Stop section is made of the tooth top of end-tooth or the slot bottom of end face groove.
Have the rear end for being used for stretching into connector shell in mating sleeve in the front side of rotation stop inserting structure stretches into part,
The periphery for stretching into part is provided with for the sealing ring with connector shell sealing cooperation.
The rear end of locking nut is provided with interior land on front side of rear mating surface, and the rear end of mating sleeve is limited by rear mating surface
Position and cannot from front to back by deviating from rear side of locking nut, be provided with mating sleeve on rear side of interior land for and interior land
Block coordinates and prevents mating sleeve by rear to the preceding flexible barbs by abjection on front side of locking nut.
Beneficial effects of the present invention are：In use, the direct spinning of the locking nut of screening accessory is on connector shell,
During locking nut screws, locking nut moves forward, and preceding mating surface is moved forward by waterproof apron with mating sleeve, directly
Device housing block is connected to the stop section of mating sleeve, forward and backward mating surface acts on waterproof apron, and waterproof apron compresses cable
Realize sealing, the present invention is directly coordinated with connector shell by locking nut, is not required to additionally set intermediate transit set, can not only
Enough reduce the entire length of connector, additionally it is possible to only need once to screw the assembling that screening accessory and connector are just capable of in action, group
Dress process is simple and convenient.
Brief description of the drawings
Fig. 1 is the structure diagram of the prior art in the present invention；
Fig. 2 is the structure diagram of one embodiment of connector in the present invention；
Fig. 3 is the exploded view for lacking dustproof cover in Fig. 2.
Embodiment
The implementation of water-proof connector is for example shown in Fig. 2 ~ 3：Connector shell 2 including being provided with contact 4, connector case
The tail end of body is provided with screening accessory, and screening accessory includes the lock that spinning extends along the longitudinal direction in the axis on connector shell
Tight nut 9, is provided with the mating sleeve 7 that axis extends along the longitudinal direction in locking nut 9, in mating sleeve 7, locking nut 9
With the preceding mating surface 13 and rear mating surface 11 being oppositely arranged, in the rear end of locking nut 9 is provided with front side of rear mating surface
Land 14, the rear end of mating sleeve 7 by rear mating surface it is spacing and cannot be from front to back by deviating from rear side of locking nut, mating sleeve
On be provided with rear side of interior land for interior land block coordinate and prevent mating sleeve by it is rear to preceding by locking nut before
The flexible barbs 15 of side abjection, the overall assembling of locking nut and mating sleeve, i.e. mating sleeve can be realized by the structure not
Can be by deviating from locking nut.Waterproof apron 8 and oiled washer 12 have been sequentially arranged between forward and backward mating surface along the longitudinal direction,
Waterproof apron is loaded on corresponding cable for sealing shroud, and oiled washer can be rotatably assorted with rear mating surface, and can play prevents
Locking nut drives the effect that waterproof apron rotates.Rotation stop is provided between mating sleeve and connector shell and inserts fit structure
16, rotation stop inserting structure includes the end-tooth being arranged in mating sleeve and the end face groove being arranged on connector shell, end face
The tooth top of tooth, which is formed, to be used to coordinate with connector shell block to limit the stop section of mating sleeve orward movement limit.Engagement sleeves
There is the periphery stretched into part, stretch into part for the rear end for being used to stretch into connector shell on cylinder in the front side of rotation stop inserting structure
It is provided with the sealing ring 6 for coordinating with connector shell sealing.Figure middle term 3 represents insulator, and item 5 represents grommet, item 10
Represent dustproof cover；Item 1 represents coupling nut.
When making line, cable is connected by screening accessory by rear to preceding through thickness with contact tail end, then by screening accessory
Locking nut spinning is on connector shell, and for locking nut during screwing, rear mating surface passes through oiled washer, marine glue
Circle moves forward with mating sleeve, and the end-tooth in mating sleeve is inserted into the groove of connector shell upper surface from rear to preceding,
So it is prevented that locking nut drives mating sleeve to rotate in rotary course, until the tooth top of end-tooth withstands end face groove
Slot bottom, locking nut continues to screw, and waterproof apron is deformed and seals stirrup cable, and line process is done in realization.Entirely do
Line process only needs to screw locking nut once, simple and convenient, simultaneously because eliminating intermediate transit set, also significantly reduces waterproof
The entire length of connector so that this water-proof connector can be adapted in the narrow and small cabinet of communication equipment of installation space.
In the other embodiments of this water-proof connector：Oiled washer can not also be set, and rear mating surface can be direct at this time
Press to waterproof apron；The elasticity in interior land and mating sleeve on locking nut can not also be set to thorn, not made at this time
Used time, locking nut and mating sleeve are separately set, and will be just assembled together when in use both it；End-tooth, end face groove
Set position to replace, such as end face groove is set in mating sleeve, end-tooth is set on connector shell, at this time
The slot bottom of end face groove forms stop section；Certain end-tooth, end face groove can be replaced with other rotation stop inserting structures such as key, keyway,
Stop section can be arranged on key, on keyway at this time, can also be arranged at the other positions of mating sleeve；Certain rotation stop inserting structure
It can not also set.
The implementation of screening accessory is for example shown in Fig. 2 ~ 3：The concrete structure of screening accessory is implemented with above-mentioned each water-proof connector
Screening accessory described in example is identical, and this will not be detailed here.
