Description

Technical Field

[0001] This utility model relates to the technical field of anti-crosstalk concentrators, and in particular to an anti-crosstalk concentrator. Background Technology

[0002] In fields such as smart grids, industrial automation, and the Internet of Things, with the surge in the number of terminal devices, the density of data acquisition and transmission is growing exponentially. As the core device of the data acquisition system, the concentrator is responsible for aggregating multiple signals and uploading them to the main station. Its performance directly affects the reliability and efficiency of the system. With the dense deployment of terminal devices, the concentrator needs to operate in a complex electromagnetic environment for a long time, facing challenges such as signal crosstalk, equipment aging, and frequent failures. At the same time, the ease of on-site maintenance directly affects system downtime and operation and maintenance costs. Therefore, developing a concentrator that is easy to start and maintain and has efficient anti-crosstalk capabilities has become a core requirement for improving system reliability and reducing the cost of full life cycle management.

[0003] Currently, existing anti-crosstalk concentrators use an integrated shell and sealed structure to improve the protection level, which makes it difficult for personnel to open and maintain them, and makes the operation more difficult during installation, thus reducing the convenience of use. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an anti-crosstalk concentrator that improves the convenience of inspection and maintenance of electrical components inside the housing, reduces installation difficulty, improves loading and unloading efficiency, and enhances ease of use.

[0005] This utility model discloses an anti-crosstalk concentrator, comprising a housing and a cover. The cover is installed at the top opening of the housing and has a display screen and operation buttons. The circuit components of the anti-crosstalk concentrator are housed inside the housing. It also includes a pushing device, a fixing device, multiple sets of connectors, multiple sets of slots, and multiple sets of positioning grooves. The multiple sets of connectors are all installed on the bottom of the inner side wall of the cover, and the multiple sets of positioning grooves are respectively disposed on the multiple sets of connectors. The housing has a pushing device, and the multiple sets of slots are all mounted on the pushing device. The pushing device provides pushing force to the slots, and the front end of the slot extends into the positioning groove. The fixing device is disposed between the housing and the cover. The device is used to fix the housing and the cover. When the cover needs to be disassembled, the fixing device is first disassembled, and then the slot is moved by operating the pushing device to separate the slot from the positioning groove, which facilitates the disassembly of the housing and the cover and improves the convenience of inspection and maintenance of the electrical components inside the housing. When the cover is installed, the cover moves the connecting piece downward to push the slot to move. When the positioning groove moves to the side of the slot, the slot is inserted into the positioning groove by the power of the pushing device, thereby pre-fixing the housing and the cover, reducing the installation difficulty, improving the loading and unloading efficiency, and improving the ease of use of the anti-crosstalk concentrator.

[0006] Preferably, the pushing device includes a cylinder, a positioning plate, a limiting plate, a spring, and a metal block. Multiple sets of cylinders are installed on the inner sidewall of the housing. Multiple sets of positioning plates are fixedly installed inside the multiple sets of cylinders. Multiple sets of slots are slidably installed on the multiple sets of positioning plates and multiple sets of cylinders. Multiple sets of limiting plates are installed on the outer sidewall of the multiple sets of slots. Multiple sets of springs are fitted onto the outer sidewall of the multiple sets of slots. Multiple sets of metal blocks are installed at the rear end of the multiple sets of slots. When the cover needs to be removed, a magnet is placed on the side of the metal block outside the housing, so that the magnetic force of the magnet drives the metal block to move. After the metal block moves, it pulls the slot backward, thereby separating the slot from the positioning groove, improving the convenience of cover removal. When the cover is installed on the housing, the spring provides elastic push to the slot, thereby improving the convenience of the slot automatically inserting into the positioning groove, while improving the anti-arbitrary opening effect of the cover and improving the safety of use.

[0007] Preferably, it also includes a filter, a bracket, a fan, and an exhaust port. An air inlet is provided at the bottom of the housing, the filter is located at the air inlet, the bracket is installed on the inner side wall of the housing, the fan is installed on the bracket, and the exhaust port is located on the upper part of the outer side wall of the housing. By turning on the fan, outdoor air is drawn into the housing, and the air inside the housing is discharged through the exhaust port, thereby allowing airflow to dissipate heat and cool the inside of the housing, reducing high-temperature failures of the anti-crosstalk concentrator. The filter filters the air, reducing the entry of dust and dirt into the housing and improving the protection effect.

[0008] Preferably, it also includes a bevel and a hemisphere, with the bevel located at the bottom of the connector and the hemisphere located at the front of the slot; when the cover is installed on the housing, the cover drives the connector to move and contact the slot, and the cooperation between the bevel and the hemisphere improves the convenience of the connector pushing the slot to retract and improves the ease of operation.

[0009] Preferably, the fixing device includes multiple sets of internal threaded parts and multiple sets of screws. The multiple sets of internal threaded parts are all disposed on the outer side wall of the housing, and the multiple sets of screws pass through the cover and are installed on the multiple sets of internal threaded parts. After the cover is pre-fixed to the top of the housing, the multiple sets of screws pass through the cover and are installed on the multiple sets of internal threaded parts, thereby making the housing and the cover reliably connected.

[0010] Preferably, it also includes multiple sets of positioning elements, all of which are set on the outer side wall of the housing; by setting multiple sets of positioning elements, the convenience of housing installation and use is improved.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the cover needs to be disassembled, the fixing device is first disassembled, and then the slot is moved by operating the pushing device to separate the slot from the positioning groove, thereby facilitating the disassembly of the housing and the cover and improving the convenience of inspection and maintenance of the electrical components inside the housing. When the cover is installed, the cover moves the connecting piece downward to push the slot to move. When the positioning groove moves to the side of the slot, the slot is inserted into the positioning groove by the power of the pushing device, thereby pre-fixing the housing and the cover, reducing the installation difficulty, improving the loading and unloading efficiency, and improving the ease of use of the anti-crosstalk concentrator.
