Description

High-current multi-input board-to-wire connector

[0001] The present invention relates to a high-current multi-input board-to-wire connector, and more specifically, to a high-current multi-input board-to-wire connector that suppresses interference with other wires caused by the rotation of a wire.

[0002] A board-to-wire connector using an angle type connector can install a single wire to the connector installed on the board using a fastening means such as a screw, and can transmit high current to a board with a printed pattern.

[0003] However, angle type connectors fixed with screws or the like may rotate despite the fastening strength, and especially if the fastening strength of the device on which the connector is installed is weakened due to vibration or other factors, the connector may rotate and come into contact with an adjacent connector, and there is a risk of a short circuit.

[0004] To prevent angle type connectors from rotating and coming into contact with other connectors, one could consider increasing the spacing between connectors, but this would increase wasted space and negatively affect design freedom. Therefore, a structure is required that can prevent the rotation of angle type connectors while efficiently utilizing space.

[0005] The technical problem that the present invention aims to solve is to provide a high-current multi-input board-to-wire connector that improves operational stability by suppressing interference with other wires caused by the rotation of the wire and enables efficient component placement.

[0006] The technical problems of the present invention are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art from the description below.

[0007] A high-current multi-input board-to-wire connector according to some embodiments of the present invention for solving the technical problem described above comprises: a board having a pattern formed thereon; a connector having a first surface having a plurality of through holes formed thereon, which is installed upright in the vertical direction of the board to be electrically connected to the pattern; a plurality of wires each having a fastening hole formed thereon that is aligned with any one of the plurality of through holes and which are arranged in contact with the first surface; and a screw that is inserted in a first direction into the fastening hole of the wire aligned with any one of the plurality of through holes and fastens the wire to the connector, wherein the connector includes a second surface that protrudes and extends in the first direction from both sides of the first surface.

[0008] In some embodiments of the present invention, the connector includes a bus bar in which the first surface and the second surface are integrally formed, and the second surface may be formed by bending at least a portion of the bus bar.

[0009] In some embodiments of the present invention, at least a portion of the first surface may be spaced apart from the board at a certain distance.

[0010] In some embodiments of the present invention, the second surface may support the connector by contacting the board at a base.

[0011] In some embodiments of the present invention, at least a portion of the first surface may further include a component mounted on the board in a space formed spaced apart from the board.

[0012] In some embodiments of the present invention, the invention may further include a burring that taps at least a portion of a fixing means penetrating one of the plurality of through holes on the opposite side of the first surface where the plurality of wires are arranged.

[0013] A high-current multi-input board-to-wire connector according to some other embodiments of the present invention comprises: a board having a pattern formed thereon; a connector including a wire connection portion installed upright in the vertical direction of the board to be electrically connected to the pattern, and having a plurality of wires arranged in alignment; and a plurality of wires connected to the board-to-wire connector through a connection portion fixedly installed in the wire connection portion, wherein the connector includes a rib that blocks at least a part of the connection portion so as not to rotate further when the connection portion of the wire arranged at the outermost edge among the plurality of wires rotates by more than a predetermined angle.

[0014] In some embodiments of the present invention, the rib may be extended and protrude in the vertical direction of the wire fastening portion on which the connecting portion is positioned.

[0015] In some embodiments of the present invention, the rib may form an L-shape together with the base of the wire fastening portion that contacts the board.

[0016] In some embodiments of the present invention, the connector includes a busbar to which the wire fastening portion and the rib are connected, and the rib may be formed by bending at least a portion of the busbar.

[0017] In some embodiments of the present invention, at least a portion of the wire fastening portion may be spaced apart from the board at a certain distance to form an airflow passage.

[0018] In some embodiments of the present invention, the components mounted on the board may further include at least a portion of the airflow passage and the components mounted on the board so as to overlap vertically.

[0019] Specific details of other embodiments are included in the detailed description and drawings.

