Description

TECHNICAL FIELD

[0001] The utility model relates to a video adapter cable technical field, specifically a kind of photoelectric hybrid cable of Type-C signal conversion HDMI signal. BACKGROUND

[0002] USB Type-C connector is smaller than traditional USB interface, and has the advantages of reversible insertion and higher transmission rate, so it is rapidly adopted by personal computers, mobile terminals such as mobile phones and other consumer electronic products. In actual use, since the screen size of personal mobile computers and other mobile terminal devices is small, transmitting the content of the small-size screen to a larger-size display device can achieve better viewing effect. However, at present, display devices using USB Type-C are still relatively few, and display devices with HDMI interface are still in the mainstream position. HDMI interface 1 can realize high-speed transmission of high-definition digital signals, and the current HDMI 2.1 interface still has the advantage of high transmission rate compared with USB Type-C. Therefore, the demand for using an adapter cable to transmit a USB Type-C signal source to an HDMI display device is relatively widespread.

[0003] The HDMI interface of most display devices is located on the backplane of the display device, and it is difficult to directly visually observe the HDMI interface, which leads to difficult alignment and plugging. Even if the interface is inserted, it is difficult to observe whether the plug is in place, and if it is not in place, it may affect the transmission effect of the display signal. Therefore, when plugging, the display device usually needs to be moved, and after plugging is completed, it is moved back to the original position, which increases the operation complexity. Since it is difficult to visually observe, when pulling out the interface, the cable itself is usually pulled, which can easily damage the cable. Therefore, there is an urgent need for a Type-C signal conversion HDMI signal photoelectric hybrid cable that can assist in observing the interface position and plugging state when plugging the cable interface. SUMMARY

[0004] The purpose of the utility model is to facilitate direct visual observation and plugging of the interface behind the backplane of a large display device, and to facilitate alignment. In view of this problem in the prior art, the embodiment of the present application provides a Type-C signal conversion HDMI signal photoelectric hybrid cable provided with a smooth surface. The smooth surface has the function of mirror reflection, which is beneficial to realizing real-time observation of the backplane interface when plugging the cable and improving the interface plugging efficiency.

[0005] To achieve the above-mentioned utility model purposes, the utility model provides the following technical solutions:

[0006] An optoelectrical hybrid cable for converting Type-C signal into HDMI signal, comprising an HDMI interface, a USB Type-C interface and an optical cable, the USB Type-C interface and one end of the optical cable are connected, the HDMI interface and the other end of the optical cable are connected, and a smooth surface capable of generating mirror reflection is arranged on the sheath of the optical cable.

[0007] Preferably, a support strip is arranged on the sheath, and the support strip is rotationally connected to one end of the sheath and the smooth surface.

[0008] Preferably, a first sliding groove is arranged on the sheath, a matching first sliding block is arranged on the first sliding groove, the first sliding block is connected to one end of the optical cable and the smooth surface, and the first sliding block slides along the axial line of the optical cable.

[0009] Preferably, a hard sleeve capable of sliding is arranged around the sheath, and the diameter of the hard sleeve is smaller than the width of the flat surface of the HDMI interface.

[0010] Preferably, the hard sleeve is provided with a separable connection or an opening along the axial line of the optical cable.

[0011] Preferably, the hard sleeve comprises a first sleeve and a second sleeve, the first sleeve and the second sleeve are rotationally connected, the axial line of the rotation axis is perpendicular to the optical cable, and a first channel is arranged between the rotation axis and the hard sleeve.

[0012] Preferably, the first sleeve and the second sleeve are rotationally damped.

[0013] Preferably, the optical cable is flat, and the smooth surface is arranged on the flat surface of the sheath.

[0014] Preferably, the smooth surface is arranged around the sheath, and the smooth surface is provided with a separable connection along the axial line of the optical cable.

[0015] Preferably, a plurality of smooth surfaces are arranged on the flat surface.

[0016] Compared with the prior art, the present application has the following beneficial effects:

[0017] 1. In view of the problem that the HDMI interface is usually arranged on the back plate of a display device, and it is inconvenient to observe the interface during plugging, a smooth surface is arranged on the optical cable, and the smooth surface is aligned with the interface position on the back plate of the display device by bending and moving the optical cable during use, so that the state of the interface during plugging is observed, and the operation efficiency of the user is improved.

