Description

  The present invention relates to an FPC connector. In particular, the present invention relates to a connector that connects to a flat flexible cable such as an FPC (Flexible Printed Circuit) or FFC (Flexible Flat Cable). In this specification, the flat flexible cables are collectively referred to as FPC. The FPC connector according to the present invention is also a so-called ZIF (Zero Insertion Force) type FPC connector that requires little force when inserting and removing the FPC.

  Between recent electronic devices such as electronic component modules and printed boards mounted on portable information devices such as DVC (Digital Video Camera) and DSC (Digital Still Camera), mobile phones and PDAs (Personal Digital Assistance) For connection, FPC, which is a flat flexible cable, is used.

  In general, an FPC connector that is surface-mounted on a printed circuit board, that is, a so-called surface-mount type FPC connector, includes a housing in which a recess into which an FPC is inserted is formed, and a plurality of side-by-side mounted on the housing at a predetermined pitch. It has a contact. And in order to make FPC and these contacts contact, the connector for FPC is provided with the actuator which opens and closes a recessed part.

  FPC connectors that are surface-mounted on a printed circuit board are required to have a low mounting height (to reduce the height) in order to increase the mounting density, and there are many contacts arranged on this surface-mounted FPC connector. Pinning and narrowing are in progress.

  Further, in the FPC connector that enables such a reduction in height, the lead portion at one end of the contact mounted on the housing extends from the end portion of the housing and is soldered to the printed circuit board. However, since the strength of the housing is insufficient, there is a problem that the flatness of the aligned lead portions is not good and soldering with high reliability cannot be performed.

  This FPC connector is designed to reduce the height against such problems, and it can be connected with high reliability while zeroing the insertion force of the FPC and ensures flatness in the lead part of the contact. A connector that can be used has been invented (see, for example, Patent Document 1).

The connector according to Patent Document 1 includes a housing that supports a plurality of contacts arranged in parallel at a predetermined pitch, and a metal cover that has a substantially U-shaped cross section. The metal cover is slidably attached to the housing in the longitudinal direction of the contact. At the fully mounted position of the metal cover, the tip of the pressing plate formed on the upper plate of the metal cover and the contact formed on the contact are vertically opposed. In the external retreat position of the metal cover, a sufficient gap is formed between the front end portion of the pressing plate and the contact portion so that the FPC can be inserted.
Japanese Patent Laid-Open No. 11-54173

  The connector according to Patent Document 1 opens and closes the front end of the metal cover by sliding a metal cover formed in a substantially U-shaped cross section. The FPC can be mounted by sliding the metal cover away from the housing. On the other hand, the FPC can be brought into contact with the contact by sliding the metal cover closer to the housing.

  However, the connector according to Patent Document 1 is an FPC connector with a low profile, and there is a problem that it is difficult to slide the metal cover when mounted on a printed board. This is because it is considered that there is no room for gripping the metal cover with a low-profile connector. Therefore, an actuator that is easy to operate is required to insert and remove the FPC from the low-profile connector.

  Moreover, since the connector according to Patent Document 1 slides in a direction away from the metal cover with respect to the housing, there is a problem that an electronic component cannot be mounted in this region of the printed board. Recent printed circuit boards are required to mount electronic components overly densely, and such a dead space (non-mounting region) is not preferable. Therefore, a printed circuit board connector that is surface-mounted on a printed circuit board is required to have a connector capable of overpackaging electronic components. The above can be said to be the subject of the present invention.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a low-profile FPC connector having an actuator that can be easily operated, and an FPC connector capable of densely mounting electronic components on a printed circuit board. And

  In order to satisfy the above-mentioned object, the present inventors can solve the above-mentioned problems by connecting a back-flip type lever that opens and closes the front ends of U-shaped plate clips that sandwich the FPC to the housing. Based on this, the following new FPC connector was invented.

