In some embodiments, the conductive housing includes a closed conductive bezel.

That is to say, compared with the monopole antenna or the dipole antenna that needs to set a breakpoint in the conductive frame to implement the antenna function, the embodiment of the present disclosure does not need to set a breakpoint in the conductive frame when the conductive frame is used as a radiator, so that the radiation bandwidth can be increased, the influence of environmental factors on radiation of wireless signals can be reduced, and the communication quality can be improved; the nano injection molding process required by setting the breakpoint can be reduced, so that the conductive frame is simpler to manufacture; meanwhile, the condition that the conductive frame is easy to deform due to the fact that the breakpoint is arranged can be reduced, and the stability of the conductive frame is improved.

Wherein, the bonding pad adopting the DIP process is provided with a welding hole; the bonding pad adopting the SMI process can be a bonding pad formed in a metal exposed area in a printed circuit board and used for mounting a component on the surface of the metal exposed area.

Note that the area of the connection portion of the conductive sheet to which the pad is connected is smaller than or equal to the area of the pad. And the area of the connection portion is positively correlated with the area of the bonding pad. For example, the area of the pad corresponding to a larger area of the connection portion is larger than the area of the pad corresponding to a smaller area of the connection portion.

Illustratively, the area of the pad may be set to 0.8 mm square or 0.9 mm square.

In the embodiment of the present disclosure, the connection mode of the conductive sheet and the conductive shell includes: the conducting strip is connected with the conducting shell in a contact mode or indirectly.

It should be noted that the indirect connection between the conductive sheet and the conductive housing includes: the conducting plate and the conducting shell are connected through the fixing module. The fixed module has a conductive function and also has a bonding function of bonding a conductive sheet and a conductive shell.

Illustratively, the fixing module includes, but is not limited to, a conductive adhesive.

That is, the conductive sheet of the embodiment of the present disclosure may be connected in a proximity manner, where the distance between the conductive housing and the pad is the shortest.

In some embodiments, the conductive housing comprises: a conductive bezel; the conductive frame is provided with a first frame and a second frame adjacent to the first frame; the first frame and the second frame are distributed towards different surfaces of the printed circuit board, and the distance between the first frame and the pad is smaller than the distance between the second frame and the pad; the conducting strip is connected with the first frame.

That is to say, when connecting adjacent conductive frame, the conducting strip adopts the mode of connecting nearby, connects the conductive frame that is nearest, so, can reduce the length of conducting strip.

In other embodiments, the conductive bezel further has a third bezel parallel to the first bezel and adjacent to the second bezel; the distance between the first frame and the bonding pad is smaller than the distance between the third frame and the bonding pad; the conducting strip is connected with the first frame.

That is to say, when the opposite and parallel conductive frames are connected, the conductive sheets are also connected in a nearby connection manner, and the conductive frame closest to the conductive sheets is connected, so that the length of the conductive sheets can be reduced.

In other embodiments, the conductive housing comprises: a conductive backshell;

That is to say, when connecting electrically conductive dorsal scale, what the conducting strip adopted is also the mode of connection nearby, and the lug connection is in the region at projection position place, and then also can reduce the length of conducting strip.

Illustratively, the conductive sheet may be formed of a metal or alloy material. Wherein the metal includes, but is not limited to, cupronickel or brass.

In the embodiment of the present disclosure, the pad, the conductive sheet, and the conductive housing form a radiator of the antenna. The radiator of the antenna may be a radiator of a Bluetooth (BT) antenna, may also be a radiator of a wireless fidelity (WIFI) antenna, may also be a radiator of a Universal Mobile Telecommunications System (UMTS) antenna, and may also be a radiator of a Long Term Evolution (LTE) antenna.

It should be noted that, when the radiator of the antenna is a radiator of a BT antenna, the radiator of the antenna may be used to receive and transmit a 2.4GHz wireless signal; when the radiator of the antenna is the radiator of the WIFI antenna, the radiator of the antenna can be used for receiving and transmitting wireless signals with the frequency of 2.4GHz and 5 GHz. When the radiator of the antenna is the radiator of the LTE antenna, the radiator of the antenna can be used for receiving and transmitting wireless signals in a frequency band from 2635MHz to 2675MHz or a frequency band from 4800MHz to 4900 MHz.

In the embodiment of the disclosure, the area of the radiator can be increased, and the radiation efficiency and the radiation bandwidth can be improved by the radiator of the antenna formed by the bonding pad, the conductive sheet and the conductive frame. Wherein, the radiation bandwidth is the ratio between the highest radiation efficiency of the radiator and the lowest radiation efficiency of the radiator.

Illustratively, the radiation bandwidth of the radiator of the antenna may be greater than or equal to 1.5.

