Technical Field
[0001] The present invention belongs to the technical field of connectors, and particularly relates to a plug housing and a high-frequency high-speed connector. Background Art
[0002] With the rapid development of technologies such as 5G communication, cloud computing, and big data, the data transmission volume between electronic devices has increased explosively, and the demand for high-speed and high-frequency data transmission has become more urgent. High-frequency high-speed connectors can achieve low-loss and high-fidelity data transmission in the high-frequency band, and can effectively improve the data processing and transmission efficiency of devices.
[0003] In the current applications of plug housings and high-frequency high-speed connectors, when the connector is inserted into the plug housing, the central conductor and the internal conductor of the connector rub against each other frequently. Long-term friction will continuously exacerbate the wear of the central conductor, seriously affecting the stable transmission of high-frequency high-speed data, resulting in problems such as data packet loss and a decrease in transmission rate. Summary of the Invention
[0004] In view of the problems in the prior art that in the applications of plug housings and high-frequency high-speed connectors, when the connector is inserted into the plug housing, the central conductor and the internal conductor of the connector rub against each other frequently. Long-term friction will continuously exacerbate the wear of the central conductor, seriously affecting the stable transmission of high-frequency high-speed data, resulting in data packet loss and a decrease in transmission rate, the present invention proposes the following technical solutions:
[0005] A plug housing includes a housing. Four springs are installed inside the housing. At the top of each of the four springs, a first inclined push rod is fixedly installed. The same ring plate is fixedly connected between two opposite first inclined push rods. Two outer conductors are fixedly installed inside the housing. Two insulators are fixedly installed inside the two outer conductors. At the top of both sides of each of the two insulators, at the position of the top of the first inclined push rod, a first elastic sheet is fixedly installed. The same insulating sheet is fixedly connected between the tops of two opposite first elastic sheets. At the bottom of both sides of the two outer conductors, at the position of the bottom of the first inclined push rod, a second inclined push rod is slidably installed. At the bottom of each of the four second inclined push rods, a second elastic sheet is fixedly installed. Two first V-shaped elastic sheets are fixedly installed on both sides inside the two outer conductors. The same extrusion bar is movably sleeved between two opposite first V-shaped elastic sheets. At the top of each of the four extrusion bars, at the position of the top of the second inclined push rod, an inclined push block is fixedly installed.
[0006] As a preference of the above technical solution, an outer joint is snap-fitted and installed inside the housing, and two conductors are arranged inside the outer joint.
[0007] The present invention further provides a high-frequency and high-speed connector, which includes the above-mentioned plug housing, and further includes two center conductors. The two center conductors are respectively located inside two insulators. A sliding rod is slidably installed inside each of the two center conductors. At the top position of the sliding rod inside each of the two center conductors, a third elastic piece is fixedly installed. At both sides of the inner top end of each of the two sliding rods, a limiting block is rotatably installed.
[0008] As a preference of the above technical solution, it is characterized in that at both ends of the inner part of each of the two center conductors at the bottom position of the sliding rod, a third inclined push rod is slidably installed. One side of each of the four third inclined push rods is in contact with one side of the corresponding first inclined push rod. A same second V-shaped elastic piece is fixedly connected between the two opposite third inclined push rods.
[0009] As a preference of the above technical solution, the edges of the limiting blocks are all arc-shaped. When the two opposite limiting blocks are parallel to each other, the maximum distance between the two ends of these two limiting blocks is greater than the diameter of the center conductor.
[0010] As a preference of the above technical solution, inclined angles are provided at the top ends of the third inclined push rods. The horizontal distance from the top ends of the third inclined push rods to the third elastic piece gradually increases in the direction of the outer surface of the center conductor. A slideway is provided at the bottom end of the sliding rod, and the inner wall of the slideway is in contact with the top end of the third inclined push rod.
[0011] As a preference of the above technical solution, chutes are provided at both sides of the top end of the center conductor. The horizontal distance from the bottom end of the chute to the third elastic piece gradually becomes larger in the direction of the center of the center conductor.
[0012] As a preference of the above technical solution, an inclined angle is provided on the opposite side of the push block and the second inclined push rod. The horizontal distance from one side of the push block to the center conductor gradually becomes larger in the direction of the spring. A notch is provided at the top end of the second inclined push rod, and the notch is in contact with the inclined angle.
