[0048] A plurality of conductive pins 26 spaced apart from each other are provided in the plug cavity 231 of the plug rubber core 20. Specifically, a plurality of positioning holes 253 spaced apart from each other are provided on the connection surface 251 of the positioning plate 25. The positioning holes 253 are connected to the plug cavity 231. The plurality of conductive pins 26 are respectively positioned in the plurality of positioning holes 253. One end of the conductive pin 26 is accommodated in the plug cavity 231, and the other end of the conductive pin 26 extends out of the connection surface 251.

[0049] In other embodiments, the waterproof groove 22 passes through the entire plug rubber core 20, that is, the connecting plate 255 is an independent plate body, and the connecting plate 255 is connected to the side of the rubber core body 23 facing the circuit board 40 through the positioning column 256, and the gap between the connecting plate 255 and the rubber core body 23 forms the waterproof groove 22; that is, the connecting plate 255 is close to the positioning plate 25, and there is a gap between the connecting plate 255 and the positioning plate 25, and the connecting plate 255 is connected to the positioning plate 25 through the positioning column 256, and the gap between the positioning plate 25 and the connecting plate 255 forms the waterproof groove 22.

[0050] Optionally, the rubber core body 23 is a plug-in rubber cylinder that is asymmetrical in both the top and bottom and the left and right directions. Therefore, the plug rubber core 20 can not only achieve structural foolproofing, but also play a visual identification role. In this embodiment, the rubber core body 23 is a trapezoidal body, one end of which is connected to the side of the positioning plate 25 away from the connecting plate 255, and the plug-in cavity 231 is opened on the end face of the trapezoidal body away from the positioning plate 25.

[0051] The plug rubber core 20 is generally limited in space reserved by customers. The base that matches the plug rubber core 20 is an existing product, and the base has certain limitations in thickness, structure and height. In order to match the existing base, the part of the existing rubber core used to position multiple conductive pins cannot meet the uniform design, and the thickness of this part is uneven, with the thinnest part only between 0.3mm and 0.35mm. When using nylon or other materials for injection molding, there may be defects such as material shortage and shrinkage. Specifically, the use of nylon material to inject into the rubber core not only fails to meet the requirements of good appearance and good performance, but also may cause material shortage or shrinkage, which will also have different degrees of impact on the waterproofness of the product; the poor appearance of the rubber core will affect customers' choice of the product, and the poor performance will affect customers' normal use; the plug rubber core 20 is made of LCP material. After many verifications, on the basis of the unchanged structure of the plug rubber core 20, the plug rubber core 20 made of LCP material injection molding can avoid the plug rubber core 20 from having material shortage, shrinkage and other undesirable phenomena, which can not only make the plug rubber core 20 have a good appearance and meet customers' low height requirements, but also improve the overall waterproofness of the plug rubber core 20.

[0052] like Figure 2 and Figure 6-Figure 7As shown, the circuit board 40 includes a first welding portion 42, a second welding portion 44 and a strip-shaped connecting portion 46. The first welding portion 42 and the second welding portion 44 are respectively arranged at opposite ends of the connecting portion 46; the opposite ends of the first welding portion 42 are respectively provided with positioning grooves 41, and the two clamping columns 257 can be respectively positioned in the two positioning grooves 41. The first welding portion 42 is connected to the plug rubber core 20. Specifically, the first welding portion 42 is used to weld the conductive pins 26 of the plug rubber core 20; the second welding portion 44 is used to weld the wire, so that the connection between the wire and the circuit board 40 is far away from the first welding portion 42. The first welding portion 42 and the second welding portion 44 are both roughly rectangular plates. The width of the first welding portion 42 is greater than the width of the second welding portion 44, and the width of the connecting portion 46 is less than the width of the second welding portion 44. In this embodiment, a plurality of vias 420 spaced apart from each other are opened on the first welding portion 42, and a plurality of conductive pins 26 are respectively inserted into the plurality of vias 420, and the conductive pins 26 are electrically connected to the circuit board 40 through the corresponding vias 420. Specifically, eight vias 420 are provided on the first welding portion 42, and eight conductive pins 26 are provided on the plug rubber core 20 and respectively plugged into the eight vias 420.

