BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting electronic devices to each other, and more particularly to a connector having a metal shell for preventing electromagnetic interference and a guide for facilitating fitting of the connector. Is.

[0002]

2. Description of the Related Art An example of a conventional connector of this type is shown in FIG.
As shown in FIG. 5, the fitting portion is composed of a receptacle-side connector 63 and a plug-side connector 64 which are covered with metal shells 61 and 62 each having an elongated trapezoidal opening surface. In the receptacle-side connector 63 and the plug-side connector 64, metal shells 61 and 62 are fixed to the side surfaces of horizontally long insulator blocks 65 and 66, respectively.

A male pin array 67 is provided in the metal shell 62 of the plug-side connector 64, and round pins 68 for guiding are provided on both sides thereof. The male pin array 67 and the guide round pin 68 are respectively implanted in the insulator block 66. On the other hand, in the metal shell 61 of the receptacle-side connector 63, a contact array 69 that receives the male pin array 67 is provided.
Further, on both sides of the contact array 69 in the metal shell 61, round holes 70 into which the guide round pins 68 of the plug side connector 64 are fitted are provided. The guide round pin 68 and the round hole 70 are formed so that they can be easily fitted to each other.
The tip of the round pin 68 is chamfered so as to be gradually thin, and the round hole 70 is also chamfered so that the diameter of the hole increases at the opening surface of the metal shell 61.

[0004]

In the plug-side connector 64 of such a conventional connector, the metal shell 6 is used.
It is necessary to provide a space around the round pins 68 for guides provided on both sides of the male pin array 67 in 2 in order to fit into the round holes 70 in the metal shell 1 of the receptacle-side connector 63. There is a drawback that the entire connector, especially the lateral length, becomes large. Further, in the above-described conventional connector, as shown in FIG. 7, when the plug-side connector 64 is pulled out first with respect to the receptacle-side connector 63, one end (the right end in the figure) of the plug-side connector 64 is opposite. Since the guide round pin 68 at the end (the left end in the drawing) is inclined in the round hole 70, a large disengagement force may be required or the round pin 8 may be deformed in some cases. Therefore, an object of the present invention is to eliminate the above-mentioned conventional drawbacks and to provide a connector having a guide which is small in size and easy to connect and disconnect.

[0005]

According to the present invention, in a connector composed of a receptacle-side connector and a plug-side connector, each of which has a fitting portion covered with an elongated metal shell, the receptacle-side connector has a substantially rectangular opening surface. The metal shell of the plug-side connector is a rectangle of the receptacle-side connector, and the metal shell of the plug-side connector has a rectangular shape. There is provided a connector with a fitting guide characterized in that the connector has a substantially trapezoidal opening surface capable of receiving both the metal shell and the protrusions provided on both sides thereof.

According to the present invention, the tip of the protrusion projects in the fitting direction from the opening surface of the metal shell, and the outer peripheral surface excluding the surfaces adjacent to both ends of the metal shell is directed toward the tip. It is chamfered to incline toward.

That is, the metal block 15 shown in FIG. 2 and a metal block (not shown) having a substantially symmetrical shape are arranged at both ends of the metal shell 12 in the longitudinal direction, and the protrusions 14 and the metal shell 12 of these metal blocks 15 are arranged. And form a horizontally long trapezoid.

Further, the projection 14 has a tip projecting from the opening surface of the metal shell 12 in the fitting direction, and an outer peripheral surface 21 except the surfaces 20 adjacent to both ends of the metal shell 12 is inclined toward the tip direction. Chamfered to do.
Female screw holes 22 and 23 for screwing to a panel of an electronic device or a printed circuit board (not shown) are provided on the upper surface and the side surface of the metal block 15. Although not shown in FIG. 2, the metal block 15 further has a chamfered corner portion (for example, shown as 24 and 25 in FIG. 3).
Therefore, the insulator block 11 can be easily inserted and positioned easily. Connection lead 2 of contact 13
6 is taken out from the rear surface of the insulator block 11 and then bent downward at a right angle.
Positioned and fixed by.

FIG. 3 is a view showing the structure of the end portion of the metal shell 12 in the receptor side connector, (A) being a front view,
