[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0029] The embodiment of the present application provides a wire crimping device to solve the technical problem that the wire crimping clamp in the prior art cannot be applied to cables of different sizes. The following will be described in conjunction with the accompanying drawings.

[0030] In the embodiments of the present application, Figure 1 , Figure 5 and Figure 6 As shown, the wire pressing device includes a base plate 10, a movable plate 20 and a limiting structure 30, wherein a first clamping plate 11 is provided on the base plate 10; the movable plate 20 is slidably arranged on the base plate 10, and a second clamping plate 21 opposite to the first clamping plate 11 is provided on the movable plate 20, and a receiving groove 12 for accommodating the cable 100 is formed between the first clamping plate 11 and the second clamping plate 21; the limiting structure 30 includes a limiting rack 31 and a limiting member 32, the limiting rack 31 is arranged on one of the base plate 10 and the movable plate 20, and the limiting member 32 is arranged on the other of the base plate 10 and the movable plate 20; during the sliding process of the movable plate 20, the second clamping plate 21 moves toward the direction close to the first clamping plate 11 to fix the cable 100 in the receiving groove 12, and the limiting member 32 is sequentially inserted into the tooth groove corresponding to the limiting rack 31.

[0031] It should be noted that the related art wire clamp includes a pressure plate and a pressure cover. The pressure plate is provided with a groove for placing the cable. During installation, the cable is first limited on the pressure plate through the pressure cover, and then the pressure plate and the pressure cover are connected by screws to fix the cable. However, the above-mentioned wire clamp can only be applied to cables of a specific size and cannot fix cables of different sizes. When there is a deviation in the size of the cable, the wire clamp may not be tight or even loose, which may lead to poor contact of the cable and cause safety risks.

[0032] To this end, the wire crimping device provided in the present application is provided with a first clamping plate 11 on the base plate 10, and a second clamping plate 21 is provided on the movable plate 20. The second clamping plate 21 can be controlled to approach or move away from the first clamping plate 11 by sliding the movable plate 20 on the base plate 10, so that the distance between the first clamping plate 11 and the second clamping plate 21 can be adjusted according to actual needs, so that the wire crimping device can adapt to cables 100 of different sizes, avoiding poor contact of the cables 100 due to loose wire crimping, thereby improving the reliability of the air conditioner; at the same time, in the process of the second clamping plate 21 approaching the first clamping plate 11, the limiting member 32 can be sequentially inserted into the corresponding tooth groove of the limiting rack 31, thereby limiting the second clamping plate 21 from moving away from the first clamping plate 11, so that the cable 100 can be stably compressed, thereby improving the reliability of the wire crimping device.

[0033] For details, please refer to Figure 1 , Figure 5 and Figure 6 The bottom plate 10 and the first clamping plate 11 are both flat plate structures, and the first clamping plate 11 is vertically arranged at one end of the bottom plate 10, so that the first clamping plate 11 and the bottom plate 10 form an "L"-shaped structure. The movable plate 20 can be arranged in a square frame, a flat plate, a strip, etc., and the second clamping plate 21 can be integrally arranged at one end of the movable plate 20, so that the second clamping plate 21 can slide on the bottom plate 10 synchronously with the movable plate 20.

[0034] In this embodiment, guide rails, guide grooves and other structures can be provided on the bottom plate 10, and the movable plate 20 can be installed in the guide rails or guide grooves accordingly, so as to achieve a sliding connection between the movable plate 20 and the bottom plate 10. In addition, in this embodiment, the movable plate 20 can be driven to slide on the bottom plate 10 manually, or the motor can provide torque to push the movable plate 20 to slide on the bottom plate 10.

[0035] See also Figure 1 The movement direction of the movable plate 20 is perpendicular to the plane where the first clamping plate 11 is located, and the first clamping plate 11 and the second clamping plate 21 are arranged in parallel, so that the distance between the first clamping plate 11 and the second clamping plate 21 can be changed by sliding the movable plate 20. The first clamping plate 11, the second clamping plate 21 and the bottom plate 10 are enclosed to form a receiving groove 12, and the top surface of the receiving groove 12 is open, and the opening is used to place the cable 100.

