Description

Technical Field

[0001] The invention relates to the field of connectors, and in particular to a coaxial connector for cable connection and a detection method thereof. Background Art

[0002] A coaxial connector is a part used to connect the ends of two cables to ensure that the ends of the two cables are butted and conductive.

[0003] The coaxial connector has a male head and a female head that are combined together to form a pair. In the prior art, the male head and the female head are plugged together, and both the male head and the female head have threads, and the two are further fixed by the threads. The threaded connection method is tightened by tools, which is inconvenient. In addition, if the threaded parts of the male head and the female head are rusted during use, the male head and the female head will be difficult to separate due to the rust, affecting the disassembly of the two heads, which needs to be improved. Summary of the invention

[0004] In order to facilitate the disassembly and assembly of a coaxial connector, the present invention provides a coaxial connector for cable connection and a detection method thereof.

[0005] In a first aspect, the present invention provides a coaxial connector for cable connection, which adopts the following technical solution: A coaxial connector for cable connection, comprising a female head and a male head plugged with the female head, characterized in that the male head has a snap-in end; the female head comprises a female head housing, a cable sleeve slidably mounted in the inner cavity of the female head housing for cable installation, a sliding sleeve sleeved and slidably mounted on the outer side of the female head housing, and a reset component for driving the sliding sleeve to reset; An accommodating cavity is formed between the end of the cable sleeve close to the male connector and the female connector housing, a side opening penetrating to the accommodating cavity is formed on the side wall of the female connector housing, and a side cover is provided on the female connector housing to cover the side opening; The sliding sleeve has a locked state and an unlocked state; in the unlocked state, the sliding sleeve slides in a direction away from the male head to allow the side cover to open and the snap-in end to be snapped in; in the locked state, the sliding sleeve is pressed against the side wall of the side cover and locks the snap-in end in the accommodating cavity.

[0006] By adopting the above technical solution, when the male head and the female head are matched, the side opening on the female head shell can be opened by moving the sliding sleeve, and the male head is directly inserted into the accommodating cavity from the side wall of the female head. When the male head is in the accommodating cavity, the side opening is covered by the side cover, and finally the sliding sleeve is reset. When the cable is connected by the above structure, the male head and the female head are not easy to be disengaged because the side wall is blocked by the side opening and the sliding cover, and the above male head and the female head match in a way that the disassembly and assembly are relatively easy without complicated steps.

[0007] Optionally, the sliding sleeve and the cable sleeve are connected by a connecting structure so that the sliding sleeve drives the cable sleeve to slide, and the connecting structure includes a connecting block circumferentially arranged on the outside of the cable sleeve; an entry groove for the connecting block to slide is opened on the inner wall of the sliding sleeve along the length direction, and a fixing groove for the connecting block to be inserted is opened vertically at the tail of the entry groove; a sliding groove for the connecting block to slide is opened on the female shell along the length direction; the sliding groove and the entry groove are staggered so that the female shell can lock the connecting block in the fixing groove.

[0008] By adopting the above technical solution, by connecting the sliding sleeve with the cable sleeve, when the sliding sleeve switches from the locked state to the unlocked state, the cable sleeve can also move in the female head housing, so that when the male head and the female head are matched, the accommodating cavity has a large space for the male head to be inserted and installed. In addition, when the sliding sleeve slides, the cable sleeve of the female head can also be pressed against the male head, so that the two are tightly connected.

[0009] Optionally, the reset assembly includes a fixed seat connected to the end of the female housing, a rotating ring rotatably mounted on the fixed seat, and a reset spring; a telescopic chamber for the sliding groove to be inserted and telescoped is formed between the rotating ring and the female housing; the reset spring is arranged in the telescopic chamber and one end of which is connected to the end of the sliding sleeve; The fixing seat is circumferentially provided with a limiting adjustment block that is inserted into the sliding groove to limit the connecting block to the sliding groove; the limiting adjustment block is provided with adjustment teeth, and the sliding groove has shift grooves spaced apart along the length direction for the adjustment teeth to selectively insert to adjust the elastic force of the return spring.

[0010] By adopting the above technical solution, by pressing the fixing seat, the adjustment block can be limited to slide in the sliding groove so that the adjustment tooth switches position in the gear groove, and the elastic force of the reset spring can be adjusted when the adjustment tooth switches position. When the sliding sleeve of the coaxial connector is pressed for a long time and the elasticity of the reset spring is reduced, the reset spring can be pre-tightened again through the above result, so that the reset spring always exerts a large pressure on the sliding sleeve to lock the side port and the side cover, and it is not easy to open when the coaxial connector is used.

[0011] Optionally, the outer circumference of the sliding sleeve is provided with a locking block; the inner wall of the rotating ring is provided with a locking groove for arranging the locking block so that the sliding sleeve is in a locked state, an unlocking groove for arranging the locking block so that the sliding sleeve is in an unlocked state, and a connecting channel connecting the locking groove and the unlocking groove for sliding of the locking block; The connecting channel includes an unlocking path for the sliding sleeve to switch from a locked state to an unlocked state and is obliquely opened, and a locking path for the sliding sleeve to return from an unlocked state to a locked state and is axially opened along the rotating ring; the locking path connects the unlocking groove and the adjacent locking groove; The top of the fixing seat is provided with a snap-in strip; the bottom of the rotating ring is provided with an unlocking slot for the snap-in strip to be inserted into and for the locking block to be locked in the unlocking slot, and a sliding slot for the locking block to slide in the connecting channel.

