Description

Metal Hybrid Rubber

[0001] The present invention relates to a metal hybrid rubber seal for a capacitor, and more specifically, to a metal hybrid rubber seal capable of preventing short circuits between lead wires and a metal reinforcing plate by separately forming holes through which cathode and anode lead wires of a capacitor pass and holes for fixing a metal reinforcing plate.

[0002] To prevent leakage of the internal electrolyte, capacitors seal the inside of the case with a rubber seal placed on the end of the cylindrical case. Due to its flexible nature, the rubber seal can bend flexibly as the capacitor expands in high-temperature environments, potentially causing leakage of the internal electrolyte.

[0003] To prevent this, a product was developed that prevents the rubber plug (10) from being flexibly bent by placing a metal reinforcing plate (20) on top of the rubber plug (10) as shown in (a) of Fig. 1. However, since the rubber plug (10) uses a single forming pin to form a through hole (12) through which a lead wire passes while fixing the metal reinforcing plate (20) during the manufacturing process, the rubber plug (10) is manufactured with a slope formed on the upper inner side of the through hole (12), and the uppermost end of the sloped portion of the through hole (12) is structured to be placed in contact with the metal reinforcing plate (20).

[0004] In the conventional rubber seal having the above structure, a slope is formed at the top of the through hole (12) and a metal reinforcing plate (20) is placed adjacent to the top of the slope. Therefore, when a lead wire passing through the through hole (12) is bent as shown in (b) of Fig. 1, there is a problem in that a short circuit occurs because the lead wire comes into contact with the metal reinforcing plate (20).

[0005] Accordingly, there is a growing need for a metal hybrid rubber seal having a structure that can stably and firmly fix the metal reinforcing plate during the rubber seal forming process while preventing short circuits between the lead wire and the metal reinforcing plate.

[0006] The present invention has been devised to solve the above-mentioned problems, and an object of the present invention is to provide a metal hybrid rubber conductor having a structure capable of preventing short circuits between negative and positive lead wires and a metal reinforcing plate.

[0007] Another object of the present invention is to provide a metal hybrid rubber seal with improved adhesiveness between a rubber plate and a metal reinforcing plate.

[0008] Meanwhile, other purposes not specified in the present invention may be additionally considered within a range that can be easily inferred from the detailed description and effects described below.

[0009] The metal hybrid rubber jacket according to the present invention is a metal hybrid rubber jacket for a capacitor in which a main body made of a rubber material and a reinforcing part made of a metal material are integrally formed on the upper part of the main body, wherein the main body includes two through holes through which positive and negative lead wires pass, and a plurality of fixing holes arranged at different positions from the through holes, and the reinforcing part may include a main hole having a diameter arranged close to the upper circumference of the through holes, and a sub hole having a diameter arranged adjacent to the upper circumference of the fixing holes.

[0010] Here, the through hole and the fixing hole can be arranged in a direction in which their extension lines are perpendicular to each other, and the fixing hole can be manufactured to slope downward inward from the top.

[0011] The metal hybrid rubber seal according to the present invention is arranged such that the uppermost circumference of the through hole of the main body and the uppermost circumference of the main hole of the reinforcement part are spaced apart by a certain length, so that even if the lead wire passing through the through hole is bent, it does not come into contact with or be adjacent to the main hole of the reinforcement part, thereby safely preventing a short circuit due to the contact between the lead wire and the reinforcement part.

[0012] In addition, since the through holes and fixing holes of the main body are formed with a step difference from the main holes and sub holes of the reinforcement part, the adhesive strength between the main body and the reinforcement part is improved.

[0020]

[0021] Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the drawings.

[0022] Fig. 2 shows a perspective view of a metal hybrid rubber seal (100) according to one embodiment of the present invention, and Fig. 3 shows an exploded perspective view of a metal hybrid rubber seal (100) according to one embodiment of the present invention. Fig. 4 shows cross-sectional views of BB and CC shown in Fig. 2, respectively.

[0023]

[0024] A metal hybrid rubber seal (100) according to one embodiment of the present invention is manufactured by integrally forming a main body (200) made of rubber and a reinforcing part (300) made of metal on the upper part of the main body (200).

