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.
- 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 may be understood as an aperture between the cavities 112, 114.
- the gap 120 may be 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 804, 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 804, 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, 812 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 may provide flexibility and thus enhance the electrical connection between the body 110 and the wires 510, 520.
- the common inner surface 192 may mean that the cavities 112, 114 share the same space and therefore have the same inner surface 192.
- 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 may extend from one open side E1 to another open side E2 of the branch connector 100.
- the cavities 112, 114 may thus be open from both sides (i.e. through holes).
- the length of the cavities 112, 114 may thus refer to the length from end E1 to end E2, and the gap 120 may thus extend 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 thinnigs 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 an embodiment.
- the method for 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 may be 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 may be 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 may be already be present in the blank bar. Similarly, the gap 120 may also be present in the blank bar.
- the cutting may thus be used to form the bodies 110 from a blank bar that may have essentially the same features as the body 110 (but is longer). However, the holes 202, 204, 206, 208 may either be present in the blank bar or be added later in the process.
- the pressing elements for fixing the wires may be provided to each sub-section (i.e. each body 110) once the holes 202-208 are present in the blanks.
- the pressing elements may be, for example, pre-tightened or pre-fixed to the body 110.
- wires such as wires 510, 520.
- wires mean electric(al) wires or electric(al) cables, such as electric wires for conducting electricity and/or electric signals.
- the branch connector 100 can be used to provide signal from one wire to plurality of wires (i.e. branching).
- the described connector it is possible to use the described connector as an in-line connector, for example. So, for example, two wires can be electrically connected with each other using the branch connector 100.
- the wires 510, 520, 530, 540 are aluminum wires.
- the wires 510, 520, 530, 540 are copper wires.
- the wires 510, 520, 530, 540 comprise both at least one aluminum wire and at least one copper wire.
- the wires 510, 520, 530, 540 comprise at least two wires. In an embodiment, the wires 510, 520, 530, 540 comprise four wires.

Abstract
Description
- 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. For example, 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.
- Normally such branch connectors suffer from problems with quality of connection. For example, movement of the connector and/or the wires may cause the electrical connection between the connector and the wires to deteriorate. Therefore, there seems to be room to develop connectors that reduce the effect of such movement on the quality of the electrical connection (s).
- According to an aspect, there is provided the subject matter of the independent claims. Some embodiments are defined in the dependent claims.
- In the presently disclosed branch connector, 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.
- One or more examples of implementations are set forth in more detail in the accompanying drawings and the description below. Other features will be apparent from the description and drawings, and from the claims.
- In the following embodiments will be described in greater detail with reference to the attached drawings, in which
-
Figures 1, 2 ,3, and 4 illustrate branch connectors according to some embodiments; -
Figures 5A and 5B illustrate attachment of wires into the branch connector according to some embodiments; -
Figure 6 illustrates an electrical circuit comprising a branch connector and plurality of wires; -
Figure 7 illustrates a manufacturing method according to an embodiment; and -
Figures 8, 9 ,10, 11 ,12, 13 ,14 illustrate the branch connector according to some embodiments. - The following embodiments are exemplifying. Although the specification may refer to "an", "one", or "some" embodiment(s) in several locations of the text, this does not necessarily mean that each reference is made to the same embodiment(s), or that a particular feature only applies to a single embodiment. Single features of different embodiments may also be combined to provide other embodiments.
- In prior art solutions, adjacent cavities (there can be more but at least two cavities) may be separated from each other. For example, 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 abranch connector 100 according to an embodiment which this problem is addressed.Figure 1 may be understood as illustrating thebranch connector 100 from one of its ends (see E1 and E2 e.g. inFigure 2 ). E.g.Figure 1 may be a frontal view of thebranch connector 100. Referring toFigure 1 , thebranch connector 100 for connecting a plurality of wires with each other is shown. Thebranch connector 100 comprises: a plurality ofadjacent cavities Figures 5A, 5B , and6 ) through open ends (see E1 and E2 e.g. inFigure 2 ) of thebranch connector 100; a plurality ofholes Figures 2 and4 , for example) extending to the plurality ofadjacent cavities pressing elements Figures 5B and 5C , for example) for extending through the plurality ofholes electrical wires adjacent cavities body 110 of thebranch connector 100. Thebody 110 of the branch connector is electrically conducting. - Moreover, in the presented
