The trunk line and the branch line each includes a power source line having a predetermined current capacity and a communication line having a predetermined communication capacity. The control box includes a branch line connection portion to which the branch line is connected, and a branch line control unit that distributes power from the trunk line to the branch line by controlling the branch line connection portion according to a control program. The control program can be externally changed based on the accessory connected to the branch line.

A connection device for connecting at least one electrical conductor to a stud terminal includes: a contact element which has a connecting section for attaching to a stud of the stud terminal; and a housing that has at least one plug opening configured for inserting an electrical conductor. The electrical conductor is in electrical contact with a contact section of the contact element when the electrical conductor is inserted into the at least one plug opening.

A ground shield includes a plurality of contact members configured to contact the ground contacts of a column of contacts of an electrical connector, so as to electrically common the grounds to each other.

A vehicular circuit body includes a plurality of control boxes, a trunk line that connects the plurality of control boxes to each other, and a branch line that directly or indirectly connects the control box to an accessory. The trunk line and the branch line each includes a power source line having a predetermined current capacity and a communication line having a predetermined communication capacity. Each of the plurality of control boxes includes a plurality of branch line connection portions to and from which the communication line of the branch line is attachable and detachable. Each of the plurality of branch line connection portions is provided with a lock function portion that is physically or electrically brought into a lock state in a case where the branch line is not connected thereto.

A grounding spacer is provided. The grounding spacer comprising a circular body having a top surface, a bottom surface, and a central aperture, and a plurality of radially spaced penetration features, wherein at least one of the penetration features has at least a portion thereof extending from the top surface, and wherein at least one of the penetration features has at least a portion thereof extending from the bottom surface.

A vehicular circuit body includes a trunk line that includes a power source line having a predetermined current capacity and a communication line having a predetermined communication capacity, and that is routed in a vehicle body, a branch line that is directly or indirectly connected to an accessory, and a plurality of control boxes that are disposed in a distribution manner along the trunk line, each having a control unit that distributes at least one of power from the power source line, supplied to the trunk line, and a signal from the communication line, to the branch line connected to the trunk line. The trunk line is formed of a routing material having at least one kind of conductor among a flat conductor, a round bar conductor, and a stranded wire. The communication line of the trunk line is routed so that the plurality of control boxes are connected in a ring form.

A track light structure and an earth terminal fitting are disclosed. The track light structure includes a light body having a terminal block. The terminal block has two conductive terminals for connecting a live wire and a neutral wire. The terminal block has a socket communicating with the light body for insertion of a pin extending from the underside of a base of an earth terminal fitting, so that the pin is electrically connected to the light body. The base has a connecting portion and a conductive member electrically connected to the pin. The conductive member is configured to connect an earth wire. The earth terminal fitting is selectively connected to the terminal block through the connecting portion, thereby changing the track light to a three-terminal or two-terminal configuration.

A method for grounding a hybrid or electric road vehicle which has been involved in an accident, includes making contact with a body of a road vehicle which has been involved in an accident using a first grounding tool, and subsequently grounding a second grounding tool which is connected to the first grounding tool via an electrical line and an apparatus for grounding a hybrid or electric road vehicle which has been involved in an accident. The apparatus has a grounding line, a drive-in tool for being driven into a body of the road vehicle, and a grounding stake for being planted into the ground. The drive-in tool is connected to one end of the grounding line and the grounding stake is connected to the other end of the grounding line.

A conductive component structure of wire connection terminal is manufactured at lower cost and more securely assembled with the conductive wire. 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 defines a mouth section and has an oblique wall connected with the mouth section. When the conductive wire is plugged into the case into contact with the conductive component, the restriction body guides the conductive wire and the rear end of the conductive wire is restricted and secured by the oblique wall. The conductive component improves the shortcomings of the conventional structure that the conductive wire is apt to deflect or swing due to external force to lead to unstable contact and insecurity and affect the electro-conductive efficiency.
