Plug connector

An electrical connector comprising:

• a plug connector element having a first metallic shell and adapted to be coupled to a receptacle connector element having a second metallic shell, the first shell comprising a top plate, a bottom plate, a first side and a second side and having a width W and a depth D, the first and second sides being small relative to the top and bottom plates making the first shell substantially flat;
• first and second engagement slits formed in the top plate of the first shell, the first and second engagement slits starting from a front edge of the top plate and extending in a direction of the depth D;
• an array of electrodes positioned within the first shell extending in a direction of the depth D between the first and second engagement slits such that there are no electrodes between an engagement slit and its respective side, the array of electrodes being positionally secured by insulating material to an interior surface of the bottom plate of the first shell, leaving an insertion cavity in the interior of the shell between the array of electrodes and the top plate;
• wherein the first and second engagement slits in the first shell are adapted to engage with first and second engagement projections of the receptacle connector element that project toward an interior of the receptacle connector element and extend in a direction of a depth of the receptacle connector element, a front end of the first and second engagement projections being spaced apart from a front edge of the receptacle connector element by a predetermined distance, the engagement projections being formed by cutting a C-shape slit in a top surface of the second shell and bending a tongue formed downwardly.

• first and second engagement slits formed in the top plate of the first shell, the first and second engagement slits starting from a front edge of the top plate and extending in a direction of the depth D;
• an array of electrodes positioned within the first shell extending in a direction of the depth D between the first and second engagement slits such that there are no electrodes between an engagement slit and its respective side, the array of electrodes being positionally secured by insulating material to an interior surface of the first shell, leaving an insertion cavity in the interior of the shell between the array of electrodes and the top plate;
• wherein the first and second engagement slits in the first shell are adapted to engage with first and second engagement projections of the receptacle connector that project towards an interior of the receptacle connector element and extend in a direction of depth of the receptacle connector element.

An electrical plug connector comprising:

• a body having a top plate, a bottom plate, a first side and a second side, the body having a width W and a depth D, wherein the first and second sides are smaller relative to the top and bottom plates providing a generally flat body;
• first and second engagement slits formed on the top plate of the body and extending from a front edge of the top plate in a direction of depth D for engaging with engagement projections formed in a body of a corresponding receptacle side connector element;
• an array of electrodes positioned within and extending in the direction of the depth D of the body between the first and second engagement slits such that there are no electrodes between an engagement slit and its respective side, the array of electrodes being positionally secured by insulating material to an interior surface of the bottom plate of the body, leaving an insertion cavity in the interior of the body between the array of electrodes and the top plate;
• wherein the first and second engagement slits facilitate insertion alignment when the plug connector mates with a corresponding receptacle connector by mating with engagement projections that project toward an interior of the receptacle connector and extend in a direction of depth of the receptacle connector.

An electrical plug connector comprising:

• a body having a top plate, a bottom plate, a first side and a second side, the body having a width W and a depth D, 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, the array of electrodes being positionally secured by insulating material to an interior surface of the body;
• a retention mechanism formed on the body and operable to provide secure engagement between the plug connector and a corresponding receptacle connector when the plug connector mates with the corresponding receptacle connector, wherein the retention mechanism comprises at least one raised springy holder raised outwardly from a plate of the body, the raised springy holder providing compressive action when the plug connector mates with a corresponding receptacle connector;
• and
• first and second slits formed on the top plate of the body extending in the direction of the depth D, the first slit being formed at a distance S1 from the first side and the second slit being formed at a distance S2 from the second side,
• wherein the array of electrodes is disposed between the first and second slits such that there are no electrodes between a slit and its respective side, and
• wherein the first and second slits facilitate insertion alignment when the plug connector mates with a corresponding receptacle connector.
