[0040] Example 1

[0041] Please see Figures 1-7 , Figure 1A perspective view of an embodiment of the electronic access control power supply 100 of this utility model is shown. The electronic access control power supply 100 includes: a power supply body 1, a quick-connect housing 2, and a connector 3; the power supply body 1 is used to supply power to multiple devices 300 in the access control system, and the quick-connect housing 2 is connected to one side of the power supply body 1. Figure 2 As shown, the quick-connect housing 2 is provided with a plug cavity 21 and a plurality of output terminals 22; the plug end 31 of the plug body 3 is embedded in the plug cavity 21, and a plurality of electrical connection holes 32 are provided on the plug end 31; one end of each output terminal 22 is placed in the power supply body 1 and electrically connected to the power supply body 1, and the other end is set in the plug cavity 21 and placed next to and plugged into an electrical connection hole 32; each electrical connection hole 32 is fixedly connected to a wire 37 at the end away from the output terminal 22.

[0042] The power supply unit 11 includes a power supply housing 11 and a power conversion circuit inside the power supply housing 11, which converts the voltage input from the external power source 200 (such as 110V-260V AC or 12V / 24V DC) into a DC voltage suitable for use by various devices 300 in the access control system, and provides a stable power supply to multiple devices 300 in the electronic access control system (such as card readers, electromagnetic locks, electric locks, etc.) through the internal circuit.

[0043] The quick-connect housing 2 is mounted on one side of the power supply body 1 and fixedly connected to the power supply body 1 to ensure the stability of the quick-connect housing 2. The quick-connect housing 2 has a plug-in cavity 21, with the opening of the plug-in cavity 21 facing the side of the quick-connect housing 2 away from the power supply body 1. Several output terminals 22 are disposed within the quick-connect housing 2. One end of each output terminal 22 is electrically connected to the power supply body 1, and the other end is placed within the plug-in cavity 21 and extends along the path away from the power supply body 1 towards the opening of the plug-in cavity 21. The output terminals 22 are fixedly connected to the quick-connect housing 2 to secure the output terminals 22 and prevent unstable connections between the output terminals 22 and the quick-connect housing 2, which could affect the electrical connection between the output terminals 22 and the wires 37 within the plug-in body 3.

[0044] The external shape and structure of the insertion end 31 of the connector 3 inserted into the insertion cavity 21 are adapted to the spatial shape and size of the insertion cavity 21, so that the insertion end 31 is tightly embedded in the insertion cavity 21. For example... Figure 2 As shown, several wires 37 are inserted into the connector 3 from the end away from the power supply 1 and fixed inside the connector 3. Several electrical connection holes 32 are arranged horizontally along the insertion direction inside the connector 3. Adjacent electrical connection holes 32 are separated by insulating material from the connector 3 to prevent interference between adjacent electrical connection holes 32 when the output terminal 22 is inserted into the electrical connection hole 32. The electrical connection holes 32, wires 37, and output terminals 22 are arranged in a one-to-one correspondence. When the connector 3 is inserted into the connector cavity 21, the output terminal 22 accurately inserts into the corresponding electrical connection hole 32, connecting the corresponding wire 37 of the device 300 to achieve electrical connection, thus distributing power to each device 300 in the access control system.

[0045] This embodiment replaces the traditional connection of the power supply body 1 and wires 37 via screw crimping or welding by setting a quick-connect housing 2 on the power supply body 1 that supplies power to each device 300 in the electronic access control system, and correspondingly setting a plug-in body 3 to be plugged into the quick-connect housing 2. This achieves quick and accurate installation and disassembly of the power supply body 1 and wires 37, thereby improving the work efficiency of technicians, effectively reducing labor and time costs, and achieving fast and reliable wiring. Technicians only need to insert the plug-in body 3 into the plug-in cavity 21 of the quick-connect housing 2 to complete the connection of all output terminals 22 and wires 37, which greatly simplifies the wiring process, reduces the possibility of wiring errors, improves the efficiency of installation and maintenance, improves the stability and reliability of the electronic access control system, and effectively reduces the failure rate caused by loose wiring or poor contact.

