Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic drive switches, and in particular to an alternating switch system and a switch alternation method thereof. Background Art

[0002] The electromagnetic drive switch electrical appliances widely used at present use a group of contacts to break a power supply circuit when working, including electromagnetic relays, AC contactors, etc., which are circuit switch control devices. Usually used in automated control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. It plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit. It is generally composed of an iron core, a coil, an armature, a contact spring, etc. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, thereby generating an electromagnetic effect. The armature will overcome the pulling force of the reaction spring under the action of electromagnetic attraction and be attracted to the iron core, thereby driving the moving contact of the armature and the static contact (normally open contact) to attract. When the coil is powered off, the electromagnetic attraction also disappears, and the armature will return to its original position under the reaction force of the spring, so that the moving contact and the original static contact (normally closed contact) are released. In this way, the attraction and release achieve the purpose of conduction and disconnection in the circuit. The prior art generally integrates these three systems. Its advantages are high integration and easy processing. The disadvantage is that the contacts cannot work alternately, the contacts have accumulated temperature, and the service life of the electromagnetic drive switch electrical appliance is reduced. Summary of the invention

[0003] The object of the present invention is to overcome the deficiencies of the prior art and to provide an alternating switch system and a switching alternation method thereof, wherein the contacts can work alternately.

[0004] The technical solution of the present invention is as follows:

[0005] An alternating switch system comprises a contact structure, a spring, a rotating structure, a slide groove, a push rod, a sliding device and a trigger device, wherein the rotating structure is arranged on the contact structure through a spring and is combined with the contact structure, the push rod is slidably arranged on the slide groove corresponding to the rotating structure, and slides against the trigger device through the sliding device, a first inclined groove is provided at the end of the push rod corresponding to the rotating structure, the slide groove is provided with a second inclined groove and a guide groove, the bottom of the first inclined groove of the push rod is engaged within the highest point of the second inclined groove of the slide groove, and a third inclined groove is provided on the rotating structure corresponding to the first inclined groove of the push rod.

[0006] Furthermore, the contact structure is evenly distributed with metal moving pieces, the switch body is fixed with metal static pieces, one end of the metal static piece is connected to the wire, and the other end of the metal static piece is used to contact and communicate with the metal moving piece.

[0007] The switching alternation method of the alternating switching system includes the following steps:

[0008] 1) When the sliding device and the trigger device touch each other in the vertical direction, a horizontal force is generated;

[0009] 2) The force causes the push rod to move along the slide groove toward the rotating structure, and pushes the rotating structure to move together;

[0010] 3) When the sliding distance reaches the end of the slide slot, the spring is compressed to generate a force that acts on the rotating structure;

[0011] 4) The third inclined groove on the rotating structure and the first inclined groove of the ejector rod act to cause the rotating structure to move along the first inclined groove of the ejector rod. At this time, the rotating structure and the contact structure rotate slightly, and the rotating structure reaches the bottom of the first inclined groove of the ejector rod.

[0012] 5) When the sliding device gradually separates from the trigger device, the compression force generated by the spring pushes the rotating structure and the push rod to move toward the direction of the trigger device;

[0013] 6) When the third inclined groove of the rotating structure contacts the second inclined groove of the slide slot, the compression force generated by the spring pushes the rotating structure to move along the second inclined groove of the slide slot. At this time, the rotating structure and the contact structure rotate significantly and gradually push the ejector rod to move in the direction of the trigger device.

[0014] 7) When the contact structure rotates, the metal moving piece and the metal static piece are disconnected, thereby disconnecting the contact;

[0015] 8) When the rotating structure falls into the guide groove of the slide slot, the rotation stops, and the rotating structure continues to push the push rod to move along the guide groove of the slide slot until it returns to the initial state;

[0016] 9) When steps 1) to 6) are repeated for the next time, the contact structure rotates to make the metal moving piece and the metal static piece contact and connect, thereby the contact is connected.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the present invention can perform alternating operation of contacts, there is no temperature accumulation phenomenon at the contacts, and the contact life of the electromagnetically driven switch electrical appliance can be increased by more than 2 to 3 times.

[0026] The rotating structure 3 is arranged on the contact structure 1 through the spring 2 and is combined with the contact structure 1. The spring 2 can provide a reset force for the rotating structure 3. When the rotating structure 3 rotates, it will drive the contact structure 1 to rotate together. Figure 3 As shown, metal moving pieces 11 are evenly distributed on the contact structure 1, and a metal static piece 8 is fixed on the switch body. One end of the metal static piece 8 is connected to the wire 9, and the other end of the metal static piece 8 is used to contact and communicate with the metal moving piece 11; wherein, the metal moving piece 11 is combined with the contact structure 1 and can rotate with the contact structure 1; the metal static piece 8 is a fixed part and does not rotate with the contact structure 1.

At this time, the rotating structure 3 and the contact structure 1 rotate slightly, and the rotating structure 3 reaches the bottom of the first inclined groove of the ejector 5.

[0033] 5) When the sliding device 6 gradually separates from the trigger device 7, the compression force generated by the spring 2 pushes the rotating structure 3 and the push rod 5 to move toward the direction of the trigger device 7;

[0034] 6) When the third inclined groove of the rotating structure 3 contacts the second inclined groove of the slide groove 4, the compression force generated by the spring 2 pushes the rotating structure 3 to move along the second inclined groove of the slide groove 4. At this time, the rotating structure 3 and the contact structure 1 rotate significantly and gradually push the ejector rod 5 to move in the direction of the trigger device 7;

[0035] 7) When the contact structure 1 rotates, the metal moving piece 11 is disconnected from the metal static piece 8, thereby disconnecting the contact;

[0036] 8) When the rotating structure 3 falls into the guide groove of the chute 4, the rotation stops, and the rotating structure 3 continues to push the push rod 5 to move along the guide groove of the chute 4 until it returns to the initial state;

[0037] 9) When steps 1) to 6) are repeated for the next time, the contact structure 1 rotates to make the metal moving piece 11 contact and communicate with the metal static piece 8, thereby connecting the contacts, and the cycle repeats to form an alternating action of the switch.
