Tankage 21 can coordinate outlet row group and the bridge-type contact of connection corresponding with the outlet row in the outlet row group to form conductive leading-out terminal
25, the bridge-type contact is the arrangements of electric connection that outlet row 1 turns on open frame circuit breaker inner conductive system；In the utility model
In, at least one outlet row group can be installed in each mounting groove 21.Two outlets are comprised at least in outlet row group described here
Row 1, for connecting one or more busbars 3, outlet row 1 of the present utility model T-shaped outlet row different from the past, it is U-shaped go out
Line is arranged or the structure of L-type outlet row, and the outlet row 1 is a horizontal copper coin, and two outlet rows 1 be arrangeding in parallel are used to clamp one
Busbar 3.
Wherein, in the embodiment shown in fig. 1, in each mounting groove 21 on drawer pedestal 2, each outlet row 1 can be horizontal
It is arranged at intervals；Or in the embodiment shown in fig. 6, in each mounting groove 21 on drawer pedestal 2, each outlet row 1 can be vertical
It is arranged at intervals；Or in other embodiments, in each mounting groove 21 on drawer pedestal 2, each outlet row 1 can be according to mother
The arbitrarily selection of the putting position of row 3 is connected on drawer pedestal 2 in a manner of being horizontally spaced about or vertical spacing is set, herein
It is not limited, for example, in the embodiment shown in fig. 11, each outlet row 1 in each mounting groove 21 above drawer pedestal 2
It is horizontally spaced about, the vertical spacing of each outlet row 1 in each mounting groove 21 of the lower section of drawer pedestal 2 is set.
In the utility model, as shown in figure 4, the installation and adjustment structure 10 of the outlet row is attached to two outlet rows 1
In one of on, that is, one of outlet row 1 in two outlet rows 1 of sandwiched busbar 3 is (underlying in Fig. 4
Outlet row 1) the installation and adjustment structure 10 of an outlet row is connected between drawer pedestal 2；Or as shown in figure 8, at two
The installation and adjustment knot of the outlet row can be connected with outlet row 1 (two outlet rows 1 being disposed adjacent for being located at left side in Fig. 8)
Structure 10, this is not restricted.
In addition, in embodiment as shown in Figure 8, three outlet rows can be arranged side by side in the mounting groove 21 of drawer pedestal 2
1, wherein two outlet rows 1 on the left of Fig. 8 are removable by the installation and adjustment structure 10 and drawer pedestal 2 of outlet row respectively
Ground is connected, and an outlet row 1 on the right side of Fig. 8 is fixedly linked by the fasteners such as screw and drawer pedestal 2.Namely
Say, two on the left of Fig. 8 outlet row 1 can carry out adjustment of displacement with respect to drawer pedestal 2, and be located at an outlet row 1 on the right side of Fig. 8
It can not be moved with respect to drawer pedestal 2.Certainly, in other embodiments, can be set side by side in the mounting groove 21 of drawer pedestal 2
Put four, five or more outlet rows 1, the quantity of the outlet row 1 can be even number or Odd number,
This is not limited.
The utility model is by the way that outlet row 1 to be designed as to the structure of horizontal copper coin so that outlet row 1 and drawer pedestal 2
Connect it is more convenient and flexible, and each mounting groove 21 in set outlet row 1 quantity can arbitrarily adjust, take full advantage of drawer base
