[0046] Specifically, please refer to Figure 1 And Figure 2In the embodiment, the plug plugging detection jig 100 comprises a base 1, a plug fixing assembly 2 and a socket fixing assembly 3; the plug fixing assembly 2 is arranged on the base 1 and is used for fixing the plug 200 thereon and is adapted to hold the bottom of the plug 200; the socket fixing assembly 3 is arranged on the base 1 and is used for fixing the socket 300 thereon and is adapted to hold the bottom of the socket 300; at least one of the plug fixing assembly 2 and the socket fixing assembly 3 is movably arranged, so that the plug fixing assembly 2 and the socket fixing assembly 3 have a plugging state of approaching each other and making the plug 200 and the socket 300 on them be plugged, and have a unplugging state of moving away from each other and making the plug 200 and the socket 300 on them be unplugged.

[0047] In the embodiment, the plug fixing assembly 2 is used for fixing the plug 200 therein, and the socket fixing assembly 3 is used for fixing the socket 300 thereon; at least one of the plug fixing assembly 2 and the socket fixing assembly 3 is movably arranged, so that the plug fixing assembly 2 and the socket fixing assembly 3 can move relatively, the plug fixing assembly 2 and the socket fixing assembly 3 can approach each other, so that the plug 200 and the socket 300 on them can be plugged, the plug fixing assembly 2 and the socket fixing assembly 3 can move away from each other, so that the plug 200 and the socket 300 on them can move away from each other, to achieve the unplugging of the plug 200 and the socket 300; and the plug fixing assembly 2 can hold the bottom of the plug 200, and the socket fixing assembly 3 can hold the bottom of the socket 300, so that the plug 200 and / or the socket 300 cannot be displaced downward under the gravity or the clamping loosening in the process of multiple plugging and unplugging, and the alignment accuracy of the plug 200 and the socket 300 is better guaranteed. The bottom here refers to the surface in the lower direction of the gravity. The plug plugging detection jig 100 provided by the utility model can repeatedly achieve the plugging and unplugging of the plug 200 and the socket 300 by the approaching and moving away of the plug fixing assembly 2 and the socket fixing assembly 3 multiple times, so that the plugging and unplugging performance of the plug 200 and the socket 300 can be detected stably and effectively, the plugging and unplugging detection data of the plug 200 and the socket 300 can be better acquired, and accurate and reliable detection results can be obtained.

[0048] It can be understood that, in an embodiment, the plug fixing assembly 2 and the socket fixing assembly 3 can be movably arranged on the base 1 synchronously or successively, to realize the approaching or moving away of the two, and to realize the plugging and unplugging of the plug 200 and the socket 300.

[0049] In another embodiment, only one of the plug fixing component 2 and the socket fixing component 3 is movably disposed on the base 1.

The movable block 31 can be moved manually or by a driving device. The movement of the movable block 31 causes the first fixing plate 32 and the first mounting plate 33 located thereon to move together, thereby causing the socket 300 located on the first mounting plate 33 to move closer to or further away from the plug 200 located on the plug fixing assembly 2.

[0054] Furthermore, combined Figures 3 to 5As shown, the first mounting plate 33 comprises a mounting bottom plate 331, a mounting side plate 332, and a first guide slot 333 and a second guide slot 334 formed on the opposite sides of the mounting side plate 332, the mounting side plate 332 is fixed on the first fixed plate 32, the first guide slot 333 is protruded from the first fixed plate 32 and is arranged towards the docking area, the second guide slot 334 is through the first guide slot 333 and is protruded on the other side of the mounting side plate 332, and the second guide slot 334 is used for accommodating at least part of the socket 300.