In the related art, as shown in fig. 2, in a red frame is an on-board antenna. The on-board antenna is a meander line or a serpentine line, and the on-board antenna may be a BT antenna. As shown in fig. 3, the radiation efficiency of the on-board antenna was verified to be 54% by simulation. As shown in fig. 4, the standing wave ratio of the on-board antenna exceeds 3, further illustrating the low practical radiation efficiency of the on-board antenna.

Based on this, the embodiments of the present disclosure provide that the pad, the conductive sheet, and the conductive housing form an antenna radiator, which is commonly used for transceiving wireless signals. That is, the electrical signals on the printed circuit board can be directly guided to the conductive housing through the pads and the conductive sheet. On the one hand, the area of the radiator can be increased, and the radiation efficiency and the radiation bandwidth are improved. On the other hand, when the wireless signal is radiated, the conducting strip bears part of the electric signal, the electric signal borne by the conducting shell can be reduced, the condition that the electric signal in the conducting shell is exposed can be further reduced, and the radiation efficiency of the radiator of the antenna is further improved.

As shown in fig. 5, it is verified by simulation that the radiation efficiency of the radiator of the antenna of the embodiment of the present disclosure is as high as 94%. It can be seen that the radiation efficiency is greatly improved compared to an on-board antenna. As shown in fig. 6, in the frequency band from 2GHz to 3GHz, the standing wave ratio of the radiator of the embodiment of the present disclosure is not more than 3, and it can be further illustrated that the radiation efficiency of the radiator of the antenna of the embodiment of the present disclosure is high.

In some embodiments, as shown in fig. 7 and 8, the conductive sheet 104 comprises: a planar region 104a and an arc region 104b adjacent to the planar region 104 a;

the planar region 104a is connected with the pad;

the arc-shaped area 104b is connected to the conductive housing, and the arc-shaped area 104b is suspended between the conductive housing and the printed circuit board.

For example, as shown in fig. 7, the radius of the arc region may be 8 mm, the distance between the center of the arc region and the suspended edge of the arc region may be 2 mm, and the length of the flat region may be 10 mm. As shown in fig. 8, the thickness of the conductive sheet may be between 0.2 and 0.3 mm.

In the embodiment of the disclosure, the conductive sheet can be connected with the pad by welding.

The plane area of the conducting plate is provided with a gap with the printed circuit board or the conducting plate and the plane area are separated by an insulating material. Therefore, the conducting plate can reduce the interference between the conducting plate and the printed circuit board when radiating wireless signals.

The planar area of the conductive sheet may be parallel to the printed circuit board. Therefore, the layout of each device in the terminal equipment can be more regular.

It should be noted that the conductive housing includes a conductive bezel; the printed circuit board is positioned in the conductive frame, and a gap is formed between the printed circuit board and the conductive frame. In some embodiments, the length of the planar region of the conductive sheet is positively correlated to the shortest distance between the pad and the edge of the printed circuit board. For example, when the shortest distance between the pad and the edge of the printed circuit board is 8 mm, the length of the planar area of the conductive sheet may be set to 10 mm; when the shortest distance between the pad and the edge of the printed circuit board is 9 mm, the length of the planar region of the conductive sheet may be set to 11 mm, and the embodiments of the present disclosure are not limited.

In other embodiments, the projection width of the conductive sheet projected onto the printed circuit board is positively correlated to the gap. For example, when the projected width is 2 mm, the width of the gap may also be 2 mm. When the projected width is 1.5 mm, the width of the gap may also be 1.5 mm, and the disclosed embodiments are not limited.

In the disclosed embodiment, the arc-shaped area is suspended between the conductive shell and the printed circuit board. That is, the connection of the arc-shaped area and the conductive shell is a contact connection.

The arc-shaped area comprises a first end and a second end, the first end is connected with the plane area, and the second end is suspended. The second end portion is suspended, so that the second end portion is suspended in an area between the printed circuit board and the conductive shell, and the second end portion is not supported by the connecting module or the supporting module.

It should be noted that the conductive sheet may be a metal sheet, and the conductive sheet itself has certain elasticity and ductility. Therefore, even though the second end of the arc-shaped area is suspended, the suspended second end is extruded by the conductive shell, and the conductive shell can be stably connected with the second end through the recovery of the elastic deformation of the suspended second end.

In the embodiment of the present disclosure, the opening of the recess of the arc region faces away from the direction in which the conductive housing is connected to the second end portion. It should be noted that, the conductive frame of the conductive housing is generally a frame with a certain radian, and is connected with the conductive frame through the arc-shaped area, so that the area of contact connection can be increased, and the contact connection is more reliable.

