The invention discloses a steering wheel switch gap adjusting structure which comprises a shell, a socket connected with the shell in a clamped mode and a PCB arranged on the socket, the socket is provided with a set of elastic pieces for supporting the PCB, the socket is further provided with a set of supporting bosses for limiting the lower limit of the PCB, and the shell is internally provided with a set of pressing columns for limiting the upper limit of the PCB. The elastic pieces have arch structures, and the two ends of the elastic pieces are fixedly arranged on the socket. The steering wheel switch gap adjusting structure can solve problems that the PCB is not tightly fixed due to assembly and manufacturing errors of the switch shell and the socket and the gap between the switch shell and the socket is increased due to creep deformation of a plastic part used for a long time, guarantees the assembly reliability of the PCB, avoids abnormal sound, and can be widely applied to the field of steering wheel switches.
本发明公开了一种方向盘开关间隙调节结构,包括外壳,与外壳卡接的插座,设置在插座上的PCB板,所述插座上设置有一组支撑PCB板的弹性片,所述插座上还设置有一组限制PCB板下极限的支撑凸台,所述外壳内设置有一组限制PCB板上极限的压柱。所述弹性片为拱形结构,其两端固定设置在插座上。本发明能够解决开关外壳与插座装配和制造误差造成PCB板固定不紧以及长期使用塑料件蠕变造成的相互间间隙增大的问题,保证PCB板装配的可靠性,避免发生异响,可广泛应用于方向盘开关领域。
