Description
Technical field
Mobile terminal preparation field is the utility model is related to, in particular it relates to housing unit and mobile terminal.
Background technology
With the fast development of the electronic products such as mobile phone, tablet personal computer, notebook computer, each electronic product layer goes out
It is not poor.Therefore, people propose higher requirement to the various aspects of the mobile terminals such as electronic product, particularly mobile phone.Remove
Beyond the performance of electronic product, user it is also proposed higher requirement for the outward appearance of electronic product.Metal shell due to
With texture more attractive in appearance, it is applied to by more and more extensive in each class of electronic devices.And due to the metal shell meeting of flood
Form shielding and hinder mobile communication, therefore, it is necessary in the housing that metal is formed, nonmetallic day line piece is set.
However, the current housing unit and mobile terminal based on metal, still has much room for improvement.
Utility model content
The utility model is the following discovery based on inventor and completed：
The all-metal housing of the mobile terminal such as mobile phone at present, generally existing are needed to set day linear slit, and appearance is not enough united
One, and the problems such as metal shell intensity is bad.Inventor has found that this is mainly due to mesh by further investigation and many experiments
Preceding day line piece is generally arranged on inside handset shell, therefore when preparing handset shell using metal, it is necessary to using " three sections
Formula " structure, the opening position of line piece in day, form the day linear slit that can pass signals through housing.I.e. in handset shell, one is prepared
Individual or multiple slits through metal shell, megohmite insulant is filled at slit, so that the metal above and below slit can use
Megohmite insulant (plastic cement etc.) cut-off is opened, and is formed and is prohibited dummy section.However, realizing thus needs first to process antenna partition grooves, so
Filled afterwards with plastic cement.But this processing mode can not only influence product appearance integrality, while increase process time.Also,
Prohibit dummy section and will also result in the overall mechanical performance decline of metal shell.In addition, if so that metal shell multifunction, then
Be advantageous to further save the internal volume of mobile terminal so that mobile terminal slimming.
The utility model is intended to one of technical problem at least solving in correlation technique to a certain extent.Therefore, this reality
It is to propose a kind of housing for avoiding preparing penetration type slit with a new purpose, and by the way that day line piece is arranged on into housing
Upper formation housing unit, realizes the communication of mobile terminal.
In one side of the present utility model, the utility model provides a kind of housing unit.The housing includes：Matrix,
Described matrix is formed by metal；Baltimore groove, the Baltimore groove are set on the matrix, and the spill trench bottom has extremely
A few connecting hole for running through described matrix；And day line piece, the day line piece insulation set is in the Baltimore groove, with radiation
Aerial signal.Thus, it is possible to which day line piece to be arranged on to the outside of housing, and pass through the structure inside connecting hole, with mobile terminal
It is connected, realizes the function of antenna.Also, only there is the connecting hole of a small amount of penetrability in the housing unit, thereby may be ensured that gold
Belong to the overall mechanical properties of housing.Generally speaking, the housing unit has that processing technology is simple, appearance is unified, machinery is strong
Degree is strong, can save at least one of the advantages that mobile terminal inner space using the housing unit.
In another aspect of the present utility model, the utility model proposes a kind of mobile terminal.Before the mobile terminal includes
Housing unit described in face.
