[0001] This disclosure relates to a cable arrangement clamp and a method for inspecting multi-core cables. Background Technology

[0005] Patent Document 1: Japanese Patent Application Publication No. 2000-35456 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] As a method for checking which cable at one end of a multi-core cable corresponds to which cable at the opposite end, consider the following method.

[0008] First, prepare Figure 18 , Figure 19 The cable arranging clamp 101 shown has multiple slots 103.

[0009] Next, at one end of the multi-core cable, the multiple cables 105 included in the multi-core cable are arranged using a cable arranging clamp 101. That is, one cable 105 is pressed into each groove 103. At this time, while pressing the cable 105 into the groove 103 using a pressing member (not shown), the pressing member is slid along the length direction L of the groove 103.

[0010] Next, as Figure 18 , Figure 19 As shown, electrode unit 107 is positioned opposite cable arrangement clamp 101. Electrode unit 107 includes support plate 109 and multiple electrodes 111. The multiple electrodes 111 are spaced apart on the lower surface of support plate 109. Each electrode 111 is opposite a cable 105.

[0011] Next, an AC electrical signal is input from the opposing electrode 111 to one of the cables 105 held by the cable arrangement clamp 101. Simultaneously, at the opposite ends of the multi-core cable, processing is performed to detect output signals from each of the multiple cables 105. The cable 105 that detects an output signal corresponds to the cable 105 that received an input electrical signal.

[0012] Consider using an insulator such as rubber to construct the cable arranging clamp 101. However, when the cable arranging clamp 101 is constructed of an insulator, repeated sliding of the pressing member along the length L of the groove 103 causes wear on the surface 101A of the cable arranging clamp 101, resulting in a shallower groove 103. Furthermore, the inner surface 103A of the groove 103 is worn by the cable 105, causing the width of the groove 103 to widen. As a result, it becomes difficult to use the cable arranging clamp 101 to arrange the cable 105.

[0013] Furthermore, consider using copper foil etched onto a printed circuit board to form grooves 103 to manufacture the cable arrangement fixture 101. However, in this case, the voltage of the output signal detected at the opposite end of the multi-core cable (hereinafter referred to as the detection voltage) becomes smaller. If the detection voltage becomes smaller, the inspection accuracy of the multi-core cable decreases. The reason for the decrease in detection voltage is as follows: stray capacitance is generated between one electrode 111 and the adjacent electrode 111 via the copper foil of the cable arrangement fixture 101.

[0014] One aspect of this disclosure is to provide a cable arrangement clamp that can suppress the shallowing of the groove due to wear and can increase the detection voltage, as well as an inspection method for multi-core cables.

[0015] Solution for solving the problem

[0016] One aspect of this disclosure is a cable arranging clamp for arranging multiple cables included in a multi-core cable. The clamp includes a slot forming portion having multiple slots for holding the cables. The slot forming portion includes a support member made of an insulator and multiple metal members spaced apart on the surface of the support member. The slot is formed by the support member and two adjacent metal members. Two adjacent metal members are electrically insulated in the width direction of the slot.

[0017] In the cable arranging fixture of this disclosure, at least the portion of the surface of the groove forming part adjacent to the groove is made of a metal component. Therefore, the cable arranging fixture of this disclosure can prevent the groove from becoming shallow due to wear.

[0018] In the cable arrangement clamp of this disclosure, two adjacent metal parts are electrically insulated in the width direction of the slot. Therefore, no stray capacitance is generated between the electrode and its adjacent electrode via the metal parts of the cable arrangement clamp. As a result, the cable arrangement clamp of this disclosure can increase the detection voltage.

[0019] Another aspect of this disclosure is a cable arranging clamp for arranging multiple cables included in a multi-core cable, comprising a slot forming portion having multiple slots for holding the cables. The slot forming portion includes multiple metal members having the slots formed therein. The multiple metal members are spaced apart in the width direction of the slots. Adjacent metal members in the width direction of the slots are electrically insulated.

