Japanese Patent Laid-Open No. 2008-4404

  In the connector as described above, when the cable is connected to the connector, after the cable is inserted into the contact body, the operation lever is rotated to the retaining position to press and fix the cable. However, even if the operation lever is rotated to the retaining position, the feeling of operation does not change, so the operator cannot clearly know whether the operating lever is rotated to the retaining position. For this reason, the connector is damaged by trying to rotate the operating lever from the locking position, or the operating lever is not rotated to the locking position because of the risk of damage to the connector, resulting in the cable not being securely fixed to the connector. There was a problem that workability was lowered.

  The present invention has been made in view of the above problems, and its object is to obtain an appropriate click feeling when operating the operation lever to fix the cable, and to connect the cable to the connector. It is to provide a connector with high workability.

  In order to achieve the above object, the invention of claim 1 comprises a connector main body into which a flat cable is inserted into and removed from a contact housing space provided inside through a cable insertion opening opened on the surface, and a conductive material. A plurality of contacts that are disposed inside the contact storage space and sandwich the cable from one side and the other side in the thickness direction and are electrically connected to the cable, and a cable inserted into the contact storage space are relatively It is arranged in the connector main body so as to be rotatable between a removal position that makes it difficult to remove and an insertion position that makes it relatively easy to remove, and at the removal position, the cam portion formed at the end of the connector body And an operation lever for elastically contacting the contacts with the cable by pressing the contacts, and the contacts are stored in the contacts. A fixed portion that is fixed to the inner surface on the one side and that faces the cam portion of the operation lever on the other end surface, and engages the cam portion from the other side to move the operation lever to the other side. And a movable part that is displaced according to the rotation of the cam part, and a support part that swingably supports the movable part with respect to the fixed part, and at least of the plurality of contacts. The fixed portion of any one of the contacts is provided with a spring projection that can be elastically displaced in the thickness direction of the cable and has a run-up projection facing the cam portion. When the lever is rotated from the insertion / extraction position to the prevention position, the ride-up protrusion is pushed down by being pressed by the cam part, and when the operation lever is rotated to the removal position, the cam part is Said Ri is formed so as to resiliently return to a position not pressed down by raising out of the protrusion, characterized by comprising.

  According to the first aspect of the present invention, when the operation lever is rotated from the insertion / extraction position to the removal prevention position, one end of the cam portion of the operation lever is moved over the riding protrusion while elastically displacing the spring protrusion provided on the fixed portion. It has become. Therefore, the operator can obtain an appropriate click feeling when the cam portion has climbed over the protruding protrusion, and can easily recognize that the operation lever has been rotated to the retaining position. Also, since the climbing protrusion is provided on a spring projection that can be elastically displaced, the cam lever is pushed up by the climbing protrusion when the cam is over the climbing protrusion and the operation lever becomes unstable. The operation lever can be stably operated.

  According to a second aspect of the present invention, in the connector according to the first aspect, a spring protrusion having the riding protrusion is provided on all of the plurality of contacts.

  In the invention of claim 2, ride-up protrusions are provided on all the contacts. Therefore, the operator can obtain a large click feeling when the cam portion has climbed over the protruding protrusion, and can reliably recognize that the operation lever has been rotated to the retaining position.

  According to a third aspect of the present invention, in the connector according to the first or second aspect, the cable is made of a conductive material, and is alternately arranged in parallel with the contacts in the contact accommodating space, so that the cable is connected to one side and the other side in the thickness direction. The second contact is sandwiched from the side and electrically connected to the cable at a contact position different from the contact, and the second contact is fixed to the inner surface on one side of the contact storage space. A second movable portion that engages with the cam portion of the operation lever from one side to restrict movement of the operation lever to the one side, and is displaced in accordance with the rotation of the cam portion. And a second support part that swingably supports the second movable part with respect to the second fixed part, wherein the operating lever includes the cam part and the movable part. 2 moving parts By the square side and one side is elastically sandwiched, characterized by comprising a rotatably held with respect to the connector body.

  According to invention of Claim 3, since the said contact and the 2nd contact from which the said contact differs in a contact position are arranged in parallel, each contact can be arrange | positioned by a narrow space | interval and a connector Can be miniaturized. In addition, since the movable portion and the second movable portion hold the cam portion of the operation lever, the operation lever can be held without providing the connector body with a bearing structure for the operation lever.

  The present invention can provide an appropriate click feeling when operating the operation lever to fix the cable, and can provide a connector with high workability when connecting the cable to the connector.

The first contact 3 is formed in an H shape by a fixed portion 31, a movable portion 32, and a support portion 33, and is inserted into each storage chamber from the opening 22 side.

