Description

Connector

Affiliated technical field

The utility model belongs to the line connector group in International Patent Classification (IPC), i.e. H01R, the particularly waterproof of Holiday lamp connection usefulness, the slotting connector of counnter attack.

Background technology

At present, decorative lamp or Holiday lamp connect the connector of usefulness, by plug body and socket and separately plug, jack forms, need only during use plug inserted jack.When running into the pouring of it rains or water, rainwater is easy to infiltrate from the faying face between plug body and the socket, causes electric short circuit.Simultaneously require plug that the branch of positive and negative electrode is arranged sometimes, prior art then can't satisfy.Through Chinese patent information network retrieval, with H01R classification number or when being keyword retrieval with " plug ", can detect more than 15000 patent.But when being keyword, only detect the 96216285.X patent, be that mainly the plastomer periphery establishes O shape groove, joins O shape circle with " antiseep "; When being keyword, only detect patent with " counnter attack is inserted " No. 02271847.8, mainly adopt three asymmetric plug, jacks that vary in size.Satisfying the connector that antiseep, counnter attack insert simultaneously fails to detect.

The utility model content

The purpose of this utility model is to solve water-impervious, the counnter attack of the line connector of light fixtures such as decorative lamp, Holiday lamp and inserts a difficult problem.

It is as follows to disclose new technical scheme:

A kind of Holiday lamp connects the connector of usefulness, comprises polymer plug body, socket at least and is injection-moulded in together electric wire, is fixed with two or three plugs on the plug body, and corresponding jack is arranged on the socket.The plug body periphery is shaped on a circle convex shoulder, is inserted in the fastening cap of plug body, and end and convex shoulder are tight against in it, and the pin thread of the negative thread on interior week and socket periphery close-fitting mutually; Socket has a location breach, has the plush copper that breach therewith matches on the plug body.

According to such scheme, because the effect of convex shoulder and fastening cap, rainwater can not infiltrate the faying face of plug body and socket.The cooperation of locating notch and plush copper is arranged simultaneously, prevented anti-inserting.

Wherein: 1, electric wire 2, plug body 3, convex shoulder 4, negative thread 5, plush copper 6, breach 7, plug 8, jack 9, socket 10, anti-skidding line 11, fastening cap

Embodiment

A kind of Holiday lamp connects the connector of usefulness, comprises polymer plug body 2, socket 9 at least and is injection-moulded in together electric wire 1, is fixed with two or three plugs 7 on the plug body 2, and corresponding jack 8 is arranged on the socket 9.Plug body 2 peripheries are shaped on a circle convex shoulder 3, are inserted in the fastening cap 11 of plug body, and end and convex shoulder 3 are tight against in it, and the pin thread of the negative thread 4 on interior week and socket 2 peripheries close-fitting mutually; Socket 9 has a location breach 6, has the plush copper 5 that breach 6 therewith matches on the plug body 2.The outer surface of plug body 2 and socket 9 is shaped on anti-skidding line 10.

Because when fastening, plug body 2 and socket 9 trackslip easily, therefore be shaped on anti-skidding line 10 on its outer surface.

Claims (2)

1, a kind of Holiday lamp connects the connector of usefulness, at least comprise that polymer plug body (2), socket (9) are injection-moulded in electric wire (1) together, be fixed with two or three plugs (7) on the plug body (2), corresponding jack (8) arranged on the socket (9), it is characterized in that:

A, plug body (2) periphery are shaped on a circle convex shoulder (3), are inserted in the fastening cap (11) of plug body (2), and end and convex shoulder (3) are tight against in it, and the pin thread of the negative thread on interior week (4) and socket (9) periphery close-fitting mutually;

B, socket (9) have a location breach (6), have the plush copper (5) that breach (6) therewith matches on the plug body (2).

2, connector as claimed in claim 1 is characterized in that the outer surface of plug body (2) and socket (9) is shaped on anti-skidding line (10).