[0020] In another embodiment of the cable arrangement fixture disclosed herein, at least the portion of the surface of the groove forming part adjacent to the groove is made of a metal component. Therefore, this other embodiment of the cable arrangement fixture can prevent the groove from becoming shallower due to wear.

[0021] In the cable arrangement clamp, which is another embodiment of this disclosure, two adjacent metal parts are electrically insulated in the width direction of the slot. Therefore, no stray capacitance is generated between the electrode and its adjacent electrode via the metal parts of the cable arrangement clamp. As a result, the cable arrangement clamp, as another embodiment of this disclosure, can increase the detection voltage.

[0022] Another aspect of this disclosure is a method for inspecting a multi-core cable, wherein at one end of the multi-core cable, a cable arranging fixture is used to arrange the multiple cables included in the multi-core cable, an AC electrical signal is input to one of the cables at the same end, and at the end opposite to the same end, the cable corresponding to the cable to which the input electrical signal is received is determined by processing the output signals detected from the multiple cables respectively.

[0023] Cable arranging clamps, for example, include a slot forming portion having multiple slots for holding the cables. The slot forming portion includes a support member made of an insulator and multiple metal members spaced apart on the surface of the support member. The slot is formed by the support member and two adjacent metal members. Adjacent metal members are electrically insulated in the width direction of the slot.

[0024] Furthermore, the cable arranging clamp, for example, includes a slot forming portion having multiple slots for holding the cables. The slot forming portion includes multiple metal components having the slots formed therein. These metal components are arranged at intervals in the width direction of the slots. Adjacent metal components in the width direction of the slots are electrically insulated.

[0025] In the inspection method for multi-core cables, which is another aspect of this disclosure, a cable arrangement clamp, which is one or more aspects of this disclosure, is used. Therefore, according to the inspection method for multi-core cables, which is another aspect of this disclosure, it is possible to prevent the grooves of the cable arrangement clamp from becoming shallower due to wear. Furthermore, according to the inspection method for multi-core cables, which is another aspect of this disclosure, the detection voltage can be increased. Attached Figure Description

Detailed Implementation

[0047] The embodiments of this disclosure are illustrated with reference to the accompanying drawings.

[0048] <First Implementation>

[0049] 1. Structure of cable arrangement clamp 1

[0050] based on Figures 1-3 To illustrate the structure of cable arrangement clamp 1. For example... Figure 1 As shown, the cable arranging clamp 1 is a plate-shaped component. When viewed from the thickness direction, the cable arranging clamp 1 has an arc shape. The cable arranging clamp 1 has a groove forming part 3 on one side.

[0051] like Figure 2 , Figure 3 As shown, a plurality of grooves 5 are formed in the groove forming part 3. The length direction L of the groove 5 is radial in the arc shape of the cable arranging clamp 1. The groove 5 is formed from one end of the cable arranging clamp 1 to the opposite end. When viewed from the plate thickness direction of the cable arranging clamp 1, the shape of the groove 5 is a straight line.

[0052] The groove forming part 3 includes a support member 7 and a plurality of metal parts 9. The support member 7 is made of an insulating material. For example, resin can be used as an insulating material. The surface of the support member 7 is flat. The plurality of metal parts 9 are arranged at intervals on the surface of the support member 7.

[0053] The groove 5 is composed of a support member 7 and two adjacent metal members 9 in the width direction W. The width direction W is orthogonal to the length direction L of the groove 5. The two adjacent metal members 9 in the width direction W are electrically insulated. The portion of the surface of the groove forming part 3 that is adjacent to the groove 5 (hereinafter referred to as the adjacent part 3A) is composed of metal members 9.

