Definitions

  • the invention relates to electrical connectors. Particularly, the invention relates to branch connectors.
  • Electrical connectors are used to electrically connect electrical wires with each other.
  • a branch connector can be used to electrically connect one wire with a plurality of wires. This may enable electrical current and/or signal to travel from said one wire to said plurality of wires.
  • DE202016100486 discloses a clamping body for an electric connection device and a connection device comprising a clamping body.
  • the invention is an aluminium clamping body for an electric connection device and a connection device comprising said type of clamping body.
  • Said clamping body has three-dimensional properties acting as current density concentration agent.
  • EP2783422 discloses an electrical connector configured to maintain an electrical connection with a conductor during heating and cooling cycles is provided, and having the features disclosed in the preamble of claim 1.
  • the electrical connector includes connector sections, each comprising a base portion and top portion extending from the base portion.
  • Each connector section defines a portion of a channel configured to receive one or more conductors and includes a bore in its base or top portion that communicates with the channel.
  • a fastener inserted into the bore is configured to retain the conductor inserted into the channel, and the top portions are configured to deflect substantially independently of each other to provide a spring force that secures the fastener against the conductor.
  • DE202016100466 discloses a device with a housing and an aluminum clamping body that can be placed in the housing, wherein the aluminum clamping body has a profile in a bottom area and the housing in a bottom area has a supporting profile that matches the profile of the aluminum clamping body having, the profile of the aluminum clamping body as a means for transferring torques acting on the aluminum clamping body to the supporting profile of the housing and the supporting profile of the housing acts as a means of absorbing the torques.
  • an additional gap extending parallel with the cavities is provided in the body of the branch connector. This increases flexibility of the branch connector which in turn reduces the effect of movement by the wires and/or by the branch connector. As the effect of movement is reduced, the electrical connection between the branch connector and the wires may be more robust. This may be experienced as, for example, decreased maintenance costs.
  • adjacent cavities may be separated from each other.
  • a connector may have two through holes arranged such that a wire can be inputted to the holes from each direction. So, two holes may enable connecting four wires with each other. However, as explained above, this may generate problems in electrical connection between the wires and the connector.
  • Figure 1 illustrates a branch connector 100 according to an embodiment which this problem is addressed.
  • Figure 1 may be understood as illustrating the branch connector 100 from one of its ends (see E1 and E2 e.g. in Figure 2 ).
  • Figure 1 may be a frontal view of the branch connector 100.
  • the branch connector 100 comprises: a plurality of adjacent cavities 112, 114 for receiving the electrical wires (see 510, 520, 530, 540 in Figures 5A, 5B , and 6 ) through open ends (see E1 and E2 e.g.
  • FIG. 2 a plurality of holes 202, 204, 208, 210 (these holes are illustrated in Figures 2 and 4 , for example) extending to the plurality of adjacent cavities 112, 114; and a plurality of pressing elements 512, 522, 532, 542 (these elements are shown in Figures 5B and 5C, for example) for extending through the plurality of holes 202, 204, 206, 208 and for pressing the electrical wires 510, 520, 530, 540 in the plurality of adjacent cavities 112, 114 against a body 110 of the branch connector 100.
  • the body 110 of the branch connector is electrically conducting.
  • the branch connector 100 further comprises a gap 120 extending in a direction that is parallel with a direction of the plurality adjacent cavities 112, 114.
  • Such gap may provide flexibly and/or elasticity to the body 110. In other words, such arrangement may increase flexibility and/or elasticity of the body 110 compared to the prior art solutions.
  • Such parallel extending gap 120 is not discussed in the known solutions.
  • the gap 120 and the plurality adjacent cavities 112, 114 have a common inner surface 192.
  • a wall 122 between adjacent cavities 112, 114 comprises the gap 120 extending in a direction that is parallel with a direction of the adjacent cavities 112, 114, the gap 120 opening a space between the adjacent cavities 112, 114 (i.e. opening the wall 122) and defining the adjacent cavities 112, 114 to have a common inner surface 192.
  • the gap 120 is understood as an aperture between the cavities 112, 114.
  • the gap 120 is understood as a gap that provides flexibility to the body 110, or at least increases flexibility compared with solutions that do not comprise said gap 120.
