Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic view of a housing device 100 according to a first embodiment of the present invention. The housing arrangement 100 includes a housing 20 and a connecting structure 30. The connecting structure 30 includes a gourd-shaped spring T1 and a spring card K1, the gourd-shaped spring T1 is fixed on a PCB (Printed circuit board) board 40 by the spring card K1, and the gourd-shaped spring T1 is further electrically connected to the housing 20. That is, the spring clip K1 is used to fix the gourd-shaped spring T1 to the PCB board 40, and the gourd-shaped spring T1 is used to be electrically connected to the housing 20 after being fixed to the PCB board 40 by the spring clip K1. Wherein the coil diameter of the gourd-shaped spring 30 is gradually reduced from one end to a predetermined position of the gourd-shaped spring 30 and gradually increased from the predetermined position to the other end.

In one embodiment, the functional element 101 is an antenna module 10. The gourd-shaped spring 30 is electrically connected to the electrical connection region 21 of the housing 20 and the antenna module 10 mounted on the PCB 40. Thus, the antenna module 10 is electrically connected to the electrical connection region 21 of the housing 20 through the gourd-shaped spring 30, and the electrical connection region 21 of the housing 20 serves 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.
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 spring T1 is fixed on the PCB 40 and electrically connected to other functional elements mounted on the PCB 40 and electrically connected to the electrical connection region 21 of the housing 20. For example, the electrical connection region 21 of the case 20 is connected to the ground of a power circuit or the like mounted on the PCB 40, and the electrical connection region 21 of the case 20 is used as a common ground, or connected to a memory, a processor, a display chip or the like mounted on the PCB 40, and the electrical connection region 21 of the case 20 is used as a static electricity discharge ground. The functional device 101 is used as the antenna module 10 for the following description.
Specifically, in one embodiment, the gourd-shaped spring T1 includes a first end 31 and a second end 32, the first end 31 is fixed to the PCB 40 by a spring clip K1 and electrically connected to the antenna module 10, and the second end 32 is electrically connected to the inner surface of the electrical connection region 21 of the housing 20. The PCB 40 is substantially parallel to the inner surface of the housing 20, and the direction of expansion and contraction of the gourd-shaped 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.
More specifically, the gourd-shaped spring T1 is composed of a plurality of helically extending elastic coils, and the coil diameter of the gourd-shaped spring 30 gradually decreases from the first end 31 to a position substantially in the middle of the gourd-shaped spring 30 and gradually increases from the position substantially in the middle to the second end 32, that is, the predetermined position is a position substantially in the middle of the gourd-shaped spring 30. The first end 31 and the second end 32 may have the same or different diameters. The surface of the second end 32 of the gourd-shaped spring T1 is parallel to the inner surface of the housing 20 for maximizing the contact area, the first end 31 of the gourd-shaped spring T1 includes a horizontal section and an inclined section extending obliquely upward from the horizontal section, and the first end 31 and the second end 32 form an unclosed coil.
Therefore, when the housing 20 is subjected to an external force to generate a force relative to the PCB 40, and the gourd-shaped spring T1 can be twisted in other directions different from the telescopic direction due to the telescopic movement, so that the housing 20 can slightly move relative to the PCB 40, the gourd-shaped spring T1 and the housing 20 can follow the housing 20, and the contact position of the second end 32 of the gourd-shaped spring T1 and the housing 20 is maintained. Therefore, the connecting structure 30 is prevented from rubbing against the housing 20, and poor contact caused by surface abrasion of the housing 20 is not caused.
Referring also to fig. 3, the spring card K1 includes a bottom plate D1, and the bottom plate D1 includes a first side F1 (shown in fig. 2) and a second side F2. 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 gourd-shaped spring T1 is fixed to the second face F2 of the base plate D1.
Furthermore, a plurality of bent portions C1 extend from the side B1 of the bottom plate D1, and the bent portions are used for engaging with the gourd-shaped spring T1. Specifically, the side B1 of the spring card K1 has a bent portion C1 extending away from the PCB 40. The bent portion C1 may be an inverted L-shape. Each bent portion C1 of the inverted L shape and the second face F2 together form a receiving slot S1. The plurality of bent portions C1 may be connected to each other, or may be disposed at intervals as shown in fig. 3, that is, the side walls of the plurality of bent portions C1 are connected to each other or spaced from each other. Accordingly, the plurality of receiving grooves S1 may be separated and connected to each other.
The coil of the first end 31 of the gourd-shaped spring T1 is received in the receiving slot S1, so that the spring T1 is fixed to the spring clip K1 and further to the PCB 40.
As shown in fig. 3, three sides B1 of the spring card K1 each extend with a bending portion C1 in a direction away from the PCB 40, and the other side B1 is open, so that the first end 31 of the gourd-shaped spring T1 can slide into the receiving slots S1 of the spring card K1 from the side B1 of the opening. The first end 31 of the gourd-shaped spring T1 is fixed on the PCB 40 by a spring clip K1 and then electrically contacts the antenna module 10.
A stop N1 is further disposed at the outer edge of the side B1 of the opening, preferably, the stop N1 is made of an elastic material, and when the device is installed, the first end 31 of the gourd-shaped spring T1 slides in from the side B1 of the opening until the inner side of the stop N1 abuts against the outer edge of the first end 31 of the gourd-shaped spring T1. During installation, the stopper N1 is compressed, and after the gourd-shaped spring T1 enters, the stopper N1 is bounced to match with the plurality of accommodating grooves S1 to fix the gourd-shaped spring T1 on the bottom plate D1 of the spring card K1. Obviously, in some embodiments, the stopper N1 may not be made of elastic material, but rather may slide along the side B1 of the opening by using the elastic property of the coil of the first end 31 of the gourd-shaped spring T1 in the diameter direction. When the inner side of the slide-down stopper N1 abuts against the outer edge of the first end 31 of the gourd-shaped spring T1, the coils of the first end 31 of the gourd-shaped spring T1 return to their shapes and abut against the side walls of the stopper N1 and the plurality of receiving grooves S1, so that the stopper cooperates with the plurality of receiving grooves S1 to fix the gourd-shaped spring T1 to the bottom plate D1 of the spring card K1.
The material of the gourd-shaped spring T1 is a metal material, such as aluminum, copper, iron, and the like. In some embodiments, the surface of the gourd-shaped spring T1 is further plated with gold, nickel, or the like.
The housing 20 is a metal housing, for example, a housing made of aluminum alloy, the housing 20 is a rear case (a rear cover of the battery), and the second end 32 of the gourd-shaped spring T1 is abutted against the inner surface of the housing 20 for electrical connection.