[0018] 2. By setting the smooth surface to rotate around the axis perpendicular to the optical cable, the smooth surface can be rotated to an angle that is convenient for observing the interface. When the smooth surface is rotated to the same plane as the optical cable, not only can the passability of the optical cable between the backboard and the wall be improved, but also the smooth surface can be as close as possible to the interface position for convenient observation; and the space occupation is reduced, which is beneficial to the storage of the optical cable.

[0019] 3. The smooth surface is set to a fixed position, and it is difficult to determine the specific length of the smooth surface and the HDMI interface. There is a problem that the smooth surface is also blocked by the display device. By sliding the smooth surface, different positions on the optical cable can be adjusted to cope with the interface plugging scene of display devices of different sizes, and the application range of the smooth surface is improved.

[0020] 4. When the length of the handheld optical cable position is long, the optical cable is easy to bend, causing unloading, and it is difficult to insert the interface. To solve this problem, a hard sleeve is arranged around the sheath to provide additional support for the optical cable, avoid the HDMI interface from sagging, and make the HDMI interface easier to align. The hard sleeve directly transmits the external force applied by the hand to the HDMI interface, and even when the force application position is far from the HDMI interface, the HDMI interface can still be plugged in. By setting the smooth surface on the hard sleeve, the smooth surface can change the observation position with the movement of the hard sleeve, which reduces the operation steps of plugging compared to the case where the smooth surface and the hard sleeve are separately arranged.

[0021] 5. The connection between the first sleeve and the second sleeve is set to be a damping rotation, so that the first sleeve and the second sleeve can change the angle and maintain the angle, which is convenient for holding and plugging the interface with one hand, increases the stability of the HDMI line during use, and prevents the cable from falling off or being damaged due to shaking or collision in the case of frequent movement or adjustment of the display device position.

In addition, the terms "first", "second" and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0038] Embodiment one: see Figures 1-3 As shown in the figure, the embodiment provides an optical and electrical hybrid cable for converting Type-C signal to HDMI signal, which comprises an HDMI interface 1, a USB Type-C interface 2 and an optical cable 3. The USB Type-C interface 2 is connected to one end of the optical cable 3, and the HDMI interface 1 is connected to the other end of the optical cable 3. The cable core part of the optical cable 3 contains a plurality of optical fibers and copper wires. The optical fibers are used to transmit optical signals, and the copper wires are used to transmit power signals, control signals and other electrical signals. The optical cable 3 is provided with a sheath 31 around the optical fibers and copper wires. The sheath 31 is made of high-strength and corrosion-resistant material, which can effectively protect the cable core part from damage by the external environment. The shape of the sheath 31 can be set as cylindrical or flat. The sheath 31 is provided with a smooth surface 4 that can produce mirror reflection. By observing the interface position through the smooth surface 4, the process of plugging the interface is easier. The smooth surface 4 includes but is not limited to a plane mirror, an aluminum foil reflective film, which can be set to single-sided reflection or double-sided reflection. In this embodiment, the setting method of the smooth surface 4 is not limited. When the smooth surface 4 is used, it can be combined with bending, folding and moving the optical cable 3 to align the smooth surface 4 with the interface position on the backboard of the display device, so as to facilitate the observation of the state during the plugging of the interface.

[0039] Preferably, for example Figure 1 As shown in the figure, the smooth surface 4 is arranged perpendicular to the axis of the optical cable 3, and the smooth surface is provided with double-sided reflection to facilitate direct observation of the interface to be plugged. A clamping groove perpendicular to the axis is arranged on the sheath 31, and the smooth surface 4 is embedded in the clamping groove. The length of the optical cable 3 between the smooth surface 4 and the HDMI interface 1 is greater than the distance between the HDMI interface 1 on the backboard and the edge of the backboard, so that the smooth surface 4 is difficult to be blocked by the display device. When in use, one hand of the user operates the interface plugging, and the other hand holds the smooth surface outside the frame of the display device to adjust the reflection surface towards the interface on the backboard. This way is simple to operate, and the optical cable 3 itself can be bent to assist in adjustment, so as to facilitate the observation of the position of the interface and whether it is aligned.

