Description

Technical Field

[0001] This utility model relates to the field of electrical tool technology, and in particular to a tool for quickly making eyelets for terminal blocks. Background Technology

[0002] During the maintenance of electric actuators in the power plant electrical maintenance department, it is necessary to disconnect and reconnect the secondary circuit of the electric actuators. When disconnecting the wires, the eyelets at the cable ends need to be straightened, and when reconnecting, they need to be manually bent back into eyelets and tightened with screws for reinforcement, which is time-consuming.

[0003] Currently, there are no specialized tools for fabricating eyelets in the electrical maintenance field of power plants, resulting in low work efficiency. Furthermore, the quality of wire disconnection and reconnection largely depends on the operator's experience and skill. If the operator lacks sufficient experience and skill, the eyelets may be of substandard size and quality, potentially causing overheating or other hazards during later use, directly jeopardizing the safety and stability of the electric actuator. Therefore, this invention proposes a tool for quickly fabricating eyelets for wiring terminals to address the shortcomings of existing technology. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a tool for quickly manufacturing eyelets for cable terminals, thereby solving the problems of low efficiency and unsatisfactory quality in the manufacturing of eyelets for cable ends in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A tool for quickly fabricating eyelets for terminal blocks includes a first clamping arm and a second clamping arm. The first clamping arm has a mounting groove. The second clamping arm is symmetrically arranged with the first clamping arm and is rotatably connected to the first clamping arm at the mounting groove via a connecting shaft. The inner wall of the front end of the first clamping arm has a first toothed surface, and the inner wall of the front end of the second clamping arm has a second toothed surface. The front of the first clamping arm has a first graduated groove, and the top of the first clamping arm has a second graduated groove. Multiple first and second graduated grooves are provided. The second clamping arm has multiple positioning grooves. The width of the multiple positioning grooves increases sequentially from the front end of the second clamping arm to the rear. After the front ends of the first and second clamping arms are closed, a protective sleeve is fitted on their outer sides.

[0006] A further improvement is that protective rubber sleeves are provided at the rear ends of both the first and second clamp arms.

[0007] A further improvement is that the positions of the plurality of first scale grooves and the plurality of second scale grooves are adapted to each other, and scale lines are provided in the plurality of first scale grooves and the plurality of second scale grooves.

[0008] A further improvement is that both the first and second tooth surfaces are composed of multiple continuously arranged single teeth, and the cross-section of each single tooth is a triangular structure.

[0009] A further improvement is that: the first clamp arm is provided with a first positioning magnetic groove, the second clamp arm is provided with a second positioning magnetic groove, and one end of the sheath is provided with a first magnetic block and a second magnetic block that are adapted to the first positioning magnetic groove and the second positioning magnetic groove.

[0010] A further improvement is that: a pull ring is provided at the end of the sheath away from the first magnetic block and the second magnetic block, and a hanging ring is provided on the inner side wall of the first clamp arm.

[0011] The beneficial effects of this utility model are as follows: This utility model sets up a clamp body structure composed of a first clamp arm, a second clamp arm, and a connecting shaft. By setting multiple first and second scale grooves with corresponding positions on the first clamp arm, the first and second scale grooves can conveniently indicate the stripping length of the wire, enabling precise stripping of the wire. The multiple positioning grooves on the second clamp arm are all of different sizes, which can correspond to the diameter of the copper wire in different wires. After the first and second clamp arms fix the copper wire in the wire, the copper wire can be bent at the positioning groove of the corresponding size to form eyelets of different sizes on the wire.

[0012] The tool of this invention can produce standardized eyelets for terminal blocks, so that the production of eyelets for terminal blocks no longer relies on the experience and skills of the operators, and can achieve rapid and mass production of eyelets for terminal blocks.

The front of the first clamp arm 1 has a first graduated groove 6, and the top of the first clamp arm 1 has a second graduated groove 7. Multiple first graduated grooves 6 and multiple second graduated grooves 7 are provided. In this utility model, because different types of screws require... Eyelets are made for cables of different lengths. Therefore, a first scale groove 6 and a second scale groove 7 are provided on the first clamp arm 1 to determine the length of cable stripping from the front or top of the first clamp arm 1. In this way, according to actual needs, the length of cable stripping is selected first, and then the model of eyelet is selected, so that eyelets can be made quickly, and cable waste or re-stripping will not be caused by unreasonable stripping length. The second clamp arm 2 is provided with positioning grooves 8. There are multiple positioning grooves 8, and the width of the grooves 8 increases sequentially from the front end of the second clamp arm 2 to the rear. After the front ends of the first clamp arm 1 and the second clamp arm 2 are closed, a sheath 9 is fitted on the outside. In this utility model, the groove width of multiple positioning grooves 8 is set according to the different sizes of screws used by the electric actuator at the installation site, such as common sizes like M3, M4, and M5. The groove width of the multiple positioning grooves 8 corresponds to the diameter of the M3, M4, and M5 screws, respectively. When using, you can select as needed. After the copper wires inside the wiring are fixed by the first clamp arm 1 and the second clamp arm 2, eyelets of different sizes can be formed on the wiring by bending the copper wires at the corresponding size positioning grooves 8.

The protective rubber sleeves 10 can improve the anti-slip properties of the tool during use, and prevent wear and tear on the operator's hands, thereby improving the comfort and safety of use.

[0018] The multiple first scale grooves 6 and multiple second scale grooves 7 are positioned to match each other, and each of the multiple first scale grooves 6 and multiple second scale grooves 7 is provided with scale lines. By setting the scale lines in the first scale grooves 6 and multiple second scale grooves 7, the problem of easy wear and disappearance caused by setting the scale lines in the first clamp arm 1 can be avoided.

[0019] Both the first tooth surface 4 and the second tooth surface 5 are composed of multiple continuously arranged single teeth, and the cross-section of each single tooth is a triangular structure. By setting the first tooth surface 4 and the second tooth surface 5, the tool can strip the wires and stably clamp the copper wires in the wiring.
