Description

Technical Field

[0001] This utility model relates to the field of wire connection technology, and in particular to a rotatable wire connection assembly and a handheld device having the assembly. Background Technology

[0002] Power cords are widely used in various electrical appliances, especially in the power supply connections of many household appliances, particularly handheld ones, where the application requirements are quite complex. For example, household appliances used for hair care are equipped with power cords to provide power. During use, the movement of the appliance or hair care tool within the space causes the power cord, which is connected to the tail of the appliance's casing, to bend and become tangled with the body. When one end of the power cord is bent, it can easily cause excessive load at the junction, posing a risk of explosion and a safety hazard. At the same time, the power cord, fixed to the tail of the casing, also restricts the flexible use of handheld household appliances.

[0003] Therefore, it is necessary to provide an improved wire connection structure to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a wire connection component and a handheld device having the component, so that it can rotate and swing within a certain angle, thereby facilitating flexible use by people.

[0005] One embodiment of this utility model provides a wire connection assembly, which includes a housing and a wire assembly. The housing has a receiving cavity with an inner wall surface that is spherically shaped, a first opening and a second opening communicating with the receiving cavity and the outer side of the housing, and the first opening and the second opening are arranged opposite to each other. The wire assembly has a connecting component that is oscillatingly disposed in the receiving cavity, a first lead portion and a second lead portion that extend from both ends of the connecting component to the first opening and the second opening, respectively. The connecting component includes a first connector connected to the first lead portion and a second connector connected to the second lead portion. The first connector and the second connector are connected to each other along the axial direction of the first connector and are rotatably engaged with the axis of the first connector as the center.

[0006] Furthermore, a limiting structure is provided between the first connector and the housing to restrict the first connector from rotating about its axis.

[0007] Furthermore, the limiting structure has a protrusion and a groove disposed between the first connector and the housing, the groove extending along the meridian direction of the outer wall surface of the connector assembly or the inner wall surface of the housing, and the extension length being greater than the length of the protrusion.

[0008] Furthermore, the extension length of the groove is less than the length of the outer wall surface of the connecting component in the meridian direction, so as to limit the swing angle of the connecting component within a certain angle, wherein the certain angle is less than the angle between the axis of the connecting component and the line connecting the center of the connecting component to the inner edge of the second opening.

[0009] Furthermore, the connecting component has a central section perpendicular to the axis of the first connector, and the aforementioned certain angle is not greater than the angle between the line connecting the center of the connecting component to the inner edge of the first opening and the central section.

[0010] Furthermore, the housing has a first housing and a second housing that are mated together along the opening direction of the first opening. The first housing is located around the first connector, and the second housing is located around the second connector. The inner diameter of the accommodating cavity portion inside the first housing is larger than the inner diameter of the accommodating cavity portion inside the second housing. The outer wall surface of the first connector and the outer wall surface of the second connector are located on the same spherical surface.

[0011] Furthermore, the housing has a first housing and a second housing that are mated together along the opening direction of the first opening. The first housing is located around the first connector, and the second housing is located around the second connector. The mating parts of the first housing and the second housing are nested. On the outside of the accommodating cavity, the first housing and the second housing abut against each other along the aforementioned opening direction. On the inside of the accommodating cavity, the inner wall surfaces of the first housing and the inner wall surfaces of the second housing are spaced apart along the meridian direction.

[0012] Furthermore, the first connector has a first body portion and a first insertion portion extending from the axis of the first body portion toward the second connector, the second connector has a second body portion and a second insertion portion extending from the axis of the second body portion toward the first connector, and the first insertion portion and the second insertion portion have conductors that are connected to each other along the axis of the connecting assembly.

[0013] Furthermore, the first plug-in portion has a columnar first support portion, a first conductor disposed at the center of the first support portion and protruding toward the second connector, and a second conductor disposed around the periphery of the first support portion; the second plug-in portion has a second support portion and a third conductor protruding from the second support portion toward the first plug-in portion; the second support portion is provided with a plug groove for inserting the first conductor and a fourth conductor disposed in the plug groove; the third conductor is formed into a snap ring shape to snap-fit ​​with the second conductor.

[0014] Furthermore, the first body portion has a recessed portion in the middle of the side opposite to the second connector, and the first lead portion extends from the middle of the recessed portion in the direction opposite to the second connector, and there is a certain gap between the inner wall surface of the recessed portion and the first lead portion.