The width of the first welding portion 42> the width of the second welding portion 44> the width of the connecting portion 46, which is more conducive to gripping, rubber encapsulation and waterproofing. The first welding portion 42 includes a first welding area 422 facing the plug rubber core 20 and a second welding area 424 connected to the first welding area 422, one end of the connecting portion 46 is connected to one end of the second welding area 424 away from the first welding area 422, and the two positioning grooves 41 are respectively provided on opposite sides of the first welding area 422. The shape of the first welding area 422 is consistent with the side of the plug rubber core 20 facing the circuit board 40, that is, the shape of the first welding area 422 is consistent with the shape of the connecting surface 251 of the plug rubber core 20; the width of the side of the second welding area 424 close to the first welding area 422 is greater than the width of the side of the second welding area 424 away from the first welding area 422; in this embodiment, the width of the second welding area 424 gradually decreases from the first welding portion 42 to the connecting portion 46.

[0053] like Figure 2 and Figure 6-Figure 7As shown, optionally, a plurality of through slots 462 are provided on the connection portion 46, and the plurality of through slots 462 are arranged along the length direction of the connection portion 46, and the first rubber package 61 fills the through slots 462. In this embodiment, two through slots 462 are provided on the connection portion 46, and the two through slots 462 are arranged at intervals from each other along the length direction of the connection portion 46, wherein one end of one through slot 462 extends to the second welding area 424, and the other end extends to the middle of the connection portion 46. The width of the connection between the second welding portion 44 and the connection portion 46 gradually decreases from the second welding portion 44 to the connection portion 46, and a strip groove 442 is provided on the second welding portion 44, and the strip groove 442 passes through the opposite sides of the second welding portion 44, and the length direction of the strip groove 442 can be parallel to the length direction of the connection portion 46, and can also be perpendicular to the length direction of the connection portion 46. In this embodiment, two strip grooves 442 are provided on the second welding portion 44, wherein the length direction of one strip groove 442 is parallel to the length direction of the connecting portion 46, and the length direction of the other strip groove 442 is perpendicular to the length direction of the connecting portion 46; one of the strip grooves 442 is close to the connecting portion 46 and one end of the strip groove 442 extends to the connecting portion 46, and the other strip groove 442 is away from the connecting portion 46. Since the through groove 462 is provided on the connecting portion 46 and the strip groove 442 is provided on the second welding portion 44, the pressure during the encapsulation process in the injection molding machine can be dispersed, so that the first encapsulation member 61 can completely wrap the circuit board 40.

[0054] like Figure 2 and Figure 10-11 As shown, the first rubber package 61 includes a first rubber package part 612 for wrapping the first welding part 42, a second rubber package part 614 for wrapping the second welding part 44, and a hand-held part 616 for wrapping the connecting part 46. The width of the first rubber package part 612 is greater than the width of the second rubber package part 614, and the width of the second rubber package part 614 is greater than the width of the hand-held part 616; that is, the first rubber package 61 wraps the first welding part 42 to form the first rubber package part 612, the first rubber package 61 wraps the second welding part 44 to form the second rubber package part 614, and the first rubber package 61 wraps the connecting part 46 to form the hand-held part 616. In this embodiment, the first rubber package part 612 is filled into the waterproof groove 22, and the first rubber package part 612 wraps the positioning plate 25. The shape of the first welding part 42 is similar to the side of the plug rubber core 20 facing the circuit board 40, which can facilitate the injection molding of the first rubber package 61. Optionally, the thickness of the first rubber-wrapped portion 612 is less than the thickness of the hand-held portion 616, and the thickness of the second rubber-wrapped portion 614 is greater than the thickness of the hand-held portion 616. Optionally, the second rubber-wrapped portion 614 can be provided in a stepped shape, which not only saves materials, facilitates rubber-wrapping, but also is not easy to break. In other embodiments, the thickness of the first rubber-wrapped portion 612 is equal to the thickness of the hand-held portion 616, and the thickness of the second rubber-wrapped portion 614 is greater than the thickness of the first rubber-wrapped portion 612.

