Description

A connection tool for wire connection Technical Field

[0001] The present invention relates to the technical field of wire processing, and in particular to a connecting tool for connecting wires. Background Art

[0002] In industrial production processes, it is often necessary to connect two wires (such as welding wires, iron wires, etc.), that is, to connect the ends of the two wires to form a longer wire. The current common method is generally manual welding, which involves welding the ends of two metal wires. However, this method is labor-intensive, and the handheld method makes it difficult to accurately connect the two metal wires. At the same time, for metal wires with a small radius, the method of aligning the ends and then welding cannot be used. Generally, the ends of the two wires need to have a certain overlap length, and then the welding is performed on the side of the wires. This method will prevent the center lines of the two metal wires from coinciding, resulting in misalignment problems, and the surface of the resulting long wire will be seriously uneven. Summary of the Invention

[0010] Furthermore, the connecting clamp further comprises a connecting clamping spring, which acts on the two connecting jaws and provides elastic force to drive the two connecting jaws to move to a closed state.

[0034] Referring to Figures 1 to 13, the present invention provides a connecting tool for wire connection, including a wire clamping mechanism and a connecting clamp 5, the wire clamping mechanism includes two wire positioning clamps 2, and a connecting operation space 4 is provided between the two wire 1 positioning clamps, the wire positioning clamps 2 can clamp the wire 1, and the ends of the wire 1 of the two wire positioning clamps 2 can extend into the connecting operation space 4, the connecting clamp 5 includes two oppositely arranged connecting jaws 51, the connecting jaws 51 include a clamping block 511, and the clamping block 511 is provided with a clamping strip groove 512, the two connecting jaws 51 can be separated from each other or closed, and when in the closed state, the clamping strip grooves 512 of the two connecting jaws 51 can clamp on the wire 1, and the connecting clamp 5 can extend into the connecting operation space 4.

[0035] The connection tooling of the present invention is used to connect the ends of two wires 1 to form an integral wire 1, wherein the wire 1 can be made of metal or plastic. When in use, the two wires 1 are first clamped in the two wire positioning fixtures 2 of the wire clamping mechanism, and the ends of the two wires 1 are both extended into the connection operation space 4, and the two have a certain overlap length, see Figure 10, then the ends of the two wires 1 are heated to soften but not melt, the two connecting jaws 51 of the connecting fixture 5 are separated and extended into the connection operation space 4, and then the two clamping blocks 511 are clamped on both sides of the ends of the two wires 1 respectively, and the two clamping blocks 511 squeeze the end positions of the wires 1, see Figure 1, so that the softened end positions of the two wires 1 merge with each other, thereby achieving connection, and the two wires 1 are located in the clamping strip grooves 512 of the clamping blocks 511 of the two connecting jaws 51 to remain stable, thereby being able to maintain good coaxiality. The connecting clamp 5 is kept in the closed state for a period of time. After the two wires 1 are cooled and connected, the connecting clamp 5 is separated and removed, see Figures 11, 12 and 13, and then the wires 1 are removed from the wire clamping mechanism.

[0036] The connecting tool of the present invention can conveniently connect two wires 1 and maintain good coaxiality to ensure the connection effect. It is applicable to wires 1 of various radius sizes. The connecting tool has a simple structure and is easy to use. Compared with the existing manual welding method, it is simple to operate and has a small labor load.

[0037] In this embodiment, referring to FIG1 , the cross section of the wire 1 is circular. As a preferred design, the cross section of the clamping strip groove 512 (the surface perpendicular to the extension direction of the clamping strip groove 512) is arc-shaped, and the radius of the clamping strip groove 512 is equal to the radius of the wire 1. Therefore, when the connecting clamp 5 clamps two wires 1, the clamping strip groove 512 can maintain a good fit with the wire 1, thereby stabilizing the position of the wire 1. Of course, the cross section of the wire 1 can be circular or other shapes, and the cross section of the clamping strip groove 512 can also be other shapes, as long as the above-mentioned clamping on the wire 1 can be achieved. In this embodiment, preferably, the clamping strip groove 512 extends along a straight line, that is, it is a straight groove, and of course it can also have a certain curvature.

