Description

Technical Field

[0001] This application relates to the field of switch quantity acquisition, and in particular to switch quantity acquisition terminals. Background Technology

[0002] A switch signal acquisition terminal is a device used to acquire and process switch signals, primarily used in industrial automation and the Internet of Things (IoT). Switch signals typically represent "on" and "off" states, similar to a light switch. They can be categorized into active and passive switch signals. The main function of a switch signal acquisition terminal is to acquire and process various switch signals, such as motor switches and valve switches. It converts these switch signals into digital signals through sensors, controllers, and actuators, and then stores and processes them. Switch signal acquisition terminals typically communicate with host computers or cloud programs via RS485 / RS232 / 4G, supporting Modbus RTU protocols and wireless RS485 pass-through functions. These functions enable the terminal to flexibly form local networks and transmit data, supporting wireless communication across multiple frequency bands, further enhancing its flexibility and convenience in practical applications. In conventional switch signal acquisition terminals, connectors are installed at both ends of the terminal body. These connectors are connected to the device to be managed via connecting cables, allowing the terminal body to acquire and manage the device's switch signals.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional switch quantity acquisition terminals are easily affected by humid air when installed in basements or high-humidity environments, especially during spring, autumn, and rainy seasons when high humidity and frequent temperature changes can easily lead to condensation. This can cause moisture to get into the connectors and connecting cables of the switch quantity acquisition terminal, resulting in signal deviations or even short circuits.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

Connectors are fixedly installed at both the top and bottom ends of the acquisition terminal body. The two connecting brackets are symmetrically distributed about the acquisition terminal body, and their cross-sections are "T"-shaped. A shielding bracket is rotatably mounted on the surface of each of the two connecting brackets. The shielding bracket has an "L"-shaped cross-section, and a control block is fixedly connected to one end of each shielding bracket. One end of each connecting bracket engages with the surface of the acquisition terminal body. The two connecting brackets and the two shielding brackets are symmetrically distributed about the acquisition terminal body and the connecting brackets, respectively.

[0008] Preferably, a first spring is fixedly installed between the two control blocks, and one end of the first spring is fixedly connected to the surface of the connecting frame.

[0009] Preferably, one end of the shielding frame is fixedly connected to a fixing frame, the fixing frame is a rubber frame, and the inner wall of the fixing frame is provided with a plurality of connecting grooves, the plurality of connecting grooves being evenly distributed at one end of the fixing frame.

[0010] Preferably, the inner wall of the connecting frame is fitted with two fixing bolts, and the surface of the fixing bolts is threaded to the inner wall of the data acquisition terminal body. The two fixing bolts are symmetrically distributed about the connecting frame.

The plurality of limiting slots are divided into two groups, and the two groups of limiting slots are symmetrically distributed about the fixing block.

[0012] Preferably, the inner wall of the fixed block is slidably connected to two adjusting sliders, a limit frame is fixedly installed between the two adjusting sliders, and the size of the surface of the adjusting sliders is adapted to the size of the inner wall of the fixed block.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By installing a connecting frame on the surface of the connector, two shielding frames are rotatably connected to the surface of the connecting frame. A control block is installed at one end of the shielding frame to shield the connection position between the connector and the connecting cable, preventing external moisture from affecting the position of the connector. A first spring is installed between the two control blocks to keep the shielding frame in contact with the surface of the connector. A rubber fixing frame is installed on the inner wall of each shielding frame. Several connecting grooves are opened on the inner wall of the fixing frame to improve the sealing between the shielding frame and the connecting cable. The inner wall of the connecting frame is threaded with fixing bolts to facilitate the installation of the connecting frame on the surface of the data acquisition terminal. Compared with the existing technology, this method effectively improves the moisture resistance of the switch quantity data acquisition terminal.

[0016] 2. A fixing block can also be installed at the bottom of the connecting frame.

[0027] A fixing block 10 can also be installed at the bottom of the connecting frame 3. The inner wall of the fixing block 10 has several limiting slots 11, so that the fixing block 10 can work with the fixing frame 7 to improve the shielding effect on the connecting line and avoid the problem of the connecting line being damaged by the mutual squeezing of the shielding frame 4 and the acquisition terminal body 1. Two adjusting sliders 13 are slidably connected to the inner wall of the fixing block 10. A limiting frame 12 is installed between the two adjusting sliders 13, so that after the adjusting slider 13 moves on the inner wall of the fixing block 10, the limiting frame 12 can be used to fix the longer connecting line, thereby avoiding the connecting line from being scattered or even knotted, which would affect the use of the acquisition terminal body 1. A second spring 14 is installed on the top of the adjusting slider 13.
