Description

Technical Field

[0001] This utility model relates to the field of switch equipment technology, and in particular to a terminal adapter structure and a switch. Background Technology

[0002] In existing technologies, switches typically have multiple interfaces for connecting different communication lines. However, once these communication lines are connected, the switch needs to be placed in a location that does not obstruct or interfere with users. These locations are usually corners or other confined spaces. When the switch is placed in these areas, the large number of communication lines and limited space can easily lead to the connectors being squeezed or damaged, resulting in a reduced lifespan. Utility Model Content

[0003] The main purpose of this utility model is to propose a terminal adapter structure and switch, which aims to solve the technical problem that when the switch is placed in a corner or other relatively small space, the number of communication lines is large and the space is limited, which can easily lead to the joint position being squeezed and affected, resulting in a decrease in service life.

[0004] To achieve the above objectives, this utility model proposes an end-fitting structure, comprising:

[0005] The end cap body has a slot with an opening at one end. The end of the end cap body facing away from the opening is arc-shaped and forms a contact surface. A rotating shaft is provided on each of the two side walls of the end cap body near the contact surface. Mounting holes are formed on the side walls containing the two rotating shafts, spaced apart from the shafts and extending into the end cap body. The end cap body can be rotatably connected to an external electrical device via the rotating shafts, and the contact surface can be electrically connected to the external electrical device.

[0006] Two self-locking mechanisms are provided, with one self-locking mechanism installed in each of the mounting holes. The self-locking mechanisms can extend or retract along the mounting holes.

[0007] The end body can rotate on the external electrical device via the rotating shaft, and when the end body stops rotating, the self-locking mechanism locks the end body to the external electrical device.

[0008] In one embodiment, the self-locking mechanism includes:

[0009] A reset element, wherein the reset element is installed within the mounting hole; and

[0010] A locking element is connected to a reset element, and the reset element can drive the locking element to extend or retract from the mounting hole.

[0011] In one embodiment, the mounting hole includes an interconnected mounting section and a limiting section, the reset member is mounted on the mounting section, the limiting section is tapered away from the mounting section, and the locking member is a steel ball, which is movably mounted on the limiting section.

[0012] In one embodiment, the two mounting holes are concentrically arranged along the same straight line.

[0013] In one embodiment, a connecting hole is provided between the two mounting holes, the connecting hole communicating with the slot, and a limiting mechanism is installed in the connecting hole. The two ends of the limiting mechanism extend into the two mounting holes respectively, and at least a portion of the limiting mechanism is located in the slot. When an external electrical component is inserted into the slot, the limiting mechanism can extend from the connecting hole into the corresponding mounting hole and abut against and limit the locking member.

[0014] In one embodiment, the limiting mechanism includes:

[0015] Two limiting rods are spaced apart within the communicating hole, and each limiting rod can extend into or out of its corresponding mounting hole from the limiting member; and,

[0016] A spring, with two limiting rods connected to its two ends respectively, and a portion of the spring extending into the slot;

[0017] When the external electrical component is inserted into the slot, the spring can push the limiting rods at both ends to extend into the corresponding mounting hole along the connecting hole and abut against the corresponding locking member.

[0018] In one embodiment, the limiting mechanism further includes a return spring, which is installed in the communicating hole, and the two ends of the return spring are respectively connected to the spring plate and the inner wall of the communicating hole.

[0019] In one embodiment, the contact surface is provided with arc-shaped metal sheets that correspond one-to-one with the number of pins and are electrically conductive. All the arc-shaped metal sheets are spaced apart from each other and insulated from each other. The curvature of the arc-shaped metal sheets is consistent with the curvature of the contact surface.

[0020] In one embodiment, both ends of each of the arc-shaped metal sheets extend out of the contact surface.

[0024] The technical solution of this utility model, by setting a terminal body and two self-locking mechanisms, allows the terminal body to have a slot with one open end. The end of the terminal body opposite the open end is arc-shaped and forms a contact surface. A rotating shaft is set on each side wall of the terminal body near the contact surface. Mounting holes are formed on the side walls where the two rotating shafts are located, spaced apart from the rotating shafts and extending into the terminal body. The terminal body can be rotatably connected to an external electrical device through the rotating shafts, and the contact surface can be electrically connected to the external electrical device.

