AI Technical Summary
Existing automotive function controllers with porous sealing plugs experience reduced sealing performance under frequent plugging and unplugging and vibration-induced use scenarios, and lack effective moisture removal design, leading to increased risks of corrosion and electrical failure.
A multi-hole sealing plug for automotive function controllers, comprising a sealing plug and an elastic limiting component, is designed. The combination of the drainage hole in the transition section of the sealing plug and the elastic limiting component achieves a secure lock and allows water to sink and drain out, preventing the sealing plug from loosening and water accumulation, thus ensuring long-term reliability.
It improves the stability and waterproofness of the sealing plug, prevents loosening caused by long-term insertion and removal or vibration, effectively drains moisture, reduces the risk of corrosion and electrical failure, and improves the reliability of the controller.

Abstract
Description
Technical Field
[0001] This utility model relates to a multi-hole sealing plug for automotive function controllers. Background Technology
[0002] Multi-hole sealing plugs for automotive function controllers are used in modern vehicles to protect internal components from external environmental factors such as dust and moisture, ensuring electrical performance and safety. Existing multi-hole sealing plugs are typically simple in structure, providing only basic sealing functions. They are ill-suited for frequent insertion / removal or vibration-induced use, and their sealing effectiveness is prone to decline over long-term use. Furthermore, the lack of effective moisture drainage design allows water to seep into the device, increasing the risk of corrosion and electrical failure. These shortcomings affect the stability of the sealing plugs and the reliability of the vehicle controller. Improvements and optimizations are proposed to address these issues. Utility Model Content
[0003] To solve the above problems, the technical problem to be solved by this utility model is to provide a multi-hole sealing plug for automotive function controllers.
[0004] The technical solution adopted by the multi-hole sealing plug of the automotive function controller of this utility model is characterized by including a sealing plug and an elastic limiting member. The sealing plug has a square structure and includes a sealing plug front part, a sealing plug transition part and a sealing plug rear part arranged in sequence. The outer wall of the sealing plug transition part is provided with a sealing plug outer mounting groove for installing the elastic limiting member. The sealing plug front part and the sealing plug rear part both include a sealing plug body. The sealing plug body is provided with an array of controller wiring holes. The inner wall of the sealing plug body is provided with spaced-apart sealing plug inner telescopic protrusions in the controller wiring holes. The outer wall of the sealing plug body is provided with spaced-apart sealing plug outer telescopic protrusions.
[0005] The sealing plug transition section is provided with a sealing plug inner clearance port that communicates with the controller wiring hole, and the upper and lower ends of the sealing plug inner clearance port are provided with longitudinally arranged drainage holes.
[0006] The size of the transition portion of the sealing plug is less than or equal to the size of the front portion of the sealing plug.
[0007] The elastic limiting component is a snap ring.
[0008] The inner walls of the upper and lower sides of the sealing plug are provided with drainage slopes to facilitate water discharge. The drainage slopes are high at both ends and low in the middle, and the drainage hole is provided in the middle of the drainage slopes.
[0009] The front and rear outer end faces of the sealing plug are both provided with sealing plug positioning grooves.
[0010] The advantages of this multi-hole sealing plug for automotive function controllers are as follows: the locking function of the elastic limiting component makes the sealing plug more stable, preventing loosening and displacement caused by long-term insertion or pulling, thus ensuring the long-term reliability of the seal; the transition part of the sealing plug has a water-sinking function, and water can enter the water sink through the drain hole and be discharged from the housing, preventing water accumulation from affecting the controller.

[0017] like Figure 1-5As shown, the multi-hole sealing plug for automotive function controllers involved in this utility model includes a sealing plug 1 and an elastic limiting member 2. The sealing plug 1 has a square structure and includes a sealing plug front part 4, a sealing plug transition part 5, and a sealing plug rear part 6 arranged sequentially. The outer wall of the sealing plug transition part 5 is provided with a sealing plug outer mounting groove 8 for installing the elastic limiting member 2. The sealing plug front part 4 and the sealing plug rear part 6 both include a sealing plug body 9. The sealing plug body 9 is provided with controller wiring holes 10 arranged in an array. The inner wall of the sealing plug body 9 in the controller wiring holes 10 is provided with spaced-apart sealing plug inner telescopic protrusions 11, and the outer wall of the sealing plug body 9 is provided with spaced-apart sealing plug outer telescopic protrusions 12. The sealing plug transition part 5 is provided with a sealing plug inner clearance port 13 that communicates with the controller wiring hole 10. The sealing plug inner clearance port 13 has a longitudinally arranged drainage hole 14 at the middle of its upper and lower ends. After the sealing plug 1 is installed into the car function controller housing, the elastic limiting member 2 is opened to lock the sealing plug 1, effectively preventing its position displacement due to long-term insertion and pulling, and ensuring sealing performance. The sealing plug transition part 5 can sink water that enters the interior through the controller wiring hole 10. The water flows into the sinking tank of the car function controller housing corresponding to the sealing plug transition part 5 through the drainage hole 14 and is discharged through the housing drainage hole, so that the overall waterproofness is effectively guaranteed.
[0018] The size of the transition portion 5 of the sealing plug is smaller than or equal to the size of the front portion 4 of the sealing plug, which facilitates installation and improves installation efficiency.
[0019] The elastic limiting component 2 is a snap ring, which has a simple and reliable structure and is easy for personnel to operate.
[0020] The inner walls of the sealing plug 13 are provided with drainage slopes 16 on the upper and lower sides to facilitate water discharge. The drainage slopes 16 are high at both ends and low in the middle. The drainage hole 14 is provided in the middle of the drainage slopes 16 to facilitate water flow to the drainage hole and effectively prevent water retention.
[0021] Both the front part 4 and the rear part 6 of the sealing plug are provided with sealing plug positioning grooves 18 on their outer end faces, ensuring accurate installation and positioning.
[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
