Description

Press fit electrical connector

The invention relates to a connector, especially a press-fit electrical connector.

Existing electrical connectors are mainly soldered to the circuit board through the female end or socket, and then the male end or plug is connected to the female end and socket to achieve the purpose of electrical connection.

However, since the receptacle or socket must be disposed on the circuit board through soldering, it is difficult to disassemble and replace the receptacle or socket from the circuit board without desoldering. Especially for consumers, they usually do not have the technology to desolder. In addition, the current connector specifications are also miniaturized. Therefore, the pins are relatively precise in soldering, and desoldering is not easy.

In view of this, in order to improve and solve the above-mentioned deficiencies, the author of this article has devoted himself to research and combined with the application of academic theories, and finally proposed a creation that is reasonably designed and effectively improves the above-mentioned deficiencies.

The main purpose of this invention is to provide a press-fit electrical connector that can maintain a normal electrical connection state between the electrical connector and the circuit board without welding, so that ordinary people can make it at any time. Replace or update.

In order to achieve the above purpose, the present invention provides a press-fit electrical connector for being installed on a circuit board; the electrical connector includes a connecting body and a fixing component; the connecting body has an insulator, and is located on the insulator. There are a plurality of terminals inside, and each terminal has a terminal foot extending from the insulator; the fixing component is used to fix the connecting body towards the circuit board, and the fixing component has at least one fixing part fixed on the circuit board; Each terminal pin is provided with a buffer pad in contact with it so that each terminal pin is in contact with the circuit board.

As shown in Figure 5, after the electrical connector 1 is placed on the circuit board 2, the fixing component 11 can be pressed against the above-mentioned connecting body 10 and fixed toward the circuit board 2; in the embodiment of the present invention, , the insulator 100 of the connection body 10 is provided with a pin seat 100b toward the terminal pins 101a, and the pin seat 100b can accommodate the above-mentioned buffer pad 103 inside it, and at the same time, it is supported by the fixing component 11 The portion 110 presses the pin base 100b toward the circuit board 2 so that the cushion pad 103 contacts each terminal pin 101a so that each terminal pin 101a can make contact with the conductive portion 21 of the circuit board 2 . Furthermore, a convex portion 103a can be formed on the buffer pad 103 corresponding to each terminal pin 101a to ensure alignment with each terminal pin 101a.

Next, as shown in FIGS. 6 and 7 , the fixing component 111 a is penetrated into the fixing part 111 and fixed on the circuit board 2 , thereby forcing the supporting part 110 of the fixing component 11 to pass through the cushion pad 103 to separate each terminal pin 101 a Against the conductive portion 21 of the circuit board 2, the electrical connection and normal use of the electrical connector 1 and the circuit board 2 can be maintained without soldering, and at the same time, the terminal pins 101a of the connector can be prevented from being deformed.
