Application March 20, 1946, Serial No. 655,715
1 Claim. 1
This invention relates generally to electrical connectors and more particularly to panel mounting connector of the type used in microphones, amplifiers, sound equipment and the like.
Heretofore in connectors of this character contact has been made between the cable or con ductor and the coupling by means of an eyelet through which the cable is pushed and then soldered, the solder joint being the only contact existing. Due to the soft material of the solder, continuous pressure caused by tightening the coupling nut will loosen and flatten the joint thus resulting in noise. Also the flux, which is used in soldering the cable to the eyelet, causes considerable electrical leakage across the insulator. Furthermore, in some of these connectors when the parts wear down, the connector turns in its supporting panel with consequent displacement of the parts.
It is a primary object of the present invention to overcome the foregoing defects.
Another object is to eliminate leakage and noise.
A special object is to provide means for preventing the connector turning in its mounting.
Another object is to provide a connector of this kind that is simple in construction and economical to manufacture.
Other objects and advantages of the invention will appear from the description thereof to follow taken in connection with the accompanying drawing in which Fig. 1 is a longitudinal sectional view of the improved connector shown mounted in a panel and in operative position in the socket portion of an electrical connector, said latter electrical connector being shown in dot-dash lines and partly broken away.
Fig. 2 is a side view of the improved connector with the panel omitted.
Fig. 3 is a sectional View taken on the plane of the line 33 of Fig. 1.
Fig. 4 is a sectional view taken on the plane of the line 44 of Fig. 1.
Fig. 5 is an end view looking in the direction of the arrows 5-5 of Fig. 1.
The improved panel mounting connector comprises a tubular body 5 provided with external screw threads 6. The body is formed at one end with a reduced portion 1 providing a shoulder 8 and having an externally screw threaded portion 9.
The large end of the body is closed by an insulating disc [0 which is seated against a shoulder II at said end and secured therein by peening over the outer edge of the body as indicated at l 2. Supported by this disc and disposed axially of the body portion is a contact member comprising a solid elongated pin l3 preferably silverplated and extending inwardly through the tubular body and through another insulating disc l4, closing the end of the screw threaded portion 9, to the exterior of said disc l4. Disc I4 is secured in position by peening over the edge of the body. The exteriorly protruding portion of the pin is formed with an integral semi-tubular soldering lug l5, and the opposite end of the pin is formed with a head or button I 6.
In use, the connector body 5 is screwed into the socket member of an electrical connector ll. such as the coupling nut l8 of the electrical connector disclosed in my copending application, Serial Number 655,714 filed March 20, 1946, until the head portion I6 of the contact pin I3 frictionally engages a contact I!) in said electrical connector. The connector body is mounted in a panel or chassis 20 and the reduced portion 1 thereof is formed with a flat milled section 2| as seen in Figs. 2, 4 and 5, which passes through an opening 22 in said panel. A fibre washer 23 is interposed between the panel and the shoulder 8 and its inner periphery is provided with a flat edge adapted to coact with the flat milled section 2| of the body to prevent turning of said washer. The washer is formed with oppositely disposed peripheral lugs 24 adapted to interlock with notches 25 in the opening in the panel whereby the body is prevented from turning. Another washer 26 is positioned on the other side of the panel and the assembly is fastened to the panel by a nut 21 leaving the solderin lug l5 exposed for connection to a conductor (not shown).
Changes in details might be resorted to without departing from the principle of the invention and I desire to be limited only by the state of the prior art and the appended claim.
I claim:
The combination with a panel having an opening therein with notches in the inner periphery thereof, of an electrical connector of the character described comprising a tubular body portion havin an externall screw threaded section at one end thereof, the opposite end of the body portion having a reduced portion with an externally screw threaded section, an insulating disc closin each end of said body portion, an elongated solid contact pin extending axially through said body portion and supported by said discs and having one end protruding externally of said reduced portion and an integral semi-tubular lug on said pro- 3 truding end for connection to a conductor, a portion of the periphery of said reduced portion having a fiat surface, extending through the opening in the panel, a Washer member on said flat surface between the body portion and the panel, said 5 REFERENCES CITED The following references are of record in the file of this patent:
