INVENTION TITLE: Protective plug The following statement is a full description of this invention, including the best method of performing it known to me/us:- P:AOPERUCM3883-98 spe.doc-22/11/00 -1A- The invention relates to a protective plug, in particular to an overvoltage protective plug in telecommunications systems. An overvoltage protective plug of this kind may generally include a housing having a printed circuit board, an overvoltage suppressor with a conductive plate, a solder molding which melts if the overvoltage suppressor exceeds a specific temperature, a ground plate, a spring arm which is connected to the solder molding and to the ground plate, and an overcurrent protective element.
DE 44 37 122 C2 has already disclosed a protective plug of this generic type, which comprises a housing having a printed circuit board, an overvoltage suppressor, a solder molding which melts if the overvoltage suppressor exceeds a specific temperature, a slide, a spring, a ground plate and a signaling element, a spring arm which is fitted on the slide.
Coarse protection is achieved in a known manner by an overvoltage suppressor. The fail-safe mechanism linked to 20 the overvoltage suppressor achieves thermal protection in the event of the overvoltage suppressor being overloaded, in that it shorts the telecommunications wires a, b to ground.
This shorting mechanism is achieved by a slide, via which, on the rear of the plug, a red signaling element projects in a clearly visible manner from the plug when an overvoltage occurs.
The tripping of the fail-safe contact is achieved by a solder molding. Via a conductive plate which is welded and clamped on, heating of the overvoltage suppressor causes the solder molding to melt. The solder molding is subject to a RL minimal spring force (compression force) which is accurately balanced, is exerted by the slide and is at the limit of the POPERUJCM~53883-98 spe.doc-22/1 I/00
IB-
slide static friction. The solder molding and the spring force of the slide are largely decoupled as a result of a supporting surface for the slide being in an inclined position. The slide, which is held against the housing by an edge during operation, becomes free from the edge as a result of the melting of the solder molding and because of the spring movement which this releases. The slide is moved to the rear by a compression spring which is mounted on it and is supported on a housing inner wall.
A red plastic part is arranged as a signaling element on the slide in the rear region of the plug such that, when the slide moves to the rear, it pivots out of the plug and indicates tripping in an easily visible manner.
In a number of applications, it is desirable to replace mechanical signaling of tripping by electronic means and to use reversible overcurrent protection in order to avoid replacement of fuses and/or the plug.
Embodiments of the present invention aim to provide a protective plug for reliable protection against 20 overvoltages, in which the switching contact is designed in a simplified manner and automated manufacture with low costs is ensured.
*oo .o P:AOPERUCMU3883-98 sp.doc-22/11/00 -2- In particular, the present invention provides a protective plug, in particular an overvoltage protective plug for use in a telecommunications system, comprising a housing having a printed circuit board, an overvoltage suppressor with a conductive plate, a solder molding which melts if the overvoltage suppressor exceeds a specific temperature, a ground plate, a spring arm which is connected to the solder molding and to the ground plate, and an overcurrent protective element, wherein the spring arm is formed by a bent switching contact on which the solder molding is arranged, which solder molding is moved into contact, before tripping, with the ground plate and with the conductive plate and, after tripping, is additionally moved into contact with telecommunications lines of the telecommunications system.
Simplification of the switching contact (fail-safe mechanism) ensures reliable tripping and uncomplicated assembly which can be automated.
20 Designing the conductive plate separately from the overvoltage suppressor allows overvoltage suppressors from different manufacturers to be used without having to carry o• out any design changes.
The use of temperature-dependent resistors for overcurrent protection, whose connecting wires are cut and bent to size such that it is possible to fit them on the printed circuit board axially, ensures reversible overcurrent protection, that is to say the plug remains serviceable in this context after a tripping process.
P:OPERUCM\~3883.98 spe.doc-22/1 1/00 -2A- The protective plug can be populated using SMP technologies.
Further advantageous refinements of the invention are contained in the dependent claims.
The invention will be explained in more detail in 3 the following text with reference to an exemplary embodiment of a protective plug which is illustrated in the drawings, in which: Fig. 1 shows a section side view illustration of the open protective plug, Fig. 2 shows a side view of the switching contact in the non-tripped state and in the tripped state, Fig. 3 shows a perspective illustration of the switching contact, and Fig. 4 shows a perspective illustration of the conductive plate.
The protective plug is provided in particular as an overvoltage protective plug for use in telecommunications systems in conjunction with isolating blocks and connecting blocks and provides protection against transient overvoltages and inductive currents.
The protective plug comprises fail-safe coarse protection and current protection in the form of a reversible 20 protective element. Furthermore, the protective plug has contact surfaces, with which contact can be made using an instrument lead. In this case, contact is advantageously Smade with the telecommunications lines a, b 0simultaneously. If an overvoltage occurs, for example if local power supply voltages (up to 220 Vrms) touch the telecommunications lines a, b, they are shorted via a switching contact (fail-safe mechanism).
Fig. 1 uses a side view of the open plug to show the major components of the protective plug and their physical relationship.
