The invention relates to a device for holding in position and placing in electrical contact () for a connection terminal of an electrical apparatus (), arranged to hold in position and place in electrical contact at least two electrical conductors (), the device () comprising: a first retaining element () having a first engagement portion () arranged to engage, in a retailing position, with a first electrical conductor (); a second retaining element () having a second engagement portion () arranged to engage, in a retaining position, with a second electrical conductor (); and a clamping point () defined at least partially in the retaining position by the first engagement portion () and the second engagement portion ().

Device for holding and bringing into electrical contact conductors

There is described a test block intended to be implanted in the circuit connecting an apparatus to be tested such as an electricity meter or a protective relay and a power source supplying the apparatus to be tested such as an intensity sensor and/or a voltage sensor, the test block comprising a base including a plurality of inner electric circuits capable of allowing the transmission of information from the power source to the apparatus to be tested and a protective cover intended to be removably assembled with the base in order to form a closed enclosure in which the inner electric circuits are housed. The base and the protective cover are configured such that the removal of the protective cover gives access to a receiving site delimited by the base and capable of receiving, by plugging, a test plug independent of the test block and electrically linked to a test equipment, in particular a voltmeter and/or an ammeter and/or a dummy current source. The base and the protective cover comprise electrically conductive elements linked to each other and configured so as to ensure a continuity and magnetic shielding closure such that the enclosure delimited by the base and the protective cover is a Faraday cage protecting the inner electric circuits relative to the magnetic fields external to the enclosure delimited by the base and the protective cover.

The invention relates to a test block intended to be implanted in the circuit connecting an apparatus to be tested such as an electricity meter or a protective relay and a power source supplying the apparatus to be tested such as an intensity sensor and/or a voltage sensor. The test block comprises a base including a plurality of inner electric circuits capable of allowing the transmission of information from the power source to the apparatus to be tested and a protective cover intended to be assembled in a dismountable manner with the base in order to form a closed enclosure in which the inner electric circuits are housed. The base and the protective cover are configured such that the removal of the protective cover gives access to a receiving site delimited by the base and capable of receiving by plugging a test plug independent of the test block and electrically linked to a test equipment, in particular a voltmeter and/or an ammeter and/or a dummy current source. A test appliance is also described.
