Description

Technical Field

[0001] This utility model relates to a pressure sensor connector. Background Technology

[0002] Existing pressure sensor connectors consist of two parts: a first connector and a second connector that interlock. To prevent the connectors from detaching after connection, a limiting protrusion is provided on the outer side of the first connector along a direction perpendicular to the insertion direction, and a limiting latch is provided on the outer side of the second connector that can elastically deform along a direction perpendicular to the insertion direction. When the first and second connectors are connected, the limiting latch engages with the limiting protrusion, preventing the first and second connectors from separating on their own, thus avoiding the problem of pressure sensor connector detachment. The first connector has a first limiting part with its edge protruding outward along a direction perpendicular to the insertion direction, and the second connector has a second limiting part with its edge protruding outward along a direction perpendicular to the insertion direction and engaging with the first limiting part. The design of the first and second limiting parts enhances the stability of the connection between the first and second connectors and controls the insertion depth to achieve good contact. However, in actual use, especially for pressure sensor connectors used in aero engines, prolonged vibration can accelerate wear between the first and second connectors, easily leading to poor contact.

[0003] Chinese patent document CN218919448U discloses a connecting element for a sensor, including a sensor body and a device connector. One end of the sensor body is connected to a plug. A connecting mechanism is provided on the inner side of the outer wall of the plug. The plug is connected to the device connector via the connecting mechanism, with one end of the plug inserted into the interior of the device connector. A latching mechanism is provided on the outer side of the outer wall of the plug, engaging with the device connector. The connecting mechanism includes a positioning component, a connecting sleeve, and a connecting component. The positioning component is located on the inner side of the outer wall of the plug. The connecting sleeve is rotatably connected to the outer wall of the plug via the positioning component. The connecting component is located on the outer side of the inner wall of the connecting sleeve, connecting the connecting sleeve to the outer wall of the device connector via the connecting component. A control component is provided on the outer wall of the connecting sleeve, and the control component is drively connected to the latching mechanism. The beneficial effects of this existing technical solution are as follows: When connecting the sensor body to an external device, the plug is inserted into the device connector, and the connecting sleeve is fitted onto the outer wall of the device connector through the connecting component. The plug can be firmly secured inside the device connector through the connecting mechanism, and the plug can be secured to the inner wall of the device connector through the snap-fit ​​mechanism. This can achieve the effect of securing the plug and prevent the connecting mechanism from loosening due to vibration, bumps, or shaking, which would affect the connection position between the sensor body and the external device. This makes the position of the sensor body more stable and prevents the sensor body from falling off and affecting normal use. Furthermore, the locking rod can be separated from the locking slot through the control component, and then the plug can be separated from the device connector by rotating the connecting sleeve.

[0004] While this existing technology solves the problem of poor contact in sensor connectors under vibration, it suffers from a complex structure and requires significant modifications to the existing pressure sensor connector. Furthermore, the pressure sensor connectors used in aero engines are standard components, making structural adjustments impossible. Utility Model Content

[0005] The purpose of this invention is to provide a pressure sensor connector to solve the problem that pressure sensor connectors in the prior art are prone to poor contact under vibration.

[0006] To achieve the above objectives, the basic solution of this utility model provides a pressure sensor connector, including a first connector and a second connector that are mutually inserted and mated. The first connector has a first limiting portion with its edge protruding outward along a direction perpendicular to the insertion direction, and the second connector has a second limiting portion with its edge protruding outward along a direction perpendicular to the insertion direction and being inserted and mated with the first limiting portion. The connector also includes a snap-fit ​​member for pressing the first limiting portion and the second limiting portion together, wherein the snap-fit ​​member is snap-fitted and mated with the first connector and the second connector respectively.

[0007] The beneficial effects of this basic solution are as follows: by utilizing the original first and second limiting parts on the pressure sensor connector, and by setting a snap-fit ​​part to engage with the first and second connectors respectively, the first and second limiting parts are pressed together, thereby avoiding the phenomenon of the first and second connectors shaking along the insertion direction, and thus avoiding the problem of poor contact of the pressure sensor connector under vibration environment.

[0008] Preferably, the snap-fit ​​component has a first snap-fit ​​portion that snaps into the side of the first connector located away from the second limiting portion of the first connector, and a second snap-fit ​​portion that snaps into the side of the second connector located away from the first limiting portion of the second connector. A tie portion is fixedly connected between the first snap-fit ​​portion and the second snap-fit ​​portion. With this arrangement, the first snap-fit ​​portion and the second snap-fit ​​portion interact through the tie portion, so that when the first snap-fit ​​portion snaps into the first connector and the second snap-fit ​​portion snaps into the second connector, a force is generated between the first snap-fit ​​portion and the second snap-fit ​​portion through the tie portion, pressing the first limiting portion and the second limiting portion together. In this way, with a relatively simple snap-fit ​​component structure, the problem of poor contact between the first connector and the second connector can be avoided, which is beneficial to improving the reliability of the pressure sensor connector and reducing improvement costs.

[0009] Preferably, the first snap-fit ​​portion, the second snap-fit ​​portion, and the pull-tab portion are all plate-shaped. This arrangement helps to further reduce improvement costs.

[0010] Preferably, the first snap-fit ​​portion, the second snap-fit ​​portion, and the tie portion are integrally formed. This arrangement helps to further improve the reliability of the snap-fit ​​component and reduce production costs.