[0012] By adopting the above technical solution, by driving the rotating ring to rotate, the sliding sleeve can switch back and forth between the locked state and the unlocked state, and the fixed seat and the rotating ring can rotate relatively. When the card strip is inserted into the unlocking slot, the sliding sleeve can be locked in the unlocked state, which facilitates the disassembly and assembly of the coaxial connector.

[0013] When the sliding sleeve is directly driven to slide, the fixed seat and the rotating ring will not rotate relative to each other. At this time, when the sliding sleeve is pushed to the unlocked state, it will not be locked in the unlocked state, so that the sliding sleeve can automatically reset when it is loosened. This method can be used to check the connection status of the coaxial connector, and it will automatically lock after the check is completed, which is more convenient.

[0014] Optionally, the snap-in end has a limiting ring in the circumference, and the accommodating cavity has a sealing ring that limits the snap-in end from escaping axially; a clamping assembly that drives the male head to be axially pressed against the female head is arranged in the accommodating cavity; the clamping assembly includes a clamping ring and a clamping spring circumferentially connected to the clamping ring, and the other end of the clamping spring is connected to the sealing ring; The inner wall of the accommodating cavity is provided with a limiting groove and a contact piece is rotatably arranged in the limiting groove, and the contact piece is driven by a compression spring to extend out of the limiting groove and contact the clamping ring; When the snap-in end is in the accommodating cavity, the snap-in end drives the abutting piece to be pressed into the limiting groove, and the limiting ring abuts against the clamping ring.

[0015] By adopting the above technical solution, when the snap-in end of the male head is installed into the accommodating cavity, the clamping spring can drive the clamping ring to abut against the snap-in end, so that the male head can be further approached to the female head under the elastic force of the clamping spring, making the connection between the two tighter, the conductive effect better, and less prone to poor contact.

[0016] Optionally, the side cover is rotatably mounted on the female housing, and the female housing is provided with a fixing assembly for fixing the side cover; the side cover is provided with an insertion block, and the female housing is provided with an insertion slot for inserting the insertion block; the female housing is provided with a mounting channel communicating with the insertion slot; The fixing assembly includes a fixing rod slidably installed on the installation channel and a driving spring driving the fixing rod to slide; the fixing rod is provided with a fixing block, and the fixing block is directly opposite to the insertion slot, and a guiding inclined surface is provided on one side of the fixing block facing the insertion slot; the insertion block has an arrangement groove for the fixing block to be inserted into.

[0017] By adopting the above technical scheme, the structural form of the fixing assembly is specifically disclosed. When the side cover covers the side opening, the insertion block is inserted into the insertion groove. The fixing rod is moved under the drive of the insertion block and can make the fixing block snap into the arrangement groove of the insertion block, thereby locking the insertion block in the insertion groove. At this time, the side cover is not easy to be loosened or tightened from the side opening, and the side cover can press the male head into the accommodating cavity of the female head.

[0018] Optionally, a through shrinkage groove is circumferentially provided at the snap-in end, and a flared portion is provided at one side of the cable sleeve close to the snap-in end.

[0019] By adopting the above technical solution, when the snap-in end is inserted into the accommodating cavity toward the female head, the cable sleeve can drive the end of the snap-in end to shrink, thereby further pressing the male head and the female head, making the connection between the two tighter.

[0020] In a second aspect, the present application provides a method for detecting a coaxial connector for cable connection, using the following technical solution: A method for detecting a coaxial connector for cable connection is applied to detect the above-mentioned coaxial connector for cable connection, comprising: Get the surface image information of the male connector; Determine reference point features from a preset reference point feature library according to surface image information; Controlling a preset clamping device to place the male head at a preset starting position of the test bench with the reference point feature facing upward; Controlling a preset toggle device to toggle the male head according to a preset toggle force to drive the male head to roll, and obtaining a first top view image of the male head after the male head is stationary; After the male connector is reset, the male connector is moved by increasing the force of the movement by a preset increment, and a secondary top view image of the male connector is obtained again; Based on the inconsistency between the first overhead image and the second overhead image, the detection is completed and a qualified prompt is output; If the first top view image and the second top view image are consistent, it is defined as a defective product. The male connector is inspected using the preset defective product cause determination method, and a defective product prompt is output.

[0021] By adopting the above technical solution, whether the male head is eccentric is determined by repeatedly moving the male head. If the male head remains in the same position each time when it is stationary, it means that the male head is eccentric, and the male head is determined to be a defective product. The detection method is highly efficient.

[0022] Optionally, methods for determining the cause of defective products include: Obtaining end face image information of the male connector shell; Identify the end face image information and analyze to obtain the end face profile features; Determine the end face radius of the product from a preset product database according to preset male connector model information; Generate circular contour features based on the end face radius of the product; If and only if the end face contour feature is inconsistent with the circular contour feature, a contour abnormality prompt is output, and the shortest diameter between the axis and the end face contour is determined based on the end face contour feature; Determine the diameter length adjustment value according to the end face radius and the shortest diameter length of the product, and match the opening force of the preset circle-bearing device according to the diameter length adjustment value; The rounding device is controlled according to the opening force to open the shell of the male head to correct it into a round shape.

