Rubber ring.
2nd, there is baffle plate the end of external thread sleeve, and the decrement of rubber ring is controlled, and prevents overvoltage from leading to lead outside cable
The damage of body.
3rd, the fastening swivel nut material on cable fixed cover is metal, and intensity increases so that connecting more firm.
4th, set up rubber ring in fastening swivel nut so that rubber ring is extruded when cover screwing fixed by cable, distension cable is fixed
The inner chamber of set, on the one hand makes adapter more firm with the connection of cable, on the other hand makes sealing effectiveness more preferably, is easy to reveal
It uses.
5th, after solid swivel nut is tightened, the width of described rubber ring is more than or equal to a pitch of cable outer conductor so that cable
Uniformly extruded within one week of outer conductor, be connected firmly, transmission signal is uniform and stable, when tail cable shake, shake can be reduced
Dynamic, increase protection.
6th, the structure of cable fixed cover is simplified, and eliminates the inner chamber of its rear end and female thread so that cable fixed cover
Size reduces, and processing is convenient, and cost reduces.
7th, the contact surface of adapter outer conductor rear end and cable outer conductor is set to tapered electrolysis, and extruding force increases, and connects
Touch even closer, improve laser propagation effect.
8th, the front end setting internal screw thread of cable fixed cover, helical form cable outer conductor is compressed by internal screw thread.Extruding force increases
And uniformly, contact is even closer, improves laser propagation effect.
Due to not having an impact prior art standard, therefore can be with the mother of various constructed standards of the prior art
Joint connects, and has good versatility.
