The supporting arm portion 46 penetrates between the bottom wall 15 of the housing 10 and the mounting portion 18C of the on the road and the press-fit projection portion 46A is pushed to the lower edge of the mounting portion 18C The fixing portion 47A-1 is fixed by being fitted into the fixing portion 15B of the bottom wall 15 of the housing 10 so that the fitting 40 is prevented from coming off.

The shield plate 50 is formed by bending the metal plate member and is formed between the first terminals 20 adjacent to each other in the terminal arrangement direction as shown in Fig. 1 (Fig. 2 (A) See Fig. 4). 3 (A) to 3 (C), the shield plate 50 includes a main body portion 51 having a plate surface perpendicular to the up-and-down direction, A front contact piece 52 and a rear contact piece 53 which extend in a substantially L-shape from the side edge (the edge portion extending in the front-rear direction (the left-right direction in Fig. I have.

4, the main body portion 51 has a substantially rectangular shape with its longitudinal direction in the longitudinal direction when viewed from above. In the front-rear direction, And extends in a range including the two second terminals 30 adjacent to each other in the terminal arrangement direction. 3 (A) and Fig. 4, the main body portion 51 is formed so that the front half portion (the lower half portion in Fig. 3 (A) and the upper half portion in Fig. 4) And a notched portion 51A is formed at the front end edge. A front piece 51B is formed on both sides of the notched portion 51A. As shown in Fig. 4 (A), in the shield plate 50, the front piece 51B is entering from the back into the second groove portion 63 described later of the movable member 60 The notch portion 51A receives the partition wall portion 68 between the second groove portions 63 from the front so as to avoid interference with the movable member 60. [ A plurality of press-fit projections 51C for press-fitting the housing 10 into the shield plate holding grooves 14A are formed at the side edge of the rear half of the main body portion 51. [

3 (A) to 3 (C), the front contact piece 52 is formed so as to protrude forward from a side edge of one side of the main body portion 51 at an intermediate position in the longitudinal direction of the main body portion 51 (In a direction away from the main body 51) in the terminal arrangement direction from the front end of the elastic arm portion 52A, and a resilient arm portion 52A extending in a downwardly inclined direction toward the rear side And has an extended front contact portion 52B. The rear contact piece 53 extends from the other side edge of the main body portion 51 at a position rearward of the front contact piece 52 of the main body portion 51. [ Like the front contact piece 52, the rear contact piece 53 includes an elastic arm portion 53A that is inclined downwardly as it extends forward and is elastically displaceable in the up-and-down direction, And a rear contact portion 53B extending from the front end in the direction of the terminal arrangement (the direction away from the main body portion 51). The dimensions of the rear contact piece 53 itself are almost the same as the dimensions of the front contact piece 52 and as shown in Figs. 3A and 3B, the rear contact piece 53 The contact portion 53B is located behind the front contact portion 52B. 3 (C), the rear contact portion 53B is located slightly above the front contact portion 52B.

As can be seen from Figs. 1, 2 and 4, a first terminal 20 as a ground terminal is formed between two adjacent shield plates 50 in the terminal arrangement direction, as viewed from above The front contact portion 52B of the front contact piece 52 of one of the shield plates 50 and the rear contact portion 52B of the other shield plate 50 as shown in Figs. 2 (A) and 2 (B) And the rear contact portion 53B of the piece 53 is brought into contact with the first terminal 20. [ 2 (B), the upper end of the front half of the raised portion 26B formed on the lower arm portion 22 (see Fig. 2 (A)) of the first terminal 20 The front contact portion 52B of one shield plate 50 comes into elastic contact with the rear surface of the other shield plate 50 at the upper end surface (plate thickness surface) of the rear half of the raised portion 26B, The contact portion 53B comes into elastic contact. As a result, all the shield plates 50 and all the first terminals 20 are electrically conducted, and a good shielding effect can be obtained in the entire connector.

