Abstract
The utility model discloses a multi-purpose explosion-proof board, which comprises a circular cover body. The middle part of the front end surface of the circular cover body is provided with a cavity. The cavity is internally provided with a plurality of symmetrical mounting holes. The circular cover body outside the cavity is provided with a plurality of guide slots. The excircle surfaces of the circular cover body between adjacent guide slots are provided with bulges. The rear end surface of the circular cover body is provided with a shallow slot sunken inwards and a plurality of symmetrical convex edges. The convex edges are distributed on both sides of the mounting holes. The multi-purpose explosion-proof board has the advantages of simple structure, convenient installation and use, high production efficiency, reduction of production cost, good sealing effect and improvement of explosion-proof capability and can be widely used in an electrical appliance explosion-proof sealing device.
Description
Technical field
The utility model relates generally to the field of capacitor manufacture of electronic product, relates in particular to a kind of bursting diaphragm of using more.
Background technology
Development along with society, refrigerator, electric furnace, electric iron, hair dryer, some electrical equipment such as air-conditioning have entered huge numbers of families, but in routine work and life because improper use, usually can cause the generation of fire incident, therefore more and more higher to the safety anti-explosive matching requirements of electrical equipment, so capacitor is the important component of each electrical equipment, adopt the integrated explosion-proof notion of initiative at present, use extraordinary microelectric technique, extensive integrated very outstanding with the explosion protection system development of simplifying blast resistance construction, especially refrigerator, not only want cube little, in light weight and similar non-explosion-proof refrigerator is identical, and no external explosion-proof electric apparatus case also requires explosion-proof refrigerator can be placed in the deathtrap simultaneously; Existing noinductive capacitor mainly by mandrel, core body, is enclosed within the upper and lower positioning sleeve at core body two ends, thimble has potting compound between thimble and the core body, is generally vegetable oil, there is the electrode slice of drawing the thimble upper end, and last positioning sleeve upper end is equipped with explosion-proof liner plate, and the thimble neck has two annular grooves, when capacitor is breakdown, produce a large amount of gas, capacitor case expands, and produces mechanical stretching, capacitor one extraction pole opens circuit, thereby reaches explosion-proof effect.Existing noinductive capacitor is owing to must use upper and lower positioning sleeve, and complex structure is installed and used inconvenience, inefficiency, and two hole plugs and the different structure of three hole plugs need can not use unified, cause that production efficiency is low, cost is high, influenced the productivity effect of producing in batches.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of bursting diaphragm of using is provided more, solved general recombiner condenser complex structure, inconvenience is installed, two hole plugs and three hole plugs can not use problems such as production efficiency is low, cost height unified.
The utility model is achieved through the following technical solutions:
A kind of bursting diaphragm of using more, include circular lid, the middle part of described circular lid front end face is provided with cavity, be provided with the installing hole of a plurality of symmetries in the described cavity, it is characterized in that: the circular lid in the described cavity outside is provided with a plurality of guide grooves, and the external periphery of circular lid between the described adjacent guide groove is provided with projection, and described circular lid rear end face is provided with the shallow slot that caves inward, and be provided with the fin of a plurality of symmetries, described fin is distributed in the installing hole both sides.
Described installing hole, fin are respectively six.
The utility model does not need to dispose the last cushion cover in the assembly that has capacitor in use, the installation steps of having saved last cushion cover, and the production efficiency height has reduced labour cost, adopts monolithic construction, and good sealing effect has improved explosion-proof ability; This structure can be used for two hole plugs and three hole plugs unifications simultaneously, and is easy to install.
The utility model has the advantages that:
The utility model is simple in structure, easy to install, production efficiency is high, has reduced production cost, and good sealing effect has improved explosion-proof ability simultaneously, can be widely used in the explosive-proof sealed device of electrical equipment.

Embodiment
A kind of bursting diaphragm of using more, include circular lid 1, the middle part of circular lid 1 front end face is provided with cavity 2, be provided with the installing hole 3 of six symmetries in the cavity 2, the circular lid 1 in described cavity 2 outsides is provided with a plurality of guide grooves 4, and circular lid 1 periphery between the described adjacent guide groove 4 is provided with projection 5, and described circular lid 1 rear end face is provided with the shallow slot that caves inward, and be provided with the fin 6 of a plurality of symmetries, described fin 6 is distributed in installing hole 3 both sides.
Claims (2)
1. use bursting diaphragm one kind more, include circular lid, the middle part of described circular lid front end face is provided with cavity, be provided with the installing hole of a plurality of symmetries in the described cavity, it is characterized in that: the circular lid in the described cavity outside is provided with a plurality of guide grooves, and the external periphery of circular lid between the described adjacent guide groove is provided with projection, and described circular lid rear end face is provided with the shallow slot that caves inward, and be provided with the fin of a plurality of symmetries, described fin is distributed in the installing hole both sides.
2. use bursting diaphragm according to claim 1, it is characterized in that: described installing hole, fin are respectively six more.
