Description

Technical Field

[0001] This utility model relates to the field of silicone sealing technology, specifically a waterproof and dustproof silicone sealing device for a flexible circuit board of vehicle radar. Background Technology

[0002] Silicone sealant is a sealing material made primarily of silicone rubber, combined with vulcanizing agents, reinforcing agents, and other additives. It possesses excellent resistance to high and low temperatures, allowing use in temperatures ranging from -65°C to 250°C. It also exhibits excellent resistance to weathering and ozone, as well as superior electrical insulation properties. However, it has poor mechanical strength and is not resistant to various media.

[0003] Existing patent: CN220910460U, discloses a silicone sealing ring, belonging to the field of sealing ring technology. The silicone sealing ring includes a workpiece and a silicone sealing ring body. An interlocking groove is provided at the joint between the workpiece and the silicone sealing ring body. A silicone sheet is provided on the outer surface of the silicone sealing ring body.

[0004] The aforementioned patents or existing silicone sealing devices have the following problems:

[0005] Existing silicone sealing devices have a simple structure and poor support, resulting in a mediocre sealing effect. Utility Model Content

[0006] The purpose of this invention is to provide a waterproof and dustproof silicone sealing device for a flexible circuit board of vehicle radar, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof and dustproof silicone sealing device for a flexible circuit board of vehicle radar, comprising a strip body, wherein the strip body is composed of a base adhesive and a top adhesive, and the top adhesive is provided at the upper end of the base adhesive.

[0008] Preferably, there are two top adhesives, and the tops of the two top adhesives are on the same horizontal plane.

[0009] Preferably, both top adhesives are inclined and positioned on top of the base adhesive.

[0010] Preferably, a first notch is formed between the two top adhesives, and the first notch is U-shaped.

[0011] Preferably, a second notch is formed between the top adhesive and the bottom adhesive on the right end, and the second notch is "C" shaped.

[0012] Preferably, the right end of the base adhesive extends outward, and the corner of the base adhesive is at a right angle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the base adhesive is placed, it will press against the right-angled corner of the base adhesive under pressure, and then one end will press into the second recess, which is shaped like a "C". The second recess has the function of positioning and limiting the installation, and also has the beneficial effect of high sealing performance. At the same time, it will be pressed into the first recess, which is shaped like a "U". The first recess is shaped like a "U" and can be used for edge sealing. It also has reliable support capacity, so as to achieve reliable support performance and high sealing performance. It has better waterproof and dustproof capabilities for the installation of vehicle radar flexible circuit boards. Attached Figure Description

[0017] In the diagram: adhesive strip body-1, bottom adhesive-11, top adhesive-12, first notch-13, second notch-14. Detailed Implementation

[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0019] Please see Figure 1 and Figure 2 This utility model provides a waterproof and dustproof silicone sealing device for a flexible circuit board of vehicle radar, including a strip body 1. The strip body 1 is composed of a base adhesive 11 and a top adhesive 12. Two top adhesives 12 are provided, both integrally formed on the top surface of the base adhesive 11, and both top adhesives 12 are inclined and the top surfaces of the two top adhesives 12 are on the same horizontal plane.

[0020] In this utility model, a first notch 13 is formed between the two top adhesives 12. The first notch 13 is U-shaped. A second notch 14 is formed between the right top adhesive 12 and the bottom adhesive 11. The second notch 14 is C-shaped. The right end of the bottom adhesive 11 extends outward, and the corner of the bottom adhesive 11 is right angled.

[0021] Specifically, the base adhesive 11 is placed, and when under pressure, it will be pressed against the right-angled corner of the base adhesive 11, and then one end will be pressed into the second recess 14, which is "C" shaped. The second recess 14 has the function of positioning and limiting the installation, and at the same time, it has the beneficial effect of high sealing performance. It will also be pressed into the first recess 13, which is "U" shaped. The first recess 13 is "U" shaped and can be used for edge sealing, and it also has reliable support capabilities, so as to achieve reliable support performance and high sealing performance, and has better waterproof and dustproof capabilities for the installation of vehicle radar flexible circuit boards.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