[0011] Preferably, the first snap-fit ​​portion is provided with a first snap-fit ​​groove that engages with the first connector, and the first snap-fit ​​portion is provided with a first connecting groove extending from the edge of the first snap-fit ​​groove to the tie portion; the second snap-fit ​​portion is provided with a second snap-fit ​​groove that engages with the second connector, and the second snap-fit ​​portion is provided with a second connecting groove extending from the edge of the second snap-fit ​​groove to the tie portion. With this configuration, the first snap-fit ​​groove of the first snap-fit ​​portion transmits the force to the tie portion during the snap-fit ​​operation, causing the plate-like structure of the tie portion to undergo bending elastic deformation, thereby changing the size of the first snap-fit ​​groove to facilitate the snap-fit ​​operation; similarly, the size of the second snap-fit ​​groove of the second snap-fit ​​portion is also adjusted through the elastic deformation of the tie portion. Therefore, this configuration makes the structure of the snap-fit ​​component simple and reliable, which is beneficial for further reducing the improvement cost of the pressure sensor connector.

[0012] Preferably, the snap-fit ​​connector is a stainless steel snap-fit ​​connector. This design utilizes the properties of stainless steel to give the snap-fit ​​connector both rigidity and elasticity, while also enhancing its durability. Attached Figure Description

[0017] The following detailed description illustrates the specific implementation method:

[0018] The reference numerals in the accompanying drawings include: first connector 1, first limiting part 11, second connector 2, second limiting part 21, snap-fit ​​part 3, first snap-fit ​​part 31, second snap-fit ​​part 32, tie part 33, first slot 311, and first connecting slot 312.

[0019] The basic implementation examples are as follows: Figures 1 to 4 As shown: A pressure sensor connector includes a first connector 1 and a second connector 2 that are mutually inserted and mated. The first connector 1 has a first limiting portion 11 whose edge protrudes outward along a direction perpendicular to the insertion direction, thus forming an enlarged portion with a large cross-sectional size on the first connector 1. The second connector 2 has a second limiting portion 21 whose edge protrudes outward along a direction perpendicular to the insertion direction and is inserted and mated with the first limiting portion 11, thus forming an enlarged portion with a large cross-sectional size on the second connector 2. When the first connector 1 and the second connector 2 are inserted and mated, the first limiting portion 11 also inserts and mated with the second limiting portion 21, thereby limiting the insertion depth between the first connector 1 and the second connector 2 through the insertion and mating of the first limiting portion 11 and the second limiting portion 21, and also enhancing the connection stability between the first connector 1 and the second connector 2. A snap-fit ​​member 3 is also connected between the first connector 1 and the second connector 2 to press the first limiting portion 11 and the second limiting portion 21 together, and the snap-fit ​​member 3 snaps and mated with the first connector 1 and the second connector 2 respectively.

[0020] In this embodiment, the snap-fit ​​component 3 has a first snap-fit ​​portion 31 that engages with the side of the first connector 1 located away from the second limiting portion 21 of the first limiting portion 11, and a second snap-fit ​​portion 32 that engages with the side of the second connector 2 located away from the first limiting portion 11 of the second limiting portion 21. A tie portion 33 is fixedly connected between the first snap-fit ​​portion 31 and the second snap-fit ​​portion 32. In this embodiment, the first snap-fit ​​portion 31, the second snap-fit ​​portion 32, and the tie portion 33 are all plate-shaped. Preferably, the first snap-fit ​​portion 31, the second snap-fit ​​portion 32, and the tie portion 33 are integrally formed. In this embodiment, the snap-fit ​​component 3 is a stainless steel snap-fit ​​component 3, so that the first snap-fit ​​portion 31, the second snap-fit ​​portion 32, and the tie portion 33 are all made of stainless steel plates, thereby giving the first snap-fit ​​portion 31, the second snap-fit ​​portion 32, and the tie portion 33 both a certain rigidity and a certain elasticity.

[0021] In this embodiment, the first snap-fit ​​portion 31 is provided with a first snap-fit ​​groove 311 that engages with the first connector 1, and the first snap-fit ​​portion 31 is provided with a first connecting groove 312 extending from the edge of the first snap-fit ​​groove 311 to the tie portion 33; the second snap-fit ​​portion 32 is provided with a second snap-fit ​​groove that engages with the second connector 2, and the second snap-fit ​​portion 32 is provided with a second connecting groove extending from the edge of the second snap-fit ​​groove to the tie portion 33.

[0022] The specific implementation process is as follows: After the first connector 1 and the second connector 2 are inserted into place, the first limiting part 11 and the second limiting part 21 are also in the insertion state. Then, the snap-fit ​​part 3 is snapped onto the first connector 1 with the first snap-fit ​​part 31 aligned with the side of the first limiting part 11 away from the second limiting part 21, so that the first connector 1 is snapped into the first slot 311; at the same time, the second snap-fit ​​part 32 is aligned with the side of the second limiting part 21 away from the first limiting part 11 and snapped onto the second connector 2, so that the second connector 2 is snapped into the second slot. When the snap-fit ​​part 3 is snapped onto the first connector 1 and the second connector 2, the snap-fit ​​part 3 will undergo a certain elastic deformation, thereby increasing the distance between the first snap-fit ​​part 31 and the second snap-fit ​​part 32. After the snap-fit ​​operation is completed, the first limiting part 11 and the second limiting part 21 are pressed together by the elastic force of the snap-fit ​​part 3, thereby preventing the first connector 1 and the second connector 2 from shaking along the insertion direction under vibration, and avoiding the problem of poor contact.

[0023] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics of the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
