Abstract: A connector in which an electrical contact portion of a female terminal has a tubular portion corresponding in shape to a terminal receiving chamber in a connector housing. A slit is formed in the tubular portion, and extends in a direction of insertion of the terminal. An engagement projection which is slidably fitted in the slit is formed on an inner surface of the terminal receiving chamber. When the female terminal is inserted in a proper manner, the engagement projection is fitted into the slit in the tubular portion, and therefore the female terminal is completely inserted into the terminal receiving chamber. On the other hand, when the female terminal is inserted in a wrong manner, the front end of the tubular portion abuts against the engagement projection, thereby preventing the insertion of the female terminal.

Abstract: A set of battery jumper cables includes a pair of single pole, single throw switches, or equivalent semiconductor implement switches. The switches are connected in series between the battery connection terminals of each cable in the set to prevent arcing. Control wires and a delay circuit connect the two terminals at one end of the set to the operating coil of one of the single pole switches. Similarly, another set of control wires and a delay circuit connect the terminals at the other end of the set to the operating coil of the other switch. In operation, these two switches in their unenergized state are open and automatically current flow through the cable set until after all four cable terminals are connected respectively to battery terminals and the relay delay has timed out, thus preventing arcing as the terminals are connected and disconnected or if the terminals at one end are shorted to each other.

Abstract: A coaxial connector with a switch has a central terminal, an outer terminal, and a switch terminal. When a plug is inserted in the coaxial connector, the central terminal is connected to the plug central terminal of the plug, while the outer terminal is connected with the plug outer terminal. At this time, the switch terminal comes into contact with the plug outer terminal, and it is electrically connected to the outer terminal via the plug outer terminal.

Abstract: A safety jumper cable has two cable segments each with conventional terminal clamps on one end and a coupling on the other end. The terminal clamps are adapted to be secured to the battery terminals in the conventional manner. The cable couplings cannot physically be connected together by means of a positive fail-safe lockout unless the clamps are secured to the proper battery terminals. This lockout is provided by a normally extended, locked safety blade that is slidably mounted within each coupling. When the terminal clamps are attached to the proper battery terminals, the safety blades are unlocked and the safety jumper cable can be coupled together away from either battery and the danger of sparking and explosions. The safety jumper cable may also be provided with a manual override device.

Abstract: A method of making a solder connection. An element bearing a solder mass is forcibly engaged with another element bearing a resilient metallic contact so that the contact wipes the surface of the solder mass and so that the contact is deformed and bears against the wiped surface. While the contact is in its deformed condition, the contact and solder mass are brought to an elevated bonding temperature sufficient to soften the solder, so that the contact penetrates into the solder mass under the influence of its own resilience. The contact bonds with the pure solder inside the solder mass, so that the effective bonding can be achieved even without flux.
