Description
Technical Field
[0001] This application relates to the field of automotive transmission connector technology, specifically a high-temperature resistant and sealed automotive exhaust gas sensor wiring harness transmission connector. Background Technology
[0002] The automotive exhaust gas sensor wiring harness transmission connector is a key component connecting the exhaust gas sensor to the vehicle's electronic control system. Its core function is to ensure that the exhaust gas composition data or temperature signal collected by the sensor can be stably and accurately transmitted to the ECU to achieve engine combustion optimization, emission control, and fault diagnosis. The performance of these connectors directly affects exhaust gas emission compliance and engine efficiency. If there is poor contact or signal distortion, it may lead to decreased fuel economy, reduced power, or even excessive emissions.
[0003] However, it has been found in the existing technology that when the transmission connector of the automotive exhaust gas sensor wiring harness is in use, the temperature of the working area is high, and the existing connector is exposed and lacks protection, resulting in insufficient high temperature resistance and sealing performance of the connector, leading to a reduced service life. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a high-temperature resistant and sealed automotive exhaust gas sensor wiring harness transmission connector. It has advantages such as improving the high-temperature resistance of the connector through the external housing and improving the sealing performance of the connector through the setting of the sealing strip, thereby extending the service life, and solving the problems mentioned in the background technology.
[0005] To achieve the above objectives, this application provides the following technical solution: a high-temperature resistant and sealed automotive exhaust gas sensor wiring harness transmission connector, comprising a first connector, a second connector inserted into the right end of the first connector, a fixing plate fixedly connected to the outer surface of the first connector, a first aluminum alloy shell and a second aluminum alloy shell provided on the right side of the fixing plate, a limit ring fixedly connected to the outer surface of the second connector, a first sealing strip fixedly connected to the inner sidewalls of both the first and second aluminum alloy shells, two pressure blocks fixedly connected to the bottom surface of the first aluminum alloy shell, two placement grooves opened on the upper surface of the second aluminum alloy shell, a second sealing strip fixedly connected to the inner wall of each placement groove, and the inner wall of each placement groove being adapted to the outer surface of the corresponding pressure block, and a wiring harness body fixedly installed on the sides of the first and second connectors that are far apart from each other.
[0006] The above scheme involves setting a second connector at the right end of the first connector, mounting a fixing plate on the outer surface of the first connector for a fixed connection, and placing a first aluminum alloy shell and a second aluminum alloy shell on the right side of the fixing plate. A limiting ring is then mounted on the outer surface of the second connector for a fixed connection. A first sealing strip is placed on the inner wall of the first and second aluminum alloy shells. When the first and second aluminum alloy shells are connected, the first sealing strip fits snugly against the outer surface of the second connector, and the limiting ring effectively blocks the position of the first and second aluminum alloy shells, thus achieving the installation of the first... The positioning and installation of the aluminum alloy shell and the second aluminum alloy shell involves setting a pressure block on the bottom surface of the first aluminum alloy shell and creating two placement grooves on the upper surface of the second aluminum alloy shell. The second sealing strip is installed on the inner wall of the placement groove. When the first aluminum alloy shell and the second aluminum alloy shell are connected, the pressure block can be inserted into the placement groove through the adaptation between the pressure block and the placement groove. At this time, the pressure block compresses the second sealing strip, thereby enabling the device to improve the high temperature resistance of the first and second joints through the assembly of the first and second aluminum alloy shells, and to improve the sealing performance between the first and second joints through the first and second sealing strips, thus extending the service life.
[0007] Furthermore, the right side of the fixing plate is fixedly connected with connecting rods arranged at equal intervals, and the right side of the fixing plate is provided with guide rods arranged at equal intervals, the end of each guide rod being fixedly connected to the inner wall of the corresponding connecting rod.
[0008] With the above solution, the connecting rod is installed on the right side of the fixed plate for a fixed connection, and the guide rod is placed on the right side of the fixed plate. The end of the guide rod is fixed to the corresponding connecting rod, so that the connecting rod and the guide rod can be fixed on the right side of the fixed plate.
[0009] Furthermore, connecting blocks are fixedly connected to the front and back of both the first and second aluminum alloy shells, and the inner wall of each connecting block is slidably connected to the outer surface of the corresponding guide rod.
[0010] The above scheme involves installing connecting blocks on the front and back of the first and second aluminum alloy shells, and connecting the connecting blocks to the corresponding guide rods in a sliding connection configuration. This allows the guide rods to limit the connecting blocks, thereby limiting the first and second aluminum alloy shells and ensuring that the first and second aluminum alloy shells can only slide in the upper and lower positions of the first and second joints.
[0011] Furthermore, connecting arms are fixedly connected to the upper and lower surfaces of the fixing plate, and a sliding rod is slidably connected to the inner wall of each connecting arm. The end of each sliding rod is fixedly connected to the outer surface of the corresponding first aluminum alloy shell and second aluminum alloy shell, and two slots are opened on the left side of each sliding rod.
[0012] The above scheme involves installing connecting arms on the upper and lower surfaces of the fixed plate, and setting a sliding rod on the inner wall of the connecting arm. The connecting arm limits the sliding rod, allowing it to slide up and down. The sliding rod is connected to the corresponding first and second aluminum alloy shells, so that when the operator pulls the sliding rod, it can move the corresponding first and second aluminum alloy shells. A slot is formed on the outer surface of the sliding rod to achieve positioning.
[0013] Furthermore, each of the connecting arms has a groove on its opposite side, and a slider is slidably connected to the inner wall of each groove.
[0014] The above solution involves creating a groove on the side of the connecting arms that are far apart from each other, and setting a slider on the inner wall of the groove. The groove limits the slider, allowing it to slide along the groove.
[0015] Furthermore, a round rod is fixedly connected to the inner wall of each groove, and the outer surface of each round rod is slidably connected to the inner wall of the corresponding slider.
[0016] The above method involves installing a round rod on the inner wall of the slide and connecting the round rod to the corresponding slider, thereby enabling the round rod to further limit the slider and ensure the stability of the slider during movement.
[0017] Furthermore, each slider has a connecting plate fixedly connected to the side of each slider that is far apart from each other, and each slider is adapted to a corresponding slot.
[0018] With the above solution, a connecting plate is installed on the side of the slider that is far apart from each other, so that the operator can pull the connecting plate to move the slider laterally and adapt the outer surface of the slider to the slot. When the slider is connected to the slot, the sliding rod can be locked. When connected to different slots, the first aluminum alloy shell or the second aluminum alloy shell can be stopped in different positions.
[0019] Furthermore, a spring is fixedly connected to the left side of each slider, and the other end of each spring is fixedly connected to the inner sidewall of the corresponding groove.
[0020] The above method involves installing a spring on the left side of the slider and fixing the other end of the spring to the corresponding groove, thereby enabling the spring to press the slider firmly and ensuring that the slider can connect with the corresponding groove.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This high-temperature resistant and sealed automotive exhaust gas sensor wiring harness transmission connector comprises a first aluminum alloy shell, a second aluminum alloy shell, a first sealing strip, and a second sealing strip. After the first and second connectors are connected, a limiting ring limits the first and second aluminum alloy shells, allowing them to be spliced onto the outside of the first and second connectors. At this time, the first sealing strip contacts the second connector, and a pressure block is inserted into the placement groove, compressing the second sealing strip. The spliced first and second aluminum alloy shells enhance the high-temperature resistance of the first and second connectors, while the first and second sealing strips enhance their sealing performance, thus extending their service life. During the assembly of the first and second aluminum alloy shells, the operator pulls the corresponding connecting plate to move the slider. The slider slides along the slide groove and compresses the spring, at which point the slider disengages from the slot. Subsequently, the corresponding sliding rod is moved, allowing the first and second aluminum alloy shells to move. When the first and second aluminum alloy shells are in place, the slider slides under the action of the spring, connecting with the corresponding slot to lock the first and second aluminum alloy shells, enabling rapid splicing of the first and second aluminum alloy shells.

