Abstract
Description
Technical Field
[0001] The utility model relates to the field of terminal production, in particular to a motor terminal. Background Art
[0002] The prior art application number is: CN201720716651.X. A Chinese patent discloses a wiring terminal, including a terminal body and a locking nut integrally arranged with the terminal body. It solves the problem of eliminating the step of taking the locking nut during the grounding process of the iron shell motor, reduces the operation difficulty, reduces the operation time, and improves production efficiency.
[0003] For this reason, the utility model improves it, improves the firmness of the connection between the ground wire and the wiring terminal, increases the contact area, improves the working efficiency, and is convenient for replacement. Utility Model Content
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A motor terminal comprises a terminal made of a metal bolt, wherein a groove is provided at the middle of the top of the screw head of the metal bolt, the stud of the metal bolt is hollow inside and provided with an internal thread, and a compression gasket is fixedly connected in the groove by a hexagonal bolt;
[0006] The outer surface of the hexagonal bolt is threadedly connected to the inner surface of the stud of the metal bolt;
[0007] A notch connected to the groove is also provided on the top of the metal bolt. The metal bolt is threadedly connected to the ground wire reserved hole of the motor, and then the ground wire is inserted through the notch, and the hexagonal bolt is tightened so that the compression gasket squeezes the ground wire and fits tightly against the groove, so as to improve work efficiency, prevent falling off, and facilitate disassembly. The metal bolt can be processed with discarded bolts to save costs.
[0008] Furthermore, a pressure block is fixedly connected to the top of the clamping gasket at the position of the notch, and anti-slip serrations are provided on the side of the pressure block opposite to the bottom of the notch. A cross slot is provided on the top of the hexagonal bolt to prevent the grounding wire from shifting. The hexagonal bolt can be rotated by using a plum blossom screwdriver in conjunction with the cross slot to avoid obstruction by the pressure block, which is not suitable for socket tools.
[0009] Furthermore, an insulating sleeve is provided on the outer surface of the screw head of the metal bolt to protect the metal bolt.
[0010] Working principle and beneficial effects: By threading the metal bolt with the ground wire reserved hole of the motor, then inserting the ground wire through the gap, and tightening the hexagonal bolt so that the compression gasket squeezes the ground wire and fits tightly against the groove, it can improve work efficiency, prevent it from falling off, and facilitate disassembly. The metal bolt can be processed with discarded bolts to save costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention can be better understood according to the following embodiments.
[0015] The structures, proportions, sizes, etc. illustrated in the drawings of the specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "front", "back", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.
[0016] like Figure 1-2 As shown, a motor terminal comprises a terminal made of a metal bolt 1, a groove 2 is provided at the middle position of the top of the screw head of the metal bolt 1, the inside of the stud of the metal bolt 1 is hollow and provided with an internal thread, and a compression gasket 4 is fixedly connected in the groove 2 by a hexagonal bolt 3;
[0017] The outer surface of the hexagonal bolt 3 is threadedly connected to the inner surface of the stud of the metal bolt 1;
[0018] A notch 5 connected to the groove 2 is also provided on the top of the metal bolt 1. The metal bolt is threadedly connected to the ground wire reserved hole of the motor, and then the ground wire is inserted through the notch, and the hexagonal bolt is tightened so that the compression gasket squeezes the ground wire and fits tightly against the groove, so as to improve work efficiency, prevent falling off, and facilitate disassembly. The metal bolt can be processed with discarded bolts to save costs.
[0019] Among them, the top of the clamping gasket 4 is located at the position of the notch 5 and is fixedly connected with a pressure block 6. The pressure block 6 is provided with anti-slip serrations on the side opposite to the bottom of the notch 5. A cross slot is provided on the top of the hexagonal bolt 3 to prevent the grounding wire from shifting. The hexagonal bolt can be rotated by a plum blossom screwdriver in combination with the cross slot to avoid obstruction by the pressure block, and a socket tool is not suitable.
[0020] The outer surface of the screw head of the metal bolt 1 is also covered with an insulating sleeve 7 to protect the metal bolt.
