Cable and the optical connector of interior cables connection are registered one's residence at networking and are widely used in engineering.Authorization Notice No. is
CN100573213C, authorized announcement date disclose a kind of external cable connection for the Chinese invention patent on December 23rd, 2009
Device, including plug and tail accessory with contact, tail accessory is locking nut, combined cover and bonding including sealing shroud
Set, sealing shroud is set in the outside of combined cover, and the afterbody of sealing shroud and combined cover is equipped with throat structure, and outdoor optical cable is from combination
The position that the afterbody of set extends forwardly into combined cover openend is provided with the plug coordinated with socket grafting, and outdoor optical cable is stretching into knot
Connected at position in trap with Nian Jie set, the front end of the afterbody throat structure of combined cover, which is provided with, to be used to keep off in a rearward direction
The block step of set is only bonded, when outdoor optical cable receives pulling force backward, block step is spacing by the block to bonding set
Realize the tension of optical cable.
Plug when in use, is first inserted on socket by the external fiber optic cable connector, by the attaching nut of combined cover front end with
Socket casing is connected, then the external screw thread by sealing shroud forward with combined cover front end is connected, and passes through the throat structure of sealing shroud afterbody
Shrink the throat structure of combined cover afterbody and pack tightly outdoor optical cable, so as to reach combined cover and the sealed mesh of outdoor optical cable
's.This external fiber optic cable connector is in actual use, if compared rearward by the position of the socket on plug connector, then plug
Need to stretch into the inside of Socket casing longer distance with socket grafting, then combined cover is now connected to Socket casing again
After upper, the rear end of the bonding set in combined cover be possible to also have a certain distance apart from the block step of combined cover and not with
Block step is contacted, and such outdoor optical cable is not just fixed in the axial direction, when being pulled by external force backward, outdoor optical cable energy
Enough move back up bonding set rear end contacted with the block step of combined cover, during this section of displacement, plug and
Socket has just been separated, and causes Joint failure, therefore, this external fiber optic cable connector when in use, due to outdoor optical cable not
The connection stable with combined cover is can guarantee that, and causes plug to be connected insecure problem with socket.
The content of the invention
It is an object of the invention to provide a kind of connector, the outdoor optical cable connector to solve prior art is being used
When bonding set it cannot be guaranteed that the problem of being relatively fixed all the time with combined cover and cause optical cable Joint failure.
In order to solve the above-mentioned technical problem, connector of the invention is adopted the following technical scheme that：A kind of connector, including tail
Department enclosure, the tail accessory includes being provided with the bonding set for being used for connecting outdoor optical cable, the tail of combined cover in combined cover, combined cover
