Description

BACKGROUND

This invention relates in general to printed circuit board (PCB) assemblies having a PCB and electrical terminals attached thereto. In particular, this invention relates to an improved electrical terminal for such a PCB assembly that facilitates more efficient and effective placement of a plurality of the improved electrical terminals on the PCB.

Such PCB assemblies may be found in a variety of applications, such as power-distribution systems or junction boxes that are used to manage power distribution in automotive vehicles. Junction boxes typically include housings and a printed circuit board with electrical terminals, fuses, relays, circuit breakers, and other electrical devices mounted thereto. Electrical devices, such as connectors and wiring harnesses, may be connected to the terminals through the housings.

The electrical terminals may include terminal blades, forked female terminals, and/or portions having any other desired shape, and combinations thereof, that extend from one or both surfaces of the PCB.

The terminals may include insertion tabs that extend substantially transversely from the terminal. Each insertion tab provides an engagement surface against which an insertion tool may engage and urge the terminal through an aperture in the PCB, thereby mounting the terminal to the PCB. The insertion tabs are typically flat and in the same plane as a body of the terminal.

A plurality of terminals may be mounted in line on the PCB such that the terminals are substantially co-planar. When adjacent terminals are mounted to the PCB in this manner, the insertion tabs may also be co-planar. Adjacent terminals are typically mounted with a minimum distance therebetween to ensure that the adjacent electronically conductive terminals do not touch each other and/or to provide space for a wall of a housing that may be mounted about each terminal. A minimum center line distance between adjacent terminals is thus determined by the size of the insertion tabs that extend substantially transversely from, and in the same plane as, the body of the terminal.

End users of conventional junction boxes however, may desire a reduced package size for the junction box, thus requiring smaller PCB assemblies within the smaller junction box. It is therefore desirable to provide a terminal design that allows adjacent terminals to be mounted closer together, thus reducing the center line distance between adjacent terminals and allowing the size of the PCB assembly and the package size of the junction box to be reduced.

SUMMARY OF THE INVENTION

This invention relates to an improved PCB assembly that allows adjacent terminals mounted to the PCB to be mounted closer together than is possible in conventional PCB assemblies. One embodiment of the PCB assembly includes a PCB and first and second electrical terminals mounted thereto. The first electrical terminal comprises a body having a first end and a second end, a mounting member extending outwardly from the first end configured for insertion into an aperture formed in the PCB, shoulders defined adjacent the mounting member, and a first insertion tab extending outwardly from the body at the first end thereof. The second electrical terminal is mounted adjacent the first electrical terminal and comprises a body having a first end and a second end, a mounting member extending outwardly from the first end configured for insertion into an aperture formed in the PCB, shoulders defined adjacent the mounting member, and a second insertion tab extending outwardly from the body at the first end thereof. The first insertion tab and the second insertion tab are axially spaced apart.

Various advantages of the invention will become apparent to those skilled in the art from the following detailed description, when read in view of the accompanying drawings.

DETAILED DESCRIPTION

The present invention will now be described with occasional reference to the specific embodiments of the invention. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Referring now to FIG. 1, there is illustrated a portion of a conventional PCB assembly 10. The PCB assembly 10 illustrated in FIG. 1 includes a PCB 12 having a first major surface 12a (upper surface when viewing FIG. 1), a second major surface 12b (lower surface when viewing FIG. 1), and a plurality of tuning fork type electrical terminals 14. The terminals 14 are inserted in respective terminal apertures 12c formed through the PCB 12.

As shown in FIG. 1, each terminal 14 has a body 16 including a first end 16a and a second end 16b. The first end 16a has a mounting post 18 extending therefrom and defines shoulders 20 adjacent the mounting post 18. The mounting post 18 is configured for insertion and mounting within the apertures 12c of the PCB 12, and the shoulders 20 are configured to engage the second major surface 12b of the PCB 12.

The second end 16b is configured as a tuning fork type female terminal and includes two substantially parallel prongs 22 defining a slot 23 therebetween for receiving an electrical engagement feature, such as a terminal blade, of another electrical device (not shown). Connection protrusions or members 22a extend inwardly (into the slot 23) from the prongs 22 and are configured to provide an improved frictional fit of the terminal blade or other electrical engagement feature received in the slot 23.

Insertion tabs 24 extend outwardly from the terminal body 16 between the shoulders 20 and the tuning fork type female terminal 16b and are spaced a distance apart from the shoulders 20. In a known manner, the insertion tabs 24 extend substantially transversely from, and in the same plane as, the terminal body 16.

