[Technical field]

[0001] The present invention relates to a transmission line connection device that connects a plurality of transmission lines. [Background technology]

[0002] As the above-mentioned transmission line connection device, an optical connector array case with mounting members is known, which includes an optical connector array case in which multiple optical connectors are arranged on the bottom end surface of the case body, a case holder that detachably holds the optical connector array case, and a fixing plate that is fixed by screws or the like to a wall surface (mounting surface) of a cabinet or a building or the like (see, for example, Patent Document 1).

[0003] The fixing portion has a vertically elongated plate-like portion and a shaft portion that is integrally formed with an upper portion of the front surface (front face) of the plate-like portion and that is formed so as to extend along the lateral direction.

[0004] A first bearing portion is formed on the edge of the back side of the top plate of the case holder, which rotatably and removably engages with the shaft portion of the fixed plate, and a second bearing portion is formed on the edge of one of the side sides of the case holder, which rotatably and removably engages with the shaft portion of the fixed plate.

[0005] According to the optical connector array case equipped with the mounting member, the orientation of the optical connector array case can be determined by attaching either the first bearing portion or the second bearing portion of the case holder to the shaft portion of the fixing plate.

[0006] Furthermore, when the optical connector array case equipped with the mounting parts is installed at the installation location, the orientation of the optical connector array case can be changed to an orientation suitable for work by rotating the optical connector array case together with the case holder around the first bearing portion and the second bearing portion that is attached to the shaft portion of the fixed plate.

[0007] [Patent Document 1] Patent No. 5339633 Summary of the Invention [Problem to be solved by the invention]

[0008] However, after the above-mentioned conventional optical connector array case equipped with mounting parts is installed at the installation location, the orientation of the array case can only be rotated circumferentially around the first axis portion or around the second axis portion, so there is a limit to the range in which the orientation of the array case can be changed, and there is also a limit to the improvements in workability.

[0009] In view of the above circumstances, an object of the present invention is to provide a transmission line connecting device that can further improve workability. [Means for solving the problem]

[0010] The transmission line connection device of the present invention comprises: A bracket that can be fixed to the installation location, a connection device body having a plurality of terminals for connecting transmission lines; a connecting structure that connects the bracket and the connection device body, The bracket and the connection device body are arranged such that their connecting portions are opposed to each other, The connecting structure is a base portion attached to the bracket in a rotatable state about a first axis extending along either a first direction in which the connecting portion of the bracket and the connecting portion of the connection device main body face each other, or a second direction intersecting the first direction; The connection device body has a holding portion that is integrated with the base portion and holds the connection device body in a rotatable state about a second axis that extends along the other of the first direction and the second direction.

[0011] According to the transmission line connection device having the above-described configuration, the connection device body is made rotatable in the circumferential direction about the first axis and in the circumferential direction about the second axis by the connection structure that connects the connection device body and the bracket. Therefore, with the bracket fixed to the installation location, the orientation of the connection device body can be changed by rotating the connection device body in the circumferential direction about the first axis and in the circumferential direction about the second axis.

[0012] Therefore, the transmission line connecting device can easily be oriented in a direction suitable for work, thereby improving workability.

[0013] In the transmission line connection device of the present invention, the coupling portion of the connection device body is located on one side of the connection device body in a third direction intersecting the first direction and the second direction, The plurality of terminal portions may be configured to face the other side in the third direction.

[0014] This allows the terminal portion to be easily oriented toward the worker, improving the convenience of working on the terminal portion.

[0015] In the transmission line connection device of the present invention, The bracket is A connection base portion on which the connection portion is provided; A connecting base portion connected to the connecting base portion, The connecting base portion and the connecting base portion may be configured to be selectively fixed to the installation location.

[0016] In this way, the part to which the bracket is fixed at the installation location can be selected from the connecting base part and the linked base part, thereby increasing the range of options for how the bracket is fixed, and improving convenience during installation work.

[0017] The transmission line connection device of the present invention comprises: The connection device body has a flat box-shaped case, In the case, With a wide surface area, a narrow surface portion having an outer surface area smaller than that of the wide surface portion, The broad surface portion is disposed opposite the connecting base portion, The narrow surface portion may be disposed opposite the connecting base portion.

[0018] According to the transmission line connection device, the space occupied by the connection device when the installation location is viewed from the front changes depending on whether the connecting base part is fixed to the installation location or the connecting base part is fixed to the installation location. Therefore, it is possible to select whether to fix the connecting base part to the installation location or the connecting base part to the installation location depending on the size of the installation location when viewed from the front, thereby improving convenience during installation work.