[0054] Each slot 5 can hold the cable 11. The cable 11, for example, enters the interior of the slot 5 and contacts the bottom surface of the slot 5. Furthermore, the cable 11, for example, contacts the sides of the slot 5. The depth of the slot 5 is preferably more than half the diameter of the cable 11. When the depth of the slot 5 is more than half the diameter of the cable 11, the cable 11 is difficult to detach from the slot 5. The cable 11 is, for example, a cable comprising a multi-core cable. The cable 11, for example, has a conductor 11A and a sheath 11B. The sheath 11B covers the outer peripheral surface of the conductor 11A. Furthermore, the cable 11 can also be a coaxial cable.

[0055] The cable arrangement clamp 1 can be used with the electrode unit 13. The electrode unit 13 includes a support plate 15 and a plurality of electrodes 17. The electrode unit 13 is, for example, a printed circuit board. The material of the support plate 15 is, for example, FR4. The electrodes 17 are, for example, made of copper foil. The plurality of electrodes 17 are arranged at intervals on the lower surface of the support plate 15. Furthermore, the plurality of electrodes 17 are electrically insulated from each other. When the electrode unit 13 is positioned opposite the slot forming portion 3, each electrode 17 is opposite to a cable 11 held in the slot 5. The spacing between two adjacent electrodes 17 in the width direction W is preferably greater than the diameter of the cable 11. In this case, the stray capacitance 41 is further reduced, and the detection voltage is further increased.

[0056] Multiple electrode pads 18 are formed on the upper surface of the support plate 15. One electrode pad 18 corresponds to one electrode 17. The electrode pad 18 is electrically connected to the corresponding electrode 17 via a through-hole. One end of a coaxial line 20 is connected to the electrode pad 18. The other end of the coaxial line 20 is connected to the transmitting or receiving section of an external electrical device.

[0057] 2. Inspection methods for multi-core cables

[0058] based on Figures 1-4 This section explains the inspection methods for multi-core cables. Figure 4 The structure of the multi-core cable 19, which is the object of inspection, is shown. The multi-core cable 19 includes multiple cables 11. Furthermore, Figure 4Two cables 11 are shown, but the multi-core cable 19 may include three or more cables 11. The diameter of the cable 11 is, for example, 0.1 mm or more and 0.5 mm or less. The cable 11 is, for example, a coaxial cable. In the case of a coaxial cable, the cable 11 has an inner conductor 21, an insulation layer 23, an outer conductor 25, and a sheath 27. The cable 11 may also be an insulated wire having a conductor composed of single wires or stranded wires and an insulator covering the conductor. Multiple cables 11 may also be a combination of insulated wires and coaxial cables.

[0059] At one end of the multi-core cable 19 (hereinafter referred to as the first end 29), a cable arranging clamp 1 is used to arrange the plurality of cables 11 included in the multi-core cable 19. That is, as Figure 2 , Figure 3 As shown, a cable 11 is pressed into each groove 5. At this time, while pressing the cable 11 into the groove 5 using a pressing member (not shown), the pressing member is slid along the length L of the groove 5.

[0060] Next, as Figure 2 , Figure 3 As shown, electrode unit 13 is positioned opposite cable arrangement fixture 1. Each electrode 17 is positioned opposite a cable 11 held in slot 5.

[0061] Next, as Figure 4 As shown, an AC electrical signal is input from the opposing electrode 17 to one of the cables 11 held in the cable arrangement clamp 1. The electrical signal is generated by the signal source 31. Simultaneously, at the opposite ends of the multi-core cable 19 (hereinafter referred to as the second end 33), electrodes 35 are respectively brought into contact with the plurality of cables 11. Furthermore, processing is performed to detect the output signal from each of the plurality of cables 11. The cable 11 that detects the output signal corresponds to the cable 11 that received the electrical signal.

[0062] For example, an electrical signal with a phase opposite to that of the electrical signal from the signal source 31 can be input to a cable 11 adjacent to the cable 11 that receives the electrical signal from the signal source 31. In this case, by suppressing crosstalk, the output signal becomes difficult to detect on the cable 11 other than the cable 11 that receives the electrical signal from the signal source 31.

