Description

  The present invention relates to a connector that is connected to a connection object such as an FPC, FFC, or a rigid board, and more particularly to a structure that securely connects the connection object and the connector.

  A conventional FPC connector will be described (see, for example, Patent Document 1).

  As shown in FIG. 3, the housing 61 of the connector 60 has a flat box shape and includes a bottom plate portion 62, an upper plate portion 63, a side plate portion, and a back plate portion 66. The housing 61 has a flat rectangular frame portion 67 on the left side, and the rectangular frame portion 67 forms an insertion port 68 of the FPC 40. A rectangular opening 69 corresponding to the actuator 80 is formed in the upper plate portion 63.

  The contact 70 includes a base portion 71, an upper beam 72, and a lower beam 73. The base portion 71 has an external terminal portion 74 on the lower right side and a semicircular support portion 75 on the upper left side. A column portion 76 is formed on the upper left side of the base portion 71. The upper beam 72 has a wide root portion 77, and the root portion 77 is continuous with the column portion 76. The column portion 76 is constricted and is configured to be easily elastically deformed on the left side. A stopper portion 78 is formed at the base portion 77 of the upper beam 72 toward the lower beam 73. A gap g exists between the stopper portion 78 and the lower beam 73. The upper beam 72 and the lower beam 73 have contacts 72a and 73a at their tips, respectively.

  The contact 70 is integrally formed in a substantially U shape, and the distance between the contacts 72a and 73a is larger than the sum of the thicknesses of the FPC 40 and the reinforcing plate 45 attached thereto.

  The base portion 71 of the contact 70 is fixed to the hole 66 a of the back plate portion 66. The upper and lower side beams 72 and 73 are accommodated in the housing 61, and the contacts 72 a and 73 a face the insertion opening 68 of the FPC 40. The tip side of the lower beam 73 is separated from the upper surface of the bottom plate portion 62 so that the lower beam 73 can be elastically deformed. The root portion 77 faces the support portion 75.

  The actuator 80 includes a quadrangular cover portion 81 corresponding to the rectangular opening 69, and a push-out plate portion 82 that is inclined and extends from the cover portion 81. The push-out plate portion 82 has a cam portion 83. The cam portion 83 is formed with a bearing portion 84 corresponding to the support portion 75.

  The bearing portion 84 of the actuator 80 fits in the support portion 75, and the cam portion 83 enters between the support portion 75 and the root portion 77.

  An operation for connecting the FPC 40 to the connector 60 will be described. First, the actuator 80 is pulled up to the position of FIG. 3, and the FPC 40 is inserted into the connector 60 until the tip of the FPC 40 abuts against the stopper portion 78. Next, the actuator 80 is pushed down to the position shown in FIG. Then, the actuator 80 rotates using the support portion 75 as a fulcrum, and at this time, the cam portion 83 applies a force F10 to the root portion 77. Accordingly, the column portion 76 is elastically deformed in the left direction, and the contact point 72a is displaced in the downward direction. The column portion 76 is elastically deformed until the tip of the stopper portion 78 comes into contact with the root portion of the lower beam 73.

  When the contact 72a is displaced downward, both the contacts 72a and 73a abut against the FPC 40, and further displacement is limited. The column portion 76 is elastically deformed thereafter, and in this process, the upper and lower side beams 72 and 73 are elastically deformed.

  Then, both the contacts 72a and 73a give the FPC 40 a contact pressure of force F11. Therefore, the conductor pattern 41 of the FPC 40 is connected to the contact 73 a of the connector 60.

JP 2004-39479 A (page 7, line 3, to page 9, line 23, FIGS. 4 and 5)

  In the conventional connector 60, the cam portion 83 of the actuator 80 pushes the root portion 77 of the contact 70, the column portion 76 is elastically deformed, and the tip of the stopper portion 78 abuts against the root portion of the lower beam 73. is there.

  Therefore, the conventional connector 60 has a complicated structure and is difficult to make a stable connection with the FPC 40.

  Therefore, the present invention aims to provide a connector that improves the drawbacks of the connector, has a simple structure, and can stably connect to a connection object such as an FPC.

  The present invention employs the following means in order to solve the above problems.

1. In the connector to be connected to the connection object, the connector is movable between a contact to be connected to the connection object, a housing for holding the contact, and a connection position and a non-connection position of the connection object. An operating member held in a housing, the operating member has a cam portion, and the contact is opposed to the first spring portion, the first spring portion having a first projecting portion, and the first spring portion. And a second spring part having a second projecting part, the second spring part having a recess for engaging with the cam part, and the first projecting part and the second projecting part. Both of the protruding portions elastically contact with both surfaces of the connection object, respectively, and one of the protrusions is electrically connected to one surface of the connection object, and when connecting to the connection object, the cam portion and the first And a base end portion of the spring portion of the connection object, Connectors for holding the vicinity of.