[0019] In the transmission line connection device of the present invention, The base is configured to be able to maintain a posture by friction with the bracket, The holding portion may be configured to be able to maintain the attitude of the connection device body by friction with the connection device body even in a state in which the transmission line is connected to the terminal portion.

[0020] In this way, even if an operator rotates the connection device body with the transmission line connected to the terminal portion and then releases the connection device body, the posture of the connection device body is maintained, thereby improving the convenience of working on the connection device body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, a transmission line connecting device (hereinafter referred to as a connecting device) according to one embodiment of the present invention will be described with reference to the accompanying drawings.

[0024] The connection device is configured such that an input transmission line and an output transmission line are removably connected from the outside, and a signal passing through the connected input transmission line can be transmitted to the output transmission line.

[0025] The connection device of this embodiment will be described below by taking as an example a device configured to connect an optical communication cable as a transmission line.

[0026] As shown in FIG. 1, the connection device 1 of this embodiment includes a bracket 2 that can be fixed to an installation location, a connection device main body 3 having a plurality of terminal portions for connecting transmission lines, and a connecting structure 4 that connects the bracket 2 and the connection device main body 3.

[0027] 2, the bracket 2 has a connection base part 20 to which the connection device main body 3 is connected, a connection base part 21 connected to the connection base part 20, and a bracket side attachment part 22 formed on the connection base part 20 and serving as an attachment part of the connection structure 4 (part of the connection part that connects the connection device main body 3 by the connection structure 4). The bracket 2 is capable of selectively fixing the connection base part 20 and the connection base part 21 to the installation location.

[0028] The connecting base portion 20 has a plate-shaped connecting plate portion 200, a connecting fixing portion 201 for fixing the connecting plate portion 200 to an installation location, and an anti-slip portion 202 (see FIG. 3(b)) made of rubber.

[0029] The connecting plate portion 200 has an inward surface 2000 facing the connection device main body 3, and an outward surface 2001 facing the opposite side to the inward surface 2000, as shown in FIG. 3(b).

[0030] The outward surface 2001 is a surface that is disposed facing the installation location. In addition, since the outward surface 2001 is a flat surface, when the connecting plate portion 200 is installed on a flat installation location, the outward surface 2001 faces the flat installation location in a state parallel to the flat installation location.

[0031] The connecting and fixing part 201 has a screw fastening part 2010 for fastening the connecting plate part 200 to an installation location with screws, and an attachment part 2011 which can be attached to the installation location.

[0032] The screw fastening portion 2010 is formed from a part of the connecting plate portion 200, and has a through hole formed therein that passes through in the thickness direction of the connecting plate portion 200 (the direction in which the inward surface 2000 and the outward surface 2001 are aligned) (see FIG. 2).

[0033] The affixing portion 2011 is made of a magnetic material (specifically, a magnet). Therefore, when the installation location has magnetic properties, the affixing portion 2011 can be affixed to the installation location. Two affixing portions 2011 are attached to the outward surface 2001 of the connecting plate portion 200.

[0034] The anti-slip portion 202 is attached to the connecting plate portion 200, and is exposed outward from the outward surface 2001. In addition, since the anti-slip portion 202 slightly protrudes outward from the outward surface 2001, when the connecting base portion 20 is installed at an installation location, the anti-slip portion 202 abuts against the installation location, thereby restricting the movement of the connecting plate portion 200 relative to the installation location (i.e., preventing it from slipping).

[0035] Since the anti-slip portion 202 is made of rubber and has elasticity, when the connecting plate portion 200 is pressed against the installation location, the outward surface 2001 as well as the anti-slip portion 202 can be brought into contact with the installation location.

[0036] As shown in FIG. 2, the connecting base portion 21 has a plate-shaped connecting plate portion 210 and a connecting fixing portion 211 for fixing the connecting plate portion 210 to an installation location.

[0037] The connecting plate portion 210 has an inward surface 2100 facing the connection device main body 3, and an outward surface 2101 facing the opposite side to the inward surface 2100, as shown in FIG. 5(b).

[0038] The continuous plate portion 210 and the connecting plate portion 200 are perpendicular or substantially perpendicular to each other (see FIG. 2).

[0039] The outward surface 2101 is the surface that faces the installation location.

