Description

Technical Field

[0001] The utility model belongs to the technical field of electrical component experiments, and particularly relates to an insertion and extraction force experiment device. Background Art

[0002] The plugging and unplugging force refers to the insertion and unplugging force required when the male and female ends are mated in electronic and other types of connectors. This is an important indicator to measure the ease of use and durability of connectors. Specifically, it refers to the force required to insert the male head of the connector into the female head. A good design should ensure that this force is not too large so that the user can operate it easily. It refers to the force required to unplug the male head of the connector from the socket. This force needs to be large enough to maintain the stability of the connection, but not too large to avoid damaging the connector or causing difficulties to the user. The plugging and unplugging force test device, usually called a plugging and unplugging force tester or a plugging and unplugging force tester, is a device dedicated to measuring the insertion and unplugging force of electronic connectors, terminals, connectors and other products.

[0003] The existing plug-in and pull-out force test device uses a fixing mechanism to fix the connector for plug-in and pull-out tests. However, the fixing mechanism that fixes the connector with bolts is not easy to disassemble. When it is necessary to fix and plug connector samples of different sizes, the fixing mechanism needs to be replaced. However, it requires manual tightening or loosening of the bolts, which consumes a lot of time and reduces the test efficiency. Frequent tightening and loosening of the bolts may cause physical exhaustion of the operator, and long-term work may easily cause fatigue. Utility Model Content

A locking column, locking holes are respectively provided on the front and rear sides of the two sliding blocks, and the four locking columns are respectively plugged into adjacent locking holes.

The upper ends of the two cavity blocks are respectively provided with a rotating frame through a telescopic column, and the two front and rear adjacent connecting frames are respectively rotatably connected to the adjacent rotating frames. An elastic driving unit is provided between the cavity block and the rotating seat, and the elastic driving unit includes a spring arranged between the cavity block and the rotating seat. The four springs are respectively sleeved on the corresponding outer arc surfaces of the locking columns. The moving and fixing mechanism includes screws that are respectively threaded and rotated inside the two sliding blocks, and the lower ends of the two screws are respectively rotatably connected to the adjacent sliding plates.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] First, by placing the connector plug on the docking plate on the left, and then rotating the knob on the left to rotate the screw, driving the sliding plate to move downward to cooperate with the docking plate to achieve fixed limit of the connector plug, and then placing the connector docking head on the right docking plate according to the above method to achieve fixation of the docking head, so that the positions of the plug and the docking head correspond, and then control the control panel to turn on the electric push rod, the telescopic end drives the plug on the moving plate to move to the right and insert it into the interior of the docking head, and then the telescopic end is contracted to make the plug move to the left and leave the interior of the docking head, and this reciprocating process is repeated to quickly test the plug-in and pull-out force of the connector.

[0010] Secondly, by pressing the rotating frame, the connecting frame inside it rotates and expands, thereby driving the locking columns on the rotating seats on both sides to leave the locking holes of the sliding block. Then the fixing mechanism on the sliding block can be disassembled.
