Contact Retention Test Tooling

RUSSTECH's unique RTCRT ™ contact retention tools are used to test the assembly status of crimp-type removable contacts in a broad range of connector types.
Each tool features a double ended test probe that can test both pin and socket contacts. A patented, preset release mechanism leaves contacts unharmed yet forces them out of the connector if they are not properly inserted. This mechanism is factory set with precision test force and is not user adjustable.

In operation, the RTCRT  tester quickly pre-loads the contact with the test force and then releases if the contact is properly seated. The RTCRT is held in alignment with the connector, with the probe touching the contact to be tested.  The tool is then pushed towards the connector.  If the contact is properly assembled and locked in, the tool gives an audible and physical “click” when the preset load pressure is reached.  Immediately following, the wing stop on the face of the tool bottoms out on the rim of the connector shell and leaves the contact unharmed and intact.  If the contact latching clip is faulty or the contact was not inserted properly, the tool will automatically bottom out on the connector shell and at the same time, force the contact partially out of the connector, giving the user a good visual indication of the faulty contact.  During this cycle, no “click” will be felt or heard as the pre-load has not been reached.

A unique safety feature of the RTCRT tool is the "wing Stop" located at the front of the tool. In addition to aiding in tool alignment, our "Wing Stop" prevents any additional tool travel after the contact has been tested. This feature also allows us to control the probe length / wing stop relationship, so should you find an unseated contact, the RTCRT test probe will push it back as far as the interfacial seal and the wing stop will prevent the test probe from entering the contact cavity.