[0046] In one implementation of this embodiment, such as Figure 2 As shown, the power supply body 1 includes a power supply housing 11, and a first opening 12 is provided at one end of the power supply housing 11 along its length. The quick-connect housing 2 is installed in the first opening 12.

[0047] like Figure 3 , Figure 4 As shown, the output terminal 22 is located outside the quick-connect housing 2 for electrical connection with the power supply unit 1, as follows. Figure 5 As shown, another part of the output terminal 22 passes through the quick-connect housing 2 and is placed in the plug cavity 21, for insertion into the electrical connection hole 32 of the plug body 3 for electrical connection with the wire 37. Figure 2 As shown, the power supply housing 11 has a cylindrical structure. A first opening 12 is provided on one side along the length of the power supply housing 11. The quick-connect housing 2 is installed inside the first opening 12 and fixedly connected to the power supply housing 11. One end of the quick-connect housing 2 that connects to the output terminal 22 is placed inside the quick-connect housing, preventing the end of the output terminal 22 used for electrical connection with the power supply 1 from being exposed to the outside, thus protecting the output terminal 22 and ensuring the electrical safety of the electronic access control system. By placing one end of the cavity with the insertion cavity 21 outside the power supply housing 11, it is ensured that the connector 3 can be smoothly assembled into the quick-connect housing 2. Furthermore, placing part of the quick-connect housing 2 inside the power supply housing 11 ensures a neat and aesthetically pleasing appearance for the electronic access control power supply 100.

[0048] like Figure 6As shown, the electronic access control power supply 100 also includes a power terminal 16, and the power supply body 1 also includes a circuit board 14 and a power terminal 16. The circuit board 14 and the power supply component 15 are installed inside the power supply housing 11, and the power supply component 15 and the circuit board 14 are electrically connected. A second opening 13 is provided at one end of the power supply housing 11 away from the first opening 12 along the length direction. The power terminal 16 is installed in the second opening 13, and one end of the power terminal 16 is connected to an external power source 200, and the other end is electrically connected to the circuit board 14 to supply power to the circuit board 14 inside the power supply body 1. The first end 221 of the output terminal 22 is electrically connected to the circuit board 14.

[0049] like Figure 6 As shown, a second opening 13 is provided at one end of the power supply housing 11 opposite to the first opening 12 along the length of the power supply housing 11. The power terminal 16 is installed at the second opening 13 and fixedly connected to the power supply housing 11 to ensure a stable connection between the power terminal 16 and the power supply housing 11. The circuit board 14 is installed inside the power supply housing 11 and fixedly connected to the inner wall of the power supply housing 11 to ensure that the circuit board 14 remains relatively stationary with respect to the power supply housing 11, the power terminal 16, and the quick-connect housing 2 during operation. This ensures a stable electrical connection between the external power supply 200 and the power supply body 1, between the power supply body 1 and the output terminal 22 on the quick-connect housing 2, between the quick-connect housing 2 and the connector 3, and between the circuitry within the power supply body 1. The circuit board 14 is installed inside the power supply housing 11 to convert and distribute the current input from the external power supply 200 to the power supply body 1. The circuit board 14 is electrically connected to the power terminal 16 and the output terminal 22 on the quick-connect housing 2 by soldering or other electrofusion connection methods. The power supply unit 15 includes electronic components such as transformers, rectifiers, filters, and capacitors on the circuit board 14. Electronic components such as transformers, rectifiers, filters, and capacitors are arranged on the circuit of the circuit board 14 to convert the power input from the external power supply 200 (such as 110V-260V AC) through the power supply terminal 16 into DC voltage suitable for use by the electronic access control system. The converted current is then distributed and / or stored, and output from the power supply unit 1 through each output terminal 22 and distributed to each device 300.

