Detailed description of the invention
Fig. 1 is the structural schematic diagram of one embodiment of the connector in the present invention with sealing protection function;
Structural schematic diagram when Fig. 2 is inner conical surface and the sealing ring press cooperation in Fig. 1 on outer housing;
Fig. 3 is the cooperation schematic diagram of inner conical surface in Fig. 2, bonding set, sealing ring.
Specific embodiment
A kind of implementation of the connector with sealing protection function is for example shown in Fig. 1 ~ 3: including plug 1 and sealing mechanism,
Sealing mechanism includes the outer housing 7 that the bracket 2 that front end is inserted terminal and opposite bracket can be rotated and be moved forward and backward, outer housing 7
Front end sets left and right for the crank slot 14 with intermateable connector locking cooperation.Plug 1 is set in bracket, and sealing mechanism further includes setting
The bonding set 13 being placed in bracket, plug 1 is Optical fiber plug in the present embodiment, the cable of the tail end connection optical cable 8 of plug 1 when use
Core, bonding set 13 are stepped shaft structure, and the bonding set of stepped shaft structure includes the major diameter section 13-2 and path section 13- of front and back setting
The inner peripheral surface of 1, path section 13-1 are the bonding cooperation section for cooperation Nian Jie with the sealing of the outer peripheral surface of optical cable, and major diameter section guiding is moved
Dynamic to be assemblied in the inner hole of bracket, back-end support is provided with the block direction platform being used between major diameter section, path section facing forward
Terrace block cooperates and limits the turn edge 12 that bonding covers moving limit backwards.There is the outer peripheral surface of path section sealing ring to cooperate section
24, the rear end of bracket 2 is provided with sealing ring 5, and sealing ring includes the connector part 5-1 and sealing body portion 5-2 that front and back is arranged,
The inner circumferential of connector part 5-1 is sequentially set with sealing ring connection land 20 along the longitudinal direction and connects annular groove 21 with sealing ring, props up
Frame tail end, which is provided with, connect land, the bracket connection annular groove 22 that sealing ring connection annular groove adapter connects and bracket connection with sealing ring
Land 23, the rear end face of bracket connection land extend perpendicularly to front-rear direction and connect with the front end face of sealing body portion 5-2
Touching cooperation.Outer housing tail end is provided with for squeezing sealing ring 5 and the inner peripheral surface for sealing body portion and sealing ring is made to cooperate section 24
The top pressure face 15 of cooperation is sealed, top pressure face is an inner conical surface, seals and is provided with indent between body portion and connector part
Step 6, the step 6 make seal body portion 5-2 be easier to be deformed.The expression of figure middle term 10 is set to bonding set and tail
Annular groove between portion's sheath 9, filling makes bonding set be connected with tail portion sheath injection molding body in annular groove.
In use, plug and bracket and intermateable connector grafting are moved forward simultaneously rotation case body, the song on outer housing
The cooperation of the bail of slot and intermateable connector, the outer housing movement of Chao Qianing while rotating, during being somebody's turn to do, the top pressure face on outer housing
The sealing body portion of pushing tow sealing ring and make to seal body portion flexible deformation inwardly, due to bonding set provides one for sealing ring can
The support leaned on, therefore bonding covers between the inner peripheral surface of sealing body portion, the front end face of bracket connection land and sealing body portion