The self-locking mechanism can extend or retract along the mounting hole, so that the utility model can rotate on the external electrical device through the rotating shaft of the terminal body during use. When the terminal body stops rotating, the self-locking mechanism locks the terminal body and the external electrical device. By rotating the terminal body, the communication line connector will not be squeezed due to the confined space when the switch or other electrical equipment is placed in a corner or other relatively small space, thus improving the service life of the connector.

[0037] This utility model proposes a terminal adapter structure and a switch.

[0038] Please see Figures 1 to 5In one embodiment of this utility model, the end adapter structure includes an end body 100 and two self-locking mechanisms 200. The end body 100 has a slot 110 with an opening at one end. The end of the end body 100 facing away from the opening is arc-shaped and forms a contact surface. A rotating shaft 120 is provided on each of the two side walls of the end body 100 near the contact surface. The side walls containing the two rotating shafts 120 have spaced-apart sections that extend into the end body 100. The mounting holes 130 allow the end body 100 to be rotatably connected to an external electrical device via a rotating shaft 120, and the contact surface is electrically connected to the external electrical device. Each mounting hole 130 contains a self-locking mechanism 200, which can extend or retract along the mounting hole 130. The end body 100 can rotate on the external electrical device via the rotating shaft 120, and when the end body 100 stops rotating, the self-locking mechanism 200 locks the end body 100 to the external electrical device.

[0039] In one embodiment, the terminal body 100 has a slot 110 open at one end for receiving an electronic connector. One end of the terminal body 100 forms an arcuate contact surface that can effectively connect to an external electrical device. To achieve fixation and rotation, a pivot 120 extends from each of the two side walls of the terminal body 100. The pivot 120 allows the terminal to rotate on the external electrical device to facilitate electrical connections at different angles.

[0040] A corresponding self-locking mechanism 200 is installed within the mounting hole 130 of the terminal body 100. This self-locking mechanism 200 securely locks the terminal body 100 to the external electrical equipment after the desired angle is reached, ensuring connection stability. In confined spaces, compression of the wiring can cause unstable connector positions; this self-locking mechanism is designed to provide a locked connection after a specific rotation, preventing loosening caused by external forces.

[0041] Of course, in the exemplary embodiment, the self-locking mechanism 200 can achieve automatic locking through an elastic element. When the end reaches the predetermined position, the elastic element causes the self-locking mechanism 200 to extend out of the mounting hole 130 and securely engage with the external device. This self-locking mechanism improves the overall stability and reliability of the device by reducing the probability of loosening of the connecting components in a confined space.

[0042] With the end adapter structure 10, a more robust connection can be achieved when connecting communication lines, even in environments with limited space or complex wiring, thereby increasing the lifespan of the end and reducing the risk of damage caused by compression.

[0043] Of course, to better implement this utility model, in specific implementations, when the example end-cap adapter structure 10 is connected to an external electrical component (such as a switch), the rotation angle of the example end-cap adapter structure 10 can be controlled to rotate and adjust the included angle of the thickness direction intersecting the thickness direction of the switch. It can be clearly stated that in the example end-cap adapter structure 10 of this utility model, its rotation adjustment angle can be based on the centerline of the thickness direction of the switch as the rotation axis. During this process, the rotation angle of the end-cap adapter structure 10 can rotate relative to this rotation axis between -60° and 60°.

[0044] In this embodiment, by providing an end body 100 and two self-locking mechanisms 200, during use, a slot 110 with an opening at one end is formed on the end body 100. The end of the end body 100 away from the opening is arc-shaped and forms a contact surface. A rotating shaft 120 is provided on each of the two side walls of the end body 100 near the contact surface. Mounting holes 130 are formed on the side walls where the two rotating shafts 120 are located, spaced apart from the rotating shafts 120 and extending into the end body 100. The end body 100 can be rotatably connected to an external electrical device through the rotating shafts 120, and the contact surface can conduct electricity with the external electrical device. Each mounting hole 130 contains a self-locking mechanism 200. The self-locking mechanism 200 can extend or retract along the mounting hole 130, allowing the device to rotate on the external electrical equipment via the shaft 120 of the terminal body 100 during use. When the terminal body 100 stops rotating, the self-locking mechanism 200 locks the terminal body 100 to the external electrical equipment. By rotating the terminal body 100, the communication line connectors are not squeezed due to the limited space when electrical equipment such as switches is placed in corners or other confined areas, thus improving the service life of the connectors.

