Abstract:
An electronic apparatus (100) includes a housing (10) a circuit board (20) held in the housing (10), and large electronic components (30,31) held in the housing (10) and electrically coupled to the circuit board (20). The housing (10) has a mounting surface (10a) and the electronic apparatus is mounted to an object at the mounting surface (10a). The large electronic components (30,31) are arranged in a three-dimensional manner with respect to the mounting surface (10a) in such a manner that at least one of the large electronic components (30) overlaps at least one of the large electronic components (30) in a direction toward the mounting surface.
Abstract:
The invention relates to circuit component locating apparatus used to locate a circuit component, such as a resistor, capacitor etc. on a circuit board. The apparatus has a fastening frame and an attachment member projecting there from. The attachment member extends around the circuit component to provide a gap which can receive adhesive means in order to secure the circuit component to the attachment member. The apparatus may be used on any circuit board, although it is particularly useful for minimising the effect of vibrations on circuit boards of an automobile's Engine Control Unit (ECU).
Abstract:
According to the present invention, there is provided a holder having a pressure flange not to be easily disengaged from a small-sized electronic part in pressing and accommodating the holder having the small-sized electronic part in a mounting recess. A holder (10) includes a projecting portion (16) protruding from a pressing flange (13) toward a cylinder axis of a holding portion (11), formed in a portion having a predetermined length of an inner edge (13a) of the pressing flange (13). With this construction, when the holder (10) accommodating a small-sized electronic part (6) is mounted to a casing of an apparatus, even if the pressing flange (13) is rolled up and about to be disengaged from the small-sized electronic part (6), the projecting portion (16) engages with the small-sized electronic part (6), thereby preventing the pressing flange (13) from being rolled up.
Abstract:
A wire management system (10) includes a first portion (12) and a second portion (14). The first portion (12) comprises a base pivot (16), a base socket (18), a mounting stud (20) and a mounting bolt (22) for fastening the wire management system (10) to an electrical component, such as a printed circuit board (11). The second portion (14) comprises a cable guide assembly defined by at least two non-conductive guide members (24) with locking notches (26) and a base member (28). The guide members (24) permit orientation of the wires (13) and/or cabling (15) in a generally vertical direction to minimize the heat build-up from a heat-emitting device (17). In another embodiment, the wire management system (100) includes a mounting stud (112) and an integral cable guide assembly that includes a base portion (102) and an upper portion (104) with at least two guide members (114) that may be removably mounted to the mounting stud (112). The at least two guide members (114) orientate the wiring and/or cabling in a generally vertical direction to minimize the heat build-up from the heat emitting device (17). In another embodiment, the wire management system (200) includes a relief cut (208) with breakaway portions (208a-208c) including at least a throat portion (216), a neck portion (218) and a beveled portion (206). In yet another embodiment, the wire management system (300) includes a base portion (302) supported by a rigid plate or washer (350).
Abstract:
A capacitor unit is provided, which has a long lifetime and is free from maintenance when it is used as an emergency power supply of electronic control braking system, etc. and in which weight load is not applied to a circuit board, high reliability in use under harsh vibration conditions is achieved, and short-circuit defect does not occur even when an explosion-proof valve operates. The capacitor unit of the present invention includes a plurality of capacitors, a circuit board on which a circuit pattern for connecting the capacitors is formed, and a holder sandwiching and retaining the body parts of the capacitors.
Abstract:
The invention relates to a method for fixing a miniaturised component (2), especially comprising a micro-optical element (3), to a pre-determined fixing section (7) of a base plate (1) by means of a soldered joint (6a). Said base plate (1) comprises an upper side (8) and a lower side (9), and the component (2) comprises a base surface (4). At least the fixing section (7) of the base plate (1) is coated on the upper side (8) by a metallic layer (5) which is applied at least in the fixing section (7) in a continuously plane manner and thus without interruptions. Solder material (6a) is applied at least to the fixing section (7) coated with the metallic layer (5). In one step of the method, the component (2) is arranged above the fixing section (7), the base surface (4) of the component (2) being positioned above the solder material (6a) in such a way that they do not touch, are vertically interspaced and form an intermediate region between each other. In another step, thermal energy is supplied, especially by means of a laser beam (11), in a region which is locally limited essentially to the fixing section (7), in order to melt the solder (6a) from the lower side (9) of the base plate (1), such that the intermediate region is filled by drop formation of the melted solder (6a'), fixing both sides.
