Description

Cable Coupler {CABLE COMBINING DEVICE}

The present invention relates to a cable coupler having holes in which a particular member is inserted into another member and a cable can be inserted into the side of the members.

The cable coupler is a device for coupling cables having different electrical characteristics, and has a structure shown in FIG. 1 below.

1 is a top view illustrating a conventional cable coupler, and FIGS. 2 and 3 are perspective views illustrating a structure in which cables are coupled.

Referring to FIG. 1, a conventional cable coupler 100 has a recess in which a Teflon PCB 104 can be placed in the center thereof, and side recesses 102a, 102b, and 102c into which the cables can be inserted. And 102d). In addition, the corners of the cable coupler 100 are formed with holes 106 through which screws are inserted.

Cables 200 are inserted into this cable coupler 100 as shown in FIG. 2, and then the inner conductors 200c of the cables 200 are joined by soldering. Here, the cable 200 consists of an inner conductor 200c, an outer conductor 200b and a sheath 200a.

When attempting to couple the cables 200 to such a cable coupler 100, soldering is applied to the specific portions 202a, 202b and 202c after the cables 200 are laid on the side recesses 102b, 102c and 102d. The recess was performed in the central part. Specifically, a soldering solution is administered to a particular portion 202a in the upper direction after one cable is inserted into the first side recess 102b. In this case, since the cable is in close contact with the first side recess 102b, the brazing solution may not flow to the entire inner surface of the first side recess 102b. Thus, the cable coupler 100 is flipped as shown in FIG. 3 and then soldered again in the downward direction. Then connect the other cables to the corresponding parts in the same way. Subsequently, soldering is performed on the central portion where the inner conductors 200c are collected.

As described above, in the conventional cable coupler 100, not only the cables have to be soldered one by one, but also there are inconveniences in the process of performing soldering in both up and down directions.

In addition, when soldering in the downward direction, it was necessary to feel considerable inconvenience in soldering when there was another object in the downward direction.

In addition, the cable coupler 100 could be made of metal, which could negatively affect conductor-sensitive devices such as antenna elements.

Moreover, when the Teflon PCB 104 is inserted in the center of the cable coupler 100, the Teflon PCB 104 may be shaken by external impact so that the characteristics of the mutually coupled cables may be changed. As a result, for example, the characteristics of the antenna element for performing a specific operation using the cables could not be maintained stably and may be changed.

In addition, since there is no other member surrounding the cable coupler 100, there was a problem that the soldering solution may flow to the outside during soldering.

It is an object of the present invention to provide a cable coupler which can, for example, continue to stably maintain the characteristics of the antenna element while reducing costs and simplifying the process.

In order to achieve the above object, the cable coupler according to an embodiment of the present invention comprises: a first member having first holes; And a second member having a recessed portion in which the first member is inserted in one side and second holes corresponding to the first holes in the other sides.

The first member includes a basic member inserted into the second member; And an extension member extending outwardly from the base member, wherein the cable coupler further comprises a third member arranged over the extension member. Here, at least one hole is formed in the third member so that the third member is fixed by at least one protrusion formed on the extension member, and holes corresponding to the second holes are formed in the third member.

The outer line of the extension member and the outer line of the third member coincide with the outer line of the second member when the basic member is inserted into the second member.

An antenna element according to an embodiment of the present invention comprises at least one radiation element; A plurality of cables used as a transmission path for a specific signal so that a predetermined radiation pattern is output from the radiation element; And a cable coupler for coupling the cables.

4 is a perspective view schematically illustrating components of a cable coupler according to an embodiment of the present invention, and FIGS. 5 to 7 are perspective views illustrating a coupling process of the cable coupler.

Referring to FIG. 4, the cable coupler of the present embodiment is an element used to connect a plurality of cables, and includes a connection member 400, a first intermediate member 402, a second intermediate member 404, and an outer member 406. ).

According to an embodiment of the present invention, the cable coupler may be used to connect cables in an array antenna that outputs a predetermined radiation pattern using at least one radiation element and a phase shifter.

In general, the cables, for example coaxial cables, do not all have the same electrical properties. That is, some of the cables may have different electrical characteristics, for example resistance characteristics, from other cables. In this case, the characteristics of the signals transmitted through the cables are different, and the cables are combined using the cable coupler to compensate for signals having these different characteristics to suit the purpose of use.

