Description

Duplex fiber optic connector plug

This creation belongs to the field of fiber optic connectors, and more particularly to a plug structure for a duplex fiber optic connector that can be operated in a push-up manner.

According to the traditional network communication technology, copper wire (copper) wire is used as a network jumper to connect different cabinets in the network room, and can be used as a medium for data transmission through the transmission of electrical signals. However, with the development of network technology and the increasing amount of information, the way of transmission of electrical signals has gradually become insufficient, so it is used to transmit data with faster transmission speed. This method is often used in the connection of the mainframe room, for example, by the telecommunications bureau's network to connect to the community building or the office building's computer room.

As more and more information is used on the Internet, data is flowing into the network room and transmitted between the cabinets. It is gradually discovered that the amount of data transmitted by the existing copper network jumpers is gradually increasing. Can not keep up with demand, leading to the use of fiber optic jumpers for data transmission in the computer room. Compared with the traditional copper metal network jumper, the advantage of using the fiber jumper is that the fiber cable can be accommodated in a fixed diameter more than the traditional copper metal mesh route, and the size of most fiber connectors is also larger than that of the conventional network. The size of the road connector is small, and it can accommodate more fiber connectors than conventional network connectors under the same high density arrangement requirements. For this reason, the fiber optic connector has been improved from the previously large ST TYPE and FC TYPE to the current LC connector, which has greatly reduced the space occupied by it, resulting in the number of connectors that can be accommodated in the equipment room. Greatly increased.

Because of this, when the construction or maintenance of the optical fiber connectors is carried out, the maintenance personnel or the construction personnel often insert and remove the optical fiber connectors because the fingers cannot be inserted therein, and the optical fiber connectors must be pulled together with the adjacent optical fiber connectors. However, when it comes to plugging and unplugging at work, it must face the situation that it cannot touch other fiber connectors.

In order to solve the above problems, there are currently two treatment methods on the market, one is to clamp the connector by means of a clamping tool, and the other is to design a fiber optic connector with a special structure for pulling during operation. Pull out. For example, U.S. Patent No. 7,588,373, "Optical connector plug", discloses a fiber optic connector plug having a front end that is connected to the rear end of the plug body and extends rearward and upwardly, and has a fiber optic adapter in the middle of the shrapnel. a card point that is engaged with each other, and a rear end of the elastic piece has a flange structure, a rear end of the plug is connected with a sliding member, and a front end of the sliding member has a cam structure that is in contact with the flange structure, and when the sliding member can be displaced toward the rear end, The cam structure, that is, the back-end flange structure of the top-loading elastic piece, forces the elastic piece to be close to the plug body, so that the middle portion of the spring piece is separated from the fiber adapter, and the fiber connector can be pulled out of the fiber adapter. Or, for example, US Pat. No. 8,152,384, "Push-pull fiber optic connectors and methods for making the same", discloses a fiber optic connector plug structure having a front end connecting a plug body and extending upward and rearwardly on the plug, in the shrapnel The middle section has a card point that is engaged with the fiber optic adapter, and the fiber optic connector further includes a cover body slidable on the plug body, and the cover body has a decoupling member that contacts the front end of the spring piece, and the cover body can be The main body of the plug slides, and when the cover body and the unhooking member slide back at the same time, the unhooking member forces the rear end of the elastic piece to move downward, so that the card point of the middle portion of the elastic piece and the optical fiber adapter are separated from each other to disengage the optical fiber connector from the optical fiber adapter. Or as: US Patent US 8,221,007 "Plug The optical fiber connector plug disclosed in the connector having the unlocking mechanism has a front end connecting the plug main body and extending upward and rearward. The middle portion of the elastic piece has a card point which can be engaged with the optical fiber adapter, and the rear end of the elastic piece has a slope. The optical fiber connector plug further comprises a moving member movable relative to the main body of the plug, the front end forming an unlocking member contacting the inclined surface on both sides of the tail end of the elastic piece, and the unlocking member forcing the elastic piece after being relatively displaced by the moving moving member and the plug main body. Move down, causing the snap-on point on the shrapnel to detach from the fiber optic adapter. Or a fiber optic connector plug disclosed in the "Latching connector with remote release" of US Pat. No. 8,465,317, which has a front end connecting the plug body and extending upward and rearward, and has a fiber optic adapter in the middle of the shrapnel. The card point has an unlocking structure at the rear end of the elastic piece, and the unlocking structure is connected with a pulling belt. After pulling the pulling belt, the pulling belt structure is driven to force the elastic piece downward, so that the click point on the elastic piece is separated from the optical fiber adapter.
