Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, and in particular to a detachable and stable temperature sensor for automotive air conditioning evaporators. Background Technology

[0002] In automotive air conditioning systems, the evaporator is a key component of the refrigeration cycle, and its operating status directly affects the air conditioning's cooling effect. To effectively regulate the air conditioning's cooling performance, a temperature sensor is typically installed on the evaporator. The main function of this sensor is to detect the temperature of the evaporator's surface and transmit the temperature signal to the control system, which in turn controls the compressor's operating status to maintain the evaporator within a suitable temperature range.

[0003] Existing automotive air conditioning evaporator sensors generally meet user needs, but still have certain shortcomings: unstable connections due to the 180-degree straight connection between the temperature sensing component and the wire; direct friction between the end of the temperature sensing component and the connection area with the wire; high replacement costs when components in the adapter are damaged due to difficulty in disassembling and assembling; and damage caused by friction due to relative displacement between the plug and the metal wire inside the wire. These problems prevent such sensors from accurately transmitting the sensed evaporator surface temperature signal to the vehicle's central control system, affecting the normal operation of the vehicle's air conditioning system. Therefore, this invention proposes a detachable and reliably connected temperature sensor for automotive air conditioning evaporators. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a detachable and stable temperature sensor for automotive air conditioning evaporators that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A detachable and stable temperature sensor for automotive air conditioning evaporators includes a temperature sensing component, a wire, a connector, and a wear-resistant and heat-resistant sleeve. The temperature sensing component is connected to one end of the wire, and the other end of the wire is connected to the connector. The wear-resistant and heat-resistant sleeve is fitted over the wire.

[0007] It also includes: a card adapter, which enables the temperature sensing component to be connected to the wire in a straight line at 180° and to be connected at a right angle at 90°.

[0008] The card-changing assembly includes a directional card connector and a plug-in stable connector. The directional card connector is mounted on the side of the plug-in stable connector, the temperature sensing component is mounted on the directional card connector, and the wire connected to the temperature sensing component is laterally mounted on the plug-in stable connector.

[0009] The steering connector allows the connection area between the temperature sensing component and the wire to be changed in direction.

[0010] Preferably, the steering connector has a hollow internal structure, a square connector body at the bottom, a sloping turntable area on the side, and a square hollow connecting part at the top. This square hollow connecting part prevents direct friction between the end of the temperature sensing component and the wire connection area.

[0011] The bottom of the steering buckle is fitted with a plug-in fastener.

[0012] Preferably, a hollow connector is provided on one side of the plug-in connector, the bottom of the plug-in connector is a square shell, the square shell has a groove on the side, the groove matches the size of the square snap-fit ​​body at the bottom of the steering snap-fit, and the hollow connector and the square shell are integrated to form the plug-in connector.

[0013] Preferably, the temperature sensing component includes a temperature sensing chip, epoxy resin, Dummey wire, copper strip, and glass layer. The epoxy resin is mounted on the outside of the temperature sensing chip, the Dummey wire is connected to the temperature sensing chip at one end and connected to the copper strip at the other end, and the glass layer is mounted on the outside of the temperature sensing chip, Dummey wire, and copper strip.

[0014] Preferably, there are two wires, and the outer surfaces of the two wires are wound in a figure-eight shape to prevent mutual friction and relative displacement between the two wires, making it easier to install the wear-resistant and heat-resistant sleeve and less prone to displacement.

[0015] Preferably, the wear-resistant and heat-resistant sleeve can be a glass fiber sleeve, with one end of the wear-resistant and heat-resistant sleeve connected to the adapter assembly and the other end of the wear-resistant and heat-resistant sleeve connected to the plug assembly.

[0016] Preferably, the plug component is a hollow structure, and the interior of the hollow structure is provided with a middle partition, which divides the interior of the hollow plug component into two small hollow areas, namely the left small hollow area and the right small hollow area.

[0017] Metal fasteners are installed on the inner sides of both the left and right small hollow areas.

[0018] The metal wire inside the conductor is securely connected to the metal fasteners in the left and right small hollow areas. This connection design ensures good stability between the metal wire inside the conductor and the metal fasteners inside the plug, preventing friction damage caused by relative displacement between the plug and the metal wire inside the conductor.