[0063] 3. The effect of cable arrangement clamp 1

[0064] (1A) In the cable arranging clamp 1, the adjacent part 3A is made of metal part 9. Therefore, the cable arranging clamp 1 can prevent the groove 5 from becoming shallow due to wear.

[0065] (1B) In the cable arrangement clamp 1, two adjacent metal parts 9 in the width direction W are electrically insulated. Therefore, no stray capacitance is generated between the electrode 17 and the adjacent electrode 17 through the metal parts 9. As a result, the cable arrangement clamp 1 can increase the detection voltage.

[0066] based on Figures 5-8 To further illustrate this effect. Figure 5 This model represents the electrical structure corresponding to the case where cable arrangement fixture 1 is used. In this model, the number of cables 11 is set to three. A signal source 31 is connected to one end of the cable 11 whose correspondence is to be investigated, and a receiving unit 60 is connected to the other end. Furthermore, an auxiliary signal source 61 is connected to one end of the cable 11 adjacent to the cable 11 whose correspondence is to be investigated. The auxiliary signal source 61 outputs an electrical signal with a phase opposite to the electrical signal from the signal source 31. By inputting an electrical signal with a phase opposite to the adjacent cable 11, crosstalk with the cable 11 whose correspondence is to be investigated can be suppressed, thereby enabling high-precision investigation of the correspondence between the ends of the cables 11. In this model, there is a coupling capacitance 37 between the cables 11 and a coupling capacitance 39 between the electrode 17 and the cable 11. There is no stray capacitance between the electrodes 17.

[0067] As a comparison object, assume Figure 6 , Figure 7 The cable arranging clamp 201 is shown. In the cable arranging clamp 201, a continuous metal part 9 in the width direction W has a plurality of slots 5. Figure 8 This model represents the electrical structure corresponding to the case where the cable arrangement clamp 201 is used. In this model, the number of cables 11 is set to three. A signal source 31 is connected to one end of the cable 11 for which the correspondence is to be investigated, and a receiver 60 is connected to the other end. Furthermore, an auxiliary signal source 61 is connected to one end of the cable 11 adjacent to the cable 11 for which the correspondence is to be investigated. The auxiliary signal source 61 outputs an electrical signal with a phase opposite to the electrical signal from the signal source 31. In this model, there are coupling capacitances 37 between cables 11, coupling capacitances 39 between electrodes 17 and cables 11, and stray capacitances 41 between electrodes 17.

[0068] In simulation Figure 5 The detection voltage in the model shown is 7.31 μV. Under the same conditions, in the simulation... Figure 8 The detection voltage in the model shown is 4.87 μV. This simulation result confirms that the cable arrangement clamp 1 increases the detection voltage.

[0069] (1C) In the cable arrangement fixture 1, the width of the metal parts 9 can be increased. Therefore, for example, multiple metal parts 9 can be easily formed by etching copper foil.

[0070] <Second Implementation>

[0071] 1. Differences from the first embodiment

[0072] The basic structure of the second embodiment is the same as that of the first embodiment, therefore the differences will be described below. Furthermore, the same symbols as in the first embodiment indicate the same structure, referring to the above description.

[0073] In the first embodiment described above, the groove 5 is composed of a support member 7 and two adjacent metal members 9. In contrast, in the second embodiment, as... Figure 9 , Figure 10 As shown, a groove 5 is formed in a metal component 9, which differs from the first embodiment. Both sides and the bottom of the groove 5 are formed of the metal component 9. The depth of the groove 5 is greater than half the diameter of the cable 11 and less than the diameter of the cable 11.

[0074] Two adjacent metal parts 9 are separated in the width direction W. Therefore, two adjacent metal parts 9 are electrically insulated in the width direction W. Between two adjacent slots 5, there is a portion without metal parts 9 (hereinafter referred to as the non-metal part portion 43). The adjacent portion 3A is composed of metal parts 9. In addition, an insulating member such as rubber or resin with the same thickness as the metal parts 9 can be provided on the non-metal part portion 43. By providing this insulating member, it is possible to prevent the cable 11 from being pressed into the non-metal part portion 43, and the cable 11 can be easily pressed into the slot 5.

