For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Embodiments of the present invention are described in detail below, 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 below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0046] like Figures 1 to 6 As shown, this embodiment provides a connector with variable impedance, which is used to be connected in series in a control circuit. Different resistance value signals can be provided in different states when connected, so as to avoid sparks caused by sudden changes in resistance value.

[0047] The impedance variable connector includes a support member 100, a fixed conductive component 200 and a movable conductive component 300, wherein the support member 100 is made of an insulating material; the fixed conductive component 200 is fixedly arranged on the support member 100, and the fixed conductive component 200 has a first fixed conductive portion 211, a second fixed conductive portion 2211 and a third fixed conductive portion 2223; the movable conductive component 300 is arranged on the support member 100, and at least a part of the movable conductive component 300 can move between the first fixed conductive portion 211 and the second fixed conductive portion 2211, and can be connected to the first fixed conductive portion 211 or the second fixed conductive portion 2223. 211 is connected and conductive; the movable conductive member 300 is always connected and conductive with the third fixed conductive member 2223 during the process of moving between the first fixed conductive member 211 and the second fixed conductive member 2211; wherein the contact area between the movable conductive member 300 and the first fixed conductive member 211 is the first area, the contact area between the movable conductive member 300 and the second fixed conductive member 2211 is the second area, and the contact area between the movable conductive member 300 and the third fixed conductive member 2223 is the third area, the third area is smaller than the first area, and the third area is smaller than the second area. In some embodiments, the first area and the second area are different.

[0048] It should be noted that the fixed conductive component 200 and the movable conductive member 300 are both made of conductive materials. Exemplarily, the fixed conductive component 200 and the movable conductive member 300 are both made of copper. When in use, the anti-variable connector is connected in series in the control circuit. Specifically, there are two breakpoints on the path of the control circuit, one of which is connected to the movable conductive member 300, and the other is connected to the fixed conductive component 200.

[0049] In this embodiment, there are at least two connection states between the movable conductive member 300 and the fixed conductive component 200. The entire variable impedance connector always remains connected during use. When damage occurs and causes a circuit break, a circuit break signal can be sent to the controller in time, so that the controller can notify the maintenance personnel of the relevant situation as soon as possible to check and maintain as soon as possible to improve the user experience; among them, when the movable conductive member 300 is located between the first fixed conductive part 211 and the second fixed conductive part 2211, since the movable conductive member 300 and the third fixed conductive part 2223 are connected and conductive, and the contact area is small and the impedance is large, it is helpful to reduce power and energy consumption.

[0050] When the first area and the second area are different, there are three connection states between the movable conductive member 300 and the fixed conductive component 200, and three signals can be sent to the controller. When damage occurs and causes a circuit break, a circuit break signal can be sent to the controller in time, and the circuit break signal is different from the above three signals.

[0051] In some embodiments, the fixed conductive component 200 includes a first conductive member 210, a first fixed conductive portion 211 is disposed on the first conductive member 210, and a movable conductive member 300 has a movable body 310 and a first movable conductive portion 321 disposed on the movable body 310, and the movable body 310 is movably disposed on the support member 100; when the movable conductive member 300 abuts against the first conductive member 210, the first movable conductive portion 321 and the first fixed conductive portion 211 abut and conduct. Specifically, the first conductive member 210 is a block-shaped structure, and its top surface forms the first fixed conductive portion 211, and the movable body 310 is a cylindrical structure, and the lower end surface of the movable body 310 partially protrudes downward to form a long strip-shaped conductive arm 320, and the lower end surface of the conductive arm 320 forms the first movable conductive portion 321. This arrangement enables the lower end surface of the conducting arm 320 and the top surface of the first conducting member 210 to be in contact, thereby achieving connection and conduction between the movable conducting member 300 and the first conducting member 210 and also achieving position limiting between the two.

[0052] In some embodiments, the fixed conductive component 200 further includes a second conductive member 220 conductively connected to the first conductive member 210, a third fixed conductive portion 2223 is disposed on the second conductive member 220, and the movable conductive member 300 has a third movable conductive portion 330, and the contact area between the third movable conductive portion 330 and the third fixed conductive portion 2223 is a third area. The second conductive member 220 and the first conductive member 210 are disposed separately, which is convenient for design, processing and assembly. In the process of the movable conductive member 300 approaching or moving away from the first conductive member 210, the third fixed conductive portion 2223 contacts the third movable conductive portion 330 and relatively slides with each other, so that the movable conductive member 300 always maintains connection and conduction with the second conductive member 220 in the process of approaching or moving away from the first conductive member 210.

