Abstract: A joint connector (10) has sub-housings (S) (S1 to S6) that can be built up in plural levels. Projecting pieces (31) project on outer sides of the respective sub-housings (S) in directions intersecting a build-up direction (BUD) of the sub-housings (S) and define hand-push portions (13) by building up the sub-housings (S). The sub-housings (S) built up in levels are fit into the intermediate connector (20) by pushing the hand-push portions (13) towards the intermediate connector (20) so that terminal fittings (40) in the joint connector (10) are connected electrically with intermediate terminals (24) in the intermediate connector (20). Identifying projections (A) on the lower mating surfaces of the projecting pieces (31) enter identifying recesses (B) in the upper mating surfaces of adjacent projecting pieces (31) if the sub-housings (S) are built up properly.

Abstract: A board connector (1) has a housing (10) and terminal fittings (20) penetrate through the back wall (11) of the housing (10). A board connecting portion (21) of each terminal fitting (20) penetrates through the back wall (11) and is solder-connected to a board (2). The housing (10) has a heat transfer inhibiting portion for inhibiting heat transfer to the back wall (11). The heat transfer inhibiting portion has a through-hole (13) or heat-insulating grooves (17) in the back wall (11). As a result, heat transfer to the back wall (11) is inhibited and deformation of the back wall (11) due to thermal expansion also is inhibited. Consequently, it is possible to prevent the terminal fittings (20) from separating from the board (2) and going into a state of being not solder-connected thereto.

Abstract: A plurality of terminal fittings 11 are mounted to a housing 20, board connecting portions 13 having mounting portions 14 at lower ends protrude rearward, fixed fittings 30 having mounting plates 32 at lower edges are mounted to opposite side surfaces of the housing 20, and the mounting portion 14 of each terminal fitting 11 and the mounting plates 32 of the fixed fittings 30 are secured to a PCB 40 by reflow soldering. During the reflow soldering, a drawing force toward the PCB 40 acts on each of the terminal fittings 11 and the fixed fittings 30 based on surface tension of molten solder H, but the center of the fixed fitting 30 in the fore/aft direction of the board connecting portion 13 is positioned forward of the center of gravity position O of a connector 10, and rotation moment Mb toward the PCB 40 acts on the front of the housing 20 based on a drawing force Fb on the side of the fixed fitting 30 to prevent the front from being raised.

Abstract: A circuit board connector has metal fixing portions (60) for fixing a synthetic resin housing (10) to a circuit board (K).
