Abstract
The utility model relates to a capacitor shell, which comprises a metal shell body used for placing a capacitor and further comprises a metal shell cap, wherein the metal shell body and the metal shell cap are both cylindrical, the metal shell cap is fixed on the metal shell body, the metal shell cap and the metal shell body are coaxially installed and sealed therebetween, and the metal shell cap and the metal shell body internally form a sealed cavity after being connected, and the metal shell cap is provided with a round hole for a wire to pass through. The capacitor shell provided by the utility model has the advantages that the metal shell cap covers and seals a wiring terminal of the capacitor through arranging the metal shell cap after the capacitor is installed in the metal shell body, and oxygen in the metal shell cap reduces rapidly when a sparking phenomenon occurs, thereby not causing occurrence of an open fire, putting the open fire automatically, effectively avoiding damages for the capacitor and the occurrence of a fire disaster, and being safe and reliable.
Description
Technical field
The utility model relates to capacitor area, relates in particular to a kind of capacitor case.
Background technology
Electric capacity is called in the common letter of capacitor, by letter C, represents.Definition 1: capacitor, as its name suggests, be ' filling electric container ', be a kind of device that holds electric charge, electric capacity is one of a large amount of electronic components that use in electronic equipment, be widely used in circuit every aspects such as straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion and controls.Definition 2: capacitor, any two insulated from each other and be separated by and between very near conductor (comprising wire), all form a capacitor.
In prior art; capacitor is generally all arranged in fixing capacitor case; but capacitor case is only parcel electric capacity itself; the copper lug that connects electric capacity is placed in housing exterior, after long-time use, has certain probability to produce spark between copper lug; cause capacitor to burn; shell can not well be protected capacitor, causes loss, holds fire hazardous and occurs.
Utility model content
In view of this, be necessary to provide a kind of safety, avoid burning because spark phenomenon causes capacitor, the capacitor case of avoiding fire to occur.
The utility model is to realize like this, a kind of capacitor case, comprise for installing the metal shell of capacitor, also comprise metal-back cap, described metal shell and metal-back cap are all tubular, and described metal-back cap is fixed on described metal shell, and coaxial installation, between described metal-back cap and metal shell, seal, and after metal-back cap is connected with metal shell, the inner cavity that forms a sealing.
Further, described metal-back cap is provided with the circular hole passing through for electric wire.
The advantage of a kind of capacitor case that the utility model provides is: by metal-back cap is set, after capacitor is installed in metal shell, by metal-back cap, the terminals of capacitor are covered and sealed, when there is spark phenomenon, oxygen in metal-back cap reduces rapidly, can not cause the appearance of naked light, automatic distinguishing naked light, effectively avoided the damage of capacitor and the generation of fire, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of capacitor case of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is the structural representation of a kind of capacitor case of the utility model.
Described a kind of capacitor case, comprise for installing the metal shell 10 of capacitor, also comprise metal-back cap 20, described metal shell 10 is all tubular with metal-back cap 20, described metal-back cap 20 is fixed on described metal shell 10, and coaxial installation, sealing between described metal-back cap 20 and metal shell 10, and after metal-back cap 20 is connected with metal shell 10, the inner cavity that forms a sealing.
Described metal-back cap 20 is provided with the circular hole 21 passing through for electric wire, after installing electric wire, will between electric wire and circular hole 21, seal, and guarantees that whole capacitor case inside is in sealing state.
By metal-back cap 20 is set, capacitor is installed to metal shell 10 interior after, by metal-back cap 20, the terminals of capacitor are covered and sealed, when there is spark phenomenon, oxygen in metal-back cap 20 reduces rapidly, can not cause the appearance of naked light, automatic distinguishing naked light, effectively avoided the damage of capacitor and the generation of fire, safe and reliable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
Claims (2)
1. a capacitor case, comprise the metal shell (10) for installing capacitor, it is characterized in that, also comprise metal-back cap (20), described metal shell (10) is all tubular with metal-back cap (20), and described metal-back cap (20) is fixed on described metal shell (10), and coaxial installation, sealing between described metal-back cap (20) and metal shell (10), and after metal-back cap (20) is connected with metal shell (10), the cavity that inner formation one seals.
