Description

Technical Field

[0001] This utility model relates to the field of hand tools, and in particular to a wire crimping pliers. Background Technology

[0002] Wire crimping pliers are a widely used hand tool in electrical wiring, network installation, and other operations. They are primarily used to securely and reliably crimp wires to connectors (such as RJ45 heads and terminal blocks). A typical wire crimping pliers configuration typically includes a pair of handles pivotally connected across each other, upper and lower jaws (or crimping dies) fixed to the front of the handles, and a self-locking mechanism located in the jaws. This self-locking mechanism automatically locks itself after the user applies a preset crimping force, ensuring a complete crimp each time and effectively preventing poor contact due to insufficient pressure.

[0003] To release the self-locking state after crimping, wire crimping pliers need an unlocking mechanism. In related technologies, the unlocking mechanism, such as an unlocking button or unlocking lever, is located inside the two handles. This layout is inconvenient to operate; for example, if the user's fingers are too large, it can be difficult to reach between the two handles, which can affect efficiency. Utility Model Content

[0033] Wire crimping pliers are a widely used hand tool in electrical wiring, network installation, and other operations. They are primarily used to securely and reliably crimp wires to connectors (such as RJ45 heads and terminal blocks). A typical wire crimping pliers configuration typically includes a pair of handles pivotally connected across each other, upper and lower jaws (or crimping dies) fixed to the front of the handles, and a self-locking mechanism located in the jaws. This self-locking mechanism automatically locks itself after the user applies a preset crimping force, ensuring a complete crimp each time and effectively preventing poor contact due to insufficient pressure.

[0034] To release the self-locking state after crimping, wire crimping pliers need an unlocking mechanism. In related technologies, the unlocking mechanism, such as an unlocking button or unlocking lever, is located inside the two handles. This layout is inconvenient to operate; for example, if the user's fingers are too large, it can be difficult to reach between the two handles, which can affect efficiency.

[0035] To address the aforementioned problems, this application discloses a wire crimping tool, comprising a fixing member, a movable jaw, a movable handle, and a locking assembly. One end of the fixing member forms a fixed jaw, and the other end forms a fixed handle. The movable jaw is hinged to the fixing member at a first point, which is located between the jaws of the wire crimping tool and the fixed handle. The movable handle is hinged to the movable jaw at a second point. The locking assembly includes a linkage part, a first elastic element, a mating part, and a second elastic element. The linkage is hinged to the fixing member at a third point and to the movable handle at a fourth point, the line connecting the first, second, third, and fourth points forming a quadrilateral; the first elastic member is connected to the linkage and configured to reset the linkage; the mating part is rotatably connected to the movable handle and cooperates with the linkage to limit the movable handle to rotate outward, the projection of the mating part along the vertical direction is completely within the projection of the movable handle, the vertical direction being perpendicular to the quadrilateral formed by the first, second, third, and fourth points; the second elastic member is connected to the mating part and configured to reset the linkage; the locking assembly further includes a forced unlocking component fixedly connected to the mating part, the forced unlocking component being located on the side of the movable handle facing or away from the user.

[0036] Please see Figures 1 to 10 This utility model embodiment provides a wire crimping tool 100, a movable jaw 20, a movable handle 30, and a locking assembly 40. One end of the fixing member 10 forms a fixed jaw 11, and the other end forms a fixed handle 12. The movable jaw 20 is hinged to the fixing member 10 at a first point 101, located between the jaws 105 of the wire crimping tool 100 and the fixed handle 12. The movable handle 30 is hinged to the movable jaw 20 at a second point 102. The locking assembly connects the movable handle 30 and the fixing member 10, with the connection point to the fixing member 10 at a third point 103 and the connection point to the movable handle 30 at a fourth point 104.

[0037] For ease of description, Figure 2 The diagram of the crimping pliers 100 serves as a directional reference for description. Specifically, the upper end of the crimping pliers 100 comprises the movable jaw 20 and the fixed jaw 11, while the lower end comprises the fixed handle 12 and the movable handle 30. The left side of the crimping pliers 100 features the movable jaw 20 and the movable handle 30, while the right side features the fixing element 10. The area between the two handles is the inner side, and the side where the two handles are far apart is the outer side. It is understood that the above directional description is merely for ease of subsequent description and is not a further limitation on the crimping pliers 100.

[0038] The first point 101 is located approximately in the middle of the movable pliers head 20. The second point 102 is located to the lower left of the first point 101, and is the lower end of the movable pliers head 20 and the upper end of the movable handle 30. The third point 103 is located to the lower right of the first point 101 and the second point 102, and is approximately in the middle of the fixing member 10. The fourth point 104 is located to the left of the third point 103 and is located below the second point 102.

[0039] When the user presses the fixed handle 12 and the movable handle 30, the lower end of the movable handle 30 rotates toward the fixed part 10, and the upper end of the movable handle 30 rotates away from the fixed part 10, thereby driving the upper end of the movable jaw 20 to rotate toward the fixed jaw 11, and the jaws 105 close to clamp the workpiece with a solid line.

[0040] In some embodiments, the movable pliers head 20 is generally triangular in shape and is formed by stacking two sheet metal parts. The movable handle 30 is also formed by two sheet metal parts, which are spaced apart vertically and clamp the movable pliers head 20. Fasteners are provided between the two sheet metal parts to fix them in place. The fastener 10 can be a bolt or rivet, etc. Correspondingly, the fastener 10 is also formed by two sheet metal parts spaced apart vertically.

[0041] The locking assembly 40 includes a linkage part 41, a first elastic member 42, a mating part 43, a second elastic member 44, and a forced unlocking assembly 430. The linkage part 41 is hinged to the fixing member 10 at a third point 103 and to the movable handle 30 at a fourth point 104. The lines connecting the first point 101, the second point 102, the third point 103, and the fourth point 104 form a quadrilateral. The first elastic member 42 is connected to the linkage part 41 and is configured to reset the linkage part 41. The mating part 43 is rotatably connected to the movable handle 30 and engages with the linkage part 41 to limit the outward rotation of the movable handle 30. The second elastic member 44 is connected to the mating part 43 and is configured to reset the linkage part 41.

[0042] Optionally, both the first elastic element 42 and the second elastic element 44 are tension springs. The upper end of the first elastic element 42 is connected to the fixing member 10, and the lower end of the first elastic element 42 is connected to the right end of the linkage part 41. It should be noted that the first elastic element 42 and the second elastic element 44 are not limited to tension springs. In some other embodiments, they can also be torsion springs or other structures that can reset the linkage part 41 and the mating part 43.

[0043] The engagement of the linkage part 41 and the mating part 43 prevents the jaws 105 from opening. When the linkage part 41 and the mating part 43 are disengaged, the first elastic element 42 and the second elastic element 44 allow the linkage part 41 and the mating part 43 to reset, thereby allowing the jaws 105 to open automatically.

[0044] In some embodiments, the projection of the mating part 43 is completely located within the projection of the movable handle 30 in the vertical direction. The vertical direction is perpendicular to the quadrilateral formed by the first point 101, the second point 102, the third point 103, and the fourth point 104, that is, perpendicular to... Figure 2 The direction of the wire clamp 100 shown.

[0045] It should be noted that the projection of the mating part 43 is completely located within the projection of the movable handle 30. This means that when the mating part 43 is in the reset state, or when the mating part 43 is in the locked rotation state, the mating part 43 may have most of its projection located within the projection of the movable handle 30, with a small portion located outside the movable handle 30.

[0046] The forced unlocking component 430 is fixedly connected to the mating part 43, and is located on the side of the movable handle 30 facing or away from the user. By rotating the unlocking component 430, the mating part 43 can be rotated, thereby achieving the purpose of forced unlocking.

[0047] By exposing the forced unlocking component 430 on the outer surface of the movable handle 30, specifically, on the side of the crimping pliers 100 facing the user, or in some embodiments on the side of the crimping pliers 100 away from the user, this external placement allows the user's thumb or forefinger to directly touch the forced unlocking component 430 without the need for other tools. This allows the user to easily rotate the mating part 43 to disengage the mating part 43 from the linkage part 41. In other words, the forced unlocking of the crimping pliers 100 of this application is simpler and more convenient.

[0048] In some embodiments, the forced unlock component 430 includes: Sleeve 4301; The lever 4302 is located on the circumferential side of the sleeve 4301.

[0049] Specifically, the length direction of the lever 4302 and the rotation direction of the sleeve 4301 form an angle, which can be set to 90 degrees, 45 degrees, etc., as long as it is convenient for the user to move the lever 4302. This application does not make a specific limitation. The sleeve 4301 is fixedly connected to the mating part 43 so that when the mating part 43 and the linkage part 41 engage or jam undesirably, rotating the lever 4302 will drive the sleeve 4301 and the mating part 43 to rotate synchronously, thereby releasing the locked state of the mating part 43 and the linkage part 41. The lever 4302 is located on the side of the movable handle 30 facing or away from the user.

[0050] Specifically, the sleeve 4301 is cylindrical in shape, and a rectangular hole is provided inside the sleeve 4301. A prism adapted to the rectangular hole is formed on the top of the mating part 43. The prism passes through the rectangular hole and is connected to a retaining pad to limit the forced unlocking component 430.

[0051] In some embodiments, the mating part 43 and the linkage part 41 are toothed, so that the mating part 43 and the linkage part 41 can rotate synchronously.

[0052] The mating part 43 includes a column 4311, a meshing tooth 4312, and a connecting block 4313. The column 4311 is rotatably connected to the movable handle 30. The meshing tooth 4312 is connected to the column 4311 and engages with the mating part 43. The connecting block 4313 is connected to the column 4311. One end of the second elastic member 44 is connected to the connecting block 4313, and the other end is connected to the movable handle 30. The sleeve 4301 is fitted onto the protrusion at the upper end of the column 4311.

