Description

Technical Field

[0001] The present 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 component used to connect the ends of two cables to ensure that the ends of the two cables are connected and conductive.

[0003] Coaxial connectors have a male and female connector that are joined together to form a mating pair. In the prior art, the male and female connectors are plugged into each other and each connector has threads that further secure the connector. This threaded connection requires tightening with tools, which is inconvenient. Furthermore, if the threads rust during use, the male and female connectors may become difficult to separate, hindering their disassembly. This requires further improvement. 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:

[0006] A coaxial connector for cable connection, comprising a female connector and a male connector mated with the female connector, characterized in that the male connector has a snap-in end; the female connector comprises a female connector housing, a cable sleeve slidably mounted within the inner cavity of the female connector housing for mounting a cable, a sliding sleeve sleeved and slidably mounted on the outer side of the female connector housing, and a reset assembly for driving the sliding sleeve to reset;

[0007] An accommodating cavity for the male connector to be inserted and placed is formed between the end of the cable sleeve close to the male connector and the female connector housing. A side opening extending through 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.

[0008] 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.

[0009] By adopting this technical solution, when the male connector and female connector mate, the side opening on the female connector housing can be opened by moving the sliding sleeve. The male connector can then be directly inserted radially into the accommodating cavity from the side wall of the female connector. Once the male connector is in the accommodating cavity, the side opening is closed with the side cover, and the sliding sleeve is finally reset. This structure makes cable connection difficult because the side walls are blocked by the side opening and the sliding cover, making it difficult for the male and female connectors to disengage. Furthermore, this method of mating the male and female connectors makes assembly and disassembly relatively easy, without complicated steps.

[0010] 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; the inner wall of the sliding sleeve is provided with an entry groove for the connecting block to slide into along the length direction, and a fixed groove for the connecting block to be clamped into is vertically provided at the tail of the entry groove; the female head shell is provided with a sliding groove for the connecting block to slide along the length direction; the sliding groove and the entry groove are staggered so that the female head shell can lock the connecting block in the fixed groove.

[0011] By adopting the above technical solution, by connecting the sliding sleeve to the cable sleeve, when the sliding sleeve switches from a locked state to an unlocked state, the cable sleeve can also move within the female connector housing, so that when the male connector and the female connector mate, the accommodating cavity has a larger space for the male connector to be inserted and installed. In addition, when the sliding sleeve slides, the cable sleeve of the female connector can also be pressed against the male connector, ensuring a tight connection between the two.

[0012] 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 is formed between the rotating ring and the female housing for the sliding groove to be inserted and extended; the reset spring is arranged in the telescopic chamber and one end of which is connected to the end of the sliding sleeve;

[0013] The fixing seat is circumferentially provided with a limiting adjustment block that is engaged with 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 gear slots spaced apart along the length direction for the adjustment teeth to be selectively engaged to adjust the elastic force of the return spring.

[0014] By adopting this technical solution, by pressing the fixed seat, the adjustment block is restricted from sliding within the sliding groove, causing the adjustment tooth to switch positions within the shift groove. The elastic force of the return spring can be adjusted when the adjustment tooth switches positions. If the return spring's elasticity decreases due to prolonged pressure on the coaxial connector's sliding sleeve, this result allows the return spring to be re-preloaded, ensuring that the return spring always exerts a strong pressure on the sliding sleeve, locking the side opening and side cover, and preventing the coaxial connector from opening easily during use.

[0015] Optionally, a locking block is provided on the outer circumference of the sliding sleeve; 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 allowing the locking block to slide;

[0016] 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;

[0017] The top of the fixing seat is provided with a snap-fitting strip; the bottom of the rotating ring is provided with an unlocking slot for the snap-fitting strip to be snapped in 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.

[0018] 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 relative to each other. 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.

[0019] When the sliding sleeve is directly driven to slide, the fixed seat and rotating ring do 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 it will automatically reset when it is released. This method can be used to check the connection status of the coaxial connector, and automatically lock it after the inspection is completed, which is very convenient.

