Embodiment
Now in conjunction with the accompanying drawings the utility model execution mode is further described:
The embodiment 1 of a kind of withdrawable circuit breaker electricity consumption connection of the utility model bridge type contact is extremely shown in Figure 6 as Fig. 3, include many row's contact chips unit 1, every row's contact chip unit 1 is made up of two relative contact chips 11, support 2 connects from passing between the relative contact chip 11 respectively arranges contact chip unit 1, the one side of described contact chip 11 is provided with two boss 111, these two boss 111 are symmetrical arranged with respect to support 2, and this boss 111 is cylindrical, and boss 111 is directly stretched out by the side punching out of contact chip 11.
As seen from the figure, each sheet of present embodiment 1 is to arrange example in the same way at the contact chip 11 that a side has boss 111, boss 111 roof pressures that promptly respectively have contact chip 11 have on that side that boss is set at another adjacent contact chip 11, so make the distance of being separated by between each contact chip 11 be the height of boss 111.
Those skilled in the art are noted that in present embodiment 1, obviously are arranged in contact chip 11 ＇ of side, need not to establish boss, are not to refer on all contact chips boss must be set establishing boss on the contact chip promptly also.
