Definitions

  • the present invention generally relates to electrical outlets for industrial or service sector use, and particularly relates to an interlocked electrical outlet.
  • Interlocked electrical outlets are electrical power distribution devices which can be mounted on a wall or installed on special support panels.
  • An interlocked electrical outlet generally comprises a housing provided with connection means for wall assembly, for example, a plurality of holes adapted to receive securing screws.
  • the housing accommodates an electrical switch, an electrical outlet adapted to receive a corresponding electrical plug (for example, in accordance with the European standard EN 60309 cafterrning industrial electrical connectors), and electrically connected to the switch so as to be able to allow and interrupt the power supply, as well as an interlock mechanism interacting with switch and electrical outlet so that the electrical outlet can receive and release the plug only after the switch has been turned off and the switch can be turned on only after the plug has been plugged into the electrical outlet.
  • an electrical switch for example, in accordance with the European standard EN 60309 cafterrning industrial electrical connectors
  • a protecting device can be provided, for example, a fuse assembly which is electrically connected between switch and electrical outlet.
  • the object of the present invention is thus to provide an interlocked electrical outlet having such characteristics as to eliminate the risk of electrical shock caused by any inadvertent access to the fuse-carrier assembly, when the fuse-carrier assembly is energized.
  • the interlocked electrical outlet comprises:
  • the fuse-carrier locking portions may comprise at least one plug which is suitable to engage, when the interlock mechanism and switch are in the power connection configuration, a corresponding seat or hole being formed in a fuse drawer of the fuse-carrier device to prevent the fuse-drawer from being opened. Due to the fuse-carrier locking portions, when the switch is activated, both an individual fuse and the seat thereof that is formed by the fuse-carrier device cannot be accessed, thereby completely eliminating the risk of electric shock that may arise from any inadvertent contact with conductive parts of the fuse-carrier assembly.
  • the dependant claims relate to advantageous embodiments.
  • Fig. 1 is an exploded view of an interlocked electrical outlet according to an embodiment
  • Fig. 2 is a perspective view of a fuse-carrier assembly of the interlocked electrical outlet in Fig. 1 with a fuse-carrier locking portion being in a disengaged configuration
  • Fig. 3 is a perspective view of the fuse-carrier assembly and fuse-carrier locking portion in Fig. 2 in the engaged configuration
  • Fig. 4 is a perspective view of a front shell of the interlocked outlet when assembled (the wiring has been omitted for clarity purposes),
  • Fig. 5 is a front perspective view of the interlocked outlet according to an embodiment (a rear shell has been omitted),
  • Fig. 6 is a perspective view of an interlock mechanism according to a further embodiment with a closed-section latch with two side bars.
  • an interlocked electrical outlet is generally designated with the reference numeral 1.
  • the interlocked outlet 1 comprises a housing 2, inside which an electrical outlet 3 is accommodated which is adapted to receive a corresponding electrical plug (not shown), a switch 4 electrically connected to the electrical outlet 3 so as to be able to thereby turn on and off the power supply, and an interlock mechanism 5 interacting with switch 4 and electrical outlet 3, so that the electrical outlet 3 can receive and release the plug only after the switch has been turned off, and the switch 4 can be turned on only after the plug has been plugged in the electrical outlet 3.
  • the switch 4, particularly a shaft 30 thereof or actuating handle 31 of switch 4, comprise a dragging portion 32, for example, an eccentric pin actuating an interlock mechanism 5, which will be described herein below.
  • the interlocked outlet 1 comprises a fuse-carrier assembly 33 which is electrically connected between the switch 4 and outlet 3.
  • the fuse-carrier assembly 33 can comprise a plurality of individual fuse-carrier devices 34, each adapted to hold a fuse, and provided with contact terminals in order to allow the fuse electrical connection in the power supply lines between switch 4 and electrical outlet 3.
  • the interlock mechanism 5 comprises a latch 48 movably arranged, preferably translatable, in a latch seat 49 formed in the housing 2.
