The second bone plate is detachably attached to the joint block of the traveling block.

A second conduction path (33) is provided to the junction block (32).

Junction block provided with connection parts avoiding the skinning of the connection wires.

The length of the connecting unit (2) can be varied telescopically, and therefore the distance between the front unit (1) and the rear unit (3) can be varied.

The selective engagement determines how far laterally outward the receptacle block (542) extends, relative to the junction block (502).

A junction block includes attaching brackets projected from the upper wall and lower wall of a block body.

The invention relates to a junction block that comprises a housing for receiving a conducting linking rod (16).

The receptacle system (100) includes a junction block (102) having an incoming female connector set (122) adapted to be engaged with a cable assembly (180) for supplying incoming power to the junction block (102).

The jointer block pieces (15) are positioned horizontally by fitting into a pair of grooves of another block piece (15) at both sides or other side to intermediate pilaster jointer (21) or corner pilaster jointer (20).

The terminal block (125) includes alignment ribs (615) and the endcap (205) includes alignment pockets (605).

Each series terminal (4) has two current bars (9) which together form a separation point, and each test plug (6) has a contact plug (10) insertable into a separation point.

The shelf lighting system further includes a driver with a power supply and a power terminal block that connects to the power track.

A road-sweeping lorry for sweeping road surfaces consists of a front unit (1) and a rear unit (3) interconnected by a connecting unit (2).

The terminal block has a main body with at least an upper surface and a lower surface.

The junction block (1) can cope with the high grade vehicle and the low grade vehicle with or without the use of the bus-bar block.