[0055] In this embodiment, the shape of the first rubber-wrapped portion 612 is consistent with the shape of the first welding portion 42, that is, the end of the first rubber-wrapped portion 612 away from the hand-held portion 616 is rectangular, and the end of the first rubber-wrapped portion 612 close to the hand-held portion 616 is inverted triangular, so that the first rubber-wrapped portion 612 can wrap the first welding portion 42 and the plug rubber core 20 connected to the first welding portion; secondly, the inverted triangular portion of the first rubber-wrapped portion 612 is easy to connect the narrow and long shape of the hand-held portion 616, that is, the opposite sides of the inverted triangular portion are used to connect the rectangular portion of the first rubber-wrapped portion 612 and the hand-held portion 616, thereby playing a transition role and enhancing the strength of the first rubber-wrapped member 61. In addition, the first rubber-wrapped member 61 can wrap the circuit board 40 and the connection between the plug rubber core 20 and the circuit board 40 tightly, and when conducting a waterproof performance test, water will not enter the product through the gap, thereby improving the waterproof effect.

[0056] Optionally, the second rubber-coated portion 614 is used to wrap the second welding portion 44 and the wire connected to the second welding portion 44. The second rubber-coated portion 614 has a large thickness, which can make the connection between the wire and the circuit board 40 more secure and has a good waterproof effect. Since the wire is welded to the second welding portion 44, the wire is far away from the first welding portion 42. The second rubber-coated portion 614 wraps the second welding portion 44 and the wire. The second rubber-coated portion 614 is located at an end away from the plug rubber core 20, which can reduce the overall thickness of the first rubber-coated portion 612 to be suitable for low height and narrow space; the radial size of the hand-held portion 616 is small, so as to save the space for injection molding of the first rubber-coated part 61, fundamentally avoiding the situation that the first rubber-coated part 61 cannot cover the glue, thereby increasing the yield and efficiency of the first rubber-coated part 61.

[0057] like Figure 1-Figure 2 and Fig.13As shown, the second rubber-wrapped part 63 includes a first outer rubber-wrapped part 632 for wrapping the first rubber-wrapped part 612, a second outer rubber-wrapped part 634 for wrapping the second rubber-wrapped part 614, and a middle rubber-wrapped part 636 for wrapping the hand-held part 616, wherein the width of the middle rubber-wrapped part 636 is smaller than the width of the second outer rubber-wrapped part 634, and the width of the second outer rubber-wrapped part 634 is smaller than the width of the first outer rubber-wrapped part 632. Optionally, a first stop convex portion 6321 and a second stop convex portion 6323 are provided on the side of the second rubber covering member 63 away from the plug rubber core 20, and the first stop convex portion 6321 and the second stop convex portion 6323 are spaced from each other; specifically, the first stop convex portion 6321 and the second stop convex portion 6323 are both convex strips, and the first stop convex portion 6321 and the second stop convex portion 6323 are both provided on the side of the first outer rubber covering portion 632 away from the plug rubber core 20, the first stop convex portion 6321 is away from one end of the middle rubber covering portion 636, and the second stop convex portion 6323 is close to one end of the middle rubber covering portion 636. A positioning space 6325 is formed between the first stop convex portion 6321 and the second stop convex portion 6323 on the side of the first outer rubber covering portion 632 away from the plug rubber core 20. Optionally, the second rubber-wrapped member 63 further includes a wire-wrapped portion 637, which is disposed at one end of the second outer rubber-wrapped portion 634 away from the middle rubber-wrapped portion 636. The second outer rubber-wrapped portion 634 and the wire-wrapped portion 637 are used to wrap the wire 90, which can prevent the second rubber-wrapped member 63 from shrinking. The second rubber-wrapped member 63 wraps the first rubber-wrapped member 61 with a uniform wall thickness, which facilitates the molding of the second rubber-wrapped member 63.

