Description

Technical Field

[0001] The present application relates to the technical field of the assembly of conductive connecting wires, and particularly to an assembly structure of a wire harness and an electronic device. Background Art

[0002] At the connection between the outer sleeve of a conductive connecting wire such as a power cord and a data wire and the housing, a strain relief (SR) joint is usually provided. The strain relief joint is used to eliminate the stress of the wire, and can prevent the core wire in the wire from being broken when the wire is pulled. In the related art, when installing a conductive connecting wire on the housing of an electronic device, the strain relief joint is usually arranged between the upper and lower housings of the housing. Semi-circular holes are provided at the edges of the upper and lower housings. When the upper and lower housings are spliced, the two semi-circular holes are spliced to form an opening for the strain relief joint to pass through, and the strain relief joint is fixed by the pressing of the upper and lower housings.

[0003] However, when splicing the upper and lower housings, due to reasons such as processing errors or inaccurate installation alignment, the alignment of the semi-circular holes of the upper and lower housings is not accurate enough to cause misalignment, and further damage to the strain relief joint when the upper and lower housings press the strain relief joint. Summary of the Utility Model

[0004] The present application provides an assembly structure of a wire harness and an electronic device, which does not need to fix the strain relief joint by pressing the first housing and the second housing, and the installation hole can be set at any position on the protective housing except the splicing gap, so as to avoid damaging the strain relief joint when the upper and lower housings are pressed.

[0005] In a first aspect, the present application provides an assembly structure of a wire harness, including: a protective housing having a protective cavity, an installation hole communicated with the protective cavity is provided on the protective housing, and the installation hole is used for the strain relief joint of the conductive connecting wire to pass through; and a limiting member located in the protective cavity and connected to the protective housing, the limiting member is used to limit and fix the strain relief joint to the protective housing; wherein, the protective housing includes a first housing and a second housing disposed opposite to the first housing, the first housing and the second housing are connected to enclose the protective cavity, a splicing gap is provided at the connection between the first housing and the second housing, the installation hole is provided on the first housing or / and the second housing, and the installation hole is spaced from the splicing gap.

[0006] In some embodiments of the present application, the limiting member includes: a limiting portion having a limiting groove for inserting the wire buckle joint, the limiting groove extending in a first direction through the limiting portion, and a bayonet is provided on one side of the limiting portion along a second direction, the bayonet communicating with the limiting groove for allowing the wire buckle joint to enter and exit the limiting groove, the first direction being parallel to the thickness direction of the limiting portion, and the second direction being perpendicular to the first direction; a connecting portion connecting the limiting portion and the protective shell. When installing the wire buckle joint, the wire buckle joint can be first inserted into the installation hole from the outside of the shell, and then after adjusting the position of the limiting member, the limiting member is moved along the second direction so that the wire buckle joint is inserted into the limiting groove through the bayonet, and the connecting portion is connected to the shell, so that the wire buckle joint can be limited and fixed to the protective shell, making the fixing of the wire buckle joint more convenient.

[0007] In some embodiments of the present application, a groove is provided on the outer peripheral side surface of the wire buckle joint. When the wire buckle joint is inserted into the limiting groove, a part of the limiting portion forming the limiting groove is inserted into the groove and is engaged with the groove. This makes the fixing of the wire buckle joint more firm.

[0008] In some embodiments of the present application, an installation structure is provided on the inner side wall of the protective cavity, and the connecting portion is detachably connected to the installation structure. This facilitates the maintenance and replacement of the conductive connecting wire of the wire buckle joint.

[0009] In some embodiments of the present application, the connecting portion is engaged with the installation structure or connected by a connecting member. The connection between the connecting portion and the installation structure is relatively convenient and simple, making the loading and unloading of the limiting member more convenient.

[0010] In some embodiments of the present application, the installation structure includes installation bumps provided on opposite sides of the limiting portion, and a first slot extending in the second direction is formed between two oppositely arranged installation bumps, and the limiting portion is inserted into the first slot along the second direction. This makes the fixing of the wire buckle joint more firm.

