Abstract

The present invention provides a connector for flexible flat cable. The flexible flat cable forms a gap. The connector includes a male head, a female base and an electrical terminal. The male head includes a first housing and a second housing. A surface of the first housing forms a locking member to lock the notch and a side of the first housing forms a fastening member having a projection. The female base forms a second receiving space and a fastening arm. One end of the electrical terminal is disposed in the second accommodating space, and the other end protrudes from the second accommodating space. When the male joint is combined with the female base, the male protrusion abuts against the fastening arm, so that the fastening arm is moved from a first position to a second position until the protrusion is inserted into the opening of the fastening arm.

Connector

This creation is the technical field of a connector, especially a connector applied to a flexible flat cable.

Traditionally, flexible flat cables are used to provide signal transmission, which has the advantages of arbitrary deflection and high-frequency signal transmission capabilities. Its suitable fields of application are automotive products, home appliances, display screens, and smart phones.

The flexible flat cable is connected to the master work set on the circuit board through the male head (or male end). During the assembly operation, in order to allow the assembler to easily assemble without damaging the circuit board or the flexible flat cable, Many types of connection methods have been developed, and the connection method is accompanied by an automatic locking structure. Even in other applications, it is necessary to provide an unlocking structure at the same time.

This creation proposes a connector that allows assemblers to quickly assemble or disassemble.

The first objective of this creation is to provide a connector that is applied to a flexible flat cable that allows the flexible flat cable to be freely installed on or removed from the circuit board.

The second purpose of this creation is based on the above-mentioned connector, and the flexible flat cable can be snapped on the male connector by the male fastener.

The third objective of this creation is to combine the snap-fit arm of the female seat with a snap-fitting member with a bump according to the above-mentioned connector, so as to achieve the purpose of locking the male head to the female seat.

The fourth object of this creation is based on the above-mentioned connector, which pushes the snap arm by the convex block with the inclined surface to move, so that the snap piece can be easily combined with the snap arm to achieve the purpose of locking.

The fifth object of this creation is to move the snap arm according to the above-mentioned connector to disengage the projection from the opening of the snap arm to achieve the purpose of unlocking.

In order to achieve the above purpose and other purposes, the present invention provides a connector applied to a flexible flat cable. The two sides of the front edge of the flexible flat cable respectively form a notch. The connector includes a male head, a female seat and an electric terminal. The male head includes a first housing and a second housing. The first casing is combined with the second casing to form a first accommodating space for accommodating the flexible flat cable. A locking member is formed on a surface of the first casing to lock the notch and a side of the first casing to form a fastener. Among them, a convex piece protrudes from an inner edge of one of the fasteners. The female seat forms a second accommodating space and a snap-fit arm. Two sides of the second accommodating space are respectively provided with snap arms. The snap-in arm forms an opening. One end of the electrical terminal is disposed in the second accommodating space, and the other end protrudes from the second accommodating space. In the process of combining the male head with the female seat, the protrusion of the male head abuts the snap arm, so that the snap arm The position moves to a second position until the projection is inserted into the opening, the snap-in arm returns from the second position to the first position, or the snap-in arm moves from the first position to the second position to allow the male head to disengage from the female seat.
