DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] An embodiment of a coaxial connector with a mosaic pin of the present invention is as follows Figures 1 to 8 shown.

[0028] A coaxial connector with an embedded pin includes a male connector 100 and a female connector 200. The male connector 100 can move toward the female connector 200 along a first direction and plug into the female connector 200. The first direction is the plugging direction of the male connector 100 and the female connector 200. The female connector 200 includes a connection base 210 and a plurality of conductive members. The plurality of conductive members are evenly distributed on the connection base 210 around the first direction. The male connector 100 has a plurality of groups of plug wires 110 evenly distributed around the first direction. The plurality of groups of plug wires 110 are arranged one-to-one with the plurality of conductive members.

[0029] The conductive member includes a conductive shell 220, a plurality of winding rings 230 and a plurality of plug-in posts 240. The conductive shell 220 is arranged on the connection seat 210 along the first direction and is hollow inside. The conductive shell 220 is cylindrical. The plurality of winding rings 230 and the plurality of plug-in posts 240 are arranged on the conductive shell 220 in sequence along the first direction, and the winding rings 230 and the plug-in posts 240 are alternately distributed in sequence in the first direction. The plug-in posts 240 can move in the conductive shell 220 along the second direction, and the second direction is the radial direction of the conductive shell 220. The winding ring 230 can rotate around the first direction relative to the conductive shell 220, and each group of plug-in wires 110 can be plugged with the conductive shell 220 of the conductive member corresponding to it. And the rotation of the winding ring 230 can drive the plug-in wires 110 to rotate synchronously.

[0030] In this embodiment, when the male connector 100 and the female connector 200 are connected, the connection base 210 and the plurality of conductive members are provided to cooperate. When plugging, the plug wire 110 is first plugged into the conductive shell 220 of the conductive member corresponding to the plug wire 110. Then, starting from the plug post 240 close to the male connector 100 in the first direction, all the plug posts 240 arranged in the first direction are driven to be inserted into the conductive shell 220 in sequence, and after any plug post 240 is plugged into the conductive shell 220, all the winding rings 230 located on the side of the plug post 240 far from the male connector 100 in the first direction are rotated.

[0031] Take one of the conductive parts as an example for explanation. When in use, first extend a set of plug wires 110 into the corresponding conductive shell 220. The multiple plug posts 240 arranged in sequence along the first direction on the conductive shell 220 of the conductive part are respectively referred to as the first post, the second post, ... the Nth post. The first post is located on the side of the second post close to the male connector 100 in the first direction.

[0032] Then, the first column is inserted into the conductive shell 220, and the first column is used to separate the patch cords 110, so that each group of patch cords 110 is divided into two parts. Then, all the winding rings 230 located on the side of the first column away from the male connector 100 in the first direction are driven to rotate, and the rotation of the winding rings 230 will drive the patch cords 110 to rotate synchronously, so that the patch cords 110 divided into two parts are twisted and cross-wound on the first column. Then, the second column is driven to be plugged into the conductive shell 220, and the second column is used to separate the patch cord 110, so that each group of patch cords 110 is divided into two parts again, and then all the winding rings 230 located on the side of the second column away from the male connector 100 in the first direction are driven to rotate again. The rotation of the winding rings 230 will drive the patch cord 110 to rotate synchronously, so that the patch cord 110 divided into two parts will be twisted again and cross-wound on the second column. Then, the remaining third column, fourth column...Nth column are inserted into the conductive shell 220 in sequence, and after any plug-in column 240 is plugged into the conductive shell 220, all the winding rings 230 located on the side of the plug-in column 240 away from the male connector 100 in the first direction are rotated. Finally, each group of patch cords 110 is connected to the plug-in column 240 on the conductive shell 220 corresponding to it in a cross-wrap manner, see the attached Figure 6 It prevents excessive local stress on the patch cord 110, protects the structural integrity of the patch cord 110, and prevents the patch cord 110 from being deformed or broken. The patch cord 110 is connected in a cross-wrap manner by the cooperation of the plug post 240 and the winding ring 230, and the connection is not easy to loosen, and is more stable and reliable.

[0033] In this embodiment, a plurality of mounting slots 211 are formed on the connection base 210 . The plurality of mounting slots 211 are arranged in one-to-one correspondence with the plurality of conductive shells 220 . Each conductive shell 220 is installed in the corresponding mounting slot 211 .

[0034] Specifically, four groups of patch cords 110 are provided, and four conductive shells 220 and four mounting slots 211 are provided.

[0035] Furthermore, a connecting sleeve 212 is provided on the connecting seat 210, an internal thread 213 is provided on the connecting sleeve 212, and an external thread 101 is provided on the male head 100. The internal thread 213 and the external thread 101 are rotatably matched, so that the male head 100 can be locked with the female head 200 through the connecting sleeve 212.