[0023] Optionally, the method for determining the cause of defective products also includes: When the end face profile feature is consistent with the circular profile feature, the conductive pin feature and the conductive pin position are determined according to the end face image information and a preset pin feature library; Determine the image shape type according to the end face image information and the conductive pin features, the image shape type includes point shape and line shape; Based on the point shape, the detection is completed; Based on the line shape, it is defined as the pin tilt, the pin tilt prompt is output, and the overall pin image of the conductive pin feature is obtained; Determine the pin portion feature and the mounting portion feature of the conductive pin feature according to the overall pin image, and analyze whether the pin portion feature and the mounting portion feature are coaxial according to the overall pin image recognition; Based on the different axes, the tilt angle is determined according to the conductive pin characteristics and the preset axis position, and the preset straightening device is controlled according to the tilt angle to straighten the pin portion characteristics of the conductive pin position; Based on the coaxiality, a preset pressing device is controlled with a preset pressing force to press the preset insulating pads on both sides of the mounting portion feature; The puncture needle heated to a preset melting temperature is controlled to pierce the insulating pad at a preset piercing depth to heat and fuse the insulating pads on both sides of the mounting portion feature.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: When the male head and the female head are matched, the side opening on the female head shell can be opened by moving the sliding sleeve. At this time, the male head is directly inserted into the accommodating cavity from the side wall of the female head radially. When the male head is in the accommodating cavity, the side opening is covered by the side cover, and finally the sliding sleeve is reset. The cable connection is carried out by the above structure. Since the side wall is blocked by the side opening and the sliding cover, the male head and the female head are not easy to be disengaged, and the above male head and female head match mode is easy to disassemble and assemble without complicated steps; by driving the rotating ring to rotate, the sliding sleeve can be reciprocated between the locked state and the unlocked state, and the fixed seat and the rotating ring can rotate relatively. When the card strip is inserted into the unlocking card slot, the sliding sleeve can be locked in the unlocked state, which is convenient for the disassembly and assembly of the coaxial connector; when the sliding sleeve is directly driven to slide, the fixed seat and the rotating ring will not rotate relative to each other. At this time, when the sliding sleeve is pushed to the unlocked state, it will not be locked in the unlocked state, so that the sliding sleeve can be automatically reset when it is released. This method can be used to check the connection status of the coaxial connector, and it will automatically lock after the check is completed, which is relatively convenient. By toggling the male connector multiple times, it can be determined whether the male connector is eccentric. If the male connector remains in the same position each time it is stationary, it means that the male connector is eccentric, and the male connector is determined to be a defective product. The detection method is highly efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] An embodiment of the present application discloses a coaxial connector for cable connection.

[0028] Reference Figure 1 and Figure 2 The coaxial connector for cable connection includes a male head 1 and a female head 2 matched with the male head 1. The male head 1 has a conductive pin 3, and the cable is connected to the male head 1 by a threaded connection and communicates with the conductive pin 3. The female head 2 has a conductive pin seat 4, and the cable is connected to the female head 2 by a threaded connection and communicates with the conductive pin seat. When the male head 1 is matched with the female head 2, the end of the conductive pin 3 is inserted into the conductive pin seat 4 to achieve the connection between the two cables.

[0029] The male connector 1 includes a snap-in end 11 for cooperating with the female connector 2 and a mounting end 12 for cable installation, and the conductive pin 3 is located in the snap-in end 11. The snap-in end 11 has a limiting ring 13 in a ring shape.

[0030] Reference Figure 2 and Figure 3 The female connector 2 includes a female connector housing 21 , a cable sleeve 22 , a sliding sleeve 23 and a reset assembly 24 .

[0031] The female housing 21 is a hollow cylinder with openings at both ends. A side opening 211 is provided on the side wall of the female housing 21. The side opening 211 penetrates the inner cavity of the female housing 21, and the circumferential angle of the side opening 211 is 180°. In order to cover the side opening 211, the female housing 21 is provided with a side cover 212 at the side opening 211. One side of the side cover 212 is rotatably connected to the female housing 21 through a hinge. The other end of the side cover 212 is fixed to the female housing 21 through a fixing assembly 5.

[0032] Reference Figure 3 and Figure 4 The fixing assembly 5 includes a fixing rod 51 and a driving spring 52. The female housing 21 is provided with an insertion slot 213, and the end of the female housing 21 is provided with a mounting channel 215 connected with the insertion slot 213, and the mounting channel 215 is perpendicular to the insertion slot 213. The fixing rod 51 is slidably installed in the mounting channel 215, and a fixing block 53 facing the insertion slot 213 is provided on the fixing rod 51, and the fixing block 53 has a guiding inclined surface 531 facing the insertion slot 213. The driving spring 52 is provided in the mounting channel 215 and drives the fixing rod 51 to always have a tendency to return to the outside of the mounting channel 215.

[0033] An insertion block 214 that can be inserted into the insertion slot 213 is disposed on one side of the side cover 212 , and a placement slot for the fixing block 53 to be inserted is formed on the insertion block 214 .

