Abstract
The utility model relates to a kind of capacitor cover plate, comprise body, basis is provided with the scolding tin hole for scolding tin binding post, the body surface of described scolding tin hole surrounding upwardly, form a bowl-shape circle, described bowl-shape corral boxing tin hole, described body is provided with an annular groove, and described annular groove is around bowl-shape circle.The advantage of a kind of capacitor cover plate that the utility model provides is: by arranging a bowl-shape circle at body surface, bowl-shape corral boxing tin hole, and body is arranged an annular groove, described annular groove is around bowl-shape circle, when scolding tin, scolding tin can accumulate in together by bowl-shape circle, effectively prevent rosin joint, the phenomenon of solder skip occurs, and when liquid liquid overflows bowl-shape circle, gathering by annular groove, the phenomenon Anywhere effectively preventing liquid tin from flowing to body surface occurs, liquid tin is controlled at annular groove interior zone, thus do not need the liquid tin flowed out to remove, without the need to secondary operations, thus enhance productivity.
Description
Technical field
The utility model relates to capacitor technology field, particularly relates to a kind of capacitor cover plate.
Background technology
Capacitor is commonly referred to electric capacity, and electric capacity is also called " capacitance ", refers to the electric charge reserves under given potential difference, is designated as C, and international unit is farad (F).In general, electric charge in the electric field can be stressed and move, and between conductor, had medium, then hindering electric charge moves and make charge accumulation on conductor, causes the accumulation of electric charge to store, and the quantity of electric charge of storage is then called electric capacity.Electric capacity is one of a large amount of electronic component used in electronic equipment, is widely used in every the aspect such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuit.
In prior art, capacitor cover plate is generally equipped with the through hole for tin welding terminal, but but partial through holes is for directly on the cover board to wear a circular hole, when scolding tin, be easy to make tin on the cover board derive flowing, bother very much for scolding tin, and the situation of rosin joint may be caused to occur, cause quality dissatisfaction, and unsightly, thus the body surface of through hole surrounding is arranged annular protrusion by technician, form a groove, prevent the phenomenon causing rosin joint from occurring, but this device is in welding process, when liquid tin amount is excessive, the liquid tin overflowed in annular protrusion directly flows to body surface, need secondary operations, thus the operating efficiency reduced.
Utility model content
In view of this, be necessary to provide a kind of operating efficiency improving scolding tin, do not need secondary operations, and prevent the capacitor cover plate that rosin joint phenomenon occurs.
The utility model realizes like this, a kind of capacitor cover plate, comprise body, basis is provided with the scolding tin hole for scolding tin binding post, the body surface of described scolding tin hole surrounding upwardly, forms a bowl-shape circle, described bowl-shape corral boxing tin hole, described body is provided with an annular groove, and described annular groove is around bowl-shape circle.
Further, described annular groove is concentric with bowl-shape circle, and the arcuation in the cross section of annular groove.
Further, the outer of described body is provided with left-hand thread groove, and the notch of left-hand thread groove is downward.
The advantage of a kind of capacitor cover plate that the utility model provides is: by arranging a bowl-shape circle at body surface, bowl-shape corral boxing tin hole, and body is arranged an annular groove, described annular groove is around bowl-shape circle, when scolding tin, scolding tin can accumulate in together by bowl-shape circle, effectively prevent rosin joint, the phenomenon of solder skip occurs, and when liquid liquid overflows bowl-shape circle, gathering by annular groove, the phenomenon Anywhere effectively preventing liquid tin from flowing to body surface occurs, liquid tin is controlled at annular groove interior zone, thus do not need the liquid tin flowed out to remove, without the need to secondary operations, thus enhance productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of capacitor cover plate of the utility model;
Fig. 2 is that A-A in Fig. 1 is to cutaway view.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See also Fig. 1 and Fig. 2, wherein Fig. 1 is the structural representation of a kind of capacitor cover plate of the utility model, and Fig. 2 is that A-A in Fig. 1 is to cutaway view.
Described a kind of capacitor cover plate, comprise body 10, body 10 is provided with the scolding tin hole 20 for scolding tin binding post, body 10 surface of described scolding tin hole 20 surrounding upwardly, form a bowl-shape circle 30, described bowl-shape circle 30 is around scolding tin hole 20, and described body 10 is provided with an annular groove 11, and described annular groove 11 is around bowl-shape circle 30.
Described annular groove 11 is concentric with bowl-shape circle 30, and the arcuation in the cross section of annular groove 11, when liquid tin enters in annular groove 11, liquid tin can be made to distribute along annular groove 11 bottom even of arcuation, after cooling, not only attractive in appearance, and not easily produce breakpoint and burr.
The outer of described body 10 is provided with left-hand thread groove 12, and the notch of left-hand thread groove 12 is downward, is convenient to fasten with capacitor case edge.
By arranging a bowl-shape circle 30 on body 10 surface, bowl-shape circle 30 is around scolding tin hole 20, and body 10 is arranged an annular groove 11, described annular groove 11 is around bowl-shape circle 30, when scolding tin, scolding tin can accumulate in together by bowl-shape circle 30, effectively prevent rosin joint, the phenomenon of solder skip occurs, and when liquid liquid overflows bowl-shape circle 30, by gathering of annular groove 11, the phenomenon Anywhere effectively preventing liquid tin from flowing to body 10 surface occurs, liquid tin is controlled at annular groove 11 interior zone, thus do not need the liquid tin flowed out to remove, without the need to secondary operations, thus enhance productivity.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
