Abstract
The utility model discloses a lower positioning sleeve of a metallized film capacitor, which comprises a plastic shell and a lower positioning sleeve body sleeved to the lower end of the interior of the plastic shell. A bolt is arranged at the lower end of the plastic shell, a nut is screwed on the bolt, a spacer is arranged between the bolt and the nut, epoxy material is filled in the lower positioning sleeve body and covers a capacitor body, the lower positioning sleeve body is in the shape of a round barrel, a plurality of four blisters are arranged on the inner wall of the bottom of the barrel and distributed symmetrically by centering on the inner wall of the bottom of the lower positioning sleeve body, and each blister is 1-2mm high. The lower positioning sleeve has the advantages that the lower positioning sleeve is simple in structure and convenient to manufacture, copper leakage at the bolt below the shell is avoided, polar shell occurrence is reduced, and service life is prolonged.
Description
Technical field:
The utility model relates to capacitor area, specifically is a kind of following positioning sleeve of metallized film capacitor.
Background technology:
Capacitor is a kind of device that holds electric charge, and its science is defined as: the store charge that the electrode that conductor approaching by two and mutually insulated is made is formed and the device of electric energy.For metallized film capacitor, mainly contain by parts such as positioning sleeve, shell, plug, binding post up and down and constitute, be widely used in every directly coupling, bypass, filtering, tuning circuit, power conversion, aspects such as control circuit.The bolt of the utility model below product casing leaks copper, causes product utmost point shell phenomenon to occur in manufacturing process, can avoid electrode one end contact with bolt after increasing by four bubble points, even leakage copper phenomenon utmost point shell can not take place yet bottom the appearance.Because the bubble point height is one millimeter core body, put into enclosure after, core body can directly not contact with outer casing bottom, and is gapped between core body and the following positioning sleeve, can make the epoxy material wrap core body fully like this, increases its endurance quality, prolonged useful life.
The utility model content:
The purpose of this utility model provides a kind of following positioning sleeve of metallized film capacitor, has avoided bolt below the capacitor case to leak copper and cause occurring the phenomenon of utmost point shell in manufacturing process.
The technical solution of the utility model is as follows:
A kind of following positioning sleeve of metallized film capacitor, comprise and mould shell, following positioning sleeve body, described positioning sleeve body down is set in the lower end of moulding shell inside, and the described shell lower end of moulding is provided with bolt, is combined with nut on the bolt, be lined with pad between the screw bolt and nut, following positioning sleeve body interior is filled with the epoxy material, and the epoxy material package is wrapped up in capacitor body, it is characterized in that: described positioning sleeve body down is round barrel shape, bucket end inwall is provided with a plurality of bubble points, and bubble point is a columnar core.
The following positioning sleeve of described metallized film capacitor is characterized in that: described bubble point has four, and the bottom interior wall center of following positioning sleeve body is symmetrically distributed, and the bubble point height is 1-2mm.
The utility model has the advantages that:
The utlity model has simple in structurely, easily manufactured, avoid the bolt below the shell to leak copper, reduced the incidence of utmost point shell phenomenon, prolonged the advantage of long service life.
Description of drawings:
Fig. 1 structural diagrams intention of the present utility model.
Embodiment:
A kind of following positioning sleeve of metallized film capacitor, comprise and mould shell 1, following positioning sleeve body 2, following positioning sleeve body 2 is set in the lower end of moulding shell 1 inside, mould shell 1 lower end and be provided with bolt 3, be combined with nut 4 on the bolt 3, be lined with pad 5 between bolt 3 and the nut 4, following positioning sleeve body 2 inside are filled with epoxy material 6, epoxy material 6 parcel capacitor bodies 7, following positioning sleeve body 2 is round barrel shape, and bucket end inwall is provided with a plurality of bubble points 8, bubble point 8 is a columnar core, bubble point 8 has four, and the bottom interior wall center of following positioning sleeve body 7 is symmetrically distributed, and the bubble point height is 1-2mm.。