[0053] In some embodiments, the second conductive member 220 has a second conductive body 221 and a conductive elastic portion 222 disposed on the second conductive body 221. The third fixed conductive portion 2223 is disposed on the conductive elastic portion 222 and is subjected to the elastic force of the conductive elastic portion 222 to maintain a tendency to move close to the third movable conductive portion 330. The provision of the conductive elastic portion 222 allows the third fixed conductive portion 2223 to maintain good contact with the third movable conductive portion 330 even if it is worn.

[0054] Specifically, the conductive elastic part 222 includes an elastic arm 2221 and an elastic seat 2222, one end of the elastic arm 2221 is connected to the second conductive body 221, and the other end is connected to the elastic seat 2222. A boss protruding toward the third movable conductive part 330 is formed by stamping the sheet-shaped elastic seat 2222, and the boss is close to the side wall of the third movable conductive part 330 to form a third fixed conductive part 2223. There are two second conductive bodies 221, and there are two conductive elastic parts 222. The two conductive elastic parts 222 are arranged in parallel and spaced apart between the two second conductive bodies 221. The two second conductive bodies 221 and the two conductive elastic parts 222 form a frame structure, and the movable conductive member 300 moves in the frame structure. Furthermore, the elastic arm 2221 is U-shaped, and two elastic arms 2221 are provided, and the openings of both are upward, the elastic seat 2222 is located between the two elastic arms 2221, and the two ends of the elastic seat 2222 are respectively connected to the two opposite ends of the two elastic arms 2221, and the two opposite ends of the two elastic arms 2221 are respectively connected to the two second conductive bodies 221. Among them, the elastic arm 2221, the elastic seat 2222 and the second conductive body 221 are integrally formed to ensure the stability and reliability of the connection.

[0055] The movable body 310 is a cylindrical structure, the lower end surface of the movable body 310 partially protrudes downward to form a long strip of conducting arm 320, and the outer side wall of the movable body 310 and the conducting arm 320 forms a third movable conducting part 330. The lower end surface of the conducting arm 320 serves as the first movable conducting part 321, and the outer side wall cooperates with the movable body 310 to serve as the third movable conducting part 330, with a compact structure and overall simplification.

[0056] To improve the safety of use, further, the second fixed conductive part 2211 is provided on the second conductive member 220, and the movable conductive member 300 has a second movable conductive part 341; when the movable conductive member 300 is away from the first conductive member 210, the second fixed conductive part 2211 and the second movable conductive part 341 are connected and conductive. This arrangement allows the movable conductive member 300 and the fixed conductive component 200 to always maintain a connected and conductive state, thereby further reducing the probability of sparks between the movable conductive member 300 and the fixed conductive component 200 when they are in different positions.

[0057] The second conductive body 221 is a sheet-like structure, and its bottom surface forms a second fixed conductive part 2211. The movable conductive member 300 includes a movable body 310 of a cylindrical structure, and the lower end surface of the movable body 310 is partially folded outward to form a limiting arm 340. The upper side surface of the limiting arm 340 forms a second movable conductive part 341. When the movable conductive member 300 is away from the first conductive member 210, the limiting arm 340 abuts against the second conductive body 221. The above arrangement enables the second conductive body 221 to play a limiting role and also play a role in conducting with the second movable conductive part 341.

[0058] In this embodiment, the three connection states between the movable conductive member 300 and the fixed conductive component 200 are: when the movable conductive member 300 is away from the first conductive member 210, the second fixed conductive portion 2211 and the second movable conductive portion 341 are connected and conductive, the first movable conductive portion 321 and the first fixed conductive portion 211 are not connected and not conductive, and the third fixed conductive portion 2223 and the third movable conductive portion 330 are connected and conductive; when the movable conductive member 300 is close to the first conductive member 210, the first movable conductive portion 321 and the first fixed conductive portion 211 are not connected and not conductive, and the third fixed conductive portion 2223 and the third movable conductive portion 330 are connected and conductive. The fixed conductive part 211 is not connected and not conductive, the second fixed conductive part 2211 and the second movable conductive part 341 are not connected and not conductive, and the third fixed conductive part 2223 and the third movable conductive part 330 are connected and conductive; when the movable conductive member 300 abuts against the first conductive member 210, the first movable conductive part 321 and the first fixed conductive part 211 are connected and conductive, the second fixed conductive part 2211 and the second movable conductive part 341 are not connected and not conductive, and the third fixed conductive part 2223 and the third movable conductive part 330 are connected and conductive. In other words, in the three connection states between the movable conductive member 300 and the fixed conductive component 200, the third fixed conductive part 2223 and the third movable conductive part 330 are always connected and conductive.

