The housing arrangement 100 includes a housing 20 and a connecting structure 30. The connecting structure 30 includes an elastic element 301, the elastic element 301 is located between the housing 20 and a Printed Circuit Board (PCB) 40, and the elastic element 301 is fixed on the PCB 40 and electrically connected to the housing 20. Wherein the elastic element 301 maintains the connection position with the housing 20 when the housing 20 moves relative to the PCB board 40.
The elastic element 301 is a spring T1, the spring T1 is located between the housing 20 and the PCB 40, and the spring T1 is fixed on the PCB 40 and electrically connected to the housing 20.
As shown in fig. 1, the housing device 100 further includes a functional component 101 mounted on the PCB 40, the housing 20 includes an electrical connection region 21, and the spring T1 is fixed on the PCB 40 and electrically connected to the functional component 10 mounted on the PCB 40 and electrically connected to the electrical connection region 21 of the housing 20.
In this embodiment, the functional element 101 is an antenna module 10, and the spring T1 is fixed on the PCB 40 and then electrically connected to the antenna module 10 mounted on the PCB 40 and electrically connected to the electrical connection area 21 of the housing 20, so as to establish electrical connection between the antenna module 10 and the electrical connection area 21 of the housing 20, and use the electrical connection area 21 of the housing 20 as a radiator of the antenna module 10. The electrical connection region 21 of the housing 20 may be the entire housing 20 or a partial region of the housing 20. When the electrical connection region 21 is a partial region of the housing 20, it may be located at the middle position and the two side positions of the housing 20, and the shape may be square, circular, triangular, and the like.
When the spring T1 is fixed on the PCB 40 and then electrically connected to the antenna module 10 mounted on the PCB 40, the housing device 100 is an antenna device. The functional device 101 is taken as the antenna module 10 for the following description.
The PCB 40 may be an antenna circuit board for mounting and carrying the antenna module 10. The PCB 40 may also be a main board of a terminal device, and in addition to the antenna module 10, other functional elements, such as a processor, a memory, etc., are installed. In some embodiments, the PCB board 40 may also be a part of the antenna module 10. In other embodiments, the functional element 101 may be another element, for example, a power circuit mounted on the PCB 40, and the spring T1 is fixed on the PCB 40 and then connected to the ground of the power circuit mounted on the PCB 40 and the electrical connection region 21 of the housing 20, so that the electrical connection region 21 of the housing 20 is used as a common ground. Alternatively, the functional device 101 may be a memory, a processor, a display chip, etc. mounted on the PCB 40, and the spring T1 is fixed on the PCB 40 and then connected to the memory, the processor, the display chip, etc. mounted on the PCB 40 and the electrical connection region 21 of the case 20, so that the electrical connection region 21 of the case 20 is used as a static electricity discharge ground.
Specifically, the spring T1 includes a first end 31 and a second end 32, the first end 31 is fixedly connected to the PCB 40 and electrically connected to the antenna module 10, the second end 32 is connected to the inner surface of the housing 20 in an abutting manner, and particularly, the second end 32 is connected to the inner surface of the electrical connection area 21 of the housing 20 in an abutting manner. The PCB 40 is substantially parallel to the inner surface of the housing 20, and the expansion and contraction direction of the spring T1 is substantially along the arrangement direction of the first end 31 and the second end 32, i.e. the direction perpendicular to the PCB 40 or the inner surface of the housing 20.
Therefore, when the housing 20 is subjected to an external force to generate a force relative to the PCB 40, the spring T1 and the housing 20 can move together with the housing 20 while maintaining the contact position, i.e., the connection position, of the second end 32 of the spring T1 with the housing 20 when the housing 20 moves relative to the PCB 40 due to the fact that the spring T1 can move telescopically and can also twist in other directions different from the telescopic direction. Therefore, friction between the connecting structure 30 and the housing 20 is avoided, and poor contact caused by surface abrasion of the housing 20 is not caused.
The spring T1 is a coil spring, and the material of the spring T1 is a metal material. In some embodiments, the surface of the spring T1 is also plated with gold, nickel, or the like.
The housing 20 is a metal housing, such as an aluminum alloy housing, the housing 20 is a rear case (a battery cover), and the second end 32 of the spring T1 is abutted against the inner surface of the housing 20.
In this embodiment, the first end 31 of the spring T1 may be fixed on the PCB 40 by soldering, and the second end 32 of the spring T1 may abut against the housing 20 by elastic interference.
Wherein the spring T1 is composed of a plurality of spirally extending elastic coils, the surface of the second end 32 of the spring T1 is parallel to the inner surface of the housing 20 for maximizing the contact area, and the first end 31 of the spring T1 includes a horizontal section and an inclined section extending obliquely upward from the horizontal section to form an unclosed coil.
Referring to fig. 3, the housing device 100 shown in fig. 1 is different in that, in another embodiment, the first end 31 of the spring T1 can be integrally formed with the PCB board 40, and the second end 32 of the spring T1 can also be integrally formed with the housing 20. That is, at least one of the PCB board 40 and the case 20 is integrally formed with the spring T1.
Please refer to fig. 4 and fig. 5, which are schematic views of a housing device 200 according to a second embodiment. The difference from the first embodiment is that in this embodiment, the connecting structure 30 further includes a spring clip K1, and the spring clip K1 is used to fix the spring T1 on the PCB board 40. The spring card K1 includes a bottom panel D1, the bottom panel D1 includes a first face F1 (shown in fig. 2) and a second face F2 that are opposite. The first face F1 of the bottom plate D1 is opposite to the PCB 40 and fixed on the PCB 40. The first end 31 of the spring T1 is secured to the second face F2 of the base plate D1.

