INSULATING CONNECTOR FOR WIRES Filed May 1,. 1941 INVENTOR Mike Vara ATTO R N EY Patented Sept. 15, 1942 UNITED STATES' PATENT OFFICE 4 Claims.

This invention relates to new and useful improvements in an insulating connector for wires.

More particularly, the invention purposes the construction of a connector as mentioned, capable of tightly connecting wires together in a simple way.

More specifically, the invention proposes to characterize the connector by a tubular housing having a closed end and adapted to receive group of wires into its open end, and a simple novel arrangement for holding the inner ends of these wires connected together.

More specifically, the invention contemplates providing a metallic sheet turned around the end portions of the wires and acting in a certain way in conjunction with portions on the tubular housing for forming the desired connection,

Still further it is proposed to form one of the wires at its inner end with a loop engageable with a complementary longitudinally extending groove formed on the inside of the tubular housing in a manner to prevent the wires from turning relative to the tubular housing.

Another object of the invention is the construction of a device as mentioned which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth,

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a perspective view of an insulating connector with wires constructed in accordance with this invention.

Fig. 2 is a vertical sectional view of Fig. 1.

Fig. 3 is a partial sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a, horizontal sectional view taken on the line 44 of Fig. 3.

Fig. 5 is a perspective view of the metallic sheet used in the connector.

Fig. 6 is a view similar to Fig. 2 but illustrating a modification of the invention.

Fig. '7 is a vertical sectional View taken on the line II of Fig. 6.

Fig. 8 is a perspective view of the inner ends of the group wires.

Fig. 9 is a perspective view similar to Fig. 8, but illustrating a group of wires made of three wires. 4

The insulating connector for wires, in accordance with this invention, includes a tubular housing I0 having a closed end II and an open end I2. The housing III is also provided with an internal longitudinally extending groove I3 extended inwards from its open end I2. The housing III also has an external head It) by which it may be conveniently gripped. A group of wires I4, I5 have one of their ends twisted together forming a coil I6. More specifically, the wire I4 forms the core of the coil I6 while the wire I5 is wound around this core portion. The Wires I4 and I5 have insulating covering material M and I5 respectively, along their length except at the twisted end portion. The wire I4 has its free end formed into a loop portion I'I.

When the engaged ends of the wires I4 and I5 are inserted into the tubular housing the loop I! will have its top (see Fig. 2) disposed with the groove I3 to prevent the wires from turning relative to the tubular housing II).

A metallic sheet I8 is turned around the twisted ends, that is, the coil I6 of the wires I4 and I5. The metallic sheet I8 is formed from a piece of sheet metal bent substantially into tubular shape. A clamping member 20 is mounted on the housing II! and abuts against the metallic sheet I8 for holding said sheet and the coil I6 of the wires I4 and I5 in position. More specifically, this holding member 20 comprises a screw of insulation material mounted through one wall of the housing III.

With the parts as illustrated in Fig. 2 the wires I I and I5 are electrically connected together and securely held within the casing IB.

If desired, the wires I4 and I5 may be removed by first loosening the screw 20 and then pulling out on the wires. The metallic sheet I8 may then be slightly opened to permit its being slipped off the coil I6.

In Figs. 6' and 7 a modification of the invention is illustrated which is similar to that previously described except that a metallic sheet is not engaged about the coil I6. In this form of the invention the wires are inserted into the tubular housin I0 and the holding screw 20 is rotated inwards to cause its inner end to bear directly against the coil I6 to hold the wires in position within the tubular housing III.

In Fig. 8 a perspective view of the inner ends of the wires I4 and I5 is illustrated to show the manner in which the inner end of the wire I5 is wound around the inner end of the wire I4 to form the coil I6.

In Fig. 9 a perspective view of a group of wires formed of three separate wires is shown. In

this form of the invention wires [5 and I5 are wound around the inner end of a wire M to form a coil [6,

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. An insulating connector for wires having a tubular housing with a closed end and a group of wires enclosed within a metallic sheath inserted into said housing through its open end, a clamping member on one side of said housing and engageable against said sheath for holding said sheath and wires against outward movement relative to said housing, and means holding said wires against rotation relative to said housing for assisting said clamping member in securely locking said sheath and wires within said ho ing.

2. An insulating connector for wires having a tubular housing with a closed end and a group of wires enclosed within a metalic sheath inserted into said housing through its open end, a

clamping member on one side of said housing and engageable against said sheath for holding said sheath and wires against outward movement relative to said housing, and means holding said wires against rotation relative to said housing for assisting said clamping member in securely locking said sheath and wires within said housing, comprising a loop formed on the inner end of one of said wires and having its top portion disposed within a longitudinal groove formed in said housing.

3. An insulating connector for wires having a tubular housing with a closed end and a group of wires enclosed within a metallic sheath inserted into said housing through its open end, a clamping member on one side of said housing and engageble against said sheath for holding said sheath and wires against outward movement relative to said housing, and means holding said wires against rotation relative to said housing for assisting said clamping member in securely looking said sheath and wires within said housing, comprising a loop formed on the inner end of one of said wires and having its top portion disposed within a longitudinal groove formed in said housing, said groove being extended inwards from the open end of said housing enabling said loop to be properly engaged within said groove from the time said wires are inserted into said housing.

4. An insulating connector for wires having a tubular housing with a closed end and a group of wires enclosed within a metallic sheath inserted into said housing through its open end, aclamping member on one side of said housing and engageable against said sheath for holding said sheath and wires against outward movement relative to said housing, and means holding said wires against rotation relative to said housing for assisting said clamping member in securely locking said sheath and wires within said housing, comprising a loop formed on the inner end of one of said wires and having its top portion disposed within a longitudinal groove formed in said housing, said wire having said loop being extended beyond the inner end of said sheath and other wire.
