Technical Field

The present disclosure relates to electrical connectors, and particularly to an electrical connector for an LED light strip.

Background

As shown in fig. 1 and 2, the conventional LED lamp strip connected with 220V mains supply is a patch type LED flexible lamp strip, which comprises a core wire 1, a transparent coating layer 2 for coating the core wire 1, a plurality of unit flexible PCB boards 3 and a plurality of patch type LED chips 4 arranged on the flexible PCB boards 3, wherein the core wire 1 is provided with a containing channel 11 along the length direction thereof, the flexible PCB boards 3 are sequentially arranged in the containing channel 11, gaps are reserved between adjacent circuit boards, the side wall 15 of the core wire 1 is sequentially provided with a through hole 12, the patch type LED chips 4 are accommodated in the through hole 12, and the core wire 1 is provided with an accommodating groove 13 for accommodating the flexible PCB boards 3 in the core wire 1. Two parallel connecting wires (5) used for being electrically connected with an external power supply are buried in the core wire (1), and the connecting wires (5) are connected with the lead wires (6) at the end part of the flexible PCB (3) to realize the electrical connection of the connecting wires (5) and the flexible PCB (3). In engineering installation, in order to realize the electric connection between the connecting wire (5) and an external power supply, one end of a pair of metal pins 7 is inserted into the core wire to be electrically connected with the connecting wire 5, and the other end of the metal pins 7 is inserted into a jack of an electric connector (socket). In general, the distance between two parallel connection wires (5) in a light strip is different due to the size of the LED chip 4, and the planar size of the LED chip is usually the size of the LED chip, for example, the size of a 5050 type LED chip (length and width is 5 mm) is larger than the size of a 3528 type LED chip (length is 3.5 mm and width is 2.8 mm), so that the distance between two parallel connection wires of a 5050 type LED light strip is larger than that of a 3528 type LED light strip, and therefore, in reality, different types of LED light strips need to be plugged with electrical connectors with different plug jack distances for plugging pins 7, which results in frequent errors of workers in matching, and therefore, it is necessary to design an electrical connector suitable for different types of LED light strips.
