Description

Technical Field

[0001] This utility model relates to the field of engine technology, specifically to an oil pressure sensor plug-in structure. Background Technology

[0002] The H25 engine wiring harness oil pressure sensor plug-in terminal is a pull-back terminal, which is inserted from the plug-in end backward. During insertion and removal, it is easy to cause loosening and poor contact. During assembly, when the installation space is small, it is not easy to confirm the plug-in installation direction when it is round. Blind insertion will damage the terminal and cause poor contact.

[0003] Existing oil pressure sensor plug-in uses circular pull-back terminals. These terminals are prone to loosening during blind insertion, leading to poor contact, damage, and affecting assembly quality. However, some plug-ins are not connected, allowing dust from the external environment to fall directly into them. If a lot of dust accumulates, it may cause static electricity, which in severe cases may cause short circuits in the electronic connectors, easily damaging the plug-in and reducing its lifespan to some extent.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-7The present invention provides a technical solution: the oil pressure sensor plug-in structure includes a plug-in body 1, a transmission assembly, and a locking assembly. A rectangular housing 3 is provided on one side of the plug-in body 1. Multiple terminals 4 are arranged in a linear array inside the housing 3. Two dustproof plates 7 are rotatably connected inside the housing 3. A first elastic unit is provided inside the plug-in body 1. A connecting block 17 is vertically slidably connected inside the plug-in body 1 through the first elastic unit. A button 2 is provided on the top of the connecting block 17. A heart-shaped groove is opened on one side of the connecting block 17. A locking position 28 is located at the top of the heart-shaped groove and at the bottom of the heart-shaped groove. Unlocking station 29, a swing rod 22 is oscillatingly connected inside the plug body 1. A locking block 23 is provided on one side of the swing rod 22. The transmission component is driven by the downward movement of button 2 to make the two dustproof plates 7 rotate outward in the opposite direction and open the opening of the housing 3. The locking component is driven by the pressing action of button 2 to make the locking block 23 move unidirectionally along the heart-shaped groove and alternately position itself at the locking station 28 and the unlocking station 29, thereby making button 2 move up and down. Specifically, through the linearly arranged terminals 4 inside the housing 3, the plug can be quickly positioned during installation, reducing the number of re-insertions and reducing poor contact caused by damage to the terminals 4.

[0023] As a preferred technical solution, the transmission assembly includes a push block 16, which is fixedly connected to one side of the connecting block 17. A second elastic unit is provided inside the plug body 1. A contact block 11 is horizontally slidably connected inside the plug body 1 via the second elastic unit. The top of the contact block 11 is inclined. The bottom of the push block 16 slidably abuts against the top of the contact block 11. A connecting bracket 9 is provided at one end of the contact block 11 near the housing 3. Two racks 8 are symmetrically arranged on the connecting bracket 9. Two first rotating shafts 5 are symmetrically arranged inside the housing 3, and a gear 6 is provided inside each of the two dustproof plates 7. The two gears 6 are respectively rotatably engaged with the two first rotating shafts 5. The two racks 8 and the two gears 6... The corresponding meshing connection is as follows: Specifically, two first guide grooves 10 are symmetrically and horizontally opened inside the housing 3, and two racks 8 are slidably connected in the two first guide grooves 10 respectively. A second guide groove 15 is horizontally opened inside the plug body 1, and the abutment block 11 is slidably connected in the second guide groove 15. During the process of the connecting block 17 driving the pushing block 16 to move down, the pushing block 16 squeezes the abutment block 11, causing the abutment block 11 to slide away from the housing 3. At the same time, it drives the two racks 8 to slide horizontally. The two racks 8 are driven by meshing with the corresponding gears 6, which drives the two dustproof plates 7 to rotate around the corresponding first rotating shaft 5, thereby opening the opening of the housing 3 to facilitate the insertion of the sensor.

[0024] As a preferred technical solution, the second elastic unit includes a second spring 13 and a guide rod 12. A guide rod 12 is horizontally provided inside the plug body 1, and a groove 14 is provided inside the abutment block 11. The abutment block 11 is slidably sleeved with the guide rod 12 through the groove 14, and the second spring 13 is sleeved on the guide rod 12. Specifically, the guide rod 12 restricts the movement direction of the abutment block 11, and the second spring 13 is a compression spring. The abutment block 11 can be reversed and reset by the action of the second spring 13, so that the two dustproof plates 7 rotate in opposite directions to seal the opening of the housing 3 again, preventing dust from entering the interior of the housing 3 and damaging the plug body 1.

