Description

Technical Field

[0001] This utility model belongs to the field of male connectors, and particularly relates to a male connector. Background Technology

[0002] The controller housing and gearbox housing of a car need to be protected against not only water vapor leakage but also gasoline leakage. Therefore, a male connector is installed between the controller housing and the gearbox housing to achieve electrical connection between the controller housing and the gearbox housing.

[0003] Typically, male connectors work together using a connector body mounted on the cylinder block and a female connector located inside the cylinder block. The female connector primarily mates with the end face of the connector body facing inwards and transmits signals. In existing technologies, the female connector and connector body mostly use a plug-in structure, relying on friction between them to achieve connection. However, the contact surface structure between the female connector and connector body is simple, resulting in low friction. Under high-speed driving conditions, the female connector and connector body are prone to loosening, causing signal transmission distortion. Utility Model Content

[0008] The middle frame is provided with a small terminal support and a large terminal support for fixing the large terminal and the small terminal on the part located inside the second insertion cavity. The second insertion cavity is provided with a ridge for improving the connection strength.

[0009] The female connector has a groove that adapts to the ridge, and the end face of the female connector that contacts the connector body has a small slot and a large slot that adapt to the small terminal support and the large terminal support.

[0010] Preferably, the portion of the middle frame located within the first insertion cavity is provided with a filling layer for sealing the large and small terminals.

[0011] Preferably, a sealing ring is provided on the side of the middle frame near the second insertion cavity, and the sealing ring is positioned close to the middle frame.
