Description

Technical Field:

[0001] The present invention relates to the field of communication technologies, and particularly to a manufacturing process of a TYPE-C data cable. Background Art:

[0002] USB is the abbreviation of Universal Serial BUS in English, and its Chinese abbreviation is "universal serial cable". It is an external bus standard used to standardize the connection and communication between a computer and external devices, and is an interface technology applied in the PC field. USB not only has a fast transmission speed and is very convenient to use. The USB interface also has the advantages of supporting plug-and-play and hot plugging of devices, flexible connection, independent power supply, etc. It can be connected to a mouse, keyboard, printer, scanner, camera, flash drive, mobile phone, digital camera, mobile hard disk, external optical / floppy drive, USB network card, ADSL Modem, Cable Modem, etc. Almost all external devices are equipped with a USB interface and are very widely used.

[0003] Type-C is a connection interface of the USB interface. It can be inserted regardless of the front or back side, and its size is approximately 8.3mm × 2.5mm. Like other interfaces, it supports functions such as USB-standard charging, data transmission, and display output. The TYPE-C connector is mainly for thinner and more slender devices, enhancing usability and paving the way for performance enhancement of future USB versions.

[0004] When manufacturing a Type-C data cable, after peeling off the outermost jacket of the wire and stripping each wire to expose the metal core wire, the metal core wire is directly placed on the solder pad of the PCB board at the rear end of the TYPE-C connector for soldering. This makes the wire soldering operation rather cumbersome. Each time, only one metal core wire can be soldered. Not only does it require identifying the corresponding positions of each metal core wire and each solder pad one by one, making the soldering very inconvenient, but also the soldering work efficiency is extremely low. In addition, the manufacturing / assembly method of the SR head and the housing of the Type-C data cable is as follows: First, the SR head is directly formed by injection molding around the shielding case of the TYPE-C connector, the PCB board, and the end of the wire. Then, the housing is sleeved around the SR head. And the part of the SR head that wraps the end of the wire protrudes outside the housing. Finally, glue is applied between the SR head and the housing to fix the housing and the SR head. This manufacturing / assembly method has the following deficiencies: 1. The manufacturing / assembly steps are numerous, increasing the production cost; 2. Using glue to fix the SR head and the housing, due to the amount of the bonding glue being unable to be guaranteed, the firmness between the two is limited. Especially after long-term use, the SR head and the housing are extremely likely to become detached, affecting the product quality and service life; 3. Since it is difficult to determine the amount of glue applied, it is extremely likely to cause glue overflow. If glue overflow occurs, the overflowed glue needs to be cleaned, increasing the process and reducing the work efficiency.

[0005] In view of this, the present inventor proposes the following technical solutions. Summary of the Invention:

[0006] The object of the present invention is to overcome the deficiencies of the prior art and provide a manufacturing process for a TYPE-C data cable.

[0007] To solve the above technical problems, the present invention adopts the following technical solutions: The manufacturing process of the TYPE-C data cable includes the following steps: S001: Weld and fix the pins of the TYPE-C connector on the pads on the PCB board to form a TYPE-C connector module for later use; S002: Cut a section of wire to a fixed length, manufacture a plastic outer shell, and sleeved the plastic outer shell around the wire; S003: Strip the outer covering of the wire end to expose multiple wires, perform wire separation processing on the wires, then form a wire arrangement positioning glue by low-pressure injection molding to position the wires, then strip the wires to expose the metal core wires, and finally butt and weld the metal core wires to the solder joints on the PCB board for conduction; S004: Form a protective glue core around the PCB board, and the protective glue core also wraps the wires and their metal core wires; S005: Assemble a shielding case, and the shielding case includes a protective glue core, a wire arrangement positioning glue, and the rear end of the TYPE-C connector; S006: Form a hard glue block at the end of the wire, and the hard glue block also wraps the rear end of the shielding case; S007: Push the plastic outer shell relative to the wire, so that the plastic outer shell successively covers the hard glue block, the shielding case, and the rear end of the TYPE-C connector to form a semi-finished product. Among them, multiple ribs in the plastic outer shell are tensioned and positioned with the hard glue block, so that a first gap is formed between the plastic outer shell and the hard glue block, the shielding case, and the rear end of the TYPE-C connector, and a second gap is formed between the hole position of the plastic outer shell and the wire. Then place the semi-finished product in a co-injection mold, and inject soft glue liquid through the second gap into the inside of the plastic outer shell for co-injection molding to form a soft glue colloid, and the soft glue colloid fixes the plastic outer shell, the hard glue block, the shielding case, and the rear end of the TYPE-C connector into one body; the rear end of the soft glue colloid passes through the second gap between the plastic outer shell and the periphery of the wire and extends outside the rear end of the shielding case to form an SR head, and the SR head is integrally fixed with the plastic outer shell and the wire.