[0015] Furthermore, a damping adjustment structure is provided between the second connector and the housing.

[0016] This utility model also provides a handheld device, which includes a base and the aforementioned wire connection assembly. The wire connection assembly is fixed inside the base by a housing. The base has a lead wire opening, and a second opening communicates with the lead wire opening. At least a portion of the second connector protrudes from the lead wire opening from the base.

[0017] Furthermore, the base has a housing with a receiving cavity, and a fastener disposed within the housing and fixed to the housing; the housing has an end wall located on a first end face adjacent to a second opening of the housing, and a side wall connected to the end wall and limited to the circumferential periphery of the housing; the fastener has a first limiting portion located on the side of the first housing away from the second housing.

[0018] Furthermore, the housing has a first housing and a second housing that are connected to each other along the opening direction of the first opening. A stepped surface is formed between the second end face of the second housing near the first opening and the outer wall of the first housing. The fixing member is also provided with a second limiting part protruding toward the second housing, and the second limiting part abuts against the stepped surface.

[0019] This invention features a swivelly mounted wire assembly within the housing, allowing the lead wire to be connected to cables at varying angles to accommodate different usage needs, thus preventing the risk of cable bending and damage. Furthermore, by enabling the second connector to rotate relative to the first connector, the second lead wire can rotate under circumferential rotational force, effectively preventing the cable connected to the second lead wire from twisting or tangling. This facilitates flexible use and improves the user experience. Attached Figure Description

[0029] The following detailed description incorporates the accompanying drawings, which form part of this specification. The illustrative embodiments mentioned in the specification and drawings are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art will understand, based on the teachings of this application, that many other embodiments can be employed and various changes can be made to the described embodiments without departing from the spirit and scope of this utility model. It should be understood that the various aspects of this application illustrated herein can be arranged, substituted, combined, separated, and designed in many different configurations, all of which are within the scope of this application.

[0030] Please see Figures 1 to 9 As shown, this utility model provides a wire connection assembly 100, which can be applied to a handheld device 600. The wire connection assembly 100 is fixedly installed in the base of the handheld device 600 or on the cable to adapt to the usage requirements such as the extension angle or rotation of the cable during operation of the handheld device 600. Therefore, this utility model also relates to a handheld device 600 having the aforementioned wire connection assembly 100.

[0031] Please see Figures 1 to 5 As shown, the wire connection assembly 100 includes a housing 1 and a wire assembly 2 that is configured to cooperate with the housing 1.

[0032] The housing 1 has a accommodating cavity 10 with an inner wall surface that is spherical, and a first opening 110 and a second opening 120 that connect the accommodating cavity 10 and the outer side of the housing 1. The first opening 110 and the second opening 120 are arranged opposite to each other.

[0033] The wire assembly 2 has a connecting component 21 that can be oscillatingly disposed in the accommodating cavity 10, a first lead portion 26 and a second lead portion 27 extending from both ends of the connecting component 21 with a first opening 110 and a second opening 120 respectively; wherein, the connecting component 21 includes a first connector 22 connected to the first lead portion 26 and a second connector 23 connected to the second lead portion 27, the first connector 22 and the second connector 23 are connected to each other along the axial direction of the first connector 22, and can rotate around the axis of the first connector 22.

[0034] Through the above-described configuration, on the one hand, the wire assembly 2 can swing within the housing 1, thereby allowing its lead portion to change angle according to usage requirements when connecting cables, avoiding the risk of cable bending and causing damage. On the other hand, by allowing the second connector 23 connecting the second lead portion 27 to rotate relative to the first connector 22, the second lead portion 27 can rotate with the force when subjected to circumferential rotational tension, effectively preventing the cable connected to the second lead portion 27 from twisting or tangling, thus facilitating flexible use and improving the user experience. In this embodiment, the first lead portion 26 is used to fix and connect the lead inside the handheld device 600, and the second lead portion 27 is used to connect the external cable.

