Description

Technical Field

[0001] This invention relates to assistive tools.

[0002] This application claims priority based on Japanese Patent Application No. 2023-213865, filed in Japan on December 19, 2023, the contents of which are incorporated herein by reference. Background Technology

[0003] In recent years, the miniaturization and high density of connectors in data centers have been developing. Along with this, there is a desire to improve the efficiency of connecting or disconnecting connectors by operating multiple connectors simultaneously. For example, Patent Document 1 discloses a structure capable of simultaneously disconnecting four connectors.

[0004] Patent Document 1: U.S. Patent Application Publication No. 2019 / 285806

[0005] In the structure of Patent Document 1, while multiple connectors can be disconnected simultaneously, they cannot be connected simultaneously. Therefore, additional tools are required, for example, to connect them simultaneously. Preparing additional tools for both connection and disconnection operations leads to reduced operational efficiency. Summary of the Invention

[0006] This invention was made with the consideration of such a situation in mind, and its purpose is to provide an auxiliary tool that can connect and disconnect multiple connectors at the same time.

[0007] To address the aforementioned issues, Embodiment 1 of the present invention is an auxiliary tool used to connect multiple connectors to an adapter, comprising: a first housing; and a second housing capable of relative movement with respect to the first housing. The first housing includes: a first opening facing the adapter, allowing the front ends of the multiple connectors to protrude towards the adapter; a second opening facing the second housing; and a swingable portion having multiple release portions that abut against the contact portions of the multiple connectors when the first housing is separated from the adapter. The multiple release portions are arranged in a side-by-side direction, and the swing center of the swing portion is located at the end of the swing portion in the side-by-side direction. If the front end of the swing portion swings away from the contact portions of the connectors, a torque is applied to the swing portion to swing it in the direction of pulling the connectors out of the adapter.

[0008] The second embodiment of the present invention is an auxiliary tool completed based on the auxiliary tool involved in the first embodiment, wherein the swinging part is integrally formed with the first housing.

[0009] The third embodiment of the present invention is an auxiliary tool completed based on the auxiliary tool involved in the first or second embodiment, wherein the plurality of release parts protrude from the swing part toward the second housing.

[0010] The fourth embodiment of the present invention is an auxiliary tool completed based on the auxiliary tool involved in any of the embodiments 1 to 3, wherein the second housing has a plurality of pressing parts that press the plurality of connectors toward the adapter, and the positions of the plurality of pressing parts are different from each other in the direction in which the first housing and the second housing move relative to each other.

[0011] The fifth embodiment of the present invention is an auxiliary tool completed based on the auxiliary tool involved in the fourth embodiment, wherein the first housing has a plurality of engagement release parts, which release the plurality of pressing parts from contact with the plurality of connectors.

[0012] According to the above-described manner of the present invention, an auxiliary tool can be provided that can connect and disconnect multiple connectors simultaneously. Attached Figure Description

[0026] Hereinafter, the auxiliary tool and the connector with the auxiliary tool of this embodiment will be described with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the connector 2 with auxiliary tool includes an auxiliary tool 1 and multiple connectors 100A to 100D. The auxiliary tool 1 includes a first housing 10 and a second housing 20. The auxiliary tool 1 is configured to position the multiple connectors 100A to 100D relative to the adapter 3 (see reference). Figure 8 Connecting and disconnecting together. Data center outlet panels (not shown) typically have a large number of closely spaced adapters 3. Each connector 100A~100D has a ferrule 110. The ferrule 110 has a connection end face 112 that exposes the optical fiber.

