Description

Technical Field

[0001] The present application relates to the technical field of electronic devices, and in particular to a connector assembly and a connector. Background Art

[0002] FFC (Flexible Flat Cable) / FPC (Flexible Printed Circuitboard) connector is a connector used to connect terminals and FFC / FPC cables to ensure the transmission of signals / currents between the terminals and the FFC / FPC cables.

[0003] For traditional FFC / FPC connectors, when in use, the cover of the connector is easily loosened from the main body, causing the FFC / FPC cable to be detached from the FFC / FPC connector, making the reliability of the connector poor; in addition, because the cover is covered on the main body before the FFC / FPC cable is assembled to the connector, the user must first lift the cover, then place the FFC / FPC cable between the cover and the main body, and finally cover the cover to complete the assembly of the FFC / FPC cable. It can be seen that the assembly process of the FFC / FPC cable is time-consuming and labor-intensive, resulting in poor convenience of use of the connector. Summary of the invention

[0004] Based on this, it is necessary to provide a connector assembly and a connector to address the problem that the reliability and ease of use of the connector are both poor.

[0005] A connector, comprising:

[0006] A main body, wherein the main body is provided with a pressing groove, a slot and a locking groove, and the pressing groove is communicated with the slot and the locking groove respectively;

[0007] a cover plate, the cover plate being rotatably connected to the main body, and the cover plate being able to slide relative to the main body when the cover plate is rotated relative to the main body to an angle covering the holding groove; and

[0008] The card platform is arranged on the cover plate, and the card platform is opposite to the locking groove when the cover plate is covered in the holding groove, and the card platform is located in the locking groove and is slidably connected with the main body when the cover plate slides relative to the main body.

[0009] In one of the embodiments, a protrusion is provided on the card platform, so that the card platform has a certain friction force when sliding relative to the main body, so that the card platform is not easy to slide relative to the main body, ensuring that the card platform is reliably locked on the main body.

[0010] In one of the embodiments, a positioning groove connected to the locking groove is provided on the main body, and the protrusion is located in the positioning groove when the cover slides to a predetermined position relative to the main body, so that the protrusion is not easy to slide out of the positioning groove of the main body, thereby allowing the card table to be more reliably locked to the main body.

[0011] In one of the embodiments, a clamping platform is provided on the cover plate, and a fastening groove connected to the holding groove is opened on the main body. When the cover plate slides to the predetermined position relative to the main body, the clamping platform is buckled into the fastening groove, so that the cover plate is not easy to slide off the main body, thereby allowing the clamping platform to be more reliably locked to the main body.

[0012] In one of the embodiments, the main body is further provided with a mounting groove, the cover plate is partially located in the mounting groove and is rotatably connected to the main body, and the cover plate can slide in the mounting groove when it is rotated relative to the main body to cover the holding groove, so that the cover plate can slide relative to the main body, and the card table is located in the locking groove and is slidably connected to the main body when the cover plate slides relative to the main body.

[0013] In one of the embodiments, the installation groove is communicated with the holding groove, so that the cover plate can be better arranged on the main body and the material of the main body can be saved.

[0014] In one of the embodiments, the mounting groove includes a rotating portion and a sliding portion that are connected to each other, and the rotating portion is connected to the holding groove; the cover plate is located in the rotating portion and is rotatably connected to the main body, and the cover plate can slide from the rotating portion to the sliding portion when it is rotated relative to the main body to cover the holding groove, so that the cover plate can slide in the mounting groove when it is rotated relative to the main body to cover the holding groove.

[0015] In one of the embodiments, the cover plate is elastic; the main body is also provided with a rotation groove connected to the rotating part, and the cover plate is partially located in the rotation groove and is rotationally connected to the main body, so that the cover plate can rotate smoothly relative to the main body; when the cover plate needs to slide from the rotating part to the sliding part, the user needs to apply a certain thrust to the cover plate to make the cover plate slide away from the rotation groove, so that the cover plate can rotate relatively smoothly relative to the main body.

[0016] In one of the embodiments, the connector further includes a spring sheet, which is disposed on the main body. Part of the spring sheet is located in the mounting groove to limit the cover plate in the mounting groove, thereby preventing the cover plate from sliding off the main body, ensuring that the cover plate is always disposed on the main body, and improving the reliability of the connector.

