Swift welding reason line tool

Technical Field

The utility model relates to a quick welding wire arranging jig.

Background

In the known high-speed data cable with the function of multi-channel signal transmission in the field of communication industry, the wire pairs corresponding to the signal channels are usually welded on a circuit board with a connecting golden finger inside a head connector. The heads of these wire pairs are typically subjected to a skiving and slitting of the inner aluminum foil and insulating sheath to draw out a plurality of side-by-side distributed soldered conductors for soldering with predetermined pads on the circuit board. Functionally, these weld conductors are typically comprised of a plurality of core conductors encased in an insulating jacket for signal transmission, and a plurality of ground conductors connected to an aluminum foil to carry a ground function to ensure stable signal transmission.

In the production design of the connector, in order to prevent signal crosstalk between the multi-channel wire pairs, the bonding pad groups of the wire pairs correspondingly soldered on the circuit board are often distributed at intervals laterally on the circuit board. For a single bonding pad group, in order to prevent interference between the inner conductors of the corresponding wire pairs, each bonding pad is not closely adhered to the inner conductor, and a certain interval is required, so that each bonding pad cannot be accurately aligned with the original side-by-side bonding conductors at the front ends of the wire pairs in actual bonding production, and the bonding pad positions can be adapted only by a worker through stirring and adjusting the gaps of the bonding conductors, namely, the bonding conductors of the wire pairs and the bonding pads of the bonding pad group on the circuit board are ensured to be aligned through wire arrangement.

However, the manual wire arrangement is very tedious and difficult to actually operate, and multiple wire pairs are often welded on the circuit board of a single connector, so that when the welding amount is large, the labor intensity of workers is increased, but the efficiency is very low. In addition, since the welding conductors are tiny and difficult to grasp, the concentration of the spirit of workers is high, and the welding quality is reduced due to long time and easy fatigue and error. For example, when the soldering conductor is not in place, it does not correspond to the middle position of the soldering pad, but is close to the edge, so that although soldering can be completed, the contact reliability of the soldering conductor and the soldering conductor is not high, and the signal transmission stability of the final high-speed data cable product is reduced.

The design can prevent the components on the bottom surface of the circuit board from being damaged due to compression.

6. In the design of the utility model, the groove width of the wire arranging groove is larger than the diameter of the welding conductor, so as to prevent the welding conductor from being extruded with the groove walls at the two sides of the wire arranging groove, and further prevent the welding conductor from being carried by the wire arranging block when the turnover plate is pulled up, thereby disturbing the existing alignment with the bonding pad.

As shown in fig. 5, namely, a circuit board 2 in the connector for a high-speed data cable in this embodiment is rectangular, a gold finger is inserted into the top of one surface of the circuit board, four bonding pad groups are transversely arranged at intervals in the middle of the circuit board, and each bonding pad group is composed of four bonding pads 4 distributed in a side-by-side gap mode. And positioning concave portions 201 are provided on the left and right sides of the wiring board 2, respectively. The structure of the single wire pair 1 is shown in fig. 6, four side-by-side welding conductors 3 are led out from the head of the wire pair 1, wherein the middle two welding conductors 3 are core wire conductors for signal transmission, the outer two welding conductors 3 are grounding conductors which bear the grounding function to ensure stable signal transmission, and the welding conductors 3 are copper wires. As shown in fig. 7, the wire pairs 1 are finally soldered to the wiring board 2, and the soldering conductors 3 of each wire pair 1 are connected in one-to-one correspondence with the pads 4 in the corresponding pad group.

Referring to fig. 1 to 4, the jig for quick welding and wire arranging provided in this embodiment is composed of a fixing frame 5 for fixing a circuit board 2, a turnover plate 6 with a rear end hinged to the fixing frame 5 and capable of opening and closing relative to the fixing frame 5, and four wire arranging blocks 7 fixed at the front end of the turnover plate 6 and corresponding to the positions of bonding pad groups on the circuit board 2 one by one.

Four wire arranging grooves 701 which are in one-to-one correspondence with the positions of the bonding pads 4 in the bonding pad group are arranged at the bottom of each wire arranging block 7 in parallel, and the front end surface of each wire arranging groove 701 is provided with a corresponding opening 701a for inserting a welding conductor 3 corresponding to the head of the wire pair 1; the bottom of each wire management block 7 may be attached to the wiring board 2 by flipping the flipping plate 6 such that the wire management grooves 701 of each wire management block 7 are vertically aligned with each pad 4 in the corresponding pad group.

And further referring to fig. 1 to 4, the wire arranging block 7 is provided with a bevel 702 on the peripheral edge (top edge and left and right edges) of each of the openings 701a for guiding the soldering conductors 3 to slide into the wire arranging groove 701. The inclined part 702 is convenient for the welding conductor 3 to be automatically guided and slide into the wire arranging groove 701 when pushing to the opening 701a, thereby avoiding the welding conductor 3 from being blocked by the periphery of the opening 701a and being manually stirred, and further simplifying the wire arranging operation.

In this embodiment, the fixing frame 5 is a rectangular frame, and its length is longer than that of the circuit board 2 shown in fig. 5, so that the circuit board 2 shown in fig. 5 with the same group of multiple types and different lengths with the same width can be actually installed, and the compatibility is very strong.

The practical working principle of the utility model for the wire arrangement of the circuit board shown in fig. 5 and the wire pair 1 welding shown in fig. 6 is as follows:

Initially, the flip plate 6 on the fixing frame 5 is in an open state, the circuit board 2 to be soldered is loaded into the fixing frame 5 by a worker, and positioning is performed by the positioning convex portion 501 on the fixing frame 5 being engaged with the positioning concave portion 201 on the circuit board 2.

The worker then turns the turn plate 6 to drive the bottoms of the wire management blocks 7 on the turn plate 6 to be attached to the circuit board 2, so that the wire management grooves 701 of the wire management blocks 7 are vertically aligned with the pads 4 in the corresponding pad group.

Then, the worker pushes each wire pair 1 against the surface of the wiring board 2 toward the corresponding wire arranging block 7 as shown in fig. 3 until the head of the wire pair 1 contacts the front end surface of the wire arranging block 7 as shown in fig. 4. In this process, after the bonding wires 3 led out from the heads of the wire pairs 1 contact the openings 701a on the wire arranging block 7, the bonding wires are guided by the inclined portions 702 along the peripheries of the openings 701a to slide into the corresponding wire arranging grooves 701, so that the bonding wires are completely aligned with the bonding pads 4 under the wire arranging grooves 701.

After finishing the wire arrangement alignment operation of all the wire pairs 1 and the corresponding bonding pad groups, the worker opens the turnover plate 6, so that each wire arrangement block 7 is separated from the surface of the circuit board 2, and then a subsequent welding effect can be implemented, and the welding conductors 3 led out from the heads of each wire pair 1 are welded to the bonding pad 4 where the wire arrangement block is positioned, as shown in fig. 7.
