Description
Technical Field
[0001] This utility model relates to the field of manual terminal crimping tools, and in particular to a terminal clamp. Background Technology
[0002] Currently, terminal pliers on the market typically consist of two pliers connected by a rotating joint. The two pliers form two opposing jaws along one side of the rotating joint connection, and two opposing handles along the other side of the rotating joint connection. The rotating joint usually adopts a ratchet pawl structure. The pliers are provided with polygonal holes, and multiple crimping terminals are rotatably arranged in the polygonal holes. The purpose of crimping is achieved by the multiple crimping terminals pressing against each other. However, this type of terminal pliers can only be used for crimping the jaws and crimping terminals, that is, it combines the functions of two types of pliers, and its functionality is very limited. Utility Model Content
[0003] The purpose of this utility model is to design a terminal clamp to overcome the shortcomings of the above-mentioned technology.
[0004] This utility model designs a terminal clamp, including a first handle and a second handle, which are movably connected by a ratchet mechanism. A first clamp body is movably connected to the top of the first handle, and a second clamp body is provided on the top of the second handle. The first clamp body and the second clamp body are stacked and movably connected. The top of the first clamp body and the second clamp body are provided with a first clamping jaw and a second clamping jaw that can bite each other. The first clamp body is provided with a pressure hole, and multiple pressure modules arranged in a centrally symmetrical manner are provided in the pressure hole. The pressure modules are rotatably connected between the first clamp body and the second clamp body by a pin. When the first clamp body and the second clamp body rotate relative to each other, they drive the pressure film to squeeze the workpiece toward the center of symmetry.
[0005] The first clamp body has a winding hole near its edge;
[0006] The first clamp body and the second clamp body are provided with a first pressing end and a second pressing end near the edge, which can be staggered and engaged with each other. The first pressing end and the second pressing end are respectively provided with a first biting end face and a second biting end face. The first biting end face is provided with a first tangential groove, and the second biting end face is provided with a second tangential groove that is adapted to the first tangential groove.
[0007] The first pressure end is also provided with a first shearing hole, and the second clamp body is provided with a second shearing hole that is adapted to the first shearing hole.
[0008] Preferably, both the first tangent groove and the second tangent groove are semi-circular grooves. When the first pressure end and the second pressure end rotate relative to each other, the first tangent groove and the second tangent groove interlock to cut the wire.
[0009] Further optimization involves the first tangential groove comprising multiple grooves of different sizes arranged side-by-side on the first engagement end face, and the second tangential groove corresponding to the first tangential groove one-to-one.
[0010] Preferably, the ratchet mechanism includes a ratchet floating plate, a locking plate, and an elastic damping plate. The ratchet floating plate is rotatably connected to the first handle, the locking plate is connected to the first handle and located below the ratchet floating plate, the elastic damping plate is disposed on the second handle and corresponds to the ratchet floating plate, one end of the ratchet floating plate is provided with a ball head, the top of the elastic damping plate is provided with a groove adapted to the ball head, the other end of the ratchet floating plate is provided with ratchet teeth, the end of the locking plate is provided with a protrusion adapted to the ratchet teeth, and a first spring is also provided between the locking plate and the first handle.
[0011] Further optimization involves providing a second spring between the bottom of the first clamp and the second clamp.
[0012] Further optimization involves providing a synchronization guide hole around the first clamp body near the pressure film hole, and a limiting pin on the second clamp body that inserts into the synchronization guide hole.
[0013] Preferably, the second handle is provided with a wire splitting part, the wire splitting part including a through hole opened on the second handle, and a wire splitting blade is provided in the center of the through hole.
[0014] Preferably, the number of the pressing modules is four or six, and the opposite ends of each pressing module are triangular blocks to serve as extrusion ends, with multiple extrusion ends forming an extrusion channel.