[0008] Furthermore, in the above technical solution, in step S002, after the wire is cut off, the middle part of the wire is folded several times and placed in a PE bag, and only the end of the wire extends out of the PE bag.

[0009] Furthermore, in the above technical solution, in step S003, after the wire separation processing of the wires is completed, place the wires in the cavities in the low-pressure molding mold for positioning the wire positions, and inject phenolic resin into the cavities to form the wire arrangement positioning glue. The front ends of all the wires extend out of the front end face of the wire arrangement positioning glue in two upper and lower rows, and the positions correspond to the solder joints on the PCB board.

[0010] Furthermore, in the above technical solution, in step S004, UV glue is applied around the PCB board. The UV glue wraps the electronic components, wires and their metal core wires on the PCB board, and forms the protective glue core through UV light curing.

[0011] Furthermore, in the above technical solution, in step S005, the shielding case includes a left iron shell and a right iron shell that are clamped and fixed around the protective glue core, the wire arrangement positioning glue and the rear end periphery of the TYPE-C connector and are snap-connected. The left wrapping piece at the rear end of the left iron shell and the right wrapping piece at the rear end of the right iron shell clamp and fix the end of the wire. The contact parts between the front ends of the left iron shell and the right iron shell and the metal shell of the TYPE-C connector are fixed by laser welding.

[0012] Furthermore, in the above technical solution, in step S006, the hard glue block is integrally fixed to the end of the wire by injection molding with a hard plastic material. The hard glue block also wraps the left wrapping piece and the right wrapping piece.

[0013] Furthermore, in the above technical solution, in step S007, the insert molding die includes an upper die and a lower die that can be closed and opened relative to each other. The upper end surface of the lower die has a first carrier groove, a first positioning groove, a second positioning groove, a first cavity, and a third positioning groove that are sequentially connected. The lower end surface of the upper die has a second carrier groove, a fourth positioning groove, a fifth positioning groove, a second cavity, and a sixth positioning groove that are sequentially connected and are respectively docked with the first carrier groove, the first positioning groove, the second positioning groove, the first cavity, and the third positioning groove one by one. The upper die is provided with a water inlet that penetrates the upper and lower end surfaces and a runner that connects the water inlet and the second cavity. The first positioning groove and the fourth positioning groove cooperate to wrap and position the TYPE-C connector. The first carrier groove and the second carrier groove are loaded with a plugging member. The end of the plugging member is formed with a tongue plate that penetrates into the mating socket of the TYPE-C connector and blocks the rear side of the first positioning groove and the fourth positioning groove. The second positioning groove and the fifth positioning groove cooperate to wrap and position the plastic shell. The third positioning groove and the sixth positioning groove cooperate to wrap and position the wire and block the rear sides of the first cavity and the second cavity. The first cavity and the second cavity surround the wire periphery and form a third gap with the wire periphery. When soft glue is injected into the water inlet, the soft glue enters and fills the third gap along the runner, then flows into the second gap and then into the first gap, and fills the second gap and the first gap to form the soft glue colloid.

[0014] Furthermore, in the above technical solution, two tapered grooves are formed between the runner and the second cavity. The two tapered grooves are symmetrically distributed at the rear ends on both sides of the second cavity. Spiked overflow grooves are provided on both left and right sides of the first positioning groove. The spiked parts of the overflow grooves communicate with the second positioning groove, so that after the soft glue is injected and fills the first gap, it continues to squeeze into the overflow grooves to ensure that the third gap, the second gap, and the first gap are all filled.

[0015] Furthermore, in the above technical solution, a plurality of exhaust grooves penetrating the outer side surface of the upper mold and the runner are arranged around the runner, and the depth of the exhaust groove is less than or equal to 0.03 mm; a first nylon insert is arranged on the lower mold, and the second positioning groove is arranged on the upper end surface of the first nylon insert; a second nylon insert is arranged on the upper mold, and the fifth positioning groove is arranged on the lower end surface of the second nylon insert.

