Plug-in type load cell

The utility model relates to a plug-in sensor. A strain sheet 6 is pasted on a sensitive area 2 internally connected with a cylindrical body, the cylindrical body is provided with a deformation zone 1, and the peripheral wall of the deformation zone 1 is radially symmetrically and uniformly circumferentially provided with four convex edges 3. the two sides of the deformation zone 1 are provided with a groove-shaped isolation zone 4, and the outer walls of the convex edges 3 incline to form a part of a conical surface; the cylindrical body is filled with seal gum, wherein, a compensation plate 5 is buried in the seal gum 8, and one end of the cylindrical body is connected with a cable segment 7. The utility model can be arranged on components, the external force received by the components can be measured, the measuring error is small, and the sensitivity is high.
