Description

Technology Field

[0001] The present invention relates to a connector unit, and more specifically, to a connector unit that relays an electrical connection by coupling. Background Technology

[0002] Vehicles use numerous connectors to supply power to various electronic components or to make electrical connections between them; recently, as many functions are added as options to enhance passenger convenience, more connectors are being installed within limited spaces.

[0003] Furthermore, with the recent proliferation of electric vehicles, high-voltage connectors are being widely used due to the occurrence of electrical connections via high-voltage power sources. In this context, it is common practice to install shielding materials on connectors to eliminate noise generated by electrical connections, thereby ensuring that numerous electronic components function stably.

[0004] However, a problem occurred in which the shielding performance deteriorated as the contact portion of the shielding member, which serves as the noise emission path, became detached due to vibrations and external forces generated during vehicle operation. Additionally, even when some contact portions remained in contact, the shielding performance deteriorated as resistance increased due to a reduction in the contact area. The problem to be solved

[0005] One embodiment of the present invention is devised to solve the above-mentioned problems and aims to provide a connector unit that provides a stable shielding function. means of solving the problem

[0006] A connector unit of one embodiment of the present invention comprises: a connector portion formed of first and second connectors electrically connected by coupling; a shielding portion formed on the inner side of the connector portion to eliminate noise generated by the electrical connection; and a pressure member penetrating the connector portion and providing pressure to the shielding portion; wherein the shielding portion is formed of a first shielding member formed on the inner side of the first connector and a second shielding member formed on the outer side of the second connector, such that the second shielding member is received on the inner side of the first shielding member by coupling of the first and second connectors, and the first shielding member is in close contact with the second shielding member by the pressure generated by the pressure member.

[0007] The above-mentioned pressure member is positioned outside the first shielding member through an opening formed in the first connector, moved to a preset position, fixed, and can generate a pressure.

[0008] The above-mentioned pressure member is formed with a pressure body inserted into the opening and positioned outside the first shielding member, and first and second pressure protrusions protruding at regular intervals outside the pressure body, wherein the first pressure protrusion is fixed and secured inside the first connector, and as the second pressure protrusion is fixed and secured inside the first connector by movement, a pressure force can be generated outside the first shielding member.

[0009] The above opening is formed with an opening hole having a shape that accommodates both the pressure body and the first and second pressure protrusions, and an interference protrusion that supports one side of the first and second pressure protrusions around the opening hole, thereby limiting the range of movement of the first and second pressure protrusions and preventing the release of the fixing force.

[0010] The shielding member may further have a first expansion structure formed on the inner surface of the first shielding member and a second expansion structure formed on the outer surface of the second shielding member that is complementarily coupled to the first expansion structure, thereby increasing the contact area when the first and second shielding members are in close contact by the pressurizing member.

[0011] One of the first expansion structure and the second expansion structure may be formed as a curved groove that is recessed and formed concavely, and the other may be formed as a curved projection that is protruded and formed convexly. Effects of the invention

[0012] As examined above, various effects including the following can be expected according to the means for solving the problem of the present invention. However, the present invention is not required to exhibit all of the following effects to be valid.

[0013] The connector unit of the present invention is provided with a pressurizing member that pressurizes a shielding part contacted by the coupling of the connector part, thereby preventing the noise discharge path for shielding from being arbitrarily disconnected.

[0014] In addition, the first and second shielding members constituting the shielding section form first and second expansion structures that are complementarily coupled to each other, thereby expanding the contact area and preventing an increase in resistance during noise emission, thus providing high shielding performance.

[0015] At this time, a structure that does not generate pressure when the first and second connectors are connected is disclosed to prevent an increase in insertion force, thereby preventing an increase in worker fatigue and providing the effect of improving product productivity.

[0016] In addition, the pressure member is formed with a structure that is temporarily fixed to one side of the first connector before the first and second connectors are joined, thereby preventing loss during operation and improving workability, thereby maximizing the effect of improving product productivity.

[0019] For the convenience of explanation, the direction in which the first and second connectors are joined is defined as the joining direction, the direction in which the pressing member moves is defined as the pressing direction, and the direction perpendicularly intersecting the joining direction and the pressing direction is defined as the intersecting direction.

