Abstract
The invention discloses a capacitor with a heat shield. The capacitor with the heat shield comprises: a capacitor shell; a core, which is arranged in the capacitor shell; terminals and a grounding bolt, which are arranged on two ends of the capacitor shell. A heat insulation rib is arranged on a bottom transverse plane of the capacitor shell. The heat shield covers an outer end of the bottom transverse plane. A slot which matches with the heat insulation rib and a through hole which is used to be passed through by the grounding bolt are arranged on the heat shield. An external surface of the heat shield is a plane. By using the capacitor with the heat shield, a heat insulation problem of the capacitor can be solved and stability of connection between the capacitor and the fixed plane can not be influenced.
Description
Technical field
The present invention relates to electrician's technical field of tools, specifically, relate to a kind of capacitor that has heat shield.
Background technology
Electric capacity is called in the common letter of capacitor, as its name suggests, is " container of dress electricity ", is a kind of device that holds electric charge.Electric capacity is one of a large amount of electronic components that use in the electronic equipment, is widely used in separated straight-through friendship the in the circuit, coupling, bypass, filtering, resonant tank, power conversion, aspects such as control.In the prior art, the structure of capacitor generally includes capacitor case, is positioned at the inner core body of capacitor case; Be positioned at the binding post and the earth stud at capacitor case two ends, binding post penetrates the electrode that connects core body from the end face of shell, and the surface of shell is generally very smooth; This capacitor is with inductance type or the supporting use of ballast the time, and the outer casing bottom end face at its earth stud place often is fixed on the same metal plate with ballast, along with the prolongation of service time; The heat that ballast produces in the course of the work causes the also heating gradually of outer casing bottom end face of capacitor through transmission of heat by contact, and capacitor is easy to take place the heat ageing phenomenon under long-time high-temperature condition; Thereby had a strong impact on the use useful life of capacitor; Therefore, be necessary to design a kind of new additional structure, solve the heat-insulating problem of capacitor.
Therefore, based on the problem that exists in the prior art, be necessary to design a kind of capacitor that has heat shield, promptly can solve the heat-insulating problem of capacitor, simultaneously, the setting of additional structure can not influence capacitor and fixed pan connection stability.
Summary of the invention
This purpose is to provide a kind of capacitor that has heat shield, is intended to solve the heat-insulating problem of capacitor, simultaneously, can not influence capacitor and fixed pan connection stability.
In order to realize the object of the invention, the technical scheme that the present invention adopts is:
A kind of capacitor that has heat shield; Comprise capacitor case, be positioned at the inner core body of capacitor case, be positioned at the binding post and the earth stud at capacitor case two ends; The bottom end face of said capacitor case is provided with heat insulation rib; Said heat shield is sleeved on the outer end of bottom end face, and said heat shield is provided with slot that is complementary with heat insulation rib and the through hole that supplies earth stud to pass, and the outer surface of said heat shield is the plane.
The side view of said heat shield and the outer surface of capacitor case are complementary.
Said heat shield is one-body molded by heat insulation felt.
Beneficial effect of the present invention is:
1. can solve the heat-insulating problem of capacitor;
2. can not influence capacitor and fixed pan connection stability.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the sketch map after the assembling of heat shield and capacitor among Fig. 1.
Among the figure: 1, capacitor case; 2, binding post; 3, earth stud; 4, heat insulation rib; 5, heat shield; 6, slot; 7, through hole.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3.
A kind of capacitor that has heat shield; Comprise capacitor case 1, be positioned at the core body of capacitor case 1 inside, be positioned at the binding post 2 and earth stud 3 at capacitor case 1 two ends; The bottom end face of said capacitor case 1 is provided with heat insulation rib 4; Said heat shield 5 is sleeved on the outer end of bottom end face, and said heat shield 5 is provided with slot 6 that is complementary with heat insulation rib 4 and the through hole 7 that supplies earth stud 3 to pass, and the outer surface of said heat shield 5 is the plane.
The outer surface of the side view of said heat shield 5 and capacitor case 1 is complementary.Heat shield 5 shape with capacitor case basically is consistent, for cylindric.
Said heat shield 5 is one-body molded by heat insulation felt.
Cooperate with slot 6 through heat insulation rib, the bottom end face and the joint face of capacitor case 1 separated, and adopt heat-barrier material such as heat insulation felt, dual heat insulation, can prevent effectively that capacitor is heated.
The present invention can solve the heat-insulating problem of capacitor; And can not influence capacitor and fixed pan connection stability.
What embodiments of the invention were announced is preferred embodiment, but is not limited thereto those of ordinary skill in the art; Very easily, understand spirit of the present invention, and make different amplifications and variation according to the foregoing description; But only otherwise break away from spirit of the present invention, all in protection scope of the present invention.
