Description

Technical Field

[0001] This invention relates to the field of sensor mounting technology, and in particular to a sensor mounting structure and a device under test. Background Technology

[0002] Hydraulic transmission systems increase force by changing pressure. To prevent hydraulic pressure from exceeding a threshold, sensors are now used to detect the hydraulic pressure in the system. Detecting hydraulic signals requires installing sensors, which are mounted on the workpiece under test (DUT) to measure the hydraulic pressure at that DUT.

[0003] Currently, hydraulic pressure sensors come in two types: integral and split.

[0004] Since the sensor probe and the tail cable are independent of each other, and the probe and cable are connected by a pin, the problem of repeated disassembly and assembly of bare wire terminals can be effectively avoided. However, since the middle part is connected by a pin, frequent plugging and unplugging can lead to unstable signal contact and high product processing costs.

[0005] To improve the stability of signal acquisition, integrated sensors are typically used. However, because the sensor probe and tail cable are integrated into a single structure, integrated sensors are not suitable for scenarios requiring frequent disassembly and reassembly. Since the sensor tail cable is usually connected to bare wire terminals, when changing the test object, the sensor needs to be removed from the device under test. This requires disconnecting the bare wire terminals at the end of the sensor cable from the terminal block of the sensor signal acquisition module, which significantly impacts work efficiency. Furthermore, the disassembly and reassembly process can easily damage the cable, affecting the sensor's lifespan. Conversely, forcibly unscrewing the sensor without disconnecting the cable can also easily damage the cable.

[0006] Therefore, there is an urgent need to provide a sensor mounting structure to solve the problem of inconvenient assembly and disassembly of integrated sensors. Summary of the Invention

[0007] The purpose of this invention is to provide a sensor mounting structure that solves the problem that cables are easily damaged and the lifespan of the sensor is affected when the sensor is removed.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] A sensor mounting structure, comprising:

[0010] The first fixing member is detachably mounted on the test piece, and the sensor is movably mounted on the first fixing member;

[0011] The second fixing member is used to fix the sensor to the first fixing member.

[0012] Preferably, the first fixing member includes a sleeve with threads on its outer side wall, the sleeve being able to be fitted onto the sensor and screwed onto the test piece.

[0013] Preferably, the inner wall of the sleeve is a smooth surface.

[0014] Preferably, the second fixing member includes a convex ring, the outer diameter of which is larger than the inner diameter of the sleeve. When the sensor passes through the sleeve, the convex ring is installed at the probe end of the sensor so that the sensor does not detach from the sleeve.

[0015] Preferably, the connection between the convex ring and the sensor is a threaded connection.

[0016] Preferably, the second fixing member includes a boss disposed at the probe end of the sensor, the outer diameter of the boss being larger than the inner diameter of the sleeve.

[0017] Preferably, the outer side wall of the end of the sleeve that is screwed to the test piece is provided with a recessed platform along the circumference.

[0018] Preferably, the first fastener is made of metal.

[0019] The purpose of this invention is to provide a device under test that optimizes the structure of the device under test and improves the user experience.

[0020] To achieve this objective, the present invention adopts the following technical solution:

[0021] A device under test includes a test piece and the aforementioned sensor mounting structure disposed on the test piece.

[0022] Preferably, the test piece includes a hydraulic block with a groove and a through hole at the bottom of the groove. The first fixing member is installed in the groove, and the probe of the sensor is positioned facing the through hole.

[0023] The beneficial effects of this invention are:

[0024] In the sensor mounting structure provided by this invention, the first fixing member is detachably mounted on the test piece, and the sensor is movably mounted on the first fixing member; the second fixing member is used to fix the sensor on the first fixing member. The first fixing member, the second fixing member, and the sensor can all be separated from each other. When removing the sensor, only the first fixing member and the second fixing member need to be removed. The disassembly and assembly steps are simple, highly flexible, and unlikely to damage the sensor, thus extending the service life of the sensor.

