Description

Technical Field

[0001] This invention relates to the field of measuring device technology, and in particular to a laser measuring device for the contact gap of an electrical connector. Background Technology

[0002] Electrical connectors are devices used to connect, disconnect, or transfer electrical signals, and are widely used in electronics, communication equipment, and the automotive industry. Their core function is to establish an electrical connection and transmit current or signals. They typically consist of a plug (female) and a socket (male), and circuit closure and disconnection are achieved through contact points.

[0003] To ensure that electrical connectors meet design requirements and safety standards in terms of electrical performance, mechanical reliability, and environmental adaptability, it is necessary to measure the contact gap of the electrical connectors. A reasonable contact gap can effectively reduce contact resistance and the risk of electrical breakdown. Commonly used contact gap measurements include mechanical measurement with calipers and laser measurement.

[0004] Laser measurement technology, with its non-contact, high-precision, and fast-response characteristics, has become the preferred solution for contact gap measurement. However, when using laser measurement to measure the contact gap of electrical connectors, oil stains and oxide layers on the surface of the metal contacts can cause changes in the refraction angle of the laser, thereby increasing the detection error of the contact gap. Furthermore, some contact surfaces are arc-shaped, which further increases the uncertainty of the laser reflection angle, thus affecting the detection accuracy. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 9 The present invention provides a technical solution:

[0034] A laser measuring device for the contact gap of an electrical connector includes a base 11, a drive seat 12, an electrical connector 14, and a laser detector 51. An adjusting rod 22 is threadedly connected to the upper outer surface of the drive seat 12. A movable part is provided on the upper side of the adjusting rod 22, and a guide seat 26 is movably connected to the adjusting rod 22 through the movable part. A support plate 21 is fixedly connected to the lower outer surface of the laser detector 51. An offset component is provided between the guide seat 26 and the support plate 21. The offset component includes a pressing groove 27 that penetrates through the outer surface of the support plate 21. The guide seat 26 extends through the pressing groove 27 to the lower side of the support plate 21. A moving groove 32 is embedded in the inner side of the guide seat 26. A pressing block 28 is slidably connected to the inner side of the moving groove 32. The pressing block 28 extends through to the outer side of the guide seat 26 and slides in contact with the inner wall of the pressing groove 27. The outer surface of the support plate 21 is arc-shaped.

[0035] The movable part includes a movable rod 24 fixedly connected to the upper end of the adjusting rod 22. A movable sleeve 23 is rotatably connected to the outer surface of the movable rod 24. A locking rod 25 is threadedly connected to the outer surface of the movable sleeve 23. The locking rod 25 passes through the interior of the movable sleeve 23 and contacts the outer surface of the movable rod 24. The upper outer surface of the movable sleeve 23 is fixedly connected to the lower end of the guide seat 26. A photosensitive plate 13 is fixedly connected to the upper outer surface of the drive seat 12. The photosensitive plate 13 is symmetrically distributed with the laser detector 51.

[0036] The outer surface of the extrusion block 28 is inclined. There are two sets of extrusion blocks 28, which are symmetrically distributed. A top block 29 is slidably connected to the outer surface of the extrusion block 28. The outer surface of the top block 29 is conical. An extrusion rod 30 is fixedly connected to the upper outer surface of the top block 29. The upper end of the extrusion rod 30 extends through to the upper side of the guide seat 26 and is threadedly connected to the guide seat 26. A locking sleeve 31 is threadedly connected to the outer surface of the extrusion rod 30.

[0037] By adopting the above technical solution, when measuring the contact gap of the electrical connector 14, the position of the electrical connector 14 is first stabilized, so that the electrical connector 14 is at the center of the drive seat 12. In order to keep the angle between the laser detector 51 and the electrical connector 14 within an appropriate range, an offset component is set. The adjusting rod 22 is threadedly connected to the drive seat 12. By rotating the adjusting rod 22, the height of the laser detector 51 can be adjusted, so that the laser detector 51 corresponds to the contact area of ​​the electrical connector 14. The adjusting rod 22 is used to adjust the height of the movable rod 2. 4. Fixed support: The upper side of the movable rod 24 is spherical. The movable sleeve 23 is rotatably connected to the movable rod 24, allowing the movable sleeve 23 to rotate at different angles outside the movable rod 24. When the movable sleeve 23 rotates to an appropriate angle, the operator turns the locking rod 25 to make the locking rod 25 contact the outer surface of the movable rod 24. Under the squeezing force of the locking rod 25, the movable rod 24 and the movable sleeve 23 can be kept stable. The support plate 21 is used to support the laser detector 51. The outer surface of the support plate 21 is arc-shaped, which allows the laser detector 51 to be rotated to different positions. To adjust the angle of the laser detector 51, the operator first loosens the locking sleeve 31 and rotates the extrusion rod 30 clockwise. This causes the top block 29 to move upwards via the adjusting rod 22, disengaging it from the extrusion block 28. Then, the angle between the laser detector 51 and the support plate 21 is adjusted. The support plate 21 slides against the guide seat 26 via the extrusion groove 27. After the laser detector 51 is adjusted to the appropriate angle, the operator rotates the extrusion rod 30 counterclockwise. During this movement, the extrusion rod 30 causes the top block 29 to move downwards. During the process, the extrusion block 28 is extruded. At this time, the extrusion block 28 slides outward inside the moving groove 32. Then, the outer surface of the extrusion block 28 contacts the inner wall of the extrusion groove 27. Through the extrusion block 28 and the extrusion groove 27, the position of the support plate 21 and the laser detector 51 can be locked and fixed, so that the laser detector 51 can remain stable during operation. This can reduce the probability of optical feedback deviation caused by oil and oxide layer on the contact surface to a certain extent, thereby further improving the detection accuracy of the contact gap of the electrical connector 14.

