Description

Waterproof connector structure for electric vehicle

Technical Field

The utility model belongs to the technical field of waterproof connectors, and particularly relates to a waterproof connector structure for an electric vehicle.

Background

The connector in the electric vehicle mainly plays roles of conducting electricity and transmitting signals, and is not influenced by environmental water vapor in order to ensure the normal operation of the electric vehicle, so that the connector used on the electric vehicle generally has waterproof and moistureproof performances.

The existing waterproof connector for the electric vehicle is generally provided with one or more circles of sealing rings at the joint to block the gap between the connector and the device, so that water vapor is prevented from entering, but the rubber rings are difficult to be completely attached to the gap under the condition that no external force is applied, so that the water vapor still can enter the electric appliance element while the electric appliance element is still wet, and normal operation of the electric appliance is affected.

Disclosure of Invention

The utility model provides a waterproof connector structure for an electric vehicle, which solves the problems in the prior art.

The technical scheme of the utility model is realized as follows:

the waterproof connector structure for the electric vehicle comprises a connector, wherein the connector comprises a connector rear end and an integrally formed connector front end, a wire is further arranged at the end part of the connector rear end, a plug is arranged on the inner side of the connector front end, and a waterproof component is further arranged on the outer side of the connector front end;

the waterproof assembly comprises a first waterproof ring and a second waterproof ring.

Wherein, the waterproof assembly still includes the stop piece that sets up in the waterproof circle rear side of second.

Wherein, the stop piece is made of metal.

The inner side of the front end of the connector is provided with a groove corresponding to the second waterproof ring and the stop piece.

The part of the groove corresponding to the second waterproof ring is a sliding groove, and the part of the groove corresponding to the stop piece is a thread groove.

Wherein the second waterproof ring is a rubber water stop.

After the technical scheme is adopted, the utility model has the beneficial effects that:

according to the waterproof device, the waterproof assembly is arranged, the second waterproof ring arranged in the waterproof assembly is the rubber water stop, the first waterproof ring is extruded forwards when the rubber water stop expands after absorbing water vapor, so that the first waterproof ring is tightly attached between the connector and the device, and the second waterproof ring can be pushed forwards through the stop piece at the rear side during installation, so that the second waterproof ring presses the first waterproof ring, and the first waterproof ring is attached to the gap.

Drawings

In order to more clearly illustrate the embodiments of the utility model or the technical solutions of the prior art, the drawings which are used in the description of the embodiments or the prior art will be briefly described, it being obvious that the drawings in the description below are only some embodiments of the utility model, and that other drawings can be obtained according to these drawings without inventive faculty for a person skilled in the art.

Fig. 1 is a schematic view showing the overall structure of a waterproof connector for an electric vehicle according to the present utility model;

fig. 2 is an exploded view of a waterproof connector for an electric vehicle according to the present utility model.

In the figure, 10, the rear end of the connector; 20. a wire; 30. a plug; 40. a waterproof assembly; 401. a first waterproof ring; 402. a second waterproof ring; 403. a stop plate; 50. a front end of the connector; 60. a groove.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples:

as shown in fig. 1-2, a waterproof connector structure for an electric vehicle comprises a connector, wherein the connector comprises a connector rear end 10 and an integrally formed connector front end 50, the end part of the connector rear end 10 is further provided with a wire 20, the inner side of the connector front end 50 is provided with a plug 30, and the outer side of the connector front end 50 is further provided with a waterproof component 40; the waterproof assembly 40 includes a first waterproof ring 401 and a second waterproof ring 402; the second waterproof ring 402 is a rubber water stop; a groove 60 is formed at the inner side of the front end 50 of the connector and at a position corresponding to the second waterproof ring 402 and the stop piece 403; the waterproof assembly 40 further includes a stopper 403 disposed at the rear side of the second waterproof ring 402;

the part corresponding to the stop piece 403 is a thread groove; the stop piece 403 is convenient to adjust on the front end 50 of the connector along the thread groove, and the stop piece 403 is made of rigid metal; the part of the groove 60 corresponding to the second waterproof ring 402 is a sliding groove; the second waterproof ring 402 can slide on the sliding groove conveniently;

when the connector is used in an electric vehicle, when the second waterproof ring 402 encounters water vapor, the water can be absorbed and expanded, the first waterproof ring 401 with the end part in contact is forced to be pressed towards the gap between the connector and equipment, the gap is blocked, the water prevention is facilitated in a wet environment, the water vapor cannot enter an electric element to cause damage, when the connector is installed, the second waterproof ring 402 can be pressed forwards through the rotating stop piece 403, the second waterproof ring 402 presses the first waterproof ring 401 forwards, the pressure between the first waterproof ring 401 and the equipment is increased, the first waterproof ring 401 is tightly attached to the equipment, no gap is reserved, and the waterproof effect is improved.

Working principle: the waterproof principle of this connector mainly lies in on the waterproof assembly 40, through the waterproof circle 401 of the waterproof circle of first on the waterproof assembly 40 and the waterproof circle 402 of second, the waterproof circle 402 of second is the rubber waterstop, can absorb steam, and the waterproof circle 401 of the waterproof circle of second after the absorption takes place the inflation oppression first waterproof circle 401 to paste tightly on the equipment to the shutoff clearance prevents that steam from getting into, and the while is stopped the spacer 403 and can also be used for adjusting the pressure between waterproof circle 401 and the equipment, does not keep the clearance, has improved the water-proof effects of junction greatly.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
