Description

Technical Field

[0001] This invention relates to the field of terminal technology, and in particular to a wiring terminal and terminal equipment. Background Technology

[0002] Indoor wireless terminal routers / access points (APs) offer two power supply options: local power and centralized power. Local power requires a power adapter and a compatible power outlet, making it unsuitable for large-scale, flexible indoor deployments due to limitations imposed by interior design. Therefore, centralized power is commonly used for larger-scale indoor deployments of wireless routers / APs. In centralized power, the upstream device transmits power to the distributed wireless routers / APs via cables, requiring terminals at both ends of the cable for connection to the devices at those ends.

[0003] Therefore, the design of terminals needs to consider how to ensure the reliability of the terminals while achieving quick wiring. Summary of the Invention

[0004] This invention discloses a terminal block and terminal device for ensuring the reliability of the terminal block while achieving rapid wiring.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] In a first aspect, a terminal block includes: a first cover, a second cover, a connector, and a terminal assembly;

[0007] The terminal assembly includes a wiring portion and a connecting portion. The wiring portion is installed inside the second cover, and the connecting portion is connected to the wiring portion and extends outside the second cover.

[0008] The first cover is rotatably mounted on the second cover. The first cover has a closing position and an opening position relative to the second cover. When the first cover is in the closing position, the first cover closes onto the second cover and is used to cooperate with the second cover to crimp the cable to the connector. The first cover and the second cover are fixed relative to each other by the connector. When the first cover is in the opening position, an opening is formed between the first cover and the second cover, which is away from the connector.

[0009] In the aforementioned terminal block, one side of the first cover is rotatably mounted on the second cover, allowing the first cover to have both a closed and an open position relative to the second cover. This side of the first cover is referred to as the connecting side. When wiring is required, the first cover is flipped to the open position. At this time, the connecting side of the first cover remains connected to the second cover, forming an angle between the opening and the connecting portion in the terminal assembly. This facilitates placing the cable between the first and second covers, ensuring that the cable core contacts the connecting portion of the terminal assembly. Then, the first cover is flipped to the closed position, pressing the cable core against the connecting portion to achieve conductivity. The first and second covers are then fixed by connectors, thus completing the wiring of the terminal block. Therefore, the wiring process of the terminal block provided by this embodiment is simple to operate, requiring no special tools for quick completion. Furthermore, the use of connectors to secure the first and second covers ensures that the cable is pressed against the connecting portion by the first and second covers and will not come off due to excessive pulling, improving the reliability of the terminal block.

[0010] In some embodiments, one side of the first cover is rotatably mounted to the second cover via a pivot or hinge.

[0011] In some embodiments, a crimping assembly is provided between the wiring portion and the first cover for crimping the cable and the wiring portion;

[0012] The crimping assembly includes a crimping groove and a crimping plate; the crimping groove is used to position the cable.

[0013] The crimping plate is used to press the cable against the connector so that the cable makes contact with the connector for electrical connection.

[0014] In some embodiments, the crimping groove is formed on the side of the wiring portion facing the first cover body for positioning the cable;

[0015] The first cover has the pressure plate formed on the side facing the second cover.

[0016] In some embodiments, the crimping groove is a V-shaped groove.

[0017] In some embodiments, a pressing assembly is provided between the second cover and the first cover for fixing the cable;

[0018] The pressing assembly includes a pressing groove and a pressing plate that mates with the pressing groove;

[0019] The pressing plate is used to press the cable against the pressing groove.

[0020] In some embodiments, the second cover has the pressing groove formed on the side facing the first cover, and the first cover has the pressing plate formed on the side facing the second cover.

[0021] In some embodiments, the pressing plate is provided with a concave-convex structure at one end facing the pressing groove.

[0022] In some embodiments, the concave-convex structure is toothed.

[0023] In some embodiments, the wiring portion includes a first pin and a second pin electrically connected to the connection portion, the first pin and the second pin being respectively used for electrical connection with a cable;

[0024] An insulating baffle is provided inside the second cover, and the insulating baffle is located between the first pin and the second pin.

[0025] In some embodiments, the wiring portion includes a circuit board and a connecting terminal, the circuit board being located inside the second cover, and the connecting terminal being connected to the circuit board and protruding outside the second cover; the wiring terminal also includes a first foolproof structure located on the side of the wiring terminal near the connecting terminal.

