CN203826209U - Capacitor housing - Google Patents

Abstract

The utility model discloses a capacitor housing comprising a cylindrical shell. The capacitor housing is characterized in that the center of the external side of the bottom part of the shell is provided with a cylinder which is provided with an axial internal screw hole. The internal screw hole is coaxial with the cylinder. The edge of the external side of the bottom part of the shell is provided with a clamping position. The clamping position and the cylinder with the screw hole are arranged so that fixing of a capacitor is more solid and reliable, and a problem that the capacitor with higher weight is not solidly fixed is solved.

Description

A kind of capacitance shell

Technical field

The utility model relates to a kind of capacitance shell.

Background technology

Existing capacitance shell major part is fixing by the mode of tin welding, this fixed form is applicable to the installation of the electric capacity that weight is lighter and fixes, fixing firm not for the heavier electric capacity of weight, if and electric capacity can produce great vibrations for time on the mobile device such as locomotive, simply take soldering mode cannot reach requirement.

Utility model content

For solving the problems of the technologies described above, we have proposed a kind of capacitance shell, have solved the heavier fixing not firmly problem of electric capacity of weight.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of capacitance shell, comprises barrel-type casing, and the center in described housing bottom outside is provided with cylinder, is provided with axial inner bolt hole in described cylinder, and described inner bolt hole is coaxial with described cylinder, and the edge in described housing bottom outside is provided with screens.

Preferably, described screens is provided with two, and described two screens are about cylinder symmetry, and is parallel to each other.

By technique scheme, a kind of capacitance shell the utility model proposes, by screens and the cylinder with screw are set, makes the fixing more solid and reliable of electric capacity, has solved the heavier fixing not firmly problem of electric capacity of weight.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Below in conjunction with embodiment and embodiment, the utility model is described in further detail.

Embodiment

As Figure 1-3, a kind of capacitance shell, comprises barrel-type casing 1, the center of housing 1 bottom outside is provided with cylinder 2, in cylinder 2, be provided with axial inner bolt hole 3, inner bolt hole 3 is coaxial with cylinder 2, and the edge of housing 1 bottom outside is provided with screens 4, screens 4 is provided with two, two screens 4 are about cylinder 2 symmetries, and are parallel to each other, and screens 4 is for limiting the movement of housing 1, in inner bolt hole 3, be provided with screw, by screw, housing 1 lock onto on installation portion.

By technique scheme, a kind of capacitance shell the utility model proposes, by screens and the cylinder with screw are set, makes the fixing more solid and reliable of electric capacity, has solved the heavier fixing not firmly problem of electric capacity of weight.

Above-described is only the preferred implementation of a kind of capacitance shell of the utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.

Claims (2)
