Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of wire welding, especially relates to a wire welding fixture. BACKGROUND

[0002] In the field of electronic device manufacturing and related wiring, the connection and assembly process of wires are crucial. Currently, there are various types of wires in the industry, among which the one-core-one-ground wire and the conventional flat wire (two-core-two-ground) exhibit significant differences in actual application.

[0003] The one-core-one-ground wire has a unique shape, which is close to a circular structure. This shape causes the front end of the wire to easily rotate during operation. This characteristic causes many inconveniences in the actual wiring and installation process. To solve this problem, the current common practice is to paste a masking tape on the wire to fix the position of the wire and ensure its relative stability during subsequent operations. However, this method has obvious drawbacks. Each time the wire is placed, the masking tape must be re-pasted, which not only consumes a lot of time and labor but also increases the complexity of the operation steps, greatly reducing work efficiency.

[0004] At the same time, the one-core-one-ground wire and the conventional flat wire also have significant differences in size specifications. Specifically, the outer diameter of the one-core-one-ground wire is much smaller than that of the conventional flat wire. This size difference causes serious problems in the welding process. Due to the inconsistent outer diameters of the two types of wires, the existing wire welding fixture only has a single specification wire slot, which cannot combine them for welding operation. They can only be welded separately. This undoubtedly greatly increases the welding workload, lengthens the entire production cycle, and leads to low welding efficiency, which further affects the overall production schedule and cost control.

[0005] In summary, the one-core-one-ground wire and the conventional flat wire have a series of problems caused by differences in shape and size during use, which seriously restricts the improvement of production efficiency and quality, and an innovative solution is urgently needed to improve this situation.

DETAILED DESCRIPTION

[0039] The utility model will be further explained in combination with the drawing and specific embodiment.

[0040] The contents not described in detail in the specification belong to the prior art known to those skilled in the art. In the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0041] As Figures 1 to 12As shown, the wire welding jig provided in the embodiment is a signal cable, which comprises a first wire clamping seat 1 and a second wire clamping seat 2. The first wire clamping seat 1 is detachably connected to the second wire clamping seat 2. The first wire clamping seat 1 has a profiling groove 111, and the second wire clamping seat 2 has a placement groove 241. The profiling groove 111 is located above the placement groove 241 and is arranged obliquely relative to the placement groove 241. The second wire clamping seat 2 has a placement groove 241 for placing a conventional flat wire (two-core two-ground), and the first wire clamping seat 1 has a profiling groove 111 for placing a one-core one-ground wire. The profiling groove 111 on the first wire clamping seat 1 is adapted to the one-core one-ground wire, which can precisely prevent the one-core one-ground wire from rotating during operation, greatly improving the accuracy and stability of the operation. Compared with the previous method of fixing the position of the wire by using masking paper, this foolproof positioning function does not require additional materials and manual pasting operations, which reduces material costs and labor investment. At the same time, it avoids the risk of wire displacement caused by insecure or inaccurate placement of masking paper, providing a stable and reliable precondition for subsequent welding procedures. Since the first wire clamping seat 1 and the second wire clamping seat 2 are designed in a separated manner, the operator can perform wire arranging and separating operations on the one-core one-ground wire on the first wire clamping seat 1 and the conventional flat wire (two-core two-ground) on the second wire clamping seat 2 before welding. The advantage of this separated operation is that different types of wire handling work can be carried out in parallel, avoiding interference between different wires and improving the efficiency of the preliminary preparation work. After the wire arranging and separating operations are completed, the first wire clamping seat 1 is directly installed on the second wire clamping seat 2, which is simple and fast, greatly shortening the time interval from wire preparation to welding process. Moreover, since the wire arranging and separating operations are completed in advance on the respective wire clamping seats, different types of wires can be welded simultaneously, which significantly reduces the total welding time compared to the traditional separate welding method, greatly improves the welding efficiency, and effectively shortens the entire production cycle. The separated wire clamping seat design allows independent wire arranging and separating operations in the respective grooves, which helps to better organize and position the wires, ensuring that each wire is in the correct position and reducing the likelihood of poor welding caused by wire confusion and mispositioning.

[0042] The first clamp seat 1 comprises a first base 11, a first cover 12 and a first lock 13. The middle part of the first base 11 is provided with a plurality of profiled grooves 111. The right side of the first base 11 is hingedly connected with the first cover 12. The first cover 12 is located above the profiled grooves 111. The left side of the first base 11 is provided with the first lock 13. The first lock 13 is matched with the first cover 12. When winding the wire, the first cover 12 is opened. Then, the core and ground wire is placed in each profiled groove 111. Then, the first cover 12 is closed. After the first cover 12 is closed, the first lock 13 is used to press the first cover 12 to lock the first cover 12. The first cover 12 and the profiled grooves 111 are used to fix and limit the core and ground wire, so that the position of the core and ground wire cannot be deviated.

