[0037] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0038] like Figure 3 , 5 As shown, this utility model provides a combined connector suitable for immersion-type socket boxes, including a combined socket 1, a first connector 2, and a second connector 3. The combined socket 1 includes a socket housing and a male terminal 12. The male terminal 12 is integrally injection molded with the socket housing. The first connector 2 and the second connector 3 are respectively inserted into the two ends of the male terminal 12. The first connector 2 is used to connect to the wiring harness of the battery module 5, and the second connector 3 is used to connect to the wiring harness of the acquisition module 6. A first sealing element 25 is provided on the first connector 2, and the first sealing element 25 abuts against the socket housing, so that the insertion point of the first connector 2 and the male terminal 12 is sealed. Figure 4As shown, a second seal 16 is provided on the socket housing, which is used to seal the socket housing and the battery box 4.

[0039] Understandably, since the acquisition module 6 of the battery module 5 is located outside the battery housing 4, the acquisition line of the battery module 5 needs to be connected to the acquisition module 6 by passing through the side wall of the battery housing 4 using a connector. Therefore, it is necessary to ensure the sealing between the side wall of the battery housing 4 and the connector, as well as the sealing of the connector itself. The male terminal 12 of the combined socket 1 of this utility model is integrally injection molded with the socket housing, ensuring the sealing of the combined socket 1 itself. Furthermore, a second sealing element 16 is provided on the socket housing to ensure the sealing between the combined socket 1 and the battery housing 4. In addition, the first connector 2 is located inside the battery housing 4. By providing a first sealing element 25 on the first connector 2, the connection between the first connector 2 and the combined socket 1 is protected from the influence of immersion liquid.

[0040] In some embodiments, such as Figure 6 As shown, the socket housing includes a base plate 11 and a connector interface 13. The connector interface 13 is arranged on both sides of the base plate 11. The two ends of the male terminal 12 are respectively located in the two connector interfaces 13. The first sealing member 25 is fitted on the first connector 2, so that when the first connector 2 is inserted into the connector interface 13, the first sealing member 25 seals the first connector 2 and the connector interface 13. Figure 6 The diagram illustrates a configuration with four connector interfaces 13, each of which is a cylindrical structure resembling a square, into which the first connector 2 and the second connector 3 can be inserted.

[0041] The first sealing element 25 of this utility model is fitted onto the first connector 2. When the first connector 2 is inserted into the connector interface 13, the first sealing element 25 will tightly adhere to the inner wall of the connector interface 13, thereby sealing the connection between the first connector 2 and the combination socket 1.

[0042] In some embodiments, such as Figure 6 , 10 As shown, the connector interfaces 13 on both sides of the substrate 11 are the first connector 2 interface 13 and the second connector 3 interface 13, respectively. Both the first connector 2 interface 13 and the second connector 3 interface 13 have two symmetrically formed slots 131, as shown... Figure 8 , 9 As shown, the first connector 2 and the second connector 3 are respectively provided with a first buckle 23 and a second buckle 33. The first connector 2 is engaged with the slot 131 of the interface 13 of the first connector 2 through the first buckle 23, and the second connector 3 is engaged with the slot 131 of the interface 13 of the second connector 3 through the second buckle 33.

[0043] In some embodiments, such as Figure 10As shown, a limiting groove 132 is formed on the card slot 131. The limiting groove 132 is elongated, as shown in the figure. Figure 8 As shown, a limiting strip 24 is provided on the first buckle 23, and the limiting strip 24 is arranged in the limiting groove 132. The first buckle 23 elastically abuts against the groove 131. The structure of the second buckle 33 is the same as that of the first buckle 23.

[0044] like Figure 8 As shown, the first latch 23 has a certain elasticity. One end of the first latch 23 is integrated with the first connector 2, and the other end of the first latch 23 is tilted upwards, meaning that the surface of the first latch 23 is not parallel to that of the first connector 2. The first latch 23 can be pressed to fit against the first connector 2. When the external force is released, the first latch 23 automatically returns to its original state. When the first connector 2 is inserted into the interface 13, the two first latches 23 are squeezed by the inner wall of the interface 13, allowing the first connector 2 to be inserted. When the limiting strip 24 is engaged in the limiting groove 132, the first connector 2 is fully inserted.

[0045] In some embodiments, the first seal 25 is fitted onto the end of the first connector 2, such that after the first connector 2 is engaged with the first connector 2 interface 13, the first seal 25 abuts against the bottom of the first connector 2 interface 13.

[0046] Understandably, when the first connector 2 is inserted into the first connector 2, the limiting strip 24 is inserted into the limiting groove 132, so that the first sealing member 25 always abuts against the bottom of the interface 13 of the first connector 2. At this time, the first sealing member 25 is sealed and fitted with the side wall and bottom of the interface 13 of the first connector 2, further ensuring the sealing of the insertion point of the first connector 2.

[0047] In some embodiments, multiple connector interfaces 13 are provided, and male terminals 12 are provided with 64 pins. This can maximize compatibility with the number of voltage and temperature samples of the battery module 5.

[0048] In some embodiments, such as Figure 4 , 6 As shown, a plurality of fixing holes 14 are formed on the substrate 11, and a plurality of riveting posts 15 are provided on the substrate 11. The plurality of fixing holes 14 and the plurality of riveting posts 15 are arranged in a one-to-one correspondence. The riveting posts 15 are used to fix the substrate 11 to the battery housing 4. The riveting posts 15 have blind holes with threads along the axial direction, such as... Figure 4 As shown, after the second sealing member 16 is pressed against the inner wall of the battery box 4, the combination socket 1 is fixed to the battery box 4 by bolts passing through the battery box 4, the second sealing member 16 passing through the fixing hole 14 and the rivet post 15. The rivet post 15 can increase the threaded connection length and ensure the sealing and fixing effect of the combination socket 1.

[0049] In some embodiments, such as Figure 6 As shown, the modular socket 1 includes a mounting bracket 17 for securing the wiring harness of the battery module 5. The mounting bracket 17 is U-shaped and is fixedly connected to the substrate 11.

[0050] like Figure 4 , 5 As shown, a retaining ring 18 is threaded onto the mounting bracket 17. The wiring harness of the battery module 5 is confined to the retaining ring 18, which can prevent the wiring harness from directly contacting the surrounding environmental components and at the same time prevent the first connector 2 from being affected by force, thus ensuring its sealing performance.

[0051] In some embodiments, the first connector 2 is a welded connector, meaning that the wires of the battery module 5 are fixedly connected to the first connector 2 by welding; for example Figure 8 As shown, the first connector 2 includes a first housing 21 and a first female terminal 22, the first female terminal 22 and the first housing 21 being integrally injection molded; as Figure 9 As shown, the second connector 3 is a cold-pressed connector, that is, the second connector 3 and the wire 35 are connected by cold pressing. The wire 35 is provided with a waterproof plug 34. The second connector 3 includes a second housing 31 and a second female terminal 32, which are integrally injection molded with the second housing 31.

[0052] Both the first connector 2 and the second connector 3 are made by integral injection molding of the terminal and the housing, which enhances the sealing performance.

[0053] Secondly, such as Figure 1 , 2 As shown, this utility model provides an immersion-type socket box, including a battery box body 4. A socket mounting hole is opened on the side wall of the battery box body 4. A data acquisition module 6 is fixedly installed on the outer wall of the battery box body 4. A battery module 5 is installed inside the battery box body 4. A combination socket 1 is sealed and installed on the socket mounting hole. A first connector 2 and a base plate 11 are arranged inside the battery box body 4. A second connector 3 is arranged outside the battery box body 4. The wiring harness of the data acquisition module 6 is connected to the second connector 3. The wiring harness of the battery module 5 passes through the fixing ring 18 and is connected to the first connector 2.

[0054] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
