No. 02046. Such pins, also known as compression compliant pins, are mounted in through holes in printed wiring boards. The holes are generally made of copper and are provided with a metallization, with a tin layer of tin covering it. In such an electrical connection between the pin and the metallization, a solderless or similar connection is required anyway, but the electrical contact is obtained by a closed form fit and a frictional connection.

Is pushed out or pushed out. In the case of the pin known from the aforementioned Dutch specification, the purpose is to allow the four fins of the insertion part of the pin into the hole of the printed wiring board to be gradually bent inwardly, thereby causing four points in the hole. The fixation of is obtained. The H-shaped design reduces or eliminates the risk of rotating pins during mounting. Often, square pins of that kind, widely used in the printed wiring board industry in the above conditions, can be used. The plurality of protruding fins are completely symmetrically configured,
It is very important that all four have the same thickness so that when inserted into the hole all four bend and bit into the metallization of the hole. Therefore, the slightly different thickness and hence the different hardness of the protruding fins leads to a rotational or eccentric position of the pin obtained during insertion, which causes serious damage to the metallization of the hole. . It is also weakened by a counter plug on the opposite side of the printed wiring board, which fact causes the rotated square pin to have a sharp biting face with the fixed counter plug.

Has a shape. A vertical recess with a V-shaped bottom is obtained by means of a corresponding knife-shaped die. During stamping of the longitudinal recess, this V-shaped bottom acts as a central facilitator, which results in a perfectly symmetrical design of the fins on either side of the recess with the same thickness and height. .

For example, it is larger than the requirement of m. The changes that exist at the fin height in the well-known contact pin from a straight point to the contact, where the change is bent slightly inward, are practically inappropriate to prevent such deformation. I understood.

Two fins are shown at 3 and 4, and the gradual increasing and decreasing transitions of these fins at the insertion side and opposite side of the contact pin during the manufacturing stage are shown at 7 and 8, respectively. Figure 1 (b)

It can be clearly seen from the beginning that the contact surface between the pin and the hole is initially small. Figure 2 (b) gives a cross-sectional view of the further inserted contact pin along the Id-Id line of Figure 1 (b), how the fins are in a uniform and symmetrical form. It can be clearly seen from this that it is bent slightly inward, resulting in contact of the holes with the metallization. The H shape of the contact portion is almost maintained. It is clear that this slight bending caused by insertion during mounting is still not present at the gradual transitions 7 and 8.

FIG. 3 (b) shows a vertical cross section running along the vertical axis. 3C, 3D, and 3E show contact pins of FIG. 4A along the line IIIc-IIIc, the line IIId-IIId, and the line IIIe-IIIe of FIG. 4A, respectively. A cross-sectional view is shown. It can now be seen that the fins are bent inward over a considerable part of the longitudinal distance of the contact, increasing gradually first and then decreasing. At the same time, (c) of FIG.
As can be seen from the comparison between (d) and (e), the height of the fin increases from the beginning to the maximum value as the number of lateral ribs decreases. A significant portion of the above can be about half the vertical distance. A softer insertion of the contact pin into the printed wiring board hole is obtained by the inward curvature of the fin, which is strongest, especially in the section between the cross sections IIIc-IIIc and IIId-IIId. For example, the stringent requirements of the MIL standard can be met by this design.

FIG. 4B shows a cross-sectional view of the further inserted contact pin along the line IIIe-IIIe in FIG. 3B. The intermeshed enlarged contact between the fins and the metallization of the holes can also be revealed from the latter cross-section.

It is shown that the two bushes 11 and 12 are symmetrically located above and below the pin contact portion, respectively. The two bushes in the first example are not shown to each consist of a straight half cylinder. In another example, each semi-circular bush is composed of a first semi-circular section 13, a semi-conical section 14 and a second semi-circular section 15. The two bushes are located opposite each other and symmetrically opposite each other, and the parts 13, 1
The transition between the 4 and the oppositely arranged is IIIc in FIG. 3 (b).
From the IIIc cross section, the transverse rib 10 is deformed to rest on the transverse plane of the contact where the decreasing thickness is constant, and the counter-arranged transition between the parts 14, 15 is its longitudinal distance. Around the contact pin for placement on the transverse plane of about half the contact along the. In the example, first
The diameter of the cylindrical portion is 0.62 mm, the angle of the conical portion is 11 °, and the diameter of the second cylindrical portion is 0.85 mm.

好な接触が保証される。The pressing action of the two semi-cylindrical bushes that surround and oppose the contact pin can be seen better on the top side of the pin in FIG. 3 (a) and on one side of the pin in FIG. 4 (a). Results in four protruding fins that are bent inward. As can be seen from (c), (d), and (e) of FIG. 3, the H-shape of the contact portion approaches the double C-shape. Through this deformation, a better and softer insertion into the printed wiring board hole is obtained with a lower pressing pressure. This results in less deformation of the hole metallization and maintaining the pin attitude (eg non-rotating), which ensures good contact with the counter plug.