[0028] (Direction definition)

[0029] In this embodiment, the direction in which the first housing 10 and the second housing 20 are arranged is called the length direction Z. The length direction Z is consistent with the direction in which the plurality of fiber optic holes 111 extend. The direction in which the plurality of connectors 100 (the plurality of connectors 100A~100D) are arranged is called the side-by-side direction Y or the left-right direction. The side-by-side direction Y is orthogonal to the length direction Z. The direction orthogonal to both the length direction Z and the side-by-side direction Y is called the up-down direction X or the orthogonal direction. The side of the connection end face 112 (+Z side) in the length direction Z is called the front or front end side. The side opposite to the +Z side in the length direction Z (-Z side) is called the rear or base end side. The side in the up-down direction X (+X side) is called the upper side. The side opposite to the +X side in the up-down direction X (-X side) is called the lower side. The side in the side-by-side direction Y (+Y side) is called the left side. The side opposite to the +Y side in the side-by-side direction Y (-Y side) is called the right side. However, the up-down direction X may not be consistent with the vertical direction. The view taken from the vertical direction (X) is called a top view, and the view taken from the horizontal direction (Y) is called a side view.

[0030] The connector 2 with auxiliary tools in this embodiment has four connectors 100A to 100D. These connectors 100A to 100D are sometimes referred to as first connector 100A, second connector 100B, third connector 100C, and fourth connector 100D in order from the -Y side to the +Y side. However, since the construction of each connector 100A to 100D is identical, they are simply referred to as connector 100 without distinction. The number of connectors 100 in the connector 2 with auxiliary tools is not limited to four and can be varied from four.

[0031] like Figure 2 , Figure 3 As shown, the first housing 10 has a first opening 11, a second opening 12, a swing portion 13, a support surface 15, and two locking portions 16. The first opening 11 faces the front end side. A plurality of connectors 100 (the front ends of the plurality of connectors 100) protrude from the first opening 11. The second opening 12 faces the second housing 20. The swing portion 13 extends in the parallel direction Y. The swing portion 13 may extend along the parallel direction Y (parallel to the parallel direction Y) or may not extend along the parallel direction Y (parallel to the parallel direction Y). The swing portion 13 is capable of swinging about a swing center 13a. The swing portion 13 is capable of elastically deforming in the length direction Z with the swing center 13a as a base point. In this embodiment, the swing center 13a is located at the end of the swing portion 13 in the parallel direction Y (the end on the -Y side). The end of the swing portion 13 on the side opposite to the swing center 13a in the parallel direction Y (the end on the +Y side) is referred to as the front end portion 13b. In this embodiment, the first housing 10, including the swing portion 13, is integrally formed. The swing center 13a is connected to the portion of the first housing 10 other than the swing portion 13. If a force in the length direction Z is applied to the swing portion 13, the swing portion 13 elastically deforms and swings around the swing center 13a.

[0032] Multiple release portions 14a-14d are formed in the swing portion 13. The number of release portions 14a-14d is the same as the number of connectors 100 installed on the auxiliary tool 1 (four in this embodiment). Release portions 14a-14d have the function of releasing the connection of the connector 100 to the adapter 3. Each release portion 14a-14d corresponds to one connector 100. Hereinafter, these release portions will sometimes be referred to as the first release portion 14a, the second release portion 14b, the third release portion 14c, and the fourth release portion 14d.

[0033] Release portions 14a-14d are arranged at intervals along the parallel direction Y. The positions of release portions 14a-14d in the parallel direction Y correspond to the positions of connectors 100A-100D in the parallel direction Y. Release portions 14a-14d protrude from the swing portion 13 toward the base end side towards the second housing 20. Viewed from the vertical direction X, release portions 14a-14d are arc-shaped protrusions toward the base end side. However, release portions 14a-14d can also be triangular.

[0034] The support surface 15 is configured to face the swing portion 13 in the longitudinal direction Z. The support surface 15 is inclined toward the front end side (+Z side) as it moves away from the swing center 13a in the parallel direction Y. The support surface 15 serves to support the swing portion 13 when it swings toward the front end side with its front end 13b away from the fourth connector 100D (the second abutment portion 142 of the fourth connector 100D described later). Due to the presence of the support surface 15, excessive swinging of the swing portion 13 can be suppressed.

