Abstract

A fuse holder component includes a bottom plate fixed to a printed board, and first and second side plates whose main body portions individually extend from side edges of the bottom plate. The second side plate includes a suction portion extending through an extension portion from the main body portion and provided with a suction surface to which a suction nozzle of a mounter is accessible. A pair of fuse holder components, surface-mounted on the printed board by using the mounter, constitute a fuse holder that stably holds a glass-tube fuse.

Claims

1. A fuse holder component formed as a single piece comprising:

a bottom plate adapted to be fixed to a printed board;

a first side plate having a main body portion attached to and obliquely extending from one side edge of said bottom plate upward and inward in a width direction of said bottom plate; and

a second side plate including a main body portion and a suction portion extending from an outer half of the main body portion,

wherein the main body portion of said second side plate cooperates with the main body portion of said first side plate to hold a cap of a glass-tube fuse, and the suction portion has a suction surface to which a suction nozzle of a mounter is accessible.

2. The fuse holder component according to claim 1, further comprising:

an extension portion extending from the outer half of the main body portion of said second side plate,

wherein the suction portion extends from the extension portion substantially in parallel to said bottom plate.

3. The fuse holder component according to claim 1, wherein said first side plate has a first guide portion extending outward in the width direction of said bottom plate from an inner half of the main body portion of said first side plate, and

said second side plate has a second guide portion extending outward in the width direction of said bottom plate from an inner half of the main body portion of said second side plate.

4. The fuse holder component according to claim 1, wherein a projection is formed in an upper face of a widthwise central part of an inner half of said bottom plate.

5. The fuse holder component according to claim 1, wherein said first and second side plates include connecting portions curved in transverse section and extending from the side edges of said bottom plate to the main body portions of said first and second side plates, respectively.

6. The fuse holder component according to claim 1, wherein said bottom plate is soldered to the printed board.

7. The fuse holder component according to claim 6, wherein notches are formed in axial ends of said bottom plate.

8. The fuse holder component according to claim 7, wherein the notches are formed into a semicircular shape as viewed in plane.

9. The fuse holder component according to claim 7, wherein said bottom plate is formed so that the axial ends of said bottom plate are located slightly outward with respect to axial ends of said first and second side plate, respectively, in an axial direction of said bottom plate.

10. The fuse holder component according to claim 1, wherein said second side plate has an engaging portion extending toward said bottom plate from an inner edge of the suction portion and adapted to be abutted against an axially outer end face of the glass-tube fuse.

11. The fuse holder component according to claim 10, wherein the width of the engaging portion is substantially half the width of the suction surface.

12. The fuse holder component according to claim 10, wherein the engaging portion is substantially flat.

13. The fuse holder component according to claim 10, wherein the engaging portion extends at a substantially right angle from the suction portion.

14. The fuse holder component according to claim 10, wherein the engaging portion extends at an obtuse angle greater than a right angle from the suction portion.
