Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of crimping pliers, in particular to a square crimping pliers. BACKGROUND

[0002] Crimping pliers are a tool used to connect wires and terminals. By applying pressure, the wire and connector are tightly compressed, forming a reliable electrical connection. By applying pressure between the wire and the connector, the connector deforms on the wire, ensuring a secure and safe connection, reducing the risk of loose connections or electrical faults.

[0003] In the disclosed Chinese patent application, the publication number is CN211530372U, and the patent name is a self-adaptive labor-saving crimping pliers. This prior art sets a bifurcation on the dynamic handle and one end of the long handle, respectively, and forms three connecting fulcrums between the dynamic handle, the long handle, and the pliers head. A connecting rod mechanism is formed between the bifurcations of the dynamic handle and the long handle. When in use, the dynamic handle and the long handle drive the pliers head to compress, thereby facilitating the reduction of the compression action stroke of the dynamic handle and the long handle, making the crimping pliers smaller in size and more convenient for users to use. When the pliers head is used to compress terminals of different diameters, the pliers head contacts the terminals and then extrudes them, thereby tightly fixing the wire ends and the terminals. Although this prior art can press and fix the wire ends and the terminals, it has certain limitations in specific implementation. In the specific implementation of this prior art, each compression tooth is linked and matched with the tooth ring, and each compression tooth moves with the tooth ring and can achieve mutual engagement between each compression tooth. The tooth ring rotates to drive each tooth to rotate locally, and the tooth extrudes the wire and the terminal after local rotation, fixing them. Since the tooth rotates locally, it will cause the terminal to rotate locally, thereby affecting the connection strength between the terminal and the wire. UTILITY MODEL CONTENTS

[0010] Optionally, one end of the rotating block abuts against the matching plate, and the rotating block presses the matching plate after partial rotation on the mounting plate.

[0011] (Three) beneficial effects

[0012] The utility model provides a square wire pressing clamp, has the following beneficial effects:

[0013] This four-sided wire crimping tool, through the cooperation of two circular plates and a crimping assembly, achieves the effect of clamping and fixing wires and terminals. The rotating plate, after rotation, pushes the locking lever to slide along the locking groove. The locking lever slides closer to the second through hole, causing the clamping frame to move closer to the second through hole. The clamping frame slides along the groove, with the side edges of each clamping frame approaching the center of the second through hole. Each clamping frame squeezes the wire and terminal located in the first through hole, fixing the wire and terminal, effectively securing the wire end to the terminal. Compared with existing technologies, the clamping frames move in a sliding motion towards the wire and terminal, squeezing the wire and terminal from multiple directions, thus fixing them. This avoids the problem of localized rotation of the teeth in existing technologies, preventing the terminal from being locally rotated due to biased rotational forces, and thus avoiding affecting the connection strength between the terminal and the wire.

[0021] Please see Figs. 1 to 3 The present invention provides a technical solution: a four-sided crimping pliers, including a handle 1, an mounting plate 3 fixedly installed at one end of the handle 1, and a rotating block 2 hinged to one end of the mounting plate 3 near the handle 1.

[0022] Two circular plates 7 are fixedly connected to one end of the mounting plate 3 away from the handle 1. A first through hole is opened at the center of the circular plate 7, and a wire pressing assembly is installed between the two circular plates 7.

[0023] The pressure assembly includes a rotating plate 9, multiple clamping rods 10, and multiple pressing frames 11. A second through hole is formed at the center of the rotating plate 9. The first through hole and the second through hole are laterally aligned and connected. Multiple arc-shaped slots 12 are arranged on the rotating plate 9 along its circumference. The clamping rods 10 pass through the slots 12 on the rotating plate 9 and are slidably connected to the rotating plate 9 through the slots 12. The pressing frames 11 pass through the second through hole of the rotating plate 9, and both ends of the pressing frames 11 are fixedly connected to the two ends of the clamping rods 10, respectively.

[0024] One end of the slot 12 is farther from the center of the rotating plate (9) than the other end. The clamping frame 11 is U-shaped and consists of a pressing part and two sliding parts. The two ends of the pressing part are fixedly connected to the ends of the two sliding parts respectively. The pressing part is located in the second through hole, and the end of the sliding part away from the pressing part is fixedly connected to the end of the clamping rod 10.

[0025] The rotating plate 9 is located between the two circular plates 7, and the rotating plate 9 is rotatably connected to the two circular plates 7 respectively. The rotating plate 9 and the circular plates 7 are on the same center line. The circular plates 7 are provided with a plurality of sliding grooves 8 arranged in a ring array around the first through hole. The end of the clamping frame 11 is slidably connected to the sliding grooves 8 on the circular plates 7.

[0026] The sliding part of the clamping frame 11 is slidably connected to the groove 8 on the circular plate 7. The mounting plate 3 is used to support and fix the two circular plates 7.

[0027] After the rotating plate 9 rotates, it pushes the locking rod 10 to slide displacement through the locking groove 12. The locking rod 10 slides in the locking groove 12 and moves closer to or away from the center of the second through hole of the rotating plate 9.

[0028] When the clamping rod 10 moves closer to the center of the second through hole: the clamping rod 10 drives the pressing frame 11 to move closer to the center of the second through hole. At this time, the pressing frame 11 slides within the slide groove 8. The side edges (i.e., the pressing parts) of each pressing frame 11 approach the center of the second through hole. The pressing parts of each pressing frame 11 press the wire ends and terminals located in the second through hole, so that the wire ends and terminals are tightly fixed together.

[0029] When the clamping rod 10 moves away from the center of the second through hole: the clamping rod 10 drives the pressing frame 11 to move away from the center of the second through hole. At this time, the pressing frame 11 slides and moves within the slide groove 8. The side edges (i.e., the pressing parts) of each pressing frame 11 move away from the center of the second through hole, and the pressing parts of each pressing frame 11 move away from each other. The pressing parts of each pressing frame 11 no longer press the wire ends and terminals.

[0030] Specifically, a mating plate 5 is fixedly connected to the outer wall of the rotating plate 9, and a spring 6 is installed on one side wall of the mounting plate 3. The other end of the spring 6 is fixedly installed to the mating plate 5. A connecting strip 4 is hinged to the mating plate 5, and the end of the connecting strip 4 away from the mating plate 5 is slidably connected to the mounting plate 3.

[0031] The spring 6 provides elastic support for the mating plate 5, ensuring that it remains in its initial state when not subjected to external force. The connecting strip 4 prevents the mating plate 5 from tilting or shifting after prolonged use, ensuring that the mating plate 5 can only rotate around the center of the rotating plate 9.

[0032] Specifically, one end of the rotating block 2 abuts against the mating plate 5, and the rotating block 2 presses down on the mating plate 5 after partially rotating on the mounting plate 3.

[0033] The rotating block 2 is used to press the mating plate 5. When the rotating block 2 rotates partially on the mounting plate 3, the end of the rotating block 2 presses against the mating plate 5. After being subjected to force, the mating plate 5 rotates around the center of the rotating plate 9, and the mating plate 5 drives the rotating plate 9 to rotate, that is, the rotating plate 9 rotates on the circular plate 7. When the rotating plate 9 rotates, it pushes the locking rod 10 to move, and the locking rod 10 slides within the locking groove 12 of the rotating plate 9.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
