[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution 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, such as Figure 1 to Figure 2As shown, it includes a shell 1, four springs 2 are installed inside the shell 1, and No. 1 oblique push rods 3 are fixedly installed on the top of the four springs 2, and the same ring piece 4 is fixedly connected between two No. 1 oblique push rods 3 relative to each other, two outer conductors 5 are fixedly installed inside the shell 1, and two insulators 6 are fixedly installed inside the two outer conductors 5, and No. 1 spring pieces 7 are fixedly installed on both sides of the top of the two insulators 6, and the tops of the two insulators 6 are located at the top of the No. 1 oblique push rods 3. The same insulating piece 8 is fixedly connected to the tops of the two No. 1 spring pieces 7 relative to each other, and No. 2 oblique push rods 9 are slidably installed on both sides of the two outer conductors 5 at the bottom of the No. 1 oblique push rods 3, and No. 2 spring pieces 10 are fixedly installed on the bottom ends of the four No. 2 oblique push rods 9, and two No. 1 V-shaped spring pieces 11 are fixedly installed on both sides of the two outer conductors 5, and the same extrusion strip 12 is movably sleeved between the two No. 1 V-shaped spring pieces 11, and one side of the four extrusion strips 12 is located at the top of the No. 2 oblique push rods 9 and is fixedly installed with oblique push blocks 13.

[0027] like Figure 1 and Figure 2 As shown, an external connector 14 is snap-fitted inside the housing 1 , and two conductors 15 are arranged inside the external connector 14 . By inserting the external connector 14 into the housing 1 , the housing 1 is fixed to the external connector 14 , thereby ensuring the stability of the connection of the external connector 14 .

[0028] Example 2

[0029] The present invention also provides a high-frequency and high-speed connector, such as Figures 3 to 7 As shown, the plug housing 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. Sliding rods 17 are slidably installed inside the two center conductors 16. No. 3 spring pieces 18 are fixedly installed at the top positions of the sliding rods 17 inside the two center conductors 16. Limiting blocks 19 are rotatably installed on both sides of the top ends of the two sliding rods 17.

[0030] like Figure 4 and Figure 7 As shown, No. 3 inclined push rods 20 are slidably installed at both ends of the two center conductors 16 at the bottom end of the sliding rod 17, and one side of the four No. 3 inclined push rods 20 is fitted with one side of the corresponding No. 1 inclined push rod 3, and the same No. 2 V-shaped spring piece 21 is fixedly connected between the two No. 3 inclined push rods 20, and by pushing the No. 1 inclined push rod 3, the No. 3 inclined push rods 20 can produce a linkage effect.

[0031] like Figure 3 and Figure 7As shown, the edges of the limit blocks 19 are all set to be arc-shaped. When the two relative limit blocks 19 are parallel to each other, the farthest distance between the two ends of the two limit blocks 19 is greater than the diameter of the center conductor 16, so that when the external connector 14 is inserted into the shell 1, the top end of the conductor 15 slides along the arc of the edge of the limit block 19 and gradually expands. The limit block 19 divides the conductor 15 into two lobes and gradually slides into the shell 1. In this process, the conductor 15 will not touch the center conductor 16.

[0032] like Figure 4 and Figure 7 As shown, the top of the No. 3 inclined push rod 20 is provided with an oblique angle, and the horizontal distance between the top of the No. 3 inclined push rod 20 and the No. 3 spring 18 gradually increases toward the outer surface of the center conductor 16. The bottom of the sliding rod 17 is provided with a slideway, and the inner wall of the slideway fits with the top of the No. 3 inclined push rod 20. By pushing the No. 3 inclined push rod 20, the slide groove can slide along the oblique angle, so that the sliding rod 17 can gradually slide to the bottom.

[0033] like Figure 3 and Figure 4 As shown, slide grooves are provided on both sides of the top of the center conductor 16, and the horizontal distance between the bottom end of the slide groove and the No. 3 spring 18 gradually increases toward the center direction of the center conductor 16. The slide groove provides a sliding space for the limit block 19, and the limit block 19 is pulled into the center conductor 16 by pushing the sliding rod 17. Since the bottom end of the slide groove is inclined, the bottom end of the inner wall of the slide groove is longer than the top end, so that the limit block 19 gradually fits with the bottom end of the inner wall of the slide groove during the movement, so that the limit block 19 is retracted into the center conductor 16.

[0034] like Figure 4 and Figure 6 As shown, the inclined push block 13 and the second inclined push rod 9 have an inclination angle on one side opposite to each other, and the horizontal distance between one side of the inclined push block 13 and the center conductor 16 gradually increases in the direction of the spring 2. The top end of the second inclined push rod 9 has a notch, and the notch and the inclination angle fit each other. By pressing the second inclined push rod 9, the top end of the second inclined push rod 9 can squeeze the inclination angle of the inclined push block 13, thereby pushing the inclined push block 13.

[0035] like Figure 5 and Figure 7 As shown, one side of the No. 3 inclined push rod 20 and one side of the No. 1 inclined push rod 3 are both provided with beveled surfaces, and the two beveled surfaces fit each other, wherein the horizontal distance between the beveled surface of the No. 3 inclined push rod 20 and the center conductor 16 gradually decreases toward the direction of the No. 3 spring piece 18, and by pressing the No. 1 inclined push rod 3, the beveled surface of the No. 1 inclined push rod 3 can squeeze the beveled surface of the No. 3 inclined push rod 20, thereby allowing the No. 3 inclined push rod 20 to slide along the beveled surface.

[0036] Working principle: first, align the external connector 14 with the interior of the shell 1 and insert it. When the conductor 15 contacts the limit block 19, the limit block 19 can push the two sides of the conductor 15 apart to avoid contact and friction between the conductor 15 and the center conductor 16. Then, when the external connector 14 enters the bottom end of the shell 1, it will press the insulating sheet 8 and the ring sheet 4, so that the spring 2 and the No. 1 spring piece 7 are squeezed and contracted, and push the No. 1 inclined push rod 3 to slide, so that the beveled surface of the No. 1 inclined push rod 3 can squeeze the beveled surface of the No. 3 inclined push rod 20, and then the No. 3 inclined push rod 20 can slide along the beveled surface, so that the distance between the two No. 3 inclined push rods 20 is close. At this time, the squeezing force of the sliding rod 17 on the No. 3 spring piece 18 becomes smaller, and the No. 3 spring piece 18 gradually returns to its original shape, thereby pushing the sliding rod 17 to move, so that the slide groove can slide along the bevel, and the No. 2 V-shaped spring The sheet 21 is squeezed and contracted, so that the sliding rod 17 can gradually slide toward the direction of the third inclined push rod 20. Since the bottom end of the inner groove of the center conductor 16 is inclined, the bottom end of the inner wall of the groove is longer than the top end, so that the limit block 19 gradually rotates and fits with the bottom end of the inner wall of the groove during the movement of the sliding rod 17, so that the limit block 19 is retracted into the center conductor 16. At the same time, during the sliding of the No. 1 inclined push rod 3, the No. 1 inclined push rod 3 will push the No. 2 inclined push rod 9, so that the top end of the No. 2 inclined push rod 9 can squeeze the inclination angle of the inclined push block 13, thereby pushing the inclined push block 13, and then pushing the extrusion bar 12. At this time, the No. 1 V-shaped spring piece 11 is squeezed and deformed, and the extrusion bar 12 squeezes the conductor 15, so that the inner wall of the conductor 15 is tightly fitted with the outer wall of the center conductor 16.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
