Abstract: The invention relates to a device for holding in position and placing in electrical contact (5) for a connection terminal of an electrical apparatus (1), arranged to hold in position and place in electrical contact at least two electrical conductors (7a, 7b), the device (5) comprising: a first retaining element (9a) having a first engagement portion (19a) arranged to engage, in a retailing position, with a first electrical conductor (7a); a second retaining element (9b) having a second engagement portion (19b) arranged to engage, in a retaining position, with a second electrical conductor (7b); and a clamping point (23) defined at least partially in the retaining position by the first engagement portion (19a) and the second engagement portion (19b).

Abstract: 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 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.

Abstract: A method is disclosed in which the plates 2 of an electrode 1 are connected to a terminal 3 of a storage cell by clamping the plates 2 between the terminal 3 and a holding member such as a ring 6 or a washer 12 and then welding the plates 2 to the terminal 3 by transparent laser welding through the holding member. The plates 2 are preferably bent over a face of the terminal 3 before they are clamped. A tool 14 presses on an area 15 of the washer 12 to clamp the plates 2. The washer 12 and the plates 2 are then transparent laser welded to the terminal 3 along a weld line 16 around the area 15 on which the washer 12 bears. A storage cell that can be obtained by the above method is also disclosed.