branch connector 100, thebranch connector 100 further comprises agap 120 extending in a direction that is parallel with a direction of the pluralityadjacent cavities body 110. In other words, such arrangement may increase flexibility and/or elasticity of thebody 110 compared to the prior art solutions. Such parallel extendinggap 120 is not discussed in the known solutions. - In an embodiment, the
gap 120 and the pluralityadjacent cavities inner surface 192. One example of this is shown e.g. inFigure 1 , wherein awall 122 betweenadjacent cavities gap 120 extending in a direction that is parallel with a direction of theadjacent cavities gap 120 opening a space between theadjacent cavities 112, 114 (i.e. opening the wall 122) and defining theadjacent cavities inner surface 192. In a way, thegap 120 may be understood as an aperture between thecavities gap 120 may be understood as a gap that provides flexibility to thebody 110, or at least increases flexibility compared with solutions that do not comprise saidgap 120. Moreover, thegap 120 and theadjacent cavities cavities gap 120 that increases flexibility of thebody 110. - However, it is possible to obtain the
gap 120 in different ways. One such example is shown inFigure 8 which represents branch connector according to an example embodiment. Referring toFigure 8 , thebranch connector 100 may be otherwise similar as discussed with respect toFigures 1, 2 ,3, 4 ,5A, 5B , and6 , but thegap 120 may be situated and/or formed differently. That is, thegap 120 may be situated between thecavities body 110. As shown in the Figure, thecavities additional walls portion 132, 134). The holes oropenings cavities gap 120 to have a commoninner surface 192. In all embodiments, thegap 120 is for providing flexibility for thebranch connector 100. In the embodiment ofFigure 8 , thegap 120 may extend to area of bothcavities 112, 114 (e.g. if two cavities are used). In a way it can be understood that thegap 120 prevents the upper section of thebody 110 to be in contact with the lower section of thebody 110 from other areas than the side walls so that the upper section between the side walls may flex. - Some other embodiments are discussed later with respect to the embodiments of
Figures 9 ,10 ,11 ,12 ,13 , and14 . - So, in an embodiment, the
gap 120 is situated between the side walls (i.e. outer walls) of thebody 110 orbranch connector 100, and shares a common inner surface with thecavities Figure 8 , the difference withFigure 1 is that theadditional walls 802, 812 are used, and hence thegap 120 has a bit different dimension and location. Effect may remain the same. - In an embodiment, the
gap 120 is situated at an upper portion of thebody 110. For example, thegap 120 may define a space between thewall 122 and an upper wall or upper portion of thebody 110. This is explicitly shown inFigure 1 , for example. Thewall 122 may separate thecavities wires wall 122 may extend from the lower portion or bottom wall of thebody 110 towards the upper portion of the body, but as shown inFigure 1 , may not extend to the upper wall of thebody 110. Hence, there may be thegap 120 as shown inFigure 1 , for example. Thisgap 120 may provide flexibility and thus enhance the electrical connection between thebody 110 and thewires - Going back to the other embodiment shown e.g. in
Figure 1 , skilled person understands that the commoninner surface 192 may mean that thecavities inner surface 192. However, it is noted that there is thewall 122 between thecavities branch connector 100. So, essentially eachcavity wire wall 122 between the cavities enables the wires not to be in direct contact with each other. Accordingly, in an embodiment, thegap 120 is situated at an upper portion of thewall 122. This can be seen inFigure 1 , for example. Upper portion may refer here to the part that is closer to the plurality ofholes wires portions branch connector 100. In the embodiment ofFigure 8 , the upper portion may refer to the section that is located between theholes holes - As the skilled person understands, 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 (seeFigure 8 ). The presently suggestedgap 120 enables thebranch connector 100 to be more flexible and thus enhances the electrical connection between thewires branch connector 100. The flexibility may be caused by the upper part of thebranch connector 100. As there is thegap 120, at least the upper part may flex (i.e. move with respect to thewall 122 at least from the area that is opposite to the wall 122) as shown with anarrow 592 inFigure 5B . - In an embodiment, the
gap 120 extends whole length of theadjacent cavities Figure 2 showing a dimensional view of thebranch connector 100, thecavities branch connector 100. Essentially, thecavities cavities gap 120 may thus extend from end E1 to end E2. - In an embodiment, the
gap 120 extends at least half of the length of theadjacent cavities - In an embodiment, the
gap 120 extends at least three fourths of the length of theadjacent cavities Figure 11 thegap 120 may extend less than the whole length of thecavities 112, 114.Referring toFigure 1 , the diameter D2 of thegap 120 in thewall 122 is less than a half of a diameter D1 of a cavity of the plurality ofadjacent cavities cavities gap 120 are not necessarily uniformly shaped (e.g. cavities Figure 1 , D2 is less than fourth of D1. So, a relatively small gap may suffice. So, the diameter of theaperture 120 in thewall 122 may be substantially small so that there is a substantially large space for each wire in each cavity. For example, if there would be nowall 122 between thecavities wires wall 122 the wire strands may spread too much (i.e. because of the pressing force) and the electrical connection between thebody 110 and the wire may become less conducting. Hence, it may be beneficial to have the proposedopen cavity cavity - In an embodiment, the
