Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wiring terminals, in particular to a wiring terminal with a hook. Background Art
[0002] At present, most of the existing electronic products or equipment are modular in design. Each module realizes different functions. Each module is interconnected with the host. The interconnection is generally completed by connecting wires. There are mostly wiring terminals on both sides of the wires. In order to ensure a good connection between the module and the host, the wiring terminals play a very critical role. Conventional wiring terminals have no hook structure. During the connection process, they only rely on their own plug-in force to ensure the connection effect. Especially when the number of PINs is relatively small, the plug-in force will also be relatively small. When the plug-in force is relatively small, the male and female connections are very easy to fall off after falling off. After falling off, the module and the host cannot work normally, which will bring fatal quality risks to the product. In addition, the existing wiring terminal wiring method is mostly screw-locking type, that is, first unscrew the screw from the block, then put the wire into the block, and then re-tighten the screw to connect the screw with the copper wire of the wire. This method has a slow wiring efficiency and has strict requirements on the strength of the screw lock. If it is locked too tightly, it may cause the screw to slip, and if it is locked too loose, it may cause poor contact. Utility Model Content

[0021] In order to facilitate understanding of the above technical solution of the present invention, the above technical solution of the present invention is described in detail below through specific usage.
[0022] When the device is in use, the peeled copper wire of the wire is passed through the rear rubber core threading hole 402. When the copper wire of the wire contacts the spring clip 3, it continues to be inserted forward. Since the spring clip 3 is pushed by the copper wire of the wire, the spring clip force arm supporting the fillet 302 will move in a circular arc trajectory with the center of the fillet, so that the copper wire completely passes through the spring clip contact block 304 and then the copper wire head hits the terminal copper wire limiting plane 214. At this time, the threading action is completed. In order to prevent the threaded copper wire from curling up, a wire stop block 205 is also designed on the terminal. Since the spring clip 3 has a certain elasticity, it will generate a reaction force while bearing the action force. The copper wire of the wire is always pressed between the spring clip contact block 304 and the terminal anti-slip groove 204 under the reaction force, thereby completing the connection between the wire and the terminal. When the wire needs to be taken out, the button 5 can be pressed by hand or the button slot 502 can be pressed with a tool. Similarly, under the action of the force, the button push block 501 will move forward and touch the spring movable block 303. When the button 5 moves forward to a certain extent, the spring movable block 303 will tilt upward. When the spring movable block 303 tilts up to a certain extent, the spring contact block 304 will create a distance from the copper wire of the wire. When the distance is created, the copper wire will not be subjected to any external force, so it can be pulled out at will.
[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
