Abstract

The utility model discloses a series connection structure of an LED lamp string comprising a circuit board, a power cord connected with the circuit board and a plug connected with the LED lamp string in series. A plurality of sockets, which are arranged on the circuit board, and the plug are provided with guiding devices to distinct the polarity respectively. By inserted into the plug, a plurality of LED lamp strings can be used by serially connected in together, which is simple and convenient no matter how many the LED lamp strings are and at the same time because the socket and plug are provided with guiding devices to distinct the polarity, the LED can not be inserted without matching with the plug, the wiring error possibility is eliminated not to burn out the LED lamp or driver, thereby greatly enhancing practicability.

Description

A kind of series connection structure of LED lamp string

Technical field

The utility model relates to the decorative lamp field, particularly a kind of series connection structure of LED lamp string.

Background technology

Energy consumption is low, brightness is high and the characteristics of long service life owing to having for the LED lamp, by the decoration field that is applied to more and more widely, decorate properties was better when a plurality of LED lamps were connected use in DC circuit, the connection of existing LED lamp string, spiral terminal or the binding posts of adopting more, when the quantity of LED lamp is many, be connected in series cumbersomely, efficient is very low; Sometimes also can loose contact and wiring error takes place, burn LED lamp or driver, practicality is not strong.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides the series connection structure of the LED lamp string that a kind of practicality strengthens greatly.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of series connection structure of LED lamp string, comprise circuit board, the power line that is connected with circuit board and the plug that connects with LED lamp polyphone, circuit board is provided with a plurality of sockets, and socket and plug is respectively arranged with the guider of its polarity of difference.

The beneficial effects of the utility model are: circuit board is provided with a plurality of sockets that are used to connect the LED lamp, by being plugged on the socket, the use that just can be serially connected of a plurality of LED lamp strings, the many again serial connections of quantity are also simple and convenient, simultaneously socket and plug is respectively arranged with the guider of its polarity of difference, just can't not insert when LED lamp polarity and socket match, and does not so just have the possibility of wiring error, can not burn LED lamp or driver, practicality strengthens greatly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model;

Fig. 3 is the circuit theory diagrams of the another kind of embodiment of the utility model;

Fig. 4 is the structural representation of the another kind of embodiment of the utility model.

The specific embodiment

Referring to figs. 1 through Fig. 4, a kind of LED series connection joint comprises circuit board 1, the power line 3 that is connected with circuit board 1 and the plug 4 that connects with LED lamp polyphone, and circuit board 1 is provided with a plurality of sockets 2, and socket 2 is respectively arranged with the guider of distinguishing its polarity with plug 4; By being plugged on the socket 2, the use that just can be serially connected of a plurality of LED lamp strings, the many again serial connections of quantity are also simple and convenient, when matching, LED lamp polarity and socket 2 can't not insert, the possibility that does not so just have wiring error can not burnt LED lamp or driver, and practicality strengthens greatly; As a kind of embodiment of the present utility model, described guider comprises the guiding socket 21 that is arranged on the socket 2, and is arranged on the guiding raised line 41 that matches with guiding socket 21 on the plug 4, makes raised line 41 aim at socket 21 insertions during use and gets final product.

As further improvement of the utility model, circuit board 2 is fixed in the connector box, and connector box comprises box body 6 and lid 5, and lid 5 is provided with the opening 7 with socket 2 couplings, and box body 6 and lid 5 are interlocked by the clasp 61 and the button hole 51 of its sidepiece setting; Box body 6 and lid 5 closely surround stringer; can play the effect of protection to circuit board 1 and socket 2; the opening 7 that mates with socket 2 on the lid 5 does not influence use again simultaneously, and it is all quite convenient that the clasp 61 of box body 6 and lid 5 sidepiece settings and button hole 51 open and close terminal box.

As specific embodiment of the utility model, box body 6 and lid 5 can be made split type structure, as shown in Figure 1; Also can make the structure that tangles as shown in Figure 5.

In addition, the quantity of socket 2 can be two, and its electrode is one another in series and gets final product, and also can be increased to a plurality of as required.

Above-mentioned just the utility model preferred embodiment but should not constitute restriction of the present utility model, so long as adopt the technical scheme that is equal to the utility model, and also should be within the protection domain of the invention.