[0020] According to the present invention, operational reliability can be improved by preventing wires connected to two adjacent connectors from short-circuiting due to the rotation of the terminals. In addition, as the possibility of contact between adjacent wires due to rotation is reduced, the separation distance between two adjacent connectors can also be reduced. Consequently, the placement efficiency of the components constituting the board-to-wire connector is increased, and the degree of design freedom can be increased accordingly.

[0021] The effects of the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description in the claims.

However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms.

[0031] FIG. 1 is a perspective view of a high-current multi-input board-to-wire connector according to one embodiment of the present invention, and FIG. 2 is an exploded perspective view.

[0032] Referring to FIG. 1 and FIG. 2, a high-current multi-input board-to-wire connector (1) according to one embodiment of the present invention may include a board (100), a connector (110), a plurality of wires (130), a fixing means (140), etc.

[0033] The board-to-wire connector (1) can perform high current transmission by electrically connecting a board (100) to a wire (130) through which high current flows. At this time, a structure that improves the connection reliability of multiple wires (130) may be included in the board-to-wire connector (1).

[0034] The board (100) may include a printed circuit board (PCB) with a wiring pattern printed on one or both sides. The board (100) may include an insulating material such as, for example, phenol, epoxy, Teflon, ceramic, and in some embodiments, the board (100) may include a multilayer substrate.

[0035] A connector (110) may be installed upright on the board (100). That is, the connector (110) may be fixedly installed upright in a third direction (D3) on one side of the board (100) on which a pattern is formed as shown in FIGS. 1 and 2. The connector (110) can electrically connect the board (100) and a plurality of wires (130) by contacting the pattern on the board (100).

[0036] The installation of the connector (110) on the board (100) may include, for example, forming coupling holes in the connector (110) and the board (100) and installing it using coupling means such as screws and nuts in the aligned coupling holes. However, the present invention is not limited thereto, and the connector (110) may be installed on the board (100) by soldering, or by a connection method such as press-fitting or press-fitting.

[0037] The connector (110) may include a first surface (111) to which a plurality of wires (130) are connected, and a second surface (112) that protrudes and extends from both sides of the first surface (111). As shown in FIGS. 1 and 2, the second surface (112) may be formed by extending in the first direction (D1) from both ends of the first surface (111) which extends long in the second direction (D2). Thus, the first surface (111) and the two second surfaces (112) formed at both ends of the first surface (111) may form a C-shape or a U-shape when viewed from above the board (100).

[0038] The connector (110) may include a busbar comprising a conductive metal material. That is, the connector (110) may have a structure in which the second surface (112) is formed by bending a busbar, in which the first surface (111) and the second surface (112) are integrally formed, at a predetermined point. Of course, the connector (110) of the present invention does not completely exclude the case where the second surface (112) is joined to the first surface (111) by a method such as welding, but considering the simplification of the manufacturing process, it would be preferable for the second surface (112) to be formed by bending it from the side.

[0039] A wire fastening portion may be formed on the first surface (111) to which a plurality of wires (130) are arranged. The wire fastening portion refers to an area on the first surface (111) where a plurality of wires (130) are aligned and arranged. A plurality of through holes (114) for fixing and installing a plurality of wires (130) may be formed in the wire fastening portion of the first surface (111).

[0040] The through hole (114) can be aligned with the fastening hole (134) formed in the angle (133) of the wire (130) in the first direction (D1), and the wire (130) can be fixedly installed on the first surface (111) by means of a screw (140) inserted into the through hole (114) and the fastening hole (134). Thus, the position of the through hole (114) may represent the assembly position of a plurality of wires (130).

[0041] In some embodiments of the present invention, at least a portion of the first surface (111) may have a structure spaced apart from the board (100). That is, as shown in FIGS. 1 and 2, a space (113) may be formed where a portion of the first surface (111) is spaced apart from the board (100). This space (113) forms a kind of airflow passage, which is advantageous for heat dissipation compared to a structure where the entire first surface (113) is in contact with the board (100).

[0042] In addition, in some embodiments, various components are mounted at locations on the board (100) corresponding to the space (113), thereby allowing for efficient use of the mounting space of the board (100). For example, circuit elements or separate connectors may be mounted in the space (113).

