Description

Signal line cramping joint

The utility model belongs to the circuit part, particularly a kind of signal line cramping joint.

As shown in Figure 1, the signal wire of commonly using lies in to install in the nut 1 and is the intubate 2 of hollow column, and affixed length is greater than the clamp 3 of its length outside intubate 2.During winding, cable 4 is inserted cramping in the clamp 3, cable 4 is packed between intubate 2 and the clamp 3, but because the length of intubate 2 is shorter than clamp 3, so when cable 4 bendings, can make between cable 4 and the clamp 3 and produce the gap, cause aqueous vapor in clamp 3 is infiltrated in the gap, cause signal wire to reduce useful life, the reception quality descends.

The purpose of this utility model provides a kind of signal line cramping joint that improves signal wire useful life, guarantees the reception quality.

The utility model comprises nut, intubate and clamp; The nut inner bottom is provided with rank portion; Intubate one end is provided with the outer ring edge that can be equipped in nut rank portion; Clamp one end is provided with interior ring edge, and its other end forms the supporting section that extends clamp; Nut and clamp are sheathed on the intubate in regular turn to loosen, tighten cooperation respectively, and the supporting section of intubate extends clamp.

Wherein:

The intubate peripheral ring is established first ratchet ring that forms the salient point ring; Clamp and the intubate first ratchet ring salient point ring opposite position are provided with circular groove.

Be provided with second ratchet ring that forms the salient point ring between the supporting section of intubate and first ratchet ring; Clamp and the intubate second ratchet ring correspondence position are provided with and form the starting taper face that the awl point that is meshed with the second ratchet ring salient point ring encircles.

Because the utility model comprises nut, intubate and clamp; The nut inner bottom is provided with rank portion; Intubate one end is provided with the outer ring edge that can be equipped in nut rank portion; Clamp one end is provided with interior ring edge, and its other end forms the supporting section that extends clamp; Nut and clamp are sheathed on the intubate in regular turn to loosen, tighten cooperation respectively, and the supporting section of intubate extends clamp.During winding, cable is inserted clamp, and make in its core and being arranged in the intubate, its lead then passes nut by this; Make coniform cramping with the packing cable by instrument then, because of the supporting section of intubate extends outside the clamp, after cable is limited in the clamp by packing, by the supporting section of intubate cable inside is formed radial support power, can make the unlikely overflexing of cable, can effectively avoid and clamp between produce the gap, block aqueous vapor and enter to reach, not only improve signal wire useful life, and guarantee the reception quality, thereby reach the purpose of this utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As shown in Figure 2, the utility model comprises nut 10, intubate 20 and clamp 30.

Nut 10 is the hexagonal moulding, and its inner bottom is provided with rank portion 11.

Intubate 20 is the circular cylindrical shape body of hollow, and intubate 20 1 ends are provided with the outer ring edge 24 that can be equipped in nut 10 rank portions 11, and its other end predetermined position encircles in regular turn establishes first ratchet ring 21, second ratchet ring 22 and the supporting section 23 that forms salient point ring 211,221.

Clamp 30 is for being shorter in length than the hollow circular cylinder of intubate 20 length, the one end is provided with the interior ring edge 33 of combining closely with intubate 20 peripheries, its other end and intubate 20 first ratchet rings 21 salient point rings 211 opposite positions are provided with circular groove 31, form packing point ring 311 in circular groove 31 dual-side ora terminalis, in clamp 30 tail ends and intubate 20 second ratchet rings 22 are corresponding, be provided with the awl point that formation is meshed with second ratchet ring, 22 salient point rings 221 week and encircle 321 starting taper face 32.

Nut 10 and clamp 30 are sheathed on the intubate 20 in regular turn with loose fit and tight fit respectively, and the outer ring edge 24 that makes intubate 20 is equipped in nut 10 rank portions 11 and make the ring salient point 211 of intubate 20 first ratchet rings 21 corresponding with the circular groove 31 of clamp 30, and intubate 20 supporting sections 23 extend outside the clamp 30.

During winding, as shown in Figure 3, Figure 4, will by plastic cement insulating outer layer 41, be coated on plastic cement insulating outer layer 41 inside foam material core 42 and be coated on the cable 40 that the copper material leads 43 in the core 42 make and insert clamps 30, and making its core 42 be arranged in the

intubate

20,43 in its lead passes nut 10 by this; Then, make coniform cramping with packing cable 40 by instrument, make circular groove 31 mutual extrusion of first ratchet ring 21 and the clamp 30 of the intubate 20 that is in opposite position, the plastic cement insulating outer layer 41 of cable 40 is pressed in the circular groove 31, and spacing by the extruding of the packing point of clamp 30 circular grooves 31 dual-side ora terminalis ring 311 and first ratchet ring 21 salient point rings 211, form firm embedded structure body; And by the extruding that is meshing with each other of the salient point ring 221 of the awl point of clamp 30 tail end starting taper faces 32 ring 321 and intubate 20 second ratchet rings 22, make cable 40 towards 32 bending displacements of clamp 30 starting taper faces, make between cable 40 and the clamp 30 starting taper faces 32 closely connected seamlessly, can effectively avoid aqueous vapor to enter.

The utlity model has following effect: because the supporting section 23 of intubate 20 extends outside the clamp 30, when cable 40 is limited in the clamp 30 by packing after, 23 pairs of cables of supporting section, the 40 inner radial support power that form by intubate 20, can make cable 40 unlikely overflexings, can effectively avoid and 30 generations of clamp gap, block the purpose that aqueous vapor enters to reach.
