Abstract
The utility model relates to a two-part type lead sleeve closing molding electric cable junction box, which is characterized in that one end of a lead sleeve is extruded into a conical closing in a cold way to extend out a part pipe with changeable diameters. The part pipe with changeable diameters is arranged on a step region and the outside diameter of the part pipe with changeable diameters is a little bigger than that of a cable. The other end of the lead sleeve is jointed with a sheath shoulder, and the other end of the sheath shoulder is extruded into the conical closing in a cold way to extend out a part pipe with changeable diameters. The part pipe with changeable diameters is arranged on a step region, and the outside diameter of the part pipe with changeable diameters is a little bigger than that of the cable. Compared with the present closing which is fabricated on site and is beaten by hand, the utility model has the advantages of easily guaranteed welding quality, lightened labour on site, uniform thickness of the lead sleeve and good sealing performance. The utility model is suitable for the lead sleeve closing molding junction box of communication cables, power cables and long distance symmetric cables.
Description
The utility model belongs to the cable construction field, the cable-joint protector box that particularly a kind of lead sleeve closes up and is shaped.
At present, the lead-covered cable connector box generally adopts lead sleeve as encapsulant both at home and abroad, because this material is corrosion-resistant, humidity resistance is good, and the life-span is long, and price is low, is still using so far.Because how many differences of cable logarithm, used lead sleeve diameter is also different, and the diameter of lead sleeve is generally all big several times than the outside diameter of cable.Before soldering and sealing, earlier with the two ends of lead sleeve by hand gavel beat distortion, the two ends of lead sleeve are narrowed down to the diameter identical with the outside diameter of cable, be enclosed within on the cable, soldering and sealing then, sealing reach the good purpose of cable core insulation.For this reason, used lead sleeve is an one-part form, and manual the beaing in two ends is out of shape closing in, has only constriction, do not wrap up the extending part at cable socket place.So work progress, the soldering and sealing area is big, and the soldering and sealing time is long, and the difficult operation of workman is prone to heart yearn and bumps disconnectedly, roastingly sticks with paste adhesion, causes drawbacks such as swinging cross.
The purpose of this utility model is, design a kind of two segments combined lead sleeve, be processed in advance and have the stepped reducer pipe that wraps up cable socket, capable again assembly installation and soldering and sealing, to improve the soldering and sealing quality, reduce workman's execute-in-place time, prevent that the heart yearn joint from bumping the generation of disconnected and swinging cross, guarantee that each well section cable interface place realizes sealing, not intaking, do not advance moisture, the good purpose of insulation.
Two-part lead sleeve closing in shaping cable-joint protector box of the present utility model, form by lead sleeve, it is characterized in that, the tapered closing in of one end cold extrusion of lead sleeve, extend the reducer pipe of one section bigger slightly stepped portions than the outside diameter of cable, other end socket joint at lead sleeve connects a sheath shoulder, and the reducer pipe of one section bigger slightly than the outside diameter of cable stepped portions is extended in the tapered closing in of other end cold extrusion of sheath shoulder.
Using method of the present utility model is; Before cable joint, earlier lead sleeve and sheath shoulder are enclosed within respectively on two cable ends; The heart yearn joint that connects two cables; Again lead sleeve is withdrawn into the cable joint position, also moves the cable joint position to expanding the cover shoulder, and connect with the lead sleeve bell and spigot; The reducer pipe port and the bell and spigot of the stepped portions of two parcel outside diameters of cable of soldering and sealing are promptly finished the connector box operation.
The utility model has the advantages that: beat with used craft, field fabrication lead sleeve closing in position compares, because lead sleeve and sheath shoulder all have a transition shoulder reducer bigger slightly than the outside diameter of cable, the soldering and sealing area reduces, can shorten weld time, avoid cable core Yin Gaowen to bake paste, adhesion, swinging cross; Saving of work and time is saved welding material; Owing to adopt the two-part connector, during interface, heat that is produced and moisture can shed with the lead sleeve connecting portion from the sheath shoulder, reduce the excessive problem of accumulation of heat in the soldering and sealing procedural interface on soldering and sealing two end cables; Because the lead sleeve of two-part and sheath shoulder all are to adopt cold extrusion shaped making, thickness is even, and is non-wrinkle, stressed evenly, good seal performance has alleviated the labour intensity of artificial field operation.Be applicable to various different size local telephone communication cables, power cable, long distance symmetric cable, be particularly useful for the thin communication cable-end of lead layer and use.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the structure and the user mode figure of two-part lead sleeve closing in shaping cable-joint protector box.
As seen from the figure, two-part lead sleeve closing in shaping cable-joint protector box, form by lead sleeve, it is characterized in that, the reducer pipe 2 of one section bigger slightly than the outside diameter of cable stepped portions is extended in the tapered closing in of one end cold extrusion of lead sleeve 1, connects a sheath shoulder 3 at the other end socket joint of lead sleeve, the reducer pipe 4 of one section bigger slightly than the outside diameter of cable stepped portions is extended in the tapered closing in of other end cold extrusion of sheath shoulder.Among the figure, 5 is cable, and 6 are soldering and sealing.
