TERMINAL FOR ELECTRIC CONDUCTORS.

Application led April 29, 1926. Serial No. 105,385.y

This invention relates to terminals for electrical conductors and particularly to the type which serves as a connector for two r more conductors.

An object of the invention is to provide an improved terminal which is simple in operation, of few parts, and economical to construct.

In accordance with one embodiment of the invention, herein shown and described,

.there is provided a clamping means comprising a. stationary member or frame. and a movable member, said members having oppositely disposed clamping surfaces. The movable member is connected with the stationary memb-er by means of a shaft and the clamping surfaces are normally vheld in the clamped position by a spring. A push rod is provided to transmit applied pressures to the lower end of the movable member which causes the latter to move about the shaft and thereby separate the two clamping surfaces. The relative distances through which the lower and upper portions of the movable member move can be controlled by correctly proportioning the distances between the pivoting point and the end portions of the movablemember.

The invention may be more clearly under- :i: stoodvby referring to the drawing in which Fig. 1 is a perspective view of the device, Fig. 2 is a front view with a portion of the frame removed, and VF ig. 3 is a side view.

In the drawing the metallic stationary member or frame 5 is secured to the panel 6 by means of machine screws 7-7. The movable member 8, preferably of conducting material, is mounted on a shaft 9 which passes through the projections 10 of the frame 5.k The wire spring 11 consists of two .spiral portions 12 positioned about the shaft 9 and the extended

portions

13 and 14 which bear respectively against the projection 15 of th-e frame 5 and against the top of the movable member 8. In assembling, the spring 11 is inserted under tension so as to exert al pressure against the movable member 8. The rod 16,'which can be depressed by applying pressure to the button 17, passes through holes in the insulating panel 6, the top of the frame 5 and the projecting portion 15 and bears against therlower portion of the movable member 8. A pin 18 is ypassed through a hole in the push rod 16 so as to prevent the push rod from falling out when the device is inverted. The rectangular shaped opening 19 through panel 6 and the stationary 4member is adapted to receiveV one or more conductors l2O, which are to be connected' together or to a conductor which' is soldered or otherwise connected to lug 22, secured to the frame 5.

VThe clamping surfaces

23 and 24 of the fra-me 5 and the movable member 8, respectively, are lmurled or otherwise roughened so as to form a gripping surface.

In operation, when the button 17 is depressed the rod 16 transmits a pressure to the lower portion of the movable member 8, which is thereby caused to rotate about the shaft 9 and sepa-rate the gripping surface 24 of the movable member 8 from the opposite-ly disposed gripping surface 28 of the frame 5. The conductors 20, which are to be connected, are then inserted through the opening 19 after which the button is released, thereby permitting the spring 13 to exert a pressure against the upper portion of the movable member 8. The conductors are thus firmly gripped between the

surfaces

23 and 24 and are thereby elec'- trically connected through the metallic frame to the lug 22.

What is claimed is:

1. In combination with an apparatus mounting panel, a terminal for electric conductors, said terminal comprising a stationary conducting member and a movable member, said members having oppositely disposed clamping surfaces, means foiupivotally mounting said movable member upon said stationary member, a spring for normally holding said clamping surfaces in engagement, means for mounting said terminal upon the back of said panel with the clamping surfaces substantially perpendicular to the face of said panel and means passing through an opening in said panel and operable from the front thereof to separate said clamping surfaces. i

2. A terminal for electric conductors, comprising a pair of conducting members hav-V ing oppositely disposed clamping surfaces, a spring for normally holding said clamping surfaces in engagement and means loosely impinging against one of said members to separate said clamping surfaces against the tension of said spring.

3. A terminal for electric conductors comprising a substantially U-shaped stationary IUD meix'iber oli sheet metall having o serrated portion nenr one end und laterally projecting portions near the other end, :i movable L shaped member of sheet metal having :L serriitel portion neer one emi und laterally projeetii'ig portions" between the enfle thereof, e simil'. passing through :ill ot said laterally projecting portions to pivotolly moniitseid L-ssheped member upon seid U-slm'ped member, :mid serrated portionss cooperating to ilforiil :i demping means, und :1 spring to loree the clamping surfaces o'l' suii'l L-Shzipecl mem ber towznrl that ot' smid Ushz1pecl member.