[0035] like Figure 3 As shown, the two locking portions 16 are arranged with a gap in the side-by-side direction Y. The locking portions 16 extend from the second opening 12 toward the base end side. A locking protrusion 16a is formed at the base end of each locking portion 16. The locking protrusion 16a protrudes from the locking portion 16 toward the inward side in the side-by-side direction Y. A plurality of engagement release portions 17 are formed at the lower end of the first housing 10. The number of engagement release portions 17 is the same as the number of connectors 100 installed on the auxiliary tool 1 (4 in this embodiment). The engagement release portions 17 extend from the second opening 12 toward the base end side.

[0036] like Figure 4 , Figure 5 As shown, the second housing 20 has a second main body 21 and a plurality of pressing portions 22-25. The second main body 21 is a cylindrical shape extending along the length direction Z and having a rectangular cross-section. A plurality of connectors 100 are inserted into the inner side of the second main body 21. Two guide grooves 21a are formed in the second main body 21. The guide grooves 21a are recessed from both sides of the second main body 21 (the sides facing the +Y and -Y sides) toward the inner side in the parallel direction Y. The guide grooves 21a extend linearly from the end of the front end side of the second main body 21 toward the base end side. A locking hole 21b is formed on the inner surface of each guide groove 21a. The locking hole 21b penetrates the second main body 21 in the parallel direction Y. The locking hole 21b extends along the length direction Z inside the guide groove 21a.

[0037] With the first housing 10 and the second housing 20 assembled, the locking portion 16 of the first housing 10 enters the guide groove 21a of the second housing 20. Furthermore, the locking protrusion 16a enters the inner side of the locking hole 21b. When the first housing 10 and the second housing 20 move relative to each other in the longitudinal direction Z, the locking portion 16 and the guide groove 21a slide. Because the locking protrusion 16a is located within the locking hole 21b, the movement of the first housing 10 relative to the second housing 20 towards the front end is restricted beyond a predetermined range.

[0038] like Figure 5 As shown, the pressing part 22 has two protrusions 22a. The pressing parts 23-25 ​​also each have two protrusions 23a-25a. That is, pressing part 23 has two protrusions 23a, pressing part 24 has two protrusions 24a, and pressing part 25 has two protrusions 25a. The pressing parts 22-25 protrude upwards from the lower end (the end on the -X side) of the second main body 21 (the upper side). The number of pressing parts 22-25 is equal to the number of connectors 100 included in the connector 2 with auxiliary tools. In this embodiment, there are four pressing parts 22-25 and four connectors 100. Hereinafter, the four pressing parts will sometimes be referred to as the first pressing part 22, the second pressing part 23, the third pressing part 24, and the fourth pressing part 25. The positions of the pressing parts 22-25 in the Z-direction of their length are different from each other. The third pressing part 24 is located at the foremost end. The second pressing part 23 is located on the front end side, and the third pressing part 23 is located on the front end side. The fourth pressing part 25 is located on the base end side.

[0039] like Figure 6 , Figure 7 As shown, each connector 100 has a ferrule 110, a housing 120, a snap-fit ​​protrusion 131, and a protective cover 140. The connector 100 in this embodiment is a male-side connector with two positioning pins 102. These positioning pins 102 are inserted inside the adapter 3 into positioning holes in the ferrule of the female-side connector (not shown). Thus, the two connectors are positioned to match. Furthermore, the multiple connectors 100 included in the connector 2 with auxiliary tools can also be female-side connectors. That is, the connector 100 may not have positioning pins 102.

[0040] like Figure 7 As shown, the ferrule 110 has multiple fiber optic holes 111. Optical fibers (not shown) are inserted into these fiber optic holes 111. The optical fiber has a glass portion and a cladding layer covering the glass portion. A force-applying member 113 is disposed inside the housing 120 to apply force to the ferrule 110. The force-applying member 113 is, for example, a helical spring. The ferrule 110 has a connection end face 112 for the exposed optical fiber. Through the force of the force-applying member 113, the connection end face 112 abuts against the connection end faces of other connectors inside the adapter 3. Thus, the two connectors are optically connected.

