[0031] The third conductive part 201 contacts the first conductive part 101 for electrical connection, and the fourth conductive part 202 contacts the second conductive part 102 for electrical connection.
[0032] The connector 2 includes a base 203 and an insert 204. The insert 204 is at least partially inserted into the connector 2, and the third conductive part 201 and the fourth conductive part 202 are fitted onto the insert.
[0033] The first conductive portion 101 and / or the second conductive portion 102 are arranged in a strip shape at intervals along the length direction of the substrate 203.
[0034] The insert 204 is a substrate with an insulating layer coated on it. The first conductive part 101 and the second conductive part 102 are copper foils and are fixed to the insulating layer at intervals.
[0035] The connector 2 is provided with a guide insert 205, which is in the same direction as the insert 204.
[0036] The guide insert 205 is provided with a limiting protrusion 206.
[0037] It also includes a power cord 207, which is at least partially located within the substrate 203 and electrically connected to the third conductive part 201 and the fourth conductive part 202 respectively. The power cord 207 and the third conductive part 201 and the fourth conductive part 202 may be soldered.
[0038] The fact that the first, second, third, and fourth conductive parts are strip-shaped can increase the stability of the contact.
[0039] Through the above technical solution, after the substrate of this utility model is inserted, the first conductive part 101 and the third conductive part 201, and the second conductive part 102 and the fourth conductive part 202 can be connected to achieve electrical conductivity, which increases the stability and speed of electrical connection and facilitates the electrical installation after the light strip is cut.
[0040] After the power line 207 is welded to the substrate 203, it is formed by plastic encapsulation.
[0041] A light strip includes the above-mentioned electrical connection structure and a flexible housing 3. An installation cavity 301 is formed in the flexible housing 3. A flexible circuit board 1 is disposed in the installation cavity 301. A plurality of light-emitting elements 302 are disposed on a first surface of the flexible circuit board 1. A second chamber 303 for inserting the connector 2 into the second surface and the bottom of the installation cavity 301 is formed.
[0042] The guide insert 205 at least partially abuts against the top of the mounting cavity 301;
[0043] The first conductive portion 101 and / or the second conductive portion 102 are arranged in a strip shape on the second side of the flexible circuit board 1;
[0044] The inner wall of the mounting cavity 301 is provided with at least one limiting part 304 for limiting the flexible circuit board 1. The limiting part 304 is at least partially an arc surface 305.

[0047] The bottom of the flexible circuit board 1 is electrically connected by conductive copper foil, and then formed by extrusion and coating with two-color silicone. The flexible circuit board 1 is electrically connected to a surface-mount light source, i.e., a light emitter 302, a surface-mount resistor 308, and conductive copper foil.
[0048] Because the base 203 is very thin, the outline of the connector 2 after insertion does not exceed the soft shell 3. The connector 2 is the same color as the light-emitting surface of the light strip, for example, white frosted, which looks beautiful and exquisite. It also has multiple wiring methods, such as straight wiring, right wiring, bottom wiring, and left wiring, which is convenient for installation.