  The fixing portion 31 of the first contact 3 is disposed in the contact storage space 20 with the lower edge abutting against the inner surface (upper surface of the lower wall) of the connector main body 2. A claw 31a projects from the distal end of the fixed portion 31 on the cable insertion port 21 side toward the movable portion 32 side. Further, the end of the fixing portion 31 on the opening 22 side extends downward from a notch 2a provided on the lower wall of the connector body 2 and is soldered to a conductor pattern provided on a mounting board (not shown). A terminal piece 34 is provided. A spring protrusion 35 that protrudes from the upper portion of the terminal piece 34 toward the support portion 33 is provided in front of the support portion 33 (left side in FIG. 1) in the fixed portion 31. A gap is formed between the tip of the spring projection 35 and the fixing portion 31 in a state where no load is applied to the spring projection 35, and the tip of the spring projection 35 can be elastically displaced in the vertical direction. It has become. Further, the front end of the spring projection 35 faces a cam 51 of the operation lever 5 to be described later, and when the cam 51 is rotated, the cam 51 can ride on and is a gentle mountain shape. A riding protrusion 35a is provided so as to protrude.

  The movable portion 32 of the first contact 3 has a claw 32a projecting from the distal end portion on the cable insertion port 21 side toward the fixed portion 31 side, and the claw 31a on the fixed portion 31 side and the movable portion 32 side. The claw 32a sandwiches the cable 100 inserted between the fixed portion 31 and the movable portion 32. Further, in the movable portion 32, a semicircular concave portion 36 into which a cam portion 51 of the operation lever 5 described later is fitted is formed on the lower surface of the portion that is in front of the portion supported by the support portion 33 (left side in FIG. 1). The movable portion 32 restricts the movement of the operation lever 5 to the upper side (the other side).

  On the other hand, as shown in FIGS. 2 (a) and 2 (b), the odd-numbered second contacts 4 are disposed in the contact storage space 20 so as to face each other along the cable insertion direction (front-rear direction). The fixed portion 41 and the movable portion 42 that sandwich the cable 100 inserted into the cable from the lower side (one side) and the upper side (the other side), and the fixed portion on the front end side (left side in FIG. 2) of the fixed portion 41 and the movable portion 42 And a support portion 43 that swingably supports the movable portion 42 with respect to 41. The second contact 4 is formed in a U shape by the fixed portion 41, the movable portion 42, and the support portion 43, and is inserted into each storage chamber from the cable insertion port 21 with the support portion 43 as the head.

  The fixing portion 41 of the second contact 4 is disposed in the contact storage space 20 with the lower edge abutting against the inner surface (upper surface of the lower wall) of the connector main body 2. A terminal that extends downward from a notch 2b provided on the lower wall of the connector main body 2 and is soldered to a conductor pattern provided on a mounting board (not shown) at the end of the fixing portion 41 on the cable insertion port 21 side. A piece 44 is provided. Further, an elastic contact piece 45 is provided from the intermediate portion of the fixed portion 41 so as to protrude toward the cable insertion port 21 and the front end portion is opposed to the front end portion of the movable portion 42. A claw 45a protrudes toward the movable part 42 side.

  On the upper side of the movable portion 42 of the second contact 4, a concave portion 46 is provided in a portion exposed from the opening portion 22, and a cam portion 51 of an operation lever 5 described later is inserted into the concave portion 46. The movement of the operation lever 5 to the lower side (one side) is restricted by the portion 42. Further, a claw 42 a is projected from the tip of the movable portion 42 at a portion facing the claw 45 a at the tip of the elastic contact piece 45 toward the elastic contact piece 45. That is, the claw 45a on the fixed portion 41 side and the claw 42a on the movable portion 42 side sandwich the cable 100 inserted between the fixed portion 41 and the movable portion 42.

  The operation lever 5 is formed of an insulating synthetic resin in the shape of a long and narrow plate in the left-right direction, and the cam portions 51 and 52 provided on one end side in the width direction (vertical direction in FIG. 4B) are the rotation centers. As described above, the connector main body 2 is rotatably held between a removal-preventing position that makes the cable 100 relatively difficult to remove and an insertion-extraction position that makes the cable 100 relatively easy to remove.

