Description

Isolation cover

technical field

The utility model relates to a metal plate isolation cover composed of an upper cover and a shielding frame, especially to provide a kind of tearing and dismantling action of the upper cover that is easier to do without causing the shielding frame to be twisted. , Improved isolation cover for deformers.

Background technique

According to the current existing metal plate isolation cover 2 dedicated to covering the outside of the chip 4 on the circuit board 3 of an electronic or computer product to prevent electromagnetic wave interference, it is shown in Fig. 8, Fig. 9 and Fig. 10 in detail. (i.e. the content disclosed in Taiwan Patent Announcement No. 00506692 or U.S. Patent No. 6,178,097B1), by stamping, a notch is punched around the upper wall 20 of an isolation cover 2 near the outer edge. (Score line) 211a, 211b, 211c and 211d, make this metal isolating cover 2 form and be formed by combining a loam cake 21 and a shielding frame 22; , at least each is provided with a plurality of bridging portions 23; the loam cake 21 and the shielding frame 22 are prevented from breaking away; Pry open the upper cover 21 as shown in FIG. 10 to tear and remove the upper cover 21 .

After the existing metal isolation cover 2 covers the outside of the chip 4 on the circuit board 3 of an electronic or computer product (that is, the state shown in Figure 9 and Figure 10), it can certainly be inserted into it with a tool 5 as described above. In the holes 212 on each corner of the upper cover 21, after the action of prying open (that is, the state shown in Figure 10), the upper cover 21 can be torn off and removed, leaving only its shielding frame 22 covered on the On the periphery of the chip 4, the effect of shielding electromagnetic waves is achieved. But, because the notches 211a, 211b, 211c and 211d positions set around the upper wall 20 of the metal isolation cover 2 are at least the easily tearable (fragile) connecting portion 213 ( As shown in Figure 9 and Figure 10); meanwhile, on each side of the notches 211a, 211b, 211c and 211d, a plurality of bridging portions 23 are separately set up to connect the upper cover 21 and the shielding frame 22. Therefore the upper cover 21 and the shielding frame 22 of this existing metal isolation cover 2 are connected quite firmly, so it is not easy to do the aforementioned action of tearing and removing the upper cover 21---that is, very strenuous; When the upper cover 21 is removed, the shielding frame 22 is likely to be twisted and deformed, which will affect the appearance of the chip 4 or cause it to be unable to fit tightly on the chip 4 .

Detailed ways

As shown in Figure 1, the metal improved isolation cover 1 of the present utility model is the same as the aforementioned existing structure, mainly by stamping at a position close to the outer edge of its upper wall 10 to set a score (Score line) 111a, 111b, 111c and 111d, so that the improved isolation cover 1 is formed by combining an upper cover 11 and a shielding frame 12; Hole 112. In addition, the improved isolation cover 1 of the present utility model is improved on the above-mentioned notches 111a, 111b, 111c and 111d on each side, and a plurality of sections of easy-to-break (fragile) connecting parts 113 are respectively arranged continuously (see details in detail). 3) and a completely broken separation part 114 (as shown in FIG. 4 in detail).

Since the improved isolation cover 1 of the present utility model is as mentioned above, on the outer periphery of its upper cover 11 and on each side score 111a, 11b, 111c and 111d between the shielding frame 12, there are many completely broken separation parts between them. 114, so at least half of the bonding portion and bonding force between the upper cover 11 and the shielding frame 12 can be reduced; therefore, when a tool 5 is inserted into any corner position hole of the upper cover 11 as shown in Figure 1 In 112, the action of prying and opening loam cake 11 (the same state as shown in Figure 10) can be easily done, and the action of tearing and removing this loam cake 11 (that is, the state shown in Figure 5) can be easily done.

Please refer to FIG. 6 again, which is a perspective view of an improved metal isolation cover 1a of another preferred embodiment of the present invention. The main structure of the improved isolation cover 1a of this preferred embodiment is the same as that of the improved isolation cover 1 implemented above, except that the edge notches 111a, 111b, 111c and 111d at the corners of the upper cover 11 are improved. One or several sections of easily breakable (fragile) connection parts 113 are provided respectively, and the remaining parts of the notches 111a, 111b, 111c and 111d on each side are all set as completely broken separation parts 114. In the same way, the improved isolation cover 1a of this preferred embodiment can be further divided into the notches 111a, 111b, 111c and 111d on the sides of the corners of the upper cover 11, and one section or several sections that are easy to break are respectively provided. In addition to the (fragile) connecting portion 113, one or more easily broken (fragile) connecting portions 113 are respectively set at the center of the notch 111a, 111b, 111c or 111d on each side, and each side notch 111a , 111b, 111c and the rest of 111d are all set as completely broken separation parts 114 .

Because of the aforementioned preferred embodiment of the utility model, on each side of the notch 111a, 111b, 111c or 111d of the improved isolation cover 1a, there are only a few sections of easy-to-break (fragile) connecting parts 113, most of which are completely broken. Separation portion 114, so the bonding portion and bonding force between the outer periphery of its loam cake 11 and the shielding frame 12 are more limited; (or on any side) in the hole 112, the action of prying off the upper cover 11 (the same state as shown in Figure 10) can be done more easily, and the action of tearing and removing the upper cover 11 can be done more easily ( That is, the state shown in Figure 7).
