Since the locking portion 73 is displaced in the outer diameter direction, the annular stepped portion 79 of the center pin 60 can be moved as it is without interfering with the locking portion 73.
The outer diameter of the distal end 71 of the detection sleeve 70 and the inner diameter on the distal end side of the stepped sleeve 65 corresponding thereto are set to be slightly smaller than the outer diameter of the enlarged portion 92 of the center lock 90. As a result, when the detection sleeve 70 moves to some extent with respect to the stepped sleeve 65, the annular taper 92 ′ provided at the tip edge of the enlarged diameter portion 92 abuts against the tip 67 of the stepped sleeve 65, and this At approximately the same time, the enlarged diameter portion 92 elastically deformed in the inner diameter direction comes into contact with the taper 62 at the tip of the center pin 60, and when the cable connector 10 further approaches the board connector 80, the enlarged diameter portion 92 is The diameter is reduced by the action of the slit 93 through the contact between the taper 92 ′ and the tip 67, and as a result, the enlarged diameter portion 92 enters the inside 55 of the stepped sleeve 65.
As shown in FIG. 10, the state of the rotating member 30 in the initial fitting state is not significantly different from that in the unfitted state. From the opening window 15, the first color 30a is still visible. Although the cam mechanism is not shown in FIG. 10, it may be considered that the cam mechanism is substantially the same as FIG. 7B, as in the relationship between FIG. 7A and FIG. More specifically, only the vertical distance between the middle cam 34 of the rotating member and the mountain cut portion 54 of the slide member is different, and the operation of the cam mechanism is not affected.

Subsequently, as shown in FIGS. 11 and 12, the cable connector 10 further approaches the board connector 80, in other words, the center pin 60 moves toward the cable connector 10 along the fitting direction “α”. . When the enlarged diameter portion 92 formed in the sleeve shape by the slit 93 reaches the annular recess 68 provided on the inner wall of the stepped sleeve 65, the enlarged diameter portion 92 will return to the original diameter before being reduced in diameter. Therefore, the enlarged diameter portion 92 is fitted into the recess 68. When the diameter-enlarged portion 92 is expanded to some extent by fitting into the recess 68, the center pin 60 that has moved to the cable connector 80 side by the collision with the diameter-enlarged portion 92 is then moved by the coil spring 75. The invasion starts into the enlarged diameter enlarged portion 92.
As shown in (a) of FIG. 13, after the fitting, the first color 30a can still be seen from the opening window 15 when the lock is not completed. However, as shown in FIG. 13 (b), the outer peripheral cam 32 of the rotating member is lifted upward from the tapered groove of the ridged cam projection 45 of the support base, and the ridged portion 54 of the slide member is As a result, the rotating member 30 is moved to the cable connector 10 side while the rotating member 30 is moved to the cable connector 10 side. A force of rotational movement is generated by contact through the inclined surface.

Subsequently, as shown in FIGS. 14 and 15, the center pin 60 advances to the board connector 80 side along the fitting direction “α”, and the contact portion 61 of the center pin 60, particularly the tip thereof, It penetrates into the center lock 90 through the enlarged diameter portion 92. As a result, the enlarged diameter portion 92 is sandwiched between the stepped sleeve 65 and the contact portion 61 of the center pin 60, whereby the locked state of the cable connector 10 and the board connector 80 is maintained. It will be.
As shown in FIGS. 16 (a) and 16 (b), after this fitting and in the middle of locking, the color seen from the opening window 15 is changed from the first color 30a to the second color 30b. To change. Further, as shown in FIG. 13B, the outer cam 32 of the rotating member is inclined to the inclined surface 32 as the contact portion 61 of the center pin 60 enters the center lock 90 through the enlarged diameter portion 92. Slip in a state where “and the inclined surface 46 ′ of the columnar cam protrusion 46 of the support base 40 are in contact with each other, and further rotation is applied to the rotating member 30.

