BS ISO 17612 pdf download Tractors and machinery for agriculture and forestry — Auxiliary-power- transmission connector for the operator station
1 Scope
This International Standard specifies the essential interface dimensions of a connector and its plug for the transmission of 12 V electrical power within the enclosed operator station of agricultural tractors and machinery. The device is intended to be used as a non-environmentally sealed, convenient source for power auxiliary devices, providing a means for the operator to obtain electrical power without altering the tractor/machine electrical wiring harness. The maximum current capacity of the specified device is 30 A: it is not applicable to any other voltage system (6 V or 24 V).

4 Requirements
4.1 Dimensional requirements
4.1.1 Power strip socket
The connector shall consist of a base containing one or more sockets.
Each socket shall be covered with a lid, which shall be spring-loaded to close or have a detent to hold it in the closed position. The lid shall have symbols defining the contact positions and their respective use.
A typical example is shown in Figure 1, for reference purposes only.
The socket and pin spacing dimensions shall be in accordance with Figure 2.
Female contacts shall be of at least a tin-plated material designed to mate with the male contacts specified in Figure 3.
4.1.2 Power strip plug
Critical outside dimensions of the power strip plug shall be in accordance with Figure 4 to allow typical mating with the power strip socket.