4, the shield plate 50 is press-fitted into the shield plate holding groove 14A of the upper wall 14 of the housing 10 from the front (upper side in FIG. 4), and the shield plate Fitting protrusions 51C of the shield plates 50 enter the opposite inner wall surfaces of the shield plate holding grooves 14A (inner wall surfaces opposed to each other in the terminal arrangement direction). The shield plate 50 mounted on the housing 10 is positioned so as to cover the two second terminals 30 from above and the shield plate 50 is disposed on both sides of the shield plate 50, The front contact portion 52B or the rear contact portion 53B elastically contacts and electrically conducts to the upper end surface of the protruding portion 26B of the first terminal 20 as a ground terminal adjacent to the terminal 50. [

In the present embodiment, the shield plate 50 is positioned within the range of the upper arm 21 of the first terminal 20 in the vertical direction. In other words, as compared with the conventional connector in which the shield member is located above the upper arm portion of the terminal, the shield plate 50 overlaps with the upper arm portion 21 of the first terminal 20, The height dimension of the connector 1 can be reduced by an amount corresponding to the plate thickness of the connector 50. Since the shield plate 50 is in contact with the first terminal 20 used as a ground terminal, a good shielding effect can be obtained.

The movable member 60 is made of the same electric insulating material as the housing 10 as a member extending over substantially the entire width of the housing 10, as can be seen in Fig.

The movable member 60 is rotatably supported between an open position seen in Fig. 6 and an intermediate position seen in Figs. 7 and 8, and a closed position seen in Fig. 6, the pivotal axis of the movable member 60 is located in the lower half of the movable member 60, and the lower half thereof is accommodated in the open space 17 formed in the front portion of the housing 10. 6, an upper half located outside the open space 17 and protruding upward from the upper wall 14 of the housing 10 becomes an operation section 61 for the user to rotate the movable member 60 have.

6, the first terminal 20, the second terminal 20, and the second terminal 20 are provided in the lower half of the movable member 60 in the width direction of the movable member 60 (as a terminal arrangement direction, The shielding plate 50 and the hydraulic arm portion 24 of each of the metal fittings 40, the front piece 51B, and the hydraulic pressure receiving portion of the first terminal 20, the shield plate 50 and the metal fitting 40 at positions corresponding to the terminal 30 and the metal fitting 40, A slit-shaped first groove portion 62, a second groove portion 63, and a third groove portion 64, which allow the arm portion 44 to enter, are formed to pass through the front and rear. The groove widths (the widths between the groove inner surfaces in the direction perpendicular to the paper surface) of the first groove portion 62, the second groove portion 63 and the third groove portion 64 are set to be equal to the widths of the first terminals 20, The width of the front piece 51B of the shield plate 50 and the plate thickness of the metal fitting 40. [ The first cam portion 65, the second cam portion 66 and the third cam portion 67 for connecting the inner surfaces of the grooves are formed in the first groove portion 62, the second groove portion 63 and the third groove portion 64 Respectively.

The first cam portion 65 formed in the first groove portion 62 corresponding to the first terminal 20 in the terminal arrangement direction can be moved in the open position with the movable member 60 And is positioned between the hydraulic arm portion 24 of the first terminal 20 and the support arm portion 26 in the vertical direction. When the movable member 60 is in the open position, the first cam portion 65 has an elongated cross section perpendicular to the terminal arrangement direction and extending in the longitudinal direction as a whole, And the upper edge of the support arm portion 26 in the vertical direction.

The rear half portion (the left half portion in FIG. 6A) of the first cam portion 65 is in contact with the inside of the pinion inner portion 6A) is formed as a supported portion 65B supported from below by the supporting arm portion 26 of the first terminal 20 in the turning process and in the closing position, As shown in Fig. The inside surface 65A has a rear edge which is in sliding contact with the pressure receiving portion 24A when guided by the pressure receiving portion 24A. The top surface 65A extends forward from the front edge of the lower portion of the top surface 65A and the front end edge directly supported by the supporting arm portion 26 at the closing position . The pivotal center of the first cam portion 65 is located in the region of the pinhole inside 65A when viewed in the terminal arrangement direction (direction perpendicular to the paper in Fig. 6A) But is not restricted by the front and rear edge portions of the recessed pressure receiving portion 24A on the left and right sides.

