Technical Field

[0001] This utility model relates to the field of crimping tools, specifically a three-way crimping tool pliers for cable cores. Background Technology

[0002] High-speed rail is currently a key mode of transportation being developed in my country. Signal cables are an important material for connecting various outdoor signaling equipment. When connecting signal cables to various terminals, in order to ensure a reliable connection between the cable core and each terminal and to prevent poor wiring caused by vibrations generated during the movement of high-speed trains, reinforced connectors must be crimped onto the cable core during construction. However, existing crimping tools are inconvenient to use and have low crimping speed and quality. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model provides a three-way crimping tool for cable cores, which can quickly crimp O-type connectors and OT-type core reinforcement connectors. It has a simple structure, is easy to use, and can quickly crimp the copper lugs of cable cores with good crimping effect.

[0004] The technical solution provided by this utility model is as follows: A three-way crimping tool for cable cores, comprising an outer fixed handle seat and an inner rotating handle seat rotatably connected to the outer fixed handle seat. Both the outer fixed handle seat and the inner rotating handle seat have through holes in their middle portions. The outer fixed handle seat includes an annular outer frame and a first handle disposed on the side of the annular outer frame. The inner rotating handle seat includes a cylindrical fixed platform for mounting inside the annular outer frame and a second handle disposed on the outer side of the fixed platform. The fixed platform has three grooves evenly distributed along its center for placing sliding clamps. Each sliding clamp has a fixed rack disposed on its upper outer side. A rotating gear is correspondingly mounted on the fixed platform outside each fixed rack. Each rotating gear meshes with its corresponding fixed rack. The outer sides of the three rotating gears are connected to an inner gear ring.

[0005] Furthermore, a first limiting pin is provided on the inner side of the first handle to limit the minimum size of the inner rotating handle seat.

[0006] Furthermore, the annular outer frame has a notch to form an area for rotating the inner rotating handle seat.

[0007] Furthermore, an arc-shaped groove is provided on the upper inner wall of the annular outer frame for inserting an elastic retaining ring. The bottom surface of the elastic retaining ring fits against the top surface of the inner rotating handle seat, limiting the assembly of the inner rotating handle seat and the outer fixed handle seat.

[0008] Furthermore, a second limiting pin is provided on the outer side of the second handle to limit the maximum rotation dimension of the inner rotating handle seat.

[0009] Furthermore, each of the sliding clamps is arrow-shaped, and the head of the sliding clamp has an arc-shaped clamping opening. When the three sliding clamps move to dock, their arc-shaped clamping openings form a circle.

[0010] Furthermore, each of the sliding clamps and fixed racks is provided with corresponding bolt mounting holes, and the sliding clamps and fixed racks are connected by fixing screws.

[0011] Furthermore, each of the fixed racks has a mounting hole on its outer fixed platform, through which the rotating gear is connected to the inner rotating handle seat via a fixed shaft.

[0012] This utility model has a simple structure and reasonable design, which can quickly crimp the crimping plate onto the cable core. It is easy to use, has a good fixing effect, improves the efficiency of this construction process, ensures the crimping quality of the copper lug, ensures traffic safety, has low cost, high efficiency, and has high practical value.

[0024] like Figure 1-5The cable core crimping tool shown includes an outer fixed handle seat 1 and an inner rotating handle seat 2 rotatably connected to the outer fixed handle seat 1. Both the outer fixed handle seat 1 and the inner rotating handle seat 2 have through holes 3 in their middle parts. The outer fixed handle seat 1 includes an annular outer frame 101 and a first handle 102 disposed on the side of the annular outer frame 101. The inner rotating handle seat 2 includes a cylindrical fixed platform 201 for mounting inside the annular outer frame 101 and a second handle 202 disposed on the outer side of the fixed platform 201. The fixed platform 201 has three grooves 203 evenly distributed along its center for placing sliding clamps 4. The grooves 203 allow the sliding clamps 4 to be installed and moved. Each sliding clamp 4 has a fixed rack 5 disposed on its upper outer side. Each fixed platform 201 on the outer side of each fixed rack 5 is correspondingly mounted with a rotating gear 6. Each rotating gear 6 meshes with the corresponding fixed rack 5. The outer sides of the three rotating gears 6 are connected to an inner gear ring 7, which has teeth that match the entire device.

[0025] The annular outer frame 101 has a notch 104 to form the area for the inner rotating handle seat 2 to rotate. A first limiting pin 103 is provided on the inner side of the first handle 102 to limit the minimum size of the inner rotating handle seat 2 when pressed. An arc-shaped groove 105 is formed on the circumferential direction of the upper inner wall of the annular outer frame 101 for inserting an elastic retaining ring 8. The bottom surface of the elastic retaining ring 8 fits against the top surface of the inner rotating handle seat 2, limiting the assembly of the inner rotating handle seat 2 and the outer fixed handle seat 1. The elastic retaining ring 8 can stably fix the device.

[0026] The second handle 202 is provided with a second limiting pin 204 on its outer side, which is used to limit the maximum size of the rotation of the inner rotating handle seat 2.

[0027] Each of the sliding clamps 4 is arrow-shaped, and the head of the sliding clamp 4 has an arc-shaped clamping opening 401. When the three sliding clamps 4 move to dock, their arc-shaped clamping openings 401 form a circle. Each of the sliding clamps 4 and the fixed rack 5 is provided with corresponding bolt mounting holes 402, and the sliding clamp 4 and the fixed rack 5 are connected by fixing screws 9.

[0028] Each of the fixed racks 5 has a mounting hole 205 on its outer fixed platform 201. The rotating gear 6 has a mounting hole for the fixed shaft 10 to pass through, and the rotating gear 6 is connected to the inner rotating handle seat 2 through the fixed shaft 10.

[0029] The three-way crimping tool pliers of this utility model are assembled from various parts. In actual use, rotating the inner rotating handle seat 2 drives the three evenly distributed rotating gears 6 to rotate through the inner gear ring 7. The rotating gears 6 drive the fixed rack 5 to move, and the fixed rack 5 drives the sliding clamp 4 to move and open. After the device is opened, the cable core wire and O-type connector and OT-type core wire reinforcement connector that have been wound can be inserted.

[0030] After the device is turned on, insert the O-type connectors and OT-type reinforcing connectors of the cable cores to be crimped into the crimping holes. By pressing the outer fixed handle seat 1 and the inner rotating handle seat 2, the rotating gear 6 is driven to rotate through the inner gear ring 7. The fixed rack 5 drives the sliding clamp 4 to move and close, thus completing the crimping of the O-type connectors and OT-type reinforcing connectors.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
