Electrical connector having an improved metal shell

An electrical connector comprising:

• a terminal module including an insulative housing and a plurality of terminals integrally formed with the housing, said housing including a base portion and a tongue portion extending forwardly from the base portion, said terminals including contacting portions exposed upon the tongue portion;
• a metallic shielding shell attached upon the housing and including a metal main shell with a capsular configuration and a metal sub-shell fixed to the main shell and securing to the housing in a front-to-back direction without relative movement therebetween;
• a receiving room formed in the main shell to receive the tongue portion;
• a resisting protrusion formed on the main shell and extending into the receiving room;
• and
• a resisting groove formed in the base portion to receive the resisting protrusion;
• wherein
• the resisting protrusion forms a front edge extending beyond the base portion and outside of the resisting groove, and a rear edge spaced from a forward surface of the base portion in a rear end of the resisting groove so as not to directly transfer an excessive mating force along the front-to-back direction to the housing during mating.

An electrical connector comprising:

• a terminal module including an insulative housing and a plurality of terminals associatively disposed in the housing, said housing including a base portion and a tongue portion extending forwardly from the base portion, said terminals including contacting portions exposed upon the tongue portion;
• a metallic shielding shell attached upon the housing and including a metal main shell with a capsular configuration and a metal sub-shell fixed to the main shell and holding the housing in a front-to-back direction;
• a receiving room formed in the main shell to receive the tongue portion;
• a resisting protrusion formed on the main shell and extending into the receiving room;
• and
• a resisting groove formed in the base portion to receive the resisting protrusion;
