[0025] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1, as Figure 1 , Figure 2 and Figure 3As shown, a waterproof rear-mounted dual-control connector socket is provided. A socket sealing gasket 2 is installed on the outside of the rear-mounted socket housing 1. Main power terminal assemblies 3 are installed on both sides of the top of the rear-mounted socket housing 1. Four sets of signal terminal assemblies 4 are installed on one side of the main power terminal assemblies 3. The four sets of signal terminal assemblies 4 are connected to connecting wires 5, which extend to the outside of the rear-mounted socket housing 1.

[0027] In this embodiment, the socket sealing gasket 2 is installed first. The socket sealing gasket 2 is placed on the outer edge of the rear-mounted socket housing 1. During the installation process, it is ensured that the surface of the socket sealing gasket 2 is clean and free of dust, impurities, etc., to ensure its sealing performance. Next, the main power terminal assembly 3 is installed. On both sides of the top of the rear-mounted socket housing 1, special mounting holes and fixing structures are reserved according to the design requirements. The main power terminal assembly 3 is aligned with the mounting holes and fixedly installed to ensure that the main power terminal assembly 3 is installed firmly. Then, four sets of signal terminal assemblies 4 are installed. First, the signal terminal assemblies 4 are connected to the connecting wires 5. Then, on the side of the main power terminal assembly 3 on the rear-mounted socket housing 1, there are also corresponding mounting positions and connection interfaces. The signal terminal assemblies 4 are installed in the corresponding positions in sequence to complete the installation.

[0028] Among them, the rear-mounted socket housing 1 adopts the rear-mounted socket method. When the connector needs to be maintained or replaced, there is no need to disassemble the entire vehicle electrical system on a large scale. It can be operated directly from the outside, which greatly improves the convenience of maintenance, effectively reduces the space occupied by the box, and improves the utilization rate of the vehicle space.

[0029] Among them, the main power terminal assembly 3 uses T2 copper plated with silver material, which can effectively reduce resistance, reduce temperature rise, improve the efficiency and reliability of power transmission, and extend the service life of the connector.

[0030] Among them, by setting two sets of main power terminal components 3, it can achieve two-way signal control and meet the dual control of active and passive.

[0031] Example 2, as Figure 1 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: the top two sides of the rear-mounted socket housing 1 are provided with limiting bosses 101, the top of the main power terminal assembly 3 is mounted on the limiting bosses 101, and several bushings 102 are installed on the outer side of the rear-mounted socket housing 1.

[0032] In this embodiment, during installation, the limiting boss 101 provides a positioning reference for the main power terminal assembly 3. During installation, the installer only needs to align the main power terminal assembly 3 with the limiting boss 101 to quickly complete the initial positioning, which greatly improves the installation efficiency. In addition, several bushings 102 are evenly installed on the outer side of the housing 1. When the housing 1 needs to be installed on the external mounting base, it can be connected to the corresponding mounting holes on the external mounting base through the bushings 102 to achieve a stable installation connection between the housing 1 and the external mounting base.

[0033] The limiting boss 101 and the rear-mounted socket housing 1 are manufactured in one piece, which has good structural strength and stability.

[0035] In this embodiment, during installation, the main power sealing ring 303 is installed into the main power sealing ring mounting groove 302 of the main power terminal 301, and the anti-touch finger cap 306 is installed into the anti-touch finger limiting groove 305 to form the main power terminal assembly 3. Finally, the assembled main power terminal assembly 3 is installed into the rear-mounted socket housing 1 to complete the installation.

[0036] After installation, the main power sealing ring 303 contacts the inner wall of the rear-mounted socket housing 1 to achieve a separate sealing installation, which enhances the overall sealing effect.

[0037] Example 4, as Figure 3 and Figure 6 As shown, this embodiment adds the following structure based on embodiment 1: the signal terminal assembly 4 includes a signal terminal 401, a signal sealing ring mounting groove 402 is provided on the lower side of the signal terminal 401, a signal sealing ring 403 is installed in the signal sealing ring mounting groove 402, a toothed sleeve mounting groove 404 is provided on the lower side of the signal sealing ring mounting groove 402, a toothed sleeve 405 is installed in the toothed sleeve mounting groove 404, a spring tooth 406 is provided around the toothed sleeve 405, and a slot 407 is provided at the corresponding spring tooth 406 of the toothed sleeve 405.

[0038] In this embodiment, during installation, the signal sealing ring mounting groove 402 is installed into the signal sealing ring mounting groove 402 on the signal terminal 401, and then the toothed sleeve 405 is installed into the toothed sleeve mounting groove 404 to form the signal terminal assembly 4. The assembled signal terminal assembly 4 is then installed into the rear-mounted socket housing 1. When the toothed sleeve 405 is installed into the rear-mounted socket housing 1, the spring tooth 406 is in a contracted state under the pressure of the inner wall of the rear-mounted socket housing 1. When the signal terminal assembly 4 is installed in place, the spring tooth 406 pops out from the empty groove 407 and is stuck in the rear-mounted socket housing 1 to achieve a fixed, sealed, and fixed installation.

[0039] Example 5, as Figure 5 and Figure 6 As shown, this embodiment adds the following structure based on embodiment 1: the rear-mounted socket housing 1 is provided with a main power terminal positioning post 103 at the corresponding main power terminal limiting groove 304, and the rear-mounted socket housing 1 is provided with a signal terminal limiting end face 104 at the corresponding spring tooth 406.

[0040] In this embodiment, when the main power terminal assembly 3 is inserted into the rear-mounted socket housing 1 for installation, it is necessary to ensure that the main power terminal positioning post 103 on the rear-mounted socket housing 1 is engaged in the main power terminal limiting groove 304 on the main power terminal 301, so that the main power terminal assembly 3 can achieve a sealed and fixed installation. After the signal terminal assembly 4 is installed in place, the spring tooth 406 pops out from the empty groove 407 and is engaged at the signal terminal limiting end face 104 in the rear-mounted socket housing 1, which also achieves the effect of fixed, sealed and fixed installation.
