condenser capacitance determines formula C=ε S/4 π kd.
Along with making rapid progress of electronic information technology, the update speed goes of digital electronic goods is fast, based on the consumer electronics product volume of production and marketing sustainable growth of the products such as panel TV (LCD and PDP), notebook computer, digital camera, capacitor industry has been driven to increase.And having driven the development of associated materials, equipment Industry, China has become global capacitor big producing country.
Electrolytic capacitor of the prior art all comprises body and is arranged on pin outwards exposed on body, pin is for being welded to circuit board by body, in actual applications, capacitor body is welded to after on circuit board by pin, when capacitor body burns or other reasons damages, need to disassemble in the lump together with pin, then reinstall new capacitor, install and bother very much, not only increase maintenance cost, and bringing very large difficulty to maintenance, maintenance efficiency is low.
Utility model content
In view of this, be necessary to provide one to be convenient to maintenance, and be convenient to the electrolytic capacitor of installation.
The utility model realizes like this, be convenient to the electrolytic capacitor installed, comprise body, the side of described body is provided with capacitor pin, also comprise metal joint pin and rotating bolt, described body and capacitor pin are separate, one end of described metal joint pin connects described body, metal joint pin is the electrical connection Metallic rod of body, the other end of described metal joint pin is provided with external screw thread, described rotating bolt is provided with the internal thread matched with described external screw thread, described rotating bolt and metal joint pin are screwed togather mutually by internal thread and external screw thread, one end and the described rotating bolt of described capacitor pin are rotationally connected.
Further, described capacitor pin is shaft-like soft alloy, and length is 5mm ~ 20mm.
Further; contact position between described metal joint pin and body outer surface is provided with spacing rubber protecting jacket; described spacing rubber protecting jacket is fixed on the outer surface of body; and spacing rubber protecting jacket wraps up described metal joint pin, described spacing rubber protecting jacket does not wrap up the external screw thread of described metal joint pin.
The advantage of the electrolytic capacitor that what the utility model provided be convenient to installs is: by by body and the separate setting of capacitor pin, one end of metal joint pin connects body, the other end of metal joint pin is provided with external screw thread, rotating bolt is provided with the internal thread matched with described external screw thread, rotating bolt and metal joint pin are screwed togather mutually by internal thread and external screw thread, one end and the described rotating bolt of capacitor pin are rotationally connected, when mounted, directly capacitor pin is welded on circuit board, after body damages, direct rotary motion bolt, directly body is disassembled, because one end of capacitor pin and described rotating bolt are rotationally connected, capacitor pin is still fixed on circuit boards, again the body got, directly be installed on capacitor pin by rotating bolt, so, do not need dismounting capacitor pin, do not need again to weld yet, and it is convenient and fast connection, save maintenance time and cost.