[0040] The connecting and fixing part 211 has a screw fastening part 2110 for fastening the connecting plate part 210 to the installation location with screws, and an attachment part 2111 that can be attached to the installation location.

[0041] The screw fastening portion 2110 is formed from a part of the connecting plate portion 210, and has a through hole formed therein that penetrates in the thickness direction of the connecting plate portion 210 (the direction in which the inward surface 2100 and the outward surface 2101 are aligned) (see FIG. 2).

[0042] The affixing portion 2111 is made of a magnetic material (specifically, a magnet). Therefore, when the installation location has magnetic properties, the affixing portion 2111 can be affixed to the installation location. Two affixing portions 2111 are attached to the outward surface 2101 of the connecting plate portion 210.

[0043] The anti-slip portion 212 is attached to the connecting plate portion 210, and is exposed outward from the outward surface 2101. In addition, since the anti-slip portion 212 slightly protrudes outward from the outward surface 2101, when the connecting base portion 21 is installed at an installation location, the anti-slip portion 212 abuts against the installation location, thereby restricting the movement of the connecting plate portion 210 relative to the installation location (i.e., preventing it from slipping).

[0044] Since the non-slip portion 212 is made of rubber and has elasticity, when the connecting plate portion 210 is pressed against the installation location, the outward surface 2101 as well as the non-slip portion 212 can be brought into contact with the installation location.

[0045] As shown in FIG. 2, the connection device main body 3 has a flat box-shaped case 30, a terminal portion 31 that is attached inside the case 30 and configured to allow a transmission line to be detachably connected, a case side attachment portion 32 that is formed on the case 30 and serves as an attachment portion of the connection structure 4 (part of the connection portion that connects the bracket 2 by the connection structure 4), and an inner protrusion portion 33 (see FIG. 10) that protrudes from the inner wall of the case 30.

[0046] The case 30 has a number of wide surface portions 300 (see Figures 3(a) and 3(b)) and narrow surface portions 301 (see Figures 4(a) and 4(b) and Figures 5(a) and 5(b)) whose outer surface area is smaller than that of the wide surface portions 300.

[0047] The multiple wide surface portions 300 include a rear surface portion 3000 (see FIG. 3(b)) that is arranged opposite the connecting base portion 20, and a front surface portion 3001 (see FIG. 3(a)) that is formed to face the opposite side to the rear surface portion 3000.

[0048] The multiple narrow surface portions 301 include a wiring connection surface portion 3010 (see Figure 4(b)) formed so as to expose the terminal portion 31 (the insertion port of the terminal portion 31, which will be described later), an anti-wiring connection surface portion 3011 (see Figure 4(a)) formed so as to face the opposite side to the wiring connection surface portion 3010, and a pair of side portions (see Figures 5(a) and 5(b)) formed between the wiring connection surface portion 3010 and the wiring connection surface portion 3010.

[0049] In the following description, one of the pair of side surface portions is referred to as one side surface portion 3012 (see FIG. 5(a)), and the other of the pair of side surface portions is referred to as other side surface portion 3013 (see FIG. 5(b)).

[0050] 5(a), the rear portion 3000 is formed so that its outer surface is stepped, and the wiring connection surface portion 3010 side is located further outward in the case 30 than the anti-wiring connection surface portion 3011 side. The size of the step between the wiring connection surface portion 3010 side of the rear portion 3000 and the anti-wiring connection surface portion 3011 side of the rear portion 3000 is set to be equal to or smaller than the thickness of the connecting plate portion 200.

[0051] 3(a), the other side surface portion 3013 is formed so that its outer surface is stepped, and the wiring connection surface portion 3010 side is located further outward in the case 30 than the anti-wiring connection surface portion 3011. The size of the step between the wiring connection surface portion 3010 side of the other side surface portion 3013 and the anti-wiring connection surface portion 3011 side of the other side surface portion 3013 is set to be equal to or smaller than the thickness of the connecting plate portion 210.

[0052] As shown in FIG. 2 , the case 30 of this embodiment has a box-shaped storage section 302 with one side (front) open, and a cover section 303 that is detachable from the front of the storage section 302 and is configured to cover the open portion of the storage section 302 when attached to the front of the storage section 302.

[0053] In the case 30 of this embodiment, the storage section 302 is configured to have a rear section 3000, a wiring surface section 3010, an anti-wiring surface section 3011, one side section 3012, and the other side section 3013, and the cover section 303 is configured to have a front section 3001.

