Description

Technical Field

[0001] The present invention relates to the technical field of wire fixing devices, and in particular to a wire pressing clamp, a vehicle air conditioner and a processing method of the wire pressing clamp. Background Art

[0002] The power cord of the electrical box of the indoor unit of the car air conditioner needs to be fixed relatively to the electrical box, and there are certain requirements for the fixing strength of the power cord. When the power cord is subjected to a certain value of pulling force, it is required that the power cord will not move relative to the electrical box as much as possible. At present, a wire clamp is generally fixed on the electrical box, and the power cord is compressed by the wire clamp to fix the power cord relatively to the electrical box. Considering that the car air conditioner is installed on the vehicle, there will be bumps and vibrations during the driving of the vehicle, which puts forward higher requirements for the fixing strength of the power cord.

[0003] The wire crimping clamp in the prior art includes a wire crimping seat and a wire crimping plate. The wire crimping seat has an integrally formed cylindrical portion and a U-shaped groove portion. The cylindrical portion is provided with an external thread for fixed connection with the electrical box. The power cord passes through the cylindrical portion and then through the U-shaped groove portion. The power cord can be fixed by using the wire crimping plate in cooperation with the U-shaped groove portion. In order to increase the fixing force of the wire crimping clamp on the power cord, it is generally thought of to set a U-shaped convex rib on the inner surface of the wire crimping clamp. However, for a wire crimping clamp made of metal, since it is formed by a die-casting process, the inner surface of the wire crimping seat is a demoulding surface. Setting a U-shaped convex rib on the inner surface of the wire crimping seat will result in a demoulding failure, which is not feasible in terms of technology.

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Combine the following Figures 1 to 8 The wire crimping clamp of the present invention is described.

[0029] like Figures 1 to 8 As shown, the wire crimping clamp provided in the embodiment of the present invention includes a wire crimping seat 1, a wire crimping plate 2 and a connecting member 3.

[0030] In a specific embodiment, the wire pressing seat 1 includes a supporting portion 4, a first connecting portion and a second connecting portion, and the supporting portion 4 has a wire groove 5 for passing cables such as power cables. The first connecting portion and the second connecting portion are both arranged on the supporting portion 4, and the second connecting portion is used to connect with the target component 17. The first connecting portion is used to connect with the wire pressing plate 2, and the wire pressing plate 2 and the first connecting portion can be detachably connected together through the connecting member 3.

[0031] The wire crimping seat 1 is used to connect with the target component 17, and the cable passes through the wire groove 5 of the wire crimping seat 1. The connecting piece 3 is used to detachably connect the wire crimping plate 2 and the wire crimping seat 1 so that the wire crimping plate 2 presses the cable tightly onto the wire crimping seat 1 to fix the cable.

[0032] The supporting portion 4 , the first connecting portion and the second connecting portion are integrally formed by a stamping process, and a stamping convex rib 6 is formed on the side wall of the wire groove 5 .

[0033] In this way, the wire clamp is designed as a sheet metal part and formed by a stamping process, so that it is possible to process the convex rib on the side wall of the wire groove 5. When the wire clamp clamps the cable, the stamped convex rib increases the friction between the cable and the wire clamp, which can improve the fixing force of the cable, and solves the problem of insufficient fixing force of the wire clamp made of metal material on cables such as power cables in the prior art.

[0034] In this embodiment, the stamped ribs 6 extend along the circumference of the wire groove 5. When the wire clamp fixes the cable, the contact area between each stamped rib 6 and the cable is increased, which increases the friction between the wire clamp and the cable, and can further improve the fixing force of the wire clamp on the cable.

[0035] At least two stamped convex ribs 6 are arranged on the wire groove 5. The stamped convex ribs 6 are spaced apart along the axial direction of the wire groove 5, which can further improve the fixing force of the wire clamp on the cable.

[0036] In the embodiment of the present invention, the first connecting portion includes a first connecting plate 7, and the first connecting plate 7 is located at the open end of the wire groove 5. The first connecting plates 7 are arranged in pairs, and the two first connecting plates 7 in each pair are respectively located on both sides of the axis of the wire groove 5, that is, along the circumference of the wire groove 5, the two first connecting plates 7 in each pair are respectively located at the two ends of the supporting portion 4.

[0037] like Figure 4 and Figure 5 As shown, the first connecting portion includes a pair of first connecting plates 7, and the pair of first connecting plates 7 are parallel to each other and located in the same plane.

