[0054] At the same time, after the self-floating unlocking of the male mounting seat 2, the parameters of the automatic docking equipment used in the actual production process can be guided according to the test results, and the recommended floating value can be given.

[0055] Regarding the female mounting seat 1, in one embodiment of the present application, as Figure 1 and Figure 2 As shown, preferably, the female mounting seat 1 includes a first mounting plate 11, a second mounting plate 12 and a third mounting plate 13, the first mounting plate 11 is slidably disposed on the bottom plate along the Y direction through a slide plate 16, the second mounting plate 12 and the third mounting plate 13 are both disposed on the side of the first mounting plate 11 facing the male mounting seat 2, and the second mounting plate 12 is located between the third mounting plates 13.

[0056] A first connecting hole is provided on the first mounting plate 11, a second connecting hole is provided on the second mounting plate 12, and a third connecting hole is provided on the third mounting plate 13, wherein the second connecting hole is a threaded hole for passing the first screw, and the first connecting hole and the third connecting hole are arranged opposite to the second connecting hole for the first screw to pass through; nuts are provided at both ends of the first screw, and the two nuts can be both screwed on the first screw, or one is fixed to one end of the first screw and the other is screwed on the first screw; the nut at one end of the first screw is tightly abutted against the first mounting plate 11 through a gasket, and the nut at the other end of the first screw is tightly abutted against the third mounting plate 13 through another gasket, thereby fastening the first mounting plate 11, the second mounting plate 12 and the third mounting plate 13 together.

[0057] The apertures of the first connecting hole and the third connecting hole are both larger than the diameter of the first screw, so that when the nut on the first screw is not tightened, the relative positions of the first mounting plate 11, the second mounting plate 12 and the third mounting plate 13 can be adjusted along the X-direction and the Z-direction to adjust the alignment deviation of the female head 10 along the X-direction and the Z-direction.

[0058] In this embodiment, preferably, the first mounting plate 11, the second mounting plate 12 and the third mounting plate 13 are all square plates, the first mounting plate 11 is provided with a first connecting hole at the four top corners, the second mounting plate 12 is provided with a second connecting hole at the four top corners, the third mounting plate 13 is provided with a third connecting hole at the four top corners, and the four first connecting holes, the four second connecting holes and the four third connecting holes are relatively arranged one by one.

[0059] In this embodiment, preferably, Figure 2 As shown, the female head mounting seat 1 also includes a first floating rod 14 and a second floating rod 15. The first mounting plate 11 and the second mounting plate 12 are both formed with an arc-shaped first limiting groove, the openings of the two first limiting grooves are opposite, the first floating rod 14 is adaptively accommodated between the two first limiting grooves, the axis of the first floating rod 14 is along the Z direction, and the axis of the first floating rod 14 is perpendicular to the axis of the female head 10. The second mounting plate 12 and the third mounting plate 13 are both formed with an arc-shaped second limiting groove, the openings of the two second limiting grooves are opposite, the second floating rod 15 is adaptively accommodated between the two second limiting grooves, the axis of the second floating rod 15 is along the X direction, and the axis of the second floating rod 15 is perpendicular to the axis of the female head 10.

[0060] In this embodiment, preferably, through holes are formed in the middle of the first mounting plate 11, the second mounting plate 12 and the third mounting plate 13 for the female connector 10 to pass through. Two first floating rods 14 are arranged between the first mounting plate 11 and the second mounting plate 12, and the two first floating rods 14 are located on both sides of the through hole in the Z direction; two second floating rods 15 are arranged between the second mounting plate 12 and the third mounting plate 13, and the two second floating rods 15 are located on both sides of the through hole in the X direction.

[0061] When the three mounting plates of the female head mounting base 1 are not locked, the second mounting plate 12 can rotate relative to the first mounting plate 11 around the Z-axis of the first floating rod 14, thereby driving the third mounting plate 13 and the female head 10 to rotate around the first floating rod 14, so as to adjust the alignment deviation of the female head 10 in rotation around the Z direction. The third mounting plate 13 can rotate relative to the second mounting plate 12 around the X-axis of the second floating rod 15, thereby driving the female head 10 to rotate around the second floating rod 15, so as to adjust the alignment deviation of the female head 10 in rotation around the X direction.

[0062] When adjusting the alignment deviation of the female head 10 in translation along the Z direction, the second mounting plate 12 is adjusted so that the second mounting plate 12 is lifted and lowered relative to the first floating rod 14 of the first mounting plate 11 in the Z direction, thereby driving the third mounting plate 13 and the female head 10 to be lifted and lowered in the Z direction, so as to adjust the alignment deviation of the female head 10 in translation along the Z direction. When adjusting the alignment deviation of the female head 10 in translation along the X direction, the third mounting plate 13 is adjusted so that the third mounting plate 13 is translated relative to the second floating rod 15 of the second mounting plate 12 in the X direction, thereby driving the female head 10 to be translated in the X direction, so as to adjust the alignment deviation of the female head 10 in translation along the X direction.

