Description

Electrical connector

The present invention relates to an electrical connector for an LED circuit substrate, and more particularly to an electrical connector that is disposed through an LED circuit substrate.

According to the fact that people can still operate normally at night and in dim weather, through the application of lighting fixtures, there can be sufficient light for illumination at night and in dim weather, and the most commonly used lamps for general lighting, such as early Light bulbs and fluorescent tubes are the most common and most widely used lighting fixtures. Lights from the lighting fixtures can be used to prevent activities and work during night or dark weather, but due to fluorescent tubes or The lamp has a short service life, is not easy to handle after disposal, and consumes a large amount of electricity. Some manufacturers have developed a power-saving bulb and a lamp to improve the design of the bulb, prolong the service life of the bulb or the lamp, and achieve energy saving. Purpose, but the power-saving bulb or tube still has a large volume, and it is quite inconvenient to recycle. The manufacturer has developed a light-emitting diode (LED) to form a bulb or a tube to provide more Lighting fixtures that are energy-saving and small in size and have a long service life have become the main lighting products currently on the market.

However, the above LED bulb or lamp tube assembly is arranged on the LED circuit substrate, and the LED driving circuit board is matched to control the current flowing through the LED to achieve or close to the value of the original design, and to stabilize or not be reduced or reduced. Power supply voltage, temperature, forward bias difference and other factors Influence, thereby obtaining the required luminosity, preventing the LED life from being shortened or damaged, and the LED driving circuit board and the LED circuit substrate are mounted in such a manner that the LED circuit substrate and the LED driving circuit board are connected by wire bonding or have a pre-prevention The LED circuit board with perforations is provided with an electrical connector for inserting the LED driving circuit board, and the electrical connector group is assembled on the LED circuit substrate by conventional techniques, which can be assembled by welding, which can be seen in the Republic of China. In the invention patent application No. 99139769, the LED, the connector, and the like disposed at a predetermined position on the upper surface of the LED package substrate described in the original text of the specification are welded, for example, using a reflow furnace. By this step, the connection portion of the contact member is soldered to the pad of the LED package substrate. Therefore, it is known that the welding and soldering connector is a conventional method in the industry.

However, the conventional electrical connector has the following disadvantages:

First, the welding method is used to assemble the electrical connector on the LED circuit substrate. When the electrical connector or the LED circuit substrate is opened or the soldering point on the substrate is in dimensional error, the electrical connector and the substrate are pressed to be easily formed after soldering. The force, in turn, makes it possible to have the electrical connector disconnected from the solder joint in the future.

2. When the electrical connector is to be assembled on the LED circuit board, the electrical connector must be mechanically or manually mounted to the LED circuit substrate, and then the LED driver circuit board is mounted after the solder is fixed to the connector. At least two or more assembly procedures are required.

Third, the conventional terminal design is too complicated, so that the terminal requires multiple processes to form it, so the increase of the process procedure is increased with respect to the time cost.

Therefore, how to solve the problems and shortcomings of the use, that is, the relevant manufacturers in this industry are eager to study the direction of improvement.

Therefore, the new creators, in view of the problems and shortcomings of the conventional electrical connectors, collected the relevant materials through multi-party evaluation and consideration, and continuously tried and modified the years of R&D experience in the industry to design such electrical connectors. A new type is born.

The main purpose of the present invention is to provide a positioning elastic arm group for positioning the insulating body on the outer surface of the base body with the stopper portion on the outer surface of the base body when the electrical connector is mounted on the LED circuit board, and the positioning head group is matched with the set head. The side surface extends in the lateral direction so that the head can abut against the mounting surface of the LED circuit board, and after the positioning elastic arm group passes through the predetermined perforation, the difference of the stopping portion abuts against the substrate perforation wall surface and the hole wall surface and the opposite surface The formed corners enable the electrical connector to be stably mounted on the LED circuit substrate, and the terminal groups in the electrical connector are also electrically connected to the connection contacts on the circuit board, which is different from the electrical connection. After passing through the perforation, the circuit is electrically connected in a fixed manner to reduce the assembly process and assembly time.

Another main purpose of the present invention is that the electrical connector and the circuit board have a certain tolerance value or dimensional misalignment, so that the positioning elastic arm of the outer surface of the seat body is bent and extended toward the head, and when the size is out of alignment for the foregoing reasons. The relative size and position of the electrical connector and the LED circuit substrate can be corrected by positioning the elastic buffer space formed by the reverse bending of the elastic arm.

The secondary purpose of this creation is that the terminal structure is simple and easy to install with the electrical connector structure, and a preset number of terminals can be inserted as needed to save time in the process flow and the assembly process.