[0025] The main body (200) includes two through holes (210) through which the positive and negative lead wires pass, and a plurality of fixing holes (220). The through holes (210) are formed by penetrating the interior of the main body (200) by a forming pin (not shown) provided in a forming device during the manufacturing process of the rubber cap (100). The through holes (210) are passages through which the negative and positive lead wires of the capacitor pass. The through holes (210) are formed in a cylindrical shape with the same diameter at the upper and lower ends. It is preferable that two through holes (210) are provided from the main body (200), and they may be arranged in a state where they are spaced apart from each other at a certain distance in the left and right or up and down directions from the main body (200).

[0026]

[0027] The fixing hole (220) is a part formed by a fixing pin (not shown) provided in a molding device during the manufacturing process of the rubber plate (100). The fixing pin is a member into which the sub-hole (320) of the reinforcing part (300) is inserted to fix the position of the reinforcing part (300) during press molding of the rubber plate formed by the reinforcing part (300) and the main body (200) made of a metal material. In order for the sub-hole (320) of the reinforcing part (300) to be easily inserted and fixed into the fixing pin, the fixing pin may be manufactured in the shape of a lower light shaft.

[0028] The fixing hole (220) may be formed in the form of a groove that penetrates only a portion of the main body (200). The fixing hole (220) formed through a fixing pin in the shape of a lower light shaft is composed of an inclined portion (222) that slopes downward from the top to the inside and a wall portion (224) that extends downward from the inclined portion (222). It is preferable that two fixing holes (220) are provided from the main body (200), and they may be arranged in a state where they are spaced apart from each other at a certain distance in the left-right or up-down direction from the main body (200).

[0029] At this time, the through holes (210) and the fixing holes (220) can be arranged at different positions so that their extension lines can be perpendicular to each other. For example, if two through holes (210) are arranged spaced apart in the left and right directions of the main body (200), two fixing holes (220) can be arranged spaced apart in the top and bottom directions of the main body (200).

[0030]

[0031] The reinforcing member (300) is in the form of a plate made of a metal material and includes a plurality of main holes (310) and a plurality of sub holes (320). The main hole (310) has a diameter arranged close to the upper circumference of the through hole (210). That is, the uppermost circumference of the through hole (210) and the uppermost circumference of the main hole (310) are arranged in a state where they are spaced apart by a certain length, so that even if the lead wire passing through the through hole (210) is bent, it does not come into contact with or be adjacent to the main hole (310) of the reinforcing member (300), thereby having the advantage of safely preventing a short circuit due to the contact of the lead wire and the reinforcing member (300). It is preferable that two main holes (310) are provided from the reinforcing member (300), and they can be arranged in a state where they are spaced apart from each other by a certain distance in the left-right or up-down direction from the reinforcing member (300).

[0032]

[0033] The sub-hole (320) has a diameter that is arranged adjacent to the upper circumference of the fixing hole (220). That is, the uppermost circumference of the fixing hole (220) and the uppermost circumference of the sub-hole (320) can be arranged adjacent or in contact with each other. This is because the sub-hole (320) of the reinforcing member (300) is formed in a state in which it is inserted and fixed by a fixing pin (not shown), so that the uppermost circumference of the fixing hole (220) and the uppermost portion of the sub-hole (320) are arranged in contact with each other. It is preferable that two sub-holes (320) are provided from the reinforcing member (300), and they can be arranged in a state in which they are spaced apart from each other at a certain distance in the left-right or up-down direction from the reinforcing member (300).

[0034] At this time, the main holes (310) and the sub holes (320) can be arranged at different positions so that their extension lines can be perpendicular to each other. For example, if the two main holes (310) are arranged spaced apart in the left and right directions of the reinforcement part (300), the two sub holes (320) can be arranged spaced apart in the upper and lower directions of the reinforcement part (300).

[0035]

[0036] In addition, the metal hybrid rubber seal (100) according to one embodiment of the present invention has the effect of improving the adhesive force between the main body (200) and the reinforcement part (300) because the through hole (210) and the fixing hole (220) of the main body (200) are formed with a step difference from the main hole (310) and the sub hole (320) of the reinforcement part (300).
