Description

Technical Field

[0001] The utility model relates to the technical field of slip rings, in particular to a transmission structure for a large-diameter slip ring for gigabit Ethernet. Background Art

[0002] A slip ring is one of the connectors, also known as a collecting ring or a current collector ring, which is used to achieve stable and reliable transmission of signals between two relatively rotating components, and is widely used in aviation, aerospace, military, medical, ship and industrial automation systems. Generally speaking, small-sized slip rings are adopted for slip rings transmitting medium- and high-frequency signals, but for some special systems, a hollow large-diameter slip ring must be used to transmit signals.

[0003] In traditional large-diameter slip rings, theoretically, when the input and output of the large-diameter slip ring are 180° apart, they are perfectly matched, and the insertion loss is 0 dB at this time. However, when the input and output of the large-diameter slip ring are relatively at 0°, the insertion loss will be very large, and the signal transmission performance near the 0° position will become very poor.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0024] In the embodiments of the present application, referring to Figure 1 and Figure 2 , it includes support washers 5. There are multiple support washers 5, and the multiple support washers 5 are stacked and connected together in sequence, and the entire transmission structure is installed in the multiple support washers 5; the support washers 5 are made of insulating material and have an insulating effect. At the same time, a plurality of through holes 8 are provided in the support washers 5, reducing the impedance of the transmission structure when transmitting signals, thereby improving the impedance characteristic matching degree of the signal transmission structure on the support washers 5 and enhancing the signal transmission intensity to a certain extent.

[0025] In the embodiments of the present application, referring to Figure 1 , Figure 3 and Figure 4 , an annular step 9 is provided on the upper end surface of each support washer 5 along the outer circumference, forming a stepped structure with a higher inner ring step and a lower outer ring step. A circle of through holes 8 is provided on the outer ring step of the annular step 9, and the conductive ring 2 is sleeved on the annular step 9; a brush bundle 3 is provided on the outer surface of the support washer 5, facilitating the electrical connection between the conductive ring 2 and the brush bundle 3. The brush bundle 3 is connected to a brush mounting plate 4, facilitating the stable transmission of signals;

[0026] The conductive ring 2 is also electrically connected to a round copper wire 1. The round copper wire 1 is set in a semi-circular arc shape. A semi-circular groove 10 is provided on the upper end surface of the inner ring step of the annular step 9, and the round copper wire 1 is installed in the groove 10. Both ends of the round copper wire 1 pass through the outer wall surface of the groove 10 and are connected to the conductive ring 2, so that there are two transmission points between the round copper wire 1 and the conductive ring 2, adding one more transmission point than before. When the slip ring rotates, the input end and the output end of the slip ring will not be in a completely relative 0° state, thereby also avoiding the reduction of the signal transmission intensity.

[0027] Referring to Figure 2, a groove 7 is provided on the inner side wall of the support washer 5 along the axial direction. The groove 7 is opened at the middle position of the round copper wire 1, and a signal transmission line 6 is welded in the groove 7. The signal transmission line 6 is fixedly connected to the middle position of the round copper wire 1, facilitating the transmission of signals to the round copper wire 1.

[0028] The working principle of this embodiment: The impedance of the signal transmission system during signal transmission is reduced through the multiple through holes 8 on the support washer 5, enhancing the signal transmission intensity to a certain extent;

[0029] Then, the round copper wire 1 receives the signal on the signal transmission line 6, and the signal is transmitted from the round copper wire 1 to the conductive ring 2 through two transmission points, so that the input end and the output end of the signal do not completely face each other at 0° during the rotation of the slip ring. Thus, the phenomenon of excessive weakening of the transmitted signal is avoided during the process of the entire signal being transmitted from the round copper wire 1 to the conductive ring 2. The conductive ring 2 then continues to lead out the signal to the brush bundle 3, enabling the brush bundle 3 to lead out the signal, thereby completing the entire signal transmission. When the slip ring rotates, there is always a continuous signal transmission, effectively improving the signal transmission stability during the rotation of the slip ring.

Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