[0075] 2. The effect of cable arrangement clamp 1

[0076] According to the second embodiment detailed above, the effects of the first embodiment described above (1A) and (1B) are achieved, and the following effects are achieved.

[0077] (2A) The cable arrangement clamp 1 has a section 43 without metal parts. Therefore, the stray capacitance 41 between the electrodes 17 is further reduced. As a result, the cable arrangement clamp 1 can further increase the detection voltage.

[0078] <Third Implementation Method>

[0079] 1. Differences from the first embodiment

[0080] The basic structure of the third embodiment is the same as that of the first embodiment, therefore the differences will be described below. Furthermore, the same symbols as in the first embodiment indicate the same structure, referring to the above description.

[0081] In the first embodiment described above, the metal component 9 forms part of the groove 5 at both ends in the width direction W. In contrast, in the third embodiment, as... Figure 11 As shown, only one end of the metal component 9 in the width direction W forms part of the groove 5, which differs from the first embodiment. The bottom surface of the groove 5 is formed by the support component 7.

[0082] 2. The effect of cable arrangement clamp 1

[0083] According to the third embodiment described above, the effects of the first embodiment described above are achieved, and the following effects are also achieved.

[0084] (3A) In this embodiment, the bottom surface of the groove 5 may not be formed by the metal component 9, thereby reducing the thickness of the metal component 9. Furthermore, compared to the first embodiment, the metal component 9 can be made smaller. Therefore, the manufacturing cost of the cable arrangement clamp 1 can be reduced.

[0085] <Fourth Implementation>

[0086] 1. Differences from the second embodiment

[0087] The basic structure of the fourth embodiment is the same as that of the second embodiment, therefore the differences will be described below. Furthermore, the same symbols as in the second embodiment indicate the same structure, referring to the above description.

[0088] In the second embodiment described above, the depth of the groove 5 is less than or equal to the diameter of the cable 11. In contrast, in the fourth embodiment, as... Figure 12 As shown, the depth of the groove 5 is greater than the diameter of the cable 11, which differs from the second embodiment. When the electrode unit 13 is positioned opposite the groove forming portion 3, the electrode 17 abuts against the metal component 9. The cross-sectional shape of the corner 45 of the side and bottom surfaces of the groove 5 is a shape formed by two intersecting planes.

[0089] 2. The effect of cable arrangement clamp 1

[0090] According to the fourth embodiment described above, the effects of the second embodiment described above are achieved, and the following effects are also achieved.

[0091] (4A) Since electrode 17 is in contact with metal component 9, the electrical signal enters cable 11 through electrode 17 and metal component 9. As a result, the coupling capacitance 39 between electrode 17 and cable 11 further increases, and the detection voltage further increases.

[0092] <Fifth Implementation>

[0093] The basic structure of the fifth embodiment is the same as that of the fourth embodiment, therefore the differences will be described below. Furthermore, the same symbols as in the fourth embodiment indicate the same structure, referring to the above description.

[0094] In the fourth embodiment described above, the cross-sectional shape of the corner 45 of the side and bottom surfaces of the groove 5 is a shape formed by two intersecting planes. In contrast, in the fifth embodiment, as... Figure 13As shown, the cross-sectional shape of corner 45 is a shape that protrudes toward cable 11. A shape that protrudes toward cable 11 means that, compared to a shape consisting of two intersecting planes as in the fourth embodiment, the distance between corner 45 and cable 11 is smaller. The cross-sectional shape of corner 45 can be a stepped shape or a curved surface shape.

[0095] 2. The effect of cable arrangement clamp 1

[0096] According to the fifth embodiment described above, the effects of the fourth embodiment described above are achieved, and the following effects are achieved.