Hereinafter, assume that the cable coupled to the cable coupler is the coaxial cable 500 shown in FIG. Coaxial cable 500 generally has an inner conductor 500d, an insulator layer 500c surrounding the inner conductor 500d, an outer conductor 500b surrounding the insulator layer 500c and a coating layer 500a, for example halogen-free. It consists of a jacket (Halogen Free Jacket, HFJ).

The connecting member 400 is made of metal, for example, as a conductor, and has a concave-convex shape as shown in FIG. 4 so that the inner conductors 500d of the cables 500 can be inserted. Of course, the connection member 400 may have various shapes as long as the inner conductors 500d of the cables 500 may be inserted as described below.

The first intermediate member 402 is made of an insulator and has a recess 410 into which the connecting member 400 can be inserted. In addition, first holes 412 through which the cable 500 may be inserted are formed at a side surface of the first intermediate member 402. Here, since the cables 500 generally have a circular shape, the first holes 412 have a circular shape in accordance with the shape of the cables 500. Of course, when another type of cable is used, the first holes 412 will have a shape other than a circular shape.

The first hole 412 has a slightly larger circumference than the insulator layer 500c so that the insulator layer 500c of the cable 500 shown in FIG. 5 can be inserted in close contact. As a result, when the cable 500 is inserted into the first hole 412 of the first intermediate member 402, it is stably fixed even before soldering.

In FIG. 4, the first holes 412 have the same shape, but at least one of the first holes 412 may have a different shape from other first holes. For example, one of the first holes 412 may have a circular shape, and the other first hole may have a rectangular shape.

The second intermediate member 404 is a conductor and has a recess 414 into which the first intermediate member 402 can be inserted. In addition, second holes 416 may be formed in the side surface of the second intermediate member 404 through which the cables 500 may be inserted. Here, the second holes 416 are formed at positions corresponding to the first holes 412, and since the cables 500 have a circular shape, the second holes 416 preferably have a circular shape as shown in FIG. 4.

According to one embodiment of the invention, the second hole 416 has a larger circumference than the first hole 412 and a larger circumference than the outer conductor 500b of the cable 500. As a result, even if the cable 500 is inserted into the second hole 416, the cable 500 does not come into close contact with the second hole 416.

The second hole 416 has a larger circumference than the outer conductor 500b of the cable 500 so that the solder solution flows evenly through the entire inner surface of the second hole 416 during soldering. In detail, the cable 500 includes a third hole 420 of the outer member 406, a second hole 416 of the second intermediate member 404, and a first hole 412 of the first intermediate member 402. In the case of insertion of the cable 500, the inner conductor 500d of the cable 500 is inserted in close contact with the first hole 412 so that the cable 500 is inserted into and fixed to the holes 412, 416, and 420 in a stable state. In this state, the soldering solution is administered from the open portion of the second hole 416 to the inner surface of the second hole 416 to solder the second hole 416. Here, since there is sufficient space for the soldering solution to flow between the second hole 416 and the outer conductor 500b of the cable 500, the soldering solution is evenly distributed over the entire inner surface of the second hole 416. Spreads. Therefore, the outer conductor 500b of the cable 500 may be stably fixed to the second hole 416 while being inserted into the second hole 416.

According to another embodiment of the present invention, the second hole 416 may have a shape different from that of the cable 500. This is because the second hole 416 differs from the cable 500 because the outer conductor 500b does not adhere closely to the second hole 416 and there is a predetermined space between the outer conductor 500b and the second hole 416. Even if it has a shape, there is no problem in fixing the cable 500 to the second hole 416 using the soldering solution.

According to one embodiment of the present invention, the second intermediate member 404 may be a member plated with tin on aluminum (Al) or zinc.

The outer member 406 serves as an insulator to prevent the solder solution from flowing out during soldering and has a recess 418 into which the second intermediate member 404 can be inserted. In addition, third holes 420 corresponding to the holes 412 and 416 are formed in the side surface of the outer member 406.

According to one embodiment of the present invention, the third hole 420 has a circumference slightly larger than the circumference of the outer conductor 500b so that the outer conductor 500b of the cable 500 can be inserted in close contact.

