[0033] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation method, structure, characteristics and effects of the curved radio frequency hair button connector proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0034] See also Figure 1-10 , which is a schematic diagram of the structure of each part of the curved radio frequency button connector of the present invention, the connector includes a shell composed of a first shell 11 and a second shell 7, a curved contact is positioned and assembled in the shell, the curved contact includes a pin 4 extending along a first direction and a second button 10 extending along a second direction, and the tail of the second button 10 is pressed on the outer peripheral surface of the front end of the pin 4 to achieve elastic contact with the pin 4, meeting the needs of signal transmission. There is an angle between the first direction and the second direction.

[0035] The portion of the front end of the pin 4 for elastically contacting the second fur button 10 is defined as the contact section 41, and the cross section of the portion of the pin 4 other than the contact section 41 is a circular surface, which is defined as the positioning section. In this embodiment, the outer periphery of the contact section 41 of the pin 4 and the surface of the elastic contact piece of the second fur button 10 are planes, which are defined as contact planes 411. The contact planes 411 are parallel to the first direction, and the first direction and the second direction are perpendicular to each other, so that the second fur button 10 and the contact plane 411 are vertically elastically interconnected, realizing the vertical turn of the signal. Preferably, the cross section of the front end contact section 41 of the pin 4 is a rectangular surface, the contact section 41 is flat as a whole, and the front end face is arc-shaped. In other embodiments of the present invention, the direction of the contact plane 411 can be set as needed, and then on the premise of ensuring that the second direction is perpendicular to the contact plane 411 (making the second fur button 10 and the contact plane 411 vertically elastically contact, ensuring stable and reliable contact), curved contact pieces with different bending directions can be formed to meet different usage requirements.

[0036] In the embodiment of the present invention, the plug pin 4 is fixedly assembled in the plug pin positioning hole 111 in the first housing 11 through an insulator. There are multiple plug pin positioning holes 111, and each plug pin positioning hole 111 has a corresponding plug pin 4 fixed therein. Multiple insulators are distributed in each plug pin positioning hole 111 along its axial direction, respectively realizing the support and fixation of different axial positions of the plug pin 4. Specifically, the first insulator 1, the second insulator 2, the third insulator 3 and the fourth insulator 12 are fixed in the plug pin positioning hole 111 in sequence from front to back along the axial direction, wherein the first insulator 1 is used to realize the fixed positioning of the contact segment 41 of the front end of the plug pin 4 and the elastic contact of the second wool button 10. Since the cross section of the contact segment 41 is rectangular, the hole in the first insulator 1 for realizing the positioning of the contact segment 41 is rectangular. In order to facilitate the contact and conduction between the contact plane 411 on one side of the contact segment 41 at the front end of the plug pin 4 and the second wool button 10, the first insulator 1 is open on the side corresponding to the contact plane 411 to form a U-shaped hole adapted to the contact segment 41. Preferably, the first insulator 1 is U-shaped as a whole, and the portion of the pin positioning hole 111 that is adapted to the first insulator is also U-shaped with one side open. The U-shaped structural design of the first insulator 1 can not only meet the fixed positioning of the contact segment 41 of the pin 4, but also achieve circumferential rotation prevention of the pin 4, and further achieve orientation of the contact plane 411.

[0037] The pin 4 positioning section also includes a small diameter section 42 with a smaller outer diameter, and the second insulator 2 is fixedly sleeved on the outer periphery of the small diameter section 42. The axial dimension of the second insulator 2 is consistent with the small diameter section 42, and the outer diameter is larger than the maximum outer diameter of the pin 4 positioning section. A limiting step 112 for blocking the front end surface of the second insulator 2 is provided in the pin positioning hole 111, and the limiting step 112 cooperates with the second insulator 2 to realize the axial forward limiting of the pin 4.