[0058] It is understandable that the shapes of the first rubber-coated member 61 and the second rubber-coated member 63 can be designed as needed, such as the shapes of the first rubber-coated member 61 and the second rubber-coated member 63 can be but not limited to irregular shapes. The rubber-coated shell 60 can be made of but not limited to nylon or LCP materials.

[0059] Please also read Figure 1-Figure 2 and Figure 8-Figure 12 , the manufacturing process of the waterproof connector plug 100 is as follows:

[0060] The wire material 90 is cut, and the wire skin of the conductive wire of the wire material 90 is stripped, and the stripped conductive wire is tinned, and then the wire material 90 is welded to the second welding portion 44 of the circuit board 40;

[0061] The circuit board 40 with the wire 90 is welded to the terminal of the plug rubber core 20. Specifically, the plurality of conductive pins 26 of the plug rubber core 20 are respectively inserted into the plurality of via holes 420 of the first welding portion 42, and the conductive pins 26 are welded to the circuit board 40.

[0062] The welded plug rubber core 20 and the circuit board 40 are placed in an injection molding machine for rubber coating. Specifically, the first rubber coating member 61 coats the first welding portion 42, the connecting plate 255 and the positioning plate 25 to form a first rubber coating portion 612. At this time, the colloid is filled in the waterproof groove 22; the first rubber coating member 61 coats the second welding portion 44 and the wire 90 welded on the second welding portion 44 to form a second rubber coating portion 614, and the colloid is filled in the strip groove 442; the first rubber coating member 61 coats the connecting portion 46 to form a hand-held portion 616, and the colloid is filled in the through groove 462; the second rubber coating member 63 coats the first rubber coating member 61 to form a first outer rubber coating portion 632, a second outer rubber coating portion 634 and a middle rubber coating portion 636, and the second rubber coating member 63 coats one end of the wire 90 connected to the circuit board 40 to form a wire coating portion 637. Since the connecting portion 46 is provided with a through groove 462 and the second welding portion 44 is provided with a strip groove 442 , the pressure during the encapsulation process in the injection molding machine can be dispersed so that the first encapsulation member can completely wrap the circuit board 40 .

[0063] An automatic glue machine is used to fill the junction of the glue core body 23 and the rubber-encapsulated shell 60 with waterproof glue to form a waterproof rubber ring; Fig.29 The waterproof glue groove 65 is filled with waterproof glue; Fig.31 As shown, waterproof glue is filled in the cavity between the glue groove 65 and the waterproof groove 22 to form a waterproof rubber ring, thereby improving the waterproof effect of the waterproof connector plug.

[0064] The sealing ring 70 is sleeved on the rubber core body 23 , and specifically can be fitted in the rubber groove 235 of the rubber core body 23 . The sealing ring 70 is used to achieve waterproofing when the waterproof connector plug 100 and the connector socket 300 are plugged in.

[0065] Please also read Figure 13-14 The present application also provides a connector, which includes a waterproof connector plug 100 and a connector socket 300, wherein the waterproof connector plug 100 is plugged into the connector socket 300. Specifically, the connector socket 300 includes a seat body 302 and a cover body 304, wherein the cover body 304 is connected to one end of the seat body 302 facing the supporting surface 305 of the waterproof connector plug 100 through a rotating shaft; in this embodiment, a protrusion 306 is provided on opposite sides of one end of the supporting surface 305 of the seat body 302, the cover body 304 is located between the two protrusions 306, and an axial hole 307 is provided on each protrusion 306, and the two axial holes 307 on the two protrusions 306 are coaxial, and a rotating shaft 308 is provided on opposite sides of one end of the cover body 304 located between the two protrusions 306, and the two rotating shafts 308 are coaxial, and the two rotating shafts 308 are rotatably accommodated in the axial holes 307 of the two protrusions 306. A female end insert 309 is disposed in the middle of the supporting surface 305 . A female end rubber core 310 is disposed in the female end insert 309 . A plurality of conductive plug holes 311 are disposed on the female end rubber core 310 .