  The cam part 51 includes a cylindrical part 51a having a circumference of about three quarters and a rectangular parallelepiped part 51b protruding from the cylindrical part 51a. The cam part 51a is provided so that the axial direction of the cylindrical part 51a is aligned in the left-right direction. The movable portion 32 is positioned in the gap portion 53 of the lever 5 and is disposed in a state where the circumferential surface of the cylindrical portion 51 a is in contact with the concave portion 36 of the first contact 3. When the operation lever 5 is rotated, the distance from the lower wall of the connector body 2 to the upper end position of the cam portion 51 changes according to the operation of the operation lever 5, and the operation lever 5 is moved as shown in FIG. The distance from the lower wall of the connector body 2 to the upper end position of the cam portion 51 is maximized in the tilted state (extraction position), and the connector is in the raised state (insertion / extraction position) as shown in FIG. The distance from the lower wall of the main body 2 to the upper end position of the cam portion 51 is minimized. Further, the rectangular parallelepiped portion 51b has such a length that the spring projection 35 can be pushed down when the operation lever 5 is rotated from the raised state (insertion / extraction position) to the tilted state (prevention position). As shown in (b), in a state where the operation lever 5 is tilted (prevention position), the spring protrusion 35 is detached and no downward load is applied to the spring protrusion 35.

  The cam portion 52 is provided corresponding to the concave portion 46 of the second contact 4 and has a rectangular cross-sectional shape. When the operation lever 5 is rotated, the distance from the lower wall of the connector body 2 to the lower end position of the cam portion 52 changes according to the operation of the operation lever 5, and the operation lever 5 is moved as shown in FIG. The distance from the lower wall of the connector body 2 to the lower end position of the cam portion 52 is minimized in the tilted state (extraction position), and the connector is in the raised state (insertion / extraction position) as shown in FIG. The distance from the lower wall of the main body 2 to the lower end position of the cam portion 52 is maximized.

  As described above, in the present embodiment, the cam portions 51 and 52 of the operation lever 5 are provided corresponding to the movable portions 32 and 42 of the contacts 3 and 4 of the plurality of poles, respectively, and the first contacts 3 of even pins. The movable portion 32 presses the cam portion 51 downward, and the movable portion 42 of the odd-numbered second contact 4 presses the cam portion 52 upward, so that the operation lever 5 is pivoted on the connector body 2. Even without providing a supporting bearing structure, the operation lever 5 can be pivotally supported by the respective contacts 3 and 4 held by the connector main body 2.

  Here, the operation | movement at the time of fixing the cable 100 to the connector 1 of this embodiment is demonstrated.

  Before connecting the cable 100, as shown in FIGS. 1 (a), 2 (a), and 3, the position where the operation lever 5 stands upright (the position substantially orthogonal to the fixing portions 31, 41 of the contacts 3, 4). In this state, the cam portion 51 does not press the concave portion 36 of the first contact 3 upward, so that the elastic deformation of the movable portion 32 does not occur, and the claw 32a of the movable portion 32 is fixed to the fixed portion 31. It is displaced in the direction away from the claw 31a (upper side). In this state, the cam portion 52 does not press the concave portion 46 of the second contact 4 downward, so that the elastic deformation of the movable portion 42 does not occur, and the claw 42 a of the movable portion 42 It is displaced in the direction away from the claw 45a (upper side). Therefore, when the operation lever 5 is rotated to the insertion / extraction position shown in FIGS. 1A and 2A, the claws 32 a and 42 a of the movable portions 32 and 42 are displaced to a position where they do not contact the cable 100. Therefore, the resistance when the cable 100 is plugged into the connector 1 can be reduced, and a soft cable 100 such as an FPC can be easily plugged into the connector 1. It should be noted that the claws 32a and 42a of the contacts 3 and 4 may be disposed at a position where the operation lever 5 is rotated to the insertion / extraction position. Connection is established, but the holding force for holding the cable 100 by each of the contacts 3 and 4 is relatively small compared to the case where the operation lever 5 is in the retaining position. It is in a state where it is relatively easy to come off.

  When the cable 100 is inserted into the connector main body 2 from the cable insertion port 21 with the operation lever 5 rotated to the insertion / extraction position, the upper and lower surfaces of the cable 100 are guided by the guide grooves 24 provided in the partition wall 23. The cable 100 is inserted between the fixed portions 31 and 41 and the movable portions 32 and 42 of the contacts 3 and 4.

