Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A multipoint temperature detecting sensor, see fig. 1, wherein (1) is a multi-core cable, the number of cores of the multi-core cable is an integer greater than 1, and is related to the number of connected temperature sensors; the core can be made of copper wire, but is not limited to the copper wire; in the figure, (2) is a protective layer; the temperature sensor includes but is not limited to a thermistor, a platinum resistor, etc., and is not particularly limited herein; the magnetic attraction and the movable buckle are used for fixing the multi-core cable at a specific position, such as a cabinet of a machine room or other equipment to be measured in temperature. The multi-core cable is used for connecting the plurality of temperature sensors and transmitting a temperature signal detected by the temperature sensors to the data acquisition end at the rear end through the output port; the number of cores and the connection mode of the multi-core cable determine the number of temperature test points which can be provided on the cable.
Taking the example that the temperature sensor adopts a thermistor, the thermistor has two pins, and then the multi-core cable can adopt cables with a plurality of cores (such as 8-core cables, 12-core cables and the like), and the multi-core cable can be connected with four thermistors to form a multi-point temperature detection sensor with four temperature detection points. It can be understood that if more test points are needed, cables with more wire cores can be adopted in the same way to connect more thermistors to form a multipoint temperature detection sensor meeting the actual requirement, so that the problem that the test points of the traditional temperature sensor are single is solved.
Meanwhile, the outer layer of the temperature sensor is wrapped with a protective layer formed by injection molding, as shown in fig. 2. Wherein, (1) is the protective layer of injection moulding, (2) is multicore cable. In the production process, the temperature sensor is directly injection-molded on the multi-core cable, so that after injection molding, a protective layer is formed on the outer layer of the temperature sensor to play a role in protection; compared with the traditional pouring sealant filling and sealing mode, the processing mode of injection molding is simpler, the processing time is shortened, and the production efficiency is greatly improved.
Further, in an embodiment, the protection layer is formed by encapsulation and molding of a stainless steel sleeve, and based on the heat conduction characteristic of the stainless steel sleeve, one-line multi-point temperature detection can be performed in a suitable application scene.
Further, in an embodiment, the temperature sensors are connected in a line-and-point manner, and the multi-core cable is connected in a segmented manner, that is, the multi-core cable is not one but divided into a plurality of segments, and one temperature sensor is connected to each segment of cable, so that the temperature sensors can be spliced in segments, and the length of the whole multi-point temperature detection sensor can be flexibly adjusted as long as the line sequence of each segment is ensured to correspond, thereby being suitable for complex and variable test environments.
Further, in an embodiment, a PCB is disposed between the temperature sensor and the multi-core cable, the temperature sensor is soldered on the PCB, and the multi-core cable is soldered on the PCB according to a predetermined sequence. Taking a thermistor with a temperature sensor as a patch type as an example, taking a PCB as a connecting channel of the thermistor and a multi-core cable, on one hand, the thermistor is directly welded on the PCB, and on the other hand, the multi-core cable is welded on the PCB according to a preset wire sequence, so that a temperature signal detected by the thermistor reaches the multi-core cable through the PCB and is finally transmitted to a data acquisition end at the rear end. The PCB bridging mode is adopted, so that the reliability of connection between the thermistor and the multi-core cable can be improved.
The preset wire sequence refers to the corresponding connection of the wire cores of the multi-core cable and the pins of the temperature sensor according to a predefined connection sequence. Taking a multi-core cable as a 4-core wire and a temperature sensor as two 2-pin thermistors as an example, pins 1 and 2 of the thermistor NTC1 are respectively connected with an orange wire and an orange-white wire; pins 1 and 2 of the thermistor NTC2 are respectively connected with a blue line and a blue-white line. If the connection is wrong, the resistance value will be increased or decreased, so that the detected temperature value is inaccurate. The multi-core cable is welded on the PCB according to a preset wire sequence, so that the temperature detection precision can be ensured.
Further, in an embodiment, the output port adopts a network cable crystal head or a cold-pressed terminal, and a uniform data interface is provided for the outside, so that data can be transmitted to the data acquisition end at the rear end conveniently.
Further, in one embodiment, the multi-core cable is provided with a magnetic attraction fixed by a double-wall heat-shrinkable sleeve. The magnetic attraction can be arranged at any position on the multi-core cable, a double-wall heat-shrinkable sleeve is sleeved outside the magnetic attraction, and the double-wall heat-shrinkable sleeve is used for fixing the magnetic attraction on the multi-core cable. The multi-core cable provided with the magnetic attraction can be conveniently adsorbed and fixed on a cabinet of a machine room, so that the temperature of the cabinet can be detected; or the magnetic attraction is mutually adsorbed, so that the temperature sensors are centralized, and the temperature test of the densely distributed points to be detected is facilitated.
Further, in an embodiment, a plurality of movable buckles are further arranged on the multi-core cable, so that a fixing mode of the multi-core cable different from the magnetic attraction mode is realized, and the multi-core cable can adapt to more application scenes.
It is right above the utility model discloses multiple spot temperature detection sensor has explained for help understands the utility model discloses, nevertheless the utility model discloses an embodiment does not receive the restriction of above-mentioned embodiment, and any does not deviate from the utility model discloses change, modification, substitution, combination, simplification made under the principle all should be equivalent replacement mode, all contain within the protection scope the utility model discloses a.
