Actions and effects of the present invention

<Invention of claim 1> When the operating lever is swung in one direction by pressing one of the pressing portions, the holding member is brought to the release position, and in this state, the sheet-shaped conductive member is placed between the holding member and the terminal. Road is inserted. Next, when the other pressing portion is pressed to swing the operation lever in the opposite direction, the holding member is brought to the holding position, and the inserted sheet-shaped conductive path is sandwiched between the holding member and the terminal. Thus, the sheet-like conductive path is kept in contact with the terminal. The operation of rotating the holding member between the release position and the holding position can be performed by alternately pressing both pressing portions of the operation lever, so that the work of connecting the sheet-like conductive paths can be performed efficiently.

<Invention of Claim 2> It becomes easier to press the operation lever, and the workability can be further improved. <Invention of Claim 3> When the holding member is rotated to the release position by one-way swing of the operation lever, the holding member and the operation lever are temporarily held at the release position. It is not necessary to hold the operation lever during the subsequent insertion work of the sheet-shaped conductive path, and the sheet-shaped conductive path can be inserted more easily.

<Invention of Claim 4> Since the lead portion of the terminal provided so as to protrude from the connector housing and the pressing portion of the operation lever are arranged so as to protrude in the same direction, the entire connector housing can be made compact. .

<Invention of claim 5> Even if a pulling force is applied to the sheet-like conductive path in the direction of winding the operating lever in front of the insertion opening in the holding state, the operation end of the operation lever is opposite to the insertion opening. Since the sheet-shaped conductive path is directed to the side, the sheet-shaped conductive path is not hit, and the operation lever is prevented from rotating in the release direction, so that the sheet-shaped conductive path is maintained in a sandwiched state. That is, the reliability of the connection of the sheet-like conductive paths is improved.

The pushing is stopped by being abutted against the abutting portions 22A and 22B, respectively. At this time, the locking projection 28 provided on the rear end side of the base 23 is attached to the mounting groove 2.
It is attached to the wall by cutting into the wall of No. 2. Here, as shown in the figure, the hook portion 26 at the tip of the arm 24 protrudes from the front surface of the main body portion 6, and an upper bearing portion 29 is formed therebetween, and forms a pair with the lower bearing portion 8 described above. Bearing portion 30 of swing shaft 39 of operation lever 3 to be described later
Is configured.

Next, the operation lever 3 will be described. The operation lever 3 is formed of a synthetic resin material, and is formed in a frame shape with an open front edge so as to surround right and left side edges from a rear edge of the ceiling portion 10 on the upper surface of the connector housing 1. As shown in FIG. 2, the front ends of the left and right sides of the operation lever 3 can protrude forward from the front surface of the ceiling 10 while the inner width is widened. In the portion that is more protruding, the outer edge is formed to protrude outward, whereby the pair of first
A pressing portion 31 is formed. On the upper surface of each first pressing portion 31, a non-slip 32 having irregularities repeated in the front-rear direction is formed. On the other hand, the rear side of the operation lever 3 is formed to be thick over the entire length, and this rear side is the second pressing portion 34. On the upper surface of the second pressing portion 34, a non-slip 35 having irregularities repeated in the front-rear direction is also formed.

At the distal ends of the left and right sides of the operation lever 3,
A support plate 37 is formed so as to hang down on the lower surface of the portion that is widened inward. As shown in FIG. 4A, the support plate 37 has an inverted trapezoidal shape in which the rear edge is vertical and the front edge is gradually inclined rearward toward the lower end. 7 are formed so as to be sandwiched from both right and left sides. A swing shaft 39 is formed between the two support plates 37 so as to penetrate the two support plates 37. Therefore, the first pressing portion 31 and the second pressing portion 34 are disposed on both front and rear sides of the swing shaft 39. As shown in FIG. 8, a tapered guide surface 40 is formed at the rear and lower semicircular portion of the end surface of the swing shaft 39 protruding outside the support plate 37.