[0011] In some embodiments of the present application, the connecting portion is located on the side of the installation bump away from the limiting portion, and a buckle is provided on the connecting portion, and a card slot is provided on the side of the installation bump away from the limiting portion, and the buckle is engaged with the card slot to be engaged with the installation structure. This realizes the engagement between the connecting portion and the installation structure, and further realizes the detachable connection between the connecting portion and the installation structure.

[0012] In some embodiments of the present application, a second slot extending in the second direction is formed between the connecting portion and the limiting portion, and the end of the installation bump is inserted into the second slot. This makes the fixing of the wire buckle joint more firm.

[0013] In some embodiments of the present application, the mounting structure and the bayonet are located on the same side of the limiting member, the connecting portion is opposite to the mounting structure in position, and is detachably connected to the mounting structure through a connecting member. The mounting structure can provide limit and in-place reminder for the limiting member, making the installation of the mounting member more convenient.

[0014] In some embodiments of the present application, a limiting structure is provided on the inner side wall of the protection cavity. The limiting structure and the bayonet are located on the same side of the limiting portion. When the wire buckle joint is inserted into the limiting groove, the wire buckle joint contacts the limiting structure. Through the cooperation of the limiting portion and the limiting structure, the circumferential side of the wire buckle joint can be limited, preventing the wire buckle joint from disengaging from the limiting groove of the bayonet.

[0015] In some embodiments of the present application, a counterbore is provided on the outer side surface of the protection shell. The counterbore is arranged along the circumference of the mounting hole and is communicated with the mounting hole. When the wire buckle joint is inserted into the mounting hole, it contacts the wall surface of the counterbore. This can prevent dust and other dirt from entering the gap between the thick wire segment and the shell during the process of pulling the conductive connecting wire.

[0016] In some embodiments of the present application, the first shell includes a first side plate, a second side plate and a third side plate connected to the first side plate, and the second shell includes a fourth side plate, a first end plate and a second end plate connected to the fourth side plate. Among them, the first side plate and the fourth side plate are arranged opposite to each other, the second side plate and the third side plate are arranged opposite to each other and are located between the first side plate and the fourth side plate, the first end plate and the second end plate are arranged opposite to each other and are located between the first side plate, the second side plate, the third side plate and the fourth side plate. This enables more position choices for the mounting hole and can keep a greater distance from the splicing gap, thereby enabling the wire buckle joint to maintain a greater creepage distance and electrical clearance from the electronic component, so as to further enhance the safety performance of the electronic device.

[0017] In some embodiments of the present application, the protection shell and the limiting member are hard rubber parts made of hard rubber material. This enables the protection shell and the limiting member to have sufficient structural strength and stability, and can also prevent the protection shell and the limiting member from causing excessive wear to the wire buckle joint when contacting it.

[0018] In a second aspect, the present application further provides an electronic device, including a conductive connecting wire, a control component, and an assembly structure as described in any one of the above embodiments. The control component is arranged in the protection cavity, the conductive connecting wire includes the wire buckle joint, and the wire buckle joint passes through the mounting hole and is electrically connected to the control component.

[0019] In some embodiments of the present application, the electronic device is a hair removal device, which can improve the aesthetic appearance and safety performance of the hair removal device.

[0020] The beneficial effects of the present application are as follows: By providing a limiting member to fix the wire buckle joint, there is no need to set the installation hole at the splicing gap, and there is no need to use the pressing of the first housing and the second housing to fix the wire buckle joint. The installation hole can be set at any position on the protective housing except the splicing gap, so as to avoid damaging the wire buckle joint when the upper and lower housings are pressed together. In addition, the installation hole can be set according to the installation position of electronic components such as the circuit board in the protection cavity, so that the wire buckle joint can avoid the electronic components, and further keep a sufficient creepage distance and electrical clearance between the wire buckle joint and the electronic components, reduce the safety hazard between the wire buckle joint and the electronic components, and enhance the safety performance of the electronic device. In addition, in the present application, by using a limiting member to fix the wire buckle joint, the shape and size of the installation hole can be designed to be adapted to the wire buckle joint, and the wire buckle joint can pass through the installation hole more smoothly, so as to prevent the wire buckle joint from being damaged during the installation process, and the installation is more convenient, and the wire buckle joint can be fixed more firmly.

