Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an electrical connector used in various electronic devices.

<Prior Art> Conventionally, various cables have been used to connect various electronic devices.

Pin-and-socket type connections are used for connections between cables of this type and electronic equipment.

That is, on the cable side, some kind of pin is attached to the end of the cable, and on the other hand, on the electronic equipment side, a socket for receiving this pin is attached.

Flexible printed cables are commonly used as cables that do not require the transmission of power and simply transmit electrical signals.
Alternatively, in cases involving the transmission of a small amount of current, so-called flat cables are used in which the necessary number of organic coated wires are laid flat and integrated by mutual fusion of the coated wires or other methods. Connections to sockets are not possible and some type of connector must be attached to their ends.

It is an object of the invention to provide such a connector.

Means for Solving the Problems> According to the present invention, there is provided a connector comprising a fixing member made of an insulating material and a plurality of flat conductive members running orthogonally to the fixing member.

The flat conductive material has at least one end flat and can be electrically connected to a cable or the like by soldering or other methods,
On the other hand, the other end that contacts the mating socket 1- is deformed,
It is made to have a slight thickness to avoid wear and the like, and is made integral with the fixing member on one side to prevent deformation due to interaction with the contact portion of the mating socket.

Preferably, a support made of the above-mentioned insulator is provided.

<Function> It is clear from the following explanation that by preparing such a connector, connectors for various electronic devices can be prepared extremely easily, and also can be attached to various electronic devices extremely easily. Become.

<Embodiments> Hereinafter, preferred embodiments will be described with reference to the drawings, and examples of various electronic devices using such connectors will be described.

FIG. 1 is a top view of the connector according to the present invention. In the figure, 1 indicates an insulating fixing member, and 2 indicates an insulating support on which a conductive member 3 is placed, preferably It is made of the same material as the fixing member 1 and formed by a molding method or the like.

Reference numeral 3 denotes a conductive member, which is formed from a flat metal strip whose central part passes through the inside of the fixing member 1. For manufacturing reasons, one metal thin plate is shown as a dotted line in the figure. It is preferable that the dummy portion 4 be formed integrally with the dummy portion 4 by, for example, press processing, molded with an insulating material such as plastic, and then cut off along the broken line 5-5.

This plastic material forms the fixing member or support.

The lengths of the conductive members 3 supported in this manner do not necessarily need to be equal on the support body.In electronic equipment, it is not necessarily desirable to apply signals or voltages to each terminal at the same time, and it is difficult to connect. This is because there are cases where it is preferable to have a slow speed.

One side 3a of the conductive member 3 is normally connected to a cable or the like, but it is preferable to solder it to make the connection easier.

Going back a little bit, the conductor 3b on the support is, for example, a connection terminal (not shown) shown at 24 in FIG. ).

Therefore, when such a connector is used for an item such as an IC card that is frequently inserted and removed from a socket, it is desirable to select a material that is wear-resistant and highly conductive.

Furthermore, as shown in Fig. 2, it has been stated that a flat plate is used as the conductive member, but if there is a possibility that a considerable force is applied to the terminal 3b and the terminal 3b is pulled out from the fixing member, the conductive member shown in Fig. 3 is used. As shown, the conductive material may have flat portions 3a, 3b and a vertical portion 3c connecting these in the fixing member.

Finally, as mentioned above, considering the terminal 3b in the conductive member, this terminal 3b exerts a considerable force with the socket pin, and this force causes the terminal 3b to It is extremely undesirable that damage and deformation may occur, resulting in accidents such as short circuits.

In order to avoid such an accident, it goes without saying that consideration should be given to the dimensions of the conductive material, but in addition, in the present invention, as shown in FIGS. 4 and 5. support 2
A groove 6 is provided on one surface, and the terminal 3b is housed in the groove, so that only the surface of the terminal 3b can be made slightly higher or lower than the surface of the support 2, as shown particularly clearly in FIG. good.

By doing this, there is no possibility of lateral movement of the terminals 3b, and hence of short circuit between the terminals.

Next, some examples of applications of such connectors will be explained.

FIG. 6 shows an example in which the connector according to the present invention is applied to a so-called flexible printed cable.

In the figure, 7 indicates a printed cable, 8 indicates a printed circuit portion, and 9 indicates a flexible substrate.

Note that if there is an insulating coating on the printed circuit 8, the coating is removed in advance from the portion that contacts the leads 3a of the connector.

Next, a connector having a conductive member pitch made equal to the pitch of the printed circuits of this cable is installed on the cable so that the printed circuits and the conductive members face each other.

The printed circuit 8 and the conductive member 3a are connected, for example, by soldering or the like.

In this way, a flexible printed cable with a connector can be prepared.

FIG. 7 shows an example in which such a connector is applied to an IC card described in the above-mentioned application filed by the present applicant.

Since the connection terminals of IC cards are made using printed circuit technology, their thickness is not very thick.

Therefore, there is a possibility that the card may become unusable due to wear due to insertion and removal from the socket due to deformation, but in order to avoid such troubles, a connector is attached to the IC card as shown in FIG. 7.

The mounting method is the same as in the case of FIG. 6, and is carried out by soldering, but the only difference from the previous embodiment is that since the terminals are exposed, there is no need to remove the upper covering.

The last embodiment shown is an example in which the connector of the present invention is attached to a flat cable.

This is shown in Figure 8a.

This type of flat cable uses a single-core insulated wire,
This cable has a plurality of electric wires running in parallel in one plane, which are fused to each other at the insulated parts of the cable, and a cross section perpendicular to the running direction of the electric wires is shown in FIG. 8b.

First, the insulation coating at the end of the cable where the connector is to be attached is removed to expose the wire.

Next, connectors having a pitch equal to the pinch of the electric wires of the cable are prepared, and the conductive members 3b of the connectors are superimposed on the electric wires and then fixed to each other by, for example, soldering, thereby attaching the connectors.

<Effects of the Invention> In this manner, it should be noted that the connector of the present invention is extremely easy to manufacture and can be easily attached to various electronic devices, and has an extremely wide range of applications.
