The insertion end 26 is located in the insertion portion 16 of the insulating core 12, which is tubular and defines a socket 30 having a pair of correspondingly disposed openings 32, so that the insertion end 26 has elasticity which is elastically stretched in the radial direction. At the same time, the above-mentioned hole 24 around the insertion end 26 is engaged, so that when the conductor 54 of the male connector 90 is inserted into the insertion hole 30 of the insertion end 26, there is sufficient clearance to expand outward in the radial direction, and then the elastic recovery force clamp is used. The conductor 54 of the male 90 is tightened to achieve an electrical connection effect. The hole 24 of the insulating core 12 is produced by a bushing (not shown) previously placed in the above-mentioned cavity to prevent the plasticized material from flowing into the plug end 26 of the conductor 14 to block the jack 30 when the insulating core 12 is injected. . The bushing remains in the cavity after the waterproof connector module 10 is injection molded, for the next recycle.

Another important part of the invention is that the conductor 14 comprises at least one groove 36. In the embodiment of the drawings, the conductor 14 includes three grooves 36 spaced between the insertion end 26 and the welding end 28, the groove 36 being radially recessed from the outer periphery of the conductor 14, adjacent to the two A flange 34 is formed between the grooves 36 to form a plurality of 90 degree right angles between the contact faces of the conductor 14 and the insulating core 12, thereby decompressing the layer of high pressure liquid infiltrated from the gap 38 therebetween. The liquid is prevented from penetrating to the joint of the welding end 28 and the wire 44, avoiding oxidation at the joint to cause a short circuit, and at the same time contributing to the bonding of the conductor 14 and the insulating core 12 to prevent loosening.

Thereafter, it is placed in the cavity of another plastic injection mold (not shown), and then the plastic material forming the protective cover 46 is preheated and plasticized, and then injected under pressure into the cavity to surround the cavity. The partial support portion 18 of the insulating core 12 is up to the front end of the wire 42 while retaining the nut 40 on the insulating core 12, thus being the desired female connector 50.

The support portion 18 has a plurality of spaced grooves 21 which are radially recessed from the outer peripheral portion of the support portion 18 and are formed between adjacent grooves 21 Form a flange 19. The wire 42 includes a plurality of spaced apart grooves 45 that are radially recessed from the outside of the front end of the wire 42. The grooves 21 and 45 function as the grooves 36 of the conductor 12, and the layer of the high-pressure liquid permeating from the gaps 23 and 43 between the protective cover 46 and the insulating core 12 and the electric wires 42 respectively can be decompressed to prevent high voltage. The direction leaks into the low pressure direction, while the combination of the protective sleeve 46 with the insulating core 12 and the wires 42 can be more secure.

According to the same principle, the waterproof connector module 10 can be slightly modified to form a module 10a suitable for use in a male connector. As shown in the fifth to seventh embodiments, the module 10a includes an insulating core 52 and a plurality of conductors 54, which are integrally molded by the same method as the above embodiment.

The slot has a guiding member 62 protruding inwardly from the slot wall, and can be inserted into the slot. The guide slots 20 of the portion 16 cooperate to guide the insertion portion 16 into the slot 60 correctly. The insertion portion 56 further includes a stopper 64 extending radially outward from the front end thereof to prevent the threaded sleeve 76 to be detached. The conductor 54 includes opposing plug ends 66 and soldering ends 68 that are located in the slots 60 of the insulative core 52 for insertion into the receptacles 30 of the conductors 14 to form electrical contacts; 68 extends beyond the support portion 58 of the insulative core 52 to electrically connect to a plurality of wires 80 of a wire 78 (as in the eighth diagram). The conductor 54 further includes at least one groove 72 radially recessed from the outer peripheral portion between the insertion end 66 and the welding end 68, and a flange 70 is formed between the adjacent two grooves 72, whereby the conductor can be 54 forms a plurality of 90 degree right angles with the contact surface of the insulating core 52 to decompress the high pressure liquid layer infiltrated from the gap 74 therebetween to prevent liquid from penetrating to the joint of the welding end 68 and the wire 80, avoiding the The junction is oxidized to cause a short circuit.

The eighth figure is a male connector 90 made using the above waterproof connector module 10a. As with the method of manufacturing the female connector 50, a threaded sleeve 76 that matches the nut 40 is placed over the plug portion 56 of the insulating core 52, and each of the wires 80 in a wire 78 is soldered to the conductor 54 respectively. After the soldering end 68 is placed, it is placed in the cavity of another plastic injection mold (not shown), and the plastic material forming the protective sleeve 82 is preheated and plasticized, and then injected into the cavity under pressure. To surround the portion of the support portion 58 from the insulative core 52 up to the front end of the wire 78, while the threaded sleeve 76 is slidably retained on the insulative core 52, thus being the desired male connector 90 for use with the female connector 50 described above. Electrical connection.

In order to prevent liquid from penetrating into the joint between the wire 80 and the welding end 68 from the gaps 63 and 81 between the protective cover 82 and the support portion 58 and the electric wire 78, respectively, while avoiding the release of the protective cover 82, it is the same as the female connector 50 described above. A plurality of grooves 61 are spaced apart from each other at the support portion 58. A flange 59 is formed between the adjacent two grooves 61. A plurality of grooves 79 are spaced apart from the front end of the wire 78 so as to be covered by the protective cover 82 on the support portion. When the front end of the 58 and the electric wire 78 is used, a waterproof and tight joint effect can be produced between the contact faces of the two.

It should be noted that the nut 40 on the female connector 50 and the threaded sleeve 76 on the male connector 90 are intended to be illustrative and illustrative. Other designs that can lock the female connector 50 and the male connector 90 can also be used without the nut 40. And the limitation of the threaded sleeve 76.

Moreover, the male connector of the waterproof connector generally has two types, one is a wire end male connector as shown in the eighth figure, and the other is a plate end male connector. The board end male connector is basically divided into two types according to the connection object thereof, and one type is locked in the electronic device. The outer casing is electrically connected to the female connector through the electric wire, and the other end is electrically connected to the female connector and the circuit board of the electronic device.