The second connector 2 is located at the right end of the first connector 1, and the fixing plate 3 is installed on the outer surface of the first connector 1 for a fixed connection. A first aluminum alloy shell 4 and a second aluminum alloy shell 5 are located on the right side of the fixing plate 3.

The inner walls of the first aluminum alloy shell 4 and the second aluminum alloy shell 5 are both fixedly connected with the first sealing strip 7. The first sealing strip 7 is set on the inner wall of the first aluminum alloy shell 4 and the second aluminum alloy shell 5. When the first aluminum alloy shell 4 and the second aluminum alloy shell 5 are connected, the first sealing strip 7 can fit against the outer surface of the second connector 2, and the limiting ring 6 can block the position of the first aluminum alloy shell 4 and the second aluminum alloy shell 5, thereby realizing the positioning and installation of the first aluminum alloy shell 4 and the second aluminum alloy shell 5.
[0026] Please see Figure 1 , Figure 2 and Figure 3Two pressure blocks 8 are fixedly connected to the bottom surface of the first aluminum alloy shell 4, and two placement grooves 9 are opened on the upper surface of the second aluminum alloy shell 5.

When the first aluminum alloy shell 4 and the second aluminum alloy shell 5 are connected, the pressure block 8 can be inserted into the interior of the placement groove 9 through the adaptation of the pressure block 8 and the placement groove 9. At this time, the pressure block 8 compresses the second sealing strip 10, so that the device can improve the high temperature resistance of the first connector 1 and the second connector 2 through the assembly of the first aluminum alloy shell 4 and the second aluminum alloy shell 5, and improve the sealing performance between the first connector 1 and the second connector 2 through the first sealing strip 7 and the second sealing strip 10, thereby extending the service life.
[0027] Please see Figure 2 , Figure 4 and Figure 5 A connecting rod 12 arranged at equal intervals is fixedly connected to the right side of the fixing plate 3. A guide rod 14 arranged at equal intervals is also provided on the right side of the fixing plate 3.

