Abstract

An electric connector suitable for establishing electrical connection between a wire and a mating connector or between a wire and another wire comprising: means forming a body, the means including contact means, the contact means having a first end for receiving a wire and a second end for making an electrical connection with the mating connector or for receiving another wire; plate means mountable on the body and forming a plurality of guide channels for wire and guide slots for receiving slidable cam means; means for retaining the plate means on the means forming a body; and slidable cam means slidably positioned in the receiving means, and slidable between a first position adjacent said means for piercing insulation and a second position remote therefrom, whereby a wire may be inserted into the guide channels when the cam means is in the second position and can be forced by said cam means into engagement with said means for piercing insulation on a wire by moving the cam means to the first position.

Claims

1. An electric connector suitable for establishing electrical connection between a wire and a mating connector comprising;

means forming a body, said means including contact means, said contact means having a first end for receiving a wire and a second end for making an electrical connection with said mating connector, the first end of said contact means including means for piercing insulation on a wire;

plate means mountable on said body and forming a plurality of guide channels, said guide channels being adapted to allow insertion of a wire into said connector such that said wire contacts said contact means, said plate means further forming guide slots for receiving slidable cam means;

means for retaining said plate means on said means forming a body; and

slidable cam means slidably positioned in said receiving means, and slidable between a first position adjacent said means for piercing insulation and a second position remote therefrom, whereby a wipe may be inserted into said guide channels when said cam means is in said second position and can be forced by said cam means into engagement with said means for piercing insulation on a wire by moving said cam means to said first position.

2. A wire connector for connecting a plurality of insulated wires with electric contact members, said electric contact members each having a terminal socket end to be connected with a pin and a projection to be connected with a wire, said wire connector comprising;

a main body comprising a socket portion having pin receiving cavities in which the terminal socket ends of the electric contact member are inserted respectively, and a central plate being formed with slots for mounting the electric contact members on upper and lower surfaces thereof respectively;

slider guide plates being mounted on the upper and lower surfaces of said central plate of the main body, and each said guide plate having slider seating holes for receiving each slidable cam means and channels for inserting each wire into the inside of the wire connector assembled;

outer covers being mounted to cover the slider guide plates respectively and each cover having slider slots for receiving a tab associated with the slidable cam means; and

the slidable cam means being slidably installed under said each outer cover between a wire locking position in which the electrical connection of the wire and the electric contact member is made and a wire unlocking position which no electrical connection thereof is made.

3. A wire connector according to the claim 2, wherein each said slidable cam means comprises slider is provided with a tab and a stop on one side, and a cam portion and a flat tail portion on another side, and wherein each slider slot has a through hole portion, a first land portion having a stop groove, and a second land portion, whereby in the wire looking position the tail portion of the slider can be engaged between the surface of the second land portion and an outer surface of the slider guide plate, and the stop is engaged with the stop groove of the slider slot in the outer cover, and in the wire looking position the cam portion pushes the wire down into the projection of the electric contact member so that the insulation of the wire is pierced by the projection of the electric contact member and thus the electrical connection is made.

4. A wire connector according to the claim 3, wherein the sides of the cam portion are tapered inward toward one another so that the cross sections thereof narrow toward a bottom surface which contacts the wire.

5. A wire connector according to the claim 2, wherein the slider guide plates are provided with holding blocks, wherein the outer covers have partition walls, each partition wall being inserted between said holding blocks, and wherein the channels are extended from said slider seating holes between said holding blocks, respectively.

6. A wire connector according to claim 2 wherein the central plate of the main body is formed with holes on the front thereof, and the slider guide plates are provided with the protrusions which engage with said holes;

and wherein the slider guide plates are provided with concave portions and pins, and the outer covers have walls which engage with said concave portions, and holes which engage said pins.

7. A wire connector for connecting a plurality of insulated wires with electric contact members for use in electronic circuits, said wire connector comprising:

electric contact members each having at least two projections and adapted to be connected with a wire adjacent opposed ends thereof;

a main body in the form of a plate being formed with slots for mounting the electric contact members on a surface thereof;

a slider guide plate mounted on the surface of the main body, and having slider seating holes for receiving sack slider and channels for inserting each wire into the inside of the wire connector assembled;

an outer cover being mounted to cover the slider guide plate and having slider slots for receiving the tab of the slider; and

sliders being slidably mounted under said outer cover and movable between a wire locking position in which the electrical connection of the wire and the electric contact member is made and a wire unlocking position in which the wire may be removed.

8. A wire connector according to the claim 7, wherein the slide guide plate is provided with holding blocks in both sides, wherein the outer cover has partition walls in both sides, each partition wall being inserted between said holding blocks, and wherein the channels are extended from said slider seating holes between said holding blocks, respectively.

9. A wire connector according to the claim 7, wherein said body is formed with holes on the surface thereof, and the slider guide plate is provided with the protrusions which engage with said holes, and wherein the slide guide plate is provided with pins, and the outer cover has holes which engage said pins.

10. A wire connector according to the claim 7, wherein each said slider is provided with a tab and a stop on one side, and a cam portion and a flat tail portion on the other side, and the both sides of the cam portion are tapered so that the cross sections thereof are narrowed toward the bottom surface which contacts with the wire, wherein each slider slot has a through hole portion, a first land portion having a stop groove, and a second land portion, whereby in the wire locking position the tail portion of the slider can be engaged between the surface of the second land portion and the outer surface of the slider guide plate, and said stop is engaged with said stop groove of the slider slot in the outer cover, and in the wire locking position the cam portion pushes the wire down into the projection of the electric contact member so that the insulation of the wire is pierced by the projection of the electric contact member and the electrical connection is made.

11. A wire connector according to the claim 10, wherein electric contact member is formed to include at least two projections in each end, the bottom surface of said each cam portion associated with said each end is formed to be flat and elongated so that said cam portion pushes down and connects the wire simultaneously to said projections.
