Connector having an floatable optical module

A connector comprising:

• an insulative housing having a receiving slot formed therein, a cavity at rear of the receiving slot and communicating with the receiving slot, and a resisting block located under the cavity and extending slantwise backwardly and upwardly in the cavity;
• a plurality of contacts retained in the insulative housing;
• an optical module for transmitting optical data and being movably received in the receiving slot along a front-to-back direction;
• and
• a compression coil spring sandwiched between the insulative housing and the optical module, and having a front end for biasing the optical module forwardly and a rear end for being resisted upwardly by the resisting block.

An electrical connector comprising:

• an insulative housing defining a receiving slot;
• a cavity communicatively located behind the receiving slot;
• an optical module received in the receiving slot and back and forth moveable along a front-to-back direction;
• a pole unitarily rearwardly from a rear end of the optical module;
• and
• a coil spring located behind the optical module with a front end surrounding the pole, and a rear end received in the cavity;
• wherein
• a rearward upward wedge structure is formed in the cavity for allowing the rear end the coil spring to move thereon during compression of the coil spring due to mating with a complementary connector so as to assure the front end of the coil spring is forced toward the housing for efficiently retaining the optical module in the receiving slot in a floating manner.
