At this time, the rotating shaft 57 of the locking member 50 is engaged with the tip end of the operation channel 37, and the hook of the terminal 40 is in the engaging groove 54 of the insertion part 53. The tip of the portion 43 is seated.

In this state, the cable 60 is inserted into the insertion space 32 of the housing 30. When the cable 60 is inserted, the locking member 50 is rotated in the direction of the arrow shown in Figure 7b. At this time, the locking member 50 rotates about the rotation shaft 57 with respect to the housing (30). Of course, the hook protrusion 45 of the tip of the hook portion 43 of the terminal 40 is seated in the engaging groove 54 of the insertion portion 53, so that the hook protrusion 45 also serves as a kind of rotation center. .

A state in which the rotation of the locking member 50 is completed is illustrated in FIGS. 8A and 8B. In this state, the locking member 50 is pushed in the direction of the arrow of FIG. 8B to allow the insertion portion 53 to be inserted into the insertion space 32 of the housing 30. At this time, the hook projection 45 of the hook portion 43 seated in the engaging groove 54 of the insertion portion 53 is guided along the inclined surface 55 '.

As the guide inclined surface 55 'and the hook protrusion 45 are guided to each other, the cable 60 is pressed by the contact portion 41, and the pattern of the contact protrusion 41' and the cable 60 is Are electrically connected to each other.

For example, the rotation shaft 57 and the operation channel 37 may be formed opposite to each other. That is, the rotation shaft 57 is formed in the side end portion 36 of the housing 30, and the operation channel 37 is formed in the interlocking finger 56.

Similarly, the formation position of the guide protrusion 59 and the insertion guide groove 39 can also be reversed from the illustrated embodiment.

In the flexible cable connector according to the present invention as described in detail above, the following effects can be obtained.

First, in the present invention, the locking member is rotated so as to move in a straight line after the locking member is mounted on the housing. Accordingly, the cable can be inserted into the housing while the locking member is rotated with respect to the housing to widen the inlet of the insertion space of the housing, thereby making it easier to insert the cable into the housing. .

And, when the locking member is completely inserted into the housing, the operator can know that the locking member is finally locked to the housing because the hook projection of the terminal exceeds the hooking jaw formed in the insertion portion of the locking member. Therefore, the assembling worker does not have to check the locking state of the locking member separately, thereby improving the workability of the assembly work.

In addition, in the present invention, in order to release the locked state of the locking member to the housing, once the locking member is removed from the housing in a straight line, the locking member must be rotated again in the housing. Therefore, even if an external force is applied to the cable while the locking member is mounted on the housing, the locking member is not rotated when the locking member is locked to the housing, thereby preventing the locking state of the locking member from being released by the external force acting on the cable. Therefore, the operation reliability of the product is also increased.
