Fig. 1 is please referred to, Fig. 1 is a kind of waterproof joint structure schematic diagram provided by the embodiment of the utility model, including connector
Ontology 11, porous seal ring 14, packing cap 16 and nut 19.
The first through hole 141 passed through for cable is offered on the porous seal ring 14；The joint body 11 with it is described
Packing cap 16 is connected through a screw thread, and the packing cap 16 is connected through a screw thread with the nut 19.
The joint body 11 includes the first thread segment 111 and the second thread segment 112, and the packing cap 16 includes third spiral shell
Line section 161 and the 4th thread segment 162.In the present embodiment, the first thread segment 111 on the joint body 11 is external screw thread
Section, second thread segment 112 are external thread section, and the third thread segment 161 of the packing cap 16 is internal screw thread, the 4th thread segment
162 be external screw thread, and the screw thread of the nut 19 is internal screw thread.The third thread segment 161 of the packing cap 16 and the connector sheet
Second thread segment 112 of body 11 is threadedly coupled, and the 4th thread segment 162 is connect with the internal screw thread of the nut 19.
Intracavitary in the joint body 11, and the inner cavity with the joint body 11 is arranged in the porous seal ring 14
It is in close contact, the porous seal ring 14 includes at least two first through hole 141, in the case where there is more cables, every line
Cable can be each passed through the different first through hole 141 and be compacted, and improve the waterproof performance of cable.
Referring to figure 2., in the another embodiment of the present embodiment, the waterproof connector 1 further includes nut 12 and O-shaped
Sealing ring 13, the nut 12 are connect with the first thread segment 111 of the joint body 11, and 13 nesting of O-ring seal is set
It sets on the first thread segment 111 of the joint body 11, positioned at the first screw thread of the nut 12 and the joint body 11
Between section 111.
Referring to figure 3., Fig. 3 is the scheme of installation of stopper provided by the embodiment of the utility model, and the waterproof connector 1 is also
Including stopper 20, the shape of the stopper 20 is adapted to the first through hole 141 of the porous seal ring 14, embedding can be set on institute
It states in the first through hole 141 of porous seal ring 14.
The stopper 20 is for blocking the first through hole 141, when installing cable, if number of cables is less than described first
When the quantity of through-hole 141, the extra through-hole of the porous seal ring 14 can be blocked with the stopper 20, prevent water from passing through extra

It encloses and generates gap to influence waterproof performance.
It is worth noting that when installing cable, if number of cables is less than the quantity of the first through hole 141,
The extra through-hole that the porous seal ring 14 is blocked with the stopper 20 for being not provided with second through-hole 201, prevents water from passing through
Extra through-hole penetrates into waterproof connector, influences the service life of cable.
The utility model embodiment can produce different rule according to existing different cable diameter specification setting on the market
The stopper 20 of lattice, improves the versatility of waterproof connector 1, when in-site installation, it is only necessary to which the stopper 20 for taking different size can be complete
At installation, the waterproof ability of waterproof connector 1 had both been increased, while having also reduced field erected complexity.
In the utility model embodiment, the making material of the stopper 20 is rubber.Rubber material is that a kind of have can
The high elastic polymer material of inverse deformation, has very strong elasticity, even if second of stopper 20 used by during the installation process
When through-hole diameter is slightly less than the diameter of cable, under external force, the cable is still able to second across the stopper 20
Through-hole 201 is simultaneously fitted closely with the stopper 20, achievees the effect that waterproof.
Incorporated by reference to referring to Fig. 4, Fig. 5, in the utility model embodiment, the waterproof connector 1 further includes compressing member 15, institute
State that compressing member 15 is embedding to be set between the porous seal ring 14 and the inner cavity of the joint body 11, the compressing member 15 is used
In the compression porous seal ring 14 and by the cable of the porous seal ring 14, to prevent water via the porous seal ring
14 enter in the waterproof connector 1.
In embodiment mentioned above, the compressing member 15 is ring structure, is set up in the week of the ring structure
There is metal clips 151, the metal clips 151 clamps described more under by the effect of the pressure of the inner cavity of the joint body 11
Hole sealing ring 14 is in close contact the porous seal ring 14 with by the cable of the porous seal ring 14.
Fig. 6 is please referred to, Fig. 6 is a kind of the third structural schematic diagram of waterproof connector provided by the embodiment of the utility model,
The waterproof connector 1 further includes bellows-sheathed 17, ring type seal 18 and bellows 21；The bellows-sheathed 17 is set to described
