BACKGROUND OF THE INVENTION Field of the Invention The present invention generally relates to a solderless twist of a wire connector and a method of manufacturing the same. More specifically, the present invention relates to a method of reducing contact electrical resistance by crimping a connection end of a wire in one operation. At the same time, a shell for manufacturing a twisted wire that encapsulates the wire connection in the wire connector so as to reduce the contact electrical resistance by crimping the wire connection end in the crimp and to encapsulate the wire connection end in the crimp. The present invention relates to the manufacture of twisted wire that encapsulates the wire connection in the wire connector while fixing the conventional twisted wire in the wire connector.

By twisting the cap on the wire, the technical idea of twisted wire connector connecting two or more wires has a long history in the art.

Twisted wires of a wire connector are well known in the art and generally constitute an outer housing with a tapered threaded interior to allow a user to insert the wire into a tapered opening.

Representative examples of twisted wires of conventional wire connectors are described in US Pat. Nos. 3,497,607, 3,875,324, and 4,691,079.

To use the twisted wire of the wire connector, the user inserts the twisted ends of the wire into the cavity inside the twisted wire of the wire connector, then grasp the wire with one hand and twist the wire with the other hand. Was twisted.

The twisting action acts on the connecting end of the wire to reduce the contact electrical resistance.

When the wire connector is in a humid place, a sealant seal is required around the connector.

In order to prevent water or moisture from entering the connector and preventing the formation of an oxide layer on the ends of the wire, the user immersed the wire connector and the wire in a potting compound.

The compound is a non-curable or curable compound in which case the compound forms a waterproof coating around the wire connector and the connecting end of the wire.

The electrical connection is made simultaneously by another wire connector so that unstripped electrical leads are placed in the sealant by pushing the knife-shaped member by the insulation on the electrical conductors and directly into the insulator. Make contact with the wires below.

Such wire connectors are each held together without any spirals and require wire connectors to form a single connection between each wire, and make electrical contact between the knife-shaped member and the electrical conductor. If it is not firmly formed, it is impossible to form a desirable electrical connection.

Accordingly, the present invention allows the user to form a connection end of the stranded wire leads of the wire by one continuous operation so that the contact electrical resistance is reduced and the spiral electric conductor is a waterproof sealant. Provides a retrofit of the wire connector which is covered by encapsulating agents to form a waterproof covering around the connecting end of the spiral conductor.

Conventional wire connectors are manufactured by molding a shell around a spiral coil to form a conventional wire connector.

In the present invention, two molding processes are constructed.

In this process, a conventional wire connector is set in a mold and a second shell is molded around the conventional wire connector, and the user includes a covering material to press the connection ends of the wires together in a single operation so that the contact electrical resistance A twisted wire coated on a wire connector having a chamber including a coating material is produced to reduce the reduction and to cover the connection end of the wire in the sealant.

Accordingly, the present invention fixes a conventional twist on wire connector in a housing forming one chamber and sealant a wire junction encapsulating twist covering the wire connection capsule. by providing an on-wire connector, thereby providing an improvement in the method of manufacturing twisted wire connectors covering wire connections.

As an example, the user inserts the helix end of the wire through an end cap into the sealant in the wire sheath twisted wire connector.

As the user grips the wire, the twisted wire connector is twisted, forming a wire connection between the wires, and at the same time, a coating such as a waterproof or anti-ignition coating is formed on the twisted electrical leads. To manufacture waterproof and fireproof twisted pair connectors.

In another embodiment, the end cap consists of a perforated member so that the user can insert the twisted connection end of the wire into the twisted wire connector through the perforated end cap.

As yet another example, the wire-clad braided wire connector constitutes two chambers to form a solidified coating at the connection of the wires located in the wire-laid braided wire connector.

The invention will be described below in accordance with the drawings.

1 will be described. Reference numeral 10 denotes a waterproof and fireproof twisted pair connector which simultaneously forms an electrical connection with a low contact cell resistance between the connection ends of the electrical conductor, together with a waterproof and anti-ignition coating.

