Description

Technical Field

[0001] This application belongs to the field of explosion-proof technology, and in particular relates to an antenna, a lighting device, and a method for manufacturing the antenna. Background Technology

[0002] Communication between two components typically uses wired or wireless transmission. Wired transmission has drawbacks such as complex wiring, susceptibility to lightning strikes, and high installation and maintenance costs. Wireless transmission, on the other hand, can perfectly solve these problems. Wireless transmission is usually achieved through an antenna. An antenna is an important component that receives and transmits electromagnetic wave signals. Antennas are suitable for harsh industrial environments where wiring is difficult. Wireless transmission reduces investment in manpower and resources.

[0003] However, the antenna can currently only be used for transmission in non-explosion-proof locations. There are safety hazards in using high-power, high-gain antennas in places with flammable gases. Summary of the Invention

[0010] Optionally, the housing includes a first straight cylindrical portion, a horn portion, and a second straight cylindrical portion. The smaller end of the horn portion communicates with the first straight cylindrical portion, and the larger end of the horn portion communicates with the second straight cylindrical portion. The first straight cylindrical portion and the second straight cylindrical portion are smoothly connected through the horn portion. The emitter is inserted into the first straight cylindrical portion and the horn portion. The second straight cylindrical portion is sleeved on the boss and injection molded to connect with the boss.

[0011] Optionally, the first straight section, the flared section, and the second straight section are integrally injection molded.

[0012] Optionally, the antenna further includes a mounting base for fixing to the external component, the base having a mounting surface parallel to the axis of the housing; the mounting surface is provided with a rotating column, the axis of the rotating column being perpendicular to the mounting surface, the mounting base having a rotating hole, the rotating column being inserted into the rotating hole and being able to rotate within the rotating hole.

[0013] Optionally, the mounting surface is provided with a plug-in protrusion, and the fixing seat is provided with at least two plug-in grooves. The plug-in grooves are arranged in a circular array with the axis of the rotating hole as the center. The plug-in protrusion is inserted into different plug-in grooves so that the housing presents different angles relative to the fixing seat.

[0014] Alternatively, the mounting surface may have at least two insertion grooves, and the fixing base may have insertion protrusions. The insertion grooves may be arranged in a circular array around the axis of the rotating column, and the insertion protrusions may be inserted into different insertion grooves so that the housing presents different angles relative to the fixing base.

[0015] The antenna provided in this application has at least one of the following technical effects: Since the base is cast at the connection between the transmitter and the wire, the base completely covers and seals the connection, resulting in good sealing performance and high structural strength, thus providing excellent explosion-proof performance. Furthermore, the casting method further enhances the antenna's explosion-proof performance. Additionally, the connection between the housing and the base is also achieved through casting, resulting in good sealing performance and high structural strength, further improving the antenna's explosion-proof performance. Therefore, after the above improvements, the antenna in this application has excellent explosion-proof performance, meeting the requirements for use in explosion-proof environments.

[0016] Another technical solution adopted in this application is: a lighting device, including the antenna described above.

[0021] After the housing is fitted onto the transmitter, the housing and the antenna transmitting mechanism are placed and fixed in the second mold. Then, material is poured into the second mold, and after the material has solidified, the housing and the base are connected.

[0022] The antenna manufacturing method of this application involves first placing the designed transmitting component into a first mold, then electrically connecting the conductor to the transmitting component, and then fixing the transmitting component and the conductor into the first mold. Next, material is injected into the first mold, and after the material solidifies, a base is obtained. The base serves to fix the transmitting component and the conductor, as well as to seal the surface; this is a primary molding process. Subsequently, the housing and the antenna transmitting mechanism are placed in a second mold for secondary molding. After placing the housing and the first-molded antenna transmitting mechanism into the second mold, a second casting process is performed to fuse the two together; this is a secondary molding process. Thus, the antenna of the embodiment of this application is obtained. Through two casting processes, an antenna with explosion-proof performance is obtained, achieving an explosion-proof effect.

[0045] In related technologies, antenna 10 is an important component for receiving and transmitting electromagnetic wave signals. In a network, the wireless AP transmits signal power to antenna 10 through an RFID card, and then antenna 10 radiates electromagnetic waves into the air. The terminal also uses antenna 10 in the air to receive electromagnetic wave signals.

