Description

Connecting socket and plug based on network transmission 7-type and above high performance

Technical Field

The utility model relates to a connection socket and plug based on network transmission 7 types and above high performance belongs to internet wiring technical field.

Background

The 8 connection spring pieces of the existing RJ45(8P8C) module are all arranged at the bottom, so that the gap between each pair cannot be enlarged, and the signal crosstalk between each pair is difficult to reduce or eliminate, and for the communication channel, the connection performance at the module is the bottleneck point of the whole communication link, so that the existing RJ45 module is difficult to be improved to 7 types or higher. There are two existing solutions, one is based on RJ45(8P8C) module size, increasing the relative distance in which two pairs of PINs are placed on top to change the transmission line pair to improve the high frequency crosstalk problem; another approach is to separate the four communication channels and is not compatible with existing RJ45 form factor architectures, such as the terra series products.

Meanwhile, if the method is used for POE, the electromagnetic interference or the discharge possibility can be generated due to the small gap between the connecting elastic sheets.

The existing solution is as follows:

1. the eight spring plates are divided into an upper pair and a lower pair, and four pairs are thoroughly divided to form independent channels, so that the defect is that the size of the spring plates is completely different from that of a traditional RJ45 structure, the spring plates are incompatible with the traditional RJ structure and are not the common RJ45, and products adopting the solution are like TERA series.

2. The eight elastic sheets below the existing RJ45 are kept unchanged, a pair of elastic sheets is respectively added on two sides of the upper card port and is matched with a matched plug to connect two pairs of elastic sheets below and two pairs of elastic sheets above, so that the downward compatibility with the existing RJ45 is ensured, and meanwhile, the high-frequency transmission performance is improved. However, due to the fact that two pairs of elastic sheets are additionally arranged, when the plug is matched with a common plug, the insertion force is increased and is in a deformed state for a long time, and switching reliability is affected, and products adopting the solution are like GG45 series.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is compatible RJ45 and effectively prevent signal interference when how to improve net twine transmission performance.

In order to solve the technical problem, the technical scheme of the utility model is to provide a connection plug based on network transmission 7 types and above high performance, which comprises a rubber core main body and a contact piece, wherein the front surface of the rubber core main body is provided with M slots for installing the contact piece; the rubber core is characterized in that N slots for mounting contact pieces are arranged on one side surface or two side surfaces of the rubber core main body; and a wire groove for arranging a core wire is arranged at the bottom of each slot, and the contact pieces are conductive and transmit data and network signals.

Preferably, the back of the rubber core main body is provided with a buckle.

Preferably, M is 8; and the N is 2.

The utility model also provides a connection socket based on network transmission 7 types and above high performance, cooperates the above-mentioned connecting plug to use, its characterized in that, including the socket shell, the socket shell openly trompil, the inside bottom surface of socket shell is equipped with M shell fragments that electrically conduct and transmit data and network signal, the inside both sides face of socket shell is equipped with N shell fragments that electrically conduct and transmit data and network signal; the shell pieces are connected with core wires, and the core wires are led out from the back of the socket shell.

Preferably, M is 8; and the N is 2.

Preferably, a shielding shell is arranged outside the socket shell.

The utility model discloses the advantage lies in this technical scheme's high frequency high performance RJ45 connecting plug both guaranteed to be connected downward compatibility with current RJ45, has promoted high frequency connection performance simultaneously, can be applied to whole link performance to 7 types or higher, improves and switches the reliability. And the new structure can be conveniently and safely used for POE.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

Examples

This example RJ45 module increases

contact

4, 5 and contact 7, 8 two pairs of contact on the module side on present general RJ45 basis, when adaptation ordinary plug (present RJ45 general plug) satisfies general performance requirement, with following eight contact communication of current RJ45, if want to promote the performance, as long as with supporting socket 21 that uses, supporting socket 21 inside side is equipped with the

shell fragment

24, 25, 27, 28 corresponding to contact 4, 5, 7, 8, socket 21 bottom is the same with traditional RJ45 socket, is equipped with eight shell fragments and is used for the eight contact pieces that communicate RJ 45: at this moment, the following two pairs of

contact pieces

1, 2, 3 and 6 and the following two pairs of

contact pieces

4, 5, 7 and 8 on the side face are used for transmitting signals, so that the crosstalk between the contact pieces is greatly reduced, and the performance of the whole product is improved.
