Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a sealing structure for an ECU connector. Background Technology

[0002] With the development of automotive electrification, more and more structural components in automobiles are now driven by electric motors to meet the electric adjustment requirements of the corresponding structures. For example, the electric lifting of car windows uses a window regulator motor as a power source. The window is raised and lowered and stopped by the forward and reverse rotation and start and stop control of the window regulator motor to meet the usage requirements.

[0003] Furthermore, to enable modular production of automobiles and improve production efficiency, the electric drive system is typically equipped with an ECU connector to connect to the controller, ensuring a fast, convenient, and stable electrical connection. Additionally, for the safe and effective operation of the electric drive system, the ECU connector itself requires a sealed design to ensure that its internal electronic components and other structures are not exposed to air. Currently, commercially available ECU connectors typically include a base shell, a cover plate, and a corresponding circuit board structure. The base shell has a mounting cavity with an opening, through which the circuit board structure is installed. The cover plate is installed at the opening of the base shell and has a connector for subsequent wiring. A sealing strip is placed between the cover plate and the base shell to achieve a seal between them, ensuring the ECU connector's airtightness. While the above structure also achieves a seal, the sealing strip is usually arranged horizontally to the opening wall, i.e., perpendicular to the sealing surface, with the sealing edge of the strip abutting against the sealing surface to achieve a tight seal. However, in structures that use a plug-in sealing method, the arrangement direction of the sealing strip is consistent with its plugging direction. This means that when the sealing strip contacts the sealing surface and continues to be inserted and squeezed, factors such as the processing precision of the sealing strip itself, the direction of force at the moment of contact with the sealing surface, and friction can easily cause different parts of the sealing strip to compress in different directions. This results in the formation of pores at the intersection of the sealing strips compressed in different directions, affecting the sealing performance and leaving the possibility of water leakage, thus resulting in poor reliability. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention aims to provide a sealing structure for an ECU connector. This structure includes a semi-open gearbox and a reverse semi-open connector seat with a sealing strip. The sealing strip has a triangular cross-section, with one of its apexes forming the sealing edge. The triangular sealing edge of the sealing strip is inclined outwards from the opening. This design ensures that when the connector seat is inserted into the gearbox, the pre-designed inclination of the sealing edge allows for compression of the sealing strip in the same direction, preventing incomplete sealing due to different compression directions. This improves sealing reliability and guarantees sealing performance.

[0005] The specific technical solution is as follows:

[0006] A sealed structure for an ECU connector includes a gearbox and a connector housing, characterized in that both the gearbox and the connector housing are semi-open structures. The gearbox includes a front vertical wall, two side vertical walls, and a bottom wall. The two side vertical walls are located on either side of the front vertical wall, and the bottom wall is located below the front and side vertical walls and is interconnected. The connector housing includes a top wall and a rear vertical wall. The top wall is located above and connected to the rear vertical wall. When the connector housing is mounted on the gearbox, the top wall is located above the bottom wall and is connected to both the front and side vertical walls. The rear vertical wall is spaced apart. Arranged on the front vertical wall and located between the two side vertical walls, and connected to the rear vertical wall, the connector seat has an L-shaped mounting block on its inner side. One side of the L-shaped mounting block is fixed to the top wall and the rear vertical wall. The outer side of the L-shaped mounting block forms a first sealing surface. A sealing strip is arranged around the first sealing surface. The sealing part of the sealing strip has a triangular cross-section, and the side with the sharp corner away from the first sealing surface is the sealing edge. The sealing edge is arranged at an inclined angle to the first sealing surface, and the inclined direction of the sealing edge is towards the top wall and the rear vertical wall.

[0007] In the sealing structure of the aforementioned ECU connector, the three surfaces of the first sealing surface on the top wall correspond to the front vertical wall and the two side vertical walls respectively. Furthermore, the sealing strips on the parts corresponding to the two side vertical walls are arranged obliquely on the first sealing surface, and the oblique direction of the sealing strips along the direction from the front vertical wall to the rear vertical wall is from the top wall to the bottom wall.

