VERTICAL MOUNTED CIRCUIT BOARD CONNECTOR This is a division of application Ser. No. 423,941, filed Dec. 12, 1973, now abandoned.

BACKGROUND OF THE INVENTION The connecting or terminating of coaxial .cable to a circuit board requires the terminating of two parallel conductors; i.e., the outer braided shield and the center conductor. Besides providing a reliable termination the connector must maintain the characteristic impedance of the coaxial cable. One such connector is shown in U.S. Pat. No. 3,742,425, the disclosure of which is incorporated herein by reference.

In addition to maintaining the integrity of the cable, it is desirable to provide a connector which is easily manufactured.

It is therefore one object of the present invention to provide an improved cable connector of simple and inexpensive construction.

Other objects and advantages of the present invention will be apparent from the following detailed description of the preferred embodiment thereof.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a circuit board and two vertical mounted circuit board connectors, one exploded over the board and the other assembled therein; and

FIG. 2 is a top plan view of the connector of FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT The circuit board in FIG. 1 is devoid of the etched circuits and components normally seen on such a board for reasons of clarity. The board contains two sets of holes to illustrate the present invention. Each set contains a large center hole 12 partly surrounded by three smaller ground signal holes 14. The center hole 12 contains a conventional spring socket member 16 to receive the center conductor 18 of coaxial cable 20.

In addition to center conductor 18, cable 20 includes a braided shield (not seen) with a dielectric (not seen) between the center conductor and the shield. An electrical terminal 22 is crimped onto the braided shield and the outer insulating jacket 24 of the cable. This terminal 22 is constructed in accordance with the preferred embodiment described in pending U.S. application Ser. No. 325,705 which application is incorporated herein by reference. As the drawing shows, the center conductor 18 extends beyond terminal 22.

The vertical mounted circuit board connector 26 consists of a single item stamped from a coplanar sheet of conductive metal (not shown) and formed into the shape shown. Generally, the connector resembles the figure 8 as seen in the top plan view of FIG. 2. One loop, herein referred to as the first tubular sleeve 28 carries on its base edge 30 three legs 32, 34 and 36. Legs 32 and 34 are identical and project out and away from sleeve 28 at about 120 relative to the third leg 36 which can barely be seen. Legs 3234 consist of a support portion 38 which is generally perpendicular to the longitudinal axis of the connector and a pin 40 which depends from near the free end of the support portion. The third leg 36 consists only of a pin 40 (not seen) which depends downwardly directly from the base of sleeve 28. The pins, when inserted into holes 14 electrically contact a ground conductor strip (not shown) on the underside of board 10.

The second tubular sleeve 42 is split from top to bottom to provide some degree of flexibility to the walls defining the sleeve. This slot 44 enables the second sleeve in cooperation with first sleeve 28 to resiliently engage the shield portion 46 of the terminal 22 with a spring-like action. In addition to imparting spring characteristics to the second sleeve,'the first sleeve provides strength to the connector for mating purposes.

In operation, connector 26 is fastened to the circuit board 10 by soldering pins 40 into holes 14. The cable, its braided shield terminated in the manner seen is pushed into second sleeve 42 so that center conductor 18 is received in the spring socket member 16 in hole 12. The second sleeve receives the shield portion 46 of terminal 22, and in so doing connects the shield to the aforementioned ground conductor strip via legs 32-36 and pins 40.

The foregoing detailed description has been given for cleamess of understanding only, and no unnecessary limitations should be understood therefrom, as some modifications will be ovbious to those skilled in the art.

What is claimed is:

1. An electrical connector apparatus; comprising:

a. a coaxial cable having a braided outer shield, a center conductor and a dielectric between the shield and center conductor;

b. a terminal member having a portion crimped around the braided shield of said cable;

c. a circuit board;

d. a connector having a first tubular sleeve carrying leg members thereon, said leg members attached to the circuit board, and a second tubular sleeve parallel to the first and integral th'erewith, said second sleeve resiliently engaging said portion of the terminal engaging the braided shield and the center conductor of the cable extending into the circuit board.

2. A connection comprising: i

a. a printed circuit board having a first aperture and at least three second apertures spaced from and surrounding the first aperture on at least three sides;

b. a connector, stamped and formed from a single coplanar sheet of conductive material, having a first sleeve with one pin depending directly downwardly therefrom and two legs projecting radially outwardly with each leg having apin depending downwardly therefrom, said three pins being positioned in the three second apertures in the printed circuit board, said connector further, having a second sleeve positioned to one side of the first sleeve, the walls of the first sleeve providing spring members for lateral movement by the walls of the second sleeve; and i a coaxial cable having a terminal crimped onto its braided shield positioned in said second sleeve with the walls thereof encompassing the terminal and the center conductor of the cable extending beyond the terminal and positioned in the first aperture in the printed circuit board.