[0020] Optionally, the snap-in end is provided with a limiting ring in the circumference, and the accommodating cavity is provided with a sealing ring for limiting the snap-in end from axially dislodging; a pressing assembly for driving the male head to axially press against the female head is provided in the accommodating cavity; the pressing assembly includes a pressing ring and a pressing spring circumferentially connected to the pressing ring, and the other end of the pressing spring is connected to the sealing ring;

[0021] The inner wall of the accommodating cavity is provided with a limiting groove and an abutting piece is rotatably provided in the limiting groove, and the abutting piece is driven by a compression spring to extend out of the limiting groove and abut against the clamping ring;

[0022] 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.

[0023] By adopting the above technical solution, when the snap-in end of the male head is installed into the accommodating cavity, the compression spring can drive the compression 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 compression spring, making the connection between the two tighter, the conductive effect better, and less likely to have poor contact.

[0024] 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;

[0025] The fixing assembly includes a fixing rod slidably installed in the installation channel and a driving spring that drives 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 guide inclined surface is provided on the side of the fixing block facing the insertion slot; the insertion block has an arrangement groove for the fixing block to be inserted.

[0026] By adopting the above technical solution, 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 tightly into the accommodating cavity of the female head.

[0027] Optionally, a through shrinkage groove is circumferentially provided on the snap-in end, and a flared portion is provided on one side of the cable sleeve close to the snap-in end.

[0028] By adopting the above technical solution, when the snap-in end is inserted into the accommodating cavity toward the female end, the cable sleeve can drive the end of the snap-in end to shrink, thereby further pressing the male end and the female end, making the connection between the two tighter.

[0029] In a second aspect, the present application provides a method for detecting a coaxial connector for cable connection, which adopts the following technical solution:

[0030] A method for detecting a coaxial connector for cable connection is applied to detect the above-mentioned coaxial connector for cable connection, comprising:

[0031] Get the surface image information of the male connector;

[0032] Determining reference point features from a preset reference point feature library based on surface image information;

[0033] 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;

[0034] 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;

[0035] After resetting the male connector, increase the force of the push-pull operation by a preset increment and push the male connector to obtain a second top-view image of the male connector.

[0036] If the first overhead image and the second overhead image are inconsistent, the inspection is completed and a qualified prompt is output;

[0037] 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.

[0038] 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.

[0039] Optional methods for determining the cause of defective products include:

[0040] Obtain end face image information of the male connector shell;

[0041] Identify end face image information and analyze to obtain end face profile features;

[0042] Determine the product end face radius from a preset product database according to preset male connector model information;

[0043] Generate circular contour features based on the end face radius of the product;

[0044] If and only if the end face profile feature is inconsistent with the circular profile feature, a profile abnormality prompt is output, and the shortest diameter length between the axis and the end face profile is determined based on the end face profile feature;

[0045] Determine the diameter adjustment value according to the end face radius and the shortest diameter of the product, and match the opening force of the preset circle-supporting device according to the diameter adjustment value;

[0046] 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.

[0047] Optionally, the method for determining the cause of defective products also includes:

[0048] 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 the preset pin feature library;

[0049] Determine the image shape type according to the end face image information and the conductive pin features, where the image shape types include dot and line;

[0050] Based on point shape, complete the detection;

[0051] Based on the line shape, it is defined as pin tilt, the pin tilt prompt is output, and the overall pin image of the conductive pin feature is obtained;

[0052] Determine the pin portion feature and the mounting portion feature of the conductive pin feature based on the overall pin image, and determine whether the pin portion feature and the mounting portion feature are coaxial based on the overall pin image recognition and analysis;

[0053] 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;

[0054] Based on the coaxiality, a preset pressing device is controlled with a preset pressing force to squeeze the preset insulating pads on both sides of the mounting portion feature;

[0055] The puncture needle heated to a preset melting temperature is controlled to pierce the insulation pad at a preset piercing depth to heat and fuse the insulation pads on both sides of the mounting portion feature.

[0056] In summary, this application includes at least one of the following beneficial technical effects:

[0057] When the male connector and the female connector mate, the side opening on the female connector housing can be opened by moving the sliding sleeve. At this time, the male connector is directly inserted radially into the accommodating cavity from the side wall of the female connector. When the male connector 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 connector and the female connector are not easy to disengage because the side wall is blocked by the side opening and the sliding cover. In addition, the above-mentioned male connector and the female connector mate in a relatively easy way, without complicated steps. By driving the rotating ring to rotate, the sliding sleeve can be switched back and forth between a locked state and an unlocked state, and the fixed seat and the rotating ring can rotate relative to each other. When the card strip is engaged in the unlocking slot, the sliding sleeve can be locked in the unlocked state, which facilitates 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, the sliding sleeve will not be locked in the unlocked state when it is pushed to the unlocked state, so that it can 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

[0067] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to 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 intended to limit the present invention.

