Figure 2 A schematic diagram of the exploded structure of an interconnect connector provided in one embodiment of the present disclosure. Figure 3 for Figure 2 Schematic diagram of the structure enlarged at point A in the middle.

[0034] Combined with reference Figure 1 , Figure 2 and Figure 3 In some embodiments, an embodiment of the present disclosure provides an interconnection connector, including: a shell 10, the shell 10 encloses a housing cavity, the shell 10 has at least one through hole, and the through hole is connected to the housing cavity; an interconnection row 20, the interconnection row 20 extends from a through hole into the housing cavity; the interconnection row 20 includes a terminal 21 extending from the through hole to the outside of the shell 10; a first sealing member 30, the first sealing member 30 abuts against the inner wall of the through hole, and is sleeved on the outer circumferential surface of the interconnection row 20 located in the through hole.

[0035] In some embodiments, the first seal 30 is sleeved on the outer peripheral surface of the interconnection row 20 located in the through hole, thereby the first seal 30 and the interconnection row 20 can be sealed together, and the first seal 30 abuts against the inner wall of the through hole, thereby the first seal 30 can fill the gap between the shell 10 and the interconnection row 20. Therefore, the first seal 30 can ensure the airtightness of the accommodating cavity, and ensure the sealing between the shell 10 and the interconnection row 20, and further improve the protection performance of the shell 10 to the interconnection row 20, thereby improving the service life of the interconnection connector.

[0036] The interconnection bar 20 is provided with at least two wiring terminals 21 extending from the through hole to the outside of the housing 10, and the two wiring terminals 21 are used to be electrically connected to at least two external wiring harnesses respectively. The wiring terminals 21 can be set as threaded wiring holes, and the external wiring harness can be fixedly connected to the copper bar through the threaded wiring holes and bolts, so as to realize the transmission of current. In some other embodiments of the present disclosure, the number of wiring terminals 21 can be set according to actual needs, as long as the transmission power of the interconnection bar 20 is met, and it is not limited here.

[0037] The first sealing member 30 is in contact with the inner wall of the through hole and is sleeved on the outer peripheral surface of the interconnection row 20 in the through hole. The first sealing member 30 is adapted to the cross-sectional shape and cross-sectional area of ​​the through hole and the interconnection row 20 in the thickness direction of the shell 10. As a result, there is no longer a gap at the connection between the interconnection row 20 and the shell 10, and the shell 10 can better protect the interconnection row 20 in the accommodating cavity from dust, water and insulation.

[0038] Specifically, the first sealing member 30 can be a rubber ring. The first sealing member 30 is set as a rubber ring.

[0049] In some embodiments, the third seal 50 also abuts against a portion of the outer circumference of the interconnection row 20 located outside the housing 10 .

[0050] Specifically, the third seal 50 has a certain thickness. The thickness of the third seal 50 can be set to be the same as the thickness of the first seal 30, so that the width of the portion of the third seal 50 that abuts against the outer peripheral surface of the interconnection row 20 located in the accommodating cavity is the same as the thickness of the first seal 30, thereby improving the strength of the third seal 50, thereby further ensuring the sealing between the housing 10 and the interconnection row 20, and improving the connection stability between the housing 10 and the interconnection row 20.

The first seal 30, the second seal 40, and the third seal 50 have an I-shaped cross section in a direction perpendicular to the thickness of the housing 10. Thus, the first seal 30, the second seal 40, and the third seal 50 are ensured to provide sealing between the interconnection row 20 and the housing 10, thereby facilitating the production of the interconnection connector.

[0054] In some embodiments, the first seal 30 , the second seal 40 , and the third seal 50 may be an integrally formed rubber ring, thereby improving the overall structural strength of the first seal 30 , the second seal 40 , and the third seal 50 .