[0016] Furthermore, in the above technical solution, the first carrier groove and the first positioning groove are arranged on the end surface of a slide bar. A first inclined surface is arranged on the outer side surface of the slide bar, and a pressing block is arranged on the outer side of the lower mold. The pressing block contacts the first inclined surface through the second inclined surface at the lower end. When the pressing block is driven to move downward, the slide bar is driven to move horizontally through the cooperation of the second inclined surface and the first inclined surface, and then the tongue plate of the plugging member is inserted into the mating socket of the TYPE-C connector.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0018] 1. Since the present invention performs wire splitting on the conductors of the wire, and then low-pressure injection molding is used to form a wire arrangement positioning glue to position the conductors, so that the positions of the conductors correspond to the solder joints of the PCB board. When welding the conductors and the solder joints of the PCB board later, it can ensure that all the conductor metal cores are in one-to-one correspondence with the solder joints of the PCB board and are welded and conducted at one time. The welding is very convenient and the welding work efficiency is extremely high.

[0019] 2. After the plastic shell is successively sleeved with the hard rubber block, the shielding shell and the rear end of the TYPE-C connector to form a semi-finished product, the semi-finished product is placed in the insert molding die, and then the insert molding die is used to form a soft rubber colloid inside the plastic shell. The rear end of the soft rubber colloid extends out of the plastic shell and wraps the wire to form an SR head. The production / assembly steps of the soft rubber colloid are few, which can improve production efficiency and reduce production costs. Moreover, the soft rubber colloid can ensure that the plastic shell, the hard rubber block, the shielding shell and the rear end of the TYPE-C connector are fixed together, and the structure is extremely stable and firm, so that the plastic shell is not easy to separate from the soft rubber colloid / TYPE-C connector, ensuring the product quality and service life. And there is no need to perform glue dotting treatment on the SR head and the plastic shell, so there will be no glue overflow phenomenon, ensuring the aesthetic appearance of the product, and thus having extremely strong market competitiveness.

[0030] The present invention will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0031] See Figures 1-10 As shown, it is a manufacturing process of a TYPE-C data cable, and the manufacturing process includes the following steps:

[0032] S001: Weld and fix the pins of the TYPE-C connector 1 on the pads on the PCB board 11 to form a TYPE-C connector module for later use;

[0033] S002: Cut a section of wire 3 to a fixed length, manufacture a plastic outer shell 4, and sleeved the plastic outer shell 4 around the wire 3.

[0034] S003: Strip the outer covering of the end of the wire 3 to expose multiple wires 31, perform wire splitting on the wires 31, then form a wire arrangement positioning glue 5 by low-pressure injection molding to position the wires 31, then strip the wires 31 to expose the metal core wires 311, and finally butt and weld the metal core wires 311 to the solder joints on the PCB board 11 for conduction;

[0035] S004: Mold a protective glue core 6 around the PCB board 11, and the protective glue core 6 also wraps the wires 31 and their metal core wires 311;

[0036] S005: Assemble the shielding case 7, which includes a protective rubber core 6, a flexible cable positioning rubber 5, and the rear end of the TYPE-C connector 1;

[0037] S006: Mold a hard rubber block 8 at the end of the wire 3, and the hard rubber block 8 also wraps the rear end of the shielding case 7;

[0038] S007: Push the plastic housing 4 relative to the wire 3 so that the plastic housing 4 sequentially sheathes the hard rubber block 8, the shielding case 7, and the rear end of the TYPE-C connector 1 to form a semi-finished product. Among them, multiple ribs 41 in the plastic housing 4 are tensioned and positioned with the hard rubber block 8, so that a first gap is formed between the plastic housing 4, the hard rubber block 8, the shielding case 7, and the rear end of the TYPE-C connector 1, and a second gap is formed between the hole 42 of the plastic housing 4 and the wire 3. Then, place the semi-finished product in the insert molding die 9, and inject the soft rubber liquid through the second gap into the interior of the plastic housing 4 for insert molding to form the soft rubber colloid 2. The soft rubber colloid 2 integrates the plastic housing 4, the hard rubber block 8, the shielding case 7, and the rear end of the TYPE-C connector 1 into one body; the rear end of the soft rubber colloid 2 passes through the second gap between the plastic housing 4 and the periphery of the wire 3 and extends out of the rear end of the plastic housing 4 to form the SR head 21, and the SR head 21 is integrally fixed with the plastic housing 4 and the wire 3, so as to ensure the stability of the assembly structure of the SR head 21, and at the same time ensure that the plastic housing 4 will not be detached from the soft rubber colloid 2 / TYPE-C connector 1, and ensure the quality and service life of the product.

