This application claims the benefit of Chinese Patent Application No. CN202222385937.8 filed on Sep. 8, 2022, in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.
The present invention relates to a sealing ring positioning component and a connector comprising the sealing ring positioning component.
In the prior art, a connector typically includes an outer housing, an inner housing, a terminal, and a shielding shell. The inner housing is installed in the outer housing, the terminal is installed in the inner housing, and the shielding shell is sheathed on the outside of the inner housing. The outer housing may be an integral injection molded part, while the shielding shell is usually an integral metal stamped part. The shielding shell may include an end wall and two half shells connected to the end wall. The two half shells are combined to form the outer circumference wall of the shielding shell. In the prior art, in order to facilitate injection molding (e.g., release from a mold), the outer housing needs to have a certain slope. However, as a result, the two half shells of the shielding shell cannot be fully closed, and a certain gap between the splicing edges of the two half shells is created. This gap reduces the electromagnetic shielding effect of the connector.
According to an embodiment of the present disclosure, a sealing ring positioning component adapted to be fitted on an outer housing of a connector to position a sealing ring on the outer housing comprises a peripheral wall and a pushing protrusion formed on an inner peripheral surface of the peripheral wall. The pushing protrusion is adapted to be pushed on the outer sides of two half shells of a shielding shell of the connector such that splicing edges of the two half shells of the shielding shell are in contact with each other.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details.
