Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a groove structure for accommodating connector terminals.

Conventionally, many connectors for printed circuit boards, for example, have a structure in which a fixed mold is provided with a groove, and terminals are accommodated in the groove to provide the function of a male connector. FIG. 1 shows a perspective view of a typical connector structure. Terminal molds 3 and 3' having a plurality of terminal parts 2, which are connecting conductors, are connected from both sides (top and bottom) of a fixed mold 1 with, for example, rivets 4. It is fixed and assembled into the fixed mold 1. At this time, the contact portion 2' with the female connector to be paired is accommodated in the groove 7 of the fixed mold 1. The connector shown in FIG. 1 is attached to a printed board through a mounting hole 5, and the connection terminals 6, 6' are soldered to the through holes or connection pads on the printed board. As a male connector, it fits into a female connector on a large backboard, for example.

In this connector, the terminal mold 3 has the shape shown in FIG. is formed by press working or the like. During this manufacturing process, the contact portion 2' swings in the direction of arrow A in Figure 2 due to various manufacturing deviations, so the width of the groove 7 is formed to be larger than the width of the terminal portion 2 to absorb the swing. , terminal part 2 to groove 7
The improvement of the upsetting performance is considered. In this case, groove 7
Due to the gap between the inner wall of the housing groove 7 and the terminal part 2, in the conventional completely rectangular groove 7 as shown in FIG. There is.

Therefore, if this deflection is large, the spring part 11 of the female connector may not come into contact with the contact part 2' in a connector with a small contact part width such as one intended for compactness and high density, which may reduce the reliability of the connector. There was a risk of a significant decrease in

An object of the present invention is to eliminate such drawbacks and provide a highly reliable connector terminal accommodating groove structure suitable for compactness and high density.

The present invention is characterized in that a protrusion is provided on the side surface of the groove to restrict the contact portion of the terminal from being accommodated in the center of the groove in order to prevent the contact portion from lateral movement within the terminal receiving groove as described above. . The present invention will be explained in detail below with reference to an embodiment shown in the drawings. FIG. 4 is a cutaway perspective view of a groove showing an embodiment of the present invention. That is, in the present invention, the inner wall 8 of the groove 7 is provided with a protrusion 9 having a substantially semicircular cross section. Further, an oblique portion 10 is provided on the upper part of the protrusion 9, and the terminal mold 3,
The structure is such that the contact portion 2' can easily enter the groove 7 when the contact portion 3' is assembled. Although not shown in FIG. 4, it goes without saying that the inner wall on the opposite side also has a similar protrusion. The inner dimension determined by the pair of protrusions 9 approximately matches the width of the contact portion.

According to the present invention, as shown in the cross-sectional view of FIG. 5, the contact portion 2' can be fixed to a predetermined portion of the housing groove 7, and the contact reliability with the spring portion 11 of the female connector is sufficiently ensured. I can do it.

There are no particular technical problems with the present invention, and the purpose can be achieved by simply adding a protrusion. Furthermore, since the width of the contact portion can be made smaller, there are significant cost effects such as reduction in metal plating costs, and it is possible to realize a highly reliable connector that is compact and suitable for high-density mounting extremely easily and inexpensively.

In the above embodiment, the terminal mold 3 has been described as being assembled from both sides, but it goes without saying that the present invention can also be applied to a structure in which the terminal mold 3 is assembled from only one side.
