Description

  The present invention relates to a connector that connects to an object to be connected such as an FPC, FFC, or a rigid substrate. More specifically, the present invention relates to a connector that contacts arranged in a plurality of rows reliably connect to an object to be connected.

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

  3 is a cross-sectional view showing a state in which the two FPCs 70 and 80 are not yet fitted into the FPC connector 21, and FIG. 4 is a cross-sectional view showing the fitted state.

  The FPC connector 21 includes a housing (insulator) 30, a first contact (upper contact) 40, a second contact (lower contact) 50, and an actuator 60.

  The housing 30 is configured in a substantially rectangular parallelepiped shape, and two FPC insertion ports 31 and 32 are provided on the front surface thereof, and an opening 33 is provided on the upper surface thereof.

  The first contact 40 includes a support portion 41 that rotatably supports the actuator 60, a spring portion 42 that contacts a conductive pattern (not shown) of the first FPC 70, a protrusion 43 that presses the second FPC 80, and the housing 30. And a press-fit portion 44 that is press-fit into the hole 34.

  The front end portion 41a of the support portion 41 is formed in a bowl shape.

  A contact portion 42a is formed at the tip of the spring portion 42 so as to be elastically deformable in the vertical direction.

  The contact portion 42a of the first contact 40 faces the actuator 60 in the up-down direction. The first FPC 70 inserted into the FPC insertion port 31 is located between the actuator 60 and the contact portion 42a.

  On the spring portion 42, a protrusion 43 is formed integrally with the contact portion 42a.

  The second contact 50 includes a spring portion 51 that contacts a conductor pattern (not shown) of the second FPC 80 and a press-fit portion 52 that is press-fitted into the hole 35 of the housing 30.

  A contact portion 51a is formed at the tip of the spring portion 51 so as to be elastically deformable in the vertical direction.

  The contact portion 51a of the second contact 50 faces the protrusion 43 in the up-down direction. The second FPC 80 inserted into the FPC insertion port 32 is located between the protrusion 43 and the contact portion 51a.

  A groove 62 is formed along the longitudinal direction of the actuator 60, and the groove 62 is rotatably supported by the distal end portion 41 a of the support portion 41 of the first contact 40.

  The mounting of the first FPC 70 and the second FPC 80 to the connector 21 will be described.

  First, the groove 62 of the actuator 60 is engaged with the distal end portion 41 a of the support portion 41.

  Next, the first FPC 70 and the second FPC 80 are inserted into the FPC insertion ports 31 and 32, respectively. As a result, the first FPC 70, the contact portion 42a, the second FPC 80, and the contact portion 51a are alternately arranged in the vertical direction. At this time, the conductor pattern of the first FPC 70 contacts the contact portion 42 a of the first contact 40. Further, the conductor pattern of the second FPC 80 is in contact with the contact portion 51 a of the second contact 50.

  Thereafter, the actuator 60 is rotated counterclockwise around the contact point between the groove 62 of the actuator 60 and the tip 41a of the support portion 41 as a rotation center. Then, the flat pressing portion 61 of the actuator 60 presses the first FPC 70 and pushes it down.

  As a result, the contact portion 42 a of the first contact 40 is pressed against the conductor pattern of the first FPC 70 by the elastic force of the spring portion 42.

  At this time, the spring portion 42 is displaced downward, and the protrusion 43 pushes down the second FPC 80.

  As a result, the contact portion 51 a of the second contact 50 is pressed against the conductor pattern of the second FPC 80 by the protrusion 43 of the spring portion 42.

  At this time, the opening 33 of the housing 30 is closed by the actuator 60.

JP-A-2000-119393 (second page, second column, line 42 to third page, fourth column, line 46, FIGS. 1 to 3)

  In the conventional FPC connector, two FPCs and contacts arranged in two rows on the housing are connected and separated by one actuator. Therefore, this connector has an advantage that only one actuator is used as an operation member, but has a disadvantage that it is difficult to reliably perform contact and separation.

  Accordingly, the present invention provides a connector that improves the drawbacks of the conventional FPC connector and can reliably connect and disconnect a connection object such as an FPC and contacts arranged in a plurality of rows on the housing. It is what.

