Abstract
The invention discloses a connector for a light-emitting diode (LED) flexible circuit board. The two ends of the connector are connected in parallel with the LED flexible circuit board. The connector is provided with an upper cover and a base. Two fixing clamps are arranged at the inner bottom of the upper cover. Through holes and clamping stopping parts are arranged on copper sheets which are shaped like a Chinese character 'Gong'. The base is used for bearing the copper sheets. A 'Z'-shaped step is arranged at each of the two symmetrical ends of the base without lateral surfaces. Elastic inverted buckles and a partition part are arranged between the two 'Z'-shaped steps. The LED flexible circuit board is clamped by the copper sheets, and the upper cover fastens the base and tightly presses the copper sheets, so that the LED flexible circuit board is pressed to form the 'Z'-shaped steps. A requirement for the over-current of higher than 5A is met, tensile force of more than 5 kilograms is obtained, and the connector has certain pre-tightening force, and is convenient to mount.
Description
[affiliated technical field]
The present invention relates to a kind of connector, relate in particular to a kind of LED flexible circuit board connector.
[background technology]
Fast development along with the LED technology; Use LED as light source and be loaded in the LED flexible light band that is made on the flexible PCB be widely used in living with industry in the middle of every field, places of throwing light on such as advertisement and identifier edge light, contour of building illumination, tree crown, corridor, the illumination of indoor smallpox, park decorative lighting for example.Yet along with the extensive utilization of LED flexible light band, its length requirement is also more and more longer, for example 20 meters, and 50 meters, 100 meters, in addition longer.But the disposable LED flexible light band of making length like this has certain difficulty for the equipment that uses in the present industry, therefore in order to accomplish length requirement, generally through connector many LED flexible light bands is electrically connected each other, realizes length requirement.
In the market a kind of connector for example; One metal clips is fixedly attached to insulating body and outstanding insulating body surface two touches face; One of them touches the copper foil electrode electrically contact mutually on face and the LED flexible light band; Another touches the copper foil electrode electrically contact mutually on face and another LED flexible light band, adopts this kind connector to realize being electrically conducted each other of many LED flexible light bands.Because only through being electrically conducted an of contact and LED flexible light band, the conductive contact surfaces of one side junction is too small, can't satisfy the overcurrent greater than 2A for this kind connector, for example can't satisfy overcurrent is the LED flexible light band of 5A; Ought use on the other hand greater than 2 kilograms pulling force connector and LED flexible light band are done the time spent, easy quilt draws back, and causes the LED flexible light band to separate with connector.
For example, another kind of connector, and connect the LED flexible light band, the formation conducting portion is exposed in the conducting wire of LED flexible light band one end; Connector is provided with the jackended that can insert the LED flexible light band and cooperate with the flexible light band shape and structure, and its set inside has the spring-like connector, and the spring-like connector is provided with resilient clamp portion.Concrete operations are: the conducting portion of the LED flexible light band jackended from connector is inserted between the resilient clamp portion of spring connector, clamp the conducting portion of LED flexible light band with resilient clamp portion, realization is electrically conducted many LED flexible light bands mutually.The shortcoming of this kind connector is to have only through resilient clamp portion clamps the LED flexible light band, and through the elastic force clamping, stretching resistance is too small, can't bear bigger pulling force each other; When for a long time in suspension during work because the influence of gravity and other factors causes LED flexible light band and connector to break away from, so cause the flexible light band inefficacy, can't operate as normal.
