One of the first and second connectors is provided with shutters each of which is pivotally moved outwardly upon application of an external force to a front surface portion of the respective shutters.

Abstract: An automotive battery connection assembly comprises terminals for automated connection to battery posts, and a housing with plus and minus pole circuitry mounted therein. The terminal comprises a contact section and a rotatable spring element that has tabs that cam against the periphery of the contact section. Rotation of the spring element thus clamps the battery post between the spring element and the contact section. The latter design enables robotic assembly of the battery terminals to battery posts, for example by means of a tool having pins that engage in slots of the spring element. Within the housing, a linear actuation motor drives a bridge element between tabs of the plus and minus pole circuits respectively for short circuiting the battery in the occurrence of an accident. The short circuiting blows the high current fuse thereby disconnecting power supply to most devices of the automobile. The latter is to prevent occurrence of electrical fires.

Abstract: A female terminal includes a resilient contact piece portion which has a front folded portion folded back from a front end of a flat bottom plate portion of a tubular contact portion, an ascending piece portion extending slantingly upwardly from the front folded portion toward a top plate portion of the tubular contact portion, and a descending piece portion extending slantingly downwardly from a distal end of the ascending piece portion toward the bottom plate portion. A free end portion of the descending piece portion is arcuately bent, and is directed toward the front folded portion to form a resilient abutment portion. With this construction, the contact pressure is obtained not only by the reaction forces from the ascending piece portion and the descending piece portion, but also by the reaction force from the resilient abutment portion, and therefore the large contact pressure can be obtained even with the small configuration.

In addition, each wafer includes windows through which selected contact elements can be cut to either improve the performance of the shields or to allow attachment of resistors.

Abstract: An insulating member has two (2) spring arms each normally biased to a first position and each pivotable to a second position. A pin in a housing at one end of the spring arms provides the spring arm pivot fulcrum. Resilient electrical conductors extend through apertures in the other ends of the spring arms. Looped portions in the conductors at positions beyond the apertures resiliently engage, respectively, probes and shield casings in a pair of electrical connectors when the spring arms are biased to the first positions. Additional looped portions in the conductors at positions between the apertures may be fixedly positioned relative to the housing by an insulating pin extending into the housing to the approximate center of such additional looped portions. The probes and shield casings are included in coaxial connectors disposed within the housing. The connectors include insulators between the probes and the shield casings. The connectors are coaxial with a pair of barrels disposed within the housing.

Abstract: An electrical connector is adapted for mounting on a printed circuit board. The connector includes a dielectric housing having a mating face and a board-mounting face. At least one mounting post projects from the board-mounting face for insertion into a mounting hole in the printed circuit board. The mounting post is bifurcated lengthwise thereof and includes a relatively rigid leg of a substantially C-shaped cross section defining a slot extending longitudinally thereof. A relatively flexible leg includes a latch for latching engagement with the printed circuit board at the mounting hole. The flexible leg is sized for flexing movement substantially into the slot in the C-shaped rigid leg. Therefore, the C-shaped rigid leg provides an overstress protection for the flexible leg.
