Description

Technical Field

[0001] The present invention relates to the field of connectors, and in particular to an electrical connector. Background Art

[0002] Signal connection is a key link in achieving information interaction and collaborative work between devices. In electronic equipment, communication systems and many industrial control fields, different types of electrical connectors are widely used for signal connection.

[0003] In the existing technology involving signal connection using a conical surface structure, a common approach is to use a specially designed plug and socket structure. The plug is usually designed in a conical shape, and the socket has a matching conical cavity.

[0004] However, it is difficult for the conical connector in the prior art to ensure that the signal connection can be maintained continuously and stably after the conical plug contacts the conical socket in any posture, or when the conical plug is offset within a certain axial and radial range. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems in the related art to a certain extent. To this end, the present invention provides an electrical connector that has the advantages of being able to achieve blind insertion and maintain a stable electrical connection.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: An electrical connector includes a first connecting end and a second connecting end, the first connecting end including a shell and a tapered plug-in cavity formed in the shell, the second connecting end including a tapered plug-in portion, the tapered plug-in portion and the tapered plug-in cavity being plugged in or separated from each other along a plug-in direction so as to be electrically connected or disconnected, a fixed portion and a floating portion floatingly installed on the fixed portion are provided in the shell, the tapered plug-in cavity is formed in the floating portion, and the tapered plug-in portion can float relative to the fixed portion in a direction perpendicular to the plug-in direction under the action of the floating portion when plugged in the tapered plug-in cavity; the floating portion includes a floating component and a first connecting component with an elastic expansion amount, the floating component is floatingly connected to the fixed portion through the first connecting component, and the first connecting component expands and contracts in a direction perpendicular to the plug-in direction and abuts against the floating component.

[0007] In the present application, the conical plug-in portion of the second connection end is plugged into the conical plug-in cavity of the first connection end to achieve electrical connection or disconnection. The conical plug-in cavity is formed on the floating portion, that is, the conical plug-in cavity can also float relative to the fixed portion. Then, when the first connection end and the second connection end are blindly plugged together, the plug-in position of the conical plug-in portion relative to the conical plug-in cavity can be adjusted by the floating portion so that the conical plug-in portion is aligned with the conical plug-in cavity to achieve effective plug-in and conduction. In addition, the conical plug-in portion and the conical plug-in cavity can achieve stable contact through automatic guidance of the conical surface without precise alignment. Thus, under the action of the floating portion of the floating installation, the conical plug-in portion floats relative to the shell in a direction perpendicular to the plug-in direction, so that the conical plug-in portion can be smoothly plugged in after docking with the conical plug-in cavity in any posture, and after the plug-in is completed, when the conical plug-in portion is offset, the floating portion can adaptively adjust the position of the conical plug-in cavity to maintain a stable signal connection. In addition, the tapered plug-in portion and the tapered plug-in cavity can remain coaxial under the action of the floating portion. The floating portion allows a certain degree of fine-tuning or offset of the tapered plug-in portion and the tapered plug-in cavity when they are matched, but at the same time can guide the two back to the correct coaxial position.

[0008] Optionally, the floating assembly includes a floating block and a floating shell fixed to the floating block, the floating block is connected to the fixed part through the first connecting assembly, the floating shell is constructed as a hollow structure and the conical plug-in cavity is arranged in the floating shell.

[0009] By floating the floating block and setting the tapered plug-in cavity in the floating shell, the floating of the tapered plug-in cavity is achieved, which can not only significantly improve the plug-in alignment efficiency and reduce the impact of assembly errors on electrical contact, but also automatically correct the offset and buffer mechanical stress under vibration or impact conditions, thereby extending the life of the connector and reducing maintenance costs.

[0010] Optionally, the first connecting component includes a first push rod and a first bracket fixed to the fixed part, the first bracket extends in a direction perpendicular to the plug-in direction and has a clearance channel along its own extension direction, one end of the first push rod abuts against the floating block, and the other end is slidably disposed in the clearance channel.

[0011] The first bracket extends in a direction perpendicular to the plug-in direction, and the first bracket is provided with a makeshift channel. One end of the first push rod abuts the floating block, and the other end slides in the makeshift channel to provide a linear guide path for the floating block, ensuring that the floating direction is controllable, avoiding deflection or rotation during the floating process, and improving the movement accuracy.

