In a possible embodiment, the housing 125 and the sleeve body 126 are fixed by assembling, and the material of the housing 125 and the sleeve body 126 can be the same as the material of the male housing 12516 and the male sleeve 13, so as to reduce the material variety of the drive-by-wire box 10 and the cost of the drive-by-wire box 10. In another possible embodiment, the housing 125 and the sleeve body 126 are integrally formed, and the integrally formed female sleeve 121 has fewer assembly processes, which is beneficial to saving production time and cost.

The housing 125 and the sleeve body 126 may together form the mating groove 122 (the portion inside the two dotted lines in fig. 5 is the sleeve body 126, and the portion outside the two dotted lines is the housing 125). For example, the cross-sectional shape of the insertion groove 122 is approximately an inverted "T" shape, that is, the cross-sectional width of the insertion groove 122 decreases from the notch of the insertion groove 122 toward the inside of the insertion groove 122, the housing 125 forms a portion of the insertion groove 122 having a wider cross-sectional width, and the sleeve body 126 forms a portion of the insertion groove 122 having a narrower cross-sectional width. In another possible embodiment, the cross-sectional width of the insertion groove 122 may not be reduced toward the inside of the insertion groove 122, but may be maintained at the same cross-sectional width, so that the variation of the groove inner diameter of the insertion groove does not need to be controlled, the processing difficulty of the insertion groove 122 can be reduced, the consistency is good, and the cost reduction is facilitated.

As shown in fig. 5, the female housing 124 is located in the narrow cross-section portion of the insertion groove 122, and the rib 123 is located in the wide cross-section portion of the insertion groove 122. In the embodiment of the present application, since the outer shell 125 and the sleeve body 126 can jointly form the insertion groove 122, that is, a part of the inner surface of the outer shell can form a part of the inner side wall of the insertion groove 122, and the rib 123 is disposed on the inner side wall of the insertion groove 122 close to the notch, therefore, the rib 123 can be regarded as an annular protruding structure formed on the inner surface of the outer shell 125, and can be integrally formed with the outer shell 125. When the male connector 14 is plugged with the plugging groove 122, the plugging end 142 of the male connector 14 is plugged with the female seat 124 in the plugging groove 122 and is located at a part with a narrower cross section in the plugging groove 122, and the extension part 132 of the male connector sleeve 13 is located at a part with a wider cross section in the plugging groove 122 because the waterproof ring 15 on the extension part needs to abut against the convex rib 123 in the plugging groove 122 and is located at a part with a wider cross section in the plugging groove 122, so that the plugging end 142 can be plugged into the female seat 124 more reliably in a targeted manner, the extension part 132 can be fixed with the convex rib 123 more stably, the reliability is high, and the practicability is high.

Referring to fig. 4 and 5 again, the waterproof ring 15 includes an annular cylindrical surface 151, and the cylindrical surface 151 abuts against the rib 123 to form an interference fit between the waterproof ring 15 and the rib 123. It will be appreciated that the cylindrical surface 151 is the peripheral side of the waterproof ring 15, and the shape of the cylindrical surface is adapted to the shape of the extension 132, and may be a cylindrical surface or an elliptic cylindrical surface. When the male connector 14 is plugged with the plugging groove 122, a gap is formed between the cylindrical surface 151 of the waterproof ring 15 and the inner side wall of the plugging groove 122, the convex rib 123 is arranged on the inner side wall of the plugging groove 122 close to the notch, and the thickness of the convex rib 123 is larger than the width of the gap. The outer diameter of waterproof circle 15 is greater than the inner diameter of protruding muscle 123 promptly, thereby make plug end 142 receive pressure and when the pressure equipment is in inserting groove 122, the cylinder 151 of waterproof circle 15 that stretches into in inserting groove 122 produces elastic pressure because of the extrusion that receives protruding muscle 123, elastic pressure makes protruding muscle 123 tightly laminate in the cylinder 151 of waterproof circle 15, and then make seamless butt between protruding muscle 123 and the waterproof circle 15, the possibility that the sweat got into has effectively been reduced, the waterproof reliability of drive-by-wire box 10 has been improved greatly. In the embodiment of the application, the interference range of the interference fit is in the range of 0.08mm to 0.15mm, wherein the interference is the range value that the outer diameter of the waterproof ring 15 exceeds the inner diameter of the inner surface of the housing of the battery box 20, and the range value includes the end values of 0.08mm and 0.15mm, so that the interference value in the interference range can meet the interference fit between the convex rib 123 and the waterproof ring 15, the waterproof ring 15 is effectively prevented from being worn, and the wire control box 10 forms long-term reliable stable sealing performance.

