Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a pin header, and more particularly to a pin header for connecting a female connector to, for example, a printed circuit board.

BACKGROUND OF THE INVENTION Female connectors and pin headers are used to electrically connect electronic devices and other electrical devices, such as printed circuit boards. Lead wires of the electronic device are electrically connected to the female connector, while each of the pins of the pin header are electrically connected to a plurality of contacts on the printed circuit board, and the female connector and the pin header are mechanically coupled, thus The electronic device and the printed circuit board are electrically connected.

There are various forms of pin headers,
An example of this is shown in FIG.
That is, a main body 1 consisting of a bottom part 2 and a side part 3 and having a substantially L-shaped cross section, and a plurality of pins penetrating the bottom part 2 of the main body and provided in a row substantially parallel to the side part 3. It consists of 4. The body 1 is made of an electrically insulating material, for example nylon, and the pin 4 is made of an electrically conductive material, for example brass. A female connector having contact holes that fit each of the plurality of pins 4 is fitted from above, and its bottom surface abuts the top surface of the bottom portion 2 of the main body 1. The side portion 2 functions as a support portion for the connector to be fitted and provides a stable connection between the two. A bulge 5 is provided at the top of the side part 2 to provide more stable support.

The conventional method for manufacturing a pin header such as that shown in FIG. 1 has been to first mold the body 1 by injection molding or the like, and then insert the pin 4 into the body. This method requires two steps: molding and pin insertion, so the production efficiency is relatively low. Therefore, for example, a pin is installed at a predetermined position in a mold and the body material is injected into the mold. It has been desired to improve production efficiency by such a method.

Problems to be Solved by the Invention However, in the pin header of the form shown in Fig. 1, after the main body material is injected into a split mold in which a plurality of pins are placed at predetermined positions and molded,
It was almost impossible to open the split mold without deforming the body or pin.

The purpose of this invention is to solve the above-mentioned conventional problems and provide a pin header that has the same performance as conventional pin headers but can be manufactured in one step using a split mold. It is to be.

Means for Solving the Problems According to the present invention, the above-mentioned problems are solved by a main body formed of a plastic material having a bottom part and a side part and having an approximately L-shaped cross section, and a main body formed of a plastic material having a substantially L-shaped cross section. A pin header consisting of a plurality of conductive pins, characterized in that the side portions of the main body have a gap that allows a projected image of the pins to pass through when the pins are projected perpendicularly to the bottom side. This problem can be solved by using a pin header.

Embodiment Next, a preferred embodiment of the present invention will be described with reference to FIGS. 2 to 4.

Fig. 2 is a perspective view of the pin header, Fig. 3 is a horizontal sectional view at approximately the vertical center of the pin header shown in Fig. 2, and Fig. 4 is a horizontal sectional view of the split mold in the closed position. It is a diagram.

A plurality of pins 14, 14, . . . are installed approximately at the center of the bottom portion 12 of the main body 11 in the width direction, passing through the bottom portion in a substantially straight line. The difference from the pin header shown in Figure 1 is that the side part is divided into a plurality of pieces 13', 13'', 13... As seen in Figure 2, the divided parts Each of the pieces 13', 13'', 13... is located between two adjacent pins 14, and their width is smaller than the spacing between adjacent pins. In other words, between pieces 13', 13'', between 13'', 13...
The gap is positioned and sized to allow passage of a projected image of the pin 14 when projected perpendicularly to the side portion. This is most clearly shown in FIG. In addition, 15', 15'', 15
... indicates a bulge corresponding to bulge 5 in FIG.

Such a pin header can be manufactured by the method described below.

As shown in FIG. 4, by moving the split molds A and B in the direction of arrow X and closing them, the main body 11
A cavity of a predetermined shape is formed for the purpose, and the pins 14, 14, 14, . . . are positioned at predetermined positions. Next, the main body 11 is molded by injecting a plastic material into the cavity, and the pins 14, 14, 14, . . . are fixed while passing through the bottom portion 12 of the molded main body. When the split molds A and B are opened in the direction of arrow Y in FIG. 4 after molding, as is clear from the figure, the movement of the split molds A and B is not hindered by the main body or the pin. In this way, by providing a predetermined gap on the side of the main body, it became possible to manufacture a pin header with a pin penetrating the bottom of the main body in one step using a split mold. be.

In FIG. 2, 16 is the contact surface of the female connector, and the upper surface 1 of the part through which the pin 14 passes.
7 is one step lower than the contact surface 16. The plastic material may bulge slightly around the pin during molding, but since surface 17 is lower than surface 16, this bulge will prevent the female connector from abutting against surface 16. You won't be disappointed. For the same purpose, the lower surface of the bottom portion 12 is also formed in a stepped shape.

In the example shown in FIGS. 2 to 4, adjacent pins 14,
14 in all the gaps between the side parts 13',
13'', 13, . . . However, a portion of the dividing piece (for example, 13'') may be omitted as long as the dividing piece as a whole serves as a support for the female connector. In the illustrated example, the pins 14, 14, 14, . . . are arranged in a line on the same plane, but if necessary, they may be arranged in a zigzag pattern, for example.
Further, in the embodiment, the spacing between adjacent divided pieces is larger than the projected width of the pin, but it may be narrowed until it becomes approximately equal to the projected width of the pin.

Effects of the invention According to the invention, since the side portion of the main body has a gap of a predetermined position and size, the split mold can be opened and closed through this gap, and therefore, such a split mold can be opened and closed. Using this method, it is possible to manufacture a pin header in which a plurality of pins pass through the main body in one step. Thus, the pin header of the present invention has the same functions as conventional pin headers, but can be manufactured much more efficiently than conventional pin headers.
