Description

Technical Field

[0001] The present disclosure relates to a signal transmission device.

Background Art

[0002] The content described in this part only provides background information related to the present disclosure and does not constitute the prior art.

[0003] A connector is an electronic component that connects devices to each other. The connector is disposed between devices and transmits signals that have been transmitted or received. The connector can be connected to a printed circuit board (PCB), an antenna board, a filter, etc. The connector mainly takes the form of being inserted into the terminals of a device in order to connect devices to each other.

[0004] In order for the characteristics of the connector to be exerted without problems, the distance between devices must be maintained at a certain distance. If the distance between devices is not constant, the connector may not be accurately contacted with the terminals of the device. If the connector is not properly contacted, various problems may occur. Specifically, the electrical signal may not be transmitted smoothly, noise may occur, the communication quality may be degraded, or the communication speed may be decreased.

[0005] Devices are not always used in a fixed state. When the distance between devices changes, the contact between the device and the connector is reduced, and problems may occur in the transmission of electrical signals. That is, since the distance between devices cannot always be maintained constant, a connector or a connector connection structure whose performance does not deteriorate even when the distance between devices changes is required.

[0018] Referring to Figures 1 to 4, the signal transmission apparatus 1 includes all or part of a shielding structure 100, a cover 130, a first dielectric member 200, a signal transmission line 300, a first connector 400, a first elastic member 500, a substrate 600, a second connector 700, a second dielectric member 800, and a second elastic member 900.

[0019] The shielding structure 100 blocks electromagnetic waves and prevents signal interference. According to one embodiment, the shielding structure 100 may be made using aluminum or magnesium. The shielding structure 100, together with the lid 130, forms a closed structure that protects components placed inside from external interference. The shape of the shielding structure 100 is not limited to the shape disclosed in Figure 2.

[0020] The shielding structure 100 may have at least a portion of its upper surface open. A lid 130 is fitted to the open portion of the upper surface of the shielding structure 100. The lid 130 includes a first through hole 150. According to one embodiment, the lid 130 may be seated in a receiving groove 120 of the shielding structure 100. Referring to Figure 2, the receiving groove 120 may be formed on the upper surface of the shielding structure 100.

[0021] According to one embodiment, the shielding structure 100 may be a shield can. Shield cans are used in communication equipment, computers, electronic devices, etc. A shield can can protect the electronic components inside from external electromagnetic waves.

[0022] The shielding structure 100 includes an accommodating space 110 and a fourth through-hole 170.

[0023] The accommodating space 110 is a space formed inside the shielding structure 100. Inside the accommodating space 110, the first dielectric member 200, the second dielectric member 800, and the signal transmission line 300 can be accommodated. The shape of the accommodating space 110 is not limited to the shapes disclosed in FIGS. 2 and 4.

[0024] The first through-hole 150 is formed in the lid 130. The first connector 400 is inserted inside the first through-hole 150. According to an embodiment, the diameter of the first through-hole 150 can be formed larger than the diameter of the second through-hole 210.

[0025] The fourth through-hole 170 is formed in the lower surface of the shielding structure 100. The second connector 700 can be disposed inside the fourth through-hole 170.

[0026] The first dielectric member 200 is disposed in the accommodating space 110 of the shielding structure 100. According to an embodiment, the upper surface of the first dielectric member 200 can be disposed to contact the lower surface of the lid 130.

[0027] The first dielectric member 200 improves electrical stability and assists the stable operation of the signal transmission device 1. According to an embodiment, the first dielectric member 200 can be formed using Teflon (registered trademark).

[0028] A second through-hole 210 can be formed in the center of the first dielectric member 200. A part of the signal transmission line 300 can be inserted inside the second through-hole 210. In this case, a part of the signal transmission line 300 can be disposed to penetrate the outer portion of the first dielectric member 200.

[0029] The signal transmission line 300 may be located between the first connector 400 and the second connector 700. In this case, the second connector 700 transmits a signal to the signal transmission line 300, and the signal transmission line 300 can transmit a signal to the first connector 400 or the first biasing member 500.

[0030] According to one embodiment, the signal transmission line 300 may penetrate the outer portion of the first dielectric member 200. One side of the signal transmission line 300 is in contact with the first biasing member 500.

[0031] A third through-hole 310 may be formed on one side of the signal transmission line 300. The third through-hole 310 may be located inside the second through-hole 210.

[0032] The other end of the signal transmission line 300 may be located inside the fourth through-hole 170. The other end of the signal transmission line 300 may be connected to the second connector 700.

[0033] The diameter of the third through-hole 310 may be smaller than the diameter of the second through-hole 210. In this case, the first biasing member 500 may be positioned to contact the third through-hole 310.

[0034] The first connector 400 may be positioned to pass through the first through-hole 150 and the third through-hole 310. A portion of the first connector 400 may be positioned inside the second through-hole 210.

[0035] The signal transmission device 1 according to this disclosure may be coupled with other devices (not shown). In this case, the first connector 400 connects the signal transmission device 1 to the other devices. For example, the other devices may be filters (not shown). In this case, the signal transmission device 1 may be connected to the filter. In this case, the first connector 400 is connected to the filter. The first connector 400 may have a structure that is unified with the filter.

[0036] The shape of the first connector 400 is not limited to the shapes disclosed in Figures 1 to 4. Any shape that allows simultaneous connection of the signal transmission device 1 and other devices may qualify as the shape of the first connector 400.

