Description

Technical Field

[0001] The utility model relates to the technical field of oil level sensors, in particular to an external connector for an ultrasonic oil level sensor. Background Art

[0002] The working principles of non-contact liquid level sensors are generally divided into two types. One is to calculate the distance between the sensor and the liquid surface through the time of ultrasonic emission and reception of signals. Since ultrasonic waves will generate echoes on the liquid surface, the distance between the liquid level sensor and the bottom of the container is certain, and the distance between the sensor and the liquid surface can be calculated. The second is to measure the size of the liquid charge through a capacitive detection device. The sensor is installed at different positions of the container or pipeline. When the induced charge is greater than the set value, the liquid level height indication can be output; however, the external connector of the existing ultrasonic oil level sensor is directly plugged in during actual use, and the plug-in column in the external connector cannot be inserted into the corresponding plug-in hole at one time, making it very easy for the plug-in column to hit other positions, causing the plug-in column to be easily bent and damaged. In the process of plugging the external connector, workers cannot intuitively observe the relative position between the plug-in column and the plug-in hole, requiring workers to test a little bit, which will reduce the installation efficiency of the ultrasonic sensor. At the same time, the external connector of the existing ultrasonic oil level sensor lacks a corresponding fixed structure after plugging, making the external connector prone to accidental detachment, thereby interfering with the vehicle's oil level detection results.

[0018] In this embodiment, when the external connector of the ultrasonic oil level sensor needs to be installed, the male connector 9 is partially embedded in the plug-in groove 6 opened in the female connector 2. When the male connector 9 is rotated, the guide plate 10 can face the guide groove 15, and the male connector 9 is pushed to move again by the fixing plate 12. Then, during the process of the male connector 9 being embedded in the plug-in groove 6, the plug-in column 7 in the female connector 2 can be smoothly embedded in the plug-in hole opened in the male connector 9 at one time. After the plug-in column 7 is partially embedded in the plug-in hole, the main fastening plate 8 will contact the auxiliary fastening plate 11, and the worker rotates the rotating plate 5, and the rotating plate 5 drives the main fastening plate 8 to move. The fixing plate 8 rotates synchronously, so the main fastening plate 8 can be screwed to the auxiliary fastening plate 11 through a threaded structure, and the screw connection structure between the main fastening plate 8 and the auxiliary fastening plate 11 can assist in promoting the plug-in stability of the male connector 9 and the female connector 2.

The bumps have a hemispherical structure. At the same time, the sizes of the limiting ring 4 and the limiting groove 16 formed in the rotating plate 5 are adapted to each other.

[0024] In this embodiment, as Figure 1 , Figure 3 and Figure 4 , the setting of the limiting ring 4 enables the rotating plate 5 to rotate stably on the outer side surface of the female connector 2. Moreover, the structural setting of the bumps can not only enhance the stability of the fixation between the fastening block 13 and the limiting ring 4, but also reduce the wear speed of the fastening layer provided on the surface of the fastening block 13.