As shown in FIG. 1, the terminals 14 are identical. As a result, when they are mounted to the PCB 12, the insertions tabs 24 of adjacent terminals 14 are co-planar and aligned linearly along a line L1. Accordingly, a minimum centerline distance CL1 between adjacent terminals 14 is limited by the proximity of adjacent insertion tabs 24 to one another. For example, in the embodiment illustrated in FIG. 1, each of the terminals 14 has a width W1, measured from outside surfaces of the insertion tabs 24, of about 5.0 mm to about 5.2 mm. When mounted in a conventional manner as shown, the centerlines of adjacent terminals 14 are spaced apart by a distance CL1 of between about 6.5 mm and about 6.7 mm.

Referring now to FIGS. 4 through 9, there are illustrated alternative embodiments of electrical terminals, described in detail below, suitable for use in an improved PCB assembly 90, shown in FIGS. 2 and 3.

Referring to FIG. 4, a first embodiment of an electrical terminal is shown at 30. The electrical terminal 30 includes a mounting member or first end 30a and a first embodiment of a second end 30b.

As best shown in FIG. 3, the mounting portion 36 has a width W3 larger than the width W2 of the blade 30a. The illustrated mounting portion 36 has a width W3 between about 3.4 mm and about 3.6 mm. The mounting portion 36 is configured for insertion and mounting within the apertures 12c of the PCB 12. Alternatively, the terminal 30 may be formed without the mounting portion 36, if desired.

Insertion tabs 38 extend outwardly from the tuning fork type female terminal 30 between the shoulders 34 and the prongs 32, and include a first surface 38a and a second or tool-engagement surface 38b. The insertion tabs 38 are spaced a distance apart from the shoulders 34. In the embodiment illustrated, the first surface 38a is spaced between about 2.3 mm and about 2.5 mm from the shoulders 34. The electrical terminal 30 has the width W1, measured from outside surfaces of the insertion tabs 38 of about 5.0 mm to about 5.2 mm, as shown in FIG. 3.

A portion 37 of the tuning fork type female terminal 30b between the insertion tabs 38 and the shoulders 34 has a width W6 between about 3.9 mm and about 4.1 mm, as also shown in FIG. 3.

The dimensions of the electrical terminal 30, including the blade 30a and the tuning fork type female terminal 30b described above are not limited to the dimensions disclosed and may have any other desired dimensions.

Referring to FIG. 5, a second embodiment of an electrical terminal is shown at 40. The electrical terminal 40 is similar to the electrical terminal 30 and includes the first end 30a configured as the blade and a second embodiment of the second end 40b.

In the tuning fork type female terminal 40b, insertion tabs 42 are provided that are substantially identical to the insertion tabs 38, including a first surface 42a and a second or tool-engagement surface 42b, but extending outwardly from the tuning fork type female terminal 40b at the interface of the blade 30a and the tuning fork type female terminal 40b. Thus, the first surfaces 42a of the insertion tabs 42 define shoulders 44.

The electrical terminal 40 has the width W1 measured from the outside surfaces of the insertion tabs 42, of about 5.0 mm to about 5.2 mm, as shown in FIG. 5.

Referring to FIG. 6, a third embodiment of an electrical terminal is shown at 50. The electrical terminal 50 is similar to the electrical terminal 30 and includes a first end configured as a blade 50a and a third embodiment of the second end 50b.

The dimensions of the electrical terminal 50, including the blade 50a and the tuning fork type female terminal 50b described above, are not limited to the dimensions disclosed and may have any other desired dimensions.

Referring to FIG. 7, a fourth embodiment of an electrical terminal is shown at 60. The electrical terminal 60 is similar to the electrical terminal 50 and includes the first end configured as the blade 50a having the width W4, the mounting portion 52 having the width W5, the tuning fork type female terminal 40b, and the insertion tabs 42.

The insertion tabs 42 include the first surface 42a and the second or tool-engagement surface 42b, wherein the first surfaces 42a define the shoulders 44.

Referring to FIG. 8, a fifth embodiment of an electrical terminal is shown at 70. The electrical terminal 70 includes a body 71 having a first end 71a and a second end 71b. The first end 71a has a mounting post 73 extending therefrom and defines the shoulders 34 adjacent the mounting post 73. The body 71 is similar to the second end 30b and includes the two substantially parallel prongs 32 defining the slot 33 therebetween. Each prong 32 includes the connection protrusion or member 32a. The body 71 further includes the insertion tabs 38 extending outwardly from the body 71 between the shoulders 34 and the prongs 32. Each insertion tabs 38 includes the first surface 38a and the second or tool-engagement surface 38b. The insertion tabs 38 are spaced a distance apart from the shoulders 34. In the embodiment illustrated, the first surface 38a is spaced between about 2.3 mm and about 2.5 mm from the shoulders 34.