  • the gap 120 and the adjacent cavities 112, 114 having the same inner surface is a difference to the prior art in which the cavities 112, 114 are closed from each other and do not comprise the gap 120 that increases flexibility of the body 110.
  • Figure 8 represents branch connector according to an example embodiment.
  • the branch connector 100 may be otherwise similar as discussed with respect to Figures 1, 2 , 3, 4 , 5A, 5B , and 6 , but the gap 120 may be situated and/or formed differently. That is, the gap 120 may be situated between the cavities 112, 114 and the upper part or section of the body 110. As shown in the Figure, the cavities 112, 114 may be substantially enclosed by additional walls 802, 804. However, these walls comprise a hole or opening 812, 814 for the pressing elements so that the pressing elements can be used to press the wires against the body (e.g. against portion 132, 134).
  • the holes or openings 812, 814 define the cavities 112, 114 and the gap 120 to have a common inner surface 192.
  • the gap 120 is for providing flexibility for the branch connector 100.
  • the gap 120 may extend to area of both cavities 112, 114 (e.g. if two cavities are used). In a way it can be understood that the gap 120 prevents the upper section of the body 110 to be in contact with the lower section of the body 110 from other areas than the side walls so that the upper section between the side walls may flex.
  • the gap 120 is situated between the side walls (i.e. outer walls) of the body 110 or branch connector 100, and shares a common inner surface with the cavities 112, 114.
  • the difference with Figure 1 is that the additional walls 802,804 are used, and hence the gap 120 has a bit different dimension and location. Effect may remain the same.
  • the gap 120 is situated at an upper portion of the body 110.
  • the gap 120 may define a space between the wall 122 and an upper wall or upper portion of the body 110. This is explicitly shown in Figure 1 , for example.
  • the wall 122 may separate the cavities 112, 114 from each other, and especially the lower portions of the cavities which are configured to receive the wires 510, 520. So, the wall 122 may extend from the lower portion or bottom wall of the body 110 towards the upper portion of the body, but as shown in Figure 1 , may not extend to the upper wall of the body 110. Hence, there may be the gap 120 as shown in Figure 1 , for example.
  • This gap 120 provides flexibility and thus enhance the electrical connection between the body 110 and the wires 510, 520.
  • the common inner surface 192 means that the cavities 112, 114 share the same space and therefore have the same inner surface 192.
  • the wall 122 between the cavities 112, 114 so that the wires (lets refer only to 510 and 520 at this point) may have a reserved or designated slot in the branch connector 100. So, essentially each cavity 112, 114 may be for receiving one wire 510, 520, and the wall 122 between the cavities enables the wires not to be in direct contact with each other.
  • the gap 120 is situated at an upper portion of the wall 122. This can be seen in Figure 1 , for example.
  • Upper portion may refer here to the part that is closer to the plurality of holes 202, 204, 206, 208.
  • the wires 510, 520 may configured to be pressed against portions 132, 134 that may be situated at a lower portion of the branch connector 100.
  • the upper portion may refer to the section that is located between the holes 202, 204, 206, 208 and holes 804, 814.
  • the branch connector 100 in the prior art solutions there is no gap 120 in the wall 122 (see e.g. Figure 1 ) or between the cavities and the upper section (see Figure 8 ).
  • the presently suggested gap 120 enables the branch connector 100 to be more flexible and thus enhances the electrical connection between the wires 510, 520 and the branch connector 100.
  • the flexibility may be caused by the upper part of the branch connector 100.
  • at least the upper part may flex (i.e. move with respect to the wall 122 at least from the area that is opposite to the wall 122) as shown with an arrow 592 in Figure 5B .
  • the gap 120 extends whole length of the adjacent cavities 112, 114.
  • the cavities 112, 114 extend from one open end E1 to another open end E2 of the branch connector 100.
  • the cavities 112, 114 are thus open from both sides (i.e. through holes).
  • the length of the cavities 112, 114 thus refers to the length from end E1 to end E2, and the gap 120 thus extends from end E1 to end E2.
  • the gap 120 extends at least half of the length of the adjacent cavities 112, 114.
  • the gap 120 extends at least three fourths of the length of the adjacent cavities 112, 114.
  • the gap 120 may extend less than the whole length of the cavities 112, 114.
