Abstract
Description
Technical Field
[0001] This utility model relates to the field of access control controllers, specifically to a multi-door access control controller. Background Technology
[0002] Access control systems, also known as entry and exit management control systems, are developed from traditional door locks. The access controller is the core of the system, which combines modern computer technology and various identification technologies to embody an intelligent management approach. A multi-door access controller refers to the setting of using one access controller to control multiple access points simultaneously.
[0003] In the existing technology, the four-door one-way access control controller with model number G-AN401N mainly includes: access control controller body, wires, power supply and other electrical components. In order to avoid damage to the access control controller during use, which may cause malfunction of the access control switch, these electrical components need to be fixed inside the protective housing (chassis). The fixing method can be screw fixing. During the fixing process, the access control controller body is installed at the upper end of the inner cavity of the protective housing, and the power supply is fixed at the lower end of the inner cavity of the protective housing. A gap needs to be left between the two to facilitate the wire to pass through and form an electrical connection with the access control controller body and the power supply.
[0004] However, during the wiring process, there are many wires and they run in different directions. In order to avoid mess or tangling, it is necessary to fix the wires with the same direction vertically. At present, most methods are to use bracing tape to bind the wires.
[0005] However, after securing the wires with cable ties, the excess cable ties need to be cut off using a cutting device. This process can easily damage the power supply surface. Furthermore, when a single wire needs to be repaired or replaced later, the cable ties need to be cut again using the cutting device. After the repair is completed, new cable ties need to be used for securing the wires. This operation is inconvenient and cannot be reused. In addition, when multiple wires are bundled together during the operation of electrical components, the heat at the bundling point cannot be effectively dissipated, which can lead to local temperature increases, causing the power supply to age and affecting its service life. Summary of the Invention
[0006] The purpose of this invention is to solve the problems mentioned in the background section.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A multi-door access control controller includes a protective housing and a controller body and a power supply installed inside the protective housing. The power supply is located below the controller body. A ribbon cable board is installed on the inner wall of the protective housing. The ribbon cable board is located between the controller body and the power supply. A groove is formed in the middle of the ribbon cable board, and cable bundling holes are formed at intervals on the surfaces of both ends of the ribbon cable board.
[0009] After the controller and power supply are installed inside the protective housing, the ribbon cable board is installed and fixed between them. The connecting wires can then be routed horizontally through the grooves inside the ribbon cable board. When the wires need to be routed upwards or downwards to connect to the controller or power supply, the wires can be passed through the cable bundling holes, making it easy to bundle multiple wires without the need to use cable ties to secure them.
[0010] Preferably, the lower end of the protective shell is provided with symmetrical through holes, and the inner wall of the protective shell is provided with fixing holes.
[0011] The wires can pass through the through holes to penetrate the protective housing, and the mounting holes facilitate the fixing of the ribbon cable board, placing the ribbon cable board between the controller body and the power supply.
[0012] Preferably, the ribbon cable has lugs symmetrically welded at both ends, and heat dissipation grooves are formed on the inner wall surface of the ribbon cable.
[0013] The ribbon cable board is fixed to the inner wall of the protective shell by lugs, and when multiple wires are confined to the inside of the groove, the wires inside the groove near the inner wall of the ribbon cable board can dissipate heat through the heat dissipation slots.
[0014] Preferably, the wire hole is arranged in a U-shape.
[0015] This allows the wires to move freely inside the cable tray.
[0016] Preferably, the inner walls at both ends of the wire harness hole are symmetrically provided with limiting holes, a movable groove is provided on one side surface of the limiting hole, and a limiting plate is movably connected inside the limiting hole.
[0017] The limiting plate can be extended and adjusted through the limiting hole to easily seal the opening of the wire harness hole and prevent the wire inside the limiting hole from coming off.
[0018] Preferably, a buffer spring is fixedly installed at one end of the limiting plate, and a baffle is fixedly installed on the outer wall of the end of the limiting plate near the buffer spring, the baffle movably passing through the movable groove.
[0019] When the limit plate is pressed and retracted into the limit hole, the buffer spring will be squeezed and deformed. When the limit plate is released, the buffer spring will rebound the limit plate. The baffle moves through the movable groove, which can limit the limit plate and prevent the limit plate from being bounced out of the limit hole by the buffer spring.
[0020] Preferably, the two sides of the end of the limiting plate away from the buffer spring are set in an arc shape.
[0021] To avoid damage to the surface of the wire when the limit plate comes into contact with the wire surface.
[0022] The beneficial effects of this utility model are:
[0023] 1. This utility model can bundle and separate multiple wires by setting up a ribbon cable. The ribbon cable is fixed horizontally between the controller body and the power supply. When the wires run horizontally, they can pass through the groove in the middle of the ribbon cable. When the wires need to run vertically to connect with the controller body and the power supply, they can pass through the bundle holes. There is no need to use cable ties to bind and fix the wires. The operation is simple and convenient and can be reused multiple times.
[0024] The ribbon cable board is fixed to the inner wall of the protective shell by the lugs. When multiple wires are confined to the inside of the groove, the wires inside the groove that are close to the inner wall of the ribbon cable board can dissipate heat through the heat dissipation groove, thus preventing the wires in that position from being pressed against the inner wall of the ribbon cable board and the heat from not being able to dissipate in time.
[0025] 2. This utility model can limit the wire inside the wire harness hole by setting a limiting plate. The limiting plate can be adjusted by extending and retracting through the limiting hole to conveniently seal the opening of the wire harness hole and prevent the wire inside the limiting hole from detaching. The two sides of the end of the limiting plate away from the buffer spring are set in an arc shape to avoid damage to the surface of the wire when the limiting plate comes into contact with the surface of the wire.