[0040] Preferably, a support strip 5 is arranged on the sheath 31, and the end of the support strip 5 away from the sheath 31 is rotationally connected with the smooth surface 4. Since the orientation of the smooth surface 4 can be adjusted by bending and moving the optical cable 3, the setting method of the smooth surface 4 and the support strip 5 is not limited in this embodiment. The smooth surface 4 can be arranged perpendicular to the axis of the optical cable 3 to facilitate the observation of the plugging position, or can be arranged parallel to the axis of the optical cable 3 to increase the passability of the smooth surface 4. Optionally, for example Figure 2As shown, the support bar 5 can be an elastic bar, and the smooth surface 4 rotates around the support bar 5 by elastic potential energy, so as to be parallel to the optical cable 3 and improve the passability of the smooth surface 4. Alternatively, for example Figure 3 As shown, the support bar 5 is provided with a spherical groove at an end away from the optical cable 3, and the opening of the spherical groove is a circle with a radius smaller than that of the spherical groove. A rotating ball matched with the inner cavity of the groove is arranged in the spherical groove, and the rotating ball is connected with the smooth surface 4. The material of the support bar 5 is preferably an elastic material, so as to facilitate the insertion of the rotating ball into the inner cavity of the groove. The smooth surface 4 rotates by the rotating ball. In this way, the smooth surface 4 can be rotated to an angle convenient for observing the interface and kept at the angle. When the smooth surface 4 rotates and is parallel to the optical cable 3, not only the passability of the optical cable 3 between the backboard and the wall is improved, so that the smooth surface 4 is as close as possible to the interface position for convenient observation, but also the space occupation is reduced, which is beneficial to the storage of the optical cable 3.

[0041] Embodiment two: for example Figures 4-5 As shown, the embodiment provides an optical and electrical hybrid cable for converting Type-C signal into HDMI signal, the sheath 31 is provided with a first sliding groove 6, the first sliding groove 6 is provided with a matched first sliding block 7, the first sliding block 7 is connected with the smooth surface 4 at an end away from the optical cable 3, and the first sliding block 7 slides along the axial line direction of the optical cable 3, so that the smooth surface 4 can be moved to a position convenient for observing the interface plugging. Due to different sizes or different interface position designs of display devices, the length of the optical cable 3 blocked by the display device is different. Therefore, if a fixed position is arranged for the smooth surface 4, it is difficult to determine the length of the smooth surface 4 away from the HDMI interface 1, and the smooth surface 4 is also blocked by the display device. By sliding the smooth surface 4, different positions of the smooth surface 4 on the optical cable 3 can be adjusted to cope with the interface plugging scene of display devices of different sizes, and the application range of the smooth surface 4 is improved.

[0042] Alternatively, for example Figure 4 As shown, the first sliding groove 6 is a convex strip. The convex strip is arranged on the surface of the sheath 31 from one end to the other end of the optical cable 3, and the convex strip is parallel to the axial line of the optical cable 3. The convex strip extends to both sides perpendicular to the convex strip at an end away from the optical cable 3. The first sliding block 7 is a through groove matched with the convex strip. The smooth surface 4 is connected with the through groove at an end away from the optical cable 3 and moves along the convex strip with the through groove.

[0043] Preferably, for example Figure 5As shown, the first slide 6 is the optical cable 3. The first slider is a first ferrule, which is arranged around the sheath 31. The optical smooth surface 4 is connected with the first ferrule. The optical smooth surface 4 moves along the optical cable 3 with the first ferrule. This scheme has simple structure and does not need to change the shape of the optical cable 3. Further, the first ferrule is made of elastic material and has a radius less than or equal to that of the sheath, so that it can be tightened on the sheath. In use, the user stretches the first ferrule to form a gap between the first ferrule and the optical cable 3, so as to slide the optical cable 3. After the optical smooth surface 4 is moved to a position convenient for observation, the first ferrule is tightened, so that the first ferrule and the optical cable 3 reduce relative displacement.

[0044] Embodiment three: This embodiment is based on embodiment two, for example Figures 6-10 As shown, a slidable hard sleeve 8 is arranged around the sheath 31. The optical fiber wire and the copper wire of the optical cable 3 have small diameters, and the sheath 31 is usually made of plastic. When the length of the position of the HDMI interface 1 away from the hand is long, the support strength of the optical cable 3 itself is difficult to resist the weight of the optical cable 3, so that the HDMI interface 1 is difficult to be aligned with the interface on the back plate of the display device. At the same time, in order to improve the connection stability of the interface, the HDMI interface 1 is internally provided with a protrusion, and the electric core pin is designed with high-strength metal, so that when the interface is inserted, the user usually needs to directly apply external force to the HDMI interface 1. When the length of the position of the handheld optical cable 3 is long, the optical cable 3 is easy to bend, causing unloading, and it is difficult to insert the interface. The hard sleeve 8 can provide additional support for the optical cable 3, avoid the HDMI interface 1 from drooping, and make the HDMI interface 1 easier to align.