[0035] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] In the related art, when installing a conductive connecting wire on the housing of an electronic device, usually the wire buckle joint is arranged between the upper and lower housings of the housing. Semi-circular holes are provided at the edges of the upper and lower housings. When the upper and lower housings are spliced, the two semi-circular holes are spliced to form an opening for the wire buckle joint to pass through, and the wire buckle joint is fixed by pressing the upper and lower housings together.

[0037] However, when splicing the upper and lower shells, due to reasons such as machining errors or inaccurate installation alignment, the semi-circular holes of the upper and lower shells may not be accurately aligned, resulting in misalignment, and further causing damage to the wire buckle joint when the upper and lower shells are pressed together. In addition, electronic components such as circuit boards inside the housing of the electronic device are usually close to the joint seam of the upper and lower shells, resulting in a small creepage distance and electrical clearance between the wire buckle joint and the electronic components such as the circuit board, posing a greater potential safety hazard.

[0038] Based on the above technical problems, the present application provides an assembly structure of a wire harness and an electronic device to solve the above technical problems.

[0039] In the first aspect, the present application provides an assembly structure of a wire harness, as Figure 1 and Figure 2 shown, the assembly structure includes a protective shell 10 and a limiting member 20.

[0040] Among them, the protective shell 10 includes a protective cavity 13, and the protective shell 10 is provided with a mounting hole 14 communicating with the protective cavity 13 (as Figure 5 ), the mounting hole 14 is used for the wire buckle joint 61 of the conductive connection wire 60 to pass through; the protective shell 10 can be a cube, a long strip, a cylinder or other shapes, and the present application does not make specific limitations. The conductive connection wire 60 can be a power cord, a data line or other types of conductive wires, and the wire buckle (strain relief, SR) joint 61 is a joint provided at the connection between the outer sleeve of the wire body of the conductive connection wire 60 and the housing. The wire buckle joint 61 is used to eliminate the stress of the wire, and can prevent the core wire in the wire from being broken when the wire is pulled. The whole of the wire buckle joint 61 can be a cube, a cylinder or other shapes.

[0041] The limiting member 20 is located in the protective cavity 13 and is connected to the protective shell 10. The limiting member 20 is used to limit and fix the wire buckle joint 61 to the protective shell 10. The protective shell 10 includes a first shell 11 and a second shell 12 disposed opposite to the first shell 11. The first shell 11 and the second shell 12 are connected to enclose the protective cavity 13. The connection between the first shell 11 and the second shell 12 has a splicing gap 15. The mounting hole 14 is provided on the first shell 11 or / and the second shell 12, and the mounting hole 14 is spaced apart from the splicing gap 15.

[0042] It can be understood that in the present application, by setting the limiting member 20 to fix the wire buckle joint 61, there is no need to set the mounting hole 14 at the splicing gap 15, and there is no need to use the pressing of the first shell 11 and the second shell 12 to fix the wire buckle joint 61. The mounting hole 14 can be set at any position on the protective shell 10 except the splicing gap 15, so as to avoid damaging the wire buckle joint 61 when the upper and lower shells are pressed together.

[0043] In addition, the installation holes 14 can be set according to the installation positions of electronic components such as the circuit board in the protection cavity 13, so that the wire buckle connector 61 can avoid the electronic components, and further, the wire buckle connector 61 can maintain a sufficient creepage distance (the shortest distance along the surface of the insulating material between two conductor components) and electrical clearance (the shortest path in the air between two conductor components) from the electronic components, reducing the potential safety hazards between the wire buckle connector 61 and the electronic components and enhancing the safety performance of the electronic device.

