Electrical connector

An electrical connector comprising a feeding connector half and a receiving connector half, wherein said feeding connector half comprises:

• a case having a front half potion and a rear half portion;
• a connector main body slidably mounted within said front half portion of said case, said connector main body having terminal accommodating cavities for housing a plurality of terminals;
• a compression coil spring surrounding said connector main body for urging said connector main body of said feeding connector half toward said receiving connector half;
• a handle including a main body portion and a slider, wherein said slider is slidably mounted in a drilled hole in a partition wall within said case for causing said connector main body to slide;
• a rotatable lever having a working portion, an intermediate portion and an operating portion, said intermediate portion being between said working portion and said operating portion, said working portion being rotatably attached to one end of said handle within said case and said operating portion projecting out of said case;
• said slider having radially extending shaft holes in a circumferential wall thereof and said working portion of said rotatable lever including a pair of supporting pieces forming a forked portion at a tip thereof such that said slider is placed between said pair of supporting pieces, said pair of supporting pieces having shaft holes corresponding to said shaft holes on said circumferential wall of said slider so that pins with narrow channels at front ends of said pins are inserted into said shaft holes of said supporting pieces when said slider is put between said pair of supporting pieces and stop rings are mounted through said supporting pieces and an outer periphery of said slider to said narrow channels;
• a preliminary locking means comprising a pair of locking arms rotatably attached in said case, said locking arms each having a hook-shaped locking claw at a front end of said locking arms, said hook-shaped locking claws outwardly projecting so as to engage locking channels of said receiving connector half and wire springs adjacent to each of said locking arms for urging said hook-shaped locking claws outwardly into engagement with said locking channels of said receiving connector half;
• and
• a secondary locking means attached to said handle and adjacent to said rotatable lever for locking and unlocking said rotatable lever wherein said rotatable lever is locked after said feeding connector half and said receiving connector half are preliminarily locked to each other and then said rotatable lever is rotated to a position where said operating portion of said rotatable lever is rotated towards and near said handle so that said feeding connector half is completely locked to said receiving connector half.

• and
• said secondary locking means for locking and unlocking said rotatable lever comprising:
• a locking concave portion on an outer periphery of said working portion of said rotatable lever;
• a releasing lever rotatably attached within said case, said releasing lever having an operating portion at a front end portion thereof and said operating portion of said releasing lever having a locking claw at a front end thereof;
• and
• a plate spring means for urging said front end portion of said releasing lever towards said rotatable lever, wherein said rotatable lever is locked when said locking concave portion in said working portion of said rotatable lever engages said locking claw of said operating portion of said releasing lever and wherein said rotatable lever is unlocked when said locking concave portion in said working portion of said rotatable lever is disengaged from said locking claw of said operating portion of said releasing lever.
