[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 10A live safety wiring switch includes a boat-type switch 1, on which a guide frame 2, a movable plate 3, a contact plate 4, a magnetic sealing strip 5, a guide hole 6, a pressure plate 7, a reset mechanism 8 and a locking mechanism 10 are arranged. The components are arranged as follows: Reference Figure 1 With attached Figure 7 The guide frame 2 corresponding to the pin of the rocker switch 1 is slidably mounted on the rocker switch 1. The rocker switch 1 is provided with a guide groove for slidingly mounting on the guide frame 2. The guide frame 2 is a hollow plate structure with an open upper end. Two adjacent guide frames 2 are arranged opposite to each other on both sides of the pin of the rocker switch 1. It should be noted that the rocker switch 1 has three pins, and the guide frames 2 are provided with six pins, and every two guide frames 2 form a group.

[0023] Reference Figure 3 The movable plate 3 is slidably mounted in the guide frame 2, and a limited sliding groove is provided on the guide frame 2. A limited sliding block slidably connected to the limited sliding groove is fixedly connected to the movable plate 3 to prevent the movable plate 3 from separating from the guide frame 2. The contact plate 4 is fixedly connected to the guide frame 2, and the contact plate 4 occupies the place of the guide frame 2 not occupied by the movable plate 3, so that the two guide frames 2 will fully guide and cover the periphery of the ends of the live wire, the neutral wire and the load wire after the two guide frames 2 are fitted together. The magnetic sealing strip 5 is fixedly connected to the guide frame 2 and the contact plate 4, and the magnetic force generated by the magnetic sealing strip 5 is used to achieve a close fit between the two guide frames 2 and the two contact plates 4, which helps to ensure that dust will not enter the interior of the two guide frames 2 and the two contact plates 4 through the gap between them, causing a negative impact on the service life of the live wire, the neutral wire and the load wire.

[0024] A guide hole 6 for guiding and limiting the neutral wire, the load wire and the live wire is provided on the contact plate 4. The guide hole 6 is a semicircular hole structure. A semi-annular rubber gasket is fixedly provided on the inner wall of the guide hole 6. The neutral wire, the load wire and the live wire body are guided and covered by the annular rubber gasket, thereby preventing dust from entering the guide frame 2 through the guide hole 6 and causing a negative impact on the service life of the neutral wire, the load wire and the live wire.

[0025] Based on the setting of the contact plate 4, in order to ensure the stability of the neutral wire, the load wire and the live wire after they are plugged in, a pressure plate 7 is installed on the pin shaft of the contact plate 4, and a reset mechanism 8 is set between the contact plate 4 and the pressure plate 7 for assisting the pressure plate 7 to reset when it is not affected by external force. A rubber pad is fixedly set on the side of the pressure plate 7 away from the reset mechanism 8, so that the pressure plate 7 will not have rigid contact with the neutral wire, the load wire and the live wire end when it is contacted and limited by the three, which helps to prevent the pressure plate 7 from causing damage to the neutral wire, the load wire and the live wire end.

[0026] A further implementation method is that the reset mechanism 8 includes a receiving slide groove 801, a driving slider 802, a first reset spring 803, a traction rod 804 and a working chamber 9, and each component is arranged as follows: The storage slot 801 is opened on the pressure plate 7, the driving slider 802 is slidably mounted in the storage slot 801, the first return spring 803 is welded between the driving slider 802 and the storage slot 801, and the two ends of the traction rod 804 are pin-connected to the contact plate 4 and the driving slider 802 respectively. It should be noted that: after the pressure plate 7 is deflected by the impact of the neutral line, the load wire and the end of the live wire, the first return spring 803 is in a compressed state at this time. Under the elastic force of the first return spring 803, the driving slider 802 moves toward the initial state. Therefore, the pressure plate 7 will continue to squeeze and limit the neutral line, the load wire and the end of the live wire, further ensuring the stability of the live wire, the neutral line and the load wire after plugging.

[0027] Based on the arrangement of the movable plate 3 and the guide frame 2, in order to change the motion state of the movable plate 3 when it is located in the guide frame 2, a working cavity 9 is opened at the lower end of the movable plate 3, and a locking mechanism 10 is arranged in the working cavity 9; Further implementation method is that the locking mechanism 10 includes a leaf spring 1001, a connecting rod 1002, a limiting hole 1003, a bracket 1004, a limiting column 1005, a force plate 1006, a second return spring 1007, a mounting rod 1008, a pivot arm 1009 and a conflicting tooth 1010, and each component is arranged as follows: Both ends of the leaf spring 1001 are fixedly connected to the top wall of the working chamber 9, the lower end of the connecting rod 1002 is fixedly connected to the leaf spring 1001, the upper end of the connecting rod 1002 passes through and extends to the position above the movable plate 3, and a long limiting hole for sliding the connecting rod 1002 is opened on the movable plate 3, and a handle is set at the top of the connecting rod 1002.

