[0034] Please continue reading Figure 2 , Figure 3 , Figure 6 As shown, the connector A includes a first terminal group 21, a second terminal group 22, a partition 23 placed between the first terminal group 21 and the second terminal group 22 in the up and down direction, and an insulating body that fixes the first terminal group 21, the second terminal group 22 and the partition 23 as a whole.

[0035] The first terminal group 21 and the second terminal group 22 each include a plurality of independent conductive terminals, each of which includes a contact portion 211 with one side exposed to the outside, an embedded portion 212 completely wrapped by the insulating body, and a welding foot 213 extending backward out of the insulating body. The partition 23 includes a plate body 231 and a lateral extension portion 232 extending from the lateral sides of the rear end of the plate body 231 to the lateral outside. The first terminal group 21 and the second terminal group 22 include a ground terminal, a pair of signal terminals (optional), a power terminal, a plurality of signal terminals, a power terminal, a pair of signal terminals (optional), and a ground terminal in the lateral direction. The partition 23 is set as two independent plates on both sides of the lateral direction. The plate body 231 is located between the ground terminals of the first terminal group 21 and the second terminal group 22. There is no partition between the two power terminals of the first terminal group 21 and the second terminal group 22 and the plurality of signal terminals therebetween. The partition 23 may be in contact with the ground terminal or not.

[0036] The insulating body includes a first insulator 30 that first molds and fixes the first terminal group 21, the second terminal group 22 and the partition 23 together, and a second insulator 40 that wraps at least a portion of the first insulator 30. The first insulator 30 includes a clamping portion 31 that is inserted into the front hole 121 of the assembly hole 12, a pre-holding portion 33 that extends forward from the clamping portion 31 and holds the first terminal group 21, the contact portion 22 of the second terminal group 22, and the partition 23 as a whole, a limiting portion 32 formed at the rear end of the clamping portion 31, and an independent tail portion 34 that is located at the rear end of the limiting portion 32 and is separated from the limiting portion 32. A gap 35 is formed between the independent tail portion 34 and the limiting portion 32, which is connected only by the first terminal group 21, the second terminal group 22 and the partition. When the first insulator 30 is injection molded, the first terminal group 21, the second terminal group 22 and the partition 23 are connected to a plurality of strips at the front and rear. After the first insulator 30 is injection molded, part of the strips need to be cut off, and the strips at the front end of the first and second terminal groups 21, 22 need to be cut off, so that the front end of the first and second terminal groups 21, 22 is exposed to the outside and needs to be covered by the second insulator 40. The lateral extension 232 of the partition 23 extends out of the outside of the first insulator 30 in the lateral direction. The upper side of the independent tail 34 is provided with a glue injection port 341 connected to the gap 35, and the glue injection port 341 extends in the front-to-back direction and is open at the upper side.

[0037] The second insulator 40 includes another clamping portion 41 located in front of the clamping portion 31 of the first insulator 30, a transition portion 42 extending forward from the clamping portion 41, a wrapping portion 43 extending forward from the transition portion 42, and an embedded tail portion 44 partially filling the independent tail portion 34 of the first insulator 30. The outer diameter of the clamping portion 31 of the first insulator 30 is consistent with the outer diameter of the clamping portion 41 of the second insulator 40, and is located in the front-to-back direction. The outer surfaces of the clamping portions 31 and 41 are provided with limiting convex strips 311 and 411, and the outer diameters of the clamping portions 31 and 41 are smaller than the outer diameters of the limiting portions 32. The outer diameters of the clamping portions 31 and 41 are larger than the outer diameters of the transition portion 42. The second insulator 40 wraps and protects the front edges of the contact portions 211 of the first and second terminal groups 21 and 22, and fills the remaining areas that need to be filled.

[0038] The clamping parts 31, 41 of the first insulator 30 and the second insulator 40 are combined into one clamping part, and the clamping parts 31, 41 are fixed in the front hole 121 of the assembly hole 12 of the fixed shell 10 by being sleeved. In one embodiment, the outer diameter of the clamping part 31 of the first insulator 30 is smaller than the outer diameter of the clamping part 41 of the second insulator 40, and the clamping part 41 of the second insulator 40 wraps the clamping part of the first insulator 30 in the outer layer to achieve better bonding. In one embodiment, the first insulator 30 is not provided with the clamping part 31, and the clamping part is formed by the second insulator 40, but the clamping part 41 is wrapped outside the first insulator 30.

