Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connection mechanism that utilizes a hook to quickly connect and disconnect connectors. Background Technology

[0002] Connectors are commonly used electronic components in electronic engineering. Their function is to connect circuits and transmit electrical energy or signals. One end of the connector connects to two different parts of the circuit. When the connectors are mated, the two circuit parts are electrically connected. After mating, the connector should have the following functions: ensuring electrical contact; facilitating easy mating and quick insertion / removal; and withstanding a certain amount of vibration and impact after mating to ensure stable and reliable electrical contact. Common connector connection methods include through-hole connections, bayonet connections, and threaded connections.

[0003] However, the connector is slow to connect and disconnect during use, which is time-consuming. Also, when the connector is being inserted, it is prone to loosening when subjected to external impact, resulting in instability. Therefore, further improvements are needed. Utility Model Content

[0004] This utility model proposes a connection mechanism that utilizes a hook telescopic mechanism for quick connection and separation of connectors, solving the problems in related technologies where it is inconvenient to quickly and easily connect and disconnect connectors.

[0005] The technical solution of this utility model is as follows:

[0006] A connection mechanism for quickly connecting and separating connectors using a hook telescopic connection includes a plug body, a socket body is provided on one side of the plug body, a second plug is fixedly connected to one side of the plug body, a connecting rod is fixedly connected to the other side of the socket body, and a contact core is fixedly connected to the upper end of the socket body.

[0007] Preferably, a first plug is fixedly connected to one side of the socket body, a flat notch is provided on the outer surface of the socket body, and the side of the socket body away from the first plug is engaged with the connecting rod in the plug body.

[0008] Preferably, the outer shell of the contact core is provided with a positioning window.

[0009] Preferably, the positioning window is provided with a hook inside.

[0010] Preferably, a connecting sleeve is slidably connected to the outer surface of the socket body.

[0011] Preferably, a constraint spring is sleeved on one side of the hook.

[0012] Preferably, one end of the constraint spring is fixedly connected to the positioning window, and the constraint spring is in a stretched state.

[0013] Preferably, the connecting sleeve is provided with an axial spring and a retaining ring inside, the retaining ring is located on the second plug side in the plug body, and the axial spring is in a compressed state.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] This invention involves inserting the socket body into the connecting rod of the plug body, with the socket body inserted into the contact core. The movement of the socket body contacts the hook, which, under the push of the socket body, continues to stretch the constraint spring. As the socket body continues to move, and the flat notch of the socket body aligns with the hook, the hook, under the contraction of the constraint spring, instantly falls into the flat notch with a crisp sound, indicating that the connector is quickly connected. After connection, when the cables on both sides are pulled, the hook is locked in the positioning window of the contact core, fixing the plug body to prevent relative movement. This ensures stable and reliable connection, solving the problem of inconvenient and quick connector connection.

[0016] This invention, by moving the connecting sleeve backward, compresses the axial spring. Since the middle part of the hook and the edge of the positioning window act as fulcrums, forming a lever principle, the connecting sleeve pushes one end of the hook downward, and due to the lever principle, it lifts the other end of the hook upward, causing the hook to pull the constraint spring away from the positioning window. The connecting sleeve then causes the plug body and socket body to separate quickly. After separation, the hook falls into the positioning window in the contact core due to the contraction of the constraint spring and resets, thus solving the problem of inconvenient quick and convenient separation of the connector.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-5 As shown, this embodiment proposes a connection mechanism for quick connection and separation of connectors using a hook telescopic connection, including a plug body 1, a socket body 2 provided on one side of the plug body 1, a second plug 11 fixedly connected to one side of the plug body 1, a connecting rod 12 fixedly connected to the other side of the socket body 2, and a contact core 13 fixedly connected to the upper end of the socket body 2.

[0026] Furthermore, a first plug 21 is fixedly connected to one side of the socket body 2, and a flat notch 22 is provided on the outer surface of the socket body 2. The side of the socket body 2 away from the first plug 21 is correspondingly engaged with the connecting rod 12 in the plug body 1. The connecting rod 12 is used to connect the plug body 1 and the socket body 2.

[0027] Furthermore, the outer shell of the contact core 13 is provided with a positioning window 15, and a hook 17 is provided inside the positioning window 15. A connecting sleeve 16 is slidably connected to the outer surface of the socket body 2. A constraint spring 18 is sleeved on one side of the hook 17. One end of the constraint spring 18 is fixedly connected to the positioning window 15. An axial spring 19 and a retaining ring 14 are provided inside the connecting sleeve 16. The retaining ring 14 is located on the side of the second plug 11 in the plug body 1. The constraint spring 18 is in a stretched state, and the axial spring 19 is in a compressed state. The hook 17 is used to engage and limit the connection between the plug body 1 and the socket body 2.

[0028] The working principle and usage instructions of this utility model are as follows: When the connector is plugged in, the socket body 2 is inserted into the connecting rod 12 in the plug body 1, and the socket body 2 is inserted into the contact core 13. The movement of the socket body 2 touches the hook 17. Under the push of the socket body 2, the hook 17 continues to stretch the constraint spring 18. When the socket body 2 continues to plug and move, and moves to the point where the flat notch 22 of the socket body 2 is aligned with the hook 17, the hook 17 falls into the flat notch 22 instantly under the contraction of the constraint spring 18 and makes a crisp sound, indicating that the connector is quickly plugged in. After the connector is plugged in, when the cables on both sides are pulled, the hook 17 is stuck in the positioning window 15 in the contact core 13, fixing the plug body 1 and the plug body 1 so that they cannot move relative to each other, thereby ensuring stable and reliable plugging.

[0029] When the connector needs to be separated, the connecting sleeve 16 is moved backward, compressing the axial spring 19. Since the middle part of the hook 17 and the edge of the positioning window 15 form a lever principle as a fulcrum, the connecting sleeve 16 pushes one end of the hook 17 downward, and due to the lever principle, it lifts the other end of the hook 17 upward, causing the hook 17 to pull the constraint spring 18 away from the positioning window 15. The connecting sleeve 16 drives the plug body 1 and the socket body 2 to separate quickly. After separation, the hook 17 falls into the positioning window 15 in the contact core 13 and resets due to the contraction of the constraint spring 18.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