[0021] However, the above definition of direction is for the convenience of the invention of the following embodiment, and the direction may differ when applied to an actual connector; even if the direction is different, configurations that provide the same function and effect may fall within the scope of the present invention.

[0023] FIG. 1 is a perspective view of a connector unit of one embodiment of the present invention, FIG. 2 is an exploded perspective view of FIG. 1, FIG. 3 is a cross-sectional view in the direction III-III of FIG. 1, FIG. 4 is an enlarged view of part A of FIG. 3, FIG. 5 is a drawing illustrating a method in which a pressing member in FIG. 4 generates a pressing force, and FIG. 6 is a drawing in which the shielding part of FIG. 2 is applied with a first and second expansion structure of another example.

[0024] Referring to FIGS. 1 to 6, a connector unit (10) of an embodiment of the present invention comprises a connector portion (100) formed by first and second connectors (110, 120) that are electrically connected by coupling, a shielding portion (200) formed inside the connector portion (100) to remove noise generated by the electrical connection, and a pressure member (300) that penetrates the connector portion (100) and provides pressure to the shielding portion (200). The shielding portion (200) is formed by a first shielding member (210) formed inside the first connector (110) and a second shielding member (220) formed outside the second connector (120), wherein the first and second connectors (110, 120) are coupled to the inside of the first shielding member (210). A second shielding member (220) is accommodated, and the first shielding member (210) is in close contact with the second shielding member (220) by the pressure generated by the pressure member (300), thereby providing a stable shielding function.

[0025] The connector unit (10) relays an electrical connection through contact with a terminal (not shown) formed inwardly by the combination of the first and second connectors (110, 120), and accordingly performs various functions such as supplying power to electrical components and transmitting electrical signals.

[0026] To this end, the connector unit (10) is provided with a connector section (100) formed by first and second connectors (110, 120) that are coupled to each other. In addition, since noise generated by the electrical connection can interfere with functions such as power supply and electrical signal transmission, potentially leading to electrical connection stability and deterioration of component functionality, the unit is provided with a shielding section (200) that discharges noise.

[0027] Specifically, the connector portion (100) is formed with first and second connectors (110, 120) that are electrically connected by being joined in a joining direction. At this time, the first connector (110) is formed with a first connector body (111) that forms the exterior and a first connecting body (112) in which a terminal (not shown) is installed on the inside.

[0028] Accordingly, the first connector (110) has a receiving space (1111) formed between the first connector body (111) and the first connecting body (112) that is open to one side in the coupling direction, and a first communication space (1121) formed inside the second connecting body (122) that is open in the coupling direction.

[0029] Additionally, the second connector (120) is formed with a second connector body (121) forming the exterior and a second connecting body (122) having a terminal (not shown) installed on the inside, and a second communication space (1221) open in the direction of connection is formed on the inside of the second connecting body (122).

[0030] Accordingly, the connector part (100) receives the second connector body into the receiving space (1111) so that the first and second connectors (110, 120) are combined, and at this time, one of the first and second connecting bodies (112, 122) is received into the inner side of the other, and the first and second communication spaces (1121, 1221) are connected to generate an electrical connection.

[0031] At this time, the first connector (110) is formed with an opening (113) through which a pressure member (300) is installed by penetrating the first connector body (111), so that after the first and second connectors (110, 120) are combined, a worker can move the pressure member (300) from the outside of the first connector body (111).

[0032] To this end, the opening (113) is formed with an opening hole (1131) having a shape capable of accommodating both the pressure body (310) and the pressure projection (320), and an interference projection (1132) that protrudes from the periphery of the opening hole (1131) and supports one side of the pressure projection (320).

[0033] Accordingly, the pressure member (300) is inserted into the open hole (1131) according to its shape and then rotated, and one of the pressure protrusions (320) is supported on the inner surface of the first connector body (111) and fixed in place.

[0034] At this time, on one side of the first connector body (111) in which the opening hole (1131) is formed, an interference projection (1132) protruding in the direction of pressure is further formed around the opening hole (1131) through which the pressure projection (320) passes, thereby limiting the range of movement of the pressure member (300).

