The invention concerns a rack module for forming a support column, such as a rack, by stacking at least two rack modules, the rack module having at least one site for receiving a device for administering a medical product, this site comprising at least one plug for electric current supply to the administering device and for data transfer. It is also provided with an inlet connector and an outlet connector for connecting two successive modules to each other, power lines and data transfer lines connecting the inlet connector with the plug of the sites on the one hand side and with the outlet connector on the other hand side. In order to improve the connection between the rack modules in order to make its use easier, it is suggested according to the invention that the inlet connector or the outlet connector is movable between a stocking position and a connected position, the movable connector being called mobile connector and the other connector being called second connector, wherein, when a second module is placed over or under the module, the mobile connector in the connected position is in connection with the second connector of a second module placed over or under the module. This allows to stock in a safe position one of the connectors so that during the stocking and the handling of the module there is no risk for it to be damaged.

The insulative body includes a first member that allows transmission laser light having a predetermined wavelength, a second member that absorbs the laser light, and a welding portion. The first member and the second member are welded to each other at least at a part of a contact portion between the first member and the second member in the welding portion. The main body includes a contact point exposed from the insulative body.

Device for securing an object on a rail, having an elongated base body which may be placed transversely on the rail and which at one end comprises an integrated actuating element which, when actuated by a user, moves opposing latching hooks which are integrated in the actuating element and are suitable for engaging behind the rail, in opposite directions.

A measuring and/or control system (1), to control for example a machine tool, comprises at least a first and a second unit, each comprising a casing with a front wall, electronic circuits and at least one socket. The system further comprises a bridge connector (11) having a first multipolar connector (11A) and a second multipolar connector (11B), each of which can be coupled to one of the sockets in order to electrically connect the first and the second unit. In each of the first unit and second unit, the socket is positioned on the respective front wall and comprises planar electrical contacts. The first and the second multipolar connectors of the bridge connector are directed in the same direction so as to face the front wall of the first unit and the second unit and each comprise retractable contacts. The bridge connector comprises fastening elements for fastening the bridge connector to the front wall of the first unit and of the second unit.

The power distributor for vehicles according to the present disclosure includes at least the following components: an electronic attachment and a central distributor module with a printed circuit board for electrical components, a feed-in busbar to connect the printed circuit board to a feed-in terminal, and a cable directly connected to the power distributor.