[0050] like Figure 7As shown, the output terminal 22 has an L-shaped structure. The first end 221 of the output terminal 22 is placed inside the power supply body 1 and electrically connected to the power supply body 1. The second end 222 of the output terminal 22 is located inside the insertion cavity 21 and is inserted into the electrical connection hole 32. The L-shaped output terminal 22 can better adapt to the space constraints inside the power supply housing 11. By setting the output terminal 22 to an L-shaped structure, the first end 221 can be soldered and fixed to the surface of the circuit board 14 in the vertical direction. The second end 222 of the output terminal 22 passes through the plug body 3 in the horizontal direction and exits from the bottom of the plug cavity 21, placing it inside the plug cavity 21. This ensures that the second end 222 of the output terminal 22 is parallel to the insertion direction of the plug body 3 into the plug cavity 21, ensuring tight contact between the output terminal 22 and the electrical connection hole 32, reducing contact resistance, and improving the stability of the electrical connection. At the same time, when assembling the plug body 3 and the quick-connect housing 2, it is only necessary to insert the plug body 3 into the plug cavity 21 to complete the connection of all output terminals 22 and electrical connection holes 32, which greatly simplifies the installation process and reduces wiring time and error rate. This embodiment uses an L-shaped output terminal 22 to simultaneously achieve vertical soldering connection with the circuit board 14 and horizontal plug-in connection with the electrical connection hole 32. This not only optimizes space utilization and improves the stability and reliability of the connection, but also simplifies the installation and maintenance process.

[0051] Several markings (not shown in the figure) are provided on the upper surface of the power supply housing 11. Each marking corresponds to the output terminal 22 at a relative position and is used to identify different output terminals 22.

[0052] Several output terminals 22 are arranged in a regular manner, and several labels are arranged in a regular manner on the upper surface of the power supply housing 11 in the direction of the output terminals 22. Each label corresponds to an output terminal 22. During installation and maintenance, technicians can quickly identify the function or connection object of each output terminal 22, reduce wiring errors caused by misoperation, and significantly improve the efficiency of installation and maintenance.

[0053] The functions or connection objects corresponding to several output terminals 22 include: 12V positive terminal, GND negative terminal, PUSH signal output terminal, electromagnetic lock GND negative terminal, electric control lock NO positive terminal, exit switch terminal, auxiliary power positive terminal, door magnetic signal terminal, backup power terminal, etc.

[0054] In one implementation of this embodiment, such as Figure 7 As shown, a conductive element 36 is provided in the plug body 3. One end of each wire 37 is embedded in the plug body 3 and is crimped and fixed to the conductive element 36. The end of the conductive element 36 away from the wire 37 is placed in the electrical connection hole 32 and electrically connected to the output terminal 22.

[0055] Along the length of the conductive element 36, one end of the conductive element 36 is fixed in contact with the insulation layer of the wire 37, and the other end is placed inside the electrical connection hole 32 and has a sheet-like structure. Its surface is curved to tightly fit and contact the surface of the second end 222 of the output terminal 22 to achieve electrical connection. At the same time, the curved end of the conductive element 36 can tightly fit with the sidewall of the electrical connection hole 32 to avoid obstructing the insertion of the second end 222 when the output terminal 22 is inserted into the electrical connection hole 32. The middle end of the conductive element 36 is pressed and connected to the metal conductive part of the wire 37 to achieve electrical connection between the wire 37 and the wire 37 component. By fixing the conductive element 36 in the plug body 3, the insulation layer and metal conductive part of the wire 37 are fixed to the conductive element 36, so that the wire 37 and the plug body 3 are stably connected. At the same time, the conductive element 36 achieves electrical connection between the wire 37 and the second end 222 of the output terminal 22.

[0056] In one implementation of this embodiment, such as Figure 3 As shown, a protrusion 33 extending in a direction away from the bottom of the connector 3 is provided at the bottom of the connector 3, and a slot 23 adapted to the protrusion 33 is provided at the bottom of the connector cavity 21. When the connector 3 is inserted into the connector cavity 21, the protrusion 33 at the bottom of the connector 3 engages with the slot 23 at the bottom of the quick-connect cavity 21, and the protrusion 33 is embedded in the slot 23 to fix the connector 3 and the quick-connect housing 2, preventing the connector 3 from sliding out of the connector cavity 21 of the quick-connect housing 2.

