端子ピンである。 For example, in order to attach a heat sink on which a power transistor is attached to a printed board, and to electrically connect the heat sink, that is, the collector connected to the exterior case of the power transistor, to the conductive pattern on the printed board, the following procedure is generally used. I was doing it. That is,
In FIG. 1, when attaching the power transistor 1 to the heat sink 2, the terminal fitting 5 is screwed onto one of the mounting screws 3, 4 to attach the metal fitting to the heat sink 2. The terminal fittings 5 are soldered to the conductive pattern on the back side of the printed board 6, and the heat sink 2 itself is fixed to the printed board 6 with screws 7. In addition,
8 is a nut screwed onto the other screw 3, and 9 is a terminal pin of a power transistor led out from a hole 10 in the heat sink.

ていた。 By the way, in such a case, the soldering work of the terminal fitting 5 is carried out by so-called dipping together with other electrical parts (not shown) such as resistors and capacitors that are automatically inserted into the printed board 6, The tightening work of the screws 7 is performed in a subsequent manual process. For this reason, when the lower end surface of the heat sink 2 is not flat (roughly finished) during the above-mentioned dipping, as shown in FIG. The metal fittings 5 will now be soldered. Then, when the screw 7 is subsequently tightened, a pulling force acts on the terminal fitting 5 in the direction of the arrow, which causes the soldering part holder 12 to come off from the printed board 6 (so-called solder floating). occurs. For this reason, conventionally, in such cases, the terminal fitting 5
It was necessary to re-solder the parts by hand.
そこで、本考案はこのような点に鑑みなされた
ものであり、以下、本考案の一実施例を説明す
る。 Therefore, the present invention has been devised in view of these points, and one embodiment of the present invention will be described below.
即ち、本考案では第１図の端子金具５の代りに

を有するようにしたものである。 That is, the present invention is characterized in that a terminal fitting 13 as shown in FIG. 3 is used in place of the terminal fitting 5 shown in FIG. The terminal fitting 13 shown in FIG. 3 is made by bending a relatively soft thin metal plate with excellent solderability to form a U-shaped portion 13a, and providing a slit 13b in the U-shaped portion. It is designed to have a high degree of elasticity.

電パターンから脱れるのを防止できる訳である。 The terminal fitting 13 is attached to the heat sink 2 by screwing its screw hole 13C into one of the mounting screws 3 and 4 of the power transistor 1, as shown in FIG. It is soldered to the printed board 6 in the solder dipping process described above. This point is similar to the case of FIG. However, in the case shown in Fig. 4, when tightening the screw 7 after the above-mentioned dating, the above-mentioned force is applied to the terminal fitting 1.
3, this metal fitting 13 deforms as shown by the broken line, thereby preventing the soldered portion 12 from coming off the conductive pattern of the printed board 6.

用できる。 In addition, in this example, the case where separately prepared terminal fittings were attached to the heat sink was explained.
In addition, it is widely used when, for example, a flyback transformer, etc., a terminal provided integrally on an electrical component is soldered to a printed board, and then the component body is tightened and fixed to the printed board using screws. Applicable.
本考案は以上のように構成されたものであるか
