Connection Method for Pressure Welding Type MIL Socket Connector
The MIL standard socket connector is a small and highly versatile connector used for connecting various input/output signals, such as solenoid valves and programmable controllers in FA and SCSI and IDE in computers. The pressure welding type, which can connect cables easily, is especially popular and used widely. Although it is desirable to use dedicated tools specified by the manufacturer in terms of reliability of cable connection for the pressure welding type, most dedicated tools specified by the manufacturer usually cost about fifty to one hundred thousand yen. This kind of expense is out of the question when manufacturing a small prototype. Here we introduce a method for simple pressure welding, which can be useful when manufacturing prototypes or simple jigs. However, after processing, please thoroughly check the finish and connection before use.
(1) First of all, select the cable. Flat cables (photo 1) with wire spacing of 1.27 mm pitch can be used. Types of flat cables include the bridge type, which is nearly all gray wires except for red and green, the intermittent bonded gray type, in which the flat portion turns to loose wires partway through, and the twisted-pair flat type which is intermittent bonded and resistant to wire twisting noise; there are also flat cables with shields and color types using a variety of colors.
(2) Once you have selected the cable, cut it straight with scissors. (Picture 2) If it is cut curved or diagonally, the conductor may not reach the blade of the contact. Then apply the cut cable to the uneven portion of the holding plate. (Picture 3)
(3) Next, considering the cable draw-out direction, position the ▼ mark of the connector so that it matches the first wire (if it is gray type match with the red line, if it is color type match with the brown line) and apply the edge portion of the connector to the cable. Press down firmly with a finger so that the cable is not aslant. (Picture 4)
(4) After that you only need to clamp and weld with a vise or simple pressure welding tool. (Picture 5) However, please perform the welding gradually and slowly. Also, if there is a lock lever as in the relay connector and the tool cannot be applied to the operation side, please use a wood block etc. so that there is always uniform force applied to the whole connector. Note that relay connector welding cannot be performed with a simple pressure welding tool.
(5) When the welding is complete, pull the connector out from the tool. (Picture 6) The strain relief is installed from the back of the connector so that the contact portion does not disconnect if force is applied to the cable during use. (Picture 7) Finally, check the conduction and the finished appearance of the pressure welding. (Picture 8)
