Abstract

PURPOSE:To improve the assembling operability by providing a stage caulking and fixing an input terminal to a base of an input stage section chamber and a stage assembling a sub-assembly for input stage where a circuit component is assembled and wired in advance into the input section chamber. CONSTITUTION:A shield section plate 2 to section chambers A'... is soldered in the base 1. Then the input terminal 7 is caulked and fixed to the base 1. It is not required for the necessity of soldering by means of the fixing through the caulking, the terminal 7 is fixed stably and the reliability is improved. Then the input circuit sub-assembly 11 where the circuit component 10 and a minute sectioning shield section plate 2' are fitted onto a board 5 is prepared, the sub- assembly 11 is assembled into the input stage section chamber A' being a space in the base 1 and soldered so as to complete the input stage sectioning chamber A'. The input terminal of caulking type is cheaper than the terminal of screw tightening type, the terminal is fixed to the base with one-touch and the assembling operability is improved.

Because it is attached to a station, if you temporarily fix the input terminal (4) to the base + 1) by caulking it, you can put the jig for 17th into the narrow man-made construction section A, which is divided into a section, and it can be shortened and carried out. I am trying to fix the input terminal (4) by screwing it with a Nando (6), which can fit even in a narrow space. Input terminal (4) V is likely to cause some slowness due to external force during use. A (I- As a way to prevent this, the base (
1) is fixed by soldering, but this makes assembly work worse than V, and also input terminal (4) t.
As a means of caulking and fixing it to the base (1), resin molding is applied to the bypass filter (HPJ') and low pass filter (Lpi), which are input circuit groove components.
≦There is a product that uses a commercially available 2σ product and widens the gap between the circles in the heeling step section 9, making it easier to insert the caulking jig. However, CATV says that Afc quilters made of resin mold/components are unstable because they do not have side paths.
It was unsuitable for the input circuit of the converter, and the implementation was futile.

The assembly order of the converter's manual installation section is tχ! :The input terminal of the 0-sword clamping type that provides the manufacturing method of 9* is caulked and fixed to the base, and then the shield Ii is divided into a section with the circuit components of the manual stage on the Ffr desired board. The power plate is assembled by assembling the wired input membrane circuit components into the sub-assembly body t base to form the input circuit chamber.In this way, the input terminals are fixed to the base when the input stage compartment is empty. Therefore, it is possible to perform fixation by caulking with a J pin.
The six compartments other than the manual compartment will be constructed in the same manner as before.
