The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Example 1
In this embodiment, a clamp structure of a cable connector is specifically provided to achieve that the cable 7 of a freight train has a good waterproof function in transmission, and needs to be used in cooperation with a corrugated pipe and an aviation plug, and the aviation plug is an electromechanical element connected with an electrical line and widely applied to power supply transmission, and is not described herein again; this bellows 1 adopts stainless steel material and carries out whole processing through the mould and make, compares ordinary coiling formula iron sheet protection hose, and intensity is higher, and the reliability is better.
As shown in fig. 1 and 2, the clamp structure includes two clamp shells 8, two the clamp shells 8 splice each other to form the ring structure, and the inner ring side of this ring structure is established to annular notch and this annular notch and the crest structure phase-match of bellows 1, at the actual installation in-process, with two the clamp shells 8 are nested respectively in the crest structure of bellows 1, and two the tip of clamp shells 8 contacts each other in order to splice into the ring structure, and this ring structure and locking connect 2 between interact be used for transmitting the locking force of locking joint 2 for the terminal surface of bellows 1. Adopt two clamp casings 8 to constitute the preferred scheme of this embodiment only, still can set up to 3 clamp casings and splice each other in order to form the clamp structure according to actual conditions.
In order to ensure that the hoop shell 8 can be quickly embedded in the wave crest structure of the corrugated pipe 1, the edge of the port of the annular notch can be provided with an outward-expanding structure 10, and the outward-expanding structure 10 is more beneficial to quickly embedding the hoop shell 8 in the wave crest structure of the corrugated pipe 1; because when carrying out cable connector fitting, need earlier with 8 nestings of clamp casing on the crest structure of bellows 1, the clamp structure suit that forms of clamp casing 8 again is in locking joint 2's inside, for preventing when installation locking joint 2 or dismantlement locking joint 2, single clamp casing 8 self easily takes place to drop, in this embodiment, the adoption will the medial surface of annular groove is established to coarse friction surface to increase the frictional force size that exists between the crest structure of clamp casing 8 and bellows 1, play the effect of supplementary chucking.
Example 2
As shown in fig. 3 and 4, on the basis of embodiment 1, in order to reduce the processing cost of the clamp housing 8 and the problem of later-stage adaptability, two clamp housings 8 are set to be the same in size and shape, that is, the half part of the circular ring-shaped structure, and meanwhile, an elastic rubber pad matched with the two clamp housings is embedded in the clamp housing 8, so as to reduce the acting force of direct contact between the clamp housings 8 and the corrugated pipe 1, and prevent the wave crest structure of the corrugated pipe 1 from being damaged or damaged under the condition of direct stress.
In order to ensure that the two clamp shells 8 are not mutually dislocated when the clamp structure is pressed by the outside, the surface acting force of the seal ring 3 is more uniform by the clamp structure, one end of the clamp shell 8 is provided with a protruding male head 11, the inside of the other end is provided with a countersunk notch 12 matched with the male head 11, when the two clamp shells 8 are assembled, the male head 11 at one end of the upper clamp shell 8 is aligned with and inserted into the countersunk notch 12 at the other end of the lower clamp shell 8, the assembly is carried out in such a way to form the clamp structure, at the moment, the bordering end surfaces of the two clamp shells 8 are matched by the male head 11 and the countersunk notch 12, when the clamp structure is pushed at the later stage, the two clamp shells 8 cannot be mutually dislocated, so that the stress effect of the seal ring 3 under the pushing of the clamp structure is more uniform, and the sealing effect of the sealing ring 3 is better.
Example 3
As shown in fig. 5 and fig. 6, on the basis of embodiment 1 or embodiment 2, in order to further ensure that the two band housings 8 form a band structure after assembly, in order to prevent the two band housings 8 forming the band structure from falling off easily when the locking joint 2 is assembled or disassembled, and meanwhile, after the band structure is disassembled, the band structure is still maintained in an assembled state, and a situation that a certain single band housing 8 is lost does not occur, the specific structural design is as follows:
the one end side of clamp casing 8 extends and has seted up card hole 5 on elastic sheet 9 and the elastic sheet 9, and this elastic sheet 9 is integrated into one piece on clamp casing 8, is equipped with dop 4 that corresponds the matching with card hole 5 on the side of the other end, and elastic sheet 9 card hole 5 of its self can be gone into to dop 4 under the elastic action of self. In practical application, the installation process is as follows:
the upper clamp shell 8 and the lower clamp shell 8 are aligned relatively, the upper clamp shell 8 and the lower clamp shell 8 are pressed simultaneously, at the moment, the elastic sheet 9 on one side is aligned with the clamping head 4 of the other clamp shell 8 on the side and clamped in under the elastic action to form a clamp structure, at the moment, the bordering end faces of the two clamp shells 8 are locked under the mutual matching action of the elastic sheet 9 and the clamping head 4, and when the clamp structure is installed in the previous period, the two clamp shells 8 forming the clamp structure are not easy to fall off; after the hoop structure is disassembled at the later stage, the hoop structure can still be maintained in a combined state, the hoop structure is easy to store, and the falling of a certain single hoop shell 8 cannot occur.
Example 4
As shown in fig. 7, the clamp structure provided in embodiment 1, embodiment 2 or embodiment 3 is applied to practice, and further includes a locking joint 2 sleeved outside the corrugated pipe 1, the locking joint 2 is in threaded connection with the end of the aircraft plug, and the end of the aircraft plug is provided with a sealing ring 3, and the sealing ring 3 is used for forming a sealing connection between the corrugated pipe 1 and the end of the aircraft plug; with the clamp structure assembly on bellows 1, one side of this clamp structure support tightly in locking joint 2's inside and the opposite side through this clamp structure orders about bellows 1's tip with sealing washer 3 offsets tightly, because sealing washer 3 carries out good sealing between bellows 1's tip and aviation plug's the tip, forms good shutoff effect to the fit clearance between the two to prevent that outside moisture from entering into to inside, with the relatively poor problem of leakproofness between the tip of solving bellows 1 and aviation plug.
The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all the technical solutions falling within the scope of the present invention, are within the protection scope of the present invention.
