[0023] See Figures 1 to 3The figure shows a novel temperature sensor for railway signal cables, including a sensor base 11, a mounting shell 12, a first sensor 13, and a first snap-fit ​​component. The bottom of the sensor base 11 is mounted on the outer ring surface of the railway signal cable, and the right end of the inner wall of the sensor base 11 is fitted onto the outer ring surface of the mounting shell 12. The first sensor 13 and the sensor base 11 are respectively provided with the first snap-fit ​​component, and the first sensor 13 is coaxially snapped to the inner wall of the left end of the sensor base 11 through the first snap-fit ​​component.

[0024] In this invention, a first sensor 13 is provided at one end of the inner wall of the sensor base 11, and a mounting shell 12 and a second sensor 14 are sequentially inserted into the other end of the inner wall of the sensor base 11. Both the first sensor 13 and the second sensor 14 can be detached or installed. The two ends are used together and can be selected for single-sided detection or double-sided detection depending on the site conditions.

[0025] In this preferred embodiment, see Figures 2 to 3 The first locking component includes a first locking block 31, a first retaining ring 32, a first guide groove 33, and a first locking slot 34. The first locking block 31 is radially disposed in the middle of the outer ring surface of the first sensor 13, and the first retaining ring 32 is radially disposed at one end of the inner ring surface of the sensor base 11. The first guide groove 33 is axially disposed at one end of the inner ring surface of the sensor base 11, and the first locking slot 34 is radially disposed on the inner wall of the sensor base 11 at the first retaining ring 32, and the first locking slot 34 communicates with the first guide groove 33. The first sensor 13 is inserted into one end of the sensor base 11, and the first locking block 31 is slidably inserted into the first guide groove 33. When the first sensor 13 rotates, the first locking block 31 rotates and locks into the first locking slot 34.

[0026] Furthermore, the second locking component includes a second locking block 35, a second retaining ring 36, a second guide groove 37, and a second locking slot 38. The second locking block 35 is radially disposed in the middle of the outer ring surface of the second sensor 14, and the second retaining ring 36 is radially disposed at the other end of the inner ring surface of the mounting housing 12.

The second sensor 14 is inserted into one end of the mounting housing 12, and the second locking block 35 is slidably inserted into the second guide groove 37. When the second sensor 14 rotates, the second locking block 35 rotates and locks into the second locking slot 38.

[0027] Furthermore, the longitudinal cross-sections of the first sensor 13 and the second sensor 14 are T-shaped, and sensor leads 15 are respectively provided on the inner end faces of the T-shapes of the first sensor 13 and the second sensor 14. Specifically, the shapes of the first slot 34 and the second slot 38 are arc-shaped.

[0028] Both the first and second snap-fit ​​components have axial guide grooves on their inner ring surfaces and radial slots at the ends of the guide grooves and the retaining rings. The snap-fit ​​blocks are inserted along the guide grooves to the bottom and rotated into the slots for fixation, locking the snap-fit ​​blocks on the sensor protrusions to the housing. The first sensor 13 is securely installed inside the sensor base 11, and the second sensor 14 is securely installed inside the mounting housing 12, ensuring the sensors' horizontality and more accurate data detection. Installation is more convenient, and the installation direction can be determined during use, allowing for quicker and easier glue application.

[0029] In this preferred embodiment, see Figures 1 to 3 The temperature sensor also includes a distance adjustment assembly, which includes a slide groove 23 and a pair of sliders 24. The slide groove is located on one side of the outer ring surface of the sensor base 11, and the pair of sliders 24 are axially symmetrically located on one side of the outer ring surface of the mounting shell. The pair of sliders 24 are slidably disposed in the slide groove 23.

[0030] Furthermore, the distance adjustment assembly includes a fixing hole 25 and a screw. The fixing hole 25 is provided through the middle of the sensor seat 11 on the other side of the slide groove 23. The screw is inserted into the fixing hole 25 and abuts against the mounting shell 12.

[0031] The slide groove 23 of the sensor base 11 has a U-shaped longitudinal section. The left end of the mounting shell 12 is provided with a U-shaped groove, which can be inserted to adjust the distance between the first sensor 13 and the second sensor 14 on both sides, so as to facilitate observation of the internal situation. The screw is inserted into the fixing hole 25 to fix the position of the sensor base 11 and the mounting shell 12 on the other side, ensuring that the distance between the two sides will not change and preventing movement during detection.

[0032] In this preferred embodiment, a pair of first spacers 21 are axially arranged on the end face of the first sensor 13 side of the sensor base 11, and a pair of second spacers 22 are axially arranged on the end face of the second sensor 14 side of the mounting shell 12. The lengths of the first spacers 21 and the second spacers 22 are 5mm.

[0033] The purpose of the above-mentioned spacer block is to ensure that the distance between the sensor and the object being measured is 5mm.

[0034] In this preferred embodiment, the bottom of the sensor base 11 is provided with a pair of mounting holes 16 along the width direction, and the pair of mounting holes 16 are used to install on the outer ring surface of the telecommunications cable.

[0035] The temperature sensor is installed by securing it to the cable with cable ties through two long mounting holes 16.

[0036] In summary, this utility model provides a novel temperature sensor housing structure for railway signal cables. Firstly, the locking block and guide groove allow for better confirmation of the sensor orientation during installation, effectively avoiding the drawback of requiring separate confirmation of the sensor orientation in traditional technologies and improving work efficiency.

[0037] Secondly, an arc-shaped slot is designed on the outer shell structure, which allows the sensor to be rotated after reaching the bottom to lock the sensor protrusion block and the outer shell, making the potting process more convenient and simple, effectively avoiding waste of adhesive, and thus reducing working time.

[0038] Finally, the left and right housings (sensor base 11 and mounting housing 12) are used together, and single-sided or double-sided detection can be selected according to the site conditions. The detection distance can be adjusted by the pre-cut grooves 23 and sliders 24 on the housings. The housings are fixed with screws through holes to ensure that the distance between the two sides does not change, thereby making the measurement more accurate and improving the accuracy level.
