Description
VIDEO CONNECTOR FOR PRINTED CIRCUIT BOARDS / c 1 1 r', 5 t, I' -, A_ -g L
The present invention relates to a receptacle for a video C onnector and, more particularly, to a triple coaxial receptacle for preventing the accidental mating of different color cables.
Conventional connectors (i.e. terminators) for electronic video equipment are typically of the male or female type having a central electrical contact insulated within an annular ground socket or stud. The conventional connectors are of the SMPTE (Society of Motion Pictures and Television Engineers) type for receiving coaxial cables. The connectors are used to provide a grounded closure for terminals on electronics, telecommunications, or video signal processing equipment and the like in order to maintain a specified impedance relationship for circuitry associated with the terminal, and to prevent shorting or spbrious. input into the terminal from external causes. The terminals are usually colorcoded and installed on a printed circuit board (i.e. "patch panel") for electronic equipment or on the ends of similarly colored coaxial cables and the like.
The SMPTE connectors are typically arranged individually about a printed circuit board. Different monitors are patched into the switchboard for receiving video signals. In the assembly of the printed circuit board, the color-coded receptacles are separately mated one at a time with the Z. - a respective color cables to form a continuous connection between the same color video signals. However, while this form of separate connection is widely used, accidental mating of different color cable s often occurs, causing distorted color video signals.
The present invention provides for a novel printed circuit board connector in the form of a triple coaxial receptacle. In this manner, three color connectors can be mated simultaneouslyyet individually so that the different color cables do not get mixed up.
The connector comprises a molded body main portion having three conductive annular contacts wherein each contact has a central electrical contact element insulated from the annular contact. The rear portion of each contact includes one central electrical lead, for electrical contact with a contact element, and four prongs for securing the main portion in electrical contact with the printed circuit board. The front side of the main portion also has two sockets of a pin/socket assembly for securing the central electrical contact element with the lead of a coaxial cable.
Accordingly, it is an object of the present invention to provide an electrical video connector assembly for a printed circuit board which prevents the accidental mismating of different color cables.
It is a further object of the invention to provide an electrical connector which is highly useful in vdeo monitors for the connection of cables used to transmit video signals.
W tc -i 3 1 7 It is another object of the invention to provide an electrical video connector which is extremely convenient for the simultaneous connection of multiple coaxial cables and color connectors.
It is a still further object of the invention to provide an electrical video connector that satisfies the foregoing objects while being economical to manufacture.
Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims.
In the drawings, wherein similar reference characters denote similar elements throughout the several views; Figure 1A is a front view of the electrical connector of the present Invention; Figure 1B is a side view of the electrical connector taken along lines 1B- 1B of Figure 1A; Figure 2A is a top view of an alternative embodiment of the electrical connector; Figure 2B is a rear view along lines 2B-2B of Figure 2A; k Figure 3A is a front view of the alternative embodiment of the electrical connector along lines 3A-3A of Figure 2A; and Figure 3B is a side view along lines 3B-3B of Figure 3A.
-Referring to Figures IA and IB, there is shown an electrical video connector designed in accordance with the present invention. More particularly, in the design of connector 1, central contact element 2 is surrounded by insulating material 3 and an outer cylindrical terminal 4. Three of the terminals are constructed as a unitary piece on the front side of molded body 5. At oppositely disposed corners of molded body 5, socket assemblies 6 are fixedly attached thereto to receive the mating pins (not shown) of a similarly constructed coaxial cable assembly. Large lead guide pin 7 and small lead guide pin 8 mate with the corresponding receiving sockets (not shown) of the coaxial cable assembly to ensure proper alignment of the electrical components.
As seen from Figure IB, the rear side of each of the terminals 4 of connector 1 have central electrical lead pin 9 and prongs 10 which insert into a printed circuit board (not shown) for mounting and electrical contact. Each of the terminals 4 corresponds to a red, green or blue video signal, respectively. When the three terminals are unitary with molded body 5, as in the present invention, th simultaneous connection of the red, green and blue coaxial cables provides for an easy and convenient way to prevent accidental mating of different color cables. Accordingly, the correct video signals will be dispatched into the appropriate color monitors without i i i t -1 any mix-up. Therefore, the present invention would have widespread and immediate use within the broadcast industry.
Figures 2A to 3B show an alternative embodiment of the present invention wherein the rear side termination of connector I is formed at a right angle for mounting on a printed circuit board. Figure 2A shows rear portion 12 of molded body 5 formed so that central electrical lead 11 is bent at a right angle. Lead 11 and prongs 10 are then inserted onto a printed circuit board for mounting and electrical contact.
Y e t As Figure 2B shows, cylindrical terminal 4 extends through molded body 5 to rear portion 12. Prongs 10 are formed around the inner circumference of terminal 4 and are removable therefrom to allow replacement with some other type of circuit board attachment element such as, for example, solder cups. As is evident, various terminations can be obtained by changing the prong 10 inserts. Any other type of element for attaching the connector can also be used by this substitution design of the present invention. Additionally, the right angle assemblies can alo-be modified in the foregoing manner to provide for convenience and ease of maneuverability in designs where accessibility may be a problem.
The above described embodiments are merely illustrative and not intended to limit the scope o:E the invention. Various omissions, substitutions, and modifications in the form and details of the device may be made by those skilled in the art without departing from the scope and spirit thereof. All such modifications and variations are intended to be encompassed within the invention as defined in the following claims.
