[0002] The IoT terminal is a device that connects the sensor network layer and the transmission network layer in the IoT to collect data and send data to the network layer. It is responsible for multiple functions such as data collection, preliminary processing, encryption, and transmission. Various types of IoT terminal devices can be generally divided into a situational awareness layer, a network access layer, a network control layer, and an application / business layer.

[0003] IoT terminals are used in various fields. In the field of industrial equipment detection, such terminals are usually installed on large equipment in factories or large moving machinery in industrial and mining enterprises. They are used to collect various sensor data, such as displacement, position, vibration, liquid level, pressure, temperature, etc., and send them to the central processing platform through some wired interfaces for data processing and analysis, so as to realize real-time monitoring of equipment status and safe production.

[0004] With respect to the above-mentioned related technologies, the inventors have discovered that when an IoT terminal is deployed near mechanical equipment, the mechanical equipment may be subjected to some mechanical vibrations or parts collisions while performing tasks or moving, which may cause the plug of the IoT terminal to vibrate and become loose or fall off, and cause short circuits, etc., which may also affect the normal operation of the mechanical equipment. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide an Internet of Things terminal with stable plugging, so as to prevent the plug of the Internet of Things terminal from loosening or falling off due to amplitude, thereby ensuring the normal operation of mechanical equipment.

The elastic characteristics are used to fix and limit the cable, and the card interface clamps the elastic arc-shaped locking piece to make it in close contact with the cable, thereby preventing the plug part from being vibrated and causing loosening or falling off.

[0010] In a preferred example, the utility model can be further configured as follows: the ends of the two elastic arc-shaped locking pieces facing each other and away from the L-shaped protective clamping plate are respectively arranged close to each other.

[0011] By adopting the above technical solution, the two facing elastic arc-shaped locking pieces are tapered as a whole, which further limits and fixes the cable, and under the action of the card body and the card interface, the elastic arc-shaped locking pieces are locked as a whole to fix the cable.

[0016] In a preferred example, the utility model can be further configured as follows: one end of the card body away from the mounting plate is always located outside the protective shell, and one end of the card body away from the mounting plate is provided with a pull-out slot.

After the plug is plugged in, the elastic arc-shaped locking piece is tightened in conjunction with the card plate body and the locking groove, so that the inner side of the elastic arc-shaped locking piece is in close contact with the cable.

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] It should be noted that these drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0032] Reference Figure 1-5, is a plug-in stable Internet of Things terminal disclosed by the utility model, comprising: an Internet of Things terminal body 1 and a plurality of heat dissipation fins 2 connected to the surface thereof, a mounting plate 3 connected to one side of the Internet of Things terminal body 1, a cable plug-in mechanism 4 is provided at one end of the Internet of Things terminal body 1, and a signal transmission mechanism 5 is provided at the other end, a protective shell 6 is installed at one end of the Internet of Things terminal body 1 close to the cable plug-in mechanism 4, and two guide limit rods 7 are symmetrically installed at one end of the protective shell 6 away from the signal transmission mechanism, and the guide limit rods 7 are respectively arranged close to the mounting plate 3, and also include a clamping plate assembly 80, the clamping plate assembly 80 includes an L-shaped protective clamping plate 81, and the two ends of the L-shaped protective clamping plate 81 are respectively slidably connected to the guide limit rod 7, after the L-shaped protective clamping plate 81 moves toward the Internet of Things terminal body 1, the L-shaped protective clamping plate 81 is located on the inner side of the protective shell 6, and a plurality of cable ports 82 are spaced apart on the L-shaped protective clamping plate 81, and at least one arc-shaped clearance groove 83 is respectively opened on both sides of the cable port 82, and the arc-shaped clearance grooves 83 are respectively arranged symmetrically, and the arc-shaped clearance grooves 83 are respectively arranged symmetrically. The side away from the IoT terminal body 1 is respectively connected with an elastic arc-shaped locking piece 84, and the ends of the two opposite elastic arc-shaped locking pieces 84 away from the L-shaped protective splint 81 are respectively arranged close to each other, and the side of the protective shell 6 away from the guide limit rod 7 is penetrated with a sliding card assembly 90, and the sliding card assembly 90 includes a card body 91, and the card body 91 is provided with a card interface 92 corresponding to the cable port 82, and the card body 91 and the L-shaped protective splint 81 are staggered, and the L-shaped protective splint 81 is located between the card body 91 and the IoT terminal body 1. Between the terminal body 1, locking grooves 94 matching the elastic arc-shaped locking pieces 84 are respectively opened on both sides of the card interface 92. After the clamping plate assembly 80 moves toward the Internet of Things terminal body 1 and the sliding card assembly 90 moves toward the mounting plate 3, the corresponding locking groove 94 drives the outer end of the corresponding elastic arc-shaped locking piece 84 to move toward the inner side of the cable opening 82. The longest distance between the two opposing elastic arc-shaped locking pieces 84 is greater than the diameter of the cable, and the shortest distance between the two opposing elastic arc-shaped locking pieces 84 is less than the diameter of the cable.

