Description

Technology Field

[0001] The present invention relates to a grounding device for a vehicle, and more specifically, to a grounding device for a vehicle capable of grounding electrical components without damaging the grounding terminal. Background Technology

[0003] Unless otherwise indicated in this specification, the contents described in this identification item are not prior art for the claims of this application, and are not recognized as prior art simply because they are described in this identification item.

[0004] Generally, the interior of a vehicle is equipped with various components and drive systems (hereinafter referred to as "electrical components") that operate by receiving power from a battery. In order for power from the battery to be supplied to the electrical components, the components are connected to the battery's (+) terminal via wiring and grounded to the vehicle body. At this time, since the battery's (-) terminal is also connected to the vehicle body, when an electrical component is grounded to the vehicle body, it becomes equivalent to being connected to the battery's (-) terminal.

[0005] As illustrated in FIG. 1, the conventional technology for grounding electrical components to the vehicle body is structured such that the earth terminal (30) and the battery ground terminal (20) are directly connected to the binding bolt (40) and grounded to the vehicle body. In this case, the binding bolt (40) comes into direct contact with the earth terminal (30) and the battery ground terminal (20) and presses against the earth terminal (30) and the battery ground terminal (20). That is, the binding bolt (40) applies external force to the earth terminal (30) and the battery ground terminal (20), and accordingly, the earth terminal (30) and the battery ground terminal (20) may be deformed or damaged during the grounding process. Furthermore, if the degree of deformation or damage to the earth terminal (30) and the battery ground terminal (20) is severe, it may cause a problem in which the grounding state between the electrical components and the battery is released.

[0006] Therefore, there is a need for a vehicle grounding device that can stably ground electrical components and the battery without the terminal grounding the vehicle body being deformed or damaged. Prior art literature

[0009] The present invention has been devised to solve the above-mentioned problems and aims to provide a vehicle grounding device in which the grounding terminal for grounding electrical components and the battery is not deformed or damaged. means of solving the problem

[0011] To solve the above-mentioned problems, the present invention provides, as an embodiment of the present invention, a vehicle grounding device comprising: a housing including an open receiving space, an insertion part formed on a side, and a coupling part having a hollow formed protruding from the bottom surface and communicating with the outside; a socket part fixed by being coupled to the coupling part and having a hollow formed inside; a band strap part formed on the outer circumference of the socket part and including a strap member; a socket-type band strap that is received in the receiving space; a conductive rotating body provided between the socket part and the band strap part and rotatably engaged with the strap member; a conductive fastening member inserted into the hollow of the socket part, engaged with the conductive rotating body and coupled to the vehicle body, and received in the receiving space; a terminal body part coupled to a ground wire; a terminal contact part extending from the terminal body part and contacting the conductive rotating body as it is wound around and tightened on the strap member; a grounding terminal received in the receiving space through the insertion part; and a cover that covers the receiving space and is coupled to the housing.

[0012] Additionally, the cover has a through hole formed through which the conductive fastening member passes, and the conductive fastening member includes a head portion having a diameter larger than the diameter of the through hole and a screw portion extending from the head portion and engaging with the conductive rotating body and coupled to the vehicle body, and the socket portion has a first socket flange protruding from the outer surface of one end having a diameter larger than the hollow of the coupling portion and a locking anchor protruding from the outer surface of the other end, and the socket portion may be formed with a length smaller than the depth of the receiving space so that the first socket flange is located inside the receiving space.

[0013] Additionally, the cover has a through hole formed through which the socket portion passes, and the conductive fastening member includes a head portion having a diameter larger than the diameter of the through hole and a screw portion extending from the head portion and engaging with the conductive rotating body and coupled to the vehicle body, and the socket portion has a second socket flange protruding from the outer circumference of one end having a diameter larger than the diameter of the through hole, wherein the second socket flange can be pressed by the head portion from outside the receiving space.

[0014] In addition, the above cover may be formed of a transparent material.

[0015] Additionally, the socket portion has an outer diameter smaller than the diameter of the hollow of the coupling portion to be inserted into the coupling portion, and includes a rotation-prevention rail formed protruding longitudinally on the outer surface, and the coupling portion may have a rotation-prevention groove formed longitudinally on the inner surface of the hollow that corresponds to the rotation-prevention rail.

[0016] In addition, the above-mentioned anti-rotation rails may be formed in multiple numbers spaced apart in the circumferential direction, and the above-mentioned anti-rotation grooves may be formed in the same number as the above-mentioned anti-rotation rails spaced apart in the circumferential direction.

