Embodiment
Clearer for technical problem, technological scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As Fig. 1-shown in Figure 4, according to a kind of mode of execution of the present utility model, comprise spool 1, elastic water-proof spare 2 and circlip 3, the described inner wall surface that goes out spool is the conical surface 11, and is provided with a draw-in groove 12 at the big end of conical surface of inboard wall 11; Described elastic water-proof spare 2 is provided with a wire outlet hole, elastic water-proof spare 2 outer surfaces are and the described outlet inner tube wall conical surface 11 corresponding conical surfaces 21, this conical surface matches with the conical surface of inboard wall that goes out spool, and elastic water-proof spare 2 is being the R-joining 22 that an angle offers its outlet hole wall of cut-out with its axial direction, R-joining 22 connects wire outlet hole from the conical surface 21, cable can be put in the wire outlet hole by R-joining 22, describedly go out spool 1 and described elastic water-proof spare 2 cone match, described circlip 3 snaps in draw-in groove 12, and be against on the elastic water-proof spare 2, described elastic water-proof spare 2 closely is fixed on out in the spool 1.
Preferably, described angle is the 30-45 degree.If angle is too small, by the small dislocation by R-joining 22, wire outlet hole diameter variation amount is just very little, can't adapt to the variation of cable diameter; If angle is excessive, after elastic water-proof spare 2 packed spool 1 into, the dislocation that R-joining 22 produces was just bigger, may reduce waterproofing effect.
Preferably, the seam of described R-joining 22 is wide is no more than 0.5 millimeter.If stitch wide excessively, the diameter of wire outlet hole diminishes when causing using, and does not meet original specification requirement, causes the waste of material, perhaps directly causes elastic water-proof spare 2 unavailable.The present embodiment centre joint is wide to be 0.5 millimeter.
Preferably, described R-joining 22 is straight line groove parts, straight line type R-joining 22 can make the level and smooth slip of outlet hole wall, thereby form dislocation, like this by the small dislocation of R-joining 22, can realize autoregulation when the cable diameter size changes within the specific limits, thereby improve because the waterproof sealing effect during the cable diameter size variation.
Preferably, described draw-in groove 12 is the circular groove that circumferentially is provided with along the outlet inner tube wall, and the fixing of circlip also is convenient in the draw-in groove 12 that is provided with like this processing and assembling easily.
Preferably, the number of described circlip 3 is 2-3, when using 3 pairs of elastic water-proof spares 2 of a circlip to position, when spool 1, elastic water-proof spare 2 and circlip 3 occurring and can not make elastic water-proof spare 2 be pressed on out situation in the spool 1, increase 1-2 circlip 3, promptly be arranged side by side 2-3 back-up ring, above-mentioned three is closely cooperated.
In order to make waterproofing effect better, also be convenient to the installation of cable, described elastic water-proof spare 2 is preferably rubber sleeve.Described R-joining runs through the two ends of rubber sleeve.
Introduce use assembly process of the present utility model below:
When cable one first end has the bigger plug of diameter, perhaps when elastic water-proof spare 2 wire outlet holes satisfy its size requirement, perhaps when the diameter of cable is bigger slightly than wire outlet hole, after can pulling open by the R-joining 22 of elastic water-proof spare 2 one sides cable is put into elastic water-proof spare 2, and directly pass the wire outlet hole of elastic water-proof spare 2 without plug.
Again elastic water-proof spare 2 is filled in out in the spool 1, this moment, the conical surface 21 of elastic water-proof spare 2 can be automatically to being a tight fit in together with the conical surface of inboard wall 11 that goes out spool 1, and elastic water-proof spare 2 crack that what take is R-joining, like this by the small dislocation of R-joining 22, can realize autoregulation when the cable size changes within the specific limits, thereby improve because the waterproof sealing effect during the cable size variation.
At last circlip 3 is snapped in out in the draw-in groove 12 of spool 1, realization is to the location once more of elastic water-proof spare 2, if at this moment elastic water-proof spare 2 and circlip 3 defective tightness, add another one circlip 3 up to elastic water-proof spare 2, go out till spool 1 and circlip 3 threes closely cooperate.
Or go out spool 1 and can adopt the welding type thread type to be connected, all do not influence waterproof sealing effect of the present utility model with the casing joint.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
