A testing device such as a network analyzer is joined to a test unit, such as a circulator, by an electrical precision test connector 1 having an electrical conductor 2 with conductive end portions 34 and 40, a hollow, bipartite shell 3 and a dielectric insert 4 as part of the conductor 2, the electrical conductor 2 further comprising a flexible, slotted contact end portion 24 with flat, opposing contact surfaces 36 and 37 with the slotted end portion being pinched 38 for a slideable, clamping engagement, above and below, with an inserted tab connector and the hollow, bipartite shell 3 having an end contact surface 24 and being spring biased to provide complete electrical contact with a corresponding portion of the test unit 54 during connection. The test connector 1 is characterized by a rear contact surface 24 having substantially a square profile with four flats 59, each disposed at ninety degrees around the annular face to permit the electrical conductor 2 to be withdrawn from a fixed plate 56 having interior flat surfaces 59A and the electrical conductor 2 rotated ninety degrees and replaced within the fixed plate 56 with flats 59 of its annular face fitted to the complementary flats 59A of the fixed plate 56 to prevent rotation of the conductor 2 and, consequently, misalignment within the said fixed plate 56. Further, the test connector 1 is characterized by an electrical conductor 2 with enlarged annular waist 4 which fits within the shell 3 to prevent rotational movement relative thereto.

Precision test connector

A testing device such as a network analyzer is joined to a test unit, such as a circulator, by an electrical precision test connector 1 having an electrical conductor 2 with conductive end parts 34 and 40, a hollow, bipartite shell 3 and a dielectric insert 4 securing the conductor 2 in place, the electrical conductor 2 comprising a flexible, slotted contact end portion 34 with flat, opposing contact surfaces 36 and 37 with the slotted end portion being pinched 38 for a slideable, clamping engagement, above and below, with an inserted tab connector and the hollow, bipartite shell 3 having an end contact surface 24 and being spring biased at 45 to provide complete electrical contact with a corresponding portion of the test unit 60 during connection.

A method of terminating a malleable external shield (16) of a malleable coaxial cable (2) is carried out by inserting an end of the cable (2) into a tubular connector body (5) through one end (41) thereof and driving a shield gripping tubular metal member (8) surrounding the cable (2) into the connector body (5) from the one end (41) thereof so that the shield gripping member (8) tightly grips the cable shield (16), an external peripheral end flange (38) on the shield gripping member (8) being proximate to the one end (41) of the connector body (5). In order to afford strain relief for the electrical connection between the shield gripping member (8) and the cable shield (16), a solder ring (48) surrounding the cable (2) is held on the flange (38) and an induction heating ring (50) is employed to melt the solder ring (48) to provide a solder fillet (52) rigidly connecting the flange (38) to the cable shield (16).
