Description

Technical Field

[0001] This utility model relates to the field of regional energy technology, and in particular to a data acquisition gateway with an interface designed to prevent disconnection. Background Technology

[0002] In the regional energy sector, data acquisition gateways are responsible for connecting sensors to monitoring platforms, and their reliability is crucial. Currently, gateways primarily use ports and terminal blocks to connect sensor cables.

[0003] In existing technologies, the common connection structure for ports and terminal blocks is the plug-in method. This method is simple in structure, but it is prone to loosening or even falling off due to vibration or pulling, causing data interruption and insufficient reliability. Another type is the terminal block with a locking mechanism, which provides a more stable connection and effectively prevents accidental dislodgement. However, during equipment debugging and maintenance, operators often need to repeatedly plug and unplug the terminal block. Each time, the locking mechanism must be manually unlocked before the terminal block can be removed; when reinstalling, it must be aligned and inserted before the locking mechanism can be relocked. This process of unlocking and relocking for each operation increases the complexity and time cost of debugging and maintenance, reduces work efficiency, and is especially inconvenient during frequent operations.

[0004] Based on this, in order to further improve the connection stability of existing data acquisition gateway ports and terminal blocks, we propose a data acquisition gateway with interface anti-disconnection. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a data acquisition gateway with an interface designed to prevent disconnection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a data acquisition gateway with interface anti-disconnection feature, including:

[0008] The gateway itself is configured with ports;

[0009] A terminal block is detachably connected to the port, a connector is fixedly installed below the terminal block, and a mating seat is fixedly installed on the side of the gateway body. The mating seat contains a locking assembly and a positioning assembly for positioning the locking assembly. The end face of the connector has a locking hole that is adapted to the locking assembly.

[0010] Furthermore, the connector includes two connecting arms and a U-shaped insertion position formed between the two connecting arms, with the locking hole formed on the end face of the U-shaped insertion position.

[0011] Furthermore, the docking seat includes a fixing part and a docking part, the docking part being inserted into the U-shaped insertion position.

[0012] Furthermore, the locking assembly includes a wedge-shaped rod, and at least one stepped hole is provided on the end face of the mating part. The wedge-shaped rod is slidably connected in the stepped hole, and its bottom end extends through to the bottom of the mating part. The bottom end of the wedge-shaped rod is inserted into the locking hole.

[0013] Furthermore, the locking assembly also includes a stop cap threadedly connected to the opening of the stepped hole, a stop platform formed at the top of the wedge rod, and a spring placed between the stop cap and the stop platform.

[0014] Furthermore, the positioning component includes a positioning plate, and the front end of the docking part has a slot communicating with the stepped hole. The positioning plate is slidably connected in the slot, wherein the front end of the wedge rod has a positioning groove that is inserted into the positioning plate.

[0015] Furthermore, the upper end of the docking part is provided with a sliding groove that connects to the slot, the top of the positioning plate is fixedly installed with a toggle post that slides in the sliding groove, the inner wall of the sliding groove is formed with a locking protrusion that stops the toggle post, and the upper end of the docking part is provided with a deformation groove located on the side of the locking protrusion.

[0016] The data acquisition gateway with anti-disconnection interface proposed in this utility model has the following advantages:

[0017] This utility model achieves the purpose of preventing the terminal block from detaching by installing a connector and a mating seat on the terminal block and the gateway body respectively, and using the locking component on the mating seat to achieve a locking connection with the connector.

[0018] In addition, this utility model also includes a positioning component for controlling the locking assembly. The positioning component can keep the locking assembly in a locked state and an unlocked state. For example, during installation, inspection and maintenance, the positioning component can keep the locking assembly in a locked state. At this time, the locking assembly cannot lock the connector. Therefore, in this state, the reciprocating insertion and removal operation of the terminal block and port is supported, thus further improving the applicability of the gateway.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 This utility model discloses a data acquisition gateway with anti-disconnection interface, specifically the gateway includes a gateway body 1 configured with port 10;

[0027] A terminal block 2 is detachably connected to the port 10. The terminal block 2 and the port 10 are movably plugged in. Of course, in order to prevent the terminal block 2 from falling off, a connecting seat 3 is fixedly installed below the terminal block 2 in this embodiment. A docking seat 4 is fixedly installed on the side of the gateway body 1. The docking seat 4 has a locking component 5 and a positioning component 6 for positioning the locking component 5 installed inside. The end face of the connecting seat 3 has a locking hole 30 that is adapted to the locking component 5.

[0028] Specifically, in this embodiment, the connecting seat 3 is connected and fixed to the terminal block 2 by bolts, and the docking seat 4 can also be connected and fixed to the gateway body 1 by bolts. The positioning component 6 is used to lock the locking component 5 so that the locking component 5 enters the locked state and the unlocked state. The specific operation method will be described in detail later, and will not be elaborated here.

