The RJ45 is a connector for an information socket (i.e., a communication outlet) in a wiring system, and the connector is composed of a plug (a connector, a crystal plug) and a socket (a module), wherein the plug has 8 grooves and 8 contacts. RJ is an abbreviation for registered jack meaning "registered jack". RJ45 is composed of a plug and a socket, and a connector composed of these two components is connected between wires to achieve electrical continuity of the wires. The core of the RJ45 module is a modular jack. The gold plated lead or socket hole can maintain stable and reliable electrical connection with the modularized socket spring. The electrical contact is further enhanced with the insertion of the plug due to the friction between the spring and the receptacle. The jack body design employs an integral locking mechanism such that when the modular plug is inserted, maximum pull-out strength is produced outside the interface of the plug and jack.

Wisdom blackboard among the prior art, after accomplishing the installation of electric connecting wire 10, in order to carry on spacingly to electric connecting wire 10, need install the fastener respectively at the back of the main screen body and the back of the vice screen body, wire 11 passes the centre gripping space in the middle of the fastener, but the fastener only has the restriction to the lateral movement of wire 11, when the pulling force acted on electric connecting wire 10, still there is some pulling force to transmit to the connector along the extending direction of wire 11, in other words, adopt this kind of fastener to be spacing to wire 11, lead to the connector of electric connecting wire 10 and the connector support of the screen body to draw intensity on the small side, the connector of the screen body is hindered by pulling easily.

In the intelligent blackboard of the embodiment, the first wire cover 201 is clamped with the first fixing sleeve 1014, so that the transmission of pulling force along the wire 11 can be prevented, and the pulling strength of the first electric connecting wire 101 when being connected with the main screen body is improved through the first wire cover 201; the second wire cover 202 is clamped with the second fixing sleeve 1024, so that the transmission of pulling force along the wire 11 can be prevented, the pulling strength of the second electrical connection wire 102 when being connected with the main screen body is improved through the second wire cover 202, and the pulling strength of the second electrical connection wire 102 when being connected with the auxiliary screen body is improved through the second wire cover 202. Meanwhile, the RJ45 male and female connectors are used as the first and second docking connectors 1013 and 1023, so that the pull strength between the first and second electrical connection wires 101 and 102 is improved. So, no matter drag electric connection line 10 at the in-process of wisdom blackboard installation, still overhaul wisdom blackboard, drag electric connection line 10 when dismantling the vice screen body of removal, the connector in each position is difficult to torn.

Moreover, the first wire cover 201 covers the first wiring port 3101, the second wire cover 202 covers the second wiring port 4101, and a large wire cover 20 is not required to be specially installed behind the main screen body and the auxiliary screen body for dust prevention, so that the structure of the intelligent blackboard is simplified, and the assembly efficiency and the maintenance efficiency of the intelligent blackboard are improved.
