[0041] Please refer to Figures 1 to 4 As shown, it shows the specific structure of a preferred embodiment of the present invention, including a frame 10, an electrical testing host 20, a movable carrier 30, a matching head 40 and a pressing head 50.

[0042] The frame 10 includes a base 11 and a cover 12; two slide rails 13 are provided on the surface of the base 11, and the two slide rails 13 are arranged separately on the left and right and extend forward and backward. A storage box 14 is provided on one side of the base 11, and a plurality of supporting legs 15 are provided on the bottom of the base 11. The cover 12 is set on the base 11, and a window 121 is opened on the front side of the cover 12. The cover 12 is a transparent safety protective cover.

[0043] The electrical testing host 20 is mounted on the frame 10. In this embodiment, the electrical testing host 20 is mounted on top of the housing 12. The electrical testing host 20 includes a touch screen 21, an alarm 22, a stop switch 23, and a power switch 24. Furthermore, start switches 25 are provided on both the left and right sides of the base 11. Both start switches 25 are electrically connected to the electrical testing host 20.

[0044] The movable platform 30 can be movably arranged on the frame 10 in a forward and backward manner. The movable platform 30 has a placement position 31 for placing the communication connector 60. The movable platform 30 is driven by a first drive mechanism 71 to move back and forth. The first drive mechanism 71 is electrically connected to the electrical measurement host 20. In this embodiment, the movable platform 30 and the first drive mechanism 71 are both arranged on the base 11 and covered by the hood 12. In addition, the movable platform 30 can be slidably arranged on two slide rails 13 in a forward and backward manner, so that the movable platform 30 can move more smoothly and with higher precision. In addition, the first drive mechanism 71 is a cylinder. The first drive mechanism 71 is located at the rear between the two slide rails 13, and the drive is smooth and fast. In addition, the window 121 is directly opposite the movable platform 30 in front and back, so that the communication connector 60 can be taken in and put away.

[0045] The pair of mating heads 40 are arranged on the left and right sides of the machine frame 10, and are respectively positioned on the left and right sides of the movable platform 30. Each pair of mating heads 40 is driven by a second drive mechanism 72 for reciprocal movement. Each second drive mechanism 72 is electrically connected to the electrical testing host 20. Each pair of mating heads 40 includes a movable seat 41, a test circuit board 42, and a plug connector 43. The test circuit board 42 is mounted on the movable seat 41 and electrically connected to the electrical testing host 20. The plug connector 43 is mounted on the test circuit board 42 and electrically connected to the test circuit board 42. In this embodiment, the pair of mating heads 40 and the second drive mechanism 72 are both mounted on the machine frame 11 and are enclosed by the machine cover 12. The second drive mechanism 72 is a double-rod cylinder, which provides smooth and fast actuation. The test circuit board 42 includes a first circuit layer 421, a second circuit layer 422, and a third circuit layer 423. The first circuit layer 421, the second circuit layer 422, and the third circuit layer 423 are stacked up and down in sequence to form a first detection point 401 for detecting the conductivity of the shielding shell, a second detection point 402 for detecting the conductivity, insulation, and withstand voltage of the signal pin, and a third detection point 403 for detecting the conductivity, insulation, and withstand voltage of the power pin. The first detection point 401, the second detection point 402, and the third detection point 403 are all electrically connected to the electrical testing host 20. In this way, the conductivity, insulation, and withstand voltage of all power pins, all signal pins, and the shielding shell of the communication connector 60 can be tested simultaneously.

[0046] The pressing head 50 is movably mounted on the frame 10 and positioned above the movable platform 30. The pressing head 50 is driven by a third drive mechanism 73 for up and down movement. The third drive mechanism 73 is electrically connected to the electrical testing host 20. In this embodiment, the pressing head 50 and the third drive mechanism 73 are both located within the housing 12. The third drive mechanism 73 is a double-rod pneumatic cylinder, providing smooth and rapid actuation.

[0047] The working principle of this embodiment is described in detail as follows:

[0048] First, turn on the power switch 24 and place the communication connector 60 on the placement position 31 of the movable carrier 30. Then, press the start switches 25 on the left and right sides. Then, the first drive mechanism 71 drives the movable carrier 30 to slide backward to the test position. At this time, the communication connector 60 is located directly below the down-pressing head 50. Then, the third drive mechanism 73 drives the down-pressing head 50 to move downward and press the communication connector 60 to prevent the communication connector 60 from floating up and causing damage to the mating. Then, the two second drive mechanisms 72 respectively drive the mating heads 40 to move close to the two sides of the movable carrier 30, so that the plug-in connectors 43 on the two pairs of mating heads 40 are mated and connected to the two ends of the communication connector 60. At this time, the communication connector 60 is connected to the test circuit of the test circuit board 42, and all power pins, all signal pins and their shielding shells of the communication connector can be subjected to conduction, insulation and withstand voltage tests. The test data is processed and judged by the electrical testing host 20.

[0049] When the communication connector 60 is tested as a good product, the two second driving mechanisms 72 respectively drive the mating head 40 away from the movable carrier 30 and return to the original position, and then the third driving mechanism 73 drives the pressing head 50 to move upward and return to the original position. Then, the first driving mechanism 71 drives the movable carrier 30 to move forward, so that the movable carrier 30 is pushed out of the window 121. At this time, the communication connector 60 tested as a good product can be manually placed into the good product box.

[0050] When the communication connector 60 is tested as a defective product, the alarm 22 sounds an alarm and locks the object to be tested in the test position. The stop switch 23 must be pressed to push the defective product out, thereby preventing the defective product from flowing out due to human error.

[0051] The design focus of the utility model is: by using a lower pressure block to press the communication connector against the movable carrier, and cooperating with the provision of two pairs of mating heads, the two ends of the connector can be connected respectively by using the two pairs of mating heads, so as to test the conductivity, insulation and withstand voltage of all power pins, all signal pins and the shielding shell of the communication connector, without the need to use multiple devices, which is conducive to improving test efficiency, while also reducing cost investment, bringing convenience to production enterprises.

[0052] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
