'4 Claims. (Cl. 173-328) This invention relates generally to electrical connection means and more particularly has to do with what is known in the trade as a line connector for providing a detachable electrical connection between two or more lines or circuits.
More specifically, the invention is directed to a connector consisting of two generally tubular members, one of which is in the form of a sleeve of insulating materialand the other is in the form of a metallic insert or electrical connection means disposed within the sleeve.
One particular object of the invention is to provide improved means for locking the insert within the sleeve.
Another object of the invention is to provide a connector which may be easily and quicklyassembled and manufactured economically on a commercial scale.
Other objects and advantages of the invention willbe apparent. after reading the description hereinafter set forth in conjunction with the drawing annexed hereto.
In the drawing:
Figure l is a longitudinal sectional view of the first embodiment of the connector;
Figure 2 is an end view of the connector shown in Figure 1;
Figure 3 is an end view of the insert forming a part of the invention;
Figure 4 is a side view of the insert shown in Figure 3;
Figure 5 is a surface development of the insert used in conjunction with the connector illustrated in-Figure 1; and
Figure 6 is a second embodiment of the invention.
Referring to the first embodiment of the invention illustrated in Figures 1 through 5 of the drawing, numeral i represents a tubular sleeve of insulating material, preferably more or less rigid in character, and 2 represents a generally tubular metallic insert disposed within the sleeve.
The sleeve I may be constructed as desired, but is preferably provided with aligned substantially cylindrical recesses 3 and 4, separated by a rib or partition 5. This partition is preferably made integral with the sleeve and is provided with an annular aperture or hole 6 of a diameter somewhat less than the diameters of the recesses 3 and 4 and forms a passage between the latter. The opposite faces of this partition or bases of the recesses are preferably arranged in parallel relation and transverse to the longitudinal axis of the sleeve whereby to provide a pair of abutments or shoulders I and 8.
As stated above, one important object of this invention is to provide improved means for looking the insert 2 within the sleeve and this is accomplished by providing the insert with a plurality of resilient or yieldable independently operable holding portions such as 9 and ,III which straddle the partition 5 and more or less engage the abutments I and 8.
g The insert may be constructed as desired and, as illustrated in Figure 5', is preferably constructed from a square or rectangular Piece of rather thin sheet metal resilient stock. Each longitudinally extending marginal edge of the insert is preferably provided with a pair of holding portions, projections, or tongues 9 and I0; and are preferably formed by the relief slots II and the interruption or centrally disposed opening l2, It will be evident that the pairs of tongues 9 and I0 are oppositely disposed and project in a direction transverse with respect to the longitudinal axis of the insert, and that the tongues 9 are preferably arranged on oneside of the center of the insert and the locking portions ill on the other side of the center in order to provide a wellbalanced construction. When the development in Figure 5 is fashioned as illustrated in Figures 3 and 4 the extremities l3 and I4 of the insert provide means to which conductors may be secured and such means is preferably in the form of split tubular terminal receptacles adapted to receive plug conductors of the character illustrated in Figure 1. A detent such as l5 may be provided in each receptacle for cooperation with the groove in the plug conductor whereby to assist in holding the conductors with respect to the insert. When the insert is fashioned or formed into the desired shape certain of the holding or tongue portions, such as I 0, are preferably left extended so that they project outwardly or laterally with respect to the remainder of the insert.
To assemble the insert with respect to the sleeve I, the extremity or receptacle I 3 of the insert is merely inserted into the aperture 6 of the partition 5 via the recess 4 until the portions I 0 engage the shoulder or abutment 8, whereupon a suitable tool may be inserted into the other recess 3 in a manner wherebyto forcibly-press the tongues 9 outwardly with respect to the remainder of the insert to an extent or distance, substantially corresponding to that of the tongue portions It), to more or less engage the abutment 1 and thus positively lock the insert in place. Due to the fact that the locking portions 9 and III are spaced apart longitudinally and the fact that the partition 5 provides a bearing for part of the insert, the plug conductor receptacles "and I4 or means to which the conductors may be secured, are arranged in concentric spaced apart relation with respect to the recesses 3 and 4, respectively. More specifically, in this respect, it is to be noted that the locking tongues 9 and I project outwardly to an extent substantially equivalent to the radial extent of the partition 5 so that the longitudinal axes of the insert and sleeve, as viewed in Figure 1, coincide.
Referring to the second embodiment of the invention illustrated in Figure 6 of the drawing, the connector includes an insulator 20 and an insert 2|. In this embodiment the insulator or sleeve is provided with a lug 22 which is chordal in character and not entirely annular as the partition 5 above referred to. The insert 2| is provided with a plurality of holding portions 23 and 24 which correspond to the tongue portions 9 and [0, above referred to, and these holding portions receive the lug 22 to lock the insert in place. By this arrangement that portion or portions of the insert opposite the portions 23 and 24 will engage a wall of the aperture 25 formed in the insulator 20. More specifically, the insert is engaged substantially throughout its entire length by the wall defining the aperture 25 of the insulator, or to put it another way, the yieldable holding portions 23 and 24 resiliently support the insert and press the insert against a portion of the wall of the aperture, and at the same time maintain another portion or portions of the insert in spaced apart relation to another portion of the aperture wall.
A pair of resilient or yieldable tongue portions or projections 26 more or less corresponding to the yieldable holding portions 23 and 24 preferably provided adjacent each extremity of the insert and acting to resiliently support the insert at its extremities.
In view of the foregoing, it will be evident that a number of improved means have been provided whereby a conducting member or insert may be secured or locked in place and resiliently supported within a sleeve of insulating material.
Having thus described my invention, it is obvious that various modifications may be made in the same without departing from the spirit of the invention; and, therefore, I do not wish to be understood as limiting myself to the exact forms, constructions, arrangements, and combinations of parts herein shown and described. In this connection, it is to be distinctly understood that insofar as this invention is concerned, it is immaterial as to the cross-sectional character of the inserts and sleeves; in other words, they may be triangular or square in cross-section, and the like.
I claim:
1. Electrical connection means including, a tubular insulator having an abutment therein, a conducting member insertable into either end of said insulator disposed in said insulator having means to which a conductor may be secured, spaced apart resilient means provided on said member receiving said abutment for locking said member within the insulator, and resilient means provided adjacent the extremities of the member ,and adapted to engage the inner wall of said insulator for resiliently supporting said ex-' ment means therein, an insert disposed in said opening, said insert being provided with means to which a conductor may be secured, longitudinally spaced apart resilient projections provided on said insert adapted to engage a wall of said opening whereby to resiliently support at least one extremity of, the insert, and other resilient projections provided on said insert cooperating with said abutment means for locking the insert in place and engaging the wall of said opening for resiliently supporting the central portion of said insert.
4. A circuit continuing member adapted for connection with an insulator, said member being in the form of a. generally cylindrical split tube, the extremities of which are adapted to have substantially cylindrical conductors detachably connected thereto, said member having resilient portions intermediate said extremities whereby the portions may be employed to assist in securing the member with respect to said insulator, and said member also having resilient tongues adjacent one extremity which may be employed to resiliently support at least a part of said member with respect to said insulator.
