Abstract

A circuit board connector is provided. The circuit board connector includes: a connector housing which is mounted on a circuit board; and a terminal which is press-fitted into the terminal press-fitting hole of the connector housing. The terminal includes: a terminal connecting portion which is disposed through the rear side of the connector housing to be connected to a mating connector; a press-fitting portion to be fixed to the connector housing; a board fixing portion fixed to the circuit board by soldering; and a coupling portion extending and bent toward a side of the circuit board to couple the press-fitting portion with the board fixing portion. The circuit board connector also includes a stress absorbing portion provided with a center hole which is provided on a midway of the coupling portion so as to absorb a stress by being deformed.

Claims

1. A circuit board connector, comprising:

a connector housing which is mounted on a circuit board and is provided with a fitting port for fitting a mating connector at a front side and a terminal press-fitting hole at a rear side; and

a terminal which is press-fitted into and fixed to the terminal press-fitting hole and which includes;

a terminal connecting portion which is disposed through the rear side of the connector housing and extends therefrom toward the front side so as to be connected to a terminal of the mating connector;

a press-fitting portion which is continuous from the terminal connecting portion to be fixed to the connector housing by being press-fitted in the terminal press-fitting hole;

a board fixing portion which is fixed to the circuit board by soldering;

a coupling portion which extends and is bent toward a side of the circuit board to couple the press-fitting portion with the board fixing portion, and

a stress absorbing portion formed of a square frame shape and provided with a center hole which is provided on a midway of the coupling portion so as to absorb a stress by being deformed;

wherein the coupling portion includes;

a first straight portion extending linearly on an extension of the terminal connecting portion and the press-fitting portion;

a first bent portion bent from a rear end of the first straight portion toward the side of the circuit board;

a second straight portion extending linearly from the first bent portion toward the circuit board; and

a second bent portion bent from a lower end of the second straight portion in a direction toward the front side or a direction toward the rear side parallel to the circuit board, the board fixing portion being provided on an extension of the second bent portion, and

wherein the stress absorbing portion is provided midway in the first straight portion such that a penetrating direction of the center hole is directed in a vertical direction, first opposing two sides thereof are oriented substantially parallel to a front-back direction, and remaining second opposing two sides thereof are oriented substantially parallel to a left-right direction.

2. The circuit board connector according to claim 1, wherein an outer width between the second opposing two sides of the stress absorbing portion is made greater than a width of the first straight portion.

3. The circuit board connector according to claim 1, wherein an inner width between the second opposing two sides of the stress absorbing portion is made greater than a width of the first straight portion.

4. A circuit board connector, comprising:

a connector housing which is mounted on a circuit board and is provided with a fitting port for fitting a mating connector at a front side and a terminal press-fitting hole at a rear side; and

a terminal which is press-fitted into and fixed to the terminal press-fitting hole and which includes;

a terminal connecting portion which is disposed through the rear side of the connector housing and extends therefrom toward the front side so as to be connected to a terminal of the mating connector;

a press-fitting portion which is continuous from the terminal connecting portion to be fixed to the connector housing by being press-fitted in the terminal press-fitting hole;

a board fixing portion which is fixed to the circuit board by soldering;

a coupling portion which extends and is bent toward a side of the circuit board to couple the press-fitting portion with the board fixing portion, and

a stress absorbing portion provided with a center hole which is provided on a midway of the coupling portion so as to absorb a stress by being deformed;

wherein an accommodating portion for accommodating the stress absorbing portion is provided in the rear of the terminal press-fitting hole of the connector housing, such that a clearance is provided between the accommodating portion and the stress absorbing portion.
