Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Refer to Figures 1-3 , a rubber sealing assembly for an automotive sensor, including a sensor 1 and a connector 2 installed on an automobile. A connecting pipe 3 is installed on the sensor 1, an interface 4 is installed in the connecting pipe 3, a wire 5 is arranged in the connector 2, a plug 6 is installed at one end of the wire 5 close to the connecting pipe 3, and the other end of the wire 5 is connected to the automobile. A plurality of steel balls 7 are slidably connected to the connecting pipe 3, a groove 8 is formed in the connector 2, and the steel balls 7 are slidably fitted on the groove 8. A spring 9 is sleeved on the connecting pipe 3, and a push tube 10 is sleeved on the outer periphery of the spring 9. The push tube 10 is slidably connected to the connecting pipe 3.

[0021] When the sealing assembly is used, the staff aligns the connector 2 with the connecting pipe 3, and then moves the connector 2 towards the connecting pipe 3. During the movement, the push tube 10 is pushed towards the connecting pipe 2, thereby driving the spring 9 to be compressed in the same direction, and further eliminating the acting force of the spring 9 on the plurality of steel balls 7, so that the plurality of steel balls 7 can move towards the outer periphery of the connecting pipe 3 under the influence of the thrust of the connector 2 when they contact the connector 2, providing space for the subsequent movement of the connector 2. When the groove 8 and the plurality of steel balls 7 are at the same horizontal plane, the steel balls 7 fall into the groove 8, and then the push tube 10 is released. The push tube 10 moves towards the connector 2 under the influence of the elastic force of the spring 9 and restricts the plurality of steel balls 7 on the inner wall surface of the push tube 10, so that the plurality of steel balls 7 are stably connected between the connector 2 and the connecting pipe 3, and then the connection between the connector 2 and the connecting pipe 3 is completed. When the connector 2 and the connecting pipe 3 are connected, the interface 4 and the plug 6 are driven to be connected, so as to connect the sensor 1 with the connector 2 on the automobile, and further achieve the purpose of centralized processing of various types of data transmission of the automobile. The sealing assembly has a simple structure and is convenient to install, effectively reducing the production cost and improving the installation efficiency.

[0022] Specifically, in this embodiment, a plurality of receiving cavities 11 are formed in the connecting pipe 3. The diameter of the receiving cavity 11 is smaller than the diameter of the steel balls 7, and the number of the receiving cavities 11 is the same as that of the steel balls 7. The steel balls 7 are slidably fitted in the corresponding receiving cavities 11, so that the plurality of steel balls 7 can be slidably mounted on the connecting pipe 3 through the corresponding receiving cavities 11, thereby facilitating the change of the position of the steel balls 7 on the connecting pipe 3 to make the steel balls 7 fall on the grooves 8, and further completing the connection between the connecting pipe 3 and the connector 2.

[0023] Specifically, in this embodiment, a moving groove 12 is formed on the outer surface of the connecting pipe 3. The spring 9 is sleeved on the moving groove 12. When the spring 9 is forced to squeeze towards the sensor 1, one end of the spring 9 close to the sensor 1 contacts and abuts against one end wall surface of the moving groove 12, so that the spring 9 can be effectively compressed, and further the influence of the spring 9 on the plurality of steel balls 7 can be eliminated.

[0024] Specifically, in this embodiment, a positioning ring 13 is installed on the inner wall surface of the push pipe 10. The inner wall surface of the positioning ring 13 contacts the connecting pipe 3, so that a receiving space can be formed between the push pipe 10 and the connecting pipe 3, and the spring 9 is slidably installed in this space, so that the movement of the push pipe 10 can drive the spring 9 to move synchronously.

[0025] Specifically, in this embodiment, a limiting groove 16 is formed on the periphery of the connector 2. The outer wall surface of the limiting groove 16 contacts the inner wall surface of the connecting pipe 3, so that the front end of the connector 2 can be inserted into the connecting pipe 3 through the limiting groove 16 to complete the preliminary connection between the connector 2 and the connecting pipe 3.

[0026] Specifically, in this embodiment, a limiting ring 14 is installed on the inner wall of the connecting pipe 3. The limiting ring 14 contacts the outer wall surface of the connector 2. When the connector 2 moves into the connecting pipe 3, the limiting ring 14 can contact the connector 2 and limit the connector 2 at a specific position, thereby facilitating the steel balls 7 to fall into the grooves 8.

[0027] Specifically, in this embodiment, connecting rings 15 are installed on the inner walls of both the connecting pipe 3 and the connector 2. The two connecting rings 15 are respectively adapted to the interface 4 and the plug 6, so that the interface 4 and the plug 6 can be respectively connected to the connecting pipe 3 and the connector 2 through the corresponding connecting rings 15, thereby fixing the positions of the interface 4 and the plug 6 in the connecting pipe 3 and the connector 2, so that the interface 4 and the plug 6 can be accurately connected.
