Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] Regarding an interface connector used in an information processing electronic device or the like, a connector case is fitted to a mating connector of the connector for the purpose of enabling attachment / detachment of a plastic case covering a metal cover of the connector. In a connector cover including a metal cover that covers the outer periphery excluding the mating surface and a plastic case that covers the metal cover, notches are provided at four corners of the surface of the metal cover that faces the mating connector, and the plastic case has A locking projection for locking the notch is provided at a position corresponding to the notch of the metal cover on the inner side, and a wall having the locking projection can be bent outward so as to bend outward. The slits are provided at four places.

[Industrial applications]

The present invention relates to an interface connector used in an information processing electronic device or the like, and particularly to a connector cover thereof.

[Conventional technology]

The interface connector is generally covered with a metal cover to prevent electromagnetic noise. Some devices have a metal cover covered with an insulator to protect the device from electrostatic discharge. FIG. 3 shows a conventional connector cover including this metal cover and an insulator (plastic) case covering the metal cover. In the figure, 1 is a connector body having a large number of contacts (shown by two-dot chain lines), 2 is a metal cover that covers the outer periphery of the connector body except the mating surface of the mating connector, and 3 is the metal cover. It is a plastic case. Reference numeral 4 is an engagement piece for preventing the slip-out, which has a claw that engages with the mating connector when fitted to the mating connector.

In such a connector cover, the plastic case 3 is fixed to the metal cover 2 by attaching a stopper piece 5 as shown in FIGS. A method of penetrating the hole 6 and fixing it by a catch 7 provided on the plastic case 3 or a method of molding from the metal cover is adopted.

[Problems to be solved by the device]

In the above-mentioned conventional connector cover, in the method of fixing a plastic case to a metal cover as shown in FIG. 3, once fixed, it cannot be removed unless either the plastic case 3 or the metal cover 2 is destroyed. There was a problem that we could not handle mistakes.

In addition, the method of molding from the top of the metal cover 2 also has the drawback that the plastic cover cannot be removed, the mold for molding is complicated, and the cost is high.

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a connector cover in which a plastic case for covering a metal cover of a connector can be attached and detached.

[Means for solving the problem]

In order to achieve the above object, the connector cover of the present invention comprises a metal cover for covering the outer periphery of the connector except the joint surface with the mating connector, and a plastic case for covering the metal cover.
Notches 13 are provided at four corners of a surface of the metal case 10 opposite to the mating connector, and the plastic case 11 is locked inside the metal cover 10 at a position corresponding to the notch 13 of the metal cover 10. The present invention is characterized in that the projections 14 are provided and the slits 15 are provided at four points on the side surface of the case so that the wall having the locking projections 14 can be bent outward.

[Action]

By providing the projections 14 that engage with the metal cover 10 on the surface of the plastic case 11 facing the mating connector and the slits 15 provided at the four corners of the surface, the wall of the plastic case 11 having the projections 14 is elastic. And can be attached to and detached from the metal cover 10 by pushing the wall outward.

〔Example〕

FIG. 1 is a view showing an embodiment of the present invention, (a) is an exploded perspective view, and (b) is an assembled sectional view.

In FIG. 1 (a), 10 is a metal cover, 11 is a plastic case, and the metal cover 10 has two upper and lower parts 10a and 10a.
The connector body (not shown) is formed by being divided into b parts, and can be coupled so as to cover the entire circumference of the mating connector except its mating surface.

Further, on one side surface of the cover 10a, engaging pieces 12, 12 'are provided to engage with and engage with a projection formed on the mating connector when mating with the mating connector. Also, cutouts are provided in the corners of the faces of the covers 10a and 10b facing the mating connectors.
13 are formed.

The plastic case 11 has a tubular shape with a rectangular cross section so as to cover the metal cover 10, and projections 14 capable of engaging with the notches 13 of the metal cover 10 are formed at the four corners of one opening of the plastic case 11. A slit 15 is formed on the side surface in the vicinity of the protrusion 14. A stopper 16 is provided inside the case 11.

The metal cover 10 and the plastic case 11 formed in this way are assembled as shown in FIG. 1 (b) by fitting the plastic case 11 to the metal cover 10 in the direction of arrow A. As shown in FIG. 2, this fitting is performed by the upper and lower walls having the protrusion 14 of the plastic case 11.
Bend 11a and 11b outwards as shown by the arrows and fit them on the metal cover 10, and the projection 14 falls into the notch 13 and the stopper 16
Push it in until it touches. Incidentally, the wall 11a having the protrusion 14,
Since 11b has the slit 15 formed on the side surface of the case, it can be easily bent. Further, when removing the plastic case 11 from the metal cover 10, it is easier than the metal cover 10 by inserting a plate-shaped or wedge-shaped object between the metal cover 10 and the plastic case 11 and removing the projection 14 from the notch. Can be pulled out.

[Effect of device]

As described above, according to the present invention, the connector cover can be freely disassembled and reassembled, so that connection mistakes can be corrected, and when the shape, color, specifications, etc. of the plastic case are changed. Can also be supported.

[Brief description of drawings]

FIG. 1 is a diagram showing an embodiment of the present invention, FIG. 2 is a diagram for explaining the operation of the embodiment of the present invention, and FIG. 3 is a diagram showing a conventional connector cover including a metal cover and a plastic case. Is. In the figure, 10 is a metal cover, 11 is a plastic case, 12 and 12 'are engaging pieces, 13 is a notch, 14 is a protrusion, 15 is a slit, and 16 is a stopper.
