Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, and in particular relates to an integrated sealing assembly for electrical connectors. Background Technology

[0002] In the structure of vacuum electrical signal transmission connectors used in semiconductor projects, a glass sintered structure is designed to ensure a gas-tight seal on both sides. The connector is welded using laser sealing technology, which generates enormous thermal stress instantaneously during the process. This thermal stress impacts the sintered glass elements of the connector. Furthermore, multiple electrical connectors need to be integrated and welded within a limited space, ensuring welding quality and preventing interference between connectors during cable insertion and removal. Therefore, a sealing assembly with a structural design that meets the requirements for sealed installation is needed.

[0003] Patent document No. 217239807U discloses a vacuum connector in which the filling part is filled into a sealing groove, which helps to increase the sealing between the adapter flange and the base, thereby preventing the pressure environment inside the sealed container from being damaged. This connector is used for sealed containers for high and low pressure testing, and its application field is different from that of this application. Utility Model Content

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention incorporates a first connecting ring and a second connecting ring for stress relief. The instantaneous thermal stress generated during the welding process between the adapter assembly and the flange is released through these rings, preventing the thermal stress from impacting the glass of the adapter assembly and thus affecting the sealing performance. This invention is a structure for connecting a high-density, low-pressure hybrid feedthrough adapter assembly to a flange, applied in semiconductor projects to achieve a gas seal between the vacuum and atmospheric sides of the equipment. The connector is welded to the flange to enable electrical signal transmission on both sides. Attached Figure Description

Detailed Implementation

[0022] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0023] Example:

[0024] like Figures 1 to 6As shown, an integrated sealing assembly for an electrical connector includes a flange 1 and an adapter assembly. The flange 1 is provided with a first mounting groove 11, a second mounting groove 12 and a handle 6. The first mounting groove 11 is provided with a mounting hole. The adapter assembly is connected to the flange 1 through the mounting hole and passes through the flange 1. A seal 7 is provided in the second mounting groove 12.

[0025] The mounting holes include a first mounting hole 13, a second mounting hole 14, a third mounting hole 15 and a fourth mounting hole 16, and the upper part of each mounting hole is provided with a groove for accommodating the first connecting ring 9 and the second connecting ring 10.

[0026] For the integrated welding of high-density adapter components, it is also necessary to ensure that the cable end connectors do not interfere with each other when they are plugged in or out. Therefore, the position of the mounting holes on flange 1 needs to be designed according to the actual situation so that the spacing between the connectors after welding is optimal.

[0027] The adapter assembly includes a first connector 2, a second connector 3, a third connector 4, and a fourth connector 5. The first connector 2 is connected to the flange 1 through a first mounting hole 13, the second connector 3 is connected to the flange 1 through a second mounting hole 14, the third connector 4 is connected to the flange 1 through a third mounting hole 15, and the fourth connector 5 is connected to the flange 1 through a fourth mounting hole 16.

[0028] The first connector 2, the second connector 3, and the third connector 4 are provided with a first connecting ring 9. The first connecting ring 9 has a groove and is connected to the flange 1. The first connecting ring 9 surrounds the upper edge of the first connector 2, the second connector 3, and the third connector 4. The first connector 2, the second connector 3, and the third connector 4 have the same structure, differing only in size. The first connector 2, the second connector 3, and the third connector 4 may be provided with screw holes for fixing with the connector.

[0029] The first connector 2 is a power connector, with 3 units; the second connector 3 is a 15-pin low-frequency connector, with 17 units; the third connector 4 is a 9-pin low-frequency connector, with 4 units; and the fourth connector 5 is an RF connector, with 9 units. The first connector 2, second connector 3, and third connector 4 are rectangular, while the fourth connector 5 is cylindrical. After press-fitting, the tops of the first connector 2, second connector 3, and third connector 4 are flush with the tops of the corresponding mounting holes.

[0030] The fourth connector 5 is provided with a second connecting ring 10, which has a groove. The second connecting ring 10 is connected to the flange 1 and surrounds the upper edge of the fourth connector 5. The first connecting ring 9 and the second connecting ring 10 are used for stress relief.

[0031] The second mounting groove 12 is dovetail-shaped and is used to provide space for the deformation of the rubber seal 7. To ensure the sealing performance during installation, the roughness of the bottom surface of the dovetail groove shall not exceed Ra0.4.

[0032] The adapter assembly is interference-fitted to the mounting hole, and the adapter assembly is pressed into the mounting hole of the flange using a press-fit tool.

[0033] The flange 1 is provided with a first screw hole 17, which can be used to connect and fix the bolt to the corresponding screw hole of the equipment mounting plate 8 after passing through the first screw hole 17, thereby fixing it to the equipment.

[0034] Figure 4 This refers to the adapter assembly after press-fitting and welding. After welding, the overall sealing performance of the integrated sealing assembly needs to be tested to ensure a vacuum leakage rate ≤1×10⁻⁶. -10 Pa.m 3 / s, to achieve overall airtightness of the integrated sealing assembly.
