Description

Main frame security personnel's Wiring module

The utility model relates to a kind of Wiring module of telecommunication apparatus, is specifically related to be used for a kind of security personnel's Wiring module of main frame.

Main frame is the interface equipment between telephone subscriber and the switchboard circuit; its functional block is made up of security personnel's Wiring module and test Wiring module; wherein ensure public security and protector is housed on the Wiring module; have overvoltage, overcurrent, forceful electric power defencive function; and when taking place, fault sends audible and visual alarm; security personnel's Wiring module is the main frame main function components, and the size of its performance and overall dimensions directly affects the quality and the capacity of main frame.And existing security personnel's Wiring module is because structural design is unreasonable, shortcomings such as the ubiquity volume is big, capacity is little, Operation and Maintenance inconvenience, and this increases day by day to the demand of high-density module under the existence conditions of machine room space growing tension.

The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art, proposes a kind of the assurance under the prerequisite of safeguard function, and is rational in infrastructure, volume is little, security personnel's Wiring module of convenient operating maintenance.Realize the technical scheme of above-mentioned purpose: a kind of main frame security personnel's Wiring module, be fixed with card line terminals and signal lines and ground wire terminal on the housing, there are outside line entrance hole and wire jumper entrance hole in the left and right sides in the card line terminals, the two sides up and down of card line terminals are fixed with the outside line frid and the wire jumper frid of the different deep-slotted chip breaker height of tool, the deep-slotted chip breaker inlet of outside line frid is the outside line entrance hole, the deep-slotted chip breaker inlet of wire jumper frid is the wire jumper entrance hole, and the connected mode between outside line frid, wire jumper frid and the card line terminals two sides is that ultrasonic bonding is fixed.

It is the dual-mouth structure of 4.9mm that the terminal plate of card line terminals adopts width.

There is jack at the rear portion of housing, and each blocks the line terminals signal lines and connects by the copper bar that inserts in the jack.

Be connected to alarm indicator on the holding wire.

With the both sides of security personnel's Wiring module the sign bar is housed at main frame, the sign bar is connected by dovetail groove between the Wiring module with ensuring public security with main frame.

Adopt technique scheme, its tangible technique effect is: the positive clamping terminal of 1, the outside line of left and right sides structure, wire jumper inlet wire and double-deck up and down dual-mouth structure and the guiding of the deep-slotted chip breaker on the corresponding frid, make modular structure orderly, compact, reasonable, both be convenient to Operation and Maintenance, guaranteed the profile width dimensions that module is less again; 2, because outside line and wire jumper and frid thereof are absolute construction, and be connected with the supersonic welding fixed form with module bodies, can form left and right sides through wires hole by different designs and vary in size, thereby under the demand of as far as possible reducing module thickness, satisfy actual instructions for use each frid height; 3, the holding wire articulation set is in plastic module inside, insert by a copper bar at last, the holding wire of each module is linked together, and connect alarm indicator, this mode had both made things convenient for each module to install one by one, had guaranteed the compact conformation and the globality of multistage module stack again; 4, adopt plastic cement to make the sign bar of oat tail groove structure, improved the intensity and the globality of module, the sign bar is printed on number-mark, and the wire size when having made things convenient for working service is searched.

Below in conjunction with accompanying drawing, its structure is described in detail in detail by embodiment:

Fig. 1 is 10 loop module surface structure schematic diagrames of the present utility model.

Fig. 2 is another angular views of Fig. 1 surface structure.

Fig. 3 is the structural representation of threading frid.

Fig. 4 is holding wire connection hole, a module rear portion partly cut-away enlarged drawing.

Card line terminals sheet bayonet arrangement signal in Fig. 5 module.

Fig. 6 is that the sign bar is connected with module and 100 loop module surface structure schematic diagrames.

Embodiment: a kind of main frame, mainly is made up of the front card line terminals on housing 1, frid (8,9) and the housing 1 in conjunction with Fig. 1～Fig. 6 with security personnel's Wiring module.Positive card line terminals is the outside line by up-down structure, wire jumper is formed with card line terminals row 4, socket 3 is arranged therebetween, it is the structure of the tool dual-mouth groove 10 of 4.9mm that each terminal plate of card line terminals row 4 adopts width shown in Figure 5, positive card line terminals row's 4 two sides up and down are fixed with the outside line frid 8 and the wire jumper frid 9 of differing heights with ultrasonic bonding, frid (8, deep-slotted chip breaker is arranged 9), the deep-slotted chip breaker inlet of outside line frid 8 is outside line entrance hole 6, the deep-slotted chip breaker inlet of wire jumper frid 9 is wire jumper entrance hole 7, outside line entrance hole 6 and wire jumper entrance hole 7 are left and right sides structure, frid (8, the card line terminals row's 4 of the corresponding up-down structure of outlet 9) terminal plate, not collinear footpath requirement according to outside line and wire jumper, the deep-slotted chip breaker groove of frid 8 is shallow, the deep-slotted chip breaker groove depth of frid 9.The middle part upper and lower is symmetrically fixed with Metal Contact formula terminal 11 in the socket 3 of card line terminals, respectively as holding wire terminal and earth connection terminal, there is jack 2 at the rear portion of housing 1, each blocks, and signal lines terminal 11 connects by the copper bar 12 that inserts in the jack 2 in the line terminals, and be serially connected with alarm indicator 5, the earth connection terminal adopts elastic copper sheet to make, and is external through the otch 13 at housing 1 rear portion.
