Description

[Detailed Description of the Invention] Technology/) Next, the present invention provides a method for layering printed wiring boards on electronic equipment and forming electrical connections between the printed wiring boards or between the printed wiring boards and the equipment. Regarding the connector.

Prior Art Various methods are used to connect printed wiring boards. For example, there is a method of connecting printed wiring boards by using flexible printed wiring boards or flexible wires and soldering them to the printed wiring boards. However, this method not only results in poor work efficiency because the connections are completely connected by soldering, but also has the problem of being difficult to remove once connected, resulting in poor serviceability in terms of maintenance.

Another printed wiring board connection method is to use a plug and socket. This method requires a large insertion force when connecting the plug and socket, and as the number of pins increases, excessive force is applied to the printed wiring, causing defects.

Purpose The first object of the present invention is to push and clamp the printed wiring board to the connector body using a spring plate that also serves as a connection terminal, so that it can be used regardless of the thickness of the printed wiring board, and workability is improved. The object of the present invention is to provide a connector for a printed wiring board that has good serviceability.

A second object of the present invention is to reduce the insertion force required when connecting a printed wiring board by providing a notch in the connector body to facilitate insertion of the printed wiring board between the spring plate and the connector body. This provides a printed wiring board connector that has the same reliability of printed wiring board connection as above.

Blue feeling- Hereinafter, the present invention will be explained in detail with reference to Examples.

FIG. 1 shows a first embodiment, in which 1 is a connector body having a cross-sectional shape, and a printed wiring board 2 is pressed and held between the connector body 1 and the outside of the L-shape. A plurality of conductive spring plates 3 are provided which are connected to the printed wiring board 2 and electricity +rJ. Further, pins 4 electrically connected to each spring plate 3 are implanted inside the L-shape of the connector body 1.

To connect two printed wiring boards with this connector,
One tab 17. is attached to the inside of the L shape of the connector body 1. ．． After engaging the ends of the printed wiring board 5,
and pin 4, and solder the connector body 1.
The other printed wiring board 2 may be inserted and held between the spring plate 3 and the spring plate 3. Spring plate 3
Since the and pins 4 are electrically connected, the corresponding terminals of the printed wiring boards 2 and 5 are electrically connected.

FIG. 2 shows a second embodiment, and when compared with the embodiment shown in FIG. They are different in that they are provided. Notch 6
The cross section of the lower part is formed into an arc shape.

To connect the printed wiring board 2 to the connector of this embodiment, connect the printed wiring board 2 to the connector main body 1 as shown in Figure 5A).
and the spring plate 3, and rotated in the direction of the arrow using the intersection line between the upper edge of the notch 6 and the printed wiring board 2 as a fulcrum, and then clamped as shown in the same figure (B). That's fine. Connect the other printed wiring board 5 to the connector body 1
The steps of engaging the pin 4 and soldering 21 with the pin 4 are the same as in FIG.

According to this embodiment, only a small insertion force is required for the printed wiring board 2, which improves work efficiency and reduces the occurrence of defects in the printed wiring board 2 during insertion.

In FIG. 2, the shape of the lower part of the notch 6 that contacts the end of the printed wiring board 2 is arcuate, which has the advantage that the rotation operation after inserting the printed wiring board 2 can be performed smoothly. The shape of the lower part of the notch may be linear.

Figure 3) shows the third embodiment.Comparing it with the embodiment shown in Figure 1 and Figure 2, we can see that a protrusion 7 is provided as a positioning boss on the spring plate installation side of the connector body l, and that this embodiment The difference is that the printed wiring board 12 which is pressed and clamped to the connector body by the spring plate 3 is provided with a positioning hole 8 at a position corresponding to the positioning boss 7, as shown in the same figure (t3). There is.

In order to hold the printed wiring board 12 in the connector of this embodiment, the printed wiring board 12 is inserted diagonally between the spring plate 3 and the connector body 1 as shown in FIG. 3(B), as in FIG. and then rotate it in the direction of the arrow.
The positioning hub 7 of the connector body 1 may be engaged with the positioning hole 8 of the printed wiring board 12 as shown in q. The connection of the printed wiring board 5 is the same as in FIGS. 1 and 2. FIG. 4 shows a perspective view of the printed wiring boards 12 and 5 connected together. In FIG. 4, reference numeral 9 indicates an electrical component arranged on the printed wiring board 5, and 10 indicates a wiring pattern of the printed wiring board 12.

In general, printed wiring boards are often supported and fixed at both the end where electrical connections are made and the opposite end. In many cases, it is sufficient to simply press and hold the printed wiring board between the connector body 1 and the spring plate 3, but if the printed wiring board is positioned by engaging the positioning boss 7 and the positioning hole 8 as in the embodiment shown in FIG. The fixation of the wiring board becomes even more reliable.

Note that on the above-mentioned power output side, the printed wiring board 5 may be a wire or the like connected to an electronic device.

FIG. 5 shows a fourth embodiment. Cutouts 6,
16 and a positioning boss 7.17, and a spring plate 3.13 is provided on each surface so that both spring brakes 3.13 are made to correspond to each other and are electrically connected. A printed wiring board 12.15 sandwiched between each outer surface of the connector body 11 and each spring plate 3.13 includes a connector body]1
Positioning holes 8, 18 are drilled in the layers corresponding to the positioning bosses 7, 17, respectively.

That is, in this embodiment, the printed wiring boards 12 and 15 are
Both are pressed and clamped using the spring plates of the present invention, and are electrically connected to each other.

Note that 20 is a reinforcing portion for increasing the strength of the connector main body 11.

In this embodiment, both printed wiring boards 12 and 15 may be inserted and fixed by the methods shown in ) and (q) in FIG.

The connector body in the present invention may be molded using an insulating resin that is generally used in molding electronic components or electronic devices. In addition, it is possible to integrally mold the equipment and chassis molded parts, and in that case, there are advantages such as effective use of space for printed wiring boards and cost reduction due to a reduction in the number of parts. be.

Effects As described above, according to the invention of Mizui 1, the printed wiring board is clamped to the connector body by the spring plate and is also electrically connected, so that the printed wiring board can be connected by conventional soldering. Compared to the above method, the workability and maintenance serviceability are the same, and the degree of freedom regarding the thickness of the printed wiring board is also greater.

In addition, according to the invention of Mizui 2, since a notch is provided in the connector body, the force required to insert the printed wiring board is smaller compared to the conventional method of using a plug and socket, which improves work efficiency. This also improves the reliability of printed wiring board connections.