body 110 comprises aluminum. For example, the body can be made of aluminum or aluminum alloy. In an embodiment, the aluminum alloy is high strength aluminum alloy. - In an embodiment, the
body 110 is coated. For example, the coating may comprise tin. Hence, the coating may be performed, for example, with tin or tin alloy. E.g. 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 thebranch connector 100 due to their electrical properties and corrosion resistance. So, thewires body 110. - In an embodiment, the
branch connector 100 further comprises a cover for thebody 110. Said cover is shown inFigure 6 withreference sign 610 and may be electrically insulating (e.g. plastic cover). Thecover 610 may enclose thebody 110. In an embodiment, the cover further encloses thepressing elements cover 610 may enclose thewhole branch connector 100. - Referring now to
Figures 1, 2 , and8 , theportion adjacent cavities body 110, as thetoothed potion toothed portion toothed portion pressing elements element portion holes pressing elements pressing element electrical wire toothed part cavity - According to an embodiment, with reference to
Figure 1 and 2 , the outer side walls of thebody 110 comprise a thinning orthinnigs Figure 2 . So, both side walls of thebody 110 may comprise a thinning 212, 214. This thinning may further enhance the flexing of the upper part of thebody 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. For example, in the present example Figures, thebody 110 may essentially have a cuboid or cubic shape (e.g. is a rectangular cuboid), where side walls are thinner compared with, for example, upper and lower sections of thebody 110. I.e. the outer side walls may be thinner than top and bottom walls of thebody 110 which can be observed for example inFigures 1 and8 . Essentially, the side walls of thebody 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 thebody 110 or compared with the side walls without the thinning. - In an embodiment, D1 is 1 to 3 centimeters (cm), preferably about 2 cm.
- In an embodiment, 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. - For example, 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, thecavities gap 120 may be about 5 to 8 cm long. - In an embodiment, 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. - However, it needs to be noted that these dimensions should be understood as examples of some embodiments, and it is possible to utilize different dimensions depending on the wires or cables that need to be connected with each other.

Figures 3 and 4 illustrate some embodiments of thebranch connector 100.Figure 3 illustrates a side view (e.g. S1) andFigure 4 illustrates a top view of thebranch connector 100. For example,Figures 3 and 4 may illustratebranch connector 100 shown inFigures 1 and 2 or inFigure 8 . - As shown in
Figure 3 , the thinning 212 may be situated between the ends E1 and E2. In an embodiment, the thinning 212 extends the whole length of thebody 110 as shown inFigure 3 . - In
Figure 4 , theholes Figure 4 , four wires can be inputted (two in each cavity from opposite ends E1, E2). -
Figures 5A and 5B illustrate some example embodiments aboutwires cavities cavities wires cavities - Referring to
Figure 5A , thewires cavities Figure 5B ,pressing elements wire Pressing element 512 is shown to be tightened more than pressingelement 522 in the Figure. As shown, the tightening thepressing element portion wire portion portion wires body 110. This electrical connection is illustrated witharrow 577 inFigure 5B . This may be caused by thewires e.g. portion 132, 134). Naturally, if conducting material is used in thepressing elements - Still referring to
Figure 5B , the pressing force may cause the wire to spread. Hence, as noted above, the designated cavities (although opened) may be beneficial. As shown in the Figure,wall 122 may prevent thewire 510 to spread too much and enables thewire 510 to remain in shape. This enhances electrical connection. Also, thewall 122 may prevent thewires wires - In an embodiment, the
pressing elements 512, 522 (and also 532, 534) 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 thewires portion -
Figure 6 illustrates an embodiment. Referring toFigure 6 , the plurality ofadjacent cavities second cavities first cavity 112 is configured to receive afirst wire 510 via a first open end E1 of thebranch connector 100 and athird wire 530 via a second open end E2 of thebranch connector 100, and wherein thesecond cavity 114 is configured to receive asecond wire 520 via the first open end E1 and afourth wire 540 via the second open end E2. As shown in the Figure,pressing elements wires body 110. Onlyhole 202 is illustrated with reference sign, but each pressing element may be inputted into a respective hole in thebody 110. - According to an embodiment, there is provided an electric circuit comprising the
branch connector 100 and the plurality ofwires wires - In an embodiment, with reference to
Figure 6 , thebranch connector 100 further comprises thecover 610. Thecover 610 may enclose thebody 110, but comprise openings for thepressing elements wires cover 610 may comprise a base and a lid, wherein thebody 110 may be inputted into the base and enclosed using the lid which may be removably attachable to the base. Thecover 610 may further comprise attachment elements for attaching thebranch connector 100 to an external object, such as a wall or a ceiling. - In an embodiment, the
cover 610, such as the lid, comprises elements configured to penetrate to thecavities holes Figure 4 . Said elements may prevent the wires inputted from opposite sides to thesame cavity holes cavities cavities -
