Abstract
The utility model provides a locking structure for a connector and a cable, which comprises an outer connector conductor, a welding sleeve, an outer cable conductor, a rear nut and a cable overshath. The tail end of the welding sleeve is of a closing structure whose outer wall is tapered; the welding sleeve is equipped with at least two slit grooves which are opened along the axial direction of the outer cable conductor; the inner wall of the rear nut is of a conical surface structure matched with the outer wall of the welding sleeve; and when the outer connector conductor and the rear nut are screwed, the conical surface structure of the rear nut presses the tail end of the welding sleeve, and the inner wall of the tail end of the welding sleeve is engaged with the cable oversheath. The locking structure for the connector and the cable has the advantages that connecting points of the connector and the cable include not only welding points of the outer connector conductor and the outer cable conductor but also the welding sleeve and the cable oversheath, thereby improving tensile capability of cable assemblies, and reducing the risk that the outer cable conductor is broken because of welding.
Description
Technical field
The utility model relates to the locking mechanism of a kind of connector and cable, relates in particular to a kind of connector of many impetus and the locking mechanism of cable.
Background technology
Being connected of the cable assembly combination of cable (connector with), adopt the connected mode of connector outer conductor and cable outer conductor welding usually.
Fig. 1 is the connector of prior art and the syndeton schematic diagram of cable.As shown in the figure, the connector of prior art and the syndeton of cable comprise: connector outer conductor 101, welding cover 102, cable outer conductor 103, back nut 104 and cable jacket 105, wherein, welding cover 102 fixes between connector and back nut 104 with being threaded of back nut 104 by connector outer conductor 101, and welding cover 102 is welded to connect with cable outer conductor 103.
Above-mentioned connected mode all has been applied to pad 31 places of welding cover 102 with cable outer conductor 103 with all mechanical stresses, the anti-drawing ability of test cable outer conductor 103.When cable outer conductor 103 is thinner, under the less situation of drawing ability, the phenomenon of cable outer conductor 103 fractures will occur, thereby make cable assembly reliably not connect.
The utility model content
Technical problem to be solved in the utility model improves the anti-pulling ability for how making the more reliable connection of cable assembly, and makes cable outer conductor reduce the risk that ruptures because of welding.
In order to solve the problems of the technologies described above, the utility model provides the locking mechanism of a kind of connector and cable, comprise the connector outer conductor, the welding cover, cable outer conductor, back nut and cable jacket, wherein, welding cover end is the tapered closing in structure of outer wall and is provided with at least two slots, slot is offered along the axial direction of cable outer conductor, the cone structure that the inwall of back nut matches for the outer wall with the welding cover, when screwing connector outer conductor and back nut, the end of the cone structure extruding welding cover of back nut, the inner wall at end and the interlock of cable jacket phase of welding cover.
As preferably, welding cover inner wall at end is convex-concave surface with interlock place of cable jacket phase.
As preferably, weld the cover inner wall at end and some fine threads are set and form described convex-concave surface.
As preferably, weld cover and be welded to connect with cable outer conductor.
The locking mechanism of connector of the present utility model and cable, taper closing in and slot structure by the terminal outer wall of welding cover, and cooperate the conical surface of back nut inwall to guide extrusion structure, make when screwing connector outer conductor and back nut, the end of the cone structure guiding of back nut inwall and extruding welding cover, inner wall at end and the cable jacket of welding cover are able to tight interlock.Structure like this, make the tie point of connector and cable not be confined to the pad of connector outer conductor and cable outer conductor, and extend on welding cover and the cable jacket, improve the anti-pulling ability of cable assembly, and reduced the possibility that cable outer conductor ruptures because of welding.

Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
Fig. 2 is the embodiment partial cutaway schematic diagram of the locking mechanism of connector of the present utility model and cable.As shown in the figure, the utility model provides the locking mechanism of a kind of connector and cable, comprise connector outer conductor 1, welding cover 2, cable outer conductor 3, back nut 4 and cable jacket 5, wherein, welding cover 2 fixes between connector and back nut 4 with being threaded of back nut 4 by connector outer conductor 1, and welding cover 2 is welded to connect with cable outer conductor 3.
Fig. 3 is the welding cover schematic diagram of embodiment of the present utility model.As shown in the figure, welding cover 2 ends are the tapered closing in structure of outer wall and are provided with six slots 21 offering along the axial direction of cable outer conductor 3.Fig. 4 is the back nut schematic diagram of embodiment of the present utility model.The cone structure of back nut 4 inwalls for matching with welding cover 2 outer walls.Referring to Fig. 2～4, when screwing connector outer conductor 1 and back nut 4, the end of the guiding of the cone structure of back nut 4 inwalls and extruding welding cover 2, the end and cable jacket 5 phase interlocks of feasible welding cover 2.Wherein, welding cover 2 inner wall at end are provided with some fine threads 22 with cable jacket 5 phase interlocks place.
As distortion, the number of slot 21 can determine according to the shape size of the needs of actual conditions or connector self, but more than at least two.And described welding is overlapped 2 inner wall at end and cable jacket 5 phase interlocks place and also can be set to other and have the arbitrary structures that strengthens the frictional force effect, such as the grid line of projection or simple rubbing surface.
The utility model is not confined to above-described embodiment; every by the distortion of welding cover with back nut; utilize back nut extruding welding cover; weld the principle of overlapping with the interlock of cable jacket phase thereby make; realize other any distortion of the utility model function, all within protection range of the present utility model.