[0017] In addition, the housing includes a locking projection formed protruding from the outer side, and the cover may have a locking groove formed to be coupled with the locking projection corresponding to the locking projection. Effects of the invention

[0019] According to the means for solving the problem of the present invention as described above, various effects including the following can be expected. However, the present invention is not required to exhibit all of the following effects to be valid.

[0020] First, it has the effect of stably grounding the electrical components and the battery without the grounding terminal being deformed or damaged by the fastening member.

[0021] In addition, since the part of the grounding terminal that is grounded by the housing is not exposed to the outside, it is protected from external impacts, moisture, and foreign substances, and has the effect of enhancing the aesthetic appearance.

[0022] In addition, since it is simply joined by a strap member, it has the effect of improving assembly ease.

[0023] In addition, the transparent cover allows the assembly status to be easily checked visually from the outside, thereby improving ease of assembly.

[0024] In addition, the socket-type band strap and the conductive fastening member are prevented from rotating freely by means of the anti-rotation rail of the socket part and the anti-rotation groove of the coupling part, thereby enabling the grounding terminal to be wrapped around and tightened on the strap member.

[0025] In addition, due to the simple and excellent bonding structure of the housing and cover, the assembly and bonding strength of the housing and cover are improved. Brief explanation of the drawing

[0030] As illustrated in these drawings, the vehicle grounding device (100) according to the present invention grounds a battery and electrical components mounted in a vehicle and comprises: a housing (1000) including an open receiving space (1100), an insertion part (1200) formed on the side, and a coupling part (1300) having a hollow formed protruding from the bottom surface and communicating with the outside; a socket part (2100) fixed by being coupled to the coupling part (1300) and having a hollow formed inside; a band strap part (2200) formed on the outer surface of the socket part (2100) and including a strap member (2210); a socket-type band strap (2000) received in the receiving space (1100); a conductive rotating body (3000) provided between the socket part (2100) and the band strap part (2200) and rotatable while engaging with the strap member (2210); and a conductive rotating body inserted into the hollow of the socket part (2100). It includes a conductive fastening member (4000) that engages with a rotating body (3000) and is coupled to a vehicle body and is received in a receiving space (1100), a terminal body part (5100) that is coupled to a ground wire, a terminal contact part (5200) that is extended from the terminal body part (5100) and contacts the conductive rotating body (3000) as it is wound around and tightened by a strap member (2210), a ground terminal (5000) that is received in the receiving space (1100) through an insertion part (1200), and a cover (6000) that covers the receiving space (1100) and is coupled to a housing (1000).

[0031] The housing (1000) serves to accommodate other components of the present invention and protects against external impacts, moisture, foreign substances, etc., and may be manufactured from a plastic material. The housing (1000) may be manufactured from a transparent plastic material together with the cover (6000) made of a transparent material, which will be described later. Additionally, a locking projection (1400) may be formed protrudingly on the outer side of the housing (1000). The locking projection (1400) may be coupled with the locking groove (6200) of the cover (6000), which will be described later. The locking projection (1400) may be formed in multiple numbers, and the multiple locking projections (1400) may be coupled with the multiple locking grooves (6200) to increase the coupling force between the housing (1000) and the cover (6000).

[0032] The receiving space (1100) is formed by a plurality of inner surfaces of the housing (1000). The receiving space (1100) can accommodate a socket-type band strap (2000), a conductive rotating body (3000), a conductive fastening member (4000), and a grounding terminal (5000). Among the plurality of inner surfaces forming the receiving space (1100), a portion of the side is cut to form an insertion part (1200). The insertion part (1200) communicates with the outside. Through this insertion part (1200), the grounding terminal (5000) can be inserted into the receiving space (1100) and accommodated. Among the plurality of inner surfaces forming the receiving space (1100), a coupling part (1300) is formed protruding from the bottom surface. It is preferable that the coupling part (1300) be formed in a hollow cylindrical shape. The socket portion (2100) of the socket-type band strap (2000) can be inserted into the hollow of the coupling portion (1300) and coupled with each other. When the socket-type band strap (2000) is inserted into the hollow of the coupling portion (1300) and coupled, one side of the coupling portion (1300) may be partially cut to form an incision (1320) on which the band strap portion (2200) is mounted. Additionally, the coupling portion (1300) may have a rotation-prevention groove (1310) formed longitudinally on the inner surface of the hollow. The rotation-prevention groove (1310) may be coupled with the rotation-prevention rail (2150) of the socket portion (2100), which will be described later, to fix the socket portion (2100) so that it does not rotate relative to the coupling portion (1300). The rotation-prevention groove (1310) may be spaced out in the circumferential direction and formed in the same number as the rotation-prevention rail (2150).