[0038] The first connecting plate 7 is integrally formed with the supporting portion 4. Specifically, a stamping die can be used to stamp the plane plate at a position corresponding to the wire groove 5. The stamping die has a special-shaped punch, and a groove is arranged on the surface of the special-shaped punch. When the special-shaped punch is used to form the wire groove 5, a stamping convex rib 6 is also formed. In this way, the wire groove 5 and the stamping convex rib 6 can be processed in the same process using a stamping tool, which is conducive to improving work efficiency.

[0039] In this embodiment, a first connecting hole 8 is provided on the first connecting plate 7 , and a second connecting hole 9 is provided on the wire pressing plate 2 . When the wire pressing plate 2 is placed on the wire pressing seat 1 , the second connecting hole 9 corresponds to the first connecting hole 8 .

[0040] The connecting member 3 is located in the first connecting hole 8 and the second connecting hole 9 , and the first connecting plate 7 and the wire pressing plate 2 can be fastened together by using the connecting member 3 .

[0041] In some embodiments, a connecting bolt and a connecting nut can be selected as the above-mentioned connecting member 3, the threaded end of the connecting bolt passes through the first connecting hole 8 and the second connecting hole 9, the nut end of the connecting bolt abuts against the wire pressing plate 2, the connecting nut is threadedly connected to the connecting bolt, and the connecting nut abuts against the first connecting plate 7. Through the pre-tightening force of the connecting bolt and the connecting nut, the wire pressing plate 2 and the wire pressing seat 1 can be fastened together.

[0042] In other embodiments, one of the first connection hole 8 and the second connection hole 9 is set as a threaded hole, and a connecting bolt is selected as the above-mentioned connecting member 3. For example, the first connection hole 8 is set as a threaded hole, and the connecting bolt passes through the first connection hole 8 and the second connection hole 9, the nut end of the connecting bolt abuts against the wire pressing plate 2, and the threaded end of the connecting bolt is threadedly connected to the first connecting plate 7. The use of the connecting nut is avoided, and only the connecting bolt is used. Through the pre-tightening force of the connecting bolt and the first connecting plate 7, the wire pressing plate 2 and the wire pressing seat 1 can be fastened together.

[0043] In this embodiment, a flange portion is formed at one end of the first connecting hole 8, and the flange portion is in the shape of a hollow cylinder. The setting of the flange portion is equivalent to increasing the length of the first connecting hole 8. An internal thread is provided on the flange portion, and the connector 3 has an abutment portion and a threaded portion. The abutment portion is used to abut against the wire pressing plate 2, and the threaded portion has an external thread that matches the internal thread. When the wire pressing plate 2 and the wire pressing seat 1 are fastened together by the connector 3, the abutment portion of the connector 3 is abutted against the wire pressing plate 2, and the threaded portion of the connector 3 passes through the second connecting hole 9 of the wire pressing plate 2 and is threadedly connected to the flange portion on the wire pressing seat 1.

[0044] At this time, the connecting member 3 can be, but is not limited to, a screw or a bolt.

[0045] In the embodiment of the present invention, the second connecting portion includes a second connecting plate 10 .

[0046] The second connecting plate 10 is arranged at the first end of the supporting portion 4 along the axial direction of the wire trough 5, and the second connecting plate 10 is perpendicular to the axial direction of the wire trough 5. A notch is arranged on the second connecting plate 10, and the notch corresponds to the wire trough 5. The notch allows the cables in the wire trough 5 to pass through, so as to prevent the second connecting plate 10 from interfering with the cables.

[0047] The second connecting plate 10 can be connected to the target component 17. Specifically, the second connecting plate 10 and the target component 17 can be welded together by a welding process such as spot welding. Fixing the wire pressing seat 1 to the target component 17 by spot welding can reduce the stress deformation generated by the wire pressing seat 1 and the target component 17, and avoid the use of additional components, which is conducive to reducing costs.

[0048] The second connecting plate 10 is connected to a pair of first connecting plates 7, and the second connecting plate 10 is perpendicular to the first connecting plate 7. There is a gap between the edge of the notch and the supporting portion 4, so that the first connecting plate 7, the second connecting plate 10 and the supporting portion 4 can be integrally formed by a stamping process.

[0049] Specifically, during the processing, before stamping the wire groove 5 and the stamping convex rib 6, a hole 19 is first stamped on the raw material, and the hole 19 has an arc edge and a straight edge. The position on the raw material on the side where the straight edge is away from the arc edge is stamped, and the position on the raw material on the side where the straight edge is away from the arc edge is deformed into an arc surface to form the wire groove 5 and the stamping convex rib 6. Among the parts on the raw material on the side where the straight edge is away from the arc edge, the positions on both sides of the wire groove 5 are still planar, serving as the first connecting plate 7. The part on the raw material on the side where the straight edge is close to the arc edge is still planar.

