Description

Technical Field

[0001] This application relates to the field of connector technology, specifically waterproof and insulated connectors. Background Technology

[0002] Connectors are components that enable circuit connections and ensure stable transmission of electrical energy and signals. Waterproof and insulated connectors, with their combined waterproof sealing and insulation protection properties, can effectively isolate external moisture, dust, and corrosive media, and prevent faults such as short circuits and leakage. They are crucial for improving the reliability and safety of electrical systems in complex environments and have become an essential component for various outdoor and humid environment equipment.

[0003] Some existing waterproof and insulating connectors achieve their connection and waterproof sealing functions primarily through threaded connecting sleeves. These connectors mainly consist of a male connector, a female connector, an insulating shell, and a threaded connecting sleeve. The connecting sleeve connects to one end of the connector, while the other end is threaded to the corresponding connector. During installation, the operator aligns the male and female connectors and then rotates the connecting sleeve to ensure the threads are tightly engaged. The locking force of the threaded engagement is used to fix the connector position, while the insulating shell provides electrical isolation, ensuring safe use.

[0004] However, since the stability of the connection depends heavily on the tightness of the threads, if the connector sleeve is not fully tightened or the thread engagement depth is insufficient during installation, the connector sleeve is prone to loosening under conditions such as vibrations generated during equipment operation, changes in ambient temperature, or external force. Loose threads can lead to an increase in the joint gap, thereby weakening the waterproof sealing performance and allowing external moisture to easily seep into the connector, causing faults such as short circuits. Therefore, it is necessary to provide waterproof and insulated connectors to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a waterproof and insulating connector, which solves the problem that the connection stability of some existing waterproof and insulating connectors depends on the tightness of the threads. If the connecting sleeve is not fully tightened, it is easy to loosen later under vibration, temperature change or external force, which leads to increased joint gap, weakened waterproof sealing performance, water vapor infiltration and short circuit.

[0007] The technical solution adopted by this application to solve its technical problem is: a waterproof and insulated connector, comprising: Mother head seat; male head seat; A connecting sleeve, which is installed on the female connector and the male connector, is suitable for isolating external moisture; An auxiliary positioning component is mounted on the male connector. The auxiliary positioning component includes a positioning hemisphere for preventing the connector from becoming loose. An adapter sleeve is mounted on the connecting sleeve, and the adapter sleeve has an arc groove that fits the positioning hemisphere.

[0008] Furthermore, the female head seat is provided with a first external thread, the male head seat is provided with a second external thread, and the connecting sleeve is provided with an internal thread that is compatible with the first external thread and the second external thread.

[0009] Furthermore, a limiting groove is provided on the female connector, and a limiting strip adapted to the limiting groove is installed on the male connector.

[0010] Furthermore, the connecting sleeve is equipped with anti-slip particles, which are suitable for increasing the friction force when the connecting sleeve rotates.

[0011] Furthermore, the auxiliary positioning component also includes a positioning cover installed on the male head seat, a positioning sleeve installed on the positioning cover, a positioning ring installed on the positioning sleeve, a spring installed on the positioning ring, an intermediate plate installed at one end of the spring, and a positioning hemisphere installed on the intermediate plate.

[0012] Furthermore, an intermediate post that can slide along the axial direction of the positioning ring is installed on the intermediate plate, and a warning ring is provided on the intermediate post.

[0013] Furthermore, the spring causes the positioning hemisphere to maintain a downward motion tendency.

[0014] The beneficial effects of this application are: the waterproof and insulating connector provided by this application can effectively prevent the connecting sleeve from loosening by matching the positioning hemisphere of the auxiliary positioning component with the arc groove on the connecting sleeve adapter sleeve. At the same time, the connecting sleeve can isolate external moisture, thereby ensuring the waterproof sealing performance and circuit connection stability of the connector.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figures 1-4 As shown, it includes a female connector 1 and a male connector 2. The female connector 1 is one of the components of the connector that realizes circuit connection and is used to adapt and connect with the corresponding external circuit or equipment. A first external thread 11 is provided on the female connector 1, and a limiting groove 12 is provided at one end of the female connector 1. The limiting groove 12 plays a guiding and initial positioning role during the docking process of the female connector 1 and the male connector 2, ensuring that the two can be quickly aligned during connection and preventing misalignment.

[0021] A second external thread 21 is provided on the male connector 2. The second external thread 21 has a similar function to the first external thread 11 and works together with the connection part to achieve a stable connection between the female connector 1 and the male connector 2. A limiting strip 22 adapted to the limiting groove 12 is fixedly installed on the inner wall of one end of the male connector 2. When the female connector 1 and the male connector 2 are connected, the limiting strip 22 is inserted into the limiting groove 12, which not only enhances the accuracy of positioning, but also effectively prevents the female connector 1 and the male connector 2 from rotating relative to each other during the connection process, ensuring the smooth progress of subsequent connection operations.

