The core of the utility model is to provide a sealing structure, it can effectively improve the sealed effect of the bucket that packs, and simple structure, convenient to use of this device can use widely.

Please refer to fig. 8 to fig. 15.

This specific embodiment provides a seal structure, includes: cable, main part 1, inlay and locate the packing bucket 2 of main part 1 and be used for the sealing member 3 of shutoff packing bucket 2, packing bucket 2 is equipped with the passageway 5 that is used for passing the cable, and the tip of packing bucket 2 is located to sealing member 3, and sealing member 3 is equipped with through-hole 4 that is used for fixed cable, and through-hole 4 and passageway 5 link up.

The shape, structure, size, material and the like of the cable, the main body 1, the filling barrel 2 and the sealing element 3 can be determined according to actual conditions and actual requirements in the actual application process.

It should be noted that, when using the utility model provides a seal structure, at first, can pack into main part 1 with packing bucket 2 in, install sealing member 3 on the top of packing bucket 2 again, later, insert the cable again in through-hole 4 and passageway 5 to realize the fixed mounting operation of cable. Because the top at the bucket 2 that packs is equipped with sealing member 3, this sealing member 3 can effectively shutoff the top of bucket 2 that packs, avoids in subsequent liquid encapsulating process, and the liquid glue that appears takes place to leak the phenomenon in 2 terminal surfaces departments of bucket that packs, can effectively improve the sealed effect of bucket 2 that packs finally.

To sum up, the utility model provides a seal structure, it can effectively improve the sealed effect of bucket 2 that packs, and the simple structure of this device, convenient to use can use widely.

On the basis of the above embodiment, it is preferable that the cable and the sealing member 3 are in interference fit, and the sealing member 3 and the stuffing barrel 2 are detachably connected.

It should be noted that, because cable and sealing member 3 are interference fit, the size of the cable can be greater than 4 sizes of through-hole of sealing member 3 also, this makes sealing member 3 can effectively hold sealed cable tightly, avoids appearing in liquid encapsulating operation process, because of the sealing member 3 not enough to hold the power of cable tightly, and the phenomenon that liquid glue leaks to the cable appears, can guarantee finally the sealed effect and the aesthetic measure of product.

Preferably, the inner side of the bottom of the sealing member 3 is provided with a first protrusion 6, and the outer side of the top of the stuffing barrel 2 is provided with a first groove 7 for clamping the first protrusion 6. Therefore, the sealing member 3 can be sleeved on the top of the stuffing barrel 2 by using the first groove 7 and the first protrusion 6, so as to effectively seal the stuffing barrel 2.

Preferably, the first groove 7 and the first protrusion 6 are both annular structures, so that the periphery of the sealing member 3 is effectively fixed by the stuffing barrel 2.

Preferably, the first groove 7 and the first protrusion 6 are in interference fit, so that the clamping fixing effect of the sealing element 3 and the stuffing barrel 2 can be improved.

Preferably, the diameter of the through-hole 4 is 4mm to 8mm smaller than the diameter of the cable.

It should be noted that the minimum inner bore diameter of the sealing member 3 needs to be smaller than the maximum outer diameter of the cable to ensure that the sealing member 3 can effectively fix the cable, and the diameter of the through hole 4 of the sealing member 3 needs to be determined according to the size of a specific cable product. Preferably, the diameter of the through hole 4 is 4mm to 8mm smaller than the diameter of the cable, so that the cable can be effectively fixed by the sealing element 3, and the phenomenon that the through hole 4 is too small in size and damaged when the cable is inserted again can be avoided.

Of course, the difference in the dimensions of the through-hole 4 and the cable can be set to other values, but it is necessary to ensure that the sealing element 3 effectively seals and secures the cable without damaging it.

The shape, structure, size and the like of the first groove 7, the first protrusion 6 and the through hole 4 can be determined according to actual conditions and actual requirements in the actual application process.

On the basis of the above embodiment, it is preferable that the top of the sealing member 3 is provided with a film 8, the center of the film 8 is provided with a through hole 4, and the diameter size of the through hole 4 is smaller than that of the channel 5. Therefore, the part of the film 8, which is not provided with the through hole 4, can effectively seal the top of the packing bucket 2, so that the phenomenon that liquid glue leaks from the end face of the packing bucket 2 in the subsequent liquid glue filling process is avoided, and finally, the sealing effect of the packing bucket 2 can be effectively improved.

Preferably, the outer periphery of the sealing member 3 is provided with a ring-shaped second protrusion 9, and the inner periphery of the main body 1 is provided with a second groove 10 for clamping the second protrusion 9. Therefore, by using the second groove 10 and the second protrusion 9, the sealing effect between the sealing member 3 and the main body 1 can be ensured, and the effective sealing between the stuffing barrel 2 and the main body 1 can be ensured.

Preferably, the sealing element 3 is an elastic material element, so as to further improve the sealing effect of the sealing element 3 on the stuffing barrel 2 and also reduce the damage of parts in the press fitting operation process.

It should be noted that the sealing element 3 of the device can effectively seal and fix the cable, and the sealing element 3 can also effectively seal the top of the packing barrel 2, so as to avoid the leakage of the liquid packing and make the use of the product more stable.

It should be noted that the first protrusion 6 and the second protrusion 9, and the first groove 7 and the second groove 10 are mentioned in this document, wherein the first and the second are only for distinguishing the position difference and not for distinguishing the order.