[0044] It should also be noted that, compared with squeezing the wire buckle connector 61 into the installation hole 14 and using the friction between the outer soft rubber layer of the wire buckle connector 61 and the hole wall of the installation hole 14 to fix the wire buckle connector 61, it is easy to cause damage to the wire buckle connector 61, and the installation and fixation are relatively difficult and not firm enough. In the present application, the wire buckle connector 61 can be fixed by the limiting member 20, so that the shape and size of the installation hole 14 can be designed to be adapted to the wire buckle connector 61, and the wire buckle connector 61 can pass through the installation hole 14 more smoothly, thereby preventing damage to the wire buckle connector 61 during the installation process, and the installation is more convenient, and the wire buckle connector 61 can be fixed more firmly.

[0045] Among them, the shape of the installation hole 14 can be circular, rectangular, triangular, pentagonal or other shapes, which is not specifically limited in the present application. The shape of the installation hole 14 is preferably adapted to the shape of the maximum longitudinal section of the wire buckle connector 61; the installation hole 14 can be provided only on the first housing 11 or the second housing 12, or can be provided on both the first housing 11 and the second housing 12 at the same time, and the number of the installation holes 14 can be 1, 2 or more.

[0046] Continue to refer to Figure 1 and Figure 2 As shown, in some embodiments of the present application, the first housing 11 includes a first side plate 111, a second side plate 112 and a third side plate 113 connected to the first side plate 111, and the second housing 12 includes a fourth side plate 121, a first end plate 122 and a second end plate 123 connected to the fourth side plate 121.

[0047] Among them, the first side plate 111 is disposed opposite to the fourth side plate 121, the second side plate 112 is disposed opposite to the third side plate 113 and is located between the first side plate 111 and the fourth side plate 121, the first end plate 122 is disposed opposite to the second end plate 123 and is located between the first side plate 111, the second side plate 112, the third side plate 113 and the fourth side plate 121. It can be understood that when the first housing 11 and the second housing 12 are spliced, the second side plate 112 and the third side plate 113 are connected to the fourth side plate 121, the first end plate 122 and the second end plate 123, and the first end portion and the second end plate 123 are connected to the first side plate 111. There are splicing gaps 15 between the respective plates of the first housing 11 (the first side plate 111, the second side plate 112, the third side plate 113) and the respective plates of the second housing 12 (the fourth side plate 121, the first end plate 122, the second end plate 123), and the splicing gaps 15 are all located at the edges of the protective housing 10. The mounting holes 14 can have more position options and can maintain a greater distance from the splicing gaps 15. Furthermore, the creepage distance and the electrical clearance between the wire buckle joint 61 and the electronic components are made larger, so as to further enhance the safety performance of the electronic device.

[0048] It should also be noted that, as Figure 1 shown, the mounting holes 14 can be provided on the side plates of the protective housing 10 (the first side plate 111, the second side plate 112, the third side plate 113, the fourth side plate 121), as Figure 8 shown, the mounting holes 14 can also be provided on the end plates of the protective housing 10 (the first end plate 122, the second end plate 123).

[0049] As Figures 3 to 6 shown, in some embodiments of the present application, the limiting member 20 includes a limiting portion 21 and a connecting portion 22.

[0050] Among them, the limiting portion 21 has a limiting groove 211 for the wire buckle joint 61 to be inserted. The limiting groove 211 extends along the first direction XX to penetrate the limiting portion 21. A bayonet 212 is provided on one side of the limiting portion 21 along the second direction YY. The bayonet 212 communicates with the limiting groove 211 and is used for the wire buckle joint 61 to enter and exit the limiting groove 211. The first direction XX is parallel to the thickness direction of the limiting portion 21, and the second direction YY is perpendicular to the first direction XX; the connecting portion 22 connects the limiting portion 21 to the protective housing 10. It can be understood that the limiting portion 21 is used to limit and fix the wire buckle joint 61. Refer to Figure 4As shown in the figure, when installing the wire buckle joint 61, the wire buckle joint 61 can be first inserted into the installation hole 14 from the outside of the protective shell 10. A part of the wire buckle joint 61 is inserted into the protective cavity 13 through the installation hole 14. Then, the bayonet 212 of the limiting part 21 is directed towards the part of the wire buckle joint 61 inserted into the protective cavity 13. After adjusting the position of the limiting member 20, the limiting member 20 is moved along the second direction YY, so that the wire buckle joint 61 is inserted into the limiting groove 211 through the bayonet 212, and the connecting part 22 is connected to the protective shell 10, and the wire buckle joint 61 can be limited and fixed to the protective shell 10.

