Description

Technical Field

[0001] The present invention relates to the technical field of sensor connectors, and in particular to a pressure sensor connector. Background Art

[0002] Sensor connectors are mainly used in conjunction with sensor cables and switch cables in a variety of different industrial applications. Sensor connectors are very versatile connectors that are usually available in a variety of different materials, sizes, and lengths to accommodate a variety of industrial components and applications. Sensor connectors are used to connect sensing devices and components, such as proximity sensors, photoelectric sensors, ultrasonic sensors, and current sensors, providing durable and secure connections. A pressure sensor connector is a device used to connect pressure sensors, which usually includes a plug and a socket. The plug is used to connect to the output of the pressure sensor, while the socket is used to connect to other devices or systems. The main function of the pressure sensor connector is to convert the analog signal of the pressure sensor into a digital signal for processing and analysis on a computer or other device.

[0003] In the prior art, since the application environment of pressure sensors includes industrial automation, environmental water treatment and other fields, for example, in an environment with liquid (such as water treatment, etc.), there may be humid water vapor in this environment, and water vapor may enter the gap between the pressure sensor and the pressure sensor connector after they are connected. As a result, the connection between the pressure sensor and the pressure sensor connector may be affected by moisture, causing corrosion of the internal metal parts. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a pressure sensor connector, which solves the problem that the application environment of the pressure sensor includes industrial automation, environmental water treatment and other fields. For example, in an environment with liquid (such as water treatment, etc.), there may be humid water vapor in this environment, and water vapor may enter the gap between the pressure sensor and the pressure sensor connector after they are connected. As a result, the connection between the pressure sensor and the pressure sensor connector may become damp, causing corrosion of the internal metal parts.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A pressure sensor connector, comprising a pressure sensor body, a sensor connector body is arranged on one side of the pressure sensor body, a protective shell is movably sleeved between the pressure sensor body and the sensor connector body, a mounting frame is movably sleeved inside the protective shell, a limiting hole is arranged on one side of the protective shell, and the limiting hole is movably sleeved with the pressure sensor body; a dustproof mechanism for reducing dust is arranged inside the protective shell; a moisture-proof component is arranged on the top and bottom surfaces of the interior of the mounting frame, and is used to moisture-proof the connection between the pressure sensor body and the sensor connector body, and the moisture-proof component comprises: two slide grooves, the two slide grooves are respectively arranged on the The inner top surface and bottom surface of the installation frame are respectively provided with operating grooves, the operating groove is connected with the slide groove, the inner sides of the operating groove are respectively provided with movable grooves, the inner part of the movable groove is movably sleeved with a clamping block, a spring is fixedly installed on one side of the inner part of the movable groove, the spring is fixedly installed with the clamping block, the top surface and bottom surface of the sensor connector body are respectively fixedly installed with sliding columns, a clamping hole is provided on one side of the sliding column, the sliding column is movably sleeved with the slide groove, the clamping block is movably sleeved with the clamping hole, a sealing groove is provided on one side of the sensor connector body, and the inner circular wall of the sealing groove is movably sleeved with a water-absorbing cotton ring.

[0007] By adopting the above technical solution and the provided absorbent cotton ring, when the staff installs and connects the pressure sensor body and the sensor connector body, they first put the pressure sensor body into the inside of the protective shell from the square position of the protective shell, and then let the pressure sensor body pass through the inside of the limiting hole. Due to the obstruction at the top of the protective shell, the pressure sensor body cannot completely pass through the limiting hole. When the protective shell moves to the rear end connection of the pressure sensor body, it will be blocked, so that the connection at the rear end of the pressure sensor body can be put inside the protective shell. At this time, the staff drives the sliding column and the absorbent cotton ring to move by moving the sensor connector body, so that the sensor connector body can be moved from the square rear end of the protective shell. Enter the interior of the protective shell, and then the pressure sensor body and the sensor connector body can be brought close to each other inside the protective shell, and then the pressure sensor body and the sensor connector body can be connected together. When the pressure sensor body and the sensor connector body are connected, the two will be close to each other. Since the water-absorbing cotton ring extends a short distance out of the sealing groove, the water-absorbing cotton ring will first be tightly attached to the surface of the pressure sensor body when the sensor connector body is close to the pressure sensor body. When the pressure sensor body and the sensor connector body are connected, the water-absorbing cotton ring will surround the connecting pins and sockets of the pressure sensor body and the sensor connector body, and then be used in conjunction with the protective shell, thereby reducing the pressure sensor body and the sensor connector body. The gap at the connection of the pressure sensor connector body is exposed. When the pressure sensor body and the sensor connector body are installed in a humid and vapor-heavy environment, such as close to a water source or during the rainy season, the absorbent cotton ring can absorb the moisture entering between the pressure sensor body and the sensor connector body, reduce the moisture entering the connection between the pressure sensor body and the sensor connector body, and prevent excessive moisture from entering between the pressure sensor body and the sensor connector body to affect the connection between the pressure sensor body and the sensor connector body. When the sensor connector body enters the interior of the protective shell and connects with the pressure sensor body, the sliding column will enter the interior of the operating slot through the sliding groove. At this time, by squeezing the sliding column into the two card blocks When the two clamping blocks are squeezed by the sliding column, the spring will be compressed and moved toward the inside of the moving groove, so that the two clamping blocks can move away from each other. Then the sliding column continues to move. When the position of the clamping hole and the clamping block coincides, the rebound of the spring will drive the clamping block to rebound, so that the two clamping blocks can be close to each other and enter the inside of the clamping hole, so as to limit the sliding column inside the operating groove, thereby facilitating the connection of the pressure sensor body, the sensor connector body and the protective shell together. The protective shell cooperates with the connection between the pressure sensor body and the sensor connector body to prevent the pressure sensor body and the sensor connector body from falling off after connection, thereby increasing the tightness of the connection between the pressure sensor body and the sensor connector body.

