Description

Technical Field

[0001] This invention relates to the field of connector technology, and more specifically to a smart gateway connector that is easy to plug and unplug. Background Technology

[0002] With the rapid development of IoT and Industrial Internet technologies, smart gateways, as the core hubs for device interconnection, data transmission, and protocol conversion, have been widely applied in various fields. The stable operation of industrial smart gateways directly depends on the reliable transmission of signals and power. Connectors, as key components enabling electrical connections between industrial smart gateways and external devices and transmission lines, have a crucial impact on the stability and maintenance efficiency of the entire system due to their connection performance and ease of use. Whether it's the routine debugging of consumer-grade industrial smart gateways or the inspection and maintenance of industrial smart gateways in industrial scenarios, connectors must possess the core characteristics of quick plugging / unplugging and stable connection.

[0003] In practical applications, industrial smart gateways operate in complex and diverse environments. Some scenarios (such as workshop production lines and outdoor communication equipment) are often accompanied by mechanical vibrations and accidental collisions. Existing connectors mostly adopt traditional plug-in structures, relying solely on the friction between the male and female heads for fixation, lacking a reliable locking mechanism. This results in connectors that are not tightly connected, and when subjected to external mechanical impacts or vibrations, the male and female heads are prone to loosening or even detachment. This not only interrupts the data transmission and power supply of the industrial smart gateway, affecting the normal operation of the system, but may also cause signal interference and equipment failure due to poor contact. Summary of the Invention

[0004] This invention provides an easy-to-plug smart gateway connector to solve the problem that existing connectors are not tight enough, and the male and female heads are prone to loosening and falling off under external mechanical impact or vibration, affecting the stable use of the connector.

[0005] The present invention provides an easy-to-plug smart gateway connector, comprising a male and a female connector; the male connector is movable toward the female connector along a first direction and plugs into the female connector, the direction in which the male and female connectors are plugged in is referred to as the first direction; the male connector includes a base and multiple plug groups, the multiple plug groups being arranged sequentially on the base along a second direction, the second direction being perpendicular to the first direction; each plug group includes a insert and a probe, in the initial state the base, insert, and probe are all arranged along the first direction, the insert is fixedly connected to the base, and the probe is rotatably connected to the base; the insert is an elastic sheet, in its natural state the insert is perpendicular to the second direction. The cross-section of the slot is arc-shaped. The female end has a slot for mating with the insert and a hole for mating with the insert rod. The two ends of the slot along the first direction are called the head end and the tail end, respectively. The head end is located on the side of the tail end closer to the male end in the first direction, and the size of the head end in the second direction is larger than the size of the tail end in the second direction. The two inner wall surfaces of the slot along the third direction are elastic surfaces, and the third direction is perpendicular to the first and second directions, respectively. The base can rotate relative to the insert and the insert rod around the second direction, and when the base rotates clockwise relative to the insert and the insert rod around the second direction, the two ends of the insert along the second direction can move away from each other.

[0006] Furthermore, the plug assembly also includes a rotating wheel, which is fixed to one end of the plug rod. The rotating wheel is a ratchet, and a ratchet bar is provided on the base. The ratchet bar is installed on the base through a first elastic element. When the ratchet bar is engaged with the rotating wheel, the rotating wheel only allows the base to rotate clockwise relative to the rotating wheel in a second direction. When the ratchet bar is disengaged from the rotating wheel, the rotating wheel and the base can rotate relative to each other in a second direction. In the initial state, the ratchet bar is engaged with the rotating wheel.

[0007] Furthermore, a limit group is provided inside the female head. The limit group includes two limit holes and two limit blocks. The two limit holes are arranged side by side in the second direction and are both opened on the female head. Each limit hole is connected to a limit block through a second elastic member. The second elastic member is arranged along the second direction and always has the tendency to cause the limit block to move away from its corresponding limit hole along the second direction. In the initial state, the limit block is engaged in its corresponding limit hole, and the base can disengage the limit block from its corresponding limit hole by rotating in the same direction relative to the rotating wheel.