In short, the cable coupler of the present invention has a structure in which a specific member is inserted into another member, and also a structure in which the cables 500 can be stably fixed to the members 400, 402, 404 and 406 even before soldering. Have

Hereinafter, a process of coupling the cable 500 using the cable coupler having such a structure will be described in detail.

First, as shown in FIG. 4, the connecting member 400 is inserted into the first intermediate member 402, and then the first intermediate member 402 is inserted into the second intermediate member 404. Subsequently, the second intermediate member 404 is inserted into the outer member 406. That is, the connecting member 400 and the intermediate members 402 and 404 are inserted into the outer member 406 as shown in FIG.

Subsequently, with the connecting member 400, the intermediate members 402 and 404 inserted into the outer member 406, the cables 500 into the holes 420, 416 and 412 as shown in FIG. 6. Is inserted.

The brazing solution is then administered to the portions 600 shown in FIG. 6. Specifically, the brazing solution is administered to the recess 410 of the first intermediate member 402 to connect the inner conductors 500d and attaches the outer conductor 500b and the second intermediate member 404. The brazing solution is administered to the open portion of the second holes 416 for this purpose. As a result, as shown in FIG. 7, the cables 500 are inserted into and fixed to the connecting member 400, the intermediate members 402 and 404, and the outer member 406.

Hereinafter, the cable coupler of the present invention and the conventional cable coupler will be compared.

First, the cable coupler of the present invention can stably fix the cable 500 without using a Teflon PCB, unlike a conventional cable coupler. Thus, the manufacturing cost of the cable coupler can be reduced. In addition, in the conventional cable coupler, the Teflon PCB may be shaken by an external impact so that the beam characteristics of, for example, the array antenna using the cable coupler may be changed. However, in the cable coupler of the present invention, even when an external impact is applied in the state in which the members 400, 402, 404, and 406 are coupled, the coupling state is not changed, so that the beam characteristics of the array antenna can be continuously maintained.

Second, in the cable combiner of the present invention, the cables 500 to the members 400, 402, 404 and 406 are secured to the members 400, 402, 404 and 406 even before soldering. Soldering could be performed once after inserting. However, in the conventional cable coupler, since the cables are not fixed to the side recesses, the cables have to be placed one by one to the corresponding side recesses and then soldered. Therefore, fixing the cables 500 in the cable coupler of the present invention is easier than fixing the cables in the conventional cable coupler.

Third, the conventional cable coupler had to be soldered up and down when fixing the cable to the corresponding side recesses, but the cable coupler of the present invention performs only one soldering in the upper direction of the members 400, 402, 404 and 406. do. As a result, the process of joining the cables 500 in the cable coupler of the present invention is less process steps and easier to assemble than the process of joining the cables in a conventional cable coupler. In addition, when there is another object in the lower part when joining the cable in the conventional cable coupler, it was not easy to solder the lower part. There is no meaning.

Fourth, in the conventional cable coupler, the cable coupler, which is a metal, may be exposed to the outside to change characteristics of an antenna element and the like which are sensitive to such a conductive object. However, in the cable coupler of the present invention, since the outer member 406 as the insulator surrounds the second intermediate member 404 as the conductor, the second intermediate member 404 is not exposed to the outside. As a result, it does not negatively affect other elements, such as an antenna element.

As described above, the cable coupler of the present invention compensates for all the disadvantages of the conventional cable coupler.

In the above, the members 402, 404 and 406 of this cable coupler all have a rectangular shape, but may have other shapes, for example a circular shape. That is, the shapes of the members 402, 404 and 406 can be variously modified as long as the members 402, 404 and 406 can secure the cables 500 in the manner described above.

According to another embodiment of the present invention, the cable coupler may stably fix the cables 500 only by the intermediate members 402 and 404, and thus may not include the connecting member 400 and the outer member 406. have.

8 is a perspective view showing an outer member according to another embodiment of the present invention.

As shown in FIG. 8, the outer member 800 may have a structure in which one side is open. Since the purpose of the outer member 800 is to prevent the solder solution from flowing out during the soldering, the outer member 800 may have a structure that can surround the holes 416 to be soldered. Of course, even in this case, the outer member 800 should have holes 802 corresponding to the holes 416.

9 is a perspective view showing an outer member according to another embodiment of the present invention.