Figure 7 illustrates a flow diagram illustrating a manufacturing method according to an embodiment. Referring toFigure 7 , the method for for manufacturing a plurality of branch connectors (i.e. branch connector 100) comprises: obtaining a longitudinally extending blank bar comprising open ends, a plurality of adjacent cavities and a gap (block 710) (e.g. the gap may be 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). - More precisely, the blank bar may be cut (e.g. using water cutting) into sub-sections where each sub-section forms a
body 110 of thebranch connector 100. So, thecavities gap 120 may also be present in the blank bar. The cutting may thus be used to form thebodies 110 from a blank bar that may have essentially the same features as the body 110 (but is longer). However, theholes body 110. - Above, reference is made, for example, to wires such as
wires branch connector 100 can be used to provide signal from one wire to plurality of wires (i.e. branching). However, it is possible to use the described connector as an in-line connector, for example. So, for example, two wires can be electrically connected with each other using thebranch connector 100. - In an embodiment, the

Figures 9 ,10 ,11 ,12 ,13 , and14 illustrate some embodiments of thebranch connector 100 and/or thebody 110. Specifically,Figures 9 to 12 illustrate some example embodiments regarding the position and/or dimensions of thegap 120 and/or thewall 122.Figures 13 and14 relate to the detachable attachment of some parts of thebranch connector 100 and specifically thebody 110. - Referring to
Figure 9 , thegap 120 may be arranged at any location on thewall 122. For example, inFigure 1 it is illustrated to be situated in the upper part of thewall 122, but inFigure 9 it is shown to be situated in the lower part of the wall 122 (e.g. at the level of theportions portions 132, 134). However, in an embodiment, thegap 120 may be situated in the middle of thewall 122. Upper wall may refer to the portion of thewall 122 that is closer to theholes wall 122 that is closer to thetoothed portions - Referring to
Figures 10 and12 , thewall 122 may comprise on ormore portions 122A, 122B. For example, thewall 122 may comprise twoportions 122A, 122B. In one example, one of theportions 122A extends from the upper portion of thebody 110 towards lower portion of thebody 110, and the other portion 122B extends from lower portion of thebody 110 towards upper portion of thebody 110. In an embodiment, theportions 122A, 122B are arranged to lap with each other or in other words be parallel with each other (seeFigure 10 ). In an embodiment, theportions 122A, 122B are arranged within each other (seeFigure 12 ). So, in the example ofFigure 12 theportion 122A is situated partially within portion 122B. In the described embodiments ofFigures 10 and12 , thegap 120 may be arranged between theportions 122A, 122B. Therefore, there is room for theportions 122A, 122B to move and thus provide flexibility for thebody 110 and thus improve the electrical connection between thebody 110 and thewires - It is noted that in the described solution, the
gap 120 may extend parallel with thecavities cavities 112, 114 (i.e. from one open end E1 to other open end E2). However, this is not always necessary as shown inFigure 11 , wherein thegap 120 is situated at either end E1, E2 of thebody 110 and extends parallel with thecavities body 110. So, there may be a neck in thewall 122 that connects the lower and upper parts of thebody 110 to each other. The neck is thinner than the length of thebody 110. In another example, thegap 120 may be situated at both ends of the E1, E2 of the body and the neck may be situated therebetween. In such case thegap 120 comprise actually two gaps separated by the neck. So, the neck may be situated at either end E1, E2 of the body or between the open ends E1, E2. Essentially, thegap 120 does not necessarily extend the whole length of thebody 110. However, in some embodiments it does, and it may be beneficial for providing a considerably simpler manufacturing process. - Referring to
Figure 13 , thebody 110 comprise at least onedetachable part upper part 1302 of thebody 110 may be removably attachable. For example,lower part 1304 of thebody 110 may be removably attachable. For example, bothparts body 110. In the example ofFigure 13 , theupper part 1302 is shown to be detachably attachable to the body 110 (e.g. to the rest of thebody 110 comprising the lower part 1304). The different parts (e.g. 1302, 1304) of thebody 110 may be attachable directly or via adapter(s) to each other. - However, in an embodiment, the
body 110 is anintegral body 110. Therefore, it may be formed by one integral part (e.g. integral aluminum part). - In the example of
Figure 14 , thewall 122 is removably attachable to the body 110 (e.g. directly or via adapter). So, for example, thebody 110 may not initially comprise thewall 122 which can be fixed to thebody 110 later. - Even though the invention has been described above with reference to an example according to the accompanying drawings, it is clear that the invention is not restricted thereto but can be modified in several ways within the scope of the appended claims. Therefore, all words and expressions should be interpreted broadly and they are intended to illustrate, not to restrict, the embodiment. It will be obvious to a person skilled in the art that, as technology advances, the inventive concept can be implemented in various ways. Further, it is clear to a person skilled in the art that the described embodiments may, but are not required to, be combined with other embodiments in various ways.