[0034] When the side cover 212 covers the side opening 211 so that the insertion block 214 enters the insertion slot 213, the end of the insertion block 214 abuts against the guide slope 531 of the fixing block 53. When the insertion block 214 is pressed down, the insertion block 214 drives the fixing block 53 and the fixing rod 51 to slide in the installation channel 215, and the fixing block 53 is misaligned with the insertion slot 213. After the insertion block 214 completely enters the insertion slot 213, the fixing rod 51 slides out of the installation channel 215 driven by the return spring 243, and the fixing block 53 can be stuck in the arrangement slot to lock the insertion block 214 in the insertion slot 213 and the side cover 212 is locked and connected to the female housing 21.

[0035] When the side cover 212 needs to be opened, the fixing rod 51 is pressed at the end of the female head shell 21 , and the fixing rod 51 can slide, and the fixing block 53 can withdraw from the arrangement groove, and the insertion block 214 can withdraw from the insertion groove 213 .

[0036] Reference Figure 2 and Figure 3The cable sleeve 22 is used for fixing the cable, and the cable sleeve 22 is slidably installed in the inner cavity of the female housing 21. When the cable sleeve 22 slides, the inner cavity of the female housing 21 forms a receiving cavity 216 at the end of the cable sleeve 22, and the receiving cavity 216 is directly opposite to the side opening 211, and the receiving cavity 216 is used for installing the male connector 1.

[0037] Reference Figure 3 The sliding sleeve 23 is a hollow cylinder with two ends, and the sliding sleeve 23 is sleeved and slidably installed on the outer side of the female shell 21. The sliding sleeve 23 is connected to the cable sleeve 22 through a connecting structure 6, so that when the sliding sleeve 23 slides on the female shell 21, the sliding sleeve 23 can slide synchronously with the cable sleeve 22 in the inner cavity of the female shell 21. The connecting structure 6 includes a connecting block 61, and the connecting block 61 is circumferentially arranged on the outer wall of the cable sleeve 22. The inner wall of the sliding sleeve 23 is provided with an entry groove 62 along the length direction, and a plurality of entry grooves 62 are circumferentially arranged, and the number of entry grooves 62 corresponds to the connecting block 61. The inner wall of the sliding sleeve 23 is also provided with a fixed groove 63 in the circumferential direction, and the fixed groove 63 is connected to the tail of the entry groove 62 and is perpendicular to the entry groove 62.

[0038] During installation, the connecting block 61 is first inserted from the entry slot 62 and slid into the fixing slot 63, and then the sliding sleeve 23 and the cable sleeve 22 are installed together on the female housing 21. In order to enable the cable sleeve 22 to move in the inner cavity of the female housing 21, a sliding slot 217 for the connecting block 61 to slide is provided on the side wall of the female housing 21, and the sliding slot 217 passes through the inner and outer surfaces of the female housing 21.

[0039] Furthermore, the sliding groove 217 is misaligned with the entry groove 62 , so that the female housing 21 can lock the connecting block 61 in the fixing groove 63 of the sliding sleeve 23 .

[0040] Reference Figure 2 and Figure 3 In this embodiment, the sliding sleeve 23 has a locked state and an unlocked state. When the sliding sleeve 23 is in the unlocked state, the sliding sleeve 23 slides in a direction away from the male connector 1 and drives the cable sleeve 22 to slide in the inner cavity of the female connector housing 21. At this time, the sliding sleeve 23 can give way to the side cover 212 so that the side cover 212 can be opened. When the side cover 212 is opened, the snap-in end 11 of the male connector 1 can be snapped into the accommodating cavity 216 in the radial direction.

[0041] When the sliding sleeve 23 is in the locked state, the side cover 212 covers the side opening 211 and locks the snap-in end 11 of the male connector 1 in the accommodating cavity 216. The sliding sleeve 23 slides to the outside of the side cover 212 in the direction close to the male connector 1 and locks the side cover 212 in the side opening 211. When the sliding sleeve 23 slides, the cable sleeve 22 is synchronously driven to slide in the direction close to the male connector 1 and the conductive pin 3 is docked with the conductive pin seat 4.

[0042] Reference Figure 2 and Figure 3 Furthermore, in order to prevent the snap-in end 11 from axially disengaging after being snapped into the accommodating cavity 216, the female housing 21 is provided with a sealing ring 218 on the inner wall of the accommodating cavity 216. The sealing ring 218 is annular. When the snap-in end 11 is located in the accommodating cavity 216, the limiting ring 13 on the snap-in end 11 can form a limit with the sealing ring 218.

[0043] Reference Figure 1 and Figure 2 Furthermore, a through shrinkage groove 111 is circumferentially provided at one end of the snap-in end 11 close to the female connector 2. The through shrinkage groove 111 is axially provided and penetrates the inner and outer surfaces of the snap-in end 11. The cable sleeve 22 has a flared portion 221 on one side close to the snap-in end 11. When the conductive plug 3 is matched with the conductive needle seat 4, the snap-in end 11 is inserted into the cable sleeve 22 and moves along the surface of the flared portion 221 of the cable sleeve 22, so that the gap through the shrinkage groove 111 is reduced and the end diameter of the snap-in end 11 is reduced as the insertion depth increases, thereby pressing the conductive plug 3 and the conductive needle seat 4 tightly.