[0019] Preferably, the front end of the plug has a laterally irregular snap-fit ​​connector, and the rear end of the snap-fit ​​connector is connected to a limiting and stabilizing part. The limiting and stabilizing part and the laterally irregular snap-fit ​​connector are connected as a whole to form the plug.

[0020] Preferably, the end of the limiting and stabilizing part has a square slot. The square slot can ensure that the conductive wire harness is firmly confined in the hollow area within the limiting and stabilizing part. The limiting and stabilizing part and the laterally irregular snap-fit ​​connector can ensure that the temperature sensor does not shift when connected to the vehicle's central control system and will not undergo lateral displacement.

[0021] Preferably, the lower part of the plug can be equipped with a secondary locking element.

[0022] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0023] 1. This utility model uses a rotating card assembly to connect the temperature sensing component to the wire in a straight line at 180°, with a 90° right-angle turn; the rotating card assembly has a turning card connector and a plug-in stable connector, and the two are connected by a detachable structure. When the components in the detachable rotating card assembly are damaged, they can be replaced. This detachable structure design can save costs and is convenient to disassemble and assemble.

[0024] The steering connector has a hollow internal structure. The bottom of the steering connector is a square connector body, and the side of the steering connector has a sloping turntable area. The top of the steering connector has a square hollow connecting part, which can prevent the end of the temperature sensing component from directly rubbing against the wire connection area. A hollow plug-in connector is installed on one side of the plug-in connector. The bottom of the plug-in connector is a square shell with grooves on the side. The grooves match the size of the square connector body at the bottom of the steering connector. The hollow plug-in connector and the square shell are integrated to form the plug-in connector.

[0025] 2. There are two conductors, and the outer sides of the two conductors are wrapped in a figure-eight shape to prevent mutual friction and relative displacement between the two conductors. This makes it easier to install the wear-resistant and heat-resistant sleeve and prevents displacement.

[0026] 3. By installing wear-resistant and heat-resistant sleeves on the outside of the wire, the wear resistance, abrasion resistance, and anti-breakage performance of the wire of the temperature sensor can be enhanced when the car equipped with the temperature sensor is driving or encountering bumpy road conditions, thus extending the service life of the temperature sensor wire.

[0027] 4. The plug is made of hollow material, with a partition plate inside dividing the interior into two small hollow areas: a left small hollow area and a right small hollow area. Metal fasteners are installed on the inner sides of both the left and right small hollow areas. The metal wire inside the conductor is securely connected to these metal fasteners. This design ensures a stable connection between the metal wire inside the conductor and the metal fasteners inside the plug, preventing friction damage due to relative displacement between the plug and the metal wire.

[0028] The front end of the plug has a laterally irregular snap-fit ​​connector, and the rear end of the snap-fit ​​connector is connected to a limiting and stabilizing part. The end of the limiting and stabilizing part has a square slot. The square slot can ensure that the conductive wire harness is firmly confined in the hollow area within the limiting and stabilizing part. The limiting and stabilizing part and the laterally irregular snap-fit ​​connector can ensure that the temperature sensor does not shift or undergo lateral displacement when connected to the car's central control system.

[0040] Example 1:

[0041] Reference Figures 1-3 A detachable and stable temperature sensor for automotive air conditioning evaporators includes a temperature sensing component 1, a wire 2, a plug 3, and a wear-resistant and heat-resistant sleeve 4. The temperature sensing component 1 is connected to one end of the wire 2, and the other end of the wire 2 is connected to the plug 3. The wear-resistant and heat-resistant sleeve 4 is fitted over the wire 2.

[0042] It also includes: a card adapter 5, which enables the temperature sensing component 1 to be connected to the wire 2 in a straight line at 180° and to be connected at a right angle at 90°.

[0043] The card-turning assembly 5 has a card-turning connector 501 and a plug-in stable connector 502. The card-turning connector 501 is mounted on the side of the plug-in stable connector 502. The temperature sensing component 1 is mounted on the card-turning connector 501. The wire 2 connected to the temperature sensing component 1 is mounted on the plug-in stable connector 502. The card-turning connector 501 can change the direction of the connection between the temperature sensing component 1 and the wire 2. The card-turning connector 501 and the plug-in stable connector 502 are detachably connected.

