Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.

Unless otherwise specified, use of the terms of orientation such as "upper, lower, left, right" are defined according to the directions indicated in the respective drawings, and "inner" and "outer" refer to the inner and outer of the contours of the respective parts themselves. Furthermore, the terms "first," "second," and the like, as used herein, are intended to distinguish one element from another, and are not necessarily order or importance.

As shown in fig. 1 and 2, the present disclosure provides a motherboard assembly including a motherboard 1, an electronic component 2 disposed on the motherboard 1, and a first shield case 3 covering the outside of the electronic component 2. Depending on the function to be achieved, a plurality of different electronic components 2 may be disposed on the motherboard assembly, and the first shielding cage 3 may be selectively disposed on at least a portion of the electronic components 2. The first shield shell 3 includes a first frame 31 and a first shield 32 connected to the first frame 31, and the first frame 31 and the first shield 32 are integrally formed. The first frame 31 may be fixed to the motherboard 1 by welding or bonding, the first shielding member 32 is a main component for shielding electromagnetic radiation, and in the embodiment shown in fig. 1, the first shielding member 32 is configured as a hood shape as a whole and covers the outside of the electronic component 2.

A pre-cut portion 33 is formed at a junction of the first frame 31 and the first shield 32, and the pre-cut portion 33 has a closed profile such that the first shield 32 is removed from the first frame 31 along the pre-cut portion 33. The precut portion 33 is a portion which is easily cut and is formed at the joint of the first frame 31 and the first shield member 32 by a specific structure or a specific method in the process of molding the first shield shell 3. The presence of the pre-cut portion 33 allows the first rim 31 and the first shield 32 to remain structurally connected, but is more fragile relative to the first rim 31 and the first shield 32 themselves so as to be easily cut when needed. The pre-cut 33 has a closed profile so that the first shield 32 can be removed intact.

Through the technical scheme, namely the pre-breaking part 33 is arranged at the joint of the first frame 31 and the first shielding piece 32, the pre-breaking part 33 has a closed outline, so that the first shielding piece 32 can be easily removed from the first frame 31 along the pre-breaking part 33 to expose the electronic element 2 covered by the first shielding piece 32, and therefore the electronic element is maintained without damaging the first frame 31, the operation is simple, and the cost is saved. The first rim 31, which is left intact, can also be used for a detachable co-operation with the cover 5, which will be described in detail later and will not be described in detail here.

The present disclosure is not limited to the specific structure and forming manner of the pre-cut portion 33, and any structure or method capable of achieving the cutting-off to remove the first shield 32 can be applied to the present disclosure. As shown in fig. 1, the pre-cut portion 33 may be a linear indentation formed at the junction according to an embodiment of the present disclosure. For example, during the manufacturing process of the first shield can 3, an indentation may be formed at the joint by stamping or the like, the indentation makes the thickness of the joint thinner relative to the first frame 31 and the first shield 32, so as to be cut off more easily, and the linear indentation can also provide a cutting track, i.e., guide a cutting tool to cut along the extending path of the pre-cut portion 33, so as to completely remove the first shield 32. In other embodiments, pre-break 33 may also be used with a perforation line such as is common in postage stamp unions.

Fig. 1 and 2 show a rectangular profile formed with linear indentations, the first shield can 3 comprises a first opening 311, the first shield 32 is covered at the first opening 311, and at least one corner and/or side of the first opening 311 is provided with a removal hole. That is, the detachment hole may be provided at a corner of the first opening 311, or provided at a side of the first opening 311, or provided at both the corner and the side of the first opening 311. The presence of the removal hole makes it easier for the first shield 32 to be cut.

In some embodiments, the removal aperture may include a first aperture 34, wherein the first aperture 34 is located at a corner of the first opening 311. In the embodiment shown in fig. 1 and 2, the first apertures 34 are four in number and are L-shaped holes provided at four corners of the pre-breaking portion 33, respectively. When the cutting tool is used for cutting the pre-breaking part 33, the cutting tool cannot be flexibly used at the corner of the rectangular outline due to the narrow operable space, and the L-shaped first opening hole 34 is formed in the corner, so that the cutting tool does not need to cut at the corner, and the working efficiency is improved.

In the process of cutting, for example, a linear indentation, since the first opening 311 has a longer operating distance at each side, for high operating efficiency, the dismounting hole may further include a second opening 35, the second opening 35 being located at the side of the first opening 311, and in particular, the second opening 35 being located at a position of the pre-cut portion 33 between any adjacent two of the first openings 34. As shown in fig. 1 and 2, the second apertures 35 are configured as circular holes. In this way, an effect similar to the stepwise cutting can be achieved, and the difficulty of operation is reduced with respect to cutting the entire precut section 33 at one time.

