Abstract

Fixing a flat cable (7) to a cable connector member (3) of a two-piece electrical connector (1) is performed by a slider (10) inserted together with one end portion of the flat cable (7) into a connector housing (20). A metallic shall (13) fixedly supports the slider (10) therein and is slidably fitted on the connector housing (20) for providing the electro-magnetic shielding. Insertion and removal of the slider (10) for the connector housing (20) are performed by sliding operation of the metallic shell (13) on the connector housing (20).

Claims

1. A two-piece electrical connector comprising a cable connector member to be removably mounted on one end portion of a flat cable to establish mechanical and electrical connections with said flat cable and mating connector member which are to be electrically and mechanically connectored to an associated connection object and to be mated with said cable connector member for establishing an electrical connection between said flat cable and said associated connection object, said flat cable comprising a plurality of signal conductors embedded in an electrical insulator film and partially exposed at one end portion thereof in one surface of said insulator film, wherein said cable connector member comprises:

a first insulator having a rear opening for receiving said one end of said flat cable;

a plurality of first contact elements fixed in said first insulator, said first contact elements individually having first contact portions and first terminal portions disposed in said rear opening;

an insulator slider which is slidably fitted into said rear opening to press said one end portion of said flat cable onto said first terminal portions while it is being inserted together with said one end portion of said flat cable into said rear opening so that said first terminal portions come into a pressed contact with said signal conductors, respectively; and

a first metallic shell of a generally box shape having a front open end and fixedly supporting and partially enclosing said insulator slider therein, said metallic shell being fitted onto said first insulator and slidable on said first insulator upon an insertion of said insulator slider into said rear opening;

and wherein said mating connector member comprises;

a second insulator;

a plurality of second contact elements fixedly supported in said second insulator and individually having second contact portions exposed from said second insulator, said second contact portions coming into contact with said first contact portions when said mating connector member is mated with said cable connector member, said second contact elements individually having second terminal portions to be connected to said associated connection object; and

a second metallic shell mounted on and covering an outer surface of said second insulator, said second metallic shell being partially fitted onto said cable connector member to come into contact with said first metallic shell when said mating connector member is mated with said cable connector member.

2. The two-piece electrical connector as claimed in claim 1, said flat cable further having a ground pattern formed on a surface of said insulator film which is opposite to said one surface of said insulator film, wherein said first metallic shell is provided with an engaging portion for engaging with said ground pattern of said flat cable.

3. The two-piece electrical connector as claimed in claim 2, wherein said insulator slider comprises an insertion portion to be inserted within said rear opening and a support portion fixedly supported by said first metallic shell, said insulator slider having a flat surface continuous from said insertion portion to said support portion, said first metallic shell having an inner flange portion as said engaging portion extending inwardly therein and on said flat surface of said insulator slider, said first metallic shell having a rear aperture adjacent to said inner flange portion for receiving said one end portion of said flat cable with said ground pattern engaging with said inner flange portion, when said insulator slider is inserted into said rear opening together with said flat cable.

4. A cable connector with metallic shell means and cable fixture means, said metallic shell means being mounted on and covering an outer surface of a connector housing of said cable connector, said connector housing having a rear opening for receiving one end portion of a flat cable, said one end portion being fixedly mounted in said opening by said cable fixture means for establishing electrical and mechanical connection of said cable to said cable connector, said cable connector being matable with a mating connector with gn outer shell, wherein said fixture means is an insulator slider which is slidably fitted into said rear opening together with said one end portion od said flat cable, and wherein said metallic shell means is a box-shaped metallic shell member with a front open end, said metallic shell member fixedly supporting and partially enclosing said insulator slider therein and having a rear aperture for receiving said one end portion of said flat cable therethrough, said metallic shell member being fitted onto said connector housing and slidable on said connector housing so as to insert said insulator slider into said rear opening together with the flat cable.

5. A cable connector as claimed in claim 4, said flat cable having a ground pattern formed on an outer surface, wherein said insulator slider comprises a insertion portion to be inserted within said rear opening and a support portion fixedly supported by said metallic shell member, sid insulator slider having a flat surface continuous from said insertion portion to said support portion, said metallic shell member having an inner flange portion extending inwardly therein from a position close to said rear aperture and on said flat surface of said insulator slider, said inner flange portion coming into engagement with said ground pattern of said flat cable when said one end portion of said flat cable is received in said rear aperture.
