Description

TECHNICAL FIELD

[0001] The application relates to the technical field of wire harness fixing, in particular to a wire passing plate, a battery pack and an electric equipment. BACKGROUND

[0002] As an important component of power and signal transmission, wire harness has wide application and development prospect in various fields. For example, in the field of batteries, wire harness is usually used for signal and power transmission in the interior of a battery.

[0003] In the related art, in order to enhance the tensile resistance and waterproofness, sealing glue is usually applied at the wire outlet position of the plate body to bond the wire and the plate body and prevent the wire from being separated from the plate body. For example, the output wire harness in a battery pack usually needs to pass through the shell of the battery pack to supply power to the electric equipment outside the battery pack, so that the part of the wire harness passing through the shell of the battery pack is sealed by using glue.

[0004] However, the sealing glue usually has low hardness, which results in poor tensile resistance of the wire harness. In addition, when the wire harness bears a large tensile force, the wire harness is easily separated from the plate body, which causes the wire harness and the plate body to be unable to be sealed. CONTENT OF THE INVENTION

[0005] The application provides a wire passing plate, a battery pack and an electric equipment to improve the tensile strength and sealing performance of the wire harness and the plate body.

[0009] The first bonding block is arranged in the sink to bond the sink and the wire harness.

[0010] Beneficial effects: By first sealing the wire harness and the buckle, the buckle engages with the snap-fit ​​hole on the plate, and the first adhesive block fills the groove, the wire harness is bonded to the groove. Thus, the wire harness and the plate are connected simultaneously by the snap-fit ​​force between the buckle and the plate and the adhesive force of the first adhesive block, thereby improving the tensile strength of the wire harness and ensuring the sealing performance between the wire harness and the plate.

[0013] In one optional embodiment, a plurality of receiving grooves are provided circumferentially on the outer peripheral surface of the buckle, the receiving grooves extending along the first direction, and an elastic tongue is formed in each receiving groove. The elastic tongue can elastically deform along the radial direction of the thread hole, and the elastic tongue is used to engage with the first side.

[0014] In one alternative embodiment, a flange is provided on the outer peripheral surface of the buckle at a location away from the elastic tongue between two adjacent receiving grooves.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] In related technologies, after the wire harness passes through the board, in order to enhance tensile strength and water resistance, sealant is usually applied to the wire exit point of the board to bond the cable to the board and prevent it from falling off. For example, the output wire harness in the battery pack usually needs to pass through the battery pack shell to supply power to the electrical equipment located outside the battery pack, which requires the part of the wire harness that passes through the battery pack shell to be sealed with glue.

[0036] However, sealant often has a low hardness, resulting in poor tensile strength of the wire harness. At the same time, when the wire harness is subjected to a large tensile force, it is easy for the wire harness to slip off from the board, making it impossible to seal the wire harness with the board. The "tensile strength" mentioned above refers to the performance of the wire harness relative to the board under tension, not the performance of the wire harness being easy to break.

[0037] The following is combined with Figures 1 to 5 This describes an embodiment of the present application.

[0038] According to embodiments of this application, in one aspect, a threading plate is provided, such as... Figure 1 As shown, the wiring board includes a plate body 1, a buckle 2, a wire harness 3, and a first adhesive block, and has a first direction X. The wiring board can be a cover plate with a wiring structure on the battery pack, or part of the battery casing, or part of any other device. The specific solution is as follows.

[0039] like Figure 1 As shown, the plate 1 has a first side surface 11 and a second side surface 12 disposed opposite to each other along the first direction X, as follows: Figure 2 As shown, a sink 13 is provided on the first side 11 along the first direction X. The cross-section of the inner wall surface of the sink 13 along the first direction X can be any other shape such as circle, triangle, square, ellipse, etc. A snap-fit ​​through hole 14 is provided on the inner surface of the sink 13 along the first direction X.

[0040] like Figure 1As shown, the buckle 2 is provided with a thread hole 21, and the buckle 2 is engaged with the snap-fit ​​hole 14. The snap-fit ​​hole 14 can restrict the buckle 2 from moving away from the first side 11. Specifically, the cross-section of the buckle 2 along the first direction X is polygonal, such as a triangle, a rectangle, or other arbitrary shapes.