[0015] The technical advantages of this invention are as follows: In addition to the wire-crushing function of the jaws and crimping module, the terminal pliers have a first tangent groove and a second tangent groove on each of the two jaws. By rotating the two jaws relative to each other, the first tangent groove and the second tangent groove engage to achieve the cutting function. The two jaws are also provided with a first cutting hole and a second cutting hole, which engage to achieve the cutting function. The jaws are also provided with winding holes. The stripped wire bundles are inserted into their respective winding holes, and then by rotating the terminal pliers, the wire bundles in the winding holes are wound together. This not only eliminates the need for manual winding but also provides a good winding effect in one step. The handle is provided with a wire splitting part, which can split the wire in the middle to form two single-strand wires. The single-strand wires are then stripped and crimped by the jaws of the crimping pliers. The design is reasonable, space-saving, convenient and practical, thus realizing a multifunctional terminal pliers. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0022] This utility model includes a first handle 1 and a second handle 2, which are movably connected by a ratchet mechanism. A first clamp body 3 is movably connected to the top of the first handle 1, and a second clamp body 4 is provided on the top of the second handle 2. The first clamp body 3 and the second clamp body 4 are stacked and movably connected. The top of the first clamp body 3 and the second clamp body 4 are provided with a first clamping jaw 5 and a second clamping jaw 6 that can bite each other. The first clamp body 3 is provided with a pressing hole 7, and multiple pressing modules 8 arranged in a centrally symmetrical manner are provided in the pressing hole 7. The pressing modules 8 are rotatably connected between the first clamp body 3 and the second clamp body 4 by a pin. When the first clamp body 3 and the second clamp body 4 rotate relative to each other, they drive the pressing film to squeeze the workpiece toward the center of symmetry. The workpiece is usually an electric wire and a terminal connected to the end of the electric wire. That is, the pressing module 8 acts as a wire terminal and performs wire pressing by squeezing.
[0023] The number of pressing modules 8 is four or six. The opposite ends of each pressing module 8 are triangular blocks to serve as extrusion ends. Multiple extrusion ends enclose to form an extrusion channel. The multiple triangular blocks are also centrally symmetrical. The two right-angled sides of each triangular block structure are respectively attached to the right-angled sides of the adjacent triangular block structure, which play a guiding and driving role, making the pressing more stable and reliable.
[0024] Therefore, when using it, first insert the sleeve into the compression channel, then insert one end of the wire into the sleeve and further compress it through the compression channel to achieve wire crimping. Under the action of the ratchet mechanism, the first clamp body 3 and the second clamp body 4 are locked together, so that the size of the compression channel can be adjusted, that is, it can be used for different models and sizes of sleeves. Therefore, it can be used for different models and sizes of wires and sleeves.
[0025] The first clamp body 3 has a winding hole 9 near its edge. In this embodiment, there are four winding holes 9, which are arranged in a circular array on the surface of the first clamp body 3. The stripped wires are inserted into the winding holes 9 to form four separate wires. Then, the entire terminal clamp is rotated to twist the four wires into one, forming a single strand without the need for manual winding, which is very convenient.
[0026] Furthermore, the first clamp body 3 is provided with a synchronous guide hole 27 around the pressure hole 7, and the second clamp body 4 is provided with a limiting pin 28 that is inserted into the synchronous guide hole 27, which plays a certain guiding role in the rotation of the pressure module 8.
[0027] Near the edges of the first clamp body 3 and the second clamp body 4, there are first pressing ends 10 and second pressing ends 11 that can be staggered and engaged with each other. In this embodiment, both the first pressing ends 10 and the second pressing ends 11 are plate-shaped structures. The first pressing ends 10 and the second pressing ends 11 are respectively provided with a first engagement end face 12 and a second engagement end face 13. The first pressing ends 10 and the second pressing ends 11 rotate relative to each other as the first clamp body 3 and the second clamp body 4 rotate relative to each other, so that the first engagement end face 12 and the second engagement end face 13 form an engagement with each other, and the first engagement end face 12 and the second engagement end face 13 form an engagement with each other. It can be used for wire stripping, achieving the function of wire strippers; the first engagement end face 12 is provided with a first cutting groove 14, and the second engagement end face 13 is provided with a second cutting groove 15 that matches the first cutting groove 14. That is, the first cutting groove 14 and the second cutting groove 15 are staggered to form an engagement. In this embodiment, the first cutting groove 14 and the second cutting groove 15 are both semi-circular grooves. When the first pressing end 10 and the second pressing end 11 rotate relative to each other, the first cutting groove 14 and the second cutting groove 15 are staggered vertically and engage vertically, thereby cutting the wire.
