[0033] Example 1

[0034] like Figure 1 and 6 As shown, an embodiment of the present invention provides a conductive slip ring, which comprises a lower half shell 11 and an upper half shell 12 which are matched up and down to form a housing 1, and a limit plate 2 arranged in the housing 1, the lower half shell 11 and the upper half shell 12 can rotate relatively, and when the conductive slip ring is installed, the lower half shell 11 and the upper half shell 12 are respectively fixedly connected to two relatively rotating devices, and the lower half shell 11 and the upper half shell 12 are respectively provided with a threading hole A111 and a threading hole B121 for the wire to pass through; a plurality of lower conductive rings 112 are arranged concentrically at intervals along the radial direction on the inner wall of the lower half shell 11, and the wires inserted through the threading holes A111 are connected to the lower conductive rings 112; a plurality of upper conductive rings 122 are arranged concentrically at intervals along the radial direction on the inner wall of the upper half shell 12, and the wires inserted through the threading holes B121 are connected to the upper conductive rings 122, and the lower conductive rings 112 and The upper conductive rings 122 are all circular and arranged one by one opposite to each other; the limiting disk 2 is provided with an intermediate conductor 21 at a position corresponding to the lower conductive ring 112 and the upper conductive ring 122, the disk surface of the limiting disk 2 is perpendicular to the axis of the shell 1, and the intermediate conductor 21 is simultaneously in contact with the lower conductive ring 112 and the upper conductive ring 122 arranged opposite to each other; in this embodiment, a plurality of lower conductive rings 112 are arranged radially at intervals on the lower half shell 11 and a plurality of upper conductive rings 122 are arranged radially at intervals on the upper half shell 12, and the limiting disk 2 and the intermediate conductor 21 are arranged on the limiting disk 2, and the lower conductive ring 112 and the upper conductive ring 122 are connected correspondingly by the intermediate conductor 21, and the overall structure is a flat structure, which can effectively reduce the axial size of the conductive slip ring, is suitable for installation and use in a narrow space with a small installation spacing, and has good practicality.

[0035] In order to facilitate the installation of the intermediate conductor 21 on the limiting disk 2, a limiting hole 22 is provided on the disk surface of the limiting disk 2. The limiting hole 22 penetrates along the thickness direction of the limiting disk 2. The intermediate conductor 21 is arranged in the limiting hole 22. The limiting hole 22 can play an installation limiting role for the intermediate conductor 21 to prevent the intermediate conductor 21 from shifting.

[0036] In some embodiments, Figure 2 and Figure 5As shown, the lower conductive ring 112 is provided with a lower annular groove 113 on the side facing the limiting disk 2, and the upper conductive ring 122 is provided with an upper annular groove 123 on the side facing the limiting disk 2. The intermediate conductor 21 is spherical and its diameter is greater than the length of the limiting hole 22. The outer side of the intermediate conductor 21 contacts the inner side of the lower annular groove 113 and the upper annular groove 123. The setting of the lower annular groove 113 and the upper annular groove 123 can form a certain limiting effect on the intermediate conductor 21, and can increase the contact surface of the intermediate conductor 21 with the lower conductive ring 112 and the upper conductive ring 122, thereby enhancing the electrical conduction performance. It is preferred that the lower conductive ring 112, the upper conductive ring 122 and the intermediate conductor 21 are made of copper to ensure conductivity.

[0037] In order to enhance the positioning of the limit plate 2 and facilitate assembly, a positioning pin 13 is provided on the lower half shell 11 or the upper half shell 12 along the up and down directions, and a positioning hole 23 is provided on the limit plate 2 to be plugged into and cooperate with the positioning pin 13. The positioning pin 13 is inserted into the positioning hole 23 to form a limiting effect on the limit plate 2.

[0038] During the use of the conductive slip ring, there is continuous friction between the middle conductor 21 and the lower conductive ring 112 and the upper conductive ring 122, which may cause wear problems. Therefore, in order to ensure continuous good conduction performance, in this embodiment, the upper half shell 12 is arranged to be movable up and down relative to the lower half shell 11, and the lower half shell 11 and the upper half shell 12 are arranged to be connected by an elastic connection component 4, and the elastic connection component 4 is arranged in the up and down direction and has an elastic force that enables the lower half shell 11 to keep moving toward the upper half shell 12. Elastic compensation is provided by the elastic connection component 4. Under the elastic force of the elastic connection component 4, the middle conductor 21 and the lower conductive ring 112 and the upper conductive ring 122 always maintain good contact, thereby ensuring electrical conduction performance.

[0039] Specifically, Figures 3 to 5 As shown, the elastic connection component 4 includes a bolt 41, a sleeve 42, a nut 43 and a pressure spring 44. The lower half shell 11 is provided with a groove 14 and a bolt through hole 15 at the center. The nut 43 is embedded in the groove 14. The upper half shell 12 is provided with a mounting hole 16 at the center. The sleeve 42 is limitedly installed in the mounting hole 16 and a bearing 17 is limitedly installed between the sleeve 42 and the upper half shell 12. The upper half shell 12 can rotate relative to the lower half shell 11 through the bearing 17. The bolt 41 passes through the inner cavity of the sleeve 42 and the bolt through hole 15 and is threadedly matched with the nut 43. The pressure spring 44 is sleeved on the bolt 41. The elastic force generated by the pressure spring 44 keeps the sleeve 42 moving toward the lower half shell 11, so that the lower half shell 11 and the upper half shell 12 are always kept close to each other, thereby ensuring that the intermediate conductor 21 maintains close contact with the lower conductive ring 112 and the upper conductive ring 122.