[0017] In one of the embodiments, the main body is further provided with a clamping groove connected with the mounting groove, and the spring sheet is clamped into the clamping groove so that the spring sheet is firmly arranged on the main body.

[0019] The connector assembly and the connector described above can be used to insert the terminal into the slot and insert the flat cable into the pressing groove so that the terminal contacts the flat cable. Since the cover plate is not covered on the main body when the connector assembly is assembled, the pressing groove is exposed on the outside of the main body, and the flat cable can be quickly inserted into the pressing groove, which makes the assembly of the connector assembly more convenient and improves the convenience of use of the connector. When the flat cable is inserted into the pressing groove, the cover plate is rotated so that the cover plate is rotated relative to the main body to cover the pressing groove, so that the flat cable is pressed between the cover plate and the main body. When the cover plate is rotated to an angle that covers the pressing groove, the cover plate is pushed, and the cover plate slides relative to the main body. The cover plate drives the card table to slide at the same time. The card table is located in the locking groove and slides with the main body until the card table slides to a predetermined position, so that the cover plate is locked on the main body, so that the flat cable is firmly pressed between the cover plate and the main body, which solves the problem that the cover plate of the traditional connector is easily loosened on the main body, resulting in poor reliability of the connector.

[0040] like Figures 1 to 3 As shown, a connector assembly 10 of an embodiment includes a terminal 100, a flat cable 200 and a connector 300. In one embodiment, the connector 300 includes a main body 310, a cover plate 320 and a clamping table 330. In one embodiment, the main body 310 is provided with a pressing groove 311, a slot 312 and a locking groove 313. Figure 2 , Figure 4 and Figure 5 As shown, the pressing groove 311 is connected with the slot 312 and the locking groove 313 respectively. The terminal part is located in the slot, the cable is located in the pressing groove, and the terminal located in the slot is in contact with the cable, so that the terminal is electrically connected to the cable. In this embodiment, the pressing groove and the slot are respectively opened at opposite positions on the main body, that is, the pressing groove is opened on one side of the main body, and the slot is opened on the other side of the main body. The main body is in the shape of a rectangular parallelepiped. The locking groove and the pressing groove can be opened on the same side of the main body, or on two adjacent sides of the main body. Specifically in this embodiment, the locking groove and the pressing groove are opened on the same side of the main body.

[0041] like Figure 6 and Figure 7As shown, in one embodiment, the cover plate is rotatably connected to the main body, and the cover plate can slide relative to the main body when it is rotated relative to the main body to cover the angle of the pressing groove. In one embodiment, the cover plate 320 includes a cover plate body 321, a first rotating shaft 323 and a second rotating shaft 325, and the first rotating shaft and the second rotating shaft are both connected to the cover plate body. The first rotating shaft and the second rotating shaft are both rotatably connected to the main body, and the first rotating shaft can slide relative to the main body when it is rotated relative to the main body to cover the angle of the pressing groove, and the second rotating shaft can slide relative to the main body when it is rotated relative to the main body to cover the angle of the pressing groove. The cover plate body 321 covers the pressing groove 311. In this embodiment, the cover plate body, the first rotating shaft and the second rotating shaft are integrally formed, so that the structure of the cover plate is more compact. In other embodiments, the cover plate body, the first rotating shaft and the second rotating shaft can also be formed separately and connected together by welding or gluing.

[0042] In one embodiment, the card platform is provided on the cover plate. In this embodiment, the number of the card platforms is two, and the two card platforms are provided on both sides of the cover plate body. In one embodiment, the card platform is opposite to the locking groove when the cover plate is covered in the pressing groove, and the card platform is located in the locking groove and is slidably connected to the body when the cover plate slides relative to the body. When the cover plate is covered in the pressing groove, it is pressed on the cable, so that the cable is firmly clamped between the body and the cover plate.

