Abstract: A dome switch includes a front sheet (22) which protrudes outside and can be reversed inside and has dome-shaped protuberances (27), each protuberance having an electrode provided therein; an FPC (24) serving as a circuit member having contact points (32), the electrodes of the protuberances being brought into contact when the protuberances (27) are reversed; and a spacer sheet (23) for preventing occurrence of deformation of the front sheet (22) which is to be interposed between the front sheet (22) and the FPC (24) and has through holes (29) formed therein for ensuring contact between the electrodes and the contact points (32). The spacer sheet (23) is caused to act also as a member for ensuring a stroke dimension of the protuberance (27).

Abstract: In a dome switch (21) including a surface sheet (22), a spacer sheet (23), an FPC (24) serving as a circuit member, and an adhesive sheet (25), an accommodating portion (34) for a chip component (38) mounted on a contact (37) side of the FPC (24) is formed in the spacer sheet (23). In addition, an embossed portion (28) for the chip component (38) is formed in the surface sheet (22), as required.

Abstract: A circuit member-holding clamp (A1) is formed of a flexible resin material molded on a plurality of juxtaposed circuit members (W) in intersecting relation thereto, and the circuit member-holding clamp has such a configuration that a plurality of tubular portions (10), respectively surrounding the circuit members (W), are integrally connected together. Preferably, a thin wall portion (11) is formed between any two adjacent tubular portions (10). In a method of producing the circuit member-holding clamp (A1), the plurality of circuit members are inserted in a mold, and a flexible resin material is poured into the mold.

Abstract: Band bodies (31) of bendable harness fastening and fixing bands (30) are formed integrally on the vicinity of an outer surface of a duct partition wall (22a) of an air duct (21) on an instrument panel (20) of a vehicle body. First band retaining rings (24) are formed respectively on those portions of the instrument panel (20) corresponding respectively to the band bodies (31), and second band retaining rings (25) are formed on the outer surface of the air duct partition wall (22a). A series of catching notches (32), arranged in a one-way notched arresting manner, are formed on a reverse surface of the band body (31), and each of the first and second band retaining rings (24) and (25) have a lock portion for engagement with the catching notches (32) to prevent the backward movement of the band body. Any one of several kinds of wire harnesses (40) to (42) of different diameter can be fixed by the use of the first band retaining rings (24).

Abstract: A wire harness fixing structure in an instrument panel, as well as an instrument panel, in which the wire harness can be easily fixed without the use of an adhesive or separate members such as clips, mounting error can be absorbed when fixing the wire harness, and water due to dew condensation and so on can be easily discharged. In the structure for fixing the wire harness (23) in an instrument panel (21), a harness fixing portion (25), including an opening (26) and a fixing portion (27), is provided at a harness installation passage (24) formed in parting engagement surfaces of upper and lower instrument panel members (2) and (22) jointly forming the instrument panel (21), and the harness fixing portion (25) fixes a wire harness (23) installed in the harness installation passage (24). The opening (26) of the harness fixing portion (25) serves as a discharge port for discharging water due to dew condensation, developing in the harness installation passage (24).

Abstract: A wire-harness mounting structure for mounting wire harnesses of several types with different diameters by making effective use of, for example, a recessed portion between air duct partition walls in an instrument panel of an automobile. By making use of a recessed portion (23) which is located between duct partition walls of an air duct (20) provided in an instrument panel of a vehicle, a harness resilient retaining portion (30) is integrally fixed in the recessed portion (23). A slit (31) is provided in the harness resilient retaining portion (30) in such a manner as to extend from one end side toward the other end side thereof. Each of wire harnesses (40 to 43) of several types with different diameters is resiliently clamped through one-touch fitting in a stepped portion of several stepped portions (32 to 34) of the slit whose slit widths (B1 to B3) become consecutively smaller.

Abstract: A clip mounted with a mounting plate having opposite walls defining a mounting groove having an opened leading end, the clip is disclosed which has a clip body made of an elastic metal plate, having a V-shape portion with substantially V-shape cross section formed by folding back so as to have two opposite inclined plate portions, the inclined plate potions having opposite slits, respectively, the opposite walls of the mounting plate inserted into the slits, respectively, when the clip body is inserted into the mounting groove from the leading end of the clip body, so that the opposite walls of the mounting groove are inserted into the slits, the mounting plate is engaged with the slits, and a slit start portion adjacent to the leading end of the V-shape potion is elastically supported by the opposite walls of the mounting plate with an elastic force of the opposite inclined plate portions; and a base having a clip-body holding portion for holding the clip body, a harness securing portion which is made of res

Abstract: A disconnection mechanism for a dark current fuse provides a connecting terminal connecting the dark current fuse, a fuse block body receiving the connecting terminal, and a fuse holder slidably engaged with the fuse block body in a direction of connecting the dark current fuse, the fuse holder provides a cutaway opening exposing a head of the dark current fuse being therein, an engaging projection disposed at an opening edge of the cutaway opening for engaging the head, and a supporting wall portion contacting a trunk of the dark current fuse. The disconnection mechanism is not necessary to store the extracted dark current fuse after a dark current fuse circuit is opened, so that there arises no possibility of missing the extracted dark current fuse, the dark current fuse can be extracted by using a puller, and the dark current fuse is surely held with being prevented from slipping off.