[0051] In an embodiment, a groove 611 is provided on the outer peripheral side surface of the wire buckle joint 61. When the wire buckle joint 61 is inserted into the limiting groove 211, the part of the limiting part 21 that forms the limiting groove 211 is inserted into the groove 611 and is clamped with the groove 611. It can be understood that, taking Figure 4 a perspective as an example, during the process of the wire buckle joint 61 being inserted into the limiting groove 211 through the bayonet 212, the groove wall of the limiting groove 211 will also be inserted into the groove 611. Through the cooperation between the limiting part 21 and the groove 611, the front-back direction of the wire buckle joint 61 can be limited, preventing the wire buckle joint 61 from being pulled out of the installation hole 14 during use, and at the same time, the connection between the limiting member 20 and the wire buckle joint 61 can be made more tight, so that the wire buckle joint 61 is fixed more firmly.

[0052] In some embodiments of the present application, an installation structure 30 is provided on the inner side wall of the protective cavity 13. The connecting part 22 is detachably connected to the installation structure 30, so that the limiting member 20 can be disassembled, which is convenient for overhauling and replacing the conductive connecting wire 60 of the wire buckle joint 61. And compared with connecting the connecting part 22 to the inner wall surface of the protective shell 10, connecting the connecting part 22 to the protective shell 10 through the connection with the installation structure 30 makes the connection between the connecting part 22 and the protective shell 10 more convenient.

[0053] Among them, the connecting part 22 is clamped with the installation structure 30 (such as Figure 3 ) or connected through a connecting piece 40 (such as Figure 7 ) to achieve detachable connection with the installation structure 30, and the connection between the connecting part 22 and the installation structure 30 is relatively convenient and simple, making the loading and unloading of the limiting member 20 more convenient.

[0054] Such as Figures 3 to 5As shown, in one embodiment, the mounting structure 30 includes mounting bumps 31 provided on opposite sides of the limiting portion 21. A first slot 32 extending along the second direction YY is formed between the two oppositely arranged mounting bumps 31, and the limiting portion 21 is inserted into the first slot 32 along the second direction YY. It can be understood that, on the basis of being connected to the connecting portion 22, the mounting structure 30 can also provide limitation for the limiting portion 21, thereby improving the connection strength between the limiting member 20 and the mounting structure 30, further making the wire buckle joint 61 more firmly fixed. Moreover, the first slot 32 can also provide positioning for the limiting portion 21, making the installation of the limiting member 20 more convenient.

[0055] Among them, the connecting portion 22 is located on the side of the mounting bump 31 away from the limiting portion 21, and a buckle 23 is provided on the connecting portion 22. A slot 311 is provided on the side of the mounting bump 31 away from the limiting portion 21. The buckle 23 is engaged with the slot 311 to achieve the snap connection between the connecting portion 22 and the mounting structure 30, and further achieve the detachable connection between the connecting portion 22 and the mounting structure 30.

[0056] Further, a second slot 24 extending along the second direction YY is formed between the connecting portion 22 and the limiting portion 21. The end of the mounting bump 31 is inserted into the second slot 24, which can further improve the connection strength between the limiting member 20 and the mounting structure 30, and further make the wire buckle joint 61 more firmly fixed. When installing the wire buckle joint 61, during the process of moving the limiting member 20 along the second direction YY so that the wire buckle joint 61 is inserted into the limiting slot 211 through the bayonet 212, the limiting portion 21 is inserted into the first slot 32, and the end of the mounting bump 31 is inserted into the second slot 24. When moving to the point where the buckle 23 is engaged with the slot 311, the limiting member 20 is fixed on the protective shell 10, thereby fixing the wire buckle joint 61 on the protective shell 10.