[0043] Since the cover plate is not covered on the main body during the assembly of the connector assembly, the pressing groove is exposed on the outside of the main body, and the cable can be quickly inserted into the pressing groove, making the assembly of the connector assembly more convenient and improving the convenience of the connector; when the cable is inserted into the pressing groove, the cover plate is rotated so that the cover plate rotates relative to the main body to cover the pressing groove, so that the cable is pressed between the cover plate and the main body; when the cover plate is rotated to the angle of covering the pressing groove, the cover plate is pushed, and the cover plate slides relative to the main body, and the cover plate drives the card table to slide at the same time. The card table is located in the locking groove and slides with the main body until the card table slides to a predetermined position, so that the cover plate is locked on the main body, so that the cable is firmly pressed between the cover plate and the main body, solving the problem that the cover plate of the traditional connector is easy to loosen from the main body, resulting in poor reliability of the connector. Since the cover plate is a lift-up structure, the operation process is reduced during the assembly of the connector assembly, which not only saves time but also saves costs.

[0044] like Figure 8 As shown, in one embodiment, the side of the flat cable 200 is provided with an ear button portion 210, and see Figure 2, and the ear button is located in the pressing groove 311. A convex rib 322 is provided on one side of the cover plate 320 covering the main body, and the convex rib abuts on the main body 310, and the convex rib abuts on the ear button to limit the cable in the pressing groove, better prevent the cable from sliding out of the pressing groove, so that the cable is better clamped between the main body and the cover plate. In this embodiment, the two opposite sides of the cable are provided with ear buttons, so that the cable is T-shaped. Two convex ribs are provided on the cover plate, each convex rib abuts on the main body and abuts on the corresponding ear button, effectively avoiding the hidden danger of the cable loosening and exiting the main body, so as to better limit the cable in the pressing groove.

[0045] like Fig. 9 As shown, in order to better install the terminal in the slot, in one embodiment, a barb structure 110 is provided on the terminal 100, so that the terminal is interference-fitted in the slot, even if the barb structure abuts against the inner wall of the slot, so that the terminal is better installed in the slot. It can be understood that the terminal can be a single-sided barb structure or a double-sided barb structure.

[0046] like Fig. 9 As shown, in order to make the terminal better contact with the cable, in one embodiment, the terminal 100 is provided with a bayonet 120. Fig.10 The flat cable 200 is buckled into the bayonet 120, so that the terminal is better against the flat cable. In one embodiment, a convex contact 122 is provided on the inner wall of the bayonet, and the convex contact is against the flat cable and electrically connected to the flat cable, so that the terminal is better against the flat cable.

[0047] The number of male contacts of a general connector is one, that is, the connector is a single-contact connector, which can only contact with the flat cable in one direction, and has limited application limitations, resulting in a small application range of the connector. In order to solve the problem of the small application range of the connector, in one embodiment, the number of male contacts is two, that is, the connector is a double-contact connector. In this embodiment, two opposite male contacts are provided on the inner wall of the bayonet, and the flat cable and terminal can be set to contact in a positive direction or a reverse direction according to the use requirements, so that the connector can be more widely used and the applicability of the connector is improved.

[0048] like Figure 7As shown, in order to ensure that the card table is reliably locked on the main body, in one embodiment, the card table 330 is provided with a protrusion 331, so that the card table has a certain friction when sliding relative to the main body, so that the card table is not easy to slide relative to the main body, ensuring that the card table is reliably locked on the main body, and avoiding the shaking of the connector during transportation or use. In this embodiment, the protrusion is a square structure. The protrusion is provided on one side of the card table, so that a certain friction is required for sliding between the card table and the main body. In one embodiment, the protrusion is integrally formed with the card table, so that the structure of the connector is more compact. Specifically, the number of the card table and the protrusion is two, and the two card tables are respectively located on both sides of the sliding cover body, and the two protrusions are respectively provided on the corresponding card tables, so that the card table is more reliably locked on the main body.

[0049] like Figure 2 As shown, in one of the embodiments, a positioning groove 314 connected to the locking groove 313 is provided on the main body 310. The protrusion 331 is located in the positioning groove when the cover slides to a predetermined position relative to the main body, so that the protrusion is not easy to slide out of the positioning groove of the main body, so that the card table is more reliably locked on the main body. In order to make the processing difficulty of the positioning groove lower, in one of the embodiments, the positioning groove extends to the outside of the main body, so that the processing difficulty of the positioning groove is lower, and the manufacturing cost of the connector is reduced. In one of the embodiments, the extension direction of the positioning groove intersects with the extension direction of the locking groove, so that the protrusion is better inserted into the positioning groove. In this embodiment, the extension direction of the positioning groove is perpendicular to the extension direction of the locking groove.

