Description

Female head structure of waterproof plug

Technical Field

The utility model relates to the field of waterproof plug structures, in particular to a female head structure of a waterproof plug.

Background

The waterproof plug is a plug with waterproof performance and can provide safe and reliable connection of electricity, signals and the like. The waterproof plug mainly comprises a female connector and a male connector, and when power is connected, the jack of the female connector is in butt joint with a power connection post on the male connector, so that power connection work can be completed. The butt joint leakproofness of waterproof plug has directly influenced the service quality, and simultaneously, the locking performance of taking off of butt joint back electric connection post is also crucial.

When the electric connecting column of the existing waterproof plug is in butt joint, the electric connecting column on the male connector is directly inserted into the jack of the female connector, the electric connecting column is not strong in anti-pulling property, and when external pulling force is applied, the electric connecting column is easily pulled out from the jack, and the anti-loosening performance is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provides a female head structure of a waterproof plug.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

a female head structure of a waterproof plug comprises an insulating shell and an insulating support sleeve arranged on one side of the insulating shell, wherein a jack is arranged in the insulating support sleeve, a power connection terminal assembly is arranged in the jack, and one end of the power connection terminal assembly penetrates through the insulating support sleeve and the insulating shell and extends out;

the port department of jack is equipped with direction clamping unit, and direction clamping unit is including setting up annular installing port on the jack inner wall sets up the direction that presss from both sides tight piece in annular installing port department, sets up the spring at the direction and presss from both sides the tight piece back, the one end of spring with the back fixed connection that the direction pressed from both sides tight piece, the other end with the interior wall connection of annular installing port.

Furthermore, the number of the guide clamping blocks is multiple, and the guide clamping blocks are uniformly distributed in the annular mounting opening in the annular direction.

Furthermore, the electric terminal assembly comprises a female electric pole, an insulating sleeve sleeved on the outer side of the female electric pole and a conducting strip connected to the end part of the female electric pole.

Further, the jacks are consistent with the electric terminal assemblies in number, and the number of the jacks is four.

Further, the insulating housing and the insulating support sleeve are integrally formed.

Furthermore, the end of the guide clamping block is arc-shaped.

The utility model has the beneficial effects that: the port department of the jack of this structure is equipped with direction clamping assembly, direction clamping assembly is including setting up the annular installation mouth on the jack inner wall, the tight piece of direction clamp of setting in annular installation mouth department, the spring of setting at the tight piece back of direction clamp, the one end of spring and the tight piece's of direction clamp back fixed connection, the other end and the interior wall connection of annular installation mouth, when the public joint electric connection post stretches into in the jack and docks with female electric connection post, the tight piece of global extrusion direction clamp of public joint electric connection post, the tight piece of the tight piece radial expansion of a plurality of directions clamp and shrink, when the tight piece shrink of direction clamp, the spring at its back is compressed, under the spring action of spring, the tight piece of direction clamp presss from both sides tight fixed public joint electric connection post, the effect of fixed public joint electric connection post has been played, prevent that the public joint electric connection post after pegging graft pine from taking off.
