Description

Technical Field

[0001] The present invention belongs to the technical field of transmission lines, and particularly relates to an HDMI video transmission line that is convenient for installation. Background Art

[0002] HDMI video transmission line is the abbreviation of High-Definition Multimedia Interface line, which can transmit uncompressed high-definition video and multi-channel audio data with high quality, and the highest data transmission speed is 5Gbps. At the same time, there is no need to perform digital-to-analog or analog-to-digital conversion before signal transmission, which can ensure the transmission of the highest quality audio and video signals. In the process of implementing the present invention, the inventor found that there are at least the following problems in the prior art: For a high-quality HDMI video transmission line that requires high quality, it is generally thicker than a normal HDMI video transmission line. For such a thicker high-quality HDMI video transmission line, its bendability is greatly reduced, that is, what is often called "the wire is too hard" in the traditional sense. Then, when docking two HDMI slots in a relatively narrow environment with a thicker high-quality HDMI video transmission line, it is inevitable to bend or twist to a large extent to accurately insert it into the corresponding HDMI slot. Especially when the thicker high-quality HDMI video transmission line becomes shorter in order to adapt to a relatively narrow environment, the bending or twisting action of bending or twisting to a large extent to accurately insert it into the corresponding HDMI slot will be more difficult to complete; When a shorter and thicker high-quality HDMI video transmission line often bends or twists to a large extent to adapt to a relatively narrow environment, it is very easy to cause irreversible damage to the transmission wires in the high-quality HDMI video transmission line, affecting the service life, and even being damaged and unable to perform normal signal transmission. In addition, when a high-quality HDMI video transmission line is often replaced and re-plugged into the HDMI slot, the frequent bending of the high-quality HDMI video transmission line is very likely to cause the phenomenon of "memory bending" in the bending direction of the high-quality HDMI video transmission line. The next time the high-quality HDMI video transmission line is replaced and re-plugged into the HDMI slot, perhaps the bending direction of the high-quality HDMI video transmission line in the "memory bending" state is not suitable for the HDMI slot at this time, and when the high-quality HDMI video transmission line in the "memory bending" state is forcibly bent in the direction opposite to the "memory bending" direction, it is very easy to damage the transmission wires, and even damage the transmission wires and unable to perform normal signal transmission.

[0003] The present invention designs an HDMI video transmission line that is convenient for installation to solve the above problems. Summary of the Invention

The design of the A fixed support plate, B fixed support plate and connecting bolts is to facilitate the assembly or disassembly of the A semi-fixed sleeve and the B semi-fixed sleeve.

[0010] As a further improvement of the present technology, a B outer ring with a B ring groove on the inner ring surface is fixedly installed on the inner surface of the fixed sleeve, and a B card slot is opened on the inner groove surface of the B ring groove; a B inner ring with a B card end is fixedly installed on the outer surface of the fixed column; the B inner ring is located in the B ring groove of the B outer ring, and the B card end is located in the B card slot. The design of the B outer ring, B inner ring and B card end facilitates the fixed connection between the fixed column and the fixed sleeve, ensuring that the transmission of the fixed metal sheet installed on the fixed column through the fixed column, B inner ring, B card end and B outer ring can move synchronously with the fixed sleeve, meeting the operation design requirements of the present invention.

[0011] As a further improvement of the present technology, two A rotating support plates are symmetrically provided on the outer surface of the A semi-rotating sleeve, and two B rotating support plates are symmetrically provided on the outer surface of the B semi-rotating sleeve; the two A rotating support plates and the two B rotating support plates correspond to each other one by one and are connected by connecting bolts. The design of the A rotating support plate, B rotating support plate and connecting bolts is to facilitate the assembly or disassembly of the A semi-rotating sleeve and the B semi-rotating sleeve.

[0012] As a further improvement of the present technology, an A outer ring with an A ring groove on the inner ring surface is fixedly installed on the inner surface of the rotating sleeve, and an A card slot is opened on the inner groove surface of the A ring groove; an A inner ring with an A card end is fixedly installed on the outer peripheral surface formed by the 20 isolation strips; the A inner ring is located in the A ring groove of the A outer ring, and the A card end is located in the A card slot. The design of the A outer ring, A inner ring and A card end facilitates the fixed connection between the rotating column and the rotating sleeve, ensuring that the transmission of the rotating metal sheet installed on the rotating column through the rotating column, isolation strips, A inner ring, A card end and A outer ring can move synchronously with the rotating sleeve, meeting the operation design requirements of the present invention.

