Network connector

Network connector

This creation is about an innovative structure of the network connector, which uses the voltage balance on the gold pin to cancel the noise.

The network connector, the most common RJ 45, is used to connect the network cable plug to achieve data transmission. Generally, the network connector has eight gold pins 92 extending from the circuit board 91. Refer to the first figure, which is electrically connected to the network cable plug. For further information, refer to the second figure, which is a schematic diagram of the gold pin layout, where A1 is the contact area between the gold pin and the plug, and A2 is the noise sensing length, and A3 is the circuit board circuit connection and compensation area; in the order of eight Among the gold needles, the most frequent interference is the third to sixth gold pins. Because the fourth gold pin is a negative charge signal source, and the fifth gold pin is a positive charge signal source, the third gold pin is induced to be negatively charged. According to the news, the sixth gold needle was induced to have positive charge noise, resulting in poor transmission characteristics.

In order to solve this interference problem, the PCB layout design is generally used to improve the interference effect, but the gold pin design is not improved. As a result, excessive interference noise voltage is generated at the gold pin, which can only rely on the circuit board circuit. It is used to balance the voltage to cancel the noise, but the cancellation ability is often insufficient, and further improvement is needed.

The author has studied the shortcomings of the general technology in many ways, and improved the gold pin design of the network connector. The principle of voltage balance to cancel the noise is applied to the gold pin design, and the purpose is to immediately carry out the positive and negative charge of the noise interference at the gold pin. Cancellation, that is, the action of canceling the noise on the gold pin in advance, and the circuit board only needs a little balance compensation, which can greatly reduce the noise and improve the transmission characteristics of the network connector.

The network connector provided by this creation is an insulating base. A socket is provided in the front of the insulating base for inserting the network cable plug, and a gold pin module is set in the insulating base. The gold pin module has eight gold pins, which extend from a circuit board; the ends of the gold pins away from the circuit board are arranged in the above-mentioned jacks in an order of 1-8 to form a contact area electrically connected to the network cable plug. Among them, the fourth and fifth gold pins cross between the contact area and the circuit board, so that the positive and negative charges caused by noise interference formed between the cross point and the circuit board are offset, so as to improve the transmission characteristics.

According to the network connector provided by this creation, according to the test, the noise can be reduced by an average of 10dB compared with the conventional gold-pin parallel network connector.

Hereinafter, the structural features and use effects of this creation will be explained in detail based on the embodiments shown in the drawings.

Please refer to the third and fourth figures. The creative network connector 1 has at least an insulating base 20 and a gold pin module 30.

A jack 21 for inserting a network cable plug is provided in the front of the insulating base 20, and a gold pin module 30 is provided in the insulating base 20.

The gold pin module 30 has eight gold pins 31, numbered P1 to P8, and each gold pin 31 extends from a circuit board 32, as shown in the third and fifth figures. A plurality of pierced terminals 33 are provided behind the circuit board 32, and the pierced terminals 33 are pierced into a plastic main body 34 of the terminal; the other elastic plate bracket 35 has an upward tilt bracket 351 with the end of the gold pin 31. The gold pins 31 are away from the end of the circuit board 32 and are arranged in the jack 21 of the insulating base 20 in the order of 1-8 to form a contact area electrically connected to the plug of the network cable.

The main purpose of this creation is to apply the principle of voltage balance to cancel the noise in the design of the gold pin 31. Refer to the sixth figure. The eight gold pins 31 extend from the circuit board 32. The area B1 is the contact area with the plug, and B2 is the noise. Induction length, and the 4th and 5th gold pins P4 and P5 cross between the contact area B1 and the circuit board 32, so that the noise electric positive and negative charge cancellation area B3 is formed in front of the circuit board 32, and the purpose is to immediately at the gold pin 31 The positive and negative charges of noise interference are cancelled, that is, the noise cancellation action is performed on the gold pin 31 in advance, while the circuit board 32 only performs a little balance compensation (circuit board circuit connection and compensation area B4), which can greatly reduce the noise. To improve the transmission characteristics of the network connector.

Please refer to the seventh figure, which is the result of the 250MHz component transmission interference test comparison between the cross-pin network connector (a2) and the general parallel gold pin network connector (a1) for this creation. The test result graph shows this The creation of an improved gold needle structure can greatly reduce noise, with an average of more than 10 dB.

In summary, this creation has improved the golden needle of the network connector, which indeed has better transmission characteristics than the conventional network, and fully meets the requirements of the patent. An application is filed in accordance with the law.
