Abstract
A contact element of a plug-in connector in which the peeled portions of electric wires are inserted includes a substantially U-shaped conductive plate and a leaf-like spring member. The conductive plate is formed by bending and constituted by a proximal end portion having a plurality of electric wire insertion holes and long and short bent pieces bent at two edges of said proximal end portion. The leaf-like spring member has one end side caught by the long bent piece of the conductive plate and a plurality of strip-like tongue pieces that are to be engaged with the inner side of said short bent piece and extending obliquely from the other end side thereof toward the long bent piece.
Claims8
A plug-in connector comprising:
- a contact element constituted by a conductive plate having electric wire insertion holes in which peeled portions of a plurality of electric wires are inserted, and a leaf-like spring member integrally mounted on said conductive plate and having a plurality of tongue pieces for urging the inserted peeled electric wire portions against part of said conductive plate;
- and
- a holder for incorporating said contact element and made of a synthetic resin material having a heat-resistant insulating property, wherein
- said conductive plate forming a substantially C-shaped bend having a proximal end portion with a plurality of electric wire insertion holes and first and second bent pieces arranged at both sides of said proximal end portion,
- one end of said leaf-like spring member forming a bent piece and said bent piece of said leaf-like spring member hooked at the distal end outer side of the first bent piece of said conductive plate, the other end of the leaf-like spring member forming said plurality of tongue pieces,
- the leaf-like spring member further having folded portions formed between said bent piece of said leaf-like spring member and said tongue pieces, said folded portions engaging an inner side of said second bent piece, the plurality of said tongue pieces of the leaf-like spring member being formed between said folded portions and the end opposite said bent piece of said leaf-like spring member, said tongue pieces extending obliquely toward the distal end of said first bent piece for clamping said peeled portions of said electric wires under pressure on the first bent piece of said conductive plate,
- said leaf-like spring member integrally mounted on said conductive plate as a unit of the contact element, said folded portions being embraced and held by said second bent piece and said peeled portions of said electric wires capable of insertion, from the direction which is almost opposite to the power direction working on said folded portions through said tongue pieces.