Finally, as shown in FIGS. 17 and 18, the center pin 60 is completely stopped in the fitting direction, whereby the fitting and locking are completed. At this time, the enlarged diameter portion 92 is sandwiched between the stepped sleeve 65 and the contact portion 61 of the center pin 60 at a substantially intermediate position of the contact portion 61 of the center pin 60. Therefore, the fitting between the cable connector 10 and the board connector 80 is not easily released.
As shown in FIG. 19A, the second color 30b can be seen from the opening window 15 in the state after the fitting and locking are completely completed in this way. This point will be apparent from FIG. That is, as shown in 19 (b), at this time, the outer cam 32 of the rotating member completely slides down the slope 46 ′ of the columnar cam protrusion 46 and fits into the cam groove 44 of the cam protrusion 46. Accordingly, the rotation of the rotating member 30 is completed.

  According to the above configuration, even if the sliders 22 and 22 ′ of the cable connector 10 are moved to the cable connector 10 side without fitting the cable connector 10 and the board connector 80, Since the annular step 79 provided substantially in the middle of the center pin 60 connected to the sliders 22 and 22 ′ via the slide member 50 interferes with the locking portion 73, the sliders 22 and 22 ′ do not move further. As a result, the display of the rotating member 30 is not changed. Therefore, malfunction can be prevented.

  The operation of the connector device has been described above, particularly the operation when the cable connector 10 and the board connector 80 are fitted or locked. The operation at the time of releasing the engagement or releasing the lock is clear from the above description, and thus a detailed description is omitted. However, the rotation member 30 is rotated and displayed by the movement of the center pin 60 on the cable connector side. Is changed to a state shown in FIG. However, it should be noted that when releasing the lock, it is necessary to move the cable connector 10 in the anti-fitting direction while operating the sliders 22 and 22 'to release the fitting. That is, when unlocking, it is necessary to slide the sliders 22 and 22 ′ toward the cable connector 10, thereby moving the center pin 60 toward the cable connector 10 against the force of the coil spring 75. On the other hand, since the force of the coil spring 75 works at the time of fitting or locking, there is no need to operate the sliders 22 and 22 '. Therefore, it can be said that the sliders 22 and 22 'substantially function only when unlocked. As apparent from FIG. 7B, when the lock is released, the outer peripheral cam 32 of the rotating member is adjacent to the columnar cam protrusion 46 provided on the innermost peripheral portion of the cylindrical portion 43 of the support base. Thus, it is arranged in the taper groove of the angled cam projection 45.

  In the above embodiment, the center pin 60 moves at any time point when the cable connector 10 and the board connector 80 are fitted and released, more specifically, through the movement of the center pin 60. The explanation is made on the assumption that the rotating member 30 rotates. However, by changing the cam mechanism of the rotating member 30, the support base 40, and the slide member 50, at any point in time when the cable connector 10 and the board connector 80 are fitted or released. Only the center pin 60 can be moved, and the rotating member 30 can be rotated through the movement of the center pin 60. Therefore, the present invention includes such a configuration whose design has been changed.

