Description

Technical Field

[0001] This application relates to the field of sensors, and more particularly to a speed sensor suitable for short-pin chips. Background Technology

[0002] Rotation speed sensors, as a key measuring device, are widely used in modern industry and mechanical equipment. Their core function is to convert the rotational speed of a rotating object into a measurable electrical signal output. This type of sensor belongs to indirect measuring devices and can measure rotational speed using various principles such as mechanics, electricity, magnetism, and optics. With the continuous advancement of technology, rotation speed sensors have achieved significant improvements in accuracy, stability, reliability, and applicability.

[0003] In practical applications of speed sensors, the stability of the connector has always been one of the key factors affecting the performance and reliability of the sensor. In existing technologies, although various methods have been adopted to fix the connector, under certain complex or harsh working conditions, the connector may still be at risk of falling off due to vibration, impact or long-term operation. Such falling off will not only cause the interruption of the sensor signal and affect the normal operation of the equipment, but may also cause more serious safety accidents. Utility Model Content

[0004] In order to solve

[0005] Under certain complex or harsh working conditions, the connector may still be at risk of falling off due to vibration, impact or loosening caused by long-term operation. This application provides a speed sensor suitable for short-pin chips.

[0006] This application provides a speed sensor suitable for short-pin chips, employing the following technical solution: It includes a speed sensor body and a chip. The chip is mounted on the chip mounting end of the speed sensor body. Pin bodies are symmetrically fixedly connected to the ends of the chip. The pin bodies are bent relative to the chip and contact the top edge of the speed sensor body. An electrode plate is provided at the top edge of the speed sensor body. The pin bodies are welded to the electrode plate. Connectors are symmetrically arranged at the access end of the speed sensor body. A cable for signal transmission is provided at the end of the connector. A pressing mechanism for limiting the position of the connector is provided on the outer wall of the speed sensor body.

[0007] By adopting the above technical solution and setting the pressing mechanism, this speed sensor achieves effective limiting and stabilization of the connector. During use, even when faced with vibration or external force interference, the pressing mechanism can ensure that the connector is firmly connected to the main body of the speed sensor, effectively preventing signal transmission interruption caused by loose or detached connector, thereby greatly improving the stability and reliability of the sensor.

[0008] Preferably, the outer side wall of the speed sensor body is provided with a bracket for support below the connector, and a fixing plate is fixedly connected to the outer side wall of the speed sensor body at the interval between the two brackets.

[0009] By adopting the above technical solution, the design of the bracket located below the connector provides a solid support foundation for the connector. This not only ensures the stability and accuracy of the connector during installation, but also effectively distributes the weight and stress borne by the connector, avoiding the problem of connector loosening or damage caused by long-term cable hanging. The setting of the fixing plate at the interval between the two brackets not only strengthens the structural strength of the speed sensor body, but also provides a stable installation platform for accessories such as the pressing mechanism.

[0010] Preferably, the pressing mechanism includes fixed brackets symmetrically fixedly connected to the top of the fixed plate, with a pressing frame rotatably sleeved inside the fixed bracket, and a limit spring fixedly connected between the two pressing frames.

[0011] By adopting the above technical solution, a stable connection is achieved between the two pressure brackets through the limit spring. The limit spring not only provides the necessary elasticity and reset function for the pressure bracket, but also ensures that the pressure bracket can apply pressure evenly and smoothly to the joint during the pressing process, effectively preventing joint damage or poor signal transmission caused by uneven pressure, and improving the stability and reliability of the sensor.

[0012] Preferably, a pressure plate is placed on the upper top of the two joints, a pressure groove is opened at the lower bottom of the pressure plate corresponding to the position of the joint, and an opening groove is opened through the upper top of the pressure plate, with the upper top of the two lower pressure frames passing through the opening groove and located above the pressure plate.

[0013] By adopting the above technical solution, the design of the pressure plate is a key part of the pressing mechanism. It acts directly on the top of the joint. Through the tight fit between the pressure groove and the joint, the joint is effectively limited and stabilized. The through slot at the top of the pressure plate provides space for the pressing frame to pass through, allowing the pressing frame to act directly on the pressure plate. Through the elastic force of the limiting spring, the pressure is evenly and stably transmitted to the joint. This not only improves the stability and reliability of the pressing mechanism, but also makes the pressure distribution more uniform, avoiding joint damage caused by excessive local pressure.

[0014] Preferably, the outer side wall of the fixing plate is symmetrically fixedly connected with a lifting plate for supporting the pressure plate, and the upper and lower ends of the fixing plate are both fixedly connected with triangular reinforcing strips, and the reinforcing strips are fixedly connected to the outer side wall of the speed sensor body.

[0015] By adopting the above technical solution, the introduction of the lifting plate provides additional support and bearing for the pressure plate, ensuring that the pressure plate can remain stable when subjected to the pressure of the lower pressure frame, and will not deform or shift due to uneven force. This not only enhances the overall stability and reliability of the lower pressure mechanism, but also allows the pressure to be applied more evenly to the joint, avoiding the problem of joint loosening or damage caused by pressure plate instability.