It can be understood that the conducting strips of the embodiments of the present disclosure are no longer in a fixed sheet shape, but are set to be in different shapes according to different connection objects, so that the conducting strips can be reliably connected with the pad and the conducting shell, and the connection reliability is improved.

In some embodiments, as shown in fig. 9, the pad comprises at least one solder hole;

portions of the conductive strips 104 are inserted into and welded within the weld holes;

alternatively, the first and second electrodes may be,

the edge of the conductive sheet 104 has a pin 104c, and the pin 104c is welded in the welding hole. The middle plane area of the conducting plate is connected with the bonding pad, and the edge of the plane area is provided with a pin.

It should be noted that the number of the leads may be equal to the number of the solder holes. For example, when the number of the leads is 1, the number of the solder holes is also 1; when the number of the pins is 2, the number of the soldering holes is also 2.

In the embodiment of the disclosure, when the number of the pins is two or more, different pins are welded in the corresponding welding holes.

It should be noted that the included angle between the pin and the planar area may be 90 degrees, so that the pin may be vertically inserted into the solder hole, and stable connection between the pin and the pad is achieved. Or, the part of the conducting strip inserted into the welding hole can be vertical to the printed circuit board, and the stable connection of the conducting strip and the welding disc can also be realized.

It can be understood that the pins arranged at the edge of the conducting strip are welded in the welding holes; or the conducting strip part is inserted and welded in the welding hole, so that the connection reliability of the conducting strip and the welding disc can be improved.

In some embodiments, as shown in fig. 10 and 11, the conductive housing 101 has a card slot 101a thereon;

at least part of the conducting strip is embedded into the clamping groove.

As shown in fig. 10, the conductive housing is an arc-shaped conductive housing. As shown in fig. 11, the conductive housing 101 includes a conductive inner wall 101c and a conductive outer wall 101b, and the card slot 101a is provided on the conductive inner wall 101 c. The distance between the center of the arc-shaped conductive shell and the conductive shell can be set to be 7 millimeters, and the distance between the center of the arc-shaped conductive shell and the clamping groove can be set to be 7.3 millimeters.

It should be noted that the size of the part of the conductive sheet embedded in the card slot is positively correlated with the size of the card slot. And the size of conducting strip embedding draw-in groove internal part is less than or equal to the size of draw-in groove, realizes interference fit, and this kind of interference fit can make the stable contact between conducting strip and the draw-in groove.

For example, as shown in fig. 10, when the width of the conductive sheet is 2 mm, the width of the card slot may be set to 3 mm.

It can be understood that when the conducting strip moves due to extrusion, the conducting strip can be limited to move by arranging the clamping groove, so that the conducting strip is more reliably connected with the conducting shell.

In some embodiments, the card slot comprises: the inner wall of the conductive shell is sunken to form a groove which is consistent with the shape of the part, embedded into the clamping groove, of the conductive sheet.

That is to say, the shape of draw-in groove is unanimous with the shape that conducting strip imbedded in the draw-in groove, can make draw-in groove and the partial phase-match of conducting strip embedding in the draw-in groove, and then the realization conducting strip that can be better imbeds the draw-in groove, improves the reliability that conducting strip and conductive shell are connected.

For example, when the portion of the conductive plate inserted into the slot is circular arc, the slot may also be circular arc.

In an embodiment of the present disclosure, the conductive housing includes a conductive bezel; the projection of the printed circuit board to the conductive frame divides the conductive frame into a first frame part and a second frame part; the first frame body part and the welding disc are positioned on the same side of the printed circuit board; the card slot is located on the first frame portion. Therefore, the clamping groove and the welding disc are positioned on the same side of the printed circuit board.

It should be noted that the conductive sheet has an arc-shaped region, and the arc-shaped region and the pad are located on the same side of the printed circuit board. That is, the arc region, the pad, and the card slot are all located on the same side of the printed circuit board. Therefore, when the arc-shaped area of the conducting strip is connected with the conducting frame, at least part of the arc-shaped area can be embedded into the clamping groove in the first frame body part.

In some embodiments, the antenna further comprises:

The radio frequency front end module is used for providing a first electric signal or receiving a second electric signal obtained by converting a radiator.

The feeder line is used for transmitting the first electric signal to the radiator, or transmitting a second electric signal obtained by converting the radiator to the radio frequency front end module.

That is, the electrical signals on the printed circuit board can be directly guided to the conductive housing through the pads and the conductive sheet. On one hand, the area of the radiator can be increased, and the radiation efficiency and the radiation bandwidth of the terminal device are improved. On the other hand, when the wireless signal is radiated, the conducting strip bears partial electric signals, the electric signals borne by the conducting shell can be reduced, the condition that the electric signals in the conducting shell are exposed can be further reduced, and the radiation efficiency of the terminal equipment is further improved.
