Abstract

An SD card (1) includes a card-shaped housing (4) which is formed by assembling insulating upper and lower covers (2 and 3), and a circuit board (5) which is accommodated in the housing (4). The circuit board (5) extends along an inner wall (2a) of the upper cover (2). Terminal electrodes (6) are fixed near one side end of the lower cover (3) by insert molding and are exposed to the outside, and reinforcing ribs (3d) configured to make contact with the circuit board (5) are formed thereon. Wiring patterns are formed on the circuit board (5), and electronic components (8 and 8a) are mounted on a principal surface (5a). Elastic pieces (9) which extend from the terminal electrodes (6) to the inside of the housing (4) are in elastic-contact with connecting land portions (7) of the wiring patterns disposed at one end of the principal surface (5a).

Claims

1. A card-type electronic circuit module comprising:

a circuit board on which wiring patterns are formed and electronic components are mounted;

an insulating housing in which the circuit board is accommodated;

terminal electrodes which are fixed near one side end of the housing and exposed to the outside; and

conductive internal connection means for realizing conduction between the terminal electrodes and the wiring patterns within the housing,

wherein the circuit board is extended along one of mutually facing inner walls of the housing, and the internal connection means are in elastic-contact with connecting land portions of the wiring patterns disposed at one end of the principal surface of the circuit board.

2. The card-type electronic circuit module according to claim 1, wherein the terminal electrodes are fixed to the housing by insert molding.

3. The card-type electronic circuit module according to claim 1, wherein the internal connection means are realized by elastic pieces which extend from the terminal electrodes to the inside of the housing, and distal ends of the elastic pieces are in elastic-contact with the connecting land portions.

4. The card-type electronic circuit module according to claims 1, wherein reinforcing ribs which protrude from the vicinity of the terminal electrodes and make contact with the principal surface of the circuit board are formed on the housing.

5. The card-type electronic circuit module according to claim 2, wherein the internal connection means are realized by elastic pieces which extend from the terminal electrodes to the inside of the housing, and distal ends of the elastic pieces are in elastic-contact with the connecting land portions.

6. The card-type electronic circuit module according to claim 2, wherein reinforcing ribs which protrude from the vicinity of the terminal electrodes and make contact with the principal surface of the circuit board are formed on the housing.

7. The card-type electronic circuit module according to claim 3, wherein reinforcing ribs which protrude from the vicinity of the terminal electrodes and make contact with the principal surface of the circuit board are formed on the housing.
