[0022] Please see Figures 1-6 This utility model provides a technical solution: a quick wiring device for a marine magnetic starter, comprising: a magnetic starter body 1 and a connecting wire 5; a switch button element 2 is provided on the cover plate of the magnetic starter body 1, and L-shaped grooves 3 are symmetrically opened on the housing of the switch button element 2, the wiring contacts 4 of the switch button element 2 extend into the L-shaped grooves 3, and a wiring contact plate 6 is provided at the end of the connecting wire 5; the wiring contact plate 6 is snapped into the L-shaped grooves 3, and the wiring contact plate 6 is set on the switch button element 2 through an auxiliary component.

[0023] The insert ring 7 in the auxiliary component is fixedly sleeved on the connecting line 5, and the housing of the switch button element 2 is symmetrically provided with grooves 8, and the insert ring 7 is snapped into the grooves 8.

[0024] The wiring contact plate 6 is snapped into the L-shaped groove 3 to facilitate contact between the wiring contact plate 6 and the wiring contact 4. The insert ring 7 on the connecting line 5 is snapped into the groove 8 to limit the horizontal movement of the connecting line 5.

[0025] The pressure tube 10 is movably disposed in the L-shaped groove 3. The pressure tube 10 is located above the wiring contact 4. The wiring contact plate 6 is provided with a concave edge that fits and conforms to the wiring contact 4. The pressure tube 10 is snapped into the wiring contact plate 6. Slider 11 is symmetrically connected to the periphery of the pressure tube 10. The slider 11 is movably snapped into the sliding groove 9. A spring 12 is connected to the bottom wall of the slider 11.

[0026] A concave edge is provided on the wiring contact plate 6. The inner arc surface of the concave edge of the wiring contact plate 6 is adapted and fits against the wiring contact 4. The bottom end of the pressure tube 10 is snapped into the wiring contact plate 6. The outer arc surface of the concave edge of the wiring contact plate 6 is provided on the inner wall of the pressure tube 10, so that the pressure tube 10 can press down against the wiring contact plate 6 to ensure stable contact between the wiring contact plate 6 and the wiring contact 4. The slider 11 is movably snapped into the slide groove 9. The compressed spring 12 is located in the slide groove 9. When the spring 12 returns to its original position, it pushes the slider 11 upward.

[0027] The end of the pressure tube 10 is connected to an arc panel 13. One end of the L-shaped push plate 14 is rotatably connected in the L-shaped groove 3. The other end of the L-shaped push plate 14 is provided with a wire-locking groove 15, which is engaged with the connecting wire 5. The end of the L-shaped push plate 14 is engaged with the insert ring 7.

[0028] When the end of the L-shaped push plate 14 contacts the housing of the switch button element 2, the wire locking groove 15 engages with the connecting wire 5, and at the same time, the side wall of the end of the L-shaped push plate 14 engages with the side wall of the embedded ring 7, thereby preventing the wiring contact plate 6 from disengaging from the wiring contact 4 when the connecting wire 5 is pulled, and further ensuring the wiring stability of the switch button element 2.

[0029] The inner sidewall of the L-shaped push plate 14 is engaged with the arc surface of the arc panel 13. A through hole 16 is provided on the sidewall of the L-shaped push plate 14. The damping shaft 17 is rotatably mounted on the bottom wall of the L-shaped groove 3. A retaining plate 18 is connected to the top peripheral wall of the damping shaft 17. The damping shaft 17 and the retaining plate 18 are movably mounted in the through hole 16.

[0030] When the L-shaped push plate 14 rotates, the inner sidewall of the L-shaped push plate 14 contacts the arc surface of the arc panel 13, which is used to push the pressure tube 10 to move downward. During the rotation of the L-shaped push plate 14, the damping shaft 17 and the clamping plate 18 pass through the through hole 16.

[0031] The card plate 18 is engaged with the L-shaped push plate 14. The side wall of the card plate 18 is provided with a buckle groove 19. The side wall of the L-shaped push plate 14 is provided with a protrusion 20. The side wall of the protrusion 20 is provided with an elastic buckle 21. The elastic buckle 21 is engaged with the buckle groove 19.

[0032] The bottom wall of the card plate 18 is engaged with the end of the L-shaped push plate 14 to fix the position of the L-shaped push plate 14. The side wall of the card plate 18 is engaged with the side wall of the protrusion 20. The elastic buckle 21 is engaged with the buckle groove 19 to fix the position of the card plate 18.

[0033] Working principle: When wiring the switch button element 2 of the marine magnetic starter, the wiring contact plate 6 at the end of the connecting wire 5 is snapped into the L-shaped groove 3, so that the inner arc surface of the concave edge of the wiring contact plate 6 fits and conforms to the wiring contact 4, and the insert ring 7 is snapped into the groove 8. Then, the L-shaped push plate 14 is rotated. During the rotation of the L-shaped push plate 14, the inner wall of the L-shaped push plate 14 abuts against the arc surface of the arc panel 13. As the L-shaped push plate 14 rotates, it pushes the arc panel 13 downward. The pressure tube 10 moves downward with the arc panel 13, and the slider 11 compresses the spring 12 until the end of the L-shaped push plate 14 contacts the housing of the switch button element 2. At this point, the wire-locking groove 15 at the end of the L-shaped push plate 14 snaps into the connecting wire 5, cooperating with the L-shaped push plate. The end sidewall of 14 engages with the sidewall of the embedded ring 7, thereby preventing the connecting wire 5 from being pulled and causing the wiring contact plate 6 to detach from the wiring contact 4. At the same time, the pressure tube 10 presses down against the wiring contact plate 6 to ensure stable contact between the wiring contact plate 6 and the wiring contact 4. At this time, the damping shaft 17 and the clamping plate 18 have passed through the through hole 16. Then, the damping shaft 17 is rotated 180 degrees until the sidewall of the clamping plate 18 engages with the sidewall of the protrusion 20 and the elastic buckle 21 engages with the buckle groove 19, fixing the position of the clamping plate 18. At this time, the bottom wall of the clamping plate 18 engages with the end of the L-shaped push plate 14 to fix the position of the L-shaped push plate 14, completing the wiring. The operation is simple and does not require auxiliary tools, realizing the quick wiring of the switch button element 2 of the marine magnetic starter.
