A connecting structure for a drill collar of a logging while drilling instrument and drill collar sub male and female joints are provided. The connecting structure for a drill collar of a logging while drilling instrument includes a male connecting joint and a female connecting joint matched with each other. The male connecting joint and the female connecting joint are rotatable relative to each other. Electrical passages are respectively arranged in the male and female connecting joints. One of the male and female connecting joints is provided with a multi-core coaxial electrical male connector connected with the electrical passage, and the other is correspondingly provided with a multi-core coaxial electrical female connector connected with the electrical passage. The male connecting joint is coaxially nested in the female connecting joint. The multi-core coaxial electrical male connector is inserted into and fitted to the multi-core coaxial electrical female connector.

The present disclosure provides embodiments of direct current (DC) power connectors and methods to manufacture the same. More specifically, the present disclosure provides a connector plug with improved power capacity and structural rigidity. The connector plug includes an inner body and an outer body coupled to transmit power through the DC power connector, wherein the inner body is concentrically arranged within the outer body, and an insulating barrel that is coupled between the inner body and the outer body to electrically isolate the inner body from the outer body. The inner body and outer body comprise a base metal or metal alloy having an electrical conductivity ranging between 30% International Annealed Copper Standard (IACS) and greater than or equal to 99% IACS. In addition, the inner body, outer body and insulating barrel comprise an inter-locking feature, which increases the structural rigidity of the connector plug and prevents disassembly when the inner body, outer body and insulated barrel are assembled together.

Various techniques are provided for displacing air from partial discharge sensitive regions of a connector of a low partial discharge high voltage connector to other regions of the low partial discharge high voltage connector where electrical flux is reduced. A plug member is mated with a receptacle member to provide the connector, with a seal member disposed in a cavity provided by the plug member and/or the receptacle member. In response to the mating, the seal member is compressed at an initial contact region between an innermost layer and an outermost layer of the seal member. In response to the compressing, air is forced radially inward toward the innermost layer and radially outward toward the outermost layer away from the initial contact region to reduce partial discharge associated with the connector. Additional methods and systems are also provided.

An improved perforating gun with novel endplates is disclosed along with a corresponding method of assembly. The endplate includes a base with a 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. Each of the set of tube tabs has a retaining lip and is generally oriented in a direction of the longitudinal axis. The endplate may include an optional 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.

A contact arrangement for a coaxial plug comprises an inner conductor contact having an insertion opening for inserting a mating contact in a mating direction, and an insulating dielectric body enclosing the inner conductor contact. The inner contact and the insulation body each define insertion bevels in an area of the insertion opening.
