[0002] In modern times, with the development trend of industrial automation and intelligence, the Industrial Internet has become a mature technology that connects all operating units. Among them, sensors have become an indispensable part, such as temperature, humidity, vibration, force and torque sensors.

[0003] For the industrial Internet, sensors play an important role in end-point sensing. However, there are many types of sensors. For mechanical sensors, installing the sensor on the object to be measured is a very important technology. The sensor sensitive unit is usually connected by tightening or fitting. The connection method must efficiently transmit mechanical energy. How the mechanical energy on the object to be measured is effectively transmitted to the sensor sensitive unit depends on the material integrity and integrity of its connection interface, and is also closely related to the rigidity and elasticity of its connection interface.

[0004] There are four common ways to connect sensor sensitive units, namely screw fastening, rivet fixing, welding and adhesive taping. Different connection methods will cause changes in sensor detection values, such as accuracy, sensitivity, hysteresis, linearity and repeatability. Welding is the method with the least mechanical energy transmission loss, but welding is quite inconvenient in actual product use, and requires surface treatment and coating on the object to be tested. Adhesive taping requires cleaning the surface of the object to be tested, applying a uniform thickness of adhesive, and then curing, which is quite time-consuming and labor-intensive.

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0036] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0037] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