[0035] Therefore, this prevents the pressure member (300) from rotating excessively and re-escaping into the open hole (1131), and improves workability by allowing the worker to intuitively recognize the movement state of the pressure member (300).

[0036] The shielding portion (200) is formed by a first shielding member (210) installed inside the first connector (110) and a second shielding member (220) installed outside the second connector (120), and the second shielding member (220) is positioned inside the first shielding member (210) in the receiving space (1111) by the combination of the first and second connectors (110, 120).

[0037] Accordingly, the shielding part (200) is positioned to surround the outer perimeter of the first and second connection bodies (112, 122) where electrical connections occur, thereby effectively discharging the generated noise to the outside.

[0038] To this end, the first shielding member (210) is formed as a first shielding body (211) installed along the inner circumference of the first connector body (111), and the second shielding member (220) is formed as a second shielding body (221) installed along the outer circumference of the second connector body (121).

[0039] At this time, a first expansion structure (212) is formed in the first shielding body (211), and a second expansion structure (222) that is complementarily coupled to the first expansion structure (212) is formed in the second shielding body (221) to expand the contact area and prevent the resistance from increasing when noise is discharged.

[0040] Specifically, in one example, the first expansion structure (212) is formed as a concave curved groove so as to be recessed in a direction opposite to the second shielding member (220), and the second expansion structure (222) is formed as a convex curved projection so as to protrude in a direction opposite to the first shielding member (210).

[0041] Here, the curved grooves and curved protrusions are formed to have the same pattern on the entire surface or a part of the first and second shielding bodies, so that when the first and second connectors (110, 120) are fully coupled, the curved protrusions are seated in each curved groove, thereby increasing the contact area.

[0042] However, the above-mentioned first and second expansion structures (212, 222) are examples, and since interference by the first and second expansion structures (212, 222) does not occur to the extent that it hinders the insertion of the first and second connectors (110, 120) before the pressure of the pressure member (300) is generated, the first and second expansion structures (212, 222) can be formed in various structures that are complementarily coupled to each other.

[0043] In addition, both the first and second extension structures (212, 222) may be formed by mixing curved grooves and curved protrusions, but when the first and second connectors (110, 120) are combined, they are formed in a pattern that can be combined complementarily with each other.

[0044] To examine this in detail, as shown in FIG. 2, the first and second extension structures (212, 222) of one example are formed in a grid in the joining direction and the intersecting direction, and each first and second extension structure (212, 222) has a structure in which they are arranged in a line.

[0045] Also, as shown in FIG. 6, the first and second extension structures (212, 222) of another example are arranged in a line in the cross direction, but the different first and second extension structures (212, 222) adjacent to each other in the joining direction are not arranged on the same line.

[0046] In other words, the first and second extension structures (212, 222) have the same contact area as the first and second extension structures (212, 222) of the example to ensure shielding performance, but prevent each first extension structure (212) and each second extension structure (222) from being fully seated during the insertion process.

[0047] Accordingly, interference caused by the first and second extension structures (212, 222) being seated during the process of combining and separating the first and second connectors (110, 120) can be minimized, thereby improving workability and product durability.

[0048] To maximize the above-mentioned effect, it is preferable that the first and second extension structures (212, 222) be formed in a line in either the joining direction or the intersecting direction, but not arranged in a line in the other direction.

[0049] Accordingly, the connector unit (10) of the present invention secures electrical connection stability by having a shielding part (200) that comes into contact with each other to form a noise discharge path when the first and second connectors (110, 120) are combined, i.e., electrically connected.

[0050] In addition, the shielding part (200) is equipped with first and second expansion structures (212, 222) that increase the contact area, thereby ensuring more stable shielding performance.

[0051] The pressure member (300) is installed by penetrating the first connector body (111) through an opening (113) formed in the first connector (110), and is formed with a structure that allows movement in the pressure direction at a specific location, so that after the first and second connectors (110, 120) are combined, it moves forward in the pressure direction and provides pressure to the shielding part (200).

[0052] To this end, the pressure member (300) is formed with a pressure body (310) extended in the direction of pressure and a pressure projection (320) protruding from one side of the pressure body (310) to provide fixing force, so that the pressure projection (320) is fixed by being caught in the receiving space (1111) through the open hole (1131).