[0044] Reference Figure 2 and Figure 5 Furthermore, when the insertion end 11 is inserted into the receiving groove, in order to allow the conductive pin 3 and the conductive needle seat 4 to be closely connected, a pressing assembly 7 is provided in the receiving cavity 216 to drive the male plug 1 to be axially pressed against the female plug 2. The pressing assembly 7 includes a pressing ring 71 and a pressing spring 72, the pressing spring 72 is circumferentially connected to the inner side of the sealing ring 218, and the pressing ring 71 is connected to one end of the pressing spring 72 away from the sealing ring 218.

[0045] A limiting groove 73 is formed on the inner wall of the accommodating chamber 216, and a contact piece 74 is rotatably arranged in the limiting groove 73. The contact piece 74 is driven by a compression spring and always extends into the accommodating chamber 216 and abuts against the clamping ring 71, so that the clamping ring 71 and the clamping spring 72 are always in a compressed state when the clamping end 11 is not installed in the accommodating chamber 216.

[0046] When the snap-in end 11 is installed in the accommodating cavity 216, the snap-in end 11 drives the abutment sheet 74 to be compressed into the limiting groove 73. At this time, the clamping ring 71 abuts against the limiting ring 13 of the snap-in end 11 due to the lack of restriction of the abutment sheet 74, so that the clamping spring 72 drives the conductive pin 3 and the conductive pin seat 4 to be further inserted.

[0047] Reference Figure 2 and Figure 3The reset assembly 24 includes a fixed seat 241, a rotating ring 242 and a reset spring 243. The fixed seat 241 is installed at the end of the female head shell 21 away from the male head 1. The rotating ring 242 is a hollow cylinder with two ends open, which is sleeved on the female head shell 21 and rotatably connected to the fixed seat 241. The inner diameter of the rotating ring 242 is larger than the outer diameter of the female head shell 21, so that a telescopic chamber 244 is formed between the rotating ring 242 and the female head shell 21. One end of the sliding sleeve 23 extends into the telescopic chamber 244 and can be telescopic in the telescopic chamber 244.

[0048] The return spring 243 is installed in the telescopic chamber 244, one end of which is connected to the sliding sleeve 23, and the other end is connected to the rotating ring 242. The return spring 243 drives the sliding sleeve 23 to always have a tendency to extend out of the telescopic chamber 244 and be in a locked state.

[0049] Reference Figure 3 and Figure 6 Furthermore, a locking block 231 is circumferentially arranged on the outer wall of the sliding sleeve 23, and a locking groove 2421, an unlocking groove 2422, and a connecting channel 2423 connecting the locking groove 2421 and the unlocking groove 2422 are arranged on the inner wall of the rotating ring 242. The locking groove 2421, the unlocking groove 2422, and the connecting channel 2423 are all used for the locking block 231 to be arranged or slided, wherein the locking block 231 is located in the locking groove 2421 when the sliding sleeve 23 is in the locked state, and the locking block 231 is located in the unlocking groove 2422 when the sliding sleeve 23 is in the unlocked state, and the locking block 231 slides in the connecting channel 2423 when the sliding sleeve 23 switches between the locked state and the unlocked state.

[0050] In this embodiment, adjacent locking grooves 2421 are connected through the connecting channel 2423. The connecting channel 2423 includes an unlocking path 2424 and a locking path 2425, wherein the unlocking path 2424 connects the locking groove 2421 and the unlocking groove 2422 and is obliquely opened, and the locking path 2425 connects the unlocking groove 2422 and the adjacent locking groove 2421 and is opened along the axial direction of the rotating ring 242.

[0051] Reference Figure 3 , Figure 6 and Figure 7In order to enable the sliding sleeve 23 to be locked when it switches to the unlocking state, that is, the locking block 231 is located in the unlocking groove 2422, a clamping strip 2411 corresponding to the unlocking groove 2422 is circumferentially arranged on the top of the fixing seat 241, and an unlocking clamping slot 245 for the clamping strip 2411 to be clamped in and for the locking block 231 to be locked in the unlocking groove 2422, and a sliding clamping slot 246 for the locking block 231 to slide in the connecting channel 2423 is provided at the bottom of the rotating ring 242. The circumferential angle of the sliding clamping slot 246 is greater than the circumferential angle of the unlocking clamping slot 245 to accommodate the movement of the locking block 231 in the connecting channel 2423.

[0052] By driving the rotating ring 242 to rotate, the sliding sleeve 23 switches from the locked state to the unlocked state, and the locking block 231 moves from the locking groove 2421 to the unlocking groove 2422 along the unlocking path 2424. At this time, the clamping strip 2411 withdraws from the sliding slot and is clamped into the unlocking slot 245, so that the locking block 231 is fixed in the unlocking slot 2422. In this state, the sliding sleeve 23 is not easy to reset, thereby facilitating the matching installation of the male head 1 and the female head 2.

[0053] Continue to drive the rotating ring 242 to rotate, the clamping strip 2411 withdraws from the unlocking slot 245 and enters the sliding slot, and the locking block 231 can move from the unlocking slot 2422 along the locking path 2425 to the adjacent locking slot 2421. At this time, the sliding sleeve 23 switches from the unlocking state to the locking state under the drive of the return spring 243.

[0054] The above-mentioned method of directly driving the rotating ring 242 to rotate to realize the movement of the sliding sleeve 23 can lock the sliding sleeve 23 in the unlocked state. Since the locking path 2425 is opened along the axial direction of the rotating ring 242, when the sliding sleeve 23 is directly driven to retract, the fixed seat 241 and the rotating ring 242 will not rotate relative to each other, so that the sliding sleeve 23 will not be locked in the unlocked state. This method can be used to check the internal situation of the coaxial connector, and the sliding sleeve 23 can automatically reset after the inspection.