[0028] The limiting hole 1003 is opened on the connecting rod 1002, the bracket 1004 is fixedly connected to the top position of the movable plate 3, and the limiting column 1005 corresponding to the level of the limiting hole 1003 is slidably mounted on the bracket 1004. It should be noted that: when the limiting column 1005 is located in the limiting hole 1003, the leaf spring 1001 is in a deformed state, and when the limiting column 1005 is away from the limiting hole 1003, the leaf spring 1001 is in an undeformed state, the force plate 1006 is fixedly connected to the limiting column 1005 on one end away from the bracket 1004 and the connecting rod 1002, the second reset spring 1007 is fixedly connected between the bracket 1004 and the force plate 1006, and the second reset spring 1007 is movably mounted on the limiting column 1005, and the elastic force of the second reset spring 1007 is utilized to enable the force plate 1006 to be reset when not affected by external force.

[0029] The mounting rod 1008 is fixedly connected to the top wall of the working chamber 9, and the pivot arm 1009 is movably installed between the mounting rod 1008 and the leaf spring 1001. Two pivot arms 1009 are provided, and the abutting teeth 1010 are provided on the inner walls of both sides of the guide frame 2; It should be noted that the pivot arm 1009 includes a transverse rod 10091, an L-shaped rod 10092 and a locking tooth 10093, and each component is arranged as follows: The transverse rod 10091 is movably installed between the mounting rod 1008 and the leaf spring 1001. It should be noted that the connection between the transverse rod 10091 and the leaf spring 1001 is a sliding connection, the connection between the transverse rod 10091 and the mounting rod 1008 is a hinged connection, the L-shaped rod 10092 is integrally connected to the end of the transverse rod 10091 close to the mounting rod 1008, and the locking tooth 10093 corresponding to the interference tooth 1010 is fixedly connected to the lower end of the L-shaped rod 10092. When the locking tooth 10093 is in conflict with the interference tooth 1010, the movable plate 3 is located in the guide frame 2 in a statically fixed state, and when the locking tooth 10093 is not in conflict with the interference tooth 1010, the movable plate 3 is located in the guide frame 2 in an active state.

[0030] The present invention can be explained by the following operation mode: Plug the live wire, the neutral wire and the load wire into the corresponding pins of the boat-type switch 1, pull the movable plate 3 to move outward from the guide frame 2, pull the force plate 1006, so that the limit column 1005 is away from the limit hole 1003, and stretch the second reset spring 1007. At this time, the limit column 1005 no longer locks the connecting rod 1002. Under the elastic force of the leaf spring 1001, the leaf spring 1001 drives the connecting rod 1002 to move downward, and the leaf spring 1001 drives the transverse rod 10091 to deflect downward. The transverse rod 10091 drives the L-shaped rod 10092 to deflect upward based on the lower end of the installation rod 1008, and the L-shaped rod 10092 drives the locking tooth 10093 to contact and limit with the interfering tooth 1010, so that the movable plate 3 is fixed in the guide frame 2; The two guide frames 2 are pushed to fit inward, and the magnetic sealing strip 5 is used to ensure the tightness between the guide frame 2 and the contact plate 4. The connecting rod 1002 is pulled, and the connecting rod 1002 drives the leaf spring 1001 to undergo elastic deformation. The leaf spring 1001 drives the transverse rod 10091 to deflect upward, and the transverse rod 10091 drives the L-shaped rod 10092 to deflect downward, so that the locking tooth 10093 is away from the contact tooth 1010, and the force plate 1006 is released. Under the elastic force of the second return spring 1007, the force plate 1006 drives the limiting column 1005 to enter the limiting hole 1003, so as to complete the limiting operation of the limiting column 1005 on the connecting rod 1002. At this time, the movable plate 3 slides in the guide frame 2, pushing the movable plate 3 and the contact plate 4, so that the contact plate 4 and the guide frame 2 are movable against each other; The pressing plate 7 is deflected upward by the impact of the live wire, the neutral wire and the end of the load wire, so that the traction rod 804 is deflected upward, and the traction rod 804 drives the driving slider 802 to move in the receiving slide groove 801 toward the end of the live wire, the neutral wire and the load wire, squeezing the first return spring 803; When it is necessary to unplug the live wire, the neutral wire and the load wire, pull the movable plate 3 and the contact plate 4 to move outward from the guide frame 2, pull the force plate 1006, so that the limit column 1005 is away from the limit hole 1003, and stretch the second reset spring 1007. At this time, the limit column 1005 no longer locks the connecting rod 1002, and under the elastic force of the leaf spring 1001, the leaf spring 1001 drives the connecting rod 1002 to move downward, and the leaf spring 1001 drives the transverse rod 10091 to deflect downward, and the transverse rod 10091 drives the L-shaped rod 10092 to move upward based on the lower end of the mounting rod 1008. Deflection, the L-shaped rod 10092 drives the locking tooth 10093 to contact and limit with the interfering tooth 1010, so that the movable plate 3 is fixed in the guide frame 2. At this time, the pressure plate 7 no longer contacts with the ends of the live wire, the neutral wire and the load wire. Under the elastic force of the first reset spring 803, the driving slider 802 is reset in the storage slide groove 801, and the driving slider 802 drives the traction rod 804 to deflect downward. Under the guidance of the guide frame 2, the live wire, the neutral wire and the load wire are pulled out, which helps to ensure that the pull-out angle of the live wire, the neutral wire and the load wire is consistent with the placement angle of the pins of the rocker switch 1; When the live wire, neutral wire and load wire are away from the pin of the rocker switch 1, the guide frame 2 is pulled apart to separate the two guide frames 2 from the pin of the rocker switch 1, so that the staff can remove the live wire, neutral wire and load wire easily.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
