The conductive members, for example, may include regions, adjacent tie bar locations, that compensate for portions of the tie bar that are not fully removed.

All have, on one side, a series of contact pins engaging into a connection bar (13) integral with a master card (14).

If combining several Vario appliances of the 400 series, a connection strip VA 420 must be placed between the appliances.

The conductive members, for example, may include regions, adjacent tie bar locations, that compensate for portions of the tie bar that are not fully removed.

The invention relates to a junction block that comprises a housing for receiving a conducting linking rod (16).

Electrical communication is established with the components via a header assembly that includes plug receptacles.

All have, on one side, a series of contact pins engaging into a connection bar (13) integral with a master card (14).

The only P.N. junction is between the bar and the E electrode, corresponding to the transmitter.

These contacts are of the purely ohmic type, that is to say between them and the silicon bar, there is NO JUNCTION.

In order to improve the compatibility, the terminal box (1) is placed in front of the appliance and contacting takes place by means of a plug connector (5).

If combining several Vario appliances of the 400 series, a connection strip VA 420 must be placed between the appliances.

The joining assembly includes an internal joining tool and an external joining tool.

A bottom bar (22) is attached to the top bar (20) and a grasping member (28) is rotatably attached to the bottom bar (22).

These contacts are of the purely ohmic type, that is to say between them and the silicon bar, there is NO JUNCTION.

The joining method also includes a temporary joining step conducted before the final joining step.