[0033] A socket-type band strap (2000) coupled to a coupling portion (1300) of a housing (1000) serves to electrically connect a conductive rotating body (3000) and a conductive fastening member (4000), and may be manufactured from an elastic plastic material. The elastic socket-type band strap (2000) can be easily inserted into the hollow of the coupling portion (1300). The socket-type band strap (2000) includes a socket portion (2100) that is coupled to and fixed to the coupling portion (1300) and has a hollow formed inside, and a band strap portion (2200) formed on the outer surface of the socket portion (2100) and including a strap member (2210).

[0034] The socket portion (2100) coupled to the coupling portion (1300) of the housing (1000) can be manufactured from an elastic plastic material in a shape that is easily inserted into the hollow of the coupling portion (1300). When the coupling portion (1300) is formed in a cylindrical shape, it is preferable to form it in a cylindrical shape having an outer diameter that is slightly smaller than the diameter of the hollow of the coupling portion (1300). Additionally, since a conductive fastening member (4000) is inserted into the hollow of the socket portion (2100), it is preferable for the socket portion (2100) to be formed in a cylindrical shape to facilitate the insertion of the conductive fastening member (4000). The socket portion (2100) is inserted into and coupled to the hollow of the coupling portion (1300), and the socket portion (2100) can be fixed without rotating relative to the coupling portion (1300) due to the frictional force between the outer surface of the socket portion (2100) and the inner surface of the hollow of the coupling portion (1300). Additionally, as illustrated in FIG. 7, the socket portion (2100) may include a rotation-prevention rail (2150) formed protruding longitudinally on the outer surface. The rotation-prevention rail (2150) may be coupled with the rotation-prevention groove (1310) of the aforementioned coupling portion (1300). Multiple rotation-prevention rails (2150) may be formed on the outer surface of the socket portion (2100) at circumferential intervals. Multiple rotation-prevention rails (2150) can further enhance the effect of preventing the socket portion (2100) from rotating on the coupling portion (1300).

[0035] Additionally, as illustrated in FIG. 4, the socket portion (2100) may have a first socket flange (2110) protruding from one end of the outer surface, having a diameter larger than the hollow of the coupling portion (1300), and a catch anchor (2130) protruding from the outer surface of the other end. The first socket flange (2110) catches on the open portion on one side of the hollow of the coupling portion (1300), thereby preventing the socket portion (2100) from detaching from the coupling portion (1300). The catch anchor (2130) catches on the open portion on the other side of the hollow of the coupling portion (1300), thereby preventing the socket portion (2100) from detaching from the coupling portion (1300). That is, the first socket flange (2110) and the locking anchor (2130) can prevent the socket portion (2100) from being dislodged in the longitudinal direction after being inserted into the hollow of the coupling portion (1300). In this case, the socket portion (2100) is formed with a length smaller than the depth of the receiving space (1100) so that the first socket flange (2110) is located inside the receiving space (1100).

[0036] Meanwhile, as illustrated in FIGS. 9 and 10, a second socket flange (2120) may be formed protruding from the outer surface of the socket portion (2100), having a diameter larger than that of the through hole (6100) to be described later. The second socket flange (2120) may be pressed by the head portion (4100) of the fastening member to be described later from outside the receiving space (1100). Unlike the first socket flange (2110) described above, the second socket flange (2120) is located outside the receiving space (1100) and can be pressed by the head portion (4100) of the fastening member to close the through hole (6100). As the second socket flange (2120) is in close contact with the upper surface of the cover (6000), the socket portion (2100) may not be detached from the coupling portion (1300).

[0037] A band strap portion (2200) formed on the outer surface of a socket portion (2100) serves to bring a ground terminal (5000) and a conductive rotating body (3000) into contact, and can be manufactured from an elastic plastic material. As shown in FIG. 5, the band strap portion (2200) includes a strap member (2210) that can wrap around and secure the ground terminal (5000). The band strap portion (2200) may include a strap body (2220) extending from the socket portion (2100) and a strap member (2210) extending from the strap body (2220). The strap body (2220) may have a seating groove (2221) into which a conductive rotating body (3000) is inserted and seated, a strap insertion hole (2222) in which a strap member (2210) is inserted and which communicates with the seating groove (2221), and a terminal contact hole (2223) in which the strap insertion hole (2222) communicates and which is oriented toward a ground terminal (5000).