[0013] As a further improvement of the present technology, a sealing ring groove is opened on the inner surface of the rotating sleeve, and a ring-shaped seal is fixedly installed in the sealing ring groove; the inner ring surface of the ring-shaped seal is attached to the outer circular surface of the above-mentioned protruding end. The ring-shaped seal adopts the prior art.

[0014] As a further improvement of the present technology, one ends of the 20 transmission wires at one end of the transmission line in the A male head are respectively connected to the 20 fixed metal sheets in the A male head by soldering through 20 B wires; in the A male head, one ends of the 19 rotating metal sheets away from the contact are respectively connected to 19 wiring holes by soldering through 19 A wires.

[0017] As a further improvement of this technology, one end of the spring is connected to the slider, and the other end is connected to the groove surface of the corresponding slide; the ceramic polymer material is ceramic silicone rubber. The advantages of using ceramic silicone rubber are: ceramic silicone rubber has excellent fire resistance, flame retardancy, low smoke, non-toxicity and other characteristics, the extrusion molding process is simple, and the residue after combustion is a hard ceramic shell. The hard shell does not melt or drip in a fire environment. It can pass the line integrity test specified in GB / T19216.21-2003 at 950℃~1000℃, fire for 90min, and cooling for 15min. It is suitable for any place that requires fire protection, and plays a solid protective role in ensuring smooth power transmission in the event of a fire. Ceramic silicone rubber products have no special requirements for equipment, and the processing technology is simple. They can be produced using traditional silicone rubber processing equipment. Compared with the current fire-resistant wire and cable production process, they have higher production efficiency and can reduce production energy consumption and save costs.

[0018] The traditional transmission line has five groups of main lines and four groups of signal lines, each group of main lines has two core wires and one ground wire; the five groups of main lines and four groups of signal lines are 19 transmission wires in total. The transmission line of the present invention has five groups of main lines and five groups of signal lines, each group of main lines has two core wires and one ground wire; the five groups of main lines and five groups of signal lines are 20 transmission wires in total, but the HDMI interface of the interface socket of the A male head and the B male head of the present invention has 19 receiving signal paths, so the HDMI interface of the A male head and the B male head is exactly the same as the traditional HDMI interface. The reason why the transmission line of the present invention has one more signal line than the traditional transmission line is to facilitate the normal signal output of the A male head and the B male head of the present invention after performing the same angle rotation operation.

[0019] The interface seat, the wiring board, the HDMI interface, and the electrical connection between the wiring hole and the HDMI interface of the present invention can all adopt the existing technology.

[0020] Compared with the traditional HDMI video transmission line technology, the effective effects of the present invention are:

[0021] 1. When docking two HDMI slots in a relatively narrow environment, for the HDMI video transmission line of the present invention, only by rotating the male connector A and the male connector B in the present invention by the same angle can the HDMI interfaces in the male connector A and the male connector B be easily aligned with the HDMI slots to a great extent and then inserted into the corresponding HDMI slots. Then, the HDMI video transmission line of the present invention can be smoothly inserted into the corresponding HDMI slots under the condition of very small bending or twisting, avoiding the need for the HDMI video transmission line to be bent or twisted to a large extent to accurately insert into the corresponding HDMI slots, thereby avoiding damage or breakage of the transmission wires in the HDMI video transmission line caused by frequent large - degree bending or twisting of the transmission wires, achieving the effect of protecting the HDMI video transmission line and extending its service life.

[0022] 2. Since the male connector A and the male connector B in the present invention can be rotated, when the bending direction of the high - quality HDMI video transmission line in the "memory - bending" state is not suitable for the HDMI slot at this time, there is no need to force the high - quality HDMI video transmission line in the "memory - bending" state to be bent in the direction opposite to the "memory - bending" direction to insert the HDMI interface into the HDMI slot, avoiding damage to the HDMI video transmission line.