[0041] Meanwhile, the cross-section of the snap-fit ​​hole 14 along the first direction X is the same as the cross-section of the buckle 2 along the first direction X, that is, the cross-section of the snap-fit ​​hole 14 along the first direction X matches the cross-section of the buckle 2 along the first direction X. For example, if the cross-section of the buckle 2 along the first direction X is square, then the cross-section of the snap-fit ​​hole 14 along the first direction X is square; or if the cross-section of the buckle 2 along the first direction X is pentagonal, then the cross-section of the snap-fit ​​hole 14 along the first direction X is pentagonal. As for the gap between the buckle 2 and the snap-fit ​​hole 14, it can be between 0.1mm and 0.5mm, preferably any one of 0.1mm, 0.2mm, 0.3mm, 0.4mm and 0.5mm, preferably 0.5mm.

[0042] like Figure 1 As shown, the wire hole 21 is used for the wire harness 3 to pass through and is sealed to the wire harness 3; that is, the wire harness 3 passes through the wire hole 21 and is sealed to the wire hole 21. Specifically, the wire hole 21 can be sealed to the wire harness 3 by interference fit, or by applying glue to the gap between the wire harness 3 and the wire hole 21 or to the end of the wire hole 21. Of course, other methods can also be used.

[0043] The first adhesive block is placed in the sink 13 to bond the sink 13 to the wire harness 3. Specifically, the first adhesive block can be a UV adhesive block or other types of structural adhesive blocks. The first adhesive block is usually formed by the curing of adhesive in the sink 13.

[0044] It should be noted that "adhesion" in the above refers to connection by means of adhesive.

[0045] In specific usage, such as Figure 1 As shown, taking a battery end cover in a battery pack as an example, the first direction X is perpendicular to the surface of the part of the battery end cover where the wire is threaded, and the groove 13 sinks from the outside of the battery end cover to the inside of the battery end cover.

[0046] First, such as Figure 1As shown, the buckle 2 is fitted onto the wire harness 3 through the wire hole 21. UV glue is sprayed onto the gap between the wire harness 3 and the wire hole 21 on the buckle 2, or onto the end of the wire hole 21, and then UV light is applied to accelerate the curing speed for rapid bonding. Then, the wire harness 3 and the buckle 2 are installed into the snap-fit ​​hole 14 from the inside to the outside of the battery end cover. The buckle 2 snaps into the snap-fit ​​hole 14 to prevent it from moving from the outside to the inside of the battery end cover. Finally, UV glue is injected into the sink 13 to form the first adhesive block, and then UV light is applied for rapid curing, thereby connecting the wire harness 3 to the battery end cover.

[0047] In this embodiment, such as Figure 1 As shown, by first sealing the wire harness 3 with the buckle 2, the buckle 2 is engaged with the snap-fit ​​hole 14 on the plate 1, and the first adhesive block is filled in the groove 13 to achieve the adhesion between the wire harness 3 and the groove 13. Thus, the wire harness 3 and the plate 1 are connected simultaneously by the snap-fit ​​force between the buckle 2 and the plate 1 and the adhesive force of the first adhesive block, thereby improving the tensile strength of the wire harness 3 and ensuring the sealing performance between the wire harness 3 and the plate 1.

[0048] In one embodiment, the wiring board further includes a second adhesive block. Specifically, the first adhesive block is a UV adhesive block, which can be a UV adhesive block or other types of structural adhesive blocks; such as... Figure 3 As shown, the wire hole 21 includes a first hole segment 211 and a second hole segment 212. The first hole segment 211 and the second hole segment 212 are connected. The cross-sectional area of ​​the first hole segment 211 along the first direction X is smaller than the cross-sectional area of ​​the second hole segment 212 along the first direction X. The second adhesive block is disposed in the second hole segment 212 to bond the wire bundle 3 to the second hole segment 212.

[0049] Specifically, the cross-section of the first hole segment 211 along the first direction X is usually a circle that matches the wire harness 3, but it can also be other shapes, as long as the wire harness 3 can pass through; the length of the first hole segment 211 along the first direction X is 1mm to 3mm, specifically any one of 1mm, 2mm and 3mm, preferably 3mm.

[0050] The cross-section of the second hole segment 212 along the first direction X is usually circular, but it can also be other shapes, such as square, ellipse or other shapes; the gap between the second hole segment 212 and the wire harness 3 is between 3mm and 5mm, specifically any one of 3mm, 4mm and 5mm; the length of the second hole segment 212 along the first direction X is between 3mm and 8mm, specifically any one of 3mm, 4mm, 5mm, 6mm, 7mm and 8mm.

[0051] It should be noted that the second adhesive block is usually formed by the curing of glue within the second hole section 212.