[0008] Furthermore, the plug-in assembly also includes a push rod, which is arranged along the first direction and passes through the plug rod and the rotating wheel in sequence. The push rod is installed on the plug rod through a third elastic element. The two ends of the push rod along the first direction are respectively referred to as the first end and the second end. The first end is located on the side of the second end closer to the rotating wheel in the first direction. A push block is connected to the base through a fourth elastic element. In the initial state, the push rod and the push block are arranged in sequence in the first direction. The push block extends into the rotating wheel and the first end of the push rod abuts against the push block. The end faces of the two limiting blocks that are close to each other in the second direction are both set as wedge surfaces. Two wedge grooves are opened on the push rod. The two wedge grooves are arranged one-to-one with the two limiting blocks. The movement of the push rod along the first direction can cause the corresponding limiting blocks to extend and retract along the second direction.

[0009] Furthermore, a first sliding groove is provided on the insertion rod, and a second sliding groove is provided on the rotating wheel. The first and second sliding grooves are sequentially arranged and interconnected in the first direction. The push rod is slidably installed in the first and second sliding grooves, and the end face of the push block that abuts against the push rod is an arc-shaped surface.

[0010] Furthermore, a push groove is provided on the base, and the push block and the fourth elastic element are both installed in the push groove.

[0011] Furthermore, multiple limit groups are provided, and multiple limit groups are arranged sequentially in the first direction inside the female head; multiple wedge-shaped grooves are opened on the push rod, and every two wedge-shaped grooves are called a mating group, and multiple limit groups and multiple mating groups are arranged one-to-one.

[0012] Furthermore, there are two insertion rods, which are respectively located on both sides of the corresponding insertion piece in the second direction.

[0013] Furthermore, the insert has slots at both ends along the second direction, the two slots are arranged side by side in the second direction, and a protrusion is provided in the slot, the protrusion is located on one side of the tail end of the slot, and the protrusion can engage with the slot.

[0014] Furthermore, the insert includes an insertion segment, a bending segment, and an installation segment. In the initial state, the insertion segment, the bending segment, and the installation segment are arranged sequentially in the first direction and fixedly connected to each other. The installation segment is fixedly connected to the base, the insertion segment is inserted into the insertion hole, the bending segment connects the insertion segment and the installation segment, and the base can be rotated around the second direction to make the bending segment bend around the second direction.

[0015] The beneficial effects of this invention are as follows: The easy-to-plug smart gateway connector of this invention, by setting multiple plug groups on the base, allows the base to rotate clockwise relative to the plug and the plug rod in a second direction when the male connector is plugged into the female connector. This causes the two ends of the plug in the second direction to move away from each other, making the plug flatter. During insertion, the plug minimizes contact with the two inner walls of the slot in the third direction, making it easier for the plug to move from the beginning to the end of the slot, reducing the difficulty of insertion. Furthermore, because the size of the beginning of the slot in the second direction is larger than that of its end in the second direction, the plug is deformed by the slot as it moves, allowing the two ends of the plug in the second direction to move closer together. This results in the two ends of the plug in the third direction being supported within the slot, making the insertion tighter and improving the stability of the male and female connectors. This prevents the male and female connectors from easily coming loose, effectively avoiding problems such as signal interruption and unstable power supply caused by loose connections, ensuring the long-term stable operation of the smart gateway. After the male and female connectors are connected, the base is rotated in reverse relative to the connector and the plug bar to return to the initial state in the second direction. This causes the two ends of the connector to move closer to each other along the second direction, further ensuring the tightness of the connector and the slot. By rotating the base to change the deformation state of the connector, the difficulty of the connection process is reduced, the connection strength of the male and female connectors after connection is improved, and the user experience and system reliability of the smart gateway are enhanced.

Detailed Implementation

[0028] 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.

[0029] An embodiment of the present invention, a smart gateway connector that is easy to plug and unplug, is as follows: Figures 1 to 10 As shown.

[0030] A pluggable smart gateway connector includes a male connector 100 and a female connector 200. The male connector 100 is movable toward the female connector 200 in a first direction and can be plugged into the female connector 200. The direction in which the male connector 100 and the female connector 200 are plugged in is referred to as the first direction. See appendix. Figure 1 As shown, the first direction is the direction indicated by the X-axis.

[0031] The male connector 100 includes a base 110 and multiple plug groups. The base 110 is an insulator, and the multiple plug groups are all conductors. The multiple plug groups are arranged sequentially on the base 110 along a second direction, which is perpendicular to the first direction. (See attached diagram) Figure 1 As shown, the second direction is the direction indicated by the Y-axis.