In addition, set up waterproof circle 15 and have cylinder 151, and the cylinder is flat and smooth, when can making waterproof circle 15 and protruding muscle 123 contact each other, waterproof circle 15 with the surface that protruding muscle 123 contacted can be the great and smooth cylinder 151 of area of contact, the uniformity of cylinder 151 is good, high wear resistance, be difficult for producing local great wearing and tearing because of area of contact undersize, can also effectively reduce the wearing and tearing that cause in the use to protruding muscle 123, guarantee seal validity and waterproof reliability in the long-term use of drive-by-wire box 10.

It can be understood that, when the male head portion 11 is connected with the female head portion 12, the male housing 16 and the female sleeve 121 are roughly spliced to form a cylindrical box body, and the male head 14, the female seat 124 and most other components of the line control box 10 are all accommodated in the cylindrical box body, so that the overall appearance of the line control box 10 is simple and attractive, the components in the line control box can be effectively protected, and the service life of the line control box 10 is prolonged.

Referring to fig. 2, 6 and 7 together, in the embodiment of the present application, the neckline 30 includes an inner core 31 and an outer layer 32, and the inner core 31 includes a positioning portion 312 and fitting portions 311 coupled to both ends of the positioning portion 312. The positioning portion 312 and the fitting portion 311 may be integrally formed. The outer layer 32 wraps the positioning portion 312 such that the fitting portions 311 protrude from the outer layer 32, i.e., the two fitting portions 311 can be regarded as protrusions protruding from the outer layer 32 formed by extending both ends of the positioning portion 312 outward, and the two fitting portions 311 are used for connecting the male header 11 and the battery case 20, respectively. In other words, the two fitting parts 311 are the end of the napestrap wire 30 connected to the male head 11 and the end of the napestrap wire 30 connected to the battery case 20, respectively, i.e., when the napestrap wire 30 is connected between the male head 11 and the battery case 20, the two fitting parts 311 are located inside the male head 11 and the battery case 20, respectively. It can be understood that the outer layer 32 has an insulation protection function, the inner core 31 has a function of transmitting current and data, the matching part 311 of the inner core 31 can extend into the battery case 20 or the male part 11 to be connected with corresponding components to realize the functions of electrical connection and sealing, and the connection stability is strong.

The battery case 20 includes a battery case housing 21, and the shape of the battery case housing 21 may be a hollow barrel structure, so that there is enough space for the fitting portion 311 to extend into, and electronic devices such as a battery may be accommodated. The external diameter dimension of the fitting portion 311 of the neckline 30, which is connected to the battery case 20, is smaller than the internal diameter dimension of the battery case housing 21 so as to be inserted into the inside of the battery case housing 21 and electrically connected to the corresponding parts inside the battery case housing 21, thereby forming a sleeve type assembly structure. It should be noted that the sleeve type assembly structure is widely applied to the electronic device 100, and is applicable to not only the connection between the neckline 30 and the battery box housing 21, but also the connection between the first earphone line 40 and the battery box housing 21, the connection between the neckline 30 and the male housing 16, and the connection between the second earphone line 50 and the female sleeve 121 shown in fig. 2. The first earphone line 40 and the second earphone line 50 both have an inner core and an outer layer, and also have a matching part extending into the corresponding component, specifically, the matching part of the first earphone line 40 may be an end part of the first earphone line 40 departing from the first earphone 60, which can extend into the inside of the battery box case 21 to be connected with the inner surface of the battery box case 21. The fitting portion of the second earphone line 50 may be an end of the second earphone line 50 away from the second earphone 70, and may extend into the interior of the female sleeve 121 of the female head 12 to connect with the inner surface of the female sleeve 121. In the embodiment of the present application, only the connection between the neck strap 30 and the battery box casing 21 will be described, and the same technical contents in other positions will not be described again. The following detailed description will be made, and the descriptions can be applied to each connection described above, without conflict.

