Abstract
A connector is mounted in a connector holder. A test section is moved toward the connector holder by turning a driving mechanism. When probes of the test section come into contact with terminals secured in a housing of the connector mounted in the connector holder, the connector is tested for continuity. If an overload force is applied to the probes during a continuity test, predetermined load breakaway members supporting rear ends of the probes are broken and the probes are moved backward away from the terminals, thereby preventing damage to the terminals or the probes. It is possible to carry out the continuity test again by exchanging the broken breakaway members with new ones.

A continuity test unit for a connector of a wire harness, the connector having a housing containing plural terminals, said continuity test unit comprising:
- a connector holder configured to hold a connector in position for testing the continuity of plural terminals contained in a housing of the connector;
- a test section configured to move forward toward and backward away from said connector holder, said test section including a detector opposed to the terminals contained in the housing of the connector held in said connector holder, and a block for supporting said detector;
- and
- a displacement device configured to move said test section relative to said connector holder between a test position in which said detector contacts the terminals and a release position in which said detector is spaced away from the terminals permitting loading and unloading of the connector from said connector holder;
- wherein said detector includes an outer sleeve mounted to said block and a contact end portion contained in and extending from said outer sleeve for contacting the terminals, said contact end portion being movable relative to said outer sleeve forward toward said connector holder and backward away from said connector holder;
- said test section further including a connecting member provided between said outer sleeve of said detector and said block, said connecting member interconnecting said detector and said block in such a manner that said detector is disconnected from said block when said detector is subjected to a predetermined load.
A continuity test unit for a connector having a housing containing plural terminals, said continuity test unit comprising:
- a connector holder configured to hold a connector in position for testing the continuity of plural terminals contained in a housing of the connector;
- a test section configured to move forward toward and backward away from said connector holder, said test section including a detector opposed to the terminals contained in the housing of the connector held in said connector holder, and a block for supporting said detector;
- and
- a displacement device configured to move said test section relative to said connector holder between a test position in which said detector contacts the terminals and a release position in which said detector is spaced away from the terminals permitting loading and unloading of the connector from said connector holder;
- said test section further including a breakaway element interconnecting said detector and said block for preventing said detector from moving relative to said block away from said connector holder, said breakaway element interconnecting said detector and said block in such a manner that said breakaway element ruptures and said detector is disconnected from said block when said detector is subjected to a predetermined load.
