Structure for provisional locking of terminal of connector

摘要

A bevel portion extends from a front end of a plate-like electrical contact of the terminals to a lengthwise intermediate portion of the electrical contact, the bevel portion residing at an intersection of a width surface of the electrical contact with a thickness surface of the electrical contact. A step portion resides at an end of the bevel portion at the lengthwise intermediate portion of the electrical contact, the thickness surface extending in the thickness direction having one portion with reduced width defined by the bevel portion in the thickness direction. The other portion of the thickness surface continuing to an end of the step portion has an increased width in the thickness direction to define a press-fit portion. The electrical contact is inserted in a hole of a housing to the extent defined by the step portion and thereby provisionally locked with the press-fit portion press-fitted in the hole.

主权项

1. A structure for provisional locking a terminal of a connector, comprising:
a bevel portion extending from a front end of a flat-shaped electrical contact of the terminal to an intermediate portion of the electrical contact along a length of the electrical contact,
the bevel portion being provided at an intersection of a widthwise surface of the electrical contact with a thickness surface of the electrical contact,a provisional locking portion of the thickness surface having a reduced width,
the reduced width being defined by presence of the bevel portion; a step portion provided at an end of the bevel portion at the intermediate portion of the electrical contact; and a press-fit portion defined by another portion of the thickness surface starting from the step portion and continuing in a rearward direction of the provisional locking portion of the thickness surface,
the press-fit portion being thicker than the reduced width of the provisional locking portion of the thickness surface, wherein the provisional locking portion is partitioned from the press-fit portion by the step portion that extends in a width direction of the electrical contact, the step portion being formed as a planar boundary surface between two distinct planes, wherein, the provisional locking portion is configured such that, when the electrical contact is inserted into a hole of a housing to a location where the step portion is provided, the thickness surfaces having the reduced width of the provisional locking portion on both widthwise sides of the electrical contact are contacted with side surfaces of the hole on both sides, respectively, thereby the provisional locking portion is provisionally locked to the hole by a frictional resistance, and wherein the press-fit portion is configured to be press-fitted into the hole after the provisional locking portion is provisionally locked to the hole.
