Abstract
The utility model discloses a drawing head structure which includes a cup-shaped outer casing pipe; The bottom of the outer casing pipe is provided with at least one through hole; the through hole is internally penetrated by a conductor casing pipe; the front end of the conductor casing pipe protrudes outside the outer bottom of the outer casing pipe and is screwed with a screw nut; the middle part of the conductor casing pipe is provided with a flange leaning against the inner bottom of the outer casing pipe, wherein the diameter of the flange is larger than that of the through hole; and the rear end of the conductor casing pipe is provided with a hollow pipe sleeve for sleeving cable core conductor ends. Compared with a conventional drawing head structure, in the utility model, the cable core is sheathed by the conductor casing pipe and is fixed with the outer casing pipe through the screw nut, so that the cable is guaranteed not to fall off during the dragging process; and the outer casing pipe wraps around the outer sheath of the cable head, so that the outer sheath of the cable is prevented from being broken in the dragging process and further from damaging the internal section of the cable.
Description
Technical field
When the utility model relates to a kind of cabling for clamping, protect the drawing head structure of cable end.
Background technology
Present drawing head structure used when cabling is all very simple,, water level lower, dry occasion better to execution conditions can meet the demands completely, to execution conditions comparatively severe occasion time, common drawing head structure can not meet dilatory requirement of strength, often occurs that cable end comes off, cable jacket is drawn bad situation midway.
Utility model content
The utility model technical issues that need to address are that the drawing head structure that a kind of tensile strength is higher, cable end is had to protective effect is provided.
The technical solution of the utility model is: a kind of drawing head structure, comprise cup-shaped outer tube, at the bottom of outer tube pipe, have at least one through hole, in described through hole, be equipped with conductor casing, at the bottom of described conductor casing front end protrudes from outer tube outer tube and be screwed with nut, described conductor casing middle part is provided with flange that diameter is greater than described through hole withstand outer tube inner tube at the bottom of, described conductor casing rear end is provided with hollow pipe box and entangles cable core conductor termination.
As preferably, the hollow pipe box diameter in the rear end of described outer tube is greater than cable maximum gauge.
As preferably, at the bottom of described outer tube inner tube and between the flange at conductor casing middle part, be provided with conductor pad.
As preferably, at the bottom of described outer tube outer tube, be an outstanding round platform, round platform periphery has screw thread.
As preferably, be provided with spring washer and plain washer between at the bottom of described nut and outer tube outer tube.
As preferably, described conductor casing and cable core conductor compress and form a fixed connection with pressing tongs.
As preferably, after described cable core conductor is connected with conductor casing, overlaps and have " O " type elastic tape, " O " type elastic tape expands and pushes the hollow pipe box formation in the rear end confined space of outer tube.
Compare with drawing head structure in the past, cable core is socketed afterwards with conductor casing the utility model and outer tube is fixed with nut, with this, guaranteed that cable can not come off in dilatory process, and outer tube is lived the outer sheath encircles of cable head, prevent that cable sheath from being pulled open in dilatory process, damages cable inside.
Accompanying drawing explanation
Accompanying drawing 1 is the cross-sectional schematic of the utility model drawing head structure.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, the drawing head structure of the present embodiment, comprise cup-shaped outer tube 9, the 9 pipe ends of outer tube, have at least one through hole, in described through hole, wear cylindrical conductor sleeve pipe 7, conductor casing 7 middle parts are provided with flange that diameter is greater than described through hole withstand outer tube 9 inner tubes at the bottom of, at the bottom of conductor casing 7 one end protrude from outer tube 9 outer tubes and be screwed with nut 3, conductor casing 7 other ends are hollow pipe box, entangle cable core conductor 8, the described outer tube 9 hollow pipe box diameters in rear end are greater than cable maximum gauge, at the bottom of described outer tube 9 inner tubes and between the multidiameter at conductor casing 7 middle parts, be provided with conductor pad 6, it at the bottom of described outer tube 9 outer tubes, is an outstanding round platform, round platform periphery has screw thread, between at the bottom of nut 3 and outer tube 9 outer tubes, be provided with spring washer 4 and plain washer 5.
When installing and using, first cable end is separated to cable core conductor 8, every cable core conductor 8 is put to conductor casing 7, then by the nut 3 of finally screwing in the through hole of the threaded one end insertion of conductor casing 7 outer tube 9.As preferably, at the bottom of the inner tube of outer tube 9 and between conductor casing 7, conductor pad 6 can be set, pad is established plain washer 5 and spring washer 4 between at the bottom of the outer tube of nut 3 and outer tube 9, and cable jacket 10 is made encapsulation process with outer tube 9 joining places, can obtain preferably fire resistance characteristic.As preferably, outer tube 9 can be comprised of two independent parts, one is the round platform with through hole, another is the pipe box of nozzle diameter and round platform diameter coupling, both weld use, when integral installation, after can first cable core conductor 8 and round platform having been assembled, weld with pipe box more like this, simplified whole installation process.
Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure those skilled in the art that allow to change can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