[0054] As shown in FIG. 6, the terminal portion 31 has an external connection portion 310 having an insertion port through which the transmission line L1 can be inserted and removed, and a plurality of internal connection portions 311 arranged within the case 30, the internal connection portions 311 being connected to the internal connection portions of other terminal portions 31 via relay lines L2.

[0055] In the connection device 1 of this embodiment, the multiple terminal units 31 are configured with one input terminal unit 31 and two output terminal units 31. In the drawings, the input terminal unit 31 is indicated with "(A)" after the reference numeral 31, and the output terminal unit 31 is indicated with "(B)" after the reference numeral 31.

[0056] Accordingly, the relay line L2 in this embodiment is composed of an input side relay line L20 whose end is connected to the input terminal unit 31, and a plurality of (two in this embodiment) output side relay lines L21 whose end is connected to the output terminal unit 31. The input side relay line L20 and the output side relay line L21 may be directly connected to each other, or may be connected to each other via a connector or the like.

[0057] In the terminal section 31 , the transmission line L 1 inserted into the external connection section 310 is connected to a relay line L 2 connected to the internal connection section 311 .

[0058] The external connection unit 310 shown in FIG. 6 has a transmission line L1 inserted into the socket, but if the transmission line L1 is not inserted into the socket, a plug P can be inserted instead of the transmission line L1 (see FIG. 7).

[0059] As shown in FIG. 2, the connecting structure 4 has a connecting structure body 40 and a mounting fixture 41 for mounting the connecting structure body 40 to the bracket 2.

[0060] In the connecting structure 4 of this embodiment, the mounting fixture 41 has a screw 410 and a washer 411 .

[0061] Here, the bracket side mounting portion 22 and the case side mounting portion 32 to which the connecting structure main body 40 is attached will be described.

[0062] As shown in Figure 9, the bracket side mounting portion 22 has an insertion portion 220 in which a through hole 2200 is formed that penetrates the connecting plate portion 200 in the thickness direction, and a peripheral wall portion 221 formed around the opening of the through hole 2200 on the outward surface 2001 of the connecting plate portion 200.

[0063] The peripheral wall portion 221 protrudes from an outward surface 2001 of the connecting plate portion 200. Moreover, the peripheral wall portion 221 has a curved shape along the circumferential direction with the through hole 2200 as the center.

[0064] As shown in Figure 8, the case side mounting portion 32 has a pair of back support walls 320 formed inside the storage portion 302, and a front support wall portion 321 formed on the inside of the cover portion 303 and arranged opposite the back support walls 320.

[0065] The opposing surfaces of the back support wall portion 320 and the front support wall portion 321 are formed concavely, and the connecting structure main body 40 (more specifically, the retaining portion 402 described later) is configured to be rotatably clamped between the back support wall portion 320 and the front support wall portion 321.

[0066] In this embodiment, the case side mounting portion 32 is formed on one side of the case 30 (the side opposite the wiring surface portion 3011, and the end portion on one side of the case 30 in a third direction (see FIG. 2) perpendicular to the first and second directions described below), and each of the multiple terminal portions 31 is attached to the other side of the case 30 (the side opposite the wiring surface portion 3010, and the end portion on the other side of the case 30 in the third direction (see FIG. 2)).

[0067] As shown in FIG. 2, the connecting structure main body 40 has a base 400 attached to the bracket 2 in a rotatable state about a first axis A1 extending along a first direction in which the bracket side mounting portion 22 and the case side mounting portion 32 oppose each other, a core portion 401 formed integrally with the base 400, a holding portion 402 that is integrated with the base 400 via the core portion 401 and holds the connection device main body 3 in a rotatable state about a second axis A2 extending along a second direction that intersects (orthogonal in this embodiment) with the first direction, and an interference protrusion 403 that protrudes from the core portion 401 and is formed so as to interfere with the case 30 of the connection device main body 3 that rotates about the second axis A2.

[0068] 9, the base portion 400 is formed in a cylindrical shape and extends from a core portion 401. The outer surface of the base portion 400 is formed in a stepped shape, and the outer diameter on the tip side is smaller than the outer diameter on the base side.

[0069] The tip side of the base 400 is inserted into the through hole 2200 of the insertion portion 220. In addition, the base end side of the base 400 is configured to abut against the inward surface 2000 of the connecting plate portion 200 in a state in which the tip side of the base 400 is inserted into the through hole 2200 of the insertion portion 220.

