The present invention discloses an anti-electric shock mechanism for a power converter comprising a protective tube provided in the power converter and further comprising a locking guide block provided in the power converter, and a protective holder for mounting the protective tube, wherein a locking groove is formed on the protective holder, and a locking part inserted into the locking groove is provided on the locking guide block. The anti-electric shock mechanism for the power converter provided by the present invention can prevent the risk of electric leakage and electric shock when the power converter is used, whether the protective tube has not been pulled out, is partially pulled out or has been completely pulled out, so as to improve the safety of the power converter.

A cover includes a top wall, a first side wall, a second side wall facing the first side wall, and a lock releasing portion. The first side wall includes a locking portion engageable with a locked portion of a covered body. The second side wall includes an opposed locking portion engageable with an opposed locked portion of the covered body. The lock releasing portion includes: a release operation portion inclined and projecting from the top wall in a cover mounting direction; and a connecting portion connecting the release operation portion with the first side wall around the locking portion or the release operation portion with the locking portion.

A fuse holder for holding a fuse is provided. The fuse holder includes a body, a line side connector supported by the body, and a load side connector supported by the body. The fuse holder also includes a fuse carrier supported by the body. The fuse carrier is adapted for holding the fuse and the fuse carrier is adapted to be removed from the fuse holder. The fuse carrier defines a longitudinal axis thereof. The fuse carrier is separable from the body in a direction along the longitudinal axis of the fuse carrier.

A fuse holder for holding a fuse is provided that includes a body, a line side connector supported by the body, and a load side connector supported by the body. The fuse holder also includes a toggle switch supported by the body and capable of toggled engagement in a first position that provides electrical connection. The switch is also capable of toggled engagement in a second position that provides electrical isolation between the line side connector and the load side connector. The fuse holder also includes a fuse carrier. The fuse carrier is supported by the body and adapted for holding the fuse and the fuse carrier is adapted to be removed from the fuse holder. The fuse holder includes a blocking device blocking the toggled engagement of the switch from the second position to the first position when the fuse carrier is not within the fuse holder.

A charging device for electric vehicles or plug-in hybrids has a housing. At least one printed circuit board with fuses thereon is arranged on the printed circuit board. The printed circuit board, together with the fuses, is arranged in the interior of the housing and is connected to the housing in a force-fitting and/or interlocking manner by at least one fastening element (2). A covering element (1) covers the printed circuit board and the fastening element (2) at least in sections, and insertion or removal of the fuses onto or from the printed circuit board can be carried out only by removing the printed circuit board from the interior of the housing. The covering element (1) has to be damaged at least in sections to remove the printed circuit board.

A fusible disconnect switch includes a switch housing, and a first fuse contact member and a second fuse contact member coupled to the switch housing, each of the first fuse contact member and the second fuse contact member configured to engage and complete an electrical connection through an overcurrent protection fuse. The fusible disconnect switch further includes a switch contact including a parallel contact configuration. An interlock is operatively coupled to the first fuse contact member and a switch that operates the switch contact, the interlock configured to inhibit movement of the switch from the OFF position to the ON position when the first fuse contact member is unsecured to the switch housing, and inhibit movement of the first fuse contact member relative to the switch housing when the switch is in the ON position.

In one embodiment, a fuse cutout cover has an integral roof portion. The roof portion covers the energized top of a fuse in a first type of cutout. An attachable roof extension covers the energized top of a fuse in a larger second type of cutout. By having the optional roof extension feature, the same cover may be used with two types of cutouts. The roof extension is connected using a cruxiform connector on the bottom surface of the roof portion that tightly fits into a hole in the roof extension. To prevent an air gap between the cruxiform connector and the hole in the roof extension, the bottom of the hole is sealed. This prevents flashovers through the air gap. As a result, electrical insulation between wildlife and the energized cutout is increased.

The invention refers to a fuse switch module (1) that comprises a casing (2) having an aperture (3) and a cover (4) for closing and opening the aperture (3), and a rotatable fuse cartridge (11) for receiving a fuse (8). The fuse cartridge (11) is rotatable between a switch module closed position in which a fuse (8) is connected with fixed contacts (5,6) to enable current circulation, and a switch module open position in which current circulation through the fixed contacts (5,6) is impeded. The cover (4) and the fuse cartridge (11) are engaged when the cover (4) is closing the aperture (3) and when the fuse cartridge (11) is in the switch closed position, thus, the cover (4) is locked by the fuse cartridge (11) and opening of the cover (4) is impeded while current is circulating through the switch module.