[0038] The strap member (2210) can wrap around and tighten the ground terminal (5000) while passing through the strap insertion hole (2222) formed through the strap body (2220). The strap member (2210) may have a fixing hole (2211) formed continuously in the longitudinal direction. The fixing hole (2211) engages with the tooth of the gear of the conductive rotating body (3000), and accordingly, the strap member (2210) is tightened and wraps around and fixes the ground terminal (5000). Depending on the rotational direction of the conductive rotating body (3000), the strap member (2210) may wrap around or not wrap the ground terminal (5000), thereby allowing the ground terminal (5000) and the conductive rotating body (3000) to come into contact with each other or remain in contact. For example, when the conductive rotating body (3000) is rotated counterclockwise, the strap member (2210) can wrap around and tighten the grounding terminal (5000), causing the grounding terminal (5000) to come into contact with the conductive rotating body (3000). That is, as the strap member (2210) tightens, the grounding terminal (5000) comes into contact with the strap body (2220) and presses the strap body (2220), and the strap body (2220) undergoes elastic deformation, allowing the grounding terminal (5000) and the conductive rotating body (3000) to come into contact. The grounding terminal (5000) can come into contact with the conductive rotating body (3000) through the terminal contact hole (2223) and the strap insertion hole (2222).

[0039] Conversely, when the conductive rotating body (3000) rotates clockwise, the strap member (2210) is released from the ground terminal (5000), and the ground terminal (5000) and the conductive rotating body (3000) can be made non-contact. That is, as the strap member (2210) is released, the ground terminal (5000) moves away from the conductive rotating body (3000) and becomes non-contact due to the elastic recovery of the strap body.

[0040] A conductive rotating body (3000) provided between the socket portion (2100) and the band strap portion (2200) serves to electrically connect the ground terminal (5000) and the conductive fastening member (4000), and can be formed in the shape of a gear made of a conductive metal material. As shown in FIG. 6, the conductive rotating body (3000) can be inserted into and seated in the seating groove (2221) of the strap body (2220). The conductive rotating body (3000) has teeth formed on its outer surface, and the teeth can engage with the strap member (2210) and the conductive fastening member (4000). That is, the conductive rotating body (3000) engages with the longitudinal thread (4210) of the conductive fastening member (4000), which will be described later, and simultaneously engages with the fixing hole of the strap member (2210). As the conductive fastening member (4000) rotates, the conductive rotating body (3000) also rotates, and as the conductive rotating body (3000) rotates, the strap member (2210) is tightened or loosened. When the strap member (2210) is tightened, the grounding terminal (5000), the conductive rotating body (3000), and the conductive fastening member (4000) come into contact and are electrically connected, and when the strap member (2210) is loosened, the grounding terminal (5000), the conductive rotating body (3000), and the conductive fastening member (4000) come into non-contact and the electrical connection is released.

[0041] A conductive fastening member (4000) inserted into the hollow of the socket portion (2100) is connected to a grounding terminal (5000) and serves to ground the vehicle body by being coupled thereto, and can be formed in the shape of a bolt made of a conductive metal material. The conductive fastening member (4000) includes a head portion (4100) having a diameter larger than the diameter of the through hole (6100) to be described later, and a screw portion (4200) that is extended from the head portion (4100), engages with a conductive rotating body (3000), and is coupled to the vehicle body. The head portion (4100) can close the through hole (6100) by directly covering it or close the through hole (6100) by pressing the second socket flange (2120). The screw portion (4200) may include a longitudinal screw thread (4210) that engages with the conductive rotating body (3000) and a transverse screw thread (4220) that engages with the vehicle body. The longitudinal screw thread (4210) is a screw thread formed along the longitudinal direction of the screw portion (4200), and the transverse screw thread (4220) is a general screw thread formed along the circumferential direction of the screw portion (4200). As described above, the longitudinal screw thread (4210) engages with the teeth of the conductive rotating body (3000).