[0043] Meanwhile, even though a space (113) is formed, the first surface (111) and the second surface (112) have a C-shape or a U-shape as described above, thereby maintaining a robust support structure for the connector (110). Specifically, the part corresponding to the base (115) of the first surface (111), that is, the part in direct contact with the board (100), forms an L-shape with each of the second surfaces (111), thereby enabling robust support for the connector (110) itself and the connector (110) in which a plurality of wires (130) are combined and installed.

[0044] A plurality of wires (130) can be aligned and arranged on the first surface (111) of the connector (110). By coupling the plurality of wires (130) to the connector (110), they can be circuitously connected in parallel with respect to the board (100), and the connector (110) has the same potential.

[0045] Each of the plurality of wires (130) may include a terminal (133) and a line (132) connected to the terminal (133). In some embodiments of the present invention, the terminal (133) may be an angle that causes the wire to extend in a first direction (D1) perpendicular to the connection portion where the through hole (134) is formed. However, the present invention is not limited thereto, and the terminal (133) may have a shape in which each wire extends in a third direction (D3) without being bent.

[0046] As previously described, a fastening hole (134) is formed in the terminal (133), and the fastening hole (134) is aligned with the through hole (114) and fixedly installed by a screw (140).

[0047] Meanwhile, among the plurality of wires (130), there is a wire (131) located at the outermost edge, and this outermost wire (131) corresponds to the wire closest to the second surface (112) among the plurality of wires (130). The function of the connector (110) for the outermost wire (131) is explained using FIG. 3.

[0048] FIG. 3 is a front view of a high-current multi-input board-to-wire connector according to an embodiment of the present invention.

[0049] Referring to FIG. 3, the outermost wire (131) that is coupled to the first surface (111) by means of a screw (140) or screw, etc. may rotate clockwise or counterclockwise despite the strong fastening strength of the screw (140) coupling. That is, the wire (131) may be fixed immediately after assembly by fastening the screw (140), but if the fastening strength of the screw (140) weakens due to repeated vibration or other reasons after mounting in the product, the wire (131) may rotate clockwise or counterclockwise.

[0050] At this time, contact between adjacent wires among the plurality of wires (130) may not be a major problem. That is, the connector (110) to which the plurality of wires (130) are connected may have the same potential during current transmission, and even if adjacent wires come into contact, a fatal short circuit may not occur. In addition, as shown in FIG. 3, the plurality of wires (130) may be aligned with a significantly short spacing between them, so there is little room for rotation, whether clockwise or counterclockwise.

[0051] However, as shown in FIG. 3, wires (130, 230) connected to adjacent connectors (110, 210) may have different potentials, so contact must be prevented. In the present invention, when the terminal (133) of the outermost wire (131) rotates beyond a predetermined angle, the rib (second surface) contacts the terminal (133) and blocks it, thereby preventing contact and short circuit with another outermost wire (231) connected to an adjacent connector (210).

[0052] Accordingly, the board-to-wire connector (1) according to an embodiment of the present invention can improve operational reliability by preventing wires connected to two adjacent connectors (110, 210) from being short-circuited by rotation of the terminal. In addition, as the possibility of contact between adjacent wires due to rotation is reduced, the distance between two adjacent connectors (110, 210) can also be reduced. Therefore, the placement efficiency of the elements constituting the board-to-wire connector (1) is increased, and the degree of design freedom can be increased accordingly.

[0053] FIG. 4 is a rear view of a high-current multi-input board-to-wire connector according to one embodiment of the present invention.

[0054] Referring to FIG. 4, a high-current multi-input board-to-wire connector according to one embodiment of the present invention may include a burring tab (142) that is coupled to a body (141) of a screw penetrating a first surface (111).

[0055] It is also possible to connect a separate PEM nut to the connector (110) to form a thread that connects with the body (141) of the screw. However, to minimize the space where multiple wires (130) are connected and to reduce the size of the connector (110), a burring process may be performed to connect with the screw (140), and a connection structure may be formed in which the thread inside the burring tab (142) and the body (141) of the screw are connected.

[0056] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without changing its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