[0039] That is to say, since the present invention performs a wire splitting process on the wire 31 of the wire 3, and then positions the wire 31 by low-pressure injection molding of the wire arrangement positioning glue 5, so that the position of the wire 31 corresponds to the solder joints of the PCB board 11. As a result, when the wire 31 and the solder joints of the PCB board 11 are welded later, it can ensure that all the metal core wires 311 of the wire 31 are in one-to-one correspondence with the solder joints of the PCB board 11 and are welded and conducted at one time. The welding is very convenient and the welding work efficiency is extremely high. After the plastic housing 4 is successively sleeved on the hard rubber block 8, the shielding case 7, and the rear end of the TYPE-C connector 1 to form a semi-finished product, the semi-finished product is placed in the insert molding die 9. Then, the insert molding die 9 forms the soft rubber colloid 2 inside the plastic housing 4. The rear end of the soft rubber colloid 2 extends out of the plastic housing 4 and wraps the wire to form the SR head 21. The manufacturing / assembly steps of the soft rubber colloid 2 are few, which can improve the production efficiency and reduce the production cost. Moreover, the soft rubber colloid 2 can ensure that the plastic housing 4, the hard rubber block 8, the shielding case 7, and the rear end of the TYPE-C connector 1 are fixed as a whole, and the structure is extremely stable and firm, so that the plastic housing 4 is not likely to be separated from the soft rubber colloid 2 / TYPE-C connector 1, ensuring the quality and service life of the product. And there is no need to perform glue dotting treatment on the SR head 21 and the plastic housing 4, so there will be no glue overflow phenomenon, ensuring the aesthetic appearance of the product, and thus having extremely strong market competitiveness.

[0040] In addition, the present invention can form four soft rubber colloids at one time to make four finished products.

[0041] In step S002, the plastic housing 4 is a hard plastic shell. Specifically, the plastic housing 4 is integrally formed of PC material, and the inner wall of the plastic housing 4 has a plurality of ribs protruding toward the center position of the inner cavity. The plastic housing 4 is sleeved on the periphery of the wire 3 through its hole 42. Among them, the plastic housing 4 can slide on the periphery of the wire 3 through its hole 42. The hole 42 is a round hole, and the diameter of the round hole is slightly larger than the outer diameter of the wire 3, so that the plastic housing 4 can slide on the periphery of the wire 3, and a second gap is formed between the hole 42 of the plastic housing 4 and the periphery of the wire 3. In addition, after the wire 3 is cut, the middle part of the wire 3 is wound several times and placed in a PE bag, and only the end of the wire 3 extends out of the PE bag, so as to effectively shorten the length of the wire 3 and avoid affecting the progress of the entire manufacturing process due to the too long length of the wire 3.

[0042] In step S003, after the wire 31 is branched and before the solder joints of the metal core wire 311 and the PCB board 11 are welded, the wire 31 is first placed in the cavity of the low-pressure molding die for positioning the wire, and the wire 31 is positioned by the low-pressure molding die. Then, phenolic resin is injected into the cavity to form the wire arrangement positioning glue 5, and the wire arrangement positioning glue 5 positions all the sorted wires 31, so that the front ends of all the wires 31 extend out of the front end face of the wire arrangement positioning glue 5 in two upper and lower rows, and the positions correspond to the solder joints of the PCB board 11. As a result, after the PCB board 11 is inserted between the two upper and lower rows of wires 31, the two upper and lower rows of wires 31 directly rest on the upper and lower end faces of the PCB board 11, and the solder joints of the metal core wire 311 and the PCB board 11 are butted for convenient welding and fixing. The whole process is easy to operate, very convenient for welding, and has extremely high welding efficiency.

