- This invention relates to terminal connecters and more particularly to terminal con.- necters for connecting the lead wires of storage batteries to the terminal posts thereof. An important object of the invention'is to 1 rovide a device of this character which may- 190 very rapidly and easily removed from the terminal post of the battery. 2
A further object of the invention is to provide in a. device of this character an attachment for the terminal post and a lead connecter which has engagement with' the terminal post attachment in such fashion that a proper contact therebetweenis'assured and,
at the same time, a structure produced, the sections of which are readily separable.
Theseand' other objects we attain by'the construction" shown in the vaccompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of our invention and wherein Figure 1 is a plan view of a connecter constructed in accordance with our invention;
Figure 2 is a side elevation thereof;
Figure 3 is a vertical sectional view therethrough; V
Figure 4 is a plan view showing theconnecter in the process of engagement or separation of the sections thereof;
Figure 5 is a side elevation of the malesection. r A
Referring now more particularly to the drawing, the terminal connecter comprises a post engaging section 10 and a lead engag ing section 11. The post engaging section 10 is in'the form of a trunco-conic sleeve 12, the lower end of which is split, as at 13, at a plurality of points seas-to permit expansion of the lower end' of the sleeve. The
upper end of the sleeve is preferably provided with a wrench square 14 and the sleeve has directed therethrough intermediate its ends a pin 16, the ends of which project be- .yond the outer face of the'sleeve.
The-lead engaging section has a socket 17 192a. Serial 1T0. 262,355.
for the reception of the lead .wire 18 and. further embodies an open-topped truncoconic sleeve 19, the u per edge wall of which isformed with cam aces 20 'terminatingadjacent abrupt shoulders 21. The interior of 5 the sleeve in alignment with these shoulders islongitudinally grooved, as indicated at 22. The grooves 22 permit the ends of the'pin 16 which are spaced apart a distance greater than the diameter of the upper end of-the sleeve 19 to be positioned over the upper end a wall for engagement with the cam faces 20 thereof. x
In operation, themale section is forced over the terminal post 23 of the batteryand the sleeve 19 placed in position thereover, With the pins 16 in engagement with the 'cam surfaces 20, it will be obvious that upon J rotation of the lead wire engaging element of the connecter, the sleeve 19 will be forced downwardly, forcing the wings of the sleeve 12 inwardly for firm engagement with. the terminal post, so that a good mechanical as well as electrical connection between the terminal post and the sections of the connecter is provided' The cam faces 20 are separatedby flat sections 22 with which the ends of the, pin 16 .may be engaged, so that the connection; will not 'be displaced by vibration duringuse.
Since the construction, hereinbefore' set forth is capablle of a certain range of change and modificat'on without materially.- departing from the spirit of the invention, we do not limit ourselves to such specific structure ex-. cept as hereinafter claimed.
In a terminal connecter for connecting'the leads and terminal posts of storage batteries and the like, a hollow post engaging section comprising a split conical sleeve and the lead engaging section having a solid conical sleeve,
said sleeves being engageable with one another, the post engaging sleeve having a projectmg pin adjacent its upper end, theupper end of the sleeve of the leadengaging element having a cam surface for coaction with said pin to cause relative longitudinal movement of the sleeves upon relative rotation thereof, the sleeve of the lead engaging section having a groove for the passage of said in the upper end of the split conical sleeve ein closed and provided with a polygonal hea for engagement with the wrench.
In testimony whereof we hereunto afiix our signatures.