[0026] The first foolproof structure is used to align the terminal block and the terminal device when the terminal block is applied to the terminal device.

[0027] In some embodiments, the first misalignment prevention structure includes a first alignment protrusion and a first alignment groove, wherein:

[0028] The first alignment protrusion is formed on the first cover, and the first alignment groove is formed on the second cover; or...

[0029] The first alignment protrusion is formed on the second cover, and the first alignment groove is formed on the first cover.

[0030] In a second aspect, the present invention also provides a terminal device, including a device body and a wiring terminal as described in the first aspect; the wiring terminal is detachably connected to the device body;

[0031] When the terminal block is provided with a first anti-foolproof structure, the device body is provided with a second anti-foolproof structure that is compatible with the first anti-foolproof structure. Attached Figure Description

Detailed Implementation

[0042] First, let's introduce the application scenario of this application: indoor wireless terminal routers / AP products, with two power supply solutions: local power supply and centralized power supply. Local power supply requires a power adapter and a power outlet, and its installation is limited by interior decoration, making it unsuitable for large-scale flexible indoor deployment. Therefore, centralized power supply is commonly used when deploying wireless routers / APs on a larger scale indoors. In centralized power supply, the upstream device transmits power to the wireless routers / APs distributed in various locations via cables, so terminals need to be installed at both ends of the cable for connection to the devices at both ends. The selected terminals need to meet the requirements of easy installation, high reliability, small size (small terminal size can effectively reduce device size), low cost, and improved product quality. The power supply terminals used should meet these requirements as much as possible simultaneously, which is a problem that product designers need to consider. Currently, commonly used power supply terminals include crimped copper lugs, phoenix-head terminals, and RJ45 terminals. However, crimped copper lugs have low reliability and pose safety hazards; phoenix-head terminals have an industrial appearance, which lowers the aesthetic appeal of home communication products; and RJ45 terminals are bulky, taking up significant equipment space and making installation inconvenient. In short, the commonly used power supply terminals all have some shortcomings. Therefore, there is an urgent need for a terminal block that is small in size, aesthetically pleasing, and can meet the needs of on-site wiring operations.

[0043] Based on the above application scenarios, this application provides a wiring terminal and terminal equipment. The wiring terminal is small in size and occupies little space, and the wiring operation is simple and quick with high reliability.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Firstly, such as Figures 1 to 3As shown, this embodiment of the invention provides a terminal block 100, including: a first cover 110, a second cover 120, a connector 140, and a terminal assembly 150; the terminal assembly 150 includes a wiring portion 151 and a connecting portion 152, the wiring portion 151 is installed inside the second cover 120, and the connecting portion 152 is connected to the wiring portion 151 and protrudes outside the second cover 120; one side of the first cover 110 is rotatably installed on the second cover 120. The first cover 110 has a closing position and an opening position relative to the second cover 120. When the first cover 110 is in the closing position, the first cover 110 closes onto the second cover 120 and is used to cooperate with the second cover 120 to crimp the cable to the connector 151. The first cover 110 and the second cover 120 are fixed relative to each other by the connector 140. When the first cover 110 is in the opening position, the first cover 110 and the second cover 120 form an angle between the opening and the connector 152.

[0046] In the aforementioned terminal block 100, one side of the first cover 110 is rotatably mounted on the second cover 120, so that the first cover 110 has a closed position and an open position relative to the second cover 120. This side of the first cover 110 is referred to as the connection side. When wiring is required, the first cover 110 is flipped to the open position. At this time, the connection side of the first cover 110 is still connected to the second cover 120, and forms an opening at an angle away from the connection part 152 in the terminal assembly 150. This facilitates the quick placement of the cable between the first cover 110 and the second cover 120, and makes the core of the cable contact the connection part 151 of the terminal assembly 150. Then, the first cover 110 is flipped to the closed position, and the first cover 110 presses the core of the cable onto the connection part 151 to achieve conductivity. The first cover 110 and the second cover 120 are fixed by the connector 140, thereby completing the wiring of the terminal block 100. Therefore, the wiring process of the terminal block 100 provided in this embodiment of the invention is simple and can be completed quickly without special tools. At the same time, the connector 140 is used to fasten the first cover 110 and the second cover 120, so that the cable is pressed onto the wiring part 151 by the first cover 110 and the second cover 120, and will not come off due to strong pulling, thus improving the reliability of the terminal block 100.

