The present invention relates to a system and method of locking housings that have two different stages, one being generally used for transportation after an initial production stage, and the other being intended for final use of the product, preferably used on electric compressor inverters. One embodiment of the invention presents a system for locking housings that have a base (1), a cover (2) and internal elements (4) arranged in an internal portion of the base (1), the cover (2) being locked to the base (1) by means of at least one fastening element (3), the fastening element (3) having first reversible locking stage (a) and second irreversible locking stage (b), the locking system being configured so that the reversible locking stage (a) will enable the opening of the housing for access to the internal elements (4), and the irreversible locking stage (b) will effect tamper-proof closure of the housing. The invention also presents a housing fastening element (3), a protection housing for an electric compressor inverter, an electric compressor and an electric compressor inverter that use the housing with the fastening element (3) presented. Finally, a method is provided for locking housing and comprises the steps of:
(e) mounting a part of the internal elements (4) onto the base (1);
(f) locking the cover (2) onto the base (1) by means of first reversible locking stage (a) of the fastening element (3), configured to keep a vertical distance between the base (1) and the cover (2) and to enable the opening of the housing for access to the internal elements (4);
(g) reversing the locking of the housing and mounting the remaining internal elements (4) onto the base (1);
(h) locking the cover (2) onto the base (1) by means of second irreversible locking stage (b) of the fastening element (3), configured to effect tamper-proof closure of the housing and protect the internal elements (4) mounted on the base (1). |