[0013] As a preference of the above technical solution, inclined cutting surfaces are provided on one side of the third inclined push rod and one side of the first inclined push rod. The two inclined cutting surfaces are in contact with each other. Among them, the horizontal distance from the inclined cutting surface of the third inclined push rod to the center conductor gradually becomes smaller in the direction of the third elastic piece.
[0014] The beneficial effects of the present invention are as follows:
[0015] (1) Through the convex structure at the front end of the center conductor, a certain interval is formed between the outer joint conductor and the center conductor, avoiding direct contact and frequent friction between the two during the plugging and unplugging process, and can significantly reduce the wear of the center conductor caused by friction, and extend the service life of the center conductor;
[0016] (2) When the central conductor enters the deepest part of the conductor through the release structure, the convex structure retracts into the central conductor, and at the same time presses the outer surface of the conductor, so that the inner surface of the conductor is closely attached to the outer surface of the central conductor, ensuring the continuity and stability of signal transmission.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0026] Embodiment 1: The present invention provides a plug housing, as Figures 1 to 2As shown in the figure, it includes a housing 1. Inside the housing 1, four springs 2 are installed. At the top of each of the four springs 2, a first inclined push rod 3 is fixedly installed. Between the two opposite first inclined push rods 3, the same ring plate 4 is fixedly connected. Inside the housing 1, two outer conductors 5 are fixedly installed. Inside the two outer conductors 5, two insulators 6 are fixedly installed. At both sides of the top of the two insulators 6 at the position of the top of the first inclined push rod 3, first elastic pieces 7 are fixedly installed. At the top of the two opposite first elastic pieces 7, the same insulating piece 8 is fixedly connected. Inside the two outer conductors 5 on both sides at the position of the bottom of the first inclined push rod 3, second inclined push rods 9 are slidably installed. At the bottom of each of the four second inclined push rods 9, second elastic pieces 10 are fixedly installed. On both sides inside the two outer conductors 5, two first V-shaped elastic pieces 11 are fixedly installed. Between the two opposite first V-shaped elastic pieces 11, the same extrusion bar 12 is movably sleeved. On one side of each of the four extrusion bars 12 at the position of the top of the second inclined push rod 9, inclined push blocks 13 are fixedly installed.
[0027] As Figure 1 and Figure 2 shown in the figure, an outer joint 14 is snap-fitted and installed inside the housing 1. Two conductors 15 are arranged inside the outer joint 14. By inserting the outer joint 14 into the housing 1, the housing 1 fixes the outer joint 14 to ensure the stability of the connection of the outer joint 14.
[0028] Embodiment 2
[0029] The present invention also provides a high-frequency and high-speed connector. As Figures 3 to 7 shown in the figure, it includes the above-mentioned plug housing, and also includes two center conductors 16. The two center conductors 16 are respectively located inside the two insulators 6. Inside the two center conductors 16, sliding rods 17 are slidably installed. At the position of the top of the sliding rods 17 inside the two center conductors 16, third elastic pieces 18 are fixedly installed. On both sides of the top inside the two sliding rods 17, limit blocks 19 are rotatably installed.
[0030] As Figure 4 and Figure 7 shown in the figure, at both ends inside the two center conductors 16 at the position of the bottom of the sliding rods 17, third inclined push rods 20 are slidably installed. On one side of each of the four third inclined push rods 20, it is in contact with one side of the corresponding first inclined push rod 3. Between the two opposite third inclined push rods 20, the same second V-shaped elastic piece 21 is fixedly connected. By pushing the first inclined push rod 3, the third inclined push rod 20 can produce a linkage effect.
[0031] As Figure 3 and Figure 7As shown, the edges of the limiting blocks 19 are all arc-shaped. When two opposite limiting blocks 19 are parallel to each other, the maximum distance between the two ends of these two limiting blocks 19 is greater than the diameter of the central conductor 16. When the outer joint 14 is inserted into the inside of the housing 1, the top end of the conductor 15 slides along the arc at the edge of the limiting block 19 and gradually expands. The limiting block 19 divides the conductor 15 into two parts and gradually slides into the inside of the housing 1. During this process, the conductor 15 will not touch the central conductor 16.