[0038] Specifically, such as Figure 4 , Figure 7 and Figure 8 As shown, a drive assembly is provided on the outer side of the base 11. The drive assembly includes a slot 19 embedded in the lower outer surface of the base 11. A motor 20 is fixedly connected to the upper side of the inner surface of the slot 19. A drive shaft 33 is fixedly connected to the upper end of the output shaft of the motor 20. The drive shaft 33 passes through to the upper side of the base 11 and is rotatably connected to the base 11. A gear 34 is fixedly connected to the outer surface of the drive shaft 33.

[0039] The drive seat 12 is located on the upper side of the base 11 and rotates in contact with the base 11. The drive seat 12 is annular. The inner surface of the drive seat 12 is fixedly connected with teeth 16. The gear 34 meshes with the teeth 16 for transmission. The upper outer surface of the base 11 is embedded with a limiting groove 43. The inner side of the limiting groove 43 is rotatably connected to a limiting block 44. The upper outer surface of the limiting block 44 is fixedly connected to the drive seat 12.

[0040] Both the limiting block 44 and the limiting groove 43 are annular. A ball bearing 45 is rotatably connected to the lower outer surface of the limiting block 44. The ball bearing 45 is in rotatable contact with the inner surface of the limiting groove 43. The ball bearing 45 consists of several groups and is distributed in a ring array. A cover 17 is fixedly connected to the upper outer surface of the base 11. A movable cover 18 is hinged to the middle of the upper outer surface of the cover 17. During operation, the movable cover 18 covers the upper side of the cover 17. The cover 17 and the movable cover 18 can seal the drive seat 12, thereby reducing the influence of external light source on the detection to a certain extent. The movable cover 18 can be flipped at a certain angle by hinge with the chassis, thereby enabling quick loading and unloading of the electrical connector 14.

[0041] By adopting the above technical solution, in order to further improve the detection accuracy, a drive assembly is set up. Then, the motor 20 is started and running. The output shaft of the motor 20 drives the drive shaft 33 to rotate. The base 11 is fixedly installed on the motor 20 through the slot 19. During the rotation of the drive shaft 33, the gear 34 will rotate synchronously. The gear 34 is connected by meshing with the teeth 16. As the gear 34 rotates, it drives the drive seat 12 to rotate. The limiting block 44, together with the limiting groove 43, can limit the drive seat 12, so that the drive seat 12 can rotate around the electrical connector 14 as the center. The ball 45 on the lower side of the limiting block 44 can reduce the speed to a certain extent. The reduced moving resistance of the drive seat 12 makes its movement smoother. During rotation, the drive seat 12 drives the laser detector 51 and the photosensitive plate 13 to make circular motion. The laser detector 51 emits laser light towards the electrical connector 14 in different directions. The laser detector 51 in this application adopts the disclosed prior art, so its specific working structure and principle will not be described in detail here. The photosensitive plate 13 captures the reflection contour, and the gap width of the electrical connector 14 is calculated by combining the triangulation principle. By setting the drive component, the electrical connector 14 can be measured in different directions, which can further reduce the detection error and help improve the measurement accuracy of the contact gap.

[0042] Specifically, such as Figure 4 , Figure 5 and Figure 9As shown, a clamping assembly is provided on the upper side of the base 11. The clamping assembly includes a magnetic plate 42 fixedly connected to the upper outer surface of the base 11. A support rod 41 is magnetically connected to the upper outer surface of the magnetic plate 42. A support plate 46 is fixedly connected to the upper outer surface of the support rod 41. A clamping groove 47 is embedded in the upper outer surface of the support plate 46. A clamping block 49 is slidably connected to the inner side of the clamping groove 47.

[0043] An elastic plate 48 is fixedly connected to the outer surface of the clamping block 49. The outer surface of the elastic plate 48 is arc-shaped. There are two sets of clamping blocks 49 and elastic plates 48, which are symmetrically distributed. An elastic band 50 is fixedly connected between the two sets of clamping blocks 49. The elastic band 50 is used to clamp and fix the electrical connector 14. The lower end of the electrical connector 14 is in contact with the upper surface of the support plate 46.

