CN2555561Y - Dust-proof sleeve of plug - Google Patents

Abstract

A dustproof cover of a plug is a hollow ring body with equal sections, which is made from the macromolecular material. A top opening of the dustproof cover of the plug is corresponding with the size and shape of the bottom edge of a plug body and extends upwards to form a section of joining segment, which is mounted and positioned with the bottom edge of the plug body. The edge of the opening extends downwards and obliquely to form a trumpet-shaped oblique wing, the length of which is shorter than the length of a plug connecting polar. When the plug and a socket are embedded and inserted for linking, the oblique wing is jointed and closely connected with polar holes edges of the socket and forms an obstruct with the outside.

Description

The plug dirt-proof boot

Technical field

The utility model relates to a kind of dirt-proof boot, especially refers to a kind of dirt-proof boot that is applicable to plug.

Background technology

Press plug for people as electricity getting device, existing permanent historical because it has the mobility of intercalation, so all electrical appliances all have the outfit of power taking plug basically.

And the way to take power of plug, be two or three that its insulating body the place ahead is extended connect the utmost point (sheet or shaft-like) be intercalated in socket in the corresponding utmost point hole that is provided with, to form contact and turn-on power.Since plug connect very conducting metal material of the utmost point or utmost point hole interpolation, be infected with uses in or because of extraneous dust, or generation static, consequently influence the power taking quality.For example, the field of employment of electrical appliance is many dust, crinosity wadding or moist place, so that fine dust, batting or moisture are assembled easily and attached work inserting in utmost point hole extremely gone up, if do not cleared up, be easy to generate static, gently then damage electrical appliance, heavy then may cause electric wire to cock off.In addition, when plug is intercalated in socket utmost point hole,, also might leak electricity or the danger of false touch if it connects the utmost point and exposes.

The utility model content

The purpose of this utility model is to provide a kind of plug dirt-proof boot, can effectively intercept dust or batting is gathered in utmost point hole.

For achieving the above object, the plug dirt-proof boot that the utility model provides, it is by the made hollow equal section ring body of height departure material, its open top is corresponding to header body root edge size and appearance, and extend upward one section and be connected section, with socket of header body root edge and location, the then downward oblique extension one trumpet-shaped oblique wing of opening periphery, its length connects the length of the utmost point less than plug; When plug and socket intercalation linked, this oblique wing was promptly fitted on every side with the utmost point hole of socket and is connected airtight, and intercepted with external world's formation.

Wherein macromolecular material is rubber or silica gel.

Wherein be connected a section inwall and be provided with a blocking part, be interlockingly connected with the joint portion of header body root edge.

Wherein blocking part is trip or draw-in groove, and the joint portion is groove or tenon.

Embodiment

As shown in Figure 1 to Figure 3, basically, dirt-proof boot of the present utility model 1 is made by macromolecular material, for example rubber, silica gel etc., and make its elasticity with appropriateness or flexible, in order to combining with plug.This dirt-proof boot 1 is the hollow ring body of an equal section, and its open top 11 is corresponding to the size and the appearance of plug root edge, and opening 11 peripheries extend upward one section and be connected section 12, with the body A socket of plug A, and is fixedly arranged on body A root edge in the mode of tightening.As shown in the figure, opening 11 of the present utility model and to be connected section 12 be rectangle, but not as limit, its enforcement is looked closely various plug appearance and be can be circle, triangle or trapezoidal etc., all belongs to the utility model right request scope.And be to form the dustproof shielding function, these opening 11 bottoms are opened mode (horn-like) one section oblique wing 13 are set beyond periphery, when plug A and socket intercalation, this oblique wing 13 forms applying on every side and coats with the utmost point hole of socket, enter in the utmost point hole of socket loss that may cause or injury to stop with effective obstruct dust, batting or moisture.

Please consult Fig. 3 to Fig. 5 again, this plug A is provided with a groove A3 in its body A1 root edge when dispatching from the factory, and the then prominent relatively trips 121 of establishing one of linking section 12 to embed groove A3, make both combinations more firm and certain.Aforesaid enforcement is also as limit, if the body root edge is a tenon, then and the convergence part thickening, and is provided with a draw-in groove relatively, also can form identical snapping effect.

The assembling of the utility model and plug is very convenient, only the linking section 12 of opening 11 need be socketed on the body A1 of plug A and connect utmost point A2 junction to get final product.The plug and the socket that will have dirt-proof boot 1 are rabbeted when linking, and tiltedly the wing 13 promptly can be fitted with the utmost point hole peripheral of socket, and forms obstruct with the external world, to avoid entering of dust.

Via enforcement of the present utility model, it is incorporated into the body root edge of plug by a dirt-proof boot apace in the socket mode, is the trumpet-shaped oblique wing and socket with it in addition and forms and fit and connect airtight, can effectively stop dust or batting the influence that may cause.

What the utility model disclosed, just preferred embodiment is a kind of, the change of all parts or modification and come from technological thought of the present utility model and be have the knack of this technology the people was easy to know by inference, all do not take off patent right category of the present utility model.

Claims (4)

1, a kind of plug dirt-proof boot, it is by the made hollow equal section ring body of height departure material, its open top is corresponding to header body root edge size and appearance, and extend upward one section and be connected section, with socket of header body root edge and location, the downward oblique extension one trumpet-shaped oblique wing of opening periphery, its length connects the length of the utmost point less than plug; Fitting on every side and connect airtight in the utmost point hole of this oblique wing and socket, forms with the external world to intercept.

2, plug dirt-proof boot as claimed in claim 1 is characterized in that, described macromolecular material is rubber or silica gel.
