Description
Technical Field
[0001] The utility model belongs to the technical field of automobile connectors, in particular to a rotary lock type automobile connector. Background Art
[0002] The automotive power connector builds a bridge of communication between blocked or isolated circuits within the circuit, thereby allowing current to flow and enabling the circuit to achieve its intended function.
[0003] The utility model patent with publication number CN216015827U discloses a connector end cap mounting structure and an automotive connector, comprising a connector housing and an end cap disposed at an opening of the housing. The end cap is reversibly disposed on the housing, and an elastic member and a snap-fit structure are disposed between the housing and the end cap. The elastic member is used to drive the end cap to flip over to seal the opening; with the end cap in place, the snap-fit structure forms a snap-fit connection between the end cap and the housing. This product utilizes the snap-fit structure disposed between the housing and the end cap to snap-fit the sealed end cap to the housing, thereby maintaining the end cap's waterproof and dustproof state and improving the connector's waterproof and dustproof performance.
[0004] In actual use, the inventors found that although the end cover can be fastened by the torsion spring when the connector is not in use, the part where one end of the torsion spring contacts may be affected by the external environment and weathered and broken by the external environment and the elastic force of the torsion spring, and the end cover may be in a propped-up state due to the contact of foreign objects. This will cause the connection opening to be unable to be effectively sealed when the connector is not in use. Utility Model Content

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0025] Example:
[0026] See Figure 1 、 Figure 2 、 Figure 3 , a rotary lock type automotive connector includes a connector body 1 and an end cover 2 hinged at the connector opening, a screw-on part 3 is rotatably connected to the connector body 1 / end cover 2, and a locking part 4 is provided on the other of the end cover 2 / connector body 1 to cooperate with the screw-on part 3, and the screw-on part 3 can be closed and opened to connect and separate the screw-on part 3 and the locking part 4, wherein a sealing part 6 such as a rubber ring is provided on the end cover 2. When the screw-on part 3 and the locking part 4 are connected, the sealing part 6 is in a compressed state to ensure dustproof and waterproof effects.
[0027] Specifically, it is assumed that when the connector body 1 is connected to the end cover 2, the end cover 2 is located above the connector body 1. At this time, at least the side wall of the end cover 2 has a circumferential surface extending to the bottom surface, or the side wall of the connector body 1 has a circumferential surface extending to the top surface. The screw-on part 3 is annular and is sleeved on the circumferential surface of the end cover 2 or the connector and can rotate about the center axis of the circumferential surface. There is a locking groove / stop 11 on the side wall of the screw-on part 3. Through the forward and reverse rotation of the screw-on part 3, the locking part 4 can be engaged with or disengaged from the locking groove / stop 11. The locking groove / stop 11 in this embodiment adopts an L-shaped stop. At the same time, the locking part 4 is a short column fixed on the circumferential surface of the end cover 2 or the connector, wherein the side wall of the end cover 2 has a circumferential surface extending to the bottom surface, and the side wall of the connector body 1 has a circumferential surface extending to the top surface, and the screw-on part 3 is arranged on the end cover 2.
[0028] The screw-on member 3 is provided with a limiting guide rail arranged along the circumferential surface of the screw-on member 3 , and the circumferential surface of the screw-on member 3 is provided with a guide portion 10 that cooperates with the limiting guide rail and moves along the direction of the limiting guide rail.
[0029] Among them, the screw-on member 3 and the connector body 1 or the end cover 2 where it is located are provided with a locking anti-slip structure. When the screw-on member 3 is connected to the locking member 4, the anti-slip structure is used to prevent the screw-on member 3 from being disconnected from the locking member 4. The anti-slip structure can be achieved by using a magnet to be attracted to an iron sheet or the like. In this embodiment, the limit guide rail includes a limit short rail 8 and a limit long rail 9 set up in the upper and lower parts, and the limit short rail 8 and the limit long rail 9 are respectively placed on the upper and lower sides of the guide part 10, and the guide part is provided with a A stopper 13 is provided, and an anti-slipping piece is provided on the screw-on piece 3. When the anti-slipping piece passes over the stopper 13, the screw-on piece generates elastic deformation in the radial direction. The limiting short rail in this embodiment is the anti-slipping piece. When the end cover 2 and the connector body 1 are locked by the screw-on piece 3, the locking piece enters the L-shaped stopper, and is blocked by the vertical section of the L-shaped stopper to prevent it from escaping in one direction. At the same time, it is blocked by the anti-slipping piece by the stopper 13, which can prevent the locking piece from escaping from the L-shaped stopper in the unlocking direction.
[0030] The guide portion 10 is provided with a slot 12 having a length not less than that of the limiting short rail 8 to facilitate entry of the limiting short rail 8 . The slot 10 is provided to facilitate assembly of the screw-on component 3 onto the end cover 2 .
[0031] The connector body 1 is provided with a torsion spring 5 , which always applies a force to the end cover 2 to make it snap onto the connector body 1 . Specifically, one end of the torsion spring 5 is connected to the connector body 1 , and the other end is connected to the end cover 2 .
[0032] Among them, the end cover 2 and the connector body 1 are both provided with a protective edge 7. When the end cover 2 is buckled on the connector body 1, the two protective edges 7 are respectively matched with the top and bottom surfaces of the screw-on part 3, and the area enclosed by the edge of the screw-on part 3 falls within the area enclosed by the edge of the protective edge 7. In addition, in this embodiment, the protective edge portion on the end cover protrudes outward to form a warped edge 14, which can facilitate the opening of the end cover.
[0033] The screw-on component 3 is formed in an assembled manner or integrally formed of an elastically deformable material. The assembled manner may be that the screw-on component is divided into two sections and connected by bolts.
[0034] When the screw-on member 3 rotates in the forward direction, the screw-on member 3 and the locking member 4 are connected to each other, and when the screw-on member 3 rotates in the reverse direction, the screw-on member 3 and the locking member 4 are separated.
[0035] Working process and principle:
[0036] When this product is not in use, the end cover 2 will be snapped onto the connector body 1 under the action of the torsion spring 5. At this time, the screw-on part 3 is in the open state. It is rotated according to the set locking direction, and the limiting short rail 8 will pass over the block 13. At this time, the locking part 4 will move to the top of the horizontal side of the L-shaped block, thus completing the locking between the end cover 2 and the connector body 1; when it needs to be used, it is rotated in the opposite direction to make the limiting short rail 8 pass over the block 13 in the opposite direction, and then the locking part is disengaged from the L-shaped block to open the end cover 2.
[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