[0012] Optionally, the first connecting assembly further includes a first spring, one end of the first spring abuts against the first push rod, and the other end of the first spring abuts against the bottom wall of the clearance channel.

[0013] The first spring realizes dynamic regulation of the floating block through elastic force. When the first spring is subjected to force and offset, it can store energy for buffering and automatically reset, automatically pushing the floating block to adjust its position to compensate for the error, ensuring that the tapered plug-in cavity and the tapered plug-in part are always plugged in. In addition, the elastic force of the first spring can absorb plug-in deviation or vibration impact energy, significantly improving the connection stability and overload resistance.

[0014] Optionally, the fixing portion is circular in structure, the first connecting components are configured into three groups, and the three groups of the first connecting components are evenly distributed along the circumference of the fixing portion.

[0015] The three groups of connection components are evenly distributed along the circumference to share the offset load of the floating block, significantly reducing the risk of single-point force concentration and avoiding tilting or jamming of the floating block. At the same time, multiple groups of elastic forces form triangular constraints in space, which can not only buffer vibration impact and drive the floating block to accurately reset, but also suppress yaw rotation to ensure that the floating shell remains relatively stable.

[0016] Optionally, one end of the floating shell away from the fixed part is connected to the shell through a second connecting assembly, and the second connecting assembly includes a second push rod fixed to the floating shell and a second bracket fixed to the shell, and a second spring is abutted between the second push rod and the second bracket to enable the second push rod to float in a direction perpendicular to the plug-in direction.

[0017] Through the coordinated cooperation of the second push rod, the second bracket and the second spring in the second connecting assembly, an elastic floating support structure is constructed between the end of the floating shell away from the fixed part and the shell: the elastic force of the second spring enables the second push rod to float relative to the second bracket in a direction perpendicular to the plug-in direction, that is, the end of the floating shell away from the fixed part also has dynamic adjustment capabilities, thereby compensating for the position deviation generated during the plug-in process, and buffering external vibration or impact loads, avoiding rigid collision or stress concentration between the floating shell and the shell; at the same time, the second spring ensures that the floating shell can automatically reset to the equilibrium position after being subjected to force, maintains stability between it and the shell, and significantly improves the adaptability of the floating shell.

[0018] Optionally, a connecting rod protruding from the body of the floating shell is formed at one end of the floating shell close to the floating block, a mounting hole is formed in the middle of the floating block, and the connecting rod passes through the fixing portion and is fixed to the mounting hole.

[0019] A rigid connection is formed between the connecting rod protruding from the end of the floating shell and the mounting hole in the middle of the floating block, thereby realizing synchronous floating of the floating shell and the floating block. The connecting rod passes through the fixed part and is fixed to the mounting hole, directly transmitting the floating motion of the floating block to the floating shell, ensuring the synchronization of the displacement of the two in the direction perpendicular to the plug-in direction, and avoiding uneven local force on the floating shell.

[0020] Optionally, the floating portion further includes a third spring, an annular flange is formed on the outer circumference of the floating shell, one end of the third spring abuts against the annular flange, and the other end abuts against a side of the fixing portion close to the annular flange.

[0021] One end of the third spring abuts the annular flange and the other end abuts the fixed part, forming an elastic preload along the plug-in direction, which allows the floating shell to float flexibly in a direction perpendicular to the plug-in direction to compensate for the deviation, and limits the maximum floating stroke through spring compression to avoid excessive deviation and structural interference; at the same time, the third spring can buffer vibration impact and suppress shaking or deflection during floating, significantly improving the dynamic stability of the floating system.

[0022] Optionally, a spring pin assembly is distributed on the outer surface of the floating shell, and a slip ring assembly for electrically connecting to the spring pin assembly is installed on the conical plug-in portion.

[0023] The floating housing's outer surface is connected to the tapered slip ring assembly by distributed spring pins, improving the reliability of the floating electrical connection. The spring pins are evenly distributed across the floating housing's surface in multiple contact points, forming adaptive electrical contact with the tapered slip ring assembly.

[0024] Optionally, the slip ring assembly includes a slip ring frame, a slip ring body embedded in the slip ring frame, and a rubber sleeve installed in the slip ring frame, a welding cup is provided at one end of the slip ring body extending into the rubber sleeve, a guide groove is provided in the slip ring frame, and the rubber sleeve is formed with a guide rib that can slide along the guide groove.