[0057] like Figure 4 As shown, the protrusion 33 includes a wide section 331 and a narrow section 332 that are connected to each other, with the wide section 331 being closer to the power supply body 1 than the narrow section 332; the slot 23 includes a wide slot 231 and a narrow slot 232 that are connected to each other, with the wide slot 231 being closer to the power supply body 1 than the narrow slot 232; the protrusion 33 is placed in the slot 23, with the wide section 331 being accommodated in the wide slot 231 and the narrow section 332 being accommodated in the narrow slot 232. In the insertion direction of the connector 3 into the connector cavity 21, the wide slot 231 of the slot 23 is closer to the power supply body 1 than the narrow slot 232, and the wide segment 331 of the protrusion 33 is closer to the power supply body 1 than the narrow segment 332. When the protrusion 33 is placed in the slot 23, the wide segment 331 of the protrusion 33 is placed in the wide slot 231 of the slot 23, and the narrow segment 332 is placed in the narrow slot 232. When there is a tendency for the connector 3 and the connector cavity 21 to slide out relative to each other, the narrow slot 232 of the slot 23 restricts the wide segment 331 of the protrusion 33 from sliding in the slot 23, so as to prevent the connector 3 from sliding out of the connector cavity 21.

[0058] like Figure 7 As shown, a plurality of grooves 34 are provided on the top of the plug body 3, and an elastic element 35 is provided in each groove 34. One end of the elastic element 35 is fixedly connected to the plug body 3, and the other end is placed outside the groove 34.

[0059] In one implementation, the protrusion is made of an elastic material. When the connector 3 is inserted into the connector cavity 21 but the protrusion 33 is not assembled with the slot 23, the protrusion 33 is in a compressed state. When the protrusion 33 is placed in the slot 23, the protrusion 33 is in a free state. The connector 3 is fixed in the connector cavity 21 by assembling the protrusion 33 with the slot 23.

[0060] In another implementation, an elastic element 35 is provided at the top opposite to the bottom of the plug body 3. When the plug body 3 is placed in the plug cavity 21, the elastic element 35 at the top of the plug body 3 will press and abut against the top of the plug cavity 21, fixing the plug body 3 in the plug cavity 21, further improving the connection between the plug body 3 and the quick-connect housing 2, and improving the stability of the electrical connection between the output end of the power supply body 1 and each device 300.

[0061] Simultaneously, the compression between the elastic element 35 and the top of the insertion cavity 21 causes the elastic force generated by the compressed elastic element 35 to act on the insertion body 3, causing the protrusion 33 at the bottom of the insertion body 3 to embed into the slot 23. This prevents the protrusion 33 from leaving the slot 23 in the vertical direction, thus avoiding displacement of the insertion body 3 and the insertion cavity 21 in the horizontal direction, which would affect the electrical connection between the insertion body 3 and the quick-connect housing 2. In this embodiment, by setting the elastic element 35 at the top of the insertion body 3, the elastic element 35 is compressed by contacting the top of the insertion cavity 21, further fixing the insertion body 3 in the insertion cavity 21. At the same time, the elastic force generated by the elastic element 35 acts on the insertion body 3, causing the insertion body 3 to move closer to the bottom of the insertion cavity 21, preventing the protrusion 33 from sliding out of the slot 23. This further improves the connection between the insertion body 3 and the quick-connect housing 2, and enhances the stability of the electrical connection between the output end of the power supply 1 and each device 300.