[0063] When adjusting the alignment deviation of the female head 10 around the Y axis, the axis of the female head 10 is taken as the Y axis, the first floating rod 14 is taken out from between the first mounting plate 11 and the second mounting plate 12, and then the mounting angle of the second mounting plate 12 relative to the first mounting plate 11 is adjusted around the axis of the female head 10, so as to adjust the alignment deviation of the female head 10 by rotation around the Y axis. Since the aperture of the first connecting hole on the first mounting plate 11 is relatively large, when the second mounting plate 12 is rotated around the axis of the female head 10 by a predetermined angle, the second connecting hole on the second mounting plate 12 can still be opposite to the first connecting hole, so that the first screw can be inserted between the first mounting plate 11, the second mounting plate 12 and the third mounting plate 13 for fastening.

[0064] In this embodiment, preferably, Figure 2As shown, the female head mounting seat 1 also includes a pad. When the first floating rod 14 is removed, the pad can be placed between the first mounting plate 11 and the second mounting plate 12 to lift the second mounting plate 12 away from the first mounting plate 11 along one side of the X-direction, thereby causing the second mounting plate 12 to deflect around the axis of the Z-direction, thereby driving the third mounting plate 13 and the female head 10 to deflect around the axis of the Z-direction by a predetermined angle.

[0065] Similarly, a pad block can be placed between the second mounting plate 12 and the third mounting plate 13 to lift the third mounting plate 13 away from the second mounting plate 12 along one side of the Z direction, thereby causing the third mounting plate 13 to deflect around the axis of the X direction, thereby driving the female head 10 to deflect around the axis of the X direction by a predetermined angle.

[0066] Through the female head mounting seat 1 of the present application, the female head 10 can achieve a maximum alignment deviation of ±2.5° and ±2mm based on the alignment position of the female head 10 and the male head 20.

[0067] Regarding the above-mentioned lockable and unlockable universal floating male mounting seat 2, in one embodiment of the present application, preferably, as Figure 1 and Figure 3 As shown, the male mounting seat 2 includes a fourth mounting plate 21 and a fifth mounting plate 22. The fifth mounting plate 22 is fixed to the base 5 by a bracket 25. The fourth mounting plate 21 is arranged on the side of the fifth mounting plate 22 facing the female mounting seat 1. The male head 20 is mounted on the fourth mounting plate 21, and the fourth mounting plate 21 is mounted on the fifth mounting plate 22 by a universal floating member 23, so that the male head 20 can float by itself.

[0068] A second screw rod 24 , ie the locking member mentioned above, is also screwed onto the fifth mounting plate 22 . The axis of the second screw rod 24 is along the Y direction. Screwing the second screw rod 24 can move the second screw rod 24 closer to or away from the fourth mounting plate 21 along the Y direction.

[0069] The second screw 24 can be adjusted to be in close contact with the fourth mounting plate 21, thereby limiting the floating of the fourth mounting plate 21 relative to the fifth mounting plate 22, that is, locking the male mounting seat 2 so that the male head 20 cannot float by itself. When the second screw 24 is away from the fourth mounting plate 21, the universal floating function of the male mounting seat 2 is unlocked, so that the male head 20 can float by itself, and by adjusting the distance between the second screw 24 and the fourth mounting plate 21, the floating range of the fourth mounting plate 21 and the male head 20 can be adjusted, that is, the floating value of the male head 20 can be adjusted. Preferably, the male mounting seat 2 of the present application can provide a maximum unilateral unidirectional floating space of 3mm for the male head 20.

[0070] In this embodiment, the fourth mounting plate 21 and the fifth mounting plate 22 are both square, and their four vertex corners are arranged opposite to each other in a one-to-one correspondence, and a universal floating member 23 and a second screw rod 24 are arranged between every two opposite vertex corners.

[0071] In one embodiment of the present application, preferably, regarding the connection between the fifth mounting seat and the bracket 25, a fifth connecting hole is provided on the fifth mounting seat, and a sixth connecting hole is provided on the bracket 25 at a position opposite to the fifth connecting hole, so that a fastener can be passed between the fifth mounting seat and the bracket 25, so that the fifth mounting seat is fixedly installed on the bracket 25.