[0047] In some embodiments, one side of the first cover 110 is rotatably mounted to the second cover 120 via a pivot 130.

[0048] In one possible implementation, refer to Figures 1-3Both the first cover 110 and the second cover 120 are cuboid structures. Along their length, a pivot 130 is located on the first side of the first cover 110, and the first side of the second cover 120 has a shaft hole that mates with the pivot 130. For example, the pivot 130 on the first cover 110 consists of two segments with overlapping axes and a gap. When the first cover 110 and the second cover 120 are installed, the portion of the second cover 120 with the shaft hole is located between the two segments of the pivot 130. The two segments of the pivot 130 are inserted into the shaft hole from both ends, enabling a flip-out connection between the first cover 110 and the second cover 120. Along their length, a connector 140 is located on the second side of the first cover 110 and connects to the second side of the second cover 120 to fix the first cover 110 and the second cover 120 when the first cover 110 is in the closed position.

[0049] In some embodiments, one side of the first cover 110 is rotatably mounted to the second cover 120 via a hinge.

[0050] It should be noted that in the wiring terminal 100 involved in this embodiment, the first cover 110 and the second cover 120 can also be flipped by hinges. Therefore, the flipping of the first cover 110 and the second cover 120 by hinges is also within the protection scope of this invention.

[0051] It is understandable that connector 140 can specifically be a captive screw. Captive screws are also called non-removable screws or anti-loosening screws, see reference [link / reference] Figure 1 The lock-on screw is secured to the first cover 110 by adding a small-diameter screw rod 141 (or by a retaining clip) to prevent it from falling out. The screw structure itself does not prevent it from falling out; this is achieved through the connection between the screw and the first cover 110, either through a retaining clip or by directly clamping the small-diameter screw rod into the mounting hole of the first cover 110. When the terminal block 100 is being wired, the first cover 110 is flipped to the open position, and the lock-on screw is installed on the first cover 110, in a lock-on state. Figure 3 As shown, the captive screw is secured in the mounting hole of the first cover 110 by a small-diameter screw, and the second cover 120 is provided with a connection hole that mates with the captive screw.

[0052] In some embodiments, a crimping assembly is provided between the wiring portion 151 and the first cover 110 for crimping the cable 200 and the wiring portion 151; the crimping assembly includes a crimping groove 162 and a crimping plate 161; the crimping groove 162 is used to position the cable 200; the crimping plate 161 is used to press the cable 200 against the wiring portion 151 so that the cable 200 and the wiring portion 151 make contact electrical connection.

[0053] In one possible implementation, the terminal assembly 150 includes a connecting portion 152 and a wiring portion 151. The connecting portion 152 is used to connect the entire terminal 100 to other devices, and the wiring portion 151 is used to connect to the cable 200. To improve the reliability of the connection between the wiring portion 151 and the cable 200, a crimping assembly is provided between the wiring portion 151 and the first cover 110. The crimping assembly abuts the cable 200 against the wiring portion 151, ensuring a contact electrical connection between the cable 200 and the wiring portion 151. It should be noted that the crimping assembly includes a crimping groove 162 and a crimping plate 161. The crimping groove 162 can be used to position the cable 200 to ensure the accuracy of the connection between the cable 200 and the wiring portion 151; the crimping plate 161 is used to provide abutment force to the cable 200 and the wiring portion 151 to ensure the reliability of the connection between the cable 200 and the wiring portion 151.

[0054] In some embodiments, the wiring portion 151 has a crimping groove 162 formed on the side facing the first cover 110 for positioning the cable 200; the first cover 110 has a crimping plate 161 formed on the side facing the second cover 120.

