とがある。One of the necessities of the above-mentioned plug-in type connector is to recognize whether or not the connection by inserting the wire connection end into the holder is securely performed. May be configured to be able to perform the determination.

る。[0004] That is, if the insertion of the electric wire into the connector is insufficient, not only the required reliability of the connection between the electric wires is impaired, but also poor contact tends to occur.
The resulting heat may cause a fire accident.

できるようにしたもの等が既に提案されている。[0005] For this reason, in order to prevent such mistakes in insertion of the electric wire, an electric wire insertion identification piece which can be swung by insertion of the electric wire is provided in a part of the holder of the connector so that the movement of the identification piece can be prevented. There have already been proposed ones that can be grasped visually or by tactile sensation.

ことが望まれる。However, forming such an electric wire insertion identification piece and a window for confirmation from outside thereof integrally with the holder or the like tends to complicate the molding die of the holder,
It is costly and it is desirable to take some measures.

必要とされている。[0007] Further, as a problem in configuring such a plug-in connector, there is a contact structure including a conductive plate and a leaf spring incorporated in a holder. In other words, such a contact can be easily and surely connected to the wire peeling portions inserted into the contact, and the wire press-connecting function can be maintained with high reliability for a long time. Is required.

い。That is, conventionally, as such a contact, a contact formed of a conductive plate made of a copper material or the like and a leaf spring having a spring piece for pressing an electric wire peeling portion against the conductive plate is used. However, with the conventional contacts, not only is the structure simple and easy to assemble, but also the ease of insertion of the wire stripping part to be inserted, the reliability of electrical connection by securing the contact area and contact pressure, and the Nothing has been proposed yet that can both prevent the detached portion from coming off.

固定したものが多い。In particular, when fixing the base end of the leaf spring to the conductive plate, a plurality of electric wire insertion holes are formed in one plate portion of the conductive plate bent and formed to have an L-shape, for example. A crimping piece is provided on the outer edge, and a protrusion provided on a part of the piece is crimped through a hole formed on the leaf spring side, and the base end of the leaf spring is crimped to the conductive plate and fixed. There are many things.

として電気的導電性が劣化してしまう。However, in such a contact made of a conductive plate and a leaf spring by crimping, an electric wire is inserted into a wire insertion hole of the conductive plate, and a leaf spring is pressed against the insertion end side of the electric wire and the tip end is pressed. When a force is applied to the wire receiving portion of the conductive plate and the tip of the leaf spring in a direction in which the wire spring extends, when this force is applied, the force is applied to the portion of the conductive plate having the wire insertion hole or the leaf spring. Is applied to the part as a deformation force, the part of the conductive plate with the wire insertion hole and the swaged part is deformed in the direction that the tip of the leaf spring separates from the wire and reduces the pressure contact force, resulting in deterioration of electrical conductivity. Would.

を図ることができないという問題もあった。Further, in the conventional contact, depending on a fixed state by caulking, the tip end of the leaf spring is easily lifted up with respect to the conductive plate, and a gap between the leaf spring and the wire receiving portion of the conductive plate is formed by an electric wire. Therefore, there is also a problem that even if the electric wire is inserted, the leaf spring is cut into the electric wire so that it cannot be prevented from coming off.

らない。The angle between the leaf spring fixed to the conductive plate and the conductive plate at the distal end side is as follows:
This is important in ensuring the ease of insertion and prevention of wire insertion. That is, if the angle between the conductive plate and the spring piece forming the contact is set to be small in consideration of the insertability of the wire and the reliability of the electrical connection, the function of the spring piece to prevent the wire from coming off is impaired. On the other hand, if the above-mentioned angle is set to a large value so that the spring piece bites into the electric wire and this slippage can be reliably prevented, the gap between the conductive plate and the spring piece constituting the contact of the electric wire is increased. Insertion becomes difficult, and the contact area cannot be ensured, and the electrical connection performance is impaired. Such points must be considered.

By using a synthetic resin material, it is possible to extremely easily construct a contact that can make electrical connection of the wire peeling part by press-fitting connection, and it is also possible to confirm and check the insertion state of the wire easily and reliably. The purpose is to get.
