This invention relates to a connection block used in supply connection including an installing board with N pairs of connection posts of 0V and working voltage characterizing that the front of the board includes a front baseplate and at least one stage of upward or downward step along the side of the baseplate, when the number of the front steps is N, then each of the step is distributed with a connection post of working voltage and the front baseplate is distributed with N connection posts of 0V in displacement, which can not only keep the original routing mode but also support the mode that a supply line enters from the side by setting front steps on a front baseplate especially convenient for the access of unpliant thick cables.

Description

A kind of tagblock

Technical field

The present invention relates to a kind of tagblock, especially refer to be used for the tagblock on ISAM (intelligent subscriber access device) frame.

Background technology

Traditional single service DSLAM (Digital Subscriber Line access device), be ATMDSLAM (based on the Digital Subscriber Line access device of ATM agreement) or IP DSLAM (based on the Digital Subscriber Line Access Multiplexer of IP agreement), nowadays forward MSAN evolution, such as 7302ISAM FD (7302 intelligent subscriber line access device), its emphasis is to guarantee to provide multi-service to all users, no matter it is business user or resident.

7302ISAM FD access device has changed in the past that the user of ADSL (ADSL (Asymmetric Digital Subscriber Line)) access device inserts the restriction that density is subjected to frame and divides frame density, thereby makes that the access capability of system is increased significantly.7302ISAM FD not only can support ADSL, ADSL2, and ADSL2+ and VDSL business, and can support simultaneously high bandwidth access service such as following PON.

7302ISAM FD access device is when enriching access service, from the actual installation demand of telecommunication user, with smaller volume and flexibly installation method increased on-the-spot packing density, for example, under identical occupation of land condition, access customer number density can improve more than 30%.Mounting means requires to divide frame itself to have stronger flexibility with being connected of external equipment flexibly, and wherein: the power supply cabling mode must be flexibly.

As shown in Figure 1, the existing power supply wiring piece that is installed in the frame bottom left of ISAM access device, comprise a mounting panel 4 ', this mounting panel 4 ' on be provided with some positive and negative electrode binding posts 1 to upper and lower layout ', 2 ', and the and arranged on left and right sides of every pairs of posts in this mounting panel 4 ' front be respectively equipped with division board 3 '.Therefore, power line is generally from the above and below cabling of two division boards, or left side or right side cabling.

But, if power line is from mounting panel left side or during the cabling of right side, after often needing power line bending detoured again from the above and below cabling of division board, for thick slightly power line, not only be difficult for bending, and the bending angle also be difficult to control, thereby cause the ordering of power supply cabling improper, influence the fail safe of power supply cabling;

The second, the division board that every pairs of posts and arranged on left and right sides is provided with, its spacing have limited the space of wiring operation, make operating condition be subjected to all multifactor (for example: restriction operation tool).

Summary of the invention

The object of the present invention is to provide a kind of can independently being used for to support the tagblock of cable on the frame, and guarantee the convenience of flexibility, fail safe and the wiring operation of cabling from a plurality of direction cablings.

A kind of tagblock provided by the present invention, be used for power supply wiring, the N that comprise a mounting panel, is provided with on this mounting panel is characterized in that the binding post of 0V and operating voltage: the front step up or down of one-level at least that the soleplate lateral margin was provided with before be somebody's turn to do on soleplate and edge before the front portion of described mounting panel comprised.

In above-mentioned tagblock, when anterior step progression is N, then on each grade front step, distribute one be the binding post of operating voltage, and the N that is dislocatedly distributed on the soleplate before described is individual is the binding post of 0V; When anterior step progression was 1, the N that then is dislocatedly distributed on this front step be the binding post of operating voltage, and the N that also is dislocatedly distributed on the soleplate before described is individual is the binding post of 0V.

Further, before described, be respectively equipped with limited post on each angle of soleplate and front step.

In above-mentioned tagblock, the height of described each grade front step is more than or equal to the external diameter of power line.

Yet the rear portion of described mounting panel can be flat board, also can be formed by the back soleplate with along the back step of one-level at least of this back soleplate lateral margin setting.

Preferably, back step progression is N, and N level back step can be a step up or down.

The present invention also provides a kind of tagblock, the N that comprise a mounting panel, is provided with on this a mounting panel binding post is characterized in that: the front step up or down of one-level at least that the soleplate lateral margin was provided with before be somebody's turn to do on soleplate and edge before the front portion of described mounting panel comprised.

Further, the rear portion of mounting panel comprises back soleplate and the back step of one-level at least that is provided with along this back soleplate lateral margin.

Owing to adopted above-mentioned technical solution, the present invention has overcome the limitation of existing power supply cabling mode, not only can keep original power supply cabling mode, and front step by on preceding soleplate, being provided with, support the mode of connection that power line (comprising holding wire) enters from the side, especially be convenient to the access of unpliant thick cable, thereby guarantee flexibility, the fail safe of cable cabling, also make the wiring operation more convenient simultaneously.The present invention can be applied independently in the frame of ISAM access device and the ETSI frame so that the cable cabling is more flexible.

Description of drawings

Fig. 1 is the structural representation of existing power supply tagblock;

Fig. 2 is the stereogram of the most preferred embodiment of tagblock of the present invention;

Fig. 2 (a)～(c) is respectively front view, upward view and the left view of Fig. 2.

Embodiment

One, one of the present invention's execution mode:

As shown in Figure 2, the present invention is used for the most preferred embodiment of the tagblock of power supply wiring, two couples of 0V, operating voltage (or positive and negative electrode) binding post 21/22,31/32 that it comprises a mounting panel 1, is provided with on this mounting panel 1.

Referring to Fig. 2 (a), the two-stage front step 112,113 that soleplate 111 lateral margins were provided with before be somebody's turn to do on soleplate 111 and edge before the front portion 11 of mounting panel 1 comprised.

Referring to Fig. 2 (b), when tagblock of the present invention was installed in the left side of frame, general two-stage front step was a step upwards, so that power line enters from the left side.

When tagblock of the present invention was installed in the right side of frame, the two-stage front step was generally to getting out of a predicament or an embarrassing situation, so that power line enters from the right side.

Again referring to Fig. 2 (a), Fig. 2 (c), two 0V that on preceding soleplate 111, are dislocatedly distributed (or anodal) binding

post
