Wherein the main structure comprises a headset slot 121, a fixing structure 122 for fixing other components of the mobile phone, and a headset contact slot 123; the metal spring plate includes contacts 111a, 112a, 113a, etc. respectively connected to left and right sound channels and microphones on the headset, and pins 111b, 112b, 113b, etc. corresponding to the other end of the spring plate 110 are used as connection pads to the main board of the mobile phone. In the conventional headset assembly 10, the main structures 120 and 110 are integrally assembled by means of a plug-in snap-fit, and the assembly gap between 123 and 111a is the passage for moisture to enter the interior of the handset.

Compared with the prior art, because the elastic component 240 is arranged inside the housing of the port in the embodiment, when a plug is inserted into the housing under the action of external force, the elastic component 240 contracts to expose the conductive terminals, so that the plug is conducted with the conductive terminals, and the elastic component 240 rebounds to the initial position when the plug is pulled out of the port, so that the interior of the housing of the port is sealed, and the waterproof function of the port is realized.

The material of the elastic component 240 is thermoplastic rubber (TPR), but is not limited to this elastic material, and other materials with the same property are also possible.

The housing of the port of this embodiment preferably includes a first component 220 and a second component 230 that are detachably connected, and the elastic component 240 penetrates through the first component 220 and the second component 230.

Further, the elastic component 240 includes a main body portion 241, a transition portion 243, and a limiting portion 244 connected in sequence; the first assembly 220 includes a first body having a receiving hole 221, the receiving hole 221 being used for receiving the main body portion 241 of the elastic assembly 240; the second assembly 230 comprises a second body, the second body has a transition hole 232, a slot 233 communicated with the transition hole 232 is arranged on a first side wall of the second body, and a limit slot 231 is arranged at one end of the second body, which is far away from the first assembly 220; wherein the transition portion 243 of the elastic component 240 can be placed in the transition hole 232 through the slot 233; the limiting groove 231 is matched with the limiting part 244.

Specifically, fig. 4 is a perspective view of the elastic member 240 in a memory shape, and the elastic member will always return to the memory shape if the elastic member is removed by an external force after being deformed by the external force. The main body 241 of the elastic element 240 is fitted into the receiving hole 221 of the first element 220 shown in fig. 7. When the earphone is not inserted, the receiving hole 221 of the first component 220 is blocked by the body portion 241 of the elastic component 240, so as to prevent external moisture from entering into the receiving hole 221. An outer smooth surface 2411 is arranged at one end, away from the limiting part 244, of the main body part 241 of the elastic component 240, and the outer smooth surface is outside the accommodating hole 221, so that appearance processing can be performed according to requirements of shapes, color matching and the like of actual products. The elastic member 240 further includes a buffer portion 242 connected between the main body portion 241 and the transition portion 243, the buffer portion 242 preventing the elastic body from being pushed out when the plug is inserted; the transition portion 243 of the elastic member 240 deforms under force when the plug is inserted, releasing the pressed portion to the other side; the elastic body stopper 244 fixes the elastic member 240 to the second member 230 without loosening.

Fig. 5 shows a specific structure of the second assembly 230, which includes not only the second body, which has the transition hole 232, the slot 233 and the limiting groove 231, but also a limiting baffle 234 connected to the second body, wherein the limiting baffle 234 is disposed opposite to the transition hole 232 and is used for blocking the limiting portion 244 when an external force is applied to the main body portion 241. That is, the limiting groove 231 and the limiting baffle 234 in the second assembly 230 are limiting structures. At this time, after the plug is inserted into the port, the elastic component 240 deforms under compression, and the main body 241 of the elastic cylinder rotates into the area limited by the limit groove 231 and the limit baffle 234 through the transition hole 232, and after the plug is pulled out, the elastic component 240 rebounds to the original shape through memory and plugs the accommodating hole 221 of the first component 220; the slot 233 is used for inserting and assembling the transition portion 243 of the elastic member 240. Fig. 6 is a schematic diagram of the assembled elastic component 240 and the second component 230. Further, the first component 220 further includes a protrusion 222 disposed on the first body; the protrusion 222 is engaged with the slot 233 of the second body when the first module 220 is connected to the second module 230, so that the first module 220 and the second module 230 are tightly connected, and moisture is prevented from entering the inside as much as possible.
