[0028] The initial state of the auxiliary rod assembly is that the auxiliary rod assembly is located in the corresponding pressing slider 5. When the limiting rod 752 presses the auxiliary rod 8, the other side of the auxiliary rod 8 is inserted into the clamping cavity of the auxiliary measuring plate 25. At this time, the second spring 81 is in a deformed state, and when the limiting rod 752 no longer presses the auxiliary rod 8, the auxiliary rod 8 is reset under the action of the second spring 81, and the auxiliary rod assembly is located in its pressing slider 5.

[0033] The limiting structure 7 includes a turntable 72, one side of which is connected to a second rotating shaft driven by a first servo motor 71. A T-shaped fixing member 76 is fixedly installed below the middle of the other end of the turntable 72. A movable connecting member 73 is provided at the other end of the turntable 72 through the T-shaped fixing member 76. A second auxiliary chute is vertically penetrated through the movable connecting member 73, and the width of the second auxiliary chute is consistent with the outer diameter of the T-shaped fixing member 76. Furthermore, movable rods 74 are fixedly mounted at the middle of both ends of the movable connecting member 73. A plunger assembly 75 is slidably mounted on the end of the movable rod 74 away from the rotary disk 72. A third auxiliary slot is defined within the movable rod 74 at the plunger assembly 75. The plunger assembly 75 includes a limiting slider 751. A limiting plunger 752 is inserted into the limiting slider 751. The limiting plunger 752 is parallel to the pressing slider 5. The cross-sectional area of ​​the limiting slider 751 is larger than that of the limiting plunger 752. A third through-hole is defined within the limiting slider 751 at the limiting plunger 752.

[0035] Furthermore, when the hand grip plate is located at one end of the adjacent limiting auxiliary slot, the first spring 51 is in a deformed state, and at this time, the auxiliary rod assembly is aligned with its clamping cavity.

[0036] At the same time, it is worth noting that the second spring 81, the third spring 64, the fourth spring 94, and the fifth spring 903 are all equipped with damping components, and the damping components are not drawn in the figure. The model of the first laser rangefinder 41 is KJT-FG30, and the model of the second laser ranging module 42 is VL53L0X.

[0037] It is worth noting that the specific structures and working principles of the first laser rangefinder 41, the second laser ranging module 42, the first electric telescopic rod 3, the second servo motor and the hydraulic rod assembly, and the first servo motor 71 are all existing technologies currently disclosed on the market, and do not belong to the main technical problems to be solved by the present invention, so they are not elaborated in detail.

[0038] At the same time, it is worth mentioning that when the first servo motor 71 rotates toward the side of the fixed measuring rod 23, it is forward rotation; when the first servo motor 71 rotates away from the side of the fixed measuring rod 23, it is reverse rotation; when the second servo motor rotates toward the side of the second limit component 92, it is forward rotation; when the second servo motor rotates toward the side of the first limit component 91, it is reverse rotation.

[0039] When the first servo motor 71 is in the initial position, its T-shaped fixing part 76 is on the same vertical line as the center of the turntable 72, and the T-shaped fixing part 76 is located below the second rotating shaft. The limiting rod 752 of its limiting structure 7 limits the adjacent pressing slider 5, and when the second servo motor is in the initial position, the movable rocker 901 of its first limiting component 91 and the second limiting component 92 are both in an inclined state.

[0040] At the same time, the initial state of the elastic block 61 is that the elastic block 61 is partially located outside the auxiliary measuring piece 26, and its spring is in a deformed state, and its limiting protrusion is located in the middle of the heart-shaped guide groove 621 and close to the side of the elastic block 61.

[0041] In the present invention, when it is necessary to measure the pin of the male connector of the RF connector to be tested, the male connector to be measured is placed under the measuring component 2, and by controlling the hydraulic rod assembly, the fixed measuring rod 23 of the measuring component 2 is initially located inside the male connector and above its pin. Then, the measuring component 2 drives its movable block 22 to move through the first electric telescopic rod 3, so that the fixed measuring rod 23 and the movable measuring rod 24 are respectively located on both sides of the pin.

[0042] Continue to control the hydraulic rod assembly to move the fixed measuring rod 23 and the movable measuring rod 24 toward the male head until the bottom of the fixed measuring rod 23 and the bottom of the movable measuring rod 24 are in contact with the bottom of the male head, and drive the movable block 22 to move through the first electric telescopic rod 3 until the fixed measuring rod 23 is in contact with the outer wall of the pin, and measure the distance from the transmitting end to the corresponding auxiliary measuring plate 25 through the first laser rangefinder 41, where the height of the male head pin = the reading of the first laser rangefinder 41 - the thickness of the auxiliary measuring plate 25.