[0050] like Figure 6 As shown, in order to make the clamping platform more reliably locked on the main body, in one embodiment, the cover plate 320 is provided with a clamping platform 324. Figure 2 The main body 310 is provided with a fastening groove 315 connected to the holding groove 311. When the cover slides to the predetermined position relative to the main body, the clamping platform is buckled into the fastening groove, so that the cover is not easy to slide off the main body, so as to prevent the cover from being withdrawn after being locked to the main body, thereby reinforcing and stabilizing the clamping platform, so that the clamping platform is more reliably locked on the main body. In this embodiment, the fastening groove is provided in the middle part of the main body and is connected to the holding groove.

[0051] like Figure 6 As shown, in order to make the clamping platform more reliably buckled into the fastening groove, in one embodiment, a boss portion 3242 is provided on the clamping platform 324. Figure 2 The clamping platform is buckled into the fastening groove 315, and the boss portion abuts against the inner wall of the fastening groove, so that the clamping platform is more reliably buckled into the fastening groove. In one embodiment, the number of the boss portions is multiple, and the multiple boss portions are distributed at intervals, so that the clamping platform is more securely buckled into the fastening groove.

[0052] like Fig.11 As shown, in one embodiment, the main body 310 is further provided with a mounting groove 316, the cover plate 320 is partially located in the mounting groove and is rotatably connected to the main body, and the cover plate can slide in the mounting groove when it is rotated relative to the main body to cover the pressing groove, so that the cover plate can slide relative to the main body, and the card table is located in the locking groove and slidably connected to the main body when the cover plate slides relative to the main body. In this embodiment, the cover plate is U-shaped. The mounting groove is L-shaped. There are two mounting grooves, and the first rotating shaft and the second rotating shaft are respectively rotatably connected to the two mounting grooves, so that the cover plate is rotatably connected to the main body. The first rotating shaft can slide in the corresponding mounting groove when the cover plate body is rotated relative to the main body to cover the pressing groove. The second rotating shaft can also slide in the corresponding mounting groove when the cover plate body is rotated relative to the main body to cover the pressing groove.

[0053] like Fig.11 As shown, in one embodiment, the mounting groove 316 is connected to the holding groove 311, so that the cover plate is better arranged on the main body and the material of the main body is saved. In this embodiment, both mounting grooves are connected to the holding groove, so that the cover plate is more compactly arranged on the main body and the material of the main body is reduced. The mounting groove and the holding groove are both opened on the same surface of the main body. It can be understood that in other embodiments, the mounting groove and the holding groove may not be connected. In one embodiment, the mounting groove and the holding groove are respectively opened on different surfaces of the main body.

[0054] like Fig.11 As shown, in one embodiment, the installation slot 316 includes a rotating portion 3162 and a sliding portion 3164 that are connected to each other, and the rotating portion is connected to the pressing slot. The cover plate is located in the rotating portion and is rotatably connected to the main body, and the cover plate can slide from the rotating portion to the sliding portion when it is rotated relative to the main body to cover the pressing slot, so that the cover plate can slide in the installation slot when it is rotated relative to the main body to cover the pressing slot.

[0055] In this embodiment, the first rotating shaft is located in the corresponding rotating part and is rotatably connected to the main body, and can slide from the corresponding rotating part to the corresponding sliding part when the cover body rotates relative to the main body to cover the pressing groove. Similarly, the second rotating shaft is located in the corresponding rotating part and is rotatably connected to the main body, and can slide from the corresponding rotating part to the corresponding sliding part when the cover body rotates relative to the main body to cover the pressing groove.

[0056] like Fig.11As shown, in one of the embodiments, the cover plate is elastic. The main body 310 is also provided with a rotation groove 317 connected to the rotation part 3162, and the cover plate is partially located in the rotation groove and is rotatably connected to the main body, so that the cover plate rotates smoothly relative to the main body. When the cover plate needs to slide from the rotation part to the sliding part, the user needs to apply a certain thrust to the cover plate, and the cover plate undergoes elastic deformation to make the cover plate slide off the rotation groove, so that the cover plate rotates relatively smoothly relative to the main body. In this embodiment, the cover plate is a plastic part, which makes the cover plate elastic. In one of the embodiments, the main body is a plastic part, which makes the main body lighter and causes less wear on the cover plate during the sliding process relative to the main body.

