[0002] Terminal blocks are common components for achieving electrical connections. With the rapid development of the electrical industry, terminal blocks, as indispensable connectors, have been increasingly used in various electrical devices. Waterproof through-wall terminal blocks are specifically designed to meet specific environmental requirements. They not only ensure stable current transmission but also effectively prevent moisture intrusion. They can also be installed through walls, meeting the needs of various scenarios. Due to their special waterproof design and materials, they can maintain good electrical performance in humid or underwater environments, preventing moisture from interfering with or damaging current transmission. Because the terminal design allows for through-wall installation without additional drilling or opening operations, the installation process is simplified. However, existing waterproof through-wall terminal blocks are inconvenient to unlock quickly during wiring and maintenance, making unlocking relatively difficult. Utility Model Content

[0018] Example 1, referring to Figure 1-4 A waterproof through-wall terminal block with a press-to-unlock mechanism includes a protective cover 1, a nylon nut 3, and a fastening ring 4. The nylon nut 3 is nested on the left outer wall of the protective cover 1, the fastening ring 4 is embedded on the left side of the protective cover 1, a nut 101 is fixed on the top right side of the protective cover 1, a pressure plate 2 is embedded on the top right side of the protective cover 1, a screw 201 is vertically embedded in the middle of the pressure plate 2, a spring 202 is nested below the outside of the screw 201, the rightmost side of the protective cover 1 is closely attached to the main body shell 5, a partition 6 is fixed on the left side of the main body shell 5, a third buckle 7 is fixed on the lower right side of the front and rear ends of the pressure plate 2, a second buckle 8 is fixed on the front and rear ends of the right side of the main body shell 5, and a first buckle 9 is fixed on the lower left side of the front and rear ends of the pressure plate 2.

[0019] The front and rear ends of the right side of the protective cover 1 are both provided with buckle slots, and the second buckles 8 of the front and rear ends of the right side of the main shell 5 are precisely embedded in the buckle slots inside the protective cover 1.

[0020] When the main body shell 5 and its left side partition 6 are embedded in the inside right side of the protective cover 1, the second buckles 8 at the front and rear of the main body shell 5 are engaged in the buckle grooves inside the protective cover 1, so that the main body shell 5 and the protective cover 1 can be quickly assembled together.

[0021] Ribs are provided at both the front and rear ends of the inner side of the pressure plate 2, and one end of the rib is tightly attached to the second buckle 8 of the main body shell 5;

[0022] When unlocking is required, screw 201 is turned up and pressed down to move the pressure plate 2. At this time, the ribs on the inner side of the pressure plate 2 will press the second buckle 8 on the main body shell, pushing the second buckle 8 inward and no longer engaging with the second buckle 8, thereby achieving the unlocking effect.

[0023] The front and rear ends of the lower right side of the protective cover 1 are fixed with a third buckle seat and a first buckle seat. The third buckle 7 and the first buckle 9 in the pressure plate 2 are just fastened to the outside of the third buckle seat and the first buckle seat.

[0024] After the pressure plate 2 is pressed down, the first latch 9 locks into the first latch seat. This way, even if the hand on the pressure plate 2 does not apply downward pressure, the pressure plate 2 will not spring back upward under the action of the spring 202. Only after the protective cover 1 is slid outward horizontally and pulled out will the first latch 9 disengage from the first latch seat and become ineffective. Only then will the pressure plate 2 spring back upward under the action of the spring 202 and reach the corresponding position under the action of the third latch 7, thus completing the unlocking operation.

[0025] Example 2 differs from Example 1 in that, in this example, the front and rear ends of the inner wall of the pressure plate 2 are provided with slide rail grooves, and the front and rear ends of the outer wall of the protective cover 1 are fixed with tracks. The slide rail groove of the pressure plate 2 is nested in the track of the protective cover 1, and the pressure plate 2 moves up and down in the track of the protective cover 1 through the slide rail groove.

[0026] The pressure plate 2 slides on the track of the protective cover 1 through the slide rail groove, so as to achieve the misalignment and offset during the up and down sliding of the pressure plate 2;

[0027] The function of spring 202 is that after the terminal is unlocked, spring 202 generates a rebound force to push pressure plate 2 upward. However, because there is a first buckle 9 on the protective cover, pressure plate 2 will not fall off from the top of the protective cover 1 when it rebounds upward.

[0028] The bottom of the screw 201 above the pressure plate 2 is precisely embedded in the nut 101 of the protective cover 1, and the outer wall of the screw 201 and the inner wall of the nut 101 are connected by threads.

[0029] When the screw 201 on the pressure plate 2 is fully screwed into the nut 101 of the protective cover 1, the bottom surface of the screw 201 presses against the upper surface of the protective cover 1, thus restricting the downward direction of the pressure plate 2. And because the third buckle 7 is engaged with the third buckle seat, the upward direction of the pressure plate 2 is restricted, thereby fixing the pressure plate 2 and keeping the pressure plate 2 in an unlocked state.

[0030] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