[0050] Afterwards, the portion of the original material located on the side of the straight edge close to the arc edge is bent along the concave direction of the wire groove 5 until it is perpendicular to the axis of the wire groove 5. The bent portion is called the second connecting plate 10. At this time, the arc edge on the original material corresponds to the end edge of the wire groove 5.

[0051] The second connection part is formed at the first end of the supporting part 4 by a stamping process, and a bending rib is formed at the position where the first connection plate 7 is connected to the second connection plate 10 as the second connection part, which can increase the structural strength of the supporting part 4. Moreover, the notch on the second connection plate 10 is wrapped around the outer surface of the supporting part 4, which can reduce the deformation of the supporting part 4 and further increase the structural strength of the supporting part 4.

[0052] In this embodiment, a positioning structure is provided on the second connecting plate 10 , and the positioning structure is used to position the second connecting plate 10 at the position of the target component 17 .

[0053] The positioning structure may be, but is not limited to, a positioning hole or a positioning groove 18 .

[0054] Reference Figure 4 and Figure 5 The positioning structure is a positioning groove 18 arranged on the edge of the second connecting plate 10, and a positioning protrusion is arranged at the corresponding position of the target component 17. When the wire crimping seat 1 is installed on the target component 17, the positioning protrusion is located in the positioning groove 18. Through the interaction between the positioning protrusion and the positioning groove 18, the wire crimping seat 1 and the target component 17 can be positioned.

[0055] It should be noted that, during the stamping process, the outer contour size of the raw material used for processing the hole position 19 with straight edges and curved edges is slightly larger, and after the wire groove 5 and the stamping convex rib 6 are stamped on the raw material, a stamping and trimming process is performed according to the position of the wire groove 5. The above-mentioned positioning groove 18 can be completed in the stamping and trimming process.

[0056] In the embodiment of the present invention, the wire crimping seat 1 further includes a first reinforcing plate 11 .

[0057] Along the axial direction of the wire groove 5 , the first reinforcing plate 11 is located at the second end of the supporting portion 4 , the first reinforcing plate 11 is perpendicular to the axial direction of the wire groove 5 , and the first reinforcing plate 11 is connected to the first connecting portion and the supporting portion 4 .

[0058] The first reinforcing plate 11 can be formed at the second end of the supporting part 4 by a stamping process, and bending ribs are formed at the position where the first reinforcing plate 11 is connected to the supporting part 4 and at the position where the first reinforcing plate 11 is connected to the first connecting plate 7, thereby increasing the structural strength of the supporting part 4.

[0059] An avoidance groove 12 is provided on the first reinforcing plate 11 . The avoidance groove 12 corresponds to the connection position between the first connecting portion and the supporting portion 4 , and the avoidance groove 12 is located at a side of the first reinforcing plate 11 away from the supporting portion 4 .

[0060] The avoidance groove 12 serves as a material stacking port, which can ensure the smooth processing of the first reinforcing plate 11 through the stamping process, ensure the flatness of the processed first reinforcing plate 11, and effectively avoid problems such as wrinkles on the first reinforcing plate 11 and the supporting portion 4.

[0061] In the embodiment of the present invention, the wire pressing plate 2 includes a pressing portion 13 , a second reinforcing plate 14 and a third reinforcing plate 15 .

[0062] The second reinforcing plate 14 and the third reinforcing plate 15 are parallel to each other and located on the same side of the pressing portion 13 . The second reinforcing plate 14 and the third reinforcing plate 15 are respectively connected to two opposite edges of the pressing portion 13 to form an integrated structure.

[0063] When the wire pressing plate 2 is connected to the wire pressing seat 1 , the second reinforcing plate 14 and the third reinforcing plate 15 are located on the side of the clamping portion 13 away from the wire pressing seat 1 , and the distribution direction of the second reinforcing plate 14 and the third reinforcing plate 15 is parallel to the axial direction of the wire passing groove 5 .

[0064] The pressing plate 2 can be processed by a stamping process to form bending ribs at the position where the second reinforcing plate 14 is connected to the pressing part 13 and at the position where the third reinforcing plate 15 is connected to the pressing part 13, thereby increasing the structural strength of the pressing part 13.

[0065] It should be noted that the arrangement of the bending ribs at the above-mentioned various positions greatly increases the structural strength of the wire crimping seat 1, which is beneficial to reducing the thickness requirement of the wire crimping seat 1 for the raw material sheet, and the thickness can be as low as within the range of 0.7 to 1.2 mm.

