Description

Technical Field

[0001] This invention relates to a contact element. Background Technology

[0002] There are two main types of existing plug-in structures: plate-type plug-in structures and circular plug-in structures. Plate-type plug-in structures, such as... Figure 1 and Figure 2 As shown, it includes interlocking plate-type socket contacts 101 and plate-type pin contacts 102. The plate-type socket contact 101 includes two opposing first spring arms 1011. In use, the plate-type pin contact 102 is inserted into the channel formed by the two first spring arms 1011, and the plate-type pin contact 102 contacts both first spring arms 1011, achieving electrical signal connection. A circular plug-in structure is shown below. Figure 3 and Figure 4 As shown, it includes a circular socket contact 103 and a circular pin contact 104 that are interlocked. The circular socket contact 103 includes multiple pairs of oppositely arranged second spring arms 1031. In use, the circular pin contact 104 is inserted into the channel formed by the multiple pairs of second spring arms 1031. The circular pin contact 104 is in contact with each of the second spring arms 1031 to achieve electrical signal connection.

[0003] Ideally, after the pin contacts (including the plate pin contact 102 and the circular pin contact 104) are inserted into the socket contacts (including the plate socket contact 101 and the circular socket contact 103), the pin contacts make good contact with each spring arm, achieving electrical signal connection. However, in actual use, it has been found that the pin contacts and socket contacts must be aligned before insertion, such as... Figure 5 As shown, taking the surface-mount socket contact 101 and surface-mount pin contact 102 as examples, when the surface-mount socket contact 101 and surface-mount pin contact 102 are misaligned, mating them together under these conditions will damage the first spring arm 1011 of the surface-mount socket contact 101 or cause excessive local pressure at the mating interface. It may also cause the other first spring arm 1011 to not make contact with the surface-mount pin contact 102, forming a gap 105, or to have a weak contact. This results in excessive contact resistance between the surface-mount pin contact 102 and the surface-mount socket contact 101, leading to increased temperature during signal transmission and potential burnout. The same problem exists when the circular socket contact 103 and the circular pin contact 104 are mated together. Summary of the Invention

[0004] The purpose of this invention is to provide a contact element to solve the technical problem that the contact element is easily damaged when the pin contact element and the hole contact element are misaligned during insertion.

[0005] To achieve the above objectives, the technical solution for the contact provided by the present invention is: a contact, wherein the end of the contact for interlocking with the adapter contact is defined as the front end, and the contact includes:

[0006] The contact body includes:

[0007] The spring arm is provided in at least one pair. The two spring arms in the same pair are arranged opposite each other and used for relative swinging. The rear ends of each spring arm are fixedly connected to each other for electrical communication.

[0008] Each spring arm has a contact area on its opposite outer side for contacting the adapter contact;

[0009] The contact also includes:

[0010] A force transmission component is disposed between two oppositely arranged spring arms. The force transmission component is used to transmit the force to the opposite spring arm when one of the spring arms is subjected to force and swings inward, so that the two opposite spring arms swing in the same direction. The force transmission component is an elastic component, which is fixed between the two opposite spring arms or elastically pressed between the two spring arms.

[0011] The beneficial effects are as follows: by setting a force transmission component between the two spring arms, when the contact component and the matching contact component are misaligned, if one spring arm is subjected to a larger force, the force transmission component will transfer the force to the other spring arm, so that the two spring arms can swing synchronously, ensuring that both spring arms are in contact with the matching contact component, reducing resistance, preventing excessive temperature rise, and effectively protecting the contact component. The elastic component is set between the two spring arms and can transfer the force through elastic deformation.

[0012] As a further optimization, the elastic element is a bent spring sheet with the opening facing backward. The spring sheet includes a side that is either tightly pressed or fixedly connected to the corresponding two spring arms.

[0013] As a further optimization, the side of the spring is braced and pressed between the two opposing spring arms;

[0014] The contact body includes a mounting arm located at the rear end, and the rear end of the side is snapped onto the mounting arm.

[0015] The beneficial effects are: the side and the mounting arm are snap-fitted together, which makes it easy to process separately and install separately, and makes disassembly and assembly more convenient.

[0016] As a further optimization, the spring arms all extend from back to front and inward at an inward angle. The front end of the spring arm is provided with an inwardly bent end section, and an outwardly convex corner is formed at the front end of the spring arm. This corner position forms the contact area.

