Description

Charging connector socket sealing protective cover device

technical field

The utility model relates to a sealing protective cover device for a charging connector socket, which belongs to the technical field of electrical connectors.

Background technique

At present, the high-power DC charging system for electric vehicles is equipped with charging guns for charging stations, and charging connector sockets for electric vehicles. When the car needs to be charged, take out the charging gun on the charging pile and insert it into the charging socket on the car to realize charging. As an important power transmission device in the entire charging system, the charging socket needs to be reliably sealed and protected. Restricted by the installation position on the car, the charging socket needs a sealing protection device that occupies a small space, is easy to operate, and has reliable performance.

Contents of the invention

The purpose of the utility model is to propose a sealing protective cover device for a charging connector socket, aiming at the requirements such as small installation position of the charging socket, simple operation and reliable sealing performance.

The technical solution of the utility model: it is characterized in that it includes a protective cover, a protective cover cavity, a slider, a tension spring, and a fastening screw, wherein the fastening screw connects the protective cover with the protective cover cavity, and the protective cover Two slider chambers are formed with the middle part of the protective cover cavity. The slider is divided into a left slider and a right slider. The slider is placed in the slider chamber of the protective cover cavity. One end of the two tension springs is fixed on the protective cover cavity. The other end of one of the extension springs is fixed on the left slider, and the other end of the other extension spring is fixed on the right slider; the tab on the slider is at a wedge angle of 45°, and the finger operation is concave, and in the transverse direction of the concave surface There are three convex ribs; there are two tongue grooves on the inner wall of the charging socket housing, and there are rubber sealing rings inside the tongue grooves.

The utility model has the advantages of compact structure, comfortable handle, easy operation and reliable sealing protection performance.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model.

Accompanying drawing 2 is a schematic diagram of the position of the tab groove and the rubber sealing ring on the charging socket housing.

In the figure, 1 is the protective cover, 2 is the cavity of the protective cover, 3 is the slider, 4 is the extension spring, 5 is the slider chamber, 6 is the fastening screw, 7 is the tongue groove on the socket housing, 8 It is the rubber sealing ring installed in the socket,

Detailed ways

With reference to accompanying drawings 1 and 2, its structure is to comprise protective cover 1, protective cover cavity 2, slider 3, extension spring 4, fastening screw 6, wherein fastening screw 6 connects protective cover 1 and protective cover cavity 2 connection, so that the middle part forms two slider chambers 5, the slider is divided into a left slider and a right slider, and the left slider and the right slider are placed in the slider chamber 5 of the protective cover cavity 2, and two extension springs One end of 4 is fixed on the protective cover cavity 2, and the other end of one extension spring is fixed on the left slide block, and the other end of another extension spring is fixed on the right slide block. The tab on the slider is at a wedge angle of 45°, and the finger operation part is concave, and there are three convex ribs in the transverse direction of the concave surface. A tongue groove 7 is required on the inner wall of the charging socket, and a rubber sealing ring 8 is also required inside the tongue groove 7 .

When in use, push the protective cover device into the body of the charging socket towards the front of the charging socket. At this time, the tongue on the slider will shrink inward due to the 45° wedge angle and compress the tension spring. When entering the tongue groove 7 on the socket body Finally, the extension spring 4 power is released, and the tabs of the left and right sliders enter the groove simultaneously. At this time, the front face of the protective cover 1 presses the end face of the sealing ring 8 in the socket to realize sealing protection; The tongue of the block shrinks inwardly and disengages from the tongue groove 7 at the same time, and then applies a pulling force according to the B direction of Fig. 2 to pull the protective cover device out of the socket, and the two slide blocks reset simultaneously.

Claims (1)
