An electrical terminal has a portion for force-fit reception in a hole in a substrate, the portion comprising a pair of beam members extending between first and second contact portions of the terminal, the beam members being bowed in two mutually perpendicular directions.
Description
iO46~02 This invention relates to an electrical terminal, and particularly to an electrical terminal having a portion for force-fit reception in a hole in a substrate.
In British Patent Specification ~o. 1149332 (7353) there iB dis-closed an electrical terminal comprising first and second contact portions joined by an intermediate mounting portion for force-fit reception in a hole in a substrate, the mounting portion comprising a pair of spaced beam members one end of each of which is ~oined to the first contact portion and the oth-er end of each of which is joined to the second contact portion, the beam members being bowed in opposite senses in a flrst direction perpendicular to the longitudinal axis of the terminal thereby resiliently to engage opposite -wall portions of a hole in a substrate when the mounting portion is received therein.
This known terminal has the disadvantages that the mounting portion thereof engages the hole in a substrate in which it is received at only two spaced locations, and is therefore normally able to move transversely rela- -~
tive to the substrate. ~his disadvantage could be minimised by making the hole $n the substrate of such dimensions that the hole embraces the mounting portion of the terminal. However, this requires very accurate dimensioning of the hole in the substrate, and can also lead to damage of the substrate ' ~ since the mounting portion of the terminal would not resiliently engage the wall of the hole in the substrate other than in the direction of bowine of the beam members o~ the mounting portion.
~n ~ According to this invention in an electrical terminal of the type described above, the beam members are also bowed in the same sense in a sec-ond direction perpendicular to said first direction and to the longitudinal axis of the terminal thereby resiliently to engage further opposite wall portions of the hole in the substrate when the mounting portion is received 10466(~2 therein.
The terminal of the present invention has the advantage that it resiliently engages the wall of a hole in a substrate in which the mounting portion is received, in two mutually perpendicular directions, and thus can be securely received with a minimum of wobble in holes within a relatively large dimensions tolerance range without fear of damaging the substrate.
The terminal of the present invention is preferably mounted in a rectangular cross-section hole in a substrate, for example a printed circuit board or a connector housing, whereby the two pairs of opposite wall por-tions of the hole engaged by the mounting portion of the terminal are on the two pairs of opposite walls of the hole.
The terminal of the present invention has the further advantage that the two beam members of the mounting portiOD function substantially independently of each other when received in a hole in a substrate and thus the terminal allows for manufacturing tolerances in the dimensions of the hole~and of the beam members themselves.
This invention will now be described by way of example with refer-ence to~the~drawingc, ln whlch~
Figure~l~is a front vlew of a terminal according to~the lnvention;
20~ Flgure~2 1s a #ide elevation of the terminal of Figure l;
Figure 3~ i8 a perspective view of the terminal of Figures l and 2;
Plgure 4;1s~a sectloned perspectlve view of four terminals as sho~wn~in Figures~l to~3, mounted in individ 1 holes in a substrate;
Figure 5~is a;~front~view of~a second embodiment of terminal accord-to thè;~lnvention~ and~
Figure~6~1c~a~cide~elevct1on of the terminal of Figure 5.
Referrlng~flrst~to~Flgures 1 to 3, the terminal here shown is f ~ d~of~reslilent me*al and comprises a first contact portion l, a second ~ 2 -104~60Z
contact portion 2, and an intermediate mounting portion 3. The form of the contact portions 1 and 2 is not critical to the present invention save that one thereof can pass through a hole in which the mounting portion 3 is to be received, and thus the contact portions 1 and 2 will not be described in any detail.
The mounting portion 3 comprises a pair of spaced beam members 4 and 5 which are separated by a hole 6. One end of each of the beam members 4 and 5 is connected to the contact portion 1, and the other end of each thereof is connected to the contact portion 2.
As best seen in Figure 1, the beam members 4 and 5 are bowed in -~
opposite senses, that is awa~ from each other at their centres, in a first direction perpendicular to the longitudinal axis of the terminal.
As best seen in Figure 2, the beam members 4 and 5 are also bowed in the same sense, that is to the right as seen in Figure 2, in a second direction perpendicular to the first direction of bowing shown in Figure 1, and to the longitudinal axis of the terminal.
Referring now to Figure 4 also, this figure shows four of the ter-minals of Figures 1 to 3 mounted in individual holes 7 in a substrate ô.
As shown, each hole 7 is rectangular in cross-section, and the mounting portion 3 of a terminal is received therein with the beam portions 4 and 5 re~iliently deformed in both their directions of bowing. The beam portions 4 and 5 are thus resilientl~ engaged with portions of each wall of :
the hole 7 and exerts forces against these wall portions as indicated by the arrows F.
As shown in Figures I and 2, the terminal has a reduced width por-ion 9 between the contact portion 2 and the unting portion 3, this pro-~ viding a pair of shoulders 10 which face the mounting portion 3. As shown s~ in Figure 4, the portion 9 can be twisted through ~0 such that with the ~ - 3 -.~ ~
': : . ' '': '' ' . ' - . ' . . . .
104~02 mounting portion 3 received in the hole 7, the shoulders 10 engage a surface of the substrate 8 to limit longitudinal movement of the terminal in one direction relative to the substrate 8.
Referring now to Figures 5 and 6, the terminal here shown is sim-ilar to that of Figures 1 to 4, save that the beam portions 4 and 5 are shaped to give the mounting portion 3 an overall wedge shape as shown in Figure 5 rather than the uniformly bowed shape of the terminal of Figures 1 to 4, and that there is no reduced width portion corresponding to the por-tion 9 of the terminal of Figures 1 to 4.
Thus, the terminal of Figures 5 and 6 is not intended to be twist-ed as is the terminal of Figures 1 to 4, but is intended to be inserted into a hole in a substrate with the contact part 2 leading, rather than with the ~ .
contact portion 1 leading as is the terminal of Figures 1 to 4.