According to the illustration in Fig. 1, the protective plug comprises an outer housing 1, whose underneath is sealed by a printed circuit board 2 with a conductive plate 9, with an overvoltage suppressor 3 and with overcurrent protective elements 7, a switching contact 4 with a solder molding 5, and a ground contact 8. The protective plug is connected via the ground contact 8 to the ground rail (not illustrated) of a connecting strip (not illustrated) and, via it, to the 4 ground for the protective system.
The contact plate 10 (Fig. 3) of the switching contact 4 is connected via the ground contact 8 to ground and via the solder molding 5 to the conductive plate 9 of the overvoltage suppressor 3. When the overvoltage suppressor 3 is heated, heat is passed via the conductive plate 9 to the solder molding 5. The switching contact 4 is moved from the non-tripped position I with its two contact vanes 11, 11' (Fig. 3) onto two contact surfaces (not illustrated) on the printed circuit board 2 (Fig.
The contact surfaces on the printed circuit board 2 are both contact points for the telecommunications wires a, b (not illustrated). The wires a, b are connected to ground via the contact vanes 11, 11' arranged on the 15 switching contact 4.
Current protection is ensured by the SMD elements 7 (Fig. with which contact is made via solder pads on the printed circuit board 2 (not illustrated).
Fig. 2 shows a side view of the switching contact 20 4 connected to the solder molding 5 and connected to the ground contact 8, the latter being functionally connected to the conductive plate 9 and to the overvoltage suppressor 3. The switching contact 4 operates as a failsafe contact and is physically designed such that it essentially represents a component bent in a semicircular shape which, in the tripped state II, still has sufficient spring force to ensure the necessary contact forces for the connection to the ground contact 8 and to the telecommunications lines a, b.
According to the illustration in Fig. 3, the switching contact 4 has two contact limbs 6, 6' which are bent laterally from the contact plate 10 and are used as stand legs for defined points for the switching contact 4 in the housing 1. The contact limbs f, 6' each have a stud 13, 13' to avoid them being pulled out of the housing recesses. The contact plate 10 acts as a third stand leg in the housing 1 and as a contact for the ground contact 8. At the other end of the switching contact 4, the two contact vanes 11, 11' are formed with i contact claws 12, 12' symmetrically with respect to the centrally arranged solder molding 5, and these contact claws 12, 12' are angled downwards, make contact, in the tripped state II, with the contact surfaces (which are located in the signal path) on the printed circuit board 2 and thus short the telecommunications lines a, b to ground and dissipate the overcurrent. The solder molding in the center between the contact vanes 11, 11' is a cylindrical solder pellet which, once assembly has been completed, is positioned on the conductive plate 9 of the overvoltage suppressor 3.
If the telecommunications lines a, b touch any power supply voltages, the overvoltage suppressor 3 is **.**triggered first and dissipates the current to ground. If 15 this defect continues, it and its environment are heated and, via the permanent connection to the conductive plate *e 9, heat radiation and heat conduction cause the solder pellet 5 to melt and the switching contact 4 to trip.
Assembly of the protective plug can be automated.
S. 20 All the individual parts are designed such that they can S. be assembled manually or by a production line.
The iground contact 8 is made contact with from the front by horizontal insertion in the housing 1. In this region, the housing 1 and the ground contact 8 are designed such that the ground contact 8 makes contact with the known ground rail (not illustrated) The housing 1 fitted with the ground contact 8 is used in such a manner that the open underneath of the housing points upward. The switching contact 4 is adjusted from above, in openings located in the housing 1, such that the solder molding 5, which is, for example, riveted to the switching contact 4, points upward.
In order to complete assembly, the printed circuit board 2 fitted with the conductive plate 9, the overvoltage suppressor 3 and with two overvoltage protective elements 7 is latched onto the housing 1 with the component side underneath, the printed circuit board 2 being held with the plug contact surfaces in the direction of the housing apex. Latching essentially takes 6place to the long sides in the rear region of the printed circuit board 2 (not illustrated). A further, small latching hook is located in the front region of the housing apex.
All the electronic components are soldered to the printed circuit board 2 using a reflow soldering process.
According to the illustration in Fig. 4, the conductive plate 9 is the first item placed on the printed circuit board 2 after it has had solder paste applied. In this case, two lugs 14, 17 on the conductive plate 9 latch into corresponding cutouts in the printed circuit board 2. This results in the overvoltage suppressor 3 being positioned accurately. After this, the overvoltage suppressor 3 is clamped into the conductive 15 plate 9 (which is coated with solder paste) between two holding lugs 15, 15' and 16, 16' in each case, such that the latter rest against electrically non-conductive "sections of the overvoltage suppressor 3. The overcurrent protective elements 7 are placed on the pads provided for 20 this purpose on the printed circuit board 2. The commercially available axial components are prepared in advance suc h that their connecting wires are cut to length and bent such that they can be used as SMD components. All the components are soldered to the printed circuit board 2 using the reflow soldering process and, at the same time, a soldered joint is produced between the base part 19 of the conductive plate 9 and the overvoltage suppressor 3.
The reference numerals in the following claims do not in any way limit the scope of the respective claims.
P:OPER'JCM\53883-98 spedoc-22/ 11l00 6A Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
