The invention relates to a distribution block for telecommunications and data technology, in particular for the main distribution frame of telephone and data lines, having contact springs 1. The springs are arranged in the interior of the modular distribution block and are formed from connection contacts 7, 8, using insulation-piercing terminal technology in the front and rear side of the block and from a telecommunications contact 22 in the central region. A pick-off contact 19 is formed in the front region of the contact spring 1. A distribution block of the generic type is provided which contains an uncomplicated contact element and on which the wire routing is improved and in which reliable fitting of the cable wires is ensured. The contact spring 1 is formed from a base part 3 and a contact spring part 2 fitted to it, fixing points 4 for the longitudinal direction and an opening 6 for the fitted contact spring part to pass through being provided in the central region of the base part 3. A hole 5 is arranged in the front region of the base part in order to fix the position of the contact spring part 2 to be fitted.

Description

The distribution block that is used for telecommunications and data technique

The present invention relates to be used for the distribution block of telecommunications and data technique, particularly according to the main-frame that is used for phone and data circuit of the description of claim 1 part.

Such electrical power wiring assembly is used as the interface of each telephone subscriber point and switch especially for the main-frame in the telephone system.

DE 19537529.7 discloses a kind of distribution block that is used for telecommunications and data technique, especially for the distribution block in the main-frame of phone and data circuit, this distribution block has the isolation-feedthrough terminal contact component that connects user and switchboard cable, with this distribution block be modular construction and within it side contain the spring that contacts of whole formation.The integral body contact spring that is arranged in the inboard of this distribution block is to utilize in the isolation-feedthrough terminal technology of the front and back of this part side by connecting that contact constitutes and forming a telecommunications contact in the center.This telecommunications contact comprises can be according to two contact faces of two point formation.Proparea at the contact spring constitutes a sensing contact (pick-off contact).The manufacturing of this whole contact spring is complicated.

The present invention is the purpose that comprises the distribution block of uncomplicated contact according to improvement, and in view of the above, has improved the trend of circuit and has wherein guaranteed the installation reliability of cable.

This purpose is that the feature by claim 1 realizes.According to two parts contacts spring that is divided into essential part and contacts the spring partial design of the present invention, guaranteed the conserve space manufacturing of each contact of uncomplicated, distribution block, its manufacture process can realize automation.The designing two portions of contact spring makes different materials will be bonded to one, thereby guarantees that the contact characteristic is being optimized aspect the spring travel that will provide, contact strength and the defencive function.The isolation-feedthrough terminal contact areas of mould molding spare that is integrally formed in a side of housing parts guarantees that erecting tools can only be applied to isolation-feedthrough terminal contact in a direction.This assurance is cut off connected line all the time in correct side.

The wire channel of walking that is arranged on the side of this module makes to design easily with cabling and inserts line to each contact.

The clearly statement utilization of the other advantage of the present invention can obtain from each dependent claims.

The exemplary embodiment that reference table is shown in the distribution block in the accompanying drawing in the specification text below carries out more detailed explanation to the present invention.

Figure 10 represents to be used to isolate-and feedthrough terminal connects the amplification explanation of the groove range section of each contact.

For main-frame of structure in telecommunications and data network, comprise each distribution block according to the module 17 of Fig. 7 to 10 and vertically be arranged in overlappingly one by one and install on the frame, the state of this installation is not expressed out.Each distribution block forms a functional module, for example by the exchange connecting point position or by isolating connecting point position.This each distribution block comprises that some identical modules 17 and difference are their mutual alignment and/or arrange and be to have or do not have overvoltage protection plug or a similar device at the spring 1 of contacting according to Fig. 1 to 6.

Each distribution block comprises identical module 17 on two physical structures with cell 15 and groove 16, formation distribution block of pressing of this each module, and a contact spring 1 is mounted in each cell (Fig. 9).

Preceding and the back isolation-

feedthrough terminal

7,8 of contact spring 1 (Fig. 1 to 6) can enter groove 16.

In the contact zone 18 of isolation-feedthrough

terminal contact chip

7,8, a side and assurance that a chamfering (molding) 9 is integrally formed in the housing parts of module 17 only can be applied to isolation-feedthrough

terminal contact element

7,8 at assembly tool of a direction (Figure 10).This assurance always is cut off connected line in a correct side.

Corresponding to the explanation at Fig. 1 to 6, contact spring 1 is designed to two and constitute by essential part 3 with by contact spring part 2.

Part

2,3 can be utilized different made, so that realize the optimum value of spring travel and contact force.

Constitute the substrate of contact springs 1 according to Fig. 3,4 essential part 3.This essential part 3 has isolation-feedthrough

terminal contact chip

7,8 at each end.The fixing point 4 of longitudinal direction is arranged on middle section.Hole 5 is used to fixing contact spring part 2 to be installed, is used to contact spring 2 and can pass through what install with perforate 6.

Sensing contact 19 is used to make that contact has test plug.

Have 4 zones according to Fig. 5,6 contact spring part 2.First area 1 with boss 21 of a guidance contacts (guidestud) 20 and a welding is used to fixedly contact spring part 2 on essential part 1, for example by welding.

Second portion 2 is buckled zones, so that guarantee the spring travel in zone 3.

The zone 3 that contact point with

contact surface

23,22 is used for overvoltage protection and telecommunications contact utilizes a rib (bead) 24 to strengthen, so that guarantee that at two contact upper spring strokes approximately be identical.