As shown in FIG. 9, two or more holes may be formed in one side of the outer member so that two or more cables may be inserted. Of course, two or more holes may be formed on one side of the intermediate member corresponding to the holes. Unlike the cable coupler illustrated in FIG. 4, in the cable coupler having such a structure, a plurality of holes may be formed on only one side without forming holes on various sides.

In short, in the cable coupler of the present invention, at least one hole is formed in one side of the specific member.

According to one embodiment of the invention, one of the holes formed in one side may have a different shape or size than the other hole.

10 is a perspective view illustrating a coupling process of a cable coupler according to another embodiment of the present invention, and FIG. 11 is a perspective view illustrating a cable coupler coupled according to the coupling process of FIG. 10.

Referring to FIG. 10, the cable coupler of this embodiment includes a connecting member 1000, a first intermediate member 1002, a second intermediate member 1004, a third intermediate member 1006, and an outer member 1008. .

Since the remaining components except for the first intermediate member 1002 and the third intermediate member 1006 are the same as those of the cable coupler of FIG. 4, the description of the same components will be omitted.

The first intermediate member 1002 is composed of a base member 1010 and an extension member 1014 as shown in FIG.

A recess 1012 is formed at the center of the base member 1010 so that the connection member 1000 can be inserted.

The extension member 1014 is formed to extend in the outward direction from the base member 1010 as shown in Figure 10, the portion that can be inserted, that is, the portion corresponding to the holes of the second intermediate member 1004 Holes 1218 are formed in the hole. According to an embodiment of the present invention, the extending member 1014 has the same shape as the second intermediate member 1004, for example, a quadrangular shape, and the protrusion is formed on the top of the extending member 1014 as shown in FIG. 10. Fields 1016 are formed. Here, the extending member 1014 has a width such that the outer line of the extending member 1014 can coincide with the outer line of the second intermediate member 1004. As a result, when the basic member 1010 of the first intermediate member 1002 is inserted into the recess of the second intermediate member 1004, the extension member 1014 is placed on the second intermediate member 1004 and the extension member ( The outer line of 1014 coincides with the outer line of the second intermediate member 1004.

After the basic member 1010 of the first intermediate member 1002 of this structure is inserted into the second intermediate member 1004, a third intermediate member 1006, for example, a conductor, is placed over the elongate member 1014. However, when the third intermediate member 1006 is placed on the extension member 1014, as shown in FIG. 10, the holes 1020 are formed in the third intermediate member 1006 to form protrusions formed on the extension member 1014. 1016 is inserted into the holes 1020 formed in the third intermediate member 1006. Thus, the third intermediate member 1006 is fixed above the first intermediate member 1002. According to an embodiment of the present invention, when the third intermediate member 1006 rests on the first intermediate member 1002, the outer line of the third intermediate member 1006 coincides with the outer line of the extension member 1014. 3 The width of the intermediate member 1006 is set.

Further, holes 1222 are formed in a portion in which the cables can be inserted, that is, corresponding to the holes of the second intermediate member 1004, in the third intermediate member 1006.

As described above, the first intermediate member 1002 is inserted into the second intermediate member 1004, and then the third intermediate member 1006 is placed over the first intermediate member 1002. Subsequently, the second intermediate member 1004 is inserted into the outer member 1008, and then the cables are inserted into the corresponding holes to form a cable coupler as shown in FIG.

In short, the cable coupler of this embodiment further includes a third intermediate member 1006 than the cable coupler of FIG. As a result, the components of the antenna element except for the cable coupler are isolated from the connecting member 1000 and the inner conductors coupled in the connecting member 1000 by the third intermediate member 1006, thus the configuration of the antenna The elements are not affected by the connecting member 1000 and the inner conductors so that the antenna element can be driven more stably.

12 is a perspective view showing a cable coupling process according to another embodiment of the present invention.

Referring to FIG. 12, the cable coupler of the present embodiment includes a connecting member 1200, a first intermediate member 1202, a second intermediate member 1204, a third intermediate member 1206, and an outer member 1208. .

Since the remaining components except for the first intermediate member 1202 and the third intermediate member 1206 are the same as those of the cable coupler of FIG. 10, the description of the same components will be omitted.

12, protrusions 1210 are formed on the first intermediate member 1202, and holes 1212 are formed at edges of the third intermediate member 1206. As a result, when the third intermediate member 1206 is placed over the first intermediate member 1202, the third intermediate member 1206 can be fixed by the protrusions 1210.
