Embodiment Construction

[0021] refer to Figure 1-11 , describing a connector according to the invention. The connector includes a housing 10 made of synthetic resin and terminal fittings 30 inserted into the housing 10 from behind. In the following description, the width direction and the lateral direction mean the same as each other. In addition, the elastic deformation direction and the vertical direction of the locking lance 12 mean the same as each other.

[0022] Such as Figure 1 to Figure 5 As shown, a terminal accommodating cavity 11 is formed in the housing 10, and the terminal fitting 30 is viewed from the rear (from Figure 2-4 on the right side) into the terminal accommodating cavity 11. Such as Figure 2-4 As shown, the terminal fittings 30 are long and narrow female terminals in the front-rear direction. A rectangular tube 31 is formed on a front end portion of the terminal fitting 30 , and a rectangular locking hole 33 is formed on a widthwise middle portion of a bottom surface ...

Abstract

The present invention relates to a connector, comprising: a housing (10), the housing is made of synthetic resin, and forms a terminal holding cavity (11). The elastically deformable locking spear shaft is formed forward along the inner wall surface of the terminal holding cavity to form a cantilever, and the locking bulge (15) is formed on the locking spear shaft. The terminal connector (30) is inserted from the rear into the terminal holding cavity, and has a locking protrusion (34), the locking protrusion is constructed: when the terminal connector is inserted into the terminal accommodating cavity, the locking protrusion (34) is engaged with the locking bulge (15). Reinforcing ribs (20) are integrally formed on the locking spear shaft, and protrude in the direction of the elastic deformation of the locked spear shaft in the direction opposite the terminal housing cavity.

Description

technical field [0001] The invention relates to a connector. Background technique [0002] JP2009-104863 discloses a connector, including a housing formed with a terminal accommodating cavity, an elastically deformable locking lance that forms a cantilever forward along the inner wall surface of the terminal accommodating cavity, and a terminal that will be inserted into the terminal accommodating cavity from the rear connector. The terminal fitting includes a locking hole, and the locking lance includes a locking protrusion. When the terminal fitting is inserted into the terminal accommodating cavity, the locking projection enters into the locking hole, and engages the edge of the locking hole to hold the terminal fitting against backward movement. [0003] In the connector as described above, if the terminal fitting held by the locking lance is pulled backward, the locking projection will be inserted deeper into the locking hole, and the locking lance will be warped so t...
