Abstract

The present invention relates to the field of low-voltage electric appliances, and more particularly, to an operating device and a switching device including the operating device. In the operating device, a rotating shaft, a connecting rod, and a driving shaft are all coaxially and rotatably arranged around an axis s-s. When the operating device is in a closed / opened state, the rotating shaft is at a first / second position, and the connecting rod is at a third / fourth position. The rotating shaft rotates from the first or second position to an intermediate position, so that an energy storage structure stores energy, and the connecting rod remains stationary during energy storage. When the rotating shaft is at the intermediate position, the energy storage structure can store maximum energy; and after rotating through the intermediate position, the energy storage structure releases energy and drives the rotating shaft and the connecting rod to rotate relative to each other. The driving shaft and the connecting rod are synchronously and rotatably arranged, and the driving shaft is transmittingly connected to a main contact support to drive the main contact support to linearly move in an extending direction of the axis s-s. The operating device has a simple structure, increases a rotation angle of the connecting rod, and reduces a space required for the movement of the main contact support; and when the operating device is applied to the switching device, the electrical performance of the switching device can be improved, and the specification and dimension of the switching device can also be reduced.

In abnormal opening, for example, the movable contact 5-1 and the static contact 6-00 are welded and cannot be separated, the first limiting portion 1-4 and the second limiting portion 5-016 are clamped with each other to limit the rotation of the rotating shaft 1, so that the rotating shaft 1 cannot rotate to the second position, thereby realizing the warning to the operator, prompting the operator that the movable contact 5-1 and the static contact 6-00 cannot be separated, and further improving the safety of the operator during operation. In addition, it should be pointed out that the reason for abnormal opening may also be that the main contact support 5-0 is blocked (for example, the shell structure is deformed or damaged to block the movement of the main contact support 5-0) and cannot move, thereby cannot drive the movable contact 5-1 and the static contact 6-00 to disconnect.

[0170] Specifically, as shown in FIGS. 29-31, the driving shaft first insertion hole 4-0b of the driving shaft 4 is a through hole which at least partially coincides with or is in relative communication with the moving path of the second limiting part 5-016, that is, the first limiting part 1-4 and the second limiting part 5-016 need to pass through the driving shaft first insertion hole 4-0b to realize cooperation: the first case is that, as shown in FIGS. 29-30, one end of the rotating shaft 1 (the end of the rotating shaft 1 opposite to the main contact support 5-0) is provided with the first limiting part 1-4 and the end of the rotating shaft 1 is rotatably inserted into one end of the driving shaft first insertion hole 4-0b - specifically, the lower end of the rotating shaft 1 is provided with the first limiting part 1-4 and the lower end of the rotating shaft 1 is rotatably inserted into the upper end of the driving shaft first insertion hole 4-0b, the driving shaft first insertion hole 4-0b partially coincides with the moving path of the second limiting part 5-016 - specifically, the lower end of the driving shaft first insertion hole 4-0b coincides with the moving path of the second limiting part 5-016, and the second limiting part 5-016 moves into and out of the driving shaft first insertion hole 4-0b. The second case is that one end of the rotating shaft 1 (the end of the rotating shaft 1 opposite to the main contact support 5-0) is provided with the first limiting part 1-4 and the end of the rotating shaft 1 protrudes outside one end of the driving shaft first insertion hole 4-0b by passing through the driving shaft first insertion hole 4-0b - specifically, the lower end of the rotating shaft 1 is provided with the first limiting part 1-4 and the lower end of the rotating shaft 1 protrudes outside the lower end of the driving shaft first insertion hole 4-0b by passing through the driving shaft first insertion hole 4-0b, and the second limiting part 5-016 is always located outside one end of the driving shaft first insertion hole 4-0b. The third case is that one end of the rotating shaft 1 (the end of the rotating shaft 1 opposite to the main contact support 5-0) is provided with the first limiting part 1-4, the first limiting part 1-4 is opposite to one end of the driving shaft first insertion hole 4-0b, and the second limiting part 5-016 is slidably arranged in the driving shaft first insertion hole 4-0b. In this embodiment, the first case is preferably adopted to realize.

[0171] Specifically, as shown in FIG. 29, among the first limiting part 1-4 and the second limiting part 5-016, one includes at least one limiting boss, and the other includes at least one limiting groove; the switch device / operation device is in the closed state, and the limiting boss is located in the limiting groove; when normally opening, the rotating shaft 1 is driven by the driving shaft 4 to drive the main contact support 5-0 to move to separate the limiting boss from the limiting groove, so as to allow the rotating shaft 1 to continue to rotate to the second position. When abnormally opening, after the rotating shaft 1 is driven by the first position to pass through the intermediate position, the main contact support 5-0 is limited and cannot move, and the rotating shaft 1 is limited by the limiting boss and the groove wall of the limiting groove during the rotation to the second position (clamping), thereby preventing the rotating shaft 1 from rotating to the second position. Further, the first limiting part 1-4 includes two limiting bosses, and the two limiting bosses are oppositely arranged along the radial direction of the rotating shaft 1. The second limiting part includes two limiting grooves, and the two limiting grooves are oppositely arranged along the radial direction of the rotating shaft 1. The two limiting bosses are correspondingly matched with the two limiting grooves. Further, the main contact support 5-0 is provided with a matching column 5-015, one end of the matching column 5-015 is provided with a second limiting part 5-016, and the other end is connected with the support bearing part 5-01. Further, the matching column 5-015 is arranged between the two support driven parts 5-00, and the matching column 5-015 and the support driven part 5-00 are arranged side by side and spaced apart.

[0172] As shown in FIGS. 32-33, another main difference between the switch device of the present embodiment and the switch device of the first embodiment is the matching structure of the main body shell h and the main contact support 5-0. Specifically, the main contact support 5-0 is further provided with a first protruding rib 5-03, and the first protruding rib 5-03 is arranged between adjacent contact systems. The contact cavity separation wall of the base h-2 is further provided with a second protruding rib h-29. The first protruding rib 5-03 and the second protruding rib h-29 are one-to-one matched, which is used to separate the adjacent contact cavities h-28, thereby improving the insulation of the adjacent contact systems.

[0173] Specifically, the first convex ribs 5-03 and the corresponding second convex ribs h-29 are arranged in a stacking manner and in sliding fit along the side-by-side direction of the movable contact 5-1. Further, in the direction of the axis s-s, the size of the second convex ribs h-29 is greater than that of the first convex ribs 5-03, so that the first convex ribs 5-03 and the corresponding second convex ribs h-29 always remain at least partially overlapped in the side-by-side direction of the movable contact 5-1. Further, in the projection direction of the switch device, the first convex ribs 5-03 and the one end of the auxiliary guide rail 5-02 adjacent to each other overlap on the orthogonal projection of the side-by-side direction of the movable contact 5-1, thereby further improving the insulation between adjacent contact systems. Further, the support movable part 5-00 of the main contact support 5-0 is provided with the first convex ribs 5-03 on both sides; the second convex ribs h-29 are arranged on a pair of side walls of the partition wall avoiding groove; and the two groups of first convex ribs 5-03 and the two groups of second convex ribs h-29 are correspondingly matched.
