Abstract

A connector of a simple structure adapted to absorb a positional deviation which occurs when a plug and a receptacle are fitted into each other, without spoiling the strength of the connector is provided. The connector has a plug, and a receptacle into which the plug is fitted. A receptacle housing holding receptacle contacts and formed out of an insulating material is provided with projecting portions extending in the direction crossing the fitting direction. A plug housing holding plug contacts is provided with wall portions having recesses which extend in the fitting direction, and which are capable of having the projecting portions provided on the receptacle housing engaged therewith. The width of the projecting portions is smaller than that of the recesses, and the receptacle engaged with the plug housing swings in the direction crossing the fitting direction to absorb a deviation of the position of the connector.

Claims

1. A connector comprising:

a plug, the plug having;

a plurality of plug contacts, each plug contact having a plate contact portion; and

a plug housing for holding the plug contacts, the plug housing having a wall portion and a recess; and

a receptacle, the receptacle having;

a plurality of receptacle contacts, each receptacle contact having a bifurcated holding portion; and

a receptacle housing for holding the receptacle contacts, the receptacle housing having a projecting portion;

wherein the plug contacts and the receptacle contacts correspond so as to be engageable and form electrical connections when the plug is inserted into the receptacle;

wherein the projecting portion of the receptacle housing protrudes outward and extends parallel to a direction of insertion of the plug into the receptacle;

wherein the wall portion of the plug housing extends in the direction of insertion of the plug into the receptacle;

wherein the recess of the plug housing is engageable with which the projecting portion of the receptacle housing;

wherein the width of the projecting portion of the receptacle housing is smaller than the width of the recess of the plug housing; and

wherein the bifurcated holding portion is substantially orthogonal to the contact portion so as to grasp the surfaces of the contact portion, the plug housing further comprising;

a first plug housing member and a second plug housing member; and

each of the plug contacts further comprising;

a plug leg portion and a connecting portion;

wherein the second plug housing member is disposed inside of the first plug housing member away from the first plug housing member, and the second plug housing member has the wall portion and the recess;

wherein a part of the contact portion of the plug contact is embedded in the second plug housing member;

wherein a part of the plug leg portion of the plug contact is embedded in the first plug housing member; and

wherein the connecting portion connects the contact portion and the plug leg portion for connecting the first plug housing member and the second plug housing member.

2. A connector comprising:

a plug, the plug having;

a plurality of plug contacts, each plug contact having a plate contact portion; and

a plug housing for holding the plug contacts, the plug housing having a wall portion and a recess; and

a receptacle, the receptacle having;

a plurality of receptacle contacts, each receptacle contact having a bifurcated holding portion; and

a receptacle housing for holding the receptacle contacts, the receptacle housing having a projecting portion;

wherein the plug contacts and the receptacle contacts correspond so as to be engageable and form electrical connections when the plug is inserted into the receptacle;

wherein the projecting portion of the receptacle housing protrudes outward and extends parallel to a direction of insertion of the plug into the receptacle;

wherein the wall portion of the plug housing extends in the direction of insertion of the plug into the receptacle;

wherein the recess of the plug housing is engageable with which the projecting portion of the receptacle housing;

wherein the width of the projecting portion of the receptacle housing is smaller than the width of the recess of the plug housing;

wherein the bifurcated holding portion is substantially orthogonal to the contact portion so as to grasp the surfaces of the contact portion;

wherein the recess extends to a front edge of the wall portion; and

wherein the death of the recess increasing toward the front edge of the wall portion,

the plug housing further comprising;

a first plug housing member and a second plug housing member; and

each of the plug contacts further comprising;

a plug leg portion and a connecting portion;

wherein the second plug housing member is disposed inside of the first plug housing member away from the first plug housing member, and the second plug housing member has the wall portion and the recess;

wherein a part of the contact portion of the plug contact is embedded in the second plug housing member;

wherein a part of the plug leg portion of the plug contact is embedded in the first plug housing member; and

wherein the connecting portion connects the contact portion and the plug leg portion for connecting the first plug housing member and the second plug housing member.