The operation lever 3 is arranged such that the guide surface 40 of the projecting end of the swing shaft 39 is moved from the state shown in FIG. 1 to the arm 24 of the holder 21 attached to the connector housing 1.
And is pushed in obliquely from the front against the introduction portion 27 at the tip of. The swinging shaft 39 is pushed in while the arm 24 of the holder 21 is spread by the guide surface 40, and when the projecting end of the swinging shaft 39 comes out behind the hook 26 of the holder 21, the arm 24 returns to its original shape. The swing shaft 39 is fitted to the bearing 30. Specifically, the lower surface side of the region between the two support plates 37 of the swing shaft 39 is received by the lower bearing portion 8 of the connector housing 1, and the two support plates 3 of the swing shaft 39
The upper surface side of the protruding end from 7 is fitted into the upper bearing portion 29, whereby the operation lever 3 is swingably supported on the connector housing 1 about the swing shaft 39.

The swinging of the operating lever 3 in the clockwise direction in FIG. 4 is restricted by the lower surface of the second pressing portion 34 coming into contact with the upper surface on the rear end side of the main body 6 of the connector housing 1.
At this time, the operation lever 3 takes a horizontal posture as shown in FIG. 4A, and this position is the holding position. The operation lever 3 can swing 45 degrees counterclockwise from the holding position as shown in FIG. 3B, and this position is the release position. The operation lever 3 can be temporarily held so as not to swing from the release position to the holding position side by its own weight. Therefore, as shown in FIGS. 1 and 8 and 9, temporary holding recesses 42 are formed on the left and right side surfaces on the distal end side of the extension portion 7 of the connector housing 1, and both support plates of the operation lever 3 are provided. 37, the temporary holding recess 42 is provided when the operation lever 3 swings to the release position.
Is formed with a projection 43 which can be fitted into the projection.

In a region between the two supporting plates 37 on the swing shaft 39, a holding portion 45 functioning to hold the ribbon cable 4 between the terminal 2 and the supporting plate 37 is integrally formed. The holding portion 45 is provided with the operation lever 3, that is, the swing shaft 3.
4A, the distal end surface of the swing shaft 39 projects obliquely forward from the upper surface side, and the leading end surface serving as the holding surface 46 takes a horizontal posture. 46
Is set to approach the projection 17 of the contact piece 15 of the terminal 2. On the other hand, when the operation lever 3 is swung to the release position, as shown in FIG. The gap is set to be larger than the thickness of the ribbon cable 4 between the projection 17 and the projection 17.

The first embodiment has the above structure, and its operation will be described below. Connector housing 1
The terminal 2 and the holder 21 are provided in the same manner as described above.
Is mounted, and the operating lever 3 is
Is fitted to the bearing portion 30. Operation lever 3
Is usually stored and transported while being swung to the holding position shown in FIG. The connector housing 1 is fixed by soldering the mounting portion 25 of the holder 21 at a predetermined position on the printed wiring board, and the lead 16 of each terminal 2 is also soldered to the corresponding conductive path of the printed wiring board. Connected.

The procedure for attaching the ribbon cable 4 to the connector housing 1 fixed to the printed wiring board as described above is as follows. First, from the state of FIG. 4 (A), the first pressing portion 31 of the operation lever 3 is pressed, and the operation lever 3 is moved counterclockwise in FIG.
The operator swings five degrees, and brings the operation lever 3 to the release position as shown in FIG. When the operation lever 3 is swung to the release position, as shown in FIG. 9, the protrusion 43 of the operation lever 3 is fitted into the temporary holding recess 42 of the extension 7 of the connector housing 1. , The operation lever 3 is temporarily held at the release position. Here, the distance between the holding portion 45 protruding from the swing shaft 39 and the protruding portion 17 of the contact piece 15 of the terminal 2 is widened.

In this state, the ribbon cable 4 is inserted from the front between the contact piece 15 of the terminal 2 and the holding portion 45 with the conductive path on the upper surface. As shown by the chain line in FIG. 4B, the insertion is restricted when the leading end of the ribbon cable 4 abuts on the restricting portion 19. If so, the second
The operating lever 3 is swung clockwise while pressing the pressing portion 34 to remove the projection 43 from the temporary holding concave portion 42, and is brought to the holding position shown in FIG. Accordingly, the holding portion 45 also rotates in the same direction.
5 is deformed upward while holding the holding surface 45 of the holding portion 45.
The ribbon cable 4 is elastically sandwiched between the contact piece 15 and the projection 17 of the contact piece 15. As a result, each conductive path of the ribbon cable 4 is kept in contact with the corresponding contact piece 15 of the terminal 2.

