JPS5915476Y2 - Through-type porcelain capacitor for terminal use - Google Patents

Description

[Detailed description of the invention] This invention relates to the improvement of a through-type ceramic capacitor that also serves as a terminal and is used for noise prevention in radios, stereos, motors, etc., and bypass circuits in FM, TV tuners, etc.

Conventionally, some types use a cylindrical dielectric body and have a two-pronged claw at one end of the inner terminal that penetrates the inner hole, and others have a hole drilled at one end. If the lead wire is passed between the two prongs or through the hole and perpendicular to the inner surface terminal, it may become unstable, and unless the lead wire is wound, there is a fear that the lead wire cannot be attached firmly enough.

Wrapping the lead wires around increases the number of man-hours, and even if it becomes necessary to make corrections, there are problems such as making it almost impossible to do so.Also, when using the wire as a terminal, it is difficult to attach a large number of lead wires at the same time. There was a risk that the attachment part would become weak.

The purpose of this invention is to solve the above points,
Even when a large number of lead wires are attached to the inner surface terminal with grooves in three directions at the end on the side where the lead wires are attached, the lead wires are passed through almost uniformly regardless of the direction. To be able to easily and firmly attach a wire to an inner terminal without getting the wire tangled in a nail.

Another purpose is to prevent solder leakage when soldering lead wires.

Still another object is to prevent the internal terminal from slipping when installed in the inner hole of the insulator or dielectric.

To explain this invention with reference to the attached drawings of the embodiment, three fork-shaped claws 1a are attached to the upper end of the T-shaped metal plate 5.
1b and 1a are provided, a cut-and-raise claw 1d is provided near the lower end, and the metal plate 5 is bent in half in the vertical direction of the leg portion 7 to form a gutter-shaped inner surface terminal 1. This is a through-type ceramic capacitor that also serves as a terminal, in which the inner surface terminal 1 is fitted into the inner hole of a cylindrical insulator or dielectric 3.

Reference numeral 2 denotes a ring-shaped external terminal, which is used to attach the through-type ceramic capacitor that also serves as a terminal to a metal wall 8 of a housing or the like.

Reference numeral 4 denotes a portion that constitutes the horizontal groove 1C of the inner terminal 1, which is a notch formed by the three claws 1a, 1b, and 1a of the metal plate 5.

Reference numeral 6 denotes a vertical upper groove of the inner surface terminal 1.

The present invention is as described above, and includes fork-shaped three-pronged claws 1a and lb provided at one end of a gutter-shaped inner terminal 1.

Through the two grooves 1c and lc formed by 1a and the three-way groove formed by the upper groove 6, a large number of lead wires are simultaneously passed vertically and horizontally without any direction and are soldered.

The claw 1b prevents melted solder from leaking out.

Furthermore, when the inner surface terminal is fitted into the cylindrical dielectric body, the cut and raised claws 1d open outward due to their spring action, thereby preventing the inner surface terminal from falling off.

This invention has three fork-shaped claws 1 at one end of the inner terminal 1.
Since a, 1b, and 1a are provided, a large number of lead wires can be attached at the same time without directionality, and there is no risk of solder leaking, so it can be firmly attached and can also be used as a terminal.

It is not necessary to wrap the lead wire around the nail, thereby preventing an increase in the number of man-hours, and when making corrections, the lead wire and the inner terminal are not damaged, and the work can be easily carried out with less man-hours.

Furthermore, since the cutting claws are provided, the inner surface terminal can be reliably fitted into the inner hole of the insulator or dielectric layer without fear of falling out.