[0053] At this time, it is preferable to further form an extension body (330) that extends to the other end of the pressure body (310), that is, the rear end in the pressure direction, and is fixed by being caught on the outer surface of the first connector body (111), thereby restricting the forward movement of the pressure member (300) in the pressure direction.

[0054] Specifically, in one example, the pressure member (300) is formed with a pressure projection (320) protruding from one side of the pressure body (310), which is formed with a first pressure projection (321) and a second pressure projection (322) spaced apart by a predetermined distance in the pressure direction, thereby temporarily fixing the pressure member (300) to the first connector (110) in the initial position, while simultaneously providing a pressure force forward in the pressure direction to the shielding part (200) in the moving position.

[0055] Here, the initial position is such that a part of the pressure body (310) and the first pressure projection (321) are positioned in the receiving space (1111) through the pressure hole, and at this time, the second pressure projection (322) is positioned on the outside of the first connector body (111).

[0056] Accordingly, when the pressure member (300) rotates at a predetermined angle around the pressure body (310), the first pressure projection (321) is supported on the inner surface of the first connector body (111), and the second pressure projection (322) is supported on the outer surface of the first connector body (111) and fixed.

[0057] However, in the initial position, one end of the pressure body (310) does not come into contact with the first shielding member (210), or even if it does come into contact, it does not generate pressure, thereby preventing the first and second shielding members (210, 220) from being excessively close and increasing the insertion force when the first and second connectors (110, 120) are connected.

[0058] The moving position is such that the pressure member (300) is rotated back to a predetermined angle from the initial position so that the shape of the open hole (1131) and the pressure member (300) match, and then the pressure member (300) is moved forward in the pressure direction and positioned in the receiving space (1111) up to the second pressure projection (322).

[0059] Accordingly, a pressure is applied forward in the direction of pressure from the outer side of the shielding part (200), that is, the first shielding member (210), so that the entire surface area of ​​the first and second shielding members (210, 220) is in close contact.

[0060] At this time, the operator rotates the pressure member (300) at a predetermined angle from the moving position so that the second pressure projection (322) is supported on the inner surface of the first connector body (111) to fix the pressure member (300), and the extension body (330) is supported on the outer surface of the first connector body (111) to provide a more stable pressure.

[0061] Here, the expansion body (330) has a shape and area capable of closing the entire area of ​​the open hole (1131), and a contact end (331) protruding in a pressure direction along the inner edge is further formed to seal the open hole (1131), i.e., the receiving space (1111).

[0062] In addition, it is preferable that the first and second pressure protrusions (320) rotate and move to a position supported on one side of the interference protrusion (1132) while the pressure member (300) is in a rotated state, that is, while a fixing force is generated with the first connector (110).

[0063] More preferably, the interference projection (1132) is formed in close proximity to the open hole (1131) to minimize the pressure member (300) moving in the opposite direction and detaching.

[0064] In summary, the connector unit (10) of the present invention provides the effect of improving product reliability by having a pressure member (300) that improves the contactability of a shielding part (200) that removes noise when the first and second connectors (110, 120) are combined, i.e., when an electrical connection is made.

[0065] At this time, the pressure member (300) is temporarily fixed to the first connector (110) in a state where it does not provide pressure in the initial position, thereby minimizing the possibility of loss during operation and improving the worker's workability.

[0066] In addition, during the coupling process of the first and second connectors (110, 120), no pressure is generated, thereby providing high contact of the shielding part (200) and preventing an increase in insertion force, which increases the effect of improving workability.

[0067] In addition, the contact area of ​​the shielding part (200) is secured above a certain level through the first and second expansion structures (212, 222), and the contact part of the shielding part (200) is prevented from detaching even under external forces such as vibrations generated during vehicle operation, thereby maximizing the effect of improving product reliability and durability.

[0068] Although preferred embodiments of the present invention have been described illustratively above, the scope of the present invention is not limited to such specific embodiments, and any modifications that are appropriately possible within the scope described in the claims fall within the scope of protection of the present invention.
