A wiring harness system and installation method is provided for customizing a truck chassis to a provide quick and easy addition and repair of electrical features on a completed heavy-duty truck body. The system and method add the existing wires of the chassis, without the need for cutting or disconnecting anything on the chassis. A primary harness connects to the body builder plug and upfitter plug of the chassis and extends along the frame rails to the rear of the truck. One or more extension harnesses can be plugged into the connectors on the primary harness, with various electrical features of the truck body being plugged into the extension harnesses or the primary harness.

An electrical plug connector includes a metallic shell, a first insulated housing in the metallic shell, and a second insulated housing in the metallic shell. The first tail portions of the first terminals are divided into a first tail group and a second tail group. The second insulated housing and the first insulated housing are combined with each other. Each of the second terminals includes a second tail portion between the first tail group and the second tail group. The second tail portions and the first tail portions are aligned at a same horizontal height.

The invention relates to an electric switch for electric appliances. The electric switch include a switch housing, an actuating element, and a plug socket. The actuating element is configured to switch a contact system accommodated in the switch housing by movement between a switch-off position and a switch-on position. The plug socket is non-detachably connected to the switch housing. Electrical connections of the contact system are held in the plug socket such that ends of the electrical connections are in predetermined positions.

A system including an electrical header connector assembly is provided. The electrical header connector assembly includes an insulated body with a mating body portion and a strain relief portion, a first self-shorting contact and a second self-shorting contact. Each self-shorting contact includes a contact tail with a wire receiving recess and a contact blade extending opposite and substantially parallel to the contact tail. Each self-shorting contact further includes a shorting beam extending opposite the contact tail. The shorting beam includes a curved portion extending away from the contact blade and a bent tip portion extending toward the contact blade. The shorting beam of the first self-shorting contact is configured to touch the shorting beam of the second self-shorting contact when the electrical header is in a neutral position.

An electric terminal includes a contact portion that includes a contact box. A first contact arm extends from the contact box and is adapted to engage a corresponding terminal. The electric terminal also includes a spring portion with a first spring box that is located around a portion of the contact box. The spring portion also includes a second spring box that is located adjacent to the first spring box. The first spring box includes a first spring arm that engages the first contact arm. The second spring box includes a first guard that engages the first spring arm.

Disclosed herein is an electrical connector, comprising a plug and a receptacle. The plug comprises first electrical contacts electrically isolated from each other and arranged into a first outer contact annulus and a first inner contact annulus concentric with and radially spaced apart from each other. The receptacle comprises second electrical contacts electrically isolated from each other and arranged into a second outer contact annulus and a second inner contact annulus concentric with and radially spaced apart from each other. The plug is selectively connectable with the receptacle. When the plug is selectively connected with the receptacle, each of the first electrical contacts of the first outer contact annulus is in physical contact with a corresponding one of the second electrical contacts of the second outer contact annulus and each of the first electrical contacts of the first inner contact annulus is in physical contact with a corresponding one of the second electrical contacts of the second inner contact annulus.

A moving plate moves from a protection position for protecting a tip part of a male tab to a connection position in a receptacle according to a connecting operation of a female housing. A male housing includes a male housing lock, and the female housing includes a female housing lock. The moving plate includes a plate male lock for locking the male housing lock at the protection position to restrict a movement to the connection position, and a plate female lock for locking the female housing-side locking portion to restrict separation of the female housing when locking of the male housing lock and the plate male lock is maintained.

In a connector, a spacer includes lock parts and regulation parts. Each of the lock parts locks a first terminal in a first terminal receiving slot after the first terminal is inserted into a proper position in the first terminal receiving slot. Each of the regulation parts regulates deformation of a second lance toward a release position when the second lance is located in a lock position in which the second lance locks a second terminal in a second terminal receiving slot after the second terminal is inserted into a proper position in the second terminal receiving slot.