On the other hand, when removing the ribbon cable 4, the first pressing portion 31 is pressed from the state shown in FIG.
When the operation lever 3 is swung to the release position shown in FIG. 4B, the gap between the holding portion 45 and the contact piece 15 is widened, and the clamping force is removed. Can be removed from.

As described above, according to the first embodiment, the first pressing portion 31 and the second pressing portion 34 of the operation lever 3 are alternately pressed and rocked, so that the holding portion 45 is moved to the ribbon cable. Since the pivoting operation can be performed between the release position allowing insertion / removal of the cable 4 and the holding position sandwiched between the terminal 2, the connection operation of the ribbon cable 4 can be performed easily and efficiently. In addition, since the non-slip portions 32 and 35 are formed on the pressing portions 31 and 34, the pressing operation itself of the operation lever 3 is extremely easy.

When the holding portion 45, that is, the operation lever 3 is swung to the release position, the operation lever 3 is temporarily held at the release position. Therefore, when the ribbon cable 4 is subsequently inserted, the operation lever 3 is not moved. It is not necessary to bother the user, and the operation of inserting the ribbon cable 4 can be performed smoothly. Further, the lead portion 16 of the terminal 2
Is arranged so as to protrude from the front side of the main body 6 of the connector housing 1 in a space where the first pressing portion 31 side of the operation lever 3 protrudes. Compared to the case where the connector housing 1 is housed by protruding from the rear side, the depth dimension of the entire connector housing 1 can be reduced, which is convenient for storing and transporting the connector housing 1.

Further, as shown in FIG. 4C, when the ribbon cable 4 is connected to the connector housing 1 attached to the printed wiring board, a space is provided above the opposite side of the printed wiring board. In many cases, a ribbon cable 4 is provided in front of a so-called insertion port of the connector housing 1 as shown by an arrow in FIG.
May be pulled while being bent upward. In this case, the first pressing portion 31 of the operation lever 3 is on both sides of the ribbon cable 4 therebetween, and the other second pressing portion 34 is in a position facing the opposite side to the opening direction of the insertion port. In any case, there is no possibility that the ribbon cable 4 will hook the operation lever 3 and rotate in the release direction. That is, even if the above-described tensile force acts on the ribbon cable 4, the connection state is maintained, and high connection reliability is obtained.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment,
The structure of a portion for temporarily holding the operation lever 3 at the release position is modified. Therefore, in the second embodiment,
A cam portion 51 having a substantially triangular shape protrudes from a part of the outer peripheral surface of a protruding end of the swing shaft 39 of the operation lever 3 from the support plate 37. Then, as shown in FIG.
When the operation lever 3 is in the holding position, the vertex 52 of the cam portion 51 is located behind the vertical line X passing through the axis O of the swing shaft 39, and the front inclined portion 53 of the cam portion 51 is in the natural state. The lower end edge of the arm 24 of the holder 21 is located on the other hand, and when the operating lever 3 is at the release position, as shown in FIG. The setting is such that the lower edge of the arm 24 of the holder 21 is pressed forward of the vertical line X passing through the center O.

That is, when the operation lever 3 is pivoted counterclockwise from the holding position shown in FIG.
When the lower edge of the first arm 24 is pressed to rotate in the same direction while flexing and deforming the arm 24 upward, and reaches the release position in FIG. Moves forward from the vertical line X. When the finger is released from the operating lever 3 in this state, the operating lever 3 attempts to swing back in the clockwise direction by its own weight. To do so, the cam portion 51 needs to rotate while bending and deforming the arm 24. Therefore, the rotation of the cam portion 51 is prevented by the arm 24 functioning as a stopper, that is, the operation lever 3 is temporarily held at the release position. In addition, the second pressing portion 3 is moved from the state shown in FIG.
By pressing 4, the operation lever 3 can be swung to the holding position. According to the second embodiment, the operation lever 3 can be temporarily held at the release position with a simple structure, and the temporary holding can be released relatively smoothly.

