Abstract
Abstract A connector means includes a connector housing provided with a plurality of bores which is defined by a pair of plastic bases (1) each having a plurality of hemicycle grooves (2) each of which has an inner diameter 1 to several µm larger than an outer diameter of each of optical cables (3) to be connected. After the optical fibres are inserted into the respective bores and secured therein, one end surface of the connector housing is polished. A pair of connected housings (12, 13) are retained so that the polished end surfaces abut on each other thereby to attain a connection between a plurality of optical cables.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
101 words
A flat type plastic connector means for splicing a plurality of optical fibres, said connector means comprising: a pair of plastic bases each having one surface thereof on which a plurality of hemicycle grooves are formed, each of said grooves having an inner diameter 1 to several µm larger than an outer diamter of the optical fibre to be connected, said bases being adapted to clamp each pair of optical fibres having polished end surfaces between the respective said grooves so that said end surfaces connect to each other; and a retainer means for maintaining said bases in a clamped state.
Claim 2
Dependent Claim
101 words
A flat type plastic connector means for splicing a plurality of optical fibres, said connector means comprising: a pair of plastic bases each having one surface thereof on which a plurality of hemicycle grooves are formed, each of said grooves having an inner diameter 1 to several µm larger than an outer diamter of the optical fibre to be connected, said bases being adapted to clamp each pair of optical fibres having polished end surfaces between the respective said grooves so that said end surfaces connect to each other; and a retainer means for maintaining said bases in a clamped state.
Claim 3
Dependent Claim
31 words
A flat type plastic connector means according to Claim 1, wherein a bonding agent is applied into the grooves in said plastic bases to clamp and bond said optical fibres therein.
Claim 4
Dependent Claim
152 words
A flat type plastic connector means for splicing a plurality of optical fibres, said connector means comprising: two pairs of plastic bases each of which has one surface on which a plurality of hemicycle grooves are formed, each of said grooves having an inner diameter 1 to several pm larger than an outer diameter of an optical fibre to be connected, wherein surfaces of said bases having said grooves are coated with a bonding agent to secure an end portion of said optical fibre in the respective bores defined in a connector housing fromed by said pair of plastic bases through clamping and bonding each other, and end surfaces of said optical fibres projected from one end of said housing are polished so as to align with said one end of the respective housings one ends are then joined to each other thereby to connect said end surfaces of both optical fibres.
Claim 5
Dependent Claim
152 words
A flat type plastic connector means for splicing a plurality of optical fibres, said connector means comprising: two pairs of plastic bases each of which has one surface on which a plurality of hemicycle grooves are formed, each of said grooves having an inner diameter 1 to several pm larger than an outer diameter of an optical fibre to be connected, wherein surfaces of said bases having said grooves are coated with a bonding agent to secure an end portion of said optical fibre in the respective bores defined in a connector housing fromed by said pair of plastic bases through clamping and bonding each other, and end surfaces of said optical fibres projected from one end of said housing are polished so as to align with said one end of the respective housings one ends are then joined to each other thereby to connect said end surfaces of both optical fibres.
