Description

Power plug with abdication structure

Technical Field

The utility model relates to the technical field of power plugs, in particular to a power plug with a abdication structure.

Background

The power plug is used for being inserted into a corresponding socket (such as a wall socket, a line socket and the like) and supplying power to a rear-end power utilization component or a socket through a matched power line.

The Chinese utility model 'home controller' with the patent number ZL201720444812.4 shows a special shell, and a power supply interface for externally connecting a power supply is arranged on the shell so as to supply power to a circuit board and the like in the home controller. The power interface may be a pin (e.g., three-phase plug, two-phase plug, etc.) or a USB type interface. The housing includes an upper housing and a lower housing and shows that a portion of the lower housing adjacent the power interface forms a reduced step for allowing the safety switch of the jack to be unseated when plugged into an external socket.

The step-shaped arrangement adopted in the above patent is equivalent to dividing the lower housing into an upper portion and a lower portion, and the lower portion is smaller overall, so that a step is formed between the upper portion and the lower portion, and a circle of grooves positioned at the lower portion of the lower housing is formed when the plug is inserted into the external socket. When the user pulls out the plug (the household controller), the user can clamp the fingers into the formed grooves to fasten, so that the plug can be pulled out more easily.

However, due to the difference of the hand sizes of users, users with large hands may not be convenient to insert fingers, sometimes only the two sides of the upper part of the lower shell and the two sides of the upper shell can be selected to be pulled out, and at this time, the effect of clamping and convenient pulling out provided by the step cannot be displayed.

The side surfaces of the existing plug are perpendicular to the upper end surface and the lower end surface, and when the plug is pinched and pulled out, the plug is difficult to pinch the two sides of the shell to pull out from the socket due to sweat or small hand strength on the hand of a user. As a plug to be plugged, it is also important how to enable a user to easily plug the plug from the socket when the plug has a function of giving way to the safety switch of the socket.

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.

Referring to fig. 1-4, a power plug with a yielding structure includes a plug housing 1 and a power obtaining pin 2 disposed on a front end surface 1a of the plug housing, wherein a rear end surface 1b of the plug housing faces away from a corresponding external socket (not shown) when the power plug is plugged into the external socket through the power obtaining pin 2, and the plug housing 1 further has a functional inclined surface 3 disposed gradually shrinking from the rear end surface 1b of the plug housing toward the front end surface 1a of the plug housing.

The function inclined plane that gradually contracts the setting, on the one hand, through the setting of contracting for the part that is close to the preceding terminal surface 1a of plug casing is whole to be less than the part that is close to the rear end face 1b of plug casing, form the structure that can give way to the safety switch of external socket, on the other hand, function inclined plane 3 is as the atress inclined plane simultaneously, when the user pinches the function inclined plane of both sides and pulls out this power plug from corresponding socket backward, the inclination direction of function inclined plane 3 is used for restricting the user's finger and slides backward on the function inclined plane of both sides, make the user more easily pinch the both sides of plug casing 1, and whole inclination setting, the accurate position requirement of kneading tightly is lower to the user, it is more convenient in use.

Many alternative types of power pins are possible, including two pins, AC three pins, high power four pins, etc., and the type shown in fig. 1 is AC three pins.

The power plug may be a part of the power strip, i.e. it receives power from an external socket via the power pin and outputs the power to a socket. The power plug can also be a part of electric equipment, and is used for supplying power to the electric equipment through plugging.

Preferably, the functional inclined surface 3 is formed with a relief groove 4 near the front end surface 1a of the plug housing; wherein, the inner wall surface of the giving way groove 4 opposite to the notch of the giving way groove 4 is continuous adjacent surface with the front end surface 1a of the plug housing. The relief groove 4 is used for enlarging the relief space to adapt to the safety switch of a socket with a larger size. More preferably, the inner side wall surface adjacent to the functional inclined surface 3 on the relief groove 4 is an inward concave arc surface 5. The combination of the abdication groove 4 and the functional inclined plane 3 can form two simultaneous anti-slip modes, the anti-slip effect provided by the abdication groove is better, and the functional inclined plane enables the anti-slip range to be wider.

Further, the inner wall surface of the relief groove 4 opposite to the notch of the relief groove 4 is perpendicular to the front end surface 1a of the plug housing, and more space is provided for the safety switch of the external socket to relief. Referring to fig. 4, further, the front-rear length L1 of the relief groove 4 is not less than 2/3 of the front-rear distance L2 between the front end face 1a of the plug housing and the rear end face 1b of the plug housing.

The wire body outlet 6 of the plug housing 1 is arranged at the bottom of the plug housing 1; the number of the yielding grooves 4 is 2, the 2 yielding grooves are respectively arranged on the functional inclined planes on the left side and the right side of the plug housing 1, so that the plug is more suitable for the pinching habit of a human body, and when the pinching of the plug housing is carried out, a user can pinch the functional inclined planes on the left side and the right side or clamp the functional inclined planes on the left side and the right side with the thumb and the middle finger, and the index finger is made to be put on the functional inclined planes on duty, so that the whole stress is better, and the plug is more stable and anti-slip when the power plug is pulled down.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