[0022] like Figures 1-3 As shown, a waterproof component 3 is installed on the female connector 1 and the male connector 2. This waterproof component 3 is a structure that makes the connector waterproof. Its function is to effectively isolate external moisture, dust, corrosive media, etc., and ensure the safe and stable operation of the internal circuit. It includes a connecting sleeve 31 installed on the female connector 1 and the male connector 2. The connecting sleeve 31 has an internal thread 32 that is adapted to the first external thread 11 and the second external thread 21. The connecting sleeve 31 is the component that connects the female connector 1 and the male connector 2. Through the internal thread 32 of the connecting sleeve 31 engaging with the first external thread 11 of the female connector 1 and the second external thread 21 of the male connector 2, the female connector 1 and the male connector 2 are tightly connected into a whole, thereby forming a good sealing structure. Specifically, the adaptation of the internal thread 32 with the external thread ensures that the thread engagement between the connecting sleeve 31 and the female connector 1 and the male connector 2 is tight, improving the stability and sealing of the connection.

[0023] Multiple sets of anti-slip particles 33 are fixedly installed on the connecting sleeve 31. The anti-slip particles 33 increase the friction when the operator rotates the connecting sleeve 31, making it easier and more convenient for the operator to install or remove the connecting sleeve 31. This prevents the installation accuracy or disassembly efficiency of the connecting sleeve 31 from being affected by hand slippage, and improves the overall convenience of operation.

[0024] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an auxiliary positioning component 4 is installed on the male connector 2. This auxiliary positioning component 4 is used to prevent the connecting sleeve 31 from loosening under subsequent working conditions due to incomplete tightening, thereby ensuring the waterproof sealing performance of the connector and the stability of the circuit connection. It includes a positioning cover 41 fixedly installed on the male connector 2. The positioning cover 41 provides an installation carrier and space for other components of the auxiliary positioning component 4, and plays a role in protecting and limiting the internal components. Multiple sets of positioning sleeves 42 are fixedly installed on the positioning cover 41. The positioning sleeves 42 are used to accommodate and install the other components of the auxiliary positioning component 4, ensuring that these components can function stably.

[0025] A positioning ring 421 is fixedly installed at one end of the inner wall of the positioning sleeve 42. The positioning ring 421 serves to limit and support the movement. A spring 43 is fixedly installed on the positioning ring 421. A middle plate 44 is fixedly installed at one end of the spring 43. A positioning hemisphere 45 is fixedly installed on the middle plate 44. An adapter sleeve 46 is fixedly installed at one end of the connecting sleeve 31. One end of the adapter sleeve 46 is inserted into the positioning cover 41. Multiple sets of arc grooves 47 adapted to the positioning hemisphere 45 are formed at one end of the adapter sleeve 46. The spring 43 provides elastic drive. The force-bearing component ensures that the positioning hemisphere 45 always maintains a downward movement trend. At the same time, the positioning hemisphere 45 is a component for positioning and preventing loosening. Its shape is adapted to the arc groove 47 and can be inserted into the arc groove 47 under the action of the spring 43, thereby positioning and limiting the connecting sleeve 31. When the connecting sleeve 31 is rotated to the installation position, the positioning hemisphere 45 will be pushed into the arc groove 47 by the spring 43. At this time, the position of the connecting sleeve 31 is fixed, making it less likely to loosen under operating conditions such as equipment vibration, changes in ambient temperature, or external force contact.

[0026] An intermediate post 48 is fixedly installed on the upper end face of the intermediate plate 44, which can slide along the inner wall of the positioning ring 421. The intermediate post 48 can slide freely within the positioning ring 421, thereby driving the intermediate plate 44 and the positioning hemisphere 45 to move together, realizing the extension and retraction of the positioning hemisphere 45. A warning ring 49 is provided on the intermediate post 48. The warning ring 49 is an indicator component used to indicate to the staff whether the connecting sleeve 31 is installed in place and whether it is loose. When the positioning hemisphere 45 is inserted into the arc groove 47, the warning ring 49 is located inside the positioning sleeve 42 and cannot be seen by the staff. This indicates that the connecting sleeve 31 has been installed in place, the thread engagement depth is sufficient, and the connection is stable and reliable. When the connecting sleeve 31 becomes loose, the positioning hemisphere 45 will disengage from the arc groove 47, and the intermediate post 48 will move upward under the action of the spring 43. The warning ring 49 will then protrude from the positioning sleeve 42. By observing whether the warning ring 49 is protruding, the staff can promptly detect the looseness of the connecting sleeve 31 and carry out timely maintenance to avoid the joint gap from increasing due to loose connection, which would weaken the waterproof sealing performance and allow external moisture to seep into the connector, causing faults such as short circuits.

[0027] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