[0057] like Figure 3 As shown, in one embodiment, the connector 300 further includes a spring sheet 340, which is disposed on the main body 310. Part of the spring sheet is located in the mounting groove to limit the cover plate in the mounting groove 316, to prevent the cover plate from sliding off the main body, that is, to prevent the cover plate from loosening, to ensure that the cover plate is always disposed on the main body, and to improve the reliability of the connector. In this embodiment, the spring sheet is a metal spring sheet.

[0058] like Figure 3 , Fig.11 and Fig.12 As shown, in order to securely set the spring sheet on the main body, in one embodiment, the main body 310 is further provided with a clamping groove 318 connected to the mounting groove 316, and the spring sheet 340 is clamped into the clamping groove, so that the spring sheet is securely set on the main body. In this embodiment, the number of spring sheets is two. The number of mounting grooves and clamping grooves is two, and the two mounting grooves are respectively connected to the two clamping grooves. Each spring sheet is arranged in the corresponding clamping groove to limit the first rotating shaft and the second rotating shaft in the corresponding mounting groove.

[0059] like Figure 3 and Fig.11 As shown, in order to make the spring sheet more firmly arranged on the main body, in one embodiment, the main body 310 is further provided with a locking slot 319 connected to the locking slot 318. Fig.12 The spring piece 340 includes a spring piece body 342 and an elastic protrusion 344 connected to the spring piece body. Figure 2 As shown, the spring body is buckled into the card slot, and the elastic protrusion is located in the locking card slot, so that the spring is more firmly arranged on the main body. In order to avoid the problem of cracking at the connection between the elastic protrusion and the spring body, in one embodiment, as shown in FIG. Fig.12 As shown, a crack-stop groove 344 a is provided at the connection between the elastic protrusion 344 and the spring body 342 to prevent the connection between the elastic protrusion and the spring body from cracking.

[0060] like Figure 3 As shown, in one embodiment, the cover plate 320 is provided with a convex bump 326, and see Figure 1 When the clamping platform 330 slides relative to the main body, the convex bump slides from the first side of the elastic protrusion to the second side of the elastic protrusion, and the convex bump abuts against the second side, so that the convex bump slides over the protruding area of ​​the elastic protrusion, so that the clamping platform is reliably buckled into the fastening groove, and the cover is completely locked on the main body, which plays a role in reinforcement and stability to prevent the hidden danger of the cover automatically withdrawing after being locked on the main body. When the cover is opened for maintenance, the convex bump needs to be slid from the second side of the elastic protrusion to the first side of the elastic protrusion, and the clamping platform slides out of the fastening groove at the same time, and the cover is moved from the sliding part of the installation groove to the rotating part.

[0061] like Figure 2 As shown, in order to reliably connect the spring sheet to the main body, in one embodiment, the spring sheet 340 further includes a bent portion 346, which is connected to the spring sheet body 342. The bent portion is located in the mounting groove 316 and abuts against the inner wall of the main body 310, so that the spring sheet is reliably connected to the main body.

[0062] like Figure 2 As shown, in one embodiment, the spring 340 further includes a welding portion 348 connected to the spring body 342. The welding portion is bent. The main body 310 is also provided with a clamping groove 310b connected to the clamping groove 318. When the spring body is clamped into the clamping groove, the welding portion is located in the clamping groove, and the welding portion is used to be welded on the PCB board, so that the spring is reliably fixed on the PCB board, thereby fixing the connector on the PCB board. Figure 3 As shown, in one embodiment, the welding 101 of the terminal 100 is welded to the PCB board. When the terminal is inserted into the slot of the main body, the welding of the terminal is welded to the PCB board, and the spring is welded to the PCB board at the same time, so that the connector is reliably fixed on the PCB board.

[0063] In this embodiment, the spring body, the elastic protrusion, the bending part and the welding part are integrally formed, so that the structure of the spring is more compact. Specifically, the spring body, the elastic protrusion, the bending part and the welding part are integrally bent and formed. In other embodiments, the spring body, the elastic protrusion, the bending part and the welding part can also be formed separately and connected together by welding or gluing.