[0032] The plug assembly includes a insert 120 and a plug rod 130. In the initial state, the base 110, insert 120 and plug rod 130 are all arranged along the first direction, and the insert 120 is fixedly connected to the base 110, while the plug rod 130 is rotatably connected to the base 110. The insert 120 is an elastic sheet, and in its natural state, the cross section of the insert 120 perpendicular to the second direction is arc-shaped.

[0033] The female connector 200 has a slot for mating with the insert 120 and a hole for mating with the insert rod 130. The two ends of the slot along the first direction are referred to as the head end and the tail end, respectively. The head end is located on the side of the tail end closer to the male connector 100 in the first direction, and the size of the head end in the second direction is larger than that of the tail end in the second direction. Both inner wall surfaces of the slot along the third direction are elastic surfaces, specifically rubber surfaces. That is, the slot provides sufficient space for the deformation of the insert 120 in the third direction. The third direction is perpendicular to both the first and second directions; see appendix. Figure 1 As shown, the third direction is the direction indicated by the Z-axis.

[0034] The base 110 is rotatable relative to the insert 120 and the insert rod 130 about a second direction, and when the base 110 rotates clockwise relative to the insert 120 and the insert rod 130 about the second direction, the two ends of the insert 120 along the second direction can move away from each other. Clockwise rotation is... Figure 6 The counter-clockwise direction of the shown viewpoint, rotating in the opposite direction to the attached Figure 6 The clockwise direction of the viewpoint shown.

[0035] In this embodiment, multiple plug-in groups are provided on the base 110. When the male connector 100 is plugged into the female connector 200, the insert 120 is aligned with its corresponding slot, and the plug rod 130 is aligned with its corresponding socket. The base 110 is held to insert the insert 120 and the plug rod 130. First, the insert 120 and the plug rod 130 are partially inserted. Then, the base 110 is manually rotated so that the base 110 rotates clockwise relative to the insert 120 and the plug rod 130 in a second direction. Since the insert 120 is fixed to the base 110 and the plug rod 130 is rotatably connected to the base 110, the deformation position of the insert 120 can be limited by the plug rod 130, preventing the end of the insert 120 inserted into the female connector 200 from rotating and deforming, so that the insert 120 can be connected to the base 110. One end is rotated and deformed, thereby deforming the entire part of the insert 120 to be inserted. That is, the two ends of the insert 120 along the second direction can move away from each other, and the insert 120 will become flatter. During insertion, by flattening the insert 120, the insert 120 is made to avoid contact with the two inner wall surfaces of the slot along the third direction as much as possible. Therefore, the insert 120 will be easier to move from the first end to the last end of the slot, reducing the insertion difficulty of the insert 120 and the slot (compared to not flattening).

[0036] Furthermore, because the size of the first end of the slot in the second direction is larger than the size of its tail end in the second direction, as the insert 120 moves continuously, the insert 120 will be constrained by the slot and deformed, thereby allowing the two ends of the insert 120 in the second direction to move closer to each other in the second direction, and thus allowing the two ends of the insert 120 in the third direction to be supported in the slot, making the insert 120 and the slot more tightly connected, improving the stability of the male connector 100 and the female connector 200 when they are connected, and making it less likely for the male connector 100 and the female connector 200 to come loose.

[0037] After the male connector 100 and the female connector 200 are connected, the base 110 is rotated in reverse relative to the insert 120 and the insert rod 130 in the second direction to return to the initial state. The reverse rotation of the base 110 will cause the end of the insert 120 connected to the base 110 to rotate and deform, so that the two ends of the insert 120 along the second direction are brought closer to each other, thereby further ensuring the tightness of the insertion of the insert 120 into the slot. By rotating the base 110 to change the deformation state of the insert 120, the difficulty of the insertion process is reduced and the connection strength of the male connector 100 and the female connector 200 after insertion is improved.

[0038] Specifically, the insert 120 includes an insertion section 121, a bending section 122, and a mounting section 123. In the initial state, the insertion section 121, the bending section 122, and the mounting section 123 are sequentially arranged and fixedly connected to each other in a first direction, and the insertion section 121, the bending section 122, and the mounting section 123 are integrally formed. The mounting section 123 is fixedly connected to the base 110, and the insertion section 121 is inserted into the insertion hole. The bending section 122 connects the insertion section 121 and the mounting section 123, and the base 110 can be rotated in a second direction to bend the bending section 122 in the second direction.