The twist on wire connector 10 includes an electrically insulated, substantially cylindrical housing 11, which housing is rotatably fastened to the end cap. The end cap is composed of a cylindrical tube or sleeve 12 having a cylindrical opening 16 and one end closed.

At the closed end of the housing 11, a conductive collar 40 is located, the collar 40 having a first cylindrical interior surface 13 and a spiral surface ( 14) has a taper wire coil (converging or tapered wire coil) forming.

In the figure, the collar 40 is seen as a one-piece winding coil, but the winding coil is preferably composed of two parts. Since the collar 40 is fixed to the housing 11, an electrical connection with low contact electrical resistance is formed by the user twisting the housing 11 and the collar 40 around the twisted wire conductor end.

The housing 11 has a cylindrical surface 16 for rotatably supporting the sleeve 12 and an annular opening positioned on the cylindrical surface to prevent axial movement of the sleeve 12 in the housing 11. Except for (18), it has almost the same shape as a conventional wire connector.

The wire connector of the present invention is shown in the figure together with a conductive collar 40 having a winding coil forming a spiral surface, but depending on the application, a non-conductive collar having a twilsting surface may be used instead of the winding coil. have.

The cylindrical tube or sleeve 12 is rotatably connected to the opening end of the housing 11.

The cylindrical tube 12 has an outer cylindrical surface 34 with an annular cylindrical rotaining bead 17 formed radially outwardly from the cylindrical butt 12. Have

In the inner cylindrical face 16 of the housing 11 is located a cylindrical recess 18 formed over the power supply circumference of the face 16.

The support (17) is coupled to the annular groove (18) to allow the cylindrical tube (12) in the housing (11) to perform an axial movement. The housing 11 is rotated relative to the tube 2 so that the tube 12 does not axially escape from the housing 11. Although the support protrusion 17 is shown to be annular in the figure, the support protrusion 17 supports the end cap 12 at a position that can be rotated inside the housing 11, so it is necessary to have a sufficient depth.

A portion of the cylindrical surface 34 is engaged with the cylindrical opening 16 without a gap to prevent the sealant from leaking out. That is, by the combination of the annular gap between the two surfaces and the support protrusion 17 and the annular groove 18, the leakage of the sealant in the wire connector of the present invention is effectively prevented when used and when used.

The waterproof and fire resistant wire connector 10 includes interior compartments 21, 22, 23, and 25, part of which is filled with viscous sealant 29. It is.

The sealant 29 may be mainly composed of a silicone base, a potting compound, greases or other waterproof and fire retardant compounds.

Viscous sealants that remain inherently inflexible and remain in the wire connector are preferred because the sealant will not leak when the wire connector is stored or used. However, in other materials, for example, an immersion compound that hardens when contacted with air can be used. In general, representative materials that can be used in the present invention include waterproofing and fire retardant oils, immersion compounds and the like. A typical commercial sealant is the product CONTAX, which is an antioxidant compound.

The sealant is not only effective for preventing oxidation of the wire conductors that degrade the electrical connection characteristics, but also serves to support the wires in the wire connectors. The sealant also covers the exposed portions of the wire conductors and is effective in suppressing the sparks that ignite volatile gases and other combustible materials. At the end of the sleeve 12 a fixture cover is formed which constitutes a plurality of flexible shaped resilient segments 26, so that a pointed end 26a of the section 26 is provided. ) Are in contact with each other (Fig. 5).

Each segment overlaps slightly to support the sealant 29 inside the wire connector 10 when using and transporting the waterproof wire connector.

Before use, keep it in place without securing it in a waterproof and fireproof wire connector box. Since the end of the sleeve is covered by the overlapping section, the sealant is not attached to the other wire connector. When using a waterproof sealant that hardens in contact with air, a continuous member may be used instead of the section 26. When the wire end is inserted into the sleeve using a punching member, the wire end passes through the continuous member.

FIG. 5 shows a state in which the cutting edges 26a are bent inward by inserting the wires 30 and 31 into the waterproof wire connector. Therefore, the wires are inserted by the intercepts, and at the same time, the bends are restored by flexibility, thereby sealing the periphery of the wires.