The connecting rod 12 is installed on the right side of the fixing plate 3 for a fixed connection, and the guide rod 14 is positioned on the right side of the fixing plate 3, with its end fixed to the corresponding connecting rod 12. This allows the connecting rod 12 and guide rod 14 to be fixed to the right side of the fixing plate 3. The first aluminum alloy shell 4 and the second aluminum alloy shell 5 are also present. Connecting blocks 13 are fixedly connected to both the front and back of the first aluminum alloy shell 4 and the second aluminum alloy shell 5.

The connecting blocks 13 are installed on the front and back of the first aluminum alloy shell 4 and the second aluminum alloy shell 5, and the connecting blocks 13 are connected to the corresponding guide rods 14 in a sliding connection. This allows the guide rods 14 to limit the connecting blocks 13, thereby limiting the first aluminum alloy shell 4 and the second aluminum alloy shell 5, ensuring that the first aluminum alloy shell 4 and the second aluminum alloy shell 5 can only slide in the upper and lower positions of the first connector 1 and the second connector 2.
[0028] Please see Figure 2 , Figure 4 and Figure 5Connecting arms 15 are fixedly connected to the upper and lower surfaces of the fixing plate 3. A sliding rod 16 is slidably connected to the inner wall of each connecting arm 15. The end of each sliding rod 16 is fixedly connected to the outer surface of the corresponding first aluminum alloy shell 4 and second aluminum alloy shell 5. Two slots 17 are provided on the left side of each sliding rod 16. The connecting arms 15 are installed on the upper and lower surfaces of the fixing plate 3, and the sliding rods 16 are provided on the inner walls of the connecting arms 15. The connecting arms 15 limit the movement of the sliding rods 16, allowing them to slide up and down. The sliding rods 16 are connected to the corresponding first aluminum alloy shell 4 and second aluminum alloy shell 5. The second aluminum alloy shell 5 is connected so that when the operator pulls the slide rod 16, it can drive the corresponding first aluminum alloy shell 4 and second aluminum alloy shell 5 to move. A slot 17 is opened on the outer surface of the slide rod 16 to achieve positioning of the slot 17. Each connecting arm 15 has a sliding groove 18 on the side away from each other. A slider 19 is slidably connected to the inner wall of each sliding groove 18. The sliding groove 18 is opened on the side away from each other of the connecting arms 15, and the slider 19 is set on the inner wall of the sliding groove 18. The sliding groove 18 is used to limit the slider 19, so that the slider 19 can slide along the sliding groove 18.
[0029] Please see Figure 5 Each slide groove 18 has a round rod 22 fixedly connected to its inner wall. The outer surface of each round rod 22 is slidably connected to the inner wall of the corresponding slider 19. The round rod 22 is installed on the inner wall of the slide groove 18 and connected to the corresponding slider 19, so that the round rod 22 can further limit the slider 19 and ensure the stability of the slider 19 when it moves. Each slider 19 has a connecting plate 20 fixedly connected to its opposite side. Each slider 19 is adapted to the corresponding slot 17. The connecting plate 20 is installed on the opposite side of the slider 19, so that the operator can move the slider 19 laterally by pulling the connecting plate 20. The slider 19 is adapted to the slot 17 so that when the slider 19 is connected to the slot 17, the slide rod 16 can be locked. When connected to different slots 17, the first aluminum alloy shell 4 or the second aluminum alloy shell 5 can be stopped in different positions. A spring 21 is fixedly connected to the left side of each slider 19. The other end of each spring 21 is fixedly connected to the inner side wall of the corresponding slide groove 18. The spring 21 is installed on the left side of the slider 19 and the other end of the spring 21 is fixed to the corresponding slide groove 18, so that the spring 21 can press the slider 19 tightly, thereby ensuring that the slider 19 can be connected to the corresponding slot 17.
[0030] The working principle of the above embodiment is as follows: First, the first connector 1 and the second connector 2 are connected. Then, the operator pulls the corresponding connecting plate 20 to move the corresponding slider 19. At this time, the slider 19 moves along the slide groove 18 and compresses the spring 21. After the slider 19 is disconnected from the slot 17, the operator moves the corresponding slide rod 16, which drives the corresponding first aluminum alloy shell 4 and second aluminum alloy shell 5 to move. Through the connection between the connecting block 13 and the guide rod 14, the limit is achieved when the first aluminum alloy shell 4 and the second aluminum alloy shell 5 are raised and lowered, until the first sealing strip 7 in the first aluminum alloy shell 4 and the second aluminum alloy shell 5 are in contact with the surface of the second connector 2. At this time, the pressure block 8 is inserted. After the first aluminum alloy shell 4 and the second aluminum alloy shell 5 are installed in place, the slider 19 is reset under the action of the spring 21. At this time, the slider 19 is connected to the corresponding slot 17, completing the fixation of the first aluminum alloy shell 4 and the second aluminum alloy shell 5, so that the first aluminum alloy shell 4 and the second aluminum alloy shell 5 can cover the outside of the first connector 1 and the second connector 2. The high temperature resistance of the first connector 1 and the second connector 2 is improved by assembling the first aluminum alloy shell 4 and the second aluminum alloy shell 5, and the sealing performance between the first connector 1 and the second connector 2 is improved by the first sealing strip 7 and the second sealing strip 10, thereby achieving the effect of extending the service life.