  2. The connector according to claim 1, wherein the first projecting portion and the second projecting portion are disposed so as to be shifted in a fitting / removing direction with respect to the connection object.

  As is apparent from the description of the specification, the present invention has the following effects.

  1. The structure is simple, and stable connection with a connection object such as an FPC can be reliably performed.

  2. The operating member can connect and disconnect the connection object and the connector by either a rotational motion or a linear motion such as a slide.

  3. Since the first projecting portion and the second projecting portion of the contact are arranged so as to be shifted in the fitting / removing direction with respect to the connection object, it is easy to insert and remove the connection object with respect to the connector.

  A connector according to an embodiment of the present invention will be described.

  The FPC connector according to Embodiment 1 of the present invention will be described with reference to FIGS.

  In FIG. 1 showing a state before the FPC 11 is fitted to the connector 1, a large number of contacts 2 are held by the insulator 3 at a constant pitch in a direction perpendicular to the paper surface. An actuator 4 is supported on the insulator 3 so as to be able to rotate 90 ° about a cam portion 4 a provided on the actuator 4.

  Each contact 2 includes a base portion 2a, an elastically deformable upper beam 2b continuous with the base portion 2a, an elastically deformable lower beam 2c continuous with the base portion 2a, and a fixing terminal continuous with the base portion 2a. The portion 2d is integrally formed in a substantially U shape.

  The lower beam 2c is set longer than the upper beam 2b. A contact 2b1 is formed at the tip of the upper beam 2b so as to protrude, and a contact 2c1 is formed at the tip of the lower beam 2c. The distance between the contact 2b1 and the contact 2c1 in the vertical direction is set slightly smaller than the thickness of the FPC 11. The lower beam 2c adjacent to the base portion 2a is formed with a recess 2c2 for engaging the cam portion 4a.

  The FPC 11 needs to have rigidity capable of withstanding bending stress caused by pressure contact with each contact 2. A metal plate 11a and the like whose surface is insulated from the surface of the contact 2 opposite to the surface of the FPC 11 that contacts the contact 2c1 are fixed for reinforcement.

  An operation when the FPC 11 is connected to the connector 1 will be described. In the state before the mating shown in FIG. 1, each contact between the upper beam 2 b and the lower beam 2 c of each contact 2 is indicated by a broken line at the mating side end portion of the FPC 11 indicated by a solid line. Insert to the end of 2. When the FPC 11 is inserted in a posture slightly inclined with respect to the connector 1, it can be inserted with a smaller force than that in a parallel posture. Further, since the contact 2b1 and the contact 2c1 are arranged so as to be displaced in the fitting / removing direction of the FPC 11 with respect to the connector 1, it is easy to insert and remove.

  After the fitting side end of the FPC 11 is inserted to the position indicated by the broken line in FIG. 2, the actuator 4 is rotated about 90 ° in the direction of the arrow A from the position of the two-dot chain line about the cam portion 4a. Bring to position. Then, the cam portion 4a pushes the vicinity of the fitting side end portion of the FPC 11 and rotates it by a slight angle in the direction of arrow B from the position of the broken line to reach the position of the solid line. At this time, the metal plate (the surface is insulated) 11a fixed to the upper surface of the FPC 11 is in pressure contact with the upper beam 2b of each contact 2, and a conductor pattern (not shown) formed on the lower surface of the FPC 11. ) Contacts the contact 2c1 of each contact 2. The vicinity of the fitting side end portion of the FPC 11 is sandwiched between the cam portion 4a and the root portion of the upper beam 2b. Therefore, the FPC 11 slightly enlarges between each upper beam 2b and each lower beam 2c, and a contact force is generated between each contact 2c1 and the conductor pattern of the FPC 11. Therefore, the connection between the FPC 11 and the connector 1 is completed.

  In addition, since the FPC 11 is sandwiched between the cam portion 4a and the base portion of the upper beam 2b, the FPC 11 is hardly pulled out, and the holding force of the FPC 11 is improved.

  In the first embodiment, the actuator 4 performs a rotational motion, but the design can be changed to perform a linear motion such as a slide.

  In addition, a reinforcing metal plate 11 a whose surface is insulated is fixed to one surface of the FPC 11, but the design is changed so that the metal plate 11 is fixed only to a required portion on one surface or both surfaces of the FPC 11. can do.
