The present document provides an electrical box, wherein the electrical box comprises: a first circuit comprising a first power input interface at one end of the first circuit and a first power output interface at another end of the first circuit; a second circuit comprising a second power input interface at one end of the second circuit and a second power output interface at another end of the second circuit; and a third circuit electrically connected to the first and second circuits and comprising a third power output interface at one end of the third circuit.

The present disclosure provides a cooling casing and a cooling device applied to a vehicle and an in-vehicle server. The cooling device applied to the in-vehicle server includes: a first housing and a second housing, an accommodating cavity is formed between the first housing and the second housing; and a cooling duct, the cooling duct being spirally disposed in the accommodating cavity, two ends of the cooling duct are connected to an external cooling system, and the cooling duct is filled with cooling liquid. The present disclosure is simple in structure and low in costs, and can effectively resolve the heat dissipation problem of the in-vehicle server.

A resin structure includes a first resin body, and a second resin body. The second resin body is fit to an outer surface of the first resin body while being slid to one side in a sliding direction along the outer surface of the first resin body. The first resin body and the second resin body form a water stop structural unit extending in the sliding direction in a state where the second resin body is fit to the first resin body. The water stop structural unit includes a first water stop structure in a first region located at the one side in the sliding direction, and a second water stop structure in a second region located at the other side in the sliding direction with respect to the first region.

There is disclosed an electrical connection unit for a refrigeration system comprising: a container defining an interior for containing electrical circuitry, the container having an external port configured to couple with an external connector; a closure moveable relative to the container between a closed configuration in which access to the interior is prevented, and an open configuration in which access to the interior is permitted. The closure has a locking portion defining a connector opening for receiving the connector, configured so that movement of the closure to the open configuration is prevented by interlocking engagement of the connector and the closure. There is also disclosed an associated method of coupling or decoupling a connector and an electrical connection unit.

An in-vehicle electrical component circuit unit : includes an electrically insulative holding body configured to hold a circuit member ;a plate wall portion configured to cover a casing through hole provided in an in-vehicle electrical component ; a connector including a connection member that is held by the plate wall portion ; and a sealing member (126) that is provided on a first surface , which is a surface of the plate wall portion that is to be attached to the casing (132), and is configured to come into contact with a peripheral edge of the casing through hole , wherein a portion of the connection member that protrudes on a first surface side includes a circuit-side connection portion (120), the circuit-side connection portion is detachably connectable to the circuit member , and the circuit-side connection portion is inserted into the casing through hole from outside the casing and connected to the circuit member

A switch assembly is configured to be mounted to a lower cover of the junction box assembly. The switch assembly includes a holder, the holder is configured to removably coupled to the lower cover. The holder includes a pocket. The switch assembly further includes a switch. The hook is configured to engage the lower cover and is dimensioned to be seated within the pocket of the holder. The switch includes a hook. The hook is configured to pull the switch towards the lower cover so as to pinch the holder between the lower cover and the switch. Accordingly, the hook presses the switch against a bottom surface of the lower cover so as to eliminate a rattle when the switch is held in suspension beneath the lower cover of the junction box assembly.

Provided is an electric connection box with which proactive measures can be taken by liquid inflow monitoring. The electric connection box includes a housing where an electronic component is mounted. The housing is provided with a detection part detecting liquid inflow.

Provided is an electric connection box that can be removed with ease and safety. The electric connection box has a housing where an electronic component is mounted. Adhering portions adhering to an object is provided on an outside surface of a bottom plate of the housing. The adhering portions have reduction portions reduced in area toward at least one end portion of the housing.

Provided is an electric connection box with which the workability of assembly work can be enhanced and the occurrence of problems attributable to forgetting to close a cover can be prevented. A vehicular electric connection box includes: a housing having a connecting portion including a terminal connected to an external bus bar; and a cover member opening and closing the connecting portion, in which the cover member has a lid portion exposing or shielding the terminal with the cover member closed.

A power distributor of an electrical system of a motor vehicle, including a circuit board, which has a main connection to a main circuit and multiple secondary connections. Each secondary connection is assigned to one secondary circuit and electrically contacted with the main connection via a respective circuit breaker that has two connections. The two connections of each circuit breaker are electrically contacted directly with the circuit board.
