Problems solved by technology

[0006] With this type of circuit board connector, there is a problem that, since the terminals 110A and 110B are press-fitted into and fixed in the connector housing 101, tension is generated between the circuit board and the connector housing due to heat cycle or the like. In the case of poor thermal shrinkage, stress is undesirably generated in the terminals 110A and 110B, possibly causing cracks in the portion of the board fixing portion 117 soldered to the circuit board

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.

Description

technical field [0001] The invention relates to a circuit board connector mounted on a circuit board. Background technique [0002] Examples of this type of circuit board connector are shown in JP-A-2006-100231 and JP-A-2005-116230, for example. Figure 8 is a schematic diagram of a circuit board connector described in JP-A-2006-100231. Figure 9A with Figure 9B is a schematic diagram of the terminals of the connector. [0003] Such as Figure 8 As shown in , the circuit board connector includes: a connector housing 101 made of resin, and a plurality of metal terminals 110A and 110B. port 102; the plurality of metal terminals 110A and 110B are press-fitted into press-fit holes 104 in the rear wall 103 of the connector housing 101 from the rear side, and are fixed therein. [0004] In both terminals 110A and 110B, the Figure 9A The terminal 110A shown in is press-fitted into the terminal press-fit hole 104 in the upper step of the connector housing 101, while Figure 9...
