Abstract

An electrical connector comprising an end portion of a flat circuit device which forms a connectively engaging protrusion on which a plurality of contacting terminals are arranged and a supporting board portion for supporting the connectively engaging protrusion, and first and second conductive shells having respectively first and second plate portions opposite to each other with the supporting board portion between, wherein the first conductive shell is attached to the supporting board portion with the first plate portion thereof covering directly a first surface of the supporting board portion and the second conductive shell is attached also to the supporting board portion with the second plate portion thereof covering directly a second surface opposite to the first surface of the supporting board portion, so as to hold the connectively engaging protrusion supported with the supporting board portion for causing the same to engage with a mating electrical connector.

Claims

1. An electrical connector comprising:

an end portion of a flat circuit device which forms a connectively engaging protrusion on which a plurality of contacting terminals are arranged and a supporting board portion for supporting the connectively engaging protrusion, and

first and second conductive shells having respectively first and second plate portions opposite to each other with the supporting board portion between,

wherein said flat circuit device has a board—

shaped insulating base on which said connectively engaging protrusions and said supporting board portion are provided and in which a plurality of strip—

shaped conductors are buried and arranged in parallel with each other and to form with end portions thereof respectively, said contacting terminals are arranged on said connectively engaging protrusion to expose to the outside of said board—

shaped insulating base for coming into contact directly and respectively with conductive contacts of a mating electrical connector,

wherein said first conductive shell is attached to said supporting board portion with said first plate portion thereof covering directly a first surface of said supporting board portion and said second conductive shell is attached also to said supporting board portion with said second plate portion thereof covering directly a second surface opposite to said first surface of said supporting board portion, so that said first and second conductive shells are operative to hold said connectively engaging protrusion supported by said supporting board portion at said end portion of said flat circuit device for causing the same to engage with said mating electrical connector in such a manner that said contacting terminals are exposed on said collectively engaging protrusion, and

wherein said first conductive shell is provided with a pressing tongue operative to come into press—

contact with an end surface provided between said first and second surfaces of said supporting board portion to be perpendicular to each of said first and second surfaces.

2. An electrical connector according to claim 1, wherein a part of a shielding conductor provided on the flat circuit device is exposed on the connectively engaging protrusion supported by the supporting board portion at the end portion of the flat circuit device.

3. An electrical connector according to claim 1, wherein the first conductive shell has first engaging portions provided respectively on both end portions thereof in a direction along which the contacting terminals are arranged, the second conductive shell has second engaging portions provided respectively on both end portions thereof in the direction along which the contacting terminals are arranged, and the first and second engaging portions are engaged with each other when the second conductive shell is attached to the first conductive shell.

4. An electrical connector according to claim 1, wherein each of the first and second conductive shells is formed independently.

5. An electrical connector according to claim 1 further comprising a manipulative lever mounted to be rotatable on the first conductive shell, said manipulative lever being provided with a pair of end portions each forming an axial portion held to be rotatable by one of end portions of the first conductive shell in the direction along which the contacting terminals are arranged and operative to be manipulated to rotate in regard to the first and second conductive shells to engage with the mating electrical connector so that the connective engaging protrusion and the mating electrical connector are maintained in mutual engagement.

6. An electrical connector according to claim 1 further comprising a connecting member for connecting the first and second conductive shells with each other to be incorporated and causing the first plate portion of the first conductive shell and the second plate portions of the second conductive shell to be opposite to each other.

7. An electrical connector according to claim 6, wherein a pair of connecting members are provided, each of said connecting members being operative to connect one of end portions of the first conductive shell in the direction along which the contacting terminals are arranged and one of end portions of the second conductive shell in the direction along which the contacting terminals are arranged with each other.