[0008] In the sealing structure of the aforementioned ECU connector, several sealing parts are arranged side by side on the same sealing strip, and the several sealing parts are arranged at intervals.

[0009] In the aforementioned sealing structure of an ECU connector, both sides of the rear vertical wall are provided with locking feet, and the outer walls of both sides of the vertical wall are provided with locking blocks corresponding to the locking feet.

[0010] In the sealing structure of the aforementioned ECU connector, a first groove is provided on the outer wall of each side vertical wall in a direction parallel to the top or bottom wall, and the locking foot is slidably connected to the first groove on the corresponding side.

[0011] In the sealing structure of the aforementioned ECU connector, a second sliding groove is provided on the inner wall of each side vertical wall in a direction parallel to the top or bottom wall, and an insertion block corresponding to each of the two second sliding grooves is provided on both sides of the L-shaped mounting block.

[0012] In the sealing structure of the aforementioned ECU connector, the top of the front vertical wall is provided with a plurality of upper retaining edges extending toward the rear vertical wall, the plurality of upper retaining edges being arranged at intervals, the top wall is provided with a plurality of mating retaining edges, the plurality of mating retaining edges being arranged at intervals, and when the connector seat is installed on the gearbox, the plurality of upper retaining edges and the plurality of mating retaining edges are alternately engaged, and the front vertical wall is provided with a first clearance notch corresponding to the mating retaining edges, and the top wall is provided with a second clearance notch corresponding to the upper retaining edges.

[0013] In the aforementioned sealing structure of an ECU connector, a first aligning protrusion is provided on the upper part of the inner wall of each side vertical wall. The first aligning protrusion is located on the side of the side vertical wall near the rear vertical wall. Simultaneously, the lowest point of the end of the sealing strip that is inclined on the first sealing surface near the front vertical wall is higher than the highest point of the end that is inclined on the rear vertical wall. During installation, when the connector seat initially contacts the gearbox, the first aligning protrusion is located below the lowest point of the end of the sealing strip that is inclined on the first sealing surface near the front vertical wall. When the connector seat is installed in place on the gearbox, the first aligning protrusion is located above the highest point of the end of the sealing strip that is inclined on the first sealing surface near the rear vertical wall.

[0014] In the sealing structure of the aforementioned ECU connector, a second aligning protrusion is provided on the inner wall of the bottom wall and on the side near the rear vertical wall. When the connector seat is installed in place on the gearbox, the second aligning protrusion is located on the side of the sealing strip near the rear vertical wall.

[0015] The aforementioned sealing structure for an ECU connector further includes a third consolidation structure. This third consolidation structure comprises a slide cylinder, a U-shaped consolidation frame, a third consolidation protrusion, a trigger block, a spring, and a lifting spring. The slide cylinder is disposed on the outer wall of the front vertical wall. The U-shaped consolidation frame has its opening facing downwards and one end inserted into the slide cylinder. The other end of the U-shaped consolidation frame is tightly fitted against the inner wall of the front vertical wall and has a third consolidation protrusion at its end. The lifting spring is installed inside the slide cylinder, with its upper end abutting against the end of the U-shaped consolidation frame inserted into the slide cylinder. A trigger hole is provided on the side wall of the slide cylinder. The trigger block is installed on the end of the U-shaped consolidation frame inserted into the slide cylinder and remains in contact with the top wall when not in contact with the U-shaped consolidation frame. Inside the hole, the inner cavity of the slide tube is provided with a clearance slide on the side opposite to the U-shaped sorting frame. When the trigger block is dislodged from the trigger hole, the end of the U-shaped sorting frame inserted into the slide tube moves into the clearance slide. At the same time, a spring is provided on the end of the U-shaped sorting frame inserted into the slide tube, and one end of the spring extends into the clearance slide. Furthermore, a limit cap is provided at the upper opening of the slide tube. The limit cap is sleeved on the outside of the end of the U-shaped sorting frame inserted into the slide tube. At the same time, when the top wall is not in contact with the U-shaped sorting frame, the third sorting protrusion is located below the sealing strip. After the top wall contacts the U-shaped sorting frame, the end of the U-shaped sorting frame with the third sorting protrusion moves up to the top of the sealing strip.