The coil of the first end 31 of the spring T1 is received in the receiving slot S1, thereby securing the spring T1 to the spring card K1 and, in turn, to the PCB board 40.

During installation, the stopper N1 is compressed, and after the spring T1 is inserted, the stopper N1 is sprung up to cooperate with the plurality of receiving slots S1 to fix the spring T1 on the bottom plate D1 of the spring card K1. Obviously, in some embodiments, the stopper N1 may not be an elastic material, but rather may slide along the side B1 of the opening by the elasticity of the coil of the first end 31 of the truncated cone shaped spring T1 in the diameter direction. When the inner side of the stopper N1 abuts against the outer edge of the first end 31 of the truncated cone shaped spring T1, the coils of the first end 31 of the truncated cone shaped spring T1 return to the original shape and abut against the side walls of the stopper N1 and the plurality of receiving grooves S1, so that the stopper N1 cooperates with the plurality of receiving grooves S1 to fix the truncated cone shaped spring T1 on the bottom plate D1 of the spring card K1.
The spring card K1 is made of a metal material, such as copper, aluminum, iron, and the like.
In other embodiments, the first end 31 of the spring T1 may be fixed to the PCB board 40 by a snap connection, riveting, or the like. The connection manner of the first end 31 of the spring T1 and the PCB board 40 in the embodiment of the present invention is not limited.

As shown in fig. 8, three sides B2 of the spring card K2 each extend with a bending portion C2 in a direction away from the housing 20, and the other side B2 is open, so that the second end 32 of the spring T1 can slide into the receiving slots S2 of the spring card K2 from the side B2 of the opening. The second end 32 of the spring T1 is secured to the PCB board 40 by a spring tab K2 and is also in electrical contact with the housing 20. Wherein the spring card K2 is made of metal material, and the spring T1 is electrically contacted with the shell 20 through the spring card K2.
Similarly, a stop N2 is also provided at the outer edge of the side B2 of the opening of the spring card K2, preferably, the stop N2 is made of an elastic material, and when the spring card K2 is installed, the second end 32 of the spring T1 slides in from the side B2 of the opening until the inner side of the stop N2 abuts against the outer edge of the second end 32 of the spring T1. During installation, the stopper N2 is compressed, and after the spring T1 is inserted, the stopper N12 is sprung to cooperate with the plurality of receiving slots S2 to fix the second end 32 of the spring T1 to the bottom plate D2 of the spring card K2. In some embodiments, the stop N2 may not be an elastic material, but rather may slide along the side B2 at the opening by the diametrical elasticity of the coils at the second end 32 of the truncated cone spring T1. When the inner side of the second stopper N2 abuts against the outer edge of the second end 32 of the truncated cone shaped spring T1, the coil of the second end 32 of the truncated cone shaped spring T1 returns to its original shape and abuts against the stopper N2 and the side walls of the plurality of receiving grooves S2, so that the stopper N2 cooperates with the plurality of receiving grooves S2 to fix the truncated cone shaped spring T1 on the bottom plate D2 of the spring card K2.

The spring T1 may be cylindrical, the first end 31 and the second end 32 are two end faces of the cylindrical spring T1, and the diameter of the coils of the spring T1 is substantially equal from the first end 31 to the second end 32.
The spring T1 may also be thin in the middle and fat in the two ends, and the first end 31 and the second end 32 are the two end faces of the gourd-shaped spring T1. That is, the coil diameter of the spring T1 gradually decreases from the first end 31 to a position approximately in the middle of the spring T1, and then gradually increases from a position approximately in the middle of the spring T1 to the second end 32, wherein the coil diameter of the first end 31 and the coil diameter of the second end 32 may be equal or unequal.
