GONE COUPLING FOR ELECTRICAL CALES.
Application med November 2, 1,925. seriai No. ee,343.
This invention relates to a coupling for the terminals of electrical conductors and is directed to a permanently formed unit with which elements designed to be connected to the terminals of the electrical conductors are arranged to interlock to prevent separation.A
. The invention particularly includes a body ot hollow form with a central transverse partition, the body beyond the partitionl being interiorly of conical -'formation toward the free ends. Ferrules of exterior conical formation are designed to be interitted with the terminals of the electric conductors, these errules being adapted to be passed into the conical housings of the bodyI and transversely expanded to prevent the :terrules and thereby the connected terminals from being withdrawn from the body.
The invention is illustrated in the accompanying drawings, in which:
Figure 1 is a view in elevation of the errule used with the body.
Figure 3 is a similar view showing the errule in one housing in expanded relation and the ferrule in the other housing interlocked with the housing under endwise pull on the connector.
Figure 4 is a longitudinal sectional view of the errule.
Figure 5 is anend view of the ferrule.
The improved coupling comprises a body 1 of hollow form divided by a transverse partition 2 which, as it serves merely as an abutment for the ferrules, may be of any and is formed with additional slots 6 extending through the larger end of the ferrule and terminating short of the smaller 55 end to thereby provide for the expansion and contraction of the ferrule, particularly at`the4 larger end. It is to be noted that t-he smaller end of the ferrule constitutes practically a sharpened edge.
1n use, the smaller end of the fel-rule is introduced between the exterior covering 9 and the conductor 8 of the Wire terminal and the errule and connected wire terminal are introduced into one of the housings. It is to be understood that the larger end of the ferrule is of such diameter relative to the diameter of the smaller or entrant end of the housing as to just permit the introduction of the ferrule therethrough. The.70 ferrule and partially connected end of the conductor are introduced into the housing until the larger end of the ferrule engages the partition or stop 2, following which end- Wise pressure is continued on the conductor, serving by means of the external sheath and the spreading action of the ferrule incident to the difference in diameter of the conductor 8 and the normal interior diameter of the ferrule to so increase the exterior diam- 8o eter of the ferrule, particularly at the larger end, that on endwise movement of the connected ferrule and conductor toward the reduced end of the housing, the errule is prevented from passing through the smaller end of the housing, thus constituting an in. terlock between the ferrule and housing. With a conductor introduced into each housing, the body 1 constitutes a coupling between thev conductors, preventing their endwise separation and maintaining their electrical continuity.
Having` now described and ascertained the nature of my said invention and the manner in whichv the same is to be performed, what o5 I claim is:
In a coupling, a body having a central transverse partition and being formed bevond the partition to provide conical housings of permanent 'form with their larger 10o ends next the partition and their smaller ends open, in combination with a conical ferrule divided longitudinally to permit expansion and formed with an interior bore of uniform diameter, the larger end of the conical ferrule being slightly less than the diameter of the openin leading to the housing, whereby the ferru e may be passed into the housing through said open end, said ferrule being designed to be introduced into a wire terminal between the wire and insulating coverin while the ferrule is within the housing, t e excess thickness provided by the insulation preventing the Withdrawal l0 of the ferrule through the opening of the housing.