[0045] In one embodiment, please refer to Figure 2 , Figure 3 The self-locking mechanism 200 includes a reset member 210 and a locking member 220. The reset member 210 is installed in the mounting hole 130, and the locking member 220 is connected to the reset member 210. The reset member 210 can drive the locking member 220 to extend or retract from the mounting hole 130.

[0046] Specifically, in the end adapter structure 10, the mounting hole 130 on the end body 100 is used to accommodate the self-locking mechanism 200. The self-locking mechanism 200 consists of a reset member 210 and a locking member 220. The reset member 210 is installed inside the mounting hole 130, while the locking member 220 is directly connected to the reset member 210, thereby enabling the reset member 210 to control the position of the locking member 220 and drive the locking member 220 to extend or retract within the mounting hole 130. When the end body 100 is connected to an external electrical device via the rotating shaft 120 and rotates to a specific position, the reset member 210 drives the locking member 220 to extend out of the mounting hole 130, forming a locking engagement with the corresponding structure of the external electrical device. When it is necessary to adjust the direction of the end body 100, the reset member 210 can be operated to change its state, thereby driving the locking member 220 to retract into the mounting hole 130, releasing the locking state with the external electrical device, and realizing the rotational adjustment of the end body 100.

[0047] In practical implementation, when the terminal body 100 is placed in a corner or other area of ​​a confined space, multiple communication lines will experience compression due to limited space. Traditional fixed connection methods are prone to loosening and breakage under such pressure, reducing service life. However, the self-locking mechanism 200 in this embodiment, through the coordinated action of the reset member 210 and the locking member 220, can maintain a stable locked state when the terminal body 100 is subjected to external force. The reset member 210 can provide a continuous force, ensuring that the locking member 220 always remains extended and locked to the external electrical equipment, and is not easily loosened even under external pressure. This effectively solves the technical problem of reduced service life caused by compression of the connector in a confined space environment.

[0048] Furthermore, the reset element 210 can be constructed using elastic elements, such as springs or sheet elements, which provide a continuous pushing or pulling force to the locking element 220 through their own elastic properties, keeping the locking element 220 in the extended or retracted state. When the end body 100 rotates to the predetermined position, the reset element 210 automatically drives the locking element 220 to extend out of the mounting hole 130 and engage with the locking groove or other corresponding structure on the external electrical equipment to achieve the purpose of locking.

[0049] The key feature of the self-locking mechanism 200 exemplified in this embodiment is its strong adaptability and ease of operation. When the end body 100 needs angle adjustment, the locking member 220 can be easily retracted into the mounting hole 130 by overcoming the force of the reset member 210, thus unlocking the locking state. After adjustment, releasing the operating force will automatically drive the locking member 220 to extend out of the mounting hole 130 and relock. The locking and unlocking method exemplified in this embodiment allows for easy adjustment of the connection angle even in environments with limited space and complex wiring, while ensuring the stability and reliability of the connection, effectively extending the service life of the end adapter structure 10.

[0050] In one embodiment, please continue to refer to Figure 3 The mounting hole 130 includes an interconnected mounting section and a limiting section. The reset member 210 is mounted on the mounting section. The limiting section is gradually narrowed in the direction away from the mounting section. The locking member 220 is a steel ball, which is movably mounted on the limiting section.

[0051] Specifically, during the connection and rotation of the end body 100 with the external electrical equipment, the mounting section of the mounting hole 130 provides space for fixing the reset member 210. The reset member 210 can maintain the dynamic movement state of the locking member 220 (e.g., a steel ball), that is, when the reset member 210 is compressed or released by an external force, it can drive the steel ball located in the limiting section to switch between two states of extension or retraction. The limiting section constrains the range of motion of the steel ball through its tapering structure, preventing the steel ball from sliding out of the mounting hole 130. Since the limiting section gradually narrows from the mounting section, its own tapering structure can restrict the directionality of the moving steel ball, ensuring that the steel ball moves in a specified direction, thereby achieving a stable locking or releasing effect.

[0052] The reset element 210 is installed inside the mounting section, forming a coordinated structure with the moving part of the steel ball located within the limiting section. When the reset element 210 is in its initial state, it applies a pushing force towards the limiting section, causing the steel ball to be pushed to the farthest end of the limiting section, protruding from the mounting hole 130 and locking itself to the corresponding structure of the external electrical device. When an unlocking force is applied externally, pushing the reset element 210 to the other end of the mounting section, the steel ball gradually retracts into the mounting hole 130 under the constraint of the limiting section, releasing the locked state and allowing the end body 100 to rotate freely relative to the external electrical device.