[0066] When the rubber core 23 is inserted into the female end plug 309, the plurality of conductive pins are respectively inserted into the plurality of conductive plug holes 311, the sealing ring 70 is sealed and clamped between the rubber core 23 and the inner surface of the female end plug 309, and the waterproof rubber ring 80 is sealed and clamped between the seat 302 and the plug rubber core 20; and the thickness of the space between the cover 304 and the supporting surface 305 of the cover 304 is equal to the thickness of the first outer rubber part 632, the cover 304 covers the positioning space 6325, and the first stop convex part 6321 and the second stop convex part 6323 position the cover 304 to prevent the cover 304 from over-pressing the waterproof connector plug 100. When the waterproof connector plug 100 needs to be pulled out from the connector socket 300, since the handle is designed in a bar shape, it is convenient for the user to grasp it, so as to facilitate the pulling out of the waterproof connector plug 100.

[0067] See also Fig.15 The structure of the waterproof connector plug in the second embodiment of the present application is similar to that of the waterproof connector plug in the first embodiment, except that: in the second embodiment, a glue-receiving area 4220 is formed between the side of the first welding portion 42 away from the connecting portion 46 and the connecting surface 251 of the plug rubber core 20. Specifically, the length of the first welding area 422 is less than the length of the connecting surface 251, so that the glue-receiving area 4220 is formed on the side of the first welding area 422 away from the second welding area 424, and the first rubber package can be filled in the glue-receiving area 4220. In order to better meet the waterproof requirements of the waterproof connector plug and allow the inner mold to better wrap the circuit board 40, material reduction optimization is performed on the basis of the circuit board 40 with the groove 462 opened, and the end of the first welding portion 42 away from the connecting portion 46 is overall reduced by 0.5mm-1.0mm; compared with the shape of the first welding portion 42 being consistent with the shape of the connecting plate 255, if the wire is not put in place, there will be a phenomenon that the inner mold cannot wrap the circuit board 40, and the circuit board 40 after material reduction by opening the glue area 4220 can save more space for the inner mold injection molding, thereby better improving the yield of the inner mold injection molding, so that the connection between the circuit board 40 and the plug glue core 20 is more firm and the waterproof effect is better.

[0068] See also Figure 16-Figure 17The structure of the waterproof connector plug in the third embodiment of the present application is similar to that of the waterproof connector plug in the first embodiment, except that: in the third embodiment, a through hole 463 is used on the connection part 46 to replace the through groove 462 on the connection part 46 in the first embodiment; specifically, a plurality of through holes 463 are provided on the connection part 46, and the plurality of through holes 463 are arranged along the length direction of the connection part 46, and the first plastic package fills the through holes 463. Since the through holes 463 are provided on the connection part 46, the pressure during the plastic package in the injection molding machine can be dispersed, so that the first plastic package can completely wrap the circuit board 40. In this embodiment, the plurality of through holes 463 are arranged in a row along the length direction of the connection part 46. In other embodiments, the plurality of through holes 463 are arranged in more than two rows, and the more than two rows of through holes 463 are arranged in a spaced relationship along the width direction of the connection part 46, and each row of through holes 463 is arranged along the length direction of the connection part 46.