[0039] That is, when the base 110 rotates around the second direction, the bending section 122 will bend around the second direction, thereby causing the bending section 122 and the insertion section 121 to deform.

[0040] In this embodiment, the plug-in assembly further includes a rotating wheel 140, which is fixedly connected to one end of the plug rod 130. The rotating wheel 140 is a ratchet with multiple teeth evenly distributed around a second direction, and the teeth are telescopic teeth. A ratchet bar 150 is provided on the base 110, and the ratchet bar 150 is mounted on the base 110 via a first elastic element, which is a spring, allowing the ratchet bar 150 to extend and retract along its own axis. When the ratchet bar 150 is engaged with the rotating wheel 140, the rotating wheel 140 can restrict the base 110 from rotating in the opposite direction relative to the rotating wheel 140 around the second direction, allowing only the base 110 to rotate in the forward direction relative to the rotating wheel 140. When the ratchet bar 150 is disengaged from the rotating wheel 140, the rotating wheel 140 and the base 110 can rotate relative to each other around the second direction. In the initial state, the ratchet bar 150 is engaged with the rotating wheel 140.

[0041] In this embodiment, a rotating wheel 140 is provided at one end of the insertion rod 130, and it engages with the ratchet rod 150 on the base 110. See attached drawing. Figure 8 As shown, in the initial state, the ratchet 150 is engaged with the rotating wheel 140. When the insertion rod 130 is inserted into the insertion hole, since the insertion rod 130 is fixedly connected to the rotating wheel 140, the rotating wheel 140 cannot rotate. Furthermore, since the ratchet 150 is engaged with the rotating wheel 140, the base 110 can only rotate clockwise relative to the rotating wheel 140 in the second direction. This clockwise rotation is... Figure 8The view shown is counterclockwise. Rotation of the base 110 will cause the insert 120 fixed to the base 110 to rotate, thereby flattening the insert 120. Furthermore, the rotating wheel 140 and the ratchet 150 cooperate to restrict the automatic reset of the base 110. When the base 110 needs to be reset after insertion, the operator manually pulls the ratchet 150 and compresses the first elastic element, thereby disengaging the ratchet 150 from the rotating wheel 140. Since the insert 130 and the insert 120 have already been inserted, the relative rotation of the rotating wheel 140 and the base 110 around the second direction is no longer restricted. The operator can manually reverse the rotation of the base 110 around the second direction to reset it. Reversing the rotation is as follows: Figure 8 The clockwise direction of the viewpoint shown.

[0042] In this embodiment, a limiting group is provided within the female head 200. The limiting group includes two limiting holes 210 and two limiting blocks 220. The two limiting holes 210 are arranged side by side in the second direction and are both opened on the female head 200. Each limiting hole 210 is connected to a limiting block 220 through a second elastic member 230. The second elastic member 230 is arranged along the second direction and always has a tendency to cause the limiting block 220 to move away from its corresponding limiting hole 210 along the second direction. In the initial state, the limiting block 220 is engaged in its corresponding limiting hole 210, and the base 110 rotates clockwise relative to the rotating wheel 140 in the second direction, which can disengage the limiting block 220 from its corresponding limiting hole 210.

[0043] Specifically, the plug-in assembly also includes a push rod 160, which is arranged along a first direction and passes sequentially through the plug rod 130 and the rotating wheel 140. The push rod 160 is mounted on the plug rod 130 via a third elastic element 170, which is a spring. The two ends of the push rod 160 along the first direction are referred to as the first end and the second end, respectively. The first end is located on the side of the second end in the first direction closer to the rotating wheel 140. A push block 190 is connected to the base 110 via a fourth elastic element 180, which is also a spring. In the initial state, the push rod 160 and the push block 190 are arranged sequentially in the first direction, with the push block 190 extending into the rotating wheel 140 and the first end of the push rod 160 abutting against the push block 190.

[0044] The end faces of the two limiting blocks 220 that are close to each other in the second direction are both set as wedge surfaces. Two wedge-shaped grooves are formed on the push rod 160, each corresponding to one of the two limiting blocks 220. The push rod 160 moves in the first direction, causing its corresponding limiting block 220 to extend or retract in the second direction, thereby engaging the limiting block 220 within its corresponding limiting hole 210, or disengaging it from its corresponding limiting hole 210. Initially, each wedge-shaped groove is located on the side of its corresponding limiting block 220 away from the rotating wheel 140 in the first direction, and at this time, the limiting block 220 is engaged within its corresponding limiting hole 210. When the base 110 rotates clockwise relative to the rotating wheel 140 in the second direction, each wedge-shaped groove engages with its corresponding limiting block 220, and at this time, the limiting block 220 disengages from its corresponding limiting hole 210.

