Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1, the waterproof single-pairdifferential connector 100 of the present embodiment is a female connector, and is suitable for being used as a vehicle-mounted ethernet connector, and of course, can also be used as a common connector, and is particularly suitable for being used as a connector with high requirements for waterproof and dustproof. The structure of the waterproof single-pairdifferential connector 100 of the present embodiment is described in detail below.
Referring to fig. 1-7, the waterproof single-pairdifferential connector 100 of the present embodiment includes aconnector body 10, aretainer ring 20 and asheath 30, wherein thesheath 30 is a hollow structure with openings at two ends, the hollow structure forms areceiving cavity 31, theconnector body 10 is installed in thereceiving cavity 31 along an axial direction of thereceiving cavity 31, at this time, an end of theconnector body 10 is exposed to an external environment through a front end opening of thereceiving cavity 31 for mating device insertion, and a tail of theconnector body 10 is exposed to the external environment through a rear end opening of thereceiving cavity 31 for electrical connection with acable 40.
Theretainer ring 20 is disposed in thehousing cavity 31 and constantly provides an elastic force for aligning theconnector body 10 to the axial direction of thehousing cavity 31. It can be understood that, since the mating device is inserted into theconnector body 10 with a deviation in the inserting force and/or angle of the mating device, when the mating device is forcibly inserted, theconnector body 10 is easily forced to deviate from the axial position in theaccommodating cavity 31, which causes theconnector body 10 to shift in theaccommodating cavity 31, thereby causing a failed insertion or damaging the terminals of theconnector body 10 due to the forcible insertion.
Thesnap ring 20 is used to correct and adjust theconnector body 10 after being deflected to an axial position by an elastic force, so as to restore to an initial position in thereceiving cavity 31 for normal insertion and removal. The normal plugging can be understood as restoring theconnector body 10 to the axial position for plugging and unplugging the current mating device, and restoring theconnector body 10 to the axial position for plugging and unplugging the subsequent mating device.
Preferably, theconnector body 10 can slightly move along the radial direction of theaccommodating cavity 31, so that theconnector body 10 can be adaptively and finely adjusted along the radial direction in the plugging process to adapt to different plugging angles, thereby avoiding the damage of theconnector body 10 caused by the deviated plugging angle. Theconnector body 10 can be returned to the initial position by thesnap ring 20 even if theconnector body 10 can slightly move in the radial direction of thehousing cavity 31 by thesnap ring 20.
It should be noted that the mating device according to the present embodiment is a device that can be plugged into the waterproof single-pairdifferential connector 100 of the present embodiment, such as a male connector that is adapted to the waterproof single-pairdifferential connector 100.
