[0036] In a preferred but non-limiting embodiment of this utility model, the fixing frame 4, the reinforcing rib 8, the floating module 3, and the RJ45 plug clamp 2 are all made of 6061 type aluminum alloy material.
[0037] The overall structure of this mechanism is simple, low in cost, and easy to promote and apply. The floating module 3 has a certain amount of floating in the X, Y, and Z directions relative to the fixed frame 4, realizing the floating functions of up, down, left, right, front, and back. When the RJ45 plug 1 is clamped between the upper clamp and the lower clamp, a small gap is reserved between the upper clamp, the lower clamp and the RJ45 plug 1, so that the RJ45 plug 1 has a certain amount of movement, preventing the RJ45 plug clamp 2 from jamming with the RJ45 plug 1 during connection.
[0038] Working principle:
[0039] When a network switch needs to undergo communication testing, the RJ45 plug 1 is clipped onto the RJ45 plug clamp 2. Using the connection holes, this device is fixed to a three-axis motion robot, fixture, or robotic gripper. Fixing screws can be passed through the connection holes to connect and secure it to the automated equipment. The automated equipment then moves the device forward. When the RJ45 plug 1 contacts the RJ45 socket of the switch, due to dimensional deviations in the electrical or structural components, the RJ45 plug 1 and the RJ45 socket are difficult to align perfectly. The RJ45 socket presses against the RJ45 plug 1, allowing the plug 1 to pass through... The RJ45 plug clamp 2 drives the floating module 3 to move synchronously. While the floating module 3 moves synchronously with the RJ45 plug 1, it does not affect the forward movement of the fixed frame 4 driven by the automated equipment. The floating module 3 applies forces in the X, Y, and Z directions to the spring 6. Since the floating module 3 and the fixed frame 4 are connected by the spring 6 and the shoulder screw 5, the floating module 3 can automatically float relative to the fixed frame 4 in the X, Y, and Z directions. The RJ45 plug 1 and the RJ45 socket can be precisely connected to achieve a reliable electrical connection of the communication port. At the same time, the floating in the Z direction can avoid over-insertion and prevent damage to the RJ45 socket.
[0040] The beneficial effect of this utility model is that, compared with the prior art,
[0041] 1. No manual connection of RJ45 plug and RJ45 socket is required. The RJ45 plug is automatically aligned with the RJ45 socket by floating in the X and Y directions. The automated test connection is highly reliable, reduces the failure rate of the automated connection between the RJ45 plug and socket, and improves the efficiency of automated testing.
[0042] 2. Automatic floating in the Z direction prevents over-insertion of the RJ45 plug and avoids damage to the RJ45 socket.
