Description

Technical Field

[0001] The utility model relates to the technical field of displacement sensors, and particularly relates to a displacement sensor. Background Technique

[0002] The function of a linear displacement sensor is to convert a linear mechanical displacement into an electrical signal. To achieve this effect, a variable resistance slide rail is usually fixed at a fixed part of the sensor, and different resistance values are measured by the displacement of a sliding piece on the slide rail. The sensor slide rail is connected to a steady DC voltage, allowing a small current of microamperes to flow through. The voltage between the sliding piece and the starting end is proportional to the length of the sliding piece's movement. Using the sensor as a voltage divider can minimize the requirement for the accuracy of the total resistance value of the slide rail because the resistance change caused by temperature change will not affect the measurement result.

[0003] The prior art has the following defects and deficiencies:

[0004] The existing shielding cover adopts a crimping method. The coating of the shielding cover is easily worn during crimping, resulting in the product not meeting the salt spray requirements. During production wiring, wiring is required, and the wires at the tail of the socket are easily wound and damaged during the process of rotating and installing the socket. Therefore, a displacement sensor is proposed. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a displacement sensor, which solves the existing problems.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A displacement sensor includes a sensor body. One end of the sensor body is provided with a shielding layer, and a flange ring is fixedly connected to the outside of the shielding layer. One end of the sensor body is provided with an installation interface. An opening is provided on the outside of the sensor body, and a fixing plate is fixedly connected to the inside of the opening. A socket interface is fixedly connected to the top of the fixing plate.

[0007] Preferably, the flange ring is diamond-shaped, and the socket of the installation interface is far from the flange ring.

[0008] Preferably, the opening is provided on the side of the tail of the sensor body, and threaded holes are provided inside the fixing plate.

[0009] Advantageous Effects

[0010] The utility model provides a displacement sensor. Compared with the prior art, it has the following advantageous effects:

[0011] 1. This displacement sensor is provided with a flange ring, and the shielding layer is located below the flange ring. During installation, it only needs to be fixed in cooperation through the flange ring, without the traditional crimping fixation method, so that the coating of the shielding layer will not be subjected to friction and extrusion, and the service life of the shielding layer on the displacement sensor can be longer.

[0012] 2. This displacement sensor is provided with an opening, a fixing plate and a socket interface. The socket interface is installed on the side of the tail end of the sensor body, so that there is no need to wire and install a socket. It can directly connect the socket interface with the connecting object, avoiding the subsequent steps of wiring and installing a socket, which is not only simpler but also avoids the wires being easily wound and damaged during the installation process by the user.
