4. The components are as follows: the invention mainly comprises five main parts, namely a cover plate, a baffle plate, a traditional plugboard, a base and a self-locking structure.
a. The cover plate is formed by insulating plastic at one time, the shape is shown in the figure, and two or three jacks are reserved on the cover plate. The area below the inner side pressing plate close to each jack is provided with a bulge (middle cover plate), and the middle of the bulge (middle cover plate) is provided with a small hole (threaded hole) connected with the upper lock hook. Two rings which are arranged in parallel with the jacks and protrude are respectively reserved below an outer side pressing plate (a side cover plate) of each jack, and threads are arranged inside the rings.
b. The baffle plate is composed of insulating plastic and anti-skid rubber, and has a shape shown in the figure. The anti-slip rubber is stuck on one surface of the insulating plastic. The baffle is fixed on the cover plate by penetrating through a connecting shaft.
c. The structure of the plug board main body is similar to that of a plug board seen in daily life, and an opening (through hole) penetrating through a traditional plug board is reserved in the middle of each plug hole, and the diameter upper part of the opening is smaller. And the outer shell on the outside of each receptacle is slightly inclined towards the receptacle. The middle portion of each receptacle housing is recessed a bit. A conductive copper sheet corresponding to the plug pins is arranged below each jack, namely inside the traditional plugboard.
d. The base is connected with the traditional plugboards through screws, and corresponding lower lock hooks are fixed on the base below the openings of each traditional plugboard.
e. The self-locking structure comprises an upper lock hook, a lower lock hook and a spring. As shown. The upper lock hook is fixed on the pressing plate through threads, and a spring is sleeved on a part between the cover plate of the upper lock hook and the plugboard main body. The lower lock hook is connected to the base through a bolt and can move around the bolt, and a compression bar part of the lower lock hook extends out of the shell.
5. Structural relation: the baffle and the torsion spring (spring) are connected to the cover plate through threads at two ends of the connecting shaft and a ring on the cover plate, the baffle can rotate around the connecting shaft, and one side of the baffle with the anti-slip rubber faces to the direction of the jack. The top of the upper latch hook is screwed with the middle small hole on the cover plate by a thread, and the upper latch hook firstly penetrates through the middle hole penetrating through the traditional plugboard and then is connected with the middle small hole on the baffle plate. The shape of the upper lock hook is shown in the figure, no fixed connection point is arranged between the cover plate and the traditional plugboard, the cover plate contacts with the plugboard by a spring sleeved between the upper cover plate of the upper lock hook and the plugboard and a baffle plate connected to the cover plate, and the interaction between the middle protruding part (middle cover plate) of the upper lock hook and the shrinkage part of the middle opening of the plugboard can keep the cover plate at a fixed position when no plug is inserted into the plugboard, so that the cover plate is not separated from the traditional plugboard.
6. The use mode and principle are as follows: when the one-key pop-up patch board is to be used, the plug is directly inserted into the corresponding jack on the cover plate, and pressure is applied downwards, so that the spring sleeved on the upper lock hook is deformed. In the process that the cover plate is continuously pressed downwards and the spring is continuously deformed, the baffle plate slides towards the top pin of the plug under the action of the force, and the upper lock hook on the cover plate always moves downwards along with the middle cover plate and is close to the lower lock hook. When the plug top pin is inserted into a traditional patch board and is communicated with the conductive copper sheet, the anti-slip rubber surface of the baffle extrudes the plug top pin, and meanwhile, the upper lock hook and the lower lock hook are self-locked, so that the cover plate is close to the position above the plug board main body. The cover plate forces the baffle plate to always press the plug pins, so that the plug can be stably fixed on the patch board. When the plug is to be pulled out, only a pressing rod part of the lower lock hook is pressed by one hand to separate the lower lock hook from the upper lock hook. When the upper latch hook and the lower latch hook are separated, the deformation force of the pressing spring disappears, so that the cover plate moves upwards under the action of the elastic force of the spring to drive the plug on the cover plate to move upwards. Under the action of the force, the baffle releases the plug top pin and moves in the opposite direction of the plug top pin. Until the protruding part of the upper latch hook is blocked by the small diameter part of the upper part of the through hole of the traditional plugboard, the pressing plate and the baffle stop moving. The plug is not pressed by the baffle plate and always moves upwards by the upward force of the pressing plate and the pressing plate, so that the plug is ejected out due to inertia when the pressing plate stops moving.