  From the state in which the cable 100 is inserted into the connector main body 2, the operation lever 5 is rotated counterclockwise as viewed in FIGS. 1, 2, and 3 (c) with the cam portion 51 and the cam portion 52 as the rotation center. . When the operation lever 5 is rotated, the rectangular parallelepiped portion 51b of the cam portion 51 comes into contact with the front side (left side in FIG. 1) of the riding projection 35a of the spring projection 35, and then pushes down the spring projection 35 downward. When the operation lever 5 rotates over the riding protrusion 35a and rotates to the retaining position, it reaches the rear side (right side in FIG. 1) of the riding portion 35a (FIG. 1 (b)). The behavior of the spring projection 35 at this time is pushed downward most when the rectangular parallelepiped portion 51b is riding over the riding projection 35a, and the rectangular parallelepiped portion 51b finishes overcoming the riding projection 35a, and the riding projection When it comes off from 35a and reaches the rear side of the spring projection 35, it returns elastically upward. In this way, the cam portion 51 rotates while getting over the riding protrusion 35a, so that the operator can obtain an appropriate click feeling when the cam portion 51 finishes getting over the riding protrusion 35a. Further, when the cam portion 51 gets over the riding protrusion 35a, the spring protruding portion 35 is pushed down, so that, for example, when the riding protrusion is provided directly on the fixed portion 31, The possibility that the cam portion 51 itself is pushed upward by the riding protrusion is small, and the operation lever 5 can be operated stably. In addition, as long as operation does not become unstable, the structure by which the cam part 51 is pushed up by the riding protrusion 35a may be sufficient.

  When the operation lever 5 is rotated to the retaining position shown in FIGS. 1B, 2 </ b> B, and 4, the cam portion 51 presses the concave portion 36 of the first contact 3 upward to move the movable portion 32. The claw 32a of the movable part 32 is displaced toward the fixed part 31 with the support part 33 as a fulcrum, and the claw 32a of the movable part 32 is elastically contacted with the conductor pattern 101 provided on the upper surface of the cable 100. Yes. At this time, the cam portion 52 presses the concave portion 46 of the second contact 4 downward to elastically deform the movable portion 42, whereby the claw 42a of the movable portion 42 is displaced to the elastic contact piece 45 side (lower side). Thus, the claw 42 a of the movable portion 42 is in elastic contact with the conductor pattern 101 provided on the upper surface of the cable 100. Therefore, at this time, since the claws 32a and 42a of the movable parts 32 and 42 are pressed against the cable 100, the cable 100 is held by the contact pressure of the contacts 3 and 4, and the cable 100 is relatively difficult to come off. It becomes a state. In addition, the cable 100 is sandwiched between the claw 32a of the movable portion 32 and the claw 31a of the fixed portion 31, and the cable 100 is sandwiched between the claw 42a of the movable portion 42 and the claw 45a of the elastic contact piece 45. As a result, the contacts 3 and 4 and the conductor pattern 101 of the cable 100 are electrically connected.

  On the other hand, when the operation lever 5 is rotated from the removal prevention position to the insertion / removal position in a state where the cable 100 is connected to the connector 1, the force by which the cam portions 51 and 52 press the concave portions 36 and 46 of the contacts 3 and 4 is generated. The claw 32a, 42a of the movable part 32, 42 is displaced upward by the spring restoring force of the movable part 32, 42 and away from the cable 100, so that each contact 3, 4 has no force to hold the cable 100, The cable 100 can be easily pulled out. In the present embodiment, even when the operation lever 5 is rotated from the removal prevention position to the insertion / removal position, the cam portion 51 rotates while getting over the riding protrusion 35a, so that an appropriate click feeling can be obtained. Yes.

  The connector 1 of the present embodiment has the above-described configuration. When the operation lever 5 is rotated from the insertion / extraction position to the removal prevention position, the rectangular parallelepiped portion 51b of the cam portion 51 rides while pushing down the spring protrusion 35. The spring protrusion 35 returns elastically when it has climbed over the protrusion 35a and over the ride-up protrusion 35a. Therefore, when the cam portion 51 finishes over the riding protrusion 35a, an appropriate click feeling can be obtained, and it can be easily recognized that the operation lever 5 has been rotated to the retaining position, thereby obtaining a connector with high workability. be able to.

  In this embodiment, the conductor pattern 101 provided on the upper surface of the cable 100 and the claws 32a and 42a provided on the movable parts 32 and 42 are in electrical contact with each other, but on the fixed parts 31 and 41 side. The provided claws 31 a and 45 a may be in electrical contact with the conductor pattern provided on the lower surface of the cable 100.

  Further, as the contact disposed in the contact storage space 20, only the first contact 3 may be used without using the second contact 4, and the connector body 2 may be provided with a bearing structure for the operation lever 5.

  Further, it is not always necessary to provide the spring protrusions 35 on all the first contacts 3, and if a sufficient click feeling can be obtained when the operation lever 5 is rotated to the retaining position, the plurality of first contacts 3 are provided. Only one of them may be provided with the spring projection 35.
