[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a receptacle connector mounting structure mainly used in an I / O section of a computer, a control device, etc., and to a casing such as a panel. Specifically, the present invention also has an EMI shield and is suitable for downsizing and robustly. The present invention relates to a structure for attaching a receptacle connector that can be attached to a body to a housing and a connector device.
[0002]
[Prior art]
In the prior art, I / O connectors for computers have almost the following structure.
[0003]
That is, in the prior art, screws are used to fix the receptacle connector and the panel, and the connector is fixed to the panel by the tightening force of the screw, and a space is required for securing the screw structure. I came.
[0004]
FIG. 11 is a perspective view showing a connector dropout prevention device according to the prior art, and FIGS. 12A, 12B and 12C are plan views for explaining the operation of the connector of FIG. No. 21107, hereinafter referred to as prior art 1). 11 and 12, the male connector M is attached to the base 106. The screw 103 protrudes from the male screw portion through insertion holes opened at both longitudinal ends of the male connector M. The engagement metal fitting 102 has a disk-shaped engagement protrusion 101 at one end in the axial direction and a female screw portion at the other end. The female screw portion of the engagement fitting 102 is formed so as to be able to be screwed into the male screw portion of the screw 103.
[0005]
FIG. 12A shows a state in which a pair of engagement fittings 102 are screwed and fixed to both ends in the longitudinal direction of the male connector M with screws 103. It can be connected and fixed as it is to a female connector F having a slide fitting 104 as shown in FIG. Here, the slide metal fitting 104 is slidable between a position where it engages with the engagement protrusion 101 of the engagement metal piece 102 and a position where it does not engage.
[0006]
Next, in the state shown in FIG. 12 (a), when the female screw portion of the engagement fitting 102 is detached from the male screw portion of the screw 103, the male screw portion of the screw 103 becomes the male screw portion as shown in FIG. 12 (c). since screws 103 at both ends in the longitudinal direction of the mold connector M is the same state as that protrudes, in which it is possible to screw-fastened to the female screw boss 10 5.
[0007]
On the other hand, a connector locking device as shown in FIG. 13 has been proposed (refer to Japanese Patent Laid-Open No. 6-13131, hereinafter referred to as Prior Art 2).