  (1) A flat plate-like housing having a recess into which the FPC is inserted, a plurality of contacts arranged in the recess of the housing and connected to the FPC, and one strip piece attaching the FPC to the plurality of contacts. The other band plate piece is locked to the bottom surface of the housing, and a U-shaped plate clip in which the base ends of these band plate pieces are coupled to each other, a pair of facing arms, and these arms A lever having a band-like handle for connecting the base ends of the pair of arms, wherein the pair of arms includes a back-flip type lever that pivotably connects to both wings of the housing, and the pair of arms The arm is an FPC connector having a pair of insulator pieces at the tip end portions that engage with both wings of the one strip piece piece to open and close the tip end portion of the one strip piece.

  The FPC connector according to the invention of (1) includes a flat plate-shaped housing, a plurality of contacts, a plate clip having a U-shaped cross section, and a back flip lever. The housing has a recess into which the FPC is inserted. The plurality of contacts are arranged in the recess of the housing and are connected to the FPC.

  In the plate clip, one strip piece urges the FPC to a plurality of contacts. In the plate clip, the other strip piece is locked to the bottom surface of the housing. And the board clip has couple | bonded the base end parts of these strip pieces.

  The lever has a pair of arms facing each other and a band-shaped handle that connects the base ends of these arms. In this lever, the tip ends of a pair of arms are rotatably connected to both wings of the housing.

  And a pair of arm has a pair of insulator piece in the front-end | tip part. These lever pieces engage with both wings of one band plate piece to open and close the front end portion of the one band plate piece.

  In general, in FPC, a copper foil serving as a conductor pattern is bonded to a base film formed of insulating polyester or polyimide. The conductor pattern is covered with an insulating film, but the conductor pattern is exposed at the end portion of the FPC so as to be in conductive contact with, for example, a contact provided in the connector. The FPC applied to the connector according to the present invention is preferably a single-sided FPC having a conductive pattern on one side of the base film, and the conductive pattern is exposed on one side of the base film at the end of the single-sided FPC.

  The housing may have an insulating property, and the insulating housing may be a housing made of a non-conductive material. For example, a synthetic resin is molded to form an insulating housing having a desired shape. Obtainable. As will be described later, the first housing and the second housing may be molded separately, or the first housing and the second housing may be combined to obtain a housing having a desired shape.

  The housing may have a rectangular opening at one end for insertion of the FPC, and the FPC is inserted into an open recess having a thin rectangular parallelepiped shape. The FPC may be inserted from the opening side of the recess toward the stop wall, and a pair of opposed inner walls forming the recess guide the width direction of the FPC and align (connect) with a plurality of contacts. . The FPC inserted into the recess of the housing may stop by contacting the stop wall, and the insertion depth of the FPC is defined. A comb-like interelectrode wall may be formed on the bottom surface of the recess so that adjacent contacts do not contact each other.

  The contact may have conduction, and the contact having conduction may be a contact made of a conductive material. For example, a copper alloy plate is precision stamped to obtain a contact having a desired shape. be able to.

  The contact may be a cantilever contact (cantilever contact) whose fixed end is fixed to the housing and whose free end is elastically deformed, and a contact is provided at the free end. By energizing the FPC to this contact, the contact can apply a predetermined contact force to the conductor pattern of the FPC as a reaction.

  The contact may be composed of a first contact and a second contact having different distances from the fixed end to the contact, for example, a first contact having a long free end and a second contact having a short free end. If the first contacts and the second contacts are alternately arranged, the contacts can be arranged at a narrow pitch. This is because a long free end having a large displacement in a direction orthogonal to the bending direction is provided with a gap corresponding to one pitch with respect to the short free end.

  The contact point of the contact may protrude from the bottom surface of the concave portion of the housing, and as will be described later, in the state where the front end portion of one strip plate piece of the plate clip is opened, the contact point and the bottom surface of the one strip plate piece are: The connector may have a distance equal to or greater than the thickness of the FPC, and this connector constitutes a ZIF connector that requires little force when the FPC is inserted into and removed from the opening.

  The plate clip is preferably made of a metal plate having spring properties, and the developed metal plate can be bent and formed to obtain a plate clip having a U-shaped cross section. The plate clip may be disposed so as to straddle the housing and sandwich the housing. It can also be said that the housing regulates the displacement of the one strip piece so that the force that the one strip piece urges is retained.

