Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel-mounting mechanism for a panel-mounted electrical connector, a so-called panel-mounted electrical connector.

2. Description of the Related Art Conventionally, electrical connectors that are attached to a panel have been fixed to the panel using screws or the like.

However, in order to fix the connector to the panel with screws or the like, it is necessary to provide several holes or taps for fixing the screws on the connector and the panel.

When attaching the connector to a panel, it is necessary to align the mounting position correctly, and the screw fixing holes or taps on the panel and connector must be manufactured with high precision for alignment. In addition, several screw holes, tapped holes, etc. are required, so it takes time and effort to align screw-sized screws and tighten screws with tools such as a screwdriver, which also costs money. It had drawbacks.

The purpose of the present invention is to eliminate such conventional drawbacks and provide a panel mounting frame for electrical connectors that makes it very easy to attach electrical connectors to panels. .

In panel mounting according to this invention, the frame body is a connector unit) f
The receiver has a through opening for insertion, has a protrusion having a tapered surface on at least a part of its outer periphery, and has a structure in which a stopper is formed behind the protrusion on the opposite side from the tapered surface. To attach the panel to which the electrical connector is to be attached, simply insert the entire frame into the opening, and the frame itself elastically shifts inward due to the engagement between the side edge of the opening and the tapered surface. In the mounting, the side edge of the opening extends over the entire protrusion and fits into the retaining groove, thereby fixing the mounting to the panel.

Therefore, if the panel mounting according to the present invention extends around the entire circumference of the frame, the electrical connector can be mounted on the panel by simply inserting the connector unit into the through opening of the frame, and at that time, Since there is no need for labor such as positioning screw-sized screws or tightening screws, and there is no need for any tools such as a screwdriver, the connector can be attached to the panel extremely easily.

Next, the present invention will be described in more detail with regard to embodiments of the present invention based on the accompanying drawings.