[0043] In step S004, UV glue is applied at the periphery of the PCB board 11. The UV glue wraps the electronic components, the wire 31 and its metal core wire 311 on the PCB board 11, and is cured by UV light to form the protective glue core 6. The protective glue core 6 plays a role in protecting the electronic components and the welding structure, avoiding affecting the quality of the electronic components when the soft glue colloid is formed later, and also protecting the stability of the welding structure of the wire 31 and its metal core wire 311.

[0044] In step S005, the shielding case 7 includes a left iron shell 71 and a right iron shell 72 that are clamped and fixed around the periphery of the protective glue core 6, the wire arrangement positioning glue 5 and the rear end of the TYPE-C connector 1 from left and right, and the left iron shell 71 and the right iron shell 72 are also snap-fixed to ensure the stability of the assembly structure. The left wrapping piece 711 at the rear end of the left iron shell 71 and the right wrapping piece 721 at the rear end of the right iron shell 72 are clamped and fixed to the end of the wire 3 to ensure a stable assembly between the shielding case 7 and the end of the wire 3. The contact parts between the front ends of the left iron shell 71 and the right iron shell 72 and the metal shell 12 of the TYPE-C connector 1 are fixed by laser welding to ensure the stability of the assembly structure, and enable the shielding case 7 and the metal shell 12 to provide a comprehensive shielding effect on the whole structure, ensuring the quality and speed of data transmission of the TYPE-C data cable of the present invention.

[0045] In step S006, the hard rubber block 8 is integrally fixed to the end of the wire 3 by injection molding with hard plastic material. The hard rubber block 8 also wraps the left wrapping piece 711 and the right wrapping piece 721 to make the left wrapping piece 711 and the right wrapping piece 721 not exposed. The function of the hard rubber block 8 is to position with the plastic shell 4, and ensure the centrality of the plastic shell 4 and prevent it from being easily offset, so that the size of the first gap formed between the plastic shell 4, the hard rubber block 8, the shielding case 7 and the TYPE-C connector 1 does not change, so as to ensure the injection of the soft glue colloid later and ensure the quality of the product.

[0046] In step S007, the beer sleeve mold 9 includes an upper mold 91 and a lower mold 92 that can be closed and opened relative to each other. Among them, the upper end surface of the lower mold 92 has a first carrier groove 921, a first positioning groove 922, a second positioning groove 923, a first cavity 924, and a third positioning groove 925 that are connected in sequence; the lower end surface of the upper mold 91 has a second carrier groove 911, a fourth positioning groove 912, a fifth positioning groove 913, a second cavity 914, and a sixth positioning groove 915 that are connected in sequence and are respectively butted with the first carrier groove 921, the first positioning groove 922, the second positioning groove 923, the first cavity 924, and the third positioning groove 925. The upper mold 91 is provided with a sprue 910 that penetrates the upper and lower end surfaces and a runner 916 that connects the sprue 910 and the second cavity 914; after loading the semi-finished product and closing the upper mold 91 and the lower mold 92, the first positioning groove 922 and the fourth positioning groove 912 cooperate to wrap and position the TYPE-C connector 1, and the first carrier groove 921 and the second carrier groove 911 are loaded with a plugging member 93. The end of the plugging member 93 is formed with a tongue plate that penetrates into the mating socket of the TYPE-C connector 1 and blocks the rear side of the first positioning groove 922 and the fourth positioning groove 912; the second positioning groove 923 and the fifth positioning groove 913 cooperate to wrap and position the plastic housing 4; the third positioning groove 925 and the sixth positioning groove 915 cooperate to wrap and position the wire 3 and block the rear side of the first cavity 924 and the second cavity 914. The first cavity 924 and the second cavity 914 surround the periphery of the wire 3 and form a third gap with the periphery of the wire 3; when soft glue is injected into the sprue 910, the soft glue enters and fills the third gap along the runner 916, then flows into the second gap along the second gap and fills the second gap and the first gap to form the soft glue colloid 2, and after cooling, the mold is opened to obtain the finished product. Among them, after the mold is opened, the finished product will be accompanied by a lot of auxiliary materials 101 formed in the runner and the sprue, and the auxiliary materials 101 can be removed in the later stage, and its operation is extremely simple.