[0043] When it is necessary to measure the outer diameter of the male pin, the first servo motor 71 is controlled to rotate forward, and the limiting rod 752 away from the side of the fixed measuring rod 23 moves along the transition guide groove into the first guide groove, and one end of the limiting rod 752 is moved away from the pressing slider 5 under the action of the second spring 81 and loses the limit on the pressing slider 5.

[0044] At the same time, the second servo motor is controlled to reverse so that its movable pressure rod 93 rotates, and one end of the movable pressure rod 93 presses the connecting slide 95 of its first limiting component 91. At this time, its fourth spring 94 is in a deformed state, and the movable seesaw 901 of the second limiting component 92 rotates to a certain extent under the action of the fifth spring 903. The movable seesaw 901 is in a tilted state, and at this time the other end of its movable pressure rod 93 is away from its second limiting component 92. The connecting slide 95 of the second limiting component 92 is in a free state when the fourth spring 94 is in a free state, so that the connecting slide 95 moves toward the movable pressure rod 93 and moves its auxiliary pull rope 904, driving the movable seesaw 901 to rotate, and making the movable seesaw 901 located in the movable cavity.

[0045] At the same time, the limiting rod 752 of the rod assembly 75 on the side of the limiting structure 7 away from the fixed measuring rod 23 is located in the first guide groove, and loses the limiting effect on the pressing slider 5 on the side away from the fixed measuring rod 23. At the same time, the pressing slider 5 on the side away from the fixed measuring rod 23 moves toward and presses the movable measuring rod 24 under the action of the first spring 51.

[0046] At the same time, the limiting rod 752 of the rod assembly 75 on the side of the limiting structure 7 away from the fixed measuring rod 23 is located in the adjacent first guide groove, and loses the limiting effect on the pressing slider 5 on the side close to the fixed measuring rod 23. At the same time, the pressing slider 5 on the side close to the fixed measuring rod 23 moves toward and presses the movable measuring rod 24 under the action of the first spring 51 until the movable measuring rod 24 is basically in contact with the outer wall of its male pin.

[0047] At the same time, when the pressing slider 5 moves, the movable seesaw 901 of its first limiting assembly 91 does not hinder the pressing slider 5 from moving toward the movable measuring rod 24. Through the setting of the movable seesaw 901, when the pressing slider 5 retracts under the action of the first spring 51, its adjacent movable seesaw 901 limits and resists it, thereby preventing the pressing slider 5 from retracting under the action of the first spring 51.

[0048] At the same time, the pressing slider 5 presses its elastic block 61, and the elastic block 61 moves into the limiting slot, and its limiting protrusion slides along the heart-shaped guide slot 621. When the pressing slider 5 retracts under the action of the first spring 51, the pressing slider 5 loses the pressure on the elastic block 61, and the pressing slider 5 moves toward the outside of the auxiliary measuring piece 26 under the action of the third spring 64. At this time, its limiting protrusion slides along the heart-shaped guide slot 621 and moves to the side away from the elastic block 61. When its limiting protrusion slides in the heart-shaped guide slot 621, the positioning rod rotates synchronously in the movable cavity, and is pressed by the elastic block 61 and the pressing slider 5, so that its movable measuring rod 24 is further fitted to the outer wall of the male pin, and the distance from the emitting end of the second laser ranging module 42 to the auxiliary measuring piece 26 is measured by the second laser ranging module 42, where the measured value of the outer diameter of the male pin = the reading of the second laser ranging module 42 - the length of the second laser ranging module 42.

[0049] When it is necessary to measure the depth of the female connector's socket, the female connector to be measured is placed under the measuring assembly 2, and by controlling the hydraulic cylinder assembly, its fixed measuring rod 23 is driven to be initially located inside the female connector and above its socket. Then, the measuring assembly 2 drives its movable block 22 to move through the first electric telescopic rod 3, so that the fixed measuring rod 23 and the movable measuring rod 24 are respectively located inside the socket.

[0050] Then, continue to control the hydraulic rod assembly to move the fixed measuring rod 23 and the movable measuring rod 24 into the female head until the bottom of the fixed measuring rod 23 and the bottom of the movable measuring rod 24 are in contact with the bottom of the female head, and drive the movable block 22 to move through the first electric telescopic rod 3 until the fixed measuring rod 23 is in contact with the inner wall of one side of the socket. At this time, the bottom of the auxiliary measuring plate 25 of its measuring assembly 2 is in contact with the top of the female head pin, and the distance from the transmitting end to the auxiliary measuring plate 25 is measured by the first laser rangefinder 41, where the depth of the female head socket = the reading of the first laser rangefinder 41 - the thickness of the auxiliary measuring plate 25.