[0017] The constricted sections of the two opposing spring arms engage with the front end of the spring piece to limit its movement.

[0018] The beneficial effects are: the end section limits the front end of the spring piece, preventing it from coming out and avoiding accidental detachment of the spring piece during normal insertion.

[0019] As a further optimization, the two relatively arranged projectile arms are defined as the first projectile arm and the second projectile arm;

[0020] The force transmission component is a support arm fixed to or integrally formed on the second elastic arm. The support arm can swing elastically relative to the second elastic arm, and the other end of the support arm abuts against the first elastic arm to transmit force.

[0021] The advantages are that the installation method of the outrigger is relatively simple and convenient.

[0022] As a further optimization, one end of the support arm that abuts against the first spring arm bends and extends toward the second spring arm, and the bend extends out with an arc-shaped pressing surface, which is used to abut against and contact the first spring arm.

[0023] The beneficial effect is that the arc-shaped top pressure surface can prevent scratches on the first spring arm and effectively protect the first spring arm.

[0024] As a further optimization, the spring arms all extend from back to front and inward at an inward angle. The front end of the spring arm is provided with an inwardly bent end section, and an outwardly convex corner is formed at the front end of the spring arm. This corner position forms the contact area.

[0025] The spring arm has a protrusion at the corner position, which is used to make contact with the adapter contact element.

[0026] The beneficial effects are: the corner position is where the mating contact part comes into contact, and the wear is greatest at this point. Adding a protrusion at this point can improve the strength of this area and ensure the mating effect; on the other hand, it can also improve the wear resistance and prevent the spring arm from being worn through.

[0027] As a further optimization, the front end of the protrusion is smoothly connected to the spring arm.

[0028] The beneficial effect is that the smooth transition between the protrusion and the spring arm can guide the adapter contact into the outside of the protrusion. Attached Figure Description

[0068] The present invention will be further described in detail below with reference to the embodiments.

[0069] Specific embodiment 1 of the contact element provided by the present invention:

[0070] like Figures 6 to 11 As shown, the contact 202 in this embodiment is actually a plate-type pin contact, which is used to interlock with the socket-type adapter contact 600. For ease of description, in this embodiment, the end of the contact 202 that interlocks with the adapter contact 600 is defined as the front end. The contact 202 includes a contact body 2021 and an elastic element 2025.

[0071] The structure of the contact body 2021 is as follows Figure 8As shown, the contact body 2021 includes a platform 2022, which has a U-shaped structure and includes a first sidewall 20221 and a second sidewall 20222 arranged opposite to each other. A first elastic arm 20241 and a second elastic arm 20242 are fixed to the front end of the platform 2022. The first elastic arm 20241 is connected to the first sidewall 20221, and the second elastic arm 20242 is connected to the second sidewall 20222. The first elastic arm 20241 and the second elastic arm 20242 are electrically connected through the platform 2022, enabling the transmission of the same signal. The first elastic arm 20241 and the second elastic arm 20242 are arranged opposite to each other and can swing relative to each other. Here, the first elastic arm 20241 and the second elastic arm 20242 are defined as swinging inwards when they swing towards each other and swinging outwards when they swing away from each other. In this embodiment, the contact 202 is formed by integral bending.

[0072] like Figure 8 As shown, the first spring arm 20241 and the second spring arm 20242 are both arranged at an angle, and the front ends of the first spring arm 20241 and the second spring arm 20242 are bent towards each other. A constriction section 2027 is formed at the front end of the first spring arm 20241 and the second spring arm 20242. The two constriction sections 2027 cooperate to form a constriction at the front end of the contact body 2021.

[0073] Because the first elastic arm 20241 and the second elastic arm 20242 extend at an angle and their front ends bend towards each other, a convex corner position is formed at the front ends of the first elastic arm 20241 and the second elastic arm 20242. For example... Figure 8 As shown, a protrusion 2026 is fixed at the corner position. There can be one or more protrusions 2026, and their shape can be circular, rectangular, or polygonal. The main function of the protrusion 2026 is to reinforce the corner position of the first spring arm 20241 and the second spring arm 20242. This is because the corner of the first spring arm 20241 and the second spring arm 20242 is the weakest point, but this position mainly contacts and conducts electricity with the adapter contact 600 during use. Reinforcing and thickening this weak point ensures that it is not easily worn through, thus ensuring the reliability of the connection between the contact 202 and the adapter contact 600.