When inserting the twisted wire into the cylindrical tube (sleeve), the flexible piece 26 is bent inward around the wire to insert the wire into the cylindrical cavity 21, Depending on the size and shape of the wires, matching openings are naturally formed. 3 shows the sealant 29 filling the cavity when an electric wire is inserted into the connector to move the sealant 29.

In order to explain the operation of the present invention will be described with reference to FIG. 2, FIG. 3 and FIG.

2 shows a state in which a twisted junction 33 formed in the wires 30 and 31 is inserted into the cavity 25 filled with the sealant. The electric wire 30 has an electrical insulating coating 30a around the metal wire 30b. Similarly, the electric wire 31 has an electrical insulation coating 31a around the metal wire 31b.

3 shows the connecting end of the electric wire inserted into the cavity 21, and the connecting end 33 of the twisted electric wire is in contact with the inner surface 31 of the collar 40. As shown in FIG.

4 shows a state in which a connection between the conductors of the wire is formed at the same time with a waterproof and fireproof and low contact electrical resistance inside the waterproof wire connector. The operator grasps the wires 30 and 31 and the outer surface 34 of the cylindrical tube (sleeve) 12 with one hand to form the electrical connection and the waterproof and anti-ignition coating simultaneously. The end portions 30 and 31 are axially inserted into the chambers 21 and 22 of the housing 11.

When the connecting end of the electric wire is inserted into the chambers 21 and 22, the operator holds the outer surface 29 of the housing 11 with the other hand.

Then, when the operator rotates the housing 11 while holding the wire and the sleeve, the connecting end 33 of the wire is strongly twisted to contact the metal collar 40.

At the same time, the viscous sealant 29 filled in the cavities 21, 22, 23, and 25 forms a waterproof and anti-ignition protective coating around the connection end 33 of the wire, so that the wire connector is waterproof and fire resistant. Will have

By using the sealant together with the twist of the wire connector, the connection in the housing 11 can be combined and sealed at the same time, and the water and moisture which oxidizes the wire conductor to deteriorate the electrical characteristics of the connection. Is prevented from entering the housing 11.

Although the sealant is present in the cavities 21 and 22, it has been confirmed that the sealant does not prevent the contact terminal resistance of the wire conductor from twisting by rotating the housing 11 to realize a low contact electrical resistance connection.

The embodiment of FIG. 1 shows a sleeve 12 rotatably mounted in a housing 11 of a wire connector. In the embodiment, the sleeve 12 may be connected to be fixed to the housing 11 of the wire connector, depending on the application.

For example, if the sealant can flow, the sealant flows around the wire connector housing as the sleeve rotates around the housing of the wire connector. When the sealant flows, an air hardening material such as epoxy is used to form a waterproof covering at the twisted end of the wire connector.

In order to retain the sealant in the rigid wire connector, a segment having a spiral-like structure that is bent inward and axially around the wire connector can be used when rotating the wire connector housing.

In a further variant of the invention, the end seal has a flexible piece that allows it to rotate relative to the sleeve.

By way of example, the bending segment 26 has an annular base region 28 that is rotatably mounted in an annular recess of the sleeve 12.

6, another embodiment of the present invention is denoted by 50. The connector 50 has the same elasticity that the connector 50 is positioned on a first resilient wire clip 54 on one side of the housing 12 and another side of the housing 12. It is the same as the connector 10 except that the wire clip 53 is included.

The same parts in FIG. 6 and FIG. 1-FIG. 5 show the same code | symbol. The resilient wire clip 54 is formed in all directions with a curved section 55 terminated at the end 62 which is slightly inclined so that the wire can slide between the clip 54 and the surface 34. Compress the member.

Similarly, the clip 53 constitutes a curved surface 56 and an inclined end portion 61.

6 shows that the wire 51 is formed in the direction of the sleeve end at the same time through the end of the sleeve 12 and the opening around the clip 54. The purpose of the clip is to prevent the wire 51 from being pulled from the wire connector 11 when processing the wire.

