Embodiment Construction

[0021] FIG. 1 shows an electrical or electronic device 1 by way of example of a watt-hour meter. The device 1 comprises a housing bottom 2 which is closed with a housing top 3 . The instrument 1 has a first cover 4 and a second cover 8 on the front side. Furthermore, there is a calibration seal 6 , which prevents unauthorized access to the interior of the device 1 . Another lead seal 7 protects the cover plate 8 on the upper part 3 of the housing. Said further seal 7 can be opened for servicing purposes without the instrument 1 losing its calibration validity (seal 6). The third seal 5 prevents the first cover 4 from being opened; here it is also a seal that is opened for maintenance purposes - either when required or periodically. The third seal 5 is shown opposite to the seals 6 and 7 without a lead block. Only seals 6 and 7 have sealing pins as sealing blocks in the figures.

[0022] FIG. 2 shows the cover 4 in the open position, wherein it can be seen that the lead se...

Description

technical field [0001] The invention relates to the field of electrical and / or electronic instruments; the invention relates to functional units of such instruments. Background technique [0002] Conventional instruments have, for example, an instrument cover that can be pivoted about an axis of rotation outside the secured instrument part. On the inner wall of the reversible instrument cover, a functional unit for installing a battery can be releasably fixed near the rotation axis of the instrument cover. When the instrument cover is opened, the means for installing the battery are accessible in such a way that the battery can be replaced quickly. The battery contact connection leads out of the device and leads to the secured instrument part in such a way that it can be quickly exchanged together with the device. This arrangement allows simple and quick battery replacement without dismantling the instrument, without disconnecting the power supply and without damaging the ...
