Telephone Laboratories,
Incorporated, New
York, N. Y., a corporation of New York Application July 25, 1931, Serial No. 553,107 6 Claims. (01. 173-328) This invention relates to mountings for electrical devices and more particularly to such mountings for devices employing currents of large mag- One object of this invention is to prevent deleterious heating of the contacts in mountings for electrical devices employing currents of large magnitude.
A further object of this invention' is to simplify the structure, to expedite the manufacture, and to reduce the cost of mountings for electrical devices.
In accordance with this invention a mounting, such as a socket for high current discharge devices, comprises a base plate, a top plate and an intermediate plate secured in spaced parallel relationship. The top plate and the intermediate plate are provided with complementary aligned apertures for receiving terminal prongs on the device. A plurality of conducting members are mounted on the intermediate plate and each comprises an expansible cylindrical contact portion extending through one of the apertures in the intermediate plate and adjacent the corresponding aperture in the top plate, an outwardly extending terminal portion having an integral anchor or lug for attachment to the intermediate plate, and an intermediate flexible portion integral with .the terminal and contact portions for compensating for variations inthe spacing of Each of the contact slits extending from opposite ends. thereof 1 and alternately arranged to increase the resiliency of the contact thereby insuring positive engagement with the terminal prongs. An independent electrical terminal is mounted on the top plate for connection to aterminal on the device remote from the terminal prongs thereof.
The spacing of the plates allows adequate cooling and insures rapid dissipation of the heat generated in the contacts and thereby prevents deleterious heating of the-contacts and the plates. The flexible portions and the slits in the contacts insure positive and eilicient engagement of the contacts with the associated terminal prongs of the electrical device.

elevat on o! a socket for cted in accordwlng the complete Fig. 2is a plan view of the socket shown in Fig.
1 with a portion of the top plate broken away to show the arrangement of a terminal and contact member;
Fig. 3 is an enlarged perspective view of a contact and terminal 'memberin accordance with a feature .of'this invention; and
Fig.4 is a, cross-sectionalview along line 4-4 of Fig- 2.
Referring now tothe drawing, a mounting for 10 electrical devices, such as a socket for an electric discharge device,comprises in accordance parallel relation to the base or support by tubular 20 spacers or sleeves 15.
A top member which-may consist of two flat plates 16 and 17 of insulating material, is supported in superimposed relation parallel to the intermediate plate upon tubular spacers or 25 sleeves 18. A plurality of eyelets 19 extend through the plates of the top member, theplate 14, plates 10, 11 and 12 of the base and spacers 15 and 18, and secure these elements together to form a compact, rigid structure.
The plate 16 is provided with a centrally positioned circular opening 20 which forms a recess with plate 17 in which are located openings 21 in the plate 1'7. The plate 14 is provided with apertures in alignment with the openings 21 in the plate 17.
Arrangedfin the'apertures of the intermediate plate 14 are unitary conducting members, each comprising a cylindrical contactportion 22 for receiving a prong of an electrical device, such as a discharge device, an outwardly extending ter-- or lugs 25 integral with the terminal portion 2a -wl'iichextend downwardly through slits in the intermediate plate 14. Displacement ofthe conducting members is prevented by the top member and the base. The terminal portion 23 may beprovided with a slot 26 for facilitating attachment of a wire connection to the terminal. The
cylindrical contact portion 22 of each strip extends through one 01' the apertures in the plate 14 and is provided with a flared rim or lip 2'1 positioned adjacent one of the openings 21 in the plate 17. The contact portion 22 is further provided with sets of slits 28, 29 extending from opposite ends 01' the portion 22 and alternately arranged.
This socket construction allows the free circulation of air or other gaseous cooling medium between the several plates and around the contact portions 22 so that dissipation of heat generated in the conducting members during operation of the device mounted in the socket is insured, deleterious heating 01' the contacts is prevented and the handling of high currents is expedited. The slits 28, 29 in the contact portions turing tolerances.
simple construction and may be manufactured expeditiously in large quantities and at low cost.
22 insure a positive engagement between the contact portions 22 and the terminal prongs of the electric device inserted therein and also insure a low contact resistance between the contact portions and the terminal prongs. The flexible portion 24 allows displacement of the contact portions 22 to compensate for variations in the spacing of the terminal prongs on the base of the electrical device occasioned by manufac- The! entire mounting is of An independent terminal 30 may be mounted on the plate 17. The terminal 30 is preferably mounted on the top member to provide high insulation between the terminal 30 and the terminal portions-23 of the conducting members. In high current rectifier discharge devices, for, example, the anode terminal is usually sealed in the top of the enclosing vessel. Connection thereto may be established by a flexible wire 31 attached to the terminal 30 and a clip 32 adapted to engage the anode terminal. The cathode terminal prongs of such a device are usually mounted on an insulating base secured to the enclosing vessel and may be inserted into the cylindrical contacts 22 through the apertures 21.
While only two conducting members are shown in the drawing, it is, of course, understood that three or more conducting members may be arranged in spaced relation in the mounting. For instance, in high power amplifying devices the terminal prongs on the base thereof are connected to the cathode, grid and anode and, therefore, the mounting of this invention can easily be designed to accommodate the terminal prongs of such a device. a