Moreover, although the example which confirms a fitting state with a color was shown in the above embodiment, not only the color of the rotating member 30 but the protruding state of the protrusion part which can be confirmed through the opening window 15 is utilized. It can also be confirmed. As is clear from the description of the above embodiment, the rotating member 30 can move up and down in the space 16 as it rotates, but the flat rotating plate of the rotating member 30 is arranged so that such up and down movement is visible. Instead, the protrusion 301 can be provided. FIG. 20 (a) shows an example of a rotating rod 30 ′ provided with such a protrusion 301, and FIG. 20 (b) shows a cam for a support base used for the rotating rod 30 ′. An example of the mechanism is shown. In these drawings, the same reference numerals are used for the corresponding portions of the rotating member 30 in the above embodiment, and “′” or “” is attached.
The cam mechanism of the support base 40 ′ shown in FIG. 20B corresponds to the cam mechanism of the support base 40 shown in FIG. 7, FIG. 13, FIG. 16, and FIG. . For convenience, FIG. 20B does not show the cam mechanism of the rotating rod 30 ′ or the slide member, but basically the cam mechanism of the rotating rod 30 ′ or the slide member is the same as that shown in FIG. It can be considered that they mesh with each other in the same manner. The only difference is that, in the support base 40 ′ shown in FIG. 20B, the cam groove 44 ′ is set deeper than the cam groove 44 shown in FIG. . As a result, when the cam mechanism is in the state shown in FIG. 19B, the outer peripheral cam 32 ′ of the rotating rod 30 ′ is more like the cam groove 44 ′ than in the embodiment shown in FIG. It will fall deeply and it will become difficult to visually recognize or confirm the protrusion 301 from the outside. The operation of the support base 40 ′ using the cam mechanism (cam groove 44 ′ etc.) will be described in more detail below. The engagement of the cam mechanism shown in FIG. 7 corresponds to a fitted state (the lock mechanism is in the state shown in FIG. 18). From this state, the state shown in FIGS. 13 and 16 is shifted to an unfitted state corresponding to FIG. 19 (the lock mechanism is in the state shown in FIG. 6). In particular, in the unfitted state shown in FIG. 19, the outer peripheral cam 32 is positioned in the deep cam groove 44 ′ of the support base 40 ′ shown in FIG. 20B, and at this time, the upper end of the protrusion 301 is Since it is located at the bottom side of the space 16, that is, at a position away from the opening 15, it is not visible from the opening window 15 (or difficult to see). Therefore, in this case, it can be determined that the cable connector 10 and the board connector 80 are not fitted. On the other hand, as shown in FIG. 7, in the fitting state in which the outer peripheral cam 32 is positioned in the shallow triangular groove 44 ″, the protrusion 301 is positioned at the top by the lock mechanism as shown in FIG. Therefore, since it is located near the opening 15, it can be visually recognized from the opening window 15 (or is easily visible) In addition, when the projection 301 is set to a dimension that protrudes from the opening window 15, the opening window Since the protrusion of the protrusion 301 through 15 can be confirmed not only visually but also through tactile sense, for example, it can be confirmed that the cable connector 10 and the board connector 80 are fitted with each other even in a dark work place. Therefore, the confirmation of the fitting state according to the present invention is not limited to the one using the visual state, and for example, includes the one using the tactile state.

  Furthermore, in the above embodiment, the case where the center pin 60 of the cable connector 10 moves under the action of the center lock 90 of the board connector 80 is illustrated as an example. This is a lock mechanism using a push-on / pull-off mechanism. However, it is natural that various push-on and pull-off mechanisms such as a ball can be used, and the present invention is not limited thereto. When the cable connector 10 and the board connector 80 are fitted, the center pin 60 of the cable connector 10 collides with the main body of the board connector 80 to move the center pin 60 to the cable connector 10 side. For example, by rotating the rotating member that is a visual recognition member using the movement (behavior) of Fitting state may be displayed. As described above, the present invention includes an invention in which the center pin 60 is moved not only by the action using the push-on / pull-off mechanism but also by another locking action.

  The center pin 60 does not necessarily extend linearly to the cable connector 10 side and the board connector 80 side. When the cable connector 10 and the board connector 80 are fitted to each other or released from the board connector 80, What is necessary is just to be able to move in the cable connector 10 under the action. For example, it can be L-shaped or other shapes.

  Furthermore, the rotating member is not necessarily provided on the upper portion of the center pin, and may be provided on the side portion of the center pin 60 ″ as shown in FIG. 21. The center pin 60 ″ moves in the direction indicated by the arrow “β”. Then, the hook portion 601 provided at the end portion of the center pin 60 ″ meshes with the projection 105 of the cam 104 and rotates in the direction indicated by the arrow “γ”. The rotation in the direction opposite to the “γ” direction is prevented by the return prevention spring 102. As a result, the color or the like of the rotating member that can be seen from the opening window 15 ″ also changes. It is easy for a person skilled in the art to think of such a modification. Therefore, the scope of the present invention is within the scope of the present invention. These modifications are also included.

  Since the present invention uses a mechanical structure, it can be applied not only to an electrical connector but also to various connectors such as an optical connector.
