The invention relates to a duplex connector, which contains two fasteners for receiving two single plug-in connectors to form one duplex plug connector.
This type duplex connector, according to his birth is known from U.S. patent 5579425. This duplex connector includes a plate element on the side walls of which are respectively made two different ways cylindrical pin, which is intended to sticking in the corresponding holes in the housing of the connector, namely a single plug. On the upper side of this plate element placed arcuate element, which in the assembled condition, is engaged with the locking clip single plug connector, so that when exposed to the arcuate element both retainer clip single plug connectors are raceplane at the same time. Single connectors on both sides of his body with openings so that every single plug-in connector can be placed on either side of the duplex connector. Due to this, it is possible, for example, a subsequent change channels through the change or replacement of a single plug. Thus by duplex connector provides the possibility of obtaining two single plug connectors of the same duplex plug connector. Another advantage is that in case of a defect of one single plug connector should be replaced only this defective plug connector. The disadvantage of this known duplex connector is missing as mechanical connections, and limited applicability.
Therefore, the basis of the invention is to create such a duplex connector for glass fiber connectors, which would provide the possibility of universal insert and implementation of an improved mechanical connection between the duplex connector and the plug connector.
The solution to this problem is the subject of the invention according to the characteristics of paragraph 1 of the claims. Other preferred forms of execution of the invention follow from the dependent claims. To solve this problem, the mounting hardware is designed in such a way that they cover at least partially a socket housing and a means of protecting the cable from bending to be hosted in the fixing device plug connector. Thanks to be be placed in the fixing device plug connector is firmly clamped by the fastening device, and the clamping forces are distributed around the plug housing or enclosure in accordance with the form of the fasteners. Another advantage of the duplex connector according to the invention is that it actually does not need any mechanical, proactive supports at the plug connector. Thanks to this duplex connector provides the possibility of universal application plug-in connectors from various manufacturers.
In one preferred form of the fastening device made in the form of C-shaped nests, so that they spring force to securely clamp the appropriate means of protecting the cable from bending. While the open shelves of a C-shaped slot provided mainly by the chamfer to the plug-in connector can be easily entered into the socket.
In another preferred form of execution in the longitudinal direction of the duplex connector to the C-shaped slot adjacent rectangular slot. This socket is designed for reliable clamping part of plug housing. Thus a duplex connector securely grip the plug-in connector at the same time, protection of the cable against bending and at the plug housing, which provides especially strong mechanical connection.
A rectangular slot is made preferably and essentially L-shaped, and open shelves preferably provided with a chamfer. Further L-shaped slot provided with a cross bridge, protruding above the upper side of the plug housing.
According to another preferred form of execution on the upper side is arcuate element so that it is in the docked position single plug connector covers their clips, so that when exposed to the aforementioned arcuate element simultaneously operate both single clip plug connectors.
Hereinafter the invention is explained in more detail based on a preferred exemplary embodiment with reference to the drawings, showing:
figure 1 is a perspective rear view of the duplex connector;
figure 2 is a perspective front view of the duplex connector;
figure 3 - side view of the duplex connector;
4 is a exploded view of a duplex connector with two single connectors;
figure 5 - image duplex connectors from one duplex connector and two single plug connector in assembled condition;
6 is a side view of a duplex connectors.
Duplex connector 1 contains the top side 2 and bottom side 3, between which is located in the middle of the wall element 4 in the form of an inter-connector. On each side of this wall element 4 has one S-shaped slot 5 and one L-shaped slot 6. C-shaped slot 5 extends across the entire width of the lower part 3 duplex connector 1. The ends 7 of the upper shelves provided with a chamfer 8, and the ends 9 of the lower shelves provided with a chamfer 10. The end face 9 of the bottom shelf extends along the entire length L duplex connector 1, while the end face 7 only comes to L-shaped slot 6. Parallel to the upper side 2 duplex connector 1 in the area of the L-shaped slot 6 is a transverse crosspiece 11, which is slightly narrower In width duplex connector 1. This transverse crosspiece 11 is also provided with a chamfer 12. The length of a C-shaped slot 5 is approximately two times greater than the length of the L-shaped slot 6. On the upper side 2 is arcuate or curved element 13, which passes at an angle from the front side to the end side of the duplex connector and goes to the part that is parallel to the top side 2.
Figure 4 shows a duplex connector 1 according to figure 1-3 with two single connectors 14. These both single plug connector 14 is identical. Each of these single plug connector contains its own fibre-optic cable 15, a latch 16 cable sheath, the tool 17 protection of the cable against bending, and a socket housing 18. 17 protection of the cable against bending is mounted from one conical and one cylindrical part and the cylindrical part facing toward the plug body 18. This plug housing 18 is fast snap clip 19, which is designed for locking and released the plug connector 14 with the corresponding socket. Himself a socket housing 18 is made essentially rectangular shape. Snap the clip 19 is assembled from one retainer clip 20 and one deblokiruyuschee clamp 21, as is more fully explained in figure 6.
Figure 5 shows a complete, full-duplex plug connector 22. The cylindrical part of the tool 17 protection against bending securely in the C-shaped slot 5, and the portion of the plug housing 18, in turn, is securely fastened to L-shaped slot 6. Due to the presence of lateral coverage of the slots 5, 6 ends 7, 9 with their chamfers 8, 10 is provided mechanically very stable terminal connection. Arcuate element 13 when thus acts on both clamps 19 both single plug connectors 14 that they both can be disconnected simultaneously.
As is evident from Fig.6, deblokiruyuschee clamps 21 protrude above the locking clips 20 and the arcuate element 13 acts over debateroom clamps 21. If a duplex plug-in connector 22 is inserted into the slot, the retainer clips 20 stopped in the nest. By clicking on the beveled portion of the arcuate element 13 deblokiruyuschee clamps 21 are pressed in a downward direction. These deblokiruyuschee clamps 21, in turn, push down on the locking clamps 20, so that all the clips raspoliruyte and duplex plug connector 22 can be closed.
