[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and improves the detachable lever of a lever fitting type connector to prevent the lever from being detached during a fitting operation. It is an object of the present invention to provide a lever fitting type connector that prevents the lever from being easily removed after the fitting is completed.

[0005]

In order to achieve the above object, in the lever fitting type connector of the invention described in claim 1, a pair of mating connectors are inserted / removed by a rotating operation of a detachable lever. A lever fitting type connector,
One connector housing is provided with a support projection for the lever, the other connector housing is provided with an introduction projection, and the lever has a shaft hole, a guide groove having an opening end at an edge portion around the shaft hole, and the shaft hole. The guide groove is characterized by being provided with a guide groove communicating with the guide groove and a release piece extending on the opposite side of the guide groove from the shaft hole.

[0006] It is preferable that the lever is a lever in which opposing support plates are connected by an operating portion (claim 2).
It is preferable that the releasing piece is a releasing piece having a stopper projecting from the end (claim 3). It is preferable that the guide groove is a guide groove having a slope whose depth gradually increases toward the guide groove (claim 4). It is effective that the release piece is a release piece provided with a fine protrusion on the outside (claim 5).

A lever-fitting type connector according to a sixth aspect of the present invention is a lever-fitting type connector in which a pair of mating connectors are inserted and removed by rotating a detachable lever. A support projection for the other connector housing, and an introduction projection on the other connector housing, the lever has a shaft hole, a guide groove having an opening end at an edge portion around the shaft hole, and a gap between the shaft hole and the guide groove. It is characterized in that a guide groove for communicating with the guide groove and a protruding ridge protruding outside the guide groove are provided.

[0008] It is preferable that the lever is a lever formed by connecting supporting plates facing each other with an operating portion (claim 7).
While providing a stopper on one connector housing,
It is preferable that the restraint step portion is provided outside the protrusion of the lever (claim 8). It is effective that the guide groove is a guide groove in which the depth gradually increases toward the guide groove.

[0009]

According to the lever-fitting type connector of the invention described in claim 1, since the support plate is bent by pressing the release piece provided on the lever, the corner of the connector housing serves as a fulcrum. The shaft hole of the lever can be easily removed from the protrusion. Further, as described in claim 4, the guide groove of the lever is formed as a guide groove having an inclination whose depth gradually increases toward the guide groove.
It is possible to automatically move the support projections, which are disengaged from the shaft holes, to the guide grooves along the guide grooves, which makes it easier to remove the lever. On the other hand, when mating and unmating the connectors with each other, the shaft hole of the lever is fitted into the connector housing, so the lever does not come off unless the release piece is pressed, and the lever operation for mating and unmating is easy. The workability is improved.

According to the lever fitting type connector of the invention described in claim 6, by fitting the connectors to each other by the lever and then further rotating the lever, the protrusion provided on the outside of the guide groove of the lever is formed. The stopper provided on the connector housing is passed over, and at this time, the distance between the support plates is expanded, and the shaft hole of the lever is removed from the support protrusion of the connector housing. Further, as described in claim 9, the guide groove is formed as a guide groove having an inclination in which the depth gradually increases toward the guide groove, so that the support projections that are disengaged from the shaft hole are formed along the guide groove. The lever can be automatically moved to the guide groove, which facilitates the removal of the lever. Also, when mating and unmating the connectors with each other, the shaft hole of the lever is fitted into the support protrusion of the connector housing, and the lever will not come off unless the lever is excessively rotated. The lever operation is easy and the workability is improved.

Then, as shown in FIG. 14, the connector housing 2 is fitted in the connector housing 1 ', and the guide projection 6 of the connector housing 2 is inserted into the guide groove 4 of the connector housing 1'and the guide groove of the lever L'. Match 20. Then, by holding the operating portion 18 of the lever L ′ and rotating it in the direction of the arrow, as shown in FIG.
Both connectors M'and F are fitted together.

At this time, the locking projection 7 of the connector housing 2 pushes up the locking hook 5a of the locking arm 5 of the connector housing 1'from below to enter the insertion groove 5b and project from the insertion groove 5b. 5a and the connectors M'and F are locked together (see FIG. 16).

Further, when the lever L'is rotated in the direction of the arrow, as shown in FIG. 16, the protrusion 22 rides on the stopper 16 of the connector housing 1 ', and the bearing plates 17 and 17'.
The space between and can be expanded. At this time, the introduction protrusion 6 moves to the releasing moving portion 20a of the guide groove 20. By expanding the support plates 17 and 17 ', the shaft hole 19 of the lever L'
However, the lever L'is removed from the support protrusion 3 and automatically introduced into the guide groove 20 along the inclination of the guide groove 21, and the lever L'is removed from the connector housing 1 '.

[0029]

According to the lever fitting type connector of the present invention, the lever can be easily removed from the connector housing by pressing the release piece provided on the lever, and the connectors can be fitted together. In the case of disengagement, the lever does not come off unless the release piece is pressed, so that the lever operation for fitting and disengagement is facilitated and the workability is improved. Further, as described in claim 4, by providing the lever with the inclined guide groove, the support protrusion automatically moves along the guide groove when the shaft hole of the lever is removed from the support protrusion of the connector housing. The lever can be moved to the guide groove, which makes it easier to remove the lever.

According to the lever fitting type connector of the invention described in claim 6, by fitting the connectors to each other by the lever and then further rotating the lever, the shaft hole of the lever can be easily opened from the support projection of the connector housing. In addition, the connectors do not come off when the connectors are fitted to or removed from each other unless the levers are excessively rotated. Therefore, the lever operation for fitting and releasing is facilitated and the workability is improved. . Furthermore, as described in claim 9,
The provision of the inclined guide groove makes it much easier to remove the lever. Further, in the lever fitting type connector of the invention described in each claim, the lever cannot be removed unless the mutual fitting of the connectors is completed, so that the fitting failure can be easily found and the failure due to the fitting failure can be prevented. There are great advantages such as.
