Description

Connector for flat conductor

The present invention relates to a connector for a flat conductor, and more particularly to a connector for FPC (flexible circuit board) or FFC (soft flat cable).

Flat conductors such as flexible circuit boards (FPC) or flexible flat cable (FFC) are well known conductors. The connector of the FPC/FFC generally includes a pressing cover, a plastic body and a terminal disposed on the plastic body. The plastic body is inserted into the FPC/FFC, so that the FPC/FFC is in contact with the terminal, and the pressing cover can be opened. Actuated between closed positions or closed, the FPC/FFC can be pressed when closed.

However, as the high-frequency signal transmitted is getting faster and faster, compared with such a pitch-density connector, since the number of conductive terminals is large and the spacing between the two is small, the connector is extremely susceptible to signal interference, such as silent interference and electromagnetic waves. Interference, impedance matching, noise interference, crosstalk interference of adjacent terminals, and thus the bandwidth and signal quality are not up to standard and affect the operation of the electronic device.

For example, the Republic of China new certificate number: TWM429227 (application number: 100223509) discloses that an electrical connector includes a seat body, a conductive terminal that is disposed through the base body, and a pressing member and a rotating cover pivotally connected to the pressing member. Where the pressing element and The conductive terminals are disposed on the base body and have an array of bent positioning grooves and slots. Through the above design, there is a lack of skin effect that can reduce the noise interference and electrostatic interference caused by the shape of the terminal.

In general, this design has fully met the needs of traditional FPC/FFC connectors. However, in recent years, due to the high-speed transmission requirements of personal computers or other electronic products, due to the design, the terminals, the pressing components and the slots, and the positioning slots The gap is small and close, resulting in a relatively uniform medium between the two terminals and the pressing elements, so that there is a large capacitance effect and the signal is susceptible to interference, which will eventually have doubts on the high-speed transmission characteristics of the connector. In addition, the plastic (insulating) body of the general connector is mainly made of plastic material, so that the overall structure is more easily deformed and broken, especially the slot on the plastic body is excessively opened, and the overall height of the connector is lower, such as low. When the thickness is less than 1.5 mm, the strength of the plastic body is less likely to be deformed and broken.

In order to overcome the above drawbacks, the present invention provides a connector for a flat type conductor, which is characterized in that the connector has an effect of lifting to prevent telecommunication interference, thereby providing a use for high frequency transmission. At the same time, it is also possible to enhance the strength of the insulating body to prevent breakage and the like.

The technical solution adopted by the present invention to solve the technical problem is: a connector for a flat conductor, comprising an insulative housing, a plurality of conductive terminals arranged in the insulating body, and a movable device between the open and closed positions. a gland, a metal embedding member and two grounding fixing members disposed on both sides of the insulating body, the insulating body has an insertion space and a plurality of terminal slots, and each of the conductive terminals is disposed at a corresponding position a terminal slot, each of the conductive terminals has a contact portion extending into the insertion space, wherein the metal embedded member and the conductive terminal are disposed vertically opposite to each other and embedded in the top of the insulating body, and the metal embedded member is fixed to the ground The connection forming the contact between the members forms an electrical connection, and the metal embedded member has a buried substrate portion embedded in the insulating body and a plurality of elastic pressing portions extending from the embedded substrate portion, and pressing The cover is formed with a plurality of axial grooves, and a side wall forming the axial groove protrudes from the rotating shaft, and a distal end portion of the elastic pressing piece portion is elastically pressed against the rotating shaft.

Further, the grounding fixing member has a base portion, an insertion portion extending from the base portion and being inserted into the insulating body, and a connecting piece portion extending from the bottom end of the base portion, the metal embedded member having a contact piece extending outside the insulating body The contact piece contacts the connecting piece.

The beneficial effect of the creation is that a buried metal piece is directly embedded in the top of the insulating body, and the buried metal piece is directly buried in the insulating body, and is in contact with the grounding fixing member to achieve electrical connection to form a grounding purpose. . This allows the connector to enhance the prevention of telecommunications interference, such as silent interference, electromagnetic interference, impedance matching, noise interference, crosstalk interference from adjacent terminals, and thus can be used for high frequency transmission. At the same time, the elastic pressing piece portion of the embedded metal member is pressed against the rotating shaft to stably fix the rolling cover to the insulating body. On the other hand, the metal member is embedded in the insulating body, so that when the overall height of the connector is lower (for example, less than 1.5 mm or less), the strength of the insulating body 1 can be enhanced to prevent breakage and the like.
