A first cover body has a first space defined by peripheral walls. Each of a plurality of protruded portions has a through hole, and is outwardly protruded from at least one of the peripheral walls so as to define a groove communicated with the first space and the through hole. Each of a plurality of retainers is provided with one of the protruded portions. A second cover body is fitted with the first cover body so as to close the first space, while being retained by the retainers. A plurality of projections are provided on an outer periphery of a third cover body. The third cover body is disposed in the first space such that each of the projections is fitted into the groove so as to partition the first space from the through hole.

Waterproof structure of electric junction box

A connector includes first wire-holding portions ( ) for holding power-supplying wires ( ) in a juxtaposed manner, a second wire-holding portion ( ) for alternately holding earth wires ( ) and signal-purpose or power-receiving wires ( ) for auxiliary equipments in a juxtaposed manner in a direction substantially perpendicular to a longitudinal direction of the wires ( ) held by the first wire holding portions ( ), a plurality of press-contacting joint terminals ( ), each including a second press-contacting terminal ( ) for connection to the corresponding signal-purpose or power-receiving wire ( ) and a first press-contacting terminal ( ) which is connected to the second press-contacting terminal ( ), and can be connected to the corresponding wire ( ) held by the first wire-holding portions ( ), and an earth terminal ( ) which can be connected to the earth wires ( ) and can be connected to an earth side.

Joint connector

An electrical connection box for a vehicle has a body and a power distribution element. A portion of the body upstanding from one face receives, in use, an electrical component such as a relay which at a fastening location is joined to the distribution element. A casing covers the component receiving portion. To reduce the risk of accidental contact with the fastening location, the box has a removable U-shaped cover covering the fastening location, the cover being enclosed within the casing. The cover has an aperture through which the electrical component projects, and the periphery of the aperture may contact the component receiving portion or the electrical component.

Electrical connection box including removable cover enclosed within a casing

A wire harness assembly including a wire harness and a junction box. The junction box contains a plurality of junction box terminals and it also carries an attachment unit projecting outwardly. The attachment unit has a plurality of openings in its outer surface through which the junction box terminals project. One end of the terminals is in contact with the internal circuit of the junction box and the other is a pair of cutting blades into which the wire is inserted. An intermediate section of the wires is attached in accordance with the foregoing, and the ends are inserted into a plurality of connection boxes. The openings may be in multiple rows, offset transversely from each other. This permits inclusion of a large number of terminals in a relatively small space.

Wire harness assembly

A terminal assembling structure includes a terminal metal fitting having a tinning layer on a surface thereof, a connecting portion overlapped with the terminal metal fitting, and a fastening member fastening the terminal metal fitting and the connecting portion. An adhesion phenomenon of metal is generated between the terminal metal fitting and the connecting portion by the fastening of the terminal member.

Terminal assembling structure and method

In a terminal metal fitting assembling structure (10,30), a projecting portion (45) is provided on a plate-like overlap portion (32) which is formed on a second terminal metal fitting (30). In addition, the position of the projecting portion (45) is set outside an area (A) of the overlap portion (32) that is overlapped by a head portion (50A) of a tightening bolt (50). Due to this, when the terminal metal fittings (10,30) are tightened by the tightening bolt (50), a plate-like overlap portion (12) formed in the first terminal metal fitting (10) is flexibly deformed and is pressed by the projecting portion (45) against the plate-like overlap portion (32) of the second terminal metal fitting (30), so that the two terminal metal fittings (10,30) can be strongly contacted with each other by the resilient force generated by the flexibly deformed plate-like overlap portion (12). This makes it possible to increase the contact pressure between the two terminal metal fittings. Still further, since the projecting portion (45) is not tightened directly, even if the two terminal metal fittings are tightened excessively by the tightening bolt, the projecting portion (45) can be prevented from being crushed.
