An improved mounting component for the device comprises a post having tangs that extend from its side which are deflected to allow the post to be inserted into the board opening and which skive into the sides of the opening to prevent the post from retraction therefrom. An improved positioning arrangement for the device comprises a pair of positioning posts having polygonal cross-sections, each having a maximum cross-sectional dimension in single, mutually orthogonal, directions.
What is claimed is: 1. A device intended to be mounted on a printed circuit board having an opening formed therethrough, comprising:a housing and a plurality of contacts associated therewith; and at least one mounting component for mechanically connecting said device to said printed circuit board, said mounting component including a post connected at one end to said housing, said post having a maximum transverse dimension less than a maximum transverse dimension of said board opening, a slot formed through said post and opening onto substantially opposed side regions of said post, and a clip member situated in said slot, said clip member having terminal ends that protrude beyond the profile of said post, said clip ends constituting tangs, said tangs adapted to deflect upon insertion of said post into said opening in said printed circuit board, and skive into the sides of the opening to prevent removal of the post from said board opening. 2. A device as recited in claim 1 wherein said tangs extend from said post generally towards said housing.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to FIGS. 1-6 of the drawings wherein like reference characters designate identical or corresponding parts throughout the several views, an embodiment of a device in accordance with the present invention, in the form of a jack connector 10 adapted to be coupled to a modular-type plug connector, is constructed of a plurality of conductive contacts 12 (only one shown) and a housing 14 formed of an insulative material, such as plastic, including a first inner housing part 16 and a second outer housing part 18. The connector 10 is similar in several respects to that disclosed in U.S. Pat. No. 4,875,863, the disclosure of which is incorporated herein by reference, which is adapted to be connected to a printed circuit board by contact pins inserted into holes in a printed circuit board.
Referring to FIG. 2 in conjunction with FIGS. 1 and 3-6, the assembly of the connector 10 will now be described. The contacts 12 are initially preformed to the shape illustrated in FIG. 2, i.e., the first and second legs 12c.sub.1 and 12c.sub.2 are bent at right angles to each other. The second leg 12c.sub.2 is formed to include an inclined mid-portion c shaped to conform to the bottom wall 39c of channel 36, and forward and rearward portions a and b shaped to conform to the bottom walls 39a and 39b of channel 36. The mating contact portion 12b is bent at right angles to the second leg 12c.sub.2. Prior to bending the end portion 12a' of the contact corresponding to the pad-engaging portion 12a, the colinear contact portions 12a', 12c.sub.1 of each contact are inserted into a respective bore 32 so that the end portion 12a' of the contact corresponding to the pad-engaging portion 12a projects below the bottom surface 29 of the back portion 26 and so that the second leg 12c.sub.2 of the contact is received in a corresponding guide channel 36 as seen in FIG. 1. The second leg 12c.sub.2 of the contact 12 is supported along its entire length (except where it extends over the open top of the bore 32) by the bottom wall portions 39a, 39b and 39c of guide channel 36. The forward end portions of each contact corresponding to mating contact portion 12b pass over the forward edges 37 of guide channels 36. As discussed above, the dimensions of the guide channels 36 and contacts 12 are such that the exposed upper surfaces of the forward portion a of the second leg 12c.sub.2 of the contact which rests upon the bottom wall 39a of the shallow portion 36a of guide channel 36 is substantially flush with the upper surface 30 of the inner housing part 16. On the other hand, substantial space is provided above the rearward portion b of the second leg 12c.sub.2 which is supported on the bottom wall 39b of the deep portion 36b of guide channel 36. The pad-engaging contact portions 12a are bent with respect to the first legs 12c.sub.1, of the L-shaped contact portion to the shape shown in FIG. 1.
As seen in FIG. 1, the inner surface 50a of the top wall 50 of the outer housing part 18 bears against the top surface 30 of the inner housing part 16. At the same time, the inner surface 50a of top wall 50 of the outer housing part bears against the top surfaces of the forward portions a of the second legs 12c.sub.2 of the contacts 12 from their forward ends up to a point 13 at which the inclined contact portions c begin to extend downwardly away from top wall 50 and along the bottom wall 39c of guide channel 36. The inner surface 50a of the top wall 50 of the outer housing part 18 is spaced from the top surfaces of the rearward portions b of the second legs 12c.sub.2 as best seen in FIG. 1.
