Abstract

A connector component is provided with contacts having an elongate cross-section main body and a reduced terminal section extending from one side of the main body. The contacts are disposed parallel to and aligned with each other and are oriented such that the terminal sections extend from opposite sides of the main bodies. In this manner, one of the terminal sections may be bent perpendicularly to its long dimension toward the other of the contacts without passing over the point where the other of the terminal sections extends from the other of the contacts.

Description

Connector Component Contact System
Field of the Invention
The present invention relates generally to electrical interconnect systems and particularly to electrical connector components of such interconnect systems .
Background of the Invention
Interconnect systems refers generally to the connection of electrical or electronic devices and includes all the components necessary for connection, such as cabling, connectors for attaching cable to circuit boards or another cable, or connectors for directly attaching one component such as a circuit board to another. The present invention concerns itself particularly with projection type connector components wherein a conductive pin, or more typically, an array of a number of conductive pins, are mated with a number of similarly arrayed conductive sockets.
Such connector components may be mated and separated a large number of times and are usually employed to connect electrical cable to a device or another cable or to connect electronic devices, such as circuit boards, directly to one another. It is desirable that such connector components be as small as possible, both to conserve space and for performance reasons . The smaller the connector components the shorter the conductive path within the connector, which generally translates into the ability to transmit electrical signals at higher speeds than a connector having a larger size and longer conductive paths. Small size, however, creates its own problems in terms of the strength of the very small components, the ability to assemble such components and the fact that small, thin components will wear to a point of failure very quickly if care is not taken in their design.
One particular connector design of which applicant is aware achieves small size and high density in a projection-type connector by providing a male connector component having a square projection of electrically insulative material surrounded by four metal contacts in electrical isolation from one another. The four male contacts mate with four cantilever beam contacts arranged to form a square female socket. Each of the male contacts engages one of the beam female contacts to complete an electrical circuit, and thus four connections are achieved at a single projection.
A problem that has been recognized with the connector just described is that the high density of the contacts creates problems in arranging the terminal ends of the contacts such that one contact does not touch or interfere with another contact. This is particularly true when the terminal ends of the contacts must be bent at, for example, right angles to make connection to another device.
Summary of the Invention
The present invention prevents interference between the terminal portions of contacts by providing two electrically conductive contacts, each having a main body with a length and an elongate cross-section, a reduced area terminal section extending parallel to the length of the main body and from one end of the elongate cross-section of the main body, and a substrate mounting the two contacts, wherein the contacts are disposed with the long dimensions of the elongate cross-sections parallel to each other and such that their edges are aligned, the terminal sections extending from opposite ends of the contacts so that the terminal sections may be bent perpendicularly with respect to the long dimension of the elongate cross-section from one contact toward the other' without extending over the point of attachment of the other of the terminal sections to the main body of the other of the contacts. There are preferably two sets of two contacts arranged so that each contact is centered on one side of a square pattern, and each contact main body is preferably rectangular in cross-section with the terminal section being square in cross-section.

