In the figure, 1, a main body; 2. a sealing section; 3. a seal ring; 4. sealing the barb portion; 5. a hook portion; 6. an elastic groove; 7. chamfering; 8. and pressing the gasket.

Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

As shown in fig. 1 and 2, the novel rubber plug comprises a main body 1 and a sealing section 2 axially extending from the bottom of the main body 1 and sealing the end part of a capacitor, wherein a plurality of layers of sealing devices are arranged on the peripheral wall of the sealing section 2 and between the sealing section and the capacitor, a plurality of sealing grooves for fixedly mounting the corresponding sealing devices are formed in the sealing section 2, a sealing ring 3 arranged in the sealing grooves is arranged at the inner end of the sealing device, a sealing barb part 4 matched with the sealing of the capacitor is formed by outwards bending and extending the sealing ring 3, a bent hook part 5 is formed at the inner end of the sealing barb part 4, an elastic groove 6 is formed between the bent hook part 5 and the sealing barb part 4, the sealing barb part 4 is extruded towards the direction of the bent hook part 5 in the process of filling the rubber plug into the end part of the capacitor, the range of the elastic groove 6 is reduced, the sealing barb part 4 is finally forced to be tightly pressed on the bent hook part 5 to form point-to-point contact sealing, and the outer wall of the sealing barb part 4 has certain supporting property under the condition of mutual force, and the sealing barb part forms high sealing property with the capacitor, and the stability is improved.

Preferably, the bottom end of the sealing section 2 is provided with a chamfer 7.

Further, the bottom of the main body 1 is further provided with a pressing pad 8 for further improving the connection strength.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.

Although the terms of the body 1, the seal segment 2, the seal ring 3, the seal barb 4, the hook 5, the elastic groove 6, the chamfer 7, the press-fit washer 8, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely for convenience in describing and explaining the nature of the utility model; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present utility model.
