Description

Technical Field

[0001] The present disclosure relates to the field of antennas, and more particularly to an electrical contact spring member for an antenna. Background Art

[0002] Antennas are commonly used in different types of electronic devices for sending and / or receiving electromagnetic fields (or signals), such as radio waves, microwaves, infrared radiation (IR), and visible light. Antennas act as transducers and convert electrical current signals into electromagnetic waves and vice versa. A controller or other electronic circuit board can be connected to the antenna in electrical communication for sending and receiving electrical current signals. The antenna can be connected to the controller or board at the electrical terminals of the board. Summary of the invention

[0003] Placing an antenna in electrical communication contact with a controller or other electronically programmable circuit board (PCB) presents certain challenges related to physical size, compression elasticity, signal paths between the controller and the antenna, and other challenges. These limitations may affect the quality of the electrical connection between the controller and, thus, the antenna performance. For example, a poor connection caused by an inadequate electrical connection at the connection point between the antenna and the controller may result in signal degradation or signal loss.

[0004] Some methods known in the prior art may solder the antenna or its associated electrical conductors directly to the PCB or electrical conductors. Other methods known in the prior art may include an electrical connector for connecting the antenna to the controller or other PCB. However, these methods can present additional limitations when designing an electrical device, as sufficient space may need to be provided to accommodate additional hardware and to allow sufficient space for the antenna to be connected / disconnected to the controller during installation and maintenance. For example, due to the design of the device or the available space at the connection location on the controller, it may be necessary to substantially disassemble the device to replace an antenna soldered to the controller. Therefore, these methods may present problems if the antenna or controller board needs to be replaced after assembly.

[0005] Various embodiments of the present disclosure relate to a spring member for an antenna. The spring member may be configured to undergo elastic deformation in response to a load applied thereto, and wherein the spring member may return to its original shape after the load is removed. Thus, the spring member may include a shape that provides compressive elasticity, which enables the spring member to withstand a certain amount of compressive force and compress to a certain range to provide sufficient electrical contact between the antenna and an electrical PCB (e.g., a controller), as will be further described herein.

[0031] Among those benefits and improvements that have been disclosed, other objects and advantages of the present disclosure will become apparent from the following description in conjunction with the accompanying drawings. Detailed embodiments of the present disclosure are disclosed herein; however, it should be understood that the disclosed embodiments are merely illustrations of the present disclosure that may be embodied in various forms. In addition, each example given of various embodiments of the present disclosure is intended to be illustrative rather than restrictive.

[0032] Figure 1 is a perspective view of a spring member 100 according to some embodiments.

[0033] The spring member 100 may be positioned between the antenna 102 and the electronic PCB 104, thereby connecting the antenna 102 to the PCB 104 in electrical communication for sending and receiving current signals between the antenna 102 and the PCB 104. In this regard, the spring member 100 may be made of a conductive material having certain compressive elastic properties that can provide a stable electrical connection between the antenna 102 and the PCB 104 while also allowing current signals to pass through the spring member 100 between the antenna 102 and the PCB 104. However, it should be understood by those of ordinary skill in the art that the type of material used to form the spring member 100 is not intended to be limiting and may include any of a variety of conductive materials, including but not limited to copper, gold, aluminum, silver, platinum, stainless steel, other metals, alloys thereof, or any combination thereof.

[0034] The spring member 100 may include a first arm 105 and a second arm 110. The first arm 105 may be configured to contact the antenna and the second arm 110 may be configured to contact the electronic PCB. In some embodiments, the first arm 105 and the second arm 110 may be elongated contact arms for contacting the antenna and the electronic PCB, respectively.

[0035] The first arm 105 may extend on a first plane, and the second arm 110 may extend on a second plane. The first arm 105 may be configured to contact the antenna 102, and the second arm 110 may be configured to contact the PCB 104. In some embodiments, the first plane of the first arm 105 and the second plane of the second arm 110 may be offset relative to each other. In addition, in some embodiments, when the spring member 100 is not in a compressed state, the first plane may also be parallel relative to the second plane. In other embodiments, the first plane and the second plane may extend on different planes, and the different planes may be oriented so that when the spring member 100 is not compressed, the corresponding planes intersect.

[0036] In some embodiments, the first arm 105 may include a tip 130. The tip 130 may be located at a distal end of the first arm 105 opposite the central portion 115, the tip 130 being configured to contact the antenna 102, thereby applying a compressive force to the first arm 105 and the spring member 100. The spring member 100 thereby forms an antenna signal loop between the antenna 102 and the PCB 104, the antenna signal loop thereby being further defined by the tip 130. In some embodiments, the tip 130 may be flared, and the antenna 102 may be configured to contact the first arm 105 at the tip 130 to improve the connection between the spring member 100 and the antenna 102, and to enable the antenna 102 to apply sufficient compressive force to the first arm 105 and the spring member 100.

