Description

Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector that is applied to the USB 3.0 specification and that is magnetically attracted to the housing.

With the increasing demand for convenient applications of electronic products, and thus the continuous attention of various manufacturers, in order to improve the competitiveness of electronic products, manufacturers must constantly strengthen and expand the functions of electronic products, so all kinds of electronic products are oriented In addition to being thin and light, the structure and transmission speed of the model are also required to be increased, so as to improve the convenience of the user in operation and use.

Since electrical connectors are used to connect signals between electronic products or between components in an electronic product, the importance of electrical connectors in electronic products is beyond words. How can manufacturers easily assemble electrical connectors during manufacturing? , to reduce the cost of assembly, while at the same time taking into account the effectiveness of electrical connectors, has become a competition among manufacturers.

In the electronic connector, the USB connector also has the biggest breakthrough. The USB (Universal Serial Bus) universal serial bus is a serial bus standard for connecting external devices. It is widely used on computers and is the most common. Specifications can also be used in set-top boxes and game consoles. Even many industrial instruments are connected to computers via USB. USB not only provides peripheral device data transmission, but also power supply. On-The-Go plug-and-play features are more. Can make portable devices straight Exchange data.

USB was originally a USB1.0 specification from the beginning, and its transmission speed was 1.5Mb/s. In 1998, the USB2.0 specification was introduced, and the transmission speed was increased to 12Mb/s, which is widely used in electronic products. In the current, the latest USB3.0 specification will increase the transmission speed to 5.0Gb/s, which is more than 10 times that of the USB2.0 specification. Since the speed is much higher than before, it has become a product promoted by various manufacturers in the future. .

Therefore, in the future of USB3.0 products, how to achieve the purpose of simple manufacturing of USB3.0 products has become a problem that manufacturers need to overcome, and the required connection of USB3.0 products. There are a large number of terminals, so how to increase the welding strength of the USB3.0 electrical connector soldered to the circuit board of the electronic product is also one of the problems that need to be overcome at present.

Only the terminals of the above USB connector can provide electrical contact, but the terminals are fixed to the circuit board by soldering, and then re-de-soldering and then re-welding, which causes inconvenience in the manufacturing process, in addition, due to The electronic device is designed to be light, thin, and short. Therefore, the USB connector used in the interior is also increasingly thin and light. If it is soldered and fixed to the circuit board only by the soldering portion of the terminal, the front end of the USB connector and the circuit board are The connection force may be insufficient. When the user docks with the docking connector due to improper angle or strength, the insulation of the USB connector may be warped or deformed, which may cause damage to the USB connector.

It can be seen that there are still many shortcomings in the above-mentioned conventional structure, which is not a good designer, but needs to be improved.

The creators of this case, in view of the shortcomings derived from the above-mentioned conventional structure, After improving and innovating, and after years of painstaking research, I finally successfully developed and completed this piece of electrical connector.

The purpose of this creation is to set the magnetic element at the front end of the insulating body so as to be magnetically attracted to the housing to achieve the purpose of fixing the insulating body.

In order to achieve the above object, the present invention comprises an insulating body and a flat conductive terminal and a resilient arm conductive terminal fixed on the insulating body; the contact portion of the flat conductive terminal and the elastic arm conductive terminal is exposed on the insulating body, and The connecting portion is exposed at the rear end of the insulating body to conform to the USB3.0 specification structure; a circuit board is provided for the insulating body, and a contact portion is disposed at a relative position of the overlapping portion; a housing is The insulative housing and the circuit board are covered by a cover member; a fixing member is attached to the insulative housing and the rear end of the circuit board and inserted into the housing; wherein the front end of the fixing member is provided with a pressing portion. When the fixing member is inserted into the casing, the pressing portion presses the overlapping portion of the flat conductive terminal and the elastic arm conductive terminal to electrically contact the contact portion of the circuit board; wherein the front end of the insulating body is accommodated The magnetic component allows the magnetic component to be magnetically attracted to the housing after the housing is covered by the insulating body to avoid warping deformation when the mating connector is mated with each other.
