First Claim
1. An electric jack for receiving a plug to form an electric connection therebetween comprising:
- a main body made of electrically insulating material and having a central hole extending in a first direction, said plug being insertable into the central hole, a plurality of contact strip-clamping recesses extending in a second direction perpendicular to said first direction, a window portion through which contact strip-receiving portions are communicated with said central hole, and a plurality of contact strip-fitting holes each communicated with respective contact strip-clamping recesses; and
a plurality of contact strips each being made of a metal plate and having;
a fitting portion which is inserted into said contact strip-fitting hole of the main body;
a contact portion which has a width only slightly narrower than the width of the recess so that each contact strip is clamped in said contact strip-clamping recess of the main body, a part of the contact portion being projected into said central hole through said window portion; and
at least one end portion being the only portion of the contact strip exposed out of the main body so that a remaining substantial portion of the contact strip is embedded in the recess.

Abstract
An electric jack for receiving a plug to form the electric connection therebetween includes a main body made of electrically insulated resin and a plurality of movable contact strips. The main body has formed therein; a central hole through which the plug is insertable in an axial direction; a plurality of contact strip-clamping recesses extending in a direction perpendicular to the axial direction, the recesses being arranged in parallel with each other in the axial direction; a plurality of contact strip-fitting holes each being communicated with respective recesses; and a window portion through which the recesses are communicated with the central hole. The movable contact strip has a fitting portion to be inserted into the fitting hole of the main body and a contact portion to be clamped into the recess of main body. When the movable contact strip is inserted into the main body, the contact portion of movable contact strip is partially projected into the central hole through the window portion.
