Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. § 119 to Chinese Patent Application No. 202021428084.6 filed on Jul. 20, 2020, the entire disclosure of which is incorporated herein by reference.

FIELD OF THE INVENTION

The present disclosure relates to a conductive terminal, and in particular, to a conductive terminal suitable for insertion into circuit board.

BACKGROUND

Conductive terminals are often required to be inserted into a circuit board, and maintained in a particular orientation therewith (e.g., perpendicular to a surface of the circuit board) during manufacturing and/or use. Terminals of the prior art accomplish this via the formation a single supporting wing on each of left and right sides of the terminal. This single supporting wing structure, however, is asymmetrical relative to the front and rear sides of the terminal. As a result, it remains difficult to ensure the desired position of the terminal relative to the circuit board.

SUMMARY

A conductive terminal according to an embodiment of the present disclosure comprises a pair of abutting plate-shaped body parts having a front side and a rear side opposite to each other in a thickness direction, and a left side and a right side opposite to each other in a width direction. An elongated insertion part extends from one of the two body parts for engaging with a circuit board. The terminal further includes a pair of first supporting wings arranged on the front side and the rear side of the body parts and aligned with each other at edges of the left side of the two body parts, respectively, and a pair of second supporting wings arranged on the front side and the rear side of the two body parts and aligned with each other at edges of the right side of the two body parts, respectively.

It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.

According to one aspect of the disclosure, a conductive terminal is provided comprising a pair of abutting plate-shaped body parts having opposite front and rear sides, and opposite left and right sides. An elongated insertion part extends from one of the two body parts for engaging with a circuit board. The terminal further includes a pair of first supporting wings arranged on the front side and the rear side of the body parts and aligned with each other at edges of the left side of the two body parts, respectively, and a pair of second supporting wings arranged on the front side and the rear side of the two body parts and aligned with each other at edges of the right side of the two body parts, respectively.

FIG. 1 shows a schematic perspective view of a conductive terminal 100 according to an exemplary embodiment of the present disclosure, and FIG. 4 shows a plan expanded view of the conductive terminal 100 shown in FIG. 1. As shown in FIGS. 1 and 4, in one embodiment the conductive terminal 100 is a single integral piece formed by folding a single metal sheet. The conductive terminal 100 includes two body parts 110 and an insertion part in the form of a pair of connection legs 120. The two body parts 110 are plate-shaped and stacked together. Further, the two body parts 110 have a front side and a rear side opposite to each other in a thickness direction thereof, as well as a left side and a right side opposite to each other in a width direction thereof. The insertion part extends from one of the two body parts 110 by a first predetermined distance.

FIG. 2 shows a schematic perspective view of the conductive terminal 100 shown in FIG. 1 when viewed from one side in the thickness direction thereof, and FIG. 3 shows a schematic perspective view of the conductive terminal 100 shown in FIG. 1 when viewed obliquely from one side in the width direction thereof. As shown in FIGS. 1-3, the conductive terminal 100 further includes a pair of first supporting wings or feet 111a and a pair of second supporting wings or feet 111b. The pair of first supporting wings 111a are symmetrically arranged on the front side and the rear side of the body parts 110 and aligned with each other at edges of the left side of the two body parts 110, respectively. The pair of second supporting wings 111b are symmetrically arranged on the front side and the rear side of the two body parts 110 and aligned with each other at edges of the right side of the two body parts 110, respectively.

FIG. 5 shows a schematic view of the conductive terminal 100 shown in FIG. 1 inserted into a slot 210 of a circuit board 200. As shown in FIGS. 1-5, when the conductive terminal 100 is inserted into the slot 210 of the circuit board 200, the pair of first supporting wings 111a and the pair of second supporting wings 111b are supported on a surface of the circuit board 200 such that the conductive terminal 100 is oriented perpendicularly to the circuit board 200. Specifically, the pair of first supporting wings 111a and the pair of second supporting wings 111b have supporting bottom surfaces located in the same plane. As the conductive terminal 100 is inserted into the slot 210 in the circuit board 200, the supporting bottom surfaces of the pair of first supporting wings 111a and the pair of second supporting wings 111b are brought in contact with the surface of the circuit board 200. The first supporting wings 111a and the second supporting wings 111b may be sheet-shaped and configured to be perpendicular to the surface of the circuit board 200 when supported on the circuit board 200.

The pair of first supporting wings 111a and the pair of second supporting wings 111b are identical to each other and are arranged symmetrically on the left side and the right side of the body parts 110. One of the pair of first supporting wings 111a extends forwards in the thickness direction of the respective body part 110 by a second predetermined distance, and the other extends rearwards in the thickness direction of the respective body part 110 by a third predetermined distance. The second predetermined distance may be equal to the third predetermined distance as shown in FIG. 3. In another embodiment, the second predetermined distance may be different from the third predetermined distance. Likewise, one of the pair of second supporting wings 111b extends forwards in the thickness direction of the respective body part 110 by a fourth predetermined distance, and the other extends rearwards in the thickness direction of the respective body part 110 by a fifth predetermined distance. The fourth predetermined distance may be equal to the fifth predetermined distance as shown in FIG. 3. In an embodiment, the fourth predetermined distance may be different from the fifth predetermined distance. According to embodiments, the second, the third, the fourth and the fifth predetermined distance may be equal to one another. However, they may be different from one another in other embodiments of the present disclosure.

As shown in FIGS. 1-5, at least one strip-shaped positioning protrusion 112a, 112b is formed on an outer surface of each of the two body parts 110. The at least one positioning protrusion 112a, 112b is adapted to contact a sidewall of the slot 210 to prevent the conductive terminal 100 from moving in the thickness direction of the body parts 110. The at least one positioning protrusion 112a, 112b includes a pair of first positioning protrusions 112a and a pair of second positioning protrusions 112b. The pair of first positioning protrusions 112a are symmetrically arranged on the front side and the rear side of the conductive terminal 100, and are formed on the two body parts 110 proximate the left side of the body parts 110, respectively. The pair of second positioning protrusions 112b are symmetrically arranged on the front side and the rear side of the conductive terminal 100 respectively and are formed on the two body parts 110 proximate the right side of the body parts 110. Moreover, an inclined guide surface 12a, 12b is formed on a lower part of the at least one positioning protrusion 112a, 112b to guide the body parts 110 as they are inserted into the slot 210 of the circuit board 200.

As set forth above, the insertion part of the conductive terminal 100 includes two connection legs 120 connected to a lower portion of one of the two body parts 110 at the left side and the right side respectively, and extending in a length direction of the body parts 110 by the first predetermined distance. The connection legs 120 may have an increased thickness and/or width at their distal ends.
