Description

Technical Field

[0001] The utility model relates to the technical field of motor connection terminals, in particular to a connection terminal connected with an enameled wire. Background Art

[0002] The wiring terminals of the motor housing are interfaces for connecting the motor to an external power source or device, and are usually located on the side or top of the motor housing. The wiring terminals of the motor housing are usually made of conductive materials, such as copper or aluminum, and have good conductivity and corrosion resistance. The number and type of wiring terminals vary depending on the motor. When connecting, the wires on the motor are generally connected to the outside from the wiring terminals. In the prior art, the enameled wires in the motor are generally directly welded to the wiring terminals, and then pass through the insulating protective cover above the wiring terminals to connect to the adjacent wiring terminals. However, if this connection method is used, when the enameled wire is moved, it is easy to cause the enameled wire to be desoldered from the wiring terminal, thereby causing the motor to lose power. Utility Model Content

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect in the prior art that when the enameled wire is moved, it is easy to cause the enameled wire and the terminal to become desoldered, thereby causing power failure in the motor, thereby providing a terminal that can significantly reduce the probability of desoldering.

[0004] To this end, the utility model provides a wiring terminal connected to an enameled wire, comprising: a terminal body;

[0005] At least one slot is provided above the terminal body and allows the enameled wire to pass through the slot; a welding block is provided at one side of the terminal body and is used for welding with the enameled wire.

[0006] Furthermore: a plurality of extension blocks are arranged on the terminal body, the card slot is opened between two adjacent extension blocks, the two adjacent extension blocks are arranged in parallel and an "L"-shaped structure is arranged between the extension block and the terminal body.

[0007] Further: the clamping slot includes a first clamping slot and a second clamping slot, the first clamping slot is opened on the terminal body, the second clamping slot is located between two adjacent extension blocks, and the first clamping slot and the second clamping slot are arranged at intervals.

[0008] Furthermore: the welding block includes a bent end connected to the terminal body and a welding end for welding with the enameled wire, and the bent end and the welding end form a "7"-shaped structure.

[0009] Further: two first card slots are provided, and three second card slots are provided.

[0010] Further: the width of the first clamping slot is greater than the width of the second clamping slot.

[0011] Further: the welding block is located on a side of the terminal body facing away from the extension block.

[0012] The technical solution of the utility model has the following advantages:

[0013] 1. The utility model provides a wiring terminal connected to an enameled wire, wherein two or three slots are arranged on a terminal body, and after the enameled wire is wound thereon, the position of the enameled wire is fixed, and then the enameled wire is welded to a welding block. Since the enameled wire is fixed in the slot, the position of the enameled wire is not easy to move during use, thereby effectively avoiding the problem of desoldering and greatly reducing the probability of power failure of the motor.

[0014] 2. The utility model provides a terminal block connected to an enameled wire, wherein a plurality of extension blocks are arranged on a terminal body, and a slot is formed between two extension blocks. When the enameled wire is led out from an iron core, it is inserted into the slot, and then wound around the extension block, and then inserted into a second slot, and so on. After the winding is completed, the enameled wire is welded to the welding block to complete the power supply, so that the position of the enameled wire can be effectively fixed to avoid pulling of the enameled wire, which may cause desoldering between the enameled wire and the welding block.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Example

[0027] The present embodiment provides a wiring terminal connected to an enameled wire, comprising: a terminal body 1; at least one slot 2, which is opened above the terminal body 1 and allows the enameled wire to pass through the slot 2; and a welding block 3, which is arranged on one side of the terminal body 1 and is used for welding with the enameled wire.

[0028] The above specific improvements are: Figure 1 and Figure 2As shown, compared with the prior art, two or three slots 2 are provided on the terminal body 1. After the enameled wire is wound thereon, the position of the enameled wire is fixed, and then the enameled wire is welded to the welding block 3. Since the position of the enameled wire is fixed after being stuck in the slot 2, the position of the enameled wire is not easy to move during use, thereby effectively avoiding the problem of desoldering and greatly reducing the probability of power failure of the motor.

[0029] On the basis of the above embodiment: a plurality of extension blocks 4 are arranged on the terminal body 1, the slot 2 is opened between two adjacent extension blocks 4, the two adjacent extension blocks 4 are arranged in parallel and an "L"-shaped structure is arranged between the extension block 4 and the terminal body 1.

[0030] The above specific improvements are: Figure 2 and Figure 3 As shown, a plurality of extension blocks 4 are provided on the terminal body 1, and a slot 2 is formed between two extension blocks 4. When the enameled wire is led out from the core, it is inserted into the slot 2, and then wound around the extension block 4, and then inserted into the second slot 2, and so on. After the winding is completed, the enameled wire is welded to the welding block 3 to complete the power supply, so that the position of the enameled wire can be effectively fixed to avoid pulling of the enameled wire, which may cause desoldering between the enameled wire and the welding block 3.

[0031] On the basis of the above embodiment: the card slot 2 includes a first card slot 21 and a second card slot 22, the first card slot 21 is opened on the terminal body 1, the second card slot 22 is located between two adjacent extension blocks 4, and the first card slot 21 and the second card slot 22 are arranged at intervals.

[0032] The above specific improvements are: Figure 3 As shown, the wires wound on the motor housing are usually divided into hard wires and soft wires. According to different application scenarios and requirements, different sizes of enameled wires need to be selected. In order to make the terminal block adapt to enameled wires of different sizes, the slot 2 is divided into a first snap-in slot 21 and a second snap-in slot 22. The size of the first snap-in slot 21 is larger than the size of the second snap-in slot 22. When the motor needs to withstand greater tension and pressure, a larger enameled wire is required. The enameled wire needs to be clipped into the first snap-in slot 21 for winding. When the enameled wire needs to be frequently bent or moved, a smaller enameled wire can be used. The enameled wire is no longer wound in the first snap-in slot 21, but is wound in the smaller second snap-in slot 22. In this way, the terminal block can be suitable for enameled wires of different sizes at the same time, thereby improving the versatility of the terminal block.

[0033] On the basis of the above embodiment: the welding block 3 includes a bending end 31 connected to the terminal body 1 and a welding end 32 for welding with the enameled wire, and the bending end 31 and the welding end 32 form a "7"-shaped structure.

[0034] The above specific improvements are: Figure 4 As shown, the welding block 3 is integrally formed with the terminal body 1. During the processing, the terminal body 1 and the welding block 3 are first punched out, and then the welding block 3 is bent to form a bending end 31 and a welding end 32. The enameled wire is welded at the welding end 32, and the bending end 31 is located between the terminal body 1 and the welding end 32.

[0035] On the basis of the above embodiment: two first clamping slots 21 are provided, and three second clamping slots 22 are provided.

[0036] On the basis of the above embodiment: the width of the first clamping groove 21 is greater than the width of the second clamping groove 22 .

[0037] The above specific improvements are: Figure 3 As shown, the depth and width of the first clamping groove 21 are greater than the depth and width of the second clamping groove 22 , so that when the enameled wire cannot be clamped into the second clamping groove 22 , it can be clamped into the first clamping groove 21 .

[0038] On the basis of the above embodiment: the welding block 3 is located at a side of the terminal body 1 facing away from the extension block 4 .

[0039] The above specific improvement is: after the enameled wire is wound on the welding block 3, the enameled wire is introduced into the lower end, welded on the welding block 3, and then introduced into the outer insulating sheath.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
