Please read shown in Figure 1, it is a kind of known capacitor constructions, mainly be by valve jacket 91, dielectric medium 92, inner cover plate 93, outer cover plate 94 constitutes, mainly be that dielectric medium 92 is inserted in the room 811 of valve jacket 91, after adding electrolyte, with two perforation, 931 kisses of inner cover plate 93 for two pins 321 of dielectric medium 92, inner cover plate 93 is placed on the valve jacket 91, after filling glue on the inner cover plate 93, again with two perforation, 941 kisses of outer cover plate 94 for two pins 921 of dielectric medium 92, make two pins 921 of two perforation, 941 kisses of outer cover plate 94 for dielectric medium 92, it is last and bonding that outer cover plate 94 is covered in about inner cover plate.

The known capacitor manufacture of this kind, when dielectric medium 92 is inserted in the room 911 at valve jacket 91 and after pouring into electrolyte, room 911 walls of this valve jacket 91 can attach electrolyte, therefore, inner cover plate 93 and outer cover plate 94 can't be very firm be bonded in this valve jacket 91, and then this dielectric medium 92 also is easy to cause this capacitor to lose efficacy by 91 disengagings of this valve jacket.

The purpose of this utility model is to provide a kind of chip-type capacitor, mainly is the inwall position that closely is attached to room with elastomer, and is reliable in conjunction with the location to reach dielectric medium, also simple structure and easy to manufacture.

The purpose of this utility model is achieved in that a kind of chip-type capacitor, it is characterized in that: comprise valve jacket, dielectric medium, elastomer and cover plate, wherein valve jacket forms the shell body of capacitor, is provided with an open room, and the opening of this valve jacket forms a ringwall frame; Dielectric medium is placed in the room of valve jacket, and this dielectric medium has two pins; Elastomeric external diameter is slightly larger than the internal diameter of room inwall, and elastomer has more than two perforation and the pin by dielectric medium; Cover plate is combined in the wall frame of valve jacket, and cover plate is established two perforation and passed the pin of dielectric medium.

The wall frame of described valve jacket is provided with short slot.

The convex body of protrusion is established at the open circumferential position that described valve jacket is established room.

The pin section configuration of described dielectric medium forms circle or rectangle.

Two perforation of described cover plate are provided with groove, and groove extends to cover plate end limit, and matches with the set short slot of wall frame of valve jacket.

Described cover plate and valve jacket are to fix, adhere in the ultrasonic waves mode.

Owing to adopt such scheme: dielectric medium is reliable in conjunction with the location, also simple structure and easy to manufacture.

See also appended graphicly, the following example explanation lifted in this creation:

Fig. 1 commonly uses the exploded perspective view of structure.

Fig. 2 the utility model exploded perspective view.

Fig. 3 a kind of combination situations profile of the present utility model.

Fig. 4 another kind of combination situations profile of the present utility model.

Please read shown in second figure, the utility model is to include members such as valve jacket 1, dielectric medium 2, elastomer 3 and cover plate 4 to constitute.

Valve jacket 1 is the shell that forms capacitor, make by tool insulation material, it is comparatively suitable that this valve jacket 1 itself forms upright profile, has open room 11 in the valve jacket 1, it is comparatively suitable that this room 11 forms circle, room 11 can hold to go into for dielectric medium 2 and elastomer 3, this elastomer 3 can be formed be linked in closely in the room 11; The openend tool one ringwall frame 12 of valve jacket 1 can hold to go in this wall frame 12 for cover plate 4, and in case of necessity, this valve jacket 1 is provided with the convex body 13 of protrusion at the open circumferential position of this room 11, and this wall frame 12 can be established short slot 14.

Dielectric medium 2 is to be known structure, is to have two pins 21, and this dielectric medium 2 is the rooms 11 that can insert at valve jacket 1, and its pin 21 can stretch out outside valve jacket 1, and this two pin 21 can be circular for section configuration or the post of rectangle.

