SPECIFICATION
Improvements in or relating to electrical connectors and components including said connectors
The present invention relates to improvements in or relating to electrical connectors and electrical components including said connectors.
The invention concerns especially but not exclusively connectors of the type known as l.D. connectors, that is insulation displacement connectors. Such connectors will be referred to hereinafter as 'I.D. connectors'. In such connectors there is no need to strip the insulating covering from a conductor wire prior to connecting it to the connector as the connector is so designed that it displaces or cuts through the insulation to make electrical contact with the electrical conductor when the insulated conductor is pressed into it.
Connectors of this type are known; according to the present invention they are incorporated by novel and ingenious means in various electrical components.
A first aspect of the present invention provides a lamp holder incorporating l.D. connectors and including a diode to be connected in series with a lamp held in the holder.
According to this aspect of the present invention there is provided a lamp holder including a casing of an insulating material, two electrically conducting contacts for receiving and retaining a lamp, means for retaining and holding a diode, and I.D. connector in electrical connection with one lamp contact, an l.D.
connector adapted for electrical connection with one lead of said diode, and an electrical connection adapted to connect the other lead of the diode to the other lamp contact.
Preferably the contacts, connectors and connections are manufactured from phosphor bronze.
Preferably the l.D. connector in electrical contact with the one lamp contact is formed on an extension from said lamp contact. It is accommodated in a passage in the casing and retained therein by a resilient tongue engaging in a recess in the casing. The l.D. connector may include two conductor receiving slots, each slot being located in a side upstanding from a base which carries also said tongue, and prongs of said lamp contact.
Preferably the l.D. connector adapted for connection with said one lead of the diode is formed by a conductor receiving slot formed in a lateral extension from a base member from which extends two sides each including conductor receiving slots to form said l.D.
connector for said other conductor. The base member includes a resilient tongue for locating and holding the connector in the casing.
Preferably the l.D. connector adapted for connection with the said other lamp contact is formed on a lateral extension from said lamp contact and includes a conductor receiving slot. The base may include a connector locating and holding tongue and the prongs of said lamp contact are preferably formed on said base member.
Preferably the casing is provided in those areas where the l.D. connectors for the conductors project beyond the body of the casing with a sleeve having at its end surrounding the connector two pairs of mutually axially spaced inwardly directed conductor retaining means. Each of said means may include a resilient finger defining a gap between it and the other finger of the pair, the gap dimension being less than the external diameter of the conductor so that after a conductor has passed through the gap it is retained in the connector.
Preferably the fingers of one pair are laterally spaced with respect to the fingers of the other pair such that the insertion blade of the conductor insertion tool may pass therebetween.
Preferably the casing includes mounting means for holding the lamp holder in a supporting structure. The mounting means may be resilient arms with catches on their free ends.
A further aspect of the present invention resides in a connection for connecting a diode to an electrical conductor where, for example, a branch incorporating a diode is led from a conductor or for providing a spade connection leading from the conductor.
According to this aspect of the invention the electrical connection comprises a substantially U-shaped member of a sheet-like conducting material incorporating a first slot into which a lead from an electrical component can be inserted and trapped and a pair of corresponding slots into which a conductor can be inserted and trapped to form an l.D. connector.
Preferably the member is manufactured from phosphor bronze.
Preferably said first slot is formed in the base of said U and each of said limbs of the
U includes a slot for the conductor. Preferably each slot has an outwardly admitting opening mouth. Preferably each limb of the U has a locating tongue for locating and fixing the connector in an electrically insulating casing.
Preferably the casing has means for locating the electrical component. The electrical component may be a diode having its other lead extending into a passage in the casing adapted to receive a spade connector. Alternatively it may be a connection wire extending from said first slot into said passage in the casing.
Preferably the casing has conductor retaining means comprising a sleeve having at its end surrounding the connector two pairs of mutually axially spaced inwardly directed conductor retaining means. Each of said means may in dude a resilient finger defining a gap between it and the other finger of the pair, the gap dimension being less than the external diameter of the conductor so that after a conductor has passed through the gap it is retained in the connector.
Preferably the fingers of one pair are laterally spaced with respect to the fingers of the other pair such that the insertion blade of the conductor insertion tool may pass therebetween.
A further aspect of the present invention relates to an electrical connection of the spade and receptacle type. A spade and receptacle connector is used to joint two conductors together in an electrically conducting manner, one end of one conductor having a rectangular flat spade-like member fixed to it which, to make a connection with another conductor, is pushed in its axial direction into a receptacle, the receptacle including a base having side lugs extending over the top of the base to accommodate and trap the spade between the lugs and against the base.
According to the present invention there is provided a receptacle for a spade and receptacle connection including a base and side lug members for trapping a spade between themselves and the base, the base having a rearward extension on which is formed an l.D.
connectors.
Preferably the receptacle is formed from phosphor bronze.
Preferably the l.D. connector comprises two side members upstanding from the lateral edges of the base extension and each including an axially extending slot of width substantially equal to the diameter of the conducting core of the electrical conductor to be held therein, a wire admitting mouth being provided at the entry to each slot.
Preferably a suitably shaped insulating sleeve of a resilient non-conducting material surrounds the receptacle and the l.D. connector, the sleeve having at its end surrounding the connector two pairs of mutually axially spaced inwardly directed conductor retaining means.
Each of said means may include a resilient finger defining a gap between it and the other finger of the pair, the gap dimension being less than the external diameter of the conductor so that after a conductor has passed through the gap it is retained in the connector.
Preferably the fingers of one pair are laterally spaced with respect to the fingers of the other pair such that the insertion blade of the conductor insertion tool may pass therebetween.

A receptacle is formed, by punching and shaping from a sheet of electrically conducting material, for example phosphor bronze, a base member 10 having side lugs 12 upstanding from each side thereof, the outer end portions of the lugs being deformed back upon themselves such that their free edges 14 face and are parallel to the base 10. The base has two downwardly projecting rectangular tongues 16 pressed therefrom and the region of the base 10 between the tongues 16 and the downwardly facing edges of the lugs 14 is deformed upwardly to form an arch, so that when a spade is pushed into the receptacle it receives lateral guidance at its side from the lugs 12 and is forced into good electrical contact with the arch 18 by the downwardly facing edges 14. The tongues serve to anchor the connector in an insulating sleeve to be described below.
An l.D. connector is formed integrally with the receptacle by extending the base 10 and lugs 12 rearwardly to form a base extension 20 and upstanding sides 22. Each side 22 has an axially extending slot 24 formed therein, the slots extending from the rear edge of the side and being provided with one inwardly converging admitting mouth 26.The width of each slot is less than the outside diameter of the conductor core to which the connector has to be attached by a predetermined amount and it will be realised, therefore, that the width of the slot is less than the width of the outside diameter of the insulation of the conductor so that if a conductor is laid across the end of the connector in the mouths 26 and subsequently pushed axially into the connector in the direction of the slot 24 those portions of the side defining the slot will cut into the insulation so that the slot sides make a gas tight electrical interface- with the conductor to provide electrical connection between the connector and the conductor.
To insulate the connector and receptacle there is provided a sleeve 30 of an insulating material, for example resilient plastics. The sleeve is illustrated in Figs. 2, 5 and 6. The forward section of the sleeve 30 is of hollow rectangular box section and neatly accommodates the base 10 and the lugs 12, the tongues 16 fitting into recesses 17 in the sleeve to anchor the connector in the sleeve. The rear section 34 of the sleeve has an upper and a lower member 36, 38 defining a gap therebetween for reception of the electrical conductor 40 which, as described above, is to be accommodated in the slots 24 of the sides 22. It will be realised, therefore, that the top and bottom members 36, 38 are substantially parallel to the slots 24.
Two pairs of inwardly projecting fingers 42, 44 are provided on the top and bottom members, the first pair 42 being located at the outer end of the members while the inner pair 44 are spaced from this outer end. Both pairs of fingers project towards the interior of the sleeve and are spaced apart by a distance which is less than the outside diameter of the insulated conductor 40. Examination of Fig. 6 will show that a connector 40 can be introduced into the insulating sleeve by springing back the fingers 42 so that the connector can then occupy the space between the outer fingers 42 and the inner fingers 44. In this position the conductor has entered or is about to enter the entrance mouth 26 to the slots 24.
The conductor cannot be readily withdrawn from the insulating sleeve but it has not been trapped in the slots 24 so that a check can be made of the circuitry incorporating the connector prior to final insertion of the conductor and any modifications to the position of the connector on the conductor can be carried out. After such checks have been made the connector can be pushed past the fingers 44 such that it enters the slot 24, the lug sides 22 at this stage cutting through the insulation and causing electrical connection between the conductor and the connector. The fingers 44 will then assist in anchoring the conductor to the connector.
Conveniently this final insertion can be made by a jig and power tool assembly which will be described below.
A connection for connecting a branch to an electrical conductor and providing means for mounting and connecting a diode in the branch is shown in Fig. 7. The connection comprises a connector 110 which is shown in detail in Figs. 8 and 9. The connector is substantially U-shaped in plan, base 112 of the U having first slot 114 extending downwardly from an inwardly converging mouth 116 in its upper edge. The limbs 118 of the U are each provided with downwardly extending slots 120, the slots having inwardly converging mouths 122. Locating tongues 124 are pressed out of and protrude from each limb 118 and serve to locate and position the member 110 in an electrically insulating casing 126 illustrated in detail in Figs. 10 and 11.