[0039] Key References Figure 3 , Figure 5 , Figure 6As shown, the plug connector A of the socket of the present application is inserted into the assembly hole 12 of the fixed shell 10 from the back to the front. At this time, at least part of the clamping portion 41 of the second insulator 40 is fixed and clamped between the inner wall surfaces of the front hole 121, and the clamping portion 31 of the first insulator 30 is also clamped and fixed by the inner wall surface of the front hole 121. The limiting end surface 321 of the limiting portion 32 of the insulating body abuts against the abutting step 125 at the junction of the front hole 121 and the rear hole 122 to limit the plug connector A from moving forward. The limiting portion 32 is fixed between the inner wall surfaces of the rear hole 122. The gap 35 is located in the bonding hole 123 at the rear side of the rear hole 122. The cover 14 covers the upper side of the glue injection port 341 to close the open side of the glue injection port 341. Glue is injected into the gap 35 from the glue injection port 341. The glue is bonded to the conductive terminal, the partition 23 and the inner wall surface of the bonding hole 123 in the gap 35. At the same time, the step surface 126 is bonded by the glue. After the glue is cured, the glue block 50 is formed. The glue block 50 realizes the sealing of the front and rear sides. The lateral extension 232 of the partition 23 that protrudes laterally from the independent tail 34 of the first insulator 30 extends from the gap 15 between the cover 14 and the ear 16 to the side surface of the ear 16. The lateral extension 232 and the ear 16 are fixed together by spot welding. In this way, the plug-in connector A is fixed in the fixed shell 10 to prevent it from being withdrawn.

[0040] The insulating body is a combination of the first insulator 30 and the second insulator 40. The insulating body includes a clamping portion formed by the clamping portions 31 and 41, a transition portion 42 formed by extending forward, and a docking tongue portion formed by the wrapping portion 43 being combined with the outside of the pre-holding portion 33. The insulating body is held in the fixed shell 10. The docking tongue portion needs to withstand a large plugging and unplugging force. The second insulator 40 is provided with a clamping portion 41 clamped in the assembly hole 12 of the fixed shell 10, which can effectively increase the strength of the docking tongue portion. The contact portions 21 of the first terminal group 21 and the second terminal group 22 are respectively exposed on the upper and lower surfaces of the docking tongue portion.

[0041] Please refer to Figures 7 to 9The present application also includes an electronic device, which includes a device housing 70 with an insertion hole formed therethrough, a circuit board and the aforementioned socket, wherein the socket is welded on the circuit board and partially inserted into the insertion hole 72. Specifically, the transition portion 42 and the docking tongue portion of the socket are completely exposed to the front side of the fixed shell 10 and inserted into a device housing 70 of an electronic device, wherein the device housing 70 may be a mobile phone frame, etc. The device housing 70 includes a shell 71 and an insertion hole 72 that penetrates the shell 71. A crimping end face 73 is formed on the rear end face of the insertion hole 72, wherein the crimping end face 73 may be a plane or provided with a groove 731.

[0042] The socket is inserted into the insertion hole 72 of the device housing 70 from the back to the front, wherein the docking tongue and the transition portion 42 are located in the insertion hole 72, and the fixed shell 10 is crimped to the crimping end surface 73 of the rear peripheral edge of the insertion hole 72 through the waterproof ring 60 to achieve waterproofing. With such a design, it is possible to avoid inserting the metal shell of the socket into the insertion hole 72 of the device housing 70, and directly use the device housing 70 as the protective shell of the docking tongue, and at the same time achieve waterproofing by longitudinal crimping, which effectively reduces the product size.

[0043] The waterproof ring 60 includes an insertion portion 61 inserted into the mounting groove 131 of the fixed shell 10 and an exposed portion 62 integral with the insertion portion 61 and located outside the mounting groove 131. The exposed portion 62 includes an outer package portion 63 covering the front end surface of the outer wall 133 of the annular groove 13 and a crimping end 64 located at the front end of the exposed portion 62 for crimping the crimping end surface 73 of the device housing 70. The thickness of the crimping end 64 is less than the thickness of the exposed portion 63. When a groove 74 is provided on the crimping end surface 73, the crimping end 64 is pressed into the groove 74 to prevent water from entering.

[0044] The socket of the present application is provided with a fixed shell 10 that does not wrap the docking tongue, so that the docking tongue is directly surrounded and protected by the insertion hole 72 of the device shell 70 of the electronic device. At the same time, an annular groove 13 is provided on the front end face 17 of the fixed shell 10 to accommodate the waterproof ring 60, so that the waterproof ring 60 is longitudinally crimped on the crimping end face 73 behind the insertion hole 72 of the device shell 70 to achieve waterproofing, thereby minimizing the size of the socket.

[0045] The socket of the present application is provided with a clamping portion 41 at least partially clamped in the assembly hole 12 of the fixing shell 10 through the second insulator 40, so that the plastic at the docking tongue portion is supported by the fixing shell 10 without being easily broken or cracked.

[0046] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