[0068] An embodiment of the present application discloses a coaxial connector for cable connection.

[0069] Reference Figure 1 and Figure 2 A coaxial connector for cable connection includes a male connector 1 and a female connector 2 that mates with the male connector 1. Male connector 1 includes a conductive pin 3, which is threaded onto the male connector 1 and communicates with the conductive pin 3. Female connector 2 includes a conductive pin holder 4, which is threaded onto the female connector 2 and communicates with the pin holder. When male connector 1 and female connector 2 are mated, the end of the conductive pin 3 is inserted into the conductive pin holder 4, connecting the two cables.

[0070] The male connector 1 includes a snap-in end 11 for mating with the female connector 2 and a mounting end 12 for cable installation. The conductive pin 3 is located inside the snap-in end 11. A limiting ring 13 is provided around the snap-in end 11. The limiting ring 13 is annular.

[0071] 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 .

[0072] The female connector housing 21 is a hollow cylinder with two open ends. A side opening 211 is defined on the sidewall of the female connector housing 21. This opening 211 extends into the inner cavity of the female connector housing 21 and extends at a 180° angle. To cover the opening 211, the female connector housing 21 is provided with a side cover 212. One side of the side cover 212 is hingedly connected to the female connector housing 21. The other end of the side cover 212 is secured to the female connector housing 21 via a fixing assembly 5.

[0073] Reference Figure 3 and Figure 4 The fixing assembly 5 includes a fixing rod 51 and a driving spring 52. The female connector housing 21 defines an insertion slot 213, and a mounting channel 215 is defined at the end of the female connector housing 21, communicating with the insertion slot 213. The mounting channel 215 is perpendicular to the insertion slot 213. The fixing rod 51 is slidably mounted within the mounting channel 215. A fixing block 53 is provided on the fixing rod 51, facing the insertion slot 213. The fixing block 53 has a guiding slope 531 on the side facing the insertion slot 213. The driving spring 52 is disposed within the mounting channel 215 and forces the fixing rod 51 to always return to the outside of the mounting channel 215.

[0074] An insertion block 214 that can be inserted into the insertion slot 213 is provided 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 .

[0075] When the side cover 212 covers the side opening 211, allowing the insertion block 214 to enter 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 downward, the insertion block 214 drives the fixing block 53 and the fixing rod 51 to slide within the installation channel 215. At this time, the fixing block 53 is misaligned with the insertion slot 213. After the insertion block 214 has fully entered the insertion slot 213, the fixing rod 51 slides out of the installation channel 215 under the drive of the return spring 243. At this time, the fixing block 53 can be snapped into the arrangement groove, thereby locking the insertion block 214 within the insertion slot 213 and locking the side cover 212 to the female connector housing 21.

[0076] 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 .

[0077] Reference Figure 2 and Figure 3 The cable sleeve 22 is used to secure the cable and is slidably mounted within the inner cavity of the female connector housing 21. When the cable sleeve 22 slides, the inner cavity of the female connector housing 21 forms a receiving cavity 216 at the end of the cable sleeve 22. The receiving cavity 216 is directly opposite the side opening 211 and is used to mount the male connector 1.

[0078] Reference Figure 3 The sliding sleeve 23 is a hollow cylinder with two ends. The sliding sleeve 23 is sleeved and slidably installed on the outside 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, which 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. There are multiple entry grooves 62 arranged circumferentially and the number of entry grooves 62 corresponds to the number of connecting blocks 61. The inner wall of the sliding sleeve 23 is also provided with a fixed groove 63 circumferentially. The fixed groove 63 is connected to the tail of the entry groove 62 and is perpendicular to the entry groove 62.

[0079] During installation, the connecting block 61 is first inserted through the entry slot 62 and slid into the fixing slot 63. The sliding sleeve 23 and the cable sleeve 22 are then installed together on the female connector housing 21. To allow the cable sleeve 22 to move within the inner cavity of the female connector housing 21, a sliding slot 217 is provided on the side wall of the female connector housing 21 for the connecting block 61 to slide. The sliding slot 217 extends through the inner and outer surfaces of the female connector housing 21.