[0035] Specifically, such as Figures 1 to 5 As shown, in one embodiment of this utility model, the overall shape of the housing 1 is cylindrical to facilitate installation in various application scenarios. To facilitate the installation of the connecting component 21, the housing 1 is configured with a first housing 11 and a second housing 12 that are interlocked, and the accommodating cavity 10 is formed between the first housing 11 and the second housing 12. In this embodiment, the first housing 11 and the second housing 12 are abutted against each other along the opening direction of the first opening 110. The first housing 11 is located around the first connecting member 22, and the second housing 12 is located around the second connecting member 23. Therefore, the inner wall surface of the second housing 12, which accommodates the second connecting member 23, is continuous in the circumferential direction around the central axis of the housing 1, thus allowing for smoother rotation of the second connecting member 23 relative to the first connecting member 11.

[0036] When the first housing 11 and the second housing 12 are joined together along the aforementioned opening direction, the joining portions are nested. Specifically, the first housing 11 has a first housing body 111 and a first extension 112 extending from the first housing body 111 toward the second housing 12. The outer diameter of the first extension 112 is smaller than the outer diameter of the first housing body 111, so as to form an abutment surface on the outer side of the first housing body 111 adjacent to the first extension 112.

[0037] Accordingly, the second housing 12 has a second housing body 121 and a second extension 122 extending from the second housing body 121 toward the first housing 11. The outer diameter of the second extension 122 is the same as the outer diameter of the second housing body 121, but the inner wall surface of the second extension 122 is recessed relative to the inner wall surface of the second housing body 121 to form a stepped portion on the inner side of the second housing body 121 adjacent to the second extension 122.

[0038] When the first housing 11 and the second housing 12 are inserted into each other, the first extension 112 is nested inside the second extension 122, and the abutting surface of the first housing body 111 abuts against the end face of the second extension 122. As one embodiment of the present invention, the first extension 112 can be configured as an elastic wall with a certain deformation capacity, and its maximum outer diameter before installation is greater than the inner diameter of the second extension 122, so that after installation, the first extension 112 is tightly fitted and fixed inside the second extension 122.

[0039] Furthermore, in this embodiment, the extension length of the first extension 112 is set to be less than the extension length of the second extension 122, so that on the outside of the accommodating cavity 10, the first housing 11 and the second housing 12 abut against each other along the aforementioned opening direction to restrict their axial installation positions; while on the inside of the accommodating cavity 10, the inner wall surface of the first housing 11 and the inner wall surface of the second housing 12 are spaced apart along the meridian direction, that is, in the meridian direction, the inner wall surfaces of the first housing 11 and the second housing 12 are not continuous, so as to avoid the formation of obvious edges on the inner wall surfaces of the upper and lower housings, which would affect the smoothness of the swing of the wire assembly 2 in the accommodating cavity 10.

[0040] In a preferred embodiment of this utility model, the inner diameter of the accommodating cavity 10 on the inner side of the first housing 11 is set to be larger than the inner diameter of the accommodating cavity 10 on the inner side of the second housing 12. The outer wall surface of the first connector 22 and the outer wall surface of the second connector 23 are located on the same spherical surface. That is to say, the connecting component 21 is approximately spherical, which can be a complete sphere or a part of a sphere. In this embodiment, the connecting component 21 is a part of a sphere. With this setting, the smooth swing of the connecting component 21 will not be affected regardless of whether the inner wall surfaces of the first housing 11 and the second housing 12 are continuous after they are docked.

[0041] In addition, to facilitate the installation and positioning of the wire connection assembly 100 onto the handheld device 600, in this embodiment, a stepped surface 126 is formed between the second end face of the second housing 12 near the first opening 110 and the outer wall of the first housing 11. The stepped surface 126 refers to the fact that the outer diameter of the second housing 12 is larger than the outer diameter of the first housing 11, so that after the two housings are partially joined, the second housing 12 protrudes radially outward beyond the outer wall of the first housing 11, thereby forming a stepped surface 126 that can be used for the outer structure to abut and limit the positioning.

[0042] Furthermore, a boss 113 is provided on the outer wall surface of the first housing 11. The boss 113 is spaced apart from the stepped surface 126 of the second housing 12, thereby forming a slot 13 between the boss 113 and the stepped surface 126 of the second housing 12. The wire connection assembly 100 can also be fixedly installed by the cooperation of the slot 13 with the external structure.

