Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a bandolier pin for a connector in which a large number of connector pins for electrical components are temporarily fixed to a metal strip plate across the width direction of the strip plate.

<Prior art> As shown in FIGS. 4 to 6, conventional bandolier pins are placed at the same position on both left and right edges of a flat strip plate 2.
A large number of concave-shaped pieces 3 are vertically arranged at predetermined intervals in the front-rear direction, and one connector pin 1 is inserted into a vertical cut groove 3a opened on the upper surface of the concave-shaped pieces 3, 3 at the same position on both left and right edges. Insert the destination, position it,
The free end portion of the cut and raised piece 4, which was formed by punching out the strip plate in a U-shape in the longitudinal direction, was temporarily fixed by hanging it over the upper surface of the central portion 1a of the connector pin 1.

<Problem to be solved by the invention> Since the bottoms 3a' of the vertical cut grooves 3a of the concave shaped plates 3, 3 installed upright on the left and right side edges of the strips are upwardly separated from the upper surface of the strips, the bottoms 3a' The pin 1 supported by ', 3a' floats on the strip. Since the length of the cut-and-raised piece 4 is limited by the fixed interval of the pin 1 in the front-back direction, conventionally the free end 4' of the cut-and-raised piece 4 can barely reach the pin as shown in FIG. The pins were only able to hold down the top surface, and the pins sometimes fell off the strip before being attached to the electrical components.

<Means for solving the problem> Therefore, the bandolier pin for connectors of the present invention has a large number of protruding pieces vertically arranged in pairs at the same position on both left and right edges of a flat strip plate. Place one connector pin in the space between the front and rear protruding pieces at the same position on both left and right edges, place it on the upper surface of the strip, and punch out the strip in a U-shape in the longitudinal direction. The free end of the cut and raised piece was wrapped around the top surface of the connector pin to cover most of the top surface, and the connector pin was held by a pair of front and rear protruding pieces on each side edge of the strip plate. It is characterized by

<Example> In each example shown in Figs. 1 to 3, 11 is a pin (or a wire material before being finished into a pin), 12 is a strip plate, 1
3 is a pair of protruding pieces vertically placed on the left and right edges of the strip plate, and 14 is a cut-and-raised piece made by punching out the central part of the strip plate in a U-shape in the longitudinal direction. show.

The distance 13a between the front and rear protruding pieces 13 is the same as the band plate 1.
2, the distance 13a between the front and rear protruding pieces 13 located at the same position on the left and right side edges.
The pin 11 passed through is received on the upper surface of the strip plate 12. Therefore, even if the length of the cut and raised piece 14 is the same as that of the conventional example, most of the upper surface can be covered by wrapping the free end portion around the upper surface as shown in the figure. Note that the upper surface refers to the upper surface obtained by dividing the circumferential surface of the pin into four equal parts, vertically, horizontally, and horizontally.

In the embodiments of FIGS. 1 and 3, the pin 11
is inserted into the space 13a between the front and rear protruding pieces 13, and then using the processing tool T and the abutment tool T' indicated by chain lines, support the lower surface of the strip plate 12 with the abutment tool T', and press the pressure tool T. Push the pair of protruding pieces 13 toward each other diagonally from above, plastically bending only the protruding pieces 13 without bending the strip plate 12, reducing the gap 13a by about 0.02 mm from the pin thickness, and then inserting the pin 11 into the pair. protruding piece 1
3 so that it can be held elastically. In this case, in order to reduce the amount of plastic curvature of the protruding pieces 13 and avoid unnecessary deformation, it is preferable that the distance 13a between the pair of protruding pieces is set close to the thickness of the pin 11.

Further, in the embodiment of FIG. 2, the distance between the pair of protrusions is 13
The upper part of a is narrower than the thickness of the pin 11, and the lower part is slightly wider than the thickness of the pin, so that the pin 11 can be held in the mouth from the beginning. The upper part of the gap 13a is narrow enough to allow the pin to pass through it depending on the elasticity of the material of the strip, for example, when the pin 11 has a thickness of 0.6 mm.
Set to 0.55mm.

<Effects of the invention> As is clear from the above, according to the invention, the free end of a cut-and-raised piece of the conventional length punched out from a strip is wrapped around most of the upper surface of the pin. In order to restrain the pin on the strip and hold the pin with a pair of protruding pieces that form an interval for passing the pin onto the upper surface of the strip, the pin falls off the strip before attaching the connector pin to the electrical component. This can be reliably prevented.