[0016] The positive effects of the above technical solution are:

[0017] The sealing structure of the aforementioned ECU connector features a semi-open gearbox and connector housing. An L-shaped mounting block is installed on the connector housing, and a sealing strip is mounted on the L-shaped mounting block. The sealing strip has a triangular cross-section, with one of its sharp angles forming a sealing edge. The sealing edge of the sealing strip is angled outwards towards the connector housing, ensuring horizontal insertion when the connector housing is pushed horizontally towards the gearbox. Furthermore, because the sealing edges of the sealing strip are all angled outwards towards the connector housing, a predetermined angle ensures that when the sealing strip is compressed, the sealing edges deform in the same direction. This effectively avoids the problem of incomplete sealing caused by different compression directions of the sealing edges, ensuring sealing reliability and resulting in better sealing and higher safety for the ECU connector.

[0024] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 5 The technical solutions provided by this invention are described in detail, but the following content is not intended to limit this invention.

[0025] Figure 1 This is a structural diagram of an embodiment of the sealing structure of an ECU connector according to the present invention; Figure 2 This is a structural diagram of a gearbox with a sealing structure for an ECU connector according to the present invention; Figure 3 This is a structural diagram of a connector holder with a sealing structure for an ECU connector according to the present invention. Figure 1 , Figure 2 as well as Figure 3 As shown, the sealing structure of the ECU connector provided in this embodiment includes a gearbox 1 and a connector seat 2 for sealing between the gearbox 1 and the connector seat 2, ensuring the sealing performance of the ECU connector.

[0026] Specifically, both the gearbox 1 and the connector seat 2 are semi-open structures. The gearbox 1 has an L-shaped opening, meaning both sides are open. The connector seat 2 is arranged in an "L" shape. The installation of the connector seat 2 on the gearbox 1 forms a relatively sealed cuboid structure, providing a sealed, safe, and reliable installation space for structures such as the control circuit board. It also facilitates the insertion and installation of the connector seat 2 on the gearbox 1, meeting the installation requirements of structures such as the control circuit board arranged on a single plane. The gearbox 1 also includes a front vertical wall 11, two side vertical walls 12, and a bottom wall 13. From an overall perspective, the two side vertical walls 12 are located on either side of the front vertical wall 11, and the bottom wall 13 is located below the front vertical wall 11 and the two side vertical walls 12 and are interconnected, forming four interactive rectangular surfaces. Meanwhile, the connector seat 2 includes a top wall 21 and a rear vertical wall 22. Viewed as a whole, the top wall 21 is positioned above and connected to the rear vertical wall 22, forming an "L"-shaped structure and two interacting surfaces of a rectangular structure. Furthermore, when the connector seat 2 is installed on the gearbox 1, the top wall 21 is located above the bottom wall 13 and connected to the front vertical wall 11 and the two side vertical walls 12 respectively. The rear vertical wall 22 is spaced apart from the front vertical wall 11 and located between the two side vertical walls 12, and is connected to the two side vertical walls 12 and the bottom wall 13. Thus, the four interacting surfaces of the gearbox 1 and the two interacting surfaces of the connector seat 2 form a complete rectangular structure with six surfaces, thereby meeting the requirements for forming a sealing structure. Meanwhile, an L-shaped mounting block 3 is provided on the inner side of the connector seat 2. After the connector seat 2 is installed on the gearbox 1, the L-shaped mounting block 3 is located inside the gearbox 1. One side of the L-shaped mounting block 3 is fixed to the top wall 21 and the rear vertical wall 22, so that the top wall 21 and the rear vertical wall 22 of the connector seat 2 have corresponding L-shaped mounting block 3 structures. At the same time, a first sealing surface 31 is formed on the outer wall of the L-shaped mounting block 3. A sealing strip 4 is provided around the first sealing surface 31. When the connector seat 2 is installed on the gearbox 1, since the L-shaped mounting block 3 is located inside the gearbox 1, the sealing strip 4 on the L-shaped mounting block 3 can directly abut against the inner wall of the gearbox 1. That is, the sealing between the connector seat 2 and the gearbox 1 is achieved by the sealing strip 4. In addition, the cross-section of the sealing part 41 of the sealing strip 4 is arranged in a triangle and the side where the sharp corner away from the first sealing surface 31 is located is selected as the sealing edge 411. During sealing, the sealing edge 411 contacts the inner wall of the gearbox 1 to achieve sealing. As the connector seat 2 is inserted into the gearbox 1, the sealing edge 411 is squeezed, thereby improving the effectiveness and reliability of the sealing.In addition, the sealing edge 411 is arranged at an inclined angle to the first sealing surface 31, and the inclined direction of the sealing edge 411 is arranged towards the top wall 21 and the rear vertical wall 22. That is, the sealing edge 411 itself has a preset inclined angle, so that when the connector seat 2 is inserted into the gearbox 1, the sealing edge 411 can bend towards the preset inclined angle during the compression process, thereby maintaining the consistency of the inclination of the sealing edge 411, avoiding the problem of the existing sealing edge 411 randomly tilting and sealing, which causes the formation of gaps between different inclined parts, improving the effectiveness and reliability of the seal, and making the structural design more reasonable.