[0029] In some embodiments, the connector 3 of the present invention includes two connecting arms 31 and a U-shaped insertion position 32 formed between the two connecting arms 31. The locking hole 30 is formed on the end face of the U-shaped insertion position 32. The connecting arms 31 are used to fix the connector to the terminal block 2 by bolts.

[0030] Furthermore, in this embodiment, the docking seat 4 includes a fixing part 41 and a docking part 42. The docking part 42 is inserted into the U-shaped insertion position 32. Of course, in this embodiment, the fixing part 41 is also fixed to the gateway body 1 by bolts.

[0031] Based on the above embodiments, the locking assembly 5 in this embodiment includes a wedge rod 51. The wedge rod 51 is a rectangular rod with a wedge-shaped structure at its bottom end, so that when the docking seat 4 and the connecting seat 3 are inserted, the wedge rod 51 can move upward and retract by the connecting seat 3 against the wedge-shaped structure. At least one stepped hole 43 is provided on the end face of the docking part 42. The wedge rod 51 is slidably connected in the stepped hole 43, and its bottom end extends through to the bottom of the docking part 42. The bottom end of the wedge rod 51 is inserted into the locking hole 30.

[0032] Furthermore, in this embodiment, the locking assembly 5 also includes a stop cap 52 threadedly connected to the opening of the stepped hole 43. The top end of the wedge rod 51 is formed with a stop platform 53. A spring 54 is placed between the stop cap 52 and the stop platform 53. Preferably, in order to facilitate the disassembly and assembly of the stop cap 52, a slot or cross slot is provided on the upper side of the stop cap 52 in this embodiment. With the design of the slot or cross slot, the stop cap 52 can be disassembled and assembled with the help of tools.

[0033] Specifically, in this embodiment, the detachable design of the stop cap 52 allows for convenient disassembly and maintenance of the wedge rod 51 and the spring 54. During installation, the wedge rod is first inserted into the stepped hole 43, then the spring 54 and the stop cap 52 are inserted in sequence, and finally the stop cap 52 is locked in place by thread.

[0034] In some embodiments, the positioning component 6 of the present invention includes a positioning plate 61, and the front end of the docking part 42 is provided with a slot communicating with the stepped hole 43. The positioning plate 61 is slidably connected in the slot, wherein the front end of the wedge rod 51 has a positioning groove 55 that is inserted into the positioning plate 61.

[0035] Of course, in order to achieve convenient sliding control of the positioning plate 61, the upper end of the docking part 42 in this embodiment is provided with a sliding groove 44 that connects to the slot. The top of the positioning plate 61 is fixedly installed with a toggle post 62 that slides in the sliding groove 44. The inner wall of the sliding groove 44 is formed with a locking protrusion 45 that stops the toggle post 62. The upper end of the docking part 42 is provided with a deformation groove 46 located on the side of the locking protrusion 45. The depth of the deformation groove 46 is the same as the depth of the sliding groove 44. Specifically, the docking part 42 in this embodiment is made of plastic. Through the design of the deformation groove 46, the locking protrusion 45 has a certain deformability. In this way, when the above-mentioned toggle post 62 is slid, the front and rear positions of the toggle post 62 can be locked by the two locking protrusions 45.

[0036] In practical use, when it is necessary to repeatedly insert and remove the terminal block 2, you can touch the wedge rod 51 upward with your finger to move it upward. At this time, you can slide the aforementioned toggle post 62 to move it inward until the side of the positioning plate 61 is engaged in the positioning groove 55 at the end of the wedge rod 51. At this time, the wedge rod 51 is in a locked state and its position remains fixed. Therefore, when the terminal block 2 is in the insertion port 10, the connector 3 and the mating seat 4 can be freely inserted and removed without locking.

[0037] When it is necessary to lock and fix the terminal block 2, the aforementioned actuating post 62 can be moved backward until the actuating post 62 abuts against the side of the stop protrusion 45 on the rear side. At this time, the positioning plate 61 and the positioning groove 55 at the end of the wedge rod 51 are separated, and the wedge rod 51 is in the unlocked state. When the terminal block 2 and the port 10 are connected, the connecting seat 3 will first abut against the wedge rod 51 and move upward during the insertion process until the wedge rod 51 rebounds and is locked in the locking hole 30. In this way, the locking connection of the terminal block 2 can be completed to achieve the purpose of preventing it from falling off.

[0038] In summary, this utility model achieves the purpose of preventing the terminal block 2 from detaching by installing a connector 3 and a docking seat 4 on the terminal block 2 and the gateway body 1 respectively, and by using the locking component 5 on the docking seat 4 to achieve a locking connection with the connector 3.

[0039] In addition, this utility model also provides a positioning component 6 for controlling the locking component 5. The positioning component 6 can keep the locking component 5 in a locked state and an unlocked state. For example, during installation, inspection and maintenance, the positioning component 6 can keep the locking component 5 in a locked state. At this time, the locking component 5 cannot lock the connector 3. Therefore, in this state, the reciprocating insertion and removal operation of the terminal block 2 and the port 10 is supported, thus further improving the applicability of the gateway.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