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0033] See attached document Figure 5 The existing product structure includes a protective housing 1 and a controller body 2 and a power supply 3 installed inside the protective housing 1. The power supply 3 is located below the controller body 2. The protective housing 1 is a box structure. The front of the protective housing 1 is hinged with a door, which is convenient to protect the front of the protective housing 1 when maintenance is not required. The four corners of the back of the protective housing 1 have first mounting holes, which are convenient for screws to pass through and fix the protective housing 1 to the wall. The upper and lower back of the inner cavity of the protective housing 1 are provided with second mounting holes, which are convenient for fixing the controller body 2 and the power supply 3 to the inner cavity of the protective housing 1. The lower end of the protective housing 1 has symmetrical through holes 11, which are convenient for multiple wires from the outside of the protective housing 1 to pass through the through holes 11 and enter the inner cavity of the protective housing 1, so that each wire can form an electrical connection with the corresponding position of the controller body 2 and the power supply 3.
[0034] See attached document Figures 1-3This utility model provides a multi-door access control controller. A cable tray 4 is installed on the inner wall of the protective housing 1. When the wires are not connected to the controller body 2 and the power supply 3, the cable tray 4 is first horizontally fixed to the inner cavity of the protective housing 1. A fixing hole 12 is provided on the inner wall of the protective housing 1, located between the controller body 2 and the power supply 3, so that the cable tray 4 will also be located between the controller body 2 and the power supply 3 after installation. Lugs 41 are symmetrically welded to both ends of the cable tray 4, and a central hole is provided in the middle of each lug 41. The diameter of the central hole is the same as that of the fixing hole 12, facilitating screw penetration for fixing the cable tray 4. After the cable tray 4 is fixedly installed, its two ends do not contact the sides of the inner cavity of the protective housing 1, leaving a gap for wires to pass through. A groove 5 is provided in the middle of the cable tray 4. When the wires need to be routed horizontally, they can be confined to the inside of the groove 5. The two ends of the cable board 4 are provided with cable bundling holes 6 at intervals. When the wires need to be routed vertically, they can pass through the cable bundling holes 6 and be confined inside the cable bundling holes 6. The wires will not contact each other. The cable bundling holes 6 are U-shaped, which facilitates the movement of the wires inside the cable bundling holes 6. (When the number of wires exceeds the number of cable bundling holes 6, making the cable bundling holes 6 insufficient, the cable bundling holes 6 can accommodate several wires at the same time. When the number of cable bundling holes 6 is sufficient, only one wire needs to be confined inside each cable bundling hole 6.) The inner wall surface of the cable board 4 is provided with heat dissipation grooves 42. When multiple wires are confined to the inside of the groove 5, the wires inside the groove 5 that are close to the inner wall of the cable board 4 can be dissipated through the heat dissipation grooves 42.
[0035] Based on the above structure, the present invention includes the following embodiments:
[0036] When the wires are not connected to the controller body 2 and the power supply 3, the ribbon cable 4 is first fixed horizontally in the inner cavity of the protective shell 1, so that the ribbon cable 4 is located between the controller body 2 and the power supply 3. After the ribbon cable 4 is fixed, the wires can pass through the through hole 11 into the inner cavity of the protective shell 1. Then the wires can be run horizontally through the groove 5. When the wires need to be run vertically up and down to connect with the controller body 2 and the power supply 3, the wires can pass through the cable bundling hole 6, so that the wires are located inside the cable bundling hole 6. The inner wall surface of the ribbon cable 4 is provided with heat dissipation grooves 42. When multiple wires are limited to the inside of the groove 5, the wires inside the groove 5 near the inner wall of the ribbon cable 4 can be dissipated through the heat dissipation grooves 42.
[0037] See attached document Figures 3-4This utility model provides a multi-door access control controller. The inner walls of both ends of the cable tray 6 are symmetrically provided with limiting holes 61. A movable groove 62 is provided on one side of each limiting hole 61. The limiting holes 61 and the movable groove 62 are located at the end of the cable tray 4 away from the inner wall of the protective housing 1. A limiting plate 63 is movably connected inside the limiting hole 61. The limiting plate 63 can be adjusted by extending and retracting through the limiting hole 61 to conveniently seal the opening of the cable tray 6, preventing the wires inside the limiting hole 61 from detaching. A buffer spring 632 is fixedly installed at one end of the limiting plate 63. When the limiting plate 63 is pressed... When the 3rd plate retracts into the limiting hole 61, the buffer spring 632 will be squeezed and deformed. When the limiting plate 63 is released, the buffer spring 632 will rebound the limiting plate 63. A baffle 631 is fixedly installed on the outer wall of the end of the limiting plate 63 near the buffer spring 632. The baffle 631 moves through the movable groove 62 and can limit the limiting plate 63 to prevent the limiting plate 63 from being rebounded out of the limiting hole 61 by the buffer spring 632. The two sides of the end of the limiting plate 63 away from the buffer spring 632 are set in an arc shape to prevent the limiting plate 63 from damaging the surface of the wire when it comes into contact with the wire surface.
[0038] Based on the above structure, the present invention includes the following embodiments:
[0039] When the wire is confined inside the cable tie hole 6, the limiting plate 63 will be pushed out of the limiting hole 61 by the buffer spring 632, so that the limiting plate 63 can limit and block the wire. When it is necessary to remove the wire, the limiting plate 63 can be pulled back into the limiting hole 61 by the baffle 631. At this time, the buffer spring 632 will be squeezed and deformed, and the wire can also be removed through the opening of the cable tie hole 6. When the baffle 631 is released, the buffer spring 632 will push back the limiting plate 63. At this time, due to the limitation of the baffle 631 by the movable groove 62, the limiting plate 63 will not separate from the limiting hole 61.
[0040] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