One end of the insulating casing 126 is provided with upper and lower members each having resilient fingers which correspond exactly in function but not necessarily in shape and dimensions to the members 36, 38 and fingers 42, 44 described above with reference to Figs. 2, 5 and 6 and as a result they will not be described in detail. It will be realised, however, that by placing a conductor transversely across the insulating casing shown in Fig. 7 and pushing it downwardly between the fingers it will engage in slots 120 and make electrical contact therewith.
The remaining slot 114 is adapted to receive one lead of a diode 128 which is inserted into a receiving recess 130 in the casing 126. The lead of the diode will be deformed on insertion into slot 114 to maintain a gas tight interface. The other lead 132 of the diode is bent backwards on itself and accommodated in a passage 134 extending from the end of the insulating member 126 and located below the diode receiving slot 130, the passage 134 being adapted to receive and hold a spade connector on the end of a conductor of the branch to be connected to the main conductor held in the slot 120.
Figs. 12 to 19 illustrate a lamp holder comprising a moulded casing 210 of an insulating plastics material having resilient mounting arms 212 for mounting the holder in a board.
The base of the casing 210 is provided with outer, intermediate and inner members 214, 216, 218 which are similar to the members 36 and 38 described and illustrated in
Figs. 2, 5 and 6 above and which serve the same purpose, the inner, outer and intermediate members each being provided with two pairs of resilient fingers.
A passage is provided through the casing body and leads from between the inner and intermediate members 218, 216 to accommodate a first live connection which is illustrated in Figs. 14 and 15. The first live connection has a base member 220 formed at its lower end with sides 222, each provided with a conductor slot 224 and terminating in an inwardly converging mouth 226 in the lower edge of the side. A holding and retaining tongue 228 protrudes from the base 220 which extends upwardly to an extension 230 having formed from its sides two resilient prongs 232 which are adapted in use to receive and provide electrical contact with the contacts on the base of a push-fit electric lamp. The prongs are fixed at their base to the extension 230 and are free at their upper ends 234 which are flared outwardly.
It will be realised therefore that a conductor inserted between the fingers of the inner and intermediate members can eventually be trapped in and make contact with the slots 224 to provide an electrical connection with one contact of the lamp to be held in the lamp holder.
The lamp holder incorporates a diode 240 (Figs. 12 and 13) which is located in a diode housing slot 242 formed in the side of the casing 210. Connection with one conductor 246 of the diode is made by an inert connection which is shown in Figs. 16 and 17 of the drawings and which is received in a passage formed in the casing 210 and which extends from between the outer member 214 and the intermediate member 216. The inert connection comprises a base member 250 having sides 252 extending therefrom each side being provided with a conductor receiving slot 254 having a mouth 256. It will be realised, therefore, that a conductor inserted in the manner described above between the fingers of the outer and intermediate members 214, 216 can be accommodated in the slot 254 and make electrical contact therewith.The base member 250 after a transverse extension portion 258 has an upper extension 260 which has a locating tongue 262 protruding therefrom and a lateral extension 270 provided with a slot 274 having a mouth 276, the slot 274 after fitment of the inert connection in the holder 210 receiving the diode conductor 246.
The remaining diode conductor 244 is connected to the second live connection for the bulb, this being illustrated in Figs. 18 and 19.
The second live connection is inserted in a passage in the casing 210 at the side of the bulb holder remote from the first, live connection. The second live connection has a base 280 from which project two lamp contacting prongs 282 which are similar to the lamp contacting prongs 232 described with reference to Figs. 14 and 15 and as a result they will not be described in further detail here. The base 280 has a protruding locating tongue 283 and a lateral projection 281 at its base, the projection incorporating a slot 284 having a mouth 286 which, in use, is intended to accommodate the other conductor 244 of the diode 240.
It will be realised, therefore, that after fitting the two live connections and the inert connection shown in Figs. 14 to 19 to a lamp holder casing 210 a diode can be readily fitted, and by means of a jig and tool assembly its conductors can be fitted to the second connection and the inert connection. Conductors can be fitted between the outer and intermediate and inner and intermediate members to provide contact in the first instance with one side of the diode and in the second instance with one of the contacts for the bulb, the other contact for the bulb making connection with the other conductor of the diode by means of the second live connection. As before, a tool can be utilised to insert the two conductors into the first live and the inert connections.
