A stable automotive connector

Abstract

This application relates to the technical field of connectors, and discloses a stable automotive connector, including a socket and a plug. The socket has a placement groove for inserting the plug, and a conductive element is disposed in the placement groove. The plug has a receiving groove for inserting a terminal, and a limiting hole communicating with the receiving groove. The plug also has a limiting strip for inserting into the limiting hole. When the limiting strip is inserted into the limiting hole, the limiting strip is located on the side of the terminal away from the conductive element. This application utilizes the limiting strip's insertion into the limiting hole, where the hole wall can limit the limiting strip, allowing it to be stably positioned on the plug. Furthermore, the limiting strip's location on the side of the terminal away from the conductive element restricts the terminal's movement on the plug, making it less likely for the terminal and conductive element to separate, thus reducing the possibility of separation due to vehicle bumps.

Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular to a stable automotive connector. Background Technology

[0002] Automotive connectors are key electronic components used in automotive electrical systems to enable power, signal, or data transmission between various electronic components. Automotive connectors require high stability, high reliability, and high safety to ensure normal signal transmission during vehicle operation.

[0003] In related technologies, automotive connectors include plugs and sockets. The socket has a receiving groove for inserting the plug, and a conductive element is provided on the bottom wall of the receiving groove. The plug has a placement groove for inserting terminals. When the plug is inserted into the receiving groove, the terminals in the placement groove can communicate with the conductive element in the receiving groove.

[0004] During vehicle operation, the vehicle may experience bumpy travel, which could cause the connector to shake. This could lead to the terminals moving within their slots, potentially causing instability in the connection between the terminals and conductive components, thus affecting the normal use of the connector. Summary of the Invention

[0005] To improve the problem of terminal movement within the placement slot, this application provides a stable automotive connector.

[0006] This application provides a stable automotive connector, employing the following technical solution: A stable automotive connector includes a socket and a plug. The socket has a placement groove for inserting the plug, and a conductive element is disposed in the placement groove. The plug has a receiving groove for inserting a terminal, and a limiting hole communicating with the receiving groove. The plug also has a limiting strip for inserting into the limiting hole. When the limiting strip is inserted into the limiting hole, the limiting strip is located on the side of the terminal away from the conductive element.

[0007] By adopting the above technical solution, the limiting strip is inserted into the limiting hole, and the hole wall of the limiting hole can limit the limiting strip, so that the limiting strip can be stably positioned on the plug. In addition, the limiting strip is located on the side of the terminal away from the conductive part, so that the limiting strip can restrict the movement of the terminal on the plug, making it less likely for the terminal and the conductive part to separate, thereby reducing the possibility of separation of the terminal and the conductive part due to vehicle bumps.

[0008] Optionally, the limiting strip is provided with a limiting block located on the side of the limiting strip, and the plug is provided with a limiting groove for the limiting block to be inserted. The limiting groove is provided with a snap-fit ​​structure, which is used to fix the limiting block in the limiting groove.

[0009] By adopting the above technical solution, the limiting block is fixed in the limiting groove through the snap-fit ​​structure, so that the limiting block can be fixed on the plug and the limiting strip can be stably located in the limiting hole. This allows the limiting strip to fix the terminal, making it difficult for the terminal to detach directly from the plug and reducing the possibility of the terminal and plug separating during the movement of the plug.

[0010] Optionally, the socket has a groove for connecting the placement slot, the groove for inserting the limiting strip; when the plug is installed on the socket, the limiting strip is located in the groove, and the limiting block is located in the limiting slot.

[0011] By adopting the above technical solution, when the staff inserts the plug into the socket, the plug moves the limiting strip, allowing the limiting strip to be located in the groove. This allows the groove wall to restrict the limiting strip, reducing the possibility of the limiting strip coming off directly from the limiting hole. As a result, the socket can restrict the limiting strip, further improving the reliability of the limiting strip within the limiting hole.

[0012] Optionally, the insertion path of the limiting bar and the sliding path of the moving bar intersect, and the moving bar is provided with a moving spring, which drives the moving bar to be located on the insertion path of the limiting bar.

[0013] By adopting the above technical solution, the movable spring drives the movable strip to be located on the insertion path of the limiting strip. When the operator inserts the limiting strip, the operator needs to first slide the movable strip so that the movable strip can exit the insertion path of the limiting strip, so that the limiting strip can be smoothly inserted into the limiting hole. The movable spring abuts against the movable strip, so that the movable strip can squeeze the limiting strip, reducing the possibility of the limiting strip moving in the limiting hole.

[0014] Optionally, the movable strip has a movable inclined surface, and the distance between the movable inclined surface and the movable spring gradually increases along the insertion direction of the limiting strip. The movable inclined surface is located in the insertion path of the limiting strip.

[0015] By adopting the above technical solution, when the limiting strip is inserted into the limiting hole, the limiting strip can drive the moving strip to move through the moving inclined surface, so that the operator does not need to slide the moving strip before inserting the limiting strip, thus reducing the operator's operation steps.

[0016] Optionally, the groove extends through to the side of the socket, and an operating block is slidably connected within the groove. The operating block is located on the side of the limiting strip near the opening in the groove's through-path direction, and the operating block is used to restrict the locking strip from disengaging from the groove in the through-path direction.

[0017] By adopting the above technical solution, if the worker forgets to insert the limiting strip into the limiting hole, the worker can slide the operating block and then insert the limiting strip into the limiting hole through the opening of the groove. Finally, the worker can reset the operating block so that the operating block can prevent the limiting strip from coming out of the opening in the direction of the groove. This eliminates the need for the worker to remove the plug from the socket and reinsert it, further saving the worker's operation steps and making it easier for the worker to quickly install the limiting strip.

[0018] Optionally, a rotating bar is rotatably connected to the limiting bar, and the rotating bar is provided with a receiving spring for abutting the terminal. The receiving bar is provided in the placement groove, and the receiving bar is located in the insertion path of the rotating bar. When the plug is inserted into the socket, the receiving spring can abut the terminal.

[0019] By adopting the above technical solution, since the receiving strip is located on the insertion path of the rotating strip, the receiving strip can drive the rotating strip to rotate, so that the rotating strip can smoothly rotate in the direction of the limiting strip. The receiving spring abuts against the terminal. Due to the process error between the terminal and the conductive part, the terminal and the conductive part cannot be perfectly matched, and the limiting strip cannot directly abut against the end face of the terminal. At this time, the receiving spring abuts against the terminal, so that the terminal can move in the direction of the conductive part, thereby allowing the terminal to stably abut against the conductive part, reducing the possibility of relative displacement of the terminal on the conductive part due to process error.

[0020] Optionally, the socket has a through hole, and the receiving strip has a receiving spring. The receiving spring drives the receiving strip to move in the direction of the rotating strip. When the terminal is in the receiving groove, the receiving strip covers the through hole. When the terminal is not in the receiving groove, the receiving strip does not cover the through hole.

[0021] By adopting the above technical solution, when the terminal is located in the receiving groove, the receiving spring drives the receiving strip to move towards the rotating strip, so that the receiving strip can drive the rotating strip to rotate, allowing the receiving spring on the rotating strip to smoothly abut the terminal. Since the terminal is located in the receiving groove, the terminal exerts a force on the receiving spring, preventing the rotating strip from continuing to rotate, so that the receiving strip can still block the through hole, allowing the operator to know that the terminal is located in the receiving groove. When the terminal is not in the receiving groove, the rotating strip can continue to rotate, that is, the receiving strip does not block the through hole, and the operator can know that the terminal is not in the receiving groove. By checking whether the receiving strip blocks the through hole, the operator can determine whether there is a terminal inside the connector without opening the connector, avoiding the situation where the connector cannot be connected due to the omission of a terminal.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The limiting strip is inserted into the limiting hole. The wall of the limiting hole can limit the limiting strip, allowing it to be stably positioned on the plug. In addition, the limiting strip is located on the side of the terminal away from the conductive part, which restricts the movement of the terminal on the plug and makes it less likely for the terminal and the conductive part to separate, thereby reducing the possibility of separation of the terminal and the conductive part due to vehicle bumps.

[0023] 2. When the terminal is in the receiving groove, the receiving spring moves the receiving strip towards the rotating strip, allowing the receiving strip to rotate and the receiving spring on the rotating strip to smoothly contact the terminal. Because the terminal is in the receiving groove, the terminal exerts a force on the receiving spring, preventing the rotating strip from continuing to rotate. This allows the receiving strip to still block the through hole, indicating that the terminal is in the receiving groove. When the terminal is not in the receiving groove, the rotating strip can continue to rotate, meaning the receiving strip does not block the through hole, indicating that the terminal is not in the receiving groove. By checking whether the receiving strip blocks the through hole, the operator can determine whether there is a terminal inside the connector without opening the connector, avoiding situations where the connector cannot be connected due to a missed terminal.

[0026] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0027] Example 1 This embodiment discloses a stable automotive connector. (Refer to...) Figure 1 and Figure 2 A stable automotive connector includes a socket 1 and a plug 2, wherein the socket 1 has a slot 11 for inserting the plug 2.

[0028] Reference Figure 2 The plug 2 has multiple receiving slots 21 for inserting terminals, and multiple conductive elements 12 are fixedly connected in the slots 11. When the plug 2 is inserted into the socket 1, the conductive elements 12 are inserted into the terminals, thus connecting the circuit.

[0029] Reference Figure 3 A limiting hole 22 is formed on the surface of the plug 2, and the limiting hole 22 connects to multiple receiving grooves 21. A limiting strip 3 is provided on the plug 2, and the limiting strip 3 is used to insert into the limiting hole 22. At this time, the limiting strip 3 is located on the side of the terminal away from the bottom wall of the placement groove 11, that is, the limiting strip 3 restricts the separation of the terminal and the conductive part 12.

[0030] Reference Figure 3 The limiting strip 3 has a limiting block 31, which is located on the side of the limiting block 31 and is C-shaped. A limiting groove 221 for inserting the limiting block 31 is formed on the surface of the plug 2. The limiting groove 221 connects to the limiting hole 22 and is C-shaped. When the limiting block 31 is inserted into the limiting groove 221, it covers one side of the plug 2.

[0031] Reference Figure 3 A snap-fit ​​structure 32 is provided within the limiting groove 221, which is used to fix the limiting block 31 within the limiting groove 221. The snap-fit ​​structure 32 includes a snap-fit ​​block and a snap-fit ​​groove. The snap-fit ​​block is fixedly connected to the limiting block 31, and the snap-fit ​​groove is formed on the plug 2. The snap-fit ​​block can be inserted into the snap-fit ​​groove to fix the limiting block 31 to the plug 2. In other embodiments, the snap-fit ​​block can be disposed within the limiting groove 221, the snap-fit ​​groove can be formed on the plug 2, or the snap-fit ​​structure 32 can be configured as other structures that achieve fixation through a snap-fit ​​method.

[0032] Reference Figure 2 The socket 1 has a groove 13 that connects to the placement slot 11. The groove 13 allows the limiting strip 3 to be inserted in the direction of plug 2 insertion. When plug 2 is inserted into the socket 1, the groove wall of the groove 13 can prevent the limiting strip 3 from disengaging from the socket 1.

[0033] Reference Figure 2 and Figure 3A retaining strip 23 is fixedly connected to the surface of the plug 2. A retaining plate 231 is integrally formed on the retaining strip 23. Both the retaining plate 231 and the retaining strip 23 are elastic and are arranged perpendicular to each other. A stop block 14 is fixedly connected to the wall of the placement slot 11. A stop hole 232 for the stop block 14 to be inserted is opened on the surface of the retaining plate 231. When the plug 2 is inserted into the socket 1, the retaining plate 231 first deforms, allowing the stop block 14 to be located in the stop hole 232, thereby fixing the plug 2 and the socket 1 relatively.

[0034] The implementation principle of Example 1 is as follows: The worker first inserts the terminal into the receiving groove 21, then inserts the limiting strip 3 into the limiting hole 22, and inserts the limiting block 31 into the limiting groove 221 to fix the limiting strip 3 onto the plug 2. Finally, the worker inserts the plug 2 into the socket 1 so that one end of the limiting strip 3 can be located in the groove 13.

[0035] Example 2 Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that the plug 2 has a movable groove 24, which connects to the limiting hole 22. A movable spring 241 is fixedly connected to the bottom wall of the movable groove 24, and a movable strip 242 is fixedly connected to the surface of the movable spring 241 away from the bottom wall of the movable groove 24. The movable spring 241 drives the movable strip 242 to protrude out of the movable groove 24. When the movable strip 242 protrudes out of the movable groove 24, the movable spring 241 is in a compressed state.

[0036] Reference Figure 5 A movable inclined surface 243 is formed on the surface of the movable strip 242. The distance between the movable inclined surface 243 and the movable spring 241 gradually increases along the insertion direction of the limiting strip 3, and the moving path of the movable inclined surface 243 intersects the insertion path of the limiting strip 3. When the limiting strip 3 is located in the limiting hole 22, the limiting strip 3 is located on the moving path of the movable strip 242, and the limiting strip 3 restricts the movement of the movable strip 242.

[0037] Reference Figure 4 and Figure 5 The groove 13 extends through to the outer surface of the socket 1, and the limiting strip 3 can disengage from the placement slot 11 through the opening in the groove 13. An operating slot communicating with the groove 13 is provided on the outer surface of the socket 1, and an operating spring is fixedly connected within the operating slot. An operating block 15 is slidably connected within the groove 13, and the operating spring drives the operating block 15 to block the opening in the groove 13 through the groove. When the plug 2 is inserted into the socket 1, the limiting strip 3 is located within the groove 13 and the placement slot 11, at which point the operating block 15 can prevent the limiting strip 3 from disengaging from the placement slot 11 through the groove 13.

[0038] Reference Figure 6Multiple rotating grooves 33 are provided on the side of the limiting strip 3, and the rotating grooves 33 are arranged in an array along the length direction of the limiting strip 3.

[0039] Reference Figure 7 A rotating bar 331 is rotatably connected inside the rotating groove 33, and the rotating bar 331 can rotate in the vertical direction. A receiving spring 332 is fixedly connected to one end of the rotating bar 331, and the receiving spring 332 can abut against the side of the terminal away from the bottom wall of the placement groove 11.

[0040] Reference Figure 5 and Figure 7 The outer surface of the socket 1 has a through hole 16 that connects to the placement slot 11, and the surface of the retaining plate 231 has a through hole 161. Multiple through holes 161 and through holes 161 are formed. When the plug 2 is inserted into the socket 1, the through hole 161 and the through hole 16 are aligned. A receiving block 25 is fixedly connected to the surface of the retaining plate 231 near the plug 2. A receiving spring 251 is fixedly connected to the surface of the receiving block 25. A receiving strip 252 is fixedly connected to the surface of the receiving spring 251 away from the receiving block 25. The receiving spring 251 drives the receiving strip 252 to move on the surface of the retaining plate 231. The moving path of the receiving strip 252 intersects the rotation path of the rotating strip 331. The receiving spring 251 drives the receiving strip 252 to move, allowing the receiving strip 252 to drive the rotating strip 331 to rotate, thus enabling the receiving spring 332 to abut against the terminal.

[0041] Reference Figure 5 and Figure 7 When plug 2 is inserted into socket 1, through hole 16 aligns with through hole 161. The accommodating spring 251 drives the accommodating strip 252 to move, causing the accommodating strip 252 to drive the rotating strip 331 to rotate, so that the accommodating spring 332 abuts against the terminal. At this time, the accommodating strip 252 can block through hole 16 and through hole 161. By observing whether through hole 161 and through hole 16 are blocked, the staff can know whether the internal terminal of plug 2 is missing. When the connection between the wire and the terminal is blocked due to the need for dust and water protection, it is possible to quickly distinguish whether the terminal is missing.

[0042] Reference Figure 5 and Figure 7 When the terminal is not in the receiving slot 21, the plug 2 is inserted into the socket 1, the through hole 16 is aligned with the through hole 161, the receiving spring 251 drives the receiving strip 252 to move, and the receiving strip 252 drives the rotating strip 331 to rotate. Since the receiving spring 332 does not abut against the terminal, the rotating strip 331 can continue to rotate, allowing the receiving strip 252 to continue to push the rotating strip 331 to rotate. That is, the receiving strip 252 will not block the through hole 16 and the through hole 161. The staff can know whether the terminal is missing by observing the through hole 161 and the through hole 16.

[0043] The implementation principle of Example 2 is as follows: When the plug 2 is inserted into the socket 1, the through hole 16 is aligned with the through hole 161. The accommodating spring 251 drives the accommodating strip 252 to move, so that the accommodating strip 252 drives the rotating strip 331 to rotate, so that the accommodating spring 332 abuts against the terminal. At this time, the accommodating strip 252 can block the through hole 16 and the through hole 161.
