2 Claims. l

short circuits. An object of my invention is to provide a slit connector which is small and easily covered by means of insulating tubing or spaghetti. A further object is to provide such a connector which can be installed directly in the wiring at any desirable point.

Modern airplane construction provides for the assembly of sub-assemblies. For example, wing sections or tail sections are attached to the fuselage, usually in separable fashion, so that when these parts are damaged they may be readily replaced. I have found that, under such circumstances, the electrical wiring between the separable parts should be readily detachable. The use of permanent splices in the wire at these points is, I have found, both inconvenient and wasteful of time. I have additionally found that the separable connectors in the wiring at these points should be such that they will separate at a denite tensile pull, usually about or l2 pounds. Thus, in case of accident, the wires will separate at predetermined joints and damage of wiring and of delicate instruments by pulling or lshock will be avoided.

The primary object of my invention, therefore, is to provide a separable connector which will separate at a predetermined value, in a longitudinally applied tensile pull.

A further object of my invention is to provide a connector to vwhich the wires may be attached with or without the use of solder, as desired.

Another object of my invention is to provide a separable connector4 which can be manufactured by high speed production methods with a minimum of scrap or material waste.

I accomplish these and other objects Aand obtain my new results as will be apparent from the device described in the following specification, particularly pointed out in the claims, and illustrated in the accompanying drawing, in which:

Fig. 1 illustrates a plan view of one part of my separable connector attached to a conductor.

Fig. 2 is a sectional view thereof taken along the line 2-2 of'Fig. 1.

Fig. 3 is an end View of the part.

Fig. 4 is a side elevation of the same.

Fig. 5 illustrates two identical parts assembled together.

Fig. 6 is a longitudinal cross-sectional view of the same.'

Fig. '7 illustrates va modified form of engaging means for holding the two parts together.

Referring more particularly to the drawing, my separable connector consists of two halves or portions I an'd Illa, as illustrated in Fig. 5. which are interlocked together. One of these halvesl. is illustrated in Figs. 1 to 4. It consists of a tubular body II, formed at one end with an enlarged head I2, split as at I3, to receive and by compression to hold the insulation I4 of the conductor I5, and at the other end thereof, two extending fingers I6 and I'I formed by the longitudinal slot'l.

The extending fingers I6 and Il are semi-cylindrical in cross-section, as indicated in Fig. 2, with the finger I6 having a radius of curvature on its outside surface I9 substantially equal to the radius of curvature of the inside surface 20 of finger I1, so that when the two sets of fingers of each half I0 and Illa are interlocked together, they will slidably and tightly accommodate each other as shown in Fig. 6.

The end of fingers I6 and I1 are provided with inwardly bent tabs 2| and 22 at the free ends thereof. An aperture 23 is formed in finger I6 at a point away from the free end for interlocking the two halves, as will be hereinafter explained.

A small indentation 24 may be formed adjacent the neck Il of the half II), so that the inner projection thereof 25 on the surface 20 may be used as a stop for the conductor I5 inserted into the bore 26 of the tubular body I I.

The conductor I5 may be soldered in the bore of the tubular body II or it may be secured therein by the indentation 2l.

In Figs. 5 and 6, where the two identical halves I0 and Illa are shown assembled together, `various parts on Illa, corresponding to I0 are correspondingly numbered with an a placed after each number.

It will be noted that tab. 2Ia of portion Illa is sprung into aperture 23 of portion III, the finger I'la providing a spring effect on the tab so as to maintain it in the aperture under spring pressure. The tabs 22 and 22a of fingers I6 and Ilia ride in the inner surface of fingers I6a and. I6 respectively, and act as a guide to prevent improper assembly of the two halves I0 and Illa.

I havethus provided a. separable connector consisting of two identical parts, each provided with extending fingers so disposed that they will inter lock with the extending ngers of the other part; the inner ngers forming a complete cylinder when interlocked, and the outer ngers providing spring pressure on the inner ngers to keep the latter in close electrical and mechanical contact. The tabs 2l and 2Ia act as catches and the amount of tension required to separate the two parts can be controlled by adjusting this tab.

Various methods of interlocking the two halves may be provided, an `additional example being illustrated in Fig. '7,where the fingers I6 and lBa at the free end thereof may each be provided with a tit 30 and 30a respectively, which snap into apertures 3| and 31a, which may be' positioned in finger I'l opposite the tit, whenv assembled thereto.

I have thus described my invention, but I desire it understood that it is not confined to the particular forms or uses shown and described, the same being merely illustrative, and that the invention may be carried out in other ways Without departing from the spirit of my invention, and, therefore, I claim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by means of which, objects of my invention are attained, and new results accomplished, as it is obvious that the particular embodiments herein shown and described are only some of the many that can be employed to attain these objects and accomplish these results.

What I claim and desire to secure by Letters Patent. is as follows:

`1. A connector for separably splicing two conductors together, consisting of two tubular body sections, each identically provided with a pair of integrally extending fingers, one of said fingers `of each pair having locking means adapted to cooperate with complementary locking means carried by the other body section, for locking the two body sections together, said locking means releasable from the complementary locking means for releasing the two body sections from each other upon the application of a predetermined longitudinally applied tensile force.

2. A connector for separably splicing two conductors together, consisting of two tubular body sections, each provided with a pair of integrally extending fingers, one of said fingers of each pair having locking means adapted to cooperate with complementary locking means carried by the other body section, for locking the two body sections together, the other of said iingers constituting an alignment means to guide the two body sections into proper locking position, said locking means releasable from the complementary locking means for releasing the two body sections from each other upon the application of a predetermined longitudinally applied tensile force.