[0053] In some embodiments, the linkage part 41 is elongated, with a plurality of teeth 410 at its left end, which mesh with the meshing teeth 4312, and a hole is formed at the end of the linkage part 41 away from the teeth 410 for engaging with the first elastic member 42.

[0054] Combination Figures 7 to 10 In some embodiments, the crimping pliers 100 further includes a clamping assembly 50 located in the jaws 105, and the clamping assembly 50 is detachably connected to at least one of a fixed clamping head 11 or a movable clamping head 20. Optionally, there are two clamping assemblies 50, one detachably connected to the fixed clamping head 11 and the other detachably connected to the movable clamping head 20. The two clamping assemblies 50 cooperate with each other to clamp the workpiece.

[0055] In some embodiments, at least one of the fixed jaw 11 or the movable jaw 20 is provided with a connecting groove 60, the connecting groove 60 having a first end 601 and a second end 602. The jaw assembly 50 includes a jaw portion 51 and a connecting portion 52. The jaw portion 51 is located in the jaw 105 and is provided with a retaining groove 5111, which is directly opposite to the first end 601 of the connecting groove 60. The connecting portion 52 passes through the connecting groove 60 and the retaining groove 5111 to connect the jaw portion 51 to the corresponding fixed jaw 11 or movable jaw 20. The connecting portion 52 is movable to the second end 602 to disengage from the retaining groove 5111.

[0056] Specifically, both the fixed pliers head 11 and the movable pliers head 20 are provided with a connecting groove 60. When the connecting part 52 is located at the first end 601, since the connecting part 52 passes through the slot 5111 and the connecting groove 60, the pliers head 51 can be connected to the corresponding fixed pliers head 11 or movable pliers head 20. When the connecting part 52 moves to the second end 602, it separates from the slot 5111, thereby allowing the pliers head 51 to separate from the corresponding pliers head.

[0057] The connecting part 52 has a structure that is larger at both ends and smaller in the middle, such as a screw and nut or a screw and washer. The end dimension of the connecting part 52 is larger than the connecting groove 60, while the middle dimension is smaller than the connecting groove 60, allowing the connecting part 52 to slide within the connecting groove 60 without separating from it. The slot 5111 is a non-closed slot with an opening, allowing the connecting part 52 to either enter or separate from the slot 5111 during movement within the connecting groove 60.

[0058] The clamp 51 can be fixed or removed by sliding the connecting part 52, and the process of installing or separating the clamp 51 is simple and quick.

[0059] In some embodiments, the length direction of the connecting groove 60 is inclined relative to the length direction of the jaws 105. This arrangement reduces the likelihood of the jaws 51 separating due to accidental contact.

[0060] In some embodiments, the connecting groove 60 has a fixing portion 603 and a releasing portion 604, with a first end 601 located in the fixing portion 603 and a second end 602 located in the releasing portion 604. The slot 5111 is directly opposite the fixing portion 603. Along the width direction of the connecting groove 60, the fixing portion 603 is larger than the releasing portion 604.

[0061] When the connecting part 52 is rotated to the corresponding position, it can slide between the fixed part 603 and the release part 604. When the connecting part 52 is not rotated to the corresponding position, the connecting part 52 can only be in the fixed part 603 and cannot enter the release part 604. This can further improve the stability of the connecting part 52 fixing the clamp 51.

[0062] In some embodiments, the fixing portion 603 is circular in shape, and the releasing portion 604 is racetrack-shaped. The middle portion of the connecting portion 52 is also racetrack-shaped, so that the connecting portion 52 can rotate on the fixing portion 603 and slide to the releasing portion 604 when it rotates to the position corresponding to the releasing portion 604.

[0063] In some embodiments, the connecting part 52 includes a connecting post 521 and two limiting ends 522. The connecting post 521 passes through the slot 5111 and the connecting groove 60. The two limiting ends 522 are disposed at both ends of the connecting post 521. When the connecting post 521 is located at the first end 601, it can rotate. When it rotates to the corresponding position, it can move to the second end 602.

[0064] The area of ​​the limiting end 522 is larger than the area of ​​the connecting post 521. The two limiting ends 522 can be the same or different. For example, if the connecting part 52 is a structure of bolt and washer or nut, then one of the limiting ends 522 can be the end of the bolt, and the other limiting end 522 can be a washer or nut. Optionally, the shape of the connecting post 521 is racetrack-shaped.

[0065] In some embodiments, the clamp 51 has a mounting block 511 and a clamp block 512, the mounting block 511 and the clamp block 512 are connected, the slot 5111 is located on the mounting block 511, and the mounting block 511 is disposed on the fixed clamp head 11 or the movable clamp head 20.

[0066] In summary, the embodiments of this application provide a wire crimping tool 100. By externalizing the forced unlocking component 430, the wire crimping tool 100 allows the user to easily access the forced unlocking component 430, thereby making forced unlocking easier. Furthermore, the sliding connection portion 52 allows control over the fixing or releasing of the clamp portion 51, facilitating the replacement or disassembly of the clamp portion 51.

[0067] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
