[0033] In the utility model, unless otherwise explicitly specified and limited, the terms "connection", "fixing" and the like should be understood broadly, for example, "connection" can be fixed connection, or detachable connection, or integral, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.

[0034] In addition, the technical schemes of various embodiments of the utility model can be combined with each other, but it must be based on the fact that those skilled in the art can realize it. When the combination of technical schemes appears contradictory or unachievable, it should be considered that the combination of technical schemes does not exist and is not within the scope of protection of the utility model.

[0035] Embodiment 1

[0036] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the embodiment provides a double-sided wire pressing tool for pressing and forming the square winding 8 and leading out the wires at both ends.

[0037] The crimping fixture mainly consists of a base and a cover plate that covers the base.

[0038] The base includes a base plate 10, on which a central flat portion 4 and inclined portions 11 located on both sides of the central flat portion 4 are provided. The central flat portion 4 has several fixing grooves 12 along its length direction for accommodating the main body of the winding 8.

[0039] The cover plate comprises multiple relatively rotatable segments, as in this preferred embodiment, such as... Figure 3 As shown, the cover plate includes a first segment 1, a second segment 2 and a third segment 3, wherein the first segment 1 and the second segment 2 are hinged together so that they can rotate relative to each other; the first segment 1 and the third segment 3 are independently hinged to the base plate 10.

[0040] Therefore, the cover plate can be opened and closed at multiple angles through various hinges, making it easy to put in and take out the winding 8.

[0041] Understandably, the number of segments is not limited to three; depending on the required winding length, two or more segments can be set.

[0042] like Figure 2 As shown, the inclined part 11 is provided with a first positioning plate 6 and a second positioning plate 7.

[0043] The first positioning plate 6 and the second positioning plate 7 are connected to each other (e.g., by welding or integral molding) to form a structure with an inner guide slope.

[0044] This embodiment also includes a wire lead-out structure. Specifically, a wire lead-out structure is provided on the third segment 3, and the wire lead-out structure is formed in the wire passage gap between the third segment 3 and the inclined portion 11.

[0045] Those skilled in the art will understand that the wire lead-out structure can be an actively opened hole or slot, or a gap naturally formed by the dimensional matching between components. Its core function is to provide a lead-out channel for the compressed wire.

[0046] The gap is formed by making the width of the third segment 3 smaller than the width of its corresponding inclined portion 11.

[0047] When the cover is closed, a longitudinally extending gap, namely the wire passage gap, is naturally formed between the inner edge of the third segment 3 and the second positioning plate 7 of the inclined part 11. The end wire of the winding 8 can be easily led out through this gap without being completely crushed by the cover, which facilitates subsequent operations.

[0048] The conductor lead-out structure also includes a wire passage groove 5 that is directly opened on the third section 3 plate, through which the conductor can pass directly out.

[0049] Based on the above design, the two ends of the winding 8 can be respectively led out from the wire passing gap and the wire passing groove 5 without interfering with each other.

[0050] In order to realize the compression of the winding 8, a detachable positioning member is arranged between the cover plate and the middle flat part 4.

[0051] The positioning member is a screw rod 9 which penetrates through the cover plate and cooperates with the base. Specifically, a through hole is arranged on the second segment 2, and a threaded hole is arranged at the corresponding position of the middle flat part 4. The screw rod 9 penetrates through the through hole and is screwed into the threaded hole. When the cover plate is closed, the screw rod 9 is tightened to force the second segment 2 to press downward, thereby preventing the main body of the winding 8 placed in the wire groove below from moving or bouncing up.

[0052] The working process is as follows: Figure 5 and Figure 6 First, loosen the screw rod 9 of the positioning member and open the cover plate. Then, place the main body of the winding 8 into the wire groove of the middle flat part 4, and place the two ends of the winding 8 above the inclined surfaces of the left and right inclined parts 11 respectively. Then, close the cover plate, at this time the first segment 1 and the third segment 3 press the ends of the winding 8 from both sides respectively, and the second segment 2 presses the main body of the winding 8. Finally, tighten the screw rod 9 of the positioning member to complete the fixation. The wires at both ends of the winding 8 can be respectively led out from the wire passing gap and the wire passing groove 5 on the third segment 3.

[0053] Embodiment 2

[0054] This embodiment provides another double-sided wire pressing tool, as shown in Figure 7 , Figure 8 and Figure 9 The difference between this embodiment and embodiment 1 mainly lies in the hinge way of the cover plate. In this embodiment, the features such as the base plate 10, the first positioning plate 6 and the second positioning plate 7 on the inclined part 11, the wire leading-out structure (such as the wire passing gap or the wire passing groove 5), and the positioning member (screw rod 9) can be referred to the corresponding description of embodiment 1.

[0055] In this embodiment, the cover plate also includes the first segment 1, the second segment 2 and the third segment 3. The difference is that the three segments are sequentially connected by hinges: that is, the first segment 1 is connected with the second segment 2 by a hinge, and the second segment 2 is connected with the third segment 3 by a hinge. The whole cover plate is connected with the base through only one hinge, and the hinge connects the end of the first segment 1 with one side of the base plate 10.

[0056] Since the cover plate has only one fixed hinge point, it can be flipped to one side as a whole when opened, and the first segment 1, the second segment 2 and the third segment 3 are sequentially closed to the base, thereby pressing the winding 8 into the required shape.

[0057] The foregoing description illustrates and describes the preferred embodiments of this application only, and it is understood that the application is not limited to the disclosed embodiments but is to be accorded the full scope of the claims appended hereto, and equivalents thereof.
