Description
Technical field
The invention belongs to capacitor technology field, especially relate to a kind of capacitor.
Background technology
Capacitor is to consist of two electrodes and dielectric material therebetween.Dielectric material is a kind of dielectric, when be placed in two with the electric field between the parallel plate electrode of the equivalent charges of different polarity in time, due to polarization, at dielectric surface, produce polarization charge, then make to be strapped in the corresponding increase of electric charge on pole plate, the potential difference maintaining between pole plate is constant.
As shown in Figure 1, in original capacitor, the shell 1 ' of capacitor is cylindric, on the outer peripheral face of the port of shell 1 ', be provided with installation portion 4 ', on installation portion 4 ', offer the mounting groove 5 ' for installing, lead-out wire 3 ' in capacitor stretches out from the port of shell 1 ', during application, installation portion 4 ' need to be inserted on installing rack, on installing rack, need to offer wire hole, lead-out wire needs after stretching out from wire hole to be connected in circuit after bending.
The installation portion of above-mentioned capacitor is arranged on port and is annular, generally adopting the port that makes made of plastic is easily out of shape and is ellipticity, thereby easily location is inaccurate while being installed on installing rack, secondly, lead-out wire needs after drawing from wire hole to unroll behind the bottom of capacitor and just can be connected in circuit, thereby lead-out wire needs to lengthen, cause waste, and increased cost.
Summary of the invention
The object of this invention is to provide a kind of capacitor, it has accurate positioning, the feature reducing costs.
The technical solution adopted in the present invention is: a kind of capacitor, comprise shell, electric capacity in the enclosure and the lead-out wire of drawing from electric capacity are installed, it is characterized in that, described shell is cylindric, comprise bottom, perpendicular to the barrel of bottom be arranged on the openend of the barrel other end, described bottom stretches out and forms circular installation portion to the bending of barrel side, described installation portion and barrel concentric, and the height of installation portion is less than the height of barrel, on described installation portion, offer annular mounting groove, described lead-out wire stretches out from openend.
In above-mentioned a kind of capacitor, the inner side of described barrel offers location notch near openend, in described location notch, diaphragm seal is installed, and on described diaphragm seal, offers through hole, and described lead-out wire is drawn from through hole.
In above-mentioned a kind of capacitor, described mounting groove is opened on the lateral wall of installation portion, and the diameter of described mounting groove is less than the external diameter of installation portion.
In above-mentioned a kind of capacitor, between described installation portion and the outside of barrel, be provided with reinforcement.
The advantage that compared to the prior art the present invention had is:
1, the bottom of sealing is set, and lead-out wire stretches out from the openend of shell, has reduced the length of lead-out wire, has reduced cost, and meanwhile, lead-out wire can be directly connected in circuit, easy for installation.
2, installation portion is set, facilitates electric capacity to be plugged into the place of installation, installation portion length is short, not yielding, dimensionally stable, and installation strength is high, installs stable.
3, diaphragm seal is set, facilitates lead-out wire to concentrate outlet, lead-out wire can arrange node at diaphragm seal place, prevents that lead-out wire from deviating from, and pulls apart.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the structural representation of existing capacitor.
Fig. 2 is the structural representation of capacitor in embodiments of the invention.
Fig. 3 is the sectional structure schematic diagram of embodiments of the invention housing.
In figure: shell 1; Barrel 11; Bottom 12; Openend 13; Installation portion 14; Location notch 15; Mounting groove 16; Reinforcement 17; Lead-out wire 2; Diaphragm seal 3; Through hole 31.
Embodiment
Embodiment, see shown in Fig. 2 and Fig. 3: a kind of capacitor, comprise shell 1, the lead-out wire 2 that is arranged on the electric capacity in shell 1 and draws from electric capacity, shell 1 is cylindric, comprise bottom 12, barrel 11 and the openend 13 that is arranged on barrel 11 other ends perpendicular to bottom 12, bottom 12 stretches out and forms circular installation portion 14 to barrel 11 side bendings, installation portion 14 and barrel 11 concentrics, and the height of installation portion 14 is less than the height of barrel 11, on installation portion 14, offer annular mounting groove 16, mounting groove 16 is opened on the lateral wall of installation portion 14, the diameter of mounting groove 16 is less than the external diameter of installation portion 14, the inner side of barrel 11 offers location notch 15 near openend 13, the diaphragm seal 3 of annular is installed in location notch 15, the center of diaphragm seal 3 offers through hole 31, lead-out wire 2 is drawn from through hole 31.
Between the outside of installation portion 14 and barrel 11, be provided with some reinforcements 17, reinforcement 17 is along the axial distribution of barrel 11.
Lead-out wire 2 is drawn from the through hole 31 of diaphragm seal 3, can avoid lead-out wire 2 from the end of electric capacity around being connected in circuit to bottom 12, saved the length of this part lead-out wire 2, reduced cost; In syndeton, there is change, original design, when capacitor is plugged in installing rack, installing rack need to arrange groove or the hole of an outlet, capacitor bottom 12 sealings of the present invention's design, can directly detain the dead position installing, and need not consider the position in groove or hole, also avoided the defect of electric capacity meeting pinch off lead-out wire 2 when installing rack rotates, easy for installation; On openend 13, be provided with diaphragm seal 3, both located the position of lead-out wire 2, meanwhile, lead-out wire 2 is tied a knot or buckle is set between diaphragm seal 3 and electric capacity, can prevent the stressed excessive and thing of pulling apart of lead-out wire 2, ensure lead-out wire 2 safety in utilization of capacitor; Installation portion 14 and barrel are arranged for 11 minutes, and guarantee the bonding strength of capacitor, reduced the requirement of capacitor to the wall thickness of shell 1 simultaneously, reduce costs; In the inner side of openend 13, location notch 15 is set, diaphragm seal 3 is installed simple, it is firm to install; Reinforcement 17 can be strengthened the stability of the shape of installation portion 14 and barrel 11, and versatility is good.
These are only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
