Description

Technical Field

[0001] This utility model relates to the field of electrical control product manufacturing technology, specifically a dustproof silicone plug for the production of friction welding electrical control products for new energy vehicles. Background Technology

[0002] With the development trend of the new energy vehicle industry, the quality requirements for electronic control products are also getting higher and higher. The cleanliness of the friction welding cooling water channels of electronic control products needs to meet the following requirements: metallic impurities <0.5mm, non-metallic impurities <1mm, and impurity content <50mg / 1000cm³. 2 The existing friction welding cooling channels of electrical control products are tubular in shape. During the friction welding and CNC processes, impurities can enter the friction welding cooling channels of electrical control products, affecting the cleanliness of the products and reducing their overall quality after production. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a dustproof silicone plug for the production of friction-welded electronic control products for new energy vehicles. This plug can block the cooling water channels of the friction welding process of the electronic control products, preventing impurities from entering the cooling water channels during the friction welding and CNC processes, thus ensuring the cleanliness of the electronic control products and improving their quality after production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dustproof silicone plug for the production of friction welding electronic control products for new energy vehicles includes a circular plunger and a plug cap fitted on the circular plunger. The top of the plug cap extends inward in a circumferential direction to form a retaining ring. The inner edge of the retaining ring is connected to the outer wall of the circular plunger, and the plug cap and the circular plunger together form an annular blocking space.

[0006] Furthermore, the central part of the circular plunger is a cylindrical plunger body, the top end of the cylindrical plunger body is a plunger head, and the bottom end is a plunger tail, and the retaining ring is connected to the cylindrical plunger body.

[0007] Furthermore, the outer diameter of the plug tail gradually decreases from top to bottom.

[0008] Furthermore, a cavity is provided at the bottom end of the plug tail, and the cavity extends axially from the bottom end of the plug tail into the cylindrical plug body.

[0009] Furthermore, the bottom end of the cap extends outward in a circumferential direction to form a conical cap brim.

[0010] Furthermore, the circular plunger, retaining ring, and plug cap are integrally formed.

[0011] Furthermore, the circular plunger, retaining ring, and plug cap are all made of silicone.

[0012] The beneficial effects of this utility model are:

[0013] In practical applications, before the friction welding and CNC processes, a circular plunger is inserted into the friction welding cooling channel of the electronic control product, with the plunger cap covering the outside of the cooling channel until the top of the cooling channel abuts against the retaining ring. This annular blocking space effectively blocks the cooling channel, preventing impurities from entering during the friction welding and CNC processes and ensuring the cleanliness of the electronic control product. This invention effectively blocks the friction welding cooling channel of the electronic control product, preventing impurities from entering during these processes, thus ensuring the cleanliness of the product and improving its overall quality after production.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a dustproof silicone plug for the production of friction welding electronic control products for new energy vehicles includes a circular plunger 1 and a plug cap 21 fitted on the circular plunger 1. The top of the plug cap 21 extends inward in a circumferential direction to form a retaining ring 22. The inner edge of the retaining ring 22 is connected to the outer wall of the circular plunger 1, and the plug cap 21 and the circular plunger 1 enclose an annular blocking space 3.

[0020] In use, before the friction welding and CNC processes, insert the circular plunger 1 into the friction welding cooling channel of the electronic control product, and place the plug cap 21 over the outside of the friction welding cooling channel until the top of the friction welding cooling channel abuts against the retaining ring 22. The annular blocking space 3 blocks the friction welding cooling channel of the electronic control product, thus preventing impurities from entering the friction welding cooling channel during the friction welding and CNC processes, ensuring the cleanliness of the electronic control product. This utility model can block the friction welding cooling channel of the electronic control product, preventing impurities from entering the friction welding and CNC processes, ensuring the cleanliness of the electronic control product, and also improving the quality of the electronic control product after production.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the central part of the circular plunger 1 is a cylindrical plunger body 11, the top end of the cylindrical plunger body 11 is a plunger head 12, and the bottom end is a plunger tail 13. The retaining ring 22 is connected to the cylindrical plunger body 11. In this embodiment, during use, the plunger tail 13 and the plunger head 12 are inserted into the friction welding cooling water channel of the electronic control product until the retaining ring 22 abuts against the top end of the friction welding cooling water channel of the electronic control product, thus sealing the top end of the friction welding cooling water channel of the electronic control product.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer diameter of the plug tail 13 gradually decreases from top to bottom; in this embodiment, when the outer diameter of the plug tail 13 gradually decreases from top to bottom, the plug tail 13 is easier to insert into the friction welding cooling water channel of the electronic control product.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cavity 14 is provided at the bottom end of the plug tail 13, and the cavity 14 extends axially from the bottom end of the plug tail 13 into the cylindrical plug body 11. In this embodiment, the cavity 14 can provide a certain deformation space for the plug tail 13 and the cylindrical plug body 11 inserted into the friction welding cooling water channel of the electronic control product, so that the cylindrical plug body 11 can block the friction welding cooling water channel of the electronic control product.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom end of the plug 21 extends outward in a circumferential direction to form a conical cap rim 23; in this embodiment, the conical cap rim 23 makes it easier for the plug 21 to be fitted onto the outside of the friction welding cooling water channel of the electronic control product.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the circular plunger 1, the retaining ring 22, and the plug cap 21 are integrally formed. In this embodiment, when the circular plunger 1, the retaining ring 22, and the plug cap 21 are integrally formed, the process is simple and the production cost is lower.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the circular plunger 1, the retaining ring 22, and the plug cap 21 are all made of silicone. In this embodiment, the circular plunger 1, the retaining ring 22, and the plug cap 21 made of silicone all have a certain degree of elasticity, resulting in better sealing and dust prevention.

[0027] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by this utility model.