[0057] As Figures 7 to 9 shown, in some other embodiments of the present application, the mounting structure 30 and the bayonet 212 are located on the same side of the limiting member 20. The connecting portion 22 is opposite to the mounting structure 30 in position and is detachably connected to the mounting structure 30 through a connecting member 40. It can be understood that, taking Figure 7 the shown perspective as an example, both the bayonet 212 and the mounting structure 30 are located below the limiting member 20. When installing the limiting member 20, the limiting member 20 moves downward along the second direction YY above the limiting structure 50. When the connecting portion 22 abuts against the mounting structure 30, it indicates that the limiting member 20 has reached the installation position. The mounting structure 30 can provide limitation and in-place reminder for the limiting member 20, making the installation of the mounting member more convenient. Among them, the connecting member 40 can be a screw, which can sequentially pass through the connecting portion 22 and the mounting structure 30 from top to bottom through threads and be threadedly connected to the connecting portion 22 and the mounting structure 30, thereby achieving the detachable connection between the limiting member 20 and the mounting structure 30.

[0058] As Figure 3 and Figure 7 shown, in some embodiments of the present application, a limiting structure 50 is provided on the inner side wall of the protection cavity 13. The limiting structure 50 and the bayonet 212 are located on the same side of the limiting portion 21. When the wire buckle joint 61 is inserted into the limiting groove 211, the wire buckle joint 61 contacts the limiting structure 50. It can be understood that, taking Figure 3 a perspective as an example, the limiting portion 21 can stably limit the left and right sides and the upper side of the wire buckle joint 61, and the limiting structure 50 can limit the lower side of the wire buckle joint 61. Through the cooperation of the limiting portion 21 and the limiting structure 50, the circumferential side of the wire buckle joint 61 can be limited to prevent the wire buckle joint 61 from disengaging from the limiting groove 211 of the bayonet 212.

[0059] Among them, the limiting structure 50 and the mounting structure 30 can be arranged at intervals (such as Figure 3 ), and the limiting structure 50 and the mounting structure 30 can also be integrally formed (such as Figure 7 ).

[0060] As Figure 10 and Figure 11 shown, in some embodiments of the present application, a counterbore 16 is provided on the outer side surface of the protection shell 10. The counterbore 16 is arranged along the circumferential side of the mounting hole 14 and is communicated with the mounting hole 14. When the wire buckle joint 61 is inserted into the mounting hole 14, it contacts the wall surface of the counterbore 16.

[0061] It should be noted that the wire buckle joint 61 usually includes several line segments with different diameters. A stepped structure will be formed at the connection between the thick line segment and the thin line segment. The thin line segment is used to insert into the mounting hole 14, and the thick line segment is located outside the protection shell 10 and contacts the protection shell 10 to limit the conductive connection wire 60. Compared with the thick line segment contacting the outer side surface of the protection shell 10, since the conductive connection wire 60 has a certain stretchability, when the user pulls the conductive connection wire 60 outwards, the gap between the thick line segment and the protection shell 10 will become larger, and dirt such as dust is likely to enter the gap between the thick line segment and the protection shell 10.

[0062] In the present application, by providing the counterbore 16 on the outer side surface of the protection shell 10, part of the thick line segment is hidden in the counterbore 16. When the conductive connection wire 60 is pulled outwards, the end surface where the thick line segment contacts the wall surface of the counterbore 16 is still located in the counterbore 16, which can prevent dirt such as dust from entering the gap between the thick line segment and the protection shell 10 during the process of pulling the conductive connection wire 60.

[0063] In one embodiment, the protective shell 10 and the limiting member 20 are hard rubber parts made of a hard rubber material. The protective shell 10 and the limiting member 20 can be formed of ABS (Acrylonitrile Butadiene Styrene) plastic, PC (polycarbonate) plastic, a mixture of ABS and PC, or other materials, so that the protective shell 10 and the limiting member 20 can not only have sufficient structural strength and stability, but also prevent the protective shell 10 and the limiting member 20 from causing significant wear to the wire buckle joint 61 when contacting the wire buckle joint 61.

[0064] In a second aspect, based on the above assembly structure, the present application further provides an electronic device. The electronic device includes a conductive connecting wire 60, a control component, and the assembly structure according to any one of the above embodiments.
