Description

TECHNICAL FIELD

[0001] The application relates to the technical field of shunters, in particular to a twisted and bent special shunter. BACKGROUND

[0002] A shunter is a precision component, and its design is based on the principle that a direct current passing through a resistor generates a voltage. The shunter is usually connected in parallel with a current circuit of a measuring instrument to expand the measuring range. The working principle of the shunter is deeply rooted in Ohm's law and the shunt principle, that is, the current is proportional to the voltage across the resistor, and in a parallel circuit, the current shared by each resistor is inversely proportional to its resistance.

[0003] In the related technical practice, a plurality of threaded holes are usually arranged on the shunter body so as to fix the line board assembly thereon. The line board assembly is pre-formed with through holes corresponding to the threaded holes. During assembly, small fastening screws are used to be screwed into the threaded holes of the shunter through the through holes of the line board assembly to realize fixation.

[0004] However, since the size of the shunter and the line board assembly is relatively compact, the required fastening screws are correspondingly small in size, which undoubtedly increases the assembly difficulty. Specifically, not only is it required to accurately align the through holes and the threaded holes, but also the screw tightening operation is quite tricky, thereby reducing the assembly efficiency and leaving room for improvement. CONTENT OF THE UTILITY MODEL

[0013] Optionally, an elastic protective pad is fixedly arranged on the side surface of the limiting plate facing the shunt body.

[0014] By adopting the technical scheme, when the limiting plate is rotated to above the shunt body and abuts against the surface of the circuit board assembly, the elastic protective pad is arranged to reduce the possibility of scratching the surface of the limiting plate.

[0015] Optionally, a guide inclined surface is arranged on the side surface edge of the limiting plate facing the shunt body.

[0017] Optionally, anti-skid lines are uniformly arranged on the side surface of the limiting plate away from the shunt body.

[0018] By adopting the technical scheme, when the worker controls the rotation of the limiting plate, the anti-skid lines arranged on the limiting plate can improve the static friction force between the fingers of the worker and the upper side surface of the limiting plate, so as to facilitate the rotation control of the limiting plate.

[0019] Optionally, an engaging rod is arranged on the side surface of the shunt body, an engaging groove is arranged on the side surface of the shunt body away from the conductive pin, the engaging rod is inserted into the engaging groove, a bent rod is fixedly arranged on the end portion of the engaging rod away from the conductive pin, the length direction of the bent rod is parallel to the length direction of the engaging rod, and one end of the limiting plate is rotationally connected to the end portion of the bent rod.

[0020] By adopting the technical scheme, when the engaging rod and the shunt body are installed and fixed, the engaging rod is inserted into the engaging groove on the shunt body by force, and then the limiting plate is installed on the end portion of the bent rod, so as to realize the rotation connection between the limiting plate and the shunt body.

[0021] Optionally, a clamping hook is arranged on the outer periphery of the end of the connecting rod, and a clamping groove is arranged on the inner wall of the connecting groove for the clamping hook to be inserted into.

[0022] By using the above technical scheme, after the connecting rod is inserted into the connecting groove on the shunt body, the clamping hook on the connecting rod is inserted into the clamping groove on the inner wall of the connecting groove due to the matching arrangement of the clamping hook and the clamping groove, so that the installation stability of the connecting rod in the connecting groove is improved.
