[0045] like Figures 11-19As shown, when assembling the connector 100, the positioning shell 34 of the housing 30 is fitted onto the positioning part 28 of the core 20. Specifically, the tongue 22 is inserted into the second inner cavity 345 from the side of the positioning shell 34 away from the stop ring 37 until the positioning sleeve 343 is fitted onto the positioning part 28, so that the positioning sleeve 343 is welded and fixed to the connecting strip 27. The side of the guide tube 50 with the abutment platform 57 is inserted into the positioning groove 322 of the plug shell 32, so that the plug shell 32 and the guide tube 50 are welded and fixed. Specifically, the plug shell 32 and the guide tube 50 are fixedly connected by spot soldering into the first welding hole 324. The second groove 2854 is filled with sealant, so that the sealant fills the first groove 2852 and the second groove 2854, so as to form a first sealing element 60 in the adhesive groove 285, so that the first sealing element 60 seals the gap between the positioning shell 34 and the positioning part 28. The second seal 80 is sealed onto the guide sleeve 50, and the second seal 80 is sealed against the stop ring 37, so that the second seal 80 seals the gap between the plug shell 32 and the guide sleeve 50; the first support shell 72 is fitted onto the positioning block 26 and the plug shell 32, the positioning block 26 and the plug shell 32 are housed in the positioning space 726, so that the abutment frame 720 is welded and fixed to the plug shell 32, specifically, the plug shell 32 and the abutment frame 720 are fixedly connected by spot welding to the second welding hole 728; the second support shell 75 is attached to the surface of the plug shell 32 away from the first support shell 72, so that the two second lugs 754 of the second support shell 75 are respectively attached to the two first lugs 725 of the first support shell 72, and the second support shell 75 is welded to the plug shell 32, specifically, the second support shell 75 and the plug shell 32 are fixedly connected by spot welding to the third welding hole 755. Understandably, the first seal 60 and the second seal 80 can be made by methods such as, but not limited to, injection, application, or bonding.

[0046] In this application, the positioning shell 34 of the connector 100 is sleeved on the rubber core 20 and spot-welded together, and the guide tube 50 is inserted into the positioning groove 322 of the insertion shell 32 and spot-welded together, resulting in good connection strength of the connector 100. Secondly, since the first sealing member 60 seals the gap between the positioning shell 34 and the positioning part 28, and the second sealing member 80 seals the gap between the guide tube 50 and the insertion shell 32, the sealing effect of the connector 100 is better. In addition, since the sealing strip 62 of the first sealing member 60 is located in the second inner cavity 345 of the positioning shell 34, the space occupied by the first sealing member 60 in the insertion and removal direction of the connector 100 is reduced. This not only makes the positioning of the first sealing member 60 more stable and enhances the sealing effect, but also reduces the thickness of the first sealing member 60 in the insertion and removal direction of the connector 100, thereby reducing the insertion and removal direction of the entire connector 100.

[0047] like Figure 20As shown, the specific structure of the connector 100a in the second embodiment of this utility model is similar to that of the connector 100 in the first embodiment, except that the position of the receiving groove 342 on the housing 30 of the connector 100a in the second embodiment is different from that of the receiving groove 342 on the housing 30 of the connector 100 in the first embodiment. Specifically, in the second embodiment, a receiving groove 342 is provided at the connection between the plug shell 32 and the positioning shell 34. That is, a receiving groove 342 is provided at the connection between the side of the connecting part 344 away from the positioning sleeve 343 and the plug shell 32. The receiving groove 342 surrounds the circumference of the plug shell 32 and communicates with the plug groove 340. In this embodiment, the intersection of the connecting part 344 and the plug shell 32 is recessed towards the side away from the plug groove 340 to form a receiving groove 342 surrounding the positioning sleeve 343. If dust or other foreign objects accumulate on the inner surface of the connector housing 32, during the mating process between the connector 100a and the socket to be mated, the dust or other foreign objects will be pushed into the storage groove 342 to avoid obstruction by the dust or other foreign objects, thus ensuring that the connector 100a is properly mated.

[0048] like Figure 21 As shown, the specific structure of the connector 100b in the third embodiment of this utility model is similar to that of the connector 100 in the first embodiment, except that the receiving groove 342 on the housing 30 of the connector 100b in the third embodiment is an additional receiving groove 342 on the basis of the housing 30 in the first embodiment. Specifically, in the third embodiment, a receiving groove 342 is provided at the connection between the positioning sleeve 343 and the connecting part 344, and another receiving groove 342 is provided at the connection between the connecting part 344 and the plug shell 32, that is, the housing 30 is provided with two parallel receiving grooves 342 spaced apart from each other.

The circuit board 301 is electrically connected to the display screen 303, the battery 305, and the connector 100. The battery 305 supplies power to the circuit board 301 and the display screen 303. A charging port 307 is provided on the outer peripheral wall of the housing 302, and the connector 100 is accommodated in the charging port 307. In this embodiment, the charging port 307 is located on the end wall of the housing 302. In other embodiments, the charging port 307 may be located on, but is not limited to, a side wall or a rear wall.

[0050] like Figures 11-12 and Figure 22 As shown, the first soldering end 242 of the metal terminal 24 of the connector 100's core 20 and the second soldering end 272 of the metal connecting strip 27 are respectively soldered to the corresponding pads on the circuit board 301, and spot-welded in the first connecting hole 7252 of the first lug 725 and the second connecting hole 7542 of the second lug 754. The positioning post 727 is positioned in the positioning hole of the circuit board 301, so that the connector 100 is stably fixed to the circuit board 301, and the connector 100 is electrically connected to the circuit board 301. The electronic device 300 may be, but is not limited to, a smartphone, laptop, tablet, digital device, monitor, or audio device.

[0051] In this application, the electronic device 300 has a plug-in groove 340 formed between the plug-in housing 32 and the positioning housing 34, and the inner surface of the plug-in groove 340 is provided with at least one receiving groove 342. If dust or other foreign objects accumulate on the inner surface of the plug-in housing 32, during the insertion process of the connector 100 and the socket to be plugged in, the dust or other foreign objects are pushed into the receiving groove 342 to avoid obstruction by dust or other foreign objects, thus ensuring that the connector 100 is properly inserted. Secondly, the positioning housing 34 and the core 20 are spot-welded together to guide the insertion. The cylinder 50 and the plug shell 32 are spot welded together, and the connector 100 is welded to the circuit board 301, which makes the connection strength of the connector 100 good. In addition, the first sealing element 60 seals the gap between the rubber core 20 and the positioning shell 34, and the second sealing element 80 seals the gap between the guide cylinder 50 and the plug shell 32, which makes the sealing effect of the connector 100 better. Furthermore, the space occupied by the first sealing element 60 in the insertion and extraction direction of the connector 100 is reduced, which helps to reduce the size of the connector 100 in the insertion and extraction direction.

[0052] The above are the implementation methods of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications are also considered to be within the protection scope of the present utility model.
