Abstract
The utility model discloses an anti-electric-shock plug which comprises a plug housing and metal pins. Each metal pin comprises a fixed connection portion and a plugging connection portion, wherein the fixed connection portion is disposed in the plug housing, and the plugging connection portion extends to the outside of the plug housing. The outside of the plugging connection portion of each metal pin, which is close to one end of the plug housing, is sleeved with an insulating protective layer made from insulating material. One end of the insulating protective layer, which is close to the plug housing, extends into the plug housing or is abutted against the external surface of the plug housing. The plug with the above structure is of a reasonable structure, is safer for use, and allows no power-off situations to occur when the plug slips during use.
Description
Technical field
The utility model belongs to the electric connector structure design field, is specifically related to a kind of electric shock resistant plug.
Background technology
As everyone knows; General household electrical appliance and electric tool all need could be worked through connecting power supply; And the method that connects power supply at present is exactly that the attaching plug that electrical equipment and instrument carry is inserted in the corresponding supply socket, thereby electrical equipment and electric tool energising are used.
The applicant in use finds, the metal pin of plug takes place loosening easily from the jack of socket, and metal pin at this moment near a part of metal plate of plug casing with outside being exposed to; Its end still is arranged in the jack of socket; Also with between the metal contact of socket still form and is electrically connected probably, if the user does not take care, direct or indirect this part plate body that touches; The danger of electric shock just takes place probably, has potential potential safety hazard.
Above deficiency to existing plug existence; Patent documentation CN201927778U discloses a kind of safety plug; Its architectural feature is: the side at plug is provided with elastic corrugated body; Said elastic corrugated body is that cavity is wrapped in the metal insert outside, and an end and plug casing are affixed, and the other end is the openend of retractable.The plug of this kind structure has solved the above-mentioned defective that traditional plug exists really to a certain extent; But also there are some problems simultaneously: when for example plug is in inserting state; The bellows body is extruded; At this moment bellows will inevitably produce a reseting elasticity, and this reseting elasticity can impel plug to come off, and causes outage.Therefore the plug of this kind structure still can not satisfy user's requirement.
Summary of the invention
The purpose of the utility model provides a kind of rational in infrastructure, safe in utilization and can not cause plug in use owing to slippage causes the electric shock resistant plug that cuts off the power supply.
The technical scheme that realizes the utility model purpose is: a kind of electric shock resistant plug comprises plug casing and metal pin; Said metal pin comprises the socket connection portion outer with extending to plug casing of fixed connection portion that is arranged in plug casing;
The socket connection portion of said metal pin is provided with the insulating sheath that adopts insulating material to process near an end outer cover of said plug casing, and said insulating sheath extends to the inside of said plug casing near an end of said plug casing or is connected on the outer surface of said plug casing.
In the technique scheme, the socket connection portion of said plug is provided with groove near an end of said plug casing, and said insulating sheath is arranged in said groove, and the degree of depth of said groove equals the thickness of said insulating sheath correspondence position.
In the technique scheme, said insulating sheath and the said plug casing part that is formed in one.
In the technique scheme, said insulating sheath and the said metallic plug part that is formed in one.
In the technique scheme, said insulating sheath, plug casing and the plug base pin part that is formed in one.
The utlity model has positive effect: the electric shock resistant plug in (1) the utility model is to be provided with the insulating sheath that adopts insulating material to process in the socket connection portion of metal pin near an end outer cover of said plug casing; Owing to this structure is set in use; Then can the direct or indirect plug metal pin that touches of the person of avoiding the use of be exposed to outer metal plate; Then prevent the generation of electric shock accidents; The structure of this kind plug is more reasonable, use safer and can not cause plug in use owing to slippage cause the outage.(2) in the utility model; Through being provided with groove in the socket connection portion of said plug near an end of said plug casing, said insulating sheath is arranged in said groove, and the degree of depth of said groove equals the thickness of said insulating sheath correspondence position; Adopt this structure can insulating protection be set in the groove; Be insulating sheath outer surface and said plug base pin outer surface at grade, structure is more reasonable, and is also more attractive in appearance.
Description of drawings
Fig. 1 is a kind of perspective view of the electric shock resistant plug in the utility model.
Be labeled as shown in the accompanying drawing: plug casing 1, socket connection portion 2, insulating sheath 3.
Embodiment
(embodiment 1)
Fig. 1 is a kind of perspective view of the electric shock resistant plug in the utility model, has shown a kind of embodiment of the utility model.
A kind of electric shock resistant plug, as shown in Figure 1, comprise plug casing 1 and metal pin 2; Said metal pin comprises fixed connection portion that is arranged in plug casing 1 and the socket connection portion 2 that extends to outside the plug casing 1;
The socket connection portion 2 of said metal pin 2 is provided with the insulating sheath 3 that adopts insulating material to process near an end outer cover of said plug casing 1, and said insulating sheath 3 extends to the inside of said plug casing 1 near an end of said plug casing 1 or is connected on the outer surface of said plug casing 1.Owing to this structure is set in use; The plug metal pin that touches that the person of avoiding the use of is direct or indirect is exposed to outer metal plate; Then prevent the generation of electric shock accidents; The structure of this kind plug is more reasonable, use safer and can not cause plug in use owing to slippage cause the outage.
The socket connection portion 2 of said plug is provided with groove near an end of said plug casing 1, and said insulating sheath 3 is arranged in said groove, and the degree of depth of said groove equals the thickness of said insulating sheath 3 correspondence positions.Adopt this structure can insulating sheath 3 be arranged in the groove, promptly the outer surface of the outer surface of insulating sheath 3 and said plug base pin at grade, structure is more reasonable, and is also more attractive in appearance.
Said insulating sheath 3 and said plug casing 1 part that is formed in one; At this moment; Said insulating sheath 3 be directly from the said plug casing 1 extended center be provided with the boss of open-work, the concentric setting of outlet of the placement metal pin of setting on this open-work and the said plug casing 1; In concrete operations, also can said insulating sheath 3 be processed one-body molded with said metallic plug; Said metal pin 2 plastic packagings are in said insulating sheath 3, and the end near plug casing 1 of said insulating sheath 3 is connected on the surface of said plug casing 1; Perhaps with said insulating sheath 3, plug casing 1 and the metal pin part that is formed in one, this moment, said insulating sheath 3, plug casing 1 and plug base pin plastic packaging were integrally formed moulding.
