Description

MULTI-PORT CABLE TERMINAL

Technical Field

[0001] The present invention relates to a multi-port cable terminal, and more particularly, to a multi-port cable terminal, whereby connection of a cable can be easily performed.

Background Art

[0002] Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

[0003] Generally, cables for using a high-frequency signal or an optical signal are connected to equipment and components, such as switching station equipment, base station equipment and a repeater or relay device for wired or wireless communication.

[0004] Because communication companies use different frequencies, high-frequency signals or optical signals having various frequencies need to be connected to equipment such as an antenna, and even when the communication companies use the same frequencies, the antenna needs to distribute at least three or more cables so as to transmit or receive signals in a direction of 360 degrees.

[0005] In this way, a multi-port cable terminal is used to distribute the cables. As examples of multi-port cable terminals, as disclosed in U.S. Patent No. US 7,653,282 (entitled "Multi-port Optical Connection Terminal") and U.S. Patent No. US 7,740,409 (entitled "Multi-port Optical Connection Terminal"), one stub cable is connected to a terminal and is branched into a plurality of parts within the terminal and is connected to each port.

[0006] The port is installed to be inclined with respect to the stub cable by about 45 degrees. That is, the stub cable is installed to be perpendicular to the ground, and the port is inclined with respect to the ground by 45 degrees. Thus, moisture can be minimized from flowing into the stub cable through the port.

[0007] A connector to which the cable is connected, is coupled to the port, and an opposite side of the cable is connected to other equipment such as an antenna, via the connector. A key and a key way are formed so as to precisely couple the port and the connector to each other.

[0008] However, while the connector to which the cable is connected, is installed, a direction of a key or key way disposed in the connector may not coincide with a direction of a key way or key disposed in the port due to a twisted cable.

[0009] In this case, in order to couple the connector to the port by fitting the key and the key way, when the cable is twisted or rotated, a glass fiber inside the cable may be shorted.

[0010] In addition, a much working time is required to couple the port to the connector, and a work for coupling the port to the connector is performed at a relatively higher position from the ground such that a delay in the working time may cause an increase in the risk of a worker's safety accident.

[0011] As a different problem from the above-mentioned problem, it is not easy to change an initial installation position of a multi-port cable terminal according to the related art, and due to interference with peripheral equipment, connection of the cable may not be easily performed.

[0044] Hereinafter, exemplary embodiments of the present invention will be described with reference to accompanying drawings schematically illustrating the embodiments. In the drawings, for example, illustrated shapes may be deformed according to fabrication technology and/or tolerances. Therefore, the exemplary embodiments of the present invention are not limited to certain shapes illustrated in the present specification, and may include modifications of shapes caused in fabrication processes.

[0045] FIG. 1 is a perspective view of a multi-port cable terminal according to an exemplary embodiment of the present invention.

[0046] Referring to FIG. 1, the multi-port cable terminal according to the exemplary embodiment of the present invention includes installation surfaces 210, 220, and 230, which are inclined horizontally or at an acute angle with respect to the ground, a terminal body 200 for distribution, a fixing installation part 300 for fixedly installing the terminal body 200 at a wall surface or pillar, and ports 100, at least one of which is installed at the installation surfaces 210, 220, and 230 of the terminal body 200 and which can be rotated in an installation state.

[0047] Each of the ports 100 includes a fixed part 110, a bearing 120, fixing rings 130 and 140, a rotation part 150, and a connection part 160.

[0048] The fixed part 110 is fixed within the terminal body 200, and the bearing 120 is rotatably coupled to the fixed part 110. The rotation part 150 coupled to the bearing 120 is rotated together with rotation of the bearing 120. The connection part 160 is fixedly installed at an inside of the rotation part 150 and is rotated by rotation of the rotation part 150 so that the position of a connection pin 161 inserted into a connection hole can be adjusted.

[0049] A key display part 151 is formed at the rotation part 150 so that the position of a key or key way can be easily checked from the outside.

[0050] Thus, when coupling a connector (not shown) to which a cable is connected, to the ports 100, a worker may rotate the rotation part 150 so as to make the position of a key display part disposed in the connector and the position of the key display part 151 of the rotation part 150 coincide with each other, thereby easily coupling the key display part of the connector to the key display part 151 of the rotation part 150.

[0051] The connection part 160 includes connection pins 161 into which a protruding conduction part of the connector is inserted, and which can be electrically or optically connected to one another via the conduction part.

[0052] In this way, according to the present invention, in a state in which distortion or twisting of the cable occurs while the cable is installed so that the key or key way of the connector and the key way or key of the port 100 do not coincide with each other, the position of the key way or key of the port 100 can be changed so that easy coupling of the connector to the port 100 can be performed.