[0055] Reference Figure 3 Furthermore, the elastic force of the return spring 243 can be adjusted to adapt to the fatigue of the return spring 243. The fixed seat 241 is circumferentially provided with a limiting adjustment block 2412 that is inserted into the sliding groove 217, and the limiting adjustment block 2412 is provided with an adjustment tooth 2413. The sliding groove 217 has a gear slot 219 for selectively inserting the adjustment tooth 2413 at intervals along the length direction.

[0056] When the limiting adjustment block 2412 is inserted into the sliding groove 217 , the fixing seat 241 is pressed to make the adjustment teeth 2413 of the limiting adjustment block 2412 slide in the sliding groove 217 to select the shift groove 219 , thereby adjusting the elastic force of the return spring 243 .

[0057] Based on the same inventive concept, an embodiment of the present invention provides a method for detecting a coaxial connector for cable connection. Since the shape and pin arrangement of the coaxial connector need to meet the requirements when the male head 1 and the female head 2 of the coaxial connector are matched, the coaxial connector needs to be detected after the product production is completed. In this embodiment, the male head 1 is detected, and image recognition is used to detect whether the outline of the male head 1 is circular and whether the conductive pins 3 of the male head 1 are coaxially arranged, and adjustments are made after problems are found.

[0058] Reference Figure 8 A method for detecting a coaxial connector for cable connection comprises the following steps: Step S100: obtaining surface image information of the male connector 1 .

[0059] The surface image information refers to the image information of the male connector 1 obtained by the camera when the device places the male connector 1 on the test bench, which includes all the characteristic information of the surface of the male connector 1. The camera is set on the top of the test bench and can take pictures of the products on the test bench to obtain parameters.

[0060] Step S101: determining reference point features from a preset reference point feature library according to surface image information.

[0061] The reference point feature refers to a reference point on the surface of the male plug 1 that has an identification meaning and can indicate the placement state of the male plug 1 when it is currently stationary. The reference point feature is used to identify the state of the male plug 1 in the current position, so that the male plug 1 can be placed in the current position in the same state during the next round of detection.

[0062] The reference points are a database obtained by machine learning that contains all images in the male head 1 that can be used as reference points, which will not be described in detail here.

[0063] After the surface image information is acquired, the reference point features on the surface of the male head 1 at the current position that match the reference point feature library can be identified from the surface image information.

[0064] Step S102: Control the preset clamping device to place the male plug 1 at a preset starting position of the test bench with the reference point feature facing upward.

[0065] The clamping device is used to clamp the male connector 1 so as to place the male connector 1 on the test bench.

[0066] The starting position of the test bench is the initial placement position when the male plug 1 starts testing. In this embodiment, the male plug 1 needs to be placed at the starting position of the test bench to test the male plug 1, and each round of testing starts at the starting position of the test bench.

[0067] The purpose of the reference point feature facing upward is to fix the position of the reference point feature. At the beginning of each round of detection of the male head 1, the reference point feature is located at the same position, so that the position state of the male head 1 at the beginning of the test is consistent.

[0068] Step S103: controlling a preset toggle device to toggle the male head 1 according to a preset toggle force to drive the male head 1 to roll, and obtaining a first top view image of the male head 1 after the male head 1 is stationary.

[0069] The toggle device is used to toggle the male connector 1 so that the male connector 1 can roll. The toggle force is the force set by the technician when the toggle device toggles the male connector 1, which will not be described in detail here.

[0070] The first top-view image refers to an image of the male head 1 obtained by photographing the male head 1 at the top of the male head 1 through a camera. The image of the male head 1 is the first image taken by the camera after the male head 1 starts to be detected.

[0071] Step S104: after resetting the male connector 1 , the male connector 1 is moved by increasing the force of the movement by a preset increment, and a secondary top view image of the male connector 1 is obtained again.

[0072] The secondary top-view image refers to the second image obtained by the camera at the same position after obtaining the first top-view image when the male connector 1 performs a second round of repeated testing.

[0073] In this embodiment, after obtaining the first overhead view image, the male head 1 is reset back to the starting position of the test bench and the position of the reference point feature is also reset. Then, the male head 1 is toggled for the second time by the toggle device, and the second overhead view image is obtained again. By comparing the front and back images to determine whether the male head 1 is stationary in the same position, it is determined whether the male head 1 is eccentric.

[0074] In order to avoid the situation that the male plug 1 pushed out by the same pulling force may be stationary in the same position regardless of whether it is eccentric, the pulling force is changed in the second repeated detection. The preset increase range is the amount of change of the pulling force set by the technician, which will not be repeated here.

[0075] Step S1041: Based on the inconsistency between the first top-view image and the second top-view image, the detection is completed and a qualified prompt is output.

[0076] If the male connector 1 is eccentric, its center of gravity is not on the central axis. At this time, no matter when the male connector 1 is stationary, its center of gravity is at the lowest point when it is stationary. Therefore, the male connector 1 will be stationary on the test bench in the same state, and the reference point feature position will stop at the same position during each test. If the male connector 1 is a qualified product, that is, the center of gravity is on the central axis, the male connector 1 will be stationary in different positions when it is toggled with different toggling forces.

