Description

Technical Field

[0001] This utility model relates to the field of pressure gauges, and in particular to an electrical contact signal connection device for pressure gauges. Background Technology

[0002] In modern industry, pressure measurement is a crucial aspect of ensuring the safe and efficient operation of equipment. Traditional pressure gauges typically employ a mechanical structure to measure pressure and display the pressure value via a pointer. However, mechanical pressure gauges often suffer from insufficient response speed and sensitivity in high-frequency and rapidly changing pressure environments, leading to reduced measurement accuracy. Furthermore, wear and aging of the mechanical structure can also affect its long-term stability and reliability.

[0003] To overcome these shortcomings, electrical contact pressure gauges have gradually become widely used. Electrical contact pressure gauges measure pressure through electrical signal transmission, offering advantages such as fast response, high accuracy, and ease of remote monitoring. However, existing electrical contact signal connection devices still have some design deficiencies. For example, poor contact between connecting components can lead to unstable signal transmission, affecting the accuracy of measurement results; simultaneously, the complexity of the device's structure makes maintenance and replacement difficult.

[0004] Therefore, an electrical contact signal connection device for pressure gauges is proposed to solve the above problems. Utility Model Content

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An electrical contact signal connection device for a pressure gauge includes a contact switching base, on which a plurality of insulating pads are sequentially arranged: The insulating pads include insulating pad A, insulating pad B, insulating pad C and a top insulating pad. The insulating pads are stacked to ensure effective isolation between the electrical parts and the metal parts. The top of the insulating pads is covered with a cover plate to prevent external contamination or damage. The switching base is equipped with a left wire conductive pin component and a right wire conductive pin component. Both the left-side conductive pin component and the right-side conductive pin component are equipped with a short-setting conductive pin component and a long-setting conductive pin component. A bent pointer component is also disposed above the left-hand conductive pin component.

[0007] Furthermore, the left and right conductive pin components are respectively located on both sides of the switching base and connected to the bottom of insulating pad A, insulating pad B and insulating pad C.

[0008] Furthermore, the left and right conductive pin components are arranged in a mirror image. Each component includes a conductive plate, a pin shaft is positioned above the conductive plate, a pin seat is fixedly connected below the pin shaft, a jewel bearing is positioned below the pin seat, a movable conductive pin is connected below the jewel bearing, a grooved hairspring is connected to and in contact with the side of the movable conductive pin, an open retaining ring is positioned on the other side of the grooved hairspring and fixed to the pin seat by the open retaining ring, a conductive shaft washer is positioned at the bottom of the pin seat, a flat wire is connected to the side of the conductive shaft washer, and a contact point is positioned below the conductive shaft washer.

[0009] Furthermore, the short setting conductive needle component and the long setting conductive needle component are respectively located below the insulating pad C and are fixedly connected to the switching base via positioning posts; wherein, the short setting conductive needle component includes a short setting conductive needle, a fixed conductive plate is fixedly connected below the short setting conductive needle, a set shaft is provided at the center of the fixed conductive plate, a set shaft washer and a spring washer are respectively provided on both sides of the set shaft, a magnet sleeve is provided below the set shaft, a magnet is embedded in the magnet sleeve, and a second contact is connected below the magnet.

[0010] Furthermore, the bent pointer component is positioned above the left-hand conductive pin component; wherein, the bent pointer component includes a bent pointer, a pointer push rod is connected below the bent pointer, the front end of the pointer push rod passes through the base and is connected to a cross-head self-tapping screw, the end of the cross-head self-tapping screw is connected to a pin cap, and a counterweight is connected to the other side of the pin cap.

[0011] Furthermore, the bottom of the switching base is provided with a cross-slot countersunk screw and an I-type hexagonal nut.

[0012] In summary, this utility model has the following beneficial effects: Through precise mechanical structure design, the detection sensitivity and response speed of pressure changes are significantly improved. The efficient contact mechanism between the moving conductive needle and the contact point ensures that an electrical signal can be generated rapidly when the pressure increases, thereby achieving real-time monitoring. This rapid response capability enables the device to operate effectively in dynamically changing working environments, meeting the high precision and high reliability requirements of industrial applications. The left and right conductive needle components are connected by an insulating pad at the bottom, further enhancing electrical isolation and contact stability, effectively preventing signal distortion caused by excessive movement. Equipped with short and long setting conductive needle components, these setting components ensure precise adjustment and accurate signal transmission of the device. At the same time, the curved pointer component positioned above the left conductive needle component effectively enhances the balance and flexibility of the indicating system.

[0013] By symmetrically arranging the left and right conductive pin components in a mirror manner, and combining them with components such as the conductive plate, pin shaft, pin seat, and jewel bearing, more stable and precise electrical contact control is achieved. The side of the conductive pin is connected and fixed to the grooved hairspring, ensuring the stability and flexibility of the conductive pin. The conductive shaft washer and the contact settings further improve the contact conduction efficiency. The cooperation between the short setting conductive pin component and the long setting conductive pin component with the magnet sleeve and the second contact enhances the signal accuracy and adjustability of the device.