[0041] like Figure 7 As shown, connector 100 includes a resilient sheet 130. The resilient sheet 130 has a engaging protrusion 131. However, the engaging protrusion 131 may also be part of other components (housing 120, shield 140, etc.) included with connector 100. The resilient sheet 130 is formed, for example, by a leaf spring and is resilient. The engaging protrusion 131 has an engaging hole 3c that enters into the adapter 3 (see reference). Figure 8 The inner side of the cover 140 is used to engage the connector 100 with the adapter 3. The cover 140 includes two parts (cover body 140a and movable part 140b). A retaining space for retaining the elastic piece 130 is formed on the inner side of the movable part 140b.

[0042] like Figure 6 As shown, the cover 140 has an abutment piece 141. The abutment piece 141 is formed at the lower end of the cover body 140a. The abutment piece 141 protrudes downward from the lower surface of the cover body 140a and extends towards the base end. The abutment piece 141 is elastically deformable in the vertical direction X with the connection portion with the cover body 140a (the end of the front end of the abutment piece 141) as the base point. Two first abutment portions 141a and one abutment release portion 141b are formed on the abutment piece 141. The first abutment portions 141a protrude from the abutment piece 141 towards both sides in the side-by-side direction Y. The abutment release portion 141b protrudes downward from the abutment piece 141.

[0043] The two first abutment portions 141a and the pressing portions 22-25 corresponding to the connectors 100A-100D (see reference) Figure 5 The first abutment portions 141a of the first connector 100A are opposite to the two protrusions 22a of the first pressing portion 22. During connection, the connectors 100A-100D are pressed toward the adapter 3 by the pressing portions 22-25 abutting against each of the first abutment portions 141a. The abutment release portion 141b and the engagement release portion 17 are opposite to each other in the length direction Z. The surface of the abutment release portion 141b that faces the engagement release portion 17 is inclined toward the front end side as it faces upward. The function of the abutment release portion 141b will be described later.

[0044] like Figure 7 As shown, each connector 100 has a second abutment portion 142 in its cover 140. The second abutment portion 142 is provided at the upper end of the cover 140. Each second abutment portion 142 is opposite to the release portions 14a to 14d in the longitudinal direction Z.

[0045] Next, use Figure 8 The functions of the auxiliary tool 1, configured as described above, and the connector 2 equipped with the auxiliary tool will be explained. Furthermore, in Figure 8Only one adapter 3 is shown, but in actual data centers and other environments, a large number of adapters 3 are densely packed on power strips. Additionally, in Figure 8 The connector on the object side is not shown, but the connector on the object side can also be connected to the adapter 3 from the second insertion port 3b.

[0046] <Connection Operation>

[0047] When performing connection operations, such as Figure 8 As shown, the connector 2 with the auxiliary tool is brought closer to the adapter 3. More specifically, the second housing 20 is held to allow the multiple connectors 100 to enter the first insertion port 3a of the adapter 3. If the connectors 100 are partially inserted into the first insertion port 3a, the first housing 10 abuts against the adapter 3. If the second housing 20 is further pressed toward the adapter 3, the second housing 20 moves relative to the first housing 10 toward the front end side (+Z side). At this time, the locking part 16 and the guide groove 21a slide, and the relative movement of the first housing 10 and the second housing 20 is guided.

[0048] As the second housing 20 and the first housing 10 move relative to each other, the third pressing part 24 (refer to the one at the foremost side of the plurality of pressing parts 22-25) is activated. Figure 5 The protrusion 24a of the third connector 100C first abuts against the first contact portion 141a (see reference). Figure 6 (arrival) Figure 9 The diagram shows the state where the protrusion 24a abuts against the first abutment portion 141a. If the second housing 20 is further pressed in, a force towards the front end is transmitted to the connector 100 via the first abutment portion 141a. At this moment, the first pressing portion 22, the second pressing portion 23, and the fourth pressing portion 25 separate from the first abutment portions 141a of each connector 100A, 100B, and 100D. That is, only the third pressing portion 24 presses the third connector 100C towards the front end. Therefore, the operating force applied by the user to the second housing 20 is approximately the same as the force required to press a connector 100 into the adapter 3.

