By twisting force, produce rotation with connector shell and cause crust phenomenon of rupture, thus causing between cable and adapter
Contact unstable and cause distortion or the inefficacy of transmission signal, how can guarantee that cable and the firm connection of adapter are not broken
Badly it is ensured that the transmitting of radiofrequency signal is the problem needing to solve.
Content of the invention
In order to solve the problems referred to above of prior art presence, this utility model provides a kind of electricity with rotation protection device
Cable connector, is ensured not producing torsion between cable and shell by the clamping of lug and groove, is avoided by arc transiting surface
The destruction of cable sheath, thus ensure the stable transmission of radiofrequency signal.
The technical scheme that this utility model is adopted is: a kind of cable connector with rotation protection device, including shell,
First packing ring, second packing ring and fastening swivel nut, described shell are provided with cavity, are provided with female thread in described cavity, described
First packing ring, described second packing ring and described fastening swivel nut are arranged in described cavity, and described first packing ring is positioned at described
Between second packing ring and described fastening swivel nut, described fastening swivel nut is connected with described outer casing screw, and described first packing ring is arranged
There is rotation protection device, described first packing ring is fixedly connected with described shell by described rotation protection device.
Further, the diameter of described first packing ring is consistent with the diameter of described cavity, and the diameter of described second packing ring is little
In described cavity diameter.
Further, described rotation protection device includes lug, described lug be from the circumference of described first packing ring towards
Outside extension is formed, and described inside the shell is provided with the groove being adapted with described lug specification.
Further, the position opening of described first bead interior being contacted with cable sheath is provided with arc-shaped transition
Face.
The beneficial effects of the utility model are:
1st, this utility model, using the clamping of the lug on the first packing ring and shell upper groove, solves cable not well
And then the problem that can rotate with the fastening rotation of swivel nut, thus not produce the torsion to cable sheath it is ensured that cable with
The firm connection of adapter is it is ensured that the firm transmission of radiofrequency signal.
2nd, this utility model passes through to be provided with arc transiting surface on the first packing ring opening, after cable sheath passes through the first packing ring
To both sides turn down when arc transition will not to crust produce cut folding power, efficiently avoid the cable sheath that right angle solitarily causes
Rigidity fractures, and is that cable connector is widely applied and provides more guarantees.

Specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below will be to technology of the present utility model
Scheme is described in detail.Obviously, described embodiment is only a part of embodiment of this utility model, rather than all
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not before making creative work
All other embodiment obtained by putting, broadly falls into the scope that this utility model is protected.
As shown in figure 1, this utility model provides a kind of cable connector with rotation protection device, including shell 1,
One packing ring 3, second packing ring 9 and fastening swivel nut 4, shell 1 are provided with cavity, are provided with female thread in cavity, the first packing ring 3,
Second packing ring 9 and fastening swivel nut 4 are arranged in cavity, and the first packing ring 3 is located between second packing ring 9 and fastening swivel nut 4, tightly
Gu swivel nut 4 is threadeded with shell 1, the first packing ring 3 is provided with rotation protection device, the first packing ring 3 passes through rotation protection dress
Put and be fixedly connected with shell 1.
As shown in Figures 2 and 3, the cavity of shell 1 is arranged fluted 6, the starting point of groove 6 is located at shell 1 right-hand member,
Groove 6 is adapted along the axis direction setting of shell 1, the depth of groove 6 with the height of lug 7.
As shown in Figure 4 and Figure 5, rotation protection device includes lug 7, and lug 7 is the circumference facing external from the first packing ring 3
Extend and formed, the position that the opening on the first packing ring 3 is contacted with cable sheath 2 is provided with arc transiting surface 8.
