The male terminal 81 is formed, for example, by bending in a substantially crank shape, and the other connecting portion (not shown) following the one contact tab portion 81a is connected to a terminal of a rear defogger heat wire by soldering. A hole 84 for locking is formed in the center of the contact tab 81a. The male terminal 81 remains exposed to the outside, and is not housed in the connector housing 85 like the female terminal 83.

る。The female terminal 83 has a box-shaped electric contact portion 8 on one side.
8, and the other side has an electric wire connection part (crimp part) 89. An elastic contact piece 90 is provided inside the electric contact portion 88, and the elastic contact piece 90 is formed with a locking projection 91 with respect to the hole 84 of the male terminal 81. As shown in FIG.
The contact tab 81a is inserted and connected between the elastic contact piece 90 of the female terminal 83 and the holding wall 92, and the locking projection 91 is engaged with the hole 84, so-called positive locking is performed. The engagement between the terminals 81 and 83 is released by displacing the elastic contact piece 90 downward by a mechanism (not shown) and strongly pulling the connector 82 having the male terminal 81 or the female terminal 83.

必要があり、接続作業性が悪いという問題があった。However, in the above-mentioned conventional structure, since there is no connector housing on the male terminal 81 side, the male and female connector housings cannot be fitted and locked together. Therefore, the male terminal 8 is inserted with a strong force to insert the male terminal 81 into the female terminal 83.
In particular, when the male and female terminals 81 and 83 are large and the contact pressure between the terminals 81 and 83 is large, the male terminal 81 is pushed in the insertion direction with a stronger force.
3 is strongly pressed toward the fixed male terminal 81 (when the male terminal 81 is fixed).
And the connection workability is poor.

いという問題があった。Further, since a large force is required to insert the male terminal 81, the male terminal 81 is likely to be half-inserted (incompletely inserted) with respect to the female terminal 83. For example, there is a concern that the male terminal 81 easily comes off from the female terminal 83. Further, when the terminals 81 and 83 are large or the number of poles of the terminals 81 and 83 is large, the sliding resistance between the terminals at the time of connecting the terminals increases, and a larger insertion force is required for the male terminal 81. As a result, there is a problem that the connection workability is deteriorated and that the male terminal 81 is easily half-inserted.

ための良好な手段がなく、その手段が切望されていた。Conventionally, when a male connector containing a female terminal is fitted to a female connector (not shown) containing a male terminal, the insertion of both the male and female terminals is performed with a small force. As a means, for example, a structure in which a lever having a cam groove is provided in one connector housing and a driven protrusion which engages with the cam groove is provided in the other connector housing is known. However, there is no good means for securely connecting the male terminal 81 having no connector housing to the female terminal 83 in the mating connector 82 with low insertion force and without half-insertion. It had been.

である。In the fully locked state of the spacer 7, the rear end 23a of the projecting piece 23 of the pressed portion 21 faces the rear end surface 31a of the cutout 31 of the spacer 7 with a slight gap as shown in FIG. The female terminal 4 is positioned so as to prevent the female terminal 4 from slipping back. Thereby, connector housing 2 (FIG. 1)
The locking force of the female terminal 4 with respect to is increased. The locking arm (reference numeral 87 in FIG. 9) for female terminal primary locking can be omitted.

ズに行わせることができる。The final release of the locking of the spacer 7 is performed by the operation plate 28.
(FIG. 7) is pulled out by squeezing with a flathead screwdriver or the like, and the center elastic contact piece 6 is pushed down with a jig rod or the like in the temporarily locked state of the spacer 7 in FIG.
By releasing the engagement with (FIG. 8), the male terminal 9 can be easily pulled out with low force. This also improves maintainability. At this time, if a downward inclined surface (not shown) is provided on the side edge 31b (FIG. 3) of the cutout portion 31 of the spacer 7, the sliding contact between the pressing portion 30 and the pressed portion 21 is performed smoothly. Can be made.

It is also possible to provide an inclined surface (not shown) for sliding contact with. Further, the shape of the pressed portion 30 is not limited to the horizontal L-shape, and may be a shape projecting obliquely from the connecting portion 20. Also, the central elastic contact piece 6 is eliminated, and a pair of elastic contact pieces 5 and 5 or one elastic contact piece 5 is provided.
Can also be used. The pressed portion 21 is formed integrally with one elastic contact piece 5 without using the connecting piece 20.
It is also possible to use one elastic contact piece 5 for contact and one elastic contact piece 6 for locking.

る。As described above, according to the first aspect of the present invention, the pressing portion of the spacer presses the pressed portion of the female terminal in the direction opposite to the bias of the elastic contact piece, so that the elastic contact piece is covered. It bends in the non-contact direction integrally with the pressing portion. As a result, the contact allowance of the elastic contact piece to the mating male terminal is reduced or eliminated, the insertion force of the male terminal to the female terminal is reduced, and the male terminal is easily inserted into the female terminal with a small force. When the spacer is further pushed in, the elastic contact piece is restored while entering the notch, and elastically contacts the male terminal. Thus, the male terminal can be easily connected to the female terminal in the connector housing in a single state (a state in which the male terminal is not accommodated in the connector housing) with low power, and the male terminal can be inserted with low power. The half-insertion of the male terminal is prevented. For example, the connector connection of the defroster on the rear window of the vehicle can be easily performed with good workability and securely without the half-insertion of the male terminal.

面にスペーサの押圧部を摺接させる場合も同様である。According to the second aspect of the present invention, when the spacer is inserted, the pressed portion of the female terminal smoothly slides while being guided, for example, along the inclined surface of the end portion of the pressing portion, so that the elastic contact piece is formed. It is reliably pushed down in the opposite direction. Thereby, the insertion operation of the spacer and the bending operation of the elastic contact piece are smoothed. The same applies to the case where the pressing portion of the spacer slides on the inclined surface at the end of the pressed portion of the female terminal.

接続作業性が向上する。According to the third aspect of the present invention, the male terminal is locked while slidingly contacting the central locking elastic contact portion,
In this male terminal locked state, the pressing operation of the spacer, that is, the bending operation of the elastic contact pieces on both sides in the non-contact direction can be performed, so that the elastic contact pieces can be bent without worrying about the male terminal coming off. Operation can be performed reliably,
Connection workability is improved.

正確に行われる。According to the fourth aspect of the present invention, the elastic contact piece of the female terminal is pushed down while the spacer is temporarily locked, and the male terminal is inserted into the female terminal in this state. Since the position of the spacer is defined by the temporary locking means, the depressed state of the elastic contact piece is accurately maintained, and the low force insertion of the male terminal is performed accurately.

Since the position of the spacer is defined by the final locking means, a good connection between the male and female terminals can be maintained. In addition, since the rear end of the pressed portion of the female terminal abuts against the inner surface of the notch of the spacer in the fully locked state, the female terminal is prevented from slipping back, and the conventional female terminal locking means for the connector housing is unnecessary.