[0023] 3. The design advantages of the slider, spring, V - shaped guide rail and V - shaped strip are that they can avoid the phenomenon of poor information transmission caused by inaccurate rotation operation of the male connector A or the male connector B by the user when inserted into the HDMI slot, ensuring that the present invention can be used only after accurate rotation operation, and further ensuring that the present invention can transmit signals normally.

[0024] 4. The male connector A and the male connector B of the present invention are small in volume and simple in structure, and have good use effects.

[0025] 5. The male connector A and the male connector B of the present invention can be rotationally adjusted relative to the transmission line to achieve normal signal transmission. When a traditional HDMI video transmission line also realizes a rotatable male connector to adapt to the position of the HDMI socket, generally two solutions are adopted: First, multiple wires inside the transmission line are welded to the corresponding contacts of the male connector. At the positions of the multiple wires, the main line, signal line, and ground line have sufficient slack. During the rotation process, the slack of the wires is used to ensure that there is no great extrusion force between the wires, ensuring normal signal transmission. Second, to ensure that the male connector can rotate relative to the transmission line, it is necessary to consider that the 19 contacts of the male connector and the 19 wires of the transmission line always maintain electrical connection during the rotation process. The rotation of the male connector will cause the contacts of the male connector to change their positions relative to the wires to which they are electrically connected. Making the male connector contacts or wires into metal sheets extending in the rotation direction can achieve the purpose of sliding electrical connection between the contacts and the metal sheets during the rotation process. This method requires 19 metal sheets, and the spatial distribution of the 19 groups of metal sheets and the corresponding contacts will be extremely complex, and the occupied space will be greatly increased. Therefore, the traditional two methods require sufficient installation space, resulting in the bulkiness of the HDMI video transmission line, which is not conducive to the production and assembly of the HDMI video transmission line.

[0049] As Figure 9 shown, 20 transmission wires at one end of the transmission line 1 located in the B male head 5 are respectively connected to 20 fixed metal sheets 29 in the B male head 5 by soldering through 20 B wires 61; in the B male head 5, one ends of 19 rotating metal sheets 39 away from the contact 51 are respectively connected to 19 wiring holes 9 by soldering through 19 A wires 60.

[0050] The limiting end 13 of the above-mentioned V-shaped plate is always parallel to the HDMI interface 6; the insulating layers of the above-mentioned 20 transmission wires all adopt ceramicized polymer materials.

[0051] As Figure 7As shown, one end of the spring 15 is connected to the slider 14, and the other end is connected to the groove surface of the corresponding slide 16; the ceramic polymer material is ceramic silicone rubber. The advantages of using ceramic silicone rubber are: ceramic silicone rubber has excellent fire resistance, flame retardancy, low smoke, non-toxicity and other characteristics, the extrusion molding process is simple, and the residue after combustion is a hard ceramic shell, which does not melt or drip in a fire environment. It can pass the line integrity test specified in GB / T19216.21-2003 at 950℃~1000℃, fire for 90min, and cooling for 15min. It is suitable for any place that requires fire protection, and plays a solid protective role in ensuring smooth power transmission in the event of a fire. Ceramic silicone rubber products have no special requirements for equipment, and the processing technology is simple. They can be produced using traditional silicone rubber processing equipment. Compared with the current fire-resistant wire and cable production process, they have higher production efficiency and can reduce production energy consumption and save costs.

[0052] The traditional transmission line 1 has five groups of main lines 2 and four groups of signal lines 3, each group of main lines 2 has two core lines and one ground line; the five groups of main lines 2 and the four groups of signal lines 3 are 19 transmission conductors in total. The transmission line 1 of the present invention has five groups of main lines 2 and five groups of signal lines 3, each group of main lines 2 has two core lines and one ground line; the five groups of main lines 2 and the five groups of signal lines 3 are 20 transmission conductors in total, but the HDMI interface 6 of the interface socket 7 of the A male connector 4 and the B male connector 5 of the present invention has 19 receiving signal paths, so the HDMI interface 6 of the A male connector 4 and the B male connector 5 is exactly the same as the traditional HDMI interface 6. The reason why the transmission line 1 of the present invention has one more signal line 3 than the traditional transmission line 1 is to facilitate the normal signal output of the A male connector 4 and the B male connector 5 of the present invention after performing the same angle rotation operation.

