Abstract
An electrical connection terminal arrangement has a housing (1) of insulating material, in which at least one slit-blade insulation-piercing contact is located that is formed on a contact spring (17). The contact spring is additionally provided with at least one plug contact (27) and one apparatus connection contact (29).
Claims17
An electrical connection terminal arrangement having a housing of insulating material, which has at least one insertion slit, open at an edge toward one insertion side for an electric wire and at least one slit-blade insulation-piercing connector located in the housing,
- said slit-blade insulation-piercing connector (17) having two connector legs (16, 16a) and a slit-blade insulation-piercing slit (15, 15a) open at the edge and aimed at the insertion slit for an electric wire connection formed between said connector legs (16, 16a), at least portions of said legs (16, 16a) adjacent said insulation-piercing slit (15, 15a) forming a contact zone,
- wherein the slit-blade insulation-piercing connector is formed on a contact spring (17, 17a),
- wherein
- the contact spring (17, 17a) additionally has at least one plug-in contact (27, 28;
- 27a);
- a contact (29, 70a, 71a) for an accessory apparatus connection;
- and
- a groove-like indentation (20, 21;
- 20a, 21a) formed on at least one side in a portion of the housing (1) receiving the slit-blade insulation-piercing connector (17) adjoining the insertion slit (11, 11a), which is deeper and wider than said insulation-piercing slit (15, 15a), and positioned closely adjacent said insulation-piercing connector (17),
- the length, depth and width of said indentation (20, 21;
- 20a, 21a) being dimensioned such that a cut end of the electric wire placed therein is received within the indentation in an electrical shock-hazard proof manner;
- wherein the housing is formed with at least one chamber (24, 25) located beneath the groove-like indentation (20, 21;
- 20a, 21a) and having at least one access opening (36, 43) at a face of the housing;
- wherein at least one of the plug-in contacts (27, 28;
- 27a) and the accessory apparatus connection contact (29, 70a, 71a) is located in said at least one chamber below the slit-blade insulation-piercing connector (17) and the slit-blade insulation-piercing slit (15, 15a) thereof;
- and
- wherein the accessory apparatus connection includes at least one base pin (70a, 71a) protruding from the housing.
