[Technical field to which the invention belongs]

 The present invention relates to a lead wire mounting structure and a spacer for mounting a lead wire such as an anode lead wire extending from a CRT or the like using a spacer.

[0002]

[Prior art]

 Conventionally, as a spacer for attaching a lead wire, for example, as shown in FIG. 3, a substantially circular outer frame 101, a plurality of ribs 102 provided radially inward from the outer frame 101, and A spacer 105 comprising a hole 103 formed at the center for attaching the lead wire 110 and a substantially V-shaped opening 104 for inserting the lead wire 110 is used. The lead wire 110 is attached by inserting the lead wire 110 into the opening 104 and fitting it into the hole 103.

However, in the conventional spacer 105, even after the lead wire 110 is inserted into the hole 103 and sandwiched, the open portion 104 remains open, so that the lead wire 110 comes off from the open portion 104. There was a problem that would. Further, in order to prevent the lead wire 110 from coming off from the hole 103, a wire clamp may be performed to prevent the lead wire 110 from coming off. However, in this case, there is a problem that the work of wire clamping is troublesome. Further, since the outer frame 101 has a substantially circular shape, it is necessary to open the outer frame 101 when the lead wire 110 is inserted into the hole 103 from the open portion 104. There was a problem that stress was applied to 101.

As a conventional technique described in Japanese Utility Model Laid-Open No. 3-24286, as shown in FIG. 4, an anode lead wire 203 is pulled out from an anode 205 of a CRT 202 and is connected to a flyback transformer 201 on a printed circuit board 204. There is a connection example. However, in this case, since the spacer for holding the anode lead wire 203 is not used, the anode lead wire 203 may be unstable because the anode lead wire 203 may come into contact with other electric components. There was a problem that it would be in a state.

In addition, Japanese Utility Model Laid-Open No. 2-92649 discloses an anode cap mounting structure. As shown in FIG. 5, in the anode cap mounting structure in which the anode cap 301 is mounted on the cathode ray tube 308, the outer wall of the cathode ray tube 308 is formed around the convex anode electrode portion 310 provided on the surface of the cathode ray tube 308. A cylindrical portion 312 is integrally formed to protrude, and an insulating cover 304 covering an outer peripheral portion of the cylindrical portion 312; a terminal base 306 formed on an inner surface of the insulating cover 304 and inserted into the cylindrical portion 312; An anode cap 301 including an anode terminal 307 formed at the tip of the base 306 and connected to the anode electrode 310 is fixed to the cylindrical portion 312. However, this has a problem that the structure is complicated. In addition, this is for mounting the anode cap 301, and since the anode lead lead 302 is in a free state, there is a problem that the anode lead lead 302 may come into contact with other electronic components or the like. Was.
