An electrical junction box can include a case, a substrate connector, and a substrate. The substrate is temporarily fixed and soldered to the substrate connector. The substrate connector and the substrate are stored in the case. The substrate connector includes a pair of shaft-shaped temporary fixing protrusions. Each of the temporary fixing protrusions includes a positioning shaft that positions the substrate and a temporary fixing shaft that prevents the temporary fixing protrusions from coming loose from the substrate. The temporary fixing protrusions can be fitted into fitting holes in the substrate.

Electrical junction box

An electric junction box that can accommodate various circuit patterns in accordance with a combination of a printed-circuit board and a case housing the printed-circuit board. Connection pins connected to conductors are provided in a projecting position at intervals along the peripheral edge of a printed-circuit board. An opening corresponding to the printed-circuit board is formed in a central region of the upper side of a case. Connector joints are positioned on the peripheral walls of the four sides of the case, and L-shaped terminals are provided at the same intervals as for the connection pins along the opening. Additionally, a connection structure of a tuning-fork terminal includes a tuning-fork terminal at the end portion of a conducting plate base bent vertically and having a press connection slot in the center of the vertical portion; and a tab-shaped mating terminal electrically connected to contact portions projecting from inner sides of the slot.

An electrical connector housing includes a lower shell, a connector block and an upper shell. An upper panel of the lower shell includes a first fixing mount and a draw hole, and the upper shell includes an outer side face having a second fixing mount. The upper panel of the lower shell has an inner face including a rib which is placed near the draw hole and extends towards the side panel of the lower shell while surrounding the draw hole. Likewise, the upper face of the connector block includes a pair of partition walls at a position corresponding to that of the rib, so that, when the connector block is inserted into the lower shell, the partition walls are closely superposed on the rib, and a draining space is formed away from a space for fixture ports for electrical parts, and leads to the drain hole. Such a configuration prevents the electrical connector housing from becoming too large and too costly. Such a housing structure also provides a better waterproofing quality.

An electrical connection box assembly provided with a projection extending outwardly thereof. The projection is preferably in the shape of a semi-circular channel and a wiring harness passes from electronic devices within the box, through a cut out in the front wall, and rests in the semi-circular channel. It is retained in the channel by a tie strap which is located between two retaining elements spaced apart approximately the width of the strip and forming planes parallel to the front face of the box. In this manner, the tendency of the strap to slide along the projection is eliminated and the strap can be tightened by pulling straight up thereon, thereby minimizing the space needed under the hood to install the device.

Electrical connection box assembly

An electrical connection box assembly which is provided with a projection extending outwardly of the body and located on the front wall at an angle thereto. The projection tapers from its proximal end adjacent the front wall toward the distal end remote therefrom. Thus, after the wire harness is placed in the projection, a tie strap is tightened therearound. The tapered configuration of the projection urges the tie strap toward the retaining element located adjacent the distal end. Thus, the wire harness can be reliably and securely fixed in its desired position.

An electrical assembly including a connection box and a junction block. The connection box has an electrically conductive plate mounted on one wall which is connected to a source of electricity through an external supply section. The junction block has a plurality of electrical elements on one side and a power transmission section on the other. The latter is electrically conducted to the conductive plate by a transmission harness. Electrical power flows from the source, through the supply section, through the conductive plate, through the transmission harness, and to the electrical elements. The supply section is in the form of a single cable, as is the transmission harness. A generally rectangular attachment section is part of the supply section and receives the head of the fixing bolt and retains it therein. The head of the fixing bolt is inserted into a generally rectangular attachment section and a nut is screwed on the opposite end, thereby clamping the entire supply section together. This provides excellent contact and connection, with a minimum of difficulty in assembly.

An electrical connection box having an L-shaped rib on the inside wall of its lower cover to engage a fitting projection located on the bottom face of an electrical unit housed within the box. The connection between the side wall of the lower cover and the electrical unit reinforces the area adjacent the notch through which the wires pass and securely maintains the electric unit inside the box.

An electric connection terminal can prevent electric ereosion caused in some equipment made of an aluminum material and attached to a car body for electric conduction of the equipment through the terminal such as an earth bracket which connects an earth line to the car body. The terminal comprises a first attaching member (1) made of an aluminum material and having a connecting portion (4) of a car body at the top end and a coupling portion (6A) at the bottom end, a second attaching member (2) made of a brass material and having a connecting portion (5) of an earth line at the top end and a coupling portion (6B) at the bottom end, and a water-proof layer (3) molded by a plastic resin for interconnecting said coupling portions (6A, 6B) of said first and second attaching members (1, 2) by embedding said portions (6A, 6B) in the plastic resin.
