MOUNTING COMPONENTS ON PRINTED CIRCUIT BOARDS
This invention relates to the mounting of components on printed circuit boards and to the interconnection connection of such components as required to function with the circuitry provided upon the printed circuit boards.
In particular, the present invention is concerned with facilitating the production and subsequent use of apparatus requiring the use of a printed circuit board and of a number of components required to be mounted to the board that require the connection thereto of electrical inputs additional to those forming part of the actual circuitry provided upon the printed circuit board.
More particular1, but not exclusively such apparatus can involve the use of components that in use require the provision of a heat sink or heat sinks to disperse heat generated by the components when in use.
One such form of apparatus using such heat generating components mounted to a printed circuit board can, for example, form a current phase control apparatus.
Current phase control apparatus can as indicated incorporate a printed circuit board which provides the mounting support or chassis equivalent for all of the major components of the phase control apparatus such as current transformers, torroids, capacitances, and heat sinks. In practice, with known phase control apparatus, the electrical connections between such individual components mounted to the printed circuit board and any voltage/current supplies to the apparatus involves a complexity of individual wires involving numerous soldered or similar permanent connections. In practice, such forms of permanent connections not infrequently introduces an inconvenient jumble of
<Desc/Clms Page number 2>
interconnection wires at various locations of the printed circuit board which can in practice introduce inherent servicing problems particularly when a component is required to be changed by reason of it having become defective or perhaps for the purposes of effecting an up-grading component in its place
It is an object of the present invention significantly to reduce such inherent difficulties arising in connection with the mounting of components to printed circuit boards.
It is a further object of the invention to increase the capability of a printed circuit board to mount components thereupon.
Broadly, according to a first aspect of the present invention there is provided in apparatus involving a printed circuit board means whereby external operational connections to one or more of any components mounted to the printed circuit board are by way of pluggable connectors.
In accordance with a further aspect of the invention in apparatus incorporating a printed circuit board those components provided upon the board in addition to the circuitry layout are locatable upon both sides of the board.
Broadly, according to a further aspect of the present invention there is provided electrical apparatus incorporating a printed circuit board and a plurality of components mounted thereupon, wherein mechanical/electrical connections between the components, the board and logic and power sources are formed by plugable connectors.
Preferably, where electrical connections are required for components mounted to a printed circuit board the connections are effected by push-on connections,
<Desc/Clms Page number 3>
thereby eliminating the use of wire connections and consequential soldered or like attachment of the wires.
In accordance with a further aspect of the invention there is provided electrical apparatus incorporating a printed circuit board, wherein mechanical/electrical connections between the printed circuit board and logic and power connections for the printed circuit board are formed by plugable connectors, and wherein an insulator component incorporating a plurality of sockets for and supporting said plugable connectors is adapted for mounting to the printed circuit board in such manner as to provide appropriate electrical clearance for the circuitry of the printed circuit board.
Preferably, the insulator component is provided with a locating and retaming region for receiving a heat sink arrangement forming part of said circuitry, and wherein the insulator component is adapted to receive and mount a thermal sensor device in such location that operational contact is made with the heat sink.
For a better understanding of the invention and to show how to carry the same into effect reference will now be made to the accompanying drawings which very schematically illustrates phase control apparatus incorporating features of the invention and in which :- Figure 1 schematically illustrates an side view of apparatus including a printed circuit board and incorporating the concepts of the present invention; Figure 2 is a plan view of the apparatus shown in Figure 1 ; Figure 3 is an end view of the apparatus illustrated in Figures 1 and 2; Figure 4, schematically illustrates in perspective view a multi-socket printed
<Desc/Clms Page number 4>
circuit board insulator for interpositioning between a printed circuit board and certain components of the apparatus shown in Figures 1 to 3 Figure 5 is a schematic representation in end view of a plugable connector for use with the apparatus of Figures I to 3; and
Figure 6 is a side view of the connector of Figure 5.
Referring now to the drawings and more particularly to Figures 1 to 4 the apparatus shown therein includes a printed circuit board 1 upon which is mounted an insulating component 2. The component 2 includes, on the surface 3 thereof that provides its upper surface when mounted to the printed circuit board 1, along one longer edge region 4 thereof a group of four rectangular walls defining locating sockets 5, 6,7 and 8 for mounting electrical connection plugs 9 (Figures 5 and 6) to be described in detail hereinafter. Two further similar rectangular walls define two further sockets 10 and 11 at positions on the board located along an edge region 12 thereof that is parallel to the edge region 4. Intermediate these two groups of sockets there is provided a further rectangular wall-like structure 13 which defines a rectangular recess for receiving and locating a heat sink 14 In addition, the formation of the structure 13 defines a secondary recess or region 15 adapted to receive and mount a thermal sensor device 16 in such location that operational contact is made with the heat sink 14 when mounted in the insulating component.
In addition to the sockets for the connectors 9, a series of spade connectors 17 is located along one end 18 of the printed circuit board 1, whilst a multiway, i. e., twelve way, connector socket 19 is provided at the edge region 20 of the printed circuit board. These connection arrangements can conveniently be regarded as being of the type conventionally provided on printed circuit boards for the connection of supply voltages and currents and input and output signals to the printed circuit board circuitry.