[0059] To ensure the stability of the connection and conduction between the second conductive member 220 and the first conductive member 210, in some embodiments, the second conductive member 220 includes a second conductive body 221 and a conductive connecting piece 223 disposed on the second conductive body 221; the first conductive member 210 is a block structure, and the top surface of the first conductive member 210 is welded to the conductive connecting piece 223. Further, the second conductive member 220 has at least four conductive connecting pieces 223, and the four conductive connecting pieces 223 are dispersedly disposed on the peripheral side of the second conductive body 221 to improve the force balance.

[0060] The second conductive member 220 is detachably connected to the support member 100. Before welding, the second conductive member 220 and the support member 100 are first connected so that the second conductive member 220 and the first conductive member 210 are relatively fixed to the support member 100, thereby facilitating the connection between the second conductive member 220 and the first conductive member 210 and improving welding efficiency and accuracy.

[0061] In this embodiment, the support member 100 is provided with a slot, and the second conductive member 220 further includes a clamping piece 224 provided on the second conductive body 221, and the clamping piece 224 is clamped in the slot. This arrangement ensures that the position between the second conductive member 220 and the support member 100 remains unchanged during the welding process, which is conducive to ensuring welding accuracy, and the clamping structure is simple, easy to assemble, and improves assembly efficiency.

[0062] The second conductive member 220 has at least two clamping pieces 224 ; the two clamping pieces 224 are respectively located on two sides of the second conductive body 221 to improve the force balance between the second conductive member 220 and the support member 100 .

[0063] The support member 100 is wrapped around the outer circumference of the first conductive member 210 through an injection molding process. The first conductive member 210 is a cylindrical structure, and a stop arm 212 extends circumferentially away from its own axis to prevent the first conductive member 210 from rotating relative to the support member 100.

[0064] In some embodiments, the movable conductive member 300 is subjected to an elastic force so that it is at least partially away from the first fixed conductive portion 211. Exemplarily, the movable conductive member 300 is subjected to an elastic force so that the first movable conductive portion 321 on the movable conductive member 300 is away from the first fixed conductive portion 211. The impedance variable connector includes an elastic member 400, which is disposed between the support member 100 and the movable conductive member 300 and is used to drive the movable conductive member 300 away from the first conductive member 210. The provision of the elastic member 400 makes it easy to adjust the force of the movable conductive member 300 so as to be suitable for different application scenarios. When facing different force requirements, only the elastic member 400 needs to be replaced.

[0065] Regarding the installation position of the elastic member 400, in some embodiments, the support member 100 includes a support seat 110 and a guide ring 120, the movable conductive member 300 includes a movable body 310 of a cylindrical structure and a blocking plate 350 disposed at one end of the movable body 310, the guide ring 120 is located in the movable body 310, the movable conductive member 300 can approach or move away from the support seat 110 along the guide ring 120, and the elastic member 400 is a spring, part of the spring is located in the guide ring 120, and one end of the spring abuts the support seat 110, and the other end abuts the blocking plate 350. Among them, the guide ring 120 can serve as a guide track for the movable conductive member 300, and can also serve as a accommodating structure for the spring to prevent the spring from detaching.

[0066] When in use, the pressing structure presses the blocking plate 350 to push the entire movable conductive member 300 to move closer to the first conductive member 210. In some embodiments, the blocking plate 350 is hemispherical and protrudes in a direction away from the movable body 310. The above structure allows the blocking plate 350 to be balanced when in contact with the pressing structure, and reduces the alignment accuracy between the two, thereby reducing costs.

[0067] In other embodiments, the elastic member 400 may not be provided, and the elastic force is provided by the movable conductive member 300 itself. Specifically, the movable conductive member 300 may include a strip-shaped elastic portion and a docking member, one end of the elastic portion is fixedly connected to the support member 100, and the other end is connected to the docking member, the docking member can move relative to the support member 100, and the first movable conductive portion 321, the second movable conductive portion 341 and the third movable conductive portion 330 are all provided on the docking member.

[0068] In some embodiments, at least two fixed conductive components 200 and at least two movable conductive components 300 are mounted on the support member 100, and the at least two fixed conductive components 200 and the at least two movable conductive components 300 are matched with each other. Exemplarily, three fixed conductive components 200 and three movable conductive components 300 are mounted on the support member 100, and the three fixed conductive components 200 and the three movable conductive components 300 are matched with each other.
