The displacement of the axial force detection head 12 and the sliding seat 121 on the transverse sliding rail 111 is adjusted, so that the transverse displacement of the universal joint 124 and the axial sensor 123 can be adjusted; the axial displacement of the universal joint 124 and the axial sensor 123 can be adjusted by adjusting the displacement of the sliding block 122 on the axial sliding rail 1211 on the top surface of the sliding seat 121.

Referring to fig. 1, 4 and 5, a plug to be tested is mounted on the plug cavity 141 of the plug mounting base 14.

The socket cavity 221 of the socket mounting base 22 is provided with a positional deviation, and the socket to be tested is mounted on the socket cavity 221 of the socket mounting base 22.

Referring to fig. 1, when the linear module 23 of the external force transmission mechanism 2 is started, the driving rod of the linear module 23 drives the carriage 211 to move along the track through the connecting rod 24, the carriage 211 drives the socket mounting seat 22 to move, when the socket to be detected in the socket inner cavity 221 is in butt joint with the plug to be detected in the plug inner cavity 141, the axial force applied to the socket mounting seat 22 triggers the axial sensor 123 through the universal joint 124, and the axial contact force when the plug is plugged into the socket can be obtained by reading the information value on the axial sensor 123;

in addition, because the socket cavity 221 is provided with a position deviation, the deviation of the socket to be detected forces the plug to be detected and the plug mounting seat 14 to generate radial displacement, so that one side or two sides of the rectangular block of the plug mounting seat 14 trigger the radial sensor 15 arranged on the corresponding side of the bent plate bracket 11, and the radial contact force of the corresponding surface when the plug is plugged with the socket can be obtained by reading the information value on the radial sensor 15.

The contact force generated by different position deviations is detected by the invention, so that a reliable design basis can be provided for the tolerance range of the position deviation of the two butting ends of the electric connector.

The invention detects the contact force generated by different position deviations, and the invention sets different position deviations on the socket inner cavity 221 of the socket mounting seat 22, wherein the position deviations comprise the deviation generated by coordinate translation, the deviation generated by coordinate rotation or the composite deviation generated by coordinate translation and rotation.

The invention solves the problem of contact force detection of each direction when the connector is plugged in and pulled out in the limit deflection state, and provides a basis for verifying the reliability of product design and the service life of the product.

Referring to fig. 1, in order to ensure the sensitivity of the radial displacement of the plug mounting seat 14, the plug mounting seat 14 is disposed between a plurality of radial sensor seats 113 of the bent plate bracket 11, and the peripheries of the rectangular blocks of the plug mounting seat 14 are respectively in contact with the radial sensors 15 disposed on the peripheries of the bent plate bracket 11. In addition, the connector connecting seat 142 on the plug mounting seat 14 passes through the window 112 to be connected with the universal connector 124 of the axial force detecting head 12, and is connected with the axial sensor 123 through the universal connector 124. Due to the arrangement of the universal joint 124, it is ensured that only axial forces are transmitted between the plug mounting 14 and the axial sensor 123, while the universal joint 124 does not constrain the radial displacement of the plug mounting 14.

The invention adopts the positioning reference of the shape and the position of the socket inner cavity 221 on the socket mounting seat 22 to float relative to the outer contour reference dimension of the socket mounting seat 22, the reference of the socket inner cavity 221 is the floating reference, and the floating amount is designed according to the deviation set during the butt joint test of the floating connector. In the floating connector, floating is realized by the wave springs in the respective degree directions, when the plug and the socket are inserted in a relative deflection state, not only are insertion force and extraction force in the axis direction, but also longitudinal acting force and transverse acting force which are mutually perpendicular to the axis direction are provided, and in order to check the reliability of the design of the wave springs in the respective degree directions, not only the axial force for inserting and extracting the plug and the socket but also the longitudinal acting force and the transverse acting force need to be detected. In order to facilitate detection, the socket can be arranged at any position of six degrees of freedom of translation or rotation relative to the plug, the deflection states of the socket and the plug are respectively detected, and the test requirement on the limit deflection position of a product is met.