[0074] To ensure smooth mating of the contact 202 and the adapter contact 600, the edges of the protrusion 2026 (especially the front edge) transition with the first spring arm 20241 and the second spring arm 20242 through rounded corners or chamfers. This allows for a smooth transition between the front end of the protrusion 2026 and the spring arms (including the first spring arm 20241 and the second spring arm 20242). The rounded corners or chamfers act as guides during mating, guiding the clamping arm 601 of the adapter contact 600 to smoothly enter the outside of the first spring arm 20241 and the second spring arm 20242. Figure 7 and Figure 8 It can be seen that both the first spring arm 20241 and the second spring arm 20242 have a forked structure at their front ends, which makes them more prone to deformation under stress, ensuring that the contact 202 and the matching contact 600 can be smoothly inserted.

[0075] The contact element 202 also includes an elastic element 2025, which is located between the first elastic arm 20241 and the second elastic arm 20242. Specifically, as shown in the figure... Figure 6 and Figure 7 As shown, the elastic element 2025 here is a U-shaped spring sheet. The U-shaped elastic element 2025 includes two side edges 2028 and a connecting section 2029 connecting the two side edges 2028. The connecting section 2029 can be bent and elastically deformed. The side edges 2028 respectively press against the first spring arm 20241 and the second spring arm 20242, thereby supporting it between the two spring arms. To install the elastic element 2025, as follows... Figure 7 As shown, slots 2030 are provided at the ends of the two side edges 2028. Mounting arms 2023 are fixed to the rear end of the platform 2022. There are two mounting arms 2023, corresponding one-to-one with the two side edges 2028. The slots 2030 fit snugly onto the mounting arms 2023. Simultaneously, the front end of the elastic element 2025 is limited by the tapered section 2027 to prevent it from dislodging. Of course, in actual manufacturing, the two mounting arms 2023 can be combined into one.

[0076] The adapter contact 600 is actually a socket contact, comprising two opposing clamping arms 601. In use, as... Figure 9 and Figure 10 As shown, contact 202 and adapter contact 600 are inserted into each other, and clamping arm 601 drives the first elastic arm 20241 and the second elastic arm 20242 to swing, assembling them together by elastic support. If contact 202 and adapter contact 600 are aligned, the first elastic arm 20241 and the second elastic arm 20242 swing with the same amplitude after being subjected to normal pressure, causing the two sides 2028 of elastic member 2025 to close. Figure 11 As shown, when the contact 202 and the adapter contact 600 are misaligned, one of the clamping arms 601 first contacts the first elastic arm 20241, applying a positive pressure to the first elastic arm 20241. The first elastic arm 20241 transmits the positive pressure to the elastic element 2025, and the elastic element 2025 transmits the pressure to the second elastic arm 20242, so that the first elastic arm 20241 and the second elastic arm 20242 can twist in the same direction, so that the second elastic arm 20242 can contact the other clamping arm 601 to conduct electricity.

[0077] The following is an application scenario for contact 202 - a connection system. The connection system is used to transmit electrical signals from outside the chassis / rack to the PCB 500 inside the chassis / rack, such as... Figures 12 to 31The diagram shows the structure of the connection system.

[0078] like Figure 12 and Figure 13 As shown, the connection system includes a flange socket 200 and a PCB socket 300. The flange socket 200 is fixed to the panel 400 of the chassis / rack during use, with one end extending into the interior of the chassis / rack. A PCB 500 is fixed inside the chassis / rack, and the PCB socket 300 is fixedly mounted on the PCB 500. The flange socket 200 extends along the Z-direction, and the panel 400 is perpendicular to the Z-direction. The panel 400 has a through hole for one end of the flange socket 200 to pass through.

[0079] like Figures 14 to 19 As shown, the flange socket 200 includes a flange socket housing 201, which, for ease of description, is referred to as... Figures 14 to 17 The description is based on the left-right direction shown. It should be noted that the definition of the left-right direction does not limit the structure of the flange socket 200. The flange socket housing 201 has a flange for mounting on the panel 400. The flange socket housing 201 has a through-passage from left to right, with the left end used for mating with an external plug.