  • the diameter D2 of the gap 120 in the wall 122 is less than a half of a diameter D1 of a cavity of the plurality of adjacent cavities 112, 114.
  • cavities 112, 114 and/or gap 120 are not necessarily uniformly shaped (e.g. cavities 112, 114 may have different shape than a circle which may also be possible).
  • D2 is less than fourth of D1. So, a relatively small gap may suffice.
  • the diameter of the aperture 120 in the wall 122 may be substantially small so that there is a substantially large space for each wire in each cavity.
  • the wires 510, 520 could spread and come into physical connection with each other when the pressing means are used to press the wires against the portion(s) 132, 134.
  • direct physical connection between copper and aluminum wires may increase oxidation and/or corrosion.
  • the wire strands may spread too much (i.e. because of the pressing force) and the electrical connection between the body 110 and the wire may become less conducting.
  • the body 110 comprises aluminum.
  • the body can be made of aluminum or aluminum alloy.
  • the aluminum alloy is high strength aluminum alloy.
  • the body 110 is coated.
  • the coating may comprise tin.
  • the coating may be performed, for example, with tin or tin alloy.
  • the coating may be a tin coating. Coating may reduce oxidation and/or corrosion, for example.
  • Aluminum body 110 and tin coating are used as examples and therefore other materials may be employed. However, aluminum and tin may be especially suitable for the branch connector 100 due to their electrical properties and corrosion resistance. So, the wires 510, 520 may be connected with the electrically conducting body 110.
  • the branch connector 100 further comprises a cover for the body 110.
  • Said cover is shown in Figure 6 with reference sign 610 and may be electrically insulating (e.g. plastic cover).
  • the cover 610 may enclose the body 110.
  • the cover further encloses the pressing elements 512, 522, 532, 542.
  • the cover 610 may enclose the whole branch connector 100.
  • the portion 132, 134 is toothed. So, at least a part of an inner surface of each of the plurality of adjacent cavities 112, 114 may be toothed. This may increase quality of the electrical connection between the wires and the body 110, as the toothed potion 132, 134 may break surface of the wires. So, for example, if a wire has oxidation(s), the toothed portion 132, 134 may remove or reduce such oxidation(s) from the wire when the wire is pressed against the toothed portion 132, 134. For example, the pressing elements 512, 522 may be screwed (i.e. rotated), and the screwing may further enhance the oxidation breaking effect.
  • the wire may be pressed between the element 512, 522 and the portion 132, 134.
  • the plurality of holes 202, 204 and the plurality of pressing elements 512, 522 are arranged and dimensioned such that tightening a pressing element 512, 522 causes an electrical wire 510, 520 to be pressed against the toothed part 132, 134 of the inner wall of the cavity 112, 114.
  • the outer side walls of the body 110 comprise a thinning or thinnings 212, 214.
  • Side walls may be illustrated with S1 and S2 in Figure 2 . So, both side walls of the body 110 may comprise a thinning 212, 214. This thinning may further enhance the flexing of the upper part of the body 110. Skilled person understands what is meant with a thinning: essentially it means that at least a portion of the side wall has a thinner section compared to some other portion of the side wall.
  • the body 110 may essentially have a cuboid or cubic shape (e.g.
  • the side walls of the body 110 may be flexible.
  • the thinned walls may be understood also as walls having reduced thickness compared with the top and/or bottom walls of the body 110 or compared with the side walls without the thinning.
  • D1 is 1 to 3 centimeters (cm), preferably about 2 cm.
  • D2 is 1 to 5 millimeters (mm), preferably about 3 or 4 mm. However, this may depend on the diameters of the body 110. It may suffice that there is a gap regardless of the size of the gap.
  • width of the body 110 may be between 4 and 6 cm (e.g. 5.5 cm), and height between 3 to 5 cm (e.g. 4 cm).
  • Length may be between 5 and 8 cm, for example. So, for example, the cavities 112, 114 and the gap 120 may be about 5 to 8 cm long.
  • the thinning 212 and/or 214 is about 1 mm deep with the above described diameters. In relative terms, the thinning may be between 1 and 2 percent of the total width of the body 110, for example. It is noted that the thinning 212, 214 may be situated either at the outside or inside surface of the side wall, or both.
  • Figures 3 and 4 illustrate some embodiments of the branch connector 100.