[0053] FIG. 2 is a perspective view of a coupling state of the port 100 according to the present invention, and FIG. 3 is a view of a cross-sectional configuration of the coupling state of the port 100.

[0054] Hereinafter, a detailed configuration and operation of the port 100 will be described with reference to FIGS. 2, 3 and 1 in more detail.

[0055] First, the fixed part 110 has a cylindrical shape and a seating surface 113 is formed in a middle side of an inner diameter of the fixed part 110 so that an inner diameter of a top side of the fixed part 110 is greater than an inner diameter of a bottom side of the fixed part 110. The fixed part 110 is solidly fixed at an inside of the terminal body 200. In this case, very various methods of fixing the fixed part 110 may be used, and as one thereof, a tap may be formed at an outer diameter of the fixed part 110, and a ring-shaped socket part into which the fixed part 110 is inserted and fixed, may be disposed in the terminal body 200.

[0056] Abearing 120 isdisposed at the seating surface 113ofthefixed part110.The bearing 120 is only in contact with the seating surface 113 and is not coupled thereto but may be rotated. The bearing 120 has a ring shape.

[0057] A bearing-coupling part 155 to which the bearing 120 is coupled, is disposed in the rotation part 150. The bearing-coupling part 155 that is a tap disposed on one surface of the rotation part 150, is engaged with a tap disposed on an inner diameter surface of the bearing 120. Thus, the rotation part 150 may be rotated together with the bearing 120.

[0058] The rotation part 150 has an overall cylindrical shape, and an angled (hexagonal or rectangular) tool contact part 153 protrudes from an outside of a middle part of the rotation part 150. The tool contact part 153 is used to couple the rotation part 150 to the bearing 120 using a wrench, etc. The tool contact part 153 is used to fix the rotation part 150 not to rotate, using a tool when the connector is couple to the cable. Also, the tool contact part 153 is in contact with a bottom end of the fixed part 110 so that an airtight retention force can be improved.

[0059] At least one airtight part 156 is disposed between the bearing-coupling part 155 and the tool contact part 153 of the rotation part 150. The airtight part 156 that is a ring made of an elastic material, prevents moisture from flowing through a space between the rotation part 150 and the fixed part 110.

[0060] Fixing rings 130 and 140 prevent deviation of the airtight part 156.

[0061] A stopper 152 protrudes from the rotation part 150, and the stopper 152 is inserted into a cutting part 112 of the fixed part 110. The cutting part 112 is disposed on a part of the bottom end of the fixed part 110. Both side surfaces of the cutting part 112 act as a rotation prevention protrusion 111.

[0062] That is, when the rotation part 150 is rotated and a side surface of the stopper 152 is in contact with the rotation-prevention protrusion 111, the rotation part 150 cannot rotate in the same direction any more.

[0063] A rotational angle of the rotation part 150 can be set using the cutting part 112 and the rotation-prevention protrusion 111, and rotation of the rotation part 150 can be limited within the range of 180 to 350 degrees.

[0064] Also, a structure in which the cutting part 112 and the stopper 152 are omitted, is possible, and in this case, rotation of the rotation part 150 is not limited.

[0065] A connector-coupling part 154 is formed at an outer diameter of a bottom end of the rotation part 150 so that the connector can be coupled to the port 100. The connector coupling part 154 may be a tap.

[0066] The above-described key display part 151 is disposed between the connector coupling part 154 and the tool contact part 153. Also, at least one key way 157 is formed at an inside of the bottom end of the rotation part 150 having the connector-coupling part 154 formed therein.

[0067] Although the key way 157 is formed in the rotation part 150 and the key is formed in the connector being coupled to the connector-coupling part 154, on the contrary, a key may be formed in the rotation part 150, and a key way may be formed in the connector.

[0068] The connection part 160 is coupled to the inside of the rotation part 150. The connection part 160 that is an insulator, includes at least one connection pin 161. The connection pin 161 may be a conductor for transmitting high-frequency signals or a means for transmitting optical signals.

[0069] In an example of a configuration of the port 100, when the key of the connector connected to the cable and the key way 157 of the port 100 are not in the same direction, the rotation part 150 can be rotated so that the direction of the key and the direction of the key way 157 can be fitted to each other and thus the key and the key way 157 can be easily coupled to each other.

[0070] In FIG. 1, the fixing installation part 300 is a configuration for solidly fixing the terminal body 200 to the wall surface or pillar. In particular, an insertion groove 310 is formed to solidly install the terminal body 200 at the pillar. The fixing installation part 300 is bound and fixed by a strap, etc. in a state in which a part of the pillar is inserted into the insertion groove 310.

[0071] Also, an end of the insertion groove 310 is formed as an unevenness surface 311 so that the fixing installation part 300 can be prevented from descending along the pillar due to gravity.

