Embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1 and Figure 2, in embodiment of the present utility model, cable sealing device comprises support 1, seal 2 and seal cover 3.Seal 2 comprises seal 21, is provided with the boss 23 of a hollow structure on the seal 21 at least, and the end face away from seal 21 on the boss 23 is provided with through wires hole 231, and the other end is provided with endoporus 232.Tight in order to seal, the diameter of through wires hole 231 is less than the diameter of cable, when cable passes through wires hole 231 since through wires hole 231 be wrapped in cable around, make cable and seal 2 to be connected sealing property better.Support 1 is installed on the seal 21, and opposed with the position of boss 23, and support 1 adopts metal plate structure, and it is more firm that cable sealing device is installed in the regulator cubicle.Seal cover 3 can be installed in the through wires hole 231, to play the effect of sealing through wires hole 231, in use can remove and install separately.Support 1 is provided with through hole 13, and through hole 13 is corresponding with the position of endoporus 232, is convenient to cable during use and passes.
For cable sealing device is fixedly mounted on the regulator cubicle, in the embodiment of the utility model cable sealing device, support 1 is provided with support connecting hole 12.Correspondingly, seal 2 and support connecting hole 12 corresponding positions are provided with seal connecting hole 22, and cable sealing device adopts threaded connector to pass seal connecting hole 22 and support connecting hole 12 makes it be connected the place that needs to pass in and out cable in the regulator cubicle.In other embodiment of the utility model cable sealing device, cable sealing device can also directly be bonded in the place that needs to pass in and out cable in the regulator cubicle by glue, has save the structure of support connecting hole 12 and seal connecting hole 22.
In an embodiment of the utility model cable sealing device, seal 21 adopts rectangular structure, its top is provided with two boss 23, boss 23 adopts conical structure, and be evenly distributed on the seal 21, the diameter of endoporus 232 can lead cable easily and enters in the through wires hole 231 greater than the diameter of cable.Accordingly, support 1 also adopts rectangular structure, and it is provided with two through holes 13 identical with the diameter of endoporus 232.Can also be provided with a plurality of boss 23 on the seal 21, correspondingly support 1 is provided with a plurality of through holes 13 that diameter is identical and quantity equates with endoporus 232.
Four corner positions of support 1 are provided with support connecting hole 12, and correspondingly, seal 2 and support connecting hole 12 corresponding positions are provided with four seal connecting holes 22.Support connecting hole 12 is distributed in four corner positions of support 1, when cable sealing device be installed in need in the regulator cubicle to pass in and out cable local time, its connective stability is higher.
Seal 21 is provided with heavy stand 211, and support 1 is installed in the heavy stand 211, strengthens the sealing property of seal 2 and support 1.The degree of depth of heavy stand 211 equates that with the thickness of support 1 seal 2 adopts the rubber material to make, and can support 1 bag be attached to the inside of seal 2 by plastic cement technology.
Seal cover 3 comprises closure body 31, screws portion 32 and crawl section 33.Screw portion 32 and crawl section 33 is arranged at respectively on the closure body 31.Seal cover 3 is installed in the through wires hole 231 by the portion of screwing 32.Above seal cover 3, be provided with crawl section 33, more convenient to operate when making the user be tightened in seal cover 3 in the through wires hole 231.In the present embodiment, closure body 31 adopts the structure of hollow circular cylinders, make seal cover 3 and seal 2 to be connected sealing property better, reduced the cost of cable sealing device simultaneously.
In above-described embodiment of the utility model cable sealing device, the metallic plate that support 1 adopts non-magnet_conductible material to make.Seal cover 3 adopts soft insulating material to make, and it has, and extensibility is strong, the toughness advantages of higher.
When specifically using the utility model cable sealing device, adopt threaded connector cable sealing device to be installed in the place that needs to pass in and out cable in the regulator cubicle, when needs pass cable from regulator cubicle, only need turn on seal cover 3, cable passed from through wires hole 231 get final product, because the diameter of through wires hole 231 is less than the diameter of cable, its sealing property is better.Simultaneously, in the threading process, avoided tool using that seal 2 is poked, and produced the not tight problem of sealing that line mouth place plastic cement anomalous fracture brings.The quantity of boss 23 can design according to user's needs in the seal 2, to be applicable to how dissimilar regulator cubicles.The size of through wires hole 231 can also design according to the diameter of using cable, with the line demand of crossing of the cable that satisfies different model.Cable sealing device adopts the structure of support 1, seal 2 and seal cover 3, and it is simple in structure, good seal performance, and with low cost.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