[0025] As a preferred technical solution, the locking assembly includes a second rotating shaft 21, with a swing rod 22 rotatably connected to the second rotating shaft 21. The heart-shaped groove includes a rising slide 24, a guide groove 25, a release groove 26, and a descending slide 27 connected end-to-end in sequence. The locking block 23 is slidably connected to the rising slide 24, guide groove 25, release groove 26, and descending slide 27 in sequence. The rising slide 24 and descending slide 27 are connected in a V-shape. The unlocking station 29 is located at the connection between the rising slide 24 and descending slide 27. The guide groove 25 and release groove 26 are connected in a V-shape. The locking station 28 is located at the connection between the rising slide 24 and descending slide 27. Specifically, at the connection of 27, the connection between the rising slide 24 and the guide groove 25 forms a first transition position 30, and the connection between the disengagement groove 26 and the descending slide 27 forms a second transition position 31. When button 2 is pressed, the locking block 23 moves upward from the lower position. When the locking block 23 moves from the rising slide 24 to the first transition position 30 and enters the guide groove 25, it will move deeper into the guide groove 25 under the elastic force of the first elastic unit, thus moving to the locking position 28. Since the guide groove 25 and the disengagement groove 26 are connected in a V-shape, the locking block 23 can be positioned at the locking position 28. The position of the connecting block 17 is fixed, and the unfolded position of the two dustproof plates 7 is also fixed, facilitating one-handed operation and eliminating the need for continuous pressing of button 2. Then, button 2 is pressed again, and locking block 23 moves upward. Locking block 23 will move along the bottom of the inclined release groove 26 towards the second transition position 31, without moving towards the guide groove 25. When locking block 23 moves to the second transition position 31, button 2 is released. Under the action of the first elastic unit, button 2 drives connecting block 17 to move upward, while locking block 23 moves downward. Locking block 23 enters the descending slide groove 27, and the movement of locking block 23 along the descending slide groove 27... 7. Move to the unlocking station 29 and position the locking block 23 at a lower position. At this time, the connecting block 17 has driven the pushing block 16 to disengage from the abutting block 11. The action of the second spring 13 causes the abutting block 11 to move in the opposite direction and reset, so that the two dustproof plates 7 rotate in the opposite direction to seal the opening of the housing 3 again, preventing dust from entering the housing 3 and damaging the plug-in body 1. After the insertion is completed, when the button 2 is pressed to make the locking block 23 disengage from the locking station 28, both dustproof plates 7 attempt to rotate in the opposite direction, which has a clamping force on the sensor, making the insertion of the sensor into the plug-in body 1 more stable.

[0026] As a preferred technical solution, the first elastic unit includes a telescopic rod 18 and a first spring 20 sleeved on the telescopic rod 18. A third guide groove 19 is vertically opened inside the plug body 1. The two ends of the telescopic rod 18 are fixedly connected to the connecting block 17 and the groove wall of the third guide groove 19, respectively. Specifically, the telescopic rod 18 plays a guiding role, and the first spring 20 is a tension spring. The connecting block 17 moves upward and resets through the action of the first spring 20.

[0027] Working principle: The oil pressure sensor plug-in structure uses linearly arranged terminals 4 within the housing 3, enabling quick positioning during installation, reducing the number of re-insertion attempts, and minimizing contact problems caused by damage to the terminals 4. When the plug-in body 1 is not connected, the housing 3 can be sealed by two dustproof plates 7 to prevent external dust from directly entering the plug-in. When the plug-in is needed, pressing button 2 moves the connecting block 17 downwards. As the connecting block 17 moves the pushing block 16 downwards, the pushing block 16 presses against the abutment block 11, causing the abutment block 11 to slide away from the housing 3, simultaneously driving... The two racks 8 slide horizontally, and through meshing with the corresponding gears 6, they drive the two dustproof plates 7 to rotate around the corresponding first rotating shaft 5, thereby opening the housing 3 to facilitate the insertion of the sensor. When the button 2 is pressed, the locking block 23 moves upward from the lower position. When the locking block 23 moves from the rising slide 24 to the first transition position 30 and enters the guide groove 25, it will move deeper into the guide groove 25 under the action of the first spring 20, thus moving to the locking position 28. Since the guide groove 25 and the release groove 26 are connected in a V-shape, the locking block 23 can be positioned at the locking position 28, that is... The position of the connecting block 17 is fixed, and the unfolded position of the two dustproof plates 7 is also fixed, facilitating one-handed operation and eliminating the need for continuous pressing of button 2. Then, pressing button 2 again causes the locking block 23 to move upward. The locking block 23 will move along the bottom of the inclined release groove 26 towards the second transition position 31, without moving towards the guide groove 25. When the locking block 23 moves to the second transition position 31, releasing button 2 allows button 2 to move the connecting block 17 upward under the action of the first spring 20, while the locking block 23 moves downward. The locking block 23 enters the descending slide groove 27, and at this point, the connection is complete, and the locking block 23 disengages from the lock. At stop 28, both dustproof plates 7 attempt to rotate in the opposite direction, exerting a clamping force on the sensor, making the insertion of the sensor into the plug body 1 more stable. If the opening of the housing 3 is to be blocked, the locking block 23 will continue to move along the descending slide 27 to the unlocking station 29 for positioning, thereby positioning the locking block 23 at a lower position. At this time, the connecting block 17 has driven the pushing block 16 to disengage from the abutment block 11. The action of the second spring 13 causes the abutment block 11 to move in the opposite direction to reset, causing the two dustproof plates 7 to rotate in the opposite direction to block the opening of the housing 3 again, preventing dust from entering the interior of the housing 3 and damaging the plug body 1.