[0037] In one embodiment, the position of the first connector 400 can change. Specifically, the first connector 400 can move up, down, left, and right while being located inside the second through-hole 210. That is, the position of the first connector 400 inside the second through-hole 210 can change. Even when the position of the first connector 400 changes in this way, contact between the third through-hole 310, the first biasing member 500, and the first connector 400 is maintained. This is because the first biasing member 500 undergoes elastic deformation and comes into contact with the third through-hole 310 and the first connector 400. Even when the position of the first connector 400 changes, the signal transmission device 1 can transmit signals because the third through-hole 310, the first biasing member 500, and the first connector 400 are in contact.

[0038] When the signal transmission device 1 according to this disclosure is coupled with other devices (not shown), the distance between the signal transmission device 1 and the other devices may change. As described above, the position of the first connector 400 may change. Even when the distance between the signal transmission device 1 and the other devices changes, the first connector 400 can maintain contact with the signal transmission device 1 and the other devices. That is, even when the distance between the signal transmission device 1 and the other devices changes, the signal transmission device 1 can transmit signals to the other devices.

[0039] The central axes of the first through-hole 150 to the third through-hole 310 may coincide with each other. If the central axes of the first through-hole 150 to the third through-hole 310 do not coincide with each other, the first connector 400 and the first biasing member 500 are difficult to position inside the first through-hole 150 to the third through-hole 310. If the central axes of the first through-hole 150 to the third through-hole 310 coincide with each other, the first connector 400 and the first biasing member 500 are positioned inside the first through-hole 150 to the third through-hole 310 and can move up, down, left, and right.

[0040] The first biasing member 500 is positioned between the signal transmission line 300 and the first connector 400. The first biasing member 500 is in contact with the signal transmission line 300 and the first connector 400. The signal transmission line 300 transmits a signal to the first biasing member 500, and the first biasing member 500 transmits a signal to the first connector 400.

[0041] In one embodiment, the first biasing member 500 is positioned to penetrate the first through-hole 150 and the third through-hole 310. In another embodiment, the first biasing member 500 is positioned inside the second through-hole 210. In this case, at least a portion of the first biasing member 500 may protrude outside the second through-hole 210. In yet another embodiment, one side of the first biasing member 500 may contact the lower surface of the first connector 400.

[0042] The first biasing member 500 may include a plurality of support bodies 510 extending from one surface. Referring to Figures 1 to 4, the plurality of support bodies 510 are disclosed to include the first support body 510A to the fourth support body 510D, but the plurality of support bodies 510 are not limited to the number and shape disclosed in Figures 1 to 4.

[0043] The multiple support members 510 may include at least one bending portion 530. The number of bending portions and the bending angle will affect the degree to which the multiple support members 510 are deformed, the biasing force of the multiple support members 510, the contact area, etc. Here, the contact area refers to the contact area between the first biasing member 500 and the first connector 400, or the contact area between the first biasing member 500 and the third through hole 310.

[0044] Referring to Figures 1 to 4, at least one bent portion 530 is disclosed as including a first bent portion 530A to a third bent portion 530C, but the number and shape of at least one bent portion 530 are not limited to those disclosed in Figures 1 to 4.

[0045] The inner portions of the multiple support members 510 contact the outer circumferential surface of the first connector 400. The outer portions of the multiple support members 510 contact the inner circumferential surface of the third through-hole 310.

[0046] The multiple supports 510 can be elastically deformed by the third through-hole 310. Referring to Figure 4, the multiple supports 510 are compressed by the third through-hole 310. That is, the multiple supports 510 remain elastically deformed while in contact with the third through-hole 310 and the first connector 400.

[0047] The first connector 400 and the first biasing member 500 can be joined to each other. According to one embodiment, the first connector 400 and the first biasing member 500 can be joined to each other using welding or soldering. In this case, when the first connector 400 moves, the first biasing member 500 also moves with it. The degree of elastic deformation and shape of the first biasing member 500 differ depending on the position in which it is positioned. The first biasing member 500 maintains contact with the third through-hole 310 and the first connector 400 even when its position changes. In order to maintain contact, the first connector 400 can receive signal transmission from the signal transmission line 300 regardless of its position.

[0048] The substrate 600 may be located below the shielding structure 100. The substrate 600 is connected to the second connector 700. The substrate 600 transmits signals to the second connector 700. According to one embodiment, the substrate 600 may be a PCB (Printed Circuit Board).

[0049] The second connector 700 may be connected to the substrate 600. The second connector 700 may be located inside the fourth through-hole 170 formed on the lower surface of the shielding structure 100. The second connector 700 may be connected to the other side of the signal transmission line 300. The shape of the second connector 700 is not limited to the shape disclosed in Figure 2. Any shape that connects the signal transmission line 300 and the substrate 600 simultaneously may qualify as the shape of the second connector 700.

[0050] The second dielectric member 800 may be arranged to surround the second connector 700. In this case, the second connector 700 may pass through the center of the second dielectric member 800. The second dielectric member 800 improves electrical stability and assists in the stable operation of the signal transmission device 1. According to one embodiment, the second dielectric member 800 may be formed using Teflon®.

[0051] The above description is merely illustrative of the technical concept of this embodiment, and any person with ordinary skill in the art to which this embodiment belongs will be able to make various modifications and variations without departing from the essential characteristics of this embodiment. Therefore, this embodiment is for illustrative purposes only, not to limit the technical concept of this embodiment, and the scope of the technical concept of this embodiment is not limited by this embodiment.
