On the contrary, these embodiments are provided so that the present disclosure will be comprehensive and complete, and will fully convey the scope of the present disclosure to those skilled in the art. In addition, the present disclosure is limited only by the scope of the claims.

[0020] The shapes, sizes, ratios, angles and numbers disclosed in the drawings for describing the embodiments of the present disclosure are only examples, and therefore the present disclosure is not limited to the details shown. Throughout this specification, the same reference numerals refer to the same elements. In the following description, when the detailed description of the relevant known functions or configurations is determined to be unnecessary to blur the focus of the present disclosure, the detailed description will be omitted. In the case of using "including", "having" and "comprising" described in this specification, other parts may be added unless "only" is used. Unless otherwise indicated, the terms in the singular may include plural forms.

[0021] When explaining an element, although not explicitly described, the element is understood to include a range of error.

[0022] When describing a positional relationship, for example, when the positional relationship is described as "on," "above," "below," and "adjacent to," unless "immediately" or "directly" is used, one or more parts may be arranged between two other parts.

[0023] When describing a time relationship, for example, when a time sequence is described as “after,” “subsequently,” “next,” and “before,” discontinuous cases may be included unless “just” or “directly” is used.

[0024] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from other elements. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present disclosure.

[0025] As those skilled in the art can fully understand, the features of the different embodiments of the present disclosure can be coupled or combined with each other in part or in whole, and can cooperate with each other in various ways and be driven technically. The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.

[0026] Reference Figures 1 to 3 The utility model discloses a fixture for terminal welding wire, including a fixture plate 1, on which a positioning groove 1 3 for placing a circuit board 2 and a positioning groove 2 5 for placing a power line 4 are provided, and a positioning plate 6 which can be moved by a guide mechanism and positions the welding end of the power line 4 at the welding position on the circuit board 2, and a clearance hole 20 is also provided on the bottom surface of the positioning groove 1 3 for avoiding components on the circuit board, and the positioning plate 6 and the positioning groove 1 3 and the positioning groove 2 5 are all on the same side of the fixture plate 1, and the position of the positioning groove 1 3 is lower than the position of the positioning groove 2 5, so In order to weld the power cord 4 above the circuit board 2, although the power cord 4 is initially positioned through the positioning groove 2 5, the positioning groove 2 5 makes it convenient for workers to manually place the power cord 4 in place, and also reduces the difficulty of subsequent positioning by the positioning plate 6, because the welding end needs to extend out of the positioning groove 2 5 and be located above the circuit board 2, and the power cord 4 is soft, so the position of the welding end is not accurate, and therefore the welding end needs to be accurately positioned through the positioning plate 6. After the positioning is completed, the power cord 4 can be pressed by the clamping mechanism on the jig plate 1 for welding.

[0027] As shown in the figure, the positioning plate 6 is provided with a line end positioning groove 7, and the line end positioning groove 7 is located at the side edge of the positioning plate 6. The welding end is stuck in the line end positioning groove 7 and pushed to the welding position above the circuit board 2 through the line end positioning groove 7, so as to position the left and right and length directions of the welding end. In the present application, there are two power lines 4, one end of the two power lines 4 is fixed side by side as a whole by rubber coating, and the other end is a welding end. Because there is a certain distance between the welding positions of the two power lines 4, the part between the two line end positioning grooves 7 constitutes a dividing rod 8. When the power line 4 is stuck in the line end positioning groove 7, the dividing rod 8 is also inserted between the two power lines 4 to separate them by a certain distance, and the distance is controlled by the width of the dividing rod 8.

[0028] As shown in the figure, the guiding mechanism includes a side plate 1 9 provided on one side of the jig plate 1 and a side plate 2 10 provided on the other side of the jig plate 1. A sliding hole and a sliding rod 11 cooperating with the sliding hole are provided in the jig plate 1. The side plate 1 9 and the side plate 2 10 are fixed to the corresponding ends of the sliding rod 11, so that the sliding rod 11, the side plate 1 9 and the side plate 2 10 constitute a frame that can slide on the jig plate 1, thereby guiding the positioning plate 6 to move along the surface of the jig plate 1.

[0029] As shown in the figure, a slot 12 is provided on the end face of the side panel 19, a limit seat 13 is provided on the fixture plate 1, and a ball screw 14 is provided in the limit seat 13. When the positioning plate 6 moves to a predetermined position, the ball of the ball screw 14 can be stuck in the slot 12 to fix the side panel 19, thereby also fixing the positioning plate 6. When the positioning plate 6 is in this position, the positioning plate 6 just positions the welding end at the welding position. The slot 12 is a V-shaped groove. If the side panel 10 is pulled hard, the ball can be retracted and disengaged from the slot 12 by squeezing the slot 12, thereby resetting the side panel 19. The ball screw 14 is a commonly used part purchased from outside. The ball is ejected by squeezing the spring in the screw. Its specific structure is not described in detail.

[0030] In order to facilitate hand-held operation, a hand-held frame 15 is provided on the fixture plate 1, so that the operator can hold the hand-held frame 15 and press the side plate 10 to move the positioning plate 6.

[0031] As shown in the figure, the clamping mechanism includes a clamp and a wire pressing plate 17 fixed on the clamp 16. By operating the clamp 16, the wire pressing plate 17 can be driven to rotate to clamp and fix the power cord 4. The clamp 16 is a conventional product purchased from outside, so the specific structure is not described in detail. As a further structure, a wire pressing groove 18 is provided on the jig plate 1, and the positioning groove 5 is located below the wire pressing groove 18 and is connected with the wire pressing groove 18. The wire pressing plate 17 is provided with a wire pressing convex strip that can be inserted into the wire pressing groove 18. This can ensure that the wire pressing plate 17 will not swing when clamping the power cord 4, thereby causing the power cord 4 to be inaccurately positioned.

[0032] The above is a detailed introduction to a terminal welding wire fixture provided by an embodiment of the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
