Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector for electrically connecting units used in electronic equipment, etc., and relates to an improvement in a connector mechanism that makes cable connection a simple connection function.

BACKGROUND ART Conventionally, a large number of connector members have been used to connect internal units of a terminal device, etc., and both ends of a flat cable are connected to the connector members.

A flat cable to which this connector is connected is arranged along the panel surface inside the device, and the connector is connected to the connector of each unit.

For example, as shown in FIG. 1, such a connector connects each unit by connecting a male connector 2 provided on a printed board unit 1 and a female connector 4 to which a corresponding flat cable 3 is connected. Ru.

Conventionally, the method of connecting the cable 3 to the opposing female connector 4 involves soldering, wrapping, etc. the wire core of the cable 3 to the numerous contact terminals 7 of the female connector 4 shown in FIG. 1, which requires a lot of effort. ).

Therefore, the crimp connection method, which is a simple connection method, has come to be used.

However, in this method, the shapes of the connector terminals 7 vary depending on the type of the connector 4, and the crimp connection is performed using a special tool for each type of connector, which makes the tool expensive. There is a drawback that the work efficiency is hindered because many types of tools are used.

Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks, and to provide a connector mechanism that provides a simple connection function to a contact member. In the connector mechanism, at least one of the connectors is provided with a wave-shaped elastic contact member consisting of a contact portion and a cable connection portion, and by pressing down and inverting the contact member, the cable connection portion is connected to the cable connection portion. This is realized by press-welding.

An embodiment of the connector mechanism according to the present invention is shown below with a perspective view of a female connector in FIG. 2 and a line A-A' in FIGS.
This will be explained using a cross-sectional view taken in the direction of arrows.

As shown in the figure, the connector mechanism of the present invention is a connector that has a connection function when crimping and connecting a plurality of cables to the contact terminals of a female connector, and can be connected using a simple tool.

In the connector mechanism of the present invention, as shown in FIG. 2, a plurality of insertion holes 8, corresponding connection window holes 9, and confirmation window holes 10 are molded into a female connector 4.

Further, as shown in FIG. 3, the contact member inserted into the insertion hole 8 of the female connector 4 waves the integral plate spring 14 having the wire connecting portion 12 on the left contact portion 11 and the stopper 13 on the right side. Form into shape.

These components are integrated.

In such a connector mechanism of the present invention, FIG.
As shown in Figure 2, insert the cable 1 from the right side into the insertion hole 8 of the female connector 4, where the leaf spring 14 of the contact member is arranged, up to the hole 9 of the connection window, and insert the push member shown in Figure 2 through the hole 9 of the connection window. Insert a tool 15 such as a screwdriver into the confirmation window hole 10 and press down until the stopper 13 appears as shown in the figure.

Then, when the wave shape of the leaf spring 14 passes the neutral point, the leaf spring deforms and reverses the wave shape as shown in FIG. The wire connecting portion 12 is connected by pressing the tip of the cable 1 as shown in the figure, and the stopper 13 engages with the side surface of the hole 10 of the confirmation window to hold the contact member of the leaf spring 14.

Therefore, the connector mechanism allows the cable 1 to be connected to the contact terminal 7 of the female connector 4 by the tool 15.
Since the wire connecting portion 12 can be connected by pressing the cable 1 using the pushing blade of the pushing member and the reversal force of the urging of the wave-shaped leaf spring 14, the pushing member can be used with a tool such as a simple screwdriver. This can be done by

In addition, as another embodiment, the pushing member such as a simple driver may be formed by integrally molding the pushing member into the main body of the connector 4.
It is also possible to have a simple push-down member.

As explained above with reference to the embodiments, according to the connector mechanism according to the present invention, the cable is pressed into contact with the contact member by the reversal force of the biasing force of the wave-shaped plate spring and by pressing the push member with a simple tool. Cables can be connected using the wire connection section that converts into multiple contact terminals on the female connector.
There are advantages such as no need for conventional special tools and ease of operation.
