    In a charging set for the regenerative recharging of dry batteries that consists principally of a hollow insulating casing (1) provided with a inner hole (13) for removably receiving standarized types of dry batteries, with mains contact pins (21, 22) for applying the charger set to nearly all standardized types of mains sockets, and of a charger rectifier circuitry, the improvement according to the invention is characterized in the charging rectifier comprising passive electric circuit elements only and no charger transformer, and simultaneously, the casing (1) being designed and shaped so as to be absolutely shock-proof by excluding access to any naked area of the inserted dry battery and all naked live contactors (30) and component parts of the charging rectifier while the mains contact (21, 22) and thus, the charging set are being applied to the mains for normal operation.

    The invention relates to electrical engineering, in particular to charging units for the recovery recharging of dry batteries.
    The purpose of the invention is to ensure the safety of use of the unit by eliminating electric shock during operation.
    FIG. 1 - charge unit, view
    on the side of FIG. 2 is the same, front view in FIG. 3 shows section A-A in FIG. in fig. 4 - charge unit, axonometric variant; in fig. 5 - the same, in the position of free access to the internal free cavity for insertion of the battery, axonometric. The charging unit comprises a housing 1 made of an insulating material, preferably thermoplastic, by injection molding. The casing includes an internal cavity 2 (Fig. 3), access to which is provided through the opening 3 for easy insertion (and removal) of one 9-volt dry type 6F22 battery for its regenerative recharge. In the bottom wall of the inner pole 2 there is a bare electrical installation.

    The charging unit is designed for simultaneous recovery contacts of 4a and 4c in the appropriate: for-30 charging of four cylindrical stations, which combine with the contact terminals of the battery (not shown), which is reparable. The charging unit is connected to the mains via mains pins 5 and 6 (Fig. 2), which are easily plugged into a standard standard power outlet. A simple rectifier circuit consisting of two ohmic resistances, each of which is directly connected to one of the network pins 5 and 6, and two diodes connected in series with the resistances, is installed inside the casing 1.
    The casing 1 is equipped with a plug 7, designed for power outlets of any standard types and for earthed sockets equipped with insulated interme35

    Dart-type dry batteries -Kb. The plug 7 with the network contacts 5 and 6 is also provided with an insulated intermediate rod 8 of the corresponding cross-section and a protrusion for inclusion in most types of standard power sockets. The casing 1 of the charging unit is provided with a covering element 9 having the possibility of linear sliding between the closed second position (Fig. 4) and the open first position (Fig. 5). In the open first position of the covering β-element 9, the internal cavity 2 of the case 1 is freely accessible for insertion, removal and replacement of dry batteries to be recharged or recharged. With the open First position, bare metal contacts 4 ", 4b, 4c can be touched, however absolute accident prevention is ensured due to the impossibility of switching the charging unit into the network and, thus, being under the voltage of bare metal sections, which is provided by the covering element 9 its first position (Fig. 5), the charging unit can be included in the network
    a joint rod 8 of the corresponding cross section with a protrusion. The network contact pins 5 and 6 are held at a predetermined standard spacing among themselves by means of a plug 7 forming one whole with the casing 1,
    In addition, the casing 1 is provided with a cutting element 9 inclined movably between the open first position and closed with the second position
    by turning on the axis 10 installed in the casing 1.
    With the open first position of the covering member 9 (FIG. 3), the dry battery can be easily inserted or removed from the inner cavity 2 of the housing 1 through the access opening 3. When the covering element 9 is in its first position, the network contact pins 5 and 6 of the plug 7 cannot be included in the network, since the said covering element eliminates this possibility. The charger can be switched on to the network by itself only if the covering element 9 is turned to its second, closed position (Fig. 1). However, in this position, access to any possibly energized sections of the inserted battery and components of the charging rectifier inside housing 1 is completely excluded, with the result that the charging unit is completely safe in terms of electric shock.
    The charging unit is designed for simultaneous recharging of four cylindrical stans

    only in case the piercing element 9 is slid into its second Closed position, preventing access to the inside of the insulating casing 1.
    Thus, this variant of the charge aggregate is also completely safe in the sense of an electric shock.
