Abstract
A capacitor belonging to the field of capacitor comprises a casing, a capacitor core arranged in the casing, a cover plate covered on the casing and wiring terminals arranged on the cover plate, and is characterized in that the bottom part of the casing is provided with a groove, the groove is provided with a convex point, the groove extends from the edge to the central position of the bottom part of the casing, the groove is in an inverted V shape, and the top part of the inverted V-shaped groove is an arc transition structure. The capacitor has the advantages of simple structure and reasonable design, the groove is arranged at the bottom part of the casing, the convex point is arranged in the groove, the contact area of the capacitor with the circuit board can be reduced, the ventilation and heat dissipation are facilitated, and the phenomena of unfirm contact caused by point contact and looseness during vibration can be avoided.
Description
Technical field
The utility model relates to a kind of electronic component, is specifically related to a kind of capacitor.
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 electronic equipment, is widely used in handing over every straight-through in circuit, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.Capacitor generally by housing, be arranged on core body in housing, cover the cover plate on housing and the lead wire that arranges on the cover board forms, cylindrical shape capacitor of the prior art, housing bottom is smooth, be arranged on circuit board because contact area is large, on circuit board during other electric component excess Temperature, the radiating effect of capacitor is bad, therefore can directly affect the useful life of capacitor.In order to solve the poor problem of capacitor radiating effect, also there is the people at housing bottom, a plurality of projections to be set, when mounted, between capacitor and circuit board, the space is arranged, therefore be conducive to ventilation and heat; But because the bossing magnitude setting is too much, capacitor and circuit board contact area are little, are all by the point-like contact, therefore are prone to installation insecure, caducous phenomenon.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of reasonable in design, good heat dissipation effect, and adeciduate capacitor is installed firmly.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of capacitor, comprise housing, be arranged on the interior capacitor body of housing, cover cover plate and setting binding post on the cover board on housing, it is characterized in that: described housing bottom is provided with groove, is provided with salient point in groove, and described groove extends to the center by the edge of housing bottom.
Described salient point is arranged on the central point of housing bottom.
Described groove be "
" type,
The top of type groove is the arc transition structure.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, at housing bottom, groove is set, salient point is set in groove, both can reduce the contact area with circuit board, be beneficial to ventilation and heat, point-like contact can not appear again and cause contacting insecure, the phenomenon that occurs getting loose when vibration.
Description of drawings
Fig. 1 is a kind of anti-deformation capacitor arrangement of the utility model schematic diagram.
Wherein: the 1-housing; The 2-capacitor body; The 3-cover plate; The 4-binding post; The 5-groove; The 6-salient point.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of capacitor, comprise housing 1, be arranged on capacitor body 2 in housing 1, cover at the cover plate 3 on housing 1 and be arranged on binding post 4 on cover plate 3, housing 1 bottom is provided with groove 5, be provided with salient point 6 in groove 5, groove 5 extends to the center by the edge of housing 1 bottom, and salient point 6 is arranged on the central point of housing 1 bottom, groove 5 be "
" the type structure,
The top of type groove 5 is circular arc 7 transition structures.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
1. capacitor, comprise housing, be arranged on the interior capacitor body of housing, cover cover plate and setting binding post on the cover board on housing, it is characterized in that: described housing bottom is provided with groove, be provided with salient point in groove, described groove extends to the center by the edge of housing bottom.
2. a kind of capacitor according to claim 1, it is characterized in that: described salient point is arranged on the central point of housing bottom.