[0043] Furthermore, in this embodiment, the axial length of the first housing 11 is less than the axial length of the second housing 12, the center of the accommodating cavity 10 is located within the second housing 12, and the mating portion of the first connector 22 and the second connector 23 is located within the second housing 12. Therefore, when the first housing 11 is placed inside the base of the handheld device 600, the volume occupied in the base can be reduced. The center of the accommodating cavity 10 refers to the center of the sphere of the accommodating cavity 10. Additionally, the inner diameter of the first opening 110 is larger than the inner diameter of the second opening 120. This allows the first opening 110 to adapt to the complex environment inside the base, improving its containment capacity. Furthermore, the second opening 120 limits the swing angle of the second lead portion 27, ensuring good usability.

[0044] Please see Figure 2 , Figure 4 and Figure 5 As shown, a limiting structure is provided between the first connector 22 and the housing 1 to restrict the first connector 22 from rotating around its axis. By limiting the first connector 22, it can only swing around its axis and cannot rotate about it. This effectively prevents the lead wire connecting the first lead wire 26 from rotating and knotting inside the housing when the first housing 11 is installed in, for example, the base of a handheld device 600. Furthermore, it prevents the cable from detaching from the circuit board inside the base or breaking.

[0045] In a preferred embodiment of this utility model, the limiting structure comprises a protrusion 14 and a groove 28 disposed between the first connector 22 and the housing 1. The groove 28 extends along the meridian direction of the outer wall of the connecting component 21 or the inner wall of the housing 1, and its extension length is greater than the length of the protrusion. This arrangement not only prevents the first connector 22 from rotating around its axis but also guides its swing direction, improving the stability of the swing. This limiting structure can be configured as one set or two sets, with the two sets positioned radially opposite each other to further enhance the guiding effect and thus improve the stability of the swing.

[0046] Furthermore, the extension length of the groove 28 is set to be less than the length of the outer wall surface of the connecting component 21 in the longitudinal direction, so as to limit the swing angle of the connecting component 21 within a certain angle. This certain angle is less than the angle between the axis of the connecting component 21 and the line connecting the center of the connecting component 21 to the inner edge of the second opening 120. This ensures that when the connecting component 21 swings, even if the second lead portion 27 swings to its maximum tilt angle, it will not abut against the inner wall surface of the second opening 120, avoiding collision or friction between the second lead portion 27 and the housing 1, and improving the service life of the entire wire connecting assembly 100. The center of the connecting component 21 refers to the center of the sphere of the connecting component 21.

[0047] like Figure 4 and Figure 5 As shown, in this embodiment, the groove 28 is disposed on the outer wall surface of the connecting assembly 21, and extends through the first connector 22 along the meridian direction to the second connector 23. On the second connector 23, the depth of the groove 28 gradually decreases near its end. The protrusion 14 protrudes from the inner wall surface of the first housing 11 and is disposed near the first opening 110. The protrusion 14 is wedge-shaped, with a smaller side near the first opening 110 and a relatively larger side away from the first opening 110, thereby minimizing its contact area with the groove 28 and avoiding interference with the inner wall of the groove 28 to the extent possible, thus affecting the swing of the connecting assembly 21.

[0048] Furthermore, the connecting component 21 has a central cross-section perpendicular to the axis of the first connector 22, and the aforementioned certain angle is no greater than the angle between the line connecting the center to the inner edge of the first opening 110 and the central cross-section. This restriction effectively prevents the maximum position of the center of the connecting component 21 from exceeding the first opening 110 when the component swings, thus preventing the connecting component 21 from detaching from the housing 2 through the first opening 110. The central cross-section refers to the cross-section passing through the center of the connecting component 21 and perpendicular to the axis of the first connector 22. In this embodiment, the center of the connecting component 21 is located on the plane where the first connector 22 and the second connector 23 meet.

[0049] Please continue reading. Figures 1 to 5 As shown, the first connector 22 and the second connector 23 are connected to each other along the axial direction of the first connector 22. In this embodiment, the first connector 22 and the second connector 23 are also nested at their mating parts, that is, the mating parts are both stepped. The first connector 22 is an inner step, and the second connector 23 is an outer step. The mating end of the second connector 23 is nested inside the mating end of the first connector 22, so that the first connector 22 and the second connector 23 form a limit in the direction perpendicular to the axial direction of the first connector 22. At the same time, the stepped design can also restrict the first connector 22 and the second connector 23 from moving towards each other.