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

In the connector to be connected to the connection object, the connector rotates between a plurality of contacts to be connected to the connection object, a housing for holding each contact, and a connection position and a non-connection position of the connection object. A plurality of operation members held by the housing, each operation member having a cam portion and a rotation shaft, and each contact having a contact point connected to the connection object. A deformable one side beam, and another side beam that is opposed to the one side beam and includes a concave portion that engages with a rotation shaft of each operation member, and the contact of each contact is the connection object A plurality of rows are arranged in a fitting / removing direction with respect to an object, and each of the operation members corresponds to a contact of each contact of the plurality of rows, and contacts and separates the contact of each contact and the connection object for each row. The plurality of operation units Comprises a first operating member and the second operating member, having said first operating member recesses, when the connection object is fitted with the connector, the recess overlapping the second operating member connector .

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

  1. The plurality of operation members respectively correspond to the contacts of the contacts in a plurality of rows, and the contacts of the contacts and the connection object can be reliably connected for each row.

  2. Since the connector includes a plurality of contacts, a housing, and a plurality of operation members, the number of parts is small, the structure is simple, and the cost is low.

  3. Since the rotation shaft of each operation member is held by the housing and engaged with and supported by the concave portion of each contact, each operation member can rotate stably.

  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.

  FIG. 1A shows the first contact 3 in the first row held mainly by the insulator (housing) 2 and the shaft 4 a held by the insulator 2 before the FPC 11 is fitted into the connector 1. It is sectional drawing which shows the 1st actuator (1st operation member) 4 which is present.

  A shaft 4 a provided on the first actuator 4 engages with the recess 3 c 1 of each first contact 3.

  FIG. 1B shows a second row of second contacts 5 mainly held by the insulator 2 and a second state where the shaft 6a is held by the insulator 2 before the FPC 11 is fitted to the connector 1. It is sectional drawing which shows the actuator (2nd operation member) 6. FIG.

  Each second contact 5 is integrally formed in a substantially U shape from a base portion 5a, an elastically deformable lower beam 5b, an upper beam 5c facing the lower beam 5b, and a fixing terminal portion 5d. The

  A contact 5b1 is formed at the tip of each lower beam 5b so as to protrude. A concave portion 5c1 is formed at the tip of each upper beam 5c.

  A shaft 6 a provided in the second actuator 6 engages with the recess 5 c 1 of each second contact 5.

  The contacts 3 b 1 of the first contacts 3 and the contacts 5 b 1 of the second contacts 5 are arranged in a staggered manner in the insulator 2.

  The fitting between the FPC 11 and the connector 1 will be described.

  First, in the state of FIG. 1, the FPC 11 is inserted into the connector 1.

  Next, in the state of FIG. 1B, when the second actuator 6 is rotated about 90 ° counterclockwise about the axis 6a, the second actuator 6 reaches the state of FIG. In this state, the cam portion 6 b of the second actuator 6 presses the FPC 11 downward, so that the conductive pattern (not shown) of the FPC 11 is connected to the contact 5 b 1 of each second contact 5. However, the thickness of the FPC 11 is described as being larger than the actual thickness. At this time, the concave portion 5 c 1 of each second contact 5 serves as a bearing that supports the shaft 6 a of the second actuator 6.

In this state, the cam portion 4 b of the first actuator 4 presses the FPC 11 downward, so that the conductive pattern (not shown) of the FPC 11 is connected to the contact 3 b 1 of each first contact 3. However, the thickness of the FPC 11 is described as being larger than the actual thickness. At this time, the recess 3 c 1 of each first contact 3 serves as a bearing that supports the shaft 4 a of the first actuator 4.

In this manner, each first contact 3 in the first row and each second contact 5 in the second row are connected to the conductive pattern of the FPC 11, so that the FPC 11 is fitted with the connector 1. At this time, since the first actuator 4 has the recess 4 c, the recess 4 c overlaps with the second actuator 6 when the FPC 11 is fitted to the connector 1.

  In the first embodiment, the number of contact rows is two and the number of actuators is two. However, the addition of three or more contact rows and three or more actuators is optional in design.