[0038] Example 1

[0039] This embodiment provides a device under test, including a test piece 3 and a sensor mounting structure disposed on the test piece 3.

[0040] Specifically, such as Figure 1 As shown, the device under test 3 includes a hydraulic block with a groove 31 on it. A through hole 32 is provided at the bottom of the groove 31. The sensor is installed in the groove 31 through a sensor mounting structure. The sensor includes a probe 1 and a cable 2, and the probe 1 and the cable 2 are fixedly connected. The probe 1 of the sensor is set facing the through hole 32. The probe 1 can measure the hydraulic pressure in the through hole 32, which optimizes the device under test and improves the user experience.

[0041] The sensor mounting structure provided in this embodiment makes the sensor easy to install and remove and less likely to damage the sensor.

[0042] Specifically, please refer to Figure 1 The sensor mounting structure includes a first fixing component and a second fixing component. The first fixing component is detachably mounted on the test piece 3, and the sensor can be movably mounted on the first fixing component; the second fixing component is used to fix the sensor to the first fixing component. The first fixing component, the second fixing component, and the sensor are all separable from each other and applicable to the test piece 3; when removing the sensor, only the first fixing component and the second fixing component need to be removed. The disassembly and assembly steps are simple, highly flexible, and unlikely to damage the sensor, thus extending the sensor's service life.

[0043] The first fixing member is installed in the groove 31, and the sensor probe 1 is positioned facing the through hole 32. The first fixing member is detachably installed in the groove 31.

[0044] Furthermore, the first fixing member includes a sleeve 4 with threads on its outer side wall. The sleeve 4 can be fitted onto the sensor and screwed onto the test piece 3, ensuring good connection reliability. Specifically, the side wall of the groove 31 is threaded, and the sleeve 4 is screwed onto the side wall of the groove 31. In other embodiments, the sleeve 4 and the test piece 3 can also be connected in other ways, which are not limited here, as long as a detachable connection function can be achieved.

[0045] Preferably, the inner wall of the sleeve 4 is a smooth surface. The smooth surface can reduce the friction between the sleeve 4 and the sensor and protect the sensor from wear.

[0046] Specifically, the second fixing member includes a boss 11 disposed at the end of the probe 1 of the sensor. The outer diameter of the boss 11 is larger than the inner diameter of the sleeve 4. The end face of the sleeve 4 can abut against the boss 11 to fix the position of the sensor, so that the sensor does not detach from the test piece 3 and the installation stability is good.

[0047] Furthermore, the outer side wall of the end of the sleeve 4 that is screwed to the test piece 3 is provided with a recess 41 along the circumferential direction; the recess 41 facilitates the assembly and disassembly of the sleeve 4, making it easy for the sleeve 4 to extend into and exit the groove 31 on the test piece 3.

[0048] Preferably, the first fixing component is made of metal, which is less likely to damage the sensor and has a low cost.

[0049] Example 2

[0050] like Figure 2 As shown, this embodiment provides a sensor mounting structure. Unlike the first embodiment, the second fixing member provided in this embodiment includes a convex ring 5. The outer diameter of the convex ring 5 is larger than the inner diameter of the sleeve 4. When the sensor passes through the sleeve 4, the convex ring 5 is installed at the end of the sensor probe 1 so that the sensor does not detach from the sleeve 4.

[0051] Furthermore, the connection between the convex ring 5 and the sensor is a threaded connection, which ensures good connection reliability. In other embodiments, the convex ring 5 can also be connected to the sensor probe 1 in other ways; this is not limited here, as long as it achieves the function of fixed connection.

[0052] The other structures of the sensor mounting structure provided in this embodiment are the same as those in Embodiment 1, and will not be described in detail here.

[0053] The device under test provided in this embodiment includes a test piece 3 and a sensor mounting structure as described above disposed on the test piece 3. The connection method between the sensor mounting structure and the test piece 3 in this embodiment is the same as in Embodiment 1, and will not be described in detail here.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