[0080] The flange socket 200 includes two contacts 202, the structure of which will not be described in detail here. The two contacts 202 are arranged sequentially in a left-right direction, and are rotated 180° relative to each other. A conductor is connected to the platform 2022 at the left end of each contact 202. Specifically, as... Figure 17 As shown, a second conductor 205 is fixed below the contact 202 at the left end, and a first conductor 204 is fixed above the contact 202 at the right end. Both the first conductor 204 and the second conductor 205 extend in the left-right direction, and a pin 206 is fixedly installed at the left end by a first screw 207. Figure 17 As shown, pin 206 has a structure that is thinner on the left and thicker on the right.

[0081] The flange socket 200 also includes two first support bodies 203, which are fastened to the outside of the two contacts 202, the first conductor 204, and the second conductor 205. The first support bodies 203 support the contacts 202. The inner sides of the two first support bodies 203 have grooves for the contacts 202 to be inserted. Each first support body 203 has a through opening 2031, with two openings 2031 spaced apart on the left and right sides, and the openings 2031 on the two first support bodies 203 are directly opposite each other. The openings 2031 allow the first spring arm 20241 and the second spring arm 20242 of the contacts 202 to extend into, and the protrusions 2026 of the first spring arm 20241 and the second spring arm 20242 extend to the outside of the first support body 203.

[0082] In this embodiment, as Figure 15 As shown, there are guide ramps 2035 on the Z-direction end and the Y-direction side of the first support body 203. The function of the guide ramps 2035 is to guide the flange socket 200 and the PCB socket 300 to be inserted smoothly.

[0083] In this embodiment, to fix the contact 202 and the first support 203 onto the flange socket housing 201, as follows: Figure 15 As shown, a right-facing stop step 2034 is provided at the left end of the first support body 203, and a corresponding annular step is provided on the inner wall of the flange socket housing 201. During assembly, the two first supports 203 are first fastened to the outside of the two contact pieces 202, and then penetrate the flange socket housing 201 from left to right, so that the stop step 2034 of the first support body 203 and the annular step of the flange socket housing 201 stop and cooperate, and then the pressure sleeve 208 is used for pressing.

[0084] The structure of the pressure sleeve 208 is as follows Figure 18 and Figure 19 As shown, the pressure sleeve 208 has two pin through holes 2081 in the middle, each for a pin 206 to pass through. The pin through holes 2081 are stepped holes, forming a right-facing pressing step 2082. Furthermore, as... Figure 18 As shown, the outer periphery of the pressure sleeve 208 has a stepped structure, forming a left-facing pressure sleeve step 2083. The outer periphery of the pressure sleeve 208 has a protruding key 2084, which is used to prevent rotation when engaging with the flange socket housing 201.

[0085] During assembly, the stop step 2034 on the first support 203 engages with the annular step of the flange socket housing 201. The pressure sleeve 208 is inserted into the flange socket housing 201 from left to right, and then the retaining ring 209 is installed to achieve left and right positioning, thus fixing the first support 203 onto the flange socket housing 201. Simultaneously, the pressing step 2082 presses against the pin 206 to provide left and right positioning for the pin 206 and the contact element 202. Figure 17 As shown, a first limiting step 2032 and a second limiting step 2033 facing left are provided on the first support body 203. The two limiting steps are respectively engaged with the platform 2022 in the two contact members 202 to stop left and right. Through the cooperation of the two limiting steps and the pressure sleeve step 2083, the pin 206 and the two contact members 202 are positioned left and right.

[0086] like Figure 13 As shown, the connection system also includes a second screw 700, which is used to secure the flange socket housing 201 to the panel 400.

[0087] The structure of the PCB socket 300 is as shown in Figure 12 and Figure 20 , Figure 21 , Figure 22 , Figure 23 and Figure 24 . When in use, the PCB socket 300 is fixed on the PCB 500. The PCB socket 300 includes two socket units 301. The two socket units 301 are arranged at intervals and are separately fixed on the PCB 500. The two socket units 301 are located on both sides of the first spring arm 20241 and the second spring arm 20242 of the contact 202 in the flange socket 200. The socket unit 301 includes a second support body 302 and a conductor 303 fixed on the second support body 302. The conductor 303 is used to contact the contact 202 to achieve electrical conduction. Among them, each second support body 302 includes two conductors 303. The two conductors 303 are arranged at intervals in the left-right direction in sequence and are used to contact different contacts 202. The conductors 303 on the two socket units 301 are facing each other and respectively contact the first spring arm 20241 and the second spring arm 20242 of the same contact 202.

