Embodiment approach 1

[0023] 1 is an exploded perspective view showing an external operating handle device of a switch according to Embodiment 1 of the present invention, figure 2 It is a partial cross-sectional side view showing the state in which the external operating handle device is mounted on the switch. FIG. 3 is an explanatory view showing the rotary handle part of the external operating handle device. Front view, (b) is the right side view, (c) is the front view after pulling out the lock plate. Figure 4 It is a plan view showing the state where the intermediate stopper is housed in the cylindrical body of the front panel part.

[0024] In Figure 1 to Figure 4 Among them, the external operating handle device 101 of the switch is roughly composed of a rotary handle part 1 , a front panel 2 , an intermediate frame 3 , a slider 4 , a torsion spring 5 and a main frame 6 . The external operating handle device 101 of the switch is as figure 2 As shown, it is fixed on a switch 102 such as a ...

Embodiment approach 2

[0082] Figure 8 It is a side view of the main part of the external operation handle device of the switch which concerns on Embodiment 2 of this invention. In Embodiment 1, the intermediate stopper 21 is inserted into the through hole of the cylindrical body 20 in the approximate center of the frame part 22, but the shapes of the intermediate stopper 21 and the frame part 22 are not limited to this, such as Figure 8 As shown, instead of adopting the central method, the frame part 22 may be divided into an upper frame 23 and a lower frame 24, and the upper frame 23 may be mounted on the lower frame 24 at an interval of 90 degrees. In this case, the upper frame 23 constitutes the locking position setting unit, and of course, on its surface, the guide groove 21d, the first to third guide grooves 21e to 21g, 1 to 3 shielding walls 21c1 to 21c3. Other structures are the same as those in Embodiment 1. According to the second embodiment, the external operating handle device of th...

Abstract

The invention provides a peripheral operating handle of switch, with OFF locking preventing function on main contact depositing wherein the ON/OFF locking and OFF locking is corresponding with one structure. The invention comprises a locking parts (14) formed by being pulled out from the operating handle (11), and a locking position setting unit (21) against the operating handle, the relative angle position using axle center of rotation axis (11a) as center is variable. The locking position setting unit is connected with the said locking parts (14) when the relative angle position is at preset position to prevent the operating handle from rotating. The relative angle position between the said operating handle (11) and the locking position setting unit (21) and the switch (102) using the axle center of rotation axis (11a) as center can alter in response of the mounting direction of the switch relative to the said shell.

Description

technical field [0001] The present invention relates to an external operating handle device of a switch for operating a switch such as a circuit breaker for wiring or an earth leakage circuit breaker mounted on a control panel or the like from the outside of the front surface of the control panel or the like. Background technique [0002] Currently, it is known that when a circuit is opened and closed by a switch (hereinafter simply referred to as a switch) such as a circuit breaker for wiring or an earth leakage circuit breaker, in order to keep the circuit open (hereinafter referred to as OFF) or closed (hereinafter referred to as ON) state, for example, a handle locking device is installed on the flip-type handle of the shutter to lock the shutter in the OFF position or the ON position to restrict the operation of the shutter. It is used, for example, to restrain the switch in the OFF position to ensure the safety of the inspection work of the load side circuit of the swi...
