The present invention relates to a high-density protection base for all-electronic exchanger, and more particularly, to a high-density protection base configured to be able to conveniently perform various operations, to accommodate a high-density subscription line.

The Protector Connection Book is a mechanism that accommodates the protection circuit that protects the Digital Exchanger from overvoltage and overcurrent flowing into the communication line due to power line touch, power induction and direct and indirect lightning strikes. Connect subscriber line and exchange by connecting with terminal of exchange.

The protection base includes a protector connection panel that accommodates multiple protectors (one line of protection circuit), a group test panel that enables group testing, a jumper wire terminal panel that facilitates jumper wire operation and jumper wire arrangement, and jumpers It consists of an outer wire terminal panel etc. which accommodate a guide outer wire (subscriber telephone line and switchboard line).

However, since the protection base used in the prior art has all of the protector connection panel, the group test panel, the jumper wire terminal panel, and the external terminal panel, the number of protectors fastened to the protector connection panel is limited, and the overall width is also limited. Since it is made relatively wide, it requires a large mounting space in the wiring board in which a plurality of protection bases are installed. In addition, the jumper line guide (Jumper Line Guide) formed on the side of the jumper terminal panel is formed in a hole shape, causing inconvenience to the removal and connection work of the jumper wire related to telephone installation, removal.

That is, the jumper wire is connected to or separated from the jumper terminal (exchange circuit) through the hole one by one. Therefore, the present invention is to solve various problems of the existing protection base, and the frequently used line test terminal and jumper wire terminal panel are configured on the front side, and the protector connection panel for fastening the protector is configured on the side. The purpose of the present invention is to provide a high-density protection base that can increase the efficiency of the circuit board and minimize the mounting space in the wiring board.

The high-density protection base according to the present invention constitutes a protector connecting panel 20 in which protector connecting terminals 22 are fastened to one side of the plurality of protectors 21, and a test terminal 31 is disposed on the front side. The jumper terminal panel 40 in which the collective test panel 30 and the jumper terminal 41 are arranged is formed over the entire height of the member, and another side portion includes a jumper guide part 50 for accommodating and dispersing jumper wires. In the rear part, the outer terminal panel 60 in which the outer terminal 61 is arranged is characterized in that each is configured.

Hereinafter, with reference to the accompanying drawings of the present invention will be described in detail. 1 is a perspective view of a high-density protection base according to the present invention, the biggest feature of the present invention is a protection base (20) in which a plurality of protector connection terminals 22 that can connect the protector 21 is arranged It is configured in the side part of 10). Accordingly, a jumper terminal panel 40 in which a group test panel 30 in which line test terminals 31 are arranged on one side and a plurality of jumper wire terminals 41 on another side of the protection base 10 is arranged. It is constructed over the entire height of this protection base 10.

Partial features of the protection base 10 will be described in detail through an angle plane, and FIG. 3 is a left side view of the state in which the protector 21 shown in FIG. 1 is removed. A plurality of protector connection terminals 21 each composed of two pins and a single jack type grounding terminal are configured (100 x 5) to connect 100 protectors (the size of FIG. 1). Only some of the protectors are shown).

This means that the protector connection panel, together with the group test panel and the jumper wire terminal panel, can connect more protectors than the protective structure (same size) of the existing structure constructed on the front of the protective base.

FIG. 2 is a front view of the present invention, in which a group test panel 30 is provided at one side and a jumper terminal panel 40 is arranged at one side over a height before the member.

Group test panel 30 is composed of a test terminal 31 of 100 lines (5 × 20), it is possible to test up to 100 lines, as well as test by one line.

The jumper terminal panel 40 includes a test terminal 31 and an equal number of jumper terminals 41 formed in the group test panel 30, and a jumper guide part 50 for arranging a plurality of jumper wires at the outer end thereof. do. In order to explain the configuration of the jumper guide portion 50 in more detail with reference to FIGS. 2 and 4, FIG. 4 is a right side view of FIG. 1, and the jumper guide portion 50 is formed at the rear end portion. Jumper terminal side jumper guides (55A, 52B, 52C, and 52D) for arranging jumper wires per line, and jumper terminal side jumper guides (55-1, 55-2 for arranging jumper wires in units of 5 lines) , .... It is doubled as 55-20), so it is easy to arrange the jumper wire.

The jumper guides 52A, 52B, 52C, and 52D on the wiring board side have 50 lines of jumper wires inflow and dispersion through corresponding jumper wire inlets 51A, 51B, 51C, and 51D, respectively, and jumper guides 52A of each wiring half shaft. , 52B, 52C, and 52D) and the respective jumper wire inlets 51A, 51B, 51C, and 51D were cut in a predetermined depth to prevent the jumper wire from being received and protruding out of the member.

Each of the 20 jumper terminal side jumper guides 55-1, 55-2, .... 55-20 cuts the side surface portion of the protective base 10 to a predetermined length and depth so that each recess 53-1, 53- 2, ... 53-20, and by cutting the member corresponding to each of the grooves 53-1, 53-2, .... 53-20 on the front part, as shown in FIG. As described above, a jumper wire outlet port 54-1, 54-2,... 54-20 is formed on the front side of the jumper guide part 50 of the protection base 10.

If the front member forming the outlets 54-1, 54-2, .... 54-20 is extended up and down, the outlet may be narrower than the groove to prevent sagging through the outlet of the jumper wire. Each jumper wire outlet 54-1, 54-2, .... 54-20 corresponds to one row (five) of jumper terminals 41 of the jumper terminal panel 40, and each of the five grooves ( 53-1, 53-2, .... 53-20 correspond to the singular wiring end side jumper guides 52A, 52B, 52C, and 52D.

Each 50-line jumper wire in the form of a cable is accommodated in each of the wiring board side jumper guides 52A, 52B, 52C, and 52D through the jumper wire inlets 51A, 51B, 51C, and 51D. Grooves (53-1, 53-2, .... 53-20) and outlets (54-1, 54) of jumper guides 55-1, 55-2, .... 55-20 on each jumper terminal side It is connected to each jumper terminal 41 via -2, .... 54-20). The jumper guide part 50 arranges a large amount of jumper wires five times and connects them to the jumper terminals 41, thereby facilitating the arrangement of the jumper wires, and also the jumper wire inlets 51A, 51B, 51C, and 51D. The outlets 54-1, 54-2, .... 54-20 are made of cutouts, not holes, so that they can be easily removed after disconnection from each jumper terminal. Bolt holes).

FIG. 5 is a rear view of FIG. 1, and the outer terminal panel 60 having a plurality of outer terminals 61 (subscriber side) is formed, and another one side includes jumper wire inlets 51A, 51B, 51C, and 51D. Shown.

The present invention as described above is that the protector connection panel is configured on the side of the protection base, not the front side, the amount of protector connected to the protection base is increased to improve the function of the protection base, and the width of the front is reduced, the wiring board It is possible to reduce the protection-based mounting space in the interior.

In addition, by constructing a jumper wire guide, not only can a large number of jumper wires be arranged, but also connection and disconnection operations at the jumper terminals can be easily performed.
