Stack-type wire mount wafer connector and connector assembly

A stack-type wire mount wafer connector for fitting along a fitting direction, and electrically connecting a plurality of wires, to a fitting connector and including a wafer that is stackable and electrically insulated, the stack-type wire mount wafer connector comprising:

• a first base portion and a second base portion extending between a first side portion and a second side portion facing each other and extending between a first end portion and a second end portion facing each other, the first base portion and the second base portion defining cavities between the first base portion and the second base portion;
• a first end surface provided at the first end portion, the first end surface being configured to receive the plurality of wires;
• a second end surface provided at the second end portion, the second end surface being configured to be fitted to the fitting connector;
• a first side surface provided at the first side portion;
• a second side surface provided at the second side portion;
• a latch portion being integrally formed with the wafer, and extending along the second side surface of the wafer;
• at least one protrusion extending outward along a thickness direction (Z-axis) of the wafer from the first base portion of the wafer;
• and
• at least one opening portion into which at least one protrusion of another stack-type wire mount wafer connector is to be inserted;
• wherein
• when the at least one protrusion of the another stack-type wire mount wafer connector is inserted into the at least one opening portion of the stack-type wire mount wafer connector to form a stacked connectors, slippage between the stack-type wire mount wafer connector and the another stack-type wire mount wafer connector in the fitting direction (X-axis) of the fitting connector is prevented, so that when the stacked connectors is fitted to the fitting connector and the latch portion of each of the stack-type wire mount wafer connectors is in latched state, then neither of the stack-type wire mount wafer connectors can be unfitted from the fitting connector unless both of the latch portions are put in unlatched state.