[0025] The sliding fit between the guide groove and the guide rib provides precise positioning for the rubber sleeve, making it easier to install the rubber sleeve. After the inside of the rubber sleeve is filled with epoxy glue, the bonding strength between the rubber sleeve and the slip ring body is enhanced by curing the glue, and the insulation of the epoxy glue is used to ensure the safety of the electrical connection.

[0026] Optionally, a connecting shaft is provided at the end of the conical plug-in portion, the slip ring skeleton is sleeved on the connecting shaft, the conical plug-in portion is provided with an anti-rotation boss, and the slip ring skeleton is provided with an anti-rotation groove for the anti-rotation boss to extend into.

[0027] The slip ring skeleton is sleeved on the connecting shaft of the tapered plug-in part to ensure the coaxiality of the slip ring assembly and the plug-in part, reducing the risk of contact wear or signal fluctuation caused by eccentricity; the anti-rotation boss extends into the anti-rotation groove of the slip ring skeleton to limit the relative rotation between the two, avoiding the electrical contact deviation between the slip ring body and the spring pin assembly due to vibration or external force, and ensuring the stability of electrical signal transmission.

[0028] Optionally, a fixing nut for tightening the slip ring frame is installed on one end of the connecting shaft away from the slip ring frame.

[0029] The fixing nut is tightened on the end of the connecting shaft away from the slip ring frame, applying axial preload to firmly clamp the slip ring frame in the tapered plug-in part to suppress shaking or deviation and improve the overall rigidity and impact resistance of the structure.

[0030] Optionally, the shell is provided with a first wire hole, and the tapered plug-in portion is provided with a second wire hole.

[0031] The first wire hole is opened in the shell, providing a fixed path for the external wire, facilitating electrical connection with the spring pin assembly, while preventing the wire from interfering with the shell during the floating process; the second wire hole is opened in the tapered plug-in part to guide the internal wire to connect with the solder cup.

[0032] These features and advantages of the present invention will be further disclosed in the following detailed description and accompanying drawings.

DETAILED DESCRIPTION

[0035] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described in the embodiments are intended to explain the present invention and are not to be construed as limiting the present invention.

[0036] Reference in this specification to "one embodiment," "an example," or "an example" means that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment of the present patent disclosure. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

[0037] Example: like Figures 1 to 3 As shown, this embodiment provides an electrical connector, including a first connecting end 1 and a second connecting end 2, the first connecting end 1 including a shell 11 and a tapered plug-in cavity 1321 formed in the shell 11, the second connecting end 2 including a tapered plug-in portion 21, the tapered plug-in portion 21 and the tapered plug-in cavity 1321 are plugged in or separated from each other along the plug-in direction so as to be electrically connected or disconnected, a fixed portion 12 and a floating portion 13 floatingly mounted on the fixed portion 12 are provided in the shell 11, the tapered plug-in cavity 1321 is formed in the floating portion 13, and when the tapered plug-in portion 21 is plugged in the tapered plug-in cavity 1321, it can float relative to the fixed portion 12 in a direction perpendicular to the plug-in direction under the action of the floating portion 13; the floating portion 13 includes a floating component and a first connecting component 133 with elastic expansion and contraction, the floating component is floatingly connected to the fixed portion 12 through the first connecting component 133, and the first connecting component 133 expands and contracts in a direction perpendicular to the plug-in direction and abuts against the floating component.

[0038] In this embodiment, the floating portion 13 is capable of floating relative to the fixed portion 12, and the tapered insertion cavity 1321 is formed in the floating portion 13, meaning that the tapered insertion cavity 1321 is also capable of floating relative to the fixed portion 12. Combined with the tapered surface-guided insertion structure of the tapered insertion portion 21 and the tapered insertion cavity 1321, a reliable connection between the first connection end 1 and the second connection end 2 in the insertion direction is achieved, while allowing a certain degree of floating perpendicular to the insertion direction. Therefore, when the first connection end 1 and the second connection end 2 are blind-mated, the insertion position of the tapered insertion portion 21 relative to the tapered insertion cavity 1321 is automatically adjusted to align the tapered insertion portion 21 with the tapered insertion cavity 1321, achieving effective insertion and conduction. In other words, the tapered insertion portion 21 can be smoothly mated with the tapered insertion cavity 1321 in any position. Furthermore, after mating, if the tapered insertion portion 21 deviates, the floating portion 13 can adaptively adjust the position of the tapered insertion cavity 1321 to maintain a stable signal connection.

