Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an oblique embedded socket connector. Background Art

[0002] An electrical connector is a device used to connect two active devices, which can transmit current or signals. This type of connector is widely used in military systems such as aviation, aerospace, and national defense. It is also suitable for power and electrical signal connections in many fields such as strategy and tactics, electronic countermeasures, field operations, communication signal connections, aviation, maritime communications and testing, oil and gas field exploration and post and telecommunications, railway command, medical instruments, computer systems, etc. An electrical connector generally includes an insulating body and a plurality of terminals arranged in the insulating body.

[0003] The electrical connectors in the prior art are generally parallel or vertical direct electrical connectors. However, when encountering special limited space, direct electrical connectors cannot meet the requirements of free plugging and unplugging. Therefore, oblique plug-in connectors have emerged, which allow users to insert or unplug the connector in a non-orthogonal direction. This design can provide convenience in space-constrained or special application scenarios.

[0004] However, in order to ensure the reliability and safety of the oblique plug-in electrical connector, the existing oblique plug-in connector is generally equipped with an anti-oblique plug-in mechanism, a floating structure, etc. Although these designs help to improve the accuracy and smoothness of the connection process, these structures not only increase the size of the connector, but also make the structure of the connector more complicated, which does not conform to the lightweight design concept; secondly, the existing oblique plug-in connector generally needs to be connected to the PCB board by bolts; during long-term use, the connector may be detached from the PCB board due to loose bolts, resulting in a shortened service life of the connector.
