として圧入方法がある。(Prior art and its problems) A soldering method that is widely used to connect electrical wires coated with insulation such as vinyl to contacts of connectors, etc., that is, it does not strip the electrical wire coating or cause excess or deficiency of solder. In place of the soldering method, which requires a certain amount of solder to be measured and requires complicated and sophisticated techniques such as controlling the soldering temperature and soldering time, a so-called solderless connection method that does not use solder has recently been introduced. One method that has been developed and widely used is the press-fit method.

単に接続できる利点がある。 This method is similar to other solderless methods, such as the so-called wire wrapping method in which the core wire of the wire is wrapped around the contact tail, and the crimping method in which the connecting piece provided on the contact tail is bent onto the wire so as to wrap the core wire of the wire. Another advantage is that solid wires or tape wires can be easily connected by simply press-fitting them into the slit, without the hassle of stripping or wrapping the wire, and without the risk of poor connections due to insufficient crimping. be.

から実現が難しい。 On the other hand, in the press-fitting method, in order to reliably tear the coating of the wire until it reaches the core wire and hold the core wire under pressure, as described above in Fig. 1, it is necessary to
Unless both sides 3b of the slit 3a have sufficient mechanical strength to be difficult to be pushed open left and right by the electric wire 2 and have sufficient spring force to pinch the core wire 2a from both the left and right sides, a reliable connection can be expected. Can not. For this reason, in conventional products that have a press-fit connection part integrated with the contact tail, the quality of the connection is almost determined by the material and thickness of the contact material. It is necessary to change the thickness of the part. However, this method is difficult to achieve in practice due to manufacturing and cost constraints.

When the contact and the press-fit connection are integrally formed, it is difficult to ensure reliable contact between the press-fitted electric wire and the spring metal layer 4b that provides electrical conductivity. It is difficult to find a method.

(Summary of the Invention) The present invention provides that an intermediate connector having an insulated wire press-fit connection at one end is made separately from the contacts of the connector, that is, is made as a separate member, and an electric wire provided at the other end of the connector is provided in the middle. The connection part with the connector is connected to the connection part provided on the contact side of the electrical connector by, for example, a plug-in spring contact. It also prevents the press-fit connection from being influenced by the material of the contact and ensures a reliable connection, and also ensures that wires can be connected reliably even in the case of a connector with contacts made of the three-layered material. This is what I did.

On the other hand, as shown in the cross-sectional view of FIG.
A connector 7 is formed by fixing the contact 1 provided with the inside of an insulating housing 7b. Then, as shown in the front view of FIG. An electric wire is connected to the contact 1 by bringing the spring connecting portion 1b provided on the contact tail 1a of the connector into contact with the portion 5. Furthermore, when inserted into the insertion hole 7a, the connection portion 5 of the intermediate contact 6 is brought into contact with the surface of the insertion hole 7a by the connection portion 1b, which is short in length and is provided on the contact tail 1a and which applies an extremely strong spring force. The intermediate contact 6 is housed and fixed in the connector by being strongly pressed against it so that it does not come off from the connector. Note that as a means for accommodating and fixing the intermediate contact so that it does not come out from inside the connector, the means described later with reference to FIG. 9 may be employed.
