摘要： To prevent an increase of stresses in soldered portions between terminals and a circuit board during thermal expansion. Movable holding portions 17 which are elastically deformable are formed in a plate main body 13 of an alignment plate 12. The movable holding portions 17 are connected with the plate main body 13 via connection portions 18. Positioning holes 15 for aligning terminals 11 are formed in each movable holding portion 17. Even if the plate main body 13 is displaced with respect to a circuit board P due to thermal expansion with the terminals 11 fitted in and soldered to connection holes of the circuit board P, such a relative displacement is corrected by the elastic deformation of the movable holding portions 17 and the connection portions 18 and, accordingly, the positioning holes 15 are held in specified positions with respect to the connection holes. Therefore, there is no likelihood that stresses in the soldered portions increase due to the displacement of the positioning holes 15 with respect to the connection holes.

摘要： To improve operability during the insertion of a retainer and a function of locking terminal fittings when the retainer is in its full locking position. ÄSolutionÜ In a connector having a retainer 13 which is insertable through one side surface of a housing 11 and provided with forked locking arms, the width and/or thickness of partial locking arms 13a are set smaller than those of full locking arms 13b to thereby set the elastic forces of the partial locking arms 13a smaller than those of the full locking arms 13b.

摘要： A holding tool (40) is inserted into a retainer-attaching hole or a holding tool-accommodating space (22) with the holding tool (40) supporting a short-circuit terminal (15) therein. The short-circuit terminal (15) is inserted into a cavity (14) in a connector housing (10) by pushing a rear end of the terminal (15) through a handling aperture (23) by means of a pushing pin (45). Since the terminal (15) is inserted into the connector housing (10) from its lower side, a front opening of the cavity (14) can be formed into the smallest size so that a short-circuit-releasing member (31) can enter the opening (20). Extraneous substances hardly enter the cavity (14) in the connector housing (10) through the opening (20). Also, since the handling aperture (23) may be formed into the smallest size so that the pushing pin (45) can enter the aperture (23), the connector housing (10) becomes a small size. Thus, the connector housing (10) can be prevented from becoming a large-sized configuration and from entrance of the extraneous substances through the front opening (20) of the cavity (14).

摘要： A retainer (10) for insertion into a connector housing of an electrical connector to retain electrical terminals in position in the housing, has a retainer body (11) and flexible locking bars (14F, 14R) for locking the retainer (10) to a connector housing (20) at two predetermined insertion positions thereof. The retainer body (11) comprises through-holes through which terminals are inserted, and engaging portions for preventing the terminals inserted into the connector housing from being moved in a return direction. The flexible locking bars (14F, 14R) form a part of and are co-planar with side walls of the retainer body (11), and are located within the extent of the through-holes in the retainer insertion direction. Each bar (14F, 14R) has a free end carrying a locking nose (16F, 16R). The locking noses (16F, 16R) are recessed into the retainer, relative to the outer faces of the side walls.

摘要： A terminal fitting (1) has connecting portion (5) with an engaging portion (14) to be engaged with a resin lock (13) of a connector (3). The engaging portion (14) projects with a step from an upper wall (12) to ensure a large engaging area with the resin lock (13). An outer edge (14A) of the engaging portion (14) is closer to the resin lock (13) than an inner edge (14B) thereof. Thus, when the terminal fitting (1) is pulled back in withdrawing direction, a force acts to move the leading end of the resin lock (13) from the outer edge (14A) of the engaging portion (14) toward the inner edge (14B). Therefore, the terminal fitting (1) is difficult to disengage from the resin lock (13), and a large engaging force is secured.
