At least a part of the ventilation passage (8) is constituted by a groove (40) formed in at least one of mutually overlapping surfaces (411, 611) of the first core (4) and the second core (6). An outer vent (81) of the ventilation passage (8) is formed at a position closer to the case (12) than the receptacle (71) in a Z direction.

The invention relates to an electrical connection system for an electrical appliance, such as a terminal block (7), the electrical connection system (7) comprising a conductive strip (21) comprising two connecting branches (63a, 63b) arranged so as to cooperate with a conductive portion (13) of an electrical conductor (13) in a connecting position and having a cooperating area (35) arranged so as to cooperate with a portion (15) of a support rail (15) in a cooperating position, a leaf spring (23), and a holding device (49) arranged so as to hold the portion (15) of the support rail (15) in contact between the two cooperating branches (63a, 63b) in the cooperating position, at least one connecting branch (63a, 63b) having a cross-opening (69a, 96b) designed so that a portion of the holding device (49) passes therethrough in the cooperating position.

A terminal block includes a display-use moveable member which has a main body portion that can reciprocate in the direction intersecting a terminal connection surface and a contact moveable portion that extends along a guide surface, has a first end portion in an extension direction that is disposed so as to come into contact with a conductor portion in an electric wire passage portion and move in a first direction away from the terminal connection surface, and has a second end portion in the extension direction that is connected to the main body portion, and moves in an array direction in response to movement of the first end portion in the first direction to move the main body portion in a second direction toward the terminal connection surface.

A connector structure includes a case seat assembly and plug assemblies. Two ends of the case seat assembly are formed with channels. Each plug assembly has a conductive section and a wire connection member. The wire connection member is formed with a receiving space for receiving a pressing leaf spring. Each pressing leaf spring has an abutment end. A lateral protrusion section is disposed on the abutment end. Multiple unlocking assemblies are disposed beside the wire connection member. Each unlocking assembly has a push member formed with a push block. The lateral protrusion section is positioned in a sliding path of the push block along the channel, whereby the lateral protrusion section can be pushed to drive the abutment end to release a conductive wire.
