Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically relating to a protective cap for the electrical connector of a sensor. Background Technology

[0002] In modern industrial automation, the Internet of Things, and smart devices, sensors are increasingly widely used. Electrical connectors, as key components connecting sensors to external devices, directly impact the normal operation of the entire system. To prevent interference and damage from external factors such as dust, moisture, and mechanical impacts, electrical connectors are typically equipped with protective caps.

[0003] Existing protective caps for sensor electrical connectors present numerous problems in practical use. Firstly, the connection between the cap and the connector is not robust enough, easily loosening or even detaching under vibration or tensile forces, leading to protective failure. Secondly, the caps themselves lack structural strength, making it difficult to maintain good protective performance over extended periods in complex environments. For example, the lack of reinforcing structures can cause deformation under pressure, affecting the protection of the connector. Furthermore, some caps are inconvenient to install, lacking effective guiding structures, resulting in low installation efficiency and the potential for damage to the connector due to improper handling. Therefore, there is an urgent need to design a sensor electrical connector protective cap with a more rational structure, stable installation, and excellent protective performance. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a protective cap for the electrical connector of the sensor, the protective cap including a tube body, a top cover at the upper end of the tube body, a buckle on one side of the electrical connector, a vertical sliding groove for the buckle to move on one side inside the tube body, and a protrusion for the buckle to hook in the vertical sliding groove.

[0005] As a preferred embodiment of the above technical solution, the top cover extends outwards from all four sides to form a cover edge.

[0006] As a preferred embodiment of the above technical solution, the inner wall of the tube is provided with several vertically arranged reinforcing ribs.

[0007] As a preferred embodiment of the above technical solution, the lower end of the tube is provided with a guide chamfer.

[0008] As a preferred embodiment of the above technical solution, the upper surface of the buckle has an inclined guide surface.

[0009] As a preferred embodiment of the above technical solution, the upper and lower ends of the protrusion smoothly transition with the bottom of the vertical groove.

[0010] As a preferred embodiment of the above technical solution, the protective cap is integrally molded from plastic.

[0011] The beneficial effects of this utility model are as follows: The protective cap for the sensor electrical connector of this utility model, with its vertical sliding groove, protrusion, and snap-fit ​​mechanism inside the tube, securely engages the protective cap with the electrical connector, resisting vibration and external pulling forces, preventing the protective cap from falling off, and ensuring continuous safety protection for the electrical connector. The extended rim of the top cover prevents dust and rainwater from entering, and combined with the reinforcing ribs on the inner wall of the tube, it not only enhances the protective cap's resistance to compression and prevents deformation, but also effectively extends the service life of the electrical connector and improves the ease of operation when removing the protective cap. The chamfered guide at the lower end of the tube and the inclined guide surface of the snap-fit ​​provide clear guidance for installation, reducing installation difficulty, improving installation efficiency, and preventing damage to the electrical connector. The smooth transition between the protrusion and the bottom of the sliding groove makes the snap-fit ​​operation smoother. The one-piece plastic molding process simplifies the production process, reduces costs, and ensures the structural integrity and sealing performance of the protective cap.

[0014] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1-2 As shown, the sensor's electrical connector protective cap includes a tube body 1 with a top cover 2 at its upper end. A latch 4 is located on one side of the electrical connector 3. A vertical groove 5, allowing the latch 4 to move, is located on one side inside the tube body 1. A protrusion 6, within the vertical groove 5, is provided for the latch 4 to hook onto. After the sensor is manufactured, the electrical connector is inserted into the protective cap, and the latch 4 and protrusion 6 engage to secure the connector. The engagement of the vertical groove 5 and the latch 4 provides a fault-prevention function. The protective cap protects the electrical connector during storage and transfer. When the sensor needs to be connected to power via the electrical connector 3 after installation, the protective cap is removed.

[0018] Furthermore, the top cover 2 extends outwards around its perimeter to form cover edges 7. Cover edges 7 facilitate the removal of the protective cap from the electrical connector after the protective cap is gripped.

[0019] Furthermore, the inner wall of the tube body 1 is provided with several vertically arranged reinforcing ribs 8. The reinforcing ribs 8 improve the structural strength of the protective cap, enhance the tightness of the connection with the electrical connector, and prevent the protective cap from loosening and falling off.

[0020] Furthermore, the lower end of the tube body 1 is provided with a guide chamfer 9. The guide chamfer 9 facilitates the insertion of the electrical connector 3 into the protective cap.

[0021] Furthermore, the upper surface of the buckle 4 has an inclined guide surface 10. The inclined guide surface 10 further facilitates the insertion of the electrical connector 3 into the protective cap.

[0022] Furthermore, the upper and lower ends of the protrusion 6 smoothly transition into the bottom of the vertical groove 5. This allows for smooth installation and removal of the protective cap.

[0023] Furthermore, the protective cap is molded from a single piece of plastic. Plastic protective caps are low-cost, provide a good seal, and offer long-term protection for the sensor's electrical connectors.

[0024] It is worth mentioning that the sensor and other technical features involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent.