[0044] The steering connector 501 has a hollow internal structure. The bottom of the steering connector 501 is a square connector body. The side of the steering connector 501 is provided with a sloping turntable area. The top of the steering connector 501 is provided with a square hollow connecting part. The square hollow connecting part can prevent the end of the temperature sensing component 1 from directly rubbing against the connection area of ​​the wire 2. The bottom of the steering connector 501 is equipped with a plug-in stable connector 502.

[0045] A hollow connector is installed on one side of the plug-in connector 502. The bottom of the plug-in connector 502 is a square shell with grooves on its side. The grooves match the size of the square snap-fit ​​body at the bottom of the steering snap-fit ​​connector 501. The hollow connector and the square shell are integrated to form the plug-in connector 502.

[0046] The temperature sensing component 1 includes a temperature sensing chip 101, epoxy resin, Dumé wire 102, copper strip 103 and glass layer 104. The epoxy resin is mounted on the outside of the temperature sensing chip 101. The Dumé wire 102 is connected to the temperature sensing chip 101 and its other end is connected to the copper strip 103. The glass layer 104 is mounted on the outside of the temperature sensing chip 101, the Dumé wire 102 and the copper strip 103.

[0047] There are two conductors 2. The outer sides of the two conductors 2 are wrapped in a figure-eight shape to prevent mutual friction and relative displacement between the two conductors 2. This makes it easier to install the wear-resistant and heat-resistant sleeve 4 and prevents it from shifting.

[0048] By installing a wear-resistant and heat-resistant sleeve 4 on the outside of the wire 2, the wear resistance, abrasion resistance, and anti-breakage performance of the wire 2 of the temperature sensor can be enhanced when the car equipped with the temperature sensor is driving or encountering bumpy road conditions, thus extending the service life of the wire 2 of the temperature sensor.

[0049] Example 2: Refer to Figures 1-4 Based on Example 1, the difference is that the plug 3 is a hollow structure with a middle partition inside. The middle partition divides the interior of the hollow plug 3 into two small hollow areas, namely the left small hollow area and the right small hollow area. Metal fasteners are installed on the inner side of the left small hollow area and the right small hollow area. The metal wire inside the wire 2 is stably connected to the metal fasteners in the left small hollow area and the right small hollow area. This connection design can ensure good connection stability between the metal wire inside the wire 2 and the metal fastener inside the plug 3, and prevent the plug 3 from being damaged by friction due to relative displacement between the metal wire inside the wire 2.

[0050] The front end of the plug 3 has a laterally irregular snap-fit ​​connector 301, and the rear end of the snap-fit ​​connector 301 is connected to a limiting and stabilizing part 302.

[0051] The end of the limiting and stabilizing part 302 has a square slot. The square slot can ensure that the conductive wire harness is firmly confined in the hollow area within the limiting and stabilizing part. The limiting and stabilizing part 302 and the laterally irregular snap connector 301 can ensure that the temperature sensor does not shift when connected to the vehicle's central control system and will not undergo lateral displacement.

[0052] Example 3:

[0053] Reference Figures 1-3 , Figure 5 Based on Embodiment 1, the difference is that the plug 3 can be Figure 5 In another structure shown, the lower part of the plug 3 can be equipped with a secondary locking member 303. The secondary locking member 303 can lock the plug 3 securely to the connection area of ​​the vehicle's central control system and prevent non-locking vibration from occurring at the connection area of ​​the plug 3 and the vehicle's central control system.

[0054] Example 4:

[0055] Reference Figure 1 , Figures 6-7 Based on Embodiment 1, the difference is that the card transfer component 5 can also be replaced with Figure 6 The structure of the novel rotating card component shown is that the novel rotating card component is installed in the connection area between the temperature sensing component 1 and the wire 2. The novel rotating card component can form a corrugated turning area at the connection area between the temperature sensing component 1 and the wire 2, so that the temperature sensing component 1 and the wire 2 form a turning connection through the corrugated turning area, thereby changing the connection direction between the temperature sensing component 1 and the wire 2.

[0056] The new type of card-turning component is designed with a detachable assembly method. The new type of card-turning component is composed of a turning card connector 501 and a plug-in stable connector 502.
