A conductive cover 100 of a mobile terminal according to an embodiment of the present invention is described below with reference to fig. 1 to 6.

As shown in fig. 1-6, the conductive cover 100 has opposing first and

second sidewalls

3 and 4 and a rear wall 5 connected between the first and

second sidewalls

3 and 4. For example, the rear wall 5 includes a pair of long sides and a pair of short sides parallel to each other, and the first side wall 3 and the second side wall 4 are provided on both long sides of the rear wall 5, respectively, or in other embodiments, the first side wall 3 and the second side wall 4 are provided on both short sides of the rear wall 5, respectively.

As shown in fig. 1-5, the conductive cover 100 further includes at least one set of a first slit tape set 1 and a second slit tape set 21. For example, as shown in fig. 1 and 3-6, the first band gap sets 1 are one set, or, in other embodiments, as shown in fig. 2, the first band gap sets 1 are two sets, with the two sets of first band gap sets 1 being spaced apart.

The first gap band set 1 is arranged partly on the rear wall 5, for example, with a part of the first gap band set 1 being located on the rear wall 5 and another part on the first side wall 3, or with a part of the first gap band set 1 being located on the rear wall 5 and another part on the second side wall 4, or with a part of the first gap band set 1 being located on the first side wall 3, another part on the rear wall 5 and still a part on the second side wall 4.

Each set of first slit tape groups 1 comprises at least one first slit tape 11, that is to say, the first slit tape groups 1 may comprise one first slit tape 11 and may also comprise a plurality of first slit tapes 11, the plurality of first slit tapes 11 being arranged at intervals when the first slit tape groups 1 comprise a plurality of first slit tapes 11. A first insulating spacer layer (not shown) is provided in each first slit tape 11.

In general, the all-conductive cover 100 (e.g., all-metal cover) has an effect of increasing the aesthetic appearance of the mobile terminal, but the all-conductive cover 100 (e.g., metal cover) has a signal shielding function, and cannot meet the design requirement of the antenna of the mobile terminal. Therefore, the first slot band set 1 is disposed on the conductive cover 100 of the mobile terminal, and the first slot band 11 is filled with a first insulating spacer layer (such as a non-conductive plastic material), where the first insulating spacer layer is a non-signal shielding material, so as to reduce the shielding effect on the antenna signal of the mobile terminal, thereby making the conductive cover 100 meet the design requirement of the antenna of the mobile terminal and improving the strength of the antenna signal of the mobile terminal.

Specifically, a second slit tape 21 is provided on at least one of the first side wall 3 and the second side wall 4, and a second insulating spacer layer (not shown) is provided in the second slit tape 21. For example, the first side wall 3 is provided with at least one second slit tape 21, the second side wall 4 is provided with at least one second slit tape 21, or the first side wall 3 and the second side wall 4 are respectively provided with at least one second slit tape 21.

According to the conductive cover body 100 of the mobile terminal provided by the embodiment of the invention, the first gap band group 1 and the second gap band 21 are arranged on the conductive cover body 100, the first gap band group 1 comprises at least one first gap band 11, the first gap band 11 is filled with the first insulating spacer layer, and the second gap band 21 is filled with the second insulating spacer layer, so that the design of the MIMO antenna of the mobile terminal is facilitated, the radiation performance of the antenna is improved, the signal intensity is optimized, the coverage of a conductive area of the conductive cover body 100 is ensured to the greatest extent, and the appearance of the conductive cover body 100 is optimized.

Preferably, the first slot band set 1 includes two first slot bands 11, as shown in fig. 1-2 and fig. 4-5, wherein one end of one first slot band 11a is located on the first sidewall 3 and the other end is located on the rear wall 5, and one end of the other first slot band 11b is located on the second sidewall 4 and the other end is located on the rear wall 5, thereby facilitating an increase in the length of the first slot band 11 and enhancing the radiation performance of the antenna. Preferably, as shown in fig. 1-2 and 4-5, one end of one first slot belt 11a is located on the first side wall 3 and penetrates through the first side wall 3 in the width direction of the first side wall 3, and the other end is located on the rear wall 5, and one end of the other first slot belt 11b is located on the second side wall 4 and penetrates through the second side wall 4 in the width direction of the second side wall 4, and the other end is located on the rear wall 5, so that one end of the first slot belt 11 formed has an opening, thus realizing a slotted antenna with an opening at one end, which is beneficial to improving the radiation performance of the antenna.

