Description

Single side jumping type teminal mould block for outer wire of general wire assembling frame

The utility model relates to the communication support facility field, is in particular a kind of outside line that is used for single face wire-jumper type main frame and becomes the end module.

At present, China's urban telephone density increases rapidly, the institute of telephone office of high-capacity constantly occurs, demand to single face wire-jumper type main frame is growing, still can not reach the requirement of China's " main frame specification requirement and test method " industry standard and cost height fully from the single face wire-jumper type main frame of external import on serviceability, as U.S. COSMIC II A distributing frame system, its every row can adorn 50,000 pairs of outside lines, can adorn 8 rows at most, and total capacity reaches 400,000 pairs.In order to save the space, the front of this distributing frame is only adorned wire jumper and is become the end module, the Security Unit socket is contained in the back side of outer coil holder, it and wire jumper become between the end module with the wiring connection, the outside line terminating cable then is connected the socket back by 710 modules, outside line terminating cable XianCheng end is on 710 bridge modules during installation, and 710 modules with the socket back are crimped on together again.The D2000NP single face wire-jumper type main frame of Japan NEC Corporation, the Security Unit socket also is contained in the frame back side, the direct Cheng Duan of outside line terminating cable is in the front of Security Unit socket, the wire jumper in socket and frame front becomes between the end module also with the wiring connection, and it all is to be welded on the base plate that printed board does that the wire jumper in frame front becomes the Security Unit socket at the end module and the frame back side, and therefore the price of above two kinds of distributing frames is all very expensive.

The purpose of this utility model is exactly in order to overcome the above-mentioned deficiency of prior art, and provide a kind of outside line is become the end terminal, and the outside line that wire jumper becomes end terminal and Security Unit socket to be made in the single face wire-jumper type main frame on the same module becomes to hold module.

Technical solution of the present utility model is as follows:

A kind of single face wire-jumper type main frame outside line becomes the end module, it includes outside line and becomes the end terminal, wire jumper becomes the end terminal, the Security Unit socket, outside line becomes the end terminal, wire jumper becomes the end terminal, the Security Unit socket is made on same the module, it is last that outside line becomes the end terminal to become an end of end terminal with wire jumper, two arrange down, divide the front that is located at module, outside line becomes the end terminal to become the other end of end terminal all to stretch to the back side and the grounding reed of module with wire jumper, and the signal reed constitutes the Security Unit receptacle pin together, upper surface middle part in module is provided with the separated time shelves, on the installing rack that opens wide in the middle of the two ends of module are fixed on, the horizontal cabling of outside line and wire jumper is placed in the slit of two intermodules, outside line in the back, wire jumper is in front.

Advantage of the present utility model is, outside line is become the end terminal, and wire jumper becomes the end terminal, and the Security Unit socket is made on the module, having cancelled the wiring that becomes between end module and the Security Unit socket connects, save material, reduced production man-hour, greatly reduced cost, cancelled the contact point that becomes between end terminal and the Security Unit socket, improve reliability, increased holding wire, can satisfy the requirement of China's industry standard.

The utility model is further described as follows below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation

Fig. 2 is the A-A profile of Fig. 1

As Fig. 1, shown in Figure 2, during the utility model work, the two ends of module 4 are fixed on the middle installing rack that opens wide, as with a kind of and clamping reed 6 lead angle at 45,7 make the end terminal, with outside line is that cable is that outside line becomes on the end terminal 1 by 5 one-tenth ends of separated time shelves at last row's terminal, under to arrange terminal be that wire jumper becomes 2 of end terminals for wire jumper Cheng Duanyong, the horizontal cabling of cable and wire jumper, be placed in the slit of 4 of two modules, cable in the back, wire jumper is in front, become the other end of end terminal to stretch to the back side of module 4, constitute the Security Unit receptacle pin, Security Unit is inserted in the back side of module, becomes end terminal 1 to become end terminal 2 to be communicated with wire jumper outside line.In addition, the central authorities at the module back side, every loop line also has 2 holes, and grounding reed 8 and signal reed 9 are equipped with in the inside, and be corresponding with grounding pin and signal pins on the Security Unit.The capacity of module can be made 25 pairs or 10 pairs, decides on distributing frame overall plan, and wire jumper enters the little jumper ring at place, module slit, can be made in the both ends or one end of module, also can be made in addition on the installing rack, and the utility model also can be used for other occasion that is suitable for.

Claims (1)

1, a kind of single face wire-jumper type main frame outside line becomes the end module, it includes outside line and becomes end terminal 1, wire jumper becomes end terminal 2, Security Unit socket 3, it is characterized in that outside line is become end terminal 1, wire jumper becomes end terminal 2, Security Unit socket 3 is made on same the module 4, it is last that outside line becomes end terminal 1 to become an end of end terminal 2 with wire jumper, two arrange down, divide the front that is located at module 4, outside line becomes end terminal 1 to become the other end of end terminal 2 all to stretch to the back side and the grounding reed 8 of module 4 with wire jumper, and signal reed 9 constitutes the Security Unit receptacle pin together, upper surface middle part in module 4 is provided with separated time shelves 5, on the installing rack that opens wide in the middle of the two ends of module 4 are fixed on, the horizontal cabling of outside line and wire jumper is placed in the slit of 4 of two modules, outside line in the back, wire jumper is in front.