[0037] The second arm 110 may be configured to be connected to the PCB 104 by a fastener. In some embodiments, the second arm 110 may be configured to be fixedly connected to the PCB 104. For example, in some embodiments, the second arm 110 may be coupled to the PCB 104 by soldering to the PCB 104. In this regard, the second arm 110 may include a solder pad 112. Thus, the second arm 110 may be fixedly connected to an electrical terminal of the PCB 104 by soldering to the PCB 104. This enables the antenna 102 to be installed / uninstalled from a device in which the antenna 102 and the PCB 104 are mounted, thereby enabling the antenna 102 to be connected / disconnected from the PCB by removing the entire antenna 102 (or antenna assembly) without having to disconnect any other intermediate components that may mechanically couple the antenna 102 to the PCB 104.

[0038] The spring member 100 may include a central portion 115 located between the first arm 105 and the second arm 110. The central portion 115 may be a flexible portion that integrally connects the first elongated contact arm to the second elongated contact arm. In this regard, the central portion 115 may serve as a spring arm of the spring member 100, which is configured to flexibly switch between a first state (e.g., a first position) and a second state (e.g., a second position) in response to a compressive force applied to the spring member 100. Thus, in response to a compressive force applied to the spring member 100, the central portion 115 bends, thereby enabling the first arm 105 to move toward the second arm 110. The spring member 100 may have a U-shape defined by the first arm 105, the second arm 110, and the central portion 115. When mounted between the antenna 102 and the PCB 104, the shape of the spring member 100 thereby provides a shortened signal path between the antenna 102 and the PCB 104 for providing improved signal conduction, for example, compared to when an electrical conductor is mounted therebetween.

[0039] The central portion 115 may be located at the first end 120 of the spring member 100, and the first arm 105 and the second arm 110 may extend from the central portion 115 and the first end 120 to a second end 125 opposite the first end 120. In some embodiments, the first arm 105 and the second arm 110 may extend in similar directions from the central portion 115 toward the second end 125. In some embodiments, the first arm 105 and the second arm 110 may extend in substantially similar directions from the central portion 115 toward the second end 125. In other embodiments, the first arm 105 may extend in a first direction (e.g., a first plane) from the central portion 115 toward the second end 125, and the second arm 110 may extend in a second direction (e.g., a second plane) from the central portion 115 toward the second end 125.

[0040] Figure 2 is a second perspective view of the spring member 100 according to some embodiments. Figure 3 is a bottom view of a spring member 100 according to some embodiments. Unless otherwise specifically referenced, Figure 2 and Figure 3 .

[0041] refer to Figure 2 , the size and shape of the spring member 100 can be such that the spring member 100 can connect the antenna 102 to the PCB 104 while overcoming the challenges posed by physical limitations associated with having such dimensions while still being able to reliably connect the antenna 102 to the PCB 104. The antenna 102 has a tip that is similar in size to the spring member 100.

[0042] In this regard, the spring member 100 may include dimensions having a width W, a length L, and a height H. In some embodiments, the width W of the spring member may be 2 mm or less. In some embodiments, the width W of the spring member 100 may be approximately 1.5 mm.

[0043] In some embodiments, the length L of the spring member 100 can be 2 mm or less. In some embodiments, the length L of the spring member 100 can be approximately 2 mm.

[0044] In some embodiments, when the spring member 100 is not under a compressive force, the height H of the spring member 100 can be 2 mm or less. In some embodiments, when the spring member 100 is not under a compressive force, the height H of the spring member 100 can be about 1.2 mm. In a preferred embodiment, when the spring member 100 is not under a compressive force, the width W of the spring member 100 can be 1.2 mm. However, as will be further described herein, the height H of the spring member 100 can increase or decrease in response to a compressive force.

[0045] The spring member 100 may include a protrusion 145 at the distal end of the first arm 105, such as at the tip 130, which is configured to contact the end of the antenna 102. When the antenna 102 applies a compressive force to the spring member 100, the end of the antenna 102 contacts the protrusion 145, and the spring member 100 is tensioned in response to the compressive force. In this regard, the protrusion 145 can cooperate with the central portion 115 to connect the antenna 102 to the PCB 104.

