Abstract

An object of the present invention is to provide a connector in which a terminal fitting can be reliably attached to a housing, the terminal fitting has a high pull-out strength, and the assembly workability is good. Equipped with a housing, terminal fittings and locking pieces, the housing has a through terminal receiving hole, the terminal receiving hole has a locking step difference part and a claw locking part, the terminal fitting has a contact part on the front side, and a mounting part on the rear side. The elastic locking piece protruding from the side of the terminal fitting toward the rear end side of the wire for electrical connection, the locking piece has a terminal drop-off prevention part and a locking claw, so that the terminal fitting is inserted into the terminal receiving hole of the housing from the front side The elastic locking piece is locked on the locking step, and the terminal drop-off prevention part of the locking member is inserted into the terminal receiving hole of the housing along the outer periphery of the terminal fitting, so that the locking claw is locked on the claw locking part. , the terminal fall-off preventing portion prevents the terminal fittings from falling off from the terminal accommodating hole.

Description

technical field [0001] The present invention relates to a connector with high drop-off resistance of terminal fittings, which is suitable for use in a transition connector for connecting a light source lamp such as a liquid crystal projector to a high voltage power supply side, for example. Background technique [0002] As a connector for electrical connection, known technologies such as Figure 10 As shown in (a), the elastic locking piece 152 (lance) is formed by cutting out the terminal fitting 150 of the connector 130, and is locked on the locking step 134 provided in the terminal receiving hole 133. The terminal fitting 150 is installed in the terminal accommodating hole 133 by the elastic locking piece 152 . [0003] But Ruo Ru Figure 10 As shown in (b), the elastic locking piece 152 is plastically deformed to lose its spring elasticity or Figure 10 As shown in (c), due to insufficient insertion of the terminal fittings 150, the elastic locking piece 152 cannot be co...
