Abstract

A connector terminal checking tool including a base, a connector receiving member fixedly provided on one end portion of the base for receiving a connector to be checked, and a connector checking member movably provided on the other end portion of the base in opposed relationship to the connector receiving member. The connector checking member includes a plurality of check terminals adapted to be electrically connected to a plurality of terminals disposed in a connector housing of the connector to form a closed circuit when the connector is received into the connector receiving member, whereby breaking of the terminals of the connector is checked. The connector receiving member is cooperatively provided with means for detecting projection of a terminal locking spacer mounted in the connector housing of the connector projecting from a side surface or a back surface of the connector housing, wherein when the connector is received into the connector receiving member, incomplete mounting of the spacer in the connector is detected by the detector.

Claims

1. A connector terminal checking tool comprising:

a base,

a connector receiving member fixedly provided on one end portion of said base for receiving a connector to be checked, and

a connector checking member movably provided on the other end portion of said base in opposed relationship to said connector receiving member, said connector checking member including a plurality of check terminals adapted to be electrically connected to a plurality of terminals disposed in a connector housing of said connector to form a closed circuit when said connector is received into said connector receiving member, whereby electrical disconnection of said terminals of said connector is checked;

characterized in that said connector receiving member further comprises detecting means for detecting projection of a terminal locking spacer mounted in said connector housing of said connector projecting from a side surface or a back surface of said connector housing.

2. The connector terminal checking tool as claimed in claim 1, wherein said detecting means comprises a detecting pin adapted to retractably abut against said spacer and a warning or indicating circuit is adapted to be operated when said detecting pin is retracted by said spacer.

3. The connector terminal checking tool as claimed in claim 1, wherein said detecting means comprises a detecting pin adapted to retractably abut against said spacer and a pivotable lock arm engaging with said detecting pin at one end thereof, wherein when said detecting pin is retracted by said spacer, said lock arm is pivoted to stop movement of said connector checking member toward said connector received in said connector receiving member.

4. The connector terminal checking tool as claimed in claim 3, herein said lock arm is provided at the other end thereof with a microswitch adapted to contact said connector checking member when said detecting pin is retracted by said spacer to pivot said lock arm, and further comprising a warning or indicating circuit adapted to be operated by said microswitch.

5. The connector checking tool as claimed in claim 1, wherein said connector receiving member comprises a fixed wall for receiving said connector, a cover wall for openably closing said fixed wall, and a pair of contactors provided on said fixed wall and said cover wall and adapted to contact with each other when said cover wall is fully closed with respect to said fixed wall, and further comprising a warning or indicating circuit adapted to be operated by said contactors.
