[0002] A connector is an electrical connection device used to transmit current or signals. Liquid cooling systems, oil pumps, and other liquid-medium devices use liquid as their working medium, and some of their components are immersed in the liquid. Therefore, these devices require connectors to electrically connect components inside the liquid cavity to components outside the liquid cavity. However, existing connectors often have poor sealing between the shell and the terminals, allowing gaps to easily form. This allows liquid to easily seep through the gaps into the connector and overflow into the liquid-medium device, causing leakage. Utility Model Content

[0005] Furthermore, the outer casing has a retaining edge on its peripheral wall.

[0006] Furthermore, it also includes a sealing gasket, wherein the retaining edge is provided with a first groove, and the sealing gasket is disposed in the first groove.

[0046] Example 1

[0047] Please refer to Figures 1 to 4 The first embodiment of this utility model is as follows: an immersion connector includes a housing 1, a terminal 2 and a sealing ring 3. The sealing ring 3 is sleeved on the terminal 2. The housing 1 is provided with a mounting hole 11 and a glue injection groove 12. The terminal 2 passes through the mounting hole 11 and the sealing ring 3 abuts against the inner wall of the mounting hole 11. The glue injection groove 12 is connected to the mounting hole 11 and is used to pour a curing agent so that the curing agent forms a seal 4 between the mounting hole 11 and the terminal 2 after curing.

[0048] This immersion connector can be applied to liquid media devices, which have a cavity for storing a liquid working medium. A portion of the immersion connector is located inside the cavity and immersed in the liquid to connect devices inside the cavity, while a portion of the immersion connector is located outside the cavity to connect devices outside the cavity.

[0049] The immersion connector provided in this embodiment can inject curing agent into the mounting hole 11 through the injection tank 12. The curing agent can be, but is not limited to, epoxy resin. The curing agent can cure between the mounting hole 11 and the terminal 2 to form a dense seal 4. The seal 4 can seal the gap between the housing 1 and the terminal 2. At the same time, the sealing ring 3 can seal the housing 1 and the terminal 2 and prevent the curing agent from overflowing to an unexpected location through the gap between the housing 1 and the terminal 2. The seal 4 of this immersion connector has high reliability and can effectively prevent liquid from the liquid medium device from leaking through the gap between the terminal 2 and the housing 1.

[0050] In some embodiments, the liquid medium device has a mounting hole 11 communicating with the cavity, and an immersion connector passes through the mounting hole 11 so that a portion of its area is immersed in the liquid in the cavity, while a portion of its area is located outside the cavity.

[0051] Preferably, the periphery of the housing 1 is provided with a retaining edge 13, and the retaining edge 13 is provided with a first groove 131. A sealing gasket 5 is provided in the first groove 131. The immersion connector can be tightly fitted with the inner wall of the cavity or the outer wall of the liquid medium device through the retaining edge 13 to ensure the sealing of the cavity and prevent leakage of the liquid working medium of the liquid medium device.

[0052] Please refer to Figure 3 In this embodiment, the outer casing 1 includes a first casing 14 and a second casing 15 connected to each other. The first casing 14 is provided with a first through hole 141, and the second casing 15 is provided with a second through hole 151 communicating with the first through hole 141. The first through hole 141 and the second through hole 151 constitute a mounting hole 11. The split design of the outer casing 1 makes the structure of the first casing 14 and the second casing 15 simple and easy to manufacture, while also facilitating the assembly of the terminal 2 with the outer casing 1. To facilitate the positioning and installation of the first casing 14 and the second casing 15, a positioning groove 142 can be provided on the first casing 14, and a positioning protrusion 152 corresponding to the positioning groove 142 can be provided on the second casing 15.

Specifically, the first connecting portion 21 can be configured as a spring-loaded port connection, and the second connecting portion 23 can be configured as a copper busbar connection.

[0054] Preferably, the sealing part 22 is provided with a fixing protrusion 24 so that the sealing part 22 and the inner wall of the mounting hole 11 are interference-fitted, thereby improving the fixation and sealing between the terminal 2 and the housing 1. The sealing part 22 is provided with a second groove 25, and the sealing ring 3 is disposed in the second groove 25.

[0055] Please refer to Figure 3 , Figure 4 It is easy to see that the immersion connector includes multiple terminals 2, and correspondingly, multiple mounting holes 11 are provided on the external force, each corresponding to one of the multiple terminals 2. In order to improve the insulation performance between two adjacent terminals 2, a spacer 16 can be provided between two adjacent mounting holes 11 to separate the two adjacent terminals 2. The spacer 16 can be, but is not limited to, a spacer baffle or a spacer groove.

[0056] In summary, the immersion connector designed in this invention features a sealing ring 3 fitted onto the terminal 2, and a glue injection groove 12 on the outer shell 1. The sealing ring 3 achieves a sealing effect between the mounting hole 11 and the terminal 2, while the glue injection groove 12 is used to pour curing agent, allowing the curing agent to solidify between the mounting hole 11 and the terminal 2 to form a seal 4. Simultaneously, the sealing ring 3 prevents the curing agent from seeping into unintended areas, thus ensuring the reliability of the seal 4 formed by the curing agent. This immersion connector provided by this invention prevents liquid from penetrating into the interior of the immersion connector through the structure of the sealing ring 3 and the seal 4, ensuring the sealing performance of the immersion connector.