[0036] The connecting sleeve 212 includes a fixed portion 214 and a rotating portion 215. The fixed portion 214 is sleeved on the connecting seat 210 and fixedly connected to the connecting seat 210. The rotating portion 215 is rotatably matched with the fixed portion 214. That is, an annular groove is provided on the fixed portion 214, and an annular protrusion is provided on the rotating portion 215. The annular protrusion is rotatably matched with the annular groove. The internal thread 213 is provided on the rotating portion 215.

[0037] In this embodiment, the plug-in column 240 is threadedly matched with the connection base 210, and a plug hole is provided on the plug-in column 240. One end of the plug-in column 240 inserted into the conductive shell 220 in the second direction is tapered.

[0038] The conductive shell 220 is provided with moving grooves 221 , and the moving grooves 221 are arranged in one-to-one correspondence with the plug-in posts 240 . Each plug-in post 240 can move along the second direction in the corresponding moving groove 221 .

[0039] When in use, the operator can insert a wrench into the insertion hole and rotate the plug post 240, so that the plug post 240 rotates around its own axis and moves in the second direction to be inserted into the conductive shell 220. Since the end of the plug post 240 inserted into the conductive shell 220 in the second direction is tapered, after the plug post 240 is inserted into the conductive shell 220, the plug wire 110 can be easily separated into two parts under the action of the plug post 240.

[0040] In another possible embodiment, the plug-in column 240 includes a body 241, a rotating ring 242 and an adjusting ring 243. The end of the body 241 inserted into the conductive shell 220 in the second direction is conical. The jack is provided on the body 241. The rotating ring 242 and the adjusting ring 243 are both sleeved with the body 241 and are sequentially arranged on the body 241 along the second direction, and the rotating ring 242 is located on the side of the adjusting ring 243 in the second direction close to the central axis of the conductive shell 220 in the first direction. The rotating ring 242 is threadedly matched with the connecting seat 210. The rotating ring 242 is matched with the keyway of the body 241, so that the rotating ring 242 can rotate with the body 241 and can move relative to the body 241 in the second direction. The adjusting ring 243 is fixedly connected to the body 241 at one end along the second direction, and fixedly connected to the rotating ring 242 at the other end in the second direction.

[0041] Furthermore, the body 241 is hollow inside. By setting the body 241 as a hollow structure, heat dissipation is facilitated.

[0042] Furthermore, the adjustment ring 243 is made of alloy material and has a large thermal expansion coefficient, which is greater than the thermal expansion coefficients of the main body 241 and the rotating ring 242. The adjustment ring 243 can expand when heated and contract when cooled.

[0043] When in use, the main body 241 is rotated, and the rotation of the main body 241 will drive the rotating ring 242 to rotate synchronously. Since the rotating ring 242 is threadedly matched with the connecting seat 210, the main body 241 will rotate together with the rotating ring 242 while moving in the second direction, and drive the adjusting ring 243 to move synchronously, that is, at this time, the main body 241, the rotating ring 242 and the adjusting ring 243 all rotate and move in the second direction.

[0044] When heat is generated during use, the plug wire 110 will swell due to the heat, squeezing the plug post 240, causing the stress between the plug post 240 and the plug wire 110 to increase. At this time, the adjusting ring 243 can be heated and expanded synchronously, that is, the size of the adjusting ring 243 in the second direction will become larger, thereby causing the main body 241 and the rotating ring 242 to tend to move away from each other in the second direction. However, since the rotating ring 242 is threadedly matched with the connecting seat 210, the movement of the rotating ring 242 in the second direction is limited, so that when the adjusting ring 243 is heated and expanded, the adjusting ring 243 will cause the main body 241 to move in the second direction to the side away from the central axis of the conductive shell 220 in the first direction. Because the end of the main body 241 inserted into the conductive shell 220 is tapered, the movement of the main body 241 will relatively increase the gap between the main body 241 and the plug wire 110, thereby reducing the stress between the plug post 240 and the plug wire 110.

[0045] When the temperature is low during use, the plug wire 110 will shrink due to the cold, so that the gap between the plug post 240 and the plug wire 110 is relatively reduced, and at this time the adjustment ring 243 will shrink when it is cold, that is, the size of the adjustment ring 243 in the second direction will become smaller, so that the main body 241 and the rotating ring 242 tend to approach each other in the second direction, but because the rotating ring 242 is threadedly matched with the connecting seat 210, the movement of the rotating ring 242 in the second direction is limited, so that when the adjustment ring 243 shrinks when it is cold, the adjustment ring 243 will cause the main body 241 to move in the second direction toward the side of the central axis of the conductive shell 220 in the first direction, and because the end of the main body 241 inserted into the conductive shell 220 is tapered, the movement of the main body 241 will cause the gap between the main body 241 and the plug wire 110 to be relatively reduced, thereby ensuring the stability of the connection between the plug wire 110 and the plug post 240.