[0043] The first cover 12 comprises a first cover plate 121 and a first soft pad 122. The bottom of the first cover plate 121 is provided with the first soft pad 122. The first soft pad 122 is located above the profiled grooves 111. The first soft pad 122 is used to limit the wire and avoid damaging the wire.

[0044] The first lock 13 comprises a first rotating arm 131, a first torsional spring shaft 132 and a first pressing arm 133. The bottom end of the first rotating arm 131 is hingedly connected with the left side of the first base 11.

The first pressing arm 133 comprises a rotating part 1331 and a pressing part 1332 which are connected with each other. When the first pressing arm 133 presses the first cover plate 121, the rotating part 1331 and the pressing part 1332 press the top of the first cover plate 121. When unlocking, the first pressing arm 133 is pulled upwards and then pushed to the left and downwards, so that the first pressing arm 133 is separated from the first cover plate 121, and the first cover plate 121 is opened. Under the action of the first torsional spring shaft 132, after the first pressing arm 133 is released, the first pressing arm 133 in the unlocking state swings upwards. When locking, after the first cover plate 121 is closed, the first pressing arm 133 which swings upwards is pulled to the left, and then the first pressing arm 133 is pulled to the right and upwards. At this time, the first pressing arm 133 is in a vertical state relative to the first cover plate 121. Then, the first pressing arm 133 is released. Under the action of the first torsional spring shaft 132, the first pressing arm 133 swings to the right and downwards until the rotating part 1331 and the pressing part 1332 press the top of the first cover plate 121 to lock and fix the first cover plate 121. In this way, the locking and unlocking operations of the first cover plate 121 can be realized only by simple pulling operation, and the operation is simple.

[0045] The one end of the first cover plate 121 has a concave groove 1211 for the first rotating arm 131 to extend into, and the bottom of the pressing part 1332 has an inclined surface 13321. The inclined surface 13321 is arranged to facilitate the fingers to extend into and press the first pressing arm 133.

[0046] The second wire clamping seat 2 comprises a second base 21, a second cover 22, a second lock 23, and a placement plate 24. The top of the placement plate 24 has a plurality of placement grooves 241. The placement plate 24 is detachably installed on the second base 21. The second cover 22 is hingedly connected to the right side of the second base 21 and is located above the placement grooves 241. The second lock 23 is arranged on the left side of the second base 21 and cooperates with the second cover 22. When arranging the wire, the second cover 22 is opened, the flat wire is placed in each placement groove 241, the second cover 22 is closed, and the second cover 22 is locked by the second lock 23 after being closed. The placement plate 24 is detachably connected to the second base 21 by bolts. The placement plate 24 can be replaced according to the actual use requirements to adapt to wires of different shapes and improve the versatility.

[0047] The second cover 22 comprises a second cover plate 221 and a second soft pad 222. The second cover plate 221 has a first cover section 2211 and a second cover section 2212 arranged at intervals along the length direction of the placement grooves 241. The first cover section 2211 is located in front of the second cover section 2212. The bottom of each of the first cover section 2211 and the second cover section 2212 has a second soft pad 222, and the second soft pad 222 is located above the placement grooves 241. The first cover section 2211 and the second cover section 2212 limit the front and rear parts of the flat wire, respectively. The second soft pad 222 not only limits the wire but also avoids damaging the wire.

[0048] The bottom of the first wire clamping seat 1 has a clamping groove 112 for clamping the first cover section 2211. Specifically, the clamping groove 112 is arranged on the bottom of the first base 11. The clamping groove 112 and the first cover section 2211 are clamped to detachably connect the first wire clamping seat 1 and the second wire clamping seat 2.

[0049] The second locking part 23 comprises a second torsion spring shaft 231, a second pressing arm 232, a second rotating arm 233 and a swing lever 234, the right end of the first cover section 2211 is hinged to the second base 21, the left end of the first cover section 2211 has an extension 22111, the second base 21 is hinged to the second pressing arm 232 for pressing the extension 22111 through the second torsion spring shaft, the second base 21 at the rear side of the second pressing arm 232 is hinged to the second rotating arm 233, the front end of the second rotating arm 233 is hinged to the swing lever 234, and the front end of the swing lever 234 is hinged to the rear end of the second pressing arm 232. When unlocking, the swing lever 234 is pried upward, so that the front end of the second rotating arm 233 moves upward, the rear end of the second pressing arm 232 moves downward, and the front end of the second pressing arm 232 swings upward and backward away from the first cover section 2211, so that the second cover plate 221 can be opened. After the swing lever 234 is released, the front end of the second pressing arm 232 swings downward and resets under the action of the second torsion spring shaft 231. When closing the second cover plate 221, the swing lever 234 is first pried upward, so that the front end of the second pressing arm 232 swings upward and backward to make room for the second cover plate 221, and after the second cover plate 221 is closed, the swing lever 234 is released, and the front end of the second pressing arm 232 swings downward to press the second cover plate 221 under the action of the second torsion spring shaft 231. In this way, only a simple prying action is needed to lock and unlock the second cover plate 221, and the operation is simple.
