DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0032] As Figures 1-4 shown in the utility model provides a kind of locking structure of connector, including plug 1, with the plug 1 plug joint cooperation of use socket 2 and rotationally connected on the assistance handle 3 of socket 2, first connecting part 31 is equipped on the assistance handle 3, second connecting part 11 is equipped on the plug 1 with the first connecting part 31 corresponding, the first connecting part 31 is engaged with the second connecting part 11 and is connected;The assistance handle 3 can be moved between locking position and unlocking position;

[0033] When using, first the assistance handle 3 on the socket 2 is rotated to unlocking position, then the plug 1 is butt joint with the socket 2 and makes the first connecting part 31 with the second connecting part 11 begin to engage;

[0034] When needing to lock the plug 1 and the socket 2, the assistance handle 3 in the engaged state is moved from unlocking position to locking position (locking direction, as Figure 3 left figure arc line arrow direction) to the first connecting part 31, because the first connecting part 31 is engaged with the second connecting part 11, so the first connecting part 31 will push the second connecting part 11 and drive the plug 1 to move synchronously to the first direction (i.e. the plug 1 moves to the socket 2 direction, as Figure 3 left figure horizontal arrow direction) to the first connecting part 31, because the first connecting part 31 is engaged with the second connecting part 11, so the first connecting part 31 will push the second connecting part 11 and drive the plug 1 to move synchronously to the first direction (i.e. the plug 1 moves to the socket 2 direction, as

[0035] When needing to unlock the plug 1 and the socket 2, the assistance handle 3 is moved from locking position to unlocking position (unlocking direction, as Figure 3The right-hand figure shows the direction of the curved arrow, causing the first connecting part 31 to push the second connecting part 11 and simultaneously move the plug 1 in the second direction (i.e., the direction opposite to the first direction, such as...). Figure 3 Move the plug 1 (in the direction of the horizontal arrow in the right figure) to unlock and disconnect the plug 1 and the socket 2;

[0036] In practical use, the plug 1 and the socket 2 are usually connected to high-current wires, which makes them heavy and difficult to plug in. However, with the help handle 3, after the plug 1 and the socket 2 are properly connected, simply rotating the help handle 3 will drive the plug 1 to be inserted into the socket 2. The pivot of the help handle 3 is located on the first connecting part 31, while the pushing end of the help handle 3 is away from the pivot, thus making the help handle 3 a lever that saves effort. This further reduces the difficulty of plugging in the plug 1 and the socket 2, thereby improving the connection convenience and practicality of the connector.

[0037] Specifically, such as Figure 3 As shown, the peripheral wall of the first connecting part 31 is an arc-shaped structure, and a first tooth 311 is provided on its peripheral wall; the peripheral wall of the second connecting part 11 is provided with a second tooth 111 corresponding to the first tooth 311, and the first tooth 311 and the second tooth 111 mesh with each other; it should be noted that, in order to achieve the same meshing state, the first connecting part 31 may be provided with one first tooth 311, while the second connecting part 11 may be provided with two second teeth 111. When meshing, the first tooth 311 is positioned on both second teeth. Between 111; correspondingly, the number and arrangement position of the first meshing tooth 311 and the second meshing tooth 111 can be interchanged to achieve the same meshing effect; in order to make the meshing force of the first connecting part 31 and the second connecting part 11 more uniform, the length of the first meshing tooth 311 and the second meshing tooth 111 can be reduced to provide multiple meshing tooth structures; therefore, the different numbers and arrangement structures of the first meshing tooth 311 and the second meshing tooth 111 under the same meshing and driving action should be within the protection scope of this utility model;

[0038] Furthermore, such as Figure 4 As shown, to prevent the power handle 3 from rotating too much when unlocking, a limiting protrusion 312 is provided on the peripheral wall of the first connecting part 31, and a limiting step 21 corresponding to the limiting protrusion 312 is provided on the peripheral wall of the socket 2.