[0097] (5A) In this embodiment, since the cross-sectional shape of the corner 45 protrudes towards the cable 11, the contact area between the metal component 9 and the cable 11 is further increased. Therefore, the electrical signal can more easily enter the cable 11 via the electrode 17 and the metal component 9. As a result, the coupling capacitance 39 between the electrode 17 and the cable 11 is further increased, and the detection voltage is further increased.

[0098] <Sixth Implementation Method>

[0099] The basic structure of the sixth embodiment is the same as that of the second embodiment, therefore the differences will be described below. Furthermore, the same symbols as in the second embodiment indicate the same structure, referring to the above description.

[0100] In the second embodiment described above, a plurality of metal parts 9 are arranged on the flat surface of the support member 7. In contrast, in the sixth embodiment, as... Figure 14 As shown, a metal component 9 is installed in the recess 47 formed in the support component 7. The metal component 9 has a plate-like shape that covers the surface of the recess 47 and its surroundings. A groove 5 is formed in the metal component 9. The side and bottom surfaces of the groove 5 are formed by the metal component 9. The adjacent portion 3A is also formed by a plate-like metal component 9 that covers the surface of the support component 7. Two adjacent metal components 9 in the width direction W are electrically insulated.

[0101] 2. The effect of cable arrangement clamp 1

[0102] The sixth embodiment described above achieves the same effect as the second embodiment described above.

[0103] <Seventh Implementation>

[0104] The basic structure of the seventh embodiment is the same as that of the third embodiment, therefore the differences will be described below. Furthermore, the same symbols as in the third embodiment indicate the same structure, referring to the above description.

[0105] In the third embodiment described above, the groove 5 is composed of a flat support member 7 and two adjacent metal members 9. In contrast, in the seventh embodiment, as... Figure 15 As shown, the groove 5 is composed of a recess 47 formed in the support member 7 and two metal members 9 disposed on both sides of the recess 47. The two metal members 9 are adjacent in the width direction W and electrically insulated from each other.

[0106] 2. The effect of cable arrangement clamp 1

[0107] According to the seventh embodiment detailed above, the effects of the third embodiment described above are achieved.

[0108] <Eighth Implementation Method>

[0109] The basic structure of the eighth embodiment is the same as that of the second embodiment, therefore the differences will be described below. Furthermore, the same symbols as in the second embodiment indicate the same structure, referring to the above description.

[0110] In the second embodiment described above, the structure of the groove forming portion 3 is the same along the entire length direction L. In contrast, in the eighth embodiment, as... Figure 16 As shown, the groove forming portion 3 is divided into a first portion 49, a second portion 51, and a third portion 53 along the length direction L. The first portion 49 has the same structure as the groove forming portion 3 in the second embodiment. The second portion 51 and the third portion 53 are formed, for example, from a metallic material.

[0111] The second part 51 has multiple slots 55. The slots 55 are located on the extension lines of slot 5. The shape of the slots 55 is the same as that of slot 5. The slots 55 are capable of holding the cable 11.

[0112] like Figure 17 As shown, the portion 57 of the second part 51 between two adjacent slots 55 does not have a recess for the cable 11 to fall into. The third part 53 also has the same structure as the second part 51.

[0113] The groove forming part 3 may also consist of only one of the second part 51 and the third part 53. The first part 49 and the second part 51 may be integrated or separate. The first part 49 and the third part 53 may be integrated or separate. The first part 49, the second part 51, and the third part 53 may be integrated or separate.

[0114] 2. The effect of cable arrangement clamp 1

[0115] According to the eighth embodiment detailed above, the effects of the second embodiment described above are achieved, and the following effects are also achieved.

[0116] (8A) In the second part 51 and the third part 53, the only part that can hold the cable 11 is the groove 55. If the cable 11 is held in the groove 55, the cable 11 will inevitably enter the groove 5. Therefore, it is possible to prevent the cable 11 from entering between two adjacent metal parts 9.

[0117] <Other Implementation Methods>

[0118] The above describes the embodiments of this disclosure, but this disclosure is not limited to the above embodiments and can be implemented in various modifications.
