[0002] With the rapid development of the economy and society, the number of electrical equipment in large power-consuming places such as computer rooms, shopping malls, and schools has continued to increase, and the task of reducing the energy consumption of these electrical equipment has become very urgent. There are a huge number of DC power-consuming equipment in these power-consuming places, and most of them are powered by AC. When working, they need to be equipped with AC adapters to convert AC into DC to supply DC power to DC equipment. The conversion efficiency in this process is usually about 80%. In DC power supply, when the plug is plugged in and out of the DC socket, the air gap between the plug and the socket conductor breaks down and generates a high-temperature arc.

[0003] In the prior art, an arc shield is provided on the inner wall of the housing to shield the high-temperature arc, thereby achieving the effect of blocking sparks. However, the arc shield only blocks the high-temperature arc inside, and tries to prevent the high-temperature arc from leaking out, but cannot fundamentally eliminate the impact of the high-temperature arc on the conductive parts, thus affecting the service life. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the arc baffle plate only blocks the high-temperature arc inside and tries to prevent the high-temperature arc from leaking to the outside, but cannot fundamentally eliminate the influence of the high-temperature arc on the conductive parts, thereby affecting the service life, thereby providing an arc-proof switch.

[0010] The barrier member is rotatably arranged, and the barrier member includes a driving part and a barrier part. The driving part is arranged close to the button, and the barrier part is arranged close to the contact assembly. When the cover plate is pressed, the cover plate drives the button to rotate, and the button acts on the driving part to rotate the barrier member, and the barrier part moves between the moving contact of the moving contact assembly and the static contact of the static contact assembly which are converted from the on state to the off state.

[0011] Furthermore, it also includes a reset member, which acts on the driving part to drive the blocking part to move to the outside of the moving contact and the static contact when the disconnected state is converted to the connected state.

[0012] Furthermore, it also includes a pressing plate, and the button is inserted into the pressing plate; the reset member is an elastic member, one end of the elastic member abuts against the blocking portion and the other end abuts against the installation recessed portion of the pressing plate.

[0013] Furthermore, the elastic member is a return spring, and the return spring is sleeved on the first positioning boss in the installation recess.

[0014] Furthermore, the return spring is also sleeved on the second positioning boss of the driving part.

[0015] Further, the pressing plate is provided with a receiving portion, the receiving portion is located outside the contact assembly, and the resetting member acts on the driving portion to drive the blocking portion to move into the receiving portion.

[0016] Furthermore, the barrier member also includes a rotating shaft, and the rotating shaft is located in the rotating shaft hole of the pressure plate.

[0017] Furthermore, the driving portion and the blocking portion are arranged at an angle, and the rotating shaft is arranged at the angle between the driving portion and the blocking portion.

[0047] The barrier member 6 in this embodiment is rotatably arranged, and the barrier member 6 includes a driving part 61, a barrier part 62 and a rotating shaft hole 81. The driving part 61 is arranged close to the button 4, and the barrier part 62 is arranged close to the contact assembly. When pressure is applied to the cover plate 1, the cover plate 1 drives the button 4 to rotate, and the button 4 acts on the driving part 61 to rotate the barrier member 6, and the barrier part 62 moves to between the moving contact 521 of the moving contact assembly 52 and the static contact 511 of the static contact assembly 51, which are converted from the connected state to the disconnected state.

[0048] like Figure 4 and Fig.14 As shown, the button 4 is provided with an action protrusion 43 on the side facing the driving part 61, and the action protrusion 43 acts on the driving part 61.

[0050] By providing a reset member, when the moving contact 521 and the static contact 511 need to be connected, the reset member resets the blocking portion 62 to be located outside the moving contact 521 and the static contact 511 instead of between the moving contact 521 and the static contact 511, ensuring normal connection between the moving contact 521 and the static contact 511.

[0051] Among them Figures 1 to 10 As shown, the arc-proof switch is an arc-proof double-control switch, with two moving contacts 521 and two static contacts 511. In this case, two barrier members 6 are provided, and two reset members are also provided. Figure 1 In the embodiment, the static contact 511 and the moving contact 521 on the left are in the connected state; Figure 1 In the process, the cover plate 1 is pressed to the left, the cover plate 1 drives the button 4 to rotate, and the moving contact assembly 52 rotates under the action of the push rod 42 in the button 4. At the same time, the barrier 6 also rotates around the rotating shaft hole 81 under the action of the button 4. Figure 2 In the embodiment, the moving contact assembly 52 rotates clockwise, the moving contact 521 on the left side rises and the moving contact 521 on the right side falls, and at the same time, the two barrier members 6 rotate counterclockwise, and the moving contact 521 on the left side and the static contact 511 on the left side are gradually disconnected, and the barrier member 6 on the left side gradually moves to between the moving contact 521 on the left side and the static contact 511 on the left side, cutting off the high-temperature arc generated by the disconnection of the contacts, and the moving contact 521 on the right side and the static contact 511 on the right side are gradually connected, and the barrier member 6 on the right side gradually moves to outside the moving contact 521 on the right side and the static contact 511 on the right side; in the embodiment, the moving contact 521 on the left side and the static contact 511 on the right side are gradually connected, and the barrier member 6 on the right side gradually moves to outside the moving contact 521 on the right side and the static contact 511 on the right side; Figure 3 In the embodiment, the moving contact 521 on the right side is connected to the stationary contact 511 on the right side, and at the same time, the barrier 6 on the left side moves to between the moving contact 521 on the left side and the stationary contact 511 on the left side.

[0052] As well as Figures 11 to 14 As shown, the arc-proof switch is an arc-proof single-control switch, with one moving contact 521 and one static contact 511. At this time, there is one barrier member 6 and one reset member. Fig.11 In the state of connection, the moving contact 521 and the stationary contact 511 are in the connected state; Fig.12 In the process, the cover plate 1 is pressed to the right, and the button 4 rotates clockwise under the drive of the cover plate 1. At this time, the moving contact assembly 52 rotates counterclockwise under the action of the push rod 42 in the button 4, and the moving contact 521 and the static contact 511 are gradually disconnected. At the same time, the barrier 6 also rotates clockwise under the action of the button 4, and the barrier 6 gradually moves to between the moving contact 521 on the left and the static contact 511 on the left, cutting off the high-temperature arc generated by the disconnection of the contacts. Fig.13In the embodiment, the moving contact 521 and the stationary contact 511 are disconnected, and at the same time, the barrier 6 moves to between the moving contact 521 on the left and the stationary contact 511 on the left.

[0053] An arc-proof switch of the present invention is provided with a barrier member 6. When the cover plate 1 is pressed, the cover plate 1 drives the button 4 to rotate. The button 4 acts on the driving part 61 to move the barrier part 62 to between the moving contact 521 and the static contact 511 which are converted from the on state to the off state, so that the barrier part 62 cuts off the high-temperature arc generated by the disconnection of the contacts and extinguishes it, thereby eliminating the influence of the high-temperature arc on the conductive parts, improving the safety performance, and extending the service life.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods.
