Copper wire rivet for LED lamp strip and copper wire riveting process

Abstract

The invention relates to the technical field of electrics, in particular to a copper wire rivet for an LED light bar and a copper wire riveting process. The copper wire rivet for the LED light bar comprises a rivet cap, the bottom face of the rivet cap is provided with a rivet head which is perpendicular to the rivet cap and extends downwards, and the rivet head is of a columnar structure. The middle section of the rivet head is provided with a prefabricated part formed by reducing the columnar surface diameter. The copper wire riveting process for the LED light bar adopts the copper wire rivet for the LED light bar, and comprises the following steps that (1) a conductive copper wire with an insulating sheath is prefabricated on the back surface of a substrate of the LED light bar along the length direction; (2) the rivet is nailed in from the front face of the substrate of the LED light bar, and the rivet head of the rivet penetrates through the conductive copper wire from the back surface of the substrate; and (3) the rivet is stamped axially from the rivet cap of the rivet to enable the rivet head to generate stress deformation taking the prefabricated part as a base point to form a riveting structure so as to realize circuit connection between the conductive copper wire and the LED light bar.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a copper wire rivet and a copper wire riveting process for an LED light bar. Background technique [0002] LED light strip is a kind of lighting product of LED series. It adopts a long strip substrate, and packages high-brightness LEDs on the front of the substrate as the light source. Usually, one or more LEDs are used as a circuit unit, which can be truncated according to the required length. Access without destroying the circuit unit. [0003] In order to connect the circuit units on multiple LED strips in series or in parallel, conductive copper wires are arranged on the back of the substrate to construct a series or parallel circuit, and rivets are used to penetrate the conductive copper wires from the circuit units on the front of the substrate to the back of the substrate , and then carry out axial punching on the rivet, so that the head of the rivet is bent to form a...

AI Technical Summary

Problems solved by technology

If the nail head 2' is bent too close to the nail cap 1', the riveting will be too tight, and the conductive copper wire and LED light bar will be easily broken; if the nail head 2' is bent too far away from the nail cap 1', it will cause If the riveting is too loose, it is easy to cause poor conductivity