[0038] When the connecting clamp 5 clamps two wires 1, since there is an overlapping part at the ends of the two wires 1, the amount of material here is relatively large. In order to ensure that the groove surface of the clamping strip groove 512 in the connecting clamp 5 can be in contact with the wires 1 without being affected by the overlapping part, see Figure 1. As a preferred design, in this embodiment, when the two connecting jaws 51 of the connecting clamp 5 are in a closed state, there is a gap between the edges of the clamping strip grooves 512 of the two, wherein the gap can be set along the entire length of the clamping strip groove 512, see Figure 9, that is, the two clamping strip grooves 512 do not form a complete cylindrical cavity, and the gap can also be set at the position in the middle of the clamping strip groove 512 corresponding to the overlapping part of the ends of the two wires 1. Therefore, when the connection fixture 5 is clamped on two wires 1, in addition to forming a cylindrical section in the two clamping strip grooves 512, the excess material is squeezed out from the gap between the edges of the two clamping strip grooves 512 to form a thin sheet-like extrusion portion 7, as shown in Figure 12. After the connection is completed, the surface of the wires 1 is processed to remove the extrusion portion 7.

[0039] In another embodiment, the connecting jaw 51 is provided with a connecting accommodating groove (not shown in the drawings) at the middle position of the length of the clamping strip groove 512. The cross-section of the connecting accommodating groove (the surface perpendicular to the extension direction of the clamping strip groove 512) is larger than the cross-section of the clamping strip groove 512. The connecting accommodating groove can be semi-cylindrical or hemispherical, and its radius is larger than the radius of the clamping strip groove 512. The specific length can be determined according to the necessary overlap length. When the connecting clamp 5 clamps two wires 1, the end overlap portion is located in the connecting accommodating groove. At this time, there can be no gap between the side edges of the connecting accommodating grooves in the two connecting jaws 51. The end overlap portion is squeezed and fused into one in the connecting accommodating groove, forming a connecting fusion portion 6 that is larger than the radius of the wire 1, see Figure 11. After the connection is completed, if it is necessary to ensure that the surface of the wire 1 is flat, the surface of the wire 1 can also be trimmed to trim the connecting fusion portion 6 to the size of the wire 1.

[0040] In another embodiment, the cross-section of the wire 1 is circular, the cross-section of the clamping strip groove 512 on the connecting clamp 51 is arc-shaped, and the radius of the clamping strip groove 512 is slightly larger than the radius of the wire. In this case, there may be no gap or a gap between the edges of the two clamping strip grooves 512. When the connecting clamp 5 clamps two wires 1, because the radius of the clamping strip groove 512 is larger than the wire 1, the overlapping portion of the end will form a cylindrical fusion section 8 with a radius slightly larger than the diameter of the wire 1 body in the connecting accommodating groove. When the radius of the fusion section 8 meets the wire tolerance, the connected wires 1 do not require surface finishing.

[0041] In this embodiment, referring to Figures 6 and 7 , as a preferred design, the connecting jaw 51 further includes a first finger plate 513 and a second finger plate 514 fixedly connected to the clamping block 511. A plurality of first finger plates 513 and a plurality of second finger plates 514 are provided on either side of the clamping strip groove 512. The first finger plates 513 and the second finger plates 514 in the same connecting jaw 51 are staggered. Furthermore, the first finger plates 513 in the two connecting jaws 51 are staggered, and the second finger plates 514 are also staggered. When the two connecting jaws 51 of the connecting clamp 5 are closed, referring to Figures 8 and 9 , the first finger plate 513 of one connecting jaw 51 extends into the gap on the side of the first finger plate 513 of the other connecting jaw 51, while the second finger plate 514 of the other connecting jaw 51 extends into the gap on the side of the second finger plate 514 of the other connecting jaw 51, ensuring smooth closing. Specifically, in this embodiment, three first finger plates 513 and three second finger plates 514 are provided in the connecting jaw 51. A gap exists between adjacent first finger plates 513 to accommodate the insertion of a first finger plate 513 on another connecting jaw 51. Similarly, a gap exists between adjacent second finger plates 514 to accommodate the insertion of a second finger plate 514 on another connecting jaw 51. The provision of the first finger plates 513 and the second finger plates 514 increases the gripping range of the connecting jaw 51, making operation more convenient. When clamping the wire 1, the wire 1 is within the range of the first finger plates 513 and the second finger plates 514 and, guided by the first finger plates 513 and the second finger plates 514, can easily and smoothly enter the clamping strip groove 512.

