[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figures 1 to 5 In an embodiment of the utility model, a conversion cable for a Lightning interface to an RS-422 interface that is convenient to connect includes a connecting cable 1, one end of the connecting cable 1 is connected to the RS-422 interface 2, and the other end is connected to the Lightning interface 3. A latch structure 4 is provided in the RS-422 interface 2, and a cable fixing device 5 is movably connected to the connecting cable 1. The cable fixing device 5 is provided with a snap structure 6, and the Lightning interface 3 is provided with a snap groove 7. The snap structure 6 and the snap groove 7 are snap-connected.
[0021] Two mounting grooves 21 are relatively provided in the S-422 interface 2, and the latch structure 4 is composed of two latch assemblies relatively arranged in the mounting grooves 21. The latch assembly includes a pressing column 41, a limiting plate 42, a connecting rod 43, a spring 44 and a latch 45. The pressing column 41 is slidably connected in the mounting groove 21, and one end of the pressing column 41 extends out of the mounting groove 21. One end of the pressing column 41 in the mounting groove 21 is fixedly connected to the limiting plate 42, and the limiting plate 42 is slidably connected to the mounting groove 21. The other side of the limiting plate 42 is fixedly connected to the connecting rod 43, and the other end of the connecting rod 43 is fixedly connected to the latch 45. The latch 45 is slidably connected to the mounting groove 21, and a spring 44 is provided on the outer sleeve of the connecting rod 43.
[0022] When connecting the RS-422 interface 2 to the elevator, the RS-422 interface 2 is inserted into the female end of the elevator. During the insertion process, the pin 45 is subjected to a thrust and moves into the installation slot 21. When the pin 45 moves to the slot of the female end, under the action of the spring 44, the pin 45 is driven to be inserted into the slot for locking. At this time, the RS-422 interface 2 is fully inserted into the female end of the elevator. The plug-in connection method can prevent the interface from loosening or falling off due to accidental pulling, vibration or movement. The connection is more stable and the continuity of data transmission is ensured. When the adapter cable needs to be unplugged, press the pressing columns 41 on both sides inward. The pressing columns 41 drive the pin 45 to move inward, thereby releasing the lock on the female end and canceling the adapter cable. The operation is convenient.
[0023] The cable fixing device 5 includes a fixing base 51, a first rubber pad 52, a spring piece 53, a second rubber pad 54 and an adsorption magnet 55. A circular through hole is provided in the fixing base 51. The first rubber pad 52 is fixedly connected to one side of the fixing base 51. The first rubber pad 52 abuts against the connecting line 1. Two spring pieces 53 are provided on the inner wall of the fixing base 51 above the first rubber pad 52. One end of the spring piece 53 is fixedly connected to the inner wall of the fixing base 51, and the other end is in the fixing base 51. The side of the spring piece 53 abutting against the connecting line 1 is fixedly connected to the second rubber pad 54. The bottom of the fixing base 51 is fixedly connected to the adsorption magnet 55.
[0024] By adsorbing the adsorption magnet 55 onto the elevator, the connecting cable 1 is fixed, which can reduce the movement of the connecting cable 1, reduce the risk of loosening the interface, and ensure that the connection between the mobile phone and the elevator control system is always stable and reliable; and the spring clip 53, the first rubber pad 52 and the second rubber pad 54 in the fixing seat 51 can protect the connecting cable 1 from damage while buffering the shaking of the connecting cable 1. When encountering unexpected pulling or vibration during use, the spring clip 53, the first rubber pad 52 and the second rubber pad 54 can absorb part of the force, reduce the vibration impact on the RS-422 interface, reduce the risk of loosening the connector, and ensure the reliability of the connection.
[0025] The buckle structure 6 is composed of multiple buckle components, which include a connecting plate 61 and a buckle body 62. The connecting plate 61 is fixedly connected to the top of the fixing seat 51, and two buckle bodies 62 are provided, which are fixedly connected to both sides of the connecting plate 61.
[0026] The RS-422 interface 2 is provided with anti-slip grooves 22, which can make it easier for the operator to exert force when plugging and unplugging the adapter cable, thereby achieving quick plugging and unplugging.
[0027] The working principle of the present invention is as follows: when using the adapter cable for converting the Lightning interface to the RS-422 interface that is easy to connect, the Lightning interface 3 is connected to the mobile phone, and the RS-422 interface 2 is connected to the elevator. When the RS-422 interface 2 is connected to the elevator, the RS-422 interface 2 is inserted into the female end on the elevator. During the insertion process, the latch 45 is subjected to a thrust and moves into the installation slot 21. When the latch 45 moves to the slot of the female end, under the action of the spring 44, the latch 45 is inserted into the slot for locking. At this time, the RS-422 interface 2 is fully inserted into the female end of the elevator. The plug-in connection method can prevent the interface from loosening or falling off due to accidental pulling, vibration or movement, and the connection is more stable, ensuring the continuity of data transmission. When it is necessary to unplug the cable, the cable can be easily disconnected. When switching cables, press the pressing columns 41 on both sides inward, and the pressing columns 41 drive the pins 45 to move inward, thereby releasing the lock on the female end and canceling the switching cable, which is easy to operate; during use, the adsorption magnets 55 can be adsorbed onto the elevator to fix the connecting cable 1, which can reduce the movement of the connecting cable 1 and the risk of loose interface, ensuring that the connection between the mobile phone and the elevator control system is always stable and reliable, and the spring clip 53 in the fixing seat 51 can buffer the shaking of the connecting cable 1. When encountering unexpected pulling or vibration during use, the spring clip 53 can absorb part of the force. The first rubber pad 52 and the second rubber pad 54 not only protect the connecting cable 1 from damage, but also play a certain buffering role; when the switching cable is not in use, the snap structure 6 and the snap groove 7 can be snap-connected for easy storage.
[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