  • Figure 3 illustrates a side view (e.g. S1) and
  • Figure 4 illustrates a top view of the branch connector 100.
  • Figures 3 and 4 may illustrate branch connector 100 shown in Figures 1 and 2 or in Figure 8 .
  • the thinning 212 may be situated between the ends E1 and E2. In an embodiment, the thinning 212 extends the whole length of the body 110 as shown in Figure 3 .
  • the holes 202, 204, 206, 208 are shown (these holes can be referred to as apertures or bolt holes also).
  • the toothed part may be seen through the holes 202-208. So, for example, if a wire is inputted into a cavity, a pressing element may be used to tighten the wire against the toothed part via the corresponding hole 202-208. For example, in the example of Figure 4 , four wires can be inputted (two in each cavity from opposite ends E1, E2).
  • Figures 5A and 5B illustrate some example embodiments about wires 510, 520 in the cavities 112, 114 and how they can be tightened or fixed to the cavities 112, 114. It is noted that only two wires 510, 520 are shown as only one end (e.g. E1 or E2) is illustrated. As noted above, two more wires can be inserted into the cavities 112, 114 from opposite sides.
  • the wires 510, 520 are shown within the cavities, but they are not yet fixed to the cavities 112, 114 respectively.
  • pressing elements 512, 522 are shown each associated with a respective hole (i.e. holes 202-208) and wire 510, 520. Pressing element 512 is shown to be tightened more than pressing element 522 in the Figure. As shown, the tightening the pressing element 512, 522 causes the space between the pressing element and portion 132, 134 to reduce, and thus the wire 510, 520 is pressed against the portion 132, 134. Majority of the electrical connection may thus happen via the portion 132, 134.
  • the wires 510, 520 may, due to the pressing force, conduct majority of the electrical current via the lower portion of the body 110.
  • This electrical connection is illustrated with arrow 577 in Figure 5B . This may be caused by the wires 510, 520 having most of their surface area being in direct contact with the lower portion of the body 110 (e.g. portion 132, 134).
  • conducting material is used in the pressing elements 512, 522, electrical connection may happen also via said pressing elements.
  • the pressing force may cause the wire to spread.
  • the designated cavities may be beneficial.
  • wall 122 may prevent the wire 510 to spread too much and enables the wire 510 to remain in shape. This enhances electrical connection.
  • the wall 122 may prevent the wires 510, 520 to become in direct contact with each other. This may be beneficial, for example, if one of the wires 510, 520 comprises and/or is aluminum and the other comprises and/or is copper. Direct contact between aluminum and copper wires may increase oxidation.
  • the pressing elements 512, 522 are bolts or screws. Therefore, the holes 202-208 may comprise a thread for the bolts or screws. So, bolts or screws may be one way to enable tightening the wires 510, 520 against the portion 132, 134.
  • Figure 6 illustrates an embodiment.
  • the plurality of adjacent cavities 112, 114 are through holes, the plurality of adjacent cavities comprising first and second cavities 112, 114, wherein the first cavity 112 is configured to receive a first wire 510 via a first open end E1 of the branch connector 100 and a third wire 530 via a second open end E2 of the branch connector 100, and wherein the second cavity 114 is configured to receive a second wire 520 via the first open end E1 and a fourth wire 540 via the second open end E2.
  • pressing elements 512, 522, 532, 542 e.g. bolts
  • Only hole 202 is illustrated with reference sign, but each pressing element may be inputted into a respective hole in the body 110.
  • an electric circuit comprising the branch connector 100 and the plurality of wires 510, 520, 530, 540.
  • the plurality of wires 510, 520, 530, 540 comprise at least one aluminum wire and at least one copper wire.
  • the branch connector 100 further comprises the cover 610.
  • the cover 610 may enclose the body 110, but comprise openings for the pressing elements 512, 522, 532, 542 and for the wires 510, 520, 530, 540. I.e. wires may be inputted/outputted and the pressing elements operated accordingly via the openings.
  • the cover 610 may comprise a base and a lid, wherein the body 110 may be inputted into the base and enclosed using the lid which may be removably attachable to the base.
  • the cover 610 may further comprise attachment elements for attaching the branch connector 100 to an external object, such as a wall or a ceiling.