[0032] As Figure 4 and Figure 7 shown, chamfers are provided at the top ends of the third inclined push rods 20. The horizontal distance from the top ends of the third inclined push rods 20 to the third elastic piece 18 gradually increases in the direction of the outer surface of the central conductor 16. A slideway is provided at the bottom end of the sliding rod 17. The inner wall of the slideway fits with the top ends of the third inclined push rods 20. By pushing the third inclined push rods 20, the sliding groove can slide along the chamfer, so that the sliding rod 17 can gradually slide downward.
[0033] As Figure 3 and Figure 4 shown, sliding grooves are provided on both sides of the top end of the central conductor 16. The horizontal distance from the bottom ends of the sliding grooves to the third elastic piece 18 gradually increases in the direction of the center of the central conductor 16. The sliding grooves provide a sliding space for the limiting blocks 19. By pushing the sliding rod 17, the limiting blocks 19 are pulled into the inside of the central conductor 16. Since the bottom ends of the sliding grooves are inclined, the length of the inner wall bottom end of the sliding grooves is greater than that of the top end. Therefore, during the movement of the limiting blocks 19, they gradually fit with the inner wall bottom end of the sliding grooves, so that the limiting blocks 19 are received into the inside of the central conductor 16.
[0034] As Figure 4 and Figure 6 shown, an inclined angle is provided on the opposite side of the inclined push block 13 and the second inclined push rod 9. The horizontal distance from one side of the inclined push block 13 to the central conductor 16 gradually increases in the direction of the spring 2. A notch is provided at the top end of the second inclined push rod 9. The notch fits with the inclined angle. By pressing the second inclined push rod 9, the top end of the second inclined push rod 9 can squeeze the inclined angle of the inclined push block 13, so as to be able to push the inclined push block 13.
[0035] As Figure 5 and Figure 7 shown, inclined cutting surfaces are provided on one side of the third inclined push rod 20 and one side of the first inclined push rod 3. The two inclined cutting surfaces fit with each other. The horizontal distance from the inclined cutting surface of the third inclined push rod 20 to the central conductor 16 gradually decreases in the direction of the third elastic piece 18. By pressing the first inclined push rod 3, the inclined cutting surface of the first inclined push rod 3 can squeeze the inclined cutting surface of the third inclined push rod 20, so that the third inclined push rod 20 can slide along the inclined cutting surface.
[0036] Working principle: First, align the external connector 14 and insert it into the inside of the housing 1. When the conductor 15 contacts the limit block 19, the limit block 19 can push the two sides of the conductor 15 to separate, avoiding the contact and friction between the conductor 15 and the central conductor 16. Then, when the external connector 14 enters the bottom end of the inside of the housing 1, it will press the insulating sheet 8 and the ring sheet 4, causing the spring 2 and the first elastic sheet 7 to be squeezed and contracted, and pushing the first inclined push rod 3 to slide, so that the inclined plane of the first inclined push rod 3 can squeeze the inclined plane of the third inclined push rod 20, and then the third inclined push rod 20 can slide along the inclined plane, making the distance between the two opposite third inclined push rods 20 closer. At this time, the squeezing force of the third elastic sheet 18 on the sliding rod 17 becomes smaller, and the third elastic sheet 18 gradually returns to its original shape, thus pushing the sliding rod 17 to move, enabling the sliding groove to slide along the inclined angle, and the second V-shaped elastic sheet 21 is squeezed and contracted, so that the sliding rod 17 can gradually slide towards the direction of the third inclined push rod 20. Since the bottom end of the sliding groove in the central conductor 16 is inclined, the length of the inner wall bottom end of the sliding groove is greater than that of the top end, so that during the movement of the limit block 19 following the sliding rod 17, the limit block 19 gradually rotates and fits with the inner wall bottom end of the sliding groove, enabling the limit block 19 to be received into the inside of the central conductor 16. At the same time, during the sliding process of the first inclined push rod 3, the first inclined push rod 3 will push the second inclined push rod 9, so that the top end of the second inclined push rod 9 can squeeze the inclined angle of the inclined push block 13, thereby being able to push the inclined push block 13, and then push the extrusion strip 12. At this time, the first V-shaped elastic sheet 11 is squeezed and deformed, and the extrusion strip 12 thus squeezes the conductor 15, making the inner wall of the conductor 15 closely fit with the outer wall of the central conductor 16.
[0037] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
