DETAILED DESCRIPTION

[0021] The embodiments of the application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar methods or methods with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the application, and cannot be understood as a limitation of the application, and all other embodiments obtained by those skilled in the art without creative labor based on the embodiments in the application belong to the scope of protection of the application.

[0022] Please refer to Figs. 1-9, the embodiment of the application proposes a conductive slip ring winding device, which comprises a first connecting terminal 1 and a second connecting terminal 2; the first connecting terminal 1 comprises a first conductor 10 and an insulating inner shell 11; the first conductor 10 is arranged on one side of the insulating inner shell 11, the other side of the insulating inner shell 11 is provided with a conductive wire 3, and the conductive wire 3 is connected to the first conductor 10; the second connecting terminal 2 comprises a second conductor 20 and an insulating shell 21; the second conductor 20 is arranged on the insulating shell 21, the insulating shell 21 is rotatably connected with the fixed side of the first conductor 10 of the insulating inner shell 11, and the second conductor 20 is in elastic contact with the first conductor 10. For example, the second conductor 20 can comprise an elastic contact head 200, and the elastic contact head 200 is in elastic contact with the first conductor 10.

[0023] It should be noted that the first electrically conductive body 10 can be an electrically conductive coil or an electrically conductive spring; the second electrically conductive body 20 can be an electrically conductive spring or an electrically conductive coil. When the first electrically conductive body 10 is an electrically conductive coil, the second electrically conductive body 20 can be an electrically conductive spring; when the first electrically conductive body 10 is an electrically conductive spring, the second electrically conductive body 20 can be an electrically conductive coil.

[0024] It should be noted that in the prior art, two PCBs are used in the electrically conductive slip ring take-up device, namely a PCB with a PIN seat and a PCB with an electroplated layer. In the PCB with the PIN seat, the PIN seat needs to be welded on the PCB, and a spring is then welded on the PIN seat. One end of the wire is fixed on the PIN seat, and the spring on the PIN seat is in contact with the PCB with the electroplated layer to connect the electrical signal on the PCB with the electroplated layer, thereby realizing the conduction of the wire. The welding assembly of the PIN seat is difficult, and the manufacturing cost is high. The process of making the electroplated layer on the PCB is complex and not environmentally friendly. After long-term contact between the spring on the PIN seat and the PCB with the electroplated layer, the plating layer will be ground into powder and accumulated together, which can easily burn out the electrically conductive slip ring take-up device. In addition, the way of conducting electricity through the contact between the electroplated layer of the PCB and the spring has high impedance and small conduction area, and the temperature is easy to rise, which can easily damage the electrically conductive slip ring take-up device when conducting large current. In the present embodiment, the electrically conductive slip ring take-up device includes a first connecting terminal 1 and a second connecting terminal 2. The first electrically conductive body 10 of the first connecting terminal 1 is arranged on one side of the insulating inner shell 11, and the electrically conductive wire 3 is installed on the other side of the insulating inner shell 11. The electrically conductive wire 3 is connected to the first electrically conductive body 10. The second electrically conductive body 20 of the second connecting terminal 2 is arranged on the insulating outer shell 21. The insulating outer shell 21 is rotatably connected to the fixed side of the first electrically conductive body 10 of the insulating inner shell 11. The second electrically conductive body 20 is in elastic contact with the first electrically conductive body 10. The entire electrically conductive slip ring take-up device does not use a PCB, thereby eliminating the need to weld a PIN seat on the PCB and the need to weld a spring on the PIN seat to contact and conduct electricity with the electroplated layer on the PCB, thereby simplifying the assembly of the electrically conductive slip ring take-up device, avoiding the use of the PCB electroplating process, improving the environmental friendliness and efficiency of manufacturing the electrically conductive slip ring take-up device, avoiding the short circuit caused by the accumulation of powder due to the contact between the spring and the electroplated layer of the PCB, supporting large current conduction, and improving the safety and stability of the electrically conductive slip ring take-up device.

[0025] It should also be noted that in the present embodiment, the electrically conductive wire 3 is connected to the first electrically conductive body 10, and the elastic contact head 200 of the second electrically conductive body 20 is in contact with the first electrically conductive body 10, thereby realizing conduction. Moreover, the contact between the coil and the spring is the contact between rigid bodies and rigid bodies, which can withstand larger current values of large current compared to the contact between the spring and the electroplated layer of the PCB. The insulating outer shell 21 is rotatably connected to the fixed side of the first electrically conductive body 10 of the insulating inner shell 11, thereby allowing the insulating inner shell 11 to rotate on the insulating outer shell 21 and drive the winding and unwinding of the electrically conductive wire 3.

