Abstract
Description
- The present invention relates to those electrical connectors of the type with two bodies provided with clamping elements fit to clamp the main conductor and the secondary conductor to electrically connect one to the other. Such connectors are usually used as shunt, junction or terminal elements for insulated or naked multiple or single-wired conductors.
- Some connectors are known, a body of which is provided with a first and a second series of teeth or metallic top lands electrically connected among them. To the above described body another body is clamped, by suitable means, provided with insulated elements, for example plastic material, in such a way that a main conductor is laid down between the first series of teeth and the insulated elements of the second body and so likewise the derived conductor is laid down between the first body second series of teeth and the further insulated elements provided on the second body. Obviously the second body insulating elements are set in proper position, in such a way that when the second body is clamped on the first, such insulated elements come to set out in correspondence with the first and the second series of metallic teeth respectively. By virtue of said electrical connections between the first and the second series of teeth, the electric current of the main input conductor into connector is transmitted to the derived conductor.
- These prior art connectors, however, present the disadvantage that, when clamping the two bodies one against the other, the interposed conductors, both naked and insulated, suffer a damaging, this being due to the insertion of said teeth into the very conductors and / or their insulation.
- Purpose of the present invention is that of eliminating the above said inconvenience providing some clamping elements of the conductors that shall show the following advantages:
- would allow the application of any clamping effort without the conductors both naked and insulated shall suffer damagings, keeping a resistance to tensile stress very close to their rated ultimate tensile strength;
- could be used for conductors having different sections, ensuring a perfect self-centering; -shall be constructively economic and shouldn't require servicing interventions. - The purpose and the above listed advantages are obtained by the application to the electrical connectors of clamping elements, each formed by a pair of properly curved sectors into which are placed the con ductors, without these being damaged when the connector bodies are clamped one against the other.
- Further features and advantages will result evident from the following detailed description of a preferred but not exclusive form of the invention illustrated for a merely exemplifying purpose and not limitating of the enclosed figures where:
- FIGURE 1 represents the front view of a connector with the subject pairs of curved sectors;
- FIGURE 2 represents a plan view of the connector lower body of Fig. 1;
- FIGURE 3 represents in enlarged scale a pair of such sectors;
- FIGURE 4 represents the section along the line IV-IV of the detail of Fig.3; and
- FIGURE 5 represents in section a variant made up by two parallel pairs of sectors.
- In Figg. 1 and 2, is shown, as an example, an electrical connector formed by two
bodies 1 and 2, provided respectively withtongue 3 that goes to insert intoslot 4 when the two bodies are mounted one against the other, clamping themain conductor 5 and the derivedconductor 6 by means ofclamping elements 7. Saidbodies 1 and 2 are clamped one against the other by screwing the nut 8 on the screw 9 provided by the head 10 placed below the body 1. The screw 9 is through across ahole 11 made intobodies 1 and 2, as one can see in Fig. 2. - The conductors may be indifferently naked or insulated. For example in Fig.2 the
conductors sheath 12. - The
elements 7 consist of theparts body 2 consist each of a pair ofcurved sectors 14 tapered blade-shaped on the side where they receive theconductors elements 13 in a way such as to clamp to perforation the conductors between the pairs of curved 14 sectors respectively ofparts - The
metallic elements 15 in contact respectively with theconductors conductors 16, as illustrated in the Figg.1 and 2. - As a variant, only one of the
elements element - Preferably, the elements made of plastic 13 material are machined enbloc with their
own body 2 formed of plastic material by the die-casting technique. As above said, once theconductors bodies 1 and 2, the nut 8 is tightened by an usual spanner in such a way as to occur the tightening of the above saidconductors elements 7. -
Said sectors 14 have a curving radius suitable to the various dimensions of the conductors and tapered in blades-shape for not damaging the conductors and for their perfect self-centering. - Finally each
sector 14 both of metal and of insulating material, is slightly spaced from the adjacent sector by anentity 17, as one can see in Fig. 3. - Changes of practical and constructive nature may be brought to the invention without because of this going out of the range of the present invention as it is claimed below.
