When the first end or the second end passes through the wire passing hole, certain external force assistance is needed to overcome the friction force in the threading process.

As a preferred embodiment, as shown in fig. 1 to 3, in this embodiment, the sealing element includes a body 10, the body 10 is formed by surrounding a side wall, the body 10 is a cylindrical structure with a circular section, and the two axial ends of the body 10 are a first end 11 and a second end 12 respectively. The middle space that the lateral wall encloses and closes forms line hole 20, and the both joint ends that the lateral wall encloses the combination department that closes are detachable structure, and both joint ends are equipped with lock structure 30 promptly, and when lock structure 30 lock, body 10 forms complete cylinder structure, and when lock structure 30 opened, body 10 formed the structure that has the breach.

referring to fig. 3, in some embodiments, the engaging structure 30 may include a locking groove 31 formed on one of the two engaging ends of the body 10 and a locking protrusion 32 formed on the other of the two engaging ends and engaged with the locking groove. For the assembly of the body 10 and the flat cable, the body 10 can be made of elastic material, such as rubber, when the fastening structure 30 is opened, the body 10 is elastically deformed by external force, so that the gap of the body 10 is enlarged, the flat cable can be assembled in the cable passing hole 20 through the gap, the flat cable can be conveniently installed in the cable passing hole 20, and after the flat cable is installed, the flat cable is fixed and sealed through the fastening structure 30. It should be noted that, in the present embodiment, the side wall of the body 10 is provided with the notch that can be closed by the fastening structure 30, so that on one hand, various ways are provided for assembling the flat cable and the sealing member, for example, during assembling, the flat cable and the electrical component may be welded first, and then the flat cable is mounted later through the notch. On the other hand, when the flat cable is assembled, the flat cable does not need to be connected to the other end from one end of the wire passing hole in a penetrating mode, the flat cable can be assembled from any position of the flat cable, the assembling efficiency is greatly improved, and the assembling time is saved. This is not possible with a one-piece seal.

In some embodiments, to improve the fixing effect and the sealing performance of the fastening structure 30, the engaging groove 31 and the buckle 32 are configured as a multi-stage stepped sealing structure, for example, in this embodiment, the two engaging ends of the body 10 are configured as complementary stepped structures, and on the combining end surfaces of the two stepped structures, a plurality of sets of corresponding protrusion and groove structures are formed, and when the protrusions and the grooves are engaged, the fastening structure 30 completes the fastening.

In this embodiment, a plurality of first elastic surrounding ribs 21 extending toward the middle of the wire passing hole 20 are disposed on the circumferential wall of the wire passing hole 20, the first elastic surrounding ribs 21 surround the circumferential wall of the wire passing hole 20 for a circumference, and the plurality of first elastic surrounding ribs 21 are sequentially disposed on the circumferential wall of the wire passing hole 20 at intervals along the circumferential direction. The first elastic surrounding rib 21 protrudes towards the middle of the wire passing hole 20, so that when the flat cable is assembled, the inner space of the wire passing hole 20 is in interference fit with the flat cable, and the first elastic surrounding rib 21 generates elastic deformation under the action of extrusion force to seal and fix the flat cable. Taking the electric cooker cover as an example, the display flat cable of the general cover is distributed in a scattered manner, and when the display flat cable is matched with the wire passing hole 20, the first elastic surrounding rib 21 generates circumferential pressure on the flat cable, so that the flat cable is circumferentially compressed and sealed. Compared with the traditional pressing plate structure, the first elastic surrounding rib 21 has even pressure on the flat cable, avoids breaking the flat cable, simultaneously performs dead-angle-free sealing between the flat cable and the wall of the wire passing hole 20 under the elastic action, does not need secondary filling of sealing materials, and still can perform proper length adjustment on the flat cable after the first elastic surrounding rib 21 compresses the flat cable due to the elastic surrounding rib structure, does not need to be disassembled, and is convenient for adjustment in the installation process.

it should be noted that, in the present embodiment, the plurality of first elastic beads 21 are sequentially disposed at intervals in the axial direction of the wire passing hole 20, and in some alternative embodiments, the plurality of first elastic beads 21 may also be disposed in any other structure suitable for implementation. In an exemplary embodiment, the first elastic bead 21 may also be disposed spirally on the inner portion of the wire through hole 20, so as to form a multi-layer bead structure. The invention is not limited in this regard.

In this embodiment, a plurality of second elastic surrounding ribs 22 extending outward are disposed on the outer wall of the body 10, the second elastic surrounding ribs 22 surround the outer wall of the body for a circle, and the second elastic surrounding ribs 22 are spirally distributed on the outer wall of the body 10. The second elasticity encloses muscle 22 and is outstanding outside towards the body 10 outer wall to when body 10 and face lid via hole assembly, make body 10 outer wall and via hole form interference fit, second elasticity encloses muscle 20 and produces elastic deformation under the extrusion force effect, covers between the via hole to body 10 and face and seals and fix. Taking the electric cooker surface cover as an example, when the body 10 is assembled with the surface cover via hole, the body 10 can be screwed into the surface cover via hole along the spiral direction of the second elastic surrounding rib 22, and the spiral second elastic surrounding rib 22 forms a self-tapping structure, so that the body 10 can be conveniently installed. When the body 10 and the surface cover are assembled through the hole, the second elastic surrounding rib 22 is elastically deformed under the extrusion of the inner wall of the through hole, so that the dead-angle-free butt sealing is performed between the outer wall of the body 10 and the wall of the through hole. The second elastic surrounding rib 22 and the first elastic surrounding rib 21 jointly form two-stage sealing, so that effective sealing is formed between the body 10 and the via hole and between the flat cable and the wire passing hole 20, and the sealing effect is improved.

preferably, in some embodiments, as shown in fig. 1, at least one raised sealing rib 25 is provided on the outer wall of the body 10, the sealing rib 25 is disposed along the axial direction of the body, and the protruding diameter of the sealing rib 25 in the radial direction of the body 10 is smaller than the diameter of the second elastic surrounding rib 22 extending outwards.