<Desc/Clms Page number 5>
It will be appreciated that a printed circuit board incorporates a circuit layout including various electrical components together with circuit connection paths and integrally associated relatively small components such as resistors and capacitances electrically interconnected by printed connection paths as are commonly associated with printed circuit boards and which are all operationally interconnected as an integral part of the printed circuit board layout and construction. In situations where additional components are required for the operation of the circuitry these components are separately mounted conventionally to the upper surface of the printed circuit board.
As has been mentioned the provision of such additional components introduces the need for a plurality of interconnecting wires and associated permanent connections. One such form of apparatus is current phase control apparatus that, depending upon the magnitude of the currents involved, involves the mounting of relatively larger ancillary components to the printed circuit board. Since in the case of a current phase control apparatus these ancillary components can be relatively physically large it may not be possible for all of the components to be mounted to one side of the printer circuit board. In accordance with the invention such components are mounted to both sides of the board at the locations provided therefore in the layout design of the printed circuit board. Such locations are in general at the most electrically appropriate operational positions having regard to the circuitry provide upon the printed circuit board. To accommodate these additional components the printed circuit boards are provided with the appropriate electrical connections from the component to the printed circuit board which lead to predetermined electrical connections regions on the board. Conventionally, where possible, such connection regions are only provided on the upper side of the printed circuit board when in use.
This clearly limits the number of components that can be mounted to a printed circuit board.
<Desc/Clms Page number 6>
To avoid such constraints as will be noted from the Figures 1 to 3 with the proposals of the invention components such as capacitors 21, current transformers
22, additional connector arrangements 23, etc, are schematically illustrated as being mounted to both of the sides of the printed circuit board
Conveniently, the current transformer 22 is mounted over the connector arrangement 23 as the latter is position at the location at which contact breaker plugs provided upon the current transformer are normally connected to busbars or power cables (not shown). That is to say the current transformers are mounted at the plug interface of the contact breaker to the printed circuit board junction.
Referring now to Figures 5 and 6, these Figures schematically illustrate a construction for a pluggable connector 9. The plugs incorporate a main body 24 to which a cable end (not shown) may be connected to prevent relative movement between the cable end and the plug, and an array of resilient members 25 that are intended to engage with the side walls of the insulator component to hold the plug in place and which effectively electrical contact the actual electrical connection part (not shown). In addition, the body is provided with appositely directed spring members 26 adapted, when the plug is fitted to engage in complimentary recesses 27 provided in the associated insulator socket wall.
Conveniently the plugs 9 can be formed from a plug adapted to suit printed circuit board mounting, For example, by removing a crimped section conventionally provided for cable attachment and then reforming the remainder of the plug effectively to produce the array of resilient members 25 and thus the arrangement shown in the figures 5 and 6.
Since as is well known components associated with printed circuit boards often generate significant amounts of heat that needs to be displaced to avoid heat damage to the printed circuit board or components mounted to the board it is
<Desc/Clms Page number 7>
known to provide heat sinks at a location closely adjacent to heat producing component or components.
Since heat sinks are commonly formed from Aluminium they are electrically conductive and must therefore be electrically insulated from the printed circuit board layout, etc.
In the Figures 1 to 3 the previously discussed insulating component 2 provides the requisite electrical shielding the heat sink 15 from any electrical contact with the printed circuit board and any associated electrical components whilst enabling the heat sink to be located as close as possible to the heat source or sources from which it is required to dissipate heat.
In addition to this particular function the insulating component by reason of the provision of the sockets 5,6, 7,8 10 and I I provides physical support for mounting the connectors 9. It will be appreciated that the design of the printed circuit board layout and that of the insulating component is designed to facilitate the positioning of the pluggable connector sockets and associated electrical connection of the printed circuit board in that said component connection locations on the printed circuit board will positionally align with the socket positions on the insulating component when mounted.
With a view to constraining, in the event of an electrical breakdown of a component mounted to the printed circuit board, debri that may be created by the said electrical breakdown of a component a blast accommodating box or the like 21iN is interposed between the printed circuit board I and any components mounted thereupon.
It will thus be apparent that the insulator component 2 serves to provide six sockets for receiving up to six electrical connectors 9 in a generally geometrically square relationship and such that the connectors are vertically upstanding. In
<Desc/Clms Page number 8>
practice this arrangement of the sockets facilitates the application of requisite electrical inputs to the printed circuit board and to any components mounted to the printed circuit board in such manner the formation of an array of permanently connected connection wires, etc. , to the components.
As a result of the provision of the insulator component 2 with its connector sockets it will be apparent that all external current/signal interfacing to the printed circuit board components is by way of the pluggable connections so that the printed circuit board assembly is essentially a wire free installation.
It will be understood that the dimensions and particular shape of the insulator component 2 will be appropriate to the nature of the associated printed circuit board. so that the various sockets provided upon the insulator component are correctly positioned with respect to the layout of the printed circuit board thereby to ensure that the connectors are able to make the requisite direct electrical connections with the printed circuit board.
As will be appreciated since all power and logic electrical interconnections between components and the chassis and board are made using the above mentioned plugable connectors it will be appreciated this facilitates installation and the servicing of the apparatus in that it is not necessary individually to connect or disconnect individual wire connections conventionally made to a component, possibly in positions where access to a connection point is awkward and in consequence the operations involved in connecting or disconnecting individual wires could result in damage to adjacent components.
The arrangement of the insulator board and its associated printed circuit board has been found suitable for a wide range of for example phase control units suitable for controlling the current from single phase alternating current supply. For example, units involving currents 20 to 100 Amps.