[0045] More specifically, the insertion rod 130 has a first sliding groove, and the rotating wheel 140 has a second sliding groove. The first and second sliding grooves are arranged sequentially in the first direction and are interconnected. The push rod 160 is slidably installed in the first and second sliding grooves. The end face of the push block 190 that abuts against the push rod 160 is an arc-shaped surface, so that when the base 110 rotates relative to the rotating wheel 140 around the second direction, the push block 190 can leave or enter the second sliding groove with the base 110.

[0046] The base 110 is provided with a push groove, and the push block 190 and the fourth elastic member 180 are both installed in the push groove, so that when the base 110 rotates in a clockwise direction relative to the rotating wheel 140, the push block 190 can leave the second slide groove with the base 110 and enter the push groove, and compress the fourth elastic member 180.

[0047] Furthermore, multiple limit groups are provided, and these limit groups are arranged sequentially along the first direction within the female head 200. Multiple wedge-shaped grooves are provided on the push rod 160, and each pair of wedge-shaped grooves is called a mating group. The multiple limit groups and multiple mating groups are arranged in a one-to-one correspondence.

[0048] This embodiment utilizes a limiting block 220 and a push rod 160 in conjunction; see attached diagram. Figure 6 As shown, in the initial state, the push rod 160 and the push block 190 are arranged sequentially in the first direction, and the first end of the push rod 160 abuts against the push block 190. At this time, the second end of the push rod 160 coincides with the end of its corresponding insertion hole. The third elastic element 170 is in a stretched state, and the fourth elastic element 180 is in a natural state. The limiting block 220 is engaged in its corresponding limiting hole 210.

[0049] When the base 110 rotates clockwise relative to the rotating wheel 140 about the second direction, the base 110 will drive the fourth elastic element 180 and the push block 190 to rotate synchronously, allowing the push block 190 to slide out of the second groove on the rotating wheel 140. The fourth elastic element 180 will be compressed and retracted into the base 110. Without the restriction of the fourth elastic element 180, the third elastic element 170 will reset and pull the push rod 160 to move along the first direction towards the side closer to the rotating wheel 140. See Appendix. Figure 3 and attached Figure 4 As shown, the push rod 160 no longer restricts the movement of the limit block 220, the limit block 220 disengages from its corresponding limit hole 210, and each wedge groove engages with its corresponding limit block 220.

[0050] That is, after the insert 120 is inserted into the slot and the insert rod 130 is inserted into the socket, the limiting block 220 is not engaged with its corresponding limiting hole 210. If the limiting block 220 needs to be engaged with its corresponding limiting hole 210, the base 110 needs to be manually rotated in reverse around the second direction to reset, thereby causing the push block 190 to slide into the second groove again. At this time, the fourth elastic element 180 resets, causing the push rod 160 to move away from the rotating wheel 140 along the first direction, so that the push rod 160 is reset to its initial state. At this time, each wedge groove is located on the side of its corresponding wedge block away from the rotating wheel 140 in the second direction, and the limiting block 220 is engaged in its corresponding limiting hole 210. By using the cooperation of the limiting block 220 and the limiting hole 210, the loosening of the insert rod 130 from the socket is further restricted, making the connection between the male head 100 and the female head 200 tighter.

[0051] Furthermore, two insertion rods 130 are provided, each positioned on one side of its corresponding insertion piece 120 in the second direction. By providing two insertion rods 130, the connection strength between the male connector 100 and the female connector 200 is further improved.

[0052] In this embodiment, the insert 120 has slots 124 at both ends along the second direction. The two slots 124 are arranged side by side in the second direction. A protrusion is provided in the slot. The protrusion is located on one side of the tail end of the slot and can engage with the slot 124.

[0053] By setting the slot 124 and the protrusion to engage, during the process of inserting the insert 120 into the slot, since the insert 120 is in a relatively flat state, the insert 120 will pass over the protrusion when it passes the protrusion. After the insert 120 is inserted into the slot, the slot 124 engages with the protrusion, thereby further improving the stability of the insertion of the insert 120 into the slot.