6 also shows that the wire 52 is formed in the direction of the sleeve end through the end of the sleeve 12 and the opening around the clip 53. Equally, the purpose of the clip 53 is to prevent the wire 52 from being pulled out of the wire connector 11 when processing the wire.

Although only two wires are shown in the drawing, one wire or a plurality of wires may be used. In addition, although two clips are shown, one clip is sufficient to keep two or more wires from being pulled out of the housing 12.

Referring to FIG. 8, reference numeral 70 denotes a twisted wire connector having a cylindrical slant or housing 73 having a first flange 71 and a second flange 72.

The first wire 80 and the second wire 81 are formed outward from the twisted wire connector 70. The purpose of these flanges is to simply construct a gripping surface so that the user can be molded at the twisted wire-connector against a pair of twisted wires, such as wires 80 and 81.

7 shows a cross-sectional view of a twisted wire connector 70 having an end cap consisting of a cylindrical threaded insert 74 having a waterproof sealant in the twisted wire connector 70. end view).

The end cap 74 has an outer support ring with a plurality of flexible pie shaped segments 76 formed by overlapping arrangement towards the center of the end cap 74 ( 75) to form a flexure cover closure on the end cap of the twisted pair connector 70.

FIG. 11 is a perspective view showing an annular support ring 77 including a male thread 77 engaged with a female thread inside an ordinary twisted pair connector.

9 shows an end cap 74 positioned at the end of the twisted pair connector. The twisted wire connector 70 includes a set of conical female threads 91 for fastening with a conical male screw 91a on the outer side of the metal insert 92 and a conical female screw 93 for fastening with an electrical lead on the inner side. do. The twisted ends of the wires 80 and 81 are positioned in contact with the insert 92.

Wires 80 and 81 are formed through flexible segments 76 bent around these wires such that sealant 110 of twisted wire connector 70 flows out of the ends of the twisted wire connector 70. A barrier is formed to prevent it.

Depending on the frictional resistance between the female thread 90 and the male thread 77, the insert 74 may rotate when the user twists at the twisted wire connector with respect to the ends of the wires 80 and 81, It may not rotate. In both cases, the elastic deflection piece retains the sealant at its connector. The end cap 74 can quickly convert a reference twisted wire connector with an inner female thread into a waterproof twisted pair connector by screwing the insert 74 into the female thread 90 located inside the twisted wire connector 70. There is an advantage to this.

Longer wire nuts can also hold more sealant. When the elastic flexible piece 6 is sufficiently bent, the user can grasp the wires 80 and 81 with one hand and rotate them against the wires in the twisted wire connector.

The twisted wire connector 70 and the end cap 74 are rotated with respect to the fixed wire so that the twisted wire connector 70 is twisted while being in electrical contact with the metal insert 92 in the twisted wire connector 70. While retaining the sealant, the elastic flexible segments can bend not only inward but also laterally. Mainly, the bending sections can be made of polymer plastic or the like.

10 illustrates another embodiment, in which the end cap is a non-rotatable insert 102 comprising an elongated cylindrical portion or sleeve 100 protruding outward beyond the end of the twisted wire connector 70. )

The twisted pair connector of FIG. 10 has the advantage of being positioned in the twisted pair connector sleeve 102. The end cap 102 includes a first end 103 having a male thread 104 that engages the female thread 90 in the twisted wire connector 70.

In fact, some of the excess sealant may leak out of the connector during processing. The end of the twisted wire connector 70 includes a shoulder 105 for adjoining and fixing the connector 70 with respect to the annular surface 105a at the end cap 102.

The embodiment of FIG. 9 has the advantage of converting a conventional twisted wire connector into a waterproof connector with a container with a sealant such that the electrically connected twisted ends are covered with the sealant.

Although the end cap 74 is shown as being screwed to the connector 70, the end cap is secured to the connector using adhesive or interlocks to retain the sealant. Compartments can be formed.

Although the end cap 74 exhibits a fitting inside the twisted wire connector 70, the end cap 74 is suitable for forming an external collar to be secured to the periphery of the twisted wire connector. It can be done.