[0036] When the cable 100 needs to be fixed, the cable 100 is first placed in the accommodating groove 12 through the above-mentioned opening, and then the movable plate 20 is slid toward the side where the first clamping plate 11 is located. At this time, the second clamping plate 21 gradually approaches the first clamping plate 11, and the area of ​​the accommodating groove 12 gradually decreases. Finally, the first clamping plate 11 and the second clamping plate 21 are both in contact with the cable 100 and provide an extrusion force on the cable 100, thereby fixing the cable 100 between the first clamping plate 11 and the second clamping plate 21. At the same time, the limiting member 32 is inserted into the corresponding groove of the limiting rack 31, which can prevent the second clamping plate 21 from moving away from the first clamping plate 11 and causing the cable 100 to loosen.

[0037] Furthermore, the limit member 32 is movably arranged on the bottom plate 10, the limit rack 31 is arranged on the side of the movable plate 20, and the limit rack 31 extends along the sliding direction of the movable plate 20, so that when the movable plate 20 slides toward the first clamping plate 11, the limit member 32 can be moved and sequentially inserted into the corresponding tooth grooves of the limit rack 31.

[0038] Optionally, in one embodiment, see Figure 1-Figure 3 Two columns 13 are arranged at intervals on the bottom plate 10. The two columns 13 and the bottom plate 10 are enclosed to form a slide groove 14. The slide groove 14 extends in a direction close to the first clamping plate 11. The movable plate 20 is slidably set in the slide groove 14, and each column 13 is respectively provided with a retaining rib 15 extending toward another column 13.

[0039] Specifically, the two columns 13 extend along the first clamping plate 11, the movable plate 20 slides between the two columns 13, and the shape and size of the slide groove 14 are adapted to the shape and size of the movable plate 20, so that the movable plate 20 can stably slide in the slide groove 14. Exemplarily, the movable plate 20 slides in the length direction of the bottom plate 10, the two columns 13 are used to limit the movable plate 20 in the width direction of the bottom plate 10, and the retaining ribs 15 are used to limit the movable plate 20 in the height direction of the bottom plate 10, so as to ensure that the movable plate 20 does not fall out of the slide groove 14 during the sliding process.

[0040] For further information, see Figure 1 The second clamping plate 21 is located on the outside of the slide groove 14. When the movable plate 20 moves a certain distance in the direction away from the first clamping plate 11, the second clamping plate 21 can abut against the end of the column 13. That is, through the cooperation between the column 13 and the second clamping plate 21, the movable plate 20 can also be limited in the length direction of the bottom plate 10 to prevent the movable plate 20 from escaping from the slide groove 14.

[0041] In an optional embodiment, the columns 13 and the retaining ribs 15 are both elastic parts, for example, the columns 13 and the retaining ribs 15 are both made of plastic material, so that when the movable plate 20 and the base plate 10 are assembled, the columns 13 and the retaining ribs 15 are elastically deformed, so that the movable plate 20 can be inserted into the slide groove 14, thereby realizing the assembly of the movable plate 20.

[0042] In addition, in other embodiments, one of the columns 13 and the base plate 10 can be separately provided. When the movable plate 20 and the base plate 10 are assembled, the movable plate 20 is first installed in the slide groove 14, and then the column 13 is fixed to the base plate 10 by bonding or screw connection, which can also realize the assembly of the movable plate 20.

[0043] Optionally, in one embodiment, see Figure 1 The limiting rack 31 includes a first rack 311, which is disposed on the movable plate 20. A first gear 40 is disposed on the bottom plate 10. The first gear 40 is transmission-connected to the first rack 311 so that the first gear 40 drives the second clamping plate 21 to move closer to or away from the first clamping plate 11.