[0051] When it is necessary to measure the inner diameter of the female plug socket, the first servo motor 71 is controlled to reverse, and the limiting rod 752 close to the side of the fixed measuring rod 23 moves along the transition guide groove into the first guide groove, and one end of the limiting rod 752 is moved away from the pressing slider 5 under the action of the second spring 81 and loses the limit on the pressing slider 5.

[0052] At the same time, the second servo motor is controlled to rotate forward, so that its movable pressure rod 93 rotates, and one end of the movable pressure rod 93 presses the connecting slide 95 of its second limiting component 92. At this time, its fourth spring 94 is in a deformed state, and the movable seesaw 901 of the second limiting component 92 rotates a certain amount under the action of the fifth spring 903. The movable seesaw 901 is in an inclined state, and at this time the other end of its movable pressure rod 93 is away from its first limiting component 91. The connecting slide 95 of the first limiting component 91 is in a free state in the fourth spring 94, so that the connecting slide 95 moves toward the movable pressure rod 93, and moves its auxiliary pull rope 904, driving the movable seesaw 901 to rotate, and making the movable seesaw 901 located in the movable cavity.

[0053] At the same time, at this time, the limiting rod 752 of the rod assembly 75 of the limiting structure 7 close to the side of the fixed measuring rod 23 is located in the adjacent first guide groove, and loses the limiting effect on the pressing slider 5 close to the side of the fixed measuring rod 23. At the same time, the pressing slider 5 close to the side of the fixed measuring rod 23 moves toward the movable measuring rod 24 and presses under the action of the first spring 51 until the movable measuring rod 24 basically fits the inner wall of its female plug hole.

[0054] At the same time, when the pressing slider 5 moves, the movable seesaw 901 of its second limiting assembly 92 does not hinder the pressing slider 5 from moving toward the movable measuring rod 24. Through the setting of the movable seesaw 901, when the pressing slider 5 retracts under the action of the first spring 51, its adjacent movable seesaw 901 limits and resists it, thereby preventing the pressing slider 5 from retracting under the action of the first spring 51.

[0055] At the same time, the pressing slider 5 presses its elastic block 61, and the elastic block 61 moves into the limiting slot, and its limiting protrusion slides along the heart-shaped guide slot 621. When the pressing slider 5 retracts under the action of the first spring 51, the pressing slider 5 loses the pressure on the elastic block 61, and the pressing slider 5 moves toward the outside of the auxiliary measuring part 26 under the action of the third spring 64. At this time, its limiting protrusion slides along the heart-shaped guide slot 621 and moves to the side away from the elastic block 61. When its limiting protrusion slides in the heart-shaped guide slot 621, the positioning rod rotates synchronously in the movable cavity, and is pressed by the elastic block 61 and the pressing slider 5, so that the movable measuring rod 24 is further fitted to the inner wall of the female plug hole, and the distance from the emitting end of the second laser ranging module 42 to the auxiliary measuring part 26 is measured by the second laser ranging module 42, and one side of the second laser ranging module 42 is fitted with the outer wall of the adjacent fixed measuring rod 23.

[0056] The measured value of the inner diameter of the female plug hole = the reading of the second laser ranging module 42 + (the diameter of the fixed measuring rod 23 + the diameter of the auxiliary measuring piece 26 + the length of the second laser ranging module 42).

[0057] Among them, when the height of the male pin is consistent with the depth of the female jack, the height of the male pin matches the depth of the female jack, and when the measured value of the inner diameter of the female jack is consistent with the measured value of the outer diameter of the male pin, the male and female connectors can be plugged in smoothly.

[0058] When it is necessary to measure a new male or female head, first hold the hand-grip plate that presses the slider 5 and move it until the hand-grip plate is located at one end of the adjacent limit auxiliary groove. The first spring 51 is in a deformed state, and at this time the auxiliary rod assembly is aligned with its clamping cavity, and the first servo motor 71 is in the initial position.

[0059] In the present invention, the test unit 11 of the test device body 1 can be used to simultaneously measure the pin height and outer diameter of the male connector of the RF connector, or the depth and inner diameter of the female connector's jack can be simultaneously measured, thereby improving measurement efficiency. Through the cooperation of the hydraulic rod assembly, the first electric telescopic rod 3, and the auxiliary pressing assembly 6, the measuring assembly 2 can accurately contact and fit with the measured part, thereby ensuring the accuracy of the measurement data.

[0060] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