[0026] In further preferred embodiments, the shell surface of the first conductor 10 setting side of the insulating inner shell 11 is formed with a coil limiting groove 110, and the first conductor 10 is formed with a plurality of clamping protrusions 100, the first conductor 10 is limited in the coil limiting groove 110 and fixed with the sidewall of the coil limiting groove 110 through the plurality of clamping protrusions 100, thereby avoiding the first conductor 10 from being separated from the insulating inner shell 11, causing the failure of conductive connection or short circuit. Further, the shell surface of the first conductor 10 setting side of the insulating inner shell 11 is formed with a guide rail groove 116, which surrounds the outside of the coil limiting groove 110; the insulating outer shell 21 and the first conductor 10 fixed side of the insulating inner shell 11 are rotatably connected through the guide rail groove 116, thereby improving the smoothness of the rotation of the insulating inner shell 11 on the insulating outer shell 21.

[0027] In some preferred embodiments, the conductive slip ring take-up device further comprises an upper cover 4; after the insulating outer shell 21 and the first conductor 10 fixed side of the insulating inner shell 11 are connected as a whole, the upper cover 4 is clamped with the insulating outer shell 21, and the insulating inner shell 11 is assembled between the upper cover 4 and the insulating outer shell 21. It should be noted that in this embodiment, the upper cover 4 is clamped with the insulating outer shell 21, and the insulating inner shell 11 is assembled between the upper cover 4 and the insulating outer shell 21, which is simple to assemble, thereby reducing the manufacturing cost of the conductive slip ring take-up device.

[0028] In some preferred embodiments, the first conductor 10 is arranged on one side of the insulating inner shell 11 by means of integral molding with the insulating inner shell 11, and the second conductor 20 is arranged on the insulating outer shell 21 by means of integral molding with the insulating outer shell 21. It should be noted that in this embodiment, the first conductor 10 is arranged on one side of the insulating inner shell 11 by means of integral molding with the insulating inner shell 11, and the second conductor 20 is arranged on the insulating outer shell 21 by means of integral molding with the insulating outer shell 21, without using a PCB board, and thus without welding a PIN seat on the PCB board, and without welding a spring sheet on the PIN seat to contact and conduct electricity with the electroplated layer on the PCB board, thereby simplifying the assembly of the conductive slip ring take-up device, avoiding the use of PCB electroplating process, improving the environmental friendliness and efficiency of manufacturing the conductive slip ring take-up device, avoiding the powder accumulation short circuit caused by the spring sheet contacting the electroplated layer on the PCB board, supporting large current conduction, and improving the safety and stability of the conductive slip ring take-up device. The integral molding can be achieved by a mold. For example, the first conductor 10 is integrally molded with the insulating inner shell 11 by a mold. For another example, the second conductor 20 is integrally molded with the insulating outer shell 21 by a mold.

[0029] In some preferred embodiments, the first conductive body 10 is a copper coil, the insulating inner shell 11 is a plastic inner shell; the second conductive body 20 is a copper sheet, and the insulating outer shell 21 is a plastic outer shell. Further, the first conductive body 10 includes at least two first conductive bodies 10, the first conductive body 10 with a larger radius surrounds the first conductive body 10 with a smaller radius, and the different first conductive bodies 10 are spaced apart by a certain distance; the conductive wire 3 includes at least two conductive wires 3; the at least two conductive wires 3 are correspondingly connected to the at least two first conductive bodies 10; and the second conductive body 20 includes at least two second conductive bodies 20, the elastic contact head 200 of the at least two second conductive bodies 20 correspondingly contacts the at least two first conductive bodies 10. Preferably, the first conductive body 10 includes five first conductive bodies 10, the first conductive body 10 with a larger radius surrounds the first conductive body 10 with a smaller radius, and the different first conductive bodies 10 are spaced apart by a certain distance; the conductive wire 3 includes five conductive wires 3; the five conductive wires 3 are correspondingly connected to the five first conductive bodies 10; and the second conductive body 20 includes five second conductive bodies 20, the elastic contact head 200 of the five second conductive bodies 20 correspondingly contacts the five first conductive bodies 10.

[0030] It should be noted that the copper material has good electrical conductivity, and the contact between the body of the copper coil and the elastic contact head 200 of the second conductive body 20 of the copper material will not cause powder accumulation due to contact friction, resulting in short circuit. The insulating inner shell 11 and the insulating outer shell 21 are both made of plastic, which can be easily integrated with the copper coil or the second conductive body 20 of the copper material by mold opening technology. In addition, the at least two conductive wires 3 are correspondingly connected to the at least two first conductive bodies 10, and the elastic contact head 200 of the at least two second conductive bodies 20 correspondingly contacts the at least two first conductive bodies 10, so that the conductive connection and the use of the multiple conductive wires 3 can be realized in the same conductive slip ring take-up device. The first conductive body 10 with a larger radius surrounds the first conductive body 10 with a smaller radius, and the different first conductive bodies 10 are spaced apart by a certain distance, so that the short circuit between the coils can be avoided.

