Abstract

PURPOSE:To eliminate a useless space of a titled radio equipment and to fold it up to a small size by preparing a printed circuit substrate by using a flexible material as the base, and fitting electronic parts and function parts to said substrate, and folding it up. CONSTITUTION:A printed circuit substrate 4 is prepared by a flexible substrate which has a branch part 5 projected at a right angle on one end and whose whole body is made of polyester resin, etc. as the base. Subsequently, necessary electronic parts and function parts are fitted to this substrate 4, and thereafter, it is bent to a square shape, also the branch part 5 is bent in a channel shape, and a plane loudspeaker 15, a battery 16 and a memory capsule 17 are connected and installed. In this way, a compactly bent chassis 21 is stored in a case body 2 and a cover 3 of the case.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention can be applied to radio equipment using a flexible printed wiring board for the chassis, such as radio receivers, transceivers, and remote controllers.

Conventional configurations and their problems Radio equipment such as radio receivers and transceivers must be small, lightweight, and multifunctional. It is necessary to rationalize the Also, from a manufacturing standpoint, it is required to be inexpensive and highly reliable. In conventional wireless devices, hard materials are used for the printed wiring board, so when it is housed in a case, there is wasted space between the printed wiring board and the case, which hinders miniaturization. There are problems in that the assembly process requires a lot of effort.

OBJECTS OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and provide a wireless device that is small and lightweight, requires no assembly effort, and can be manufactured at low cost.

Structure of the Invention The present invention uses a flexible double-sided printed wiring board, which is equipped with electronic components and functional components, and then folded.
A case that is housed in a case with a lid attached to the case body with a hinge so that it can be opened and closed freely, the operation section and display section are exposed on the top of the case body, and parts such as batteries and a part of memory are detachably attached to the lid. It is.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a perspective view of the exterior of a lighter-type radio receiver according to the present invention, FIG. 2 is a state in which the lid is open, and FIGS. 3 to 6 are a printed wiring board and its attachment. The second figure is a diagram showing the assembly process. In FIG. 1, (1) is a case, which is composed of a case body (2) and an M (3) attached to the case main body (2) so as to be openable and closable at the elbow portion, and the entire body is formed in the shape of a lighter case. In Figure 3, it is a (41i niblint wiring) wire board with a branch part (5) protruding at right angles at one end, the whole is made of a flexible board made of polyester resin, etc., and the circuit pattern is printed on both sides ( 6) is printed, and the necessary parts of the circuit pattern on both sides are connected through through holes.In manufacturing, as shown in the figure, multiple boards (4), (1ll) are made from one sheet of material. By making them continuously, there is no waste of material and mass production is possible.The circuit pattern (6) of the printed wiring board formed in this way has small integrated electronic components (as shown in Fig. 4). 7), (
8) and jack (9), and further, as shown in FIGS. 5 and 6, liquid functional parts are attached by soldering or adhesive. The movable piece ID of the switch is provided with a contact on the inside thereof, and the printed wiring board (4) has a fixed contact side at a position corresponding to this contact point, and the movable piece ID is provided in the direction of the arrow shown in FIG. The circuit is configured to turn on when - is pressed. The movable piece (b) shown in Fig. 7(c) is a switch with a similar structure, and the movable piece 08) can be moved in the direction of the arrow with your finger.
When you press , contact α9 glued to the movable piece (to) connects to the circuit (
A), (20) are short-circuited and turned on.

After attaching the required electronic components and functional components to the printed wiring board (4) and its branches (5) in this way, as shown in FIG.
), the substrate (4) is (4a), ('ib), (
IIc), (4d) into a square shape, and as shown in the same figure (b), the branches (5) are folded into (5a), (5b).
, (5c) are bent into a U-shape, a flat speaker (to) is connected and mounted on the (lid) surface, and a battery μs and a memory capsule 07 are connected and mounted on the (5a) surface. The chassis ■p folded into a compact shape in this way is
As shown in the figure, insert the rectangular bent part (4) into the case body (2), and then insert the U-shaped bent part (4) into the case body (2).
5) is stored in the lid (3) of the case. The stored state is shown in FIGS. 1 and 2. In the figure, (4) is a push button for operating the movable piece (G) of the switch shown in Figure 7 (c) from the outside, and the handle is an antenna that also serves as a design effect. 2) is attached diagonally to the front. In addition, as shown in the figure, the movable piece of the operation switch (11) and the i-indicated part α0 are located on the upper surface of the case body (2), and replaceable parts such as the battery α0 and memory capsule 07 are located on the lid (3). It is stored inside.

Effects of the Invention According to the present invention, since the printed wiring board is made of a flexible material, by attaching electronic components and functional components to it and folding it, it is possible to eliminate wasted space and make it compact. It can be folded, and since the folded printed circuit board is constantly trying to expand due to its elasticity, when it is stored in a case, it can be glued to the inner wall of the case and fixed using screws or other fixing means. It can be easily fixed to the case without needing to do so, which greatly reduces assembly man-hours. In addition, dry batteries that require replacement,
Since the memory capsule and the like are stored inside the lid of the case, it is easy to replace them.
