Abstract

A flat cable insertion socket has a pivotally connected cover for closing an open side of the socket and a plurality of internal terminal cavities for each receiving a terminal therein. The terminal each includes a barb portion that is provided at one side with at least two barbs. An additional hook may be optionally provided on the terminal opposite to the barb portion, so that a flat cable may be inserted into the socket to locate and be pressed between the barb portion and the additional hook without the risk of separating from the socket. The barb portions of the terminals in the flat cable insertion socket are so designed that the cover may be always located at an upward turnable position relative to the socket when the socket has been welded to a circuit board, and that the flat cable may always has its bared side effectively and electrically contacted with the terminals.

A flat cable inserting socket, comprising:

a main body defining a plurality of terminal cavities therein, a plurality of terminals separately located in said a plurality of terminal cavities, and a cover pivotally connected at two pivotal pins provided at two lateral ends to an open side of said main body;
each of said terminals including a barb portion completely received in on corresponding terminal cavity and a pin projected from on side of said main body opposite to said open side with said cover;
a flat cable being inserted into said main body via said open side, such that when said cover is pivotally turned to close onto said main body, said flat cable is pressed by said cover to contact with said barb portions of said terminals;
said flat cable insertion socket being characterized in that each of said terminals is provided on said barb portion at predetermined positions with at least two barbs, and at a position opposite to said barb portion with a hook-like projection, such that said flat cable may be inserted into said main body and held in a space between said barbs and said hook-like projections;
wherein said cover is provided near each of its two lateral inner ends with a locking rib, and said main body of said insertion socket is provided near each of its two lateral ends with a matching locking channel, such that when said cover is closed onto said main body, said locking rib is received in said locking channel;
said locking rib contains a catching rib formed on an outside surface of an outer sidewall of said locking channel, said cover contains an end rib to be positioned just outside of said outer sidewall of said locking channel when said locking rib is received in said locking channel, and said end rib contains a retaining rib formed on an inner sidewall of said end rib;
and
said catching rib and said retaining rib are structured such that said locking rib reversibly passes said catching rib to form a locked position when said locking rib is received in said locking channel.
