Abstract

A connector terminal checking device of the present invention comprises a base plate, a checking body movably mounted on the base plate, and a connector holder fixed onto the base plate, wherein the checking body further comprises a plurality of check pins aligned facing toward the connector holder, and the connector holder is provided with a terminal holding wall formed with a plurality of terminal position regulating sections, each for receiving a corresponding one of a plurality of terminal accommodating chambers of a connector to be checked, and also provided with a pair of connector sustainers shiftably urged by way of a resilient stuff, wherein by shifting the checking body toward the connector installed in the connector holder to bring the terminals in the connector into contact with the check pins, the terminals improperly inserted in the accommodating chamber are abutted against the terminal position regulating section and shifted to the properly inserted position.

Claims

1. A connector terminal checking device comprising a base plate, a checking body movably mounted on the base plate, and a connector holder fixed onto the base plate, wherein said checking body further comprises a plurality of check pins aligned facing toward said connector holder, and said connector holder is provided with a terminal holding wall formed with a plurality of terminal position regulating sections, each for receiving a corresponding one of a plurality of terminal accommodating chambers of a connector to be checked, and also provided with a pair of connector sustainers shiftably urged by way of a resilient stuff, wherein by making said checking body approach to the connector installed in said connector holder to bring the terminals in the connector into contact with said check pins to be electrically connected, and also shifting the connector thereby, the terminals improperly inserted in the accommodating chamber are abutted against said terminal position regulating section and shifted to the properly inserted position.

2. A connector terminal checking device as claimed in claim 1, each of said terminal position regulating sections is formed in a groove-like shape formed in said terminal holding wall, and each of said connector sustainer is provided with a pair of slide pins, each inserted in a corresponding one of slide pin receiving holes formed in said terminal holding wall, wherein each said connector sustainer is urged by a spring provided in each of said pin receiving holes.

3. A connector terminal checking device as claimed in claim 2, wherein said pair of slide pins are vertically aligned with each other in parallel with a pair of rails mounted on said base plate along which said checking body is moved back and forth.

4. A method of checking connector terminals by use of a connector terminal checking device comprising a base plate, a checking body movably mounted on the base plate and having an operation lever, and a connector holder fixed onto the base plate, wherein said checking body further comprises a plurality of check pins aligned facing toward said connector holder, and said connector holder is provided with a terminal holding wall formed with a plurality of terminal position regulating sections, each for receiving a corresponding one of a plurality of terminal accommodating chambers of a connector to be checked, and also provided with a pair of connector sustainers shiftably urged by way of a resilient stuff,

said method comprising the steps of:

installing a connector terminal to be checked within said connector holder;

rotating said operation lever to make said checking body approach to the connector in said connector holder and bring the terminals in the connector into contact with said check pins to be electrically connected,

shifting the connector thereby, and

bringing the terminals improperly inserted in the accommodating chamber, if any, to be abutted against said terminal position regulating section and shifted to the properly inserted position.