[0080] 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 .

[0081] Reference Figure 2 and Figure 3 In this embodiment, the sliding sleeve 23 has a locked state and an unlocked state. When in the unlocked state, the sliding sleeve 23 slides away from the male connector 1, driving the cable sleeve 22 to slide within the inner cavity of the female connector housing 21. At this time, the sliding sleeve 23 can make way for the side cover 212, allowing it to open. When the side cover 212 is opened, the snap-in end 11 of the male connector 1 can be radially inserted into the accommodating cavity 216.

[0082] When the sliding sleeve 23 is locked, the side cover 212 covers the side opening 211 and locks the snap-in end 11 of the male connector 1 within the accommodating cavity 216. The sliding sleeve 23 slides toward the outside of the side cover 212, locking the side cover 212 within the side opening 211. As the sliding sleeve 23 slides, it simultaneously drives the cable sleeve 22 toward the male connector 1, allowing the conductive pins 3 to mate with the conductive pin holder 4.

[0083] Reference Figure 2 and Figure 3 Furthermore, to prevent the snap-in end 11 from axially dislodging after being inserted into the accommodating cavity 216, the female housing 21 is provided with a ring-shaped sealing ring 218 on the inner wall of the accommodating cavity 216. When the snap-in end 11 is located in the accommodating cavity 216, the retaining ring 13 on the snap-in end 11 can form a retaining position with the sealing ring 218.

[0084] Reference Figure 1 and Figure 2 Furthermore, a through-contraction groove 111 is circumferentially defined at the end of the snap-in end 11 near the female connector 2. The through-contraction groove 111 extends axially and penetrates the inner and outer surfaces of the snap-in end 11. The cable sheath 22 has a flared portion 221 on one side near the snap-in end 11. When the conductive pin 3 is mated with the conductive pin holder 4, the snap-in end 11 is inserted into the cable sheath 22 and moves along the surface of the flared portion 221 of the cable sheath 22. This causes the gap through the through-contraction groove 111 to narrow, and the diameter of the end of the snap-in end 11 to shrink as the insertion depth increases, thereby pressing the conductive pin 3 against the conductive pin holder 4.

[0085] Reference Figure 2 and Figure 5 Furthermore, when the snap-in end 11 is inserted into the receiving groove, a compression assembly 7 is provided in the receiving cavity 216 to axially compress the male connector 1 against the female connector 2 to ensure a tight connection between the conductive pin 3 and the conductive pin holder 4. The compression assembly 7 includes a compression ring 71 and a compression spring 72. The compression spring 72 is circumferentially connected to the inner side of the sealing ring 218. The compression ring 71 is connected to the end of the compression spring 72 away from the sealing ring 218.

[0086] A limiting groove 73 is provided on the inner wall of the accommodating chamber 216, and an abutment piece 74 is rotatably provided in the limiting groove 73. The abutment 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 compression spring 72 are always in a compressed state when the snap-in end 11 is not installed in the accommodating chamber 216.

[0087] When the snap-in end 11 is installed in the accommodating cavity 216, the snap-in end 11 drives the abutment piece 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 the restriction of the abutment piece 74, thereby causing the clamping spring 72 to drive the conductive pin 3 and the conductive needle seat 4 to be further tightened.

[0088] Reference Figure 2 and Figure 3 The reset assembly 24 includes a fixed seat 241, a rotating ring 242, and a reset spring 243. The fixed seat 241 is installed in the end of the female connector housing 21 away from the male connector 1. The rotating ring 242 is a hollow cylinder with two open ends. It is mounted on the female connector housing 21 and is rotatably connected to the fixed seat 241. The inner diameter of the rotating ring 242 is larger than the outer diameter of the female connector housing 21, forming a telescopic chamber 244 between the rotating ring 242 and the female connector housing 21. One end of the sliding sleeve 23 extends into the telescopic chamber 244 and can be extended and retracted within the telescopic chamber 244.

[0089] The return spring 243 is installed in the telescopic chamber 244, with one end connected to the sliding sleeve 23 and the other end 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.

