Description

Technical Field

[0001] This utility model belongs to the field of communication connectors, and in particular relates to a grounding device for integrated terminals. Background Technology

[0002] Existing electrical connectors typically include a signal terminal housing and a ground terminal housing. The signal terminal housing is used to connect to the signal terminal housing, and the ground terminal housing is used to connect to the ground terminal housing. For ease of installation, electrical connectors usually include an insulating body with a housing groove and conductive terminals assembled in the housing groove. A shielding layer is formed on the inner surface of the housing groove, and an insulating layer is formed on the shielding layer by physical plating. The shielding layer provides electromagnetic shielding for the conductive terminals, and the insulating layer isolates the conductive terminals from the shielding layer, preventing short circuits. Because the insulating layer is formed on the inner surface of the housing groove by physical plating, its thickness is small, making it easy for the conductive terminals to scratch the insulating layer and short circuit with the shielding layer. If the insulating layer thickness is too large, it will affect the size of the housing groove, making it difficult to assemble the conductive terminals. Furthermore, this type of electrical connector is only suitable for two-way connection applications.

[0003] For marine equipment, it is necessary to simultaneously meet the requirements of using the signal terminal and the grounding terminal separately and connecting them in the same location. Currently, connectors that meet these requirements include a body with an insulating pad, on which are provided posts for accommodating the signal terminal and posts for accommodating the grounding terminal. The two posts are connected by a shorting tab, which is made of conductive material and is detachably connected between the two posts. When the two posts are used separately, the shorting tab is removed. When the two posts need to be used together, the shorting tab is installed to connect the two locations.

[0004] However, for smaller terminal devices, smaller and more sophisticated connectors are required. Existing connectors are difficult to meet the requirements, and their structures are complex and costly. Utility Model Content