[0039] When the power-assisted handle 3 is in the unlocking position, the limiting protrusion 312 abuts against the limiting step 21 to limit the power-assisted handle 3 from continuing to rotate in the unlocking direction, and when the power-assisted handle 3 rotates in the locking direction and is disengaged from the locking position, the limiting protrusion 312 is also disengaged from the limiting step 21;

[0040] The limiting protrusion 312 and the limiting step 21 are simple in structure, facilitating production and processing, and have good rotation limiting effect, and on the basis of limiting abutment between the limiting protrusion 312 and the limiting step 21, a slope structure can be further arranged on the limiting protrusion 312 and / or the limiting step 21, so as to further limit the rotation angle of the power-assisted handle 3;

[0041] Further, as shown in the actual manufacturing, Figure 5 The power-assisted handle 3 is a U-shaped structure, both free ends of the power-assisted handle 3 are provided with the first connecting part 31, the two first connecting parts 31 are symmetrically arranged and rotationally connected to the circumferential wall of the socket 2, and the second connecting part 11 on the plug 1 is provided with two second connecting parts 11 corresponding to the two first connecting parts 31 respectively, so that when the plug 1 is moved by rotating the power-assisted handle 3, the plug 1 is stressed more uniformly and moves more stably.

[0042] In order to further improve the connection stability of the plug 1 and the socket 2, the first locking structure 4 and the second locking structure 5 are further arranged between the socket 2 and the power-assisted handle 3, and the first locking structure 4 and the second locking structure 5 are used to fix the power-assisted handle 3 in the locking position; that is, after the plug 1 and the socket 2 are plugged in place and the power-assisted handle 3 is in the locking position, two locking operations are still required to further fix the power-assisted handle 3 to keep it in the locking position, so as to improve the locking effect of the connector;

[0043] Specifically, as shown in the actual manufacturing, Figures 6-7 The first locking structure 4 includes a locking piece 41 slidingly connected to the upper end surface of the power-assisted handle 3, and a locking groove 42 arranged on the circumferential wall of the socket 2, and when the power-assisted handle 3 is in the locking position, the locking piece 41 is provided with a locking part 411 extending in the second direction and corresponding to the locking groove 42, and when the locking part 411 is clamped in the locking groove 42 by sliding the locking piece 41 in the second direction, the power-assisted handle 3 is limited to rotate in the unlocking direction, so as to realize the rotation locking of the power-assisted handle 3 in the locking position;

[0044] Further, as shown in the actual manufacturing, Figure 8As shown, in order to prevent the locking piece 41 from being loose or automatically detached after being inserted into the locking groove 42, the bottom surface of the locking piece 41 is further fixed with a first locking block 412, and the top surface of the assist handle 3 is further provided with a first locking groove 43 corresponding to the first locking block 412. When the locking piece 41 locks the rotation of the assist handle 3, that is, when the locking portion 411 on the locking piece 41 is located in the locking groove 42, the first locking block 412 is just clamped in the first locking groove 43. When in use, after the locking portion 411 is inserted into the locking groove 42 by pushing the locking piece 41 in the second direction, the first locking block 412 is just clamped in the first locking groove 43. Consumers will have a clamping feeling feedback when using, thereby improving the use feeling of the connector of the utility model.

[0045] It should be noted that, in order to improve the unlocking convenience of the locking piece 41, the end of the first locking block 412 away from the locking groove 42 can be provided with an inclined surface, so as to improve the sliding convenience of the first locking block 412 away from the locking groove 42.

[0046] Preferably, a track and sliding block structure (not shown) can be further arranged between the locking piece 41 and the assist handle 3, so as to further limit the sliding track of the locking piece 41, thereby ensuring that the locking piece 41 can only slide in the first direction and the second direction, and further improving the sliding stability of the locking piece 41.

[0047] Specifically, as shown in the drawings, Figure 9 As shown, the second locking structure 5 includes a second locking block 51 arranged on the peripheral wall of the socket 2, and a second locking groove 52 arranged on the assist handle 3 and corresponding to the second locking block 51. When the assist handle 3 is in the locked position, the second locking block 51 is clamped in the second locking groove 52, thereby achieving the rotation locking of the assist handle 3. When in use, after the assist handle 3 is rotated to the locked position, the second locking groove 52 is just clamped with the second locking block 51, thereby achieving the rapid locking of the assist handle 3, and further improving the convenience and stability of the locking of the first locking structure 4, thereby avoiding the situation that the assist handle 3 cannot be locked by the first locking structure 4 due to the elastic force generated by the deformation of the assist handle 3 or the socket 2 after reaching the locked position.