[0069] See also Fig.18 The structure of the waterproof connector plug in the fourth embodiment of the present application is similar to that of the waterproof connector plug in the third embodiment, except that: in the fourth embodiment, the length of the first welding area 422 is less than the length of the connecting surface 251, so as to form a glue-containing area 4220 on the side of the first welding area 422 away from the second welding area 424, and the first plastic-encapsulated part is filled in the glue-containing area 4220. Since the area of ​​the first welding area 422 is reduced relative to the area of ​​the connecting surface 251 of the plug plastic core 20, the circuit board 40 can save more space for the injection molding of the first plastic-encapsulated part, so that the first plastic-encapsulated part can completely wrap the circuit board 40, thereby better improving the injection molding yield of the first plastic-encapsulated part; and the connection between the circuit board 40 and the plug plastic core 20 is more firmly connected, and the waterproof effect is better.

[0070] See also Fig.19 The structure of the waterproof connector plug in the fifth embodiment of the present application is similar to that of the waterproof connector plug in the first embodiment, except that the through groove on the connecting portion 46 in the fifth embodiment can be omitted. In other embodiments, the strip groove 442 on the second welding portion 44 can also be omitted. In other embodiments, both the through groove on the connecting portion 46 and the strip groove 442 on the second welding portion 44 are omitted.

[0071] See also Fig. 20 The structure of the waterproof connector plug in the sixth embodiment of the present application is similar to that of the waterproof connector plug in the fifth embodiment, except that: in the sixth embodiment, the length of the first welding area 422 is less than the length of the connecting surface 251, so as to form a glue-containing area 4220 on the side of the first welding area 422 away from the second welding area 424, and the first glue-encapsulating part is filled in the glue-containing area 4220, so as to make the connection between the circuit board 40 and the plug rubber core 20 more firm and achieve better waterproof effect.

[0072] Please also read Figure 21-23 The wire structure of the waterproof connector plug in the seventh embodiment of the present application is similar to that of the waterproof connector plug in the first embodiment, except that the structure of the circuit board 40 in the seventh embodiment is different from that of the circuit board 40a in the first embodiment. The circuit board 40a in the seventh embodiment omits the second welding portion 44 and the connecting portion 46 on the basis of the circuit board 40 in the first embodiment, and the cut wire 90 is welded to the second welding area 424. Two power pin pads 4241 and a signal pin pad 4243 are provided on one side of the second welding area 424, and a plurality of signal pin pads 4243 are provided on the other opposite side of the second welding area 424; specifically, since the side area of ​​the second welding area 424 facing away from the plug rubber core 20 is larger than the side of the second welding area 424 facing the plug rubber core 20, two power pin pads 4241 and two signal pin pads 4243 are provided on the side of the second welding area 424 facing away from the plug rubber core 20, and the signal pin pad 4243 is located between the two power pin pads 4241; the side width of the second welding area 424 facing the plug rubber core 20 is smaller, and therefore, a plurality of signal pin pads 4243 are provided on the side of the second welding area 424 facing the plug rubber core 20. In this embodiment, two signal pin pads 4243 are provided between two power pin pads 4241 on the side of the second welding area 424 facing away from the plug rubber core 20; four signal pin pads 4243 are provided on the side of the second welding area 424 facing the plug rubber core 20. Two power lines in the wire 90 are respectively welded to the two power pin pads 4241, and multiple signal lines in the wire 90 are respectively welded to multiple signal pin pads 4243. The rubber-encapsulated shell 60 wraps the circuit board 40a, the wire 90 connected to the second welding area 424, and the positioning plate 25. Since the two power pin pads 4241 are located on the outside and the signal pin pads 4243 are located on the inside, the circuit board 40 and the wire 90 are placed in the mold to fix the circuit board 40 and the wire 90, so that they cannot swing at will, and the mold can prevent the wire 90 from being crushed. If the signal line cannot be protected and fixed by the wire 90 after the position is changed, the inner mold wire and PCB board may be exposed, which is not conducive to the waterproofness of the waterproof connector plug.

[0073] Since the width of the side of the second welding area 424 close to the first welding area is larger, the pad spacing between the power pin pad 4241 and the signal pin pad 4243 can be appropriately increased, and no undesirable phenomena such as bridging will occur during wire welding. The middle part and the rear half of the first rubber coating 61 can shape and fix the wire; that is, after the welding of the wire 90 and the circuit board 40a is completed, the first rubber coating 61 is injection molded, which is beneficial to the fixed connection between the wire 90 and the circuit board 40a, and has a better waterproof effect.

