Embodiment Construction

[0026] figure 1 Schematically shows an assembled perspective view of the switch operating device 100 according to an embodiment of the present invention, which includes figure 2 Shown cam 110, image 3 The shown spring mechanism 120, Figure 4 The drive rod 130 is shown as well as the Figure 5 Housing 140 is shown.

[0027] figure 2 A perspective view of the cam 110 is schematically shown, wherein the cam 110 includes a cam body 111 and two sliders 115 separated from the cam body 111 . After the switch operating device 100 is installed in place, the slider 115 is installed in the groove 116 of the cam body 111, and has a gap 117 with the cam body 111 (see figure 1 ). On the cam main body 111, two contact areas 112 and two drive areas 113 are arranged on both sides of the camshaft, and guide pins 114 ( figure 2 Only two of the guide pins are marked in ). The end face of the camshaft has a groove for fitting the shaft of an adjacent module (not shown). Those skilled...

Abstract

The invention relates to a switch operating mechanism, which comprises a cam, a spring mechanism and a driving rod, wherein the cam is provided with a cam shaft, two driving regions and two contact regions, the two driving regions and the two contact regions are respectively arranged at two sides of the cam, the end surface of the cam shaft is used for being matched with a shaft of an adjacent module, the spring mechanism comprises a press block and a spring and is pressed and leant against the contact regions of the cam, one end of the driving rod is provided with a projected block, and the projected block can push one driving region of the cam, so the cam is promoted to rotate around the cam shaft. The switch operating mechanism has the advantages that the structure is compact, stable and reliable, the occupied space is small, and the switch operating mechanism is particularly suitable for switches with high rated power.

Description

technical field [0001] The invention relates to a switch operating device, in particular to a switch operating device used in the field of low-voltage electrics. Background technique [0002] The switch operating device in the low-voltage electrical field can be used to control the opening or closing of the circuit, and has a quick opening or closing function to minimize the impact of the arc. Such switch actuating devices usually have a modular design, and the end faces of the shafts can be matched with the shafts of adjacent switching modules, so that the corresponding switching modules can be opened or closed by actuating the switching actuating device. [0003] Chinese patent CN100538949C discloses a switch operating device, which has an actuator and two springs connected to the actuator, and has three positions, namely a circuit disconnected position, a circuit closed position, and a test position. The switch is operated by turning the actuator, and the two springs urg...