[0048] Further, as shown in the drawings, Figure 10As shown, in order to improve the convenience of locking and unlocking the second lock groove 52 and the second locking block 51, the second locking block 51 is provided with a first inclined surface 511 for locking the second lock groove 52 and a second inclined surface 512 for unlocking the second lock groove 52. The first inclined surface 511 and the second inclined surface 512 are symmetrically arranged on the peripheral wall of the second locking block 51.

[0049] Preferably, when the second locking structure 5 locks or unlocks the power assist handle 3, the portion of the power assist handle 3 near the second locking groove 52 will be lifted by the second locking block 51.

[0050] Therefore, the power handle 3 is provided with a through hole 32 corresponding to the position of the second locking block 51. An elastic piece 321 is provided in the through hole 32, and the second locking groove 52 is provided on the elastic piece 321. The elastic piece 321 can be a square structure, and one end wall of it is fixedly connected to the inner wall of the through hole 32, while the other sides form a gap 33 with the inner wall of the through hole 32. This allows the elastic piece 321 to undergo slight deformation during locking or unlocking to adapt to the locking and unlocking operation of the power handle 3 by the second locking structure 5. The elastic piece 321 is provided with a first end 521 and a second end 522. The first end 521 is located at the edge of the elastic piece 321, and the second end 522 is located at the end wall of the second locking groove 52.

[0051] When locked, the first end 521 slides against the first inclined surface 511. Due to the inclined surface design of the first inclined surface 511, the first end 521 can easily slide over the first inclined surface 511, making it more convenient and less strenuous for the second locking structure 5 to lock the power handle 3.

[0052] When unlocking, the second end 522 slides against the second inclined surface 512. Due to the inclined surface design of the second inclined surface 512 and the opposite inclination angle of the second inclined surface 512 to the first inclined surface 511, the second end 522 can easily slide over the second inclined surface 512, making it easier and less strenuous for the second locking structure 5 to unlock the power handle 3.

[0053] Specifically, such as Figure 11 As shown, the socket 2 has an inwardly recessed slot 22 on the end face facing the plug 1, and the plug 1 has a plug block 12 corresponding to the slot 22 on the end face facing the socket 2. After the plug 1 and the socket 2 are plugged in, the plug block 12 is inserted into the slot 22. The slot 22 and the plug block 12 provide a guiding function for the plug 1 and the socket 2, thereby improving the stability of the plug 1 and the socket 2.

[0054] Further, at least one pin 221 can be arranged in the slot 22, and the plug 12 is provided with a connecting hole 121 corresponding to the pin 221; after the plug 1 and the socket 2 are connected, the pin 221 is connected in the connecting hole 121.

[0055] The working principle of the utility model is described in detail as follows:

[0056] In use, first, the power-assisted handle 3 is rotated to the unlocking position, then the plug 1 and the socket 2 are connected to make the first connecting part 31 and the second connecting part 11 engage and connect, then the second connecting part 11 can be driven by rotating the power-assisted handle 3 to drive the plug 1 to be connected with the socket 2 in the first direction, or the plug 1 is directly moved to the socket 2 in the first direction by external force to drive the power-assisted handle 3 to rotate to the locking position through the first connecting part 31;

[0057] After the power-assisted handle 3 is rotated to the locking position, the second locking slot 52 is just connected with the second locking block 51 to complete the clamping to lock the power-assisted handle 3 in the locking position, thereby completing the first-step locking operation;

[0058] Finally, the locking part 41 is pushed in the second direction to make the locking part 411 inserted into the locking slot 42 to complete the second-step locking operation.

[0059] When it is needed to be unlocked, the above steps are reversed.

[0060] The utility model discloses the first locking structure and the second locking structure are arranged between the socket and the power-assisted handle, the power-assisted handle is rotated to the locking position, and the first-step automatic locking can be realized through the second locking structure, then the second-step locking of the power-assisted handle is realized in the sliding locking mode of the locking part in the first locking structure.