This known terminal has the disadvantages that the mounting portion thereof engages the hole in a substrate in which it is received at only two spaced locations, and is therefore normally able to move transversely rela- -~

~n ~ According to this invention in an electrical terminal of the type described above, the beam members are also bowed in the same sense in a sec-ond direction perpendicular to said first direction and to the longitudinal axis of the terminal thereby resiliently to engage further opposite wall portions of the hole in the substrate when the mounting portion is received 10466(~2 therein.
The terminal of the present invention has the advantage that it resiliently engages the wall of a hole in a substrate in which the mounting portion is received, in two mutually perpendicular directions, and thus can be securely received with a minimum of wobble in holes within a relatively large dimensions tolerance range without fear of damaging the substrate.

The terminal of the present invention has the further advantage that the two beam members of the mounting portiOD function substantially independently of each other when received in a hole in a substrate and thus the terminal allows for manufacturing tolerances in the dimensions of the hole~and of the beam members themselves.
This invention will now be described by way of example with refer-ence to~the~drawingc, ln whlch~
Figure~l~is a front vlew of a terminal according to~the lnvention;

Figure 5~is a;~front~view of~a second embodiment of terminal accord-to thè;~lnvention~ and~
Figure~6~1c~a~cide~elevct1on of the terminal of Figure 5.
Referrlng~flrst~to~Flgures 1 to 3, the terminal here shown is f ~ d~of~reslilent me*al and comprises a first contact portion l, a second ~ 2 -104~60Z
contact portion 2, and an intermediate mounting portion 3. The form of the contact portions 1 and 2 is not critical to the present invention save that one thereof can pass through a hole in which the mounting portion 3 is to be received, and thus the contact portions 1 and 2 will not be described in any detail.
The mounting portion 3 comprises a pair of spaced beam members 4 and 5 which are separated by a hole 6. One end of each of the beam members 4 and 5 is connected to the contact portion 1, and the other end of each thereof is connected to the contact portion 2.
As best seen in Figure 1, the beam members 4 and 5 are bowed in -~
opposite senses, that is awa~ from each other at their centres, in a first direction perpendicular to the longitudinal axis of the terminal.
As best seen in Figure 2, the beam members 4 and 5 are also bowed in the same sense, that is to the right as seen in Figure 2, in a second direction perpendicular to the first direction of bowing shown in Figure 1, and to the longitudinal axis of the terminal.
Referring now to Figure 4 also, this figure shows four of the ter-minals of Figures 1 to 3 mounted in individual holes 7 in a substrate ô.
As shown, each hole 7 is rectangular in cross-section, and the mounting portion 3 of a terminal is received therein with the beam portions 4 and 5 re~iliently deformed in both their directions of bowing. The beam portions 4 and 5 are thus resilientl~ engaged with portions of each wall of :
the hole 7 and exerts forces against these wall portions as indicated by the arrows F.
As shown in Figures I and 2, the terminal has a reduced width por-ion 9 between the contact portion 2 and the unting portion 3, this pro-~ viding a pair of shoulders 10 which face the mounting portion 3. As shown s~ in Figure 4, the portion 9 can be twisted through ~0 such that with the ~ - 3 -.~ ~

104~02 mounting portion 3 received in the hole 7, the shoulders 10 engage a surface of the substrate 8 to limit longitudinal movement of the terminal in one direction relative to the substrate 8.
Referring now to Figures 5 and 6, the terminal here shown is sim-ilar to that of Figures 1 to 4, save that the beam portions 4 and 5 are shaped to give the mounting portion 3 an overall wedge shape as shown in Figure 5 rather than the uniformly bowed shape of the terminal of Figures 1 to 4, and that there is no reduced width portion corresponding to the por-tion 9 of the terminal of Figures 1 to 4.
Thus, the terminal of Figures 5 and 6 is not intended to be twist-ed as is the terminal of Figures 1 to 4, but is intended to be inserted into a hole in a substrate with the contact part 2 leading, rather than with the ~ .
contact portion 1 leading as is the terminal of Figures 1 to 4.
