Description

Technical Field

[0001] This utility model relates to the field of wireless data transmission technology, and in particular to a GPRS signal conversion connection device. Background Technology

[0002] GPRS DTU, or Data Transmission Unit, is a wireless data terminal for the Internet of Things (IoT). It can convert serial port data into GPRS signals for transmission, and it can also convert received GPRS signals into serial port data for output. It is a GPRS signal conversion device with more complex functions and higher integration.

[0003] Most current GPRS DTU modules adopt a box-type design, with power terminals on the top and RS232 / 485 / 422 terminals on the bottom. These terminals are exposed for extended periods when not connected, offering insufficient protection. Furthermore, GPRS DTU modules are typically fixed in place using wall-mounted plates at both ends. This method requires repeatedly removing the wall-mounted plates for subsequent maintenance and repair, resulting in low efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a GPRS signal conversion connection cable device. This invention allows for the pre-mounting of the docking seat in a designated location during installation. The docking seat is then connected to the GPRS signal conversion host, and the two are secured by a limiting component. This design eliminates the need to repeatedly remove the wall-mounted mounting plate during subsequent disassembly and maintenance of the GPRS signal conversion host, simplifying operation. Furthermore, when no wiring is required, a sealing plate can be inserted into the protective cover to protect the upper and lower terminals.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A GPRS signal conversion connector includes: a GPRS signal conversion connector main unit and a docking station. The upper and lower ends of the GPRS signal conversion connector main unit are integrally connected with protective covers. Each protective cover has an opening that can be closed by inserting a sealing plate. Each protective cover has an integrally connected docking block on its rear side. Each docking block is inserted into two docking slots at the front end of the docking station. Each of the upper and lower ends of the docking station is provided with a limiting component to fix the docking block in the docking slot.

[0007] The present invention is further configured such that each of the protective covers has an insertion port at the front end, and each of the sealing plates is inserted into the interior of the protective cover through the insertion port.

[0008] The present invention is further configured such that limit holes are provided through the surface of the docking blocks.

[0009] The present invention is further configured as a limiting component comprising: two springs connected to the upper and lower ends of the docking seat; a pull plate fixed to the other end of the two springs; and a limiting post connected to the middle of the pull plate and located between the two springs.

[0010] The present invention is further configured such that the limiting post can pass through the surface of the docking seat into the docking groove.

[0011] The present invention is further configured such that the back of the docking seat is connected to two wall-mounted mounting plates, and each wall-mounted mounting plate has two mounting holes on its surface.

[0012] The present invention is further configured such that the GPRS signal conversion wiring host is provided with terminals at both the top and bottom, and the GPRS signal conversion wiring host is provided with an antenna interface at the bottom.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The GPRS signal conversion cable device has a protective cover integrated at both the top and bottom of the GPRS signal conversion cable host. When not connected, a sealing plate can be inserted from the front socket of the protective cover to close the opening of the protective cover, so that the top and bottom terminals of the GPRS signal conversion cable host will not be exposed to the outside for a long time, thus effectively protecting the terminals.

[0015] 2. When installing this GPRS signal conversion connection cable device, the docking seat can be pre-fixed in the designated position by the wall-mounted mounting plate. Then, the docking block on the back of the protective cover is inserted into the docking groove in front of the docking seat, and the docking block is fixed in the docking groove by the limiting components at the upper and lower ends of the docking seat. This design replaces the method of directly fixing the designated position by the wall-mounted mounting plate. In subsequent disassembly and maintenance, there is no need to repeatedly disassemble the wall-mounted mounting plate, which improves maintenance efficiency. Attached Figure Description

Therefore, they should not be construed as limitations on this patent.

[0025] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0026] Reference Figure 1-5 A GPRS signal conversion connection device includes: a GPRS signal conversion connection host 1, which is a GPRS STU module, which can install a SIM card and connect to a serial cable, a power cable, and an antenna for connection and data communication with external devices.