[0046] The spring member 100 may include a spacer 135. The spacer 135 may be a raised portion on the spring member 100, thereby forming a physical separation between the second arm 110 and the central portion 115. In addition, the spacer 135 may define a pad 140 at the second arm 110 for receiving solder material thereon to fixedly attach the spring member 100 to the PCB 104. The spacer 135 may also be configured to limit or prevent the solder material applied at the second arm 110 at the pad 140 from diffusing and gathering in its liquid state onto the central portion 115, thereby limiting the solder material from solidifying at the central portion 115 and affecting the tensioning performance of the spring member 100. The spacer 135 may extend over the width W of the spring member 100.

[0047] refer to Figure 3 , the pad 140 at the second arm 110 can be defined as having dimensions including a width W1 and a length L1. The width W1 can be substantially similar to the width W of the spring member 100, such as Figure 2 As shown. In addition, the length L1 of the pad 140 can be substantially similar to the distance between the separator 135 and the distal end of the second arm 110. In some embodiments, the size of the pad 140 can vary based on the available physical dimensions at the PCB 104. In some embodiments, each of the width W1 and the length L1 of the pad 140 can be less than 5 mm. In some embodiments, the width W1 and the length L1 of the pad 140 can be less than 4 mm, respectively. Each of the width W1 and the length L1 of the pad 140 in certain embodiments can be less than 3 mm. The width W1 and the length L1 of the pad 140 in other embodiments can be less than 2 mm, respectively. In a preferred embodiment, the pad 140 can have a width W1 of 1.3 mm and a length L1 of 1.2 mm.

[0048] Figure 4 is a side view of a spring member 100 according to some embodiments.

[0049] refer to Figure 4, the spring member 100 can move between a first position 150 and a second position 155. The spring member 100 can be in the first position 150 when no compressive force is applied to the spring member 100 and the first arm 105. In addition, the spring member 100 can be in the second position 155 in response to a specific compressive force applied to the spring member 100 and the first arm 105. In this regard, in some embodiments, the deflection distance between the first position 150 and the second position 155 of the spring member 100 can be proportional to the compressive force applied thereto.

[0050] When a certain compressive force is applied to the spring member 100, tension is applied to the central portion 115, and the first arm 105 moves in a downward direction toward the second arm 110 in response to the compressive force. When the compressive force is removed from the spring member 100, tension is removed from the central portion 115, and the central portion 115 relaxes and returns to its original position, which enables the first arm 105 to move away from the second arm 110 in an upward direction. In this regard, in some embodiments, in response to the compressive force, the angular relationship between the first arm 105 and the second arm 110 may increase or decrease corresponding to the amount of the compressive force applied to the spring member 100. In some embodiments, the angular relationship between the first arm 105 and the second arm 110 decreases in response to the compressive force applied to the first arm 105. In addition, in some embodiments, the angular relationship between the first arm 105 and the second arm 110 increases in response to the compressive force removed from the first arm 105 until the central portion 115 returns to its original relaxed state.

[0051] Accordingly, the spring member 100 and the central portion 115 may include a property such that a height H of the spring member 100, or a distance (e.g., displacement) between the first arm 105 and the second arm 110 when moving between the first position 150 and the second position 155, may vary in response to a particular compressive force applied to the spring member 100. In this regard, the spring member 100 may be designed such that the spring member 100 is able to withstand a certain amount of compressive force without displacing the first arm 105 to the extent that the first arm 105 is in direct contact with the second arm 110, thereby interrupting the signal loop formed by the first arm 105, the second arm, and the central portion 115.

[0052] The spring member 100, such as the central portion 115, can also be subjected to a certain amount of compressive force without exceeding the elastic limit of the spring member 100, thereby undergoing permanent mechanical deformation, while also being able to return to the first position 150 in response to the removal of the compressive force. For example, in some embodiments, the central portion 115 can include a yield stress of approximately 1110 MPa at the central portion 115, which in response to the stress causes the first arm 105 to displace a height equal to 0.6 mm. In some embodiments, the spring member 100 can receive a compressive force of approximately 1.15 N. In some embodiments, the spring member 100 can include a height H of 1.2 mm and displace a height equal to 0.6 mm in response to a compressive force of 1.15 N. In other embodiments, the spring member 100 can receive a compressive force of approximately 1.0 N. In addition, in some embodiments, the spring member 100 can displace 0.5 mm in response to a compressive force of 1.0 N.

[0053] However, it will be appreciated by those skilled in the art that the magnitude of the compressive force that the spring member 100 can withstand is exemplary and not limiting. Thus, the spring member 100 may include dimensions and properties that enable it to be used in certain applications where physical size is a limitation and the spring member 100 can withstand a certain amount of compressive force applied by the antenna 102. It will also be appreciated by those skilled in the art that, in accordance with the present disclosure, the spring member 100 can withstand additional compressive forces greater than 1.15 N without exceeding the elastic limit and experiencing permanent mechanical deformation.
