The first strip circuit board 200 and the second strip circuit board 400 are provided with circuits and LED chips, and the end portions are interconnected to splice a plurality of circuit boards, and for manufacturing convenience, in this embodiment, the male plug 100 includes a male socket 101, a positive pin 102, a negative pin 103, and a first connector 104. The male socket 101 is fixed at the end of the first bar-shaped circuit board 200; the positive pins 102 and the negative pins 103 are arranged on the male socket 101 at intervals side by side, and free ends of the positive pins and the negative pins extend out of the first bar-shaped circuit board 200 and are communicated with the first bar-shaped circuit board 200; a first connector 104 is disposed on the male socket 101 between the positive pin 102 and the negative pin 103. The female plug 300 includes a female socket 301, a positive jack 302, a negative jack 303, and a second connector 304. The female socket 301 is fixed at the end of the second bar circuit board 400; the positive jacks 302 and the negative jacks 303 are arranged in the female socket 301 side by side at intervals, are communicated with the second strip circuit board 400, and are respectively in inserting fit and conduction with the positive pins 102 and the negative pins 103; a second connector 304 is disposed on the female socket 301 between the positive and negative jacks 302 and 303 and mates with the first connector 104.

The upper surfaces of the male socket 101 and the female socket 301 are provided with a certain area, so that the plug is suitable for automatic SMT patch and is more convenient to manufacture; the conducting fingers realize electric connection.

When the male plug 100 and the female plug 300 of the embodiment are plugged, the first connecting piece 104 and the second connecting piece 304 are further arranged to be fixed for the second time, so that the interconnection and the separation are prevented during automatic production and feeding.

For convenience of manufacture and installation, preferably, the first connector 104 is a slot which is arranged on the male socket 101 and sinks, one end of the second connector 304 is fixed on the female socket 301, and the other end of the second connector is a hook which is matched with the slot. The clamping groove structure does not occupy the volume, and the detachable connection is realized by matching with the hook part.

Generally, the positive pin 102 and the negative pin 103 are made of metal and have high hardness, while the second connecting member 304 is made of an insulating elastic material and has a hardness that is easily broken, so that the portion of the second connecting member 304 extending out of the second strip circuit board 400 is shorter than the portion of the positive pin 102 and the negative pin 103 extending out of the first strip circuit board 200, so that the positive pin 102 and the negative pin 103 are partially fitted into the positive jack 302 and the negative jack 303, and then the second connecting member 304 is connected to the second connecting member 304.

Above-mentioned structure can form the horn mouth, plays the effect of guide contact pin, and first clamping piece 3023 can compress tightly the contact pin after being strutted, connects more reliably.

Further, the sharp end of the first clamping piece 3023 may cut the surface of the positive pin 102. The structure can enable the first clamping piece 3023 to be tightly connected with the positive pin 102, so as to bear larger current, enable the size of the pin to be small, and further enable the size of the male plug and the size of the female plug to be smaller.

Further preferably, the front end of the second jaw 3024 is bent outward to form a smooth grip surface on the inner side. The positive pin 102 is also good in conductivity, but the surface of the positive pin is not damaged, and the positive pin can be used continuously after being plugged.
