A connector assembly includes a plug connector assembly and a receptacle connector assembly matched with each other. The plug connector assembly includes a metal shell and a plug connector. The plug connector includes a number of plug terminal modules. Each plug terminal module includes a first differential signal terminal, a first ground terminal, and a second ground terminal. The receptacle connector assembly includes a metal cage and a receptacle connector. The receptacle connector includes a number of receptacle terminal modules. Each receptacle terminal module includes a second differential signal terminal, a metal shield surrounding member surrounding a periphery of the second differential signal terminal, and a receptacle cable electrically connected to the second differential signal terminal.

An improved perforating gun with novel endplates is disclosed along with a corresponding method of assembly. The endplate may include a base with first end separated from a second end separated by a curved sidewall centered around a longitudinal axis and a set of tube tabs flexibly coupled to the base and extending from the second end. The endplate may include a carrier tab with an integrated alignment pin. Selected embodiments may also include a zero-tension connector with a sliding contact mounted within a cavity of a housing, a through-wire connected to the sliding contact. The novel endplate reduces the cost and complexity of manufacture and installation.

An electrical feed-through includes: a feed-through component having an opening; at least one conductor sealed into the opening of the feed-through component in a glass material or a glass ceramic material; and at least one guide component connected to the feed-through component, the at least one guide component including a material that is a plastic.

An electrical connector comprises a housing having a water stop groove and a region disposed between an end of the housing and the water stop groove. The water stop groove extends along a circumferential direction of the housing orthogonal to a mating direction of the electrical connector. The water stop groove is dimensioned to allow a surface tension to act on a quantity of water accumulated in the region.

Provided is a connector in which first and second connector members are fitted with each other. The first connector member includes a first housing formed with a protrusion. The second connector member includes a second housing; hood member; elastic member; and locking mechanism. The hood member is to cover and to be mounted with the second housing. The elastic member is to be provided between the hood member and second housing. The locking mechanism is to lock the protrusion. The locking mechanism is operated so that the protrusion is drawn in a fitting direction. After the movement of the first and second connector members in the fitting direction is restrained, the locking mechanism is operated so that the hood member is moved while compressing the elastic member, which fix the locking mechanism with the elastic member being compressed.

A pressure-blocking feedthru that is exposable to varying temperatures and pressures includes various components. For example, the pressure-blocking feedthru might include pressure-blocking assemblies that each include a respective pressure-barrier shell and insulated pin assembly. The pressure-blocking feedthru also includes an interface assembly that couples the pressure-blocking assemblies to one another. The interface assembly includes a double-ended socket for coupling the insulated pin assemblies and a sleeve that circumscribes the doubled ended socket and at least part of the first and the second ceramic pin assemblies. In addition, the pressure-blocking assemblies might each be connected to a cable-connection assembly that employs a pressure-balanced cable termination.
