Description

The present invention relates to an electrical connector. In particular, it is an electric connector that electrically connects a flat flexible cable such as FPC (Flexible Printed Circuit) or FFC (Flexible Flat Cable), or a plate-shaped connecting member such as a hard printed circuit board to a hard printed circuit board. The present invention relates to the structure of an electric connector having a locking mechanism for preventing non-fitting with a connecting member.

The FPC can be used as a flexible printed circuit board on which electronic components can be mounted. Further, since FPC has flexibility and can be made thinner, in recent years, instead of a flat cable in which a plurality of electric wires are insulated and coated and assembled, an electron is used as a flexible cable in which a plurality of conductor patterns are arranged on a flat surface. It is used inside the equipment.

As an electric connector that electrically connects a plate-shaped connecting member such as an FPC and a rigid printed circuit board (so-called rigid board), the housing is formed by closing the opening / closing lever that is openably connected to the housing mounted on the printed circuit board. There is known an open / close type electric connector that brings a contact arranged in a contact with a conductor pattern of an FPC.

The open / close type electric connector as described above is called a ZIF (Zero insertion Force) connector, and has an advantage that the connecting member can be connected to the electric connector without requiring a strong force for inserting and removing a plate-shaped connecting member such as an FPC. is there.

On the other hand, in the ZIF connector, it is necessary to open and close the opening / closing lever each time the connecting member is connected to the electric connector. Therefore, by inserting the connecting member into the opening opened on the front surface of the housing, the connecting member can be turned into the electric connector. So-called Non-ZIF connectors that can be connected have been developed. Since the Non-ZIF connector does not require an opening / closing lever that can be opened / closed, there is an advantage that the configuration is simple.

For example, a Non-ZIF type FPC connector includes a locking mechanism having a lock lever that can engage 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 recess 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 concern that the FPC may be damaged if the FPC is pulled out from the FPC connector by forgetting to operate the lock lever. For this reason, a Non-ZIF type electric connector capable of suppressing damage to the FPC when the FPC is removed is disclosed (see, for example, Patent Document 1).

Further, FIGS. 23 and 24 of the present application correspond to FIGS. 10 and 11 (a) of Patent Document 1. 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. Further, the connector 9 includes a pair of reinforcing tabs 93a and 93b and a lock lever 94.

With reference to FIG. 23 or FIG. 24, the connector 9 can be mounted on one side of the printed circuit board 9p. With reference to FIG. 18 or FIGS. 23 and 24, the housing 91 has an insertion opening 91a that opens in front of it. Further, the housing 91 has an FPC accommodating chamber 91r communicating with the insertion opening 91a. With reference 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 side by side in the FPC accommodating chamber 91r. When the FPC 8f is inserted into the FPC accommodating chamber 91r, the contact point of the contact 92 can be brought into contact with the conductor pattern 81c exposed on the other surface of the FPC 8f. The base end portion of the contact 92 is soldered to one surface of the printed circuit board 9p. As a result, the connector 9 can electrically connect the FPC 8f and the printed circuit board 9p.

Referring to FIG. 22, the FPC 8f has a pair of square recesses 8d and 8d cut out on both side edges of the terminal. Further, the FPC 8f forms a projecting piece 8e continuous with the recess 8d in the terminal. Referring to FIGS. 22 to 24, the FPC 8f has a reinforcing plate 81f adhered to one surface of the terminal. Further, the FPC8f 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 set of insulating layers 81i and 81i covering both sides of the 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.

With reference to FIGS. 18-20 and 23 or 24, the pair of reinforcing tabs 93a and 93b are incorporated at both ends of the housing 91. A part of the pair of reinforcing tabs 93a and 93b 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 towards the FPC containment chamber 91r. When the FPC8f is inserted into the FPC storage chamber 91r with reference to FIG. 23, the ground pattern 81g exposed on the other surface of the FPC8f can be brought into contact with the ground terminal 931.

With reference to FIG. 21 or FIG. 24, the lock lever 94 is formed into a gate shape by molding a strip-shaped metal plate. The lock lever 94 has an operating lever 94r made of a flat top plate in the central portion. Further, the lock lever 94 has a pair of elastic arms 94a and 94a arranged so as to face each other.

With reference to FIG. 21 or FIG. 24, the elastic arm 94a has a locking claw 94n protruding from the plate thickness surface in a right-angled triangular shape in the intermediate portion. Further, the elastic arm 94a has a press-fit piece 94b that is inverted from the tip end portion toward the base end portion of the elastic arm 94a.

With reference to FIG. 21 or FIG. 24, the pair of press-fit pieces 94b / 94b can be press-fitted into the housing 91 from the back surface to the front surface of the housing 91. Then, by fixing the pair of press-fit pieces 94b / 94b to the housing 91, the pair of elastic arms 94a / 94a can be flexibly held in the housing 91.

When the FPC 8f is inserted into the FPC accommodating chamber 91r with reference to FIG. 23, the elastic arm 94a can be pushed down by the tip edge of the FPC 8f sliding along the slope of the locking claw 94n. With reference to FIG. 22, when the projecting piece 8e of the FPC 8f gets over the locking claw 94n, the elastic arm 94a returns and the locking claw 94n can be engaged with the recess 8d (see FIGS. 24 or 25). As a result, the FPC 8f can be prevented from coming off from the connector 9.

By pressing the operation lever 94r with reference to FIG. 24, 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 FPC 8f is pulled out from the connector 9 without pressing the operation lever 94r sufficiently or without sufficiently pressing the operation lever 94r (see FIG. 24), the protrusion 8e is excessive. Bending stress acts.

Referring to FIG. 26, in the FPC accommodating chamber 91r of the housing 91, a relief portion 91e in which the projecting piece 8e deformed in the insertion direction of the FPC 8f abuts on the locking claw 94n is inserted by pulling the FPC 8f in the removal direction. Since it is provided on the back wall 91w side of 91, it is said that damage to the FPC 8f can be suppressed when the FPC 8f is removed.

Referring to FIGS. 18 to 26, the connector 9 according to the prior art is premised on the fact that the bending strength of the projecting piece 8e formed on the terminal 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 deforms and overcomes the locking claw 94n without pushing down the locking claw 94n. As a result, when the locking claw 94n is fitted into the recess 8d (see FIG. 24 or 25), there is a concern that a sufficient auditory or tactile click feeling cannot be obtained.

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

When a connecting member such as an FPC is inserted into the electric connector, a click feeling that the plate-shaped connecting member is locked can be obtained, and the connecting member can be easily pulled out from the electric connector without deforming the connecting member.
