Description

Technical Field

[0001] The utility model relates to an electrical connector, in particular to an energy storage connector. Background Art

[0002] A patent document with the application publication number of CN 117134157 A discloses a high-voltage energy storage quick-insert connector, which includes a socket and a plug. An annular slot is provided inside the plug, and an elastic hook in a cantilever structure is provided on the side wall of the annular slot of the plug. The hook body at the free end of the elastic hook can hook the step of the socket, playing a role of primary locking.

[0003] An operating handle is fitted on the elastic hook. The operating handle is provided with a sliding sleeve structure and is sleeved on the elastic hook through the sliding sleeve structure. A first bump is provided at the front end of the operating handle along its sliding direction, and a limiting slot is provided on the circumferential outer side wall of the plug. When the operating handle is pushed forward, the operating handle moves forward relative to the elastic hook, and the first bump is fitted in the limiting slot, and both the operating handle and the elastic hook are in a locked state. When unlocking, the operating handle is pushed backward, and the operating handle moves backward relative to the elastic hook, and the first bump exits the limiting slot. At this time, the tail of the operating handle can be pressed to make the front end of the operating handle tilt up. The operating handle drives the elastic hook to tilt up through the sliding sleeve structure, and the elastic hook releases the step of the socket, and the plug can be separated from the socket.

[0004] For the high-voltage energy storage quick-insert connector in the above patent document, after the plug and the socket are inserted and locked, the connection is more firm and stable, and it avoids the elastic hook and the operating handle being affected by external forces and causing the elastic hook to disengage from the step of the socket when the plug and the socket are locked. However, after the plug is inserted into the socket and locked, it can rotate 360°, and the angle cannot be fixed, which cannot meet the requirements of anti-rotation and installation angle. Summary of the Utility Model

[0005] The technical problem solved by the utility model: For the high-voltage energy storage quick-insert connector in the prior art, after the plug is inserted into the socket and locked, it can rotate 360°, and the angle cannot be fixed, which cannot meet the requirements of anti-rotation and installation angle.

[0006] To solve the above technical problems, the utility model provides the following technical solution: An energy storage connector with a fixed anti-rotation lock structure includes a plug and a socket. The plug includes a plug body and a secondary lock fastener. The plug body is integrally formed with a primary lock fastener. A hook portion is provided at the front end of the primary lock fastener. A secondary lock fastener insertion slot is opened on the plug body. The secondary lock fastener is inserted into the secondary lock fastener insertion slot from back to front and cooperates with the primary lock fastener. Anti-rotation teeth are provided on the socket, and a fixed anti-rotation step capable of cooperating with the anti-rotation teeth is formed on the primary lock fastener. The fixed anti-rotation step is located inside the hook portion.

[0007] The plug is inserted into the socket. The fixed anti-rotation step on the primary locking part is caught in any tooth valley of the anti-rotation teeth. The hook part of the primary locking part passes over the anti-rotation teeth and enters the neck of the socket, hooking the inner end face of the anti-rotation teeth. In this way, the primary locking part can prevent the relative rotation between the plug and the socket and also prevent the separation of the plug and the socket. The secondary locking part locks the locking state of the primary locking part.

[0008] The front end of the secondary locking part along its sliding direction is provided with a locking convex part. A limiting slot is provided on the circumferential outer side wall of the plug body, and the locking convex part can be pushed forward into the limiting slot. When the primary locking part is in the locking state, the secondary locking part is pushed forward, and the locking convex part is inserted into the limiting slot, and the secondary locking part is in the locking state, and the secondary locking part locks the locking state of the primary locking part. When unlocking, first, the secondary locking part retreats, and the locking convex part exits the limiting slot. Then, the tail of the secondary locking part is pressed, the secondary locking part tilts, driving the primary locking part to tilt, the front end of the primary locking part tilts up, and the hook part disengages from the neck of the socket, unlocking the socket and the plug. At this time, the plug and the socket can be separated.

[0009] The locking convex part is provided with a limiting convex point, and the inner wall of the limiting slot is provided with a barb structure, and the limiting convex point can abut against the barb structure. When the primary locking part is in the locking state, the secondary locking part is pushed forward, the locking convex part is inserted into the limiting slot, and after the limiting convex point passes over the barb structure, it closely cooperates with the barb structure to prevent the locking convex part from disengaging from the limiting slot.