Third Embodiment Next, a third embodiment of the present invention will be described with reference to FIGS. The connector of this embodiment includes a connector housing 60 (hereinafter, simply referred to as a housing), a plurality of terminals 70 attached to the housing 60, and an operation lever 80 rotatably attached to the housing 60. I have. The sheet-like conductive path applied to this embodiment includes:
A ribbon cable 4 made of FPC similar to that exemplified in the first embodiment, which is inserted with the conductive paths facing downward, and a terminal 70 described below at the tip of each conductive path. The contact portion 74 </ b> A that can be contacted.

The housing 60 is, as shown in FIG.
It is formed in a substantially short block shape by synthetic resin material,
On the front surface (the right side in the figure), an insertion opening 61 into which the distal end of the ribbon cable 4 is inserted is opened laterally.
A substantially circular shaft portion 6 is provided at the tip of the upper wall 62 of the insertion port 61.
3 are formed. As shown in FIG. 12, a plurality of slit-shaped cavities 64 are provided in the housing 60.
Are formed side by side in the horizontal direction, and the terminals 70 can be accommodated in the respective cavities 64.

The terminal 70 is, as shown in FIG.
A support portion 71 having a shaft portion 72 formed at a front end, a board mounting portion 73 of a printed wiring board (not shown) protruding downward from a rear end of the support portion 71, and L extending downward from the support portion 71.
And a resilient contact portion 74 extending in a letter shape. Each terminal 70 is inserted into the cavity 64 from behind,
A positioning portion 75 projecting downward from the support portion 71 is housed in a recessed state by fitting into a concave portion 65 formed in the cavity 64.

When the terminal 70 is accommodated in the cavity 64, the support portion 71 is accommodated in the upper wall 62 of the insertion port 61, and the shaft 72 at the tip is connected to the shaft 6 of the housing 60.
3 and coaxially. The elastic contact portion 74 is vertically movably positioned within the slit portion 67 of the lower wall 66 of the insertion port 61, and the contact portion 74 </ b> A at the tip protrudes into the insertion port 61 in a natural state. The board mounting portion 73 protrudes from the rear surface of the housing 60 and can be soldered to a conductive path on the printed wiring board.

The operating lever 80 is made of an insulating material such as a synthetic resin. The operating lever 80 has an arcuate portion 81 fitted to the shaft portion 63 of the housing 60, and the tip of the arcuate portion 81 in the counterclockwise direction in FIG. Plate-shaped lever portion 8 extending tangentially from the edge
And 2. The lever portion 82 has a window hole 83 that fits into a suction portion 68 (used for suction by a suction cup, not shown) protruding from the upper surface of the housing 60.

The operating lever 80 is provided with a pin 84 protruding from both side surfaces on the base end side of the lever portion 82 and a housing 60.
Into the bearing hole 69 formed in the side wall of the
1 is externally fitted to the shaft portions 63 and 72 of the housing 60 and the terminal 70 which are aligned with each other, so as to be reciprocally rotatable between a holding position shown in FIG. 12 and a release position shown in FIG. ing. When the operation lever 80 is at the holding position, the suction portion 68 is fitted into the window hole 83 while the lever portion 8 is being held.
2 overlaps the upper surface of the housing 60. In this state, as shown in FIG.
The (operating end) protrudes rearward from the rear surface on the upper end side of the housing 60, and the lever portion 82 can be easily raised upward by putting a finger on the protruding tip edge 82A. On the other hand, when in the release position, the lever 8
2 rises from the upper surface of the housing 60 and takes a posture obliquely rearward.

At the front end in the clockwise direction in FIG. 11 of the arc-shaped portion 81 of the operation lever 80, a holding projection 86 projecting to the outer peripheral side is formed in the entire width. When the operation lever 80 is in the holding position, the holding ridge 86 projects almost directly downward, and the tip of the holding ridge 86 and the lower wall 66 of the insertion port 61 are inserted.
Is slightly smaller than the thickness of the ribbon cable 4.