  • the cover 610 such as the lid, comprises elements configured to penetrate to the cavities 112, 114, for example, via holes 266, 267 shown in Figure 4 .
  • Said elements may prevent the wires inputted from opposite sides to the same cavity 112, 114 from becoming into direct contact with each other. So, the holes 266, 267 may be located such that they are situated approximately above cavities 112, 114 halfway between opposite ends E1, E2. Said cavities 266, 267 may be similar as holes 202-208, but may have a smaller diameter.
  • Figure 7 illustrates a flow diagram illustrating a manufacturing method according to the invention.
  • the method for manufacturing a plurality of branch connectors comprises: obtaining a longitudinally extending blank bar comprising open ends, a plurality of adjacent cavities and a gap (block 710) (e.g. the gap is situated between the adjacent cavities as discussed in some embodiments); cutting the longitudinally extending blank bar transversely into sub-sections, each sub-section defining a body of the branch connector (block 720); and providing the plurality of pressing elements into the corresponding plurality of holes (block 730).
  • the blank bar is cut (e.g. using water cutting) into sub-sections where each sub-section forms a body 110 of the branch connector 100. So, the cavities 112, 114 are already present in the blank bar. Similarly, the gap 120 is also present in the blank bar.
  • the cutting is thus used to form the bodies 110 from a blank bar that may have essentially the same features as the body 110 (but is longer).
  • the holes 202, 204, 206, 208 are machined in the blank bar.
  • the pressing elements for fixing the wires are provided to each sub-section (i.e. each body 110) once the holes 202-208 are present in the blanks.

  • Figures 9 , 10 , 11 , 12 , 13 , and 14 illustrate some embodiments of the branch connector 100 and/or the body 110.
  • Figures 9 to 12 illustrate some example embodiments regarding the position and/or dimensions of the gap 120 and/or the wall 122.
  • Figures 13 and 14 relate to the detachable attachment of some parts of the branch connector 100 and specifically the body 110.
  • the gap 120 may be arranged at any location on the wall 122.
  • the gap 120 may be situated in any location on the wall 122.
  • Figure 1 it is illustrated to be situated in the upper part of the wall 122, but in Figure 9 it is shown to be situated in the lower part of the wall 122 (e.g. at the level of the portions 132, 134 and between the portions 132, 134).
  • the gap 120 may be situated in the middle of the wall 122.
  • Upper wall may refer to the portion of the wall 122 that is closer to the holes 202, 204 and lower wall may refer to the portion of the wall 122 that is closer to the toothed portions 132, 134.
  • the wall 122 may comprise on or more portions 122A, 122B.
  • the wall 122 may comprise two portions 122A, 122B.
  • one of the portions 122A extends from the upper portion of the body 110 towards lower portion of the body 110, and the other portion 122B extends from lower portion of the body 110 towards upper portion of the body 110.
  • the portions 122A, 122B are arranged to lap with each other or in other words be parallel with each other (see Figure 10 ).
  • the portions 122A, 122B are arranged within each other (see Figure 12 ). So, in the example of Figure 12 the portion 122A is situated partially within portion 122B.
  • the gap 120 may be arranged between the portions 122A, 122B. Therefore, there is room for the portions 122A, 122B to move and thus provide flexibility for the body 110 and thus improve the electrical connection between the body 110 and the wires 510, 520.
  • the gap 120 may extend parallel with the cavities 112, 114, and further extends the whole length of the cavities 112, 114 (i.e. from one open end E1 to other open end E2).
  • the body 110 comprise at least one detachable part 1302, 1304.
  • upper part 1302 of the body 110 may be removably attachable.
  • lower part 1304 of the body 110 may be removably attachable.
  • both parts 1302, 1304 may be removably attachable.
  • the upper part 1302 is shown to be detachably attachable to the body 110 (e.g. to the rest of the body 110 comprising the lower part 1304).
  • the different parts (e.g. 1302, 1304) of the body 110 may be attachable directly or via adapter(s) to each other.
  • the body 110 is an integral body 110. Therefore, it may be formed by one integral part (e.g. integral aluminum part).
  • the wall 122 is removably attachable to the body 110 (e.g. directly or via adapter). So, for example, the body 110 may not initially comprise the wall 122 which can be fixed to the body 110 later.