[0010] The primary locking part is provided with a stroke limiting convex part, and the secondary locking part is provided with a stroke limiting slot that cooperates with the stroke limiting convex part. The secondary locking part is pushed forward, and the stroke limiting convex part abuts against the tail end of the stroke limiting slot. The secondary locking part retreats, and the stroke limiting convex part abuts against the front end of the stroke limiting slot.

[0011] The secondary locking part is provided with a pushing and pulling part and a pressing part, and the pressing part is located at the tail of the secondary locking part. The operator acts on the pushing and pulling part to drive the secondary locking part to move forward or backward. The operator presses the pressing part to make the front end of the secondary locking part tilt up.

[0012] For the fixed anti-rotation locking structure energy storage connector of the present utility model, the fixed anti-rotation structure (including the hook part and the fixed anti-rotation step) and the primary locking part are made into one body and cooperate with the anti-rotation teeth, which can not only fix and prevent rotation of the socket, but also play the role of buckling and preventing retraction with the plug, achieving the effect of one locking part with two functions.

[0026] Combined with Figure 1 , Figure 2 , Figure 6 , a fixed anti-rotation lock structure energy storage connector includes a plug and a socket 10. The plug includes a plug body 20 and a secondary locking part 30. The plug body is integrally formed with a primary locking part 21. The front end of the primary locking part is provided with a hook part 22. The plug body is provided with a secondary locking part insertion slot 26. The secondary locking part is inserted into the secondary locking part insertion slot from the back to the front and cooperates with the primary locking part. The socket 10 is provided with anti-rotation teeth 11. A fixed anti-rotation step 23 that can cooperate with the anti-rotation teeth is formed on the primary locking part. The fixed anti-rotation step is located inside the hook part.

[0027] Referring to Figure 6 , the front end of the secondary locking part 30 along its sliding direction is provided with a locking convex part 31. A limiting slot 27 is provided on the circumferential outer wall of the plug body 20. The locking convex part can be pushed forward into the limiting slot.

[0028] The locking convex part 31 is provided with a limiting convex point 32, and the inner wall of the limiting slot 27 is provided with a barb structure 28, and the limiting convex point can abut against the barb structure.

[0029] The primary locking part 21 is provided with a stroke limiting convex part 24, and the secondary locking part 30 is provided with a stroke limiting groove 33 that cooperates with the stroke limiting convex part.

[0030] Reference Figure 7 Moreover, the secondary locking part 30 is provided with a pushing part 34 and a pressing part 35, and the pressing part is located at the tail of the secondary locking part.

[0031] The secondary locking part 30 is inserted into the secondary locking part insertion slot 26 from the rear to the front, and the sliding sleeve structure of the secondary locking part 30 is sleeved on the primary locking part 21 to realize the cooperation between the secondary locking part 30 and the primary locking part 21. The plug is inserted into the socket 10, the fixed anti-rotation step 23 on the primary locking part 21 is caught in any tooth valley of the anti-rotation teeth 11, and the hook part 22 of the primary locking part 21 passes over the anti-rotation teeth 11 and enters the neck 12 of the socket 10, hooking the inner end surface of the anti-rotation teeth 11. In this way, the primary locking part 21 can not only prevent the relative rotation between the plug and the socket 10, but also prevent the separation of the plug and the socket, as Figures 4 to 6 shown.

[0032] When the primary locking part 21 is in the locked state, the operator acts on the pushing part 34 to push the secondary locking part 30 forward. The locking convex part 31 is inserted into the limiting slot 27, and the limiting convex point 32 is tightly fitted with the barb structure after passing over the barb structure 28. The secondary locking part 30 is in the locked state, and the secondary locking part locks the locked state of the primary locking part 21.

[0033] When unlocking, reference Figure 7 、 Figure 8 , the secondary locking part 30 retreats, and the locking convex part withdraws from the limiting slot 27. After that, the pressing part 35 of the secondary locking part is pressed, the secondary locking part warps, driving the primary locking part 21 to warp, the front end of the primary locking part warps, and the hook part 22 disengages from the neck 12 of the socket to unlock the socket 10 and the plug. At this time, the plug and the socket can be separated.

[0034] The amplitude of the forward and backward displacement of the secondary locking part 30 is limited by the stroke limiting convex part 24 and the stroke limiting groove 33. When the secondary locking part 30 is pushed forward, the stroke limiting convex part 24 abuts against the tail end of the stroke limiting groove 33. When the secondary locking part 30 retreats, the stroke limiting convex part 24 abuts against the front end of the stroke limiting groove 33.