[0046] The characteristics of wireless 433MHz band transmission are: 433MHz is a license-free transmission and reception frequency in our country, which can be used directly without management. The 433MHz band has strong anti-interference capabilities and supports various point-to-point and point-to-multipoint wireless data communication methods. It features integrated transmission and reception, secure isolation, installation isolation, ease of use, high cost-effectiveness, and stability and reliability. As long as the transmission power is high enough, there are no problems with long-distance transmission.

[0047] In some harsh industrial environments where cabling is difficult, wireless transmission can reduce investment in manpower and resources. Wired methods have inherent drawbacks, such as complex wiring, susceptibility to lightning strikes, and high installation and maintenance costs. In recent years, the rapid development of wireless communication and low-power embedded technologies has given rise to wireless sensor networks, which have brought about a revolution in information sensing due to their low power consumption, low cost, distributed nature, and self-organizing characteristics. Advantages of wireless transmission networks include: enhanced resistance to lightning strikes; traditional sensor networks rely on cables for data transmission and power supply, while wireless sensor network nodes are battery-powered and transmit data wirelessly; during product installation, only the product nodes need to be fixed in suitable locations, allowing for flexible installation and saving on deployment costs.

[0048] like Figures 1-6 As shown, in one embodiment of this application, an antenna 10 is provided. The antenna 10 is fixed to the product, and the product communicates with a control device through the antenna 10 to achieve product control. The antenna 10 of this application can be used in automobiles, lighting equipment 20, drones, and other devices. The following description uses the example of the antenna 10 being installed on the lighting equipment 20 as an example.

[0049] Combination Figure 1 and Figure 4 As shown, the antenna 10 includes a housing 11 and an antenna transmitting mechanism 12. The antenna transmitting mechanism 12 includes a transmitter 121, a base 122, and a wire 123 for electrical connection with external components. The transmitter 121 is electrically connected to the wire 123 to electrically conduct the signal between the transmitter 121 and the external components. Specifically, one end of the wire 123 is electrically connected to the transmitter 121, and the other end of the wire 123 is electrically connected to the control board inside the lighting device 20, thereby realizing electrical connection between the antenna 10 and the control board inside the lighting device 20. In this way, by acquiring and sending commands through the antenna 10, the switching on and off of the lighting device 20, the brightness adjustment of the lights, etc. can be controlled. The specific adjustment functions are not listed here.

[0050] Furthermore, the base 122 covers the connection between the transmitter 121 and the wire 123, and the base 122 is formed by casting at the connection between the transmitter 121 and the wire 123. Specifically, the electrically connected transmitter 121 and wire 123 are placed together into the first mold, and then plastic is injected into the first mold. The plastic solidifies at the connection between the transmitter 121 and the wire 123 to form the base 122, and the base 122, transmitter 121, and wire 123 are connected as a whole to obtain the antenna transmitting mechanism 12. It should be noted that the first mold has a first injection cavity that matches the shape of the base 122. After the transmitter 121 and wire 123 are fixed in a predetermined position on the first mold, the connection between the transmitter 121 and the wire 123 is located in the first injection cavity. The base 122 is obtained by filling the first injection cavity with plastic.

[0051] The housing 11 is fitted onto the transmitter 121 and cast to connect with the base 122. Specifically, the housing 11 is a hollow cylinder with an opening at one end. The transmitter 121 is inserted into the housing 11 through the opening, and the base 122 is inserted into the opening. After the opening is blocked, the housing 11 and the antenna transmitting mechanism 12 are placed into a second mold. Then, plastic is injected into the second mold, filling the gap between the housing 11 and the base 122 and covering the connection between the housing 11 and the base 122 before curing. This connects the housing 11 and the base 122 into one unit. It should be noted that the second mold has a second injection cavity. After the housing 11 and the base 122 are fixed in a predetermined position on the second mold, the connection between the housing 11 and the base 122 is located in the second injection cavity. The housing 11 and the base 122 can be connected together by filling the second injection cavity with plastic. The cross-sectional dimension of the second injection cavity is larger than the cross-sectional dimension of the housing 11. The second injection cavity can be cylindrical or prismatic, and its specific shape is not limited here.

[0052] The plastic can be PC, ABS, or PC+ABS. Of course, in other embodiments, the plastic can also be other materials, which will not be listed here.