[0028] Furthermore, the first tangent groove 14 includes multiple grooves of different sizes arranged side by side on the first engagement end face 12, and the second tangent groove 15 is arranged in a one-to-one correspondence with the first tangent groove 14, thereby realizing the cutting of wires of different sizes.
[0029] Furthermore, the first clamping end 10 is provided with a first shearing hole 16, and the second clamp body 4 is provided with a second shearing hole 17 that is adapted to the first shearing hole 16. In this embodiment, the first shearing hole 16 and the second shearing hole 17 are both round holes. The first shearing hole 16 and the second shearing hole 17 are initially staggered. As the first clamping end 10 and the second clamping end 11 engage with each other, the first shearing hole 16 and the second shearing hole 17 change from the original staggered state to the axially aligned state. At this time, the wire passes through the first shearing hole 16 and the second shearing hole 17. As the first clamp body 3 and the second clamp body 4 rotate, the first shearing hole 16 and the second shearing hole 17 return to the staggered state. Therefore, the wire is cut during the staggering process.
[0030] The ratchet mechanism includes a ratchet floating plate 18, a locking plate 19, and an elastic damping plate 20. The ratchet floating plate 18 is rotatably connected to the first handle 1. The locking plate 19 is connected to the first handle 1 and located below the ratchet floating plate 18. The elastic damping plate 20 is disposed on the second handle 2 and corresponds to the ratchet floating plate 18. One end of the ratchet floating plate 18 is provided with a ball head 21. The top of the elastic damping plate 20 is provided with a groove 22 that matches the ball head 21. The other end of the ratchet floating plate 18 is provided with a ratchet tooth 23. The end of the locking plate 19 is provided with a protrusion 24 that matches the ratchet tooth 23. A first spring 25 is also provided between the locking plate 19 and the first handle 1. A second spring 26 is provided between the bottom of the first clamping body 3 and the second clamping body 4. When the first handle 1 and the second handle 2 are squeezed, the first spring 25... The handle 1 abuts against the elastic damping plate 20 via the ratchet floating plate 18 and pushes the first clamp 3 to rotate. As the first clamp 3 rotates, the first jaw 5 and the second jaw 6 mesh with each other. At the same time, the first clamp 3 rotates and drives the pressing module 8 to rotate, causing multiple pressing modules 8 to close together to form a pressing channel. The rotation angle of the pressing module 8 is related to the size of the pressing channel. Under the interaction of the ratchet 23 and the protrusion 24, the rotation angle of the pressing module 8 is automatically adjusted, thereby adjusting the size of the pressing channel, and finally realizing the crimping connection of different terminals. It should be noted that the pressing channel will stop, so as to facilitate the insertion of the terminal wire into the pressing channel. Then, the end of the wire is inserted into the terminal, and finally the first clamp 3 and the second clamp 4 are driven to further crimp the pressing channel, thereby realizing the terminal crimping.
[0031] The second handle 2 is provided with a splitting part, which includes a through hole 29. The through hole 29 is vertically set on the front edge of the second handle 2. Of course, the through hole 29 can also be set on the first handle 1. The through hole 29 passes through the second handle 2. The cross-section of the through hole 29 is elliptical or waist-shaped. The inner wall of the through hole 29 has mounting grooves on opposite sides. A splitting blade 30 is inserted into the mounting groove. A limiting cover is provided at the opening of the through hole 29. The limiting cover is connected to the first handle 1 by fasteners. After the splitting blade 30 is inserted, the top is covered by the limiting cover to form a limit. The end of the splitting blade 30 facing the front is the blade. The height of the splitting blade 30 is less than the height of the through hole 29, so it is hidden in the through hole 29 and will not interfere with the grip of the handle.
[0032] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