[0049] If the third pressing part 24 presses the third connector 100C in by a predetermined amount, the engaging protrusion 131 of the third connector 100C engages with the engaging hole 3c of the adapter 3. Thus, the connection between the third connector 100C and the adapter 3 is completed. If the user further presses the second housing 20, the engaging release part 17 abuts against the abutment release part 141b, thereby causing the abutment piece 141 to elastically deform towards the +X side (see reference). Figure 10 Therefore, the contact between the third pressing part 24 and the first abutting part 141a is released.

[0050] Subsequently, the user continues to press the second housing 20 toward the adapter 3. As a result, the second pressing part 23, located on the front end of the plurality of pressing parts 22-25, comes into contact with the first abutting part 141a of the second connector 100B. Then, by pressing the second pressing part 23 into the second connector 100B, the engaging protrusion 131 engages with the engaging hole 3c. Furthermore, the contact between the second pressing part 23 and the first abutting part 141a of the second connector 100B is released by the corresponding engaging release part 17.

[0051] Subsequently, the fourth pressing part 25 and the first pressing part 22 are also pressed sequentially toward the front end towards the corresponding fourth connector 100D and first connector 100A. That is, by pressing in the second housing 20, all four connectors 100 can be connected to the adapter 3 at the same time. Furthermore, assuming that the operating force required to connect all four connectors 100 to the adapter 3 simultaneously is more than four times that required to connect only one connector 100 to the adapter 3, in this embodiment, the multiple pressing parts 22-25 connect each connector 100 to the adapter 3 at different times. Therefore, the operating force required for simultaneous connection is reduced.

[0052] Next, the connection disconnection operation will be explained. According to the auxiliary tool 1 of this embodiment, multiple connectors 100 can be disconnected from the adapter 3 at the same time.

[0053] Specifically, such as Figure 11 As shown, the second housing 20 is pulled towards the base end (-Z side) from a state where multiple connectors 100 are connected to the adapter 3. If the second housing 20 moves towards the base end relative to the first housing 10, the locking protrusion 16a of the first housing 10 reaches the end of the front end of the locking hole 21b of the second housing 20, and a force towards the base end is also transmitted to the first housing 10. If the first housing 10 moves towards the base end, the release parts 14a to 14d abut against the second abutment parts 142 of each connector 100.

[0054] If the first housing 10 moves further towards the base end side, then as Figure 12 As shown, the swinging part 13 swings forward at its end 13b in the direction of separation from the fourth connector 100D (the second abutment part 142 of the fourth connector 100D). As a result, the release parts 14b-14d do not abut against the connectors 100B-100D, and only the first release part 14a abuts against the second abutment part 142 of the first connector 100A. Therefore, the operating force required for the user to pull the second housing 20 is approximately the same as the force required to pull only one first connector 100A from the adapter 3.

[0055] Here, the swinging part 13 elastically deforms when it swings around the swinging center 13a. If the swinging part 13 elastically deforms in this way, a torque is generated that causes the swinging part 13 to swing in the direction of pulling out the connectors 100A to 100D from the adapter 3.

[0056] If the user pulls the second housing 20 further, the first connector 100A, whose second abutment portion 142 has been pressed by the first release portion 14a, is pulled out of the adapter 3. At this time, the engaging protrusion 131 of the first connector 100A disengages from the engaging hole 3c of the adapter 3, thereby releasing the force exerted on the first connector 100A by the first release portion 14a towards the base end. In other words, the reaction force received by the first release portion 14a from the first connector 100A is also released. The torque continues to act on the swing portion 13, causing the swing portion 13 to swing around the swing center 13a, and the second release portion 14b abuts against the second abutment portion 142 of the second connector 100B.

