Tooling for 2.92mm Cabled Connectors

Application Notes: 2.92mm Solder Type Straight Plugs for Semi-Rigid Cables

Accurate assembly of the 2.92mm cabled connectors is obtained with the tools listed. Industry standard devices are used if possible for customer convenience and tool compatibility. High temperature solder, such as 95/5 Sn/Ag is recommended so that contact solder joint remains stable during body soldering operation. Solder paste is recommended for the contact solder joint to minimize excess solder. The assembled dimension should be as shown. Remove excess solder from contact with a sharp blade and clean contact. Check for presence of excess solder by sliding body soldering tool over the contact. Remove soldering tool. Place connector nut and body on cable. Place connector body soldering tool over contact and thread the coupling nut and connector body firmly to the tool. Place cable subassembly into cable soldering vise. Clamp cable and soldering tool securely to insure the cable dielectric expansion will not disturb the cable in the vise during soldering. Place hot soldering iron on the connector body sleeve and apply solder from the opposite side. A low temp solder, such as 60/40 Sn/Pb is recommended for the body solder joint. Allow the soldered joint to cool and remove from fixture. Check contact location to the body. The best electrical results are achieved when the contact location is within a tolerance of 0.060 +/- 0.001. Place bead onto neck portion of the tool. Thread Bead Assembly tool firmly into the coupling nut. Push the tools plunger between your thumb and fingers to assemble the bead. Check bead location. Assemble seal ring onto body.

Application Notes: Field Replaceable

The field replaceable connectors manufactured by Johnson, are easy to install and replace. The hermetic seal is mounted into the circuit module wall and the connector can be removed and replaced without destroying the hermeticity of the circuit housing. The field replaceable connector creates a transition from microstrip circuitry to a coaxial transmission line. The 2.92mm seal pin diameter is 0.012 (0.030) to minimize the capacitive effects on the circuit trace. For optimum electrical performance, the transition from the hermetic seal to the microstrip trace must be properly compensated. Compensation involves adjusting the microstrip trace width to minimize any impedance discontinuities found in the transition area. The plot shown below is representative of the typical return loss of a Johnson field replaceable 2.92mm connector. To produce the data shown below, a test fixture is created using the Johnson 2.92mm hermetic seal. The fixture consists of a suitably thick spacer plate with the hermetic seal mounted flush to both surfaces. Two connectors are mounted back to back around the fixture and the VSWR of this test assembly is measured. The calculated return loss trace shown is equivalent to the square root of the measured VSWR of the test assembly. Since the connectors tested are of identical design, it can be stated with fair accuracy that the calculated data shown represents the response of a single field replaceable connector and its transition to the hermetic seal. Although Johnson does not publish a VSWR specification for field replaceable connectors, typical connector return loss can be expected to be less than -20 dB through 40GHz. A VSWR specification is not stated because an industry standard method for testing field replaceable connectors does not exist. The actual performance of the connector is dependent upon the following: 1. For optimum electrical performance, Johnson recommends the use of our standard 142-1000-033 hermetic seal with a pin diameter of 0.0120 (0.305) 0.0005 (0.013). 2. It is recommended that the hermetic seal be mounted flush with the circuit housing. Tolerance variations between the hermetic seal and machined housing do not always guarantee an optimum transition to the connector. Some manufacturers recommend an additional counterbore in the circuit housing to accommodate a solder washer during installation of the seal. Johnson does not recommend this type of installation because if the counterbore is not completely filled with solder, electrical discontinuities may be created. 3. The transition between the hermetic seal pin and the microstrip trace will effect electrical performance, as stated above. Several different methods of hermetic seal mounting and seal pin to microstrip trace attachment are used in the industry.

Application Notes: 2.92mm (SMK) End Launch Connectors PC Mounting Instructions (Screw-on Type)

Step A. Position the end launch connector on the pc board and make sure the connector body is fit tightly against the board edge. Step B. Insert mounting screw # 1-72 through spring washer, mounting body, pc board and bottom base. Slightly adjust the location and make sure the contact pin is centered on the signal trace. Step C. Tighten the screws and the torque force should not exceed 20 in-oz. Optional: Step D. Solder the contact pin on the signal trace by using a minimal amount of solder. Ensure the solder flows along with the length of the outside pin to create a good solder joint. Step E. Remove any excess solder and clean all flux and other residues from the solder joint area. (Note: Any excess solder or flux will affect performance.)