[0042] A grounding terminal (5000) that is received in a receiving space (1100) through an insertion part (1200) of a housing (1000) is connected to a grounding wire (C) and connected to a conductive fastening member (4000) to perform the function of grounding, and can be manufactured from a conductive metal material. The grounding terminal (5000) includes a terminal body part (5100) that is coupled to the grounding wire (C), and a terminal contact part (5200) that is extended from the terminal body part (5100) and contacts a conductive rotating body (3000) as it is wound around and tightened by a strap member (2210). The terminal body part (5100) is the part coupled to the grounding wire (C), and the terminal contact part (5200) is the part that is wound around the strap member (2210). It is preferable that the terminal contact part (5200) be formed in a cylindrical shape that can be wound by the strap member (2210). The terminal contact portion (5200) can be tightened or loosened by the strap member (2210) and may come into contact with or not come into contact with the conductive rotating body (3000).

[0043] The cover (6000) combined with the housing (1000) serves to close the receiving space (1100) of the housing (1000) and can be manufactured from a transparent plastic material. When the cover (6000) is manufactured from a transparent plastic material, assembly is possible by checking the inside of the receiving space (1100) of the housing (1000) from the outside, thus improving assembly efficiency.

[0044] A through hole (6100) may be formed in the cover (6000). A conductive fastening member (4000) or a socket portion (2100) of a socket-type band strap (2000) may pass through the through hole (6100). If the socket portion (2100) of the socket-type band strap (2000) is formed with a length smaller than the depth of the receiving space (1100), the through hole (6100) may be closed by the head portion (4100) of the conductive fastening member (4000). If a second socket flange (2120) is formed in the socket portion (2100) of the socket-type band strap (2000), the through hole (6100) may be closed by the second socket flange (2120).

[0045] Additionally, as described above, the cover (6000) may have a locking groove (6200) formed therein corresponding to the locking projection (1400) of the housing (1000). The locking groove (6200) is coupled with the locking projection (1400) to allow the housing (1000) and the cover (6000) to be coupled, and may be formed in multiple numbers equal to the number of the locking projection (1400).

[0046] Hereinafter, the process of installing a vehicle assembly device according to one embodiment of the present invention on a vehicle body will be briefly described.

[0047] As illustrated in FIG. 11, with the receiving space (1100) of the housing (1000) open, the terminal contact portion (5200) of the ground terminal (5000) is positioned adjacent to the coupling portion (1300) of the housing (1000). A socket-type band strap (2000) coupled with a conductive rotating body (3000) is inserted into the coupling portion (1300) of the housing (1000), at which time the strap member (2210) surrounds the terminal contact portion (5200). Then, a cover (6000) is coupled with the housing (1000) and closes the receiving space (1100) of the housing (1000). The conductive fastening member (4000) penetrates the through hole (6100) of the cover (6000) and the hollow of the socket portion (2100) of the socket-type band strap (2000), and the longitudinal thread (4210) of the conductive fastening member (4000) engages with the conductive rotating body (3000). The conductive fastening member (4000) rotates to engage with the conductive rotating body (3000) and is simultaneously coupled to the vehicle body. As the conductive fastening member (4000) rotates, the strap member (2210) engages with the teeth of the conductive rotating body (3000) and wraps around and secures the terminal contact portion (5200) of the ground terminal (5000), and the terminal contact portion (5200) of the ground terminal (5000) is secured by the strap member (2210) and comes into contact with the conductive rotating body (3000). Ultimately, the grounding terminal (5000), the conductive rotating body (3000), and the conductive fastening member (4000) are electrically connected.

[0048] As seen above, the vehicle grounding device (100) according to one embodiment of the present invention first has the effect of stably grounding the electrical components and the battery without the grounding terminal (5000) being deformed or damaged by the conductive fastening member (4000). In addition, since the part of the grounding terminal (5000) that is grounded by the housing (1000) is not exposed to the outside, it is protected from external impacts, moisture, and foreign substances, and the aesthetic appearance is enhanced. Furthermore, since it is simply connected by the strap member (2210), assembly is improved. In addition, due to the cover (6000) made of a transparent material, the assembly state can be easily checked visually from the outside, thereby improving assembly. In addition, the socket-type band strap (2000) and the conductive fastening member (4000) do not rotate freely due to the anti-rotation rail (2150) of the socket part (2100) and the anti-rotation groove (1310) of the coupling part (1300), thereby allowing the grounding terminal (5000) to be wrapped around and tightened on the strap member (2210). Furthermore, due to the simple and excellent coupling structure of the housing (1000) and the cover (6000), the assembly and coupling strength of the housing (1000) and the cover (6000) are improved.