The second cam portion 66 formed in the second groove portion 63 corresponding to the second terminal 30 in the terminal arrangement direction can be moved in the open position by the movement of the movable member 60 And is located between the front piece 51B of the shield plate 50 and the supporting arm portion 36 of the second terminal 30 in the vertical direction. When the movable member 60 is in the open position, the second cam portion 66 has a generally rectangular cross-section at a right angle to the terminal arrangement direction. The second cam portion 66 has an upper right edge Is supported by the upper edge of the support arm portion 36 of the second terminal 30 from below. The front edge of the lower portion of the second cam portion 66 is supported in sliding contact with the upper edge of the supporting arm portion 36 in the rotating process of the movable member 60 and is formed in an arc shape. The rear edge of the upper portion of the second cam portion 66 is chamfered to form an inclined edge so that interference with the front piece 51B of the shield plate 50 during the rotation of the movable member 60 can be avoided . When the movable member 60 is brought to the closed position, the front side edge of the second cam portion 66 is extended in the front-rear direction, and the supporting arm portion 36 (See Fig. 9 (B)).

The third cam portion 67 formed in the third groove portion 64 corresponding to the metal fitting 40 in the terminal arrangement direction can be moved in the direction in which the movable member 60 And is located between the hydraulic arm portion 44 and the support arm portion 46 of the metal fitting 40 in the vertical direction. When the movable member 60 is in the open position, the third cam portion 67 has a shape in which the cross section orthogonal to the terminal arrangement direction extends as a whole in the front-rear direction. The third cam portion 67 is inclined upward as the lower front edge thereof faces forward and is inclined upward as the lower rear edge thereof is directed rearward, and the transition portion of the lower front edge and the lower rear edge And the lower edge of the protruding portion is formed as a protruding edge protruding downward. The third cam portion 67 is supported from below at the projecting edge at the open position to the support arm portion 46. [

The edge portion protruding rearward from the upper portion of the third cam portion 67 is in the shape of an arc and is in sliding contact with the hydraulic arm portion 44 during the rotation of the movable member 60 (See Fig. 8 (C)). When the movable member 60 is brought to the closed position, the front side edge of the third cam portion 67 is extended in the front-rear direction, and the supporting arm portion 46 (See Fig. 9 (C)).

6 (D), when the movable member 60 is in the open position, the lower surface of the movable member 60 contacts the housing 10 Between the restricting portions 15C of the bottom wall 15 of the main body 10 in the vertical direction.

The connector 1 of this embodiment having such a configuration is used and functions in the following manner.

First, the connector 1 is disposed at a predetermined position on a circuit board (not shown), and the connecting portion 26A of the first terminal 20, the connecting portion 36A of the second terminal 30, and the solder And fixes the fixing portion 47A together with the corresponding portions of the circuit board with the solder connection.

The movable member 60 is moved to the open position in which the movable member 60 is vertically erected as shown in FIG. 6 and the housing portion 16 of the housing 10 is moved rearward (The left side in the drawing), so that the flat conductive body F can be inserted.

Next, a connecting portion (not shown) of the flat conductive body F is inserted into the accommodating portion 16 in the forward direction with the movable member 60 in the open position as seen in Fig. The first terminal 20 is spaced from the contact portion 27A of the contact arm portion 27 by a distance slightly larger than the thickness of the connecting portion of the flat conductive member F between the pressing portion 25A of the pressing arm portion 25 and the contact portion 27A of the contact arm portion 27 And the connecting portion of the flat conductive member F is easily inserted. However, with respect to the metal fitting 40, the distance between the engaging portion 45A of the engaging arm portion 45 of the metal fitting 40 and the rectangular arm portion 47 is smaller than the thickness of the connecting portion of the flat conductive member F The flat conductive body F is lifted up by the elastic displacement of the engaging portion 45A at the front end thereof to advance to a predetermined position while widening the gap and thereafter, The engaging portion 45A is inserted into the groove F2 from above, whereby the balanced conductor F is temporarily held.