[0038] The portion of the positioning section of the plug pin 4 located behind the small diameter section 42 passes through the third insulator 3 and the fourth insulator 12 in sequence, and is fixed and supported in the plug pin positioning hole 111 by the third insulator 3 and the fourth insulator 12. Preferably, the third insulator 3 and the fourth insulator 12 have completely identical shapes, both of which have large outer diameters at both ends and small outer diameters in the middle. In other embodiments of the present invention, the insulator for fixing and positioning the plug pin 4 may also be other structural forms, as long as it can meet the reliable positioning of the plug pin 4 in the plug pin positioning hole 111.

[0039] In the embodiment of the present invention, both contact ends of the bent contact piece are elastic solder-free contact structures. Specifically, the end face of the tail of the plug pin 4 is also elastically in contact with the first wool button 5 extending along the first direction, the first wool button 5 is located in the fifth insulator 13, and the part of the tail of the plug pin 4 that passes through the fourth insulator 12 enters the fifth insulator 13 and elastically contacts the front end of the first wool button 5. The cooperation between the tail of the plug pin 4 and the fifth insulator 13 of the present invention helps to ensure the consistency of the plug pin 4 and the first wool button 5 in the axial direction, and realizes the coaxial positioning of the contact piece in the pin positioning hole 111.

[0040] The fifth insulator 13 is axially positioned in the pin positioning hole 111 by the cooperation between its peripheral barb structure 131 and the groove in the pin positioning hole 111. After being assembled in place, the fifth insulator 13 also axially presses the fourth insulator 12, so that the fourth insulator 12 presses the third insulator 3 against the second insulator 2, thereby realizing the axial rearward positioning of the pin 4 in the pin positioning hole 111.

[0041] In the embodiment of the present invention, the fur buttons at both ends of the bent contact piece realize elastic solder-free contact with the adapter end through the floating head extending out of the shell. Specifically, the fifth insulator 13 is also provided with a first floating head 6, one end of which is located in the fifth insulator 13, and the other end extends out of the fifth insulator 13, and the fifth insulator 13 is also provided with a limiting structure to prevent the first floating head 6 from escaping from the fifth insulator 13. In the unused state, one end of the first fur button 5 is pressed tightly on the tail end face of the pin 4, and the other end provides the first floating head 6 with elastic force to escape from the tail of the fifth insulator 13, so that the stepped surface of the outer periphery of the first floating head 6 is pressed on the limiting structure in the fifth insulator 13, and the state of partially extending out of the fifth insulator is maintained. When in contact with a printed circuit board or other connector, the first floating head 6 is pressed tightly on the structure of the adapter contact, and axially retreats to disengage from the limiting structure in the fifth insulator. At this time, the first fur button 5 provides a reliable end face contact force for the first floating head 6.

[0042] The second fur button 10 is fixedly assembled in the fur button positioning hole 71 in the second shell 7 through the sixth insulator 8. The second shell 7 has a plurality of fur button positioning holes 71 extending in a direction perpendicular to the pin positioning hole 111, and the pin positioning holes 111 correspond to the fur button positioning holes 71 one by one and are vertically interconnected. The sixth insulator 8 is fixed in the fur button positioning hole 71. Preferably, the sixth insulator 8 is fixedly positioned in the fur button positioning hole 71 by the cooperation of its peripheral barbs with the positioning grooves in the fur button positioning hole 71. The second fur button 10 is located in the mounting hole of the sixth insulator 8, and the front end of the second fur button 10 is in elastic contact with the tail end face of the second floating head 9. The tail end of the second floating head 9 is located in the mounting hole, and the front end extends out of the mounting hole. A limiting step is also provided in the mounting hole to prevent the second floating head 9 from falling out of the mounting hole under the elastic force of the second fur button 10. The provision of the second floating head 9 of the present invention realizes the elastic surface connection between the second wool button 10 and the external device, and also makes the second wool button 10 always in an elastic compression state, so as to maintain stable elastic contact with the contact plane around the pin 4.