When the engaging portion 311 protrudes into the inside of the cartridge case 21, the engaging portion 311 located in the inside of the cartridge case 21 is spaced apart from the inner side wall of the cartridge case 21, that is, a gap is formed between the engaging portion 311 and the cartridge case 21. In one possible embodiment, the fitting part 311 further includes an adhesive layer 22, and the adhesive layer 22 is located between the fitting part 311 and the inner surface of the battery case housing 21 and adheres the fitting part 311 and the inner surface of the battery case housing 21, thereby fixing and sealing the fitting part 311 to the inside of the battery case housing 21, i.e., the adhesive layer 22 fills and seals the gap formed between the fitting part 311 and the battery case housing 21. Therefore, the matching part 311 can be conveniently and quickly fixed to the inside of the battery box shell 21 through the bonding layer 22, the sealing reliability is high, and the installation stability is high, so that the neck strap line 30 and the battery box 20 can be stably and reliably electrically connected.

It can be understood that, in the assembling process of the matching portion 311 and the battery box casing 21, when the matching portion 311 extends into the battery box casing 21, due to a possible misalignment between the matching portion 311 and the inner side wall of the battery box casing 21, the adhesive layer 22 on one side is easily scratched, so that the thicknesses of the parts of the adhesive layer 22 are inconsistent, and further the side has no adhesive force or insufficient adhesive strength, or a slight inclination may exist between the matching portion 311 and the inner side wall of the battery box casing 21, and since the adhesive layer 22 is not dried after the assembly, the two parts are relatively moved, so that the original gap is enlarged, the existing material forming the adhesive layer 22 is difficult to completely fill the gap, and complete sealing is difficult to achieve, and the possibility of sealing failure exists.

Thus, referring to fig. 6, 8 and 9, in an embodiment of the present application, the mating portion 311 includes a triangular rib 314 and an annular mating surface 313, the triangular rib 314 is disposed around the mating surface 313, and the triangular rib 314 forms an interference with the inner surface of the battery case 21. It is understood that the mating surface 313 may be an outer peripheral surface of the mating portion 311, and the cross-sectional shape of the triangular rib 314 is approximately triangular, which may be integrally formed with the mating surface 313, i.e., it may be regarded as a convex structure formed by the mating surface 313 extending outward.

When the neck strap 30 is connected to the battery case 20, a gap is formed between the engagement surface 313 of the engagement portion 311 located inside the battery case 21 and the inner side wall of the battery case 21 due to the interval arrangement, a triangular rib 314 is provided on the engagement surface 313, and the thickness of the triangular rib 314 is greater than the width of the gap. That is, the outer diameter of the triangular rib 314 (the outer diameter of the vertex of the triangular rib 314) is greater than the inner diameter of the inner surface of the battery box casing 21, so that when the fitting part 311 is assembled with the battery box casing 21, the inner surface of the battery box casing 21 is pressed by the triangular rib 314 to generate elastic pressure, the elastic pressure enables the triangular rib 314 to be tightly attached to the inner surface of the battery box casing 21, and because the triangular rib 314 is scratched to remove a part of the adaptability during the assembly process, it is ensured that no gap exists between the top of the triangular rib 314 and the inner surface of the battery box casing 21, so that the gap between the other parts of the fitting surface 313 except the position where the triangular rib 314 is arranged and the inner surface of the battery box casing 21 can be substantially uniform at the position of the fitting surface 313 after the assembly, and the circumference of the fitting part 311 can have a uniform space for accommodating the adhesive layer 22, so as to achieve complete sealing effect.

