Description

Technical Field

[0001] This utility model relates to the field of gasket technology, and in particular to a foamed silicone gasket. Background Technology

[0002] Existing electronic devices generally include a housing for housing electronic components. This housing is typically composed of a first housing and a second housing detachably connected. To improve the waterproof performance of the housing, a foamed silicone gasket is usually placed between the first and second housings. Additionally, inside the electronic device, a foamed silicone gasket is also placed between two internal electronic components to insulate them.

[0003] For large, rectangular foamed silicone gaskets, one side needs to be coated with adhesive for bonding to the external housing or electronic components. To avoid difficulty in removing the gasket and to reduce the adhesion of the adhesive side, multiple spaced blind holes are typically made on the silicone-coated side of the gasket. However, in actual production, creating these blind holes requires high machining precision. Because the foamed silicone gasket is very thin, the hole depth is difficult to control. If the holes are too deep, perforation can occur; if the holes are too shallow, the required machining precision cannot be achieved. This necessitates multiple adjustments for each production run, resulting in high machining difficulty and low production efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a foamed silicone gasket that improves the structure of the gasket itself, thereby solving the problems of high processing difficulty and low production efficiency in the past.

[0005] To solve the above-mentioned technical problems, this utility model discloses a foamed silicone gasket, including a gasket body. The top surface of the gasket body extends upward to form an upper folded portion, and the bottom surface of the gasket body extends downward to form a lower folded portion. The left and right sides of the gasket body extend outward to form side folded portions. The upper folded portion, the lower folded portion, and the side folded portions are all provided with multiple through holes arranged at intervals. The length of the side folded portion plus the width of the folded portion and the width of the lower folded portion are equal to the width of the gasket body. In the assembled state, the upper folded portion, the lower folded portion, and each side folded portion are folded inward and adhered to the gasket body.

[0006] The upper folding part has a groove on its outer side, and the side folding part has a locking protrusion at its end facing the upper folding part, which is inserted into the groove.

[0007] The end of the side fold facing the upper fold is coated with adhesive.

[0008] A first connecting portion is formed between the gasket body and the upper folded portion.

[0009] The width of the first connecting part is equal to twice the thickness of the gasket body.

[0010] A second connecting portion is formed between the gasket body and the lower folded portion.

[0011] The width of the second connection part is equal to twice the thickness of the gasket body.

[0012] A third connecting part is formed between the gasket body and the side fold.

[0013] The width of the third connection part is twice the thickness of the gasket body.

[0014] The upper fold, lower fold, and each side fold are all attached to the gasket body with adhesive.

[0015] Compared with the prior art, the present invention has the following beneficial effects: by setting an upper folding part, a lower folding part and a side folding part, and opening multiple through holes in the upper folding part, the lower folding part and the side folding part are folded inward and adhered to the gasket body, so that the multiple through holes are transformed into blind holes, reducing the processing precision of the gasket, saving debugging time, and thus improving production efficiency. It is especially suitable for thin foamed silicone gaskets. Attached Figure Description

[0023] This utility model discloses a specific embodiment of a foamed silicone gasket, please see... Figure 1 and Figure 2 It includes a gasket body 1, which is made of foamed silicone material.

[0024] As an improvement, the top surface of the gasket body 1 extends upward to form an upper folded portion 11, the bottom surface of the gasket body 1 extends downward to form a lower folded portion 12, and the left and right sides of the gasket body 1 extend outward to form side folded portions 13. The upper folded portion 11, the lower folded portion 12, and the side folded portions 13 are all provided with multiple spaced through holes 14. In the assembled state, the upper folded portion 11, the lower folded portion 12, and each side folded portion 13 are folded inward and adhered to the gasket body 1. Specifically, the upper folded portion 11, the lower folded portion 12, and each side folded portion 13 are adhered to the gasket body 1 using adhesive.

[0025] This embodiment of a foamed silicone gasket, by providing an upper folded portion 11, a lower folded portion 12, and a side folded portion 13, provides a plurality of through holes 14, which are respectively provided in the upper folded portion 11, the lower folded portion 12, and the side folded portion 13. The upper folded portion 11, the lower folded portion 12, and the side folded portion 13 are folded inward and adhered to the gasket body 1, so that the plurality of through holes 14 are transformed into blind holes, which reduces the processing precision of the gasket, saves debugging time, and thus improves production efficiency. It is particularly suitable for foamed silicone gaskets with thinner thickness.

[0026] As a preferred embodiment, the length of the side fold 13 is ( Figure 2 The length a) plus the width of the fold 11 ( Figure 2 The length b) and the width of the lower fold 12 ( Figure 2 The length c) is equal to the width of the gasket body 1. Figure 2 The length d). This ensures that the joints of the upper fold 11, lower fold 12 and each side fold 13 are flush after folding, avoiding bulges or gaps.

[0027] To improve the connection strength between the upper folding part 11 and the side folding part 13, please see Figure 3 The upper folding portion 11 has a groove 21 on its outer side, and the side folding portion 13 has a locking protrusion 22 at its end facing the upper folding portion 11. In the folded state, the locking protrusion 22 is inserted into the groove 21, thereby preventing the corner from warping. Specifically, the end of the side folding portion 13 facing the upper folding portion 11 is coated with adhesive, and the adhesive can further enhance the connection strength between the locking protrusion 22 and the groove 21.

[0028] In this embodiment, a first connecting portion is formed between the gasket body 1 and the upper folding portion 11. Preferably, the width of the first connecting portion is twice the thickness of the gasket body 1. A second connecting portion is formed between the gasket body 1 and the lower folding portion 12, and the width of the second connecting portion is twice the thickness of the gasket body 1. A third connecting portion is formed between the gasket body 1 and the side folding portion 13, and the width of the third connecting portion is twice the thickness of the gasket body 1. By providing the first, second, and third connecting portions, the necessary allowance for folding is provided, avoiding problems such as deformation or shape defects of the gasket as a whole.