Since the movable member 60 is in the open position even when the connection portion of the flat conductive member F is inserted as described above, the contact arm portion (the rear contact portion) constituting the rear half portion of the lower arm portion 22 of the first terminal 20 27 are spaced apart from the bottom wall 15 of the housing 10 to form a clearance therebetween.

Next, the movable member 60 is rotated toward the closed position. The second cam portion 66 first makes sliding contact with the supporting arm portion 36 of the second terminal 30 when the movable member 60 starts rotating from the open position. As a result, the first cam portion 65 contacts the hydraulic arm portion 24 of the first terminal 20 and the third cam portion 67 Presses and displaces the hydraulic arm portion 44 of the metal fitting 40 upward. The first cam portion 65 and the third cam portion 67 are located at positions corresponding to the supporting arm portions 26 of the first terminals 20 and the supporting arm portions 40 of the metal fittings 40 immediately after the start of the rotation of the movable member 60, And there is no sliding contact with these supporting arm portions 26 and 46. [ In other words, all the reaction forces acting downward from the hydraulic arm portions 24, 44 toward the cam portions 65, 67 are received only at the sliding contact portions of the second cam portion 66 and the support arm portion 36 do. Therefore, the second cam portion 66 and the supporting arm portion 36 are in sliding contact with each other under a large contact pressure, and the second cam portion 66 is liable to be scraped.

7, the first cam portion 65 is engaged with the supporting arm portion 26 and the third cam portion 67 is moved with respect to the supporting arm portion 60. As a result, 66 and 67 are brought into sliding contact with the support arm portions 26, 36, 46 in the course of the rotation after this point of time. Therefore, a reaction force acting downward from the hydraulic arm portions 24, 44 toward the cam portions 65, 67 is transmitted to the sliding contact portions of all the cam portions 65, 66, 67 and the support arm portions 26, 36, The contact pressure between the second cam portion 66 and the support arm portion 36 is reduced correspondingly. In this rotation process, the cam portions 65 and 67 press the hydraulic arm portions 24 and 44 further upward.

The movable member 60 is rotated so that the cam portions 65 and 67 press the hydraulic arm portions 24 and 44 further upward so that the hydraulic arm portions 24 and 44 The pressing arm portion 25 of the first terminal 20 and the engaging arm portion 45 of the metal fitting 40 are displaced downward with the maximum displacement amount.

9, the cam portions 65, 66, 67 are located at the respective lower edges (front edges when the movable member 60 was in the open position) Is supported by the supporting arm portions (26, 36, 46), so that the movable member (60) is held in the closed position. At this time, the amount of displacement of the hydraulic arm portions 24, 44 due to being pressed by the cam portions 65, 67 with respect to the upward direction is reduced as compared with the state shown in Fig. With this configuration, a click feeling can be obtained when the cam portions 65, 66, 67 exceed the rotation angle position shown in Fig. 8 during the turning operation of the movable member 60 toward the closed position.

When the movable member 60 is brought to the closed position as described above, the pressing arm portion 25 of the first terminal 20 is displaced downward with a sufficient displacement amount, and the pressing portion 25A deforms the flat conductive member F (not shown) from above. As a result, the contact portions 27A and 37A of the contact arm portions 27 and 37 and the lower surface of the flat conductive body F come into contact with each other with sufficient contact pressure to be electrically connected. The engaging arm portion 45 of the metal fitting 40 is displaced downward with a sufficient displacement amount so that the engaging portion 45A deeply enters the engaged portion F2 of the flat conductive body F, The engaged state of the engaging portion F2 with the front edge of the engaging portion F2 is maintained and the disengagement of the flat conductive member F is reliably prevented.

