RAYMOND T. ROTH, OF NEWYORK, N. Y.
Applicationled September 28, 1923. Serial No.. 665,313.
To all whom t may concer/n.'
Be it known that I, RAYMOND T. ROTH, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Terminal Blocks, of which the following is a specification.
This invention relates to terminal blocks and particularly to terminal blocks adapted to receive a number of conductor terminals for testing or interconnection of the circuits.
The object of the invention is to provide a block of simple durable construction which will insulate the various leads from each other and provide for the designation of the various circuits directly adjacent their points of connection. Y
Other objects of the invention particu larly in the formation of the insulation and conductor strips as` a solid block with integral partitions will appear from the following description taken in connection with the accompanying drawings in which,
Fig. 1 is a plan view of a terminal block embodying the invention.
Fig. 2 is a side view of the same.`
Figs. 3 and 4 are sectional views taken on the lines 3 3 and 4 4 respectively of Fig..
Fig. 5 is .a prospective view showing in detail a terminal conductor strip.
In the embodiment of the invention shown in the drawings the terminalgbloek as a whole comprises a solid body of molded insulating material in which are embedded the terminal'ccnductor strips 6 extending crosswise of the block and separated from each other by the transverse partitions 7 of the molded insulation of/ hard rubber, bakelite or similar material. The-terminal strips 6 (see Fig. 5) of brass or other conducting material are supported in place in the mold into which is poured the insulating material and holding the strips. The mold is shap to give to the insulation a fiat rectangular base portion 8 with enlarged supporting portions 9-,and 10 at each end extendin crosswise vand intermediate partitions 7 'viding the block into a series of transverse channels or ooves 11,
'while a central lon itudinal ri ge 12 extends from end to en of the block. i
There is thus formed a block construction with a .series of recesses or cells on each side, the cell on one side being connectedto faces of the strips around the threaded holesv has the insulation machined away to expose the metal. This tapping and threading is carried through the strip 6 and into the base portion 8 of the insulation (see Fig. 3 Each strip 6 may be formed with a si e groove 16 to give a firm anchorage in the insulation.
The top surface of the longitudinal ridge member 12 is slightly below the top surfaces of the partitions 7 on each side of it so that there is left a central longitudinal groove 17 in which is located a'marking strip 18 of bristol board, Celluloid or the like fastened in place by the screws 19.
The end portions 9 and 10 are provided with openings 19,20, for the fastening means A holding the block in place and these end portions 9, 10 may also serve to carry a cover member when desired.
AThe terminal block of this invention is fastenedin place to receive the terminals of the conductors of the circuits to be tested or interconneceed, tha circuitsdo each conductor stri 6 in esignate y markln' on the strip 18v above the correspon `n circuit. It is obvious that this termina block permits the circuits to be connected 1n shunt or series in any desired manner, each circuit being plainly marked so as to 1nd1- cate at a glancethe relations of the various conductors. Any desired number of ternunal strips 6 may be provided, the block being correspondingly increased instead.
The ends of the conductors are easily fastened in place as shown and the recesses between the partition 7 maintain the terminals safely separate from each other and sunken outof the way of accidental contact with moving parts or wires above.
I claim 1. A terminal block comprising a solid body of molded insulation vhavin end suporting means, a longitudinal rldge memr having means for carrying a marking strip, a series of transverse artitions, an a series of terminal strips em ded in said insulation between said partitions and beneath said ridge member, said terminal strips Ihaving exposed ends in the inner portions of the recesses between said partitions. 2. A terminal block comprising a solid body of molded insulation having end supporting means, a longitudinal ridge member having means for carrying a marklng strip, a series of transverse partitions, and a series of terminal strips embedded in said insulation between said partitions and beneath said ridge member, said terminal strips having exposed ends in the inner portions of the recesses between said partitions, and binding means for fastening the terminals to the exposed ends of said strips.
3. A terminal block comprising a solid body of molded insulation of enerally rectangular shape having upwar lyextending ends serving as supports, a series of transverse partitions extending in the direction of the short dimension of the rectangle, a central-longitudinal marking strip extending across the upper surfaces of said partitions, a series of terminal strips between said partitions and fastened in place between said partitions by the molding of the solid-block of insulation, and binding means for fastening the terminals to the exposed ends of said strips.