[0057] The second release part 14b, through the same action as the first release part 14a, pulls the second connector 100B out of the adapter 3. Then, the reaction force received by the second release part 14b from the second connector 100B is released, the swing part 13 swings around the swing center 13a, and the third release part 14c abuts against the second abutting part 142 of the third connector 100C. Thereafter, the same action is repeated, and the third connector 100C and the fourth connector 100D are also pulled out of the adapter 3.

[0058] That is, by pulling the second housing 20, all four connectors 100 can be disconnected from the adapter 3 at the same time. Furthermore, assuming that the operating force required to disconnect all four connectors 100 from the adapter 3 simultaneously is more than four times that required to disconnect only one connector 100, in this embodiment, multiple disconnection parts 14a-14d disconnect each connector 100 from the adapter 3 at different times. Therefore, the operating force required for simultaneous disconnection is reduced.

[0059] As described above, the auxiliary tool 1 of this embodiment is used to connect multiple connectors 100 to the adapter 3. The auxiliary tool 1 includes: a first housing 10; and a second housing 20, which is movable relative to the first housing 10. The first housing 10 includes: a first opening 11 facing the adapter 3, allowing the front ends of the multiple connectors 100 to protrude towards the adapter 3; a second opening 12 facing the second housing 20; and a swingable swing portion 13. The swing portion 13 has multiple release portions 14a to 14d, which abut against the contact portions (second contact portions) 142 of the multiple connectors 100A to 100D respectively when the first housing 10 is separated from the adapter 3, and the multiple release portions 14a to 14d are arranged in a side-by-side direction Y. The swing center 13a of the swing part 13 is located at the end of the swing part 13 in the parallel direction Y. If the front end 13b of the swing part 13 swings away from the abutment part (second abutment part) 142 of the connector 100, a torque that causes the swing part 13 to swing in the direction of pulling the connector 100 out of the adapter 3 is applied to the swing part 13.

[0060] According to this auxiliary tool 1, multiple connectors 100A to 100D can be connected and disconnected from the adapter 3 together. Furthermore, multiple release parts 14a to 14d formed in the swing part 13 can be used to pull the multiple connectors 100 out of the adapter 3 one by one. Therefore, compared to pulling the multiple connectors 100 out of the adapter 3 simultaneously, the required operating force can be reduced.

[0061] Furthermore, the swing portion 13 is integrally formed with the first housing 10. Therefore, compared to the case where the swing portion 13 and the first housing 10 are separate, the number of parts can be reduced.

[0062] Furthermore, multiple release portions 14a-14d protrude from the swing portion 13 toward the second housing 20. This facilitates the transmission of force toward the base end from the release portions 14a-14d to the connectors 100A-100D. Consequently, the connectors 100A-100D can be pulled out more smoothly.

[0063] Furthermore, the second housing 20 has multiple pressing portions 22-25 that press the multiple connectors 100A-100D toward the adapter 3. The positions of the multiple pressing portions 22-25 are different from each other in the direction of relative movement (length direction Z) between the first housing 10 and the second housing 20. Therefore, each connector 100A-100D can be pressed relative to the adapter 3 at different times. Thus, compared to pressing multiple connectors simultaneously, the maximum operating force can be reduced.

[0064] In addition, the first housing 10 has a plurality of engagement release parts 17, which release the plurality of pressing parts 22-25 from contact with the plurality of connectors 100A-100D. As a result, it is possible to prevent pressing pressure from continuing to act on the connectors 100 to which the connection to the adapter 3 has been completed.

[0065] Furthermore, the technical scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0066] For example, the swing portion 13 may be formed separately from the first housing 10. Furthermore, the torque acting on the swing portion 13 may be generated by means other than elastic deformation of the swing portion 13. For example, a torsion coil spring or similar device may be installed on the swing portion 13, which is separate from the first housing 10, to generate the torque.

[0067] In addition, without departing from the spirit of the present invention, the constituent elements in the above embodiments can be appropriately replaced with known constituent elements. Furthermore, the above embodiments and variations can be appropriately combined.
