Description

Receptacle Connectors and Terminals

The invention relates to an electrical connector, in particular to a socket connector and a terminal.

At present, electronic information products are becoming thinner and thinner, and due to the large amount of information, they need to meet the requirements of fast transmission speed. In electronic information products, electrical connectors usually play an important role in signal transmission. Since the volume of the electronic information product needs to be thinned, the height of the electrical connector must also be reduced to reduce the space occupied in the housing of the electronic information product.

How to reduce the height of the electrical connector, for example, the height is less than 5mm, and meet the electrical requirements of high-speed transmission, such as meeting the requirements of 112GHz transmission speed, still needs to be improved.

Therefore, one of the objectives of the present invention is to provide a low-profile socket connector that can meet the electrical requirements of high-speed transmission.

Therefore, another object of the present invention is to provide a low height and Terminals that can meet the electrical requirements of high-speed transmission.

Therefore, in some embodiments, the socket connector of the present invention includes an insulating shell and a plurality of terminals. The insulating case has a plurality of terminal grooves. The terminals are respectively arranged in the terminal grooves, and each terminal includes a base section, two elastic arms and a welding section. The base section has two ends and a connecting portion connecting the two ends, and the ends and the connecting portion jointly define a notch. The elastic arms are respectively bent upwards from the end portions and extend toward each other until they abut against each other, and then bend and extend obliquely upwards in the opposite direction. Each elastic arm has a bending portion connected to the corresponding end portion, a bending portion from the A main body extending from the main body, and a guide part extended from the main body, and a pressurizing part is formed at the junction of the bent part and the main body, and a pressure part is formed at the junction of the main body and the guide part. contact part. The welding section extends from the connecting portion of the base section and is located in the gap and spaced from the ends.

In some embodiments, the welding section is bent from the connecting portion and extends downward.

In some embodiments, the end of the soldering segment is covered by a solder ball.

The invention at least has the following effects: the socket connector as a whole can meet the requirements of miniaturization and low height and can meet the electrical requirements of high-speed transmission (112GHz).

Other features and effects of the present invention will be clearly presented in the implementation manner with reference to the drawings, wherein: Fig. 1 is a perspective view of an embodiment of the socket connector of the present invention; Fig. 2 is a perspective view of another perspective of this embodiment; Fig. 3 is a three-dimensional exploded view of this embodiment; Fig. 4 is along the IV-IV line in Fig. 1 A partial cross-sectional view taken; FIG. 5 is a perspective view of the terminal of this embodiment; and FIG. 6 is a perspective view of another perspective of the terminal of this embodiment

Referring to FIG. 1 to FIG. 3 , an embodiment of the socket connector of the present invention includes an insulating shell 1 and a plurality of terminals 2 . The insulating housing 1 has a plurality of terminal slots 11 for accommodating the terminals 2 respectively.

Referring to FIGS. 4 to 6 , each terminal 2 is disposed in one of the terminal grooves 11 and includes a base section 21 , two elastic arms 22 and a welding section 23 .

The base section 21 has two end portions 211 and a connection portion 212 connecting the two end portions 211 , and the end portions 211 and the connection portion 212 jointly define a notch 213 .

The elastic arms 22 are respectively bent upwards from opposite sides of the end portions 211 and extend toward each other until they abut against each other, and then are bent and extend obliquely upwards toward each other. Each elastic arm 22 has a curved portion 221 connected to the corresponding end portion 211, a main body portion 222 extending linearly from the curved portion 221, and a guiding portion 223 extended from the main body portion 222 by bending. The bending part 221 and the main body part 222 connect to form a pressurizing part 224 and in the main body A contact portion 225 is formed at the connection between the portion 222 and the guiding portion 223 . The contact portions 225 of the two elastic arms 22 lean against each other to have a pre-load force (pre-load force), so that when mating with terminals (not shown) of the mating connector, the contact portions 225 can clamp the mated terminals And produce a larger contact normal force (normal force). In this embodiment, the pressurizing portions 224 of the two elastic arms 22 are respectively bent and recessed inwardly, that is, the pressurizing portion 224 of each elastic arm 22 makes the bending portion 221 and the main body portion 222 A concave bend is formed between them toward the direction of the other elastic arm 22 , and the preload force formed when the contact portions 225 abut against each other can be strengthened by the pressurizing portion 224 .

The welding section 23 extends from the connection portion 212 of the base section 21 and is located in the notch 213 and spaced from the end portions 211 . In this embodiment, the soldering section 23 is bent and extends downwards from the connecting portion 212 , and the end of the soldering section 23 is covered by a solder ball S. As shown in FIG. Since the soldering segment 23 is located in the notch 213 and spaced from the ends 211 , the stress of the soldering segment 23 can be released to prevent the solder ball S from cracking.

In this embodiment, the height of the terminals 2 is less than 2 mm, and the overall height of the socket connector 100 is about 4.3 mm. With the aforementioned structural design of the terminal 2, the socket connector 100 as a whole can meet the requirements of miniaturization and low height, and can meet the electrical requirements of high-speed transmission (112 GHz).

But what is described above is only an embodiment of the present invention, and should not limit the scope of the present invention. All simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention. The scope covered by the invention patent Inside.