  • the latch 48 comprises an actuating seat 50 connected to the switch 4 dragging portion 32 so that a switching of the switch 4 between a connection position and a power supply interruption position involves a corresponding movement of the latch 48 between a connection position and a power interruption position.
  • the latch 48 comprises a plug locking portion 51 arranged at an outlet seat 21 of housing 2 and configured so that:
  • the plug locking portion 51 results constraint by the outlet 3 or outlet seat 21 in the power interruption position, thus preventing a latch 48 movement from the power interruption position to the electrical connection position and
  • the plug locking portion 51 releases the outlet 3 or outlet seat 21, thus allowing the plug plug-in and withdrawal and
  • the plug locking portion 51 directly or indirectly engages the plug, thus preventing the withdrawal of the latter from the outlet 3.
  • the latch 48 or, generally, the interlock mechanism 5 further comprises a door locking portion 52 interacting with a corresponding hook 53 of a fuse-carrier door 54 so that, when the latch 48 is in the electrical connection position, the door locking portion 52 fastens the fuse-carrier door 54 in the closed position, thus preventing the latter from being opened, thereby preventing access to the fuse-carrier devices and, when the latch 48 is in the power interruption position, the door locking portion 52 releases the fuse-carrier door 54, thus allowing the latter to be opened.
  • the latch 48 or, generally, the interlock mechanism 5 can further comprise one or more fuse-carrier locking portions 55 interacting with the individual fuse-carrier devices 34 so that, when the latch 48 is arranged in the electrical connection position, the fuse-carrier locking portion 55 fastens the fuse-carrier device 34 to a closed configuration, thus preventing access to the individual fuse and, only when the latch 48 is in the power interruption position, the fuse-carrier locking portion 55 releases the fuse-carrier device 34, thus allowing the opening of the latter.
  • the fuse-carrier locking portions 55 comprise at least one pin adapted to engage, when the latch 48 is in an electrical connection position, a corresponding seat or hole 56 formed in a fuse drawer 57 (supporting the fuse) of the fuse-carrier device 34 in order to prevent the fuse drawer 57 from being opened.
  • the fuse-carrier assembly comprises a plurality of fuse-carrier devices 34, each being provided with its own fuse drawer 57 with a seat or hole 56 suitable to receive one or a series of plugs 55, respectively, which is configured in a "comb-like shape" such as to prevent the fuse drawer 34 from being opened (withdrawn).
  • the latch 48 is hold in place by a preferably screwless shape connection in an interspace between switch 4 and switch seat 25 of the housing 2.
  • Fig. 4 further illustrates a pushing device 58 secured to the housing 2 by means of screws or, alternatively, by a snap connection or by press-fit, and provided with an elastic arm 59 acting with an elastic pre-load on a portion (for example, the hook 53) of the fuse-carrier door 54 in order to make the opening thereof easier (when the switch and interlock mechanism are in the electrical interruption position).
  • a pushing device 58 secured to the housing 2 by means of screws or, alternatively, by a snap connection or by press-fit, and provided with an elastic arm 59 acting with an elastic pre-load on a portion (for example, the hook 53) of the fuse-carrier door 54 in order to make the opening thereof easier (when the switch and interlock mechanism are in the electrical interruption position).
  • all the electrical components electrical outlet, switch, interlock mechanism, and fuse-carrier assembly are directly connected to a housing 2 front shell 60, which can, in turn, be connected by means of screws 61 to a rear shell or other support, such as on a wall, in order to complete assembly and installation.
  • the interlock mechanism may comprise a rack-, geared-, articulated quadrilateral-, spring-, cam-, belt- mechanism, or similar mechanical devices, which are suitable to transmit and transform the switch motion into a lock/release motion of the locking portions.
  • the interlocked electrical outlet according to the present invention is particularly safe in that it eliminates the risk of electrical shocks which may be due to the operator coming in contact with the outlet and fuse-carrier assembly.
  • the interlock mechanism results to be substantially planar and plate-like and, therefore, particularly suitable for assembly in narrow space conditions.
