A pass-through connector for a battery pack having a hermetic casing is disclosed. The pass-through connector has a body including: a hermetic electrical, a first body portion defining a first connector portion, a second body portion opposite the first body portion, and a flange connected to and projecting radially from the second body portion. The pass-through connector also has a second connector portion selectively connected to the first connector portion, and a gasket abutting an engagement surface of the flange and adapted for providing a hermetic seal between the pass-through connector and the casing. At least one of the first body portion and the second connector portion defines at least one recess for permitting gas exchange in and out of the casing. A battery pack having the pass-through connector, and a method for introducing at least one gas in a hermetically sealable casing for a battery pack are also disclosed.

A connector includes a wire harness, and a connector main body to which the wire harness is attached. The connector main body includes a first substrate stack in which a plurality of first substrates are held in a vertically stacked state, a first bottom substrate that forms the lowermost first substrate of the first substrate stack and includes a coupling post extending upward from an upper face, and a second substrate stack that is arranged on a lateral side of the first substrate stack and in which a plurality of second substrates are held in a vertically stacked state. At least one of the plurality of second substrates included in the second substrate stack is provided with a coupling hole (a through hole provided in the second substrates of the second layer, the fourth layer, and the sixth layer) that can be fitted to the coupling post (a right post).

A board mounting type connector includes a housing, a plurality of contact portions to be extending from the housing toward a circuit board, and a plurality of protrusions to be protruding from the housing toward the circuit board. The plurality of contact portions are aligned along a width direction at a first position in a fitting direction. The connector and a mating connector are to be fit each other in the fitting direction. The width direction intersects the fitting direction. The plurality of protrusions are aligned along the width direction at a second position in the fitting direction. A distance between the first position and a position of a center of gravity of the connector in the fitting direction is longer than a distance between the second position and the position of the center of gravity in the fitting direction.

A bracket includes an upper bracket and a lower bracket. The upper bracket and the lower bracket support a supported body from above and below between the upper bracket and the lower bracket. The lower bracket has a pair of lateral lower bracket sidewall portions overlapping with a pair of lateral upper bracket sidewall portions of the upper bracket. The lateral lower bracket sidewall portions catch with the lateral upper bracket sidewall portions to catch the lower bracket on the upper bracket.

A circuit board includes a first locking mechanism configured to secure the circuit board to a chassis. The circuit board also includes a connector disposed at an inboard end of the circuit board. The connector is configured to be electrically connected to a mating connector on either a backplane or a circuit board. The circuit board also includes a second locking mechanism. The second locking mechanism is configured to secure the connector of the circuit board to the mating connector of the backplane or the circuit card.

A connector assembly includes a connector module having a connector body with side edges and end edges. The connector body has contact channels holding contacts. The connector assembly includes a mounting frame having side walls and an end wall opposite a window between the side walls. The window is open to and provides access to a passage that receives the connector module. The mounting frame includes a connector module support structure for supporting the connector module in the passage that defines a confined space oversized relative to the connector body of the connector module to allow a limited amount of floating movement in the confined space in a lateral direction that is perpendicular to the mating direction.

An electrical connector according to an embodiment includes a plurality of signal contacts with an electrically conductive property, a housing with an insulation property, and a shell with an electrically conductive property. The plurality of signal contacts are arrayed along a first direction of the electrical connector and are held by the housing. The shell covers each of a plurality of outer surfaces of the housing that exclude a surface that faces a principal surface of a wiring substrate, and faces a connection part(s) that is/are connected to the wiring substrate on an outer surface of the housing and the plurality of signal contacts, with a gap(s), in a second direction that is a direction along the principal surface of the wiring substrate and is orthogonal to the first direction.

An electrical terminal includes a terminal body, at least one interference lug, and at least one circuit connection part. The terminal body includes a front end and a back end in a longitudinal direction. The interference lug is arranged in parallel to the longitudinal direction and extends outwardly in a horizontal direction perpendicular to the longitudinal direction. The at least one circuit connection part is connected to the terminal body. An electrical connector is also provided, and the electrical connector includes a base and the electrical terminal. The base includes at least one installation trough, and a guiding groove is arranged in the at least one installation trough, the at least one interference lug is adapted to slide into the guiding groove, so as to guide and position the electrical terminal.

A multi-layer circuit board includes a first layer including a first trace, a second layer connected to the first layer and including a second trace, and a stubless interconnect positioned through the first layer and the second layer. The stubless interconnect includes a body that is electrically insulative, and a bridge trace that is electrically conductive and connected to the body, the bridge trace extending from the first trace to the second trace to electrically connect the first trace and the second trace.