[0009] By adopting the above technical scheme, through the dust-proof gauze set, the pressure sensor body will pass through the inside of the dust-proof gauze when entering the interior of the protective shell, and the surface of the sensor connector body will contact the dust-proof gauze and a support ring when entering the interior of the protective shell, and push the dust-proof gauze and the support ring to move toward the interior of the protective shell and pull the elastic rope. When the pressure sensor body and the sensor connector body are connected, one end of the dust-proof gauze and a support ring will be close to one end of the interior of the protective shell, and the other end of the dust-proof gauze and the other support ring will be close to the surface of the sensor connector body. At this time, the state of the dust-proof gauze is to wrap the absorbent cotton ring, which can reduce the dust from entering the connection between the pressure sensor body and the sensor connector body and adhering to the surface of the absorbent cotton ring, and prevent a large amount of dust from falling on the surface of the absorbent cotton ring, resulting in a reduction in the moisture absorption effect of the absorbent cotton ring. Since the connection of the dust-proof gauze inside the protective shell is detachable in the protective shell through the second removable double-sided tape and the first removable double-sided tape, when the pressure sensor body and the sensor connector body are separated, it is convenient for the staff to disassemble and clean the dust-proof gauze.

At this time, the rotating block is away from the inside of the rotating groove, and then the staff rotates the rotating block to move the connecting column inside the spiral groove, and then the connecting column rotates and moves along the trajectory of the spiral groove, so that the two connecting columns can gradually move away from each other. At this time, the connecting column will drive the compression spring of the clamping block to move, and the clamping block can be put into the movable groove and the two clamping blocks can be moved out of the clamping hole, so that the restriction on the sensor connector body can be released, which is convenient for disassembly and separation of the pressure sensor body, the sensor connector body and the protective shell.

Due to the obstruction at the top of the protective shell 3, the pressure sensor body 1 cannot completely pass through the limiting hole 28. When the protective shell 3 moves to the plug-in position at the tail end of the pressure sensor body 1, it will be blocked, so that the plug-in position at the tail end of the pressure sensor body 1 can be sleeved inside the protective shell 3. At this time, the staff drives the sliding column 24 and the absorbent cotton ring 27 to move by moving the sensor connector body 2, so that the sensor connector body 2 can enter the inside of the protective shell 3 from the square tail end of the protective shell 3, and then the pressure sensor body 1 and the sensor connector body can be inserted into the protective shell 3.

Since the water-absorbing cotton ring 27 extends a short distance from the sealing groove 26, when the sensor connector body 2 is close to the pressure sensor body 1, the water-absorbing cotton ring 27 will first be in close contact with the surface of the pressure sensor body 1.

The protective shell 3 cooperates with the connection between the pressure sensor body 1 and the sensor connector body 2 to prevent the pressure sensor body 1 and the sensor connector body 2 from falling off after connection, thereby increasing the tightness of the connection between the pressure sensor body 1 and the sensor connector body 2.

