Description

  The present invention relates to an electrical connector. In particular, an electrical connector for electrically connecting a flat flexible cable such as FPC (Flexible Printed Circuit) or FFC (Flexible Flat Cable) or a plate-like connecting member such as a rigid printed board to a rigid printed board. The present invention relates to a structure of an electrical connector provided with a lock mechanism that prevents unfitting with a connecting member.

  The FPC can mount an electronic component and can be used as a flexible printed board. In addition, since the FPC has flexibility and can be thinned, in recent years, as a flexible cable in which a plurality of conductor patterns are arranged on a plane instead of a flat cable in which a plurality of wires are insulated and assembled, Used inside equipment.

  As an electrical connector for electrically connecting a plate-like connecting member such as an FPC and a hard printed circuit board (so-called rigid board), the housing mounted on the printed circuit board is closed by opening and closing the open / close lever connected to the housing. An open / close-type electrical connector is known in which a contact disposed on the FPC is brought into contact with a conductor pattern of an FPC.

  The open / close type electrical connector as described above is called a ZIF (Zero insertion Force) connector, and has an advantage that the connection member can be connected to the electrical connector without requiring a strong force to insert and remove a plate-like connection member such as an FPC. is there.

  On the other hand, the ZIF connector requires the opening / closing lever to be opened and closed each time the connecting member is connected to the electrical connector. Therefore, by inserting the connecting member into the opening opened on the front surface of the housing, the connecting member is connected to the electrical connector. A so-called non-ZIF connector that can be connected has been developed. Since the non-ZIF connector does not require an openable opening / closing lever, there is an advantage that the configuration is simplified.

  For example, a Non-ZIF type FPC connector includes a lock mechanism having a lock lever that can be engaged with recesses cut out on both side edges of the FPC. By inserting the FPC into the opening opened on the front surface of the housing, the lock lever can be locked in the concave portion of the FPC, and the FPC can be prevented from coming off from the FPC connector. On the other hand, by operating the lock lever from the outside, the engagement between the lock lever and the FPC can be released, and the FPC can be pulled out from the FPC connector.

  However, the FPC connector provided with such a lock mechanism has a fear of damaging the FPC if the user forgets to operate the lock lever and pulls out the FPC from the FPC connector. For this reason, a Non-ZIF type electrical connector that can suppress damage to the FPC when the FPC is removed is disclosed (for example, see Patent Document 1).

  18 and 19 of the present application correspond to FIGS. 1 and 2 of Patent Document 1. 20 and 21 of the present application correspond to FIGS. 4 and 9 of Patent Document 1. Further, FIG. 22 of the present application corresponds to FIG.

  Moreover, FIG. 23 and FIG. 24 of this application correspond to FIG. 10 and FIG. 25 and 26 of the present application correspond to FIGS. 12 and 14 of Patent Document 1.

  Referring to FIGS. 18 to 26, a conventional electrical connector (hereinafter abbreviated as a connector) 9 includes a rectangular parallelepiped housing 91 and a plurality of bellows-shaped contacts 92. The connector 9 includes a pair of reinforcing tabs 93a and 93b and a lock lever 94.

  Referring to FIG. 23 or FIG. 24, the connector 9 can be mounted on one surface of the printed circuit board 9p. Referring to FIG. 18 or FIG. 23 and FIG. 24, the housing 91 has an insertion opening 91a opened on the front surface thereof. The housing 91 has an FPC housing chamber 91r that communicates with the insertion opening 91a. Referring to FIG. 18 or FIG. 22, the FPC 8f can be inserted into the FPC accommodating chamber 91r through the insertion opening 91a.

  Referring to FIG. 23, the plurality of contacts 92 are arranged in parallel in the FPC housing chamber 91r. When the FPC 8f is inserted into the FPC housing chamber 91r, the contact of the contact 92 and the conductor pattern 81c exposed on the other surface of the FPC 8f can be contacted. The base end portion of the contact 92 is soldered to one surface of the printed board 9p. Thereby, the connector 9 can electrically connect the FPC 8f and the printed board 9p.

  Referring to FIG. 22, the FPC 8f has a pair of rectangular recesses 8d and 8d cut out at both side edges of the terminal. Further, the FPC 8f has a protruding piece 8e that is continuous with the recess 8d formed at the terminal. 22 to 24, the FPC 8f has a reinforcing plate 81f bonded to one surface of the terminal. Further, the FPC 8f exposes a plurality of conductor patterns 81c on the other surface of the terminal.

