Further, referring to fig. 1 to fig. 20, as an embodiment of the connector provided by the present invention, a first sealing ring 53 is disposed in the first elastic cylinder 511, and an outer wall of the first sealing ring 53 abuts against an inner wall of the first elastic cylinder 511; a second sealing ring 54 is arranged in the second elastic cylinder 521, and the outer wall of the second sealing ring 54 abuts against the inner wall of the second elastic cylinder 521. Thus, when the first conducting wire passes through the first sealing ring 53, the first sealing ring 53 can prevent water from permeating along the first conducting wire; similarly, the second sealing ring 54 prevents moisture from penetrating along the second wire when the second wire passes through the second sealing ring 54.

Further, referring to fig. 1 to 20, as an embodiment of the connector provided by the present invention, a first notch 5111 extending along the axial direction of the first elastic cylinder 511 is formed on a side wall of the first elastic cylinder 511 near one end of the first stopping wall 512; a second notch extending along the axial direction of the second elastic cylinder 521 is formed on the side wall of the second elastic cylinder 521 near one end of the second stopping wall 522. Thus, when the first stopping wall 512 presses the first elastic cylinder 511 towards the axial direction of the second cylinder 12, the first notch 5111 can release the pressure applied to the first elastic cylinder 511, so as to facilitate the deformation of the first elastic cylinder 511; similarly, when the second stopper wall 522 extrudes the second elastic cylinder 521 toward the axial direction of the second cylinder 12, the second notch can release the pressure applied to the second elastic cylinder 521, so that the second elastic cylinder 521 deforms.

Further, referring to fig. 1 to 20, as a specific embodiment of the connector provided by the present invention, the fastening mechanism 4 includes a seventh cylinder 41 sleeved and fixed at the other end of the third cylinder 13, an eighth cylinder 42 sleeved at the outer side of the seventh cylinder 41 and capable of sliding relative to the seventh cylinder 41, a first hook 43 disposed on the seventh cylinder 41, and a recess 45 disposed on the outer surface of the fourth cylinder 21 and used for hooking the first hook 43; the eighth cylinder 42 is provided with a second hook 44; when the eighth cylinder 42 slides with respect to the seventh cylinder 41, the second hook 44 hooks the first hook 43 and pulls the first hook 43 out of the recess 45. Thus, the first hook 43 is disposed on the seventh cylinder 41, and the seventh cylinder 41 is sleeved and fixed on the third cylinder 13, so that the first hook 43 can be more stably disposed on the third cylinder 13 through the seventh cylinder 41, i.e. the first hook 43 and the third cylinder 13 are not easily separated; when the first hook 43 is hooked in the recess 45, the fourth cylinder 21 is fixed on the third cylinder 13 through the first hook 43, so that the firmness of connection between the third cylinder 13 and the fourth cylinder 21 is enhanced, and the looseness is not easy to occur; the eighth cylinder 42 is sleeved outside the seventh cylinder 41, so that the seventh cylinder 41 can be effectively protected, and the influence of the external environment on the seventh cylinder 41 is reduced; if the first hook 43 needs to be unhooked from the recess 45, the eighth barrel 42 is slid to make the second hook 44 on the eighth barrel 42 hook the first hook 43 and pull the first hook 43 out of the recess 45, so as to release the locking between the fourth barrel 21 and the third barrel 13, and the user can separate the fourth barrel 21 and the third barrel 13 conveniently.

Thus, when the seventh cylinder 41 is fixed to the third cylinder 13, only the first annular groove and the second annular groove need to be aligned to form the receiving hole, and the limiting member is filled in the receiving hole. Optionally, in an embodiment, the limiting member is a snap ring. Therefore, after the clamping ring is filled in the accommodating hole, the clamping ring is not easy to separate from the accommodating hole under the action of the elasticity of the clamping ring, and the third cylinder 13 and the seventh cylinder 41 are prevented from being separated from each other.

Optionally, in one embodiment, the recess 45 is an annular groove formed around the outer surface of the fourth cylinder 21. Thus, the first hook 43 can be very conveniently snapped into the snap groove by sliding along the fourth cylinder 21 at different positions along the fourth cylinder 21.

Optionally, in an embodiment, the seventh cylinder 41 and the first hook 43 are respectively located in a space surrounded by the eighth cylinder 42. Thus, the eighth cylinder 42 can simultaneously protect the seventh cylinder 41 and the first hook 43 from being affected, and reduce the influence of the external environment on the seventh cylinder 41 or the first hook 43 and cause unhooking of the first hook 43.

Optionally, in an embodiment, the outer surface of the eighth cylinder 42 is provided with anti-slip lines. Thus, when the user needs to slide the fourth cylinder 21, the anti-slip lines can avoid slipping.

Alternatively, in one embodiment, the second hook 44 is located at the edge of the eighth cylinder 42. Thus, the second hook 44 is easy to process, and the second hook 44 can prevent the first hook 43 in the eighth tube 42 from sliding out of the eighth tube 42.

Alternatively, in one embodiment, a predetermined gap is left between the seventh cylinder 41 and the eighth cylinder 42. Thus, the gap between the seventh cylindrical body 41 and the eighth cylindrical body 42 can provide a moving space for the first hook 43 to bend and deform, and the first hook 43 is prevented from being locked.

Further, referring to fig. 1 to 20, as an embodiment of the connector provided by the present invention, the first hook 43 includes an elastic plate 431 and a barb 432 having a guiding surface 4321 and extending into the recess 45, one end of the elastic plate 431 is connected to the barb 432, and the other end of the elastic plate 431 is connected to the seventh barrel 41; the second hook 44 is provided on the inner wall of the eighth cylinder 42, the second hook 44 being located on the moving path of the guide surface 4321; the guide surface 4321 may be spaced further from the axis of the fourth cylinder 21 in the direction of the second hook 44 along the guide surface 4321 (when the second hook 44 slides on the guide surface 4321, the distance may be equivalent to the distance in which the guide surface 4321 slides on the second hook 44). In this manner, since the guide surface 4321 is located on the moving path of the second hook 44, and the guide surface 4321 is located at a distance from the axis of the fourth cylinder 21 in a direction sliding toward the second hook 44 along the guide surface 4321; such that, when the guide face 4321 continues to move after moving toward the second hook body 44 (which is equivalent to the second hook body 44 sliding toward the guide face 4321) and abutting on the second hook body 44, the barb 432 moves in the direction away from the axis of the fourth cylinder 21 under the guide of the guide face 4321 (wherein, when the barb 432 moves in the direction away from the axis of the fourth cylinder 21, the elastic plate 431 bends to accommodate the movement) to release the hooked fourth cylinder 21 (wherein, the release may be complete unhooking of the barb 432 from the recess 45, or reduction in the tightness of the barb 432 hooked on the recess 45 to facilitate the user's separation of the barb 432).

Optionally, in one embodiment, the guide surface 4321 is planar. Thus, the plane surface is easy to process, and the second hook 44 is not easily hindered from moving on the plane surface.

Alternatively, in one embodiment, the elastic plate 431 extends in the axial direction of the seventh cylinder 41. Thus, when the seventh cylinder 41 slides relative to the eighth cylinder 42, the elastic plate 431 does not easily collide with the inner wall of the eighth cylinder 42.

Alternatively, in one embodiment, the number of the elastic plate 431, the barb 432, and the second hook 44 is plural respectively; the plurality of elastic plates 431, the plurality of barbs 432, and the plurality of second hook bodies 44 correspond one to one. As such, the plurality of barbs 432 catch the external object more securely.

Alternatively, in one embodiment, the plurality of second hooks 44 are integrally formed. As such, the plurality of barbs 432 may cooperate with the plurality of second hooks 44 that are joined together, and the plurality of second hooks 44 are joined together more securely.

Alternatively, in one embodiment, the elastic plates 431 are respectively and sequentially arranged on the annular bottom surface at one end of the seventh cylinder 41; the intervals between the adjacent elastic plates 431 are the same in the extending direction along the annular bottom surface of the seventh cylinder 41. In this way, the external force applied to each barb 432 can be evenly distributed to the annular bottom surface of the seventh cylindrical body 41 by the elastic plate 431.

Optionally, in one embodiment, the plurality of elastic plates 431 surround to form a receiving cavity with an opening for an external object to extend into; each barb 432 extends into the receiving cavity. Thus, if an external object needs to be hooked, the external object only needs to extend into the accommodating cavity from the opening, and the barb 432 can prevent the external object from being disengaged from the opening after hooking the object.

Optionally, in one embodiment, the barb 432 is integral with the spring plate 431 to provide more rigidity and copper has better toughness to accommodate deformation.

Optionally, in one embodiment, the resilient plate 431 and the barb 432 are both copper. Thus, the copper has good toughness.
