The utility model provides a embolism for insulating application of metal-back, it can seal under the condition that the metal-back does not produce the deformation, and the enclosed construction firm in connection, easy dismounting, the cost is lower.
Description
Technical Field
The utility model relates to a embolism for metal-back insulation application.
Background
The lithium battery inside the metal case of the vehicle-mounted lithium battery needs to be energized with the outside because the outside of the metal case is used in combination with other batteries and needs to be insulated. Conventionally, insulation is achieved by winding an insulating film around the outside of a metal case, and generally, the manufacturing is simplified and the cost can be reduced by thinly attaching an insulator to the outside of the case by electrodeposition coating.
However, in the process of coating the insulator, the insulator may enter the inside of the metal case, and in order to prevent the insulator from entering the inside, the inside of the metal case must be sealed. The existing sealing operation often causes the deformation of the metal shell, and has poor sealing effect and high cost.
Disclosure of Invention
The utility model aims to solve the technical problem that, overcome prior art not enough, provide a embolism for the insulating application of metal-back, it can seal under the metal-back condition that does not produce the deformation, and the enclosed construction firm in connection, easy dismounting, the cost is lower.
In order to solve the technical problem, the technical scheme of the utility model is that:
a plug for insulating coating of a metal shell comprises a plug body, an air pipe and a wire, wherein an air vent and a wire hole are formed in the axial direction of the plug body, one end of the air pipe is inserted into the air vent, the other end of the air pipe is located on the outer side of the plug body, and the wire is inserted into the wire hole and penetrates through the whole plug body.
Further, the outer diameter of the plug body decreases progressively from the upper end to the lower end of the plug body.
Further, the outer diameter of the air tube is larger than the inner diameter of the vent hole.
Further, the outer diameter of the lead is larger than the inner diameter of the lead hole.
Further, the plug body is made of rubber.
Further, the periphery of the upper end of the plug body is provided with a lap.
Having adopted above-mentioned technical scheme, the utility model discloses a embolism body of rubber material can not cause influences such as deformation to the metal casing during the operation. Set up air vent and air hose on the embolism body, utilize atmospheric pressure, make the embolism body adhesive force on the metal-back opening bigger, connect and become more fastening, the closure effect is better, and is also easier to the dismantlement of embolism body after the application, can reduction in production cost.

Detailed Description
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.
As shown in fig. 1 to 4, a plug for insulating coating of a metal shell comprises a plug body 1, an air tube 2 and a lead 3, wherein the plug body 1 is made of deformable rubber, and the outer diameter of the plug body 1 is gradually reduced from the upper end to the lower end of the plug body 1. When the plug is used, the plug is plugged into the metal shell 4, the plug body 1 is softer than the metal shell 4, and even if the plug body 1 deforms, the plug body can be plugged into the metal shell from the opening of the metal shell 4 and has corresponding hardness.
As shown in fig. 1 and 2, a vent hole 11 and a wire guide hole 12 are axially formed in the plug body 1, one end of the air tube 2 is inserted into the vent hole 11, the other end of the air tube 2 is located at the outer side of the plug body 1, and the wire 3 is inserted into the wire guide hole 12 and penetrates through the whole plug body 1.
As shown in fig. 2, the lead 3 is inserted into the lead hole 12 of the metal shell 4 and penetrates through the plug body 1, and the outer diameter of the lead 3 is larger than the inner diameter of the lead hole 12, so that no gap is generated between the lead 3 and the plug body 1, and the sealing effect is achieved. The length of the lead 3 entering the metal shell 4 is the length of the lead 3 contacting the bottom of the metal shell 4, and the part of the lead 3 outside the metal shell 4 is electrified with external connection.
As shown in fig. 2, the outer diameter of the air tube 2 is larger than the inner diameter of the vent hole 11, the air tube 2 can be sealed after being inserted into the vent hole 11, and in order to maintain the state of low pressure inside the metal shell 4, the air in the metal shell 4 is pumped out through the air tube 2, and then the air tube 2 is clamped by a clamp so that the air cannot enter or exit.
As shown in fig. 3 and 4, when the periphery of the opening of the metal shell 4 is not insulated, a ring of rubber overlap 13 extending outward may be provided on the periphery of the upper end of the plug body 1 to perform an insulating function.
Before coating, pumping a certain proportion of gas out of the air tube 2, clamping the air tube 2 by using a clamp to keep the interior of the metal shell 4 in a low-pressure state, enabling the plug body 1 to be tightly attached to the metal shell 4, and then coating insulating paint on the outer surface of the metal shell 4; after the application of the insulating paint is completed, the clamp of the air tube 2 is removed to make the air pressure inside the metal case 4 higher than the outside air pressure, so that the plug and the metal case 4 can be separated.
The above-mentioned embodiments further explain in detail the technical problems, technical solutions and advantages solved by the present invention, and it should be understood that the above only is a specific embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
