Description

  The present invention relates to a connector connected to a connection object such as an FPC (flexible printed circuit), FFC (flexible flat cable), and more specifically, two rows of contacts arranged in a staggered manner. It is related with the connector which has.

  First, the main points of the first conventional FPC connector will be described (for example, see Patent Document 1).

  A number of first contacts are arranged in a row on the housing of the connector, and a number of second contacts are arranged in a row. The first contacts and the second contacts are arranged in a staggered manner. Each first contact is disposed near the entrance where the FPC fits into the connector housing, and each second contact is disposed slightly away from the entrance.

  Each of the first contacts and the second contacts has a ZIF (zero insertion force) structure.

  Therefore, after the FPC is inserted into the connector, the contact portion of each first contact and the contact portion of each second contact are changed to a signal pattern formed on the surface of the FPC by operating an actuator (operation member). The FPC and the connector are connected by pressure welding.

  Next, the main points of the second conventional FPC connector will be described (for example, see Patent Documents 2 and 3).

  The second conventional FPC connector is different from the first conventional FPC connector in that each second contact has a NON-ZIF structure, and the other points are the same.

  The first conventional FPC connector has an advantage that the FPC can be easily inserted into the connector housing. However, since the actuator operates each first contact and each second contact, the structure of the connector is complicated, a large force is required for the operation, and the actuator is required to be robust. Have.

  The second conventional FPC connector has the advantages that the structure is simple, that a large force is not required for operation, and that the actuator is not required to be robust. However, since the second contact has a NON-ZIF structure, the distance from the fitting start position of the FPC to the connector to the peak position of the insertion force (see L2 in FIG. 4) is long. Therefore, this connector is likely to buckle when the FPC is inserted.

  Therefore, the present invention improves the second conventional FPC connector, is unlikely to buckle when inserted into a connector of a connection object such as an FPC, has a simple structure, and does not require a large force for operation. In addition, an object is to provide a connector that does not require robustness in the actuator.

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

  1. The connector 1 includes a first contact 3 and a second contact 4 that are connected to the connection object 6, a housing 2 that holds the first contact and the second contact, and a connection position between the connection object and the connection object. An operating member 5 held by the housing so as to be movable between positions, and the first contact has an elastically deformable beam portion 3a in which a contact portion 3a1 is formed, and the connection In the fitting direction of the object to the connector, the contact portion of the first contact is disposed close to the inlet of the fitting portion 2a of the connector, and the contact portion 4a1 of the second contact is the fitting portion of the connector. When connecting to the connection object, the contact part of the first contact is connected to the connection object by elastically displacing the beam part when connected to the connection object. The connector to be connected to the connection object is displaced by operating the operation member.

  2. The first contact has a second beam portion 3e facing the beam portion, the second beam portion has a contact portion 3e1 at a position facing the contact portion of the first contact, and the connection object The connector according to 1, wherein the first contact is sandwiched between the contact portion and the contact portion.

  3. 2. The connector according to 1, wherein a contact portion 2b is formed in the housing, and the connection object is sandwiched between the contact portion of the first contact and the contact portion.

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

  1. In the fitting direction of the connection object to the connector, the contact portion of the first contact is disposed close to the inlet of the fitting portion of the connector, and the contact portion of the second contact is disposed far from the inlet of the fitting portion, When connecting to the connection object, the contact portion of the first contact is displaced by deformation of the beam portion and connected to the connection object, and the contact portion of the second contact is displaced by operating the operation member. To connect to the connection object. Therefore, buckling is unlikely to occur when the connection object is inserted into the connector.

  2. It is possible to provide a connector that is simple in structure, does not require a large force for operation, and does not require robustness in the actuator.

  The FPC connector according to four embodiments of the present invention will be described.

  A first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a cross-sectional view of the FPC connector 1. A number of first contacts 3 and a number of second contacts 4 are fixed to the housing 2 at a constant pitch in a direction perpendicular to the paper surface. The first contacts 3 and the second contacts 4 are arranged in a staggered manner. An actuator 5 is rotatably attached to the housing 2. Further, the housing 2 is provided with a fitting portion 2a into which the FPC 6 (see FIG. 2) is inserted.

  The first contact 3 has an upper beam portion 3a, a lower beam portion 3b, a fixing portion 3c to the housing 2, and a soldering portion 3d to the substrate. The contact portion 3a1 is formed on the upper beam portion 3a so as to protrude, and the contact portion 3b1 is formed on the lower beam portion 3b.

  FIG. 2 shows a state where the FPC 6 is inserted in the direction of the arrow in the fitting portion 2a of the FPC connector 1 shown in FIG. 1, and the actuator 5 is rotated clockwise and closed. The contact portion 3a1 of the first contact 3 is in contact with a signal pattern (not shown) on the upper surface of the FPC 6, and the contact portion 3b1 is in contact with the lower surface of the FPC 6. The upper beam portion 3a and the lower beam portion 3b can be elastically deformed.

  FIG. 3 is a cross-sectional view showing the relationship among the second contact 4, the actuator 5, and the FPC 6 in the state of FIG.

  The second contact 4 includes a beam portion 4a, an operated portion 4b extending from the beam portion 4a, a connecting portion 4c orthogonal to the middle between the beam portion 4a and the operated portion 4b, an orthogonal to the connecting portion 4c, and the housing 2 4d, and a soldering portion 4e that is orthogonal to the connecting portion 4c, is provided on the opposite side of the fixing portion 4d, and is attached to the substrate.