[0055] One possible way to achieve this is, such as Figures 3-5 As shown, the wiring portion 151 has crimping grooves 162 formed on the side facing the first cover 110. The number of crimping grooves 162 corresponds to the number of cables 200, such as... Figure 5 As shown, there are two cables 200, and two crimping slots 162 on the connector 151, each crimping slot 162 accommodating one cable 200. (Refer to...) Figure 3 The number of crimping plates 161 can also correspond to the number of cables 200, that is, there can be two crimping plates 161, each crimping plate 161 cooperating with a crimping groove 162 to crimp one cable 200. In order to improve the force exerted by the crimping plate 161 on each cable 200 and the positioning accuracy of the crimping groove 162, the two crimping grooves 162 and the two crimping plates 161 are respectively located on both sides of the connector 140, that is, as shown in the figure. Figure 4 As shown, along the width direction of the second cover 120, two crimping grooves 162 are symmetrically distributed on both sides of the connecting hole on the second cover 120, and two crimping plates 161 are symmetrically distributed on both sides of the connecting hole on the second cover 120. When the first cover 110 is flipped to the closing position, the force of the connector 140 fixing the first cover 110 and the second cover 120 makes the force of the two sets of crimping plates 161 on the two cables 200 approximately the same, thereby ensuring the connection reliability of the two cables 200.

[0056] In one possible implementation, refer to Figure 3 , Figure 5 and Figure 6 and combined Figure 1Along the length of the second cover 120, from the connecting hole of the connector 140 to the shaft hole of the rotating shaft 130, the wiring portion 151 includes a first zigzag segment L1, a second zigzag segment L2, and a third zigzag segment L3. The first zigzag segment L1 and the second zigzag segment L2 are approximately perpendicular, and the second zigzag segment L2 and the third zigzag segment L3 form an acute angle with the opening facing the first zigzag segment L1. A crimping groove 162 is provided on the first zigzag segment L1. For example... Figure 7 and Figure 8 As shown, when the connector 151 connects to the cable 200, the core of the cable 200 is placed in the crimping groove 162 and extends between the second folded segment L2 and the third folded segment L3. The crimping plate 161 presses against the third folded segment L3, so that the third folded segment L3 and the second folded segment L2 clamp the end of the core of the cable 200, thereby achieving a reliable contact electrical connection between the connector 151 and the cable 200. For ease of explanation, Figure 8 The third fold line segment that is not pressed is represented by a dashed line. After the crimping plate 161 presses down on the third fold line segment, the third fold line segment is tightly attached to the wire core of the cable 200.

[0057] It should be noted that the main function of the crimping groove 162 is to position the wire core of the cable 200. Therefore, the shape of the crimping groove 162 can be a U-shaped groove, a V-shaped groove, or an arc-shaped groove.

[0058] In some embodiments, the crimping groove 162 is a V-shaped groove.

[0059] In one possible implementation, a V-groove is formed on the first folded segment. Since the bottom size of the V-groove is small, when the crimping plate 161 presses against the third folded segment, the force makes the wire core of the cable 200 closer to the bottom of the crimping groove 162. That is, the wire core can have a snapping force with the bottom of the crimping groove 162 to prevent the wire core from coming out of the crimping groove 162.

[0060] In some embodiments, a pressing assembly is provided between the second cover 120 and the first cover 110 for fixing the cable 200; the pressing assembly includes a pressing groove 172 and a pressing plate 171 that cooperates with the pressing groove 172; the pressing plate 171 is used to press the cable 200 against the pressing groove 172.

[0061] In one possible implementation, the terminal assembly 150 includes a connecting portion 152 and a wiring portion 151. The connecting portion 152 is used to connect the entire terminal 100 to other devices, and the wiring portion 151 is used to connect to the cable 200. To improve the reliability of the connection between the wiring portion 151 and the cable 200, a clamping assembly is provided between the first cover 110 and the second cover 120. The clamping assembly clamps the cable 200 between the first cover 110 and the second cover 120, preventing the cable 200 from losing contact with the wiring portion 151 due to excessive pulling. It should be noted that the clamping assembly includes a clamping groove 172 and a clamping plate 171 that mates with the clamping groove 172. The clamping plate 171 is used to press the cable 200 against the clamping groove 172, which serves to prevent pull-out and improve reliability.

[0062] In some embodiments, a pressing groove 172 is formed on the side of the second cover 120 facing the first cover 110, and a pressing plate 171 is formed on the side of the first cover 110 facing the second cover 120.