[0031] In some preferred embodiments, the five second conductors 20 are spaced from each other from inside to outside, and a part of the shell body of the second conductor 20 on the outside surrounds a part of the shell body of the second conductor 20 on the inside; the shell body width of the outermost second conductor 20 is wider than the shell body width of the innermost second conductor 20 and the shell body width of the three second conductors 20 between the outermost second conductor 20 and the innermost second conductor 20. It should be noted that the five second conductors 20 spaced from each other from inside to outside can correspond to the five first conductors 10 spaced at a certain distance, and since the first conductors 10 with larger radii in the five first conductors 10 surround the first conductors 10 with smaller radii, each second conductor 20 from outside to inside in the five second conductors 20 can correspond to a single first conductor 10 in the five first conductors 10 spaced from each other from outside to inside, respectively, to realize the conductive connection between each first conductor 10 and each second conductor 20. Since the five conductive wires 3 correspond to the five first conductors 10, the conductive connection between each conductive wire 3 and a first conductor 10 corresponding to the conductive connection between each first conductor 10 and a second conductor 20 corresponding to one can be realized. It should be noted that in the present embodiment, since the shell body width of the outermost second conductor 20 and the shell body width of the innermost second conductor 20 are both wider than the shell body width of the three second conductors 20 between the outermost second conductor 20 and the innermost second conductor 20, the outermost second conductor 20 and the innermost second conductor 20 can withstand larger current value of large current, and the adaptability of the conductive slip ring take-up device is improved.

[0032] In some preferred embodiments, the width of the elastic contact head 200 of the outermost second conductor 20 and the width of the elastic contact head 200 of the innermost second conductor 20 are both wider than the width of the elastic contact head 200 of the three second conductors 20 between the outermost second conductor 20 and the innermost second conductor 20. It should be noted that in the present embodiment, since the width of the elastic contact head 200 of the outermost second conductor 20 and the width of the elastic contact head 200 of the innermost second conductor 20 are both wider than the width of the elastic contact head 200 of the three second conductors 20 between the outermost second conductor 20 and the innermost second conductor 20, the outermost second conductor 20 and the innermost second conductor 20 can withstand larger current value of large current (for example, current of over 3A or 5A), and the adaptability of the conductive slip ring take-up device is improved.

[0033] In some preferred embodiments, the elastic contact head 200 of the second conductor 20 comprises at least three elastic contact heads 200 which are spaced apart on the second conductor 20; the at least three elastic contact heads 200 are in extrusion contact with three different positions on the circumference of the first conductor 10, so that the second conductor 20 can always keep in contact with the first conductor 10 when the first conductor 10 rotates. It should be noted that in the present embodiment, the at least three elastic contact heads 200 are in extrusion contact with three different positions on the circumference of the first conductor 10, so that the second conductor 20 can always keep in contact with the first conductor 10 when the first conductor 10 rotates, thereby avoiding the second conductor 20 from intermittently separating from the first conductor 10 when the insulating inner shell 11 and the first conductor 10 rotate, resulting in poor electrical signal contact. Among them, when the at least three elastic contact heads 200 on the second conductor 20 are spaced apart, for example, they can be spaced apart in the manner of being distributed at the three vertices of a triangle.

[0034] In further some preferred embodiments, the second conductor 20 is irregular hook-shaped, the second conductor 20 comprises an external electrical signal line connecting end 201, the external electrical signal line connecting end 201 is a flat welding surface, thereby facilitating the welding of the second conductor 20 with the external electrical signal line, facilitating the setting of multiple elastic contact heads 200 on the second conductor 20 to contact different positions of the first conductor 10, improving the reliability of the contact. Further, the insulating shell 21 is provided with a welding line step 210, the external electrical signal line connecting end 201 of the second conductor 20 extends to the welding line step 210, thereby further improving the convenience of welding the second conductor 20 with the external electrical signal line.

It should be noted that in the present embodiment, the positioning hole 211 is beneficial to positioning the external electrical signal line connecting end 201, and the contact head movable hole 212 is beneficial to the free depression and rebound of the elastic contact head 200, extruding and contacting the first conductor 10. Further, the outer side of the insulating shell 21 is attached with a protective sticker 5, the protective sticker 5 covers the positioning hole 211 and the contact head movable hole 212, thereby not only increasing the aesthetic degree of the insulating shell 21, but also preventing dust from accumulating in the positioning hole 211 and the contact head movable hole 212, affecting the conductive connection between the second conductor 20 and the first conductor 10.
