Description

Novel waterproof rubber ring

Technical Field

The utility model relates to the technical field of lithium batteries, in particular to a novel waterproof rubber ring.

Background

With the rapid development of new energy, more and more new products emerge. Mobile phones, watches, cars, drones, dust collectors, shared power-assisted vehicles, shavers, etc. all require increasingly higher levels of waterproofing. For the power battery products with the sockets leaking outwards, the waterproof function is very important. When the power battery is soaked in water, short circuit and the like of an internal battery core can be caused, and phenomena such as smoking, fire, even explosion and the like can be caused. Most of the prior art do not have waterproof design, and some waterproof schemes also use modes such as glue filling, point gluing, poor stability, can't do over again.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide a novel waterproof rubber ring which can meet the waterproof standard above IP67, is easy to install, has high production efficiency, is suitable for most products with leaked sockets, and is easy to rework and disassemble.

The utility model is realized by the following modes:

a novel waterproof rubber ring comprises a waterproof rubber ring body 1, wherein the waterproof rubber ring body 1 is arranged in a corresponding through hole 21 on a shell 2; the central through hole 11 of waterproof rubber ring body 1 matches with socket 31 on PCB board 3, its characterized in that: a circle of closed stop ribs 12 are arranged on the side face of the waterproof rubber ring body 1 matched with the through hole 21; the bottom of the central through hole 11 extends towards the top in the circumferential direction and is gradually reduced in opening to form a flanging enclosing wall 13 with a thin-wall structure; the flanged perimeter wall 13 mates with the socket 31.

Further, a notch 14 is arranged at the top of the waterproof rubber ring body 1.

The utility model has the beneficial effects that: can satisfy waterproof standard more than IP67, the installation is simple and easy, and production efficiency is high, is suitable for the product that most sockets leaked outward, and easy reworking is easy to be dismantled.

Example (b):

as shown in fig. 1-3, a novel waterproof rubber ring comprises a waterproof rubber ring body 1, wherein the waterproof rubber ring body 1 is arranged in a corresponding through hole 21 on a shell 2; the central through hole 11 of waterproof rubber ring body 1 matches with socket 31 on PCB board 3, its characterized in that: a circle of closed stop ribs 12 are arranged on the side face of the waterproof rubber ring body 1 matched with the through hole 21; the bottom of the central through hole 11 extends towards the top in the circumferential direction and is gradually reduced in opening to form a flanging enclosing wall 13 with a thin-wall structure; the flanged perimeter wall 13 mates with the socket 31.

The waterproof rubber ring mainly uses materials such as ethylene propylene diene monomer, silicon rubber, nitrile rubber, chloroprene rubber, polytetrafluoroethylene, rubber and the like, and can be selected according to different use occasions. The body is the basis of the waterproof rubber ring, the base is used for pressing the PCB, and the gap between the waterproof rubber ring and the PCB is filled up, so that water is prevented from permeating; the notch 14-position yielding fool-proof characteristic ensures that the connector is correctly installed in place, and the prescription groove characteristic can be adjusted according to different products; the stop ribs 12 are positioned in the middle of the body and used for clamping the thickness of the body and the thickness of the shell base material; the root part of the flanging wall 13 and the base are integrated, the top part is a thin wall with a horizontal and vertical shape, and the flanging wall has double functions of stopping position and preventing water.

The waterproof rubber ring is arranged in the shell 2 from outside to inside, and the shell 2 is tightly clamped through the stop ribs 12; then, the socket 31 is pasted and welded on the PCB 3, and the PCB 3 is locked and attached with the shell 2 from the inside; finally, the front surface of the PCB 3 is completely attached to the base of the waterproof rubber ring, the first layer of protection is formed by compression deformation of the waterproof rubber ring to fill the gap between the waterproof rubber ring and the PCB, and the second layer of protection flanging enclosing wall 13 is attached to the periphery of the socket 31 to form a sealing protection body, so that a double-layer waterproof function is realized.

The socket can meet the waterproof standard above IP67, is easy to install, has high production efficiency, is suitable for most products with external leakage of the socket, and is easy to rework and disassemble.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