[0045] Further, the diameter of the hard sleeve 8 is less than the width of the flat surface of the HDMI interface 1, so that the hard sleeve 8 can abut against one end of the HDMI interface 1 close to the optical cable 3. The external force applied by the hand is directly transmitted to the HDMI interface 1 through the hard sleeve 8, so that the HDMI interface 1 is inserted for a long distance.

[0046] Preferably, for example Figure 6 As shown, the optical smooth surface 4 is arranged on the hard sleeve 8.

[0047] Preferably, the support strip 5 is arranged on the hard sleeve 8.

[0048] Preferably, the first slide 6 is arranged on the hard sleeve 8.

[0049] For a display device such as a television, the weight and size are large, and there is a situation that the television is hung on the wall, and it is difficult to move. And the gap between the back plate of the television and the wall is small, and the arm is difficult to move freely when plugging the HDMI interface 1. The smooth surface 4 is arranged on the hard sleeve 8, and the observation position can be changed with the movement of the hard sleeve 8, compared with the case where the smooth surface 4 and the hard sleeve 8 are arranged separately, the operation steps of plugging are reduced.

[0050] Further, for example Figure 7 As shown, the hard sleeve 8 is provided with a separable connection or opening 9 along the axial direction, so that the hard sleeve 8 can be separated from the optical cable 3. The back plate of the display device is usually provided with multiple interfaces to realize the connection of multiple input devices. Multiple optical cables 3 provided with the hard sleeve 8 will occupy a large wiring space, making it difficult to comb the optical cable 3. The optical cable 3 inserted into the interface first will further reduce the operation space, making it difficult for other optical cables 3 or connection lines to have a suitable space for plugging operation. At the same time, it also increases the purchase cost of the optical cable 3 for consumers. By providing a separable connection for the hard sleeve 8, consumers only need to purchase one optical cable 3 provided with the hard sleeve 8, which can be used for other optical cables 3 or connection lines without the hard sleeve 8. At the same time, after the interface is inserted, the hard sleeve 8 can be separated from the optical cable 3 or the connection line, which is beneficial to increase the space for plugging operation in the case of multiple connection lines.

[0051] Embodiment four: based on embodiment three, for example Figures 8-10 As shown, the hard sleeve 8 includes a first sleeve 81 and a second sleeve 82. The first sleeve 81 and the second sleeve 82 are rotatably connected, and the axis of the rotating shaft 14 is perpendicular to the optical cable 3, so that the first sleeve 81 and the second sleeve 82 rotate in the same plane. The rotating shaft 14 and the hard sleeve 8 are provided with a first channel 16, and the optical cable 3 passes through the first channel 16. Most of the current display devices are provided with a recess on the back plate, and the HDMI interface 1 is arranged on the inner edge of the recess. The step formed by the edge of the recess will cause the sleeve to be in an inclined state when plugging the HDMI interface 1, and will exert a lateral force on the HDMI interface 1, which is easy to damage the HDMI interface 1. By providing rotatable connection, the angle of the first sleeve 81 and the second sleeve 82 is changed, and the interface of the first sleeve 81 or the second sleeve 82 is plugged in a straight line, which increases the service life of the interface.

[0052] Optionally, for example Figure 8 And Figure 9As shown, the first sleeve 81 is provided with a first connecting plate 11 at one end close to the second sleeve 82. The second sleeve 82 is provided with a second connecting plate 12 at one end close to the first sleeve 81. The first connecting plate 11 and the second connecting plate 12 are oppositely arranged and connected by a rotating shaft 14. The rotating shaft 14 is arranged at the second connecting plate 12, and its axis is coincident with the axis of the second connecting plate 12. The first connecting plate 11 is provided with a base 15 matched with the rotating shaft 14.

[0053] Optionally, for example Figure 10 As shown, the first sleeve 81 is provided with a pair of first connecting plates 11 at one end close to the second sleeve 82, and the first connecting plates 11 are arranged at both sides of the axis of the first sleeve 81. The opposite side of the first connecting plate 11 is provided with a base 15, and optionally, the base 15 and the side of the first connecting plate 11 facing the second sleeve 82 are inscribed. The second connecting plate 12 is arranged at one end of the second sleeve 82 close to the first sleeve 81. The second connecting plate 12 is provided with the rotating shaft 14 at both sides, and the rotating shaft 14 and the side of the second connecting plate 12 facing the first sleeve 81 are inscribed. The rotating shaft 14 is matched with the base 15, so that the first sleeve 81 and the second sleeve 82 rotate.