[0053] In this embodiment of the antenna 10, the base 122 is cast at the connection between the transmitter 121 and the wire 123. This allows the base 122 to completely cover and seal the connection between the transmitter 121 and the wire 123, resulting in good sealing performance and high structural strength. This gives the antenna 10 excellent explosion-proof performance. Furthermore, the base 122 is injection molded, further enhancing its structural strength and improving the explosion-proof performance of the antenna 10. Additionally, the housing 11 is also connected to the base 122 via casting, ensuring good sealing and high structural strength at the connection point, which also further improves the explosion-proof performance of the antenna 10. Therefore, after these improvements, the antenna 10 of this application exhibits excellent explosion-proof performance, meeting the requirements for use in explosion-proof environments.

[0054] In actual use, the antenna 10 of this application embodiment can meet different frequency requirements by changing the transmitting element 121 for signals of different frequencies. That is, the antenna 10 of different frequencies can adopt the same structure, and only the transmitting element 121 needs to be replaced.

[0055] In another embodiment of this application, the transmitting element 121 of the antenna 10 includes electronic components (not shown) and a housing (not shown) covering the electronic components. The housing is obtained by casting around the electronic components, and the electronic components are electrically connected to the wires 123. Specifically, the electronic components are placed in a third mold, and then plastic is injected into the third mold. After the plastic covers the electronic components and cures, the housing is obtained. That is, the electronic components are sealed by injection molding, and the housing is tightly attached to the outside of the electronic components, completely isolating the electronic components from the outside world. External air and moisture cannot enter between the electronic components and the housing, giving the transmitting element 121 good explosion-proof performance. In addition, external water cannot come into contact with the electronic components, which also improves the waterproof performance of the transmitting element 121. The housing is obtained by injection molding, and the structural strength of the housing is good, which can further improve the explosion-proof performance. The electronic components can be existing signal receiving and transmitting components in the antenna 10, such as copper tubes. Their specific types and structures will not be described here.

[0056] The third mold has a third injection cavity that is adapted to the shape of the outer shell. After the electronic components are fixed in the predetermined position of the third mold and are located in the third injection cavity, the outer shell can be obtained by filling the third injection cavity with plastic.

[0057] In another embodiment of this application, the conductor 123 of the antenna 10 includes a conductor core (not shown) and a protective layer (not shown) covering the conductor core. The protective layer is obtained by casting around the conductor core, and the conductor core is electrically connected to the transmitter 121. Specifically, the conductor core is fixed in a fourth mold, and then plastic is injected into the fourth mold. After the plastic covers the conductor core, it is cured to obtain the conductor 123. In this way, the protective layer is tightly attached to the outside of the conductor core and completely isolates the conductor core from the outside world. External air and moisture cannot enter between the conductor core and the protective layer, giving the conductor 123 good explosion-proof performance. In addition, external water cannot come into contact with electronic components along the conductor core, which also improves the waterproof performance of the antenna 10. The protective layer is obtained by injection molding, and the conductor 123 has good structural strength, which can further improve the explosion-proof performance. The conductor core is made of copper wire, aluminum wire, etc.

[0058] The fourth mold has a fourth injection cavity that matches the shape of the protective layer. After the guide core is fixed in the predetermined position of the fourth mold and passes through the fourth injection cavity, the protective layer can be obtained by filling the fourth injection cavity with plastic.

[0059] In another embodiment of this application, see [reference] Figure 4 and Figure 5As shown, the base 122 of the antenna 10 has a boss 1221 on its end face near the transmitter 121. The end of the housing 11 is fitted onto the boss 1221 and is injection molded to connect with the boss 1221. The housing 11 is fitted onto the boss 1221, and the boss 1221 blocks the opening of the housing 11, thereby sealing the housing 11. The boss 1221 is inserted into the housing 11 and connected to the housing 11, resulting in good connection reliability. In addition, when plastic is applied to the connection between the housing 11 and the base 122, the plastic also fills the gap between the boss 1221 and the housing 11 and then cures, thus improving the sealing performance of the housing 11 and the explosion-proof performance of the antenna 10.

