Abstract

The utility model relates to the technical field of a plug structure. The technical problem to be solved is to provide a plug with safety and easy pulling, convenient use and waterproof performance. The plug comprises an inner core with a contact, a waterproof sleeve, buttons and a shell. The waterproof sleeve is sleeved on the inner core. The buttons are arranged on the waterproof sleeve and move with the waterproof sleeve. The shell is sleeved outside the inner core and the waterproof sleeve. The buttons extend from two sides of the shell. According to the plug, when the plug is needed to be pulled out, only pressing the buttons at two sides of the shell is needed, the waterproof sleeve is pushed out downwards by using the lever principle, the bottom of the waterproof sleeve presses against a patch board, thus a counterforce is formed to pull the plug out, the used force is small, a user can complete the operation with a single hand, the operation is simple, and the plug is convenient to use. At the same time, the electric shock of the fingers can be prevented by the waterproof sleeve, instant power cut can be achieved, the damage of electric appliance is reduced, and the occurrence of safety accidents is prevented.

Description

A kind of plug

Technical field

The utility model relates to the plug construction technical field, more specifically, relates to a kind of plug of safety easy-pulling.

Background technology

In actual life, because plug is comparatively compact with being connected of wiring board, more difficult extracting needs both hands to be operated when unplugg, uses inconvenience.Simultaneously the user is careless or easily get an electric shock when wiring board leak electricity, the initiation security incident.In addition, when plug is applied to the electrical equipment of (such as kitchen or toilet) use under some wet environments, owing to easily contacting with water, easily watered and wetting, have larger application risk while using for a long time.

The utility model content

The utility model is intended to solve the problems of the technologies described above at least to a certain extent.

The purpose of this utility model is to provide a kind of safety easy-pulling, the plug of easy to use and waterproof.

The utility model solves the technical scheme that its technical problem adopts: a kind of plug, comprise inner core, waterproof jacket, button and shell with contact, described waterproof jacket is placed on inner core, described button be located on waterproof jacket and with the waterproof jacket interlock, described shell is placed in the outside of inner core and waterproof jacket, and described button stretches out from the both sides of shell.

Plug of the present utility model, when needs are extracted, only need be pressed the button of shell both sides, and button utilizes lever principle to release waterproof jacket downwards, the bottom of waterproof jacket props up wiring board, thereby form reaction force, plug is extracted, firmly little, the user is singlehanded just can complete, simple to operate, easy to use.Waterproof jacket can prevent that finger from getting an electric shock simultaneously, and the energy instant cut-off, reduces the infringement to electrical equipment, prevents security incident.

In one embodiment, be provided with elastomer between described button.Plug unclamps button after extracting, and button automatically resets by elastomeric elasticity, and waterproof jacket is also retracted original position by button simultaneously, without any operation.Wherein the preferred spring of elastomer, also can select other to have flexible material certainly.In other embodiments, waterproof jacket and inner core entity part also can arrange elastomer.

In one embodiment, the bottom of described waterproof jacket adopts the waterproof material of silica type to make, and can form good sealing state with wiring board, prevent from that a small amount of water from splashing on wiring board to cause short circuit, thus waterproof and dampproof, reduce application risk.Can also prevent that flue dust from entering, avoid occurring loose contact simultaneously.

In one embodiment, described button and shell adopt nonconducting engineering plastics to make, in the situation that comply with the national standard requirements, realize having wide range of applications mass production, are easy to be applied on common household electrical appliance.

In a preferred implementation, the utility model also comprises the protection piece of being located on inner core, and described protection piece is made by anti-burning elastomeric material, can play the effect of protection electric wire.

In one embodiment, described button is provided with antiskid groove, hold comfortable, convenient operation.

In one embodiment, described contact is two pin contacts or three pin contacts, can be applicable to different electrical equipment and wiring board, easily universal, has wider applicability.

The beneficial effects of the utility model are: 1, easily pull out, the user is singlehanded just can complete, simple to operate, easy to use; 2, can prevent that finger from getting an electric shock, and uses safety; 3, good airproof performance, waterproof and dampproof; 4, simple and reasonable, easily mass production; 5, be applicable to different electrical equipment and wiring board, easily universal, there is wider applicability.

Accompanying drawing, only for exemplary illustration, can not be interpreted as restriction of the present utility model; For better explanation embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known configurations and explanation thereof may to omit be understandable.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.

Embodiment 1

As shown in Figure 1 and Figure 2, a kind of plug 100 of the present utility model, comprise inner core 102, waterproof jacket 103, button 104 and shell 105 with contact 101, described waterproof jacket 103 is placed on inner core 102, described button 104 be located on waterproof jacket 103 and with waterproof jacket 103 interlocks, described shell 105 is placed in the outside of inner core 102 and waterproof jacket 103, and described button 104 stretches out from the both sides of shell 105.

Generally, the power that plug is extracted approximates 4.5N, and more difficult extracting needs both hands to be operated when unplugg, uses inconvenience.Plug of the present utility model, when needs are extracted, only need be pressed the button 104 of shell 105 both sides, and button 104 utilizes lever principle to release waterproof jacket 103 downwards, and the bottom of waterproof jacket 103 props up wiring board, thereby form reaction force, plug is extracted.The power of pressing keys 104 is approximately 1.5N, firmly little, and the user is singlehanded just can complete, simple to operate, easy to use.Waterproof jacket 103 can prevent that finger from getting an electric shock simultaneously, and the energy instant cut-off, reduces the infringement to electrical equipment, prevents security incident.
