Embodiment Construction
[0018] The invention provides a shell combination device of a mobile communication terminal. The present invention will be described in more detail below with reference to the accompanying drawings.
[0019] image 3 It is an exploded oblique view of the mobile communication terminal adopting the shell combining device of the present invention; Figure 4a and Figure 4b yes image 3 Sectional views of line II-II and line III-III.
[0020] The housing coupling device of the mobile communication terminal of the present invention is composed of a hook 29 and a hook groove 27, and the hook 29 and the hook groove 27 are correspondingly formed on the side walls of the upper housing 21 and the lower housing 23, wherein the upper housing 21 and the lower housing 23 The lower shells 23 are combined with each other to define an internal space 25 for fittings such as a PCB (not shown) or a keypad (not shown).
[0021] The hook groove 27 is formed on the side wall of the lower housin...

The present invention discloses a casing combining device of mobile communication terminal which belongs to mobile communication terminal. This device includes: hook groove, which lies on the lateral wall of the outer shell lower part and shows convex along the length direction; hook, which lies on the lateral wall of the outer shell upper part corresponding to the hook groove and prolongs to the direction of outer shell lower part, and to insert into the hook groove. Thus, due to the hook and hook groove form on the lateral wall of the outer shell upper and lower part without projecting to the inner space, the structure of the built-in PCB or keypad in the inner space and the machining for them is simple, also the size of the outer shell combined can be prevented from increasing.
Description
technical field [0001] The invention belongs to the scope of components of mobile communication terminals, and in particular relates to a casing combination device of a mobile communication terminal. Background technique [0002] According to the appearance and structure, mobile communication terminals are roughly divided into bar type, cover type, flip type and slide type. [0003] The bar type and cover type mentioned above are the initial configurations of mobile communication terminals, and they are long and inconvenient to carry. Therefore, mobile communication terminals such as flip-type and slide-type were developed later. This structure is composed of two shells, that is, an upper flip and a lower flip. The upper and lower flips of the straight type and cover type terminal body, and the flip type and slide type have built-in printed circuit board (PCB) or keypad and other accessories in the inner space between the upper case and the lower case, respectively. . The...
