Description of the Related Art In general, a press-connecting terminal of a press-connecting connector has a structure in which a covered electric wire is pressed into an opposing press-connecting blade to cut a coating of the electric wire, thereby conducting the core wire and the press-connecting blade. This press-connecting connector has the advantage of being suitable for mass production, but has the disadvantage that the strength of the press-contact portion against the wire pulling force is low. An example of this type of press-connecting connector having a so-called strain relief structure for supporting a bent portion formed on an electric wire is disclosed in, for example, Japanese Utility Model Application Laid-Open No. 61-353.
No. 69 is described with reference to FIGS.

A locking claw 25 is provided at the front end of the cover 15, and the locking claw 25 is configured to lock on the back surface of the front wall 11. On the other hand, as shown in FIG. 9, an electric contact portion 27a, a press contact portion 27b, a wire clamping portion 27c, and a tension absorbing plate 27d are sequentially formed on the press contact terminal 27 from the front.

を目的とする。However, in the conventional press contact connector, in order to form the bent portion 31, a tension absorbing plate 27d must be formed on the press contact terminal 27.
As a result, the entire length of the expanded shape of the press contact terminal 27 becomes extremely long, the amount of material used increases, and the press contact terminal 27 becomes expensive. In particular, since the press contact terminal 27 is the most frequently used component per press contact connector, it causes a significant increase in cost. Also, the tension absorbing plate 27d
In order to form from a flat plate, a complicated bending process had to be performed, which was a factor of reducing production efficiency. Further, since the tension absorbing plate 27d is formed by bending a relatively thin small metal plate, it is difficult to obtain a large strength, and it is deformed by an excessive tension. Therefore, the electrical contact state at the press contact portion 27b may be impaired. The present invention has been made in view of the above circumstances, and provides a wire holding method and a press-connecting connector and a press-connecting terminal used therefor that can secure a sufficient wire-holding force without providing a tension absorbing plate, thereby reducing manufacturing costs. An object is to improve the reliability of a press-connecting connector.

る。In the electric wire holding method, the electric wire is once drawn out to the front side of the housing by inserting the rear cover from the rear of the housing, and then the electric wire is pulled rearward by inserting the front cover from the front of the housing. The wire is bent to form a U-shaped bent portion which is bent at 180 °. As a result, a strain relief structure in which the upper and lower plates of the rear cover are tension absorbing plates is formed, and the tensile strength is secured and the electric wires are held. In the press-connecting connector, the rear cover is insertably provided at the rear of the housing so that the wires can be pulled out in the front direction, and further inserted into the rear cover attached to the housing from the front and attached to the rear cover. By providing the front cover, the electric wire can be bent by 180 °, and a strain relief structure that forms a U-shaped bent portion in the electric wire can be configured by a combination of simple components. In the press contact terminal, only the electric contact portion, the wire holding portion, and the press contact portion are sequentially formed from the front end side, and since the conventional tension absorbing plate is unnecessary, the overall length in the developed shape is shortened, and the wire is drawn forward. In this state, the base end side of the tip end of the wire pressed against the press contact portion is crimped and held by the wire holding portion, and when the wire is bent by 180 °, the press contact portion is protected from external tension by the wire holding portion.

係止手段を省略することも可能となる。In the above-described electric wire holding method, the distal end is pressed against the press contact portion 83c of the press contact terminal 83, and the proximal end is connected to the housing 41.
The electric wire 87 pulled out in front of the housing 41 sequentially attaches the rear cover 55 and the front cover 63 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 securely held, and the external tension to the press contact portion 83c can be reduced. Can be completely eliminated. Also, the tension absorbing plate 2 is
Since it is not necessary to form 7d (see FIG. 9), the development shape of the press contact terminal 83 is shortened, and the amount of material used for a frequently used component can be reduced, so that the manufacturing cost can be significantly reduced. Further, since the tension absorbing plate 27d becomes unnecessary, the entire length of the press contact terminal 83 can be shortened, and thus the entire 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 provided in an enclosed state. It is also possible to omit the locking means for fixing in 49.

FIG. 6 is a perspective view of a press-connecting connector provided with an opening / closing plate. In the press-contact connector 91 according to this modification, the front cover 63 described above is not required, and the open / close plates 95 a and 95 are provided on the upper and lower surfaces of the housing 41 via thin hinges 93.
b is provided. Locking claws 97 are protruded from the ends of the open / close plates 95a and 95b.
When the housing 5b is tilted rearward of the housing 41 via the hinge 93, the housing 5b is engaged with the engagement hole 99 formed on the rear surface of the cover 55 after being attached to the housing 41. That is, the electric wire 87 pulled out from the electric wire outlet 61 by the rotation of the open / close plates 95a and 95b is
Similarly to the case where 3 is inserted, it is bent rearward of the housing 41 so as to be bent 180 ° around the wire take-out portion 61. According to the press-connecting connector 91, the front cover 63 becomes unnecessary, and a reduction in material cost can be expected, and the number of parts is reduced.
Parts management can be facilitated.

大幅に低減することができる。As described in detail above, according to the wire holding method according to the present invention, the rear cover and the front cover are sequentially attached to the housing to be bent by 180 ° and to be bent by 180 °.
Since the U-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 the reliability can be significantly improved. According to the press-connecting connector, the rear cover is provided so as to be freely insertable at the rear of the housing, and the front cover which is inserted from the front and is attached to the rear cover is provided on the rear cover attached to the housing. 180
° The strain relief structure with high tensile strength to be bent can be constituted by a combination of simple components. In the crimping terminal, only the electrical contact part, the wire clamping part, and the crimping part are sequentially formed from the front end side, so that the conventional tension absorbing plate is not required, so the overall length in the developed shape is shortened, and the material of frequently used parts Since the amount used can be reduced, the manufacturing cost can be significantly reduced.