  The back flip lever is a lever that tilts (turns) to the rear of the connector, with the FPC insertion direction defined as the front of the connector. Since this back flip lever is tilted so as to be close to the three surfaces behind the connector (housing), there is an advantage that it does not occupy the mounting area behind the connector. In addition, this back flip type lever also has an advantage that it is easy to operate because the connection is completed by tilting the lever back after inserting the FPC into the connector.

  In the present invention, tilting the lever backward is defined as “closing the lever”, and turning the lever forward is defined as “opening the lever”. In an embodiment, the lever can be opened and closed approximately 90 degrees.

  The lever is preferably made of a rigid metal body. For example, the developed belt can be bent and formed so that the pair of arms and the handle can be integrated. A pair of insulator pieces and a pair of rotating shafts to be described later may be press-molded in advance on both ends of the developed band plate, or may be coupled to the pair of arms by welding.

  The center of rotation of the tip of the arm and the center of rotation of the insulator piece may coincide with each other, and the length (distance) from the center of rotation of the arm to the extended end is from the center of rotation of the insulator piece to the point of action. It may be sufficiently larger than the length (distance) of the arm, and the arm and the insulator piece are linked to a booster that applies the “principle principle”. It can also be said that the arm and the insulator piece constitute a bell crank. An eccentric cam may be used instead of the insulator piece.

  Therefore, when the handle is held and the lever is opened and closed, the front end portion of the one strip piece can be opened and closed with a slight force. In the embodiment, when the lever is opened, the tip of one of the strip pieces can be opened, and the FPC can be inserted into the connector. On the other hand, when the lever is closed, the tip of one of the strip pieces can be closed, and the FPC can be connected to the connector.

  Thus, in the FPC connector according to the invention of (1), the back flip type lever that opens and closes the front ends of the U-shaped plate clip sandwiching the FPC is rotatably connected to the housing. Is easy. Further, while the metal cover of Patent Document 1 slides backward, the plate clip corresponding to the metal cover does not move, so that electronic components can be mounted on the printed circuit board in an overcrowded manner.

  (2) The FPC connector according to (1), wherein the housing includes a first housing that holds the plurality of contacts and a second housing that is sandwiched between the pair of strip pieces.

  For example, the first housing may be molded with a plurality of contacts integrally, the second housing may be pre-assembled with a plate clip, and the first housing and the second housing are assembled so as to be difficult to separate.

  The FPC connector according to the invention of (2) has an effect of reducing the total assembly cost by dividing the housing into the first housing and the second housing.

  In the FPC connector according to the invention of (3), the plurality of lead portions soldered to the printed circuit board are arranged in the cutout portions formed at the end portions of the first housing. It is easy to observe the state. For example, the solder joint state of the lead portion can be observed using an image processing apparatus.

  (4) The FPC connector according to any one of (1) to (3), wherein the plate clip is made of a metal plate that shields electromagnetic waves and covers the plurality of contacts.

  The FPC connector according to the invention of (4) has an effect that it can shield electromagnetic waves of high-speed signals transmitted from a plurality of contacts, and can shield external interference electromagnetic waves.

  (5) The one strip piece has a pair of locking pieces which are inverted in a U shape from the tip end portion toward the base end portion on both wings, and the terminal portions of these locking pieces are the pair The connector for FPC in any one of (1) to (4) latched on the bottom face of the insulator piece.

  In the FPC connector according to the invention of (5), since the terminal portions of the pair of locking pieces provided on both wings of the one band plate piece are locked to the bottom surfaces of the pair of lever pieces, In the state where the front end portion of the FPC is closed, it is possible to resist the force of pulling out the FPC from the connector. That is, it is possible to prevent the leading end portion of one of the strip pieces from opening carelessly.

  (6) The pair of arms has a pair of pivot shafts protruding in opposite directions at the tip, and the housing is formed on both wings of the housing to receive and support the pair of pivot shafts. A pair of notched bearing portions, and a pair of tabs having one end fixed to both wings of the housing and the other end pressing the pair of rotating shafts difficult to separate from the bearing portion.
