る。(Problems to be solved by the invention) In the case of the conventional terminal fitting a, three parts, the top plate d and the side plates e and f, must be formed from wide conductive thin plates, resulting in high material costs. Moreover, it requires bending of the side plates e and f and drawing of the circular tube h, which requires a large number of steps and is expensive. Also, the side plate f
It is almost impossible to precisely bend the material at the specified dimensional position, and there is usually a tolerance range of 0.3 mm forward and backward, for example. For this reason, it is necessary to form the metal fitting mounting hole c' with a considerable amount of play compared to the wall thickness of the terminal metal fitting a, and it is not possible to stably mount the side plate f in an accurate position via the sawtooth j. Further sawtooth
When fixing by press-fitting, if the male screw k is strongly tightened, play may occur in the terminal fitting a, and if a large number of terminal fittings a are press-fitted, the bottom of the insulating base b will be There is a risk that it will warp a little and create a gap between it and the printed circuit board or chassis to which it is attached. Furthermore, in the conventional example, the terminal fitting a is screwed into the circular tube h, and the male metal screw k is screwed into the female screw i, that is, the male metal screw k is screwed only into the female metal screw, so vibrations are generated in the terminal block. When an impact occurs, the vibration force and impact force applied from the female thread i to the male thread k are large, and there is a risk that the male thread k may loosen, so a spring washer l is used.

Therefore, the terminal block itself can be provided at low cost. In addition, the conductive flat plate used in this invention is embedded and fixed as an insert fitting into the insulating base by simultaneous molding, so the terminal fitting can be installed in an accurate position extremely reliably, and the male screw can be inserted into the insertion groove. Even when screwed in, there is no risk of play in the terminal fitting, and unlike conventional press-fit types, there is no risk of deformation such as the bottom surface of the terminal block becoming warped. Furthermore, in this invention, the male screw is made of metal, the insulating base is made of plastic, and the male screw is screwed into both the insertion hole of the plastic and the insertion groove of the terminal fitting, so there is no vibration to the terminal block. Even if an impact occurs, the vibration force applied from the plastic female screw to the metal screw,
The impact force is smaller than the conventional case from a metal-only female thread to a metal male thread, and there is almost no risk of the metal male thread coming loose, and there is no need for a spring washer. Since the internal thread is inserted, the internal thread will not be damaged, and it is strong and can withstand use over time.

As shown in the figure, when the conventional example is soldered to the printed circuit board 15, there is a large play in the fitting mounting hole c', and the solder 17 flows into this, causing the base b to burn and be damaged. Since the metal fitting 4 is simultaneously molded as an insert metal fitting, the 4th and 5th
As shown in the figure, there is no gap between the front and rear of the extending portion 10, so there is no risk of solder flowing in, and the base will not be damaged.

Comparing the case where 1 is formed long and bent at right angles with the conventional example, the following effects are obtained. 10th
As shown in the figure, in the case of the conventional example, there is no choice but to provide a large amount of play in the fitting mounting hole c', so if you try to bend the terminal leg g at a right angle after attaching the terminal fitting a to the base b, the chain line Moreover, each terminal leg g is bent at an irregular angle, making it difficult to insert into the hole of the printed circuit board, making it unstable and inaccurate. On the other hand, in this embodiment, the terminal leg 11 can be accurately bent as shown by the two-dot chain line in FIG. 4, and can be reliably attached to the hole 15' of the printed circuit board 15.
