Abstract
The utility model discloses an explosion-proof capacitor with a positioning ring, which comprises a shell, wherein an end cover covers the shell, and terminals are arranged on the end cover; a capacitor core body is arranged in the shell, and the neck of the shell is a bellows section; and the positioning ring sleeved outside the shell is arranged at the bottom of the shell. The utility model is simple in structure and is easy to implement and convenient to use, the safety of the capacitor is greatly improved, and the stability of the use performance of the capacitor is also greatly improved.
Description
Technical field
The utility model relates to electron electric power device field, is specially a kind of explosion-proof electric capacity with centring ring.
Background technology
Electric capacity is one of a large amount of electronic components that use in the electronic equipment, is widely used in every aspects such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuits.Electric capacity is to be made of any two insulated from each other and very near conductors of being separated by, and electric capacity is equivalent to open circuit in DC circuit, and in alternating current circuit, circuit passes through between electric capacity by the form of field.Because capacitance applications is very extensive, and the circuit circumstance complication of work, the phenomenon of electric capacity blast also can appear in the electric capacity overload sometimes, if there is not blast resistance construction in the electric capacity, then can cause the injury to the user.Electric capacity needs to use in the place in circuit simultaneously, owing to generally fill maceration extract in the electric capacity, if electric capacity installation attitude is incorrect, maceration extract easily overflows, and influences the performance of electric capacity easily, and influences the circuit that is inserted.
The utility model content
The purpose of this utility model provides a kind of explosion-proof electric capacity with centring ring, can blast to solve electric capacity overload of the prior art, and the problem of the incorrect easy circuit that influences capacitive property and inserted of attitude is installed.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of explosion-proof electric capacity with centring ring, include uncovered housing, described housing open-mouth is covered with end cap, two terminals are installed on the described end cap, the electric capacity core body is arranged in the described housing, described electric capacity core body is electrically connected with two terminals on the end cap by lead, it is characterized in that: the housing neck near the end cap place of covering is shaped to bellows piece, described end cap bottom is stretched in the bellows piece of housing neck, described housing bottom is equipped with and is enclosed within the outer centring ring of housing, described centring ring bottom centre has location hole, and perhaps described centring ring bottom centre is provided with the location stem stem.
The utility model is simple in structure, is easy to realize, and is easy to use, by the housing neck is shaped to bellows piece, the end cap bottom is stretched in the housing neck bellows piece, applies a stress to end cap like this, when electric capacity transships, can not pop easily, improved the fail safe of electric capacity greatly.Position by the centring ring of installing at the housing bottom of electric capacity, centring ring bottom centre has location hole according to the actual installation situation, or the location stem stem is set, and can guarantee that like this electric capacity installation attitude is correct, improved the stability of electric capacity serviceability greatly.
Description of drawings
Fig. 1 is the utility model structural representation, wherein:
Fig. 1 a is the utility model band location hole structural representation, and Fig. 1 b is the utility model band location stem stem structural representation.
Embodiment
As shown in Figure 1.A kind of explosion-proof electric capacity with centring ring, include uncovered housing 1, housing 1 open-mouth is covered with end cap 2, two terminals 3 are installed on the end cap 2, electric capacity core body 4 is arranged in the housing 1, electric capacity core body 4 is electrically connected with two terminals 3 on the end cap 2 by lead 5, housing 1 neck near end cap 2 places of covering is shaped to bellows piece 6, end cap 2 bottoms are stretched in the bellows piece 6 of housing 1 neck, housing 1 bottom is equipped with the centring ring 7 that is enclosed within outside the housing 1, centring ring 7 bottom centre have location hole 8, and perhaps centring ring 7 bottom centre are provided with location stem stem 9.