Referring to FIG. 9, a sixth embodiment of an electrical terminal is shown at 80. The electrical terminal 80 includes a body 81 having first end 81a and a second end 81b. The first end 81a has a mounting post 83 extending therefrom. The body 81 is similar to the second end 40b and includes the two substantially parallel prongs 32 defining the slot 33 therebetween. Each prong 32 includes the connection protrusion or member 32a. The body 81 further includes the insertion tabs 42 extending outwardly from the body 81 at the first end 81a thereof and include the first surface 42a and the second or tool-engagement surface 42b, wherein the first surface 42a of the insertion tabs 42 defines the shoulders 44.

The dimensions of the electrical terminals 70 and 80, including the component parts thereof, described above are not limited to the dimensions disclosed, and may have any other desired dimensions.

The illustrated mounting post 83 has a tapered distal end. It will be understood that the terminals 70 and 80 may have the mounting post 73, as shown in FIG. 8, or the tapered mounting post 83, as shown in FIG. 9.

As described above, the electrical terminals 40, 60, and 80 are similar in that the insertion tabs 42 define the shoulders 44. Similarly, the electrical terminals 30, 50, and 70 are similar in that the insertion tabs 38 are equidistant from the shoulders 34, and therefore equidistant from the second major surface 12b of the PCB 12.

It will be understood that the insertion tabs 42 on the electrical terminals 40, 60, and the insertion tabs 38 on the electrical terminals 30, 50, and 70 may be formed at any desired axial location, such that when assembled in a PCB assembly, such as shown at 90 in FIG. 3, each insertion tab 38 may be axially spaced apart from an adjacent insertion tab 42 a distance D1 for reasons described below. In the illustrated embodiment, the distance D1 is about 0.5 mm. Alternatively, the distance D1 may be any desired distance, including a distance less than about 0.5 mm and a distance greater than about 0.5 mm.

Referring now to FIGS. 2 and 3, there is illustrated at 90 an improved PCB assembly shown during first and second steps, respectively, of a method of assembling the improved PCB assembly 90 in accordance with the invention.

As shown in FIG. 2, an insertion tool 92 includes a body 94 having a cavity 94a, which is configured to receive the tuning fork type female terminal 40b, and a terminal-engagement surfaces 94b. The tool 92 is disposed about the tuning fork type female terminal 40b of the terminal 40 such that the terminal-engagement surfaces 94b engage the tool-engagement surfaces 42b of the insertion tabs 42. A force is applied to the tool 92 in the direction of the arrow A, urging the blade 30a into the aperture 12c until the shoulders 44 engage, and are seated against, the second major surface 12b, thereby mounting the terminal 40 to the PCB 12. Solder (not shown) may then be applied to the terminal 40 on one or both of the first and second major surfaces 12a and 12b, respectively, to provide an electrical connection therebetween.

In FIG. 2, the terminals 60 and 80 are shown subsequent to being assembled in the same manner as the terminal 40. Although the tool-engagement surface 42b of the terminal 40 is shown as the second surface of the insertion tabs 42, the terminals 40, 60, and 80 may be configured such that the tool-engagement surface 42b is defined on any desired portion of the terminals 40, 60, and 80. Similarly, the tool 92 may be configured such that the terminal-engagement surfaces 94b are defined on any desired portion of the tool 92 that engage the terminals 40, 60, and 80 and allow the terminals 40, 60, and 80 to be urged through the apertures 12c and into contact with the second major surface 12b of the PCB 12. Each terminal 60 and 80 may also be mounted to the PCB 12 in the same manner as the terminal 40, wherein the blade 50a or the mounting post 83 is urged into an aperture 12c of the PCB 12.

As shown in FIG. 3, the insertion tool 92 is disposed about the tuning fork type female terminal 30b of the terminal 30, such that the terminal-engagement surfaces 94b engage the tool-engagement surfaces 38b of the insertion tabs 38. A force is applied to the tool 92 in the direction of the arrow B, urging the blade 30a into the aperture 12c until the shoulders 34 engage, and are seated against, the second major surface 12b. Solder (not shown) may then be applied to the terminal 30 on one or both of the first and second major surfaces 12a and 12b, respectively, to provide an electrical connection therebetween.

