Description
The novel local cable joint that relates to of this reality, concrete is the open-close type local cable joint that a kind of machinery fixes.
Plastic telephone cable (being city communication cable) has been widely used in local telecommunication networking, cities and towns, for transmitting the professional signal of telecommunication such as phone, telegram and data.Because cable circumstance complication of living in, the involution of cable joint there is strict requirement, the statistics about fault in practical maintenance shows that the all-plastic cable fault more than 90% mainly betides cable joint involution place.Though all-plastic cable involution technology constantly obtains innovation and improves, except that cold joint formula involution method, mould pipe injection moulding involution method in addition, various hot joining formula involution methods such as heat-shrink tube involution method, these methods respectively have pluses and minuses, and the common issue with of existence is to reopen coincidence.
The purpose of this utility model provides a kind of brand-new local cable joint, overcomes the deficiencies in the prior art, can reopen involution, and cost saving as far as possible again.
Used technical scheme: open-close type local cable joint of the present utility model, form by fitting sleeve, tight lid, lock ring etc., it is characterized in that: fitting sleeve constitutes by left and right two that half-and-half separate along center line, with mechanical fixing mode cable end is clamped.
The best specific embodiment of present technique has following feature:
A. fitting sleeve, tight lid, lock ring respectively constitute by two that half-and-half separate along center line.
B. the internal layer of fitting sleeve is an aluminium, skin is plastics, its stage casing is that hollow half garden is tubular, its two ends are blank area, this joint is by becoming the stepped big axle journal that dwindles to the end, middle axle journal and thin neck cover constitute, center along thin neck cover and middle axle journal has break slot, the semicircle endoporus of thin neck cover adds behind the Rubber washer corresponding with the diameter of cable, and endoporus is made screw thread, on the excircle of big axle journal and middle axle journal, there is the spiral shell button to be used for equipped tight lid, described big, the inner periphery of middle axle journal is filled with Rubber washer, the center of this Rubber washer has the diameter of semicircle orifice and cable corresponding, and the plane of this Rubber washer is higher than the plane of fitting sleeve, convex-concave waveform microgroove is arranged on the plane of this Rubber washer, in that the groove that is made of hypotenuse and periphery is arranged on the tubular semi-circle plane in the stage casing of fitting sleeve and on the plane of the big axle journal in end, on a left side, when right two halves fitting sleeve is combined into full circle, the sealing joint strip of packing in this groove.At the end place of the groove of described fitting sleeve, one of left and right two fitting sleeves have location hole, and another part has the alignment pin of protrusion, is vasiform stage casing at fitting sleeve, and part is equipped with valve one of in left and right two.
C. tight lid is the semicircle cover that the stairstepping internal thread is arranged, the excircle screw thread of big axle journal in the end of its internal thread and fitting sleeve and middle axle journal matches, its small end has the back taper contraction edge, and this contraction edge inwall has annular groove, and the bulge loop at this groove and the lock ring conical horn mouth back side matches.Have two chimbs concordant with the branch boundary plane on tight lid cylindrical, on the plane of these two chimbs, one of left and right of a pair of tight lid has T shape raised line, and another part has the T connected in star.
D. there is the semi-circle tubular part of bellmouth in lock ring system, the excircle dimension of the thin neck cover in the end of its taper hole and fitting sleeve is corresponding, at the oriented horn mouth that turns up in the big end of its taper hole place, on this bell-mouthed back side bulge loop is arranged, there are two chimbs concordant at the cylindrical place of described taper hole with interface, on the plane of this two chimb, one of left and right of a pair of lock ring has T shape raised line, and another part has the T connected in star.
One of present technique embodiment is the stair-stepping big axle journal of one-tenth of the left and right end of fitting sleeve, middle axle journal and thin neck cover, and the one end is only headgear, adorns a branch cable, it is held in addition and is the difference headgear, adorns two branch cables.
The instrument that present technique is used for tight lid is made of interior ring and outer shroud handgrip, interior ring is two that half-and-half separate along center line, unidirectional ratchet is arranged on its cylindrical, middle part of circle respectively has two to projecting inward shifting block in it, and the spacing of this shifting block and height are corresponding with the size that tight lid makes up the chimb on its cylindrical of back.The outer shroud handgrip is a twin nuclei, along center line in two, and the both sides pillow block of ring in dicyclo blocks, hinged in end, unidirectional ratchet is equipped with in corner at an outer shroud handgrip and outer shroud, and this ratchet is subjected to the thrust of spring, and this spring-loaded is being connected on the spring base of handgrip.
The local cable joint that the utility model provides has following good effect:
