Description

Technical Field

[0001] This application relates to the field of automotive connector technology, and in particular to a connector back-locking structure that is easy to disassemble. Background Technology

[0002] Automotive connectors are electrical components that enable signal transmission and power supply between various electronic systems and electrical components within a vehicle. They are widely used in engine control systems, body electronic systems, chassis control systems, and in-vehicle entertainment systems, among other fields.

[0003] In actual assembly and use, automotive connectors need to be connected to various components to ensure the effective transmission of signals and electrical energy. Existing connection methods mostly use the back-locking structure of the connector.

[0004] However, current connector back-clamp structures are typically designed with high assembly force requirements to ensure the stability of the connection. Workers need to apply considerable force to complete the snap-fit ​​installation, which makes the disassembly process more labor-intensive and time-consuming, and inconvenient for workers' installation and disassembly operations, thus presenting obvious shortcomings. Utility Model Content

[0005] To facilitate easy assembly and disassembly between the connector and the component to be connected, this application provides a connector back-locking structure that is easy to disassemble.

[0006] The connector back-locking structure that is easy to disassemble provided in this application adopts the following technical solution: A detachable connector back-locking structure includes a connector and a component to be connected. The connector and the component to be connected are detachably connected by a snap-fit ​​assembly. The snap-fit ​​assembly includes a limiting frame disposed on the component to be connected. The connector is provided with a mounting seat for inserting into the limiting frame. The mounting seat is provided with a spring tongue. The surface of the spring tongue is provided with a first locking block. The component to be connected is provided with a second locking block that engages with the first locking block. When the first locking block abuts against the second locking block, the mounting seat is limited to inside the limiting frame.

[0007] By adopting the above technical solution, during connection, the mounting base is inserted into the limiting frame. The spring tongue is deformed downward by the pressure applied by the second locking block. When the mounting base reaches its travel position, the pressure applied by the second locking block is released, and the spring tongue resets under its own elastic force. At this time, the first locking block abuts against the second locking block and produces a clicking sound, reminding the worker that the installation is in place. During disassembly, the worker pushes the spring tongue downward, and the spring tongue drives the first locking block to move downward synchronously, so that the locking relationship between the first locking block and the second locking block is released. At this time, the mounting base is no longer constrained by the second locking block, and the worker can easily pull the mounting base out of the limiting frame to complete the disassembly of the connector and the part to be connected. The design of the locking component allows the worker to release the locking without applying excessive external force, reducing the manpower and time consumption during disassembly and realizing convenient disassembly and assembly between the connector and the part to be connected.

[0008] Optionally, the limiting frame includes two guide seats arranged opposite each other, the guide seats having an L-shaped cross-section, and guide strips that slide with the guide seats on opposite sides of the mounting seat, and a sealing plate is provided at the end of each guide seat away from the second locking block.

[0009] By adopting the above technical solution, the sliding cooperation of the guide seat and the guide strip guides the insertion of the mounting seat, avoids the mounting seat from shifting or tilting during the insertion process, ensures that the first locking block can be aligned with the locking position of the second locking block, and at the same time, the sealing plate limits the insertion stroke of the mounting seat to prevent damage to the spring or locking block due to excessive insertion.

[0010] Optionally, the end face of the first card block near the sealing plate is provided with a first inclined surface, and the end face of the second card block away from the sealing plate is provided with a second inclined surface that slides with the first inclined surface. The first inclined surface and the second inclined surface have the same inclination direction.

[0011] By adopting the above technical solution, during the connection process, when the mounting base with the first locking block is inserted into the limiting frame, the first inclined surface first contacts the second inclined surface. Since the two inclined surfaces are in the same direction, as the mounting base continues to advance, the first inclined surface will slide along the second inclined surface. At this time, the force of the second locking block on the first locking block will be converted into a component force that causes the spring tongue to deform downward through the inclined surface. In this way, the worker does not need to apply excessive pressure. The spring tongue can deform naturally under the action of the component force generated by the inclined surface, which further improves the convenience of worker operation.

[0012] Optionally, the end face of the spring tongue away from the part to be connected is provided with a reinforcing rib.

[0013] By adopting the above technical solution, the reinforcing rib can disperse the stress generated when the spring is deformed, avoid damage such as cracking and breakage of the spring due to local stress concentration, adapt to the application scenario where the snap-fit ​​component needs to be reassembled multiple times, and extend the service life of the spring.

[0014] Optionally, the mounting base is provided with a toggle assembly, the toggle assembly includes a pin at the end of the spring tongue, a rotating shaft is rotatably connected inside the mounting base, a pull rope is fixedly wound on the rotating shaft, the free end of the pull rope is bolted to the pin, a rotating block is coaxially provided at the end of the rotating shaft, and a rotating groove is provided inside the mounting base to rotatably cooperate with the rotating block.

[0015] By adopting the above technical solution, during disassembly, the worker drives the rotating shaft to rotate. As the shaft rotates, the pull rope winds and tightens around it. The free end of the pull rope exerts a downward pull on the end of the spring latch via a bolt, causing the spring latch to deform downwards and disengage the first and second locking blocks. At this point, the worker can easily pull the mounting base out of the limiting frame, completing the disassembly. The design of the actuating component eliminates the need for the worker to reach into the narrow gaps of the mounting base to operate the spring latch, further reducing the difficulty of disassembly and improving operational convenience.

[0016] Optionally, the rotating block is provided with a limiting component, the limiting component including limiting blocks arranged opposite to each other along the radial direction of the rotating block, the rotating block having a sliding groove that slides with the limiting blocks, the inner sidewall of the rotating groove having a plurality of limiting grooves that insert with the limiting blocks along the circumferential direction, a push spring being sleeved on the outer surface of the limiting block, the elastic force of the push spring pushing the limiting block to insert into the limiting groove, the limiting block being provided with a push block, and the inner sidewall of the sliding groove having a push groove that slides with the push block.

[0017] By adopting the above technical solution, when the rotating shaft needs to be rotated, the worker overcomes the elastic force of the push spring and presses the two levers towards the center of the rotating block. The levers drive the limit block to disengage from the limit groove. At this time, the limit block releases the rotation constraint of the rotating block, and the rotating block can rotate freely to drive the rotating shaft to rotate. When the rotating shaft rotates to the correct position, the worker releases the levers, and the push spring resets under its own elastic force, pushing the limit block to insert into the limit groove. At this time, the rotating block is limited and fixed, ensuring the stability of the spring tongue. The setting of the limit component restricts the rotation state of the rotating shaft, limits the unexpected rotation of the rotating block, and avoids the possibility of the rotating shaft tightening the pull rope on its own due to accidental contact, which could lead to deformation of the spring tongue. This ensures the stability of the connection between the connector and the part to be connected.

[0018] Optionally, the mounting base is provided with a first indicator mark and a second indicator mark for indicating the position of the limiting groove. When the limiting block is inserted into the limiting groove corresponding to the first indicator mark, the pull rope is in a slack state. When the limiting block is inserted into the limiting groove corresponding to the second indicator mark, the pull rope causes the spring to keep the first locking block disengaged from the second locking block.

[0019] By adopting the above technical solution, workers can intuitively judge the status of the pull rope through the first indicator and the second indicator, which shortens the operation judgment time and further improves the overall efficiency of connection and disassembly.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. This application incorporates a snap-fit ​​component, which allows workers to release the snap-fit ​​without applying excessive external force, reducing the manpower and time consumed during disassembly and enabling convenient assembly and disassembly between the connector and the part to be connected. 2. By setting a first inclined surface and a second inclined surface, during the connection process, when the mounting base with the first locking block is inserted into the limiting frame, the first inclined surface first contacts the second inclined surface. Since the two inclined surfaces are in the same direction, as the mounting base continues to advance, the first inclined surface will slide along the second inclined surface. At this time, the force of the second locking block on the first locking block will be converted into a component force that causes the spring tongue to deform downward through the inclined surface, so that the worker does not need to apply excessive pressure. 3. By setting up a toggle component, this application eliminates the need for workers to reach into the narrow gap of the mounting base to operate the spring, thereby further reducing the difficulty of disassembly and improving the ease of operation.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0029] This application discloses a connector back-locking structure that is easy to disassemble.

[0030] Example 1 Reference Figure 1 and Figure 2 A connector back buckle structure that is easy to disassemble includes a connector 01 and a component to be connected 02. The connector 01 and the component to be connected 02 are detachably connected by a snap-fit ​​assembly 1. The snap-fit ​​assembly 1 includes a limiting frame 11 installed on the connecting surface of the component to be connected 02. The limiting frame 11 includes two guide seats 111 arranged opposite to each other. The cross-section of the guide seats 111 is L-shaped. A sealing plate 112 is integrally formed on one side end face of each guide seat 111.

[0031] Reference Figure 1 and Figure 2 The connector 01 is equipped with a mounting base 12 for inserting the limiting frame 11. The mounting base 12 has guide strips 13 integrally formed on both opposite sides that slide in cooperation with the guide seat 111. The sliding cooperation between the guide seat 111 and the guide strips 13 guides the insertion of the mounting base 12 and prevents the mounting base 12 from shifting or tilting during insertion. During the insertion of the mounting base 12 into the limiting frame 11, the guide strips 13 slide inside the guide seat 111, and the L-shaped structure of the guide seat 111 restricts the vertical displacement of the mounting base 12.

[0032] Reference Figure 1 , Figure 2 and Figure 3A spring tongue 14 is installed at the center of the mounting base 12. The spring tongue 14 is made of elastic material and the elastic force is directed towards the part to be connected 02. A first locking block 15 is connected to the upper surface of the spring tongue 14. A second locking block 16 is installed on the part to be connected 02 and engages with the first locking block 15. When the guide strip 13 abuts against the cross section of the sealing plate 112, the flat surface of the first locking block 15 abuts against the flat surface of the second locking block 16. At this time, the mounting base 12 is limited inside the limiting frame 11.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The first locking block 15 has a first inclined surface 151 at the end near the sealing plate 112, and the second locking block 16 has a second inclined surface 161 at the end away from the sealing plate 112 that slides with the first inclined surface 151. The first inclined surface 151 and the second inclined surface 161 have the same inclination direction and are both inclined from top to bottom along the direction near the sealing plate 112.

[0034] When connecting the component to be connected 02 and the connector 01, align the mounting base 12 with the opening direction of the frame to be limited 11, so that the guide bar 13 is aligned with the inner sidewalls of the two guide seats 111 respectively. Then, push the mounting base 12 inward along the length direction of the guide seat 111. As the mounting base 12 is inserted, the first inclined surface 151 of the first locking block 15 gradually contacts the second inclined surface 161 of the second locking block 16. During the process of the first inclined surface 151 sliding along the second inclined surface 161, the second locking block 16 applies downward pressure to the first locking block 15 through the inclined surface engagement, causing the spring tongue 14 to deform in the direction away from the component to be connected 02. When the mounting base 12 is pushed to the end of the guide bar 13 abutting against the end face of the sealing plate 112, the insertion stroke of the mounting base 12 reaches the preset position. At this time, the pressure of the second locking block 16 on the first locking block 15 disappears, and the spring tongue 14 resets under its own elastic force. The flat surface of the first locking block 15 and the flat surface of the second locking block 16 abut tightly, completing the locking engagement. During disassembly, the worker presses the spring tongue 14 away from the part to be connected 02, causing the spring tongue 14 to deform downwards against its own elasticity. The spring tongue 14 drives the first locking block 15 downwards, releasing the locking relationship between the first locking block 15 and the second locking block 16. Then, while keeping the spring tongue 14 pressed, the worker pulls the mounting base 12 out of the limiting frame 11, and finally releases the spring tongue 14 to reset it. The connector 01 and the part to be connected 02 are separated, and the disassembly process is completed. This design allows the worker to release the locking without applying excessive external force, reducing the manpower and time consumption during the disassembly process, and realizing convenient assembly and disassembly between the connector 01 and the part to be connected 02.

[0035] Reference Figure 3A reinforcing rib 17 is installed on the end face of the spring tongue 14 away from the part to be connected 02. The reinforcing rib 17 is distributed along the length of the spring tongue 14. The reinforcing rib 17 can disperse the stress generated when the spring tongue 14 deforms, which is suitable for the use scenario where the snap-fit ​​assembly 1 needs to be reassembled many times, and extends the service life of the spring tongue 14. The implementation principle of the connector back buckle structure that is easy to disassemble in this application embodiment is as follows: When connecting the part to be connected 02 and the connector 01, the mounting base 12 is aligned with the opening direction of the limiting frame 11, so that the guide strip 13 is aligned with the inner sidewalls of the two guide seats 111 respectively. Then, the mounting base 12 is pushed inward along the length direction of the guide seats 111. As the mounting base 12 is inserted, the first inclined surface 151 of the first locking block 15 gradually contacts the second inclined surface 161 of the second locking block 16. The first inclined surface 151 moves along the second inclined surface 161. During the sliding process, the second locking block 16 applies downward pressure to the first locking block 15 through the inclined surface engagement, causing the spring tongue 14 to deform in the direction away from the part to be connected 02. When the mounting base 12 is pushed to the end of the guide strip 13 and abuts against the end face of the sealing plate 112, the insertion stroke of the mounting base 12 reaches the preset position. At this time, the pressure of the second locking block 16 on the first locking block 15 disappears, and the spring tongue 14 resets under its own elastic force. The flat surface of the first locking block 15 and the flat surface of the second locking block 16 abut tightly, completing the locking engagement. During disassembly, the worker presses the spring tongue 14 away from the part to be connected 02, causing the spring tongue 14 to deform downwards against its own elasticity. The spring tongue 14 drives the first locking block 15 downwards, releasing the locking relationship between the first locking block 15 and the second locking block 16. Then, while keeping the spring tongue 14 pressed, the worker pulls the mounting base 12 out of the limiting frame 11, and finally releases the spring tongue 14 to reset it. The connector 01 and the part to be connected 02 are separated, and the disassembly process is completed. This design allows the worker to release the locking without applying excessive external force, reducing the manpower and time consumption during the disassembly process, and realizing convenient assembly and disassembly between the connector 01 and the part to be connected 02.

[0036] Example 2 Reference Figure 4 and Figure 5 The difference between Embodiment 2 and Embodiment 1 is that a toggle assembly 2 is provided inside the mounting base 12. The toggle assembly 2 includes a rotating shaft 21 rotatably connected inside the mounting base 12. The rotating shaft 21 is parallel to the length direction of the spring tongue 14. A pull rope 22 is fixedly wound around the outer surface of the part of the rotating shaft 21 that extends out of the mounting base 12. A bolt 23 is installed on the end face of the spring tongue 14 away from the part to be connected 02. The free end of the pull rope 22 extends upward and is bolted to the bolt 23. A rotating block 24 is coaxially fixedly connected to the end of the rotating shaft 21 away from the pull rope 22. The area of ​​the rotating block 24 is larger than that of the rotating shaft 21. A rotating groove 3 is opened on the outer surface of the mounting base 12 to rotate and cooperate with the rotating block 24.

[0037] Reference Figure 5 and Figure 6 A limiting component 4 is provided on the rotating block 24. The rotating block 24 has two opposing sliding grooves 241 radially. The limiting component 4 includes a limiting block 41 slidably connected inside the sliding groove 241. A lever 42 is fixedly connected to one end of the limiting block 41 near the center of the rotating block 24. The lever 42 is perpendicular to the limiting block 41. A lever groove 242 for the lever 42 to move is provided on the inner wall of the sliding groove 241. Multiple limiting grooves 31 are evenly spaced circumferentially on the inner wall of the rotating groove 3. In this embodiment, the number of limiting grooves 31 is eight. A push spring 43 is sleeved on the outer surface of the positioning block 41. One end of the push spring 43 is connected to the bottom of the sliding groove 241, and the other end is connected to the inner end face of the limiting block 41. In its natural state, the elastic force of the push spring 43 pushes the outer end of the limiting block 41 into the sliding groove 241. The limiting component 4 restricts the unexpected rotation of the rotating block 24, preventing the rotating shaft 21 from tightening the pull rope 22 due to accidental contact, which could cause the spring tongue 14 to deform. This ensures the stability of the connection between the connector 01 and the part to be connected 02.

[0038] Reference Figure 4 , Figure 5 and Figure 6 The outer surface of the mounting base 12 is provided with a first indicator mark 121 and a second indicator mark 122 for indicating the position of the limiting groove 31. In this embodiment, the first limiting mark is circular and the second indicator mark 122 is X-shaped. When the limiting block 41 is inserted into the limiting groove 31 corresponding to the first indicator mark 121, the pull rope 22 is in a slack state, and the spring tongue 14 remains in a natural state. When the limiting block 41 is inserted into the limiting groove 31 corresponding to the second indicator mark 122, the pull rope 22 makes the spring tongue 14 keep the first locking block 15 disengaged from the second locking block 16.

[0039] The implementation principle of Example 2 is as follows: Before installation, the limiting block 41 is inserted into the limiting groove 31 corresponding to the first indicator mark 121. At this time, the pull rope 22 is in a slack state and does not exert force on the spring tongue 14. The worker connects the connector 01 and the part to be connected 02 using the installation method of Example 1. When disassembly is required, the worker first overcomes the elastic force of the push spring 43 and presses the two levers 42 toward the center of the rotating block 24. The levers 42 drive the limiting block 41 to disengage from the limiting groove 31. At this time, the rotation constraint of the limiting block 41 on the rotating block 24 is released, and the rotating block 24 can rotate freely. The worker rotates the rotating block 24 to drive the rotating shaft 21 to rotate several times. When the rotating shaft 21 rotates, the pull rope 22 is wound and tightened on the rotating shaft 21. The free end of the pull rope 22 is connected to the spring tongue 14 through the bolt 23. The end generates a downward pulling force, causing the spring tongue 14 to deform downwards, thereby disengaging the first locking block 15 from the second locking block 16. At this time, the rotational resistance of the rotating block 24 increases, and the limiting block 41 rotates to the limiting groove 31 indicated by the second indicator. The worker releases the toggle block 42, pushes the spring 43 to reset under its own elastic force, and pushes the limiting block 41 into the limiting groove 31 at the second indicator. The rotating block 24 is limited and fixed, and the spring tongue 14 remains in a downward state. The worker pulls the mounting base 12 outwards to make it disengage from the limiting frame 11, completing the disassembly process. The setting of the toggle component 2 eliminates the need for the worker to put their hand into the narrow gap of the mounting base 12 to operate the spring tongue 14, thereby further reducing the difficulty of disassembly and improving the convenience of operation.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