[0090] Reference Figure 3 and Figure 6Furthermore, a locking block 231 is circumferentially provided 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 provided 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 to accommodate or slide the locking block 231. Specifically, when the sliding sleeve 23 is in the locked state, the locking block 231 is located in the locking groove 2421, and when the sliding sleeve 23 is in the unlocked state, the locking block 231 is located in the unlocking groove 2422. When the sliding sleeve 23 switches between the locked and unlocked states, the locking block 231 slides within the connecting channel 2423.

[0091] In this embodiment, adjacent locking grooves 2421 are connected via a connecting channel 2423. The connecting channel 2423 includes an unlocking path 2424 and a locking path 2425. The unlocking path 2424 connects the locking groove 2421 and the unlocking groove 2422 and is inclined. The locking path 2425 connects the unlocking groove 2422 and the adjacent locking groove 2421 and is axially extending along the rotating ring 242.

[0092] Reference Figure 3 、 Figure 6 and Figure 7 To ensure that the sliding sleeve 23 is locked when it is switched to the unlocked state, that is, when the locking block 231 is located in the unlocking slot 2422, a snap-fit strip 2411 is circumferentially provided on the top of the fixed seat 241, corresponding one-to-one with the unlocking slot 2422. Furthermore, an unlocking slot 245 is provided at the bottom of the rotating ring 242, into which the snap-fit strip 2411 is engaged and into which the locking block 231 is locked in the unlocking slot 2422, as well as a sliding slot 246 for the locking block 231 to slide within the connecting channel 2423. The circumferential angle of the sliding slot 246 is greater than that of the unlocking slot 245 to accommodate the movement of the locking block 231 within the connecting channel 2423.

[0093] 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 along the unlocking path 2424 to the unlocking groove 2422. 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.

[0094] 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 is switched from the unlocking state to the locking state under the drive of the return spring 243.

[0095] The above-mentioned method of moving the sliding sleeve 23 by directly driving the rotating ring 242 to rotate 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 or extend, 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 inspect the internal situation of the coaxial connector, and the sliding sleeve 23 can automatically reset after the inspection is completed.

[0096] Reference Figure 3 Furthermore, the elastic force of the return spring 243 can be adjusted to accommodate fatigue of the return spring 243. The fixed seat 241 is circumferentially provided with a limiting adjustment block 2412 that engages with the sliding groove 217. The limiting adjustment block 2412 is provided with an adjustment tooth 2413. The sliding groove 217 is provided with shift slots 219 spaced apart along its length for the adjustment teeth 2413 to selectively engage.

[0097] When the limiting adjustment block 2412 is inserted into the sliding groove 217 , the fixing seat 241 is pressed to cause the adjusting teeth 2413 of the limiting adjustment block 2412 to slide in the sliding groove 217 to select the shift slot 219 , thereby adjusting the elastic force of the return spring 243 .

[0098] 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 inspected after the product production is completed. In this embodiment, the male head 1 is inspected, 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.

[0099] Reference Figure 8 A method for detecting a coaxial connector for cable connection comprises the following steps:

[0100] Step S100: Acquire surface image information of the male connector 1 .

[0101] Surface image information refers to the image information of male connector 1 obtained by the camera when the device places male connector 1 on the test bench. It contains all the characteristic information of the surface of male connector 1. The camera is set on the top of the test bench and can take pictures of the product on the test bench to obtain parameters.

[0102] Step S101: determining reference point features from a preset reference point feature library according to surface image information.

[0103] The reference point feature is a point on the surface of male connector 1 that indicates its current position when it is stationary. This feature identifies the current position of male connector 1, ensuring that it remains in the same position during the next round of testing.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] The clamping device is used to clamp the male connector 1 so as to place the male connector 1 on the test bench.

[0108] The starting position of the test bench is the initial placement position of the male connector 1 when starting the test. In this embodiment, the male connector 1 needs to be placed at the starting position of the test bench to test the male connector 1, and each round of testing starts at the starting position of the test bench.

[0109] The purpose of the reference point feature facing upward is to fix the position of the reference point feature. The reference point feature is located at the same position at the beginning of each round of detection of the male head 1, so that the position state of the male head 1 at the beginning of the test is consistent.

[0110] Step S103: controlling a preset toggling device to toggle the male head 1 according to a preset toggling 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 stops.