[0066] In this embodiment, a protruding structure 16 is provided on the pressing portion 13, and the protruding structure 16 corresponds to the wire groove 5, and the protruding structure 16 is located on the side of the pressing portion 13 away from the second reinforcing plate 14 and the third reinforcing plate 15. When the pressing portion 13 is placed on the wire pressing seat 1, the protruding structure 16 is located at the opening of the wire groove 5, and the protruding structure 16 is used to press the cables in the wire groove 5, ensuring that the wire pressing plate 2 can effectively press against the cables, so as to provide sufficient fixing force for the cables with the wire pressing seat 1.

[0067] The protruding structure 16 can be processed by a stamping process. The protruding structure 16 can further increase the structural strength of the pressing portion 13.

[0068] In the embodiment of the present invention, the wire clamp is designed as a sheet metal part and formed by a stamping process, so that it is possible to process the convex ribs on the side wall of the wire groove 5. When the wire clamp clamps the cable, the stamped convex ribs increase the friction between the cable and the wire clamp, which can improve the fixing force of the cable.

[0069] When the cable is clamped and fixed by the wire clamp in the prior art, when the pulling force applied to the cable reaches 60 Newtons, the cable will produce a large displacement relative to the wire clamp. Through experiments, it is verified that when the wire clamp provided by the embodiment of the present invention is used to clamp and fix the cable, when a force of 100 Newtons is applied to the cable, the displacement that the cable can produce is less than 2 mm, which meets the requirements. The fixing force of the wire clamp provided by this embodiment on the cable is greatly improved.

[0070] On the other hand, an embodiment of the present invention further provides a vehicle air conditioner, comprising a wire crimping clamp provided by any of the above embodiments. The wire crimping clamp provided by any of the above embodiments can provide a greater fixing force for the cable, so the vehicle air conditioner provided by this embodiment has the advantages of stable cables and low failure rate. The derivation process of the beneficial effects of the vehicle air conditioner in the embodiment of the present invention is generally similar to the derivation process of the beneficial effects of the above wire crimping clamp, so it will not be repeated here.

[0071] In another aspect, the present invention further provides a method for processing a wire crimping clamp based on the wire crimping clamp provided in any of the above embodiments. The processing method of the wire crimping clamp described below can be referred to in correspondence with the wire crimping clamp described above.

[0072] like Figure 8 As shown, the processing method of the wire crimping clamp provided in the embodiment of the present invention includes the method steps of processing the wire crimping seat 1 of the wire crimping clamp provided in the above embodiment, specifically including the following steps 110 to 160.

[0073] Step 110, punch and trim the raw material to form an initial sheet, the initial sheet having a hole position corresponding to the notch, the hole position having an arc edge and a straight edge, the curvature of the arc edge is smaller than the curvature of the edge of the notch, and the edge of the initial sheet has a concave portion corresponding to the avoidance groove.

[0074] Step 120, stamping is performed on a portion of the initial sheet where the straight edge is away from the curved edge to form a first intermediate piece having a wire groove and a stamped rib, wherein the stamped rib is located on the wall surface of the wire groove, and the curvature of the curved edge is consistent with the curvature of the edge of the notch.

[0075] Step 130 , performing secondary punching and trimming on the first intermediate piece to form a second intermediate piece having a first connecting hole.

[0076] Step 140: flanging the first connection hole of the second intermediate piece to form a third intermediate piece having a flanging portion.

[0077] Step 150: Processing internal threads on the flanging portion of the third intermediate piece to form a fourth intermediate piece.

[0078] Step 160: bend and shape the fourth intermediate material to form a wire pressing seat having a first reinforcing plate and a second connecting plate.

[0079] The length direction of the raw material is consistent with the axial direction of the wire groove 5, and the width direction of the raw material is perpendicular to the length direction of the raw material.

[0080] First, the raw material is punched to process the hole position 19 corresponding to the notch, so that when the wire groove 5 is subsequently punched and formed, a part of the raw material can be processed into a curved surface, while the other part remains flat.

[0081] An arc-shaped groove is provided at the edge of the portion of the raw material located on the side of the straight edge close to the arc-shaped edge, serving as a positioning groove 18 .

[0082] The edge of the raw material located on the side of the straight edge away from the curved edge is processed with a concave portion, and the concave portion serves as an avoidance groove, which can facilitate the subsequent bending and forming of the first reinforcing plate 11.

[0083] After multiple experiments, it was verified that the curvature of the arcuate edge will increase when the initial sheet is punched to form the wire groove 5. In this embodiment, when the hole 19 corresponding to the notch is processed on the raw material, the curvature of the arcuate edge of the hole 19 is set to be relatively small, that is, the degree of curvature of the arcuate edge of the hole 19 is small, so as to adapt to the shape change when the wire groove 5 is punched, so as to ensure that the edge of the notch can correspond to the edge of the wire groove 5 when the second connecting plate 10 is subsequently bent.
