Embodiment 1

[0036] figure 1 It is a structural diagram of an isolating switch of the present invention. As shown in the figure, the isolating switch includes a drive shaft 10 with a contact portion 11 . The disconnector also includes a disc cam 20 with an opposing boss 23 , the axis of rotation of the disc cam 20 is perpendicular to the axis of the drive shaft 10 . The boss 23 abuts against the elastic member 40 , and the elastic member 40 can reciprocate along the outline of the protrusion 23 according to the rotation of the disc cam 20 . At the same time, the disc cam 20 is provided with a first protrusion 21 and a second protrusion 22, and the two protrusions 21 and 22 can respectively contact the contact part 11 in the on / off state of the isolating switch.

[0037] figure 2 yes figure 1 An exploded perspective view of the disconnect switch shown. As shown in the figure, a groove 25 is provided on one disc-shaped end surface of the disc-shaped cam 20 . A slider 30 is disposed in ...

Embodiment 2

[0054] Figure 9 is a structural schematic diagram of another isolating switch of the present invention, and its structure is similar to that of the isolating switch described in Embodiment 1. The same structure and function of the isolating switch shown in Embodiment 1 will not be repeated here, and only the differences between the two will be described.

[0055] For the convenience of expression, the disc cam in this embodiment is marked as 50, and a first bump 51 and a second bump 52 are arranged on it. During operation, the two protrusions 51 or 52 of the disk cam 50 contact the contact portion 11 of the drive shaft 10, thereby changing the on / off state of the disconnector. A groove 55 is provided on a disk-shaped end face of the disk cam 50 . Two positioning pins 54 are also arranged in the groove 55 . Such as Figure 9 As shown, a slide block 60 is provided in the groove 55, and the slide block 60 includes a body 61, an operation hole 62 is opened in the middle part ...

Abstract

The invention provides an isolating switch comprising a driving shaft and a disk cam, wherein the driving shaft is provided with a contact part; the disk cam is provided with two opposite bosses; the axis of rotation of the disk cam is vertical to the axis of the driving shaft; the disk cam comprises a first lug, a second lug, a groove and a slide block, wherein the first lug and the second lug are respectively contacted with the contact part under different working states; the groove is arranged on at least one disk end surface of the disk cam; the slide block is arranged in the groove and comprises a body, an operating hole and two wing blocks, wherein the operating hole is positioned in the middle of the body, and the wing blocks are arranged on the two sides of the body; and the slideblock can rotate relative to the groove and can drive the disk cam to rotate. The isolating switch of the invention can be operated from the right side and the side, and side operation is manpower irrelevant operation; and meanwhile, no additional devices are needed.

Description

technical field [0001] The invention relates to an isolating switch, in particular to an isolating switch capable of side operation regardless of manpower. Background technique [0002] A disconnector is a device commonly used in electrical circuits, which can change its on / off state by front or side operation. Generally, front or side operation of disconnectors cannot be replaced. Some products are replaced by front operation or side operation. The side operation is not irrelevant to human operation, that is, the action speed of the mechanism is related to the operation speed of the human hand, or additional devices are required to realize this function, such as adding a side operation shaft or replacing the driving cam. wait. [0003] Chinese Utility Model Patent No. CN2847501Y discloses an isolating switch. The operating device of this isolating switch is completed under the action of spring energy storage, and the opening and closing action is completed by the force of...