In addition, because the triangular rib 314 has a certain height, the gap can be gradually reduced and changed to 0 from the bottom of the triangular rib 314 to the top of the triangular rib, the design can ensure that for example, the positions of two bevel edges of the triangular rib 314, the adopted materials such as glue and the like for forming the adhesive layer 22 can be reduced to a certain extent, and the fixed sealing effect can be realized by relatively needing less materials, thereby saving the cost and improving the economic benefit of the product, and because the gap at the top of the triangular rib 314 is zero at the moment, and the adhesive layer 22 has the fixed effect, the waterproof reliability of the electronic device 100 can be further ensured.

In one possible embodiment, the width of the triangular rib 314 may be in a range of 0.3mm to 1.5mm, and the width of the triangular rib 314 is a length-wise dimension of the fitting portion 311. The range values include end points of 0.3mm and 1.5mm, so that the width value within the width range can seal the gap, effective sealing of the circumference of the matching part 311 can be effectively ensured, and the sleeve type assembling framework can form long-term, reliable and stable sealing performance. And the amount of interference between the triangular ribs 314 and the inner surface of the battery case housing 21 is in the range of 0.03mm to 1mm, wherein the amount of interference is in the range where the outer diameter dimension of the triangular ribs 314 exceeds the inner diameter dimension of the inner surface of the battery case housing 21, and the range includes 0.03mm and 1 mm. Because the size of the interference amount can be adjusted according to actual requirements, and the height of the triangular rib 314 can be correspondingly changed along with the change of the size of the interference amount, the size range of the triangular rib 314 can adapt to the design requirements of different scenes, and the triangular rib has strong flexibility and wide application range. For example, as shown in fig. 9, the triangular rib 314 has a width (a dimension) of 0.3mm, a height of 0.08mm, and an interference amount (B dimension) of 0.03 mm.

In a possible embodiment, if the battery case housing 21 is a metal member and the engagement portion 311 is a plastic member, the interference amount may be in the range of 0.03mm to 0.05 mm. In another possible embodiment, if the battery case housing 21 is a plastic member and the fitting portion 311 is a plastic member, the interference amount may be in the range of 0mm to 1 mm. However, in the process of assembling the engaging portion 311 and the battery case 21, the adhesive layer 22 is provided around the engaging surface 313 and then the engaging portion and the battery case are assembled, whereby both the engaging portion and the battery case can be effectively fixed and sealed, and reliability is high.

The electronic device 100 of the present application makes the male header portion 11 and the female header portion 12 connected by disposing the waterproof ring 15 on the extension portion 132 of the male header sleeve 13 of the male header portion 11 and disposing the convex rib 123 on the inner side wall of the inserting groove 122 of the female header sleeve 121 of the female header portion 12. For example, when the plugging end 142 of the male connector 14 is inserted into the plugging groove 122 of the female connector sleeve 121, the waterproof ring 15 contacts with the convex rib 123 and deforms through the pressure applied by the convex rib 123, so that the waterproof ring 15 and the convex rib 123 are fully and tightly abutted, on one hand, the plugging end 142 can be sealed in the plugging groove 122, and on the other hand, the plugging end 142 and corresponding components in the plugging groove 122 can be correspondingly plugged to realize the electrical connection between the male connector 11 and the female connector 12. On the other hand, the gap between the male connector 14 and the inserting groove 122 can be tightly and firmly sealed, which is beneficial to improving the stability and reliability of the long-term inserting and pulling use of the male connector 11 and the female connector 12, and is more beneficial to improving the waterproof performance of the electronic device 100.
