Technical Field
[0001] This utility model relates to the field of temperature sensor technology, specifically a ribbon cable type multi-channel temperature sensor. Background Technology
[0002] A wired multichannel temperature sensor is a sensor device capable of simultaneously measuring the temperature of multiple channels. It connects multiple temperature sensing elements via a wired connection to achieve synchronous monitoring of the temperature at different locations or areas. This type of sensor typically uses resistive temperature detectors or thermocouples and features high precision, fast response, and multi-point measurement. It is widely used in industrial automation, environmental monitoring, and automotive exhaust monitoring. For example, in automotive exhaust emission systems, it can monitor the exhaust temperature at different locations in real time, providing accurate data to the engine control unit to optimize fuel consumption and protect sensitive components.
[0003] In a ribbon cable multichannel temperature sensor, the use of the ribbon cable is to achieve centralized management of signals from multiple sensors. Specifically, the ribbon cable is connected to the signal lines of the sensors, and the signal line of each sensor is connected to one line in the ribbon cable. This design allows the signals from multiple sensors to be transmitted to the signal line interface through a single ribbon cable, simplifying the wiring process, reducing installation complexity, and improving measurement efficiency and accuracy. In addition, when the sensor is a four-wire or five-wire sensor, the common point lines of n sensors can be connected to the same common point main line, which is connected to the positive or negative terminal of the power supply.
[0004] When using traditional wiring methods, the wiring of each sensor is done independently, which leads to a significant increase in the amount of wiring and is quite cumbersome in the process of wiring and fixing the sensors, requiring a lot of time and effort. In addition, this method is also prone to wiring mess and increases the risk of errors.
[0005] In view of this, we propose a ribbon cable multichannel temperature sensor. Utility Model Content

[0030] When using traditional wiring methods, the wiring of each sensor is done independently, which leads to a significant increase in the amount of wiring and is quite cumbersome in the process of wiring and fixing the sensors, requiring a lot of time and effort. In addition, this method is also prone to wiring chaos, increasing the risk of errors.
[0031] like Figures 3-7As shown, this embodiment provides a ribbon cable type multi-channel temperature sensor, including a temperature sensor body 1, a common terminal 2, and a slot 3. A ribbon cable crimping assembly 5 is inserted into the inner side of the slot 3. An operating component 4 is fixedly connected to the top of the ribbon cable crimping assembly 5. A circuit connection wire 6 is crimped and fixed inside the ribbon cable crimping assembly 5. The circuit connection wire 6 is crimped and fixed inside the ribbon cable assembly 7. The ribbon cable crimping assembly 5 includes a fixing base 51. A guide hole 52 is opened at the upper end of the fixing base 51. A movable crimping groove 53 is opened inside the fixing base 51. A limit telescopic rod 54 is fixedly connected to the upper end of the movable crimping groove 53. A pressure plate 55 is fixedly connected to the bottom end of the limit telescopic rod 54. A first rubber sleeve 56 is fixedly connected to the lower end of the pressure plate 55. A second rubber sleeve 57 is fixedly connected to the inner side of the movable crimping groove 53. A metal pad 58 and a plug 59 are fixedly connected to the rear end of the movable crimping groove 53. The circuit connection wire 6 is crimped and fixed inside the movable crimping groove 53. During installation, the temperature sensor body 1 is first fixed to the common terminal 2. The insulation on both ends of the circuit connection wire 6 is stripped. By rotating the screw 43 of the operating component 4, the extension block 45, guide post 46, and pressure plate 55 move upward. The guide post 46 slides and is limited within the guide hole 52. The limiting telescopic rod 54 retracts to stabilize the pressure plate 55, moving it away from the metal pad 58. Space is left between the first rubber sleeve 56 and the second rubber sleeve 57. As needed, serial numbers are set on the common terminal 2 and the operating component 4. The circuit connection wire 6 is inserted into the movable crimping groove 53, with the front end passing through the rubber sleeve to the upper end of the metal pad 58. The operation is repeated to complete the installation of all circuits. Then, the front end of the circuit connection wire 6 is inserted into the ribbon cable assembly 7. Finally, the operation is reversed to fix the circuit. The ribbon cable assembly 7 is then inserted into the controller to complete the installation. The device simplifies wiring and reduces workload and error rate by centrally managing the circuit connection wire 6. The design of the limiting telescopic rod 54 and the rubber sleeve improves the stability of the circuit fixation. The serial number marking reduces the wiring error rate and improves installation efficiency and reliability. The overall structure is reasonable, highly adaptable, and extends service life.