[0072] FIG. 4 is a view of a configuration according to another exemplary embodiment of the present invention.

[0073] Referring to FIG. 4, a terminal body 200 does not include a plurality of installation surfaces and has a plurality of ports 100 formed on a bottom surface thereof, unlike in the above description. In this case, the plurality of ports 100 may be rotated and thus may be easily connected to the connector. A detailed configuration of the port 100 has been described with reference to FIGS. 1 through 3 and thus will be omitted.

[0074] The terminal body 200 may have a cylindrical shape with a semispherical top portion thereof and may be coupled to a fixing installation part 300 using a strap 320.

[0075] The feature of this structure is that, in a state in which the strap 320 is loosened and the terminal body 200 is rotated, the strap 320 can be tightened again and solidly fix the terminal body 200.

[0076] Thus, the position of the plurality of ports 100 exposed to the bottom surface of the terminal body 200 can be adjusted, and positions of the ports 100 can be adjusted according to a connector connected to each of the ports 100 and a direction in which each of cables connected to the connector extends.

[0077] Thus, the cables can extend without any interference with peripheral equipment. Also, such a structure makes it easy to coincide the key way of each of the ports 100 and the key of the connector described above.

[0078] FIG. 5 is a perspective view of a coupling state of a multi-port cable terminal according to another exemplary embodiment of the present invention, and FIG. 6 is an exploded perspective view of FIG. 5.

[0079] Referring to FIGS. 5 and 6, the multi-port cable terminal according to the current embodiment of the present invention further includes a rotation device unit 400 in addition to the configuration of the above-described embodiment so that the terminal body 200 can be rotated within the range of a predetermined angle in a state in which the fixing installation part 300 is fixed.

[0080] The rotation device unit 400 includes at least a fixed bracket 410 and a rotation bracket 420, and the fixed bracket 410 is fixed to the fixing installation part 300 or the terminal body 200, and the rotation bracket 420 rotatably coupled to the fixed bracket 410 is coupled to the terminal body 200 or the fixing installation part 300.

[0081] In such a configuration, the terminal body 200 may be rotated and moved in a state in which the fixing installation part 300 is fixed to the wall or pillar.

[0082] In the drawings, the fixed bracket 410 is fixed to the fixing installation part 300, and the rotation bracket 420 is fixed to the terminal body 200. However, the fixed bracket 410 may be fixed to the terminal body 200, and the rotation bracket 420 may be fixed to the fixing installation part 300.

[0083] The fixed bracket 410 includes a contact plate 416 that is in contact with the fixing installation part 300 and fixed thereto, a top protrusion plate 417 and a bottom protrusion plate 418, which protrude from top and bottom ends of the contact plate 416, and a first through hole 411 and a second through hole 412, which penetrate the top protrusion plate 417 and the bottom protrusion plate 418, respectively, in a vertical direction.

[0084] Also, the rotation bracket 420 includes a contact plate 423 that is in contact with the terminal body 200 and is fixed thereto, a top protrusion plate 424 and a bottom protrusion plate 425, which protrude from top and bottom ends of the contact plate 423, respectively, and a third through hole 421 and a guide through hole 422, which are formed in the top protrusion plate 424 and the bottom protrusion plate 425, respectively, in the vertical direction.

[0085] In this configuration, the top protrusion plate 417 and the bottom protrusion plate 418 of the fixed bracket 410 are in contact with the top protrusion plate 424 and the bottom protrusion plate 425 of the rotation bracket 420, respectively, in a stacked form.

[0086] In this case, the first through hole 411 communicates with the guide through hole 422, and the second through hole 412 communicates with the third through hole 421.

[0087] A first shaft part 413 is coupled to the first through hole 411 and the guide through hole 422, and a second shaft part 414 is coupled to the second through hole 412 and the third through hole 421, and a fixing unit 415 is coupled to both ends of the first shaft part 413 and the second shaft part 414 and is fixed thereto.

[0088] In this state, a rotation center of the rotation bracket 420 is the second shaft part 414, and the rotation bracket 420 having the circular arc-shaped guide through hole 422 may be guided and rotated while the first shaft part 413 is inserted into the guide through hole 422.

[0089] The configuration of the rotation device unit 400 is one embodiment, and various modifications of a structure thereof is possible.

[0090] FIG. 7 is a perspective view of a rotation device unit 400 according to another exemplary embodiment of the present invention, and FIG. 8 is a partial detailed exploded view of FIG. 7.

[0091] Referring to FIGS. 7 and 8, the rotation device unit 400 may support top and bottom surfaces of the terminal body 200 to be rotatable.

