rearwardly the use operation and function of the connector of fig8 10 is similar that of the connector of fig1 7 the prepared end of the cable is inserted into the bushing and pushed forwardly until cable the central conductor 14 fits into the pin 112 at this point the outer jacket bottoms on the rear radial face 72 a of the collar 66 a the non opaque retainer 24 a allows the user to visually confirm that the braided sleeve of the shield 18 and the jacket 20 have been fully inserted into the cavity between the retainer and the mandrel when the user has confirmed that the cable is fully inserted into the connector 10 a the bushing 26 a is compressed axially along the retainer 24 a until the position of fig1 is reached this is typically done with the aid of a tool as the bushing reaches the second closed position the back seal 100 of the bushing will engage the jacket 20 of the cable and pinch the jacket between the bushing and the barb 36 of the mandrel this prevents retraction of the cable from the connector also when the bushing moves to the second.