[0074] In other embodiments, two signal pin pads 4243 are disposed between the two power pin pads 4241 on the side of the second welding area 424 facing away from the plug rubber core 20 ; four signal pin pads 4243 are disposed on the side of the second welding area 424 facing away from the plug rubber core 20 .

[0075] like Fig.24 As shown, the wire structure of the waterproof connector plug in the eighth embodiment of the present application is similar to the structure of the waterproof connector plug in the seventh embodiment, except that: in the eighth embodiment, the length of the first welding area 422 is less than the length of the connecting surface 251, so as to form a glue-containing area 4220 on the side of the first welding area 422 away from the second welding area 424, and the first glue-containing part is filled in the glue-containing area 4220 to make the connection between the circuit board and the plug rubber core 20 more secure and the waterproof effect better.

[0076] Please also read Figure 25-27 The wire structure of the waterproof connector plug in the ninth embodiment of the present application is similar to that of the waterproof connector plug in the first embodiment, except that: in the ninth embodiment, the first rubber-coated member 61 only wraps the connecting plate 255 of the plug rubber core 20; specifically, the first rubber-coated member 61 is provided with a rubber-receiving notch 618 connected to the waterproof groove 22, the second rubber-coated member 63 wraps the first rubber-coated member 61, and the second rubber-coated member 63 is sealed and filled in the rubber-receiving notch 618 and the waterproof groove 22, so that the plug rubber core 20 is sealed and connected with the second rubber-coated member 63. In this embodiment, the first rubber-coated member 61 wraps the plug rubber core 20, the second rubber-coated member 63 wraps the first rubber-coated member 61, and the material of the second rubber-coated member 63 fills the rubber-receiving notch 618 and the waterproof groove 22, which can further improve the waterproof effect of the waterproof connector plug. In this embodiment, a glue-receiving notch 618 connected to the waterproof groove 22 is provided in the first glue-wrapped part 61, so that the material of the second glue-wrapped part 63 fills the glue-receiving notch 618 of the first glue-wrapped part 61, thereby increasing the waterproof stroke of the waterproof connector plug and being more conducive to waterproofing of the waterproof connector plug. It can be understood that the shape of the glue-receiving notch 618 on the first glue-wrapped part 61 is not limited, that is, the cross-section of the glue-receiving notch 618 can be, but is not limited to, a rectangular surface, a circular surface, an elliptical surface, or a polygonal surface, etc. The main function of the glue-receiving notch 618 is to allow the material of the second glue-wrapped part 63 to fill the glue-receiving notch 618.

[0077] Please also read Figure 28-Figure 29The wire structure of the waterproof connector plug in the tenth embodiment of the present application is similar to that of the waterproof connector plug in the first embodiment, except that: in the tenth embodiment, the first rubber-coated part 61 of the rubber-coated shell 60 wraps the connecting plate 255, and the first rubber-coated part 61 fills the waterproof groove 22, and a rubber groove 65 is opened between the outer peripheral surface of the positioning plate 25 and the second rubber-coated part 63, and the rubber groove 65 is filled with waterproof glue 66 to achieve a multiple waterproof structure and further improve the waterproof effect of the waterproof connector plug. In this embodiment, after the waterproof glue 66 is filled in the rubber groove 65, the side of the positioning plate 25 facing the rubber core 23, the rubber-coated shell 60 and the waterproof glue 66 are coplanar. Optionally, the rubber groove 65 surrounds the edge of the positioning plate 25, and the waterproof glue 66 is sealed and connected to the positioning plate 25 and the second rubber-coated part 63. Optionally, the width of the rubber groove 65 is 0.75mm-1.0mm. In this embodiment, the rubber-coated shell 60 is made of nylon material, the plug rubber core 20 is made of LCP material, a rubber groove 65 is added to the second rubber-coated part 63, and waterproof glue is filled in the rubber groove 65, which can achieve a two-way combination of LCP material and nylon material, further improving the waterproof function of the waterproof connector plug.