[0063] One possible way to achieve this is, such as Figures 3-5 As shown, the second cover 120 has a pressing groove 172 formed on the side facing the first cover 110. The number of pressing grooves 172 corresponds to the number of cables 200, such as... Figure 5 As shown, there are two cables 200, and two crimping grooves 172 on the second cover 120, each crimping groove 172 accommodating one cable 200. (Refer to...) Figure 3 The number of pressing plates 171 can also correspond to the number of cables 200, that is, there can be two pressing plates 171, each pressing plate 171 cooperating with a pressing groove 172 to press one cable 200. In order to improve the force exerted by the pressing plate 171 on each cable 200 and the positioning accuracy of the pressing groove 172, the two pressing grooves 172 and the two pressing plates 171 are respectively located on both sides of the connector 140, that is, as shown in the figure. Figure 4 As shown, along the width direction of the second cover 120, two pressing grooves 172 are symmetrically distributed on both sides of the connecting hole on the second cover 120, and two pressing plates 171 are symmetrically distributed on both sides of the connecting hole on the second cover 120. When the first cover 110 is flipped to the closing position, the force of the connector 140 fixing the first cover 110 and the second cover 120 makes the force of the two sets of pressing plates 171 on the two cables 200 approximately the same, thereby ensuring the anti-pull-out reliability of the two cables 200.

[0064] In some embodiments, in order to increase the friction between the pressing plate 171 and the cable 200, the pressing plate 171 is provided with a concave-convex structure 171a at one end facing the pressing groove 172. The concave-convex structure 171a is in direct contact with the outer sheath of the cable 200, and the protrusion in the concave-convex structure 171a can be inserted into the outer sheath of the cable 200 to improve the clamping force of the pressing assembly.

[0065] In some embodiments, the concave-convex structure 171a is toothed, which makes it easier to insert into the outer sheath of the cable 200 and improves gripping force.

[0066] In some embodiments, the wiring portion 151 includes a first pin 151a and a second pin 151b that are electrically connected to the connection portion 152. The first pin 151a and the second pin 151b are respectively used for electrical connection with the cable 200. An insulating baffle 121 is provided inside the second cover 120, and the insulating baffle 121 is located between the first pin 151a and the second pin 151b.

[0067] In one possible implementation, the wiring portion 151 includes a first pin 151a and a second pin 151b. The first pin 151a and the second pin 151b are welded and fixed to the wiring portion 151 and electrically connected to the connecting portion 152. The welded terminal assembly 150 is used as an injection-molded insert and is encapsulated in the second cover 120 during injection molding. The connecting portion 152 is at least partially located outside the second cover 120. To prevent the cable 200 in the first pin 151a from contacting the cable 200 in the second pin 151b and causing a short circuit, an insulating baffle 121 is provided inside the second cover 120. The insulating baffle 121 is located between the first pin 151a and the second pin 151b, separating the cable 200 in the first pin 151a from the cable 200 in the second pin 151b.

[0068] In some embodiments, the wiring portion 151 includes a circuit board 152a and a connection end 152b. The circuit board 152a is located inside the second cover 120, and the connection end 152b is connected to the circuit board 152a and protrudes outside the second cover 120. The wiring terminal 100 also includes a first foolproof structure 300 located on the side of the wiring terminal 100 near the connection portion 152. The first foolproof structure 300 is used to align the wiring terminal 100 and the terminal device when the wiring terminal 100 is applied to the terminal device.

[0069] In one possible implementation, refer to Figures 5-8 The wiring part 151 includes a first pin 151a and a second pin 151b. The connection part 152 includes a circuit board 152a and a connection end 152b. The circuit board 152a is located inside the second cover 120. The first pin 151a and the second pin 151b are fixed to the circuit board 152a by wave soldering. The connection end 152b and the circuit board 152a are an integral structure. The soldered terminal assembly 150 is used as an injection molding insert and is encapsulated in the second cover 120 during injection molding. The connection end 152b is located outside the second cover 120.

[0070] For example, the first pin 151a and the second pin 151b are copper flexible clamping pins. Both the first pin 151a and the second pin 151b include a first bend segment L1, a second bend segment L2, and a third bend segment L3. The third bend segment L3 and the second bend segment L2 clamp the end of the wire core of the cable 200, thereby achieving a reliable contact electrical connection between the connector 151 and the cable 200. The second bend segment L2 is electrically connected to the circuit board 152a of the connector 151, thereby achieving conductivity.

