The start capacitor comprises a casing and a cover board, wherein the casing and the cover board are closed to form a chamber, the chamber is interlay provided with a core packet, a positioning sleeve used for fixing the core packet in the chamber is arranged between the core packet and the casing, the cover board is fixed with a pair of metal plug-ins, and the plug-ins and the core packet are electrically connected through leading wires. The start capacitor has advantages of small capacitance loss and stable performance.
Description
Technical field
The utility model belongs to technical field of electronic devices, has related to a kind of start-up capacitance.
Background technology
Capacitor is one of a large amount of electronic components that use in electronic equipment, is applicable to every aspects such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuits.And start-up capacitance is the one in capacitor, be mainly used in using and helping electric motor starting with AC single phase electric drilling match.In when work, this start-up capacitance exists that loss is large, the shortcoming of unstable properties.
Summary of the invention
The problems referred to above that the utility model exists for prior art, have proposed that a kind of loss is little, the start-up capacitance of stable performance.
The utility model is realized by following technical proposal: a kind of start-up capacitance, comprise housing and cover plate, described housing and cover plate closing form a cavity, it is characterized in that, in described cavity, be provided with core bag, between described core bag and described housing, be provided with the positioning sleeve for core bag being fixed on to cavity, on described cover plate, be fixed with pair of metal plug-in unit, between described plug-in unit and described core bag, by lead-in wire, be electrically connected.
In above-mentioned a kind of start-up capacitance, described housing outer wall is socketed with heat-shrinkable T bush, and the top of described heat-shrinkable T bush is fixing on the cover board.
In above-mentioned a kind of start-up capacitance, described plug-in unit comprises setting inserted sheet on the cover board and the leader being electrically connected through cover plate and with lead-in wire, and described inserted sheet and described leader are welded and fixed.
In above-mentioned a kind of start-up capacitance, the height of described positioning sleeve is 1/4～1/2 of housing height.
Compared with prior art, this start-up capacitance has advantages of that loss is little, stable performance when work.