[0078] Optionally, the second rubber package 63 reserves a glue groove 65 with a width of 0.75mm-1.0mm and a depth of 0.5mm-0.9mm around the positioning plate 25; currently, the epoxy resin glue on the market cannot meet the requirements of such a small glue groove, and can only be filled with silicone, because silicone can only be used as a sealant and not as a fixing glue. If the glue groove is too large, it is easy to damage the silicone, thereby causing the product to fail in waterproofing. Therefore, a glue groove with a full circle width not exceeding 0.75mm and a depth of 0.9mm is reserved on the second rubber package 63 to facilitate the later waterproofing of the waterproof connector plug.

[0079] Please also read Figure 30-Figure 31The structure of the waterproof connector plug in the eleventh embodiment of the present application is similar to that of the waterproof connector plug in the tenth embodiment, except that in the eleventh embodiment, the glue groove 65 not only surrounds the edge of the positioning plate 25, but also communicates with the waterproof groove 22, and the waterproof glue 66 is simultaneously filled in the glue groove 65 and the waterproof groove 22. Specifically, the cross section of the waterproof glue 66 is L-shaped, and the waterproof glue 66 includes a first waterproof ring 662 and a second waterproof ring 664. The first waterproof ring 662 is sealed and filled in the waterproof groove 22, and the second waterproof ring 664 is sealed and filled in the glue groove 65, thereby further improving the waterproof effect of the waterproof connector plug. The first rubber-wrapped component 61 has a groove 615 near the waterproof groove 22, and the second rubber-wrapped component 63 is filled in the waterproof groove 22; the groove 615 can increase the gluing stroke of the rubber groove 65, and also increase the contact stroke between the first rubber-wrapped component 61 and the second rubber-wrapped component 63, thereby increasing the waterproof effect of the waterproof connector plug; and the first rubber-wrapped component 61 and the second rubber-wrapped component 63 are matched near the waterproof groove 22 through the concave and convex, which can make the connection between the first rubber-wrapped component 61 and the second rubber-wrapped component 63 more stable.

[0080] Optionally, in order to better meet the waterproof performance of the waterproof connector plug and take advantage of the disadvantages of silica gel, the waterproof connector plug in this embodiment adopts the form of filling inward for gluing, and the glue groove 65 is optimized to be an L-shaped glue groove, and the glue filling stroke and glue filling amount of the glue groove 65 of the waterproof connector plug are increased on the basis of not changing the appearance of the waterproof connector plug in the tenth embodiment, so that the waterproof connector plug can achieve a better waterproof effect. The glue groove 65 in this embodiment is connected with the waterproof groove 22 to increase the glue filling stroke and glue filling amount of the waterproof connector plug, thereby increasing the waterproof effect of the waterproof connector plug; since the plug glue core 20 is made of LCP material, and the rubber-encapsulated shell 60 is made of nylon material, the LCP material is difficult to bond with other materials. If the waterproof connector plug is to be waterproof, it is necessary to use glue to achieve the bonding between the two. The longer the glue filling stroke of the glue and the LCP material, the better the waterproof effect. Therefore, the glue groove 65 in this embodiment is optimized to be an L-shaped glue filling groove, which can increase the glue filling amount of the waterproof connector plug and improve the waterproof effect.

[0081] The connector and waterproof connector plug of the embodiment of the utility model can be widely used in various types of vehicles, communications, computers and other consumer electronics, industry, transportation and other fields. For example, it can be used as a key component in new energy vehicles, electric bicycles, electric motorcycles, electric scooters, etc. Specifically, it can be used in motors of various types of vehicles, etc. Its uses are very wide and are not limited to the examples.

[0082] The embodiments of the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the embodiments above is only used to help understand the method of the present invention and its core idea.
