Description

A kind of unilateral explosion-proof cylindrical capacitive

Technical field

The utility model is related to a kind of capacitors, are specifically a kind of unilateral explosion-proof cylindrical capacitive.

Background technology

Existing explosion prevention capacitor generally sets weld tabs in double weld tabs welding wire connection terminal bottom, and spacers block welds in utilization Piece, when capacitance expands, wire connection terminal stress is disconnected in annular indentation, there, so as to fulfill the explosion prevention function of capacitance.But cylinder The inner space of shape capacitance is smaller, it is difficult to install explosion-protection equipment simultaneously in two wire connection terminals, explosion-proof dress is installed in part simultaneously The cylindrical capacitive put also because adjacent weld tabs is got too close to, easily occurs short circuit accident, causes capacitor direct short-circuit quick-fried It is fried, it loses more than gain.

Therefore, it is necessary to be further improved.

Utility model content

The purpose of the utility model is to overcome above-mentioned the shortcomings of the prior art, and provide a kind of unilateral explosion-proof cylinder Shape capacitance by the First Line ear that bending is set in the first wire connection terminal and annular notch, sets in the second wire connection terminal and hangs down The second straight line ear, allows the present embodiment to accomplish in the limited inner space of cylindrical capacitive not only explosion-proof, but prevent line ear it Between get too close to occur short circuit accident.

What the purpose of this utility model was realized in：

A kind of unilateral explosion-proof cylindrical capacitive, including the first wire connection terminal, the second wire connection terminal and capacitance cover, capacitive surface Lid is fixedly connected with first and second wire connection terminal, and the bottom of the first wire connection terminal is equipped with the First Line ear of bending, the second wire connection terminal Bottom be equipped with the second vertical line ear, the first wire connection terminal is equipped with annular notch, and the upper end of first and second line ear is equipped with interval Plate, middle partition plate 4 are fixedly connected with capacitance cover 2.

The included angle A of the center line of the First Line ear and the center line of the first wire connection terminal is 70 ° -90 °.

First and second wire connection terminal is fixedly connected by clamp device and terminal moulding with capacitance cover.

The beneficial effects of the utility model are：

By the First Line ear that bending is set in the first wire connection terminal and annular notch, set in the second wire connection terminal vertical The second line ear, the present embodiment is allow to accomplish in the limited inner space of cylindrical capacitive not only explosion-proof, but also prevented between line ear It gets too close to that short circuit accident occurs, meanwhile, because reducing the annular notch processing to the second wire connection terminal, it is possible to reduce production Cost.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and embodiments.

Referring to Fig. 2-Fig. 3, this unilateral explosion-proof cylindrical capacitive, including the first wire connection terminal 11,12 and of the second wire connection terminal Capacitance cover 2, capacitance cover 2 are fixedly connected with first and second wire connection terminal, and the bottom of the first wire connection terminal 11 is equipped with the of bending One line ear 31, the bottom of the second wire connection terminal 12 are equipped with the second vertical line ear 32, and the first wire connection terminal 11 is equipped with annular notch 111, the upper end of first and second line ear is equipped with middle partition plate 4, and middle partition plate 4 is fixedly connected with capacitance cover 2, by the first terminals Son 11 sets the First Line ear 31 of bending and annular notch 111, and the second vertical line ear 32 is set in the second wire connection terminal 12, is made The present embodiment can be accomplished not only explosion-proof in the limited inner space of cylindrical capacitive, but also prevent from getting too close to occur between line ear short Road accident, meanwhile, the annular notch 111 of the second wire connection terminal 12 is processed because reducing, it is possible to reduce production cost

When capacitance is because of failure, capacitance can swell in itself, and first and second wire connection terminal is caused to occur relatively with middle partition plate 4 Displacement, the First Line ear 31 on the first wire connection terminal 11 offset with middle partition plate 4 due to being bent over, cause in the first wire connection terminal 11 Larger pulling force is generated, annular notch 111 will disconnect under the action of pulling force, so that the first wire connection terminal 11 fails, first In the case that wire connection terminal 11 fails, the second wire connection terminal 12 is also natural to work, explosion-proof so as to achieve the effect that.

Further, the included angle A of the center line of the center line of First Line ear 31 and the first wire connection terminal 11 is 70 ° -90 °, During production can according to capacitance need explosion-proof degree make adjustment to angle, in the present embodiment the center line of First Line ear 31 with The angle of the center line of first wire connection terminal 11 is 90 °.

Further, first and second wire connection terminal is fixed with capacitance cover 2 by clamp device 5 and terminal moulding 6 and connected It connects, improves the bonding strength of wire connection terminal and capacitance cover 2, terminal moulding 6 can also play water-proof function.

Above-described embodiment is the preferred embodiment of the utility model, and the utility model can also have other embodiments.Ability The technical staff in domain can also make equivalent variations or replacement on the premise of without prejudice to the utility model spirit, these equivalent changes Type or replacement are all contained in the scope set by the application claim.
