All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
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 cylindrical spring T1, a first spring card K1 and a second spring card K2 having a plurality of protrusions E1. The cylindrical spring T1 is fixed on a PCB (Printed circuit board) board 40 by the first spring card K1, and the cylindrical spring T1 is fixedly connected with the second spring card K2 and electrically connected with the housing 201 by a plurality of protrusions E1 of the second spring card K2. Wherein the coil diameters of the cylindrical spring T1 are equal from one end to the other.
The housing 20 includes an electrical connection region 21 as shown in fig. 2, the housing device 100 further includes a functional element 101 mounted on the PCB 40, and the cylindrical spring 30 is fixed on the PCB 40 by the first spring card K1 and electrically connected to the functional element 101 mounted on the PCB 40, and is electrically connected to the electrical connection region 21 of the housing 20 by the protrusions E1 of the second spring card K2.
In an embodiment, the functional element 101 is an antenna module 10, the cylindrical spring T1 is fixed on the PCB 40 by the first spring clip K1 and then electrically connected to the antenna module 10 mounted on the PCB 40, and the second spring clip K2 is 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 the electrical connection area 21 of the housing 20 is used 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 taken as the antenna module 10 for the following description.
Specifically, in one embodiment, the cylindrical spring T1 includes a first end 31 and a second end 32, the first end 31 is fixed to the PCB 40 and electrically connected to the antenna module 10 through a first spring clip K1, and the second end 32 is electrically connected to the inner surface of the electrical connection region 21 of the housing 20 through a second spring clip K2. In one embodiment, the second spring tab K2 abuts against the inner surface of the electrical connection region 21 of the housing 20 to make electrical connection. The first end 31 and the second end 32 are two ends of the cylindrical spring T1. The cylindrical spring T1 is a helical cylindrical spring, and the coil diameters of the cylindrical spring T1 are substantially equal from the first end 31 to the second end 32. Specifically, the cylindrical spring T1 is composed of a plurality of elastic coils extending spirally, and the first end 31 and the second end 32 of the cylindrical spring T1 each include a horizontal section and an inclined section extending obliquely upward from the horizontal section to form an unclosed coil.
The PCB 40 is substantially parallel to the inner surface of the housing 20, and the extension and retraction direction of the cylindrical 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 and acts on the PCB 40, the cylindrical spring T1 and the second spring tab K2 may follow the housing 20 to move together when the housing 20 slightly moves relative to the PCB 40 due to the fact that the cylindrical spring T1 can be extended and retracted and can also be twisted in other directions different from the extending and retracting directions, and the contact position between the second end 32 of the cylindrical spring T1 and the second spring tab K2 and the housing 20 is kept unchanged. Therefore, the connecting structure 30 is prevented from rubbing against the housing 20, and poor contact caused by abrasion of the inner surface of the housing 20 is not caused.
Please refer to fig. 3, which is an exploded and assembled view of the connecting structure 30. The first spring card K1 includes a bottom panel D1, the bottom panel D1 includes a first face F1 (shown in fig. 1) 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.
Furthermore, a plurality of bent portions C1 extend from the side B1 of the bottom plate D1, and the bent portions are engaged with the spring T1. Specifically, the side B1 of the first 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 first 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 first receiving grooves S1 may be separated and connected to each other.
The coils of the first end 31 of the cylindrical spring T1 are received in the receiving slot S1, thereby securing the cylindrical spring T1 to the first spring card K1 and, in turn, to the PCB board 40.
As shown in fig. 3, the three sides B1 of the first 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 cylindrical spring T1 can slide into the first receiving slots S1 of the first spring card K1 from the side B1 of the opening. The first end 31 of the cylindrical spring T1 is fixed to the PCB board 40 by a first spring card K1 and then electrically contacts the antenna module 10.
A first stop N1 is further disposed at the outer edge of the side B1 of the opening, preferably, the first stop N1 is made of an elastic material, and when the device is installed, the first end 31 of the cylindrical spring T1 slides in from the side B1 of the opening until the inner side of the first stop N1 abuts against the outer edge of the first end 31 of the cylindrical spring T1. During installation, the first stopper N1 is compressed, and after the cylindrical spring T1 is inserted, the first stopper N1 is sprung to cooperate with the first receiving grooves S1 to fix the first end 31 of the cylindrical spring T1 to the bottom plate D1 of the first spring card K1. Obviously, in some embodiments, the first stopper N1 may not be made of elastic material, but rather, it slides along the side B1 of the opening by the elasticity of the first end 31 of the cylindrical spring T1 in the diameter direction of the coil. When the inner side of the first stopper N1 abuts against the outer edge of the first end 31, the coils of the first end 31 return to the original shape and abut against the side walls of the first stopper N1 and the plurality of receiving slots S1, so that the first stopper N1 cooperates with the plurality of receiving slots S1 to fix the cylindrical spring T1 to the bottom plate D1 of the first spring card K1. The first end 31 of the cylindrical spring T1 is fixed to the PCB board 40 by a first spring card K1 and then electrically contacts the antenna module 10.