[0052] In this embodiment, such as Figure 3 As shown, by setting a first hole segment 211 and a second hole segment 212 in the wire hole 21, the first hole segment 211 is used to center the wire harness 3, and the second hole segment 212 is set at an interval from the wire harness 3. A second adhesive block is set in the second hole segment 212 to achieve the bonding between the wire harness 3 and the second hole segment 212, thereby enhancing the connection strength between the wire harness 3 and the buckle 2, and thus improving the tensile strength of the wire harness 3 relative to the plate 1.

[0053] In one embodiment, such as Figure 3 As shown, along the first direction X from the first side 11 to the second side 12, the first hole segment 211 and the second hole segment 212 are arranged in sequence, that is, the second adhesive block is located on one side of the first hole segment 211 along the first direction X, and the first adhesive block is located on the other side of the first hole segment 211 along the first direction X.

[0054] In this embodiment, such as Figure 3 As shown, by sequentially arranging the first hole segment 211 and the second hole along the first direction X from the first side 11 to the second side 12, the first adhesive block and the second adhesive block are respectively located on both sides of the first hole segment 211 along the first direction X. Thus, when the wire harness 3 is pulled from the first side 11 to the second side 12, the first adhesive block can provide greater tensile strength for the wire harness 3 under the constraint of the groove 13; while when the wire harness 3 is pulled from the second side 12 to the first side 11, the second adhesive block can provide greater tensile strength for the wire harness 3 under the constraint of the first hole segment 211, so that both sides of the wire harness 3 have greater tensile strength.

[0055] In some embodiments not shown, the first hole segment 211 and the second hole segment 212 are sequentially arranged along the first direction X from the second side 12 to the first side 11, that is, the second adhesive block and the first adhesive block are both located on the same side of the first hole segment 211 along the first direction X. In this embodiment, by sequentially arranging the first hole segment 211 and the second hole segment 212 along the first direction X from the second side 12 to the first side 11, when the wire harness 3 is pulled from the first side 11 to the second side 12, the first adhesive block and the second adhesive block are respectively restricted by the groove 13 and the first hole segment 211, and the wire harness 3 provides greater tensile strength, which can maximize the tensile performance of the wire harness 3 in the direction from the first side 11 to the second side 12. However, the tensile performance of the wire harness 3 in the direction from the second side 12 to the first side 11 is poor, which is suitable for situations where only one side is tensile.

[0056] In one embodiment, such as Figure 3As shown, a plurality of receiving grooves 22 are provided at circumferential intervals on the outer peripheral surface of the buckle 2. The receiving grooves 22 extend along the first direction X, and an elastic tongue 23 is formed in each receiving groove 22, such as... Figure 1 As shown, the elastic tongue 23 can elastically deform along the radial direction of the thread hole 21, and the elastic tongue 23 is engaged with the first side surface 11.

[0057] Specifically, the number of receiving slots 22 is 3 to 8. The specific number can be adjusted according to the size of the buckle 2 and the shape of the cross-section of the buckle 2 along the first direction X. For example, if the cross-section of the buckle 2 along the first direction X is square, then one receiving slot 22 or two receiving slots 22 are provided on each of the four sides.

[0058] In this embodiment, such as Figure 1 and Figure 3 As shown, by providing a receiving groove 22 on the outer peripheral surface of the buckle 2, and all receiving grooves 22 extending along the first direction X, and the elastic tongue 23 being provided in the receiving groove 22, the elastic tongue 23 can be made to overlap with the body of the buckle 2 along the first direction X, thereby reducing the length of the buckle 2 along the first direction X and improving the tightness of the fit between the buckle 2 and the plate 1.

[0059] In one embodiment, such as Figure 3 As shown, a flange 24 is provided on the outer peripheral surface of the buckle 2 at the part between two adjacent receiving grooves 22 away from the elastic tongue 23. The flange 24 abuts against the second side 12 to restrict the buckle 2 from moving towards the first side 11.

[0060] Specifically, the height of the flange 24 is 2mm to 5mm, specifically any one of 2mm, 3mm, 4mm and 5mm, with 3mm being the preferred height.

[0061] In this embodiment, such as Figure 3 As shown, a flange 24 is provided on the outer peripheral surface of the buckle 2 at a position away from the elastic tongue 23 between two adjacent receiving grooves 22 to abut against the second side 12, thereby restricting the buckle 2 from moving towards the first side 11. The flange 24 is not provided above the slide groove, which facilitates the demolding of the slide groove and the elastic tongue 23 during the molding process, making it easier to manufacture.