[0027] More specifically, the first sealing surface 31 of the L-shaped mounting block 3, and the three surfaces located on the corresponding top wall 21, correspond to the front vertical wall 11 and the two side vertical walls 12 of the gearbox 1, respectively. At this time, the portion of the sealing strip 4 on the first sealing surface 31 corresponding to the two side walls is arranged obliquely on the first sealing surface 31. This results in the middle portion of the sealing strip 4 used to connect its horizontal and vertical sections being also obliquely arranged in the direction along which the connector seat 2 is inserted into the gearbox 1, thus forming an oblique angle with the insertion direction. Furthermore, along the direction from the front vertical wall 11 to the rear vertical wall 22, the oblique direction of the sealing strip 4 is from the top wall 21 to the bottom wall 13. This ensures that when the connector seat 2 is inserted into the gearbox 1, the frictional force of the inner wall of the gearbox 1 on the sealing edge 411 of the sealing strip 4 is an upward oblique force, better conforming to the structural requirement of the sealing edge 411 of the sealing strip 4 tilting outwards. This allows the sealing edge 411 of the sealing strip 4 to bend more smoothly in the same direction, ensuring sealing performance.

[0028] More specifically, several sealing parts 41 are arranged side by side on the same sealing strip 4. At this time, the several sealing parts 41 are arranged at intervals, and the arrangement direction of each sealing part 41 is consistent with the arrangement direction of the sealing strip 4 on which it is located. Furthermore, the shapes of the several sealing parts 41 are all the same, so that the sealing strip 4 and the inner wall of the gearbox 1 are sealed by multiple sealing parts 41, and the sealing effect of each sealing part 41 is the same, further improving the sealing performance.

[0029] More specifically, locking feet 23 are provided on both sides of the rear vertical wall 22, and locking blocks 14 corresponding to the locking feet 23 are provided on the outer walls of both vertical walls 12. At this time, one locking foot 23 corresponds to one locking block 14, so that when the connector seat 2 is inserted into the gearbox 1, the locking foot 23 can cooperate with the corresponding locking block 14 to realize the locking connection between the connector seat 2 and the gearbox 1, making disassembly and assembly more convenient.

[0030] More specifically, a first groove 15 is provided on the outer wall of each vertical wall 12 in a direction parallel to the top wall 21 or the bottom wall 13. The locking foot 23 is slidably connected to the first groove 15 on the corresponding side. That is, when the connector seat 2 is installed on the gearbox 1, the connection can be achieved by sliding the locking foot 23 in the first groove 15. This provides guidance for maintaining the installation direction when the plug is tightened, and also provides conditions for maintaining the stability of the fit after subsequent installation.