[0070] The base 400 can have the screw 410 of the mounting fixture 41 screwed into it. Therefore, when attaching the base 400 to the bracket side attachment part 22, the washer 411 is aligned with the position of the insertion part 220 and placed on the outward surface 2001 of the connecting plate part 200, the screw 410 is inserted through the washer 411 and the insertion part 220 from the outward surface 2001 side of the connecting plate part 200, and the screw 410 is screwed into the base 400, whereby the base 400 is attached to the bracket side attachment part 22.

[0071] The base 400 is configured to be rotatable about its own central axis when operated from the outside, and to maintain the rotated state due to the frictional force (static frictional force) generated between the base 400 and the connecting plate 200 when the external operation is stopped.

[0072] In this embodiment, the connecting plate portion 200 is formed with an interference portion 2002 that interferes with the outer peripheral surface of the base portion 400, and is configured so that the rotated state of the base portion 400 is maintained by the static friction force generated between the base portion 400 and the interference portion 2002.

[0073] Thus, the first axis in the connection structure 4 of this embodiment is the central axis of the base portion 400.

[0074] 2, a pair of holding portions 402 are integrally formed with the core portion 401. The pair of holding portions 402 are configured to extend from the core portion 401 in opposite directions in the second direction.

[0075] The holding portion 402 in this embodiment is formed in a shaft shape.

[0076] As shown in FIG. 8, the holding portion 402 is sandwiched between the rear receiving wall portion 320 and the front receiving wall portion 321 in a rotatable state.

[0077] Since the retaining portion 402 abuts against the opposing surfaces of the back receiving wall portion 320 and the front receiving wall portion 321, a frictional force (static frictional force) is generated between the abutting portion of the opposing surfaces of the retaining portion 402 and the back receiving wall portion 320 and the abutting portion of the opposing surfaces of the retaining portion 402 and the front receiving wall portion 321.

[0078] Therefore, when an external force is applied to the connection device main body 3, it can rotate in a circumferential direction around the holding portion 402, but when the external force is removed, the static friction force generated between the holding portion 402 and the rear support wall portion 320 and the static friction force generated between the holding portion 402 and the front support wall portion 321 causes the connection device main body 3 to maintain its position with the rotation stopped.

[0079] Thus, the second axis in the connecting structure 4 of this embodiment is the central axis of the holding portion 402.

[0080] As shown in FIGS. 9 and 10, the interference protrusion 403 is configured to interfere with the inner protrusion 33 that is a part of the case 30 when the case 30 rotates around the holding portion 402.

[0081] The tip of the interference protrusion 403 is located within the movable area of ​​the inner protrusion 33. When the inner protrusion 33 rotates together with the connection device main body 3 around the holding part, the inner protrusion 33 comes into contact with the tip of the interference protrusion 403 and rides over it.

[0082] The configuration of the connection device 1 according to this embodiment is as described above. Next, as a method of using the connection device 1, an installation method and a rotation operation of the connection device main body 3 will be described.

[0083] When installing the connection device 1, the worker selects one of the connecting plate portion 200 and the connecting plate portion 210 to be fixed to the installation location.

[0084] When the installation location is viewed from the front, the space occupied by connection device 1 changes depending on whether connecting plate portion 200 is fixed to the installation location or whether connecting plate portion 210 is fixed to the installation location. For example, if the free space at the installation location is large, connecting plate portion 200 is fixed to the installation location, and if the free space at the installation location is small, connecting plate portion 210 is fixed to the installation location.

[0085] When fixing the connecting plate portion 200 to the installation location, the worker further selects whether to fix the connecting plate portion 200 to the installation location using the screw fastening portion 2010, to fix the connecting plate portion 200 to the installation location using the adhesive portion 2011, or to fix the connecting plate portion 200 to the installation location using both the adhesive portion 2011 and the screw fastening portion 2010.

[0086] When fixing the connecting plate portion 210 to the installation location, the worker further selects whether to fix the connecting plate portion 210 to the installation location using the screw fastening portion 2110, to fix the connecting plate portion 210 to the installation location using the attachment portion 2111, or to fix the connecting plate portion 210 to the installation location using both the attachment portion 2111 and the screw fastening portion 2110.

[0087] In the following description, a case in which the connecting plate portion 200 is fixed to the installation location will be taken as an example.