[0111] The toggle device is used to toggle the male connector 1 so that the male connector 1 can be rolled. 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.

[0112] The first overhead image refers to an image of the male head 1 obtained by photographing the male head 1 from 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.

[0113] 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.

[0114] 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 the second round of repeated testing.

[0115] In this embodiment, after obtaining the first overhead image, the male head 1 is reset 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 a second overhead 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.

[0116] In order to avoid the situation where the male plug 1 pushed out by the same driving force may remain in the same position regardless of whether it is eccentric, the driving force is changed in the second repeated test. The preset increase is the amount of change in the driving force set by the technician and is not detailed here.

[0117] Step S1041: Based on the inconsistency between the first overhead view image and the second overhead view image, the detection is completed and a qualified prompt is output.

[0118] If male connector 1 is off-center, its center of gravity is not on the central axis. At this point, regardless of when male connector 1 is stationary, its center of gravity will ultimately be at its lowest point. Therefore, male connector 1 will remain stationary on the test bench in the same position, and the reference point feature will remain in the same position during each test. If male connector 1 is a qualified product, meaning its center of gravity is on the central axis, moving male connector 1 with different forces will cause it to remain stationary in different positions.

[0119] In a detection environment where the starting position and the reference point feature position of the male head 1 are the same and the toggling 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.

[0120] 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 connector 1 is inspected using a preset defective product cause determination method, and a defective product prompt is output.

[0121] In an inspection environment where the starting point and reference point feature positions of male contact 1 are identical, but the force of the pull is different, if the first and second top-view images are inconsistent, it indicates that male contact 1 is eccentric and is therefore classified as defective. The system then retests the male contact 1 to determine the cause of the defect and correct it. The method for determining the cause of defective products is not detailed here and will be described in detail in subsequent examples.

[0122] The method for determining the cause of defective products includes the following steps:

[0123] Step S200: Acquire end face image information of the shell of the male connector 1.

[0124] The end face image information refers to an image of the male connector 1 housing obtained when the camera is photographed perpendicularly to the end face of the male connector 1 housing. The end face image information is an orthographic projection view.

[0125] Step S201: Identify end face image information and analyze to obtain end face contour features.

[0126] 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.

[0127] The end face profile features can be identified and analyzed from the end face image information.

[0128] Step S202: determining the product end face radius from a preset product database according to the preset male connector 1 model information.

[0129] The male connector model information is the standard model of the male connector 1 to be tested. All parameter information of the male connector 1 can be queried based on the male connector model information, which will not be described in detail here.

[0130] The product end face radius refers to the contour radius of the end face of a specific model of male connector 1.

[0131] The product database is a database that includes parameter information of all coaxial connectors, including the male connector model information and the product end face radius of male connector 1. The product end face radius can be matched from the product database based on the male connector model information.

[0132] Step S203: Generate a circular contour feature according to the end face radius of the product.

[0133] The circular profile feature is a circular feature model used for profile shape comparison. After determining the end face radius of the product, a circular profile feature for reference comparison can be obtained based on the end face radius of the product.

[0134] 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 based on the end face contour feature.

[0135] The end face contour features are overlapped and compared with the circular contour features. If the two are inconsistent, it means that the end face of the male connector 1 to be detected is not circular, and it has a certain deformation and eccentricity. At this time, the system will issue a prompt that the contour of the male connector 1 is abnormal.

[0136] 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 the circle needs to be corrected to a distance from the center of the circle equal to the end face radius of the product.

[0137] Step S205: determining a diameter adjustment value according to the end face radius and the shortest diameter of the product, and matching a preset expanding force of the rounding device according to the diameter adjustment value.

[0138] 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.

[0139] The rounding device is used to expand the contour of the eccentric male connector 1 end face, circumferentially expanding it to an overall circular shape. The expansion force is the force applied by the rounding device to the male connector 1 end face; the greater the applied force, the greater the expansion distance. The expansion force is proportional to the diameter adjustment value; the larger the diameter adjustment value, the greater the expansion force.

[0140] When the point with the shortest diameter on the outline of 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 outline of male connector 1 can be adaptively deformed and eventually become a circle.

[0141] Step S206: Controlling the rounding device to open the shell of the male connector 1 according to the opening force to correct it into a round shape.

