を目的とする。However, in the conventional pressure contact connector, in order to form the bent portion 31, the tension absorbing plate 27d must be formed on the pressure contact terminal 27,
As a result, the total length of the expanded shape of the pressure contact terminal 27 becomes extremely long, the amount of material used increases, and the pressure contact terminal 27 becomes expensive. In particular, since the press contact terminal 27 is a component which is used most per one press contact connector, it causes a significant cost increase. Also, the tension absorbing plate 27d
In order to form the plate from a flat plate, a complicated bending process had to be performed, which also became a factor to reduce the production efficiency. Further, since the tension absorbing plate 27d is formed by bending a metal plate of a relatively thin piece, it is difficult to obtain a large strength, and the tension absorbing plate 27d is deformed against an excessive tension, so that a sufficient electric wire holding force is provided. However, the pressure contact portion 27b could not be secured, and the electrical contact state at the pressure contact portion 27b might be impaired. The present invention has been made in view of the above circumstances, and provides an electric wire holding method capable of ensuring a sufficient electric wire holding force without providing a tension absorbing plate, and a pressure contact connector and a pressure contact terminal used for the same, thereby reducing manufacturing cost. It is intended to improve the reliability of the pressure contact connector.

係止手段を省略することも可能となる。In the above wire holding method, the tip end is pressed against the pressure contact portion 83c of the pressure contact terminal 83, and the base end side is pressed against the housing 41.
The electric wire 87 drawn to the front of the rear cover 55 and the front cover 63 are sequentially attached to the housing 41,
Since it is bent by 180 ° and has the U-shaped bent portion 89, a strain relief structure having high tensile strength can be formed, the electric wire 87 can be reliably held, and an external tension to the press contact portion 83c can be prevented. The effect of can be completely eliminated. In addition, the pressure contact terminal 83 is attached to the tension absorbing plate 2
Since it is not necessary to form 7d (see FIG. 9), the expanded shape of the pressure contact terminal 83 can be shortened, and the material usage amount of the parts that are frequently used can be reduced, so that the manufacturing cost can be significantly reduced. Further, since the tension absorbing plate 27d is not necessary, the total length of the press contact terminal 83 can be shortened, and thus the total length of the press contact connector 85 can be shortened. Further, by fixing the rear cover 55 to the housing 41, the upper opening and the rear opening of the terminal accommodating chamber 49 are closed, and the pressure contact terminal 83 is internally provided in an enclosed state. It is also possible to omit the locking means for fixing in 49.

大幅に低減することができる。As described above in detail, according to the electric wire holding method of the present invention, the rear cover and the front cover are sequentially attached to the housing to be bent by 180 °.
Since the wire-shaped bent portion can be formed in the electric wire, a strain relief structure having high tensile strength can be formed, a sufficient electric wire holding force can be secured, and reliability can be significantly improved. According to the press-connecting connector, the rear cover is provided at the rear part of the housing so as to be insertable, and the front cover, which is inserted from the front and is attached to the rear cover, is provided at the rear cover attached to the housing. 180
° A strain relief structure that bends and has a high tensile strength can be configured by a simple combination of parts. In the pressure contact terminal, only the electrical contact part, the wire clamping part, and the pressure contact part are sequentially formed from the tip side, so the conventional tension absorbing plate is not required, so the overall length in the expanded shape is shortened and the material of the parts used a lot. Since the amount used can be reduced, the manufacturing cost can be significantly reduced.
