Abstract

A quick connector for armoured resistance elements, characterised by comprising: a female element (2) formed from a cylindrical sleeve (6) which extends at one end into means (8, 10) for retaining a conducting cable (18) and internally comprises a rib (12), and a male element (4) consisting of the projecting portion of the terminal pin (11) present on each end of the armoured resistance element and comprising a groove (16) engaged by said rib (12) when the male element and female element are coupled together.

Description

IMPROVED QUICK CONNECTOR FOR ARMOURED RESISTANCE ELEMENTS
This invention relates to an improved quick connector for armoured resistance elements. Armoured resistance elements are known consisting of a resistive electrical conductor housed in a rigid sheath generally of stainless steel and separated therefrom by a dielectric substance such as magnesium oxide in granular form.
Traditional connecting blades are soldered to the conductor ends which emerge from the sheath, for engagement in corresponding push-on connectors clinched to the feed cables.
The push-on connector is generally holed and ribbed to provide effective mechanical coupling.
Because of the large contact surface provided by the connecting blade, this connector low specific current on the terminals, so preventing excess heat development which by melting the material could compromise the continuity of the electrical connection, and prevent its accidental separation as a result of thermal expansion and/or vibration.
These connection systems present however the drawback of time lost in soldering the blades to the ends of the conductor and a resultant product which is not always reliable qualitatively as the blades can become detached during transport and storage of the same conductor.
An object of the invention is to eliminate these drawbacks by an improved connector of easy construction which allows effective mutual coupling of the two terminals to be connected together while at the same time preventing their accidental separation. This object and further ones are attained according to the invention through an improved quick connector for armoured resistance elements as described in claim 1.
This invention is described in detail hereinafter with reference to the accompanying drawings, on which:
Figure 1 is a front view of the female element of the invention, Figure 2 is a side view thereof, Figure 3 is a plan view thereof,
Figure 4 is a cross-section therethrough on the line IV-IV of Figure 1 , Figure 5 is a side view of the male element of the connector of the invention, and Figure 6 shows the assembled connector.
As can be seen from the figures the quick connector of the invention comprises substantially a female element 2 and a male element 4 to be coupled to it. The female element 2 is constructed generally of nickel-plated iron, steel or copper, and is formed by punching and bending a flat portion to form a longitudinally split cylindrical 6 which extends axially into a first pair of fins 8 which themselves extend into a second pair of fins 10 of greater length.
The sleeve 6 has an inner diameter equal to the outer diameter of the end of the terminal pin 11 of an armoured resistance element 13 and comprises internally a semicircular rib 12.
The length of the sleeve 6 is such as to provide a contact surface area which results in specific currents typical of a blade-type connector.
The male element of the connector consists merely of the projecting portion of the terminal pin 11 present on each end of the resistive conductor housed in the metal sheath 14 of the resistance element 13. This end comprises a circumferential groove obtained by turning or pressing, and spaced from the free end by a length substantially equal to the distance between the rib 12 of the sleeve 6 and that end thereof connected to the first pair o fins 8. In using the quick connector, a portion of insulation is removed from the end of the cable 18, its bared wire then being interposed between the first pair of fins 8, which are then bent inwards one on the other to securely retain the cable wire. In the same manner the second pair of fins are bent inwards to retain the cable insulation sheath. The terminal pin of the armoured resistance element is then inserted into the female element prepared in this manner so that the rib 12 engages in the groove 16 thereof, so providing both electrical contact and a stable mechanical connection.
