Problems solved by technology

A single L-shaped outlet bar can be in contact with two surfaces of the busbar, and multiple L-shaped busbars can be in contact with multiple surfaces of the busbar, but the distance between the L-shaped and L-shaped outlet bars is fixed at a fixed value, and it cannot be compared with The thickness of the busbar is consistent, which will also cause the same defects as the U-shaped outlet bar
[0007] The above-mentioned several commonly used outlet bar structures, because the position has been fixed in the assembly, cannot be adjusted, and do not have the adjustable operation function when the client is connected to the busbar, resulting in many defects

Embodiment approach 1

[0049] Such as Figure 1 to Figure 9 As shown, the present invention provides an installation and adjustment structure 10 for the outgoing line bar, which is connected between the outgoing line bar 1 and the drawer base 2, and the distance H between the two outgoing line bars 1 of the busbar 3 can be Adjustment is carried out through the installation and adjustment structure 10 of the outlet row; the installation and adjustment structure 10 of the outlet row includes: a bracket 4 connected between the outlet row 1 and the drawer base 2, one end of the bracket 4 It is fixedly connected with the outlet bar 1 , and the other end of the bracket 4 is movably connected with the drawer base 2 . Before the busbar 3 is inserted into the gap between the two outlet bars 1, the initial distance between the two outlet bars 1 can be adjusted to be greater than the thickness of the busbar 3. When the customer is connecting the busbars, it is easier to insert the busbar 3 Between the two out...

Embodiment approach 2

[0064] Such as Figure 1 to Figure 14As shown, the present invention also provides a drawer-type circuit breaker chassis 20, which has a drawer base 2, and the drawer base 2 is connected with a conductive wire-in terminal 24 and a conductive wire-out terminal 25, and the conductive wire-in At least one wire outlet group 101 is provided on the end 24 and the conductive wire outlet end 25 respectively, and the wire outlet group 101 includes an installation and adjustment structure for the wire outlet. The installation and adjustment structure of the outlet bar is the installation and adjustment structure 10 of the outlet bar described in the first embodiment, and its specific structure, working principle and beneficial effects are the same as those in the first embodiment, and will not be repeated here.

[0065] Such as figure 1 As shown, the conductive wire inlet terminal 24 is composed of the outlet row group 101 installed in each installation groove 21 above the drawer base ...

Abstract

The invention provides an installation adjusting structure of an outline line row and an underframe of a drawer type circuit breaker. The installation adjusting structure of the outline line row is connected between the outline line row and a drawer base, and the distance between two outline line rows for clamping a busbar can be adjusted through the installation adjusting structure of the outline line row; and the installation adjusting structure of the outline line row comprises a bracket connected between the outline line row and the drawer base, one end of the bracket is fixedly connected with the outline line row, and the other end of the bracket is movably connected with the drawer base. The distance between two outline line rows for clamping the busbar can be adjusted through the installation adjusting structure of the outline line row to increase the actual contact area between the outline line row and the busbar, reduce the contact resistance and reduce the temperature rise.

Description

technical field [0001] The present invention relates to an installation adjustment structure and a bottom frame of a circuit breaker, in particular to an installation adjustment structure and a bottom frame of a drawer type circuit breaker applied to the outlet bar of a drawer type circuit breaker in the technical field of low-voltage electrical appliances. Background technique [0002] The universal circuit breaker is a circuit breaker commonly used in low-voltage power distribution equipment, and it is a protective electrical appliance. As a kind of universal circuit breaker, the drawer circuit breaker has been widely used and plays a leading role. The drawer type circuit breaker can quickly repair and replace the fault, and provides convenience for daily inspection and maintenance. The circuit breaker includes an incoming line terminal and an outgoing line terminal. The main circuit first transmits current to the circuit breaker through the incoming line terminal. The ci...