[0043] In the embodiment of the present invention, a boss 114 is provided on one side of the front end face of the first shell 11, and a radial portion of the pin positioning hole 111 is located inside the boss 114, so that the pin positioning hole 111 is a rectangular groove with one side open at the boss 114. Preferably, a guide structure is formed at the notch of the rectangular groove to facilitate the installation of the first insulator 1. The second shell 7 is fixed on the front end face of the first shell 11 and is engaged with the boss 114, so that the button positioning hole 71 in the second shell 7 is opposite to the open side of the pin positioning hole 111 on the boss 114, and the second shell 7 cooperates with the first shell 11 with the boss 114 to form a completely closed curved positioning hole.

[0044] In this embodiment, the first shell 11 and the second shell 7 are fixed together by a rivet 15 and a hollow piercing column 14. The rivet 15 is arranged parallel to the button positioning hole 71, and multiple rivets are arranged in the distribution direction of the button positioning hole 71. In this embodiment, three protrusions 72 are arranged at intervals at the bottom of the second shell 7, and a side of the upper end surface of the first shell 11 away from the boss 114 is provided with an escape groove 113 for the above-mentioned protrusion 72 to enter. The escape groove 113 is a U-shaped groove with one side open. The rivet 15 enters from the open part of the side of the escape groove 113 and fixes the protrusion 72 to the first shell 11. The rivet part of the rivet 15 is located on the surface of the first shell 11 away from the second shell 7. The two ends of the second shell 7 of the present invention are also fixed to the boss 114 on the first shell 11 by the rivet 15.

[0045] The upper end of the second shell 7 also extends to one side to form a lap portion 73 for pressing on the boss 114. The lap width of the lap portion 73 on the boss 114 is greater than the width of the pin positioning hole 111 on the boss 114, so that the lap portion 73 can completely cover the portion of the boss 114 where the pin positioning hole 111 is located. In this embodiment, in order to facilitate the assembly of the pin 4, the pin positioning hole 111 is a through hole so that the pin 4 can be assembled from top to bottom. The lap portion 73 can cover and protect the pin positioning hole. In this embodiment, a groove 1121 is formed on one side of the boss 114 where the pin positioning hole 111 is provided. The lap portion 73 is located in the groove 1121 and partially extends out of the groove 1121. The lap portion 73 and the bottom of the groove 1121 are fixed by a hollow puncture column 14. Preferably, there are three hollow puncture columns 14, including a hollow columnar structure 142 at the front end and a solid columnar structure 141 at the rear end, and the outer periphery of the hollow columnar structure 142 is provided with a spur 143, and the outer periphery of the front end of the solid columnar structure is provided with a guide structure 144. The hollow puncture column 14 is forcibly installed in the hole on the overlap portion 73 by tool interference fit, at which time the rear end of the solid columnar structure is located in the hole on the boss 114 and matches with a small gap with the hole on the boss 114. The hollow design on the hollow puncture column 14 of the present invention can cause the hollow puncture column to partially deform inward when forcibly installed, and can prevent the spur 143 from breaking or bulging the thin-walled structure of the second shell.

[0046] The curved contact piece of the present invention may be composed of only a pin and a second fur button, or may be composed of a socket and a second fur button. In this case, one end of the curved contact piece is a pin or a socket structure, and the other end is a fur button structure. The curved contact piece of the present invention may also be a structure composed of only a pin, a first fur button and a second fur button. In this case, both ends of the curved contact piece are elastic contact structures. When the present invention cancels the design of the floating head, and the fur button directly extends out of the shell and elastically contacts with the adapter end, a convex rib is provided in the middle of the insulator used to fix the fur button, so that the two ends of the insulator are gap-fitted with the fur button, and the middle part is interference-fitted with the fur button, so as to realize reliable positioning of the fur button in the insulator.

[0047] The connector of the present invention is used to adapt to a printed circuit board to realize vertical interconnection of the printed circuit boards. Positioning posts 16 for realizing positioning on the printed circuit board are provided on both butt end faces of the connector.
