Description

Technical Field

[0001] This utility model relates to a protective device, and more particularly to a connector protective device for a single-crystal silicon pressure sensor. Background Technology

[0002] For existing single-crystal silicon pressure sensors, the connectors used for data transmission and the terminals extending from them are all exposed. When used for pressure sensing tests in liquid environments, the terminals and connectors may be splashed or soaked by liquid, easily causing abnormal short circuits. Currently, this interface layout is often treated with resin potting. However, this does not allow the sensor to move; that is, if it is moved again after installation, the terminals may be pulled and break.

[0003] Alternatively, a plastic tube can be fitted over the connector. However, due to different installation locations, the spacing between the connector points varies, requiring experienced installers to cut the plastic tube precisely. Improper cutting can still allow liquid to seep in. Excessive clearance can also push the sensor upwards, causing instability during installation.

[0004] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a connector protection device for monocrystalline silicon pressure sensors, making it more valuable for industrial applications. Utility Model Content

[0034] 11 Antistatic coating Detailed Implementation

[0035] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0036] like Figures 1 to 5The connector protection device for a single-crystal silicon pressure sensor includes a docking inner tube 1, which is unique in that an extended outer tube 2 is movably connected to the outside of the docking inner tube 1. The total length between the docking inner tube and the extended outer tube 2 can be controlled by adjusting the position of the extended outer tube 2, effectively preventing water splashing from the connector and its connecting terminals. Simultaneously, several guide grooves 3 are distributed on the inner wall of the extended outer tube 2, and guide blocks 4 are distributed at corresponding positions on the outer wall of the docking inner tube, embedded in the guide grooves 3. This provides appropriate guidance for the movement of the extended outer tube 2. Furthermore, the matching of the guide blocks 4 and the guide grooves 3 prevents accidental separation of the extended outer tube 2. During implementation, several positioning components are distributed at the upper end of the docking inner tube 1, which can mate with the outer ring of the lower connector terminal of the single-crystal silicon pressure sensor, smoothly connecting this invention to the single-crystal silicon pressure sensor. Moreover, to appropriately fill the lower gap at the installation position, a covering component 5 is distributed at the lower end of the extended outer tube 2.

[0037] In a preferred embodiment of this invention, the guide groove 3 is a longitudinally distributed rectangular groove, and the guide block 4 is a rectangular block with several friction contact grooves distributed on its surface. This allows the guide block 4 and guide groove 3 to have appropriate contact damping through the compression deformation of the friction contact grooves, preventing easy slippage or loosening after being positioned, thus facilitating the maintenance of the final set length over a long period. For single-crystal silicon pressure sensors with smaller connectors, the guide groove 3 is a longitudinally distributed arc groove 6, and the guide block 4 is an arc protrusion 7. This allows for appropriate mating damping when the inner tube 1 and the extended outer tube 2 have relatively small inner diameters. Furthermore, the upper and lower ends of the extended outer tube 2 are fitted with blocking rings 10, the width of which is greater than the depth of the guide groove 3. This limits the end position of the guide block 4, further preventing it from loosening from the guide groove 3.

[0038] Furthermore, the positioning component used in this invention consists of several double-sided adhesive patches 8 attached to the upper end of the inner tube 1, facilitating convenient bonding. Of course, for full-coverage bonding, double-sided adhesive rings can also be used. For single-crystal silicon pressure sensors with larger interfaces, the positioning component consists of several clips 9 distributed on the upper end of the inner tube 1. This allows for direct fastening to the interface edge, achieving a locking effect and preventing detachment. Using the clips 9 connection method, even slight differences between the inner tube 1 and the connector can be addressed. Moreover, to provide appropriate isolation and coverage at the lower end, the covering component 5 is a waterproof sleeve that wraps around the outer side of the lower end of the extended outer tube 2. The waterproof sleeve can be made of PC soft material and can be easily cut to fit the tolerance of the joint gap.

[0039] In practical application, for monocrystalline silicon pressure sensors with external threaded connectors, the inner wall of the inner tube 1 has internal threads, enabling convenient threaded connection. Furthermore, to allow users to quickly identify the corresponding monocrystalline silicon pressure sensor model, a label can be distributed on the outer wall of the extended outer tube 2. Additionally, to prevent water vapor intrusion at the joint interface, a sealing ring is distributed on the upper end of the inner wall of the inner tube 1.

[0040] Furthermore, the inner wall of the inner tube 1 is coated with an anti-static coating 11, which can prevent electrostatic interference and improve data transmission accuracy. Alternatively, an anti-static sticker can be attached to the inner wall of the inner tube 1, achieving the same anti-static effect as the outer part of the interface.

[0041] The working principle of this utility model is as follows:

[0042] Connect the upper end of the inner tube 1 to the connector of the monocrystalline silicon pressure sensor. Then, extend the outer tube 2 along the length of the terminals on the monocrystalline silicon pressure sensor connector, so that the inner tube 1 and the outer tube 2 cover the connector and terminals.

[0043] Next, the covering component completely blocks the connection gap between the wiring terminal and the data transmission device.

[0044] For ease of implementation, this invention can be integrated during the manufacturing process of the single-crystal silicon pressure sensor. This ensures that its connectors and terminals are waterproof, anti-static, and resistant to cuts and scratches.

[0045] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0046] 1. By connecting the inner tube and extending the outer tube, effective adjustment of the covering length can be provided, and appropriate isolation and protection can be provided for the joints and terminals.

[0047] 2. Through the cooperation of the guide groove and guide block, the relative length of the inner tube and the extended outer tube can be accurately positioned, avoiding improper retraction.

[0048] 3. It has an independent positioning component that can be effectively combined with the connector side of the monocrystalline silicon pressure sensor.

[0049] 4. A cover component is added to prevent water splashing from affecting the location of the connection terminal due to gaps caused by joint tolerances.

[0050] 5. The overall structure is simple and can be directly installed on existing monocrystalline silicon pressure sensors, making it easy to use.

[0051] Furthermore, the directions or positional relationships described in this utility model are based on the directions or positional relationships shown in the accompanying drawings. They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