[0053] In some specific embodiments, the reset member 210 employs a spring structure, providing a continuous elastic force to push the locking member 220, i.e., the steel ball, towards the tapered end of the limiting section. When the steel ball reaches its outermost end through the tapered inner diameter of the limiting section, a portion of the steel ball's volume elastically extends out of the mounting hole 130, engaging with the locking groove on the external electrical device to achieve the locking function. Simultaneously, the tapered design of the limiting section ensures the steel ball remains stable within the limiting range during movement, preventing locking failure due to irregular movement of the steel ball caused by external forces. Furthermore, when the engagement structure between the steel ball and the external electrical device is unlocked, the spring reset member 210 returns to its initial state and prepares for re-locking.

[0054] In this embodiment, the mounting section provides a fixing function for the reset member 210, ensuring that the reset member 210 can achieve repeated driving functions. The limiting section effectively constrains the movement range and direction of the steel ball through a gradually narrowing setting, reducing misalignment or failure that may occur due to multi-degree-of-freedom movement. The steel ball, as the locking member 220, utilizes the advantages of its spherical volume contact surface to make contact with the external electrical equipment, making it more secure and reliable. Moreover, its active state can be smoothly switched with the cooperation of the reset member 210.

[0055] In one embodiment, the two mounting holes 130 are concentrically arranged along the same straight line.

[0056] Specifically, mounting holes 130 are provided on both sides of the end body 100, and the mounting holes 130 are concentrically arranged along the same straight line. The concentric arrangement not only simplifies the structural design and improves the installation accuracy, but also enhances the stability of the rotary connection, so that the self-locking mechanism 200 can effectively avoid locking failure due to misalignment during the connection of the end body with the external device.

[0057] With two concentric mounting holes 130, the movement of the reset member 210 and locking member 220 of the self-locking mechanism 200 within the holes is not affected by lateral offset, reducing the problem of functional instability caused by installation errors. When the end body 100 needs to be rotated or fixed, the uniformly straight hole positions ensure that the reset member 210 and locking member 220 exert balanced forces. Therefore, whether in the locked or released state, the locking member 220 can move precisely on a standardized path, ensuring that the connection between the end body 100 and the external electrical equipment remains stable even in confined spaces or under external forces.

[0058] In one embodiment, please continue to refer to Figure 3A connecting hole 230 is provided between the two mounting holes 130. The connecting hole 230 communicates with the slot 110. A limiting mechanism 300 is also installed in the connecting hole 230. Both ends of the limiting mechanism 300 extend into the two mounting holes 130 respectively, and at least a part of the limiting mechanism 300 is located in the slot 110. When an external electrical component is inserted into the slot 110, the limiting mechanism 300 can extend from the connecting hole 230 into the corresponding mounting hole 130 and abut against the limiting locking member 220.

[0059] Specifically, the end body 100 has a slot 110 for inserting an external electrical component. A connecting hole 230 is connected within the slot 110 for mounting a limiting mechanism 300. The limiting mechanism 300 has a movable structure, with both ends capable of entering the two mounting holes 130 respectively. During use, when an external electrical component is inserted into the slot 110, the limiting mechanism 300 responds to the insertion action, unfolding and extending from the connecting hole 230 into the mounting hole 130, causing the end of the limiting mechanism 300 to contact the locking member 220, thereby precisely limiting the locking member 220.

[0060] During the connection and installation process, the limiting mechanism 300 interacts with the slot 110 through the connecting hole 230. When the external electrical component enters the slot 110, the limiting mechanism 300 automatically extends into the mounting hole 130 to limit the locking member 220, ensuring the effectiveness of the self-locking function and preventing the locking member 220 from loosening due to external force.

[0061] In some specific embodiments, the limiting mechanism 300 can be designed as a structure with elastic compression function, which can produce elastic expansion and contraction when subjected to the insertion force of electrical components.

[0062] The optimized design of the limiting mechanism 300 enables the end body 100 to provide stable connection support in different application scenarios. In particular, when external electrical components are removed, the limiting mechanism 300 can retract into the connecting hole 230 under elastic force, preventing interference with the interior of the mounting hole 130 when inactive. This bidirectional movement not only enhances connection stability but also reduces unnecessary pressure and wear on components, thereby helping to extend the overall service life of the equipment.