As shown in fig. 3 and 4, the main board assembly provided by the present disclosure includes, in addition to the first shielding case 3, a second shielding case 4 disposed outside the other electronic component(s) 10. The second shielding can 4 includes a second frame 41 and a second shielding member, wherein the second frame 41 may have the same configuration as the first frame 31, for example, the second frame 41 has a second opening 411, and the second opening 411 can expose another electronic component 10 inside. Different from the first shielding case 3, the second shielding member is a plurality of connecting ribs 42 disposed inside the second opening 411, and the width of the joint of the connecting ribs 42 and the joint of the connecting rib 42 and the second frame 41 is smaller than the width of the main body of the connecting rib 42.

The connecting ribs 42 have a function similar to that of reinforcing ribs, and improve the overall strength of the second frame 41, and improve the deformation resistance of the second frame 41 when the other electronic component 10 is not replaced. The width of the joint of the connecting ribs 42 and the joint of the connecting rib 42 and the second frame 41 is smaller than the width of the main body of the connecting rib 42, in other words, the narrow edge design is performed at the position where the connecting rib 42 needs to be cut off, and the connection strength of the joint of the connecting rib 42 is weakened, so that the cutting off is easier.

As an embodiment that the width of the joint of the connecting ribs 42 and the joint of the connecting rib 42 and the second frame 41 is smaller than the width of the main portion of the connecting rib 42, with reference to fig. 3 and 4, a slot 43 is formed at the joint of the connecting ribs 42 and the joint of the connecting rib 42 and the second frame 41 and extends from the connecting rib 42. In the embodiment shown in fig. 3, two slots 43 are provided to extend inward from both sides of the connecting rib 42 in the width direction. The slot 43 may be configured as a rounded slot to reduce stress concentrations. In addition, the plurality of connection ribs 42 may be connected in one place to serve as a suction cup of the shield case.

According to an embodiment of the present disclosure, as shown in fig. 5 and 6, the main board assembly may further include a cover 5 for detachably covering the first bezel 31 and/or the second bezel 41. That is, the cover 5 may be provided on each of the first frame 31 and the second frame 41, or the cover 5 may be provided on each of the first frame 31 and the second frame 41. When the shield is removed, the first frame 31 and the second frame 41 are not damaged, and therefore, the shield can be used to cooperate with the enclosure 5, and specifically, the enclosure 5 can be detachably mounted on the first frame 31 and the second frame 41. The presence of the enclosure 5 enables the shield to still fulfil the function of shielding electromagnetic radiation.

To achieve the detachable attachment between the cover 5 and the rim, with continued reference to fig. 5 and 6, the peripheral edge of the cover 5 is bent to form a flange 52, and the flange 52 has an elastic force capable of elastically abutting against the outer side wall of the first rim 31 and/or the second rim 41 after the attachment. In the image, the cover 5 is configured in a box shape, and during the process of installing the cover 5, the flange 52 is gradually pushed outwards along with the buckling of the cover 5 until the flange 52 is firmly abutted on the outer side walls of the first frame 31 and the second frame 41 under the action of the elastic restoring force after the cover 5 is installed in place. When the cover is removed, the cover body 5 is pulled out upwards only by force. Optionally, the cover body 5 is provided with a notch 51 at a corner, and the design with the notch 51 enables the flange 52 to obtain larger elastic deformation, so that the cover body is suitable for frames with more size ranges, and the universality is improved.

A second object of the present disclosure is to provide a terminal device, as shown in fig. 7, the terminal device includes a motherboard assembly and a middle frame 6, the motherboard assembly is the motherboard assembly of any one of the above embodiments, a copper sheet 7 is welded on the middle frame 6, and the motherboard 1 is connected with the copper sheet 7 through an antenna elastic sheet 8. Fig. 8 shows a terminal device provided for the related art, in a general copper sheet welding scheme, welding points are distributed in an L shape on the whole, however, this welding scheme needs to occupy more space in the Z direction (the thickness direction of the terminal, i.e. the up-down direction in fig. 7 and 8), which results in that the space in the Z direction of the terminal device cannot be fully utilized, especially for the design of the whole machine opening 9 such as a microphone hole, a speaker hole and a SIM card hole.

To solve the above problem, as shown in fig. 7, the present disclosure configures the solder joints of the copper sheet 7 to include two rows spaced apart in the thickness direction of the terminal device and each row includes a plurality of solder joints 71 spaced apart in the width direction or the length direction (left-right direction in fig. 7). That is, the plurality of pads 71 as a whole appear to be formed in a "two" shape. The design realizes the conversion of the Z-direction space into the X-direction (the terminal width direction or the terminal length direction), thereby fully utilizing the Z-direction space of the terminal equipment.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.