[0047] There are two tapered grooves 917 formed between the runner 916 and the second cavity 914. The two tapered grooves 917 are symmetrically distributed at the rear ends on both sides of the second cavity 914. During the injection of soft glue, since the soft glue enters the second cavity 914 after passing through the runner 916 and the two tapered grooves 917, the tapered grooves 917 can increase the pressure, enabling the soft glue to quickly enter between the second cavity 914 and the first cavity, that is, quickly enter the third gap, ensuring the injection molding quality. On both the left and right sides of the first positioning groove 922, there are overflow grooves 926 in the shape of pointed cones. The pointed parts of the overflow grooves 926 are connected to the second positioning groove 923. After the soft glue is injected and fills the first gap, it continues to squeeze into the overflow grooves 926, ensuring that the third gap, the second gap, and the first gap are all filled, improving the molding quality of the soft glue colloid. A positioning flange 22 is formed on the outer periphery of the front end of the soft glue colloid 2. The positioning flange 22 is filled in the annular positioning groove 43 formed on the inner wall of the front end opening of the plastic shell 4, further ensuring the stability of the assembly of the soft glue colloid 2 and the plastic shell 4.

[0048] A number of exhaust grooves are provided on the periphery of the runner 916, which penetrate the outer side surface of the upper mold 91 and the runner 916. The depth of the exhaust grooves is less than or equal to 0.03 mm. Since the exhaust grooves are extremely shallow, no soft glue will pass through them, and only gas can pass through, so as to achieve the effect of exhausting gas, thereby ensuring the molding quality of the soft glue colloid 2. The lower mold 92 is provided with a first nylon insert 927, and the upper end surface of the first nylon insert 927 is provided with the second positioning groove 923 mentioned above. The upper mold 91 is provided with a second nylon insert 918, and the lower end surface of the second nylon insert 918 is provided with the fifth positioning groove 913. Clamping and positioning the plastic shell 4 with the first nylon insert 927 and the second nylon insert 918 can ensure the aesthetic appearance of the plastic shell 4, preventing the outer surface of the plastic shell 4 from being scratched or scalded.

[0049] The first carrier groove 921 and the first positioning groove 922 are provided on the end surface of a slide bar 94. The outer side surface of the slide bar 94 is provided with a first inclined surface. A pressing block 95 is provided outside the lower mold 92. The pressing block 95 contacts the first inclined surface through the second inclined surface at the lower end. When the pressing block 95 is driven to move downward, the slide bar 94 is driven to move horizontally through the cooperation of the second inclined surface and the first inclined surface, and then the tongue plate of the plugging member 93 is inserted into the mating socket of the TYPE-C connector 1.

[0050] In summary, since the present invention performs wire splitting on the wire 31 of the wire 3, and then positions the wire 31 by low-pressure injection molding of the wire arrangement positioning glue 5, so that the position of the wire 31 corresponds to the solder joints of the PCB board 11. Therefore, when welding the wire 31 to the solder joints of the PCB board 11 later, it can ensure that all the metal core wires 311 of the wire 31 are in one-to-one correspondence with the solder joints of the PCB board 11 and are welded and conducted at one time. The welding is very convenient and the welding work efficiency is extremely high. After the plastic shell 4 is successively sleeved on the hard rubber block 8, the shielding shell 7 and the rear end of the TYPE-C connector 1 to form a semi-finished product, the semi-finished product is placed in the overmolding die 9, and then the overmolding die 9 overmolds the inside of the plastic shell 4 to form the soft rubber colloid 2. The rear end of the soft rubber colloid 2 extends out of the plastic shell 4 and wraps the wire to form the SR head 21. The manufacturing / assembly steps of the soft rubber colloid 2 are few, which can improve the production efficiency and reduce the production cost. Moreover, the soft rubber colloid 2 can ensure that the plastic shell 4, the hard rubber block 8, the shielding shell 7 and the rear end of the TYPE-C connector 1 are fixed as a whole, and the structure is extremely stable and firm, so that the plastic shell 4 is not easy to separate relative to the soft rubber colloid 2 / TYPE-C connector 1, ensuring the quality and service life of the product. And there is no need to perform glue dotting treatment on the SR head 21 and the plastic shell 4, so there will be no glue overflow phenomenon, ensuring the aesthetic appearance of the product, and thus having extremely strong market competitiveness.

[0051] Certainly, the above are only specific embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention shall be included in the scope of the patent application of the present invention.
