Description

Technical Field

[0001] This utility model belongs to the field of electronic technology, such as mobile phones, computers, electronic products, and automotive electronics. Specifically, it relates to a solderless shielding cover and terminal. Background Technology

[0002] With the advancement of technology, mobile phones are increasingly used in people's daily lives, and their production volume is also increasing. However, problems in both the use and production of mobile phones are becoming more and more prominent. Because mobile phone communication uses high-frequency electromagnetic waves, electromagnetic interference and electromagnetic shielding have become problems that must be solved in mobile phone production. The baseband radio frequency section of a mobile phone generates strong electromagnetic interference during calls. To shield against this interference, the industry practice is to weld a shielding cover onto it. Current technology uses integrated or separate shielding covers, but when it is necessary to inspect, repair, or replace internal parts, the shielding cover must first be desoldered. Desoldering may cause desoldering or damage to surrounding components, therefore, an improvement is necessary. Utility Model Content

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0040] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
