本发明涉及装饰用串灯。The present invention relates to decorative string lights.
背景技术Background technique
串灯被广泛地用于室内室外装饰，是节日庆祝的必备装饰品。串灯主要是指串联在一个电回路、或者并联在多个电回路、或者先串联后并联在多个电回路中的灯饰。串灯一般具有细长的灯泡、固定灯泡的灯座、及实现灯泡与导线电连接的连接座。多个串灯之间通过两端固定有金属导电端子的导线段相互串联连接起来。专利号为CN201420266522.1、申请日为2014年5月23日的中国发明专利公开的单线串灯中，导线段与灯泡相连的端部固定有导电件，在导线段的靠近导电件的位置固定有固定件，从而在导线段受到相对连接座向外的拉扯力时，不会导致导电件与灯泡脱离，如图1所示。String lights are widely used in indoor and outdoor decoration and are essential decorations for festival celebrations. A string lamp mainly refers to a lamp that is connected in series in one electric circuit, or in parallel in a plurality of electric circuits, or in series and then in parallel in a plurality of electric circuits. String lights generally have an elongated bulb, a lamp holder that holds the bulb, and a connector that electrically connects the bulb to the conductor. The plurality of string lamps are connected to each other in series by wire segments having metal conductive terminals fixed at both ends. In the single-line string lamp disclosed in Chinese Patent Publication No. CN201420266522.1, filed on May 23, 2014, the end portion of the wire segment connected to the bulb is fixed with a conductive member, and is fixed at a position close to the conductive member of the wire segment. There are fixing members, so that when the wire segment is pulled outwardly from the connecting seat, the conductive member is not separated from the bulb, as shown in FIG.
然而，该结构的串灯结构较为复杂，需要设置在串灯设置连接座、在导线段设置导电件以实现导线段与灯光的电连接，并且还需要设置固定件以确保导线段与灯泡的稳定连接。However, the string light structure of the structure is relatively complicated, and it is required to be arranged in the string lamp to set the connection seat, to provide a conductive member in the wire segment to realize the electrical connection between the wire segment and the light, and also to provide a fixing member to ensure the stability of the wire segment and the bulb. connection.
另外，该结构的串灯仅适用于一串采用单线串联的形式形成电回路的串灯，即多个灯体之间用导线段相互串联的情况。若需要实现多串并联在一起的串灯或者多个灯体并联的串灯，则需要采用导线段将单个灯体或串灯连接至电源正极线和电源负极线，布线繁杂，容易出错。In addition, the string lamp of the structure is only applicable to a series of string lamps which form an electric circuit in a single-line series connection, that is, a case where a plurality of lamp bodies are connected in series with each other. If it is necessary to realize a plurality of strings of strings connected in parallel or a plurality of strings connected in parallel, it is necessary to use a wire segment to connect a single lamp body or a string lamp to the positive line of the power source and the negative line of the power source, and the wiring is complicated and error-prone.

如图4至图7所示，为另一实施例中的串灯的结构示意图。本实施例的串 灯与实施例1的串灯的结构基本相同，二者的主要区别在于灯体还包括用于固定导线段的固定座5。灯壳2套设于固定座5的外周，优选地，固定座5收容于灯壳2的第二收容部22中。4 to 7 are schematic structural views of a string lamp in another embodiment. String of this embodiment The lamp has substantially the same structure as the string lamp of Embodiment 1, and the main difference between the two is that the lamp body further includes a fixing base 5 for fixing the wire segment. The lamp housing 2 is sleeved on the outer circumference of the fixing base 5 . Preferably, the fixing base 5 is received in the second receiving portion 22 of the lamp housing 2 .
固定座5包括圆环状的固定环52和从固定环52的内周向上延伸而出的固定件51。固定件51包括围成中空圆筒状的多个固定片511，相邻的固定片511之间隔着一定间隙。可以理解地，在其他实施例中，固定件51也能够形成为一体成型的圆筒状。The fixing base 5 includes an annular fixing ring 52 and a fixing member 51 extending upward from the inner circumference of the fixing ring 52. The fixing member 51 includes a plurality of fixing pieces 511 which are surrounded by a hollow cylindrical shape, and the adjacent fixing pieces 511 are spaced apart by a certain gap. It can be understood that in other embodiments, the fixing member 51 can also be formed into an integrally formed cylindrical shape.
