8 Claims. 1

My invention relates to electrical connectors of the quick detachable type which are positively locked together when assembled.

In many forms of electrical wiring it is desirable to provide quick detachable or separable connectors for convenience in servicing, testing or the replacement of portions of such wiring. This is particularly necessary. as an example, in military aircraft, where damaged wire or cable must be replaced quickly, so that the airplane may become serviceable as soon as possible. In such aircraft, it is also desirable that the separable connections do not pull apart or separate accidentally as a result of personnel pulling on the wires while using them as handhoids or supports when walking or in the performance of their duties.

Since weight must be saved in military aircraft to the greatest extent possible, and since many separable connectors are used in each airplane, it is very desirable that the separable connectors require no extra wire or cable or "slack in order to permit them to be opened or closed. My separable connector permits the wires to be actually pulled taut in making the connection.

One object of my invention is to provide such a connector which can be assembled without requiring any slack in the wires or cable which it joins.

Another object of my invention is to provide a separable connector which cannot be pulled apart or otherwise accidentally separated.

Still another object of my invention is to provide a separable connector which can be readily taken apart manually or with the assistance of commonly available tools such as a screwdriver.

A further object of my invention is to provide a separable connector which is easy to manuiacture by mass production methods and is low in cost.

I accomplish these and other objects and 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. i is a perspective view of a separable connector half with open gripper means.

Fig. 2 is a. perspective view of my connector with one gripping means in open position.

Fig. 3 is a side elevation of the same with both gripping means in closed position.

Fig. 4 is a bottom. view of the same.

Fig. 5 is a sectional view through 5-5 of Fig. 3.

Fig. 6 is a view of a flat terminal portion.

Fig. 'l is a perspective view of another pair of flat terminal portions.

My separable connector may consist of two identical halves ill and iila which are assembled to each other in actual use. as is shown in Fig. 2. In the drawings elements of connector half Illa will be similarly designated as half i0.

Each half, as shown in Fig. 1 consists of a barrel, or socket portion ii into which a wire or cable I! is inserted and attached by either the indentation III or by other well known methods. The extending flat tongue I may be made by flattening a tube the end of which forms the socket ii, and trimming the edges. A recess i5 is provided adjacent the socket. At the other end of the tongue a u-spring clasp l6, having legs l1 and I8 spaced apart sufficiently to spring clasp the two tongue sections it and Ila, is plvotally mounted by means of rivet i9 as shown in Fig. 2. The rivet i! has a dish-shaped head 20, on the same side of the tongue H, as contains the recess i5. It has a diameter sufiicient to allow it to be positioned in the recess i5a of the interlocking half iila.

The leg i8 of the clasp has an arm II which extends eccentrically of the clasp, so that when the clasp is in the closed position. the U-shaped portion will extend transversely across the tongue sections, supported by the pivotally mounted arm. At the end of the arm. a stop tab 22 is formed to prevent the clasp from opening more than from the closed position, at which open position it will engage the edge of the tongue. This facilitates assembly and prevents the clasp from being improperly closed.

Because of the spring clasping pressure sometimes required. screwdriver slots 23 and 24 may be provided in the legs i1 and i8 of the clasp, to assist in the opening and closing of the clasps. Thus when it is diflicult to open and close the clasps by hand the blade of a screwdriver may be inserted in one of the slots, and a turning couple exerted in the proper direction, which will cause the clasp to rotate easily.

To assemble the two halves of the connection together. it is first necessary to place the springs in the open position as shown in Fig. 1. The tongues i0 and Illa of the two halves are then placed, one over the other, with the dish shaped head 20a resting in the recess I5, and dish shaped head 20 resting in recess iia. The two ciasps i6 and iBa are closed by rotating them 90, as is illustrated by clasp iii in Fig. 2.

The U-shaped clasps then grip the two tongues together with strong spring pressure. providing a good "wiping" type oi electric contact. At the same time, the rivet heads, locked in the shallow recesses. prevent separation of the two halves as a result of longitudinal or transverse stresses.