[0063] In one embodiment, the limiting mechanism 300 includes a spring 320 and two limiting rods 310. The two limiting rods 310 are spaced apart in the communicating hole 230, and each limiting rod 310 can extend into or out of the corresponding mounting hole 130 from the limiting member. The two ends of the spring 320 are respectively connected to the two limiting rods 310, and a part of the spring 320 extends into the slot 110. When the external electrical component is inserted into the slot 110, the spring 320 can push the limiting rods 310 at both ends to extend into the corresponding mounting hole 130 along the communicating hole 230 and abut against the corresponding locking member 220.

[0064] Specifically, the spring 320 of the limiting mechanism 300 transmits power through its elastic properties. When an external electrical component is connected to the slot 110, the spring 320 can be compressed, causing its two ends to push the limiting rods 310 respectively. Under the action of the spring 320, the two limiting rods 310 enter the mounting hole 130 and restrict the locking member 220.

[0065] In some specific embodiments, the spring 320 can have different elastic moduli. By using springs 320 with different elastic moduli, the limiting rod 310 can be precisely adjusted with different forces and speeds when entering the mounting hole 130. Furthermore, this allows the spring 320 to not only maintain its elastic function under continuous insertion and removal actions, but also to reduce stress fatigue during long-term use, thereby improving the durability and reliability of the entire limiting mechanism 300.

[0066] In one embodiment, the limiting mechanism 300 further includes a return spring 330, which is installed in the communicating hole 230, and the two ends of the return spring 330 are respectively connected to the spring sheet 320 and the inner wall of the communicating hole 230.

[0067] Specifically, one end of the return spring 330 is connected to the spring plate 320, and the other end is fixed to the inner wall of the connecting hole 230. When an external electrical component is inserted into the slot 110, the external force causes the spring plate 320 to deform and push the limiting rod 310, thereby causing the limiting rod 310 to extend into the mounting hole 130 along the connecting hole 230 and abut against the locking member 220. At this time, the return spring 330 is in a compressed state, storing elastic potential energy. After the external electrical component is pulled out of the slot 110, the return spring 330 releases its compressive potential energy, driving the spring plate 320 to return to its initial position, and simultaneously causing the limiting rod 310 to retract into the connecting hole 230. This makes the limiting mechanism 300 reusable and improves the convenience and reliability of the insertion and removal operation of the connecting component.

[0068] In one embodiment, the contact surface is provided with arc-shaped metal sheets 140, which are the same number as the pins and are electrically connected in a one-to-one correspondence. All the arc-shaped metal sheets 140 are spaced apart from each other and insulated from each other. The curvature of the arc-shaped metal sheets 140 is the same as the curvature of the contact surface.

[0069] Specifically, multiple arc-shaped metal pieces 140 are provided on the contact surface of the terminal body 100. The number of arc-shaped metal pieces 140 is equal to the number of pins, and each arc-shaped metal piece 140 corresponds one-to-one with a corresponding pin and is electrically conductive. The multiple arc-shaped metal pieces 140 are distributed at intervals, and are electrically isolated by insulating material or insulating gaps to avoid short circuits between adjacent metal pieces. At the same time, the curvature of each arc-shaped metal piece 140 is consistent with the curvature of the entire contact surface, ensuring that the contact surface can fit tightly when in contact with external electrical components.

[0070] Because the contact surface has an arc-shaped structure, the terminal body 100 can rotate over the electrical components. When the arc-shaped metal plate 140 also adopts the same curvature as the contact surface, the contact area can be maximized, enhancing the reliability of electrical contact. Especially when the terminal body 100 is connected to an external electrical component, the arc-shaped metal plate 140 can achieve a more stable and consistent electrical connection with the pins, reducing contact resistance and improving signal transmission quality.

[0071] In some preferred embodiments, the arc-shaped metal sheet 140 can be made of different materials or with different thicknesses to meet different electrical signal transmission requirements. For example, for high-frequency signal transmission, a material with better conductivity can be used to make the arc-shaped metal sheet 140; for high-current transmission, the thickness or width of the metal sheet can be increased. In addition, the surface of the arc-shaped metal sheet 140 can be gold-plated or otherwise surface-treated to improve its conductivity, oxidation resistance, and durability.

