After the upper molds of the split molds are combined, the softened and melted insulating synthetic resin is injection-pressed into the internal space of the combined molds. Thereafter, the mold is divided when the softened and melted insulating synthetic resin cools and hardens. Then
A connector having a terminal housing integrated structure in which the terminal and the housing are integrated is completed, and the connector can be taken out.

Then, when the fine debris is caught between one terminal and the terminal on the other side when the connectors are connected to each other, it causes electrical contact failure. However, the burr A is not small,
There is a problem that the electrical contact failure caused by the burr A has not been completely eliminated.

る。In FIG. 1, reference numeral 1 denotes a thin plate-shaped conductive metal terminal. The terminal 1 protrudes from the inside of the housing 2 made of insulating synthetic resin. The housing 2 is formed by a split mold composed of an upper mold B and a lower mold C that bisects in the vertical direction as shown in FIG. 2, and a mold dividing line L as shown in FIG. At the same time, a step δ is formed on the mold dividing line surface. The step δ is dimensioned so that the burr A does not protrude outside the outer shape of the housing 2.

触不良を引き起こすことはなくなる。In the terminal housing integrated structure manufactured as described above, for example, in a connector, the terminal 1 is not connected to the inside of the housing 2 due to the minute clearance between the terminal groove C 1 of the mold and the terminal 1. Even when burrs A are generated at the portions protruding from the burrs, no external force acts on the burrs A due to the presence of the step δ. That is, the burr A does not collapse due to an external force, and no fine dust of insulating synthetic resin is generated. Therefore, unlike the related art, the fine dust generated by the collapse of the burr A does not become caught between one terminal and the terminal on the other side when the connectors are connected to each other, thereby causing poor electrical contact. .

The terminal 1 has a terminal base 1 inside the housing 2 rather than a terminal protrusion 1 a outside the housing 2.
By making b wider, and making the wider front end of the terminal base 1b close to the inner surface of the mold, the flow of the insulating synthetic resin near the terminal protrusion during molding is suppressed.

性合成樹脂の流動を抑制するようにしている。In FIG. 4, reference numeral 1 denotes a thin plate-shaped conductive metal terminal. The terminal 1 protrudes from the inside of the housing 2 made of insulating synthetic resin. The housing 2 is formed by a split mold including an upper mold and a lower mold as in the first embodiment described above, and a mold split line L as shown in FIG. At the same time, there is a step δ on the mold dividing line surface. The terminal 1 is connected to the second

Even if the insulating synthetic resin that has been softened and melted is injection-pressed,
When the softened and melted insulating synthetic resin reaches the vicinity of the minute clearance between the terminal groove of the mold and the terminal 1, there is no flow force.

The generation of the burr A itself can be suppressed. And, by any chance,
Even if burrs A are generated, there is a step δ on the mold dividing line surface, so that the burrs A do not collapse due to an external force, and no fine dust of insulating synthetic resin is generated. Therefore, it can be said that the fine dust generated by the collapse of the burr A is not caught between one terminal and the terminal on the other side when the connectors are connected to each other, thereby causing poor electrical contact. It is not enough.

ハウジング一体化構造。2. A terminal housing integrated structure in which a housing made of an insulating synthetic resin is integrally molded with a terminal for making an electrical connection with the outside with a split mold, and a terminal protruding portion outside the housing is located within the housing. A terminal characterized in that the terminal base is made wider so as to suppress the flow of the insulating synthetic resin near the terminal protrusion during molding, thereby suppressing the occurrence of burrs from near the terminal protrusion of the housing. Housing integrated structure.