It can be understood that in each group of the first slot groups 1, the gaps between two adjacent first slot groups 11 can be set as required, so that the resonance of the antenna can be adjusted, and the performance index of the antenna can be improved.

In further embodiments of the invention, as shown in fig. 3 and 6, each set of first slit band groups 1 comprises a first slit band 11, the first slit band 11 comprising a first segment 111, a second segment 112 and a third segment 113 connected in sequence, wherein the first segment 111 is located on the first side wall 3, the second segment 112 is located on the rear wall 5 and the third segment 113 is located on the second side wall 4. In this way, the length of the first slot belt 11 is increased, the radiation performance of the antenna is improved, and the signal intensity of the mobile terminal is optimized.

Preferably, as shown in fig. 3, the first section 111 is disposed substantially perpendicular to the second section 112, and the second section 112 is disposed substantially perpendicular to the third section 113, which is advantageous not only for simplifying the structure of the first slit tape 11, but also for increasing the aesthetic appearance of the conductive cover 100. Specifically, the first section 111, the second section 112, and the third section 113 are all straight sections, however, the present invention is not limited thereto, and in other embodiments, the first section 111, the second section 112, and the third section 113 may be curved, zigzag, or wavy.

In some embodiments of the present invention, as shown in fig. 6, the width of the first slit tape 11 is d1, d1 satisfies: d1 is more than or equal to 0.5mm and less than or equal to 2mm. For example, d1 is 0.6mm, 0.7mm, 0.8mm, 1.2mm, 1.5mm, 1.8mm, or the like. The first gap band 111 can be filled with the first insulating spacer layer, so that the shielding effect on the antenna signal of the mobile terminal can be reduced, the conductive cover body 100 can meet the design requirement of the antenna of the mobile terminal, the attention of a user is not easy to draw, the integrity of the conductive cover body 100 can be ensured, the seamless effect is achieved in appearance, and the aesthetic property of the conductive cover body 100 is improved.

This can further ensure the integrity of the conductive cover 100, further achieve a seamless effect in appearance, and enhance the aesthetic appearance of the conductive cover 100. For example, in the example shown in fig. 1-5, the first slit tape 11 includes three first micro slits 114 arranged at intervals, and the first micro slits 114 may be filled with a first insulating spacer layer. Alternatively, the metal strip 115 may be integrally formed with the conductive cover 100.

Further, the width of the first micro slit 114 is d2, and d2 satisfies: d2.ltoreq.0.5 mm, for example, the width of the first micro slit 114 is 0.13mm, 0.2mm, 0.3mm, 0.36mm or the like. Therefore, the shielding effect on the antenna signal of the mobile terminal can be reduced, so that the conductive cover body 100 meets the design requirement of the antenna of the mobile terminal, the attention of a user is not easily drawn, the integrity of the conductive cover body 100 can be ensured, the seamless effect is achieved in appearance, and the attractiveness of the conductive cover body 100 is improved. It is understood that the width of each first micro slit 114 may be the same or may be different.

second sidewalls

Thus, it can be understood that when the number of the second slot belts 21 is plural, the plural second slot belts 21 may simultaneously realize one antenna function, and of course, the plural second slot belts 21 may also respectively realize different antenna functions. Preferably, the second slot strip 21 may be used to implement a MIMO antenna with a frequency band of 2.4G or 3.5G.

Specifically, the plurality of second slit tapes 21 on the first side wall 3 and the plurality of second slit tapes 21 on the second side wall 4 are symmetrically disposed with respect to the center line of the rear wall 5.
