Background

Existing connectors have been widely used in outdoor and underwater environments, and thus the performance requirements for connector sealing and waterproofing have also become higher and higher. The existing electric connector generally adopts a plug and a socket butt joint tail welding wire, a head shell of the plug extrudes a sealing ring inside the socket to realize a waterproof function, the cable has downward pulling force relative to the connector due to dead weight, the tail cable can drive the head shell to generate relative deflection after the butt joint of the head seat of the connector, the pressure distribution of the extrusion part of the head shell and the sealing ring is uneven, a socket sealing ring is stressed at a smaller position to generate a gap with the head shell, water can permeate the core group from the head shell, and therefore the waterproof failure is caused.

SUMMERY OF THE UTILITY MODEL

Inside the first casing infiltration core group of connector can be followed to the normal water to prior art to lead to the waterproof problem of becoming invalid of connector, the utility model provides a circular connector with dual waterproof construction, the rubber gasket and the sealing washer of this connector exert waterproof sealing effect simultaneously.

A circular connector with a double waterproof structure comprises a socket, a plug, a word sequence, a seat shell, a head shell, a clamping cap, a sealing ring and a rubber gasket; the socket is butted and locked with the plug, the sealing ring is pressed with the head shell, and the rubber gasket in the plug is pressed with the seat shell; the inner ring and the outer ring of the rubber gasket in the plug are respectively attached to the outer circle of the head shell and the inner circle of the clamp; the outer diameter of the sealing ring in the socket is attached to and filled in the inner groove of the seat shell.

Preferably, the word order is the same as the height of the seal ring.

Preferably, a gap exists between the seat housing and the rubber gasket.

Preferably, the thickness of the rubber gasket is smaller than that of the sealing ring, and the compression amount of the rubber gasket is smaller than that of the sealing ring.

Compared with the closest prior art, the utility model provides a technical scheme has following beneficial effect:

the utility model discloses produce the condition of waterproof inefficacy and carry out configuration optimization after the butt joint to the connector, locate to increase the rubber gasket at first casing for plug and socket butt joint end all has the rubber spare extrusion to realize sealing. The head shell is in contact with the sealing ring inside the socket to form extrusion, the seat shell is extruded with the rubber gasket inside the plug to form double waterproof, and the socket and the rubber gasket can also maintain the extrusion state under the condition that the sealing of the plug and the sealing ring is invalid, so that sealing is realized.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a circular connector with dual waterproof construction, includes socket 1, plug 2, preface 3, seat casing 5, first casing 6, card cap 7, sealing washer 4, rubber gasket 8. The plug 2 is in butt joint and locking with the socket 1, the head shell 6 is in press fit with the seat inner sealing ring 4, and the seat shell 5 is in press fit with the rubber gasket 8 in the plug 2, so that butt joint sealing is realized. The inner ring and the outer ring of the rubber gasket 8 in the plug 2 are respectively attached to the outer circle of the head shell 6 and the inner circle of the clamping cap 7, and are extruded by the seat shell 5 during locking to generate elastic deformation, so that water entering from the inner cavity of the clamping cap 7 is blocked, and a certain waterproof sealing effect is exerted. The outer diameter of a sealing ring 4 in the socket 1 is attached to and filled in an inner groove of a seat shell 5.

Further, when the plug 2 is locked, the inner head shell 6 contacts the sealing ring 4, and the sealing ring 4 is extruded and deformed under the stress. Because the word sequence 3 is equal in height with the word sequence, the sealing ring 4 cannot deflect inwards or outwards, axial compression of the sealing ring 4 is guaranteed, and a waterproof sealing effect is achieved.

Further, when the plug 2 is just in contact with the packing 4, the packing 4 is not elastically deformed, and a gap is formed between the seat housing 5 and the rubber gasket 8. Because the thickness of the rubber gasket 8 is smaller than that of the sealing ring 4, the compression amount of the rubber gasket 8 is also smaller than that of the sealing ring 4, and the compression amounts of the rubber gasket 8 and the sealing ring 4 are approximately the same due to the gap, so that the rubber gasket 8 and the sealing ring 4 can play a waterproof sealing role at the same time.

The utility model discloses dual waterproof principle does: rubber gasket 8 is packed into first casing 6, and after plug 2 and socket 1 butt joint, first casing 6 and the inside sealing washer 4 contact of socket 5 form the extrusion, and seat casing 5 and the inside rubber gasket 8 extrusion of plug 2 form dual waterproof.

The utility model discloses produce the condition of waterproof inefficacy and carry out configuration optimization after the butt joint to the connector. The rubber gasket is added at the head shell, so that the butt joint ends of the plug and the socket are extruded by the rubber piece to realize sealing. When the socket is locked, the plug inner head shell is in contact with the sealing ring, the sealing ring is extruded and deformed under stress, the socket inner seat shell is in contact with the rubber gasket, and the rubber gasket is extruded and deformed. Under the vibration environment or because the influence of cable dead weight, afterbody cable drives first casing and produces relative deflection, and head casing and sealing washer extrusion department pressure distribution are inhomogeneous, and the unilateral atress of sealing washer produces the space with the sealing washer. At this time, the rubber gasket inside the head shell is still extruded with the socket shell, and the socket and the rubber gasket are sealed. Even if the plug and the sealing ring are sealed and invalid, the socket and the rubber gasket can also maintain the extrusion state, and sealing is realized.

The above embodiments are only used to illustrate the technical solution of the present invention and not to limit the same, although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify or equally replace the specific embodiments of the present invention, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention is within the protection scope of the claims of the present invention.
