To avoid unnecessary repetition, various possible combination manners of the specific technical features / embodiments in the present utility model will not be described separately.

[0029] The present utility model provides an internal and external waterproof headphone socket connector. Please refer to Figures 1 to 9, the internal and external waterproof headphone socket connector 100 includes an insulating body 1, a terminal group 2 provided on the insulating body 1, and a bottom cover 3. Among them, a headphone hole 11 for inserting and connecting an external headphone plug is provided on the top surface of the insulating body 1 to realize the insertion and connection of the external headphone plug; a terminal hole 12 adjacent to the headphone hole 11 and for inserting and assembling the terminal group 2 is provided on the bottom surface of the insulating body 1 to fix the terminal 21 and play a role in supporting and limiting the main body. The terminal group 2 includes a plurality of terminals 21, and each terminal 21 includes a fixing portion 211, a conductive portion 212, and a conduction portion 213. The bottom end of the fixing portion 211 is connected to the conductive portion 212, and the top end is connected to the conduction portion 213. And an electrophoretic insulating layer is provided on the surface of the fixing portion 211. When there is accumulated water inside, the electrophoretic insulating layer can prevent the terminals 21 from short-circuiting due to the accumulated liquid, improve the reliability, and realize internal waterproofing; and the conductive portion 212 is used for connecting and conducting electricity with an external circuit board; the conduction portion 213 extends from the terminal hole 12 into the headphone hole 11 to abut and conduct with the headphone plug. The bottom cover 3 is inserted into the terminal hole 12 and is arranged close to the bottom surface of the insulating body 1 to seal the opening of the terminal hole 12. And a glue groove 41 is formed between the bottom cover 3 and the hole wall of the terminal hole 12. The sealant 4 is provided in the glue groove 41 and covers the gap between the bottom cover 3 and the insulating body 1. By assembling the bottom cover 3 and then applying glue, the exposed position of the terminal 21 is isolated and sealed, effectively preventing water droplets and the like from leaking in, thereby realizing external waterproofing. Therefore, the present utility model can achieve the internal and external waterproofing of the internal and external waterproof headphone socket connector 100, greatly improving the waterproof performance and meeting the user's usage requirements.

[0030] It can be understood that when human sweat or conductive liquid flows from the opening of the headphone hole to the bottom of the internal and external waterproof headphone socket connector and forms accumulated liquid, it is very likely that the terminals of the traditional headphone socket connector will short-circuit. And the present utility model can make the local area of the terminal 21 electrophoretically insulated by adopting an electroplating process. Therefore, when human sweat or conductive liquid forms accumulated liquid, the terminals 21 of the internal and external waterproof headphone socket connector 100 will not short-circuit and can still maintain normal operation. The internal and external waterproof headphone socket connector 100 of the present utility model has an internal protection function, which can effectively avoid the problem that the terminals 21 short-circuit due to the accumulated liquid conducting electricity and cause the function to fail. Moreover, after the internal and external waterproof headphone socket connector 100 of the present utility model inserts and installs the terminal 21 from the bottom surface and assembles the bottom cover 3, the sealant 4 is used to seal the pores, so that the product has an external waterproof function, further improving the waterproof performance of the internal and external waterproof headphone socket connector 100.

[0031] It should be noted that an electrophoresis insulation layer is provided on the surface of the fixing part 211. Specifically, as long as the use of the terminal 21 is not affected, except for the parts used for connecting to the circuit (conductive part 212) and the parts used for abutting against the headphone plug (conductive part 213), the outer surfaces of other parts of the terminal 21 can be provided with an electrophoresis insulation layer to improve the insulation effect and ensure the safety and reliability of the internal and external waterproof headphone socket connector 100.

[0032] It can be understood that the specific type of the sealant 4 is not limited in the present invention, as long as it can play a sealing role. For example, the sealant 4 can be a thermosetting adhesive, which can be cured by baking and is convenient for dispensing. Moreover, the technical solution provided by the present invention can be applied not only to the internal and external waterproof headphone socket connector 100, but also to other connectors with similar assembly structures.

[0033] Preferably, please refer to Figures 1 to 3 , the bottom cover 3 can be provided with a plug hole 31 for the terminal 21 to be inserted, so as to position the bottom cover 3 and improve the connection firmness.
