Description

Technical Field

[0001] The present invention relates to the technical field of plugs, in particular to a leakage protection plug structure. Background Art

[0002] With the increasing popularity of household appliances, people are paying more and more attention to the safety of their use. At present, many household appliances are equipped with leakage protection plugs at the input end of the power supply.

[0003] A leakage protector, also known as a leakage switch or leakage circuit breaker, is mainly used to protect equipment from leakage faults and to protect people from fatal electric shock. It has overload and short-circuit protection functions and can be used to protect lines or motors from overload and short circuit. It can also be used as an infrequent switching starter for lines under normal circumstances.

[0004] However, the existing leakage protection plug structure has the following shortcomings: 1) When a short circuit occurs in the plug during use, the temperature of the plug blade becomes too high, causing the plastic shell material at the base of the plug blade to melt or deform, or even catch fire, posing a safety risk to the product and causing personal injury or property damage.

[0005] 2) The existing plug's wiring harness is only fixed to the base of the plug through a wiring harness protector, without a secondary fixing structure. After long-term use, the wiring harness may fall off, making it unusable.

[0006] 3) After long-term use, the screws will rust when exposed to water because there is no protective structure designed for them. This will make it difficult to remove the screws for maintenance later.

[0007] Therefore, we propose a leakage protection plug structure to solve the above problems. Summary of the Invention

[0032] The working principle of the whole device is as follows: when in use, the line is passed through the harness protection head 4 and fixed on the top of the spring piece 524, and then the plug A539 is slid into the grounding connecting piece 536 through the groove C537, and at this time the stop block 538 is embedded in the top of the grounding connecting piece 536 through the groove C537, and then the grounding connecting piece 536 is placed inside the fixing seat 532 through the groove B535, and is placed on the right side of the tripping seat 511 through the limit plate 540, and finally the fixing seat 532 is aligned with the bottom end of the tripping seat 511 and pressed upward, so that the support rod B533 drives the fixing block B534 to slide upward through the clamping ring 531, and when the fixing block B534 completely slides out of the clamping ring 531, the fixing block B534 is detachable. 34 Fix the fixing seat 532 to the bottom end of the trip seat 511 through the support rod B533, and then match the resistor 529 to the fixing plate 527 and press upward to make the resistor 529 slide upward through the fixing plate 527. When the resistor 529 completely slides over the side block 528, the side block 528 can fix the resistor 529 to the bottom end of the trip seat 511. Finally, place the magnetic ring 508 on the top of the trip seat 511, and match the trip seat 511 to the circuit board 501 and press upward to make the support rod A512 drive the fixing block A513 to slide upward through the positioning groove A510. When the fixing block A513 completely slides over the positioning groove A510, the fixing block A513 can fix the trip seat 511 through the support rod A512. 11 is fixed to the bottom end of the circuit board 501. At this time, pin B530 is connected to pin A509 and to the spring piece 524. Then, the wiring harness corresponds to the upper turn block 9 and is pressed downward, so that the turn block 9 rotates downward on the surface of the turn rod 8 through the turn slot 10, and at this time, the turn block 9 rotates inside the connecting rod 6 through the adjustment slot 7. When the wiring harness is pressed in the middle of the connecting rod 6, the card pin 11 on the inner wall of the turn block 9 can fix the wiring harness to the right side of the bottom cover 107 for the second time, and at this time, the wiring harness protection head 4 slides downward on the top of the bottom cover 107 through the limit slot B3, and the plug A539 slides out of the bottom end of the bottom cover 107 through the installation slot 109 through the plug B541, and then the top cover 101 can be pinched and pressed down. Make the fixing rod 104 correspond to the upper support column B110, and make the fixing rod 104 slide downward on the top of the support column B110 through the fixing slot 111. After the card plate A106 slides into the interior of the bottom cover 107 through the card slot A108, and the top cover 101 slides downward on the top of the wiring harness protection head 4 through the limiting slot A2, when the top cover 101 completely slides on the surface of the wiring harness protection head 4 through the limiting slot A2, and at this time, the circuit board 501 is fixed to the inside of the top cover 101 by the support block 102, and the support column A103 presses the circuit board 501, and then the screw 113 is rotated through the groove A112 corresponding to the upper thread groove 105, so that the screw 113 is rotated upward at the bottom end of the fixing rod 104 through the thread groove 105.When the screw 113 is completely turned into the interior of the fixing rod 104 through the thread groove 105, the top cover 101 is firmly fixed to the top of the bottom cover 107 to complete the fixation of the plug assembly 1. Then pinch the protective cover 16 to match the card plate B14 with the card slot B13 and press upward so that the card plate B14 drives the card pad 15 to slide upward at the bottom end of the bottom cover 107 through the card slot B13. When the card plate B14 completely slides out of the interior of the bottom cover 107 through the card slot B13, it is ok. At this time, the card pad 15 will push the card plate B14 through the card slot B13 is fixed to the bottom end of the bottom cover 107, and the protective cover 16 is completely embedded in the bottom end of the bottom cover 107 through the groove D12. When a short circuit occurs during use, the resistor 529 in the leakage protection component 5 can activate the magnetic ring 508, so that the magnetic ring 508 attracts the connecting pin 518 under its own magnetic force, so that the connecting pin 518 slides inside the pressure arm 514 through the sliding groove 516, and drives the locking piece 517 to slide together, so that the locking piece 517 slides into the interior of the reset rod 503 through the inclined groove 504, and At this time, the spring B521 slides outward inside the trip coil 522 through the receiving groove 523, and drives the iron core 520 to slide together through the block 519, so that the locking piece 517 is separated from the connector 542 at the top of the plug-in B, completing the effect of cutting off the circuit. After the diagnosis is completed, the pressing block 506 can be pressed downward to make the pressing block 506 slide downward through the baffle 505. At this time, the reset rod 503 slides downward on the top of the circuit board 501 through the slide groove A502 and is released through the slide groove B515. The top of the pressing arm 514 slides downward, and at this time, the reset rod 503 pushes the locking piece 517 outward through the inclined slot 504, so that the locking piece 517 contacts the connector 542 again. The contact 526 fixed to the top of the spring piece 524 through the hole slot 525 contacts the bottom of the connector 542 again, allowing it to be used normally. When the pressing is completed, the elastic force of the spring A507 itself can drive the pressing block 506 to slide upward through the baffle 505 to complete the reset, making it more convenient for next use.