[0053] The interface seat 7, the wiring board 8, the HDMI interface 6, and the electrical connection between the wiring hole 9 and the HDMI interface 6 of the present invention can all adopt existing technologies.

[0054] An embodiment of the present invention: in the initial state, when the corresponding HDMI slot is not inserted, the fastening bolt 34 and the outer ring surface of the convex ring are frictionally limited to ensure that the rotating sleeve and the fixed sleeve are relatively fixed, and the contacts 51 of the 19 rotating metal sheets 39 are electrically contacted with 19 of the 20 fixed metal sheets 29; the end of the V-shaped bar 10 away from the limiting end 13 corresponds to the position of a slider 14, the limiting end 13 passes through the V-shaped guide rail 12 and the limiting end 13 is located at the HDMI interface 6; one end of the V-shaped guide rail 12 is aligned with the position of an identification strip 19.

[0055] In actual use, in order to minimize the bending or twisting of a high-quality HDMI video transmission cable as much as possible, only by rotating the male A connector 4 and the male B connector 5 in the present invention by the same angle, it is very easy to align the HDMI interfaces 6 in the male A connector 4 and the male B connector 5 with the HDMI slots and then insert them into the corresponding HDMI slots. The rotation operations for the male A connector 4 and the male B connector 5 are exactly the same. Taking the rotation operation of one male A connector 4 as an example:

[0056] Assume that when not inserted into the corresponding HDMI slot in the initial state, the number of the identification strip 19 aligned with one end of the V-shaped guide rail 12 is (A), then the other four identification strips 19 are (B), (C), (D), and (E) in clockwise order; as Figure 11 shown, the five main lines 2 and the five signal lines 3 form five groups of combined lines one by one. Each combined line has one main line 2 and one signal line 3, that is, each combined line has 4 transmission wires; the five groups of combined lines are the (A) combined line, the (B) combined line, the (C) combined line, the (D) combined line, and the (E) combined line; as Figure 11As shown, 20 fixed metal sheets 29 are grouped into fixed combined sheets in groups of 4 along the clockwise direction, that is, there are five groups of fixed combined sheets. The five groups of fixed combined sheets are, in clockwise order, (A) fixed combined sheet, (B) fixed combined sheet, (C) fixed combined sheet, (D) fixed combined sheet, and (E) fixed combined sheet; the (A) fixed combined sheet corresponds to the (A) identification strip 19, the (B) fixed combined sheet corresponds to the (B) identification strip 19, the (C) fixed combined sheet corresponds to the (C) identification strip 19, the (D) fixed combined sheet corresponds to the (D) identification strip 19, and the (E) fixed combined sheet corresponds to the (E) identification strip 19; the (A) fixed combined sheet is always electrically connected to the (A) combined line correspondingly, the (B) fixed combined sheet is always electrically connected to the (B) combined line correspondingly, the (C) fixed combined sheet is always electrically connected to the (C) combined line correspondingly, the (D) fixed combined sheet is always electrically connected to the (D) combined line correspondingly, and the (E) fixed combined sheet is always electrically connected to the (E) combined line correspondingly; 19 rotating metal sheets 39 are divided into five groups of rotating combined sheets in sequence along the clockwise direction. The five groups of rotating combined sheets are, in sequence, (A) rotating combined sheet, (B) rotating combined sheet, (C) rotating combined sheet, (D) rotating combined sheet, and (E) rotating combined sheet. The (A) rotating combined sheet, (B) rotating combined sheet, (C) rotating combined sheet, and (D) rotating combined sheet each have 4 rotating metal sheets 39, while the (E) rotating combined sheet has 3 metal sheets. Assume that at this time, the (A) rotating combined sheet is electrically connected to the (A) fixed combined sheet, the (B) rotating combined sheet is electrically connected to the (B) fixed combined sheet, the (C) rotating combined sheet is electrically connected to the (C) fixed combined sheet, the (D) rotating combined sheet is electrically connected to the (D) fixed combined sheet, and the (E) rotating combined sheet is electrically connected to the (E) fixed combined sheet. In this state, the signal transmission path in the A male head 4 is as follows: the (A) combined line is electrically transmitted to the (A) rotating combined sheet through the (A) fixed combined sheet, the (B) combined line is electrically transmitted to the (B) rotating combined sheet through the (B) fixed combined sheet, the (C) combined line is electrically transmitted to the (C) rotating combined sheet through the (C) fixed combined sheet, the (D) combined line is electrically transmitted to the (D) rotating combined sheet through the (D) fixed combined sheet, and the (E) combined line is electrically transmitted to the (E) rotating combined sheet through the (E) fixed combined sheet.

