Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically to a terminal block device with integrated current detection function. Background Technology

[0002] In the field of electrical equipment, terminal blocks, as key components for power and signal transmission, are widely used in various equipment cabinets to connect wire harnesses and realize circuit conduction and electrical connection. With the continuous improvement of the intelligence and automation of electrical equipment, the functional requirements of terminal blocks are also getting higher and higher. They not only need to have reliable electrical connection performance, but also need to be able to detect the current in the wire harness in real time so as to understand the operating status of the equipment in a timely manner and prevent the occurrence of faults.

[0003] However, existing terminal block devices have some shortcomings in practical applications. The performance of existing terminal block devices in terms of protection and heat dissipation needs to be improved. In some harsh working environments, dust, debris and moisture can easily enter the device, causing short circuits or damage to the terminal block and affecting the normal operation of the equipment. At the same time, if the heat generated by the current during the operation of the terminal block cannot be dissipated in time, the internal temperature of the device will rise, thereby affecting the working performance and service life of the terminal block.

[0004] In addition, existing terminal block devices also have inconveniences in fixing wire harnesses. The fixing of wire harnesses inside the device is not stable enough and they are prone to movement due to vibration and other factors. This not only affects the stability of the circuit connection, but also leads to a decrease in the accuracy of current detection. Existing terminal block devices also have shortcomings in terms of observation and maintenance. Operators cannot intuitively observe the working status inside the device, which is not convenient for equipment debugging, maintenance and troubleshooting, and increases the maintenance cost and time of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a terminal block device with integrated current detection function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a back plate and a terminal block. The terminal block is fixed to the front surface of the back plate. Detection grooves are fixed to both the upper and lower ends of the terminal block. Multiple sliding members are slidably connected inside each detection groove. A driving member is fixed to one side of each sliding member. A driving member is rotatably connected to the side of the driving member away from the sliding member. A fixing head is fixed to the side of the driving member close to the sliding member. A protective shell is fixed to the front surface of the back plate. A viewing cover is attached to the front surface of the protective shell. Insertion members are fixed to both the upper and lower ends of the viewing cover. A fixing member is fixed inside each insertion member.

[0007] Preferably, the connector includes a fixing block, which is fixedly connected to one end of the visible cover plate. The outer wall of the fixing block is fitted with a fixing slot, which is fixedly connected to the protective shell.

[0008] Preferably, the fastener includes an elastic element, which is fixedly connected to the inner wall of the fixing slot, and a snap-fit ​​element is fixed to one end of the elastic element.

[0009] Preferably, the visible cover is made of polymethyl methacrylate, which has a certain degree of elasticity and bending resistance, is not easily brittle, and has excellent transparency.

[0010] Preferably, fans are provided on both the left and right sides of the protective housing, with one side fan being an intake fan and the other side fan being an exhaust fan, and the fans can provide stable heat dissipation for the terminal block.

[0011] Preferably, a Hall sensor is fixed on one side of each wire harness inside the detection slot, and the Hall sensor is used to detect the current of the wire harness.

[0012] Preferably, the inner wall of the detection groove is provided with a plurality of "T"-shaped sliding grooves, which are matched with the sliding member for sliding inside.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Flexible detection and adjustment mechanism: The "T"-shaped groove on the inner wall of the detection tank matches the sliding component. The operator can rotate the driving component by external force, which will move the driving component and the fixed head, thereby realizing flexible adjustment of the position of the fixed head. This design enables the device to adapt to the fixing and detection needs of wire harnesses in different positions, improving the applicability and operability of the device.

[0014] A stable wiring harness fixing method: The fixing head is fixed to the drive component. By fixing the wire harness, the position of the wire harness in the detection slot is ensured to be stable. This fixing method effectively avoids the movement of the wire harness caused by factors such as vibration. It not only ensures the stability of the circuit connection, but also keeps the Hall sensor in close contact with the wire harness at all times, thus improving the accuracy of current detection.

[0015] Protection and heat dissipation: The protective housing encloses the terminal blocks, detection slots, and other components, providing excellent dust and moisture protection. This prevents dust and debris from entering the interior and avoids short circuits or damage to the terminal blocks caused by moisture, thus extending the service life of the device. At the same time, the intake and exhaust fans on the left and right sides of the protective housing create airflow, which can promptly remove the heat generated by the terminal blocks during operation, providing stable heat dissipation for the terminal blocks and ensuring that they operate in a suitable temperature environment, thereby improving the reliability and stability of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a terminal block device with integrated current detection function: it includes a back plate 1 and a terminal block 2. The back plate 1 serves as the basic support structure of the entire device and is fixedly installed on the equipment cabinet or other mounting surface, providing a stable mounting foundation for components such as the terminal block 2, the detection slot 3, and the protective shell 8. The terminal block 2 is fixed on the front surface of the back plate 1. The terminal block 2 is a key component for power and signal transmission. It consists of multiple terminal units and is used to connect wire harnesses to realize circuit conduction and electrical connection. During the current detection process, the sensing end of the Hall sensor inside the detection slot 3 comes into close contact with the wire harness to perform current detection.

[0020] Both ends of the terminal block 2 are fixed with detection slots 3. The detection slots 3 are equipped with multiple sliding parts and Hall sensors for detecting current. The inner wall of the detection slots 3 is provided with "T"-shaped sliding grooves that match the sliding parts 4, which provide guidance and support for the sliding of the sliding parts 4. The Hall sensors are fixed on one side of each wire bundle inside the detection slots 3. When current flows through the wire bundle, the Hall sensor will detect the change in magnetic field according to the Hall effect, thereby converting the current signal into an electrical signal and realizing the detection of the current status of the wire bundle.

