Description

Technical Field

[0001] The utility model relates to the technical field of socket detection, in particular to a socket extraction force testing device. Background Art

[0002] In order to ensure that the structure of the socket should make the plug easy to insert and unplug, and should prevent the plug from falling out of the socket during normal use, the socket needs to undergo maximum pull-out force and minimum pull-out force tests. GB / T 2099.1-2021 provides a basic detection device for the maximum pull-out force test of the socket. When the existing detection device performs the maximum pull-out force test of the socket, if the socket is qualified, the plug will fall out of the socket after the weight is applied, and there is a risk of the weight falling and rolling around, which is dangerous for the operator. For this reason, we provide a socket pull-out force test device to solve the above problems. Utility Model Content

[0026] The working principle of this application is:

[0027] First, the socket to be tested is clamped by the clamping member 4 at the top, and then the plug 5 is inserted into the socket, the main weight 12 and the additional weight 11 are set on the threaded connecting rod, and then the threaded connecting rod is fixedly connected to the threaded connecting head, and the height of the bottom tray 13 is adjusted by rotating the threaded connecting rod, so that the tray 13 or the main weight 12 is pressed on the lower support plate 10, and then the transparent shield 1 is put on the device body, and the electromagnetic block 17 is energized. After the electromagnetic block 17 is energized, the permanent magnet block 19 is attracted to make the lower support plate 10 retract, and the reset spring 18 is compressed, and the lower support plate 10 no longer supports the main weight 12 or the tray 13. If the plug 5 falls off, it means it is qualified, and if the plug 5 does not fall off, it means it is unqualified;

[0028] Components such as the main weight 12, the additional weight 11, the plug 5 and the hanging ring 6 fall into the collection frame.

[0029] When a drop test is required, an additional weight 11 is also sleeved on the threaded connecting rod, and the upper support plate 8 is fixedly connected to the lower support plate 10 through a connecting rod, and the additional weight 11 is pressed onto the upper support plate 8. By adjusting the height of the connecting rod to 50 mm, the distance between the upper support plate 8 and the lower support plate 10 is 50 mm. Then the tray 13 or the main weight 12 is adjusted to be pressed onto the lower support plate 10, and then the transparent protective cover 1 is put on the device body, and the electromagnetic block 17 is energized. After the electromagnetic block 17 is energized, the permanent magnet block 19 is adsorbed to retract the lower support plate 10 and the upper support plate 8. The additional weight 11 falls on the main weight 12. If the plug 5 falls, it indicates that the specifications are met. If the plug 5 does not fall, it indicates that the specifications are not met. By setting a collection frame, the fallen plug 5, hanging ring 6 and counterweight can be prevented from injuring the staff. The test is more intuitive by controlling the electronic control device.