Next, the operation of the third embodiment will be described. When the ribbon cable 4 is connected to the housing 60, the leading edge 8 is changed from the state shown in FIGS.
The operation lever 80 is turned to the release position shown in FIG. 13 and FIG. Subsequently, the distal end portion of the ribbon cable 4 is inserted from the front (the right side in FIG.
1, especially the arc-shaped part 81 of the operating lever 80 and the lower wall 66
Insert between.

When the ribbon cable 4 is inserted until the end of the ribbon cable 4 comes into contact with the inner wall 61A of the insertion slot 61, the operation lever 80 is rotated counterclockwise in FIG. 16B to hold it as shown in FIG. Bring to position. Then, since the holding projection 86 of the operation lever 80 faces downward, the ribbon cable 4 is pressed against the lower wall 66 while deforming the elastic contact portion 74 of the terminal 70 downward, and the restoration elasticity of the elastic contact portion 74 is also helped. The distal end of the ribbon cable 4 is held in a state where it cannot be removed. At the same time, the contact portion 74A of the elastic contact portion 74 elastically contacts the conductive path on the lower surface of the ribbon cable 4 to establish conduction.

Here, from the connection state shown in FIG. 16 (C), there is a case where a tensile force acts on the ribbon cable 4 while being bent upward in front of the insertion port 61 as shown by an arrow in FIG. is there. However, since the operation lever 80 overlaps the upper surface of the housing 60 with the front edge 82A of the lever portion 82 facing rearward opposite to the insertion opening 61, the ribbon cable 4 does not contact the lever portion 82. Rather, the operation lever 80 does not rotate to the release position side in order to apply a turning force to the operation lever 80 in the direction of the holding position. Of course, even when the ribbon cable 4 is bent downward, it does not come into contact with the operation lever 80. Therefore, the connection reliability of the ribbon cable 4 is improved. When the operation lever 80 is in the holding position, the housing 6 is turned rearward as described above.
Since it overlaps the upper surface of the connector 0, there is no protrusion from the insertion port 61 forward, and the connector can be combined into a compact connector having a particularly short depth.

<Fourth Embodiment> A fourth embodiment of the present invention will be described with reference to FIGS. The connector of the third embodiment is a lower contact type in which the contact portion 74A of the terminal 70 is arranged on the lower surface side of the insertion opening 61 of the housing 60, whereas the connector of the fourth embodiment is a housing An upper contact type in which the contact portion 104A of the terminal 100 is disposed on the upper surface side of the insertion port 91 of the 90.

To explain again, the connector of the fourth embodiment comprises a housing 90, a plurality of terminals 100 attached to the housing 90, and a housing 9.
And an operation lever 110 rotatably attached to the control lever 110. Contrary to the third embodiment, the ribbon cable 4 is inserted with the conductive path facing upward, and a contact portion 104A described later of the terminal 100 is in contact with the end of each conductive path. It is possible.

Are formed side by side in the lateral direction, and the terminals 100 can be accommodated in the respective cavities 94.

The terminal 100 includes the support portion 71 and the elastic contact portion 7 of the terminal 70 exemplified in the third embodiment.
4 is formed upside down. That is, as shown in FIG. 18, the terminal 100 has a board mounting portion 103 for connecting to a printed wiring board, a front end extending from the lower end of the board mounting portion 103, and a shaft portion 102 at the front end.
And a resilient contact portion 104 extending upward from the support portion 101 in an L-shape. Each terminal 100 is inserted into the cavity 94 from the rear, and the positioning portion 105 projecting upward from the support portion 101 is fitted in a concave portion 95 formed in the cavity 94 to be housed in a retaining state.

When the terminal 100 is accommodated in the cavity 94, the support 101 is attached to the lower wall 9 of the insertion port 91.
2, the shaft 102 at the distal end is coaxially aligned with the shaft 93 of the housing 90. The elastic contact portion 104 is formed by a slit portion 97 of the upper wall 96 (also serving as a suction portion) of the insertion port 91
It is located to be able to move up and down inside, and in the natural state, the contact part 1 at the tip
04A protrudes into the insertion opening 91. The board mounting portion 103 protrudes rearward of the housing 90 and can be soldered to a conductive path on the printed wiring board.

