The materials described in JP-A No. 1-126783, JP-A No. 63-265487 and the like are known, and these are generally constructed as follows. That is, a plurality of connector blocks are integrally formed in the upper case of the branch connection box, and a plurality of male terminals are press-fitted into the connector block and fixed in an upright state.

きく膨張あるいは収縮することになる。By the way, the printed circuit board is generally made of a thermosetting resin such as an epoxy resin as a main material, and is generally made of a thermoplastic resin such as a polypropylene resin as a main material. Have greatly different thermal expansion coefficients. Specifically, the coefficient of thermal expansion of the case may reach 5 times to 10 times that of the printed circuit board, and the printed circuit board hardly undergoes thermal deformation with respect to temperature changes, whereas the case made of resin does not. The case will greatly expand or contract.

まうという問題があった。However, since each male terminal of the connector is fixed to the upper case by press fitting and is also fixed to the printed circuit board by soldering, the male terminal is located at two points vertically apart from each other in the longitudinal direction. The upper case and the printed circuit board are simultaneously restrained. For this reason,
The stress caused by the difference in thermal expansion applied to the two points causes a problem that the male terminal is inclined and deformed, which makes it difficult to connect the connector.

As disclosed in Japanese Patent No. 16110, it is conceivable that the terminals are soldered to the printed circuit board while the insertion holes are formed in the upper case of the branch connection box so that the terminals can be freely inserted in an unconstrained state. However, if this configuration is adopted, the terminal will not be fixed to the upper case this time, so the fixing force of the terminal will be insufficient, and the terminal will wobble due to the force acting on the terminal when the connector is mated and unmated. Eventually, the terminals may be tilted to cause improper fitting.

続するようになっている。In the case 10, a rectangular printed circuit board 20 mainly made of epoxy resin or the like is used.
Is housed. The printed circuit board 20 has fixing holes 21 corresponding to the heat crimping projections 14 formed at the four corners thereof. It is fixed to the upper case 11 of the case 10. The printed circuit board 20 includes the connector block 1
The male terminals 22 are erected so as to correspond to No. 3. The male terminal 22 is manufactured, for example, by punching out a conductive metal plate, and is provided with three supporting leg portions 22b, which are branched into three or three, in a row at the lower end of the terminal main body portion 22a. . On the other hand, as shown in FIG. 4, the printed circuit board 20 has three mounting holes 2 for each male terminal 22 at the terminal fixing position.
3 is formed, and 3 is formed so as to surround the mounting hole 23 on the back surface side.
Individual lands 24 are formed. These lands 24
A conductor pattern 24a continuously extends to one of the central portions, and electrically connects the male terminal 22 to a circuit (not shown).

防止することができる。According to the above construction, the male terminal 22 is fixed only to the printed circuit board 20, and the upper case 11 is in an unrestrained state by freely penetrating the insertion hole 15 thereof. Therefore, even if the upper case 11 and the printed circuit board 20 undergo thermal expansion due to temperature change and the thermal expansion amounts differ, the male terminal 22 is not.
Does not generate an unnatural stress with the upper case 11 because it is displaced according to the printed circuit board 20. As a result, it is possible to reliably prevent tilt deformation of the male terminal 22 due to thermal stress. Also, since such thermal stress is repeatedly generated,
Although this may cause a solder crack in the soldered portion, according to the present embodiment, thermal stress is not generated in the solder portion, so that the solder crack can be surely prevented.

The connector is pulled out from inside the connector block 13. At the time of mating / unmating of such a connector, a frictional resistance of both terminals may exert a force that twists the male terminal 22. However, in this embodiment, the male terminal 22 branches the three support leg portions 22b into three pieces and is fixed to the printed circuit board 20 so that the male terminal 22 is fixed. Even if a large twisting force acts on 22, it is possible to reliably prevent the male terminal 22 from tilting or wobbling.

効果が得られる。<Second Embodiment> FIG. 7 shows only a difference between the second embodiment of the present invention and the first embodiment, and the structure other than the illustrated portions is the same as that of the first embodiment. . Here, too, the male terminal 30 is the terminal main body 3
The lower part of 1 is provided with three support legs 32. The central support leg portion 32 extends straight downward from the terminal main body portion 31, but the support leg portion 32 located on the left side in the drawing has a crank portion 32 extending in an L shape along the plate surface of the printed circuit board 20.
The support leg 32 located on the right side in the drawing is connected via the L-shaped crank portion 32b in the opposite direction. Therefore, the two support legs 32 on the left and right sides are
The two are sandwiched, and are spaced apart in the direction perpendicular to the plate surface of the terminal main body 31. As a result, even if there is a situation in which the male terminal 30 is prone to fall in a direction perpendicular to the plate surface of the terminal main body 31, the two left and right support leg portions 32 are supported to prevent falling deformation. The effect that it can be surely prevented is obtained.