[0021] Multiple sliding parts 4 are slidably connected inside the detection slot 3. The sliding parts 4 can drive the driving parts 5 to move by sliding. When it is necessary to fix or adjust the wire harness at different positions, the operator can adjust the fixing head 7 by rotating the driving part 6. The driving part 5 is fixed on one side of the sliding part 4. The driving part 5 can drive the fixing head 4 to move up and down under the drive of the driving part 6, thereby adjusting and fixing the wire harness. The driving part 6 is rotatably connected to the side of the driving part 5 away from the sliding part 4. The rotation of the driving part 6 can drive the driving part 5 to move up and down through its own thread.

[0022] A fixing head 7 is fixed on the side of the drive component 5 near the sliding component 4. The fixing head 7 is used to fix the wire harness. The fixing head 7 ensures that the position of the wire harness in the detection slot 3 is stable, and avoids the wire harness from moving due to vibration, which would affect the detection accuracy of the Hall sensor. At the same time, it ensures the stability of the circuit connection. A protective shell 8 is fixed on the front surface of the back plate 1. The protective shell 8 encloses the terminal block 2 and the detection slot 3 and other components, and plays a role in dust and moisture protection, preventing dust and debris from entering the interior. It also prevents the terminal block from short circuits or damage caused by moisture entering. Fans are set on the left and right sides. One fan is an intake fan and the other fan is an exhaust fan. The operation of the fans creates air circulation and provides stable heat dissipation for the terminal block 2, preventing the terminal block from being affected by excessive heat generated by the current during operation, which would affect its normal working performance and service life.

[0023] The front surface of the protective housing 8 is fitted with a viewing cover 9. The viewing cover 9 is made of polymethyl methacrylate, which has good elasticity, bending resistance and excellent transparency. Through the viewing cover 9, the operator can clearly observe the working status and connection of the terminal block 2, detection slot 3 and other components inside the protective housing 8, which is convenient for equipment debugging, maintenance and troubleshooting. At the same time, the viewing cover is connected to the protective housing 8 through plug-in parts and fasteners, which ensures its installation stability and removability, and facilitates operation inside the device.

[0024] Both the upper and lower ends of the visible cover plate 9 are fixed with connectors. The connectors include a fixing block 10, which is fixedly connected to one end of the visible cover plate 9. The fixing block 10 is fitted into the fixing slot 11 on the protective shell 8. When installing the visible cover plate 9, the fixing block 10 is inserted into the fixing slot 11 to achieve the initial positioning and connection between the visible cover plate 9 and the protective shell 8, providing a basis for the subsequent snap-fit ​​of the fasteners. The outer wall of the fixing block 10 is fitted with the fixing slot 11, which is fixedly connected to the protective shell 8.

[0025] A fixing component is fixed inside the fixing slot 11. The fixing component includes an elastic element 12, which is fixedly connected to the inner wall of the fixing slot 11. The elastic element 12 has the ability to elastically deform. When the latching member 13 is subjected to external force, the elastic element 12 will deform and store elastic potential energy. When the external force disappears, the elastic element 12 will return to its original shape and drive the latching member 13 to reset, thereby achieving support and reset of the latching member 13. One end of the elastic element 12 is fixed to the latching member 13, which can move within the fixing slot. When the fixing block is inserted into the fixing slot, the latching member, pushed by the elastic element, latches into the slot or corresponding latching position on the fixing block, achieving a firm connection between the visible cover and the protective shell, preventing the visible cover from falling off during use.

[0026] Working principle: When using a terminal block device with integrated current detection function, the operator first needs to move the driving component 5 and the fixing head 6 to the designated position by rotating the driving component 6. Then, the wire harness is connected to the terminal block 2 through the reserved holes of the protective shell 8 and the detection slot 3. At this time, the fixing blocks 10 on both sides of the visible cover 9 are aligned with the fixing slots 11 and the visible cover 9 is inserted downwards. At this time, because the elastic element 12 inside the fixing slot 11 has the ability of elastic deformation, when the fixing block 10 is inserted downwards, the snap-fit ​​component 13 is subjected to the squeezing force, which causes the elastic element 12 to deform and store elastic potential energy. When the fixing block 10 is inserted into the fixing slot 11, the snap-fit ​​component 13 is pushed by the elastic element 12 and snaps into the corresponding snap-fit ​​position of the fixing block 10. At this time, the visible cover 9 and the protective shell 8 can be firmly connected, preventing the visible cover 9 from falling off during use.

[0027] When it is necessary to remove the viewing cover 9, simply apply a pulling force to pull the viewing cover 9, causing the snap-fit ​​13 to compress the elastic element 12 and disengage from the snap-fit ​​position, thus removing the viewing cover 9. At this time, energize the terminal block 2 and the wire harness. When current flows through the wire harness, the current will generate a magnetic field around the wire, and the Hall sensor can detect the change in this magnetic field. According to the Hall effect, the Hall sensor will output an electrical signal proportional to the magnitude of the current. By processing and analyzing this electrical signal, information such as the magnitude and direction of the current in the wire harness can be obtained, thereby realizing the detection of the current.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
