Claims

1. An insulation structure for a drawer-type frame switch busbar, characterized in that, An insulating structure is located between the switch body (11) and the drawer seat. The insulating structure includes a first insulating sleeve (15) sleeved on the main body busbar (12) and a second insulating sleeve (16) located on the side of the opening mechanism (17) facing the switch body (11). The switch body (11) has at least a connected position, a test position and a disconnected position. The switch body (11) moves along a first direction from the disconnected position and the test position to the connected position in sequence. When in the connected position, the main body busbar (12) is in the socket (171). When in the test position and the disconnected position, the main body busbar (12) is not in the socket (171). At least when the switch body (11) is in the connected position, the socket (171) is surrounded by the first insulating sleeve (15) and the second insulating sleeve (16) interlocking to form an insulating channel (100).

2. The insulation structure of the drawer-type frame switch busbar according to claim 1, characterized in that, When the switch body (11) is in the test position or in the disengaged position, the insulation channel (100) has been formed.

3. The insulation structure of the drawer-type frame switch busbar according to claim 1, characterized in that, The second insulating sleeve (16) moves along with the switch body (11). An elastic element (18) is provided between the second insulating sleeve (16) and the first insulating sleeve (15). When the switch body (11) is in the separated position, there is a gap between the second insulating sleeve (16) and the door opening mechanism (17). After the switch body (11) moves along the first direction, the second insulating sleeve (16) and the door opening mechanism (17) abut against each other and surround the socket (171), forming an insulating channel (100). As the switch body (11) continues to move along the first direction, relative movement occurs between the first insulating sleeve (15) and the second insulating sleeve (16), and the deformation of the elastic element (18) increases.

4. The insulation structure of the drawer-type frame switch busbar according to claim 3, characterized in that, The second insulating sleeve (16) and the first insulating sleeve (15) are nested together, and there is always an interlocking between them. The interlocking amount when the switch body (11) is in the separated position is less than the interlocking amount when the switch body (11) is in the connected position.

5. The insulation structure of the drawer-type frame switch busbar according to claim 3, characterized in that, One of the first insulating sleeve (15) and the second insulating sleeve (16) is provided with a first positioning post (19), and the other of the first insulating sleeve (15) and the second insulating sleeve (16) is provided with a second positioning post (20). The second positioning post (20) is provided with a second positioning hole (201) that cooperates with the first positioning post (19).

6. The insulation structure of the drawer-type frame switch busbar according to claim 3, characterized in that, An anti-detachment structure is provided between the first insulating sleeve (15) and the second insulating sleeve (16). The anti-detachment structure includes an anti-detachment hole (21) and an anti-detachment protrusion (22). In the moving direction of the main body busbar (12), the anti-detachment hole (21) and the anti-detachment protrusion (22) are restricted from separating. The anti-detachment hole (21) or the anti-detachment protrusion (22) is an elastic structure.

7. The insulation structure of the drawer-type frame switch busbar according to claim 1, characterized in that, The door opening mechanism (17) is provided with a baffle protrusion (172) surrounding the insertion hole (171), and the second insulating sleeve (16) is provided with an annular insulating flange (161) on the side facing the door opening mechanism (17). The insulating flange (161) and the baffle protrusion (172) are interlocked.

8. The insulation structure of the drawer-type frame switch busbar according to claim 1, characterized in that, One end of the second insulating sleeve (16) is always abutted against, connected to, or integrally formed with the door opening mechanism (17), and this end always surrounds the insertion hole (171). The other end of the second insulating sleeve (16) is used to interlock with the first insulating sleeve (15) to form an insulating channel (100).

9. The insulation structure of the drawer-type frame switch busbar according to claim 1, 2, 3, 4, 5, 6, 7, or 8, characterized in that, The first insulating sleeve (15) is fitted onto one end of the main busbar (12) away from the door mechanism (17).

10. The insulation structure of the drawer-type frame switch busbar according to claim 1, characterized in that, The main body (12) is in the shape of a straight line; or, the main body (12) is in the shape of a T; or, the main body (12) is in the shape of a U.
