Description

Anti-pulling crystal head

Technical Field

The utility model relates to a computer technology field, concretely relates to quartzy head.

Background

The comprehensive wiring system is popularized along with the development of network technology, is an open star-level structure system, and finally, ideally, the data transmission of equipment in a building or a park is borne by a medium and an interface. With the development of ethernet technology, from the first 10M, 100M, to 1000M, 10G, integrated wiring systems have become essential infrastructure for intelligent systems in buildings, and RJ-45 jacks and plugs have become standard ports for network devices.

A standard RJ-45 connector consists of a plug and a socket, the two components of the connector being connected between wires to achieve electrical continuity of the wires.

The RJ-45 socket and the RJ-45 plug take the open principle of the comprehensive wiring system, the physical safety is extremely low, and the wrong plugging and unplugging events are frequent, so that the economic loss caused by the wrong plugging and unplugging events is very large.

The core of the RJ-45 module is a modular jack, and a gold plated wire or jack maintains a stable and reliable electrical connection with a modular jack dome. 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. The wiring module on the RJ-45 module is connected with the twisted pair through a U-shaped wiring groove, and the RJ-45 module can be fixed on an information outlet device such as a panel by a locking elastic sheet.

An RJ-45 plug is a plastic connector that can be inserted in a fixed direction and automatically prevents it from falling off, commonly known as a "crystal plug", and the term of art is an RJ-45 connector (RJ-45 is a network interface specification, and similarly, an RJ-11 interface, which is a commonly used "telephone interface" for connecting a telephone line). It is called a "crystal head" because of its glittering and translucent appearance. The crystal head is suitable for field termination of equipment or horizontal subsystems, and the shell material adopts high-density polyethylene. Two ends of each twisted pair are connected with the network card and the concentrator (or the exchanger) by installing crystal heads.

The standard RJ-45 plug consists of a base body 3, a reed 4, an inverted card 5 and an inverted card spring sheet 6; generally, the end of the base body that is connected to the spring (or the end that is inserted into the socket during use) is called the front end, and the other end (or the end that is left outside the socket during use) is the back end; the reverse clamping elastic sheet extends backwards and upwards in an inclined way from the connecting point at the front end of the base body; the reverse card 5 is positioned on the reverse card elastic sheet 6; the reverse card 5 is matched with a bayonet on a standard RJ-45 socket.

The crystal head mainly adopts the anti-withdrawing aspect that a reverse clamping elastic sheet is arranged on the crystal head, the reverse clamping elastic sheet is arranged obliquely, the reverse clamping elastic sheet bounces when a network cable is inserted, the reverse clamping 5 is automatically clamped into a bayonet in the interface, and when the network cable is drawn out, the reverse clamping elastic sheet is firstly pressed down and then drawn out

The service life standard of the reverse card requires 750 times of plugging and unplugging, and in the actual use process, the reverse card is very easy to break due to various reasons on site, even if the reverse card is not broken, the elasticity of the reverse card elastic sheet is lost, and the function of preventing automatic falling is lost.

Disclosure of Invention

The anti-pulling crystal plug is characterized in that a special tool lock is added by redesigning an inverted card on the basis of a standard RJ-45 connector, so that an RJ-45 plug becomes an anti-drop and anti-unauthorized management object, the physical safety of a comprehensive wiring system is improved, and the system safety of a private network in a data center is improved.

The anti-pulling crystal head consists of a base body, a reed, an inverted card elastic sheet, a lock hole base, an unlocking hole and a key, wherein the lock hole base is positioned at the upper part of the rear end of the base body, and the unlocking hole is formed in the lock hole base and is communicated with the front part and the rear part; one end of the reverse clamping elastic sheet is fixedly connected with the upper surface of the rear end of the base body, the other part of the reverse clamping elastic sheet extends forwards and obliquely upwards, and a reverse clamp is arranged on the reverse clamping elastic sheet; the opening of the unlocking hole in front of the lock hole base is higher than the upper surface of the inverted card spring sheet adjacent to the opening; the key is matched with the unlocking hole, and the key can pass through the unlocking hole and downwards press the inverted clip spring.

In the anti-pulling crystal head, the lock hole base is fixedly connected with the base body or integrated with the base body.

The anti-pulling crystal head, the keyhole base and the key are one of 12 colors related to color management in the TIA/EIA606 standard.

In the anti-pulling crystal head, the number of the unlocking holes is 1 or more than 1.

Advantageous effects

When the anti-pulling RJ-45 plug is inserted into the standard RJ-45 socket, the reverse clamp is pressed into the RJ-45 socket along the reverse clamp cambered surface and then recovered, and self-locking is completed; when the reverse clamping elastic sheet is not extruded by external force, the anti-pulling RJ-45 plug cannot be pulled out; the reverse card and the reverse card elastic sheet are completely inserted into the RJ-45 socket, so that the possibility of accidental touch is avoided, and the dead weight of the jumper wire cannot influence the reverse card and the reverse card elastic sheet, so that the jumper wire is prevented from falling off; when the anti-pulling RJ-45 plug is additionally provided with the lock hole base, the reverse clamping elastic sheet cannot be extruded by external force except a special key, namely, the reverse clamping cannot be released from a locking state. The key is kept by a high-authority network manager, corresponding network maintenance personnel are authorized only when necessary, unauthorized patch cord plugging management is prevented, and network physical safety is improved; the key applies pressure to the reverse card spring sheet through the unlocking hole to enable the reverse card to be downwards unlocked, and the anti-pulling RJ-45 plug is pulled out of the RJ-45 socket to complete unlocking.