[0062] In one embodiment, such as Figure 4 As shown, the buckle 2 has a plurality of first reinforcing ribs 25 on the end face away from the second side 12 along the first direction X. The plurality of first reinforcing ribs 25 are arranged circumferentially at intervals along the wire hole 21. The plurality of first reinforcing ribs 25 all extend along the first direction X and are spaced apart from the wire harness 3.

[0063] Specifically, the number of first reinforcing ribs 25 is 3 to 5, or other numbers. In actual design, the number can be set according to the diameter of wire harness 3. The thickness of the reinforcing ribs along the circumference of wire harness 3 is 1mm to 3mm, specifically any one of 1mm, 2mm and 3mm.

[0064] In this embodiment, such as Figure 4 As shown, by providing multiple first reinforcing ribs 25 on the end face of the buckle 2 away from the second side 12 along the first direction X, the multiple first reinforcing ribs 25 are arranged circumferentially at intervals along the wire hole 21, and all the multiple first reinforcing ribs 25 extend along the first direction X. The multiple first reinforcing ribs 25 are all spaced apart from the wire harness 3, so that when glue is injected into the sink 13 to form the first adhesive block, the multiple first reinforcing ribs 25 can act as a skeleton in the first adhesive block to enhance the deformation resistance of the first adhesive block, thereby enhancing the connection strength between the first adhesive block and the sink 13 and the wire harness 3, thereby enhancing the tensile performance of the wire harness 3; at the same time, the extension of the first reinforcing ribs 25 along the first direction X facilitates demolding.

[0065] In one embodiment, such as Figure 5 As shown, a plurality of second reinforcing ribs 26 are formed on the wall surface of the second hole segment 212. The plurality of second reinforcing ribs 26 are arranged at intervals along the circumference of the second hole segment 212. The plurality of second reinforcing ribs 26 extend along the first direction X. The plurality of second reinforcing ribs 26 are spaced apart from the wire harness 3.

[0066] Specifically, the number of second reinforcing ribs 26 is 3 to 5, or other numbers, which can be set according to the size of the second hole in the actual design; the thickness of the second reinforcing ribs 26 along the circumference of the second hole segment 212 is 0.5mm to 2mm, specifically any one of 0.5mm, 1mm and 2mm.

[0067] In this embodiment, such as Figure 5 As shown, a plurality of second reinforcing ribs 26 are formed on the wall surface of the second hole segment 212. The plurality of second reinforcing ribs 26 are arranged at intervals along the circumference of the second hole segment 212 and extend along the first direction X. The plurality of second reinforcing ribs 26 are spaced apart from the wire harness 3. Thus, when glue is injected into the second hole segment 212 to form the second adhesive block, the plurality of second reinforcing ribs 26 can act as a skeleton in the second adhesive block to enhance the deformation resistance of the second adhesive block, thereby enhancing the connection strength between the second adhesive block and the second hole segment 212 and the wire harness 3, thereby enhancing the tensile performance of the wire harness 3. At the same time, the extension of the second reinforcing ribs 26 along the first direction X facilitates demolding.

[0068] The above solution will be fully described below with a complete embodiment.

[0069] This embodiment provides an embodiment according to this application, in which a threading board is provided, such as... Figure 1 As shown, the wiring board includes a plate body 1, a buckle 2, a wire harness 3, a first adhesive block and a second adhesive block, and has a first direction X. The wiring board can be a cover plate with a wiring structure on a battery pack, or part of the battery casing, or part of any other device. The specific solution is as follows.

[0070] like Figure 1 As shown, the plate 1 has a first side surface 11 and a second side surface 12 disposed opposite to each other along the first direction X, as follows: Figure 2 As shown, a sink 13 is provided on the first side 11 along the first direction X. The cross-section of the inner wall surface of the sink 13 along the first direction X can be any other shape such as circle, triangle, square, ellipse, etc. A snap-fit ​​through hole 14 is provided on the inner surface of the sink 13 along the first direction X.

[0071] like Figure 1 As shown, the buckle 2 is provided with a thread hole 21, and the buckle 2 is engaged with the snap-fit ​​hole 14. The snap-fit ​​hole 14 can restrict the buckle 2 from moving away from the first side 11. Specifically, the cross-section of the buckle 2 along the first direction X is polygonal, such as a triangle, a rectangle, or other arbitrary shapes.

