Description

Technical Field

[0001] The present application relates to the technical field, and in particular to a side-outlet sensor housing and a side-outlet sensor. Background Art

[0002] Since the impact signal monitoring requires the overall rigidity of the sensor to be relatively high, most impact monitoring sensors use straight-out lines, and the components are hard-connected. However, in order to better collect vibration, impact and temperature signals at various fault-prone locations, composite sensors used in machinery, ships, rail transit and other fields should be installed as close to the fault-prone area as possible. However, due to structural limitations and limited height space, some measuring points cannot use straight-out line sensors.

[0003] The commonly used solution at present is to use a tail bend for side outlet. Since all components are hard-connected and the installation interface is threaded, it is impossible to locate the outlet direction and it needs to be adjusted with gaskets. The installation is cumbersome and requires multiple disassembly and assembly.

[0004] Another way is to use a slip ring. A gap is left between the tail cable sealing and locking structure and the base, allowing unlimited relative rotation. This solution solves the direction problem, but due to the existence of the gap, the impact signal monitoring effect is poor and the failure rate is high.

[0005] In summary, how to provide a structure that can be installed in a location with limited height space, locate the direction of the outgoing line, and ensure the impact signal monitoring effect is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0019] Preferably, it further comprises a sensitive component, which comprises a circuit board, a shock sensitive element and a temperature sensitive element. The shock sensitive element is mounted on the circuit board, and the temperature sensitive element is located in the probe and electrically connected to the circuit board.

At the same time, in order to improve the resonant frequency of the sensor and ensure the reliability of the sensor signal, arc chamfers and multiple avoidance grooves are designed to avoid space and interference signals. At the same time, asymmetric designs are adopted on the left and right sides to limit the optimal inclination range of the side walls of the base to optimize the structural resonance performance of the sensor, ultimately improving the resonance and ensuring the signal strength. However, the asymmetric design results in the direction of the base being fixed when avoiding space, and the arc surface can only be close to a limited position in the space, so the installation direction of the sensor is fixed, but the tail line of the sensor can only point to an open area to facilitate wiring. Therefore, symmetrical wire insertion holes are designed on the front and back sides of the base for optional cable outlet directions, so that the cable can be selected to be front or rear outlet during assembly to meet the needs of different installation environments.

In this embodiment, the sensitive component includes a circuit board 21, an impact sensitive element (not shown), and a temperature sensitive element 23.

[0040] The housing 1 is used to accommodate the sensitive component and allow the cable 3 to be inserted from the side to connect the sensitive component.

This can effectively reduce the vertical height when the housing is installed at an angle (such as Figure 6 As shown), the requirements of different installation environments are met. In this embodiment, the arc chamfer is concentric with the jack, so that the arc chamfer can obtain the maximum curvature and the vertical height during tilted installation is minimized. Of course, in other embodiments, the arc chamfer 13 and the jack 11 may be concentric or not concentric according to requirements.

[0041] In this embodiment, both the front and rear sides of the housing 1 are provided with jacks 11 for inserting the cable 3, so that the outlet direction of the cable 3 is optional, so that the cable 3 can be optionally outlet from the front during assembly (such as Figure 3 as shown) or later (as shown Figure 4 to meet the needs of different installation environments (the sensor tail line can only be easily routed if it points to an open area).

[0042] In this embodiment, the housing 1 includes a base 14, a side cover 15, an upper cover 16, and a probe 17. Figure 7 As shown, the above-mentioned jack 11, fixing portion 12, and arc chamfer 13 are all located on the base 14. The fixing portion 12 includes protrusions 121 extending from the base body to the left and right sides, and each protrusion is provided with a fixing through hole 122, so that the base 14 can be installed on the test piece by screws.

[0043] The side cover 15 is used to cooperate with the jack 11 and is welded to the base 14 to seal the side of the base 14. The probe 17 is used to place the temperature sensitive element 23 in the sensitive component. The upper cover 16 is used to clamp and fix the circuit board 21 in the sensitive component.

Of course, in other embodiments, the upper cover can also adopt other structures to clamp and fix the circuit board.

[0044] Both the front and rear sides of the base 14 are provided with jacks 11 for inserting the cable 3, one of the jacks 11 is for the cable 3 to be inserted and tightly connected, and the side cover 15 cooperates with the other jack 11 and is welded to the base 14 to seal the side of the base 14. The top surface of the base 14 is provided with an upper opening 141, and the upper cover 16 cooperates with the upper opening 141 and is welded to the base 14 to seal the top of the base 14. The bottom surface of the base 14 is provided with a lower through hole 142, and the probe 17 cooperates with the lower through hole 142 and is welded to the base 14 to seal the bottom of the base 14. The shape of the side cover 15 is adapted to the jack 11, and can also be circular. The side opposite to the arc chamfer 13 of the left and right sides of the base 14 is an inclined surface from the top to the fixing part 12, and the left and right sides are provided with avoidance grooves 143 to avoid the screws of the installation part.

[0045] In this embodiment, Figure 5 As shown, the angle Φ1 between the upper surface of the base fixing portion 12 and the side wall of the base 14 with the circular chamfer 13 is in the range of 120° to 130°; the angle Φ2 between the upper surface of the base fixing portion 12 and the side wall of the base 14 without the circular chamfer 13 is in the range of 105° to 115°. Tests have shown that the above inclination angle range can optimize the structural resonance performance of the sensor, ultimately improve the resonance, and ensure the signal strength.

[0046] The circuit board 21 is mounted on the base 14 through the upper cover 16, and is located on the side away from the arc chamfer 13. In this way, the circuit board 21 is arranged in parallel with the cable 3, making the structure compact and reducing the volume of the side-outlet sensor. The impact sensitive element is mounted on the circuit board 21, and a MEMS (Micro Electro-Mechanical Systems) chip or other electronic components sensitive to impact can be used. A metal shielding member 22 covering the impact sensitive element is also mounted on the circuit board 21. The temperature sensitive element 23 is located in the probe 17 and is electrically connected to the circuit board 21 through the wire 24. A PT100 platinum resistor or other electronic components sensitive to temperature can be used. In addition, in this embodiment, a plurality of grooves 211 are provided at the bottom of the circuit board 21, and the base 14 is filled with epoxy glue, and the epoxy glue can enter the grooves 211 to prevent the components in the base 14 from loosening, ensure the integrity of the structure, and effectively improve the pressure resistance of the sensor. Of course, in other embodiments, the sensitive component may not be provided with a circuit board, an impact sensitive element, or a temperature sensitive element, but may include other sensitive elements and related elements.
