The basic interface of row communication.Generally, the power interface of embedded positioner, data transmission interface are exposed in air
In, in some harsh use environments, dust, steam etc. can influence the service life of these interfaces of positioner.
The content of the invention
The purpose of the present invention, which is that, provides a kind of positioner with dust-proof interface, and the interface of the positioner is set
There is interface sealing device, being capable of dust-proof, anti-steam.
Technical scheme is used by the present invention solves the above problems：
Positioner with dust-proof interface, including positioner housing, socket, offer on the positioner housing
Groove, the socket are arranged in groove and are also arranged with interface sealing device on socket；The interface sealing device includes solid
Determine ring, sealing shroud, closure, the socket is located in retainer ring center, rear end is stretched into positioner housing, front end is stretched out admittedly
Determine ring or concordant with retainer ring front end；The sealing shroud is set in outside retainer ring and being capable of sliding axially along retainer ring；It is described
Closure is connected on sealing shroud and can covered in sealing shroud front end.
As a further improvement on the present invention, the groove is a rectangular recess.
Further, the closure is connected on sealing shroud by a connecting rope.
Further, the closure is hinged on the side of sealing shroud.
Further, the sealing shroud outside wall surface is provided with latch.
Further, the sealing shroud is threaded in retainer ring.
Further, the retainer ring, closure, sealing shroud are made of silica gel or rubber.
To sum up, the beneficial effects of the invention are as follows：The present invention is provided with interface sealing device, interface in positioner interface
The retainer ring of sealing device is wrapped in outside socket, and the sealing shroud in retainer ring can move up in retainer ring axle, so as to
Sealing shroud is rotated to outside exposed socket when the plug portion being adapted with socket inserts socket or is not inserted into socket, to inserting
Mouth carries out proofing dust and protecting.When plug is not inserted into socket, closure can also be covered on sealing shroud, by spigot seal close
In space between capping and retainer ring, realize that dust and water protection vapour is protected, extend socket service life.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Mark and corresponding parts title in accompanying drawing：1- positioner housings；2- grooves；3- sockets；4- retainer rings；5-
Sealing shroud；51- latches；6- closures；7- connecting ropes.
Embodiment
The present invention will now be described in further detail with reference to the accompanying drawings and the accompanying drawings, but embodiments of the present invention
Not limited to this.
Embodiment 1：
As shown in figure 1, the positioner with dust-proof interface, including positioner housing 1, socket 3, the positioner
Offer a rectangular recess 2 on housing 1, the socket 3 is fixedly mounted in groove 2 and to be also arranged with interface on socket 3 close
Seal apparatus.
The interface sealing device includes cylindric retainer ring 4, hollow cylindrical sealing shroud 5, is connected on sealing shroud 5
Closure 6.
The socket 3 is located in the center of retainer ring 4, is fixed with the position of retainer ring 4；Stretched from the bottom land of groove 2 rear end of socket 3
Enter in positioner housing 1, electric signal is provided for the circuit in positioner；The front end of socket 3 is concordant with the front end of retainer ring 4, just
In the plug that connection is adapted therewith.
The sealing shroud 5 be set in retainer ring 4 it is outer and can sliding axially along retainer ring 4, the internal diameter of sealing shroud 5 is bigger
In the external diameter of retainer ring 4, it is easy to slip of the sealing shroud 5 in retainer ring 4, but is unlikely to stay between retainer ring 4 and sealing shroud 5
There is larger gap.The internal diameter of sealing shroud 5 and the external diameter difference of retainer ring 4 are no more than 0.3cm.