As can be seen from Figs. 6 (D), 7 (D), 8 (D) and 9 (D), as long as the movable member 60 is in the normal position, A clearance is formed between the movable member 60 and the restricting portion 15C of the housing 10 so that the movable member 60 is in sliding contact with the restricting portion 15C There is no case.

In the connector 1 of the present embodiment, the cam portions 65, 66, and 67 of the movable member 60, which is an electrically insulating material, are disposed at positions where the movable members 60 are rotated The sliding contact between the support arm portions 26 and 36 of the terminals 20 and 30 made of the metal plate or the support arm portions 46 of the metal fitting 40 is repeated. As a result, the cam portions 65, 66, There is a case. Particularly, since the contact pressure between the second cam portion 66 and the support arm portion 36 of the second terminal 30 is increased between the open position shown in Fig. 6 and the pivotal position shown in Fig. 7, The second cam portion 66 is likely to be scraped.

When the cam portions 65, 66, 67 are thus clipped, the cam portions 65, 66, 67 are shifted downward from the normal position in accordance with the amount of the cut portions. If the displacement of the movable member 60 from the normal position is excessive, the locus of the cam portions 65, 66, 67 in the rotating process of the movable member 60 is different from the normal locus, It is not possible to obtain an operation feeling such as a click feeling that should be originally obtained, for example, it is difficult to operate the movable member 60 or a wrong position of the movable member 60 may occur. Further, at the closed position, the amount of elastic displacement of the pressing arm portion 25 of the terminal 20 becomes small, and sufficient contact pressure between the flat conductive member F and the terminals 20 and 30 can not be obtained, and the electric conduction state becomes unstable . The amount of elastic displacement of the engagement arm portion 45 of the metal fitting 40 is reduced and a sufficient engagement amount of the engagement portion 45A of the metal fitting 40 with respect to the engagement portion F2 of the flat conductive body F is obtained It is impossible to sufficiently prevent the floating conductor F from coming off.

In this embodiment, in the case where the movable members 60 are shifted downward from the normal position by being cut by the cam portions 65, 66, 67, any position from the open position to the closed position can be obtained, The restricting portion 15C of the bottom wall 15 of the housing 10 abuts against the movable member 60 from below. Therefore, the lowering of the movable member 60 beyond the predetermined amount is regulated, and the further cam portions 65, 66, 67 are prevented from being cut. As described above, the restricting portion 15C is formed to have a height dimension such that the deviation of the loci of the cam portions 65, 66, 67 in the turning process of the movable member 60 falls within the permissible range, As a result, the amount of descent from the normal position of the movable member 60 does not become excessive, and the operation feeling of the movable member 60, the contact between the flat conductive member F and the terminals 20 and 30, The engagement state of the flat conductive member F and the metal fitting 40 can be satisfactorily maintained.

The regulating portion 15C of the housing 10 abuts against the movable member 60 only when the movable member 60 descends a predetermined amount from the normal position. If the restricting portion 15C abuts on the movable member 60 even when the movable member 60 is in the normal position, it is possible to prevent the misalignment of the movable member 60 There may be some problems. For example, when the regulating portion 15C abuts on the movable member 60 in the normal position, the cam portions 65, 66, 67 of the movable member 60, the terminals 20, 30, An unnecessary gap is formed between the support arm portions 26, 36 and 46 of the support arms 40 and 40 so that the cam portions 65, 66 and 67 are not supported by the support arm portions 26, May occur.

In contrast, in the present embodiment, when the movable member 60 is in the normal position, a gap is formed between the movable member 60 and the regulating portion 15C so that the movable member 60 The restricting portion 15C comes into contact with the movable member 60 only when the cam portions 65, 66, 67 are lowered by a predetermined amount from the normal position. Therefore, according to the present embodiment, even if dimensional errors or mounting errors occur during manufacture of the connector 1, the above-described problems can not be caused as long as these errors are within the allowable range. As a result, according to the present embodiment, the connector 1 can be easily manufactured.
