Abstract

PROBLEM TO BE SOLVED: To miniaturize a lever, in the case where both a moving plate and a connector housing on a female side are moved by cam operation together with the operation of the lever. SOLUTION: A cam pin 21 of a connector housing on a female side is fitted into an fitting portion 33B of another cam pin 33 of a moving plate, so that both the cam pins 21, 33 are incorporated with each other. The incorporated cam pins 21, 33 are engaged with a cam face 44A of a lever. Consequently, it is sufficient to form a single cam groove. Therefore, the lever can be miniaturized more in comparison with the case where two cam grooves are formed to correspond to both the cam pins. Moreover, since the cam face 44A always abuts against the cam pin 21 of the connector housing on the female side receives a large fitting resistance, a stable cam operation is achieved.

At the fitting start position, the receiving opening 44B of the cam groove 44 is aligned with the upper end of the guide groove 12, and at the fitting completed position, the deep end opposite to the receiving opening 44B of the cam groove 44 is at the lower end of the guide groove 12. Align.

The female connector housing 20 has a plurality of female terminal fittings (not shown) that can be fitted to tabs of the male terminal fittings. 11 is stored. On both side surfaces of the female connector housing 20, cam pins 21 which can be tightly fitted to fitting portions 33B of the moving plate 30 with the cam pins 33 are formed. The cam pin 21 has a substantially rectangular shape as a whole, and has a flat side surface that matches the flat surface of the two projecting pieces 33A, and an arc surface 21A that is concentric with the arc surface of the two projecting pieces 33A. The outer diameter of the cam pins 21 of the female connector housing 20 is the same as the outer diameter of the end plate 35 of the moving plate 30.

Next, the operation of the present embodiment will be described. When assembling the moving plate 30 and the lever 40 to the male connector housing 10, first, the lever 40 is attached and lowered to the fitting start position, and the moving plate 30 is fitted into the hood portion 11 in this state. At this time, the cam pin 33 is fitted into the upper end of the guide groove 12, and a tab is fitted into each of the positioning holes 31 to temporarily lock the moving plate 30 at the tab holding position (see FIG. 1). In this state, the cam pin 33 is
In the receiving port 44B.

From this state, the female connector housing 20
When fitting, the lower end of the female connector housing 20 is fitted into the moving plate 30 and
The cam pins 21 of the female connector housing 20 are fitted so as to drop into the fitting portions 33B of the cam pins 33 of the moving plate 30. Thereby, both cam pins 2
The cam pins 1 and 33 are united, and thereafter, the cam pins 21 and 33 integrally perform the cam operation.

After the two cam pins 21 and 33 are combined, the lever 40 is rotated clockwise in FIGS. Then, the cam pins 21 and 33 are engaged with the cam groove 44 in a state where the cam pins 21 and 33 are united, and a cam action is exerted. Is done. Thus, when the moving plate 30 and the female connector housing 20 are integrally pulled into the hood portion 11 and the lever 40 reaches the fitting completed position, the connector housings 10 and 20 are brought into the fitted state and the moving plate is moved. 30 reaches the holding release position. Also, when the lever 40 is rotated in the opposite direction from the above in the fitted state, the cam pin 2
A pressing force from below is applied to the first and third connectors 33, and the female connector housing 20 and the moving plate 30 return to the state shown in FIG.

Here, the cam pin 2 in the cam groove 44
The engagement state between the cam surfaces 44A and the cam surfaces 44A will be described in detail. The cam surface 44A presses the cam pins 21 and 33 from above or below. However, since the cam pins 21 of the female connector housing 20 protrude above and below the projecting pieces 33A of the cam pins 33 of the moving plate 30. , The cam surface 44 over the entire rotation area of the lever 40.
A is always the cam pin 21 of the female connector housing 20.
(See FIG. 5). Further, since the end plate portion 35 of the cam pin 33 of the moving plate 30 has the same diameter as the cam pin 21 of the female connector housing 20, the cam surface 44A always comes into sliding contact with the end plate portion 35.

As described above, in the present embodiment, the cam pins 21 and 33 of both the moving plate 30 and the female connector housing 20 are engaged with the cam grooves 44 in a united state. Only needs to be done. Therefore, as compared with the conventional lever in which two cam grooves are formed corresponding to the cam pins of the female connector housing and the cam pins of the moving plate, respectively, the lever 4 of the present embodiment is used.
0 is more compact.

