[0023] Example
[0024] Reference Figure 1-4 This embodiment of the present invention provides a sealed power SR terminal that is easy to connect, comprising:
[0025] The base 101, the insertion interface 102 formed on the surface of the base 101, the limiting component 103 provided on the side surface of the insertion interface 102, the gasket 104 snapped onto the side surface of the insertion interface 102, the fixing bolt 105 threaded onto the surface of the gasket 104, and the mounting port 106 formed on the side surface of the base 101.
[0026] The limiting component 103 includes a limiting component 103a and an auxiliary component 103b used in conjunction with the limiting component 103a.
[0027] The limiting component 103a includes a sealing strip 103a-1 and a pull rod 103a-2 fixedly connected to the surface of the sealing strip 103a-1. The sealing strip 103a-1 is a rubber strip.
[0028] The limiting component 103a also includes an auxiliary strip 103a-3 fixedly connected to the end of the sealing strip 103a-1, a slider 103a-4 fixedly installed at the end of the auxiliary strip 103a-3, and a groove 103a-5 formed on the inner wall of the base 101.
[0029] Specifically, during use, the power cord is inserted into the socket 102 of the base 101. The pull rod 103a-2 drives the rubber sealing strip 103a-1 to move along the slide groove 103a-5, so that the auxiliary strip 103a-3 and the slider 103a-4 work together to achieve initial positioning. The spring 103b-2 in the auxiliary component 103b pushes the contact plate 103b-4 to fit tightly against the auxiliary strip 103a-3, generating a continuous clamping force to ensure stable connection. The gasket 104 and the fixing bolt 105 cooperate to complete the final fixation. The sealing strip 103a-1 forms an annular sealing barrier in the closed state, effectively isolating external moisture and dust. The entire connection process achieves integrated operation through mechanical linkage, which not only ensures the reliability of electrical connection, but also achieves the dual effects of convenient installation and efficient sealing.
[0030] The auxiliary component 103b includes a partition 103b-1 that contacts the auxiliary strip 103a-3, a spring 103b-2 that is fixedly connected to the surface of the partition 103b-1, and a sliding groove 103b-3 formed on the side surface of the base 101.
[0031] The auxiliary component 103b also includes a contact plate 103b-4 fixedly connected to the end of the spring 103b-2, a sliding block 103b-5 fixedly installed on the side wall of the contact plate 103b-4, and a sliding rod 103b-6 fixedly connected to the surface of the contact plate 103b-4.
[0032] Two sets of auxiliary bars 103a-3 and auxiliary components 103b are provided and are used in conjunction with pull rod 103a-2.
[0033] It should be noted that when the power cord is inserted into the socket 102, the operator pulls the lever 103a-2 to move the two sets of auxiliary bars 103a-3 synchronously. The auxiliary bars 103a-3 are initially positioned by sliding along the slide groove 103a-5 via the slider 103a-4. The spring 103b-2 pushes the contact plate 103b-4 to move the sliding block 103b-5 along the slide groove 103b-3. The slider 103b-6 guides the contact plate 103b-4 to fit tightly with the auxiliary bars 103a-3, generating bidirectional balanced pressure. The partition 103b-1 limits the stroke of the spring 103b-2 to ensure moderate pressure. The two sets of auxiliary components 103b work together to form a symmetrical clamping force. The rubber sealing strip 103a-1 achieves annular sealing during the closing process. Finally, the fixing bolt 105 locks the washer 104 to complete the installation. The entire process realizes a standardized connection procedure, ensuring the mechanical strength and electrical reliability of the power terminal connection.
[0034] In use, the pull rod 103a-2 drives the two sets of auxiliary bars 103a-3 to move synchronously along the slide groove 103a-5 to achieve initial positioning. The spring 103b-2 pushes the contact plate 103b-4 to form a bidirectional balanced pressure with the auxiliary bars 103a-3 through the guiding action of the sliding block 103b-5 and the slide rod 103b-6. The partition plate 103b-1 precisely controls the stroke of the spring 103b-2 to ensure moderate pressure. The rubber sealing strip 103a-1 forms an annular sealing barrier during the closing process. The fixing bolt 105 cooperates with the gasket 104 to complete the final locking. The whole system achieves a four-fold protection mechanism through mechanical linkage, which not only ensures the mechanical strength of the power terminal connection, but also achieves stable and reliable electrical contact, while having excellent moisture-proof and dust-proof performance.
[0035] In summary, the synergistic effect of the two sets of auxiliary strips 103a-3 and auxiliary components 103b forms symmetrical and balanced pressure, ensuring connection stability; the annular closure of the rubber sealing strip 103a-1 achieves complete sealing protection; the cooperation between the spring 103b-2 and the partition 103b-1 provides continuous and moderate clamping force; the guiding structure of the slide groove 103a-5 and the slider 103a-4 makes positioning more accurate; the combination of the fixing bolt 105 and the washer 104 enhances the mechanical fixing strength; the overall structure is compact and reasonable, ensuring both the reliability and safety of the electrical connection, and achieving convenient installation and efficient sealing. At the same time, it has excellent anti-vibration, anti-loosening, moisture-proof and dust-proof performance, significantly extending the service life of the power terminals.