Elastomer 3 is can be by rubber, the deformable body that materials such as silica gel are made, this elastomeric external diameter is the internal diameter that is slightly larger than valve jacket 1 room 11, and this elastomer 3 can be compressed its external diameter that diminishes, when this elastomer 3 is being compressed when diminishing, can easily be held to go in the room 11 of valve jacket 1, and when the pressure that elastomer 3 is compressed diminish disappears, this elastomer can dilatancy restore to the original state, form this restorable elastomer 3 and can be adjacent to location in room 11 closely, elastomer 3 is provided with more than two perforation 31, is passed through by two pins 21 for dielectric mediums 2 of two perforation 31 wherein.

Cover plate 4 is in order to the closure of openings with valve jacket 1, this cover plate 4 is can be combined in the wall frame 12 of valve jacket 1, in the middle of preferred embodiment, 12 of the wall frames of this cover plate 4 and valve jacket 1 can be fixed with modes such as various fixing, adhesions and be combined in valve jacket 1, in the middle of preferred embodiment, cover plate 4 is to be fixed on valve jacket 1 in the ultrasonic waves mode, and the convex body 13 of valve jacket 1 can increase the adhesive surface of cover plate 4 and valve jacket 1, makes cover plate 4 more firm with combining of valve jacket 1; Cover plate 4 tool two perforation 41 own, this two perforation 41 can pass for two pins 21 of dielectric medium 2, in case of necessity, establish the end limit that groove 42 extends to cover plate 4 by this two perforation 41, and this groove 42 can be fit to the short slot 15 of valve jacket 1.

Please read shown in Figure 3, it is this combination situations of creating a preferred embodiment, it is the room 11 that dielectric medium 2 can be inserted at valve jacket 1, reach the pin 21 that 31 pairs of elastomeric perforation is positioned at dielectric medium 2, the pin 21 that supplies dielectric medium 2 is earlier after flattening, pass by this perforation 31 again, because the external diameter of this elastomer 3 is greater than room 11 internal diameters of valve jacket 1, therefore, when being placed in the room 11, this elastomer 3 can expand into the size of recovering original outside diameter, form the inwall position that elastomer closely is attached to room 11, to reach assembling purpose in conjunction with the location.In addition, in the middle of preferred embodiment, this elasticity originally 3 also can combine with dielectric medium 2 earlier, also the pin 21 that is about to dielectric medium 2 passes elastomeric perforation 31, with modes such as tools elastomer 3 is compressed so that external diameter diminishes then, the elastomer 3 that simultaneously external diameter is diminished is inserted in the room 11 of valve jacket 1, when the strength that elastomer 3 external diameters are diminished disappears, this elastomer 3 promptly can expand and expand the restorable room 11 inwall positions that closely are fixed on, at this moment, again cover plate 4 is fixed in the wall frame 13 of valve jacket 1, wherein, and for example aforementioned fixing suitable with supersonic adhesion system, at this moment, the pin 21 of dielectric medium 2 is stretched out by the perforation 41 of cover plate 4, and when this pin that stretches out 21 was not bent, this capacitor can use as the capacitor of general plate.

Please read shown in Figure 4, when being bent by cover plate 4 perforation 41 pins that stretch out 21, and pin 21 most heavy this grooves 42 that place that this quilt bends, therefore what 21 of this pins had a less part protrudes from cover plate 4 surfaces, so, this capacitor goes for the surface adhering technology (S.M.T) of automated process.

Capacitor constructions of the present utility model is to have simple structure, and advantage easy to manufacture, again and, after this capacitor manufacturing is finished, do not have the problem of coming off yet.

The utility model can not depart under the main spirit and feature, implements with other different form.Therefore, above-mentioned preferred embodiment is just enumerated by way of example, and it should be considered as restriction of the present utility model.Scope of the present utility model is defined by claim, but not is decided view by the content of specification.