The operation lever 110 is made of an insulating material such as a synthetic resin, and has an arc-shaped portion 111 applied to the outer periphery of the shaft portion 93 of the housing 90, an arm portion 113 rising from both ends of the arc-shaped portion 111, and Plate-shaped lever portion 1 having a flat gate shape formed at right angles from the tips of both arm portions 113
12.

The operation lever 110 is
Pins 114 projecting from both sides on the base end side of the housing 90 are fitted into bearing holes 99 formed in the side wall of the housing 90, and the arc-shaped portion 111 is fitted to the shaft portion 93 where the housing 90 and the terminal 100 are aligned. , 102, the result is shown in FIG.
19 and a release position shown in FIG. When the operation lever 110 is in the holding position, the lever portion 112 overlaps the upper surface of the housing 90 while the upper wall 96 of the insertion port 91 is fitted inside. On the other hand, when it is in the release position, the lever portion 112 rises from the upper surface of the housing 90 and takes a posture obliquely rearward.

The arc-shaped portion 111 of the operation lever 110
21 has a straight portion 1 at the front end in the counterclockwise direction in FIG.
15 is cut, and the remaining arc-shaped portion serves as a holding portion 116. When the operation lever 110 is at the holding position, the holding portion 116 is located at an upper position, and corresponds to the ceiling surface of the insertion port 91 at an interval slightly smaller than the thickness of the ribbon cable 4. When the operation lever 110 is in the release position, the straight portion 115 is located above, and the interval is set to be slightly larger than the thickness of the ribbon cable 4 between the terminal portion 100 and the contact portion 104A.

The operation of the fourth embodiment is as follows.
When the ribbon cable 4 is connected to the housing 90, the operation lever 110 is raised from the state shown in FIG. 18 and FIG. ). Here, the leading edge 112A of the lever portion 112
Is formed so as to protrude from the rear surface of the housing 90 in the same manner as in the third embodiment, a finger is easily hooked on the distal end edge 112A, and the releasing operation is facilitated. Operation lever 110
Is rotated to the release position, the leading end of the ribbon cable 4 is moved from the front (the right side in FIG. 21B) to the insertion opening 91 of the housing 90, in particular, between the arc-shaped portion 111 of the operation lever 110 and the upper wall 96. Insert. In the release position, the straight portion 115
Are located above, and the contact portion 10 of the terminal 100 is
Since there is an interval greater than the thickness of the ribbon cable 4 with the ribbon cable 4A, the ribbon cable 4 is inserted smoothly.

When the end of the ribbon cable 4 is inserted until it comes into contact with the back wall 91A of the insertion port 91, the operation lever 110 is rotated counterclockwise in FIG. 21B to hold it as shown in FIG. Bring to position. Then, since the holding portion 116 of the operation lever 110 is located above, the ribbon cable 4 is pressed against the upper wall 96 while flexing and deforming the elastic contact portion 104 of the terminal 100 upward, and the restoration elasticity of the elastic contact portion 104 is also helped. The distal end of the ribbon cable 4 is held in a state where it cannot be removed. At the same time, the contact portion 104A of the elastic contact portion 104 elastically contacts the conductive path on the upper surface of the ribbon cable 4 to establish conduction.

Here, from the connection state shown in FIG. 21 (C), there is a case where a tensile force acts on the ribbon cable 4 while being bent upward in front of the insertion opening 91 as shown by an arrow in FIG. is there. However, since the operation lever 110 overlaps the upper surface of the housing 90 with the front end edge 112A of the lever portion 112 facing rearward opposite to the insertion opening 91, the ribbon cable 4 does not contact the lever portion 112. Therefore, the operation lever 110 does not rotate toward the release position. Of course, even when the ribbon cable 4 is bent downward, it does not come into contact with the operation lever 110. Therefore, the connection reliability of the ribbon cable 4 is improved. Further, when the operation lever 110 is in the holding position, since the operation lever 110 faces rearward and overlaps the upper surface of the housing 90 as described above, there is no protrusion from the insertion port 91 to the front, and the depth dimension is similarly short and compact. Combined into connectors.
