Abstract

In un dispositivo di piombatura per apparecchi, specialmente per contatori di elettricità, un perno (1) formato da un gambo (6) e da una testa (5), chiude una custodia (4) formata da una prima parte (2) della custodia e da una seconda parte (3) della custodia. Lobi (8) ricavati per stampaggio sul gambo (6) impediscono una rotazione del perno (1) ed un meccanismo a scatto formato da denti (9) impedisce che il perno (1) venga tirato indietro. Per aprire la custodia (4) la testa (5) del perno (1) deve essere staccata dal gambo (6). Una apertura della custodia (4) da parte di persone non autorizzate è pertanto identificabile. Il perno (1) può essere costruito in qualità di pezzo di materiale sintetico stampato ad iniezione. Il dispositivo di piombatura diventa pertanto economico.(Figura 1)In a sealing device for appliances, especially for electricity meters, a pin (1) formed by a stem (6) and a head (5) closes a housing (4) formed by a first part (2) of the housing and a second part (3) of the housing. Lobes (8) obtained by molding on the shank (6) prevent rotation of the pin (1) and a click mechanism formed by teeth (9) prevents the pin (1) from being pulled back. To open the case (4) the head (5) of the pin (1) must be detached from the stem (6). An opening of the housing (4) by unauthorized persons is therefore identifiable. The pin (1) can be constructed as a piece of injection-molded synthetic material. The sealing device therefore becomes inexpensive. (Figure 1)