[0031] More specifically, a second sliding groove 16 is provided on the inner wall of each side vertical wall 12 in a direction parallel to the top wall 21 or bottom wall 13. At the same time, a plug 24 corresponding to the two second sliding grooves 16 is provided on both sides of the L-shaped mounting block 3. That is, when the connector seat 2 is inserted into the gearbox 1, the installation guide can be achieved by sliding the plug 24 in the corresponding second sliding groove 16, so that the parts can be accurately matched when they are engaged, improving the accuracy of the installation direction and facilitating disassembly and assembly.

[0032] More specifically, the top of the front vertical wall 11 is provided with several upper retaining edges 111 extending towards the rear vertical wall 22. These upper retaining edges 111 are spaced apart, allowing for gaps between them. Simultaneously, the upper retaining edges 111 form limiting edges at the top of the front vertical wall 11, providing conditions for subsequently restricting the upward movement of the top wall 21. Additionally, the top wall 21 is provided with several mating retaining edges 211, which are spaced apart to accommodate the arrangement requirements of the upper retaining edges 111. Furthermore, when the connector seat 2 is installed on the gearbox 1, the upper retaining edges 111 and the mating retaining edges 211 alternately engage, creating multiple alternating connection points between the gearbox 1 and the connector seat 2, improving connection strength and ensuring installation accuracy. Furthermore, a first clearance notch 112 corresponding to the mating edge 211 is provided on the front vertical wall 11, and a second clearance notch 212 corresponding to the upper clamping edge 111 is provided on the top wall 21. This allows the upper clamping edge 111 to extend into the first clearance notch 112 to restrict the top wall 21 from moving upward relative to the gearbox 1 when the connector seat 2 and the gearbox 1 are installed together. At the same time, by extending the mating edge 211 into the second clearance notch 212 to restrict the top wall 21 from moving downward relative to the gearbox 1, the gearbox 1 and the connector seat 2 can be stably positioned, improving the connection stability between the two and meeting the usage requirements of plugging and unplugging connectors.

[0033] Figure 4 This is a structural diagram of a gearbox with a first tidying protrusion, a second tidying protrusion, and a third tidying structure, according to a preferred embodiment of the present invention. Figures 1 to 4As shown, a first tidying protrusion 17 is provided on the upper part of the inner wall of each side vertical wall 12. At this time, the first tidying protrusion 17 is set on the side of the side vertical wall 12 near the rear vertical wall 22, so that when the connector seat 2 is installed on the gearbox 1, the sealing strip 4 can contact the first tidying protrusion 17 at the first time, which provides the conditions for sorting the compression direction of the sealing strip 4 through the first tidying protrusion 17 during the subsequent installation process. Meanwhile, when the sealing strip 4 installed on the first sealing surface 31 is installed, the lowest point of the end of the sealing strip 4 that is inclined on the first sealing surface 31, near the front vertical wall 11, is higher than the highest point of the end that is inclined on the rear vertical wall 22. That is, the distance between the highest point of one end and the lowest point of the other end of the part of the sealing strip 4 that is inclined on the side wall of the first sealing surface 31 can be greater than the width of the sealing strip 4. This allows the first sorting protrusion 17 to move from below the sealing strip 4 to above the sealing strip 4 as the insertion depth of the connector seat 2 on the gearbox 1 gradually increases when the sealing strip 4 is sorted by the first sorting protrusion 17, thereby sorting the sealing strip 4. Meanwhile, during installation, when the connector seat 2 initially contacts the gearbox 1, the first tidying protrusion 17 is located below the lowest point of the end of the sealing strip 4 that is inclined on the first sealing surface 31, near the front vertical wall 11. Furthermore, when the connector seat 2 is installed in place on the gearbox 1, the first tidying protrusion 17 is located above the highest point of the end of the sealing strip 4 that is inclined on the first sealing surface 31, near the rear vertical wall 22. This allows the first tidying protrusion 17 to tidy up the sealing edge 411 of the sealing strip 4 during installation, causing the sealing edge 411 to bend and deform towards the same side, thus ensuring sealing performance. In addition, it also ensures that the first tidying protrusion 17 is located on the outside of the sealing strip 4 after installation, without interfering with the sealing of the sealing strip 4, resulting in a more reasonable structural design.