Figure 1 illustrates a male connector component, generally indicated as 10, which is designed to mate with a female connector component, generally indicated as 12 in Figure 2. The male connector component 10 includes a body 14 which may be formed by any process such as molding or machining, but which is preferably molded of an electrically insulating material forming a substrate 16 and a wall 18 surrounding a number of projection type contact assemblies 20. The contact assemblies include a central, insulative buttress 22 of electrically insulative material surrounded by four electrically conductive contacts 24. The buttresses 22 are preferably molded as an integral part of the component body 14, but may be constructed separately, either by molding or machining or similar process, and later attached to the body 14 by any suitable process such as adhesive joining or welding. The material used to form the connector component body 14 and the buttresses 22 may be any conventionally used electrically insulative polymeric material, but preferably is a liquid crystal polymer, and more particularly is a liquid crystal polymer manufactured by Hoescht Celanese and identified as Vectra. The electrically conductive contacts 24 may be formed of beryllium copper, phosphor bronze, brass, tin, gold, palladium, any suitable alloy of the foregoing, or any other suitable conductive material. A suitable material is one which exhibits sufficient conductivity to usefully transmit electrical signals and wear and strength characteristics which allow it to survive a desired number of assemblies to and separations from the female connector component 12. Preferred materials are beryllium copper, phosphor bronze, brass or another copper alloy plated with tin, gold, palladium or a combination of two or more of the plating materials. As is best seen in Figures 1 and 3, the buttress 22 and contact 24 assemblies are octagonal in cross-section where the buttresses 22 join to the substrate 16 and extend perpendicularly and upwardly from the substrate to a point where the sides slope inwardly to form a tapered tip 26 which is quadrilateral in cross- section. The tapered tip 26 is truncated short of forming a point.
The contacts 24 are four in number and are disposed to overlie alternate faces of the octagonal portion of the buttress 22. At the location where the buttress 22 tapers inwardly, the contacts 24 bend to conform to the slope of the taper. The contacts 24 extend through the substrate 16 of the connector component body 14 to form terminal ends 28 as may be best seen in Figures 5-9. The terminal ends 28 afford attachment of the contacts 24 to the conductors of cables or electronic devices such as circuit boards. The terminal ends 28 may be of any shape which is suitable and necessary to enable connection to a desired device.
The contacts 24 may be inserted through holes in the substrate 16 and simply overlie the buttresses 22, but are preferably molded as an integral part of the connector component 10 as the body 14 of the component 10 and the buttresses 22 are molded simultaneously. It is also preferred, although not necessary, that the contacts 24 be embedded in the buttresses 22 so that the outer surface of each contact 24 forms one of the octagonal sides of the buttress 22. As seen in Figure 8, the contacts 24 preferably have a trapezoidal cross-section which allows the material of the buttress 22 to flow behind the tapered sides of the trapezoidal shape during molding to lock the contact 24 to the buttress 22 and prevent movement of the contacts 24 away from the buttresses 22.
The contacts 24 are preferably tapered in the transverse direction, as best seen in Figure 1 and 3, so that the bent tips of the contacts 24 can extend more fully toward the end of the buttress 22 without interfering with each other. For the same reason, the bent tips are preferably coined so that the ends taper gradually in thickness from the junction of its straight portion to its end. The thickness taper is best seen in Figures 5 and 6 and preferably is such that the end is one-half the thickness of the remainder of the contact 24.
The female connector component 12 is best seen in Figures 2 and 4 and is formed of a molded body 30 and four contacts 32 arrayed to correspond to the position of the four contacts 24 of the male connector component 10 when the male and female connector components 10 and 12 are mated. The contacts 32 are cantilever beams extending from the female connector component 12 and are formed with bent ends 34 to prevent gouging of the male contacts 24 when the two are mated. The contacts 32 are preferably manufactured of the same materials as the male contacts 24, and are preferably molded in place as an integral part of the female connector component 12. The preferred materials for the female connector component 12 correspond to the preferred materials for the male connector component 10.
The reason for providing the tapered, bent tips of the male contacts 24 which overlie the tapered tip 26 of the buttresses 22 is illustrated in Figures 5 and 6. As the two connector components 10 and 12 approach each other for mating, the first contact is between the ends of the female contacts 32 and the male contacts 24. If the bent end of the male contacts 24 did not exist, the female contacts 32 would first touch the insulative polymeric material of the buttress 22. Eventual full mating of the contacts 24 and 32, as shown in Figure 7, would happen even without the bent portion of the male contacts 24 because the tapered tip 26 of the buttress would cause separation of the female contacts 32 and contact with the male contacts 24 as the components 10 and 12 are pushed together. However, the insulative material from which the buttresses 22 are formed is very abrasive and would quickly erode any plating on the female contacts 32 and eventually the base material. The bent tips of the male contacts 24 are provided so that initial contact is between the contacts 24 and 32 only, rather than between the contact 32 and the polymeric material comprising the buttresses 22.
Figures 9 and 10 illustrate another construction feature of the contacts 32 which is necessitated by the proximity of the contacts 32 of the construction just described. Although only the female connector component 12 is illustrated in Figure 9, the contact construction and arrangement can apply to either or both of the male connector component 10 and the female connector component 12. Reference will thus be made to both types of contacts 24 and 32.
The contacts 24, 32 must exit the connector components 10 and/or 12 in such a way that they do not interfere with each other. This is best accomplished as shown in Figure 10 by reducing the rectangular cross- section of the main body of the contacts 24, 32 to a square cross-section terminal section 36 extending from one side of the contact 24, 32. The contacts 24, 32 are then arranged with the square terminal sections 36 of opposed contacts 24, 32 extending from opposite ends of the elongate cross-section of the contacts 24, 32. In this way the terminal sections 36 may be bent perpendicular to the long dimension of the cross-section of the contacts 24, 32 toward the other contact 24 without extending over the point where the other terminal section 36 joins the other contact 24, 32.
The preferred square cross-section of the terminal sections 36 of the contacts 24, 32 additionally allows those sections 36 to be bent in any direction, that is either with or against the grain of the material from which the contact 24, 32 is made. However, the main body of the contact 24, 32 need not be rectangular as shown, nor need the terminal section 36 of the contact 24, 32 be square as shown. The main body of the contacts 24, 32 could be oval or, more generally, elongate, and the terminal section 36 could be circular in cross- section or have a cross-section which was simply generally uniform in cross-sectional dimensions.
The present invention has been described with respect to only a single embodiment. However, many variations will be apparent to those skilled in the art. For example, the number of contacts may any number and the shape of the buttress need not be octagonal. Also, less than all of the available sides of the buttress may have contacts associated with them. The contacts may be formed with curved rather than flat surfaces as shown, and the curvature may be in the transverse or longitudinal direction, or both. Finally, the arrangement of the terminal sections 36 shown in Figures 9 and 10 is only one example of the way these sections 36 may be arranged, many other configurations are possible or will be required depending upon the device to which the connector components 10 and 12 will be connected.
