Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle electric drive controllers, specifically relating to a shock-resistant connector structure for a vehicle electric drive controller. Background Technology

[0002] During vehicle operation, due to the complexity of road conditions (such as bumps, undulations, potholes, etc.), the vehicle will inevitably vibrate. This vibration will be directly transmitted to the vehicle's electric drive controller, causing it to vibrate accordingly.

[0003] As a core component controlling vehicle power output and driving status, the stability of the vehicle's electric drive controller directly affects the normal operation and driving safety of the vehicle. Currently, most existing vehicle electric drive controllers use a snap-fit ​​connection method for their connectors. While this method can prevent connectors from falling off to some extent and meet basic connection requirements, it has significant limitations.

[0004] Due to the plug-in structure of connectors, a certain gap inevitably exists between the male and female connectors. During prolonged vehicle vibration, the male and female connectors will wobble and rub against each other within this gap. As usage time increases, this wobble and friction will wear down the male and female connectors, causing their contact to become less tight. This not only affects the stable transmission of electrical signals, potentially leading to control delays and signal interruptions in the vehicle's electric drive controller, but in severe cases, it can even affect the vehicle's power output and driving safety. Furthermore, accelerated wear further reduces the structural strength of the connector, making its vibration resistance increasingly poor and unable to meet the long-term usage requirements of vehicles under complex road conditions, posing a potential risk to the normal operation of the vehicle. Utility Model Content

[0005] The purpose of this invention is to provide a vibration-resistant connector structure for a vehicle electric drive controller, in order to solve the problems existing in the background art.

[0006] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows: An anti-vibration connector structure for a vehicle electric drive controller includes a female connector and a male connector. A filling component is sleeved on the outer side of the pins of the male connector. The filling component is used to fill the gap between the male connector and the female connector, and includes: An isolation sleeve is fitted onto the pins of the male plug, and the outer side of the isolation sleeve is provided with external threads; A connecting ring is fitted onto the outside of the isolation sleeve; Multiple arc-shaped pieces are fixedly connected to the end of the connecting ring away from the male plug-in head along the length direction of the isolation sleeve. A gap is provided between each adjacent arc-shaped piece so that the arc-shaped pieces form a hollow sleeve, and the radius of the arc-shaped pieces gradually decreases from the male plug-in head to the female plug-in head. A threaded sleeve is fitted onto the isolation sleeve via the external thread, and the threaded sleeve is located between the hollow sleeve and the isolation sleeve.

[0007] Optionally, the threaded sleeve has a rotating ring on the outer side of one end near the male plug-in connector, and the diameter of the rotating ring is larger than the diameter of the male plug-in connector.

[0008] Optionally, the anti-vibration connector structure of the vehicle electric drive controller further includes a limiting component; A limiting groove is provided on the outer side of the rotating ring; The limiting component includes: A support piece is disposed on the opening of the plug-in female head along the opening of the plug-in female head; A card is disposed at the end of the support piece away from the plug-in female head, and the card is perpendicular to the axis of the plug-in female head so that the card can be snapped into the limiting groove.

[0009] Optionally, the card and the rotating ring are both inclined on opposite sides.

[0010] Optionally, a connecting groove is provided on the inner side of each of the arc-shaped pieces away from the male plug-in connector; The outer side of the isolation sleeve is provided with a retaining ring that is movable inside the connecting groove.

[0011] Optionally, the isolation sleeve, connecting ring, and arc-shaped piece are all made of insulating material.

[0012] The beneficial effects of this utility model are: By using the filling components (isolation sleeve, connecting ring, arc-shaped piece, threaded sleeve), the gap between the male and female plug can be dynamically filled: the threaded sleeve pushes the arc-shaped piece to expand radially and fit tightly against the inner wall of the female plug, eliminating the relative wobbling space between the two, reducing mutual wear caused by long-term vibration, fundamentally improving the shock resistance stability of the connector, adapting to the needs of vehicles in complex road conditions, and increasing the overall service life of the connector.

Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] like Figure 1-4 As shown, a vibration-resistant connector structure for a vehicle electric drive controller includes a female connector 12 and a male connector 13. The female connector 12 is mounted on the vehicle electric drive controller 11. A filling component is sleeved on the outer side of the pins of the male connector 13. The filling component is used to fill the gap between the male connector 13 and the female connector 12, and includes: An isolation sleeve 21 is fitted onto the pin of the male plug 13, and the outer side of the isolation sleeve 21 is provided with an external thread 22; Connecting ring 23 is sleeved on the outside of isolation sleeve 21; Multiple arc-shaped pieces 24 are fixedly connected to the end of the connecting ring 23 away from the male plug-in head 13 along the length direction of the isolation sleeve 21. There are gaps between each adjacent arc-shaped piece 24 so that each arc-shaped piece 24 forms a hollow sleeve, and the radius of the arc-shaped piece 24 gradually decreases from the male plug-in head 13 to the female plug-in head 12. The threaded sleeve 25 is fitted onto the isolation sleeve 21 through the external thread 22, and the threaded sleeve 25 is located between the hollow sleeve and the isolation sleeve 21.

[0017] The female connector 12 is mounted on the vehicle electric drive controller 11 as the fixed end of the connector, used to mate with the male connector 13 to achieve electrical connection, and is one of the key interfaces for electrical signal transmission. Its internal structure is adapted to the pins and filling components of the male connector 13, providing a stable space for both and ensuring accurate alignment during connection.

[0018] The male connector 13, as the movable end of the connector, has pins used to connect with the internal contacts of the female connector 12 to transmit electrical signals. The mating of the male connector 13 and the female connector 12 is the basis for establishing a connection between the vehicle's electric drive controller and external components (such as motors, sensors, etc.).

[0019] The filling component is fitted onto the outside of the pins of the male connector 13. Its core function is to fill the gap between the male connector 13 and the female connector 12, thereby reducing relative friction caused by vibration by eliminating the gap. Specifically, it includes the following components: The isolation sleeve 21 is tightly fitted onto the pin of the male connector 13. On the one hand, it protects the pin and prevents it from being damaged by direct friction with other components. On the other hand, the external thread 22 on its outer side provides a foundation for the threaded connection of the threaded sleeve 25, ensuring that the threaded sleeve 25 can move axially along the isolation sleeve 21. At the same time, the isolation sleeve 21 isolates the pin from external components, reducing interference.

[0020] The connecting ring 23 is sleeved on the outside of the isolation sleeve 21, serving as a fixed carrier for the arc-shaped pieces 24 and connecting multiple arc-shaped pieces 24 into a whole. Its cooperation with the isolation sleeve 21 ensures the positional stability of the arc-shaped pieces 24 in the radial direction and provides a supporting basis for the deformation of the arc-shaped pieces 24.

[0021] Multiple arc-shaped pieces 24 are fixed along the length of the isolation sleeve 21 at the end of the connecting ring 23 away from the male plug-in head 13. The gaps between adjacent arc-shaped pieces 24 form a hollow sleeve, and the radius of the arc-shaped pieces 24 gradually decreases from the male plug-in head 13 to the female plug-in head 12 (i.e., it is "tightening"). This structural design gives it a certain radial deformation capability: when subjected to external force, the arc-shaped pieces 24 can expand outward to fill the gap between the male plug-in head 13 and the female plug-in head 12; under normal conditions, they remain in a closed state, facilitating the insertion of the male plug-in head 13 and the female plug-in head 12.

[0022] The threaded sleeve 25 is fitted onto the isolation sleeve 21 via the external thread 22, and is located between the hollowed-out sleeve composed of the arc-shaped piece 24 and the isolation sleeve 21. Its core function is to compress the arc-shaped piece 24 through axial movement: when the threaded sleeve 25 rotates and moves along the external thread 22 towards the arc-shaped piece 24, since the arc-shaped piece 24 is constricted, the inner wall of the threaded sleeve 25 will generate a radially outward thrust on the arc-shaped piece 24, forcing the arc-shaped piece 24 to expand outward and tightly fit the inner wall of the plug-in female head 12, thereby filling the gap between the two; conversely, when the threaded sleeve 25 moves in the opposite direction, the arc-shaped piece 24 contracts under its own elasticity, facilitating the insertion and removal of the connector.

[0023] Through the above structure, the expansion degree of the arc-shaped piece 24 can be adjusted according to the actual gap size to achieve dynamic filling of the gap between the male plug 13 and the female plug 12, fundamentally reducing the relative shaking and friction between the two during vibration, and significantly improving the shock resistance and service life of the connector.

[0024] Furthermore, a rotating ring 26 is provided on the outer side of the end of the threaded sleeve 25 near the male plug-in head 13, and the diameter of the rotating ring 26 is larger than the diameter of the male plug-in head 13.

[0025] The rotating ring 26 is located on the outer side of the threaded sleeve 25 near the male connector 13. Its diameter is larger than that of the male connector 13. It serves as the operating carrier and limiting structure for the threaded sleeve 25. Since the threaded sleeve 25 is connected to the isolation sleeve 21 via the external thread 22, axial movement is achieved through rotation to compress the arc-shaped piece 24. The rotating ring 26 increases the operating contact area, allowing the operator to directly hold or use tools to rotate it, thereby causing the threaded sleeve 25 to rotate synchronously. This is more labor-saving and convenient than directly operating the smaller-diameter threaded sleeve 25, improving the efficiency of connector installation and debugging.

[0026] Its diameter is larger than that of the male plug 13, which can play an axial limiting role during the insertion of the male plug 13 and the female plug 12: when the male plug 13 is inserted into the female plug 12 to the preset position, the rotating ring 26 will abut against the end or surrounding structure of the male plug 13, so as to avoid the male plug 13 being over-inserted and causing damage to the pin or filling component, while ensuring that the mating position of the arc-shaped piece 24 and the female plug 12 is accurate, thus ensuring the gap filling effect.

[0027] Furthermore, the vibration-resistant connector structure of the vehicle electric drive controller also includes a limiting component; A limiting groove 27 is provided on the outer side of the rotating ring 26; The limit components include: The support piece 31 is disposed along the opening of the plug-in female head 12 and facing the opening of the plug-in female head 12; Card 32 is disposed at the end of support piece 31 away from plug female head 12, and card 32 is perpendicular to the axis of plug female head 12 so that card 32 can be snapped into limit groove 27.

[0028] The limiting groove 27 is located on the outside of the rotating ring 26 and serves as the engagement point for the card 32. Its shape and size are adapted to the structure of the card 32, providing space for a tight fit between the two. When the card 32 is engaged in the limiting groove 27, the rotating ring 26 can be prevented from rotating by mechanical limiting, thereby restricting the axial movement of the threaded sleeve 25 and ensuring the stability of the expansion state of the arc-shaped piece 24.

[0029] The support piece 31 is positioned at the opening of the female connector 12, serving as a fixed support structure for the card 32. Its length and angle design ensure that the card 32 can be precisely aligned with the limiting groove 27 of the rotating ring 26, while also possessing a certain degree of elastic deformation capability. During the insertion or separation of the male connector 13 and the female connector 12, the support piece 31 can be slightly bent under external force to prevent rigid collision between the card 32 and the rotating ring 26. When the card 32 is inserted into the limiting groove 27, the elastic restoring force of the support piece 31 enhances the tightness of the fit between the card 32 and the limiting groove 27, improving the limiting effect.

[0030] The clip 32 is positioned at the end of the support piece 31 furthest from the plug-in female head 12 and extends perpendicularly to the axis of the plug-in female head 12. Its core function is to achieve locking through engagement with the limiting groove 27. When the threaded sleeve 25 is adjusted to the appropriate position (the arc-shaped piece 24 fully fills the gap), the clip 32 is embedded in the limiting groove 27, directly restricting the rotational freedom of the rotating ring 26. This prevents the threaded sleeve 25 from moving in the opposite direction due to loosening during vehicle vibration and avoids the reappearance of gaps caused by the contraction of the arc-shaped piece 24. Furthermore, its extension direction perpendicular to the axis ensures that the engagement direction is perpendicular to the rotational tangent direction of the rotating ring 26, effectively resisting rotational forces and improving the reliability of locking.

[0031] By cooperating with the limiting component and the limiting groove 27, the position of the threaded sleeve 25 can be firmly fixed to prevent it from shifting during long-term vehicle vibration. This ensures that the filling component continuously and stably fills the gap between the male plug 13 and the female plug 12, further enhancing the seismic performance and structural stability of the connector structure.

[0032] Furthermore, the opposite sides of card 32 and rotating ring 26 are both inclined.

[0033] During the insertion of the male connector 13 into the female connector 12, the rotating ring 26 gradually approaches the card 32. Since both sides are inclined surfaces, a smooth guiding structure is formed upon contact. The inclined surface of the rotating ring 26 can slide along the inclined surface of the card 32. Through the component force of the inclined surface, the support piece 31 is slightly deformed away from the rotating ring 26, thus allowing the card 32 to naturally avoid the outer periphery of the rotating ring 26, preventing rigid collision or jamming. This design significantly reduces resistance during the insertion process, ensuring that the male connector 13 and the female connector 12 can smoothly align.

[0034] Furthermore, a connecting groove 28 is provided on the inner side of each arc-shaped piece 24 away from the plug-in male head 13; The outer side of the isolation sleeve 21 is provided with a retaining ring 29 that is movable inside the connecting groove 28.

[0035] The connecting groove 28 is located on the inner side of each arc-shaped piece 24, away from the male plug-in head 13. Its groove structure provides the retaining ring 29 with a space for movement and a limiting track. Since the arc-shaped piece 24 needs to expand outward under the action of external force (the thrust of the threaded sleeve 25) to fill the gap, the setting of the connecting groove 28, through its cooperation with the retaining ring 29, limits the excessive deformation or displacement of the arc-shaped piece 24, ensuring that its expansion direction is always radially outward, and avoiding the arc-shaped piece 24 from tilting or breaking due to uneven force.

[0036] The retaining ring 29 is located on the outside of the isolation sleeve 21 and is movably positioned inside the connecting groove 28. Its core function is to form a radial constraint on the arc-shaped piece 24 through sliding engagement with the connecting groove 28: when the arc-shaped piece 24 expands under the action of external force, the connecting groove 28 will slide along the outer circumference of the retaining ring 29. The annular structure of the retaining ring 29 can provide uniform support force for the arc-shaped piece 24, preventing a single arc-shaped piece 24 from over-opening due to excessive force; when the external force disappears (the threaded sleeve 25 moves in the opposite direction), the engagement between the retaining ring 29 and the connecting groove 28 can guide the arc-shaped piece 24 to contract uniformly, avoiding jamming or poor repositioning due to uneven deformation.

[0037] In addition, the cooperation between the retaining ring 29 and the connecting groove 28 can enhance the connection stability between the arc-shaped piece 24 and the isolation sleeve 21, prevent the connection between the arc-shaped piece 24 and the connecting ring 23 from loosening or fatigue damage during long-term vibration, further extend the service life of the filling component, ensure its continuous and stable gap filling function, and improve the shock resistance of the connector.

[0038] Furthermore, the isolation sleeve 21, the connecting ring 23, and the arc-shaped piece 24 are all made of insulating material.

[0039] The connectors of the vehicle electric drive controller are used to transmit electrical signals or power. The pins of the male connector 13 and the internal contacts of the female connector 12 are both conductive components. The isolation sleeve 21 is directly fitted on the outside of the pin, while the connecting ring 23 and the arc-shaped piece 24 are located between the pin and the inner wall of the female connector 12. The use of insulating materials can effectively prevent the pin from accidentally contacting external metal components (such as the metal shell of the female connector 12, other conductive structures), preventing safety hazards such as short circuits and leakage, and ensuring the stable operation of the vehicle electric drive controller's circuit system.

[0040] The signal transmission of the electric drive controller has extremely high stability requirements. If there is improper contact between conductive parts inside the connector, it may lead to signal interference, noise introduction, and other problems. The insulating sleeve 21, connecting ring 23, and arc-shaped piece 24 can form a physical isolation barrier to prevent unintended conductivity between the pin and surrounding components, reduce the impact of electromagnetic interference (EMI) and radio frequency interference (RFI) on the transmission of electrical signals, and ensure the accurate transmission of control commands or sensing signals.