[0033] The cable plug-in mechanism 4 is a plurality of connection sockets and a plurality of cable plug-in ports, the signal transmission mechanism 5 is an antenna, and a plurality of mounting holes are provided on the mounting plate 3 for fixing and mounting with bolts. The number of the cable ports 82 matches the connection sockets and the cable plug-in ports on the cable plug-in mechanism 4, and the positions also correspond to each other. After the L-shaped protective splint 81 moves away from the Internet of Things terminal body 1 on the guide limit rod 7, a clearance is formed between the L-shaped protective splint 81 and the protective shell 6 for connecting the plug to the corresponding socket. After the plug is connected, the cable is placed on the opposite side. In the corresponding cable port 82, it can also ensure that the line is tidy and convenient for subsequent maintenance. At this time, the two opposing elastic arc-shaped locking pieces 84 initially limit the corresponding cables, and because the outer ends of the elastic arc-shaped locking pieces 84 are close to each other, their overall tapered shape can effectively limit the cables between the elastic arc-shaped locking pieces 84. Subsequently, the staff drives the card plate body 91 to move toward the guide limit rod 7, and tightens the locking groove 94 to tighten the elastic arc-shaped locking piece 84, so that the inner side of the elastic arc-shaped locking piece 84 is in close contact with the cable, thereby preventing the plug part from being vibrated and causing loosening or falling off.

[0034] Sliding openings 11 are respectively provided on both sides of the protective shell 6, and sliders 93 are respectively connected to both sides of the card body 91, and the sliders 93 are respectively slidably connected to the corresponding sliding openings 11; the card body 91 and the slider 93 are an integrally formed structure, preferably made of plastic or acrylic material. After the L-shaped protective splint 81 is reset close to the Internet of Things terminal body 1, the card body 91 moves toward the guide limit rod 7. At this time, the slider 93 moves in the sliding opening 11, and after the cable is fixed, the interior of the protective shell 6 presents a protective cavity, which ensures that the plug is inserted stably, and can also reduce dust and prevent poor contact and the like.

[0035] The end of the card body 91 away from the mounting plate 3 is always located outside the protective shell 6, and a pull-out slot 95 is provided at the end of the card body 91 away from the mounting plate 3; the staff pulls the pull-out slot 95 by hand to move the card body 91 closer to or away from the protective shell 6, thereby adjusting the elastic arc-shaped locking piece 84 to a locked state, so that the cable connector can be plugged in or maintained.

[0036] The implementation principle of this embodiment is: when in use, the staff plugs the corresponding connector into the connecting socket on the cable plug-in mechanism 4, and then places the cable part in the corresponding cable port 82. At this time, the cable is located between the corresponding arc-shaped yielding grooves 83, and because the outer ends of the elastic arc-shaped locking pieces 84 are close to the overall conical shape, and combined with the elastic arc-shaped locking pieces 84's own elasticity, the cable can be effectively limited between the elastic arc-shaped locking pieces 84. Then the staff drives the card body 91 to move toward the guide limiting rod 7 by pulling the slot 95, so that the locking slot 94 makes the corresponding two elastic arc-shaped locking pieces 84 move toward each other and tighten. At this time, the inner side of the elastic arc-shaped locking piece 84 is in close contact with the cable, thereby preventing the plug part from being vibrated and causing loosening or falling off.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
