Abstract

A connector including a first connector element and a second connector element that are coupled into a single unit, in which the first connector element has an engagement projection that projects interior of the first connector element and extends in the direction of the depth of the first connector element so that the front end of the engagement projection is spacedly apart from the front edge of the first connector element, and the second connector element is formed with an engagement slit that extends in the direction of depth of the second connector element and engages with the engagement projection of the first connector element.

1. A connector comprising a first connector element and a second connector element that are coupled together, wherein
 said first and second connector elements are each formed with a metallic shell;  
 said first connector element is formed with an engagement projection that projects toward an interior of said first connector element and extends in a direction of depth of said first connector element, a front end of said engagement projection being spaced apart from a front edge of said connector element by a predetermined distance;  
 said engagement projection is formed by cutting a C-shape slit in a top surface of said metallic shell of said first connector element and bending a tongue formed downwardly, an engagement edge of the tongue extending by a first length in the direction of depth of said first connector element; and  
 said second connector element is formed with an elongated engagement slit in said metallic shell the elongated engagement slit having a second length that starts at a front edge of the metallic shell of the second connector element and extends in a direction of depth of said metallic shell of said second connector for engaging with said engagement projection formed in said metallic shell of said first connector element,  
   wherein, the engagement projection and the elongated engagement slit are configured such that when pushing the second connector element into the first connector element, the engagement edge of the tongue of the engagement projection engages the elongated engagement slit at the front edge of the metallic shell of the second connector element to provide for straight alignment, and wherein, the first length of the engagement edge of the tongue slides along the second length of the elongated slit to guide the sliding movement as the second connector element is pushed in the direction of depth and toward a rear of the first connector element.    
 
     
     
       2. The connector according to  claim 1 , wherein said engagement projection is provided at two locations of said first connector element so as to be parallel to side edges of said first connector element, and said elongated engagement slit is provided at two locations of said second connector element so as to be parallel to side edges of said second connector element and to correspond to said two locations of said engagement projections of said first connector element. 
     
     
       3. The connector according to  claim 1 , wherein said engagement projection has a predetermined length in said depth direction and said elongated engagement slit has a predetermined length in said depth direction which is at said predetermined length of said engagement projection. 
     
     
       4. An electrical connector system comprising:
   a first electrical connector including:      a body having a metallic top plate, a metallic bottom plate, a first side and a second side, the body having a width W 1  and a depth D 1 , wherein the first and second sides are smaller relative to the top and bottom plates providing a substantially flat body;        an array of electrodes extending in the direction of the depth D 1  inside the body; and        first and second projections, each projection being formed by cutting a C - shaped slit in the metallic top plate and bending a tongue formed downwardly, each projection longitudinally extending along the depth D 1 , the first and second projections being formed at about the same distance from the first side and the second side, respectively; and          a second electrical connector including:      a body having a metallic top plate, a metallic bottom plate, a first side and a second side, the body having a width W 2  and a depth D 2 , wherein the first and second sides are smaller relative to the top and bottom plates providing a substantially flat body;        an array of electrodes extending in the direction of the depth D 2 , the array of electrodes being positionally secured by insulating material to an interior surface of the body; and        first and second elongated slits formed on the metallic top plate of the body, the first and second elongated slits starting from a front edge of the metallic top plate and longitudinally extending in the direction of the depth D 2 , the first and second elongated slits being formed at about the same distance from the first side and the second side of the body, respectively,        wherein, the engagement projection and the elongated engagement slit are configured such that when inserting the second connector element into the first connector element, the engagement projection engages the elongated engagement slit to provide for straight alignment and to guide the sliding movement as the second connector element is pushed in the direction of depth and toward a rear of the first connector element.        
     
     
       5.
