Detailed description of the invention
The enforcement of a kind of adapter with sealing protection function is such as shown in Fig. 1 ~ 3: include plug 1 and sealing mechanism,
Sealing mechanism includes support 2 that front end is inserted terminal and the rotatable and movable shell body 7 of opposite brackets, shell body 7
Front end sets left and right for locking friction tight crank slot 14 with intermateable connector.Plug 1 is arranged in support, and sealing mechanism also includes setting
The bonding set 13 being placed in support, in the present embodiment, plug 1 is Optical fiber plug, and during use, the tail end of plug 1 connects the cable of optical cable 8
Core, bonding set 13 is multidiameter structure, and the bonding set of multidiameter structure includes big footpath section 13-2 and path section 13-front and back arranged
1, the inner peripheral surface of path section 13-1 is the bonding cooperation section for sealing bonding cooperation with the outer peripheral face of optical cable, and big footpath section guides moves
In the dynamic endoporus being assemblied in support, back-end support be provided with block direction forward for the platform between big footpath section, path section
Terrace block coordinates and limits in bonding set moves the limit backwards and turn edge 12.The outer peripheral face of path section has sealing ring and coordinates section
24, the rear end of support 2 is provided with sealing ring 5, and sealing ring includes connector part 5-1 and seal part 5-2 front and back arranged,
The inner edge fore-and-aft direction of connector part 5-1 is sequentially set with sealing ring and connects land 20 and sealing ring connection annular groove 21,
Frame tail end is provided with and is connected land, the support connection annular groove 22 of sealing ring connection annular groove adaptation clamping and support connection with sealing ring
Land 23, the rear end face of support connection land extends perpendicularly to fore-and-aft direction and the front end face with seal part 5-2 connects
Touch and coordinate.Shell body tail end is provided with and makes inner peripheral surface and the sealing ring section of cooperation 24 of seal part for crush seal circle 5
Sealing the top pressure surface 15 coordinated, top pressure surface is an inner conical surface, is provided with indent between seal part and connector part
Step 6, this step 6 makes seal part 5-2 be easier to be deformed.Figure middle term 10 expression is arranged at bonding set and tail
Annular groove between portion's sheath 9, fills in annular groove and makes bonding set be connected with afterbody sheath injection molding body.
During use, by plug and support and intermateable connector grafting, move forward and rotation case body, the song on shell body
Groove coordinates with the bail of intermateable connector, and shell body rotates and moves forward, during being somebody's turn to do, and the top pressure surface on shell body
The seal part of pushing tow sealing ring and make seal part elastic deformation inwardly, due to bonding set for sealing ring provide one can
The support leaned on, between the most bonding set and the inner peripheral surface of seal part, support be connected the front end face of land and seal part
Between and the rear end of seal part and top pressure surface between be respectively formed reliably sealing, it is ensured that the sealing effectiveness of product；Due to viscous
The secure support of female connector, therefore can save telescopic claw structure, and while simplifying product structure, also making to push up pressure surface can be with close
Envelope body portion reliable contacts seals；Sealing ring is connected with support by boss, groove structure, easy to assembly, the most detachable, side
Just change.
In other embodiments of the invention, it is achieved the locking mechanism that shell body is locked with intermateable connector may not be
Crank slot, such as connection screw thread is set on shell body；Certainly shell body can also be transferred to lock with intermateable connector by obstructed overwinding
Tightly, say by screw by fixing for shell body with on intermateable connector, now shell body need not rotate and only can relatively prop up
Frame moves forward and backward, and now top pressure surface may not be inner conical surface structure, such as top pressure surface can be that bearing of trend is with front
Rear is to the ramp structure being obliquely installed；Certainly top pressure surface can also is that the spherical structure of evagination；Bonding set can also be fixed on
On support；Sealing ring can not also be connected by boss, groove structure with support, such as sealing ring is bonded and fixed to support
On；Adapter can also is that the electric connector realizing electric current transmission or the signal connector realizing signal transmission.
The enforcement of sealing mechanism is such as shown in Fig. 1 ~ 3: in the concrete structure of sealing mechanism and above-mentioned each adapter embodiment
Described sealing mechanism is identical, is not described in detail in this.
