Description

Technical Field

[0001] The utility model relates to the technical field related to notebook computers, in particular to an anti-drop mechanism for a notebook charging connector. Background Art

[0002] During the use of the laptop, a charging power source is required for charging. The charging power source includes a connection line connected to the computer, and one end of the connection line is provided with a charging connector adapted to the charging port of the computer. The computer can be charged by inserting the charging connector into the charging port of the computer.

[0003] The utility patent with the existing patent announcement number CN215803542U discloses a laptop charging connector anti-slip structure, which makes the No. 1 charging connection block and the No. 2 charging connection block tightly connected by the rubber suction cups on both sides compressing and adsorbing each other, and plays an anti-slip effect. When the metal plug rod is inserted into the plug slot, the limit ring is just clamped in the limit ring groove, which further plays an anti-slip effect;

[0004] However, during use, the above mechanism not only needs to keep the suction cup clean to maintain the adsorption effect, which is relatively inconvenient, but also the charging cable is often accidentally pulled during computer charging, causing the charging connector to fall off from the computer charging port due to force. When the limit ring is subjected to a large force, it is still unable to prevent the charging connector from separating from the computer charging port, which can easily affect the normal charging of the computer.

[0033] Specifically, the elastic extrusion assembly 42 includes: an extrusion rod 421, a pull rod 422 and a first compression spring 423. An extrusion groove is provided inside the charging connection block 2 and the plug rod 41, and the extrusion rod 421 is slidably inserted and connected with the inner cavity of the extrusion groove; a plurality of pull rods 422 are fixedly connected with a plurality of extrusion rods 421 respectively, and a plurality of pull grooves are provided on the outer wall of the charging connection block 2, and the pull rod 422 is slidably inserted and connected with the inner cavity of the pull groove; the first compression spring 423 is located inside the extrusion groove. One end of the first compression spring 423 is fixedly connected with the extrusion rod 421, and the other end of the first compression spring 423 is fixedly connected with the inner wall of the extrusion groove. The first compression spring 423 is always in a compressed state, so as to provide a stable elastic force to the extrusion rod 421, so that the extrusion rod 421 can stably provide an extrusion force to the clamping block 431, so that the clamping block 431 always remains in an extended state, and the pull rod 422 can pull the extrusion rod 421, so that the extrusion rod 421 no longer compresses the clamping block 431.

[0034] Specifically, the anti-drop assembly 43 includes: a clamping block 431, a slider 432, a sliding block 433, a connecting rope 434 and a second compression spring 435. A clamping groove is provided on one side of the inner wall of the extrusion groove, a clamping hole is provided on one side of the inner wall of the slot, the clamping block 431 is slidably inserted and connected with the inner cavity of the clamping groove, the clamping block 431 is slidably inserted and connected with the inner cavity of the clamping hole, and an inclined surface is provided on the other side of the clamping block 431.
