Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a linkage status display isolating switch. Background Technology

[0002] As its name suggests, a disconnecting switch serves to isolate circuits. Its working principle and mechanism are relatively simple. In low-voltage equipment, disconnecting switches are mainly used in low-voltage terminal power distribution systems such as residential buildings and other buildings. Main functions: disconnecting and connecting circuits under load. The internal closing and opening of a disconnecting switch is operated using a handle.

[0003] Existing disconnect switches typically have status indicators attached to the handle, or the handle and indicator are connected by a complex connection structure, so that the current status of the disconnect switch can be determined by observing the status of the handle or indicator.

[0004] However, this method does not clearly display the status, and the existing connection structure is relatively complex, costly, and prone to failure after long-term use, thus affecting subsequent use. Utility Model Content

Figure 1-3 As shown, it includes a base 13, a static contact structure disposed within the base 13, a moving contact structure corresponding to the static contact structure, an indicator 8 linked to the moving contact structure, and a handle 6 for driving the moving contact structure to move; a wiring board 15 is provided inside the base 13, and one end of the moving contact structure is connected to the wiring board 15 through a wire; the handle 6, the moving contact structure, and the indicator 8 are connected through a linkage mechanism; the handle 6 and the indicator 8 are both rotatably disposed on the base 13.

[0026] The base 13 has corresponding slots for the operation of the handle 6 and the indicator 8.

[0027] like Figure 6 and 7 The static contact structure includes a wiring frame 12 located at the corresponding position of the inner end of the base 13, a static contact 10 passing through the top of the wiring frame 12, and a screw 11 passing through the wiring frame 12 and fixing the static contact 10; the static contact 10 is bent upward near the end of the moving contact structure, and static contact points 9 are provided on the end of the static contact 10.

[0028] like Figure 4 and 5 The moving contact structure includes a moving contact 4 that is rotatably fixed in the base 13 at one end, a rotating shaft 1 that passes through the end of the moving contact 4 and is connected to the base 13, and a moving contact 3 located below the other end of the moving contact 4; a reaction spring 2 sleeved on the rotating shaft 1 is provided inside the moving contact 4; and a contact spring 5 is provided inside the moving contact 4.

[0029] The linkage mechanism includes a U-shaped bolt 7 connecting the handle 6 and the moving contact 4, and a connecting rod connecting the indicator 8 and the moving contact 4; the moving contact 4 is provided with a connecting protrusion for installing the connecting rod on its outside, one end of the connecting rod is fixedly connected to the indicator 8, and the other end is provided with a sliding groove corresponding to the connecting protrusion.