[0039] Along the plug-in direction, the tapered plug-in cavity 1321 and the tapered plug-in end become increasingly thinner. When the tapered plug-in portion 21 of the second connection end 2 gradually approaches the shell 11 of the first connection end 1 along the plug-in direction, the tapered plug-in portion 21 begins to enter the tapered plug-in cavity 1321. Due to the tapered surface design of the tapered plug-in cavity 1321 and the tapered plug-in portion 21, during the plug-in process, if there is a centering deviation perpendicular to the plug-in direction, the floating portion 13 will be pushed by the tapered plug-in portion 21 and float adjusted relative to the fixed portion 12 in a direction perpendicular to the plug-in direction until the tapered plug-in portion 21 is fully inserted into the tapered plug-in cavity 1321 and an electrical connection is achieved. When the electrical connector needs to be disconnected, the tapered plug-in portion 21 of the second connection end 2 gradually withdraws from the tapered plug-in cavity 1321 in the opposite direction of the plug-in direction, and the first connection end 1 and the second connection end 2 are completely separated.

[0040] It should be noted that in this embodiment, the first connection end 1 refers to the socket of the electrical connector, and the second connection end 2 refers to the plug of the electrical connector. In addition, in this embodiment, the direction of the arrow X represents the "connection direction of the first connection end 1 and the second connection end 2."

[0041] like Figure 2 and Figure 3 As shown, the floating assembly includes a floating block 131 and a floating shell 132 fixed to the floating block 131. The floating block 131 is connected to the fixed part 12 through a first connecting assembly 133. The floating shell 132 is constructed as a hollow structure and a tapered plug-in cavity 1321 is set in the floating shell 132.

[0042] In this embodiment, the floating portion 13 consists of a floating block 131 and a floating shell 132. The floating block 131 is in a floating connection with the fixed portion 12, allowing the floating portion 13 to float in a direction perpendicular to the insertion direction. The floating shell 132 is hollow and defines a tapered insertion cavity 1321. When the tapered insertion portion 21 is inserted, the floating capacity of the floating portion 13 automatically compensates for misalignment caused by manufacturing errors, assembly deviations, vibration, thermal deformation, and other factors during operation, ensuring a secure fit between the tapered insertion portion 21 and the tapered insertion cavity 1321. Specifically, the floating shell 132 is conical in shape, with the hollow structure of the floating shell 132 forming the tapered insertion cavity 1321. In other embodiments, the floating shell 132 can also be cylindrical, as long as the insertion cavity is tapered.

[0043] The first connecting component 133 includes a first push rod 1331 and a first bracket 1332 fixed to the fixed part 12. The first bracket 1332 extends in a direction perpendicular to the plug-in direction and has a clearance channel 1332a along its own extension direction. One end of the first push rod 1331 abuts against the floating block 131, and the other end is slidably arranged in the clearance channel 1332a.

[0044] In this embodiment, the floating block 131 is connected to the fixed portion 12 in a floating manner via a first connecting assembly 133. The first push rod 1331 and first bracket 1332 in the first connecting assembly 133 cooperate to guide and constrain the floating movement of the floating block 131 perpendicular to the insertion direction. When the tapered insertion portion 21 is mated with the tapered insertion cavity 1321, if there is any misalignment perpendicular to the insertion direction, the floating block 131, driven by the tapered insertion portion 21, drives the first push rod 1331 to slide within the clearance channel 1332a of the first bracket 1332, achieving floating compensation and ensuring a smooth fit between the tapered insertion portion 21 and the tapered insertion cavity 1321.

[0045] The first connecting assembly 133 further includes a first spring. One end of the first spring abuts against the first push rod 1331 , and the other end of the first spring abuts against the bottom wall of the clearance channel 1332 a .

[0046] In this embodiment, when the floating block 131 deviates from its initial position due to external forces (such as insertion deviation or vibration), the compression or extension of the first spring stores elastic potential energy, which is automatically released when the external force disappears, driving the first push rod 1331 and the floating block 131 to return to their original position along a predetermined path. Simultaneously, while the force is continuously applied, the elastic force of the first spring continuously acts on the first push rod 1331, dynamically adjusting the position of the floating block 131 to compensate for the error and ensure that the tapered insertion cavity 1321 maintains stable contact with the tapered insertion portion 21. The diameter of the clearance channel 1332a is slightly larger than the diameter of the first push rod 1331.