[0092] The rotation device unit 400 that rotatably supports the top and bottom surfaces of the terminal body 200, according to another exemplary embodiment of the present invention includes a contact plate 431 having one surface fixed to the fixing installation part 300, a top protrusion plate 432 that protrudes from a top surface of the contact plate 431 and is disposed at an upper portion of the terminal body 200, a bottom protrusion plate 433 that protrudes from a bottom surface of the contact plate and is disposed at a lower portion of the terminal body 200, a bearing shaft part 434 that couples the top protrusion plate 432 and the terminal body 200 to each other to be rotatable, a bearing nut 435 that fixes the bearing shaft part 434, a coupling hole 437, which is formed in the center of the rotation device unit 400 and through which the connector can be coupled to the port 100, a bearing accommodation part 436 fixedly installed at the bottom protrusion plate 433, a coupling hole 439 that is formed in the center of the rotation device unit 400 and communicates with the coupling hole 437, and a bearing 438 that is accommodated in the bearing accommodation part 436 and is contact with the bottom surface of the terminal body 200.

[0093] Such a configuration is a configuration in which the top and bottom surfaces of the terminal body 200 are fixed to be rotatable using one bracket including the contact plate 431, the top protrusion plate 432 and the bottom protrusion plate 433, and in particular, stable support is possible using the bearing 438 that contacts the bottom surface of the terminal body 200.

[0094] In this way, according to the present invention, when a connector connected to the cable is connected to the port 100 using the rotatable port 100, even when the key of the port 100 and the key way of the connector do not coincide with each other, the port 100 may be rotated so that the key and the key way can coincide with each other, and the terminal body 200 may be rotatably configured so that the position of the port 100 can be adjusted. Thus, according to the present invention, there is no interference with peripheral equipment, and the connector may be easily coupled to the port 100 without being forcedly rotated so that a connection work can be easily performed.

[0095] FIG. 9 is a perspective view of the port 100 according to another exemplary embodiment of the present invention, and FIG. 10 is a view of a cross-sectional configuration of a coupling state of FIG. 9.

[0096] Referring to FIGS. 9 and 10, the port 100 according to another exemplary embodiment of the present invention includes a fixed part 110, a bearing 120, fixing rings 130 and 140, a rotation block 170, a connection part 160, and a port block 180.

[0097] First, the fixed part 110 has a cylindrical shape and a seating surface 113 is formed in a middle side of an inner diameter of the fixed part 110 so that an inner diameter of a top side of the fixed part 110 is greater than an inner diameter of a bottom side of the fixed part 110. The fixed part 110 is solidly fixed at an inside of the terminal body 200.

[0098] The bearing 120 is disposed at the seating surface 113 of the fixed part 110. The bearing 120 is only in contact with the seating surface 113 and is not coupled thereto but may be rotated.

[0099] The rotation block 170 of which a part of a top end is inserted and fixed into the bearing 120 and which rotates together with the bearing 120, is configured to include a block part 173 having a cylindrical top side and a bottom end protruding to a side surface of the block part 173 so as to provide a coupling surface having a predetermined area at a bottom surface. A bearing-coupling part 172 to which the bearing 120 is coupled, is disposed on a top end of the rotation block 170. The bearing-coupling part 172 that is a tap disposed on the top end of the rotation block 170, is engaged with a tap disposed on an inner diameter surface of the bearing 120. Thus, the rotation block 170 may be rotated together with the bearing 120.

[00100] At least one airtight part 171 is disposed between the bearing-coupling part 172 and the block part 173 of the rotation block 170. The airtight part 171 is a ring made of an elastic material and is disposed in a through hole formed in the terminal body 200 in a state of being coupled. That is, the airtight part 171 prevents moisture from flowing in the cable through a space between the rotation block 170 and the terminal body 200 and supports rotation of the rotation block 170.

[00101] The fixing rings 130 and 140 prevent deviation of the rotation block 170.

[00102] A port block 180 is coupled to the block part 173 of the rotation block 170. The port block 180 may be coupled to the rotation block 170 using a fastening means such as a bolt and may be rotated together with the rotation block 170. In this case, a key display part 183 may be disposed at a part of an outer surface of the port block 180 so that the position of a key way 182 can be easily recognized from the outside. A connector-coupling part 181 is formed at an outer diameter of a bottom end of the port block 180. The connector-coupling part 181 may be a tap.

[00103] In this structure, when a connector to which the cable is connected, is connected and the positions of the key of the connector and the key way 182 do not coincide with each other, the port block 180 may be rotated so that the position of the key way 182 can be changed and can be easily coupled to the connector.

[00104] The connection part 160 that is an insulator includes at least one connection pin 161. The connection pin 161 may be a conductor for transmitting high-frequency signals or a means for transmitting optical signals.

[00105] The configuration of the port 100 described with reference to FIGS. 9 and 10 may be applied to the terminal body 200 described with reference to FIGS. 1 through 8.

[00106] While the invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
