Description

Technical Field

[0001] This utility model relates to the field of tool and pliers technology, and in particular to a terminal crimping pliers with a positioner. Background Technology

[0002] Wire crimping pliers are tools used in the power industry for basic line construction and line maintenance. They are used to wrap exposed wires with metal crimping pliers to prevent the wires from loosening. For example, Chinese utility model patents with application numbers 202123085222.2 and 202321678875.8 demonstrate this. When using them, the metal crimping pliers are first inserted into the jaws of the pliers, and then the crimping teeth move to press the metal crimping pliers onto the wires to achieve the crimping function. However, in order to accommodate different specifications of wires, the crimping interface usually needs to be opened to the maximum extent. When crimping small-sized metal crimping pliers, the metal crimping pliers are prone to passing through the crimping interface or falling off, which causes drawbacks during crimping. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a terminal crimping clamp with a positioner. It uses a positioning plate to fix the metal crimping cylinder, thereby preventing it from passing through the crimping interface and making it more convenient to use.

[0004] This utility model discloses a terminal crimping pliers with a positioner, a first handle, and a second handle rotatably connected to the first handle. The first handle is provided with a protective plate and includes crimping teeth rotatably disposed on the protective plate, the crimping teeth surrounding to form a crimping interface. The second handle is provided with a rotating plate for driving the crimping teeth to rotate and move closer or separate to achieve crimping. The feature is that: a positioning plate is provided on the protective plate at the crimping interface position, the positioning plate is movably disposed on the protective plate, and the positioning plate is provided with a positioning hole, and the positioning plate can be moved to align the positioning hole with the crimping interface.

[0005] A further feature of this invention is that the positioning hole is funnel-shaped with the larger end facing outwards.

[0006] A further feature of this invention is that the positioning plate is oscillatingly mounted on the protective sheet, and the positioning plate has several positioning holes spaced apart along the circumferential direction, with the size of the positioning holes varying.

[0007] A further feature of this invention is that a top pin is provided on the protective plate facing the positioning plate, and the positioning plate is provided with a plurality of stop holes that are adapted to the top pin. When the positioning hole corresponds to the pressure interface, the top pin is located in the stop hole.

[0008] A further feature of this invention is that it includes a tension spring for driving the rotating plate to reset, with one end of the tension spring acting on the protective plate and the other end acting on the rotating plate.

[0009] The beneficial effects of this utility model are as follows: When in use, the positioning plate can be adjusted so that the corresponding positioning hole is located at the crimping interface position. Then, the metal crimping tube can be inserted into the positioning hole. At this time, the positioning hole can block the tail of the metal crimping tube, thereby preventing the metal crimping tube from directly passing through the crimping interface. Then, the wire is inserted into the inside of the metal crimping tube. By rotating the second handle, the rotating plate is driven to rotate. The rotating plate further drives the crimping teeth to rotate, thus realizing the crimping action, which makes crimping more convenient. Attached Figure Description

[0015] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] This utility model discloses a terminal crimping pliers with a positioner, a first handle 1, and a second handle 2 rotatably connected to the first handle 1. The first handle 1 is provided with a protective plate 3 and also includes crimping teeth 4 rotatably disposed on the protective plate 3. The crimping teeth 4 surround to form a crimping interface. The second handle 2 is provided with a rotating plate 5 for driving the crimping teeth 4 to rotate and move closer or separate to achieve crimping. The rotating plate 5 is provided with tooth grooves to drive the crimping teeth 4 to move. The specific details are conventional technical means and will not be described in detail here. In this utility model embodiment, the protective plate 3 is provided with a positioning plate 6 at the crimping interface position. The positioning plate 6 is rotatably disposed on the protective plate 3 and is provided with a positioning hole 61. The positioning plate 6 can be moved to align the positioning hole 61 with the crimping interface.

[0018] Using the above technical solution, the positioning plate 6 can be adjusted so that the corresponding positioning hole 61 is located at the crimping interface. Then, the metal crimping tube can be inserted into the positioning hole 61. At this time, the positioning hole 61 can block the tail of the metal crimping tube, thereby preventing the metal crimping tube from directly passing through the crimping interface. The wire is then inserted into the metal crimping tube. By rotating the second handle 2, the rotating plate 5 is driven to rotate. Furthermore, the rotating plate 5 drives the crimping teeth 4 to rotate, thereby realizing the crimping action, which makes crimping more convenient.

[0019] The positioning hole 61 is flared, with the larger end facing outward, which facilitates guiding the metal crimping cylinder into the crimping interface.

[0020] The positioning plate 6 is oscillatingly mounted on the protective plate 3. Several positioning holes 61 are spaced apart along the circumferential direction on the positioning plate 6, and the size of the positioning holes 61 is different. The position of the positioning holes 61 is adjusted by oscillation, which makes it more convenient to use. Furthermore, the use of positioning holes 61 of different sizes can be applied to more metal wire clamps of different specifications, thus making it suitable for use with wires of different specifications.

[0021] The protective plate 3 is provided with a top pin 7 on the side facing the positioning plate 6. The positioning plate 6 is provided with a plurality of stop holes 62 that are adapted to the top pin 7. When the positioning hole 61 corresponds to the crimping interface, the top pin 7 is located in the stop hole 62. The top pin 7 and the positioning plate 6 cooperate to prevent the positioning plate 6 from moving easily, making it more stable when the metal crimping cylinder and the wire are crimped.

[0022] It also includes a tension spring 8 for driving the rotating plate 5 to reset. One end of the tension spring 8 acts on the protective plate 3 and the other end acts on the rotating plate 5. After the pressing is completed, it can drive the pressing teeth 4 to reset, making it more convenient to use.