In the embodiments of FIGS. 7 to 11, twisted wire connectors including female threads may be easily used in a sealed container having a protective material such as a viscous waterproof material.

In the illustrated embodiment, the sealant is pre-filled, but the sealant may be injected into the compartment formed by the end cap and the twisted wire connector by selecting a position.

For example, a soluble tube dispenser may be used to inject a sealant into the twisted wire connector before inserting the wire into the twisted wire connector. That is, one process can inject a water-resistant sealant and another process can inject an anti-ignition sealant. As such, the present invention provides field selection of sealants to meet the device setup required by the user.

Various processes do not require an end cap suitably holding the sealant. For example, if the sealant ages and hardens, the sealant itself may form a cap.

In Fig. 12, reference numeral 100 denotes a conventional twisted pair connector in which the method of the present invention is protected in a shell.

The twisted wire connector 100 has an inner spiral metal wire core 112, an upper part 111, an upper compartment 191, a lower compartment 190, and a set of lower gripping ridges ( 112a) and a top edge 100e.

FIG. 17 shows a shell 115 having a cap 125 positioned on an end portion of the shell 115 that forms a hermetic interior region or compartment 139 on the twisted wire connector 100.

A spout connected to the sealant supply source 140 is inserted through the cover 125 to pass the sealant material 142 into the compartment or chamber 190 formed by the lower region of the twisted wire connector 100. send. That is, the sealant material 142 flows into the inner region 190 below the twisted wire connector 100.

In the charging process, the user first inserts the sealant through the spout 141 to the bottom of the inner region 190 of the twisted wire connector 100 and moves upward when the twisted wire connector 100 is charged with the sealant. The twisted wire connector 100 is charged without bubbles.

A typical sealant used in the twisted wire connector is Noalox (manufactured by Ideal Industries, Inc.), an anti-seizing compound consisting of an antioxidant and fine zinc particles suspended on a carrier material. compound).

However, the perforation member 158 can be used as a replacement member of the cover when partially used.

To use the apparatus of FIG. 20, the user inserts the ends of the wires through the puncturing members 158 and 152 into the cavity 190 of the twisted wire connector 100.

By this insertion process, the punching members 158 and 152 are punched out. Once the wire end is present in the connector 150, the user rotates the wire several times to mix the two part materials 151 and 154. When the mixture is a two-part epoxy material, the epoxy material is cured to form a solidified covering at the ends of the wire and the twisted wire connector 100.

Finally, in the manufacturing method of the twisted wire connector which encapsulates the wire connection, the twisted wire binding coil is first set in the mold.

A space is formed in the mold so that the twisted wire binding coil can form a mold cavity around the outer region. An inner region of the twisted wire binding coil having a wire engaging surface that grips and supports the wire ends is covered in the mold to prevent molding material from entering the inner region of the twisted wire connector.

Next, a moldable electrical insulating material such as polyethylene is injected into the mold cavity to form a housing around the twisted wire binding coil.

When removing a solidified housing in the mold, the housing has an opening with one inner region and an inner region of the housing closest to the inner region of the twisted wire connection coil.

In the next step, a capsule coating such as a sealant is injected into the inner region of the twisted wire binding coil and the inner region of the housing.

Once the sealant is set in the inner region of the twisted wire binding coil, the user then inserts the end of the wire into the sealant and bonds with the wire binding surface in the inner region of the twisted wire binding coil.

Once assembled, the user uses the connector to simultaneously form a gripping engagement between the end of the wire and the wire engagement surface and the sealant covering on the end of the wire.

To grip and hold the wire in the connector, the user rotates the housing while holding and holding the wire.

Rotation of the twisted wire binding coil causes the wire binding surface to grip and secure the end of the wire. At the same time, the sealant covers and encapsulates the ends of the wires that are connected to the wire tie surfaces.

In still another embodiment of the present invention, a connector obtained by mixing a pesticide into the plastic can be used to kill insects that can be attracted to a junction box including a wire connection.

Sustained-release insecticides in ear tags are known in the art and in the present invention, and polymers may be used having sustained-release insecticides in at least one portion of the outer shell of the connector.
