Abstract:
Conductive fine particles having an ability of relaxing the force exerted on a circuit of, e.g., a substrate and a method for retaining the constant distance between substrates are disclosed. The conductive fine particles are composed of basic fine particles of resin each covered with one or more metallic layers. The coefficient of linear expansion of the resin is 3 X 10 to 7 X 10 (1/K).
Abstract:
Removing the electrical field from the internal volume of high-voltage structures, e.g., bushings, connectors, capacitors, and cables. The electrical field is removed from inherently weak regions of the interconnect, such as between the center conductor and the solid dielectric, and places it in the primary insulation. This is accomplished by providing a conductive surface on the inside surface of the principal solid dielectric insulator surrounding the center conductor and connects the center conductor to this conductive surface. The advantage of removing the electric fields from the weaker dielectric region to a stronger area improves reliability, increases component life and operating levels, reduces noise and losses, and allows for a smaller compact design. This electric field control approach is currently possible on many existing products at a modest cost. Several techniques are available to provide the level of electric field control needed. Choosing the optimum technique depends on material, size, and surface accessibility. The simplest deposition method uses a standard electroless plating technique, but other metallization techniques include vapor and energetic deposition, plasma spraying, conductive painting, and other controlled coating methods.
Abstract:
The invention relates to an electrical distributor (1) which can be mounted on a pre-fabricated wall (45), comprising connections (3) on one side (5) of the distributor (1) and other connections (9) on the other side of the distributor (1). Each contact (3) is electrically connected to at least one other contact (9) on the other side (7). Both sides (7, 5) are mounted in relation to each other in such a way that they are arranged on both sides of the distributor after assembly. According to the invention, the distributor can be fixed to a pre-fabricated wall in a relatively simple and therefore economical manner if each contact is connected to one other contact, if at least one common conductor (35) is physically placed between both sides (5, 7) of the distributor (1), if said conductor is located between the pre-fabricated wall and the other side (7) once the distributor has been mounted on the pre-fabricated wall, if the additional connections (10) are connected to at least one common conductor (35) and if said connections are arranged near to a further connection (9) on the other side of the distributor (1), forming a pair of connections (13) therewith, and if the connections (9, 10) of said pair of connections (13) form contact elements for outlets (15) respectively accommodating at least one bipolar plug (25).
Abstract:
A clasp (20) for a biomedical electrode (12) includes opposed cooperating jaw members (23, 24). The jaw members (23, 24) can be end portions of a U-shaped leaf spring (30). A lever (40) is pivotally mounted for engagement with the jaws (23, 24) for forcing the jaws together to grip an electrode (12) placed between them. An opening (26h) is provided within the clasp (20) for receiving the stud (17a) of a different style electrode and a retaining tab or finger (30t) is provided for engagement with the stud (17a) to shift the stud to a locked position in the opening (26h) when the lever (40) is pivoted toward its operative or closing position.
Abstract:
The invention relates to a method for producing at least one spring contact pin (9) acting as an electrical contact, or a spring contact pin arrangement (25) comprising at least one such spring contact pin (9). The following steps are provided: - producing at least one base part (8) of the spring contact pin (9), at least one section of said base part (8) being made of plastic, and - subsequently metallising at least the section of the base part (8) that is made of plastic.
Abstract:
A leadframe module for an electrical connector includes a leadframe having contacts initially held together as part of the leadframe. The contacts have mating ends configured to be mated to corresponding mating contacts. The contacts having mounting ends configured to be terminated to corresponding conductors. Dielectric shells coat corresponding contacts. Outer shields are applied to corresponding dielectric shells. Each of the contacts, dielectric shells and outer shields define corresponding shielded transmission lines of the leadframe module. Optionally, a ground plate may be coupled to each of the transmission lines and electrically connected to the outer shields of the transmission lines to electrically common each of the outer shields.
Abstract:
A multi-part multiple pole coaxial electrical connector (10) comprising two interengageable bodies (11a, 11b) of electrically insulating material each provided in a zone of engagement thereof with the other body with a coating of electrically conductive material. A first one (11a) of the bodies is formed in its zone of engagement with a sequence of three radially spaced-apart concentric electrically conductive plugs (13a, 13b, 13c) electrically insulated from one another at insertion ends thereof. The second one (11b) of the bodies is formed in its zone of engagement with a sequence of three radially spaced- apart concentric electrically conductive sockets (15a, 15b, 15c) electrically insulated from one another at entrance ends thereof. The centre plug (13a) is engageable with the wall of the centre socket (15a) to provide an electrical connection therewith forming a centre pole and each radially outer plug (13b, 13c) is engageable with and only with a radially outer wall of the corresponding radially outer socket (15b, 15c) to provide an electrical connection therewith forming a respective radially outer pole separated from the or each adjacent pole by an air gap (16).