[0046] In this embodiment, a plurality of winding rings 230 on the connecting seat 210 in the same circumferential direction are referred to as a winding group. An active ring 250 is sleeved on each winding group. The active ring 250 is coaxial with the connecting seat 210 and can rotate around its own axis. The active ring 250 is meshed with the winding rings 230 of the winding group, and the rotation of the active ring 250 can drive the winding rings 230 of the winding group meshed with it to rotate.

[0047] Specifically, the inner wall surface of the active ring 250 and the outer wall surface of the winding ring 230 are both friction surfaces. The active ring 250 is frictionally transmitted with the winding ring 230 engaged with it, so that the rotation of the active ring 250 can drive the winding ring 230 of the winding group engaged with it to rotate.

[0048] Furthermore, a plurality of one-way teeth 216 are provided on the connecting seat 210, and the one-way teeth 216 are elastic. The plurality of one-way teeth 216 are provided one-to-one correspondingly with the plurality of active rings 250, and a ratchet ring 251 is provided on the inner circumferential wall surface of each active ring 250, and the ratchet ring 251 is meshed with the one-way teeth 216 provided correspondingly thereto.

[0049] When in use, the operator can manually rotate the active ring 250, and drive the multiple winding rings 230 on the same winding group to rotate through the active ring 250. In addition, a ratchet ring 251 is provided on the active ring 250 to prevent the active ring 250 from rotating and improve the stability of the connection.

[0050] In this embodiment, the winding ring 230 includes a ring plate 231, a support ring 232 and a synchronization ring 233. The ring plate 231 is semi-circular, the support ring 232 is circular, the support ring 232 and the ring plate 231 are coaxially arranged and fixedly connected, the synchronization ring 233 is elliptical, and the synchronization ring 233 is located on the inner side of the support ring 232 and is fixedly connected to the support ring 232. A rotation cavity 217 is provided on the connecting seat 210, and a rotation groove 222 is provided on the conductive shell 220. The rotation cavity 217, the rotation groove 222 and the ring plate 231 are arranged one by one, and the rotation cavity 217 is connected to the corresponding rotation groove 222. The ring plate 231 passes through the corresponding rotation groove 222 and the rotation cavity 217, and can rotate in the corresponding rotation cavity 217 and the rotation groove 222. The support ring 232 and the synchronization ring 233 are both located in the conductive shell 220.

[0051] By providing the ring plate 231, the support ring 232 and the synchronization ring 233. When the plug wire 110 is plugged into the conductive shell 220 of the conductive member corresponding thereto, the plug wire 110 will pass through the synchronization ring 233 and be limited by the synchronization ring 233. When the ring plate 231 rotates, the ring plate 231 will drive the synchronization ring 233 to rotate through the support ring 232, and the rotation of the synchronization ring 233 will drive the plug wire 110 therein to rotate synchronously, thereby causing the plug wire 110 to twist, and the plug post 240 is cross-wound by the plug wire 110 divided into two parts.

[0052] In combination with the above embodiments, the specific working process is as follows:

[0053] During the plugging process, the operator moves the male connector 100 by hand, and first plugs the plug wire 110 into the conductive shell 220 of the conductive member corresponding thereto. At this time, the plug post 240 does not extend into the conductive shell 220 .

[0054] Taking one of the conductive members as an example, the plurality of plugging posts 240 sequentially arranged along the first direction on the conductive shell 220 of the conductive member are respectively referred to as the first post, the second post, ... the Nth post. The first post is located on the side of the second post close to the male connector 100 in the first direction.

[0055] During plugging, the operator holds a wrench, inserts the wrench into the jack, and rotates the first column to insert the first column into the conductive shell 220, and uses the first column to separate the patch cords 110, thereby dividing each group of patch cords 110 into two parts.

[0056] Then manually rotate all the active rings 250 located on the side of the first column away from the male head 100 in the first direction, and drive the multiple winding rings 230 on the same winding group to rotate through the active rings 250. The rotation of the winding rings 230 will drive the patch cord 110 to rotate synchronously, so that the patch cord 110 divided into two parts will be twisted and cross-wound on the first column.

[0057] Then, the second column is driven to be plugged into the conductive shell 220, and the second column is used to separate the patch cord 110, so that each group of patch cords 110 is divided into two parts again, and then all the active rings 250 located on the side of the second column away from the male plug 100 in the first direction are driven to rotate again, and the active rings 250 are used to drive the multiple winding rings 230 on the same winding group to rotate. The rotation of the winding rings 230 will drive the patch cord 110 to rotate synchronously, so that the patch cord 110 divided into two parts will be twisted and cross-wound on the second column.

[0058] Then, the remaining third column, fourth column, ... Nth column are sequentially inserted into the conductive shell 220, and after any plug-in column 240 is plugged into the conductive shell 220, all the active rings 250 located on the side of the plug-in column 240 away from the male connector 100 in the first direction are rotated. Finally, each group of plug wires 110 is connected to the plug-in column 240 on the conductive shell 220 corresponding to it in a cross-wrap manner, see the attached Figure 6 The connector is installed once and does not need to be disconnected after use.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
