Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-7, an apparatus for detecting the accuracy of a mouse PCB and electrical equipment includes a housing (1), wherein two side walls of the housing (1) are provided with connecting slots (16), and the length of each connecting slot (16) is greater than that of the PCB; the surface of the connecting groove (16) is fixedly connected with flexible cloth which has the function of preventing the PCB from being scratched and damaged when the PCB is contacted with the connecting groove (16); the inner part of the shell (1) is movably connected with a rotary table (2), the inner part of the rotary table (2) is movably connected with a ball (3), and a groove (13) is formed in the joint of the rotary table (2) and the ball (3).
The size of the groove (13) is matched with that of the ball (3), the groove (13) can provide a certain space for the movement of the ball (3), and the ball (3) is circular, so that the ball is in point contact with a PCB (printed circuit board); the quantity of ball (3) is ten, and evenly distributed is in the inside of carousel (2), and ball (3) are a little higher than the surface of carousel (2), contact with the PCB board when being convenient for ball 3 to rotate.
The surface of the ball (3) is movably connected with an elastic rod (4), and the centrifugal force generated by the rotation of the turntable (2) is smaller than the elastic force of the elastic tube (4), so that the elastic deformation distance of the elastic tube (4) is not too large; the surface swing joint of elastic rod (4) has adjusting collar (5), card hole (15) have been seted up on the surface of adjusting collar (5), and the size of card hole (15) and the radius looks adaptation of elastic rod (4) through removing elastic rod 4 position in card hole 15, can realize the effect of regulation and control elastic rod 4 elasticity, make its better cooperation ball 3 remove.
The equal swing joint in both sides of ball (3) has accepts board (6), accept one side swing joint that ball (3) were kept away from in board (6) and have spring beam (7), the one end swing joint that accepts board (6) was kept away from in spring beam (7) has elasticity board (8), and the surperficial swing joint of spring beam (7) has contact piece (9), after contact piece 9 was given certain electric quantity, according to the magnetic effect of electric current, it can produce weak electric current when near with the metal block distance on PCB board surface, utilize this weak electric current can realize not with PCB board contact alright realize detecting its electric effect.
