5 Claims. 1
The present invention relates to tube sockets. such as sockets for radio. and like pronged tubes and appliances, and aims generally to improve the construction of existing sockets as well as the contacts therefor.
One of the primary objects of the invention is the provision of a miniature tube socket which is particularly adapted for use with printed circuits.
A further objects of the invention is the provision of a socket which may be of one-piece molded construction and in which the terminals of the contact extend radially outwardly from the socket body.
A still further object of the invention is the provision of a contact terminal in which the end of the terminal is split to form integral tabs adapted to be bent so as to lie on opposite sides of a printed circuit chassis.
These and other objects and advantages of the invention will be apparent. to persons skilled in the art from a consideration of the attached drawings and annexed specification illustrating and describing a preferred embodiment of the invention.
In the drawings:
Fig. 1 is a top plan view of the socket mounted on a printed circuit chassis;
Fig. 2 is a vertical cross-sectional view of the device taken on the line 22 of Fig. 1;
Fig. 3 is a bottom view of the device of Fig. 1
Fig. 4 is a perspective view, partly in section, of the device of Fig. 1;
Fig. 5 is a plan view of the blank from which the contact terminal is formed;
Fig. 6 is a front view of the completed terminal;
, Fig. '7 is a rear View of the completed terminal; and
Fig. 8 is a perspective view of. the terminal.
Referring to the drawings, the socket member may be molded of suitable dielectric material, for example, a phenolic condensation product, and comprises a body portion In having a central aperture H for the reception of a sleeve l2. The sleeve I 2 is preferably of metal and serves the dual function of a magneticv shield and of an attaching means for securing the socket to a supporting part M which may comprise a radio or like printed circuit chassis plate.
The upper surface of the body portion H) is provided with a series of prong-receiving apertures I 5 which are suitably arranged and spaced in matching configuration to the prongs of a tube to be mounted in the socket, and through which the tube prongs or leads may pass freely as will be understood in the art.
The body of the socket I0 is formed with a like series of contact-receiving openings or bores 16, preferably of the same diameter as the apertures l5 and disposed coaxially with and below the apertures 15. Said openings or bores l6 are designed to receive the socket contact members H which are in electrical contact with the tube prongs or leads, and preferably stop somewhat short of the bottom face of the socket body It) to form bottom partitions l8. The partitions I8 are designed to support the main body portions of the contact members and are provided with slits or openings l9 through which the end portions of the contact members are threaded as will be more apparent hereinafter.
Thecontact member I"! is advantageously made from a single strip of suitable conducting metal cut in the form of a blank, as shown in Fig. 5, and then shaped in any suitable manner to form a split tubular body portion or sleeve 20 and terminal contact tabs 2| and 22. The body portion 20 is preferably slotted at its upper end, as at 23, to form a plurality of laterally yielding sections 24, each of the sections 24 being pressed inwardly, as at 25, to provide a constricted throat section 28. It will be apparent that when a tube prong is inserted into the constricted throat portion 26 the laterally yielding sections 24 will be forced apart and will irictionally engage the prong to hold it in place and make electrical contact therewith.
The terminal tabs 2| and. 22 extend outwardly from the lower edge of the body portion 20 in prolongation thereof and are adapted to be threaded through the slits l 9 in the bottom partitions I8 and then bent at right angles on opposite sides of the supporting part M.
The supporting part I4 is exemplified herein as a portion of a radio chassis of the so-called printed circuit type and, as shown more particularly in. Figs. 1 to 3, comprises an insulating panel 27 having. an aperture 28 for alignment with the central aperture I l of the body portion HI and a plurality of apertures 29 conforming in number and arrangement to the prongs of the tube member to be used with the socket, and each adapted to receive one of the terminal tabs of the contact members ll. On both sides 30 and 3| of the panel 21- are applied a plurality of conducting strips 32 and 33. The metal strips 32 and 33 are preferably formed by spraying or painting metal particles on the panel in accordance with the process well known in the art. The strips 32 and 33 are located on the panel in accordance with a predetermined circuit layout, but have their ends 34 and 35 disposed in predetermined positions with relation to the terminal tabs 2| and 22 of the contact members when the socket is secured to the panel.
In assembling the device the contact members are placed in the bores IS with the terminal tabs 2| and 22 thereof threaded through the slits IQ of the bottom partitions IS. The tabs 2! are then bent outwardly at right angles along 1 the bottom of the body portion 10 and radially thereof so as to be in proper position for contacting the conducting strips 32 on the top of the panel 21. The terminal tabs 22 are then threaded through the apertures 29 and bent outwardly radially against the bottom of the panel 21 so that each tab 22 will come into contact with its corresponding conducting strip 33. The socket is then secured to the panel by upsetting the ends of the sleeve 12 in grooves 35. and 31 located respectively in the top of the socket in and in the bottom of the panel 21. The ends of the terminal tabs are then soldered to their respective conducting strips to complete the assembly.
From the above description it will be apparent that the present invention provides a highly effective, inexpensive arrangement of the socket unit, circuits and supporting panel. The invention presents particularly a simple and efiicient method of effecting electrical engagement of the tube-engaging contacts with the electrical circuit of the radio set.
Although I have illustrated and described a preferred embodiment of my invention, I do not intend to be limited to the details thereof as the scope of the invention is best defined in the appended claims.