[0034] More specifically, a second tidying protrusion 18 is provided on the inner wall of the bottom wall 13, near the rear vertical wall 22. When the connector seat 2 is inserted into the gearbox 1, the sealing strip 4 on the side of the first sealing surface 31 corresponding to the bottom wall 13 can immediately contact the second tidying protrusion 18. As the insertion depth of the connector seat 2 increases, it passes through the second tidying protrusion 18. The second tidying protrusion 18 tidies up the sealing edge 411 of the sealing strip 4 corresponding to the bottom wall 13, so that the sealing strip 4 corresponding to the bottom wall 13 can also be squeezed and bent towards the same side, ensuring sealing performance. In addition, when the gearbox 1 is installed in place, the second tidying protrusion 18 is located on the side of the sealing strip 4 near the rear vertical wall 22, so that the sealing strip 4 after sealing is not affected by the second tidying protrusion 18, ensuring the sealing effect.

[0035] Figure 5 This is a cross-sectional view of the third finishing structure according to a preferred embodiment of the present invention. Figures 1 to 5As shown, a third sorting structure 5 is also provided on the gearbox 1. The third sorting structure 5 is used to sort the sealing edge 411 of the sealing strip 4 relative to the front vertical wall 11 to ensure sealing performance. At this time, the third sorting structure 5 includes a slide cylinder 51, a U-shaped sorting frame 52, a third sorting protrusion 57, a trigger block 53, a spring 54, and a lifting spring 55. During installation, the slide cylinder 51 is set on the outer wall of the front vertical wall 11. Preferably, the slide cylinder 51 and the front vertical wall 11 are integrally injection molded structures, which improves the reliability of the connection of the slide cylinder 51. In addition, the opening of the U-shaped sorting frame 52 is arranged downward and one end is inserted into the slide cylinder 51. At the same time, the other end of the U-shaped sorting frame 52 is arranged close to the inner wall of the front vertical wall 11 and the end is provided with the third sorting protrusion 57. This allows the third sorting protrusion 57 to move up and down with the U-shaped sorting frame 52 in the gearbox 1, providing conditions for subsequent sorting of the sealing edge 411 of the sealing strip 4 by the third sorting protrusion 57. In addition, the slide cylinder 51 provides a sliding path for the up-and-down movement of the U-shaped sorting frame 52, maintaining the stability of the U-shaped sorting frame 52 during movement. Furthermore, a lifting spring 55 is installed inside the slide cylinder 51, with its upper end abutting against the end of the U-shaped sorting frame 52 inserted into the slide cylinder 51. The lifting spring 55 provides power for the upward movement of the U-shaped sorting frame 52. That is, when the third sorting protrusion 57 is used to comb the sealing edge 411 of the sealing strip 4, the lifting spring 55 drives the third sorting protrusion 57 to move relative to the sealing strip 4, thereby meeting the combing requirements. In addition, a trigger hole 511 is provided on the side wall of the slide cylinder 51. At the same time, a trigger block 53 is installed on one end of the U-shaped sorting frame 52 inserted into the slide cylinder 51 and is always located in the trigger hole 511 when the top wall 21 does not contact the U-shaped sorting frame 52. The U-shaped sorting frame 52 is temporarily positioned by the mutual engagement of the trigger block 53 and the trigger hole 511, which restricts the movement of the U-shaped sorting frame 52. This allows the end of the U-shaped sorting frame 52 with the third sorting protrusion 57 to be kept in the gearbox 1 when the connector seat 2 is not installed on the gearbox 1, providing conditions for subsequent upward movement.Meanwhile, a clearance slide 512 is also provided in the inner cavity of the slide cylinder 51 on the side opposite to the U-shaped sorting frame 52. The arrangement direction of the clearance