In the entire process of the rotation of the lever 40, the cam surface 44A is always in contact with the female connector housing 2.
Since the arc surface 21A of the 0 cam pin 21 and the end plate portion 35 of the cam pin 33 of the moving plate 30 are in sliding contact with each other, the sliding position of the cam surface 44A moves between the two cam pins 21 and 33. Compared with the case, the cam operation is stable. In particular, the fact that the cam surface 44A is always in sliding contact with the cam pin 21 of the female connector housing 20 that receives a large fitting resistance due to friction between the terminals greatly contributes to the stabilization of the cam operation.

Further, since the cam pins 21 of the female connector housing 20 are fitted into fitting portions 33B which penetrate the cam pins 33 of the moving plate 30 above and below, the two cam pins 21 and 33 are united.
Unlike the method in which the cam pins 21 and 33 are merely joined in the vertical direction, the movement of the cam pins 21 and 33 in the left-right direction is restricted, and the cam pins 21 and 33 are surely held in the combined state. In addition, during the rotation of the lever 40, the cam pins 21 and 33 are fitted into the guide grooves 12 and play in the left and right directions is regulated, so that the pressing direction from the cam surface 44A is inclined with respect to the vertical direction. Even in this state, stable cam operation is performed.

Further, since the cam plate 33 of the moving plate 30 is provided with the end plate 35, even when the female connector housing 20 is detached and only the moving plate 30 is moved in the hood 11, the cam surface 44A is at the end. It comes into sliding contact only with the arc-shaped outer periphery of the plate portion 35. Therefore, the stability of the cam operation is higher than when the cam surface 44A is in sliding contact with the protruding piece 33A. Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIGS. In the present embodiment, the cam pins of the moving plate have a different configuration from the first embodiment. Other configurations are the same as those in the first embodiment, and thus the same configurations are denoted by the same reference numerals, and description of the structures, operations, and effects will be omitted. Cam pin 51 of moving plate 50 of Embodiment 2
Is different from the cam pin 33 of the first embodiment in that there is no end plate portion and a reinforcing portion is provided.
Since there is no end plate portion, the fitting portion 51B is
It is open toward the tip. In addition, the reinforcing portion 52 connects the lower ends of the both protruding pieces 51A to each other, and
Are formed integrally so as to cover the lower surface of the lever 40, and do not cover the entire projecting region of the cam pin 51, but project from the outer surface of the peripheral wall portion 53 to a position slightly in front of the inner surface of the lever 40. Therefore, the reinforcing portion 52 is fitted into the guide groove 12 of the hood portion 11.

When the female connector housing 20 is fitted, the cam surface 44A slidably contacts the upper arc surface 21A of the cam pin 21 of the female connector housing 20 over the entire cam operation area. The cam function with respect to the female connector housing 20 having a large diameter is stably exhibited. In addition, the female connector housing 2 from the cam surface 44A.
Since the pushing force acting on the 0 cam pin 21 also acts on the cam pin 51 of the moving plate 50 via the reinforcing portion 52, the moving plate 50 also moves smoothly by the cam action. When the female connector housing 20 is detached, the cam surface 44A slides on the lower arc surface 21A of the cam pin 21 of the female connector housing 20 and also slides on the lower end of the projecting piece 51A of the moving plate 50. Be in touch. The protruding piece 51A has a thin bow shape, but since the two protruding pieces 51A are reinforced by the reinforcing portion 52, the protruding piece 51A does not bend significantly, and the cam operation with respect to the moving plate 50 is also stable. Done. Further, when the female connector housing 20 is detached and only the moving plate 50 is moved, the cam surface 44A is in sliding contact with the upper end or the lower end of the protruding piece 51A. Therefore, a stable cam operation is performed.

<Other Embodiments> The present invention is not limited to the embodiments described above with reference to the drawings. For example, the following embodiments are also included in the technical scope of the present invention. In addition, various changes can be made without departing from the scope of the invention. (1) In the above embodiment, the case where only one of the reinforcing portion and the plate end is provided on the cam pin of the moving plate has been described. However, according to the present invention, both the reinforcing portion and the plate end are provided. You may.

(2) In the above embodiment, the outer peripheral surfaces of the cam pins of both the moving plate and the female connector housing are continuous in an arc shape. However, according to the present invention, a curved surface other than a perfect circle such as an ellipse is used. May be connected to each other, and if there is no obstacle to the cam operation, they may be connected in a stepped manner. (3) In the second embodiment, the reinforcing portion is formed on the cam pin on the moving plate side. However, according to the present invention, the reinforcing portion may be formed on the cam pin on the female connector housing side.