[0054] Based on the above embodiments, the specific working process is as follows:

[0055] When inserting the male connector 100 into the female connector 200, align the insert 120 with its corresponding slot and the insert rod 130 with its corresponding socket. Hold the base 110 and insert the insert 120 and insert rod 130 together. First, insert the insert 120 and insert rod 130 together. In the initial state, the ratchet 150 is engaged with the rotating wheel 140. When the insert rod 130 is inserted into the socket, since the insert rod 130 is fixed to the rotating wheel 140, the rotating wheel 140 cannot rotate. Furthermore, since the ratchet 150 is engaged with the rotating wheel 140, the base 110 can only rotate clockwise relative to the rotating wheel 140 in the second direction. This clockwise rotation is... Figure 8 The view shown is in the counter-clockwise direction.

[0056] Manually rotate the base 110 so that the insert 120 can rotate and deform at the end connected to the base 110, thereby deforming the part of the insert 120 to be inserted. That is, the two ends of the insert 120 along the second direction can move away from each other, and the insert 120 will become flatter. When inserting, by flattening the insert 120, the insert 120 is made to avoid contact with the two inner wall surfaces of the slot along the third direction as much as possible. Therefore, the insert 120 will be easier to move from the first end to the last end of the slot, reducing the difficulty of inserting the insert 120 into the slot (compared to not flattening).

[0057] Furthermore, because the size of the first end of the slot in the second direction is larger than the size of its tail end in the second direction, as the insert 120 moves continuously, the insert 120 will be constrained by the slot and deformed, thereby allowing the two ends of the insert 120 in the second direction to move closer to each other in the second direction, and thus allowing the two ends of the insert 120 in the third direction to be supported in the slot, making the insert 120 and the slot more tightly connected, improving the stability of the male connector 100 and the female connector 200 when they are connected, and making it less likely for the male connector 100 and the female connector 200 to come loose.

[0058] Furthermore, when the base 110 rotates clockwise relative to the rotating wheel 140 in the second direction, the base 110 will drive the fourth elastic element 180 and the push block 190 to rotate synchronously, allowing the push block 190 to slide out of the second groove on the rotating wheel 140. The fourth elastic element 180 will be compressed and retracted into the base 110. Without the restriction of the fourth elastic element 180, the third elastic element 170 will reset and pull the push rod 160 to move along the first direction towards the side closer to the rotating wheel 140. See Appendix. Figure 3 and attached Figure 4 As shown, the push rod 160 no longer restricts the movement of the limit block 220, the limit block 220 disengages from its corresponding limit hole 210, and each wedge groove engages with its corresponding limit block 220.

[0059] After the male connector 100 and female connector 200 are connected, the operator manually pulls the ratchet 150 and compresses the first elastic element, thereby disengaging the ratchet 150 from the rotating wheel 140. Since the insertion rod 130 and the insert 120 have been connected at this time, the relative rotation of the rotating wheel 140 and the base 110 around the second direction is no longer restricted. The operator can manually reverse the rotation of the base 110 around the second direction to reset it. Reversing the rotation is as follows: Figure 8 The clockwise direction of the viewpoint shown.

[0060] The reverse rotation of the base 110 will cause the end of the insert 120 connected to the base 110 to rotate and deform, so that the two ends of the insert 120 along the second direction are closer to each other, thereby further ensuring the tightness of the insertion of the insert 120 and the slot. The reverse rotation of the base 110 will cause the push block 190 to slide into the second groove again, the fourth elastic element 180 will reset, and the push rod 160 will move away from the rotating wheel 140 along the first direction, so that the push rod 160 is reset to the initial state. At this time, each wedge groove is located on the side of the wedge block corresponding to it that is away from the rotating wheel 140 in the second direction. At this time, the limiting block 220 is engaged in the limiting hole 210 corresponding to it, further restricting the insertion rod 130 from the insertion hole, making the connection between the male head 100 and the female head 200 tighter.

[0061] That is, the easy-to-plug smart gateway connector is designed with a flexible insert 120 that engages with the slot and a plug 130 that engages with the limiting block 220. By rotating the base 110 around the second direction, the engagement state of the insert 120 with the slot and the plug 130 with the limiting block 220 is changed, which reduces the difficulty of the plugging process, improves the connection strength of the male head 100 and the female head 200 after plugging, and ensures the stable use of the easy-to-plug smart gateway connector.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
