An apparatus for inserting and retention testing an electrically conductive contact in an electrical connector. The apparatus includes a connector holder, an insertion tip, an insertion tip displacement assembly, a test probe, and a test probe displacement assembly. The connector holder holds an electrical connector. The insertion tip contacts one end of a contact partially inserted in a hole in the electrical connector while providing clearance for a wire. The insertion tip displacement assembly displaces the insertion tip in a first direction along a first linear path to further insert the insertion tip in the hole in the electrical connector. The test probe contacts another end of the contact after the contact has been inserted further into the hole. The test probe displacement assembly displaces the test probe in a second direction (opposite to the first direction) along a second linear path which partially overlaps the first linear path.

An electrical male terminal of this invention includes a clamp or crimp area, a main body, and a blade. A tang member having a lever member, locks with a connector assembly. Protruding members and support members of the main body act as overstress protection. The main body includes a tapered portion, a protruding guide member, and a panel shield member to guide the electrical male terminal, the panel shield member protecting the protruding guide member. The polarity of the electrical male terminal is such that the upper portion of the main body in the upper portion of the connector assembly is narrower than the lower portion of the main body in the lower portion of the connector assembly. Also, this invention includes methods for securing a wire or cable with the electrical male terminal, using a pair of wire-insulation clamping tabs or insulation crimp wing portions, and a pair of wire-clamping tabs or core crimp wing portions.

A probe includes: a tubular barrel; a first plunger that has a proximal end portion inserted from one opening end of the barrel and slides along an axial direction of the barrel in a state in which a distal end is exposed; and a coil spring that is disposed inside the barrel and urges the first plunger in the axial direction of the barrel. The proximal end portion of the first plunger includes: an insertion portion that extends inside the coil spring from one end of the coil spring; and a head portion that is coupled to the insertion portion, has an outer diameter larger than an outer diameter of the coil spring, and abuts against the one end of the coil spring.

A method for upgrading an automatic testing system includes electrically connecting at least one pogo pin attaching device to an expansion instrument and a pogo pin of a pogo pin interface of the automatic testing system wherein the pogo pin attaching device comprises at least one metal attaching member and at least one cable having two ends electrically connected to the metal attaching member and the expansion instrument respectively, and the metal attaching member attaches to the pogo pin; and in response to operating the automatic testing system, electrically connecting the pogo pin to a subject so that a measurement path is established between the subject and the expansion instrument through the pogo pin attaching device wherein the measurement path is configured to connect signals for upgrading the automatic testing system.

A plug-in point adapter provides a self-contained adapter assembly that may be plugged into the connector jack of an existing electrical alligator clip probe and which increases the length of the probe. In some implementations, the adapter includes a test point that can be projected forward to a selectable length between the jaws of the clip that allows the clip to be used either as the point of a test probe or the original service as an alligator probe. In some implementations, the adapter transfers the alligator jack to the adapter jack for connection of the test lead plug. In some implementations, the adapter latches to the alligator clip and remains on permanently. The original alligator clip is not modified in any way and therefore the adapter can be customized for various designs of alligator clips that do not have to be modified.

A metal terminal includes a front-side terminal member and a rear-side terminal member. The front-side terminal member includes a female connection portion, and the rear-side terminal member includes a male connection portion. The female connection portion has an insertion port in which the male connection portion is inserted. The insertion port is formed in a shape that prevents the insertion port and the male connection portion from coming into contact with each other when the male connection portion is inserted therein. The female connection portion includes a terminal contact portion which brings the male connection portion and the female connection portion into contact with each other by pressing the male connection portion toward the female connection portion inside the female connection portion.