[0142] After the expansion force is determined, the system controls the rounding device to extend into the male head 1 and expand the end face of the male head 1, so that the end face of the male head 1 is finally circular, and the radius of the end face contour is the end face radius of the product.

[0143] In addition to the eccentricity caused by the deformation of the shell, the defective male connector 1 may also be caused by abnormalities in the conductive pins 3 inside the male connector 1. The method for determining the cause of the defective product also includes the following steps:

[0144] 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.

[0145] The end face contour features are overlapped and compared with the circular contour features. 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. It may be that the conductive pin 3 inside the male connector 1 is tilted, causing the male connector 1 to be eccentric.

[0146] 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.

[0147] 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.

[0148] By identifying and matching the end face image information with the pin feature library, the conductive pin features and conductive pin positions can be determined.

[0149] Step S301: determining an image shape type according to the end face image information and the conductive pin features, where the image shape types include dot shape and line shape.

[0150] Because the end-face image information is an orthographic projection, if the conductive pin feature is normal, it will appear as a dot in the end-face image information. If the conductive pin feature is tilted, it will appear as a line in the end-face image information. Based on the end-face image information and the conductive pin feature, the image shape type of the conductive pin feature can be determined.

[0151] Step S3011: Complete detection based on point shape.

[0152] 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 cause of 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.

[0153] Step S3012: Based on the line shape, define the pin as tilted, output the pin tilt prompt, and obtain the overall pin image of the conductive pin feature.

[0154] If the image shape is linear, it indicates that the conductive pin 3 of the male connector 1 is tilted. The system needs to clarify the position of the conductive pin 3. At this time, the camera angle is adjusted to obtain a full-length image of the pin with the conductive pin's characteristics. The full-length image of the pin is not an orthographic projection view. It includes the entire image of the conductive pin 3, which includes the pin portion and the mounting portion. Both the pin portion and the mounting portion are included in the full-length image.

[0155] Step S302: determining the pin portion feature and the mounting portion feature of the conductive pin feature based on the overall pin image, and analyzing whether the pin portion feature and the mounting portion feature are coaxial based on the overall pin image recognition.

[0156] After obtaining the overall image of the pin, the image can be identified to determine the pin portion features and the mounting portion features of the conductive pin 3. The system then determines whether the axes of the two are coaxial through image recognition.

[0157] 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.

[0158] 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 transparent material, so the conductive pin 3 can be identified as a whole in the overall pin image.

[0159] By analyzing whether the two axes are coaxial, we can distinguish the above two situations and solve them specifically.

[0160] Step S3021: Based on the different axes, determine the tilt 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 tilt angle.

[0161] 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.

[0162] The straightening device is used to straighten the conductive pins 3. The straightening device includes a clamping jaw, which can clamp the conductive pins 3 at the conductive pin position and tilt them at a certain angle.

[0163] 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 .

[0164] After determining the tilt angle, the system controls the straightening device to extend to the conductive pin position to straighten the conductive pin 3.

[0165] Step S3022: Based on the coaxiality, a preset pressing device is controlled with a preset pressing force to squeeze the preset insulating pads on both sides of the mounting portion feature.

[0166] 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 tilt as a whole. At this time, straightening by a straightening device is only a temporary solution and the insulating pad needs to be adjusted.

[0167] The pressing device is used to press the insulating pad. The pressing device has two pressing parts. Each pressing part can extend from both ends of the male connector 1 and press the insulating pad.

[0168] The pressing force is the force applied by the pressing device to the insulating pad when pressed by the technician. The applied force is not easy to damage the conductive pin 3, and will not be described in detail here.

[0169] After the insulating pads on both sides of the mounting feature are squeezed by the pressing device, the conductive pin 3 can be reset to the axial position. At this time, the conductive pin 3 needs to be further fixed.

[0170] Step S303: Control the puncture needle heated to a preset melting temperature to penetrate the insulation pad at a preset penetration depth to heat and fuse the insulation pads on both sides of the mounting portion feature.

[0171] The melting temperature is a temperature at which the insulating pad can be melted. The puncture needle is used to pierce the insulating pads on both sides of the mounting portion and use the high temperature it carries to fuse the two insulating pads at the piercing position and fix them.

[0172] The penetration depth is the depth set by the 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. It will not be elaborated here.

[0173] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
