A lid structure capable of preventing a lid member from being opened due to a jet stream by using a simple structure is provided. A lid structure includes a lid member configured to cover a housing part of a housing container, and a protrusion disposed near an end of an opposing surface of the lid member, the opposing surface being located on a side of the lid member that is opposed to the housing part when the lid member covers the housing part. The protrusion is disposed in a position that is located outside the housing part when the lid member covers the housing part. The protrusion includes an inclined surface inclined from a direction perpendicular to the opposing surface toward the end of the opposing surface.

The present invention provides a cable joint protection box, which includes a buckle, at least one abutting piece, and a box body formed by two half-boxes. The two half-boxes are in rotatable pivot joint at one side of the box body via a pin, and the two half-boxes are buckled at the other side of the box body via the buckle. A dovetail groove is disposed on a front surface of the buckle. At least one through hole which penetrates through the buckle is disposed at a bottom of the dovetail groove in the buckle. A dovetail protrusion slidably buckled with the dovetail groove of the buckle is disposed on the box body. When the cable joint protection box is locked, the abutting piece is fixedly connected to the buckle, and the abutting piece penetrates through the through hole in the buckle and abuts against the box body.

A quick disconnect system for an accessory electrically coupled to a component of an amusement attraction includes a multi-part electrical enclosure including a first side, a second side opposite the first side, a first opening on the first side, and a relief pass through. The multi-part electrical enclosure is configured to: have a first electrical cable coupled to the accessory pass into the multi-part electrical enclosure via the first opening and have a second electrical cable pass into the second side of the multi-part electrical enclosure to enable the first and second cables to be coupled together within the multi-part electrical enclosure. The relief pass through is configured to provide strain relief to both the first electrical cable and the second electrical cable and to prevent disconnection of the accessory from the multi-part electrical enclosure.

A power cable termination system including: a power cable having a power cable conductor and a power cable insulation system configured to electrically insulate the power cable conductor, a termination cable having a termination cable conductor and a termination cable insulation system configured to electrically insulate the termination cable insulation system, wherein the termination cable is at least one order of magnitude shorter than the power cable, wherein the termination cable conductor has an electrical resistance which is lower than the electrical resistance of the power cable conductor and/or the termination cable insulation system has a higher insulation resistance per unit length than the power cable insulation system, a joint configured to join the power cable and the termination cable, and a cable termination device configured to terminate the termination cable.

The present disclosure provides a quick connect and disconnect cable junction box, including: a box body, insulators, copper busbars, connection wires, T-shaped cable terminals, linear adapters, and an insulation spacer. The insulators, the copper busbars, the connection wires, and the T-shaped cable terminals are positioned inside the box body. The linear adapter includes a conductive rod, an insulation layer, a quick engagement connector, and a housing. One end of each of three linear adapters is electrically connected to the T-shaped cable terminal inside the box body. The three linear adapters, three T-shaped cable terminals, three connection wires, and three copper busbars form a three-phase electrical path. During operation, the three copper busbars are correspondingly connected to three phase lines of an incoming cable of a ring main unit; and the three linear adapters are engaged with quick connectors of three bypass cable connectors via the quick engagement connectors thereof. The quick connect and disconnect cable junction box has a simple structure and low cost, and is easy to build. Using the present invention greatly reduces the installation distance of a flexible bypass cable, thus effectively addressing the difficulty of installing a flexible bypass cable to a power supply point over a long distance and improving operation efficiency of rush repair.