Each terminal 50 and 70 may also be mounted to the PCB 12 in the same manner as the terminal 30, wherein the blade 50a or the mounting post 73 is urged into an aperture 12c of the PCB 12. In FIG. 3, the terminals 50 and 70 are shown subsequent to being assembled in the same manner as the terminal 30.

As further shown in FIG. 3, when mounted to the PCB 12, the insertion tabs 42 of the terminals 40, 60, and 80 are co-planar and aligned linearly along a line L2. Similarly, when mounted to the PCB 12, the insertion tabs 38 of the terminals 30, 50, and 70 are co-planar and aligned linearly along a line L3. In the illustrated embodiment, the terminals are mounted such that any one of the terminals 30, 50, and 70 are mounted in an alternating manner with any one of the terminals 40, 60, and 80. This arrangement ensures that a terminal with the insertion tabs 38 is adjacent a terminal with the insertion tabs 42.

As shown in FIG. 3, the insertion tabs 42 of the terminals 40, 60, and 80 and the insertion tabs 38 of the terminals 30, 50, and 70 are axially spaced apart the distance D1. This axial spacing allows adjacent terminals to be mounted more closely together than is possible in conventional PCB assemblies, such as the PCB assembly 10 shown in FIG. 1. Accordingly, a minimum centerline distance CL2 between any two adjacent terminals illustrated in FIG. 3 may be smaller than the centerline distance between terminals in conventional PCB assemblies, such as the PCB assembly 10 illustrated in FIG. 1. For example, in the exemplary embodiment illustrated in FIG. 3, the centerline distance CL2 is between about 5.0 mm and about 5.2 mm. Alternatively, the centerline distance CL2 may be any desired distance, including a distance less than about 5.0 mm and a distance greater than about 5.2 mm.

In the illustrated embodiment, adjacent terminals are transversely spaced apart such that an outside surface 38c (a representative example of which is shown in the terminal 70 in FIG. 3) of the insertion tabs 38 may be spaced apart a distance D2 from an outside surface 42c (a representative example of which is shown in the terminal 80 in FIG. 3) of the insertion tabs 42. In the illustrated embodiment, the distance D2 is about 0.5 mm. Alternatively, the distance D2 may be any desired distance, including a distance less than about 0.5 mm and a distance greater than about 0.5 mm.

As in a conventional PCB assembly, the electrically conductive terminals of the improved PCB assembly 90 may not contact one another. It will be understood that any two terminals (30, 40, 50, 60, 70, and 80) of the improved PCB assembly 90 may be arranged in any position relative to one another such that they do not touch one another.

For example, adjacent terminals may be mounted such that their corresponding insertion tabs, 38 and 42, are positioned in an overlapping arrangement, but spaced apart a distance such that they do not touch one another.

Further, during assembly of the illustrated improved PCB assembly 90, the space created by the distance D2 between the outside surfaces 38c and the outside surfaces 42c allows for the insertion of the tool 92 in the space between adjacent terminals. The distance D2 between adjacent terminals also has the benefit of providing space for a portion of a non-conductive element, such as a wall of a connector body or of a junction box body, to be disposed and fixed therein between the adjacent terminals. It will be understood however, that the distance D2 need not be large enough to allow for the insertion of the tool 92 or for a portion of the non-conductive element.

The exemplary embodiments of the electrical terminals 30, 40, 50, 60, 70 and 80 illustrated in FIGS. 4 through 9 include first ends configured as blades and second ends configured as tuning fork type female terminals. It will be understood that the first ends of the electrical terminals 30, 40, 50, 60, 70 and 80 may have any design, shape or configuration suitable for use in a PCB. Similarly, the second ends of the electrical terminals 30, 40, 50, 60, 70 and 80 may have any design, shape or configuration suitable for use in a PCB and requiring one or more insertion tabs thereon.

Additionally, each of the exemplary embodiments of the electrical terminals 30, 40, 50, 60, 70 and 80 illustrated in FIGS. 4 through 9 include two insertion tabs formed thereon. It will be understood that the electrical terminals 30, 40, 50, 60, 70 and 80 may have any desired number of insertion tabs formed thereon, including having only one insertion tabs formed thereon.

The principle and mode of operation of the invention have been described in its preferred embodiments. However, it should be noted that the invention described herein may be practiced otherwise than as specifically illustrated and described without departing from its scope.