[0060] In another embodiment of this application, see [reference] Figure 4 and Figure 5 As shown, the housing 11 of the provided antenna 10 includes a first straight cylindrical portion 111, a horn portion 112, and a second straight cylindrical portion 113. The smaller end of the horn portion 112 is connected to the first straight cylindrical portion 111, and the larger end of the horn portion 112 is connected to the second straight cylindrical portion 113. The first straight cylindrical portion 111 and the second straight cylindrical portion 113 are smoothly connected through the horn portion 112. The transmitting element 121 passes through the first straight cylindrical portion 111 and the horn portion 112. The second straight cylindrical portion 113 is sleeved on the boss 1221 and is injection molded to the boss 1221. Specifically, the larger size of the second cylindrical portion 113 results in a larger connection area between the second cylindrical portion 113 and the boss 1221, leading to a greater mass of plastic accumulation between the second cylindrical portion 113 and the boss 1221. This results in better sealing performance of the housing 11, higher connection strength between the housing 11 and the base 122, and better explosion-proof performance. In addition, the smaller cross-sectional size of the launching element 121, with its size matching that of the first cylindrical portion 111, avoids material waste. Furthermore, the smooth transition between the first cylindrical portion 111 and the second cylindrical portion 113 via the horn portion 112 also avoids stress concentration, giving the entire housing 11 better explosion-proof performance.

[0061] In another embodiment of this application, the first cylindrical portion 111, the horn portion 112, and the second cylindrical portion 113 of the antenna 10 are integrally injection molded. Specifically, the housing 11 is obtained by injection molding, and the entire housing 11 is a one-piece structure, which has better structural strength, better explosion-proof performance, and is simpler and more convenient to manufacture.

[0062] In another embodiment of this application, see [reference] Figure 4 and Figure 5As shown, the antenna 10 also includes a mounting base 13 for fixing to an external component. The base 122 has a mounting surface 1222 parallel to the axis of the housing 11. The mounting surface 1222 is provided with a rotating post 1224, the axis of which is perpendicular to the mounting surface 1222. The mounting base 13 has a rotating hole 132, into which the rotating post 1224 is inserted and can rotate. The angle of the antenna 10 can be adjusted by rotating the rotating post 1224 within the rotating hole 132.

[0063] In this embodiment of the application, the antenna 10 further includes a locking member 15, wherein, in conjunction with Figure 4 and Figure 5 As shown, the mounting base 13 is installed on the side of the top cover 21 of the lighting device 20 by screws; the mounting surface 1222 is provided with a plugging protrusion 1223, and the mounting base 13 is provided with at least two plugging grooves 131. The plugging grooves 131 are arranged in a circular array around the axis of the rotating hole 132. The plugging protrusion 1223 is inserted into different plugging grooves 131 so that the base 122 and the mounting base 13 present different angles; or, the mounting surface 1222 is provided with at least two plugging grooves 131, and the plugging grooves 131 are arranged in a circular array around the axis of the rotating hole 132. 31 are arranged in a circular array around the axis of the rotating column 1224; the fixed base 13 is provided with a plugging protrusion 1223, which is inserted into different plugging grooves 131 so that the base 122 and the fixed base 13 present different angles; the locking member 15 has an unlocked state and a locked state; when the locking member 15 is in the locked state, the plugging protrusion 1223 is locked in the plugging groove 131; when the locking member 15 is in the unlocked state, the plugging protrusion 1223 can be moved out of the plugging groove 131.

[0064] Specifically, when the locking member 15 is in the locked state, the insertion protrusion 1223 is inserted into the insertion groove 131. At this time, the fixing seat 13 and the base 122 are relatively fixed. When it is necessary to change the angle of the antenna 10, first turn the locking member 15 to the unlocked state, move the insertion protrusion 1223 out of the insertion groove 131, then rotate the base 122 so that the housing 11 rotates to the preset angle, and then insert the insertion protrusion 1223 into the corresponding insertion groove 131, and then lock the locking member 15. In this way, the angle of the antenna 10 can be adjusted. In addition, through the adaptation of the insertion protrusion 1223 and the insertion groove 131, the base 122 cannot rotate relative to the fixing seat 13, and the antenna 10 is fixed at the preset angle, preventing the antenna 10 from rotating arbitrarily due to external force, and ensuring that the antenna 10 has good communication function.

[0065] In this embodiment, the number of insertion protrusions 1223 can be two, three, four or more, and the insertion protrusions 1223 are also in a circular array. The number of insertion grooves 131 can be two, three, four or more, to ensure that the insertion protrusions 1223 can be inserted into different insertion grooves 131 so that the antenna 10 presents different angles. The specific number can be selected according to the actual situation and is not limited here.

