Abstract:
A cable assembly apparatus for coupling a connector to a cable having a base supporting an interface pedestal dimensioned to receive the connector; an inductor coil coupled to an inductor coil actuator operable to move the inductor coil between a load position and an operation position proximate the interface pedestal; a grip clamp operable by a clamp actuator to move between an open position and a closed position above the interface pedestal; and a temperature sensor configured to read a temperature proximate the interface pedestal. A method for using the apparatus retains the preassembled connector and cable in an aligned orientation for controlled heating by the induction heater to heat a solder preform to solder the connector to an outer conductor of the cable.
Abstract:
A solder-on connector (6) for a coaxial cable (8) includes a body (12) having a bore (19) for receiving the outer conductor (30) of the cable, a center pin (20) for connection with the center conductor (30) of the cable, an insulator (22) disposed within the bore of the body for supporting the center pin, and a nut (14) or similar fastener for securing the connector to a mating connector. The insulator extends rearwardly within the body to abut the both the inner wall of the body and the inserted end of the outer conductor (26) of the cable. The rearmost portion (34) of the insulator serves as a solder dam to prevent excess solder (27) form flowing into the bore of the body beyond the end of the outer conductor of the cable. The rearmost end (13) of the body includes an enlarged diameter region (48) for receiving a portion of the cable jacket (24). An inwardly-directed annular shoulder (54) formed upon such enlarged diameter region captivated melted portions (52) of the cable jacket when the outer conductor is soldered to the body.
Abstract:
A soldering material (28) is joined to a surface (13a) of a terminal (13). The terminal (13) is incorporated in a groove (18) of a connector housing (11) so that a covered wire (19) is made into contact with the terminal (13). A cover (12) is mounted so as to insert protrusions (22) into the grooves (18). By carrying out ultrasonic vibration while applying a pressure by a ultrasonic horn, a covering portion of the covered wire is melted and removed. The soldering material (28) is melted by heat generated when the covering portion is melted so that the soldering material (28) is made into contact with the cores thereby the cores and terminal (13) being connected with each other through the soldering material (28). As a result, the soldering material (28) makes a firm contact with the cores.
Abstract:
A lead frame (1) for an electroacoustic transducer, forming leads of the electroacoustic transducer, comprising a metal sheet (2) made of a metal having elongation 20% or higher, a nickel undercoat deposit (3) of a thickness in the range from 0.01 to 2.0 µm formed on the metal sheet (2) by plating in a nickel plating bath containing no brightening agent, and a solder deposit (4) of a thickness in the range from 1.0 to 10 µm formed on the surface of the nickel undercoat deposit (3) by plating in a tin-lead plating bath containing no brightening agent. With the lead frame (1) formed by plating the metal sheet (2) as stated above, micro-cracking occurring in the bent corners of the metal sheet (2) and the solder deposit (4), when the outer leads of the lead frame (1) are bent at an angle of 90°, can be prevented.
Abstract:
A retention sleeve (150) is placed over the rearward end (134) of the outer conductive shell (120) of a coaxial plug connector (100), providing a rearward stop for retaining the coupling nut (12) on the shell. The retention sleeve can include an inwardly directed flange (158) at its rearward end for retention of an annular solder preform (132) within the cable-receiving bore (136) of the outer conductive shell. The retention sleeve (150) can be of low resistance copper having a thin outer layer (170) of magnetic high resistance metal, defining a self-regulating temperature source when subjected to RF current, to reflow the solder of the preform (132) and thus solder the outer conductive shell (120) to the semirigid outer conductor (82) of the coaxial cable end inserted into the cable-receiving bore (136) providing for automated soldering.
Abstract:
Un procédé et une borne utilisés pour relier à la masse des conducteurs avec une grande fiabilité combine des techniques de percement d'isolation et de brasure. Des bornes (10, 34, 52, 81, 104) sont formées avec des parties (12, 38, 40, 66, 68, 88, 90, 104) de percement d'isolation et d'appui des conducteurs ayant une couche de brasure (32, 50, 84) intégralement formée sur elles. Des bornes terminales sont appliquées sur des conducteurs respectifs (22, 36, 74, 106) par une opération de percement d'isolation et la brasure est refondue pour former un lien permanent entre les conducteurs et les bornes. La fente (18, 46, 48, 70, 72, 80) de la borne nettoie la surface du conducteur et la retient pendant l'opération de refonte de la brasure.

A wiring harness assembly (100) includes a plurality of separated conductors formed of an electrically conductive material, a substrate (104) formed of a dielectric material encasing the plurality of separated conductors, a location feature (108) integrally formed with the substrate (104) and an opening defined in the substrate (104) having a predetermined size and shape. A section of the plurality of separated conductors is exposed within the opening. The opening is precisely located relative to the location feature (108).
Abstract:
The invention relates to a method for carrying out solder connections in a technologically optimized manner, in particular lead-free solder connections. At least one of the joining partners provides the solder required for the connection. A flux is used in order to activate the solder, and the electric and mechanical connection is carried out by means of a soldering process under the effect of heat and by melting the solder/flux mixture with the inclusion of a subsequent cooling phase. According to the invention, the joining partners and the solder are heated to a temperature below the activation temperature of the solder and the flux in a first temperature treatment phase. Another heating process is then carried out to a temperature above the activation temperature of the flux up to the upper melting range of the solder in a second temperature treatment phase, wherein the solder melts and begins to connect to the respective joining partners. Furthermore, the thermal output previously applied is increased by an additional 5% to 30% in a third temperature treatment phase in order to accelerate the adhesion behavior of the joining partners.
