Technology Field

[0001] The present invention relates to a connector, and more specifically, to a connector assembly compatible with busbars of various structures according to a design layout. Background Technology

[0003] Generally, electrical devices are located within a part of an electrical system to transmit power or electrical signals or information, and are used to connect wires on both sides that are separated; wire harnessing is performed on these electrical devices to supply electricity.

[0004] Busbar / wire harness connections are made to these electrical devices to supply electricity.

[0005] A connector is typically used for this power supply operation, and current flows through the connector by the mutual electrical coupling of the female connector and the male connector.

[0006] Meanwhile, in conventional mail connectors, the busbar, the protective part protecting the busbar, and the connector housing are formed as a single unit.

[0007] Therefore, conventionally, since the connector housing, busbar, and protective part of the male connector are formed as an integrated structure, there is a problem in that if the position or angle at which the male connector is assembled with the surrounding case changes, the busbar and protective part are also assembled at the changed position or angle.

[0008] In other words, since the position or angle required for connection to the busbar varies depending on the surrounding design layout, there is the inconvenience of having to continuously develop and modify the entire connector to meet the requirements of that design layout.

[0009] For the reasons mentioned above, the relevant field is seeking ways to make the connector housing, busbar, and protective part of the male connector compatible with the design layout requirements, but satisfactory results have not been obtained to date. The problem to be solved

[0011] The present invention, aimed at solving the aforementioned problems, provides a connector assembly in which the connector housing, busbar, and protective part of a mail connector are compatible with the requirements of the design layout.

[0014] A connector assembly according to an embodiment of the present invention for achieving the above-described purpose comprises: a connector housing having a plurality of terminals accommodated therein; a connector block disposed on the rear surface of the connector housing; a bus bar that penetrates the connector block and is selectively inserted into or removed from the rear surface of the connector housing; a protective part coupled to the rear surface of the connector block and exposing the upper surface of the bus bar; and a fixing part that prevents the bus bar from being removed from the connector housing. The connector housing includes an insertion groove into which the bus bar is inserted, and the bus bar is inserted into or removed from the insertion groove in a sliding manner along the front-rear direction, and the surface inserted into the insertion groove is formed parallel to the front-rear direction so as not to be coupled to the connector housing. The fixing part is provided at the rear end of the bus bar with respect to the front-rear direction to fix the front-rear position of the bus bar, and is detachably fitted into the protective part.

[0015] The connector housing includes: a body portion; a protrusion protruding from the rear of the body portion into which the bus bar is inserted; and a flange portion extending in a band shape along the perimeter of the outer surface between the body portion and the protrusion portion to restrict the movement of the connector block.

[0016] The connector block is coupled to the flange portion, and the protective portion is coupled to the connector block.

[0017] The connector block is formed with: a through hole through which the protrusion passes; a guide portion extending from the peripheral portions on both sides of the through hole to guide the coupling direction of the protective portion; and a coupling portion to which a bolt is fastened so as to connect the protective portion.

[0018] The above protrusion protrudes from the above through hole.

[0019] On both sides of the protective part, fitting protrusions protruding outward are formed, and on the fixed part, a fitting groove is formed at a position corresponding to the fitting protrusions, and the protective part and the fixed part are joined by a fitting method through the fitting protrusions and the fitting grooves. Effects of the invention

[0021] According to the present invention, since the busbar can be naturally and selectively inserted or removed from the protrusion of the connector housing, there is an effect of being able to replace a busbar of various shapes with a busbar of a different shape suitable for the layout according to the design layout.

[0022] As a result, the present invention has the effect of making the connector housing and the busbar compatible with the requirements of the design layout. Brief explanation of the drawing

[0029] FIG. 1 is a perspective view showing a connector assembly according to an embodiment of the present invention, FIG. 2 is a perspective view showing the other direction of a connector assembly according to an embodiment of the present invention, FIG. 3 is a perspective view showing a connector housing and a bus bar of a connector assembly according to an embodiment of the present invention, and FIG. 4 is an exploded perspective view showing the disassembled state of a connector assembly according to an embodiment of the present invention.

[0030] Referring to FIGS. 1 to 4, a connector assembly according to an embodiment of the present invention, which is composed of a male connector, includes a connector housing (100), a connector block (200), a bus bar (300), a protective part (400), and a fixing part (500).

[0031] The connector housing (100) accommodates multiple terminals inside, and a connector housing (100) consisting of a female connector, which is a counterpart connector, can be inserted inside.

[0032] Here, the width of the connector housing (100) is formed wider than the connector housing (100) of the female connector so that the connector housing (100) of the female connector can be inserted.

[0033] The connector housing (100) includes a body portion (110), a protrusion (120), and a flange portion (130).

[0034] The body portion (110) forms the body of the connector housing (100), and preferably, the cross-sectional shape is generally elliptical.

[0035] And, as described above, a plurality of terminals are accommodated inside the body part (110).

[0036] The protrusion (120) protrudes from the rear of the body part (110), into which the bus bar (300) is inserted.

[0037] Accordingly, an insertion groove (121) is formed in this protrusion (120).

[0038] Meanwhile, the bus bar (300) is inserted or removed selectively from the rear of the connector housing (100) by penetrating the connector block (200), is made of a conductor, and is electrically connected to a terminal housed inside the body part (110).

[0039] Additionally, the bus bar (300) penetrates the connector block (200) and is inserted into a protrusion (120) formed on the rear of the connector housing (100), and is electrically connected to a plurality of terminals.

