Connector

Abstract

A connector includes contacts each having a contact portion, an elastic portion and a fulcrum portion between the contact portion and a connection portion, and a pressure receiving portion; a housing fixing the contacts; and a slider having urging portions pivotally moved between the connection and pressure receiving portions of the contacts to urging the contact portions against the circuit board, thereby achieving reliable connection and miniaturization of the connector. In an aspect, the housing is formed on the side of a board insertion opening with a recessed portion for conducting the board. In another aspect, the contact includes upper and lower contact portions one above the other arranged alternately staggered so as to be connected to a circuit board having contact portions alternately staggered, so that no defective connection occurs, even if the circuit board is inserted erroneously upside down. In a further aspect, the connector further includes locking members having an engaging portion which engages an anchoring portion of the circuit board to prevent the circuit board from being removed. In one aspect, contacts of two kinds are inserted into the housing from opposite sides, respectively so that these contacts of the two kinds are into contact with the contact portions on respective surfaces of the circuit board. In a further aspect, moreover, a plate-shaped piece is provided in opposition to the contact portions of the contacts to prevent the housing from being deformed.

Description

technical field [0001] The present invention relates to a connector used on a mobile or cellular phone, a personal notebook computer, a digital video camera or the like, and more particularly to a connector capable of reliably pushing contacts against a flexible printed circuit board or flexible ribbon cable, it is convenient to guide the circuit board or ribbon cable into the connector and at the same time realize the miniaturization of the connector, even if the circuit board is inserted upside down by mistake, it can eliminate any connection defects and reliably connect the circuit The locking of the board or cable to the connector enables miniaturization of the connector even with contact portions on both surfaces of the board and strengthens the connector ready to be mounted on the board and the cable. Background technique [0002] In general, connectors used in mobile phones, charge-coupled device (CCD) cameras, or the like are very thin (so-called lighter, more compac...

AI Technical Summary

Problems solved by technology

However, in order to ensure the strength of each component and specification requirements or user requirements, it is not possible to further reduce the height of the connector

[0020] With the connector 60 shown in Figures 30A and 30B, the insertion of the circuit board 40 or ribbon cable and the pushing of the contact portion 22 of the contact 64 against the circuit board or ribbon cable occurs only on the receptacle side of the housing. , so this operation becomes more difficult as the connector miniaturization

Additionally, where contacts are required to be spaced extremely narrowly, the insertion of the contacts into the housing from only one direction can hinder or impede the miniaturization requirements of the connector

[0021] The second point, for the structure described above, in the case where the contacts are arranged in the housing in such a way that their connecting parts are placed on the socket side of the housing, it is inevitable that the connecting parts of the contacts will be separated from the housing. In order to guide the circuit board or ribbon cable, this will limit the miniaturization of the connector because the connecting part protrudes from the housing

For the extremely thin shell in this connector, when the circuit board is inserted into the connector, the shell may not be able to bear the contact force, so that the shell is deformed and the connection is unstable, resulting in connection failure or failure, or even cause damage to the housing

Making the case thicker avoids this problem, but does not allow for a reduction in height

The connectors disclosed in Patent Documents 1 and 2 have contacts arranged in narrow pitches and are thinner in shape (so-called lighter, more compact connectors), so the problems described above are more severe in such connectors. serious
