Description

Electric connector

This creation is about an electrical connector, especially an electrical connector that is specially provided with fixed terminals and soldered to a circuit board to improve the strength and flatness after soldering.

As people's demand for convenient application of electronic products becomes more and more obvious, and then they continue to pay attention to various manufacturers. In order to improve the competitiveness of electronic products, manufacturers must continue to strengthen and expand the functions of electronic products. In addition to being thin, light and short, its structure and transmission speed also need to be continuously increased, so as to improve user convenience in operation.

Because electrical connectors are used to connect signals between electronic products or between components in electronic products, the importance of electrical connectors on electronic products is beyond words. How manufacturers can easily structure electrical connectors during manufacture Assembly, reducing assembly costs, while taking into account the effectiveness of the electrical connector structure, has become a place of successive competition among various manufacturers.

Among the electronic connectors, the USB connector 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 popular. Universal specifications can also be used in set-top boxes and game consoles, and even many industrial instruments are also connected to the computer via USB. USB can not only provide data transmission of peripheral equipment, but also supply power. On-The-Go plug and play Features make portable devices straight Then exchange data.

From the beginning, USB was the USB 1.0 specification with a transmission speed of 1.5 Mb / s. In 1998, the USB 2.0 specification was introduced and the transmission speed was increased to 12 Mb / s. This specification is widely used in electronic products. Medium, and the latest USB 3.0 specification has increased the transmission speed to 5.0 Gb / s, which is more than 10 times the USB 2.0 specification. Because the speed is much higher than in the past, it has become a product promoted by various manufacturers in the future. .

Therefore, under the circumstances that the USB3.0 specification products can be expected in the future, how to make USB3.0 products easy to manufacture and can be applied to thin, light and short electronic devices has become a problem that manufacturers need to overcome, and it is due to USB3. The 0 specification product requires a larger number of connection terminals. Therefore, how to increase the connection strength between the conductive terminals of the electrical connector and the body, and also can be applied to the circuit boards of different electronic devices is a problem that needs to be overcome. One.

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

In view of various shortcomings derived from the conventional structure described above, the creator of this case was eager to improve and innovate. After years of painstaking research, he finally successfully developed this electrical connector.

The purpose of this creation is to enable the electrical connector to be firmly soldered to the circuit board through the arrangement of the fixed terminals.

Another purpose of this creation is to prevent the warping and deformation of the front end of the insulating body when the insulating body is soldered to the circuit board through the arrangement of the fixed terminals.

In order to achieve the above purpose, the electrical connector of this creation includes an insulating body, The insulating body is provided with a terminal accommodating groove; a plurality of elastic terminals include a fixing portion fixed on the insulating body and contact portions and welding portions extending from both ends of the fixing portion and exposed on the insulating body, respectively; The terminal includes a fixed portion fixed on the insulating body, and a flat plate contact portion extending from both ends of the fixed portion and exposed on the insulating body, and welding; two sides of the insulating body are respectively provided with a fixed terminal, which includes a setting A fixed part in the insulating body and a welding part exposed on the bottom surface of the insulating body.

Compared with the conventional connector, the difference between this creation and the conventional connector is that the conventional connector is not provided with a fixed terminal, so when it is to be soldered to a circuit board, the front end of the insulating body of the connector will be warped and deformed due to heat. This makes the connector unable to fit flatly on the circuit board. In contrast, the insulated body of the electrical connector of this creation is provided with fixed terminals on both sides, and the front end of the fixed terminal is provided with a soldering portion exposed on the bottom surface of the insulated body, so through the fixing The terminal soldering part is provided to firmly attach the front end of the insulating body to the circuit board, and avoid the insulating body from being deformed due to heat.

In order to achieve the above purpose, there is a most appropriate distance between the fixed terminal welding portion and the welding portion of the elastic terminal and the flat terminal. The most suitable distance is the center position of the fixed terminal welding portion and the elastic terminal and the flat terminal welding portion. The center position distance is between 8 and 11mm.

In order to make the above and other objects, features, and advantages of this creation more comprehensible, the following describes the preferred embodiments in detail with the accompanying drawings, as follows.

Please refer to the first to seventh figures. The electrical connector of this creation includes: an insulating body 1, which is substantially a rectangular body, and includes a base portion 11 and a flat plate portion extending from the base portion 11. 12, the plate portion 12 is provided with a plurality of terminal accommodation grooves 13 at a position near the base portion 11, and the terminal accommodation grooves 13 are arranged in front and rear rows, which are the first four and the last five in terms of quantity. The number is set so that it conforms to the USB 3.0 specification arrangement, and the rear terminal receiving grooves 13 are penetrated through the flat plate portion 12, and the front side of the flat plate portion 12 is provided with an opening 14 respectively, and the opening 14 is The two sides are provided correspondingly; the plurality of elastic terminals 2 are arranged in the terminal receiving grooves 13 in the rear row, so the number is five, and includes a fixing portion 21 and a self-fixing portion 21 fixed on the insulating body 1 The two ends respectively extend and are exposed to the contact portion 22 and the welding portion 23 of the insulating body 1, wherein the contact portion 22 can be elastically reciprocated, so that when it is mated with the mating connector, it can be elastically reciprocated, and the contact The part 22 is located above the terminal receiving groove 13. The soldering portion 23 is exposed outside the rear end of the insulating body 1, more specifically, the rear end of the base portion 11 of the insulating body 1 is exposed for soldering to a circuit board; a plurality of flat plate terminals 3 are provided in the front row. The number of the terminal accommodating grooves 13 is four, which includes the fixing portion 31 and the self-fixing portion 31 fixed on the insulating body 1. The two ends respectively extend and are exposed to the flat plate contact portion 32 and the welding portion 33 of the insulating body 1, wherein the flat plate contact portion 32 is located on the terminal receiving groove 13 and has a substantially coplanar structure with the insulating body 1, and the welding portion 33 is exposed at the rear end of the base 11 of the insulating body 1 for soldering to a circuit board; the welding portion 23 of the above-mentioned elastic terminal 2 and the welding portion 33 of the flat terminal 3 are exposed at the rear end of the insulating body 1, if viewed from a top view The soldering portions 22 and 33 are substantially on the same line.