[0042] In this embodiment, referring to FIG1 , as a preferred design, the two connecting jaws 51 of the connecting clamp 5 are hinged and can rotate relative to each other to separate or close. The connecting clamp 5 also includes a connecting clamping spring 52, which can be a torsion spring. The connecting clamping spring 52 acts on the two connecting jaws 51 and provides elastic force to drive the two connecting jaws 51 to move to a closed state. Therefore, when the connecting clamp 5 clamps two wires 1, a stable clamping state is maintained by the connecting clamping spring 52, and there is no need to maintain a manual clamping operation, which is more convenient to use. The clamping block 511 of the connecting jaw 51 needs to be in direct contact with the heated wire 1, so the clamping block 511 is made of a material with a melting point higher than that of the wire 1 to avoid damage due to high-temperature melting. In other embodiments, the two connecting jaws 51 of the connecting clamp 51 can be separated or closed by linear movement or other methods.

[0043] In this embodiment, referring to Figures 4 and 5, as a preferred design, the wire positioning fixture 2 includes two wire positioning clamping flaps 21 arranged opposite to each other, the wire positioning clamping flaps 21 are provided with a positioning clamping plate 211, and the positioning clamping plate 211 is provided with a positioning strip groove 212. The two positioning clamping plates 211 on the wire positioning fixture 2 can be separated or closed with the movement of the wire positioning clamping flaps 21, and when in the closed state, the positioning strip grooves 212 of the two positioning clamping plates 211 can clamp on the wire 1 and fix the wire 1. Among them, the positioning strip groove 212 is preferably a semi-cylindrical surface, that is, the cross section of the positioning strip groove 212 is also an arc shape, and its radius is equal to the radius of the wire 1, so that it can be well clamped on the wire 1.

[0044] As a preferred design, the two wire positioning clamps 21 of the wire positioning clamp 2 are hinged and can rotate relative to each other so that the positioning clamping plates 211 of the two are separated or closed. The wire positioning clamp 2 also includes a positioning clamping spring 22, which can be a torsion spring. The positioning clamping spring 22 acts on the two wire positioning clamps 21 and provides elastic force to drive the two wire positioning clamps 21 to move to a closed state. Therefore, when the wire 1 is clamped in the wire positioning clamp 2, a stable clamping state is maintained by connecting the clamping spring 52, and there is no need to maintain a manual clamping operation, which is more convenient to use. In other embodiments, the two wire positioning clamps 21 of the wire positioning clamp 2 can be separated or closed by using methods such as linear movement.

[0045] In this embodiment, referring to Figure 1, as a preferred design, the wire clamping mechanism also includes a fixed plate 3, and the two wire positioning clamps 2 have a wire positioning clamping flap 21 fixed on the fixed plate 3, and the positioning strip grooves 212 of the two wire positioning clamping flaps 21 fixed to the fixed plate 3 remain coaxial. In this way, when the two wires 1 are clamped in the two wire positioning clamps 2 respectively, the parts located in the positioning strip grooves 212 remain collinear, thereby better ensuring that the two wires 1 have good coaxiality after being reconnected.

[0046] As can be seen from the above, the connecting tool of the present invention has the following beneficial effects:

[0047] 1. It can easily connect two wires 1 and maintain good coaxiality to ensure the connection effect. It is applicable to wires 1 of various radius sizes.

[0048] 2. The connection tooling has a simple structure and is easy to use, and has a smaller labor load than the existing manual welding method.

[0049] 3. The wire clamping mechanism can stably clamp the two wires 1 and accurately locate the positions of the two wires 1 after clamping, ensuring that the two wires 1 can maintain good coaxiality during subsequent connection; the connecting clamp 5 can stably clamp on the wire 1 without manual maintenance.

[0050] In summary, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0051] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