[0042] Working principle: Please refer to Figure 1-Figure 10As shown, by the provided absorbent cotton ring 27, when the staff installs and connects the pressure sensor body 1 and the sensor connector body 2, firstly, the pressure sensor body 1 is placed into the inside of the protective shell 3 from the square position of the protective shell 3, and then the pressure sensor body 1 is allowed to pass through the inside of the limiting hole 28. Due to the obstruction at the top of the protective shell 3, the pressure sensor body 1 cannot completely pass through the limiting hole 28. When the protective shell 3 moves to the rear end of the pressure sensor body 1, it will be blocked, so that the rear end of the pressure sensor body 1 can be sleeved inside the protective shell 3. At this time, the staff drives the sliding column 24 and the absorbent cotton ring 27 to move by moving the sensor connector body 2, so that the sensor connector body 2 can be moved from the square position of the protective shell 3. The tail end of the pressure sensor enters the interior of the protective shell 3, so that the pressure sensor body 1 and the sensor connector body 2 can be close to each other inside the protective shell 3, and then the pressure sensor body 1 and the sensor connector body 2 can be connected together. When the pressure sensor body 1 and the sensor connector body 2 are connected, the two will be close to each other. Since the water-absorbing cotton ring 27 extends a short distance out of the sealing groove 26, when the sensor connector body 2 is close to the pressure sensor body 1, the water-absorbing cotton ring 27 will first be tightly attached to the surface of the pressure sensor body 1. When the pressure sensor body 1 and the sensor connector body 2 are connected, the water-absorbing cotton ring 27 will surround the connecting pins and sockets of the pressure sensor body 1 and the sensor connector body 2, and then cooperate with the protective shell 3 to be used, so that In order to reduce the exposure of the gap at the connection between the pressure sensor body 1 and the sensor connector body 2, when the pressure sensor body 1 and the sensor connector body 2 are installed in a humid and water-rich environment, such as: close to a water source or during the rainy season, the absorbent cotton ring 27 can absorb the water vapor entering between the pressure sensor body 1 and the sensor connector body 2, reduce the entry of humid water vapor into the connection between the pressure sensor body 1 and the sensor connector body 2, and prevent excessive humid water vapor from entering between the pressure sensor body 1 and the sensor connector body 2, causing corrosion of internal metal parts. When the sensor connector body 2 enters the interior of the protective shell 3 and is connected to the pressure sensor body 1, the sliding column 24 will enter the interior of the operating slot 6 through the slide groove 5. At this time, by letting The sliding column 24 is squeezed into between the two clamping blocks 8. After being squeezed by the sliding column 24, the two clamping blocks 8 will compress the spring 9 and move toward the inside of the moving groove 7, so that the two clamping blocks 8 can move away from each other. Then the sliding column 24 continues to move. When the position of the clamping hole 25 coincides with the position of the clamping block 8, the rebound of the spring 9 will drive the clamping block 8 to rebound, so that the two clamping blocks 8 can be close to each other and enter the inside of the clamping hole 25, so as to limit the sliding column 24 inside the operating groove 6, thereby facilitating the connection of the pressure sensor body 1, the sensor connector body 2 and the protective shell 3 together. The protective shell 3 cooperates with the connection of the pressure sensor body 1 and the sensor connector body 2 to prevent the pressure sensor body 1 and the sensor connector body 2 from falling off after connection.Increase the tightness of the connection between the pressure sensor body 1 and the sensor connector body 2.

[0043] Through the dust-proof gauze 29, when the pressure sensor body 1 enters the interior of the protective shell 3, it will pass through the interior of the dust-proof gauze 29. When the sensor connector body 2 enters the interior of the protective shell 3, its surface will contact the dust-proof gauze 29 and a support ring 30, and push the dust-proof gauze 29 and the support ring 30 to move toward the interior of the protective shell 3 and pull the elastic rope 31. When the pressure sensor body 1 and the sensor connector body 2 are connected, one end of the dust-proof gauze 29 and a support ring 30 will be close to one end of the interior of the protective shell 3, and the other end of the dust-proof gauze 29 and the other support ring 30 will be close to the sensor connector body 2. The surface is tightly attached. At this time, the dust-proof mesh 29 is in the state of wrapping the water-absorbing cotton ring 27, which can reduce the dust entering the connection between the pressure sensor body 1 and the sensor connector body 2 and adhere to the surface of the water-absorbing cotton ring 27 to prevent a large amount of dust from falling on the surface of the water-absorbing cotton ring 27, which causes the moisture absorption effect of the water-absorbing cotton ring 27 to be reduced. Since the dust-proof mesh 29 is connected inside the protective shell 3 through the second removable double-sided tape 33 and the first removable double-sided tape 32 and is detachable in the protective shell 3, when the pressure sensor body 1 and the sensor connector body 2 are separated, it is convenient for the staff to disassemble and clean the dust-proof mesh 29.

[0044] By setting the rotating block 18, when the staff separates the pressure sensor body 1 and the sensor connector body 2, when the staff pulls the rotating block 18 to drive the movable column 21, the limit block 22 and the limiting block 23 to move, the limit block 22 can be put into the limit groove 19 and the limiting block 23 can be moved out of the limiting groove 17. At this time, the rotating block 18 is away from the inside of the rotating groove 11, and then the staff rotates the rotating block 18 to move the connecting column 13 inside the spiral groove 20, and then the connecting column 13 rotates and moves along the trajectory of the spiral groove 20, so that the two connecting columns 13 can gradually move away from each other. At this time, the connecting column 13 will drive the clamping block 8 to compress the spring 9 to move, and the clamping block 8 can be put into the movable groove 7 and the two clamping blocks 8 can be moved out of the clamping hole 25, so that the restriction on the sensor connector body 2 can be released, which is convenient for disassembly and separation of the pressure sensor body 1, the sensor connector body 2 and the protective shell 3.
