Description

Technical Field

[0001] The present application relates to a cover plate, and in particular to a battery cover plate. Background Art

[0002] In some capacitors that require a large working current, a sealing ring is usually used to seal the motor before packaging. The installation connection structure between the conductive column electrode and the packaging cover plate usually adopts a mounting positioning hole and a positioning groove for the conductive column electrode to be led out on the packaging cover plate, and then the sealing ring is used to fill the space between the electrode and the cover plate. During this installation process, dust is easily adhered to the sealing ring, resulting in failure of the insulation performance, and the assembly tools of the sealing ring increase labor costs and material costs. In this regard, we propose a battery cover to solve the above problems. Utility Model Content

[0039] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0040] Figure 1-Figure 2 FIG. 1 shows a structural diagram of a battery cover 100 according to an embodiment of the present application. Figure 1-Figure 2 As shown, the battery cover 100 may include:

[0041] A light cover plate 110 having two through holes 111;

[0042] Two poles 120, the two poles 120 respectively pass through corresponding through holes 111 and are arranged on the optical cover plate 110;

[0043] A sealing layer 130 , the sealing layer 130 is filled in the through hole 111 to seal the gap between the pole 120 and the optical cover plate 110 ;

[0044] The adhesive layer 140 is located between the optical cover plate 110 and the pole 120 .

[0045] In this embodiment, when the optical cover 110 is used, the surface of the optical cover 110 is cleaned in advance and partially T-treated. After the treatment, the glue layer 140 is applied to the pole 120, and the pole 120 is installed on the optical cover 110 through the through hole 111. At this time, the glue layer 140 makes the optical cover 110 and the pole 120 bonded, and the through hole 111 is injected through the injection molding process, so that the injection molding material forms a sealing layer 130, and the pole 120 and the through hole 111 are sealed, thereby reducing the manual assembly of the sealing ring process, and at the same time canceling the sealing ring, reducing the material cost, and adopting the injection molding structure, which enhances the insulation performance of the optical cover 110, reduces the dust adhering to the sealing ring and causing the insulation performance to fail, and after the optical cover 110 is T-treated, the adhesion of the sealing layer 130 is increased, and the sealing performance of the product is more effectively guaranteed;

[0046] By setting the sealing layer 130, the sealing ring structure between the pole 120 and the light cover plate 110 is eliminated, the material cost is reduced, and at the same time, the manual assembly process of the sealing ring is reduced, and the labor cost is reduced. The sealing layer 130 is injection molded by an injection molding process, which increases the insulation performance of the cover plate and reduces the insulation performance failure caused by dust adhering to the sealing ring. After the light cover plate 110 is T-treated, the adhesion of the sealing layer 130 is increased, and the sealing performance of the product is more effectively guaranteed;

[0047] It should be noted that the T processing position of the light cover plate 110 is the peripheral surface of the through hole 111. The main process flow of the T treatment is: hang the light cover plate 110 and perform degreasing treatment, wash the surface of the light cover plate 110 with water for many times after the treatment is completed, perform pretreatment after the washing is completed, wash with water for many times after the treatment is completed, perform alkaline etching treatment after the washing is completed, wash with water twice after the treatment is completed, and then perform black removal (neutralization) treatment, wash with water again after black removal, and perform electrolysis treatment, ultrasonic cleaning and water washing 2 times after the electrolysis is completed, and baking is performed after the operation is completed. The treated light cover plate 110 is observed under a 1000x magnifying glass and is honeycomb-shaped, which enhances the adhesion of the injection molding process.

[0048] like Figure 1-Figure 2 As shown, in one embodiment,

[0049] The surface of the optical cover plate 110 has a plurality of honeycomb-shaped grooves.

[0050] In this embodiment, the processed optical cover plate 110 is observed under a 1000-fold magnifying glass and is in a honeycomb shape, which enhances the adhesion of the injection molding process.

[0051] like Figure 1 As shown, in one embodiment,

[0052] The cross section of the pole 120 is a "T"-shaped structure, and the pole 120 has a vertical rod and a horizontal rod, and the vertical rod portion of the pole 120 passes through the through hole 111;

[0053] The crossbar of the pole 120 is in contact with the optical cover 110 .

[0054] In this embodiment, the cross section of the pole 120 is an inverted "T"-shaped structure. The pole 120 has a vertical rod and a horizontal rod. The horizontal rod is in contact with the light cover 110 and is bonded by the adhesive layer 140. The vertical rod is located in the through hole 111. The sealing layer 130 is filled by an injection molding process to fix the pole 120 on the light cover 110. After processing, the surface of the light cover 110 has a plurality of honeycomb structures to enhance the adhesion with the adhesive layer 140 and the sealing layer 130.

[0055] like Figure 1 As shown, in one embodiment,

[0056] The sealing layer 130 is made of PPS rubber material, and fills the gap between the vertical rod of the pole 120 and the through hole 111 .

[0057] In this embodiment, PPS (a thermoplastic engineering plastic containing phenylthio groups on the main chain of the molecule, belonging to the polyether plastic) rubber is filled between the through hole 111 and the vertical rod of the pole 120 through the injection molding process, thereby sealing the gap between the pole 120 and the light cover 110, eliminating the sealing ring structure between the pole 120 and the light cover 110, reducing material costs, and at the same time, reducing the manual assembly process of the sealing ring and reducing labor costs. The sealing layer 130 is injection molded by the PPS injection molding process, which increases the insulation performance of the cover and reduces the insulation performance failure caused by dust adhering to the sealing ring.

[0058] like Figure 1 As shown, in one embodiment, it also includes:

[0059] The explosion-proof valve 150 is disposed on the optical cover plate 110 , and the explosion-proof valve 150 is located between the two through holes 111 .

[0060] In this embodiment, after the light cover plate 110 is subjected to T-treatment, the explosion-proof valve 150 is welded to the light cover plate 110 , and the light cover plate 110 can be subjected to pressure relief treatment when the light cover plate 110 is installed.

[0061] like Figure 1 As shown, in one embodiment,

[0062] The explosion-proof valve 150 has an explosion-proof membrane 151 .

[0063] In this embodiment, after the sealing layer 130 is injection molded, the explosion-proof valve 150 is pasted with a film, and the explosion-proof film 151 is pasted on the explosion-proof valve 150. The explosion-proof film 151 is usually calculated based on the operating pressure of the dust removal system and the content of combustible substances, and then the material and thickness are selected. The normal operation of the system must not be affected by improper selection.

[0064] like Figure 1-Figure 2 As shown, in one embodiment,

[0065] The optical cover 110 has screw holes 160 .

[0066] In this embodiment, the screw holes 160 on the optical cover plate 110 facilitate installation of the optical cover plate 110 .

[0067] In one embodiment,

[0068] The side edge of the optical cover plate 110 is in a stepped shape.

[0069] like Figure 1-Figure 2As shown, in this embodiment, the side edge of the light cover plate 110 is stepped, which facilitates sealing of the side edge of the light cover plate 110 when the light cover plate 110 is installed.
