Packing pawl cover 22 has a ring body 221, and this ring body 221 is an annulus, and packing pawl cover 22 extends equally spaced plural L type calvus 222 from ring body 221.

The compound mode of the water repellent component 2 of the utility model is that to utilize the packing pawl to overlap 22 sheathed and tighten waterproof jacket 21, and ring body 221 respective slot 214 are chimeric, each L type calvus 222 corresponding ring wall 215 and end face 216 interlockings; The effect of water repellent component 2 and effect are please with reference to the detailed description like Fig. 4 the 4th to Fig. 8.

Please refer to Fig. 4 to shown in Figure 7, the water-proof connector of the utility model is used for a cable 100, and this water-proof connector mainly comprises a pedestal 1, a water repellent component 2 and a fixed cover 3.

Pedestal 1 one ends are provided with a junction surface 11; Pedestal 1 other end is provided with a connection-peg 12; Cable 100 is arranged in pedestal 1 via junction surface 11; The part of junction surface 11 corresponding cables 100 is formed with an annular contact surface 111, and annular contact surface 111 is to tilt and 11 dwindle bore gradually towards connection-peg 12 directions from the junction surface, and the opening part at junction surface 11 is provided with internal thread 112 again.

Water repellent component 2 sheathed cables 100 also are placed in the junction surface 11; Water repellent component 2 comprises a waterproof jacket 21 and packing pawl cover 22, and waterproof jacket 21 has a body 211, and body 211 1 ends are extended with a protuberance 212 of corresponding annular contact surface 111; Protuberance 212 surfaces are formed with plural ring 213; Wherein, protuberance 212 outside tapered contractions, above-mentioned plural ring 213 is in protuberance 212 surperficial stepped arrangements; Again, be provided with a groove 214 between protuberance 212 and the body 211, body 211 is formed with a ring wall 215 and is formed with an end face 216 in the end away from protuberance 212; Packing pawl cover 22 has a ring body 221, and packing pawl cover 22 extends equally spaced plural L type calvus 222 from ring body 221; Wherein, packing pawl cover 22 is enclosed within outside the waterproof jacket 21, and ring body 221 respective slot 214 are chimeric, each L type calvus 222 corresponding ring wall 215 and end face 216 interlockings.

Fixed cover 3 corresponding junction surfaces 11 combine and compress water repellent component 2 to make waterproof jacket 21 folders pull between junction surface 11 and cable 100; Make each ring 213 produce distortion and be close to annular contact surface 111; Thereby make waterproof jacket 21 tighten cable 100, specify as follows, fixed cover 3 is formed with a pressing part 31 and is provided with the external screw thread 32 of corresponding internal thread 112; When fixed cover 3 screwed togather with junction surface 11 each other, pressing part 31 can tighten the solid waterproof jacket 21 of bundle by extruding packing pawl cover 22.

By this; Waterproof jacket 21 is tightly restrainted on cable 100, and is made waterproof jacket 21 folders via packing pawl cover 22 and fixed cover 3 and pulls between junction surface 11 and cable 100, to let the water-proof connector of the utility model have favorable waterproof property; Simultaneously; Each L type calvus 222 corresponding ring wall 215 and end face 216 interlockings, and the combinative stability degree of raising waterproof jacket 21 and packing pawl cover 22 is tightened cable 100 with strong fix waterproof jacket 21.

Compare down; Existing water-proof connector, because of the water-proof rubber sleeve surface is same plane, the part produces when being out of shape so receive the extruding of packing pawl cover; Can relatedly produce distortion with the whole plane that shell body contacts at water-proof rubber sleeve; Some can't be close to shell body to cause water-proof rubber sleeve, makes between water-proof rubber sleeve and the shell body and produces the slit, and the water proofing property of water-proof connector is reduced.

The water-proof connector of the utility model; Its fixed cover 3 compacting packing pawls covers 22 are pulled between junction surface 11 and cable 100 waterproof jacket 21 folders, because of the part of junction surface 11 corresponding cables 100 is formed with annular contact surface 111; One end of waterproof jacket 21 corresponding annular contact surfaces 111 is formed with a plurality of rings 213; This waterproof jacket 21 is squeezed and part when deforming, and is provided with ring 213 so be noncontinuous surface because of protuberance 212 surfaces, so the whole plane that protuberance 211 contacts with annular contact surface 111 can relatedly not deform; Can avoid producing the slit between waterproof jacket 21 and the annular contact surface 111, and then promote the waterproof effect of water-proof connector.

In addition, as shown in Figure 7, when each ring 213 is squeezed; Can distortion be close to annular contact surface 111; And form backstop ring together, and compare existing water-proof rubber sleeve surface under the same plane, each ring 213 of the utility model can more be stablized and positively touches annular contact surface 111; Cause can be not gapped between waterproof jacket 21, junction surface 11 and the cable 100 generation, and then increased the waterproof effect of water-proof connector.

Please refer to shown in Figure 8ly, be the user mode sketch map of the utility model water-proof connector, after wherein accomplish with cable 100 assemblings at the junction surface 11 of pedestal 1; Pedestal 1 other end is provided with connection-peg 12; This connection-peg 12 can be the public affairs end that is provided with stitch or has mother's end of answering connecting terminal, combines with relative respective socket 200, and the combination of completion connector; The water-proof connector of the utility model can be made the function of electronic signal transmission at this moment; And above-mentioned water repellent component 2 is used to protect water-proof connector, electrically connects to avoid connector itself to make moist destroying it, make connector keep good electrically.