Referring also to fig. 4, fig. 3 is a schematic view of the second spring card K2 from an upside down view. The second spring card K2 includes a bottom plate D2, the bottom plate D2 includes a third face F3 and a fourth face F4 opposite to each other, the plurality of protrusions E1 are disposed on the third face F3 and electrically connected to the inner surface of the electrical connection region 21 of the housing 20, and the second end 32 of the spring T1 is fixed to the fourth face F4. In one embodiment, the protrusions E1 of the second spring card K2 abut against the inner surface of the electrical connection region 21 of the housing 20 and are electrically connected, so that the second end 32 is electrically connected to the electrical connection region 21 of the housing 20 through the protrusions E1 of the second spring card K2. As shown in fig. 4, the number of the plurality of protrusions E1 is 3, and obviously, the number of the protrusions E1 may be any suitable value, such as 2, four, etc.
Similarly, a plurality of bent portions C2 extend from the side B1 of the bottom panel D2, and the bent portions C2 are configured to engage with the second end 32 of the cylindrical spring T1. Specifically, the side B2 of the second spring card K2 has a bent portion C2 extending away from the housing 20. The bent portion C2 may be an inverted L-shape. Each inverted L-shaped bent portion C2 and the fourth surface F4 together form a second receiving cavity S2. The plurality of bent portions C2 may be connected to each other, or may be disposed at intervals as shown in fig. 4, that is, the side walls of the plurality of bent portions C2 are connected to each other or spaced from each other. Accordingly, the plurality of second receiving grooves S2 may be separated and connected to each other.
As shown in fig. 4, the three sides B2 of the second 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 cylindrical spring T1 can slide into the second receiving slots S2 of the second spring card K2 from the side B2 of the opening, and is fixed to the second spring card K2. The second end 32 of the cylindrical spring T1 is fixed to the second spring tab K2, and then electrically contacts the electrical connection region 21 of the housing 20 through the second spring tab K2 and the protrusion E1 thereof. Wherein the second spring card K2 is made of metal material, and the cylindrical spring T1 is electrically contacted with the electrical connection region 21 of the housing 20 through the spring card K2 and the protruding portion E1 thereof.
A second stopper N2 is further disposed at the outer edge of the side B2 of the opening of the second spring card K2, preferably, the second stopper N2 is made of an elastic material, and when the spring card K2 is installed, the second end 32 of the second spring T1 slides in from the side B2 of the opening until the inner side of the second stopper N2 abuts against the outer edge of the second end 32 of the cylindrical spring T1. During installation, the second stopper N2 is compressed, and after the cylindrical spring T1 is inserted, the second stopper N2 is sprung to cooperate with the second receiving grooves S2 to fix the second end 32 of the cylindrical spring T1 to the bottom plate D2 of the second spring card K2. Likewise, in some embodiments, the second stopper N2 may not be elastic, but rather may slide along the side B2 at the opening by virtue of the diametrical elasticity of the coils at the second end 32 of the cylindrical spring T1. When the inner side of the second stopper N2 abuts against the outer edge of the first end 31, the coil of the second end 31 recovers its shape and abuts against the side walls of the second stopper N2 and the second receiving grooves S2, so that the second stopper N2 cooperates with the second receiving grooves S2 to fix the cylindrical spring T1 to the bottom plate D2 of the second spring clip K2.
The projections E1 are convex cylinders or convex hemispheres projecting from the third surface F3 in the direction of the housing 20.
The cylindrical spring T1 is made of a metal material. In some embodiments, the surface of the cylindrical spring T1 is also plated with gold, nickel, or the like.
The case 20 is a metal case, for example, a case made of an aluminum alloy material, the case 20 is a rear case (a rear cover of the battery), and the second spring card K2 is abutted against and electrically connected to an inner surface of the case 20.
