Problems solved by technology
[0004] In the past, when the wires were passed through the traditional sealing member 100, a gap would often be created between the sealing member 100 and the wires due to the pulling of the wires, resulting in the sealing failure of the sealing member 100
In addition, the hole diameter of the conventional seal 100 can only be applied to the wire of a certain wire diameter
If the wire diameter of the electric wire is much larger than the aperture of the sealing member 100, it is also possible that the electric wire cannot pass through the hole 11 of the sealing member 100; or, if the wire diameter of the electric wire is too close to the aperture of the sealing member 100, it will cause insufficient tightness and seal poor results
Therefore, the sealing member 100 with various aperture styles can only be developed for wire diameters of different sizes.

Embodiment Construction
[0032] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0033] See figure 2 and image 3 , Are respectively a structural perspective view and a structural cross-sectional view of a seal according to an embodiment of the present invention. Such as figure 2 and image 3 As shown, the sealing element 200 of an embodiment of the present invention is a circular (or square) member with elasticity, such as a circular (or square) elastic element made of rubber material, which is used for waterproof sealing of the wire 300. The seal 200 includes a body 20. A recessed area 21 is formed in the middle of the main body 20, and a sealing portion 23 is provide...

The present invention relates to a sealing element which is the component having elasticity and is used for waterproof sealing of an electric wire. The sealing element comprises a body and a concave area, wherein the concave area is formed in the middle of the body and comprises a sealing part; a hole is formed in the center of the sealing part; a plurality of rings of convex ribs are sequentiallyarranged at the periphery of the hole; the wire diameter of the electric wire is larger than the aperture of the hole; and when the electric wire enters the interior of the sealing element from the concave area, the electric wire penetrates through the sealing part by pushing the hole of the sealing part to open the hole, and the sealing part deforms due to the pushing of the electric wire, so that at least one circle of the convex rib are tightly matched on the electric wire to achieve the waterproof and sealing effects, and the waterproof and sealing effects of the electric wire with various wire diameter sizes are achieved only by the single type of sealing element.
Description
Technical field [0001] The invention relates to a sealing element, in particular to a sealing element used for waterproof sealing of electric wires. Background technique [0002] In order to prevent liquid (for example, water) from leaking into the product along the wire, the electronic product usually puts a seal at the interface of the connecting wire, and the wire enters the electronic product through the seal. [0003] See figure 1 , Is a three-dimensional view of the traditional seal structure. As shown in 1, the conventional seal 100 is an annular rubber ring with a hole 11 in the inner ring. The wire passes through the hole 11 in the inner ring of the sealing member 100 to enter the electronic product. Moreover, the wire diameter must be larger than the aperture of the hole 11 of the sealing member 100, so that when the wire passes through the hole 11 of the sealing member 100, the wire body of the wire can abut against the inner ring of the sealing member 100 and interact...