[0057] Loosen the fastening bolt 34 so that the fastening bolt 34 no longer frictionally limits the outer ring surface of the convex ring; while fixing the fixed sleeve by hand, rotate the rotating sleeve clockwise, and the rotating posts 38 and 19 rotating metal pieces 39 in the rotating sleeve move synchronously with the rotating sleeve; one end of the V-shaped guide rail 12 is disengaged from the alignment with the (A) identification strip 19; assume that when one end of the V-shaped guide rail 12 is aligned with the (C) identification strip 19, when the high-quality HDMI video transmission line is bent or twisted slightly, the HDMI interface 6 in the male A connector 4 can be easily aligned with the corresponding HDMI slot. Then, stop rotating the rotating sleeve, and the end of the V-shaped strip 10 away from the limiting end 13 corresponds to the position of the slider 14 at the (C) identification strip 19. Then, tighten the fastening bolt 34 so that the fastening bolt 34 frictionally limits the outer ring surface of the convex ring again. When the V-shaped guide rail 12 on the rotating sleeve rotates to the position of the (C) identification strip 19, the rotation amplitude of the 19 rotating metal pieces 39 just passes through 7 fixed metal pieces 29, and the contacts 51 on the 19 rotating metal pieces 39 are in electrical contact with 19 of the 20 fixed metal pieces 29 again. As Figure 12 shown, at this time, the (A) rotating combination piece is no longer electrically connected to the (A) fixed combination piece, but the (A) rotating combination piece is electrically connected to the (C) fixed combination piece; the (B) rotating combination piece is no longer electrically connected to the (B) fixed combination piece, but the (B) rotating combination piece is electrically connected to the (D) fixed combination piece; the (C) rotating combination piece is no longer electrically connected to the (C) fixed combination piece, but the (C) rotating combination piece is electrically connected to the (E) fixed combination piece; the (D) rotating combination piece is no longer electrically connected to the (D) fixed combination piece, but the (D) rotating combination piece is electrically connected to the (A) fixed combination piece; the (E) rotating combination piece is no longer electrically connected to the (E) fixed combination piece, but the (E) rotating combination piece is electrically connected to the (B) fixed combination piece. The signal transmission path in the male A connector 4 when the V-shaped guide rail 12 on the rotating sleeve rotates to the position of the (C) identification strip 19 is: the (A) combination wire is electrically transmitted to the (D) rotating combination piece through the (A) fixed combination piece, the (B) combination wire is electrically transmitted to the (E) rotating combination piece through the (B) fixed combination piece, the (C) combination wire is electrically transmitted to the (A) rotating combination piece through the (C) fixed combination piece, the (D) combination wire is electrically transmitted to the (B) rotating combination piece through the (D) fixed combination piece, and the (E) combination wire is electrically transmitted to the (C) rotating combination piece through the (E) fixed combination piece.

[0058] The initial state of the male B connector 5 must be the same as the initial state of the male A connector 4, that is, one end of the V-shaped guide rail 12 in the male B connector 5 is aligned with the position of the (A) identification strip 19 in the male B connector 5; the signal transmission path in the male B connector 5 is: the (A) combination wire is electrically transmitted to the (A) rotating combination piece through the (A) fixed combination piece, the (B) combination wire is electrically transmitted to the (B) rotating combination piece through the (B) fixed combination piece, the (C) combination wire is electrically transmitted to the (C) rotating combination piece through the (C) fixed combination piece, the (D) combination wire is electrically transmitted to the (D) rotating combination piece through the (D) fixed combination piece, and the (E) combination wire is electrically transmitted to the (E) rotating combination piece through the (E) fixed combination piece.