  Referring to FIG. 23 or FIG. 24, the FPC 8f has a pair of insulating layers 81i and 81i covering both surfaces of a plurality of conductor patterns 81c. One insulating layer 81i is continuous with the reinforcing plate 81f. A ground pattern 81g is formed on the other insulating layer 81i.

  Referring to FIG. 18 to FIG. 20 and FIG. 23 or FIG. 24, the pair of reinforcing tabs 93 a and 93 b are incorporated at both ends of the housing 91. A part of the pair of reinforcing tabs 93 a and 93 b is exposed from the bottom surface of the housing 91. By soldering a part of the pair of reinforcing tabs 93a and 93b to one surface of the printed circuit board 9p, the bonding strength of the connector 9 to the printed circuit board 9p can be reinforced.

  Referring to FIG. 23 or FIG. 24, the pair of reinforcing tabs 93a and 93b have ground terminals 931 inverted toward the FPC housing chamber 91r. Referring to FIG. 23, when FPC 8f is inserted into FPC accommodating chamber 91r, ground pattern 81g exposed on the other surface of FPC 8f can be brought into contact with ground terminal 931.

  Referring to FIG. 21 or FIG. 24, the lock lever 94 is formed in a gate shape by molding a band-shaped metal plate. The lock lever 94 has an operation lever 94r made of a flat top plate at the center. The lock lever 94 has a pair of elastic arms 94a and 94a arranged to face each other.

  Referring to FIG. 21 or FIG. 24, the elastic arm 94a has a locking claw 94n projecting in a right triangle shape from its plate thickness surface in the middle portion. The elastic arm 94a has a press-fitting piece 94b that is inverted from the distal end portion toward the proximal end portion of the elastic arm 94a.

  With reference to FIG. 21 or FIG. 24, the pair of press-fitting pieces 94 b and 94 b can be press-fitted into the housing 91 from the back surface of the housing 91 toward the front surface. The pair of press-fitting pieces 94b and 94b are fixed to the housing 91, so that the pair of elastic arms 94a and 94a can be held in the housing 91 so as to be able to bend.

  Referring to FIG. 23, when the FPC 8f is inserted into the FPC accommodating chamber 91r, the tip edge of the FPC 8f slides along the slope of the locking claw 94n, so that the elastic arm 94a can be pushed down. Referring to FIG. 22, when protruding piece 8e of FPC 8f gets over locking claw 94n, elastic arm 94a returns to engage locking claw 94n with recess 8d (see FIG. 24 or FIG. 25). As a result, the FPC 8 f can be prevented from coming off from the connector 9.

  Referring to FIG. 24, by pressing the operating lever 94r, the elastic arm 94a can be pushed down, and the engagement between the locking claw 94n and the recess 8d can be released. Then, the FPC 8f can be pulled out from the connector 9.

  Referring to FIG. 25, if the user forgets to depress the operating lever 94r or does not sufficiently depress the operating lever 94r (see FIG. 24), if the FPC 8f is pulled out from the connector 9, the projecting piece 8e will be excessive. Bending stress acts.

  Referring to FIG. 26, the FPC accommodating chamber 91r of the housing 91 has an escape portion 91e into which the protruding piece 8e that contacts the locking claw 94n and is deformed in the inserting direction of the FPC 8f enters by pulling the FPC 8f in the removal direction. Since it is provided on the rear wall 91w side of 91, damage to the FPC 8f can be suppressed when the FPC 8f is removed.

  18 to 26, the connector 9 according to the prior art is based on the premise that the bending strength of the protruding piece 8e formed at the end of the FPC 8f is not relatively strong. In this case, when the FPC 8f is inserted into the FPC accommodating chamber 91r (see FIG. 24), it is conceivable that the projecting piece 8e is deformed and gets over the engaging claw 94n without the projecting piece 8e pushing down the engaging claw 94n. Thereby, when the latching claw 94n is fitted in the recess 8d (see FIG. 24 or FIG. 25), there is a concern that a click feeling by hearing or touch cannot be sufficiently obtained.

  Further, since the connector 9 according to the prior art deforms the protruding piece 8e and pulls out the FPC 8f from the connector 9, there is a concern that undesirable residual stress is generated in the protruding piece 8e.

  When a connecting member such as an FPC is inserted into the electrical connector, a click feeling that the plate-like connecting member is locked can be obtained, and the connecting member can be easily pulled out from the electrical connector without deforming the connecting member. There is a need for an electrical connector with a locking mechanism. The above can be said to be the subject of the present invention.
