Connector engaging structure
First Claim
1. A connector engaging structure comprising:
- a first connector including;
a base portion secured to an electronic device;
connector terminals fixedly secured to said base portion;
a cylindrical wall protruding from said base portion and surrounding said connector terminals, said cylindrical wall having an engaging groove formed in one end portion thereof, anda locking protrusion formed on one end portion of an outer side surface of said wall; and
a second connector includingan inner housing includingconnector terminals which are electrically connectable to said connector terminals of said first connector, anda lock arm which, when said second connector is engaged with said first connector, engages with said engaging groove, andan outer housing which is slidable on the outer surface of said inner housing in a direction of engagement, said outer housing having a cantilevered arm which, when said second connector is engaged with said first connector, is locked to said locking protrusion, wherein said inner housing has a cantilevered arm push-up protrusion at one end thereof which releases the locking of said cantilevered arm to said locking protrusion during engagement.

Abstract
A connector engaging structure which prevents male and female connectors from being insufficiently engaged with each other, and which positively prevents the connector housing from being damaged. The connector engaging structure 1 is designed as follows. In engaging a second connector 3 with a first connector 2, a cantilevered arm 44 formed in an outer housing, which is a part of the second connector, is locked to a locking protrusion 16 of the first connector. Next, a locking arm 25 forming an inner housing 21, which is a part of the second connector 3, is engaged with an engaging groove 15 formed in the first connector 2. With the outer housing 22 moved by the elastic force of a spring member 35, the lock arm 25 is held down so that the first and second connectors are completely engaged with each other.

4. A connector engaging structure, comprising:
-
a first connector including a base portion secured to an electronic device; connector terminals fixedly secured to said base portion; a cylindrical wall protruding from said base portion and surrounding said connector terminals, said cylindrical wall having an engaging groove formed in one end portion thereof; and a locking protrusion formed on one end portion of an outer side surface of said wall; and a second connector engageable with said first connector by movement in an insertion direction, said second connector including an inner housing;
an outer housing in which said inner housing is slidably disposed; and
a spring interposed between said inner and outer housing for urging said inner housing in a direction opposite said insertion direction,wherein said inner housing includes connector terminals which are electrically connectable to said connector terminals of said first connector;
a lock arm which, when said second connector is engaged with said first connector, engages with said engaging groove; and
a push-up projection,wherein said outer housing includes a cantilevered arm which, when said second connector is completely engaged with said first connector, is climbed over said locking protrusion, wherein when said second connector is initially moved a predetermined distance in said insertion direction, said cantilevered arm abuts against said locking protrusion to thereby prevent further movement of said outer housing with respect to said inner housing in said insertion direction causing said spring to urge said inner housing in said opposite direction, and wherein further movement of said inner housing in said insertion direction causes said push-up projection to deflect said cantilevered arm beyond said lock protrusion allowing said outer housing to move in said insertion direction such that said cantilered arm engages said locking protrusion. - View Dependent Claims (5, 6, 7)

8. A connector engaging structure, comprising:
-
a first connector secured to an electronic device, said first connector including a base portion and a plurality of first terminals extending from said base portion; a second connector engageable with said first connector by movement in an insertion direction, said second connector including; an inner housing having a plurality of second terminals and including a locking arm which is engageabe with an engaging groove provided in said first connector, an outer housing slidably disposed with respect to said inner housing, said outer housing abutting against said locking arm when said inner housing is completely engaged with said first connector to prevent disengagement of said locking arm from said engaging groove, a spring interposed between said inner and outer housings for urging said inner housing in a direction opposite said insertion direction, preventing means for preventing said outer housing from moving in said insertion direction as said inner housing is moved a predetermined distance in said insertion direction such that said spring urges said inner housing in said oppposite direction, said preventing mean including a cantilevered arm extending from said outer housing and engaging said first connector, and disengaging means for disengaging said cantilevered arm from said first connector when said inner housing continues to move in said insertion direction thereby allowing said outer housing to move in said insertion direction to a locked position at which said outer housing abuts against said locking arm. - View Dependent Claims (9)