[0044] Specifically, the first rack 311 is disposed on the side of the movable plate 20, and the first rack 311 extends toward the direction close to the first clamping plate 11, and the first gear 40 is rotatably connected to the bottom plate 10, so that the first gear 40 can rotate relative to the bottom plate 10. Figure 1 As shown, the first gear 40 is meshed with the first rack 311 . When the first gear 40 is driven clockwise, the movable plate 20 moves away from the first clamping plate 11 ; when the first gear 40 is driven counterclockwise, the movable plate 20 moves toward the first clamping plate 11 .

[0045] See also Figure 1 In this embodiment, the limit member 32 and the base plate 10 can be set to be rotatably connected, and a protrusion 18 can be set on the base plate 10 between the second clamping plate 21 and the limit member 32. When the first clamping plate 11 and the second clamping plate 21 clamp the cable 100, one end of the limit member 32 is inserted into the tooth groove of the first rack 311, and the other end of the limit member 32 is abutted against the protrusion 18. Under the action of the protrusion 18, the end of the limit member 32 away from the first rack 311 will not move in the direction close to the second clamping plate 21, thereby limiting the second clamping plate 21 from being away from the first clamping plate 11, so that the cable 100 can be stably compressed.

[0046] Optionally, in one embodiment, see Figure 2-Figure 4 The limiting rack 31 also includes a second rack 312 arranged on the movable plate 20, the second rack 312 is arranged opposite to the first rack 311, and a second gear 50 meshing with the first gear 40 is provided on the bottom plate 10, and the second gear 50 is transmission-connected to the second rack 312.

[0047] For details, please refer to Figure 2 and Figure 3 The movable plate 20 and the second clamping plate 21 are combined to form a roughly "mouth"-shaped structure, the first rack 311 and the second rack 312 are arranged on two opposite sides of the movable plate 20, and the first gear 40 and the second gear 50 are both located in the movable plate 20, and the second gear 50 and the second rack 312 are meshed.

[0048] It can be understood that when one of the first gear 40 and the second gear 50 is driven, the other gear will rotate synchronously and drive the corresponding rack to move, thereby driving the movable plate 20 to slide through the first gear 40 and the second gear 50 at the same time, which is beneficial to ensure that the movable plate 20 is evenly stressed on both sides of the slide groove 14, so that the second clamping plate 21 can provide a more uniform extrusion force on the cable 100, thereby improving the fixing effect of the cable 100.

[0049] Optionally, in one embodiment, see Figure 4 , a mounting hole 16 is provided on the base plate 10, a mounting column 322 is provided on the limiting member 32, and the mounting column 322 is installed in the mounting hole 16; and / or, two shaft holes 17 are provided on the base plate 10, and a rotating shaft 42 is provided on the first gear 40 and the second gear 50, and the rotating shaft 42 is installed in the corresponding shaft hole 17.

[0050] Specifically, the mounting hole 16 is a round hole, and the mounting hole 16 is inserted into the mounting hole 16 by interference fit, so as to realize the connection between the limiting member 32 and the bottom plate 10, and the limiting member 32 will not rotate relative to the bottom plate 10, thereby ensuring the limiting effect of the limiting member 32. Since the first gear 40 and the second gear 50 both need to rotate relative to the bottom plate 10, the rotating shaft 42 of the first gear 40 and the rotating shaft 42 of the second gear 50 can be installed in the corresponding shaft hole 17 by clearance fit.

[0051] Optionally, in one embodiment, see Figure 3 The wire crimping device includes a driving member, which is connected to the first gear 40 to drive the first gear 40 to rotate; or, a driving operating part 41 is provided on the first gear 40, and the driving operating part is suitable for connecting with a wrench tool.

[0052] Specifically, the driving member can be an electric motor. In this embodiment, the output shaft of the driving member can be directly connected to the first gear 40 to drive the first gear 40 to rotate, or the driving member can be connected to a belt to drive the first gear 40 to rotate through belt transmission, and then the first gear 40 drives the second gear 50 to rotate, thereby synchronously driving the movable plate 20 to slide through the first gear 40 and the second gear 50.

