Description

  The present invention relates to a structure that protects against an external force applied to a jack attached to a main body in order to connect to an external connection device while avoiding an increase in size of an electronic device.

  Conventional electronic devices are provided with various jacks for connecting to external connection devices, and plugs provided in the external connection devices and cable bushes are connected to the jacks. When the jacks and plugs are connected only by their fittings, the plugs can be easily pulled out or destroyed when the plugs are subjected to external force.

  For this reason, some externally connected devices and cable bushes have protrusions in addition to plugs, and electronic devices have a recess that corresponds to the protrusions of externally connected devices so that they can be fitted. . By doing so, the force from the direction substantially perpendicular to the insertion direction can be received by the fitting part of the external connection device or the convex part of the cable bush and the concave part of the electronic device, thereby preventing the destruction of the jack or the plug. it can.

  In some cases, the concave portion disposed in the electronic device is not disposed in the electronic device itself, but another component having a concave portion corresponding to the convex portion of the external connection device or the cable bush is attached to the electronic device. Further, when the protrusion shape is a male screw and the concave portion is a female screw portion, it is possible to attach more firmly by tightening and to receive the insertion direction of a jack or a plug.

  In addition, in order to simply fix without tightening the male screw, the electronic device has a shape that sandwiches the male screw instead of the female screw part, and further suppresses the shape that the jack lid is pinched in conjunction with the insertion of the plug Some of them are prevented from coming off (see Patent Document 1).
