This invention relates to terminal connecters and more particularly to a. terminal connecter for use in connecting battery leads to the terminals of storage batteries.
.5 An important object of the invention is to provide a device of this character which will very firmly clamp the storage battery terminal so as to provide a good electrical connection between the lead and battery and To which is so constructed that tightening of the securing element tends to force the battery terminal down upon the tapered terminal post of the battery so as to increase the contact pressure between the lead and terminal.
A further object of the invention is to provide a device of this character which is so' constructed that in the natural manner of applying the same, the tendency to firm engagement is increased both by the application of'weight and pressure in the operation of the securing element.
' These and other objects we attain by the construction shown in the accompanying 5 drawing, wherein for the purpose of illustration is shown a preferred, embodiment of our invention and wherein Figure 1 is. a plan view showing a terminal connecter constructed in accordance with our invention applied to a battery ter minal; a
Figure 2 is a side elevation thereof;
Figure 3 is a longitudinal sectional view therethrough with the locking member in the locking position; I
Figure 4 1s a plan view partially 'in sec-v tion showing the device in position tore ceive the terminal;
Fi res 5 and 6 are similar sectional views taken through the locking member at the groove showing the position of the lockin member when receiving the terminal and w an locking the same res ctively. V Referring now more particulairly to the 5 drawings, the numeral 10 generally designates a tapered battery terminal and 11 a terminal connecter for connectin to the battery terminal a lead wire 12. T e terminal connecter 11 is in the form of a body 13 v having a bore 14 tapered to conform to the tapering of the terminal post. One end of this body is formed with a socket 15 in which the lead 12 may be inserted and sealed. The body is formed with a second is bore 16 having its axis at approximately right angles to the bore 15, sai ore 16 par- 'of the terminal. tweenthe point 19 and the end 21 of the be maintained at all'times.
tially intersecting the bore 15. 'Rotatable within the bore 16 is a securing element 17 having. at one end an operating head by means of which it may be rotated and pro vided with indicia v18 providing the proper direction of rotation. This securing element 1 is formed with a groove 18 in alignment with the axis of the bore 14, which groove extends partially around the securing element and at a point 19 and is of such depth that when this portion of: the groove is aligned with the bore 14, thebore 14 is unobstructed. From this point, the bore rapidly decreases in depth toward one end 20 7 of the groove and gradually decreases in.
depth toward the opposite end 21 thereof.
The base of the groove is curved in the general direction of the axis of the securing element with a curvature similar to the curvature of the wall of the bore 14 at the point of its intersection by the bore 16.
In the use of the connecter, the same is placed upon the terminal with the securing element so positioned that the point 19 of the groove aligns with the bore 14 When. the terminal is applied, any tendency to rotate the same in the wrongdirection will be frustrated by the engagement of the bot tom wall of the bore between the point 19 and the end 21 of the groove against the side It will be noted that be groove, the curvature at the bottom of the groove is on a true radius eccentric and internally tangential to the securing element, while at that portion of the. groove lying between the point 19 and the en 20, the bottom of the groove is tangential to the eccentric portion; Botation'of the securing element in the proper direction tends to wedge the connecter downwardly -upon the terminal, due to the fact that the rotation of the securing element sets up frictional engages ment between the terminal postand the se-' curing element, and this friction results in a tendency of the securing element to roll upon the face of the'terminal in the direction in which. it is rotated. Since the securing element, as pointed, out, can only be rotated in one direction and when rotated in that direction will tend to move downwardly upon the post, a very. secure wedging1 action will T is tendency is further assisted by the fact that in order to properl rotate the securing eler'nentjit is practice y impossible to engage a wrench like, a body having a bore to receive and fit a terminal and having a second bore at approximately right angles to the first named bore and partially intersecting the same,- a
securing element rotatable and fitting neeaeae Within the last named here, said securing element having a groove extending partially around its circumference, said groove at a point intermediate its ends being of such depth thatwhen aligned with the first named bore said here is uninterrupted to permit the passage of the terminal, the bottom of the groove between said point and one end of the groove being curved and eccentric to the axis or the securing element and internally tangential to the periphery of the body of the securing element, the bottom of said groove between said point and the opposite end of the groove being tangential to said eccentric portion.
In testimony whereof we hereunto afiix our signatures.