[0062] In the vertical direction, the length of the protrusion 33 extending away from the bottom of the connector 3 is greater than the depth of the slot 23. When the protrusion 33 is placed in the slot 23, part of the protrusion 33 passes through the slot 23 in the vertical direction and protrudes from the bottom of the quick-connect housing 2. When it is necessary to disassemble the connection between the connector 3 and the quick-connect housing 2, the protrusion 33 located outside the bottom of the quick-connect housing 2 is manually pressed to make the protrusion 33 enter the connector cavity 21 and move out of the slot 23. The connector 3 is then quickly pulled out of the connector cavity 21 by external force.

[0063] When the elastic element 35 is a spring (illustrated in the figure), one end of the spring is fixed in the groove 34 in the vertical direction, and the other end extends in the vertical direction and is placed outside the groove 34. When the spring and the insertion cavity 21 are pressed together, the spring is compressed and moves into the groove 34. The groove 34 is used to accommodate the elastic element 35 and ensure that the elastic element 35 is not over-compressed, thus protecting the elastic element 35, improving the service life of the elastic element 35, and thereby improving the service life of the insertion body 3.

[0064] In another implementation, such as Figure 7 As shown, the elastic element 35 has a curved structure. In the insertion direction of the connector 3 into the connector cavity 21, the end of the elastic element 35 away from the power source 1 is the fixed end 351, and the end closer to the power source 1 is the free end 352. The fixed end 351 is placed at the end of the groove 34 away from the power source and is fixedly connected to the connector 3. In the vertical direction, it gradually extends away from the groove 34 from the fixed end 351 to the free end 352, so that in the vertical direction, the free end 352 is suspended. The free end 352 is positioned outside the groove 34 and spaced apart from the bottom of the groove 34. When the plug body 3 enters the plug cavity 21, the free end 352 is pressed against the top of the plug cavity 21, causing the free end 352 to move vertically toward the bottom of the groove 34. At this time, the fixed end 351 of the elastic member 35 provides the free end 352 with an elastic force pointing vertically toward the top of the plug cavity 21, thereby increasing the compressive force between the free end 352 and the top of the plug cavity 21, and firmly fixing the plug body 3 in the plug cavity 21.

[0065] In another implementation, the protrusion 33 and the groove wall of the slot 23 increase the friction between them through compression contact, thereby fixing the protrusion 33 in the slot 23 and preventing the connector 3 from sliding out of the connector cavity 21 of the quick-connect housing 2. In this embodiment, the protrusion 33 and the slot 23 are rigidly connected, and the connector 3 is fixed in the connector cavity 21 by the friction between the protrusion 33 and the slot 23, as well as the friction between the connector 3 and the inner wall of the connector cavity 21.

[0066] This utility model provides an electronic access control power supply 100 and an access control system. The electronic access control power supply 100 includes a power supply body 1, a quick-connect housing 2, and a connector 3. The quick-connect housing 2 is installed on one side of the power supply body 1 and fixed to the power supply body 1 to ensure a stable connection between the quick-connect housing 2 and the power supply body 1. A connector cavity 21 is provided in the quick-connect housing 2. By inserting or pulling out part of the connector 3 into the connector cavity 21, the speed of wiring and disconnecting the wires 37 and the power supply body 1 is improved. This simplifies the operation process for technicians and ensures the stability and accuracy of the electrical connection between the connector 3 and the power supply body 1 when the quick-connect housing 2 is connected to the connector 3. Several output terminals 22 are provided in the quick-connect housing 2. One end of the output terminal 22 is electrically connected to the power supply body 1, and the other end is placed in the plug-in cavity 21. One end of several wires 37 is fixed in the plug-in body 3, realizing the integrated setting of the output end of the power supply body 1. A plug-in hole is provided on the side of the plug-in body 3 that is inserted into the plug-in cavity 21. After one output terminal 22 is inserted into one electrical connection hole 32, it is electrically connected to one wire 37 fixed in the plug-in body 3. This replaces the electrical connection method between the wire 37 and the power supply body 1 in the traditional electronic power access control, realizing fast and reliable wiring, shortening the wiring time, avoiding the possibility of wiring errors, simplifying the electrical connection between the power supply body 1 and the wire 37, and making the overall structure neat and simple in appearance.
