The elastic contact part (30) has: [a] a spring arm (33) that has an embossment (34) with a substantially spherical surface that presses against the conductive member (60); and [b] a substantially circular hole (38) that faces the embossment (34) of the spring arm (33), and that has a rim that is contacted in a substantially circumferential state of contact by the conductive part (62) of the conductive member (60) pressed by the embossment (34).

Abstract: A connector can easily and reliably be checked to see whether the requisite minimum quantity of sealing compound has been injected. Tabs 14 of male terminal fittings 13 protrude from a base face of a fitting space 12. A sealing compound 20, consisting of epoxy resin or the like, is injected at the base portion of these tabs 14. A first step 15 and a second step 30 protrude into the space 12, the first step 15 being above the second step 30. After the sealing compound 20 is injected, the quantity injected is checked by observing the space 12 visually from above. If only the first step 15 is visible, the correct quantity of sealing compound 20 has been injected, if both the first step 15 and the second step 30 are visible, a quantity of the sealing compound 20 less than the minimum quantity has been injected.

Abstract: A two component connection system consisting of a female connector and a male connector. The female connector consists of three components joined together with a bolt. First is a cup that has the same inner and outer diameters as the tubing that forms the rest of the inner conductor. Second is a bushing stepped diametrically in three places. The first step accepts a standard anchor insulator. The second step is the same diameter as the outside of the inner conductor tubing. The third step has a diameter that allows it to fit snugly inside of the inner conductor tubing. The male connector consists of a cylinder with a bushing on one end that allows it to be assembled to inner conductor tubing and a diameter on the other end with a tandem pair of glands for watchband style springs that fits inside of the female connector cup. The cup of the female connector is fixed in position relative to the outer conductor by the captured anchor insulator.

Abstract: A female electrical connector (164') is carried on an electrical cable (24') including plural electrical conductors (28'). The female connector includes an insulative housing (34a', 34b') defining a blind cavity (36') therewithin and an axial opening outwardly from the cavity. The housing carries a printed circuit board (166) carrying plural wire-like contacts (40') which individually connect with the conductors of the electrical cable. The wire-like contacts extend into the cavity of the connector for deflecting in spring-like contact with electrical contacts (60) carried by a male connector (20) when the latter is inserted into the cavity of the female connector. A comb feature (50') of the female connector is formed by a strong end wall (138') of the blind cavity and in a respective one of plural slots (48') of the comb feature movably receives a free end portion (46') of each one of the plural wire-like contacts.

Abstract: A lead sealing device that resides within the connector cavity of a pacemaker or defibrillator intended to prevent fluid intrusion by automatically sealing the lead lumen when the lead connector is inserted. The sealing mechanism may be in the form of a silicone disk located at the base of the space defined by the connector cavity in which the lead is inserted to make electrical and physical contact. It may be fixedly located at the bottom of the connector cavity, or may be a movable plug located within the connector cavity at a location other than the bottom of the cavity, such as adjacent to the connector block. In that case, the pin will make contact with the movable plug immediately after passing through the connector block, and will remain in contact with and seal the lead lumen while the pin and plug are further advanced to bring the pin into its final location to make electrical contact with the connector contact.
