Abstract
A flyback transformer includes a casing and a coil-block accommodated in the casing. The casing has a guide opening communicating between inside and outside of the casing. The coil-block has a tongue portion which is formed with an opening. A cap member made of brass is supported in the opening of the tongue portion with an opening of the cap member being in alignment with the guide opening. The outside of the cap member is electrically connected to a wire extending from the coil-block and inside the cap member fittingly receives a lead wire which has been inserted into the casing through said guide opening.
Claims13
A electrical connecting apparatus for use in effecting an electrical connection between an electrical device positioned within a casing and a lead wire extending from said casing, said electrical connecting apparatus comprising:
- a chamber formed within a casing, said device being positioned within said casing, said casing having at least one guide opening that communicates from the chamber to the outside of said casing;
- a tongue portion extending from said device, said tongue portion having an opening defined therein, said opening being in alignment with said guide opening;
- a cap member made of an electrically conductive material and having a body portion and a bore defined therein, one end of said bore being opened, said cap member being inserted into said opening of said tongue portion with said open end of said bore facing said guide opening;
- electrical connecting means for connecting said cap member and said device;
- wherein a lead wire extending from the casing has one end portion inserted into said bore through said guide opening for effecting an electric connection between said lead wire and said device, and the other end portion of said lead wire extending outwardly from the casing;
- and
- a cast-in material injected into said chamber.
A flyback transformer comprising:
- a casing having a chamber formed therein and at least one guide opening that communicates from the chamber to the outside of said casing;
- a coil-block housed in said chamber of said casing, said coil-block comprising:
- (i) at least one bobbin having a tongue portion extending from said bobbin, said tongue portion having an opening defined therein, said opening being in alignment with said guide opening;
- (ii) a series of coils wound on said bobbin;
- (iii) a cap member made of an electrically conductive material having a body portion and a bore defined therein, one end of said bore being opened, said cap member inserted into said opening of said tongue portion with said open end of said bore facing said guide opening;
- and
- (iv) electrical connecting means for connecting said cap member and one of said coils;
- lead wire having one end portion inserted into said bore through said guide opening for effecting an electric connection between said lead wire and said coil, and the other end portion of said lead wire extending outwardly from the casing;
- and
- a first cast-in material injected into said chamber.
