The movable contact position adjusting mechanism is arranged on the movable connector, so that when the pair of movable contacts 1 and 1 'are inserted into or separated from the static connector 3, the pair of movable contacts 1 and 1' are correspondingly contacted or separated from the static connector 3, the contact process of the pair of movable contacts 1 and 1 'and the static connector 3 is shortened, and the purpose of reducing the abrasion between the pair of movable contacts 1 and 1' and the static connector 3 is achieved.

Further, as shown in fig. 2 and 4, the movable contact position adjustment mechanism includes a sliding block 4, and the pair of movable contacts 1,1 'is rotatably mounted on the sliding block 4, specifically, in this embodiment, the pair of movable contacts 1, 1' is mounted on the sliding block 4 by a pair of contact rotating shafts 5,5 'and can rotate around the pair of contact rotating shafts 5, 5'.

According to the low-abrasion movable connector provided by the embodiment of the utility model, the movable contact position locking and unlocking adjusting mechanism is additionally arranged on the movable connector, so that the opening and closing distance between the movable contacts at two sides can be accurately controlled, the condition that the sliding process of plugging is free of contact and friction is realized, the movable contacts clamp the fixed contacts to be conducted after plugging is in place, and the movable contacts are preferentially opened in the separation process to realize the non-contact in the separation sliding process so as to realize no abrasion. The whole process only has the trace abrasion of the moving contact and the static contact which must be contacted in a conducting state.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, those skilled in the art will appreciate that; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