[0088] When the connecting plate portion 200 is fixed to the installation location, the front portion 3001 of the case 30 faces in front of the operator (see FIG. 11).

[0089] When the connection device main body 3 is rotated around the holding portion 402 while not rotated relative to the bracket 2, the wiring surface portion 3010 can be faced toward the operator (see Figures 12(a) and 12(b)).

[0090] In addition, since the connection device main body 3 maintains the wiring surface portion 3010 facing the worker, the worker can easily perform operations on the terminal portion 31 (such as inserting and removing a plug into and from the terminal portion 31, and inserting and removing a transmission line).

[0091] Furthermore, even when the connection device main body 3 is rotated around the holding portion 402, the posture of the connection device main body 3 can be changed by rotating the connection device main body 3 around the base portion 400 (see Figures 13(a) and 13(b)).

[0092] When the connection device main body 3 is rotated about the base 400 while not rotated relative to the bracket 2, the wire connection surface 3010 can be oriented horizontally (see FIGS. 14(a) and 14(b)).

[0093] When the connection device body 3 is turned so that the wiring surface 3010 is oriented horizontally, the screw fastening portion 2010 of the coupling and fixing portion 201 that was hidden behind the connection device body 3 appears (see FIG. 14(b)).

[0094] In addition, since the connection device main body 3 is maintained with the wiring surface 3010 facing sideways, the screw fastening portion 2010 of the connecting and fixing portion 201 can be maintained in an exposed state. This makes it easy for an operator to work on the screw fastening portion 2010 of the connecting and fixing portion 201.

[0095] Furthermore, even when the connection device main body 3 is rotated around the base 400, the orientation of the connection device main body 3 can be changed by rotating the connection device main body 3 around the holding portion 402 (see Figures 15(a) and 15(b)).

[0096] In this way, the connection device 1 of this embodiment can be installed by determining the fixing manner of the bracket 2 according to the conditions of the installation location, and the orientation of the connection device main body 3 can be changed to an orientation that makes it easier for the worker to work when performing another task after the installation work.

[0097] As described above, according to the connection device 1 of this embodiment, the connection structure 4 that connects the connection device main body 3 and the bracket 2 makes the connection device main body 3 rotatable in the circumferential direction about the first axis and the circumferential direction about the second axis. Therefore, with the bracket 2 fixed to the installation location, the orientation of the connection device main body can be changed by rotating the connection device main body 3 in the circumferential direction about the first axis and the circumferential direction about the second axis.

[0098] Therefore, connection device 1 makes it easier to orient connection device body 3 in a direction suitable for work, thereby achieving the excellent effect of improving workability.

[0099] In addition, the connection device main body 3 has one end in the third direction rotatably connected to the bracket 2 by the connecting structure 4, and the terminal portion 31 is attached facing outward to the other end in the third direction, so that when the connection device main body 3 is rotated, the terminal portion 31 can easily be faced toward the worker, thereby improving the convenience of working on the terminal portion 31.

[0100] Furthermore, the connection device main body 3 can be rotated around the holding portion 402 even after it has rotated around the base 400, and can be rotated around the base 400 even after it has rotated around the holding portion 402.Furthermore, the operation of rotating the connection device main body 3 around the base 400 and the operation of rotating it around the holding portion 402 can be performed simultaneously, making it easy to use.

[0101] Furthermore, the rotated connection device main body 3 is configured to maintain the rotated state whether the transmission line L1 is connected to the terminal portion 31 or not. Therefore, even if the worker releases the rotated connection device main body 3, the posture of the connection device main body 3 is maintained, improving the convenience of working on the connection device main body 3.

[0102] Furthermore, when the connection device 1 is installed at the installation location, if the anti-slip portion 202 of the connecting base portion 20 and the anti-slip portion 212 of the connecting base portion 21 abut against the installation location, the movement of the bracket 2 relative to the installation location is restricted, so that when the connection device main body 3 is rotated, the bracket 2 can be prevented from moving in conjunction with the connection device main body 3, making it easier to rotate the connection device main body 3.

[0103] In the connection device 1 of this embodiment, the wide surface portion 300 and the narrow surface portion 301 of the connection device main body 3 are formed with different widths, and the connecting plate portion 200 and the linked plate portion 210 are also formed with different widths to match the wide surface portion 300 and the narrow surface portion 301 of the connection device main body 3, thereby improving convenience during installation work.