[0040] In some embodiments, Figure 5 As shown, the outer periphery of the lower half shell 11 is provided with an annular convex plate 114 protruding toward the upper half shell 12 and a flat plate portion 115 protruding radially outward from the bottom of the annular convex plate 114, and the outer periphery of the upper half shell 12 is provided with an annular baffle 124 protruding toward the upper half shell 12 and sleeved on the outer side of the annular convex plate 114; further, the annular baffle 124 is provided with an annular lip 125 at the periphery of one end close to the flat plate portion 115, and the annular lip 125 forms an elastic contact with the corresponding side surface of the flat plate portion 115, and the cross-sectional shape of the annular lip 125 can be set to a triangle, a trapezoid or an arc, so that the annular lip 125 has good flexibility; the annular lip 125 Lubricating grease can be applied to the contact portion with the flat plate portion 115 to reduce the friction between the two. The gap between the lower half shell 11 and the upper half shell 12 can be blocked by the sleeve connection between the annular baffle 124 and the annular convex plate 114 and the elastic contact between the annular lip 125 and the flat plate portion 115, thereby preventing dust from entering the interior of the housing 1 through the gap and affecting the performance of the conductive slip ring. In addition, the contact between the annular lip 125 and the flat plate portion 115 can play a supporting role between the upper half shell 12 and the lower half shell 11, thereby enhancing the overall stability of the structure. A mounting structure is provided on the flat plate portion 115; illustratively, the mounting structure can be set as a fixing hole, which is fixedly connected to an external device through the fixing hole.

[0041] In order to effectively limit the bearing 17 and ensure the structural integrity, the end of the sleeve 42 away from the lower half shell 11 is provided with an outwardly protruding stop edge A421, and the inner edge of the mounting hole 16 is protrudingly provided with a stop edge B161, and the inner edge of the stop edge B161 is sleeved with the outer periphery of the sleeve 42, and the stop edge A421 and the stop edge B161 are arranged opposite to each other one above and one below, and a limiting space is formed between the stop edge A421 and the stop edge B161, and the bearing 17 is installed in the limiting space, and the inner and outer end edges of the bearing 17 are respectively abutted against the stop edge A421 and the stop edge B161, thereby limiting the up and down movement of the bearing 17.

[0042] In actual operation, considering that the contact parts between the intermediate conductor 21 and the upper conductive ring 122 and the lower conductive ring 112 are prone to generate heat and cause a high temperature rise, a heat dissipation structure can be added to the outer shell 1, specifically, a vent hole is set through the upper half shell 12 and / or the lower half shell 11, and the vent hole is set to be a conical hole with a larger inside and a smaller outside, and the outer port diameter of the conical hole is less than 2mm. Preferably, the outer port diameter of the conical hole is set to 0.5mm, 1mm, and 1.5mm. The conical hole structure is conducive to guiding the internal heat of the outer shell 1 to be discharged from the vent hole, which is not conducive to dust entering the outer shell 1 through the vent hole.

[0043] like Figure 5 and Figure 6As shown, the inner sides of the lower half shell 11 and the upper half shell 12 are respectively provided with a plurality of convex strips A116 and convex strips B126 uniformly distributed along the circumferential direction, the convex strips A116 and convex strips B126 are both extended radially, and the convex strips A116 and convex strips B126 are respectively provided with positioning grooves A117 and positioning grooves B127, the lower conductive ring 112 and the upper conductive ring 122 are respectively correspondingly embedded and positioned in the positioning grooves A117 and positioning grooves B127; through the positioning grooves A117 and B127, the lower conductive ring 112 and the upper conductive ring 122 are respectively correspondingly embedded and positioned in the positioning grooves A117 and B127; 17 and the positioning groove B127 can respectively limit the lower conductive ring 112 and the upper conductive ring 122; it is preferred to set the groove depth of the positioning groove A117 to be smaller than the protruding height of the convex strip A116, and the groove depth of the positioning groove B127 to be smaller than the protruding height of the convex strip B126, so that the lower conductive ring 112 and the upper conductive ring 122 can maintain a certain distance from the inner side surfaces of the lower half shell 11 and the upper half shell 12 after being respectively embedded in the positioning groove A117 and the positioning groove B127.

[0044] Example 2

[0045] This embodiment is basically the same as the above embodiments, except that the structure of the intermediate conductor 21 is as follows: Figure 7 and Figure 8 As shown, the intermediate conductor 21 in this embodiment includes a limiting sleeve 3 limitedly installed in the limiting hole 22, a conductor 31 arranged at both ends of the limiting sleeve 3 and a conductive spring 32 arranged in the limiting sleeve 3 and between the two conductors 31, the conductive spring 32 provides elastic forces in opposite directions for the two conductors 31, so that the two conductors 31 respectively keep in contact with the lower conductive ring 112 and the upper conductive ring 122; the two conductors 31 are connected through the conductive spring 32; the two conductors 31 are in contact with the lower conductive ring 112 and the upper conductive ring 122 respectively; the conductor 31 can be set to a sphere or a cylinder with an arc-shaped convex surface at the outer end; limiting stops can be set at both ends of the limiting sleeve 3, and the conductor 31 is limited by the limiting stops to prevent the conductor 31 from escaping from the limiting sleeve 3, so that the intermediate conductor 21 can be assembled as a whole and then loaded into the limiting hole 22 on the limiting disk 2.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
