Abstract: A method and a device is provided which allows the connection of coaxial cable termini to one another with minimum long-term loss of RFI shielding. The method comprises the removal of metal oxides from the concentric conductor portions of the two cable termini, applying a sealant to the concentric conductor termini and then connecting the central conductor termini to one another and the concentric conductor termini to one another. The device comprises a collet structure dimensioned to slip over the outside of a standard connection jack. Within the collet structure is disposed a quantity of sealant and the collet structure has at least one aperture through which sealant oozes from the collet structure to the exterior of the collet structure. When the collet structure is attached to the jack, the sealant is caused to ooze onto the concentric conductor thereby sealing the concentric conductor from the ambient.
Abstract: The connector pin (2) is protected by a lid (6) which is opened into the sleeve portion (3) when the plug portion (1) is slid in linearly. For this purpose, a sleeve portion is provided with a control path, for example in the form of guide grooves (30), which coordinates with the cover (6). When withdrawing the plug portion (1), the lid (6) is once again closed with the aid of the control path.

Additionally, projecting parts (26) which contact the rear ends (18b) prevent more than a specified amount of deformation of the elastic contact members (18). The projecting parts (26) are provided at a specified distance to the rear of the positions of the rear ends (18b) of the elastic contact members (18).
Abstract: Disclosed is an improvement in an electric connector for connecting two spaced apart parallel printed circuit boards having a plurality of needle-like pin terminals arranged laterally at regular intervals between its upper and lower wafers, the upper and lower extensions of the needle-like pin terminals extend beyond the upper and lower wafers being connected to selected conductors on upper and lower printed circuit boards. According to the present invention the needle-like pin terminals freely pass through the longitudinal pin-receiving openings made in the upper and lower wafers, and metal tie rods are press-fit in opposite longitudinal rod-insertion apertures made at the opposite ends of the upper and lower wafers, and are detachably fixed thereto, thereby constituting a rigid integrity.
Abstract: A universal cable connector includes a plurality of different sized connectors adapted to mate with the proximal connectors of different sized implantable leads. The cable connector attaches to a system analyzer and enables the system analyzer to interface with whatever implantable leads are connected to the connector block, thereby allowing the system analyzer to perform desired tests, such as threshold-determining tests, using the implanted leads. An adapter cable and clamp is also provided that allows an electrical connection of the proper polarity to be established between an implantable cardioverter-defibrillator (ICD) and the cable connector block while the ICD is connected to a patient and is operating, thereby permitting the system analyzer to monitor the performance of the ICD.
Abstract: An electrical connector for use in electrically conductive aqueous mixtures, solution or suspensions such as seawater, sewage, electrolytes and so forth has one or more contact pins 3 each having a contact area 4. The contact areas 4 are electrically isolated from the electrically conductive environment by way of a dielectric seal carrier 6 which may be moved away from the contact areas 4 as the socket and the plug of the connector are brought into engagement.
Abstract: A watthour meter socket adapter has a spring loaded jaw-type electrical receptacle adapted to receive a blade-like contact of a watthour meter. The electrical receptacle has a main blade member or bus bar with a terminal end portion thereof forming a first jaw at the end of the receptacle. A jaw member overlies and is rigidly secured to the main blade member, with a terminal end portion thereof forming a second jaw at the end of the receptacle. The overlying main blade member and jaw member having cooperating relatively straight contact faces that face one another on opposite sides of a narrow insertion space for receiving said blade-like contact. A narrow transverse slotted opening extends across a lower portion of the insertion space between the main blade member and the overlying jaw member. A spring member normally applies a spring biasing force to urge the contact faces toward one another for closing the space between them.
Abstract: An interface selection and configuration system for a computer peripheral in which configuration for the peripheral is at least in part accomplished by the interface connector cable. In a preferred embodiment, the computer peripheral is equipped with one or more hardware interfaces. The interface connector cable has a first end connector for attaching to the computer peripheral. The first end connector of the interface connector cable is typically a multiple pin connector constructed and arranged to be properly physically and electrically connectable only to a specific computer peripheral or class of computer peripherals, the first end connector including at least one electrical connection between two pins for completing a circuit within the computer peripheral thereby enabling the computer peripheral.

Abstract: Connector, comprising a body of electrically insulating material, contact members fitted in the body, and an outer conductor fitted around the body, the body being provided at a contact side with one or more contact holes for receiving signal pins of a complementary connector and contacting them with the contact members, the outer conductor being provided with one or more strip-type contact springs extending along the connector, for contacting earth pins of the complementary connector, the contact springs being made integral with the outer conductor, an edge of the outer conductor lying at least in the vicinity of the contact side of the body, and the contact springs extending essentially from the said edge along the outer conductor, in such a way that the outer conductor has an essentially uninterrupted outer periphery.
Abstract: A projection-type male connector component includes a buttress of insulative polymeric material surrounded by a number of electrically conductive contacts electrically isolated from each other. The male component is designed to mate with an equal number of female cantilever beam contacts. The buttress is provided with a tapered end and the male contacts are bent over this tapered end so that the female contacts touch the male contacts when the male and female contacts are mated rather than the insulative material from which the buttress is made. In this way, excessive wear of the female contacts is avoided.