[0016] Preferably, the outer wall of the connector is provided with a circular groove, and the bottom end of the pressure plate is provided with an arc-shaped protrusion at the pressure groove.

[0017] By adopting the above technical solution, the design of the circular groove on the outer wall of the connector and the arc-shaped protrusion at the bottom of the pressure plate achieves precise matching and tight fit between the two.

[0018] Preferably, the end of the lower pressure frame is triangular, and the end of the lower pressure frame is symmetrically provided with through slots.

[0019] By adopting the above technical solution, the triangular design of the lower pressure frame end enhances its stability and guidance when pressure is applied. This not only allows the lower pressure frame to distribute pressure more evenly on the pressure plate, avoiding local damage caused by pressure concentration, but also improves the stability and accuracy of the lower pressure frame during rotation.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] This utility model features a pressing mechanism that presses down on the connector during use, effectively restricting its position and preventing it from detaching due to fluctuations. The pressure plate compresses the connector, while two pressing frames limit the pressure plate via limiting springs. Since the pressure plate presses down on the upper end of the connector, it ensures that the connector will not detach. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0028] This application discloses a speed sensor suitable for short-pin chips.

[0029] Reference Figure 1 and Figure 2 A speed sensor suitable for short-pin chips includes a speed sensor body 1 and a chip 4. The chip 4 is mounted on the chip mounting end of the speed sensor body 1. A pin body 41 is symmetrically fixedly connected to the end of the chip 4. The pin body 41 is bent and contacts the top end of the speed sensor body 1. An electrode plate 13 is provided at the top end of the speed sensor body 1. The pin body 41 is welded to the electrode plate 13. A connector 2 is symmetrically provided at the access end of the speed sensor body 1. A cable 21 for transmitting signals is provided at the end of the connector 2. A pressing mechanism 3 for limiting the connector 2 is provided on the outer wall of the speed sensor body 1.

[0030] Reference Figure 1 and Figure 3 The outer side wall of the speed sensor body 1 is provided with a bracket 11 for support below the connector 2, and a fixing plate 12 is fixedly connected to the outer side wall of the speed sensor body 1 at the interval between the two brackets 11.

[0031] Reference Figure 3 and Figure 4 The pressing mechanism 3 includes a fixed bracket 35 symmetrically fixedly connected to the top of the fixed plate 12. A pressing frame 36 is rotatably sleeved inside the fixed bracket 35. A limit spring 37 is fixedly connected between the two pressing frames 36. A pressure plate 31 is placed on the top of the two joints 2. A pressure groove 33 is opened at the bottom of the pressure plate 31 corresponding to the position of the joint 2. An opening groove 32 is opened through the top of the pressure plate 31. The top of the two pressing frames 36 passes through the opening groove 32 and is located above the pressure plate 31. A lifting plate 34 for supporting the pressure plate 31 is symmetrically fixedly connected to the outer wall of the fixed plate 12. Triangular reinforcing strips are fixedly connected to both the upper and lower ends of the fixed plate 12, and the reinforcing strips are fixedly connected to the outer wall of the speed sensor body 1.

[0032] Reference Figure 3and Figure 4 The outer wall of the connector 2 is provided with a circular groove, the bottom end of the pressure plate 31 is located at the pressure groove 33 and has an arc-shaped protrusion, the end of the lower pressure frame 36 is triangular and the end of the lower pressure frame 36 is symmetrically provided with through grooves.

[0033] The implementation principle of a speed sensor suitable for short-pin chips in this application embodiment is as follows: This utility model achieves effective fixation of the connector 2 by cleverly setting a pressing mechanism 3, thereby greatly improving the reliability and durability of the speed sensor. After the chip 4 is welded to the electrode plate 13 on the speed sensor body 1 through its bent pin body 41, the connector 2 is installed at the input end of the speed sensor body 1 as the signal transmission entrance. The fixing bracket 35 is fixedly connected to the fixing plate 12, providing a fulcrum for the rotation of the pressing frame 36. The pressing frame 36 can rotate freely inside the fixing bracket 35 and is connected to another pressing frame 36 through the limiting spring 37, forming a stable elastic structure. When the pressure plate 31 is pressed... When placed above the connector 2, the pressure groove 33 at its lower end can fit tightly against the outer wall of the connector 2. At this time, the upper tops of the two lower pressure brackets 36 pass through the opening slots 32 on the pressure plate 31, and due to the elastic force of the limiting spring 37, a downward pressure is generated on the pressure plate 31. This pressure is transmitted to the connector 2 through the pressure plate 31, thereby achieving a firm fixation of the connector 2. The lower end of the pressure plate 31 forms an arc-shaped protrusion at the position of the pressure groove 33, which matches the circular groove on the outer wall of the connector 2, further enhancing the fit and stability between the pressure plate and the connector. At the same time, the lifting plate 34 on the outer wall of the fixing plate 12 also provides an additional support point for the pressure plate 31, ensuring that the pressure plate 31 will not deform or shift when subjected to force.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