[0104] More specifically, in connection device 1, the width (thickness) of narrow surface portion 301 of connection device main body 3 when viewed from the front is smaller than the width (horizontal width) of wide surface portion 300 of connection device main body 3 when viewed from the front, and the width of inward surface 2100 of connecting plate portion 210 when viewed from the front is smaller than the width of inward surface 2000 of connecting plate portion 200 when viewed from the front. Therefore, the space occupied by connection device 1 when the installation location is viewed from the front differs between when connecting plate portion 200 is fixed to the installation location and when connecting plate portion 210 is fixed to the installation location.

[0105] Furthermore, during installation work, it is possible to choose whether to fix the connecting plate portion 200 or the adjacent plate portion 210 to the installation location depending on the size of the installation location when viewed from the front, thereby improving convenience during installation work.

[0106] Furthermore, in case 30, the outer surface of rear portion 3000 is formed in a stepped shape, and the size of the step between the wiring surface portion 3010 side of rear portion 3000 and the anti-wiring surface portion 3011 side of rear portion 3000 is set to be less than the thickness of connecting plate portion 200, so that outward surface 2001 of connecting plate portion 200 is positioned outside the outer surface of rear portion 3000.

[0107] Therefore, when the connecting base portion 20 is attached to the installation location with the outward surface 2001 of the connecting plate portion 200 facing the installation location, the rear portion 3000 of the case 30 is not in contact with the installation location, thereby preventing the rear portion 3000 of the case 30 from interfering with the installation location and preventing the rotational movement of the connection device main body 3 from being hindered.

[0108] In addition, in the case 30, the outer surface of the other side portion 3013 is also formed to be stepped, and the size of the step between the wiring connection surface portion 3010 side of the other side portion 3013 and the anti-wiring connection surface portion 3011 side of the other side portion 3013 is set to be less than the thickness of the connecting plate portion 210, so that the outward surface 2101 of the connecting plate portion 210 is positioned outer than the outer surface of the other side portion 3013.

[0109] Therefore, when the connecting base portion 21 is attached to the installation location with the outward surface 2101 of the connecting plate portion 210 facing the installation location, the other side portion 3013 of the case 30 is not in contact with the installation location, thereby preventing the other side portion 3013 of the case 30 from interfering with the installation location, and thereby preventing the rotational operation of the connection device main body 3 from being hindered.

[0110] In addition, since it is possible to select whether to fix both the connecting plate portion 200 and the connecting plate portion 210 to the installation location by screwing or by gluing, ease of use during installation is further improved.

[0111] Furthermore, the holding portion 402 of the connecting structure 4 rotatably holds the connection device main body 3 on the anti-wiring surface portion 3011 side opposite the wiring surface portion 3010 that exposes the insertion port of the terminal portion 31, making it easier to face the insertion port of the terminal portion 31 toward the worker, thereby improving workability.

[0112] The transmission line connection device according to the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the spirit and scope of the present invention.

[0113] Although the connection device 1 in the above embodiment is configured to connect an optical communication cable as the transmission line L1, the present invention is not limited to this configuration. For example, the connection device 1 may be configured to connect a broadcast line as the transmission line L1, or may be configured to connect a communication line or a power line.

[0114] In the above embodiment, the attachment part 2011 of the connecting and fixing part 201 is configured by a magnet, but is not limited to this configuration. For example, the attachment part 2011 of the connecting and fixing part 201 may be configured by a suction cup or an adhesive.

[0115] In the above embodiment, the attachment portion 2111 of the connecting and fixing portion 211 is configured by a magnet, but is not limited to this configuration. For example, the attachment portion 2111 of the connecting and fixing portion 211 may be configured by a suction cup or an adhesive.

[0116] In the connection device 1 of the above embodiment, the base 400 is formed in an axial shape, and the bracket side attachment portion 22 is configured to function as a bearing, but the present invention is not limited to this configuration. For example, the connection device 1 may be configured such that the bracket side attachment portion 22 is formed in an axial shape, and the base 400 functions as a bearing.

[0117] In the connection device 1 of the above embodiment, the holding portion 402 is formed in an axial shape, and the case side attachment portion 32 is configured to function as a bearing, but the present invention is not limited to this configuration. For example, the connection device 1 may be configured such that the case side attachment portion 32 is formed in an axial shape, and the holding portion 402 functions as a bearing.

