In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 9, the detachable connector of the present invention will now be described. The detachable connector comprises a first cylinder body 11 (cylinder body: tubular object with through hole; optionally, in one embodiment, the cylinder body is a cylinder; specifically, in one embodiment, the axis of the cylinder is a straight line), a second cylinder body 12 with one end inserted into the first cylinder body 11, a third cylinder body 13 sleeved and fixed on the other end of the second cylinder body 12, a fourth cylinder body 14 sleeved outside the third cylinder body 13 and capable of sliding relative to the third cylinder body 13, a first conductive terminal (not shown) arranged in the first cylinder body 11, and a second conductive terminal (not shown) arranged in the second cylinder body 12 and mutually inserted with the first conductive terminal; the third cylinder 13 is provided with a first hook 21, and the outer surface of the first cylinder 11 is provided with a concave part 111 for hooking the first hook 21; the fourth cylinder 14 is provided with a second hook 22; when the fourth cylinder 14 slides with respect to the third cylinder 13, the second hook 22 hooks the first hook 21 and pulls the first hook 21 out of the recess 111.

Thus, when one end of the second cylinder 12 is inserted into the first cylinder 11, the first conductive terminal in the first cylinder 11 and the second conductive terminal in the second cylinder 12 are connected to each other and can be conducted; the first barrel 11 is sleeved on the second barrel 12, so that the stability of the relative position between the second barrel 12 and the first barrel 11 is enhanced, and the two barrels are not easy to separate from each other; the second barrel 12 and the first barrel 11 are communicated with each other for a circuit to pass through; the first hook body 21 is arranged on the third cylinder 13, and the third cylinder 13 is sleeved and fixed on the second cylinder 12, so that the first hook body 21 can be more stably arranged on the second cylinder 12 through the third cylinder 13, and the first hook body 21 and the second cylinder 12 are not easy to separate; when the first hook body 21 is hooked in the recessed part 111, the first barrel body 11 is hooked on the second barrel body 12 through the first hook body 21, so that the connection firmness of the second barrel body 12 and the first barrel body 11 is enhanced, and the looseness is not easy to occur; the fourth cylinder 14 is sleeved outside the third cylinder 13, so that the third cylinder 13 can be effectively protected, and the influence of the external environment on the third cylinder 13 is reduced; if the first hook 21 needs to be unhooked from the recess 111, the fourth barrel 14 is slid to make the second hook 22 on the fourth barrel 14 hook the first hook 21 and pull the first hook 21 out of the recess 111, so as to release the locking between the first barrel 11 and the second barrel 12, and the user can separate the first barrel 11 and the second barrel 12 conveniently.

Alternatively, in one embodiment, the fourth cylinder 14 slides even if the second hook 22 hooks the first hook 21 and pulls the first hook 21 out of the recess 111; in another embodiment, the fourth cylinder 14 slides a certain distance to hook the second hook 22 to the first hook 21 and pull the first hook 21 out of the recess 111.

Optionally, in one embodiment, the first conductive terminal and the second conductive terminal are copper terminals, respectively.

Optionally, in one embodiment, the third cylinder 13 is detachably fixed on the second cylinder 12. Thus, the third cylinder 13 is convenient to mount and dismount.

Optionally, in an embodiment, a first annular groove is disposed on an outer surface of the second cylinder 12, a second annular groove is disposed on an inner wall of the third cylinder 13, the first annular groove and the second annular groove surround to form a receiving hole, and a limiting member is filled in the receiving hole. Thus, when the third cylinder 13 is fixed on the second cylinder 12, only the first annular groove and the second annular groove need to be aligned with the groove receiving hole and the limiting member needs to be 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 second cylinder 12 and the third cylinder 13 are prevented from being separated from each other.

Further, referring to fig. 1 to 9, as an embodiment of the detachable connector provided by the present invention, the recess 111 is an annular groove disposed on the outer surface of the first cylinder 11. Thus, the first hook 21 can be very conveniently clamped into the clamping groove by sliding along the first barrel 11 at different positions of the first barrel 11.

Further, referring to fig. 1 to 9, as an embodiment of the detachable connector provided by the present invention, the third cylinder 13 and the first hook 21 are respectively located in a space surrounded by the fourth cylinder 14. Therefore, the fourth cylinder 14 can protect the third cylinder 13 and the first hook 21 from being affected at the same time, and the influence of the external environment on the third cylinder 13 or the first hook 21 and the unhooking of the first hook 21 are reduced.

Further, referring to fig. 1 to 9, as an embodiment of the detachable connector provided by the present invention, an anti-slip pattern 141 is disposed on an outer surface of the fourth cylinder 14. Thus, when the user needs to slide the first barrel 11, the anti-slip pattern 141 can avoid slipping.

Further, referring to fig. 1 to 9, as an embodiment of the detachable connector provided by the present invention, the second hook 22 is located at the edge of the fourth cylinder 14. Therefore, the second hook 22 is easy to process, and the second hook 22 can prevent the first hook 21 in the fourth cylinder 14 from sliding out of the fourth cylinder 14.

Further, referring to fig. 1 to 9, as an embodiment of the detachable connector provided by the present invention, a predetermined gap is left between the third cylinder 13 and the fourth cylinder 14. Thus, the gap between the third cylinder 13 and the fourth cylinder 14 can provide a moving space for the first hook 21 to bend and deform, and the situation that the first hook 21 is blocked is reduced.