[0027] Traditional GPRSDTU modules, such as Figure 2As shown, the power terminal 4 is located above the GPRS signal conversion wiring host 1, the serial port terminal 4 is located below the GPRS signal conversion wiring host 1, and the antenna interface 5 is located below. During installation, the GPRS signal conversion wiring host 1 is fixed in the designated position by the wall mounting plates 6 at both ends, and the positioning screws are connected into the mounting holes 9 of the wall mounting plates 6.

[0028] In this embodiment, it can be referred to Figure 1 A protective cover 2 is integrally connected to the upper and lower ends of the GPRS signal conversion wiring host 1. The protective cover 2 is hollow and has openings on its surface to facilitate wiring of the GPRS signal conversion wiring host 1.

[0029] For details, please refer to Figure 5 When the device is not connected, a sealing plate 15 can be inserted into the socket 14 in front of the protective cover 2. The sealing plate 15 can close the exposed opening of the protective cover 2, thereby protecting the terminals 4 at the top and bottom of the GPRS signal conversion wiring host 1 and improving the protection performance of the device.

[0030] In this embodiment, as Figure 3 As shown, a docking block 7 is integrally connected to the back of the protective cover 2, and a limiting hole 8 is opened on the surface of the docking block 7.

[0031] In this embodiment, as Figure 3 As shown, a docking seat 3 is added, and two wall-mounted mounting plates 6 are integrally connected to the back of the docking seat 3. The docking seat 3 is pre-fixed in the designated position by the two wall-mounted mounting plates 6.

[0032] Specifically, such as Figure 4 As shown, the front end of the docking seat 3 has two docking slots 10, and two docking blocks 7 can be inserted into the two docking slots 10 respectively. At the same time, limit components are provided at the upper and lower ends of the docking seat 3, and the limit components can fix the docking blocks 7 in the docking slots 10.

[0033] Furthermore, the limiting assembly includes a limiting post 11, a pull plate 12, and a spring 13. The spring 13 is fixed to the surface of the docking seat 3, and the other end of the pull plate 12 and the spring 13 are fixed. The limiting post 11 is fixed to the pull plate 12.

[0034] Furthermore, when installing the GPRS signal conversion wiring host 1 and the docking seat 3: first, pull up the upper and lower pull plates 12 so that the limiting posts 11 are disengaged from the docking slots 10. Then, insert the docking blocks 7 on the back of the protective cover 2 into the two docking slots 10 respectively. Then, release the upper and lower pull plates 12. The spring force of the spring 13 will push the limiting posts 11 back into the docking slots 10, and then insert them into the limiting holes 8 on the surface of the docking blocks 7 respectively, thus completing the locking of the docking blocks 7.

[0035] Compared to traditional installation methods, which involve fixing the device to a designated position using a wall-mounted mounting plate 6, this design eliminates the need to disassemble the wall-mounted mounting plate 6 again during subsequent maintenance of the GPRS signal conversion wiring host 1. Instead, the locking of the docking block 7 can be released simply by using the limit component, thus improving maintenance efficiency.

[0036] Working principle: When using this utility model, the GPRS signal conversion connector is integrally connected to the upper and lower ends of the GPRS signal conversion connector 1 with a protective cover 2. In the unconnected state, the sealing plate 15 can be inserted into the front socket 14 of the protective cover 2 to close the opening of the protective cover 2, thereby preventing the upper and lower terminals 4 of the GPRS signal conversion connector 1 from being exposed for a long time, effectively protecting the terminals 4. During installation, the docking seat 3 can be pre-fixed in the designated position by the wall mounting plate 6, and then the upper part can be pulled up. The lower pull plate 12 causes the limiting posts 11 to disengage from the docking groove 10. Then, the docking blocks 7 on the back of the protective cover 2 are inserted into the two docking grooves 10. Then, the upper and lower pull plates 12 are released, and the limiting posts 11 are reinserted into the docking grooves 10 by the rebound force of the spring 13. They are then inserted into the limiting holes 8 on the surface of the docking blocks 7, thus locking the docking blocks 7. This design replaces the method of directly fixing the designated position by the wall-mounted mounting plate 6. In subsequent disassembly and maintenance, it is not necessary to repeatedly disassemble the wall-mounted mounting plate 6, thus improving maintenance efficiency.

[0037] 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.
