Title:
STRUCTURE OF TUNER AND TUNER FOR CABLE MODEM USING THE STRUCTURE
Document Type and Number:
Japanese Patent JP3411461
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize miniaturization and to improve intensity by providing projecting drawing part and an external drawing part on the short side of the chassis of a chassis angle to which an F-type connector is fitted and setting the external diameter of the contact face of the chassis of an input connector to be larger than the thickness of the chassis angle.
SOLUTION: A notch part 52 and the external drawing part 19 are constituted in abutting forms and they realize the structure of a thin tuner having an external form which does not exceed the projecting height of the external drawing part 19. The projecting drawing parts 17 and 18 are formed in almost arc shapes against the peripheral circle of the F-type connector and have the forms for increasing mechanical strength. The mechanical strength of the structure of the tuner is increased by the external drawing part 19 and the projecting drawing parts 17 and 18. When the dimension of the contact face of the F-type connector 50 to the chassis is set to be A and the thickness of thee chassis angle to be B, the relation is set to be A>B. Thus, the structure of the tuner, in which the thickness of the chassis angle is small and the chassis strength is large can be obtained.