[0064] like Figure 3As shown, in order to improve the heat dissipation performance of the connector, in one embodiment, the main body 310 is provided with a ventilation groove 310a, and the ventilation groove and the slot are provided on the same side of the main body. The ventilation groove is used to allow air outside the main body to be introduced to dissipate heat from the main body, thereby improving the heat dissipation performance of the connector. In one embodiment, the ventilation groove is connected to the holding groove, so that the air outside the main body flows into the holding groove through the ventilation groove, or flows into the ventilation groove through the holding groove, thereby improving the heat dissipation performance of the connector.

[0065] In order to better push or pull out or open the cover, in one embodiment, as Figure 2 As shown, a gripping groove 327 is provided on the cover plate 320, and the user can grasp the cover plate through the gripping groove to better push or pull out or open the cover plate, thereby improving the ease of use of the connector.

[0066] When the connector assembly and the connector are used, the terminal can be inserted into the slot, and the cable can be inserted into the pressing groove so that the terminal contacts the cable. Since the cover plate is not covered on the main body when the connector assembly is assembled, the pressing groove is exposed on the outside of the main body, and the cable can be quickly inserted into the pressing groove, which makes the assembly of the connector assembly more convenient and improves the convenience of the connector. When the cable is inserted into the pressing groove, the cover plate is rotated relative to the main body to cover the pressing groove, so that the cable is pressed between the cover plate and the main body. When the cover plate is rotated to the angle of covering the pressing groove, the cover plate is pushed, and the cover plate slides relative to the main body. The cover plate also drives the card table to slide. The card table is located in the locking groove and slides with the main body until the card table slides to a predetermined position, so that the cover plate is locked on the main body, so that the cable is firmly pressed between the cover plate and the main body, which solves the problem that the cover plate of the traditional connector is easily loosened on the main body, resulting in poor reliability of the connector.

[0067] When installing the connector assembly, first install the terminal in the slot and rivet it into a semi-finished product, then install the plastic cover on the plastic body, and finally insert the two springs into the plastic body to assemble the connector assembly. There are two ways to assemble the cable into the locking slot of the body: 1) Fig.13 As shown, align the cable with the locking groove of the main body and insert the cable parallel to the terminal; 2) Fig.14 As shown in FIG. 1 , first insert the flat cable into the locking slot from top to bottom above the locking slot; Fig.15 As shown, then insert the cable forward so that the cable assembly is inserted into the locking slot and in place to contact the terminal. This method of assembling the cable is simple and will not be inserted incorrectly. Fig.16 shown.

[0068] The following is the specific assembly method of the above connector components:

[0069] (1) Insert the terminal into the plastic body. Since the connector terminal has double contacts and a single-sided barbed structure, the terminal is fixed to the plastic body.

[0070] (2) Assemble the cover plate in a standing position to the corresponding position of the plastic body;

[0071] (3) After inserting the cable with ear clips into the pressing groove, press down the cover plate, and buckle the ear clips of the cable in the pressing groove; because the FFC / FPC cable has ear clips, that is, the FFC / FPC cable is provided with ear clips, and the cover plate is provided with a convex rib on one side of the main body, the convex rib abuts against the main body, and the convex rib also abuts against the ear clip, so that the convex rib and the ear clip cooperate to prevent the cable from exiting the pressing groove, so that the cable maintains a good pulling force after the cable is matched with the connector, which can effectively prevent the cable from loosening and exiting.

[0072] (4) Assemble the spring sheets on the left and right sides respectively. The spring sheets on both sides have a bending part to prevent the cover from loosening on the main body.

[0073] (5) The cover is rotated and pressed down. Since a boss is provided on each side of the cover body, each boss cooperates with a corresponding locking groove provided in the plastic body, so that the connector is not easily shaken during transportation or use.

[0074] (6) Push the cover down into place. Since a fastening groove of the shape of a strip is opened in the middle of the plastic body, and a long strip-shaped clamping platform is opened in the middle of the cover, the clamping platform cooperates with the fastening groove to play a role in reinforcement and stability, preventing the cover from being locked into the fastening groove and then withdrawing.

[0075] (7) Push the cover down into place. Since there are convex bumps on both sides of the cover, and the two convex bumps cooperate with the corresponding elastic protrusions, they play a role in reinforcement and stability, preventing the connector assembly from being locked and withdrawn.

[0076] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be noted that, for a person of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