[0072] Meanwhile, the cross-section of the snap-fit ​​hole 14 along the first direction X is the same as the cross-section of the buckle 2 along the first direction X, that is, the cross-section of the snap-fit ​​hole 14 along the first direction X matches the cross-section of the buckle 2 along the first direction X. For example, if the cross-section of the buckle 2 along the first direction X is square, then the cross-section of the snap-fit ​​hole 14 along the first direction X is square; or if the cross-section of the buckle 2 along the first direction X is pentagonal, then the cross-section of the snap-fit ​​hole 14 along the first direction X is pentagonal. As for the gap between the buckle 2 and the snap-fit ​​hole 14, it can be between 0.1mm and 0.5mm, preferably any one of 0.1mm, 0.2mm, 0.3mm, 0.4mm and 0.5mm, preferably 0.5mm.

[0073] like Figure 1 As shown, the wire hole 21 is used for the wire harness 3 to pass through and is sealed to the wire harness 3. That is, the wire harness 3 passes through the wire hole 21 and is sealed to the wire hole 21. Specifically, the wire hole 21 can be sealed to the wire harness 3 by interference fit, or by applying glue to the gap between the wire harness 3 and the wire hole 21 or to the end of the wire hole 21. Of course, other methods can also be used.

[0074] The first adhesive block is placed in the sink 13 to bond the sink 13 to the wire harness 3. Specifically, the first adhesive block can be a UV adhesive block or other types of structural adhesive blocks. The first adhesive block is usually formed by the curing of adhesive in the sink 13.

[0075] It should be noted that "adhesion" in the above refers to connection by means of adhesive.

[0076] like Figure 3 As shown, the wire hole 21 includes a first hole segment 211 and a second hole segment 212. The first hole segment 211 and the second hole segment 212 are connected. The cross-sectional area of ​​the first hole segment 211 along the first direction X is smaller than the cross-sectional area of ​​the second hole segment 212 along the first direction X. A second adhesive block is disposed in the second hole segment 212 to bond the wire bundle 3 to the second hole segment 212. The second adhesive block is a UV adhesive block. The first adhesive block can be a UV adhesive block or other types of structural adhesive blocks.

[0077] Specifically, the cross-section of the first hole segment 211 along the first direction X is usually a circle that matches the wire harness 3, but it can also be other shapes, as long as the wire harness 3 can pass through; the length of the first hole segment 211 along the first direction X is 1mm to 3mm, specifically any one of 1mm, 2mm and 3mm, preferably 3mm.

[0078] The cross-section of the second hole segment 212 along the first direction X is usually circular, but it can also be other shapes, such as square, ellipse or other shapes; the gap between the second hole segment 212 and the wire harness 3 is between 3mm and 5mm, specifically any one of 3mm, 4mm and 5mm; the length of the second hole segment 212 along the first direction X is between 3mm and 8mm, specifically any one of 3mm, 4mm, 5mm, 6mm, 7mm and 8mm.

[0079] It should be noted that the second adhesive block is usually formed by the curing of glue within the second hole section 212.

[0080] like Figure 3 As shown, along the first direction X from the first side 11 to the second side 12, the first hole segment 211 and the second hole segment 212 are arranged in sequence, that is, the second adhesive block is located on one side of the first hole segment 211 along the first direction X, and the first adhesive block is located on the other side of the first hole segment 211 along the first direction X.

[0081] like Figure 3 As shown, a plurality of receiving grooves 22 are provided at circumferential intervals on the outer peripheral surface of the buckle 2. The receiving grooves 22 extend along the first direction X, and an elastic tongue 23 is formed in each receiving groove 22, such as... Figure 1 As shown, the elastic tongue 23 can elastically deform along the radial direction of the thread hole 21, and the elastic tongue 23 is engaged with the first side surface 11.

[0082] Specifically, the number of receiving slots 22 is 3 to 8. The specific number can be adjusted according to the size of the buckle 2 and the shape of the cross-section of the buckle 2 along the first direction X. For example, if the cross-section of the buckle 2 along the first direction X is square, then one receiving slot 22 or two receiving slots 22 are provided on each of the four sides.

[0083] like Figure 3 As shown, a flange 24 is provided on the outer peripheral surface of the buckle 2 at the part between two adjacent receiving grooves 22 away from the elastic tongue 23. The flange 24 abuts against the second side 12 to restrict the buckle 2 from moving towards the first side 11.

[0084] Specifically, the height of the flange 24 is 2mm to 5mm, specifically any one of 2mm, 3mm, 4mm and 5mm, with 3mm being the preferred height.

[0085] like Figure 4 As shown, the buckle 2 has a plurality of first reinforcing ribs 25 on the end face away from the second side 12 along the first direction X.
