Description

EMI shielding cover

Technical Field

The utility model relates to an electronic product field especially relates to small-size electronic product's EMI protection field, specifically indicates an EMI shield cover.

Background

Devices in electronic products generally can be subjected to electromagnetic interference, therefore, the electronic devices need to be protected against EMI (electromagnetic interference), a shielding cover is often adopted in the prior art to realize electromagnetic interference resistance, however, in the actual operation process, the devices in the electronic products are sometimes damaged, but if a fixed shielding cover in the prior art is adopted, the problem of inconvenient disassembly and maintenance can occur, and a protective cover convenient to disassemble is also adopted in the prior art in the actual operation, and if the electronic products fall or are transported, the corresponding shielding cover is easy to fall off, so that the protective effect of the electromagnetic interference is lost. The shielding cover in the prior art often can not compromise the problem of firm and easy dismantlement.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming at least one above-mentioned prior art's shortcoming, providing a simple structure, excellent in use effect's EMI shield cover.

To achieve the above and other objects, the EMI shield of the present invention is as follows:

the EMI shielding cover is arranged on an electronic component and is mainly characterized in that the EMI shielding cover comprises an upper shell and a lower shell which are connected in a clamping mode, and the electronic component is arranged in a space formed by clamping the upper shell and the lower shell.

Preferably, the upper shell is provided with a clamping hole, the lower shell is provided with a buckle corresponding to the clamping hole in size, shape and quantity, and the clamping connection between the upper shell and the lower shell is realized through the clamping hole and the buckle.

Preferably, the buckle is a sheet structure having a predetermined included angle with the wall surface of the lower housing, and is inclined toward the upper housing.

Furthermore, the buckle is a sheet structure which is formed by punching and shearing the wall surface of the lower shell and forms a preset included angle with the wall surface of the lower shell, and one side of the sheet structure is connected with the wall surface of the lower shell.

Preferably, the buckle is a square boss, and the clamping hole is a square opening.

This EMI shield cover includes last casing and lower casing of connecting through the block mode, arrange electronic components in by last casing and lower casing block in the space that forms behind, convenient to detach's block structure can carry out the electromagnetic interference protection to electronic components in order to guarantee EMI shield cover, simultaneously, can compromise the fastness and the easy disassembly nature of connection, realizes avoiding transporting or falling the droing under the condition to can demolish last casing fast when needs are repaired electronic components, ensure the portability of repair in-process. Adopt the utility model discloses an EMI shield cover through simple and convenient structural design, just can effectively carry out the electromagnetic interference protection, possesses the equipment convenience, and anti-drop, processing is simple, low cost's characteristics.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is described in detail with reference to specific embodiments.

As shown in fig. 1 to 5, the EMI shielding case of the present invention includes an upper housing and a lower housing connected by a snap-fit manner, and a space for placing electronic components is formed after the upper housing and the lower housing are snapped together.

In this embodiment, the upper housing is provided with a fastening hole, the lower housing is provided with a fastener corresponding to the size, shape and number of the fastening hole, and the fastening connection between the upper housing and the lower housing is realized through the fastening hole and the fastener, wherein the upper housing is located at the upper part in fig. 1, and the lower housing is located at the lower part.

In this embodiment, the fastener is a square boss, and the fastening hole is a square opening.

In this embodiment, the buckle is a sheet structure having a predetermined included angle with the wall surface of the lower housing, and is inclined toward the upper housing.

In this embodiment, the degree of the preset included angle is about 20 degrees, and in the process of other embodiments, the degree of the included angle can be adjusted according to different product requirements, and the tightness of the clamping can be changed through the adjustment of the angle.

The buckle structure in the EMI shielding case in the embodiment can be used for connecting a small metal part with a thinner wall thickness, and the shielding case adopting the buckle structure can realize shielding of specific electronic components of 3C electronic products.

In this embodiment, the buckle is a sheet structure which is formed by punching and shearing the wall surface of the lower shell and forms a preset included angle with the wall surface of the lower shell, and one side of the sheet structure is connected with the wall surface of the lower shell.

In this embodiment, the buckle is boss structure, and this structure adopts to dash and cuts even limit and constitutes, and the inclination of this boss can be properly adjusted as required's block dynamics when production, and the square hole cooperation on this boss structure and the last casing effectively avoids falling or the transportation lower casing risk of droing.

As shown in fig. 3 and 4, after the upper and lower housings are engaged, a portion of the latch extends beyond the latch hole, and in this embodiment, two pairs of latches and latch holes are provided on each side of the EMI shield. It can be seen from fig. 5 that the snap fits well into the snap hole, and for a better description of the snap and snap hole in this embodiment, in fig. 6, which shows the cross-sectional configuration of the plane a-a in fig. 5, it can be seen that the catch is a tab-like structure integral with the lower housing at an angle, in the clamping state, the buckle can ensure the connection between the upper shell and the lower shell through the clamping hole, the specific structure of the structure can be more obviously seen from the detail drawing in figure 7, if the user will go up the casing when taking off from casing down, only need inwards push away this buckle, just can be convenient take off last casing from casing down, be convenient for carry out the components and parts maintenance, in addition, go up the casing and can not drop from casing down because of falling or the external force of transportation, realized compromising and turning over the effect of dismantling and preventing unexpected the drop.

The EMI shielding cover can be used for EMI (Electromagnetic Interference) protection of small electronic products and can also be used as box type products of a clamping structure of a small upper iron shell and a small lower iron shell.

In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