[0053] The driving operating part 41 can be a slotted slot, a cross slot, a hexagonal hole, a hexagonal head, etc. The wrench tool includes a slotted screwdriver, a cross screwdriver, a hexagonal wrench, a hexagonal socket, etc. Among them, the slotted screwdriver is used to cooperate with the slotted slot, the cross screwdriver is used to cooperate with the cross slot, the hexagonal wrench is used to cooperate with the hexagonal hole, and the hexagonal socket is used to cooperate with the hexagonal head, so that the first gear 40 is manually rotated in the above manner.

[0054] In other embodiments, the driving member may be connected to the second gear 50 , or the driving operating part 41 may be provided on the second gear 50 .

[0055] Optionally, in one embodiment, see Figure 3 The limiting rack 31 includes a first rack 311 and a second rack 312 which are arranged relatively at an interval, and the limiting member 32 is arranged between the first rack 311 and the second rack 312 .

[0056] See also Figure 2 and Figure 3 The movable plate 20 and the second splint 21 are combined to form a structure roughly in the shape of a "mouth", the first rack 311 and the second rack 312 are arranged on two opposite sides of the movable plate 20, and the first rack 311 and the second rack 312 both extend along the sliding direction of the movable plate 20, and the limit member 32 is arranged between the first rack 311 and the second rack 312 and can be engaged with the first rack 311 and / or the second rack 312 to prevent the movable plate 20 from sliding in the direction away from the first splint 11 through the resistance provided by the limit member 32.

[0057] For further information, see Figure 3 and Figure 4 The limiting member 32 is an elastic limiting member 32 , and one end of the limiting member 32 is engaged with the first rack 311 , and the other end of the limiting member 32 is engaged with the second rack 312 .

[0058] Specifically, in the present embodiment, the limit member 32 is fixed on the base plate 10. When the movable plate 20 moves toward the direction close to the first clamping plate 11, the limit member 32 is elastically deformed and thereby sequentially engages with the corresponding tooth grooves of the first rack 311 and the second rack 312. When the movable plate 20 stops sliding, the two ends of the limit member 32 are respectively engaged with the first rack 311 and the second rack 312, so that the movable plate 20 will not move away from the first clamping plate 11, thereby ensuring the fixing effect of the wire pressing device on the cable 100.

[0059] For further information, see Figure 3 and Figure 7The stopper 32 is V-shaped and has a V-shaped opening 321, which is disposed toward the second clamping plate 21. The stopper 32 includes a first plate body and a second plate body, both of which are flat plates. The V-shaped stopper 32 can be formed by connecting the end of the first plate body and the end of the second plate body. The first plate body is engaged with the first rack 311, and the second plate body is engaged with the second rack 312.

[0060] By setting the V-shaped opening 321 toward the second clamping plate 21, when the movable plate 20 slides in the direction close to the second clamping plate 21, the first plate body and the second plate body are elastically deformed toward the inside after being subjected to force, and the angle of the V-shaped opening 321 becomes smaller at this time, so that the movable plate 20 can slide smoothly in the direction close to the second clamping plate 21; when the movable plate 20 slides in the direction away from the first clamping plate 11, since the force directions of the limit member 32 are opposite at this time, the first plate body and the second plate body are elastically deformed toward the outside after being subjected to force, and the angle of the V-shaped opening 321 becomes larger at this time, making the first plate body and the first rack 311 more firmly connected, and the second plate body and the second rack 312 more firmly connected, effectively limiting the movement of the second clamping plate 21 in the direction away from the first clamping plate 11.

[0061] Optionally, in one embodiment, see Figure 5 and Figure 6 The first clamping plate 11 is provided with a plurality of first ribs 111, which are arranged on the side of the first clamping plate 11 facing the second clamping plate 21; and / or, the second clamping plate 21 is provided with a plurality of second ribs 211, which are arranged on the side of the second clamping plate 21 facing the first clamping plate 11. The first ribs 111 and the second ribs 211 can both be arranged in a strip shape, and the arrangement of the first ribs 111 and / or the second ribs 211 can achieve an anti-slip effect, preventing the cable 100 from sliding out of the receiving groove 12 during the process of fixing the cable 100 by the first clamping plate 11 and the second clamping plate 21, thereby improving the wire pressing efficiency.
