Abstract
The utility model discloses a branching device for a device end of a telecommunication office, wherein, a plurality of groups branching circuits which are used for the transportation of a low pass filter are arranged on a circuit board, each setting path of the circuits is respectively connected in series with electronic elements, such as a surge absorber, a communicating transformer, a high voltage condenser, a surface adhesion type electric inductor, a fuse, etc. The electronic elements which are connected in series one by one form control groups on the predetermined circuit path of the circuit board, a plurality of groups of gate numbers are simultaneously treated by a plurality of groups of the control groups, and the electronic elements are orderly arranged on each circuit path through the control groups so as to be favorable for automation of welding fabrication, and increase of fabricating efficiency. In addition, each electronic element of the control groups is exposed and arranged on the circuits of the circuit board, and the utility model can make the heat dissipation and the checking operation convenient.
Description
Technical field
The utility model relates to a kind of telephonic communication technology, refers to a kind of telecommunication bureau equipment end difference device especially.
Background technology
At present, telecommunication bureau is traditional such as the voice call business for the user provides it also can possess when using the networking, it mostly is to be divided into two with the transmission signal of difference device with voice and networking operation, the difference device structure that tradition is adopted is (it is example that shown by reference numeral is only lifted one group) as shown in Figure 2, it mainly is to cooperate component sets such as some fuse B and communications transformer C to be located on the circuit board D of etched circuit by some groups of low pass filter A, and by the circuit on it separately, see through the connector E on the circuit board with speech sound signal and networking signal, F transmits networking signal and speech sound signal; Yet, this structure at first blush, as if electronic component is few, it is respectively organized low pass filter A circuit and all is loaded in the shell in fact, installed array electronic component (array inductor and capacitor) in its enclosure, after mutual connection is established mutually by the pin of each electronic component and shell periphery, be arranged on the circuit board D with this shell unification again, use the latent electronic components such as capacitor and inductor of putting.
Therefore, there is following shortcoming in this kind traditional structure, mainly is summarized as follows:
1, comprised many groups electronic component in this shell, annexation therebetween need rely on artificial welding manner and handle, pouring into is packaged in electronic component in the shell as colloid materials such as epoxy resin fully again, be connected to the pin of shell periphery on the circuit board together by artificial welding manner again, because electronic component piles up in the enclosure, can't handle automatically with computerization totally at all, its required manpower that expends is more, it is less relatively to make output, and cost is very expensive.
2, this structure is because total latent placing in the shell, if in the time of need carrying out element testing, promptly must destroy shell and make its inner electronic component expose totally and can detect, yet, some groups of above circuit often be provided with on the circuit board, if detect according to this kind mode, its spent time is very considerable, has no efficient at all and can say, in case that electronic component detects is intact no problem, often can't weld use more again, very cost of idleness.
3, be provided with the array electronic component in this shell,,, will cause the bad system that makes of low-pass filter circuit heat radiation extremely unstable, therefore, often have when the generation of situations such as machine if when airtight fully situation owing to electronic component can produce temperature when switching on.
The utility model content
The purpose of this utility model is to provide a kind of and overhauls conveniently, heat radiation is good, make the high telecommunication bureau's equipment end difference device of efficient.
For achieving the above object, solution of the present utility model is: a kind of telecommunication bureau equipment end difference device structure, wherein, planning is provided with the difference circuit for the low pass filter transmission on the circuit board, it is characterized in that: each bar circuit be provided with on the path respectively that serial connection is provided with surge absorber, communications transformer, high-voltage capacitance, surface stuck inductor and fuse, the electronic component of aforementioned series connection one by one forms control group in the default circuit paths of circuit board, and each electronic component of controlling group is listed as in regular turn and places on each bar circuit paths.
After adopting said structure, owing to can lose system circuit trend on the circuit board in advance, so no matter respectively organize electronic component and be with directly to, horizontal or oblique being arranged on the circuit board, it is provided with the path and all is on the plane that systematicness is arranged at circuit board, so can be by the pin of each electronic component of computer automation rapid welding, need not to rely on traditional manpower again and weld one by one, its processing procedure is speed and convenience, can effectively improve the slow and time-consuming shortcoming of traditional manpower welding; In addition, each electronic component all exposes on the circuit that is arranged at circuit board in the control group, can make on heat radiation and the upkeep operation more conveniently, and helps to keep the stability of telecommunication system, thoroughly improves conventional process slowly and shortcoming such as inefficiency.

Embodiment
As shown in Figure 1, the utility model mainly is provided with signal transmission connector 11 in circuit board 1,12,13, and relatively on the signal transmission channel some of etchings be directly to, the circuit of horizontal or oblique Boulez, and be respectively equipped with some surge absorbers 2 on the path in being provided with of first group of circuit, communications transformer 3, transformation electric capacity 4, electronic components (it is example that shown by reference numeral is only lifted one group) such as surface stuck inductor 5 and fuse 6, make and respectively organize electronic component and connect one by one to be arranged at and have a control group on the default circuit paths of circuit board 1 of one's own, control one group of door number respectively by each group control group, thus on same circuit board 1 the control group of setting at least 8 groups or 24 groups; Owing to can lose system circuit trend on the circuit board 1 in advance, so no matter respectively organize electronic component and be with directly to, horizontal or oblique being arranged on the circuit board 1, because being provided with the path, it all is on the plane that systematicness is arranged at circuit board 1, so can be by the pin of each electronic component of computer automation rapid welding, need not to rely on traditional manpower welds one by one again, its processing procedure is speed and convenience, can effectively improve the slow and time-consuming shortcoming of traditional manpower welding.
In addition, each electronic component all exposes on the circuit that is arranged at circuit board 1 in the control group, can make on heat radiation and the upkeep operation more conveniently, and helps to keep the stability of telecommunication system, thoroughly improves conventional process slowly and shortcoming such as inefficiency.