[0088] The structure of the conductor 303 is as shown in Figure 22 , Figure 23 and Figure 24 . The conductor 303 is arranged in a "U" shape as a whole and includes a clamping edge 3031 extending vertically. The clamping edge 3031 is used to be inserted into the card slot 3021 of the second support body 302 for fixation. The conductor 303 has a fitting surface 3033. The fitting surface 3033 is used to contact and conduct electricity with the first spring arm 20241 and the second spring arm 20242. There are first guiding angles 3034 on the left and right sides of the fitting surface 3033 respectively. The first guiding angles 3034 are used to guide the conductor 303 to be inserted in the left-right direction with the right end of the flange socket 200. Bent edges 3035 are integrally formed on the upper and lower sides of the fitting surface 3033 respectively. The bent edges 3035 are in contact with the fitting surface 3033 through the second guiding angle 3036. The second guiding angle 3036 guides the conductor 303 to be inserted in the up-down direction with the right end of the flange socket 200. The conductor 303 further includes a pin 3032 at the lower end. The pin 3032 is used to be fixedly inserted or directly welded on the PCB 500.

[0089] The structure of the second support body 302 is as shown in Figure 22 and Figure 23As shown, the second support 302 is an insulator, and a slot 3021 is provided on the second support 302 for the mounting edge 3031 of the conductor 303 to be inserted to achieve fixed installation. In this embodiment, to reduce the weight of the second support 302, the interior of the second support 302 can be a hollow structure. Meanwhile, a reinforcing rib 3022 is provided on the second support 302. The function of the reinforcing rib 3022 is: when the flange socket 200 and the PCB socket 300 are inserted, the conductor 303 is subjected to positive pressure, and the reinforcing rib 3022 serves to fix and strengthen the second support 302. Furthermore, as... Figure 21 As shown, the top of the second support 302 is a flat surface 3023, which facilitates the use of a vacuum suction cup to pick up the PCB socket 300 during automated assembly.

[0090] The assembled structure is as follows Figure 12 As shown, a through channel 501 is provided on the PCB500, and the mating surface 3033 in the conductor 303 corresponds vertically to the through channel 501. The right end of the flange socket 200 also corresponds vertically to the through channel 501.

[0091] In this embodiment, an insertion channel for the flange socket 200 is formed between the two socket units 301. Simultaneously, the elastic deformation of the first spring arm 20241 and the second spring arm 20242 enables the two socket units 301 to clamp the flange socket 200. The flange socket 200 extends a certain length in the left-right direction, and the conductor 303 extends a certain length in the up-down direction.

[0092] In this embodiment, when the connection system is in use, if the PCB 500 floats relative to the panel 400 in the X direction, the contact member 202 can achieve floating connection by its own elastic deformation, ensuring reliable contact; if the PCB 500 floats relative to the panel 400 in the Y direction, the PCB socket 300 and the flange socket 200 can achieve floating contact by the contact length in the Y direction, ensuring reliable contact; if the PCB 500 floats relative to the panel 400 in the Z direction, the PCB socket 300 and the flange socket 200 can achieve floating contact by the contact length in the Z direction, ensuring reliable contact.

[0093] The connection system in this embodiment does not have specific restrictions on the installation order, and can be installed in the following order: Figures 25 to 30 As shown, first install the flange socket 200 on the panel 400, then connect the PCB 500 and PCB socket 300 to the flange socket 200. Specifically, as follows... Figure 25 and Figure 26As shown, the flange socket 200 can be installed facing forward or rotated 180° to be installed in reverse on the panel 400. When the PCB 500 is perpendicular to the panel 400, and the PCB socket 300 is on top and the PCB 500 is on the bottom, as shown... Figure 27 As shown, the PCB socket 300 can be first fixedly installed on the PCB 500, and then inserted upwards or downwards onto the outside of the flange socket 200. When the PCB 500 is perpendicular to the panel 400, and the PCB socket 300 is at the bottom, and the PCB 500 is at the bottom, as shown... Figure 28 As shown, the PCB socket 300 can be first fixedly installed on the PCB 500, and then inserted upwards or downwards onto the outside of the flange socket 200. When the PCB 500 is not perpendicular to the panel 400, as... Figure 29 and Figure 30 As shown, regardless of whether PCB socket 300 or PCB 500 is on top, it can be inserted into the outside of flange socket 200, either upwards or downwards.