[0066] For example, combined Figure 4 and Figure 5 As shown, there are four insertion protrusions 1223, and the included angle between two adjacent insertion protrusions 1223 is 90°. There are 12 insertion grooves 131, and the included angle between two adjacent insertion grooves 131 is 30°. In this way, by inserting the insertion protrusions 1223 into different insertion grooves 131, the angle of the antenna 10 can be adjusted from -90° to 90°. It should be noted that the angle of the antenna 10 refers to the angle between the axis of the antenna 10 and the horizontal plane when the light-emitting part of the lighting device 20 is set downward.

[0067] In another embodiment of this application, combined with Figure 2 and Figure 3 As shown, the antenna 10 provided also includes an end cap 14, a locking member 15 which is a fastener; a rotating hole 132 is a stepped hole, a rotating post 1224 is inserted into the small section of the stepped hole, the end cap 14 is inserted into the large end of the stepped hole and pressed against the stepped surface of the stepped hole; the fastener passes through the end cap 14 and is connected to the rotating post 1224. After the insertion protrusion 1223 is inserted into the insertion groove 131, the fastener is then passed through the end cap 14 and connected to the rotating column 1224. Since the end cap 14 is pressed against the stepped surface of the stepped hole at this time, the rotating column 1224 is axially fixed in the stepped hole. At the same time, through the cooperation of the insertion protrusion 1223 and the insertion groove 131, the fixing seat 13 and the base 122 can be radially fixed, thereby ensuring that the antenna 10 is locked and will not shake. After the fastener is loosened, the rotating column 1224 is moved out of the stepped hole, and at the same time, the insertion protrusion 1223 is also moved out of the insertion groove 131. The base 122 is rotated to adjust the antenna 10 to the desired angle, and then the fastener is locked to fix the antenna 10 at the desired angle, thereby realizing the adjustment of the antenna 10 angle or folding.

[0068] In this embodiment, the fastener is a screw, bolt, or screw. When the fastener is a screw, a fixing hole 142 is provided on the end cap 14, and a blind hole 12242 is provided on the rotating column 1224. The screw passes through the fixing hole 142 and is threaded into the blind hole 12242. In addition, the fixing hole 142 is a countersunk hole, so the head of the screw is located in the countersunk hole and the screw does not protrude from the fixing seat 13. During the use of the antenna 10, it will not scratch other parts, and the safety of use is good.

[0069] In this embodiment, the axis of the rotating column 1224 coincides with the center of the annular array of insertion grooves 131. This eliminates the need to remove the fasteners; simply loosening the fasteners allows the insertion protrusion 1223 to move out of the insertion groove 131. Then, the base 122 can be rotated around the axis of the rotating column 1224 to adjust the antenna 10. This eliminates the need to completely disassemble the base 122 and the fixed base 13, making the operation simpler. In addition, the rotating column 1224 provides support and guidance for the rotation of the base 122, making the rotation of the base 122 easier to operate.

[0070] In the embodiments of this application, combined with Figure 2 and Figure 3 As shown, the end face of the rotating column 1224 is provided with a limiting hole 12241, and the end cover 14 is provided with a limiting post 141. The limiting post 141 is inserted into the limiting hole 12241. In this way, the end cover 14 will not rotate during the process of loosening the fastener, thus avoiding damage to the end face due to rotation.

[0071] In another embodiment of this application, combined with Figure 5 As shown, the inner wall of the rotating hole 132 of the antenna 10 has an annular groove 134 at the position corresponding to the lead wire 123 extending from the side of the rotating column 1224. The channel 133 is connected to the annular groove 134, and the lead wire 123 passes through the annular groove 134 and then electrically connects to the external component via the channel 133. In this way, as the rotating column 1224 rotates within the rotating hole 132, the lead wire 123 moves accordingly within the annular groove 134, preventing the lead wire 123 from interfering with the fixed base 13 and protecting the lead wire 123.