[0047] The fixing portion 12 is circular in shape, and the first connecting components 133 are configured into three groups. The three groups of first connecting components 133 are evenly distributed along the circumference of the fixing portion 12 .

[0048] In this embodiment, the fixed portion 12 is circular in shape, with three sets of first connecting components 133 evenly distributed along its circumference. This ensures uniform support and guidance for the floating block 131 in all directions perpendicular to the insertion direction. The floating block 131 has three curved sidewalls corresponding to the positions of the first connecting components 133. When the floating block 131 moves due to external forces (such as lateral forces generated by insertion misalignment), these curved sidewalls continuously abut the ends of the first push rods 1331. Due to the curved surface characteristics of the curved sidewalls, during movement, the floating block 131 transmits force to the first push rods 1331 along an arc-shaped trajectory, thereby driving the first push rods 1331 to extend and retract in a specific direction perpendicular to the insertion direction. When the tapered insertion portion 21 is mated with the tapered insertion cavity 1321, if there is any misalignment perpendicular to the insertion direction, regardless of the direction of the misalignment, the at least one set of first connecting components 133 can guide the floating block 131 in the corresponding direction. Of course, in other embodiments, the first connecting components 133 can also be configured as 2 groups, 4 groups, 5 groups, etc., and multiple groups of first connecting components 133 may not be evenly distributed along the circumference of the fixing portion 12, and the fixing portion 12 may also be irregular, rectangular, etc.

[0049] One end of the floating shell 132 away from the fixed part 12 is connected to the shell 11 through a second connecting component 134. The second connecting component 134 includes a second push rod 1341 fixed to the floating shell 132 and a second bracket 1342 fixed to the shell 11. A second spring is abutted between the second push rod 1341 and the second bracket 1342 to enable the second push rod 1341 to float in a direction perpendicular to the plug-in direction.

[0050] In this embodiment, a second connecting assembly 134 is disposed between the floating housing 132 and the housing 11. The cooperation of a second push rod 1341, a second bracket 1342, and a second spring enables the floating housing 132 to not only float the end of the floating portion 13 closer to the fixed portion 12, driven by the floating block 131 connected to the fixed portion 12, but also allows the floating housing 132 to float further away from the fixed portion 12, via the second connecting assembly 134. When the tapered insert 21 is inserted into the tapered insertion cavity 1321 of the floating housing 132, regardless of the direction of centering deviation, the coordinated action of the first connecting assembly 133 and the second connecting assembly 134 guides the floating housing 132 to achieve multi-directional floating compensation, ensuring a secure fit between the tapered insert 21 and the tapered insertion cavity 1321.

[0051] like Figure 3 and Figure 4As shown, a connecting rod 1322 protruding from the body of the floating shell 132 is formed at one end of the floating shell 132 close to the floating block 131 , and a mounting hole 1311 is formed in the middle of the floating block 131 . The connecting rod 1322 passes through the fixing portion 12 and is fixed to the mounting hole 1311 .

[0052] In this embodiment, a protruding connecting rod 1322 is provided on one end of the floating housing 132, adjacent to the floating block 131. A mounting hole 1311 is provided in the center of the floating block 131. Connecting rod 1322 extends through the fixed portion 12 and is secured to mounting hole 1311 via fasteners such as screws, thereby connecting the floating housing 132 to the floating block 131. When the electrical connector is misaligned during insertion, the floating housing 132 is subjected to lateral forces. The connection between connecting rod 1322 and the floating block 131 causes the floating block 131 to move relative to the fixed portion 12.

[0053] The floating portion 13 further includes a third spring 135 . An annular flange 1323 is formed on the outer circumference of the floating housing 132 . One end of the third spring 135 abuts against the annular flange 1323 , and the other end abuts against a side of the fixed portion 12 close to the annular flange 1323 .

[0054] In this embodiment, one end of the third spring 135 abuts against the annular flange 1323 on the outer circumference of the floating shell 132, and the other end abuts against the side of the fixed portion 12 near the annular flange 1323. When the floating shell 132 moves, the third spring 135 is compressed or stretched, generating an elastic force. This elastic force not only provides elastic cushioning for the floating shell 132 but also helps the floating shell 132 return to a balanced position.

[0055] like Figure 4 and Figure 5 As shown, a spring pin assembly 1324 is distributed on the outer surface of the floating shell 132 , and a slip ring assembly 22 for electrical connection with the spring pin assembly 1324 is installed on the tapered plug-in portion 21 .