[0072] By setting a gap between adjacent metal sheets and filling them with insulating material, signal interference and crosstalk can be effectively prevented.

[0073] In one embodiment, each of the arc-shaped metal sheets 140 has a contact surface extending from both ends.

[0074] Specifically, the arc-shaped metal sheet 140 is not only mounted on the contact surface, but its two ends also extend beyond the edge of the contact surface. This arrangement allows each arc-shaped metal sheet 140 to form a continuous conductive path, extending from one end of the contact surface to the other. Because both ends of the arc-shaped metal sheet 140 extend beyond the contact surface, the metal sheet can not only make contact with the corresponding position of an external electrical component, but also easily connect with other circuit components inside the end body 100 to form a complete circuit path.

[0075] Furthermore, since the entire end structure has a specific rotation function, both ends of the arc-shaped metal sheet 140 are designed to extend into contact surfaces, which enables the present invention to have a larger rotation angle during use, thereby improving the adaptability of the overall end structure or the electrical components using the end structure.

[0076] Based on the same technical concept, in a second aspect, this utility model also proposes a switch, including a terminal adapter structure 10 and a chassis 20 as described in the first aspect. The chassis 20 is provided with a rotating mounting groove 30. The terminal adapter structure 10 is rotatably mounted in the rotating mounting groove 30, and conductive pins 40 are formed in the mounting groove, which are arranged in a one-to-one correspondence with the number of pins. The contact surface can be electrically connected to the conductive pins 40, and the self-locking mechanism 200 can lock the terminal body 100 to the groove wall of the rotating mounting groove 30.

[0077] Specifically, the chassis 20 serves as the outer shell of the switch, and a rotating mounting slot 30 is provided on it to accommodate and support the end-cap adapter structure 10. The rotating mounting slot 30 has a shape and size suitable for insertion of the end-cap body 100. After the end-cap adapter structure 10 is inserted into the rotating mounting slot 30, the end-cap body 100 can rotate at a certain angle within the rotating mounting slot 30. This rotatable installation method allows the end-cap adapter structure 10 to adjust its angle according to actual needs, flexibly adapting to the communication line connection requirements in different directions.

[0078] Multiple conductive pins 40 are formed within the rotary mounting slot 30. The number of conductive pins 40 corresponds to the number of pins on the terminal adapter structure 10, and they are arranged in a one-to-one manner. When the terminal adapter structure 10 is installed in the rotary mounting slot 30, the contact surface on the terminal body 100 can achieve electrical connection with the conductive pins 40 in the mounting slot. The conductive pins 40 are typically connected to the circuit board inside the switch, thereby forming a complete electrical transmission path from the external communication line to the internal circuitry of the switch.

[0079] Once the end adapter structure 10 is inserted into the rotary mounting slot 30 and rotated to a suitable angle, the self-locking mechanism 200 securely locks the end body 100 onto the wall of the rotary mounting slot 30. This method ensures a stable and reliable electrical connection between the end adapter structure 10 and the conductive pin 40, and also prevents the end adapter structure 10 from accidentally loosening or falling off under external force.

[0080] This utility model's switch, through its rotatable end-cap adapter structure 10, enables flexible adjustment of the communication line connection direction. When the switch is placed in a corner or other confined space, the angles of each end-cap adapter structure 10 can be adjusted according to the actual situation, allowing the communication line to be led out in the most suitable direction, avoiding excessive bending and mutual compression of the cables. Simultaneously, the self-locking mechanism 200 ensures that the end-cap adapter structure 10 can be firmly locked after being adjusted to the appropriate angle, maintaining a long-term stable connection.

[0081] In practical applications, the rotating mounting groove 30 can be configured in different shapes to accommodate different types of end adapter structures 10. For example, in one embodiment, the rotating mounting groove 30 can be cylindrical, allowing the end adapter structure 10 to rotate freely within a certain angle range; in another embodiment, the rotating mounting groove 30 can be provided with multiple predetermined positions, enabling the end adapter structure 10 to be locked in these positions, thereby achieving segmented angle adjustment.

[0082] Furthermore, the electrical connection between the conductive pin 40 and the contact surface can also take different forms. For example, the conductive pin 40 can be a flexible design, so that when the end adapter structure 10 is inserted into the rotating mounting slot 30, the conductive pin 40 can maintain contact with the contact surface under the action of elasticity, overcoming the problem of poor contact caused by manufacturing errors or long-term use.

[0083] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