[0077] In a detection environment where the starting position and the reference point feature position of the male head 1 are the same and the pulling force is different, if the first top view image and the second top view image are consistent, it means that the male head 1 is a qualified product.

[0078] Step S1042: Based on the consistency between the first top view image and the second top view image, it is defined as a defective product, the male head 1 is inspected using a preset defective product cause determination method, and a defective product prompt is output.

[0079] In the detection environment where the starting position and the reference point feature position of the male head 1 are the same and the pulling force is different, if the first top view image and the second top view image are inconsistent, it means that the male head 1 is eccentric, and the male head 1 is defined as a defective product. Then the system will re-test the male head 1 to determine the cause of the defect and make corrections. The method for determining the cause of defective products will not be described in detail here, but will be described in detail in the subsequent embodiments.

[0080] The method for determining the cause of defective products includes the following steps: Step S200: Acquire the end surface image information of the shell of the male connector 1.

[0081] The end face image information refers to the image of the male connector 1 shell obtained when the camera is photographed perpendicularly to the end face of the male connector 1 shell, and the end face image information is an orthographic projection view.

[0082] Step S201: Identify end face image information and analyze to obtain end face contour features.

[0083] The end face profile feature refers to the profile of the end face of the male connector 1 shell. The end face profile of a normal and qualified male connector 1 shell is circular.

[0084] The end face profile features can be identified and analyzed from the end face image information.

[0085] Step S202: determining the product end face radius from a preset product database according to preset male connector 1 model information.

[0086] The male connector model information is the standard model of the male connector 1 to be detected. All parameter information of the male connector 1 can be queried according to the male connector model information, which will not be described in detail here.

[0087] The product end face radius refers to the contour radius of the end face of a specific model of male plug 1.

[0088] The product database is a database including parameter information of all coaxial connectors, including male connector model information of male connector 1 and product end face radius of male connector 1. The product end face radius can be matched from the product database according to the male connector model information.

[0089] Step S203: Generate a circular contour feature according to the end face radius of the product.

[0090] The circular profile feature is a circular feature model used for profile shape comparison. After the end face radius of the product is determined, the circular profile feature for reference comparison can be obtained based on the end face radius of the product.

[0091] Step S204: If and only if the end face contour feature is inconsistent with the circular contour feature, output a contour abnormality prompt, and determine the shortest diameter between the axis and the end face contour according to the end face contour feature.

[0092] The end face contour feature is overlapped and compared with the circular contour feature. If the two are inconsistent, it means that the end face of the male plug 1 to be detected is not circular, and it has a certain deformation and produces eccentricity. At this time, the system will issue a prompt that the contour of the male plug 1 is abnormal.

[0093] The shortest path length refers to the shortest distance between a point on the end face profile feature and the center of a circle. By determining the shortest path length, in subsequent embodiments, the point on the end face profile feature closest to the center of a circle needs to be corrected to a distance from the center of the circle equal to the end face radius of the product.

[0094] Step S205: determining a diameter adjustment value according to the end face radius and the shortest diameter of the product, and matching a preset opening force of the rounding device according to the diameter adjustment value.

[0095] The diameter length adjustment value refers to the adjustment amount required to correct the point with the shortest diameter length to a distance from the center of the circle equal to the end face radius of the product. The diameter length adjustment value is the difference between the end face radius of the product and the shortest diameter length.

[0096] The rounding device is used to expand the contour of the end face of the eccentric male head 1 so that the contour expands in the circumferential direction until it is a circle as a whole. The expansion force is the force applied by the rounding device to the end face of the male head 1. The greater the force applied, the greater the expansion distance. The expansion force is proportional to the diameter length adjustment value. The greater the diameter length adjustment value, the greater the expansion force.

[0097] When the point with the shortest diameter on the contour of the male connector 1 is stretched to a distance from the center of the circle equal to the end face radius of the product, other positions on the contour of the male connector 1 can be deformed adaptively and eventually become a circle.

[0098] Step S206: Controlling the rounding device to open the shell of the male plug 1 to correct it into a round shape according to the opening force.

[0099] After the opening force is determined, the system controls the rounding device to extend into the male head 1 and open the end face of the male head 1, so that the end face of the male head 1 is finally round, and the radius of the end face contour is the end face radius of the product.

[0100] The reason why the male plug 1 product is defective is not only because the shell is deformed and eccentric, but also because the conductive pin 3 inside the male plug 1 is abnormal. The method for determining the cause of the defective product also includes the following steps: Step S300: When the end face profile feature is consistent with the circular profile feature, the conductive pin feature and the conductive pin position are determined according to the end face image information and a preset pin feature library.

[0101] The end face contour feature is overlapped and compared with the circular contour feature. If the two are consistent, it means that the end face of the male connector 1 to be tested is circular. Therefore, the circular shape that causes the male connector 1 to be eccentric is not the deformation of the male connector 1 shell, but the conductive pin 3 inside the male connector 1 may be tilted, causing the male connector 1 to be eccentric.

[0102] The pin feature library is a database containing images of the conductive pins 3 obtained by machine learning, which will not be described in detail here.