[0072] In another embodiment of this application, combined with Figure 3 As shown, the channel 133 of the provided antenna 10 includes a through hole 1331 and a receiving groove 1332. The receiving groove 1332 is formed on the surface of the fixing base 13 near the external component. The through hole 1331 is located between the annular groove 134 and the receiving groove 1332, and connects the receiving groove 1332 and the annular groove 134. During use, the wire 123 led out from the rotating column 1224 enters the through hole 1331 through the annular groove 134 and then leads out from the side of the receiving groove 1332 before connecting to the external component. In specific use, part of the wire 123 can be stored in the receiving groove 1332, so that the wire 123 can extend and retract during the rotation of the antenna 10, avoiding damage to the wire 123.

[0073] In another embodiment of this application, combined with Figure 3 and Figure 5As shown, the mounting base 13 of the antenna 10 has a notch 135 at the end where the rotating post 1224 is inserted into the rotating hole 132, which communicates with the annular groove 134. During the installation of the rotating post 1224 into the rotating hole 132, a portion of the wire 123 extending from the side of the rotating post 1224 can pass through the notch 135, thus smoothly entering the annular groove 134. This prevents the wire 123 from being squeezed between the rotating post 1224 and the rotating hole 132, protecting the wire 123 and preventing damage to the wire 123 that could render the antenna 10 unusable.

[0074] In the embodiments of this application, the fasteners are screws, bolts, and screws.

[0075] In another embodiment of this application, combined with Figure 6 As shown, a lighting device 20 is provided, including the antenna 10 described above.

[0076] The lighting device 20 of this application embodiment uses the aforementioned antenna 10, which has good explosion-proof performance and meets the usage requirements of explosion-proof locations. Therefore, the lighting device 20 can achieve wireless transmission in explosion-proof locations.

[0077] In this embodiment, the mounting base 13 is fixed to the side of the top cover 21 of the lighting device 20 by fasteners. The top cover 21 is equipped with a control board, and the conductor core of the wire 123 is electrically connected to the control board to achieve control.

[0078] In another embodiment of this application, a method for manufacturing an antenna 10 is provided, which includes the following steps:

[0079] Provides housing 11, launching element 121, wire 123, first mold and second mold;

[0080] The transmitter 121 is placed into the first mold, and the wire 123 is electrically connected to the transmitter 121. The transmitter 121 and the wire 123 are then fixed in the first mold. Material is then poured into the first mold. After the material solidifies, a base 122 is obtained covering the connection between the transmitter 121 and the wire 123, thus obtaining the antenna transmitting mechanism 12.

[0081] After the housing 11 is fitted onto the transmitter 121, the housing 11 and the antenna transmitting mechanism 12 are placed and fixed in the second mold. Then, material is poured into the second mold, and after the material solidifies, the housing 11 and the base 122 are connected. The material used for pouring can be plastic. Furthermore, the material of the base 122 can be the same as or different from the material at the connection between the housing 11 and the base 122. Of course, in other embodiments, the material used for pouring can also be other materials.

[0082] Specifically, the designed transmitter 121 is first placed into the first mold, and then the wire 123 is electrically connected to the transmitter 121. The transmitter 121 and the wire 123 are then fixed in the first mold. Material is then injected into the first mold, and after the material solidifies, a base 122 is obtained. The base 122 serves to fix the transmitter 121 and the wire 123 and to seal the parts. This is a one-time molding. Subsequently, the housing 11 and the antenna transmitting mechanism 12 are placed in the second mold for a second molding. After the housing 11 and the antenna transmitting mechanism 12 formed in the first molding are placed in the second mold, a second casting is performed to cast the two together. This is a two-time molding. In this way, the antenna 10 of the present application embodiment is obtained. By casting twice, an antenna 10 with explosion-proof performance is obtained, which can achieve the explosion-proof effect.

[0083] In this embodiment, the base 122, end cap 14, and screws of the antenna 10 obtained through secondary molding are assembled together to form the finished product. Figure 1 The wireless explosion-proof antenna 10 can achieve the effect of explosion protection.

[0084] The transmitter 121 is also obtained by casting. Specifically, the electronic components are placed in the third mold, and then plastic is injected into the third mold. After the plastic covers the electronic components and solidifies, the outer shell is obtained, thus obtaining the injection-molded transmitter 121.

[0085] The conductor 123 is also obtained by casting. Specifically, the conductor core is fixed in the fourth mold, and then plastic is injected into the fourth mold. After the plastic covers the conductor core, it is cured to obtain a protective layer, thus obtaining the injection-molded conductor 123.

[0086] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