[0050] Furthermore, this docking arrangement not only prevents axial and radial movement of the first connector 22 and the second connector 23, but also allows the second connector 23 to rotate along the inner stepped docking end of the first connector 22, ensuring rotational stability. In the docking direction of the first connector 22 and the second connector 23, the housing 2 restricts the movement, ensuring that the inner diameters of both the first opening 110 and the second opening 120 are smaller than the outer diameter of the connecting assembly 21.

[0051] Of course, as another embodiment of this utility model, a track groove extending in the circumferential direction can be provided on the outer or inner side of one of the first connecting member 22 and the second connecting member 23, and a protrusion that cooperates with the track groove can be provided on the other. By cooperating with the track groove, the first connecting member 22 and the second connecting member 23 can be relatively positioned in both radial and axial directions without affecting their relative rotation along the axis.

[0052] Regardless of the connection method, the outer walls of the first connector 22 and the second connector 23 are located on the same spherical surface, thereby ensuring smooth swinging or rotation within the accommodating cavity 10.

[0053] Furthermore, the aforementioned stepped docking design or track groove extends continuously along the circumference of the connecting component 21 and runs through the entire circumference, allowing the second connecting member 23 to rotate arbitrarily within a 360-degree range relative to the first connecting member 22. Of course, it is also feasible to set these structures intermittently so that the second connecting member 23 can rotate within a certain angle range.

[0054] Furthermore, such as Figures 3 to 5 As shown, the first connector 22 has a first body portion 221 and a first insertion portion 222 extending from the axis of the first body portion 221 toward the second connector 23.

[0055] In this embodiment, the first body portion 221 is designed in a bowl shape with its opening facing the second connector 23, and the side of it facing away from the second connector 23 is flat, so as to prevent the first connector 22 from protruding from the first opening 110 and reduce the volume of the wire connection assembly 100.

[0056] In this embodiment, the second connector 23 is not limited in size because it needs to lead the second lead portion 27 outward to connect the cable. Therefore, the second connector 23 is set in a hemispherical shape and protrudes outward from the second opening 120.

[0057] The first lead portion 26 and the first plug portion 222 extend in opposite directions from the axis of the first body portion 221. A recess 2211 is formed in the middle of the side of the first body portion 221 opposite to the second connector 23. The first lead portion 26 extends from the middle of the recess 2211 in a direction opposite to the second connector 23, such that the recess 2211 surrounds the first lead portion 26, and there is a certain gap between the inner wall of the recess 2211 and the first lead portion 26. Since the first lead portion 26 is connected to the circuit board inside the base of the handheld device 600 via a lead wire when the wire connection assembly 100 is installed, a certain length of the lead wire needs to be retained to prevent excessive pulling by the swinging wire assembly 2. The recess 2211 is thus formed as a space to accommodate the lead wire. Furthermore, the recess 2211 protruding towards the second connector 23 also enhances the strength of the first connector 22.

[0058] The second connecting portion 23 has a second body portion 231 and a second insertion portion 232 extending from the axis of the second body portion 231 toward the first connecting member 22. The first insertion portion 222 and the second insertion portion 232 have conductors that are connected opposite each other along the axial direction of the connecting assembly 21. The first lead portion 26 and the second lead portion 27 are both electrically connected to the conductors on the corresponding connecting members. With this arrangement, after the first connecting member 22 and the second connecting member 23 are connected to each other along the axial direction of the first connecting member 22, the first lead portion 26 and the second lead portion 27 are electrically connected through the first insertion portion 222 and the second insertion portion 232.

[0059] The second body portion 231 is bowl-shaped with an opening facing the first connector 22, and has a reinforcing wall 2312 that surrounds the outer wall 2311 of the second insertion portion 232 and is radially disposed between the outer wall 2311 and the second insertion portion 232. The reinforcing wall 2312 protrudes from the inner surface of the outer wall 2311 opposite to the first connector 22 toward the first connector 22 and is arranged in a ring to enhance the strength of the second connector 23 and ensure the service life of the wire connection assembly 100.

[0060] Furthermore, the first plug-in portion 222 has a columnar first support portion 2221, a first conductor 2222 disposed at the center of the first support portion 2221 and protruding toward the second connector 23, and a second conductor 2223 surrounding the periphery of the first support portion 2221. The first lead portion 26 is electrically connected to the first conductor 2222 and the second conductor 2223.