Further, referring to fig. 1 to 9, as an embodiment of the detachable connector provided by the present invention, the first cylinder 11, the second cylinder 12, the third cylinder 13 and the fourth cylinder 14 are coaxially disposed respectively. Therefore, the first barrel 11 and the second barrel 12 are easier to insert and are not easy to collide with each other; the fourth cylinder 14 is more convenient relative to the third cylinder 13 and is not easy to collide with each other.

Further, referring to fig. 1 to 9, as an embodiment of the detachable connector provided by the present invention, a direction in which the second hook 22 hooks the first hook 21 is a direction extending along the third barrel 13 and away from the first barrel 11. Thus, after the first hook 21 hooks the first barrel 11, the user pulls the fourth barrel 14 along the third barrel 13 in a direction away from the first barrel 11 to hook the first hook 21, so as to unhook the first hook 21, which is very convenient to operate.

Further, referring to fig. 1 to 9, as an embodiment of the detachable connector provided by the present invention, the first hook body 21 includes an elastic plate 211 and a barb 212 having a first guiding surface 213 and extending into the recess 111, one end of the elastic plate 211 is connected to the barb 212, and the other end of the elastic plate 211 is connected to the third barrel 13; the second hook 22 is provided on the inner wall of the fourth cylinder 14, the second hook 22 being located on the moving path of the first guide surface 213; the first guide surface 213 is located at a distance from the axis of the first cylinder 11 in a direction along the first guide surface 213 to slide toward the second hook 22 (when the second hook 22 slides toward the first guide surface 213, the same is true of the first guide surface 213 sliding toward the second hook 22). As such, since the first guide surface 213 is located on the moving path of the second hook 22, and in the direction sliding along the first guide surface 213 toward the second hook 22, the distance of the first guide surface 213 from the axis of the first cylinder 11 becomes longer; such that when the first guide face 213 moves toward the second hook body 22 (equivalent to the second hook body 22 sliding toward the first guide face 213) and continues to move while abutting against the second hook body 22, the barb 212 moves in the direction away from the axis of the first barrel 11 under the guide of the first guide face 213 (wherein, when the barb 212 moves in the direction away from the axis of the first barrel 11, the elastic plate 211 bends to accommodate the movement) to release the first barrel 11 hooked by the barb 212 (wherein the release may be complete unhooking of the barb 212 from the recess 111, or may be reduction in the tightness of the barb 212 hooked on the recess 111 to facilitate the user's disengagement of the barb 212).

Optionally, in one embodiment, the elastic plate 211 and the barb 212 are each made of copper. Thus, the copper has good toughness.

Optionally, in one embodiment, the first guide surface 213 is a flat surface. Thus, the plane surface is easy to process, and the second hook 22 is not easily hindered from moving on the plane surface.

Alternatively, in one embodiment, the elastic plate 211 extends in the axial direction of the third cylinder 13. Thus, when the third cylinder 13 slides relative to the fourth cylinder 14, the elastic plate 211 is not easily collided with the inner wall of the fourth cylinder 14.

Further, referring to fig. 1 to 9, as an embodiment of the detachable connector provided by the present invention, a rib 131 is disposed on an outer surface of the third cylinder 13, and a groove 143, which extends along a circumferential direction of an inner wall of the fourth cylinder 14 and into which the rib 131 is inserted, is disposed on an inner wall of the fourth cylinder 14. Thus, the rib 131 on the third cylinder 13 is snapped into the groove 143 on the inner wall of the fourth cylinder 14 to restrain the third cylinder 13 in the fourth cylinder 14 to prevent the third cylinder 13 from sliding out of the fourth cylinder 14; in addition, since the groove 143 extends along the circumferential direction of the inner wall of the fourth cylinder 14, the rib 131 can slide into the groove 143 from multiple positions of the inner wall of the fourth cylinder 14 along the axial direction of the fourth cylinder 14; when the third cylinder 13 slides along the fourth cylinder 14, the rib 131 moves in the groove 143.

Further, referring to fig. 1 to 9, as an embodiment of the detachable connector provided by the present invention, the inner wall of the fourth barrel 14 has a second guiding surface 142 for guiding the rib 131 to slide into the groove 143. In this way, the rib 131 is more easily slid into the groove 143 by the second guide surface 142.

Alternatively, in one embodiment, the number of the elastic plate 211, the barb 212, and the second hook 22 is plural; the plurality of elastic plates 211, the plurality of barbs 212, and the plurality of second hooks 22 correspond one to one. In this manner, the plurality of barbs 212 catch the external object more securely.

Alternatively, in one embodiment, the plurality of second hooks 22 are integrally formed. In this manner, the plurality of barbs 212 may engage the plurality of second hooks 22 that are joined together, and the plurality of second hooks 22 are joined together more securely.

Optionally, in an embodiment, the elastic plates 211 are respectively and sequentially arranged on the annular bottom surface of one end of the third cylinder 13; the spacing between adjacent elastic plates 211 is the same in the direction extending along the annular bottom surface of the third cylinder 13. In this way, the external force applied to each barb 212 can be evenly distributed to the annular bottom surface of the third cylinder 13 by the elastic plate 211.

Optionally, in one embodiment, the plurality of elastic plates 211 enclose to form a receiving cavity with an opening for an external object to extend into; each barb 212 extends into a respective 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 212 can prevent the external object from being disengaged from the opening after the object is hooked.

Optionally, in one embodiment, the barb 212 is integral with the spring plate 211 to provide more rigidity and copper has better toughness to accommodate deformation.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
