Problems solved by technology

[0006] Many years of use of ammeters with bridges in the form of contact springs has shown that when opening the terminal cover at the meter's installation location, it is difficult to immediately prove that the bridge has been tampered with illegally, and in the worst case this can even lead to the failure of the entire meter.

Embodiment Construction

[0024] figure 1 A watch case 4 is shown in perspective section. The watch case 4 is designed as an electric meter case and is here only considered to be a special design of a generally known watch case. The watch case 4 comprises a case bottom 4c which is closed by a first case shield 4a and a second case shield 4b. The second housing cover 4b in this case forms a connection cover and is also referred to as such below.

[0025] In order to prevent illegal disassembly and assembly, both the first shell guard plate 4a and the wiring cover 4b have lead seals 5 or 6 respectively. The terminal cover 4b protects the terminal post 14 arranged below it and the wire 15 connected thereto. The conductors 15 are guided into the terminals 14 through connection openings 17 in the housing bottom 4c.

[0026] Except the terminal post 14 and lead wire 15 that prevent dismounting, also cover another - not shown here - additional device 18 or channel opening 21 to be protected by the additio...

Abstract

Disclosed is a housing for meters, particularly electricity meters, gas meters, heat meters, or similar, comprising a cover (4b), by means of which a number of connections (14) of the meter can be protected from unauthorized access. A first seal (6) secures the cover (4b) of the housing, which covers an additional metering device (18) that is to be protected. Said additional metering device (18) can be protected from unauthorized access by means of a second security seal (8).

Description

technical field [0001] The invention relates to a housing, in particular for electricity meters, gas meters, thermometers and the like, wherein the housing has a housing shield. Background technique [0002] It is known to use housings on eg electric / electronic devices like electricity meters, gas meters, thermometers or the like. The characteristic of the case of the watch is to prevent its illegal disassembly by means of a lead seal. For this reason, the lead seal generally connects the housing guard plate to the housing bottom, wherein the meter contacts are also covered. [0003] Especially in electricity meters, housing shields of this type are mostly composed of two parts. In this respect, the upper, first housing shield closes the measurement signal acquisition part or the electronics of the watch, while the lower, second housing shield protects the contacts to the watch. [0004] This shield part that closes the meter contacts is also called a wiring cover. With ...