[0061] The second insertion portion 232 has a second support portion 2321 and a third conductor 2322 protruding from the second support portion 2321 toward the first insertion portion 222. The second support portion 2321 has an insertion groove 2323 for the first conductor 2222 to be inserted into and a fourth conductor 2324 disposed within the insertion groove 2323. The third conductor 2322 and the fourth conductor 2324 are insulated from each other through the second support portion 2321. The third conductor 2322 is arranged in a snap-fit ​​shape to snap-fit ​​with the second conductor 2223. The inner diameter of the third conductor 2322 is larger than the diameter of the first conductor 2222 and the insertion groove 2323, and slightly smaller than the outer diameter of the second conductor 2223 to ensure stable contact between the third conductor 2322 and the second conductor 2223. The second lead portion 27 is electrically connected to the third conductor 2322 and the fourth conductor 2324.

[0062] In addition, as a preferred embodiment of the present invention, a damping adjustment structure (not shown) can be provided between the second connector 23 and the housing 1. The damping adjustment structure can be adaptively set according to the material and roughness of the connecting component 21 and the housing 1, so that the flexibility of the second connector 23 when rotating in the housing 1 can be controlled.

[0063] Based on the above, it can be concluded that, combined with Figures 6 to 9 As shown, this utility model also relates to the handheld device 600. The handheld device 600 can be a device for hair care or other household devices, and includes a base 6 and a wire connection assembly 100 as described above. The wire connection assembly 100 is fixed inside the base 6 by a housing 2. The base 6 has a lead wire opening 60, and a second opening 120 communicates with the lead wire opening 60. At least a portion of the second connector 23 protrudes from the lead wire opening 60 from the base 6.

[0064] Specifically, the base 6 has a housing 61 with a receiving cavity 610, and a fastener 62 disposed within the housing 61 and fixed to the housing 2. The housing 61 can be the handle housing of a handheld device 600, and typically a cable is led out from the handle to connect to an external power interface.

[0065] like Figure 6 and Figure 9As shown, the housing 61 is hollow and cylindrical, with the lead wire opening 60 located at one end of the housing 61. The housing 61 has an end wall 611 located on a first end face adjacent to the second opening 120 of the housing 2, and a side wall 612 connected to the end wall 611 and confined to the periphery of the housing 2. The fixing member 62 has a first limiting portion 621 located on the side of the first housing 11 opposite to the second housing 12. Thus, the first limiting portion 621 and the end wall 611 confine the wire connection assembly 100 within the housing 61.

[0066] Furthermore, the fixing member 62 is also provided with a second limiting part 622 protruding toward the second housing 12 of the wire connection assembly 100. The second limiting part 622 passes through the outside of the first housing 11 and abuts against the stepped surface 126 on the outside of the second housing 12, so as to directly limit the relative position of the second housing 12 within the housing 61. The second limiting part 622 protrudes toward the slot 13 formed between the first housing 11 and the second housing 12 to form a locking block 623, so as to further cooperate to form a limiting and ensure the fixed stability of the wire connection assembly 100 within the housing 61.

[0067] The fastener 62 is also arranged in an annular column shape inside the housing 61, and includes a first fastener 624 and a second fastener 625 that are fixed to each other in the radial direction. A snap-fit ​​fastening structure is provided between the first fastener 624 and the second fastener 625, so that during installation, the first fastener 624 and the second fastener 625 can be installed from both sides of the housing 2 onto the wire connection assembly 100, and then fixed to each other by the snap-fit ​​fastening structure before being inserted together into the housing 61.

[0068] As can be seen from the above, this utility model allows the wire assembly 2 to be oscillatingly disposed within the housing 2, enabling the lead wire to be connected to the cable at an angle that can be changed according to usage requirements, thus avoiding the risk of the cable bending and causing the device to explode. Furthermore, by allowing the second connector 23 connecting the second lead wire 27 to rotate relative to the first connector 22, the second lead wire 27 can rotate with the force when subjected to circumferential rotational tension, thereby effectively preventing the cable connected to the second lead wire 27 from twisting or tangling, thus facilitating flexible use and improving the user experience.