[0059] Similarly, when one end of the V-shaped guide rail 12 on the rotating sleeve of the B male connector 5 rotates to the position of the (C) identification strip 19, the signal transmission path of the B male connector 5 in this state is as follows: the (A) combined wire is electrically transmitted to the (D) rotating combined piece through the (A) fixed combined piece, the (B) combined wire is electrically transmitted to the (E) rotating combined piece through the (B) fixed combined piece, the (C) combined wire is electrically transmitted to the (A) rotating combined piece through the (C) fixed combined piece, the (D) combined wire is electrically transmitted to the (B) rotating combined piece through the (D) fixed combined piece, and the (E) combined wire is electrically transmitted to the (C) rotating combined piece through the (E) fixed combined piece.

[0060] In summary, it is not difficult to find that after the A male connector 4 and the B male connector 5 are rotated by the same angle, after the HDMI interface 6 receives the input signal and transmits the output signal through the HDMI video transmission line of the present invention, the signal points of the HDMI interface 6 of the A male connector 4 still correspond one by one to the signal points of the HDMI interface 6 of the B male connector 5, ensuring that the signal transmission between the A male connector 4 and the B male connector 5 is still exactly the same after the A male connector 4 and the B male connector 5 are rotated by the same angle. The HDMI video transmission line of the present invention can transmit signals completely normally. At the same time, the types of the 19 lines electrically connected between the HDMI interface 6 of the A male connector 4 and the HDMI interface 6 of the B male connector 5 do not change after the rotation adjustment, ensuring that the data line, the signal line 3, and the ground wire in the electrical connection play their respective roles and avoiding the wrong transmission of the ground wire transmitting signals.

[0061] When the HDMI interface 6 in the male connector A 4 or the male connector B 5 is inserted into the corresponding HDMI slot, when the end of the V-shaped strip 10 away from the limiting end 13 is completely aligned with the corresponding slider 14, the edge of the HDMI slot will exert a mutual extrusion effect on the limiting end 13 of the V-shaped strip 10. Then, the V-shaped strip 10 moves towards the corresponding slider 14, and the limiting end 13 enters the V-shaped guide rail 12. The end of the V-shaped strip 10 away from the limiting end 13 presses the corresponding slider 14 and enters the corresponding chute 16, and the spring 15 is compressed; when the HDMI interface 6 is completely inserted into the corresponding HDMI slot, the limiting end 13 completely enters the V-shaped guide rail 12 and does not affect the use of the HDMI video transmission line of the present invention; in addition, since the end of the V-shaped strip 10 away from the limiting end 13 enters the corresponding chute 16, it can also assist in the relative fixation between the rotating sleeve and the fixed sleeve, and better ensure the normal use of the present invention. If the end of the V-shaped strip 10 away from the limiting end 13 is not completely aligned with the corresponding slider 14, the edge of the HDMI slot will exert a mutual extrusion effect on the limiting end 13 of the V-shaped strip 10, and the V-shaped strip 10 moves towards the corresponding slider 14 and contacts the side surface of the fixed ring. Then, the V-shaped strip 10 cannot enter the corresponding chute 16 and cannot slide in the V-shaped guide rail 12. Furthermore, the HDMI interface 6 cannot be completely inserted into the corresponding HDMI slot. In this state, the HDMI video transmission line will not be able to transmit signals normally, reminding the user that the rotation operation of the male connector A 4 or the male connector B 5 is inaccurate, and avoiding the possible poor signal transmission of the HDMI video transmission line of the invention in the case of inaccurate rotation operation. The user can re-perform a micro-operation on the rotation of the male connector A 4 or the male connector B 5 to ensure that one end of the V-shaped strip 10 can enter the corresponding chute 16.

[0062] After the HDMI interface 6 in the male connector A 4 or the male connector B 5 of the present invention is pulled out from the corresponding HDMI slot, under the reset action of the spring 15, the corresponding slider 14 moves back to its original position, and the slider 14 pushes out the end of the V-shaped strip 10 that enters the chute 16, and the V-shaped strip 10 moves back to its original position.

[0063] Although the present invention is described in combination with the above embodiments, the present invention is not limited to the above embodiments, but only limited by the appended claims. Those of ordinary skill in the art can easily modify and change it, but do not depart from the essential concept and scope of the present invention.