[0118] The connecting structure 4 in the above embodiment is configured to be able to stop the rotation of the connection device body 3 by the static friction force generated between the base 400 and the connecting plate 200 (specifically, the interference portion 2002) and the static friction force generated between the holding portion 402 and the front receiving wall 321, but is not limited to this configuration. For example, the connecting structure 4 may be configured to be able to stop the rotation of the connection device body 3 by the base 400 engaging with the connecting plate 200 or the holding portion 402 engaging with the front receiving wall 321.

[0119] In the connecting structure 4 of the above embodiment, the base 400 and the holding part 402, which are the rotation center of the connection device body 3, are formed in an axial shape, but the present invention is not limited to this configuration. For example, the connecting structure 4 may have a ball joint as a configuration that is the rotation center of the connection device body 3.

[0120] In this way, the connection device main body 3 can perform movements equivalent to the rotational movement about the first axis described in the description of the connecting structure 4 of the above embodiment, and movements equivalent to the rotational movement about the second axis, and can also easily perform movements other than these rotational movements, improving usability.

[0121] Although the connection device 1 in the above embodiment is configured to connect one input transmission line L1 and two output transmission lines L1, the present invention is not limited to this configuration.

[0122] For example, the connection device 1 may be configured to connect one input transmission line L1 and four output transmission lines L1 (see FIG. 16), or the connection device 1 shown in FIG. 16 may have multiple terminal sections 31 configured with one input terminal section 31 and four output terminal sections 31.

[0123] In addition, the connection device 1 may be configured to connect one input transmission line L1 and eight output transmission lines L1 (see FIG. 17), or the connection device 1 shown in FIG. 17 may have multiple terminal sections 31 configured with one input terminal section 31 and eight output terminal sections 31.

[0124] Furthermore, the connection device main body 3 may be configured to have an external case 34 provided on the outer surface of the case 30 as shown in Fig. 17 depending on the number of terminal parts 31. The case 30 and the external case 34 may be integrally molded or may be configured as separate bodies.

[0125] The connecting base portion 21 in the above embodiment is configured to be disposed opposite the other side surface portion 3013 of the plurality of narrow surface portions 301, but is not limited to this configuration. For example, the connecting base portion 21 may be configured to be disposed opposite one side surface portion 3012 of the plurality of narrow surface portions 301, as shown in FIG.

[0126] Connection device 1 shown in FIG. 18 is obtained by horizontally inverting the shape and structure of connection device 1 shown in FIG.

[0127] The connection device 1 shown in FIG. 16 may also be configured, like the connection device 1 shown in FIG. 19, so that the connecting base portion 21 is arranged opposite one side portion 3012 of the multiple narrow surface portions 301, and the connection device 1 shown in FIG. 17 may also be configured, like the connection device 1 shown in FIG. 20, so that the connecting base portion 21 is arranged opposite one side portion 3012 of the multiple narrow surface portions 301.

[0128] Furthermore, although not specifically mentioned in the description of the connection device 1 of the above embodiment, the layout of the external connection unit 310 can also be reversed left to right as shown in FIG.

[0129] Similarly, the layout of the portion connection section 310 of the connection device 1 shown in FIG. 16 can be reversed left to right, like the connection device 1 shown in FIG. 19, and the layout of the portion connection section 310 of the connection device 1 shown in FIG. 17 can be reversed left to right, like the connection device 1 shown in FIG. 20.

[0130] Figure 14(b), which was referred to in the explanation of the connection device 1 of the above embodiment, illustrates a state in which the screw fastening portion 2010 of the connecting fixing portion 201, which was hidden behind the connection device body 3, is revealed when the wiring surface portion 3010 of the connection device body 3 is oriented straight to the side. However, the orientation of the wiring surface portion 3010 of the connection device body 3 that can expose the entire screw fastening portion 2010 is not limited to a state in which the wiring surface portion 3010 of the connection device body 3 is oriented straight to the side, and changes depending on the size, etc. of the connection device body 3 and the formation position of the screw fastening portion 2010, etc.

[0131] Although not specifically mentioned in the description of the connection device 1 of the above embodiment, the layout of the trunk lines L2 shown in FIG. 6 is merely an example, and is not limited to the layout shown in FIG.

[0132] Although not specifically mentioned in the description of the interference portion 2002 in the above embodiment, the shape of the interference portion 2002 is not particularly limited as long as it is possible to generate a static friction force between the base portion 400 and the interference portion 2002 .
