Description
Technical Field
[0001] The utility model belongs to the technical field of circuit components, and particularly relates to a multi-wire paralleling device. Background Art
[0002] Connecting wires together is one of the more common steps in decoration or wiring. For example, when wiring in a building, multiple wires need to be passed through the wire tube pre-buried in the wall. The usual method is to first insert a traction wire with a certain rigidity into the wire tube, and then wrap the ends of each wire together and connect them with the traction wire. Pull one end of the traction wire to drive the wire into the wire tube. When connecting the wires together, the insulation skin of the wire ends needs to be removed, and then with one wire as the center, the other wires are wrapped around the center wire. The effect of stripping and the tightness of the winding will affect the efficiency of the wiring. For example, when the tightness of the winding is poor, it will cause the wire to fall behind during the threading process, thereby affecting the work progress. In addition, poor tightness cannot meet the required standards for wiring, affecting the quality of wiring.
[0003] Although the existing wire winder can strip the wires and wind them together, the winding effect of this wire winder is not good, especially when winding multiple wires into the same wire, it is more troublesome, the appearance of the wound wires is not neat, the wound coils are not tight, and it is difficult to meet the national standards. In addition, it is time-consuming and labor-intensive to manually strip the wound wires, and it will cause damage to the fingers of the staff. Utility Model Content

[0025] Below, the utility model is further described in conjunction with the accompanying drawings.
[0026] A wire tie-in device for winding multiple wires comprises a wire bundle; a wire collecting cavity is arranged at the top of the wire bundle, and at least one cutting knife opening is arranged on the wall of the wire collecting cavity; and the inner diameter of the wire collecting cavity is greater than or equal to the sum of the diameter of the wound wire core conductor and twice the diameter of the winding wire core conductor.

[0028] Furthermore, a notch is provided on the wire collection ring, and the notch is directly opposite to and connected to the cutter opening.
[0029] Furthermore, a cutting edge is provided on one side of the cutting knife opening.
[0030] Furthermore, the cutting edge is located at the end portion of the cutting knife opening.
[0031] Furthermore, there are two cutter openings arranged in a straight line at the top of the cable drum, or there are three cutter openings arranged in a Y shape at the top of the cable drum, or there are four cutter openings arranged in a cross shape at the top of the cable drum.
[0032] Furthermore, the diameter of the wire collection ring is larger than the diameter of the wire bundle; the inner diameter of the wire passing hole gradually decreases from top to bottom and smoothly transitions to form a conical pit.
[0033] Furthermore, the outer wall of the end of the cable bundle barrel is provided with a hexagonal section and a threaded section, wherein the threaded section is located between the hexagonal section and the cable collection cavity.
[0034] Furthermore, the diameter of the threaded segment is greater than the diameter of the circumscribed circle of the hexagonal segment.
[0035] Furthermore, the cutter opening is located on the tangent line of the wire collecting cavity; and in the case of at least two cutter openings, the cutter openings are rotationally symmetrical.
[0036] The following is a more specific embodiment:
[0037] Reference Figure 1 and Figure 2 In this embodiment, a wire collecting cavity is provided at the top of the wire bundle barrel, and two cutting knife openings are provided on the wall of the wire collecting cavity; and the inner diameter of the wire collecting cavity is equal to the sum of the diameter of the wound wire core conductor and twice the diameter of the wound wire conductor.
[0038] When the winding wire is relatively thick, a certain amount of space will be left when it is wrapped around the wound wire, and the winding wire cannot be tightly attached to the wound wire. It is necessary to leave a certain amount of space in the wire collecting cavity. The inner diameter of the wire collecting cavity should be slightly larger than the sum of the diameter of the core conductor of the wound wire and twice the diameter of the winding wire conductor; to facilitate the winding of the winding wire on the wound wire.
[0039] A wire collecting ring is provided on the top of the cable bundle, and the wire passing hole and the wire collecting cavity of the wire collecting ring are located on the same central axis and are connected. A notch is provided on the wire collecting ring, and the notch is directly opposite to and connected to the cutter opening. A wire cutting blade is provided on one side of the cutter opening. The wire cutting blade is located at the end of the cutter opening. The notch can be regarded as a part of the cutter opening, which is convenient for inserting the wire winding. If there is no notch, the wire winding can also pass through the wire passing hole in the middle of the wire collecting ring and pass through the cutter opening, and the insulation skin is cut off by the wire cutting blade.
[0040] The diameter of the wire collection ring is larger than the diameter of the wire bundle; the inner diameter of the wire hole gradually decreases from top to bottom and smoothly transitions to form a conical pit; the conical pit can facilitate the insertion of the winding wire and the wound wire.
[0041] This example uses two opposite cutting openings, which are arranged in a straight line; it is also possible to have three cutting openings, which are arranged in a Y shape at the top of the cable barrel, or to have four cutting openings, which are arranged in a cross shape at the top of the cable barrel. Figures 3 to 6 In this embodiment, when there is one cutter opening, the cutter opening extends to one side along its tangent line; when there are two to four cutter openings, the cutter openings are rotationally symmetrical about the center of the cable bundle.
[0042] The use method and principle of this embodiment are as follows: when in use, firstly, the wound wire is passed through the wire hole and the wire collection cavity into the wire hole of the wire bundle barrel in a straight line; the wound wire is put into the wire cutting opening from the wire hole and aligned with the wire cutting blade; a driving device (manual rotation or motor rotation) is connected to the hexagon or thread of the wire bundle barrel to drive the wire bundle barrel to rotate around its own central axis, at which time the wire cutting blade peels off the insulation of the wound wire and winds it around the wound wire through the rotation of the wire bundle barrel. The core conductor of the wire is generally in the form of a cylinder, and the core conductors of the two wires will be squeezed by the inner wall of the wire collection cavity and wound side by side on the core conductor of the wound wire;
[0043] Principle of removing the insulation of the entangled wire: During the wire winding process, since the inner diameter of the wire collecting cavity is equal to the sum of the diameter of the core conductor of the entangled wire and twice the diameter of the winding core conductor, only the entangled core conductor and the core conductor of the winding wire can exist inside the wire collecting cavity; since the insulation material is easier to damage than the core conductor, the insulation of the entangled wire will be squeezed and cut by the winding core conductor, and a ring-shaped opening will be cut out of the insulation of the entangled wire and as the winding core conductor is wound, the insulation of the entangled wire will be pushed down backwards.
