1. A vehicle condition detection device comprising a secondarily molded body in which a connector housing portion and a device fastening portion are integrally formed by subjecting a resin-molded primarily molded body to a secondary molding process, under a condition where a detecting element for detecting a vehicle condition is mounted on a lead frame,
wherein a hollow portion within the connector housing portion formed by the secondary molding process is penetrated to a face area of the primarily molded body corresponding to a position of the detecting element to be interposed in the hollow portion.
2. The vehicle condition detection device according to claim 1, wherein a positioning guide for determining a position to be mounted to a sliding mold is provided on the primarily molded body to surround the face area of the primarily molded body corresponding to the position of the detecting element.
3. The vehicle condition detection device according to claim 2, wherein the positioning guide is formed in a rib shape.
4. The vehicle condition detection device according to claim 2, wherein the primarily molded body is provided with a groove enclosing the face area of the primarily molded body corresponding to the position of the detecting element inside the positioning guide.
5. The vehicle condition detection device according to claim 1, wherein a lead terminal from the detecting element that is extended from the primarily molded body and disposed within the connector housing portion, and a connector terminal to be connected with a connector as the counterpart are integrally formed by a lead frame.
6. The vehicle condition detection device according to claim 5, wherein the lead terminal and the connector terminal are formed flush with each other.
7. The vehicle condition detection device according to claim 5, wherein the lead frame has a turned-back portion formed such that the side thereof opposite from the connector terminal is extended to cover the detecting element.
8. The vehicle condition detection device according to claim 5, wherein the lead frame has a turn-raised portion around the periphery of the primarily molded body corresponding to the position of the detecting element.
9. The vehicle condition detection device according to claim 1, wherein the secondarily molded body has a reinforcing member made of a material that is higher in Young’s modulus than that of the resin of the secondarily molded body, and that is interposed between the detecting element and the device fastening portion.
10. The vehicle condition detection device according to claim 9, wherein the reinforcing member is formed by an expansion portion that is provided to the primarily molded body and made of the same material as that of the primarily molded body.
11. The vehicle condition detection device according to claim 9, wherein the reinforcing member is formed by an expansion portion that is provided to a metal cylindrical component used for the device fastening portion provided in the secondarily molded body and made of the same material as that of the component.
12. A method of manufacturing a vehicle condition detection device comprising the steps of:
setting a primarily molded body formed by a primary molding process between a pair of gripping members of a sliding mold to be temporarily held, under a condition where a detecting element for detecting a vehicle condition is mounted on a lead frame;
setting in a lower mold the primarily molded body temporarily held by the sliding mold;
performing a secondary molding process by mating an upper mold corresponding to the upper side of the lower mold therewith and injecting a resin into the molds; and
pulling out the sliding mold from a secondarily molded body released from the upper and the lower molds,
wherein a trace formed by pulling out of the gripping members of the sliding mold is a hollow portion penetrating from the interior of the connector housing portion to a face area of the primarily molded body corresponding to the position where the detecting element is disposed.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An electronic device comprising:
a first housing that includes an inlet and an outlet on one end;
a second housing; and
a linkage section that links the second housing to the first housing such that the second housing can be opened and closed, wherein
the linkage section holds the second housing so that the second housing is rotatable around a rotation axis which passes through the one end of the first housing,
when the second housing is closed, the second housing covers a top surface of the first housing except for a region on the top surface which is positioned above the rotation axis and extends along the rotation axis, and when the second housing is opened, the second housing is rotated to be away from the top surface,
the outlet is exposed both when the second housing is closed and when the second housing is opened, by being arranged on a back surface of the first housing which contacts with the top surface by a common side of the back surface and the top surface and which extends along the rotation axis, and
the inlet is exposed both when the second housing is closed and when the second housing is opened, by being arranged a distance away from the outlet, on a boundary region between the back surface and the region on the top surface.
2. The electronic device according to claim 1, wherein the inlet is positioned above the outlet on the one end.
3. The electronic device according to claim 1, wherein the one end of the first housing provided with the inlet and the outlet is an end side provided with the linkage section on the first housing.
4. The electronic device according to claim 1, wherein the first housing contains a main processing circuit and a cooling fan that cools the main processing circuit using the inlet and the outlet; and the second housing is a display section of the electronic device that displays a result of processing by the main processing circuit.
5. The electronic device according to claim 1, further comprising a keyboard on a top surface of the first housing.
6. The electronic device according to claim 1, wherein
the first housing is a main section of the electronic device containing a main processing circuit; and
the inlet is positioned in the first housing such that the inlet is above the main processing circuit and exposed while the second housing is closed.
7. The electronic device according to claim 1, wherein the outlet is arranged on only the back surface of all surfaces of the first housing including the back surface, the top surface, and two side surfaces each of which contacts with the top surface by a common side of the top surface and the each of the two side surfaces and contacts with the back surface by a common side of the back surface and the each of the two side surfaces.
