The fuse element is connected in series between the cable connection portion and the first connecting element. The second cable assembly is electrically connected to the cable connecting portion.

An irrigation control wiring system includes an irrigation control valve box embedded into an earthen surface and defines an interior cavity below the earthen surface. The system further includes a removable cover adapted for installation over a top opening of the valve box and a back plate attached to an interior surface of the removable cover. The back plate includes multiple wire connectors. A bundle of wires passes into the interior cavity through a first opening in the valve box with each wire having a proximal end connected to at least one of the connectors and a distal end connected to a microcontroller remotely disposed from the valve box. Finally, the system includes individual wires, each coupled to a different one of the connectors at a proximal end and at a distal end to a respective sprinkler remotely disposed from the valve box within a sprinkler zone.

A bent portion of electric wires is protected at a high versatility by a protective member having a simple shape. A wire end of a wire harness 11 is protected. The wire harness 11 includes a wire bundle 13 and a connector 14 connected therewith. The wire bundle 13 includes the wire end, and the wire end includes a bent portion 13a and faces the connector 14. First, a sheet member 15a is folded perpendicularly to a wire lead-out surface 14a of the connector 14, thereby forming, concurrently, counter sides 31 facing the wire lead-out surface 14a, side surface covering portions, and a tip end protection portion 33. Next, the side surface covering portions are folded along a top protection portion formation portion 44, thereby forming, concurrently, side surface protection portions 32, a top protection portion 34 and an extending portion 35. Next, a wire end protection portion 15 is secured, with a pressure-sensitive adhesive tape or the like, to a wire bundle 13 portion while the relative position of the counter sides 31 with respect to the wire lead-out surface 14a is maintained. The wire end protection portion 15 is secured only to the wire bundle 13 portion, but is not secured to the connector 14.

A conductive component structure of conductive wire connection device is more securely assembled with the conductive wire to enhance the electro-conduction performance. The conductive component includes a main body in the form of a plate body and a restriction body connected on the main body. The restriction body has a base section, a first arm and a second arm connected with the base section and free sections connected with the first and second arms, which together provide elastic holding action force for the restriction body. When the conductive wire is plugged into the case into contact with the conductive component, the rear end of the conductive wire is at least securely pressed between the first and second arms of the restriction body without deflecting or swinging due to external force.

An insulating cover includes a cover main body and a pair of supporters. The cover main body is open in one direction along a radial direction of a tubular portion of a crimp terminal. The cover main body is configured to be disposed outside a terminal base. The cover main body is configured not to cover at least a region of a plate portion of the crimp terminal. The region is configured to face an electrical connection portion of the terminal base. The cover main body is configured to cover the tubular portion. The pair of supporters is configured to face at least one of an electrical wire and the tubular portion on a side opposite to the cover main body.

To provide a stack-type wire mount wafer connector and a connector assembly that can reduce the number of components and the size, and can enhance operability of insertion and removal. A latch portion 25 that is integrally formed with a wafer 40 and extends along a second side surface 46a of the wafer 40, at least one protrusion 47b extending outward along a Z-axis direction of the wafer 40 from a first base portion 47 of the wafer, and at least one opening portion into which the protrusion 47b of another stack-type wire mount wafer connector 20 is to be inserted are included. When the protrusion 47b of another stack-type wire mount wafer connector 20 is inserted into the opening portion of the stack-type wire mount wafer connector 20, shifting between the stack-type wire mount wafer connector 20 and another stack-type wire mount wafer connector 20 in a fitting direction (X-axis direction) of a fitting connector is prevented.

An electrical cover for a terminal block of a device is provided that protects the terminal block from risks associated with stray wires. The electrical cover retains desired wiring in a connection space of the terminal block while also guarding against other stray wiring from entering the connection space.

A smart power device includes a control module having a communication circuit and a switching circuit. A power transfer unit is electrically connected to the switching circuit.