[0056] In this embodiment, spring pin assemblies 1324 distributed on the outer surface of the floating housing 132 provide electrical connection to the tapered connector 21 and slip ring assembly 22, enhancing the reliability of the floating electrical connection. These assemblies 1324 are evenly distributed across the surface of the floating housing 132, forming adaptive electrical contact with the tapered connector 21 and slip ring assembly 22. Specifically, the spring pin assemblies 1324 include three rows of five spring pins each, resulting in 15 spring pin assemblies 1324 distributed across the surface of the floating housing 132.

[0057] like Figure 5 and Figure 6As shown, the slip ring assembly 22 includes a slip ring frame 221, a slip ring body 222 embedded in the slip ring frame 221, and a rubber sleeve 223 installed in the slip ring frame 221. A welding cup 2221 is provided at one end of the slip ring body 222 extending into the rubber sleeve 223. A guide groove 2212 is provided in the slip ring frame 221, and the rubber sleeve 223 is formed with a guide rib 2231 that can slide along the guide groove 2212.

[0058] In this embodiment, by providing a guide groove 2212 within the slip ring skeleton 221 and forming a matching guide rib 2231 on the rubber sleeve 223, the rubber sleeve 223 can be positioned and installed within the slip ring skeleton 221, simplifying the installation process. A welding cup 2221 is provided at one end of the slip ring body 222 that extends into the rubber sleeve 223 to facilitate subsequent welding operations. The rubber sleeve 223 is filled with epoxy glue. On the one hand, after the epoxy glue is cured, it can enhance the bonding strength between the rubber sleeve 223 and the slip ring body 222, making the two tightly connected; on the other hand, the excellent insulation properties of the epoxy glue can effectively isolate the slip ring body 222, prevent current from being conducted in unintended paths, and ensure the safety of the electrical connection. The slip ring body 222 is constructed as an annular structure. The annular structure allows the slip ring body 222 to rotate relative to or float at any angle without the need to preset a specific direction, avoiding jamming or interference caused by axial or radial offset. Floating connection can be achieved without strict alignment, reducing assembly difficulty. In addition, the annular structure can ensure that the contact surface of the slip ring body 222 and the spring pin always maintain 360° continuous contact, avoiding signal interruption due to rotation or floating.

[0059] The end of the conical plug-in part 21 is provided with a connecting shaft 211, and the slip ring skeleton 221 is sleeved on the connecting shaft 211. The conical plug-in part 21 is provided with an anti-rotation boss 212, and the slip ring skeleton 221 is provided with an anti-rotation groove 2211 for the anti-rotation boss 212 to extend into.

[0060] In this embodiment, a connecting shaft 211 is provided at the end of the tapered plug-in portion 21 to provide a mounting base for the slip ring frame 221, allowing the slip ring frame 221 to be sleeved on the connecting shaft 211 for initial positioning. The anti-rotation boss 212 cooperates with the anti-rotation groove 2211 to prevent the slip ring frame 221 from rotating on the connecting shaft 211, ensuring the stability of the relative position of the slip ring frame 221 and the tapered plug-in portion 21, and preventing poor contact between the spring pin assembly 1324 and the slip ring assembly 22 due to rotation.

[0061] like Figure 5 As shown, a fixing nut 213 for pressing against the slip ring frame 221 is installed at one end of the connecting shaft 211 away from the slip ring frame 221 .

[0062] In this embodiment, a fixing nut 213 is installed at the end of the connecting shaft 211 away from the slip ring skeleton 221. By tightening the fixing nut 213, an axial pressing force is applied to the slip ring skeleton 221 to prevent the slip ring skeleton 221 from axially moving on the connecting shaft 211. Combined with the previous anti-rotation boss 212 and the anti-rotation groove 2211 to prevent rotation, the installation stability of the slip ring skeleton 221 on the tapered plug-in portion 21 is guaranteed.

[0063] The housing 11 defines a first wire hole, and the tapered plug-in portion 21 defines a second wire hole.

[0064] In this embodiment, the first wire hole is opened in the shell 11 to provide a fixed path for the external wire, which is convenient for electrical connection with the spring pin assembly 1324 and prevents the wire from interfering with the shell 11 during the floating process; the second wire hole is opened in the tapered plug-in portion 21 to guide the internal wire to connect with the solder cup 2221.

[0065] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
