A sealed electrical enclosure for housing an electrical component is provided. In one exemplary embodiment, the sealed electrical enclosure includes a housing, a first and second electrical connector, an actuator, and a terminal. The housing has a sealed interior when a top portion is coupled to a bottom portion. The first electrical connector extends from the sealed interior through the bottom of the housing and is electrically coupled to the electrical component. The actuator extends from the sealed interior through the housing and is configured to manipulate the electrical component. The terminal is electrically coupled to the second electrical connector. The second electrical connector is configured to mate with the first electrical connector. The first and second electrical connectors are configured to be connected and disconnected to attach and remove the housing to and from the terminal.

An improved bus bar apparatus is usable in high temperature electrical terminations and is configured to provide sufficient heat dissipation such that when connected at one end with a 90 C. wire, the bus bar apparatus is at most only at 75 C. at another end thereof, which end can be connected with a lower temperature electrical component such as a circuit interrupter. The bus bars apparatus may include bus bars that extend directly between the high temperature wires and the low temperature electrical component, or the bus bar apparatus may additionally include wires that are electrically interposed between the low temperature region of the bus bars and the electrical component. Additional cooling could be provided by employing oversized wires. The bus bars may additionally include fins, fans, or supplementary heat sinks to enhance thermal convection of the bus bar. The bus bar apparatus additionally can be provided with its own enclosure to be usable in a retrofit situation.

A method for establishing a plug connection, and a method for strengthening a plug connection, wherein a connecting zone is welded with a laser beam which passes through a surrounding housing owing to transparency.

A stackable connector system having upper and lower members is provided. The upper member has a first set of upper connections including studs or jacks and a second set of upper connections including studs or jacks that are opposite the first set of upper connections. The lower member includes a first set of lower connections including studs or jacks that are opposite the second set of upper connections. The second set of upper connections and the first set of lower connections have parallel axes that are misaligned in an unplugged state. The misalignment creates deformation of the upper member and/or lower member during insertion of the studs into the jacks when the second set of upper connections and the first set of lower connections are plugged together. The deformation creates a resultant force between the second set of upper connections and the first set of lower connections.

An explosion proof connector is provided with first and second electrical connectors and first and second threaded sidewalls that surround the electrical connectors. The threaded sidewalls engage to secure the electrical connectors in electrical connection. Either the first threaded sidewall is rotatable relative to the first electrical connector or the second threaded sidewall is rotatable relative to the second electrical connector. A ratchet lock is carried by the first sidewall, and a ratchet surface is carried by the second sidewall, the ratchet lock being releasable and biased toward engagement with the ratchet surface. The ratchet lock permits rotation of the second sidewall relative to the first sidewall in a first direction and prevents rotation of the second sidewall relative to the first sidewall in a second direction. A release mechanism disengages the ratchet lock and permits the second sidewall to rotate in the second direction relative to the first sidewall.

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 battery module includes a cell assembly including at least one battery cell, a module case in which the cell assembly is accommodated, and a connector mounted on the module case. The connector includes a connector terminal for electrical connection with the battery cell, a connector housing surrounding the connector terminal, and a connector header body coupled to the connector housing and mounted on the module case in such a manner that at least a part of the connector header body is inserted into the module case. The connector header body is formed of a heterogeneous laminate material including a heat-resistant metal material with a melting point of 1000 C. or higher and a lightweight metal material lighter than the heat-resistant metal material.