[0103] The conductive pin feature is the conductive pin 3 in the inner cavity of the male connector 1 for docking with the conductive pin holder 4. The conductive pin position is the position of the conductive pin feature in the inner cavity of the male connector 1.

[0104] By identifying and matching the end face image information and the pin feature library, the conductive pin features and conductive pin positions can be determined.

[0105] Step S301: determining the image shape type according to the end surface image information and the conductive pin features, the image shape types including point shape and line shape.

[0106] Since the end face image information is an orthographic projection view, if the conductive pin feature is normal, the conductive pin feature is displayed as a point in the end face image information, and if the conductive pin feature is tilted, the conductive pin feature is displayed as a line in the end face image information. According to the end face image information and the conductive pin feature, the image shape type displayed by the conductive pin feature can be determined.

[0107] Step S3011: Complete detection based on points.

[0108] If the image shape type is dot-shaped, it means that the conductive pin 3 of the male connector 1 is also normal. In this case, the reason for the eccentricity of the male connector 1 may be the material of the male connector 1 itself. This situation cannot be directly solved by physical methods, so the male connector 1 is directly discarded.

[0109] Step S3012: Based on the line shape, define it as pin tilt, output the pin tilt prompt, and obtain the overall pin image of the conductive pin feature.

[0110] If the image shape type is a line, it means that the conductive pin 3 of the male connector 1 is tilted, and the system needs to clarify the situation of the conductive pin 3. At this time, the angle of the camera is adjusted to obtain the overall pin image of the conductive pin feature. The overall pin image is not an orthographic projection view, which includes the complete image of the conductive pin 3. The conductive pin 3 includes a pin portion and a mounting portion, and both the pin portion and the mounting portion are included in the overall pin image.

[0111] Step S302: determining the pin portion feature and the mounting portion feature of the conductive pin feature according to the overall pin image, and determining whether the pin portion feature and the mounting portion feature are coaxial according to the overall pin image recognition and analysis.

[0112] After obtaining the overall image of the plug, the image can be identified to determine the plug part features and the installation part features of the conductive plug 3, and then the system determines whether the axes of the two are coaxial through image recognition.

[0113] There are two situations in which the conductive pin 3 is tilted. One is that when the conductive pin 3 is installed on the male connector 1, the installation feature of the installation part is qualified but the pin part feature is tilted. The other situation is that when the conductive pin 3 is installed on the male connector 1, the insulating pads at both ends of the pin part feature can press the pin part feature tightly, causing the conductive pin 3 to tilt as a whole.

[0114] In this embodiment, the insulating pad is installed in the male connector 1 to install and press the conductive pin 3, and the insulating pad is made of a transparent material, so the conductive pin 3 can be identified as a whole in the overall pin image.

[0115] By analyzing whether the two axes are coaxial, the above two situations can be distinguished and targeted solutions can be provided for the two situations.

[0116] Step S3021: Based on the different axes, determine the inclination angle according to the conductive pin characteristics and the preset axis position, and control the preset straightening device to straighten the pin portion characteristics of the conductive pin position according to the inclination angle.

[0117] If the pin feature and the mounting feature are not coaxial, it means the first situation mentioned above, where the pin feature is tilted while the mounting feature is installed normally.

[0118] The straightening device is used to straighten the conductive pin 3 , and the straightening device comprises a clamping jaw, which can clamp the conductive pin 3 at the conductive pin position and tilt it at a certain angle.

[0119] The tilt angle is the angle at which the conductive pin 3 deviates from the axis position, and is also the angle that needs to be corrected when the straightening device straightens the conductive pin 3 .

[0120] After determining the tilt angle, the system controls the straightening device to extend to the conductive pin position to straighten the conductive pin 3.

[0121] Step S3022: Based on the coaxiality, a preset pressing device is controlled with a preset pressing force to press the preset insulating pads on both sides of the mounting portion feature.

[0122] If the pin feature and the installation feature are coaxial, it indicates the second situation mentioned above, that is, when the conductive pin 3 is installed, the insulating pad does not press the conductive pin 3 tightly, causing the conductive pin 3 to be tilted as a whole. At this time, straightening by a straightening device is only a temporary solution and does not address the root cause, and the insulating pad needs to be adjusted.

[0123] The pressing device is used to press the insulating pad. The pressing device has two pressing parts. Each pressing part can extend from two ends of the male connector 1 and press the insulating pad.

[0124] The clamping force is the force applied by the clamping device set by the technician to clamp the insulating pad. The applied force is not easy to damage the conductive pin 3, and will not be elaborated here.

[0125] After the insulating pads on both sides of the mounting feature are squeezed by the clamping device, the conductive pin 3 can be reset to the axial position. At this time, the conductive pin 3 needs to be further fixed.

[0126] Step S303: Control the puncture needle heated to a preset melting temperature to pierce the insulating pad at a preset piercing depth to heat and fuse the insulating pads on both sides of the mounting portion feature.

[0127] The melting temperature is a temperature capable of melting the insulating pad. The puncture needle is used to pierce the insulating pads on both sides of the mounting portion feature and use the high temperature it carries to fuse and fix the two insulating pads at the piercing position.

[0128] The penetration depth is a depth set by technicians according to the thickness of the insulating pad. The puncture needle is controlled to penetrate the insulating pad with the penetration depth, and can penetrate two layers of insulating pads. No further details are given here.

[0129] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
