Embodiment
A kind of embodiment of connector encapsulation fitting; In Fig. 2 ~ 5; The front portion of the outer peripheral face of the annex sleeve 13 of this connector encapsulation fitting is arranged with coupling nut 10; The endoporus back segment of coupling nut 10 cooperates with the outer peripheral face of annex sleeve 13, is provided with on both mating surfaces coupling nut 10 is fixed on the jump ring 12 on the annex sleeve 13, and it is identical with fixed form of the prior art that jump ring 12 is fixed on the annex sleeve 13 fixed form with coupling nut 10.The endoporus leading portion of coupling nut 10 is provided with internal thread, and coupling nut 10 is fixed on the connector through the internal thread of its endoporus leading portion setting, realizes being connected of connector encapsulation fitting and connector.Coupling nut 10 is provided with the radial screw bore that runs through; Screw thread is installed with holding screw 20 in these radial screw bore; After coupling nut 10 is screwed on the connector; The holding screw 20 of screwing makes its inner face hold out against with connector to cooperate, prevent to cause coupling nut by falling down on the connector because screw thread gets loose.The endoporus leading section of annex sleeve 13 is provided with O shape circle groove is set, and O shape circle is provided with and is provided with O shape circle 11 in the groove, and O shape circle 11 is used for being sealed and matched with connector.The rear end of annex sleeve 13 has the shutoff end 19 that the open rearward end of annex sleeve 13 is sealed up, and the rear end face of shutoff end 19 is provided with three output cylinders 14, and each output cylinder 14 all is communicated with the endoporus of annex sleeve 13.Be provided with sealing ring 15 in the endoporus of each output cylinder 14, sealing ring 15 is the tubular sealing ring, and the endoporus side face of the outer peripheral face of sealing ring 15 and output cylinder 14 is sealed and matched.The endoporus hole wall of output cylinder 14 is provided with the positioning table terrace towards the rear end, and the front end face of sealing ring 15 cooperates with this positioning table terrace roof pressure.The rear end face of sealing ring 15 does not extend on the rear end face of output cylinder 14; The endoporus back segment of output cylinder 14 also slides and is inserted with a compacting ring 17; The leading portion of compacting ring 17 is plugged in the endoporus of output cylinder 14, and the front end face of compacting ring 17 cooperates with the rear end face roof pressure of sealing ring 15.The ring-type of turning in being provided with on the rear end face of the rear end face of compacting ring 17 and clamp nut 16 18 roof pressures that turn edge cooperate; The endoporus side face of clamp nut 16 is provided with internal thread, and clamp nut 16 revolves the outer peripheral face rear end that is located at annex sleeve 13 through the internal thread that is provided with on its endoporus side face.Positioning table terrace roof pressure on the endoporus hole wall of the front end face of sealing ring 15 and output cylinder 14 cooperates, and the rear end face of sealing ring 15 cooperates through compacting ring 17 and ring-type 18 roof pressures that turn edge, thereby realizes sealing ring 15 fixing in output cylinder.
In use; Different cables passes each self-corresponding ring-type turn edge 18 endoporus, the endoporus of compacting ring, the endoporus of sealing ring successively, passes the endoporus of coupling nut then jointly, and the heart yearn of each cable links to each other with the corresponding contact of connector; After carefully connecting the wire, earlier coupling nut is revolved and be located on the connector; Then the annex sleeve is assemblied on the coupling nut, the clamping nut of screwing then, clamping nut compresses sealing ring through compacting ring; Make the outer peripheral face of sealing ring cooperate more closely with the inner hole wall of output cylinder; The endoporus side face and the cable of sealing ring are sealed and matched closely, and the realization cable only moves with the sealing of output cylinder and cooperates, and cable and output cylinder are tightened together; Make the cable upper pulling force pass to the annex sleeve and pass to connector, prevent that the binding site between the contact of cable and connector is stressed through the annex sleeve.
O shape circle in the foregoing description is arranged on the endoporus side face of annex sleeve, also can be arranged on the outer peripheral face of connector, and the connector encapsulation fitting just can not be provided with sealing ring like this.
The fixed structure that the annex sleeve is fixed on the connector in the foregoing description is the coupling nut that is arranged on the outer peripheral face front end of annex sleeve; Also coupling nut can be set; Let the leading portion of annex sleeve serve as fixed structure; With being set on the connector of annex sleeve, with the enclosure interior of screw, realize that the connector encapsulation fitting is fixing on connector then by the outer peripheral face screw-in connector of annex sleeve.Or directly adopt jump ring that the annex sleeve is fixed on the connector.
Output cylinder in the above-mentioned instance is three, when reality is used, the number of output cylinder can be set according to the concrete radical of the cable of concrete connector rear end setting.
The O type circle that is used in the foregoing description being sealed and matched with connector also can change other forms of sealing ring into.
Sealing ring in the foregoing description is that the positioning table terrace that is provided with on the inner hole wall through output cylinder and screw thread revolve the clamp nut that is located on the annex sleeve outer peripheral face and be implemented in fixing in the output cylinder, and the rear end face of sealing ring also can be located at that collar stop is fixed in the output cylinder in the annex sleeve endoporus with revolving through the screw thread that is provided with on the outer peripheral face.This in the prior art that parts are fixed on the mode in the cylindrical shell is a lot, enumerates no longer one by one at this.
The rear end face of the sealing ring in the foregoing description keeps off the interference fit of bearing down on one through the ring-type of a compacting ring and clamp nut; Also compacting ring can be set; The direct roof pressure of rear end face that makes sealing ring is on the ring-type of clamp nut turns edge; At this moment sealing ring will extend the endoporus of output cylinder always and cooperate with the ring-type roof pressure that turns edge, and at this moment the rear end of sealing ring does not have the inner hole wall constraint of output cylinder, and its sealing effectiveness can variation; Sealing effectiveness when compacting ring is set is good, but can realize the purpose that seals.