[0032] like Figure 4 As shown, the operating component 4 includes an upper cover plate 41. A limiting shaft hole 42 is opened on the inner side of the upper cover plate 41. A screw 43 is rotatably connected to the inner side of the limiting shaft hole 42. A screw hole 44 is screwed to the outer side of the screw 43. The screw hole 44 is opened on the inner side of the extension block 45. The bottom end of the upper cover plate 41 is fixedly connected to the top end of the fixed seat 51. A guide post 46 is fixedly connected to the bottom end of the screw hole 44. A gap is provided between the bottom end of the extension block 45 and the top end of the fixed seat 51. The guide post 46 slides inside the guide hole 52. The bottom end of the guide post 46 is fixedly connected to the top end of the pressure plate 55. Through the above configuration, this structural design allows the guide post 46 to slide more smoothly inside the guide hole 52. At the same time, the fixed connection between the guide post 46 and the pressure plate 55 can effectively transmit power, ensuring the stability and reliability of the device during operation, avoiding failures caused by loosening between components, and improving the service life and operating efficiency of the device.
[0033] like Figures 6-7 As shown, the front end of the temperature sensor body 1 is crimped and fixed to the common terminal 2. The operating component 4 and the cable crimping component 5 are both inserted into the slot 3. The metal pad 58 and the insert 59 are electrically connected. The common terminal 2 is provided with multiple connecting lines. The insert 59 is electrically connected to the temperature sensor body 1 through a single connecting line inside the common terminal 2. Through the above settings, a tight connection between the sensor and the connecting components can be ensured, avoiding measurement errors caused by poor contact. At the same time, the design of multiple connecting lines can meet the signal transmission requirements of multiple sensors, improve the applicability and flexibility of the device, and provide strong support for realizing multi-channel temperature measurement.
[0034] like Figure 3 and Figure 7 As shown, the structure of the ribbon cable assembly 7 is the same as the sum of the structures of the operating assembly 4 and the ribbon cable crimping assembly 5. Both ends of the circuit connection line 6 have exposed metal wires. The metal wires of the circuit connection line 6 are crimped between the metal pad 58 and the pressure plate 55. The pressure plate 55 is slidably connected inside the movable crimping groove 53. A gap is provided between the top of the pressure plate 55 and the top of the movable crimping groove 53. The number of movable crimping grooves 53 is the same as the number of pressure plates 55. Through the above settings, it can be ensured that the signal of each sensor can be effectively managed and transmitted, thereby improving the multi-channel measurement capability of the device.
[0035] like Figure 3 and Figure 7 As shown, the top of the second rubber sleeve 57 is fitted with the bottom of the first rubber sleeve 56, and an arc-shaped block is fixed at the lower end of the movable pressing groove 53. The outer side of the circuit connection line 6 is fitted with the inner side of the first rubber sleeve 56 and the inner side of the second rubber sleeve 57. Through the above settings, not only is the assembly accuracy and stability of the device improved, but the loosening and detachment of the circuit connection line 6 during use can also be effectively prevented, further improving the reliability and durability of the device and providing a guarantee for achieving efficient and stable temperature measurement.
[0036] In summary, the working principle of this solution is as follows: When wiring and installing the temperature sensor body 1, firstly, according to the required number of temperature sensor bodies 1, fix the temperature sensor body 1 on the common terminal 2. Then, run the circuit connection wire 6, remove the insulation from both ends of the circuit connection wire 6, and turn the screw 43 with a screwdriver. When the screw 43 turns, it drives the extension block 45, guide post 46, and multiple pressure plates 55 to move upward through the screw hole 44. The guide post 46 slides inside the guide hole 52, which limits the upward movement of the extension block 45. When the pressure plate 55 moves upward, the limiting telescopic rod 54 retracts, which can improve the stability of the pressure plate 55 during movement. At this time, the pressure plate 55 is far away from the metal pad 58, and there is space between the first rubber sleeve 56 and the second rubber sleeve 57. Then, according to the position of the temperature sensor body 1, insert the circuit connection wire 6 into the designated movable crimping groove 53. As needed, the corresponding crimping end on the upper end of the common terminal 2 and the operation... The crimping sections corresponding to component 4 are assigned serial numbers, which reduces the error rate of wiring the circuit connection wire 6. The front end of the circuit connection wire 6 is inserted between the first rubber sleeve 56 and the second rubber sleeve 57 until the metal wire of the circuit connection wire 6 is on the upper end of the metal pad 58. The other circuit connection wires 6 are installed in the same way. After completion, the front end of the circuit connection wire 6 is installed into the inside of the ribbon cable assembly 7. After the front and rear ends of the circuit connection wire 6 are installed, the circuit connection wire 6 is fixed. The screw 43 is rotated according to the above principle, causing the pressure plate 55 to move downward. The setting of the first rubber sleeve 56 and the second rubber sleeve 57 can improve the stability of fixing the circuit connection wire 6. The cooperation between the pressure plate 55 and the metal pad 58 can fix the metal wire end of the circuit connection wire 6. Then the ribbon cable assembly 7 is plugged into the existing controller to complete the wiring and installation. Based on the above principles, the device can concentrate the wiring of the sensors, improve the wiring efficiency, reduce the labor intensity of the workers, and reduce the wiring error rate.
[0037] 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.
