Abstract

The pressure welding contact is provided with an electric wire connecting portion and a contact connecting portion. The electric wire connecting portion comprises a first fixing plate and a pressure welding piece. The pressure welding piece comprises a notched groove into which the core wire of the electric wire can be introduced. The contact connecting portion comprises a second fixing plate and an elastic piece. The second fixing plate contacts the first fixing plate. The elastic piece turns back from the base end portion of the second fixing plate. Further, the elastic piece is disposed in a state inclined upwards, towards the tip portion of the second fixing plate. The elastic piece comprises at its tip portion a contact point portion. The mating side connector can be inserted from between the second fixing plate and the elastic piece.

First claim

What is claimed is:

1. A pressure welding contact provided with an electric wire connecting portion for hard wiring by a pressure welding connection a terminal of an electric wire, and a contact connecting portion which is capable of connecting with a mating side contact, wherein
the electric wire connecting portion comprises
a strip-shaped first fixing plate on which the terminal of the electric wire can be mounted, and
a pressure welding piece continuous from a base end portion of the first fixing plate and rising from one face of the first fixing plate, and having a notched groove, into which a core wire of the electric wire can be introduced from an outer circumferential direction, notched towards the one face of the first fixing plate,

the contact connecting portion comprises
a strip-shaped second fixing plate which, in a state contacting another face of the first fixing plate from a tip portion of the first fixing plate, extends towards the pressure welding piece, and
an elastic piece which is continuous from a base end portion of the second fixing plate, and which turns back towards another face of the second fixing plate from one face of the second fixing plate, and which is provided with a tip portion including a contact point portion in a state which inclines upwards in a direction away from the other face of the second fixing plate towards a tip portion of the second fixing plate, and wherein

the pressure welding contact is maintained in a first housing with a hole opened in one end face, into which the mating side contact is insertable from between the tip portion of the second fixing plate and the tip portion of the elastic piece, towards the base end portion of the elastic piece.

2. A pressure welding contact according to claim 1 , wherein the pressure welding piece is provided above the second fixing plate between the base end portion and the tip portion of the second fixing plate, and in a perpendicular direction with respect to the one face of the first fixing plate.

3. A pressure welding contact according to claim 1 , wherein the pressure welding piece is joined by a notch which is easily separated from a tip edge thereof, to a side portion of a strip-shaped contact carrier, and this contact carrier, is joined to the pressure welding piece in a direction approximately perpendicular with respect to the direction in which the contact carrier extends.

4. A pressure welding connector provided with a rectangular solid-shaped first housing inside which one or more of the pressure welding contacts according to claim 1 are disposed, wherein
the first housing comprises
a first slot capable of accommodating the pressure welding contact hollowed out from one face of the first housing, where the elastic piece can be disposed to face a bottom face of the first slot,
a second slot which communicates with the first slot, into which the terminal of the electric wire can be introduced from an outer circumferential direction in an insulating covered state, and
one or more holes, opened on one end face adjoining the one face of the first housing, into which the mating side contact can be inserted towards a space between the tip portion of the second fixing plate and the tip portion of the elastic piece.

5. A pressure welding connector according to claim 4 , wherein the mating side connector consists of a pin-shaped connecting terminal, and
the mating side connector is provided with a rectangular solid-shaped second housing where one or more of the connecting terminals are disposed inside a recess portion opened at one face,
the first housing comprises
a header portion which is fittable in the recess portion, formed at one end side, and
a flange portion which is partially abuttable with one face of the second housing, formed at another end portion,

the second housing comprises a strip-shaped lock arm which is provided at a prescribed space from one inner wall of the recess portion and which projects from a bottom portion of the recess portion towards the open face of the recess portion and approximately parallel to the one inner wall of the recess portion, the lock arm being provided at its tip portion with a trapezoidal-shaped hook portion projecting towards a central portion of the recess portion, and
the first housing comprises one or more quadrangular frustum-shaped engaging protrusions which are capable of engaging and disengaging with the hook portion, protruding from one face of the header portion.

6. The pressure welding connector according to claim 5 , wherein the mating side connector comprises a lead terminal continuous with the connecting terminal, which can be solder-joined to a printed circuit board.

7. The pressure welding connector according to claim 6 , wherein at the mating side connector, the lead terminal is bent at an approximately right angle with respect to the connecting terminal.