[0071] It should be noted that, when the terminals provided in the embodiments of the present invention are used in the field, such as... Figure 4 and Figure 5 As shown, firstly, the stripped cable 200 is placed in the second cover 120, with the wire core positioned at the V-shaped groove opening of the connector 151. The outer sheath of the cable 200 is placed in the corresponding crimping groove 172 within the second cover 120. Then, the first cover 110 is closed, and the crimping plate 161 forces the wire core into the V-shaped groove of the connector 151. The toothed structure of the crimping plate 171 is used to hold the wire sheath in place, preventing the cable 200 from being pulled out after the first cover 110 is closed. Finally, the connector 140 is tightened for a secure fit. The baffle between the first pin 151a and the second pin 151b prevents accidental short circuits caused by accidental contact between the two pins, thus improving reliability. Figure 7 and Figure 8 The diagram shows a cross-section of the cable 200 after it has been connected to the terminal block. The cable 200 is pressed together by the first cover 110 and the second cover 120. The core portion is pressed tightly into the V-groove of the connector 151 and is connected to the circuit board 152a. The wire core portion is fixed by the pressing plate 171, which prevents pulling and improves reliability.

[0072] In one possible implementation, the terminal block 100 is plugged into other devices, i.e., the plug-in end of the connection end 152b. The front part of the terminal block 100, i.e. the side near the connection end 152b, has a first foolproof structure 300, which can only be plugged into corresponding and compatible devices to prevent accidental insertion into other devices and causing safety hazards.

[0073] In some embodiments, the first misalignment structure 300 includes a first alignment protrusion 310 and a first alignment groove 320, wherein: the first alignment protrusion 310 is formed on the first cover 110 and the first alignment groove 320 is formed on the second cover 120; or, the first alignment protrusion 310 is formed on the second cover 120 and the first alignment groove 320 is formed on the first cover 110.

[0074] In one possible implementation method, continue to refer to Figure 1 and Figure 2The terminal block 100 has a first alignment protrusion 310 at the front of the first cover 110 and a first alignment groove 320 at the front of the second cover 120. The first alignment protrusion 310 and the first alignment groove 320 can serve as insertion protection.

[0075] It should be noted that the terminal block 100 involved in this embodiment can be, but is not limited to, a USB Type-C male connector. As a power terminal block for quick on-site wiring, it solves the problem of the large size and heavy industrial style of commonly used terminal blocks 100 on the market, resulting in a low-end appearance. Furthermore, the terminal block 100 involved in this embodiment adopts a hinge 130 flip-top structure, allowing the cable 200 to be quickly placed inside the terminal block 100. Closing the cover allows the connector 151 to pierce the cable 200, creating conductivity, and then the screws are tightened after closing the cover. Wiring can be completed quickly without special tools, making construction convenient. At the same time, the screw tightening prevents the cable 200 from coming loose due to excessive pulling, improving reliability. Finally, the terminal block 100 involved in this embodiment has a foolproof structure at the front, ensuring it can only be connected to the corresponding compatible device, preventing accidental insertion into other devices and potential safety hazards.

[0076] It should also be noted that, in addition to serving as a power supply terminal, the technical solution in this embodiment can also be used as a data cable terminal or signal cable terminal for field wiring. Besides its application in network equipment, it can also be applied to various terminal devices, vehicles, or industrial control equipment.

[0077] In a second aspect, embodiments of the present invention also provide a terminal device, including a device body 400 and a terminal block 100 as described in the first aspect embodiment; the terminal block 100 is detachably connected to the device body 400; when the terminal block 100 is provided with a first anti-foolproof structure 300, the device body 400 is provided with a second anti-foolproof structure 500 adapted to the first anti-foolproof structure 300.

[0078] One possible way to achieve this is, such as Figure 9 The diagram shows the terminal block 100 connected to its paired device. The interface shell of the device body is equipped with a second alignment groove 420 and a second alignment protrusion 410, which correspond to the first alignment protrusion 310 and the first alignment groove 320 on the terminal block 100. This serves the purpose of ensuring that "only this corresponding connector can be inserted into the female socket of the device body" and "this connector can only be inserted into the device that is compatible with it," thus providing protection and preventing the risk of damage to the device due to misinsertion.

[0079] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the invention. Therefore, if these modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