[0040] The insertion groove (121) communicates with the interior of the body part (110), and the bus bar (300) is selectively inserted or removed.

[0041] Accordingly, the bus bar (300) inserted through the insertion groove (121) can be electrically connected to the terminal received inside the body part (110).

[0042] Meanwhile, the bus bar (300) inserted into the insertion groove (121) can be naturally and selectively inserted or removed from the protrusion (120) of the connector housing (100) without a separate fixing part (500) or coupling component. More specifically, the bus bar (300) is inserted or removed from the insertion groove (121) in a sliding manner along the front-rear direction, and the surface inserted into the insertion groove (121) can be formed parallel to the front-rear direction.

[0043] That is, in the present invention, the bus bar (300) can be easily attached and detached from the connector housing (100).

[0044] Accordingly, in the present invention, a bus bar (300) made of various shapes can be replaced with a bus bar (300) made of a different shape that fits the layout according to the design layout.

[0045] As a result, the present invention can make the connector housing (100) and the busbar (300) compatible with the requirements of the design layout.

[0046] The flange portion (130) extends in a band shape along the circumference of the outer surface between the body portion (110) and the protrusion (120).

[0047] These flange portions (130) prevent the female connector from being excessively inserted when the female connector is connected to the connector housing (100).

[0048] Additionally, the flange portion (130) limits the connector block (200), which is positioned on the rear of the connector housing (100), from moving excessively in a straight direction while inserted into the connector housing (100).

[0049] The connector block (200) is positioned on the rear side of the connector housing (100) so that the bus bar (300) and the protection part (400) can be coupled to the connector housing (100).

[0050] A through hole (210), a guide portion (220), and a coupling portion (230) are formed in this connector block (200).

[0051] The through hole (210) is a hole through which the protrusion (120) passes, and it is preferable that it be formed in the center of the connector block (200).

[0052] Additionally, the through hole (210) is formed in a shape corresponding to the protrusion (120) by passing through the protrusion (120), and is formed with a size larger than the cross-sectional area of ​​the protrusion (120).

[0053] As a result, the protrusion (120) can be easily passed through the through hole (210).

[0054] The guide portion (220) extends from the through hole (210) at the rear of the connector block (200) in the direction in which the protective portion (400) is positioned.

[0055] And, the guide part (220) guides the coupling direction in which the protection part (400) is coupled to the connector block (200).

[0056] This guide section (220) can increase work efficiency by preventing misassembly of the connector block (200) and the protection section (400) during the process of assembling the protection section (400) to the connector block (200).

[0057] Meanwhile, a bus bar (300) is positioned on the upper part of the guide section (220).

[0058] That is, when the electrical device is connected to the bus bar (300), assembly pressure is generated from the top downward.

[0059] Accordingly, the guide portion (220) can firmly support the assembly pressure generated when the bus bar (300) and the electrical device are bolted together.

[0060] The connecting portion (230) is formed on the rear side of the connector block (200), and a separate bolt is fastened so that the protective portion (400) is connected.

[0061] That is, in the present invention, the connector block (200) is coupled to the flange portion (130) of the connector housing (100), and the protective portion (400) is coupled to the connector block (200).

[0062] As a result, the protective part (400) can firmly support the bus bar (300) inserted into the protrusion (120) of the connector housing (100).

[0063] The protective part (400) is coupled to the rear surface of the connector block (200) with the upper surface of the bus bar (300) inserted into the protrusion (120) of the connector housing (100) exposed.

[0064] This protective part (400) allows the bus bar (300) and the electrical device to be easily connected, while also effectively protecting the bus bar (300) from external forces.

[0065] Meanwhile, it is obvious that a coupling groove (410) into which a bus bar (300) can be inserted is formed in the protective part (400).

[0066] The fixed part (500) is coupled to the rear of the protective part (400) to seal the rear of the bus bar (300).

[0067] Specifically, on both sides of the protective part (400), fitting protrusions (420) protruding outward are formed.

[0068] And, a fitting groove (510) is formed in the fixed part (500) at a position corresponding to the fitting projection (420).

[0069] Accordingly, the fixed part (500) can be joined to the protective part (400) by means of the fitting projection (420) of the protective part (400) and the fitting groove (510) of the fixed part (500) in a fitting manner.

[0070] As a result, the fixing part (500) is detachably fitted to the protective part (400) fixed to the flange part (130) of the connector housing (100) via the connector block (200), thereby effectively preventing the bus bar (300) inserted into the protrusion (120) of the connector housing (100) from being removed from the insertion part. More specifically, the fixing part (500) is provided at the rear end of the bus bar (300) with respect to the front-rear direction to fix the front-rear position of the bus bar (300).

[0071] As described above, the present invention allows the bus bar (300) of various shapes to be naturally and selectively inserted or removed from the protrusion (120) of the connector housing (100), thereby allowing the bus bar (300) of various shapes to be replaced with a bus bar (300) of a different shape that fits the layout according to the design layout.

[0072] As a result, the present invention can make the connector housing (100) and the busbar (300) compatible with the requirements of the design layout.

[0074] As such, the embodiments disclosed in this specification should be considered in an exemplary sense for the sake of explanation rather than in a limiting sense. The scope of the invention is defined by the claims, not by the foregoing description, and all variations within the equivalent scope should be interpreted as being included in the invention.