[0072] In this embodiment, preferably, Figure 3 As shown, the sixth connecting hole is a long hole, and the length direction of the sixth connecting hole is along the Z direction, so that the installation height of the fifth mounting seat on the bracket 25 along the Z direction is adjustable, so as to adjust the installation height of the male mounting seat 2 and the male head 20 in the Z direction; thereby, when adjusting the alignment deviation between the female head 10 and the male head 20 along the Z direction, in addition to adjusting the female mounting seat 1, the male mounting seat 2 can also be adjusted.

[0073] In one embodiment of the present application, preferably, Figure 4 As shown, the connector universal floating test device also includes a regulating component, which includes a pressure regulating valve 31, an electric proportional valve 32, a pressure regulating tank 33, a solenoid valve 35, a first speed regulating valve 36 and a second speed regulating valve 37.

[0074] The inlet of the pressure regulating valve 31 is connected to the external gas source, and the outlet of the pressure regulating valve 31 is connected to the inlet of the pressure stabilizing tank 33 through the electric proportional valve 32, and the pressure stabilizing tank 33 is provided with a pressure sensor 34 for detecting the pressure of the pressure stabilizing tank 33. The solenoid valve 35 is a two-position five-way solenoid valve, the driving cylinder 3 is a single-rod double-acting cylinder, the driving cylinder 3 includes a piston chamber and a piston rod chamber, and the outlet of the pressure stabilizing tank 33 is respectively connected to the piston chamber and the piston rod chamber through the solenoid valve 35. When the gas is input into the piston chamber, the driving end of the driving cylinder 3 can extend, and when the gas is input into the piston rod chamber, the driving end of the driving cylinder 3 retracts; at the same time, a first speed regulating valve 36 is provided on the gas path between the piston chamber and the solenoid valve 35, and a second speed regulating valve 37 is provided on the gas path between the piston rod chamber and the solenoid valve 35.

[0075] Therefore, with the cooperation of the pressure regulating valve 31 and the two speed regulating valves, the push-pull force and speed of the driving end of the cylinder 3 can be driven, so that it can be used to simulate the impact conditions commonly existing in various automatic docking conditions. At the same time, based on the detection values ​​of the pressure sensor 34 and the electrical performance, the recommended values ​​of the push-pull force and speed under extreme impact conditions can be obtained.

[0076] In the actual test of the universal floating test device for connectors of the present application, in step 1, the male and female heads are respectively installed to the corresponding male mounting seat and female mounting seat, and the axes of the female and male heads are made to coincide by adjusting the female mounting group and the male mounting seat, that is, the female and male heads are adjusted to the aligned position.

[0077] Step 2: According to the actual production process, the size and speed of the driving force of the driving cylinder are adjusted according to the docking requirements of the connector. When the male and female connectors are connected, the electrical performance tester is started to monitor the electrical performance signals such as the connector conduction / resistance, and the male and female connectors are separated after obtaining the values, and the plugging and unplugging force data is obtained through the pull pressure sensor. Repeat the above process and calculate the average of the obtained data.

[0078] Step 3: According to the estimated docking deviation in the actual production process, adjust the female connector mounting seat to simulate the multi-axis deviation of the female connector, and then repeat step 2 to analyze whether the connector can reach the estimated service life based on the test results.

[0079] Step 4, according to the estimated docking deviation in the actual production process, as well as the extreme conditions of impact force and impact speed, adjust in the manner of steps 2 and 3 to simulate the extreme deviation and extreme impact conditions, then complete the engagement and separation of the male and female connectors in a single operation, and determine the applicability and service life of the connector based on the data fed back by the tension and pressure sensor and the electrical performance tester; if the connector is damaged, replace the connector.

[0080] Step 5, loosen the second screw as much as possible to release the maximum floating space of the male head, maintain the deviation and impact of step 4, complete the connection and separation of the male head and the female head in a single time, and obtain the data fed back by the tension and pressure sensor and the electrical performance tester to confirm whether the connector can withstand the ultimate impact force. Then adjust the impact force in stages to obtain the allowable ultimate impact force. Then tighten the second screw in stages until the data fed back by the tension and pressure sensor and the electrical performance tester are close to the data obtained in step 2, and record the floating value (optimal floating value) of the male head at this time, that is, the gap between the second screw and the fourth mounting seat; continue to tighten the second screw until the feedback data is close to the data obtained in step 3, and record the floating value (recommended floating value) of the male head at this time.

[0081] In summary, the universal floating test device for connectors of the present application can be used to simulate the adaptability of non-floating and self-floating male connectors in the automatic docking conditions of connectors under various axis deviations, as well as to detect the plugging and unplugging force, electrical performance and service life of connectors under these conditions. At the same time, it can be used to simulate the impact conditions commonly found in various automatic docking conditions, and obtain recommended values ​​for extreme impact conditions. At the same time, after the universal floating of the male connector is unlocked, the recommended floating value that adapts to actual production needs can be given through testing.
