First, FIG. 7 shows a state in which the slide 50 is released from the housing 30 in the connector of the present invention. That is, a state in which the fixed driving unit 51 of the slide 50 is released from the insertion space 32 of the housing 30 is shown. In this case, the slide 50 may be pulled out to the position where the hooking jaw 55 of the guide arm 54 is hooked to the removal prevention jaw 38 of the elastic guide 36.

On the other hand, it will be described for mounting the slide 50 to the housing 30 for reference. Since the elastic guide 36 has a shape like a cantilever beam, the tip may be elastically deformed so that the tip is closer to or farther from the side of the housing 30 to some extent. Therefore, while the front end of the guide arm 54 of the slide 50 is positioned outside the front end of the elastic guide 36, the elastic guide 36 is elastically deformed by pressing the front end of the elastic guide 36. The tip of the guide arm 54 may be seated in the guide channel 37 of the elastic guide 36. In this case, the elastic guide 36 may be elastically deformed to the extent that the hooking jaw 55 of the guide arm 54 can easily pass over the removal preventing jaw 38.

Of course, the guide arm 54 can also be elastically deformed, so that the slide 50 can be assembled to the housing 30 by elastically deforming the guide arm 54 to some extent. In this case, the guide arm 54 may be elastically deformed so that the width between the guide arms 54 is relatively wider.

In this way, once the guide arm 54 is seated in the guide channel 37 of the elastic guide 36, the assembly of the slide 50 is completed when the guide arm 54 or the elastic guide 36 is restored to a circular shape. . That is, the guide arm 54 may move along the guide channel 37 of the elastic guide 36, and the stopper bump 38 of the guide jaw 55 and the elastic guide 36 may move. ) Can be walked together to prevent the slide 50 from randomly exiting the housing 30.

As shown in FIG. 7, when the cable 60 is inserted into the insertion space 32 in the direction of arrow A, and the slide 50 is pushed in the direction of arrow B, the slide 50 is connected to the housing 30. ), And the cable 60 is fixed by the terminal 40.

As the fixed driving unit 51 is inserted into the insertion space 32, the protrusion 43 ′ of the deformation driving unit 43 is guided to the pressure inclined surface 57. Therefore, as the fixed drive unit 51 is inserted, the protrusion 43 'is guided to the pressure inclined surface 57 which gradually increases in height so that the rear end of the deformable drive unit 43 has a relatively high position.

In this case, the hook portion 42 is adjacent to the contact portion 44 while elastic deformation occurs in the connecting portion 41. In this case, the cable 60 between the contact portion 44 and the hook portion 42 of the terminal 40 is seized and fixed by the push protrusion 42 'and the contact protrusion 44'. For reference, the deformation groove 41 'formed at the portion where the connection portion 41 and the body portion 40' are connected allows the elastic deformation to be smoothly while the force is applied to the connection portion 41 evenly.

Meanwhile, FIG. 9 illustrates a state in which the slide 50 is completely inserted into the housing 30. At this time, the projection part 43 'of the deformable driving part 43 provided in the terminal 40 passes through the pressure inclined surface 57 formed on the upper surface of the fixed driving part 51 of the slide 50 to the hook groove 59. It is seated. Of course, the height of the hook groove 59 is formed higher than the height of the portion before the pressure inclined surface (57). As a result, the slide 50 is locked to the housing 30 so as not to be detached arbitrarily.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self-evident.
