A second electrical contact is provided that is substantially equal to the first electrical contact. Likewise, the second electrical contact has an annular resilient material and an annular conductor. The two electrical contacts configured to contact one another such that the annular conductors of each come into physical contact. The annular resilient materials of each electrical contact each have dielectric characteristics and dimensions that are adjusted to provide desired impedance to the electrical contacts.

A seal for a coaxial cable electrical connector more specifically an internal seal for a coaxial cable connector placed within a coaxial cable and its constituent components. A coaxial cable connector is in electrical communcation with an inductive transformer and a coaxial cable. The connector is in electrical communication with the outer housing of the inductive transformer. A generally coaxial center conductor, a portion of which could be the coil in the inductive transformer, passes through the connector, is electrically insulated from the connector, and is in electrical communication with the conductive core of the coaxial cable. The electrically insulating material also doubles as a seal to safegaurd against penetration of fluid, thus protecting against shorting out of the electrical connection. The seal is a multi-component seal, which is pre-compressed to a desired pressure rating. The coaxial cable and inductive transformer are disposed within downhole tools to transmit electrical signals between downhole tools within a drill string. The internal coaxial cable connector and its attendant seal can be used in a plurality of downhole tools, such as sections of pipe in a drill string, drill collars, heavy weight drill pipe, and jars.

A connector assembly (10) is provided including a first connector (12) and a second connector (14) configured to mateably engage the first connector (12). The first connector (12) includes a housing (16), a conductor assembly (18) positioned within the housing and projecting from housing, and a resilient seal member (30) enclosing an interface between the housing (16) and the portion of the conductor assembly projecting from the housing. The second connector (14) includes an outer contact (60), an inner contact (62) nested within a portion of the outer contact (60), and a housing (64) containing the inner and outer contacts. Conductors of the conductor assembly (18) of the first connector (12) engage the outer (60) and inner (62) contacts of the second connector (14). Another resilient seal member (45) includes a flexible skirt (50) formed at an end portion thereof. The flexible skirt (50) forms a shroud covering a mating interface between a first conductor (20) of the first connector (12) and the inner contact (62) of the second connector (14) when the first and second connectors are mated. Design features incorporated into the second connector housing (64), inner contact (62), and outer contact (60) act to retard undesirable unmating of the connectors. The connector assembly (10) of the present invention may be used in applications requiring a dual wire or coaxial connector resistant to adverse environmental conditions, such as exposure to high-pressure gases or liquids, elevated temperatures, vibration, salt spray, etc.

A connector is provided for coupling an end of a coaxial cable to a terminal. The connector includes a coupler having an annnular collar, a body member, one end of which includes a deformable lip inserted with elastic deformation through the collar opening, and a post. In a cable-installed position, the post is received in the body member to form an annular chamber sufficiently narrow in the cable-installed position to compress the outer conductor and the jacket for establishing a distal seal. Tightening of the coupler to the terminal compresses the lip between the post flange and the annular collar for establishing a proximal seal.

An electrical connector (1) includes an insulative housing (3) mounted onto a mother board, and a mulitiplicity of contact modules (7) received in the housing. The housing defines first and second openings (245, 246) in a front portion thereof. Each contact module includes first, second, third and fourth contacts (80, 82, 86, 88) and a ground contact (84). The first and second contacts are inserted into the first opening to form a first signal contact group, thereby providing a first mating interface for a daugher board. The third and fourth contacts are inserted into the second opening to form a second signal contact group, thereby providing a second mating interface for another daughter board. The ground contacts are disposed betweent the first and second signal contact groups. The connector can thereby electrically connect the daughter boards with the mother board simultaneously.

An electrical connector assembly for a cable having a plurality of insulated conductors comprises a body having a respective recess for receiving a terminating pin each of the conductors. A respective spigot sealingly engages within each of the recesses and has a passage for receiving an associated one of the terminating pins. Furthermore a seal is associated with each of the spigots for sealing the spigot relative to the associated terminating pin. The provision of a separate spigot for each of the conductors and for sealing engagement within a respective recess in the body enables the spigots to be sealingly fitted to the conductors prior to each spigot being introduced into its recess and sealingly engaged therein. This provides improved insulation of the conductor and increased creepage distance between the mating electrical parts and the outer surface of the housing of the assembly. It also provides the additional advantage that the seal on the conductor tends to be smaller than in prior arrangements so that there is less thermal expansion of the seal when the parts get hot in a downhole environment.

An electrical connector is provided that includes a housing holding a plurality of contact modules. Each contact module contains a contact lead frame that includes signal leads and ground leads arranged in one of a first and second patterns. The first and second patterns each include pairs of signal leads and individual ground leads arranged in an alternating sequence. Each pair of signal leads is coupled to a ground lead in an adjacent contact module and the coupled ground lead in the adjacent contact module is substantially spacially centered between the pair of signal leads.

A contact module includes a plurality of conductive contacts and an insulator retaining the contacts. Each of the contacts includes a contact portion at one end thereof, a terminal portion at the other end thereof, and an intermediate portion extending between the contact portion and the terminal portion. The intermediate portion has a positioning-subject portion. The insulator includes grooves each receiving therein the intermediate portion of the corresponding contact, positioning portions each positioning the positioning-subject portion of the corresponding contact, and retaining portions each retaining the intermediate portion of the corresponding contact. The positioning-subject portions of the contacts are press-fitted into the positioning portions of the insulator so that the contacts are provisionally retained by the insulator. By the use of the retaining portions, the contacts are finally retained by the insulator.

An integrated seal assembly and a coaxial cable system component incorporating the seal assembly with a connector for coupling to an externally threaded port. The seal assembly includes a bellows-type seal having an elastically deformable tubular body and a plurality of sealing surfaces, and an integral joint-section intermediate an anterior end and a posterior end that assists in the axial deformation of the seal in response to axially-directed force. One of the sealing surfaces is made to engage a corresponding surface of an internally threaded nut or housing. The component is engagable with an externally threaded port via the internally threaded connector. The anterior end of the seal fits over the port and a sealing surface of the seal is capable of sealing axially against a shoulder of the port while the seal body covers the otherwise exposed externally threaded port. Upon tightening of the nut on the port, the seal deflects in the axial direction to accommodate a variety of distances between the connector and the shoulder of the port. Additionally, the seal is capable of expanding to allow a second sealing surface to contact and seal against a variety of smooth outside diameters of the port. The versatility of the seal allows an operator to use one connector of a system component on a wide variety of externally threaded ports without the risk of a faulty seal at the connection or a poor connection due to an improper seal.

A power connector includes a housing (10) defining a tube-like receiving chamber (16) extending through a front face (11) thereof and a receiving hole extending through a rear face (12) thereof, a first contact (20) extending into the receiving chamber, and a second contact (50) extending into the receiving hole. The receiving hole comprises a front section (17) and a rear section (18). The front section is communicating with the receiving chamber and is larger than the rear section in diameter thereof to form a step portion therebetween. The second contact (50) is a single piece and comprises an engaging portion (51) extending in the receiving chamber, a retaining portion (52) extending from the engaging portion and engaging with the step portion for preventing the second contact from moving rearwardly, and a connecting portion (53) extending from the retaining portion and comprising a bent portion engaging with the rear face of the housing for preventing the second contact from moving forwards.