slide 512 is consistent with the upward movement direction of the U-shaped sorting frame 52. Furthermore, when the trigger block 53 disengages from the trigger hole 511, the end of the U-shaped sorting frame 52 inserted into the slide cylinder 51 moves into the clearance slide 512. That is, when the connector seat 2 is installed on the gearbox 1 and the top wall 21 approaches the forward vertical wall 11, if the top wall 21 contacts and pushes the U-shaped sorting frame 52, it can... This causes the U-shaped sorting frame 52 to move toward the side of the avoidance slide 512, thereby causing the trigger block 53 on the U-shaped sorting frame 52 to disengage from the trigger hole 511. This causes the U-shaped sorting frame 52 to move upward under the action of the lifting spring 55, thereby driving the third sorting protrusion 57 to move upward. The third sorting protrusion 57 then combs the sealing edge 411 of the sealing strip 4, which has just moved over, upward, so that the sealing edge 411 of the sealing strip 4 can be squeezed in the same direction, ensuring the sealing performance. Meanwhile, a spring clip 54 is provided on the end of the U-shaped organizer 52 that is inserted into the slide cylinder 51. When one end of the spring clip 54 is inserted into the clearance slide 512, the U-shaped organizer 52 can be held in place by the spring clip 54 when it is not moving, thereby keeping the trigger block 53 locked in the trigger hole 511. When the U-shaped organizer 52 is pushed by the top wall 21, the deformation of the spring clip 54 can adapt to meet the need for the trigger block 53 to come out of the trigger hole 511. In addition, a limiting cap 56 is provided at the upper opening of the slide cylinder 51. When the limiting cap 56 is sleeved on the end of the U-shaped organizer 52 that is inserted into the slide cylinder 51, the limiting cap 56 can limit the upper opening of the slide cylinder 51, preventing the U-shaped organizer 52 from accidentally coming out of the slide cylinder 51. Preferably, the limiting cap 56 and the outer wall of the slide cylinder 51 are snap-fitted together, which facilitates the assembly and disassembly of the limiting cap 56 and the U-shaped sorting frame 52 on the slide cylinder 51. Simultaneously, when the top wall 21 is not in contact with the U-shaped sorting frame 52, the third sorting protrusion 57 is located below the sealing strip 4. After the top wall 21 contacts the U-shaped sorting frame 52, the end of the U-shaped sorting frame 52 with the third sorting protrusion 57 moves upward to above the sealing strip 4. This ensures that the sealing edge 411 of the sealing strip 4 is properly combed, and that the sealing strip 4 is no longer affected by the third sorting structure 5 after sealing, thus ensuring a good sealing effect.

[0036] The sealing structure of the ECU connector provided in this embodiment includes a gearbox 1 and a connector seat 2. By setting the gearbox 1 and connector seat 2 as a semi-open structure, the connector seat 2 is inserted into the semi-open part of the gearbox 1. At the same time, an L-shaped mounting block 3 with a sealing strip 4 is provided on the connector seat 2. The sealing part 41 of the sealing strip 4 has a triangular cross-section, and the side where the sharp corner is used to contact the inner wall of the gearbox 1 forms a sealing edge 411. Meanwhile, the sealing edge 411 of the sealing strip 4 is inclined towards the outside of the connector seat 2, so that when the connector seat 2 is inserted into the gearbox 1, the connector seat 2 and the gearbox 1 move horizontally relative to each other. The sealing edges 411 of the sealing strip 4 are all inclined towards the outside of the connector seat 2, so that when the sealing edges 411 of the sealing strip 4 contact the inner wall of the gearbox 1 and are compressed, the sealing edges 411 can be compressed and deformed in the same direction, thereby effectively avoiding the problem of poor sealing caused by different compression directions of the sealing edges 411, resulting in better sealing performance and higher safety in use.