[0054] Although the material of the optical fiber is also elastic and can resist stress caused by bending to a certain extent, if the maximum bending angle and / or the maximum bending radius of the optical fiber are exceeded, the optical signal will be seriously lost, which will cause difficulty in cable wiring after the HDMI interface 1 is connected. Therefore, the first sleeve 81 and the second sleeve 82 need to be rotated away from the optical cable 3 when in use, and the arc surface of the rotating shaft 14 is used to make the optical fiber bend in a circular arc shape, so as to reduce the bending situation of a right angle or an acute angle, which is beneficial to improve the photoelectric transmission efficiency. However, in this way, the direction of rotation of the sleeve around the rotating shaft 14 is difficult to change. If it is necessary to adjust the direction of rotation around the rotating shaft 14, the hard sleeve 8 needs to be rotated around the optical cable 3, and the rotating shaft 14 needs to be directed to the direction to be rotated, which increases the operation difficulty of wiring.

[0055] Therefore, preferably, for example Figures 8-10 As shown, a first arc surface 13 is arranged between the axis of the first sleeve 81 and the edge of the first connecting plate 11, or between the axis of the second sleeve 82 and the edge of the second connecting plate 12. The first arc surface 13 and the rotating shaft 14 form the first channel 16. The first arc surface 13 and the arc surface of the rotating shaft 14 are opposite, so that when the hard sleeve 8 is arbitrarily rotated around the rotating shaft 14, the optical cable 3 realizes circular arc bending by using the first arc surface or the arc surface of the rotating shaft 14, which is beneficial to improve the wiring efficiency.

[0056] Further, the rotating shaft 14 is a damping rotating shaft 14. The connection between the first sleeve 81 and the second sleeve 82 is set as a damping rotation, so that the first sleeve 81 and the second sleeve 82 can change the angle and keep the angle, facilitate holding, realize single-handed plugging of the interface, increase the stability of the HDMI cable in use, and prevent the cable from falling off or being damaged due to shaking or collision in the case of frequent movement or adjustment of the display device position.

[0057] Embodiment five: the optical and electrical hybrid cable provided by the embodiment converts Type-C signal into HDMI signal, for example Figure 11 As shown in the figure, the optical cable 3 is flat, and the smooth surface 4 is arranged on the flat surface of the sheath 31. The sheath 31 of the optical cable 3 is arranged as flat, which provides space for the arrangement of the smooth surface 4. The smooth surface 4 for observing the interface position is arranged by using the plane of the optical cable 3 itself, which reduces the space occupied by the optical cable 3. The smooth surface 4 includes but is not limited to an aluminized mirror surface reflection film and a silver-coated mirror surface reflection film.

[0058] Preferably, for example Figure 11 As shown in the figure, the smooth surface 4 is arranged detachably around the sheath 31, and the smooth surface 4 is arranged on the side with the narrowest width of the sheath 31. Starting from one end of the optical cable 3, the detachable connection is arranged along the axial line of the optical cable 3, and the other end of the optical cable 3 is the end point. The smooth surface 4 is separated from the sheath 31 by the detachable connection, and is combined with the smooth surface 4 on the flat surface of the other side of the sheath 31 to expand the reflection area for observing the interface. After the interface is inserted, the smooth surface 4 can be attached back to the original position to realize repeated use.

[0059] Further, a plurality of detachable connections are arranged on the smooth surface 4 perpendicular to the axial line of the optical cable 3, so that the smooth surface 4 can be separated from the sheath 31 at a position convenient for observing the interface position.

[0060] Further, a plurality of the smooth surfaces 4 are arranged on the flat surface. After being used for many times, the smooth surface 4 may be difficult to attach repeatedly, and many times of use may also cause the smooth surface 4 to be dirty and wrinkled, reducing the effect of clear observation. The smooth surface 4 that is difficult to observe is discarded, and the next layer of the smooth surface 4 can continue to realize the function of observing the interface.

Although the utility model has been described in detail with reference to the above-described various embodiments, the utility model is not limited to the above-described specific embodiments, and therefore any modification or equivalent replacement of the utility model is allowed.
