Embodiment 1

[0016] figure 1 , image 3 In the illustrated embodiment, a capacitor cover includes a cover 10, and two protruding rectangular strip-shaped push rods 11 are connected to the back of the cover 10 (see figure 2 ), the cover 10 is provided with a through hole 13, and the front side of the cover 10 is connected with the outer peripheral protective body 14 of the through hole 13. The inner diameter of the peripheral shield 14 is larger than the outer diameter of the through hole 13 , forming a peripheral cavity 15 larger than the outer diameter of the through hole 13 , and the height H of the push rod 11 is not lower than the height of the enclosure wall 12 of the cover 10 . The through hole 13 is opened at the center of the cover 10, and the ejector rods 11 are connected to both sides of the through hole 13 respectively. The cover 10 is connected with a cover enclosure wall 12 on the back, and a protruding enclosure strip 121 is connected with the outer periphery of the enclo...

Embodiment 2

[0018] Push rod 11 is or cylinder. Others are the same as in Example 1.

[0019] During production and installation, extend the two protruding ejector rods 11 of the capacitor package cover into the capacitor case. After installation, the back pressure block part 101 of the capacitor package cover is pressed onto the open end face of the capacitor case, and the ejector rods 11 hold the capacitor The inner core is positioned and fixed so that the potting material around it is evenly distributed; to prevent the inner core of the capacitor from moving and floating during potting and casting, the lead wire passes through the middle through hole 13, and then passes through the periphery of the outer peripheral protective body 14 The cavity opening 15 is potted and poured from the through hole 13, which effectively controls the potting volume, is convenient and simple to install and operate, and improves the potting quality.

Abstract

The present invention discloses a capacitor cover. Two projecting top rods are arranged on the back of the cover, and a through hole is arranged on the cover, and a peripheral enclosing body of the through hole on the front face of the cover. An enclosing wall for the cover is arranged on the back of the cover, wherein projecting enclosing bars are arranged on the periphery of the enclosing wall. The top rod is a rectangular strip body or a cylinder body, and the height of the top rod is not less than that of the enclosing wall of the cover. During the manufacturing, two projecting top rods of the encapsulation cover of the capacitor are stretched into the shell of the capacitor, and the internal core member of the capacitor is limited and securely fixed. This prevents the capacitor internal core from moving, floating during the pouring. The lead penetrating through an intermediate opening and the lead is not simply bendable with the peripheral enclosing body. In addition, the pouring quality is improved.

Description

technical field [0001] The invention relates to a capacitor, in particular to a capacitor cover used for packaging capacitors and leading out cables or conductive terminals. Background technique [0002] The existing epoxy resin encapsulated capacitors can be divided into two types, covered and uncovered, in terms of structure. Among them, the covered epoxy resin encapsulated capacitors include cable lead-out type and terminal type, and usually cable lead-out Covered epoxy resin encapsulated capacitors mainly include a shell and a hole that can be positioned. A capacitor core part is built in the shell, and the lower end of the lead-out cable passes through the lead-out cable hole on the cover to realize welding with the capacitor core part. Then, the inner core of the capacitor is packaged and positioned by filling epoxy resin in the shell; while the capped epoxy resin encapsulated capacitor led out from the terminal mainly uses the shell and the cover that can be sealed on...
