Abstract
A switch 16 having three contact pins 14 is plugged into three socket terminals 12 mounted on a printed circuit board 10. Each socket terminal 12 has an elongated socket member 28 of square shape formed by generally rectangular side walls 34. Each side wall has a cantilever spring 36 at one end 38 formed from a portion of the side wall and the cantilever springs have contacts 40 at their free ends which extend into the socket member 28 in an orthogonal arrangement for engaging at one of the contact pins 14.
Description
- This invention relates generally to electric socket terminals and, more particularly, to electric socket terminals which are used for connecting an electric component, such as a switch, having a plurality of contact pins in a set pattern to a number of conductors.
- The object of the invention is to provide a socket terminal having a socket member which accommodates manufacturing variations or tolerances in pin diameter, pin-to-pin location, pin angle and pin length while providing good retention and electrical connection with each pin.
- A feature of the invention is that the socket member has several independently sprung contacts which accommodate pin diameter and location variations.
- Another feature of the invention is that the socket is elongated and has relatively short contacts at the forward end for accommodating variations in pin angle and length.
- Another feature of the invention is that the contacts have beveled faces to provide a good lead-in for pin insertion.
- Other objects and features of the invention will become apparent to those skilled in the art as the disclosure is made in the following detailed description of a preferred embodiment of the invention as illustrated in the accompanying sheets of drawings in which:
- Figure 1 is an exploded perspective view of a switch having three contact pins in a set pattern and a printed circuit board having three electric socket terminals in accordance with this invention which are mounted thereon for receiving the three contact pins.
- Figure 2 is a plan view of a stamped sheet metal blank for making one of the electric socket terminals shown in Figure 1.
- Figure 3 is a longitudinal view of a typical one of the electric socket terminals and part of the printed circuit board in section, which are shown in Figure 1.
- Figure 4 is a section taken substantially along the line 4-4 of Figure 3 looking in the direction of the arrows.
- Figure 5 is a right end view taken from the line 5-5 of Figure 3.
- Figure 6 is a left end view taken from the line 6-6 of Figure 3.
- Figure 7 is a perspective view of the electric socket terminal shown in Figures 3 to 6.
- Referring now to the drawings, Figure 1 shows a printed circuit board 10 having three
electric socket terminals 12 mounted thereon, in a pattern corresponding to that of threecontact pins 14 projecting from a switch 16 which is to be plugged into the printed circuit board. - Printed circuit boards are well known in the art and typically comprise a
non-conductive base 18 of phenolic or other suitable hard plastic material and a plurality ofconductor strips 20 "printed" on a surface of the base in a predetermined arrangement to provide all or part of an electric circuit. Typically, electric socket terminals are attached to the printed circuit boards so that various electric components, such as the switch 16, can be plugged into the printed circuit board and thereby electrically connected into the circuit. - The printed circuit board 10 has a more or less conventional arrangement for mounting electric socket terminals, namely a number of
round holes 22 which extend through thebase 18 and enlargedcontact pads 24 of theconductors 20. See Figures 3, 4 and 5. - The
electric socket terminals 12 are identical and each is made by die forming a flat stamped blank 26 shown in Figure 2. - Referring now to Figures 3 to 7, the typical
electric socket terminal 12 has anelongated socket member 28 at one end for receiving one of thecontact pins 14 and an attachment means 30 at the opposite end for mounting the electric socket terminal on the printed circuit board 10 and electrically connecting it to one of theconductors 20. - The
elongated socket member 28 is formed by bending the flat blank 26 perpendicularly at thedashed lines 32 shown in Figure 2. Bending the blank 26 so, results in asocket member 28 of square shape formed by a plurality of generallyrectangular side walls 34, which are joined one to another along a longer side edge. In so forming thesocket member 28, one of theside walls 34 has aseam 35 where the edges of the bent blank come together. - Each
side wall 34 has acantilever spring 36 at theentrance end 38 of thesocket member 28 which is provided by an L-shaped slot 37 which separates a corner portion of the side wall from the remainder of the side wall. Eachcantilever spring 36 thus formed, projects in a direction transverse to the longitudinal centerline of theelongated socket member 28, that is in a direction from one of the longer side edges of its associated rectangular side wall toward an opposite longer side edge. While thecantilever springs 36 are shown as flat and rectangular, other shapes, for instance flat and trapezoidal, are possible. - Each of the
cantilever springs 36 has acontact 40 at the free end which extends inwardly into thesocket member 28 for engaging thecontact pin 14 when it is inserted into thesocket member 28 via theentrance end 38. - The
contacts 40 are provided by bending the free ends of thesprings 36 perpendicularly along thedashed bent lines 39 shown in Figure 2. Thecontacts 40 are preferably midway between the longer side of theirrespective side walls 34 so that eachcontact 40 is radially directed to the longitudinal centerline of thesocket member 28. When thesocket member 28 has a square shape eachcontact 40 lies diametrically opposite anothercontact 40 and the four contacts are orthogonally related as shown in Figure 6. Thecontacts 40 also have bevelededges 42 at theentrance end 38 to guide thecontact pin 14 into thesocket member 28. - The attachment means 30 is in the form of two bent tabs 44 which extend from the ends of
opposite side walls 34 at an end opposite theentrance end 38 of thesocket member 28. Thesocket terminal 12 is mounted on the circuit board 10 by snapping the tabs 44 through thehole 22, so that they wedge against thecontact pad 24 to secure thesocket terminal 12 and make an electrical connection with theconductor 20. The tabs 44 are then soldered to thecontact pad 24 as shown in Figure 5. - While the
socket terminal 12 is illustrated in connection with a printed circuit board, the invention relates primarily to thesocket member 28 for receiving a contact pin and, consequently, the socket terminal may be adapted for other connector systems. For instance, the socket terminal may be used in a connector body on a wiring harness simply by modifying the attachment means 30 to a conventional crimp barrel. - We wish it to be understood that we do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