[0044] By adopting the above technical solution, the magnetic plate 42 on the surface of the base 11 is used to magnetically fix the support rod 41. According to the size of the electrical connector 14, different lengths of support rods 41 are selected so that the position of the electrical connection can always be in the appropriate position. In order to keep the electrical connector 14 stable during the testing process, a clamping assembly is set up. During operation, the lower side of the electrical connector 14 is placed between two sets of elastic plates 48. The clamping groove 47 on the surface of the support plate 46 is used to slide and support the clamping plate 40. The clamping block 49 can slide and guide the elastic plate 48. Under the elastic force of the elastic band 50, the elastic plate 48 can clamp and fix the lower end of the electrical connector 14, so that the position of the electrical connector 14 can always be kept stable. By setting up the clamping assembly, not only can the electrical connector 14 be clamped and fixed quickly, but it can also reduce the obstruction of light by other components, thereby further reducing the testing error.

[0045] Specifically, such as Figure 4 and Figure 7 As shown, a limiting component is provided on the outer side of the support rod 41. The limiting component includes a fixing tube 15 fixedly connected to the upper outer surface of the base 11. A clamping plate 40 is fixedly connected to the inner surface of the fixing tube 15. The clamping plates 40 are arranged in several groups in a ring array. The lower end of the clamping plate 40 is in contact with the outer surface of the support rod 41. The clamping plate 40 is made of elastic material. A top plate 38 is fixedly connected to the lower outer surface of the support plate 46. The lower end of the top plate 38 is in contact with the outer surface of the clamping plate 40.

[0046] The inner surface of the fixed tube 15 is embedded with a guide groove 35, which is located between two adjacent sets of clamping plates 40. A guide block 36 is slidably connected to the inner side of the guide groove 35. A pull rod 37 is fixedly connected to the outer surface of the guide block 36. The pull rod 37 is annular and contacts the upper outer surface of the clamping plate 40. An extrusion plate 39 is fixedly connected between the lower outer surface of the clamping plate 40 and the fixed tube 15. The extrusion plate 39 has a U-shaped structure and is made of elastic material.

[0047] By adopting the above technical solution, in order to further improve the clamping stability of the electrical connector 14, a limiting component is set. The fixing tube 15 is used to support the clamping plate 40. Under the elastic force of the pressing plate 39, the clamping plate 40 will flip upward. At this time, the lower end of the clamping plate 40 will contact the outer surface of the support rod 41. The circularly distributed clamping plates 40 are used to abut and limit the support rod 41, thereby keeping the position of the support rod 41 stable. This helps to reduce the vibration caused to the electrical connector 14 when the drive component is working, and thus can effectively reduce the impact of the electrical connector 14 shaking. The accuracy of contact gap measurement is affected, thus ensuring the detection accuracy of contact gap. The top plate 38 on the lower side of the support plate 46 can prevent the clamping plate 40 from over-twisting. When replacing the support rod 41, the operator slides the guide block 36 downward along the inside of the guide groove 35. As the guide block 36 moves downward, it will drive the pull rod 37 to move synchronously. The guide block 36 squeezes the surface of the clamping plate 40, causing the clamping plate 40 to expand outward from the gathered state, thereby causing the clamping plate 40 to disengage from the outer surface of the support plate 21, so that the support rod 41 can be quickly removed and replaced.

[0048] Working principle: When the laser measuring equipment is working, the lower side of the electrical connector 14 is placed between two sets of elastic plates 48. Under the elastic force of the elastic band 50, the elastic plates 48 can clamp and fix the lower end of the electrical connector 14, thus keeping the position of the electrical connector 14 stable. The clamping plate 40 will flip upward under the elastic force of the pressing plate 39. At this time, the lower end of the clamping plate 40 will contact the outer surface of the support rod 41. The circularly distributed clamping plates 40 are used to resist and limit the support rod 41, thus keeping the position of the support rod 41 stable. The gear 34 is connected to the gear tooth 16 through meshing transmission. As the gear 34 rotates, it will drive the drive seat 12 to rotate. During the rotation of the drive seat 12, it will drive the laser detector 51 and the photosensitive plate 13 to perform circumferential motion. The laser detector 51 will emit laser light towards the electrical connector 14 in different directions. The photosensitive plate 13 captures the reflected contour and combines it with the triangulation principle. The gap width of the electrical connector 14 is calculated. By setting the drive component, the electrical connector 14 can be measured in different directions. The movable sleeve 23 is rotatably connected to the movable rod 24, so that the movable sleeve 23 can rotate at different angles outside the movable rod 24. The support plate 21 is used to support the laser detector 51. The outer surface of the support plate 21 is arc-shaped, which allows the laser detector 51 to be flipped to different angles. During the movement, the pressing rod 30 will drive the top block 29 to move downward. During the downward movement of the top block 29, it will press the pressing block 28. At this time, the pressing block 28 will slide outward inside the moving groove 32. Then the outer surface of the pressing block 28 will contact the inner wall of the pressing groove 27. Through the pressing block 28 and the pressing groove 27, the position of the support plate 21 and the laser detector 51 can be locked and fixed, so that the laser detector 51 can remain stable during operation.
