Problems solved by technology

[0003] 1. The connection efficiency is low; the connecting wire needs to be initially fixed on the circuit board, such as using tweezers to press the soldering place, and then finally fixed by soldering;
[0004] 2. The reliability is poor; the connecting wire is fixed on the circuit board by welding, and the probability of false welding is relatively high, which reduces the reliability of the connection;
[0005] 3. High requirements for operators or equipment; it is necessary to accurately press the connecting wire to the welding place, and then weld and fix it, which has high requirements for the operator's vision and operation accuracy, and novices need a long time of training and practical training to meet the requirements

[0043] Clamping parts 21-22, the opposite clamping parts 21-22 are arranged on the side of the body, such as the upper side of the body, or the left and right sides, the gap between the clamping parts 21-2...

Embodiment 2

[0069] An application example of a circuit board in a lamp according to an embodiment of the present invention.

[0070] In this application example, the lights include:

[0071] Luminous parts, such as LED filaments, etc.;

[0072] a shell, the light-emitting element is arranged in the shell, and the shell transmits the light emitted by the light-emitting element;

[0073] One end of the hollow bearing is set inside the shell, and the other end extends out of the shell; the light-emitting element is fixed at one end of the bearing in the shell, and the bearing in the shell has a communication channel with the inside. The hole is closed at the other end of the carrier outside the shell, thereby isolating the inside and outside of the shell;

[0074] A first electrical connection wire, one end of the first electrical connection wire is connected to the light-emitting element, and the other end is connected to the drive circuit after passing through the carrier;

[0075] A dr...

Embodiment 3

[0096] The lamp according to the embodiment of the present invention is different from Embodiment 2 in that:

[0097] 1. A connecting piece is provided, the shell is connected to the lamp cap through the connecting piece, and the driving board is arranged in the connecting piece;

[0098] 2. Electrical connection unit: No need to set the first opening, the clamping part and the guide part protrude outward relative to the body, and the projection of the area surrounded by the guide part and the second opening on the horizontal plane completely falls within the projection of the notch on the horizontal plane; The part only needs to be used to connect the lower part of the first part and the second part, without the upper part; the width of the gap formed at the end of the clamping part away from the guide part is less than 0.5 times the outer diameter of the first connecting line, such as zero.

Abstract

The invention provides a circuit board, a lamp and a manufacturing method. The circuit board comprises a substrate, wherein an electric connection unit fixed on the substrate comprises a body, clamping parts and guide parts; the body is arranged oppositely and bears the clamping parts; the clamping parts are arranged oppositely and are arranged on the side part of the body; the width of a gap between the clamping parts is not greater than the outer diameter of a connecting line; the distance between the guide parts arranged oppositely is reduced from outside to inside; the connecting line is suitable for penetrating through an area between the guide parts and is clamped in the gap; the substrate is provided with a notch or a through hole; and the projection of the notch on a horizontal plane is overlapped with the projection of an area surrounded by the guide parts on the horizontal plane. The circuit board has the advantages of firm fixation, high efficiency and the like.

Description

technical field [0001] The invention relates to connecting wire fixing, in particular to a circuit board, a lamp and a manufacturing method. Background technique [0002] At present, in the electrical connection between the connecting wire and the circuit board, soldering is usually used. The disadvantages of this connection method are: [0003] 1. The connection efficiency is low; the connecting wire needs to be initially fixed on the circuit board, such as using tweezers to press the soldering place, and then finally fixed by soldering; [0004] 2. The reliability is poor; the connecting wire is fixed on the circuit board by welding, and the probability of false welding is relatively high, which reduces the reliability of the connection; [0005] 3. High requirements for operators or equipment; it is necessary to accurately press the connecting wire to the welding place, and then weld and fix it, which has high requirements for the operator's vision and operation accurac...