[0094] Of course, it can also be used as Figure 31 The installation sequence shown is as follows: first, install PCB500 and PCB socket 300 inside the chassis / rack, and then install flange socket 200, which is inserted into the gap formed by the two socket units 301.

[0095] In this embodiment, the elastic element 2025 is used to transmit force, so that the two opposing elastic arms can twist in the same direction, and the elastic element 2025 forms a force transmission element.

[0096] In this embodiment, a protrusion 2026 is provided at the corner position of the first elastic arm 20241 and the second elastic arm 20242. This corner position is used to contact the adapter contact member to form a contact area.

[0097] It should be noted that in actual products, the platform structure can be changed according to the actual situation, such as a block structure.

[0098] Specific embodiment 2 of the contact element of the present invention:

[0099] like Figure 32As shown, the force transmission component in this embodiment is a support arm 800, which is integrally bent from the front end of the second elastic arm 20242. It can swing relative to the second elastic arm 20242, while the other end of the support arm 800 abuts against the first elastic arm 20241. To prevent the support arm 800 from scratching the first elastic arm 20241, the end of the support arm 800 is bent towards the direction of the second elastic arm 20242, forming an arc-shaped pressing surface 801. The arc-shaped pressing surface 801 is used to press against the first elastic arm 20241. The way the first elastic arm 20241 and the second elastic arm 20242 are fixed to the platform 2022 is the same as in Embodiment 1, and will not be described in detail here.

[0100] In other embodiments, the support arm can be installed on the first spring arm in a separate and fixed manner.

[0101] Specific embodiment 3 of the contact element of the present invention:

[0102] In Example 1, the elastic element is a U-shaped spring sheet. In this example, the shape of the spring sheet can be V-shaped or W-shaped, and the two sides of the spring sheet are supported on two opposing spring arms.

[0103] Specific embodiment 4 of the contact element of the present invention:

[0104] In Example 1, the spring is positioned forward and backward using the slot at the rear end and the constricted section of the spring arm. In this example, the forward and backward positioning of the spring can be achieved using only one of the slot and the constricted section.

[0105] Specific embodiment 5 of the contact element of the present invention:

[0106] In Example 1, the spring is held between the two spring arms. In this example, the two sides of the spring can be directly fixed to the two spring arms.

[0107] Specific embodiment 6 of the contact element of the present invention:

[0108] In Example 1, the elastic element is a spring sheet located between the two spring arms. In this example, the elastic element can be a compression spring, which can be fixed between the two spring arms or elastically pressed between the two spring arms. Specifically, slots can be made on the spring arms to limit the movement of the compression spring.

[0109] Specific embodiment 7 of the contact element of the present invention:

[0110] In Example 1, a protrusion is fixed in the contact area of ​​the spring arm to reinforce the contact area. In this example, the protrusion in the contact area can be removed.

[0111] Specific embodiment 8 of the contact element of the present invention:

[0112] In Example 1, the spring arm extends at an angle and has a bent end. In this example, the spring arm may no longer extend at an angle; in order to make contact with the adapter contact, a protrusion may be provided separately on the outside of the spring arm for contact.

[0113] Specific embodiment 9 of the contact element of the present invention:

[0114] In Example 1, the force transmission component is in contact with the spring arm during initial installation. In this example, there is a certain gap between the force transmission component and the spring arm during initial installation. The force transmission component is oscillatingly mounted on the platform. When one of the spring arms undergoes elastic deformation, the spring arm contacts the force transmission component, driving the force transmission component to oscillate, thereby transmitting the force to the other spring arm. Alternatively, the force transmission component itself has a certain degree of elasticity and can undergo elastic deformation.

[0115] Specific embodiment 10 of the contact element of the present invention:

[0116] In Example 1, there is one pair of spring arms. In this example, there may be two or more pairs of spring arms, and there are force transmission components between the two spring arms in the same pair. Of course, for ease of arrangement, the force transmission components can be staggered in the front-back direction.

[0117] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
