Electrical connector

The present invention provides an electrical connector, in particular, a stopper protruding from a lower wall surface of a pedestal and a notch and a connecting piece of a sleeve terminal, which can simplify the structure of the sleeve terminal, and is stable and not easy to be offset. Or the effect of shaking.

According to the rapid development of electronic technology and multimedia information, electronic devices such as notebook computers, tablet computers, and mobile phones have become commonplace in all corners of society, and the design of electronic devices tends to be light and thin. Short and small, the structure of the electronic components on the internal circuit board of the electronic device must be reduced and more precise, and the overall structural strength needs to be strengthened to meet the current development trend.

In general, electronic devices generally use connectors to achieve connection with a circuit board, and most of the connectors can be provided with cables therein, and are connected to a plurality of signal terminals or power terminals inside the connector for connection. Another mating connector transmits signals or power through the board to the control circuit. As the connector becomes smaller and smaller, various types of connectors, such as probe-type (Pogo Pin) connectors, have been developed. As shown in the sixth and seventh figures, respectively, the perspective view and the side cross-sectional view of the conventional electrical connector are respectively arranged in the receiving slot A1 of the insulating housing A to accommodate the metal probe B and the conductive base. C and compression spring D, and the metal probe B is manufactured by turning processing, and has a wearable outer casing A1 The contact end B1 and the annular abutting end B2 having a large outer diameter, and the conductive base C has a joint portion C1 connectable to the circuit board, and a side wall C2 extends upward from both sides of the joint portion C1. Further, the arm C3 is bent and bent downward. However, the compression spring D is disposed between the two side walls C2 of the conductive seat C, and the upper end of the compression spring D abuts against the abutting end B2 of the metal probe B, and The lower end is in contact with the conductive body C.

When the contact end B1 of the metal probe B is pressed into the insulating housing A by an external force, it can be elastically deformed by the compression spring D, and by the abutting end B2 of the metal probe B and The arm C3 on the two side walls C2 of the conductive seat C is in contact with each other, so that the electrical connection can be achieved. However, the metal probe B is manufactured by a turning method, which not only causes the annular abutting end B2 to be processed. It is quite time-consuming and extremely inconvenient and difficult, so that the cost of materials and manufacturing cannot be effectively reduced. However, in the process of processing metal probe B, structural defects and damages are easily generated, and the effect of overall electrical contact is affected. Those who are still in the industry are redesigned to effectively solve them.

Therefore, the creators have designed and produced such electricity based on the problems and lacks in the use of the conventional electrical connectors, and the collection of relevant materials through various assessments and considerations, and the continuous trial and modification of the years of research and development experience in this industry. The new connector was born.

The main purpose of the creation is that the inside of the base is provided with a plurality of passages for receiving the sleeve terminal, the clamp seat and the spring which are integrally formed by bending and bending the metal sheet body, and the block protruding from the lower wall surface of the passage is used for the expansion and contraction. The notch and the connecting piece are set on the lower surface of the sleeve terminal, so that when the sleeve terminal is not pushed up, the blocking end of the connecting piece near the notch will resist the stopper, and the sleeve will not be taken out of the channel, so that the sleeve The terminal can be straight in the overall structure of the electrical connector Shape design to achieve a simplified structure and high stability.
