DETAILED DESCRIPTION

[0029] The multi-core communication cable continuity detection device 100 and the continuity detection method thereof according to the present application are described in further detail below in conjunction with the drawings and the specific embodiments.

[0030] The following describes a multi-core communication cable continuity detection device 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0031] like Figure 1 As shown, the multi-core communication cable continuity detection device 100 according to an embodiment of the present invention may include a power control device 1 and a cable connection terminal 2.

[0032] Specifically, if Figure 2 As shown, the power control device 1 includes a power supply 11, an alarm device 12 and a power test terminal 13. The power test terminal 13 is provided with a plurality of power contacts 14, wherein the power supply 11 has a positive pole and a negative pole. The positive pole and the negative pole of the power supply 11 are both connected to the power test terminal 13 and the positive pole and the negative pole are not connected to each other. The plurality of power contacts 14 are independent of each other and are not connected.

[0033] One of the power contacts 14 is connected to the positive or negative pole of the power supply 11, and the other power contacts 14 are connected to the other of the positive and negative poles of the power supply 11. Specifically, in some examples of the present invention, one of the multiple power contacts 14 is connected to the positive pole of the power supply 11, and all other power contacts 14 are connected and conductive to the negative pole of the power supply 11; in other examples of the present invention, one of the multiple power contacts 14 is connected and conductive to the negative pole of the power supply 11, and all other power contacts 14 are connected and conductive to the positive pole of the power supply 11.

[0034] The alarm device 12 is connected between the power supply 11 and the power test terminal 13 to sound an alarm when the positive and negative poles of the power supply 11 are connected, wherein the alarm device 12 can be arranged between the positive pole of the power supply 11 and the power test terminal 13, or the alarm device 12 can be arranged between the negative pole of the power supply 11 and the power test terminal 13, so that when the multi-core communication cable is tested, the alarm issued by the alarm device 12 can reflect the on-off detection information of the multi-core communication cable. For example, when the tested cable 3 is subjected to mixed line detection, if there is a mixed line in the tested cable 3, the positive and negative poles of the power supply 11 are connected through the tested cable 3 to form a closed circuit, thereby the power supply 11 supplies power to the alarm device 12 so that the alarm device 12 sounds an alarm. When the tested cable 3 is subjected to broken line detection, if there is no broken line in the tested cable 3, the alarm device 12 sounds an alarm, and if there is a broken line in the tested cable 3, the alarm device 12 does not sound an alarm.

[0035] The cable connecting end 2 is adapted to be connected with the measured cable 3, at least one of the power supply control device 1 and the cable connecting end 2 is rotatable, that is, the power supply control device 1 and the cable connecting end 2 can relatively rotate, for example, the power supply control device 1 is fixed, the cable connecting end 2 rotates, or the cable connecting end 2 is fixed, the power supply control device 1 rotates, or both the power supply control device 1 and the cable connecting end 2 can rotate, wherein the rotation direction or rotation speed of the power supply control device 1 and the cable connecting end 2 can be set as required, so that the power supply control device 1 and the cable connecting end 2 can relatively rotate.

[0036] The cable connecting end 2 is provided with a plurality of cable contacts 21, wherein the plurality of cable contacts 21 are independent of each other and not conductive, the measured cable 3 is a multi-core cable, that is, the measured cable 3 has a plurality of wire cores 31, and the cable connecting end 2 is provided with a plurality of cable contacts 21, so that when the measured cable 3 is detected, the plurality of wire cores 31 can be connected with the plurality of cable contacts 21 respectively to realize the detection of each wire core 31. As for the number of cable contacts 21, the cable contacts 21 can be set according to actual needs, which is not specially limited in the present application.

[0037] The plurality of cable contacts 21 correspond to the plurality of power supply contacts 14 one by one. That is, the plurality of cable contacts 21 correspond to the positions of the plurality of power supply contacts 14 one by one, so that the plurality of cable contacts 21 and the plurality of power supply contacts 14 can be correspondingly contacted and connected, the cable contact 21 is connected with the wire core 31 of the measured cable 3, so that the plurality of power supply contacts 14 are connected with the plurality of wire cores 31 through the cable contact 21 to realize the connection and conduction of the positive and negative poles of the power supply 11. In this way, whether the positive and negative poles of the power supply 11 are conductive can realize the detection of the broken wire and mixed wire of the measured cable 3.

[0038] Specifically, when the measured cable 3 is detected, one of the power supply contacts 14 is connected with the positive or negative pole of the power supply 11, and all the other power supply contacts 14 are connected with the other of the positive or negative pole, that is, the positive or negative pole of the power supply 11 is connected and conducted with one wire core 31 of the measured cable 3 through the power supply contact 14 and the cable contact 21, and the other of the positive or negative pole is connected and conducted with all the other wire cores 31 of the measured cable 3, so that the one wire core 31 connected with the positive or negative pole can be matched with all the other wire cores 31 connected with the other of the positive or negative pole, and whether the wire core 31 is conductive with all the other wire cores 31 can be judged by whether the positive and negative poles are conductive, and then whether the wire core 31 is broken or mixed with other wire cores 31 can be judged.

[0039] The power supply control device 1 and the cable connection end 2 are rotated one circle, so that each wire core 31 can be paired with all other wire cores 31 for detection, thereby achieving detection of each wire core 31 without manual matching of the wire cores 31, avoiding missed detection, reducing detection time and improving detection efficiency.

[0040] Further, in combination with Figures 3-5 As shown in the figure, when the mixed wire detection of the measured cable 3 is performed, the multiple wire cores 31 at one end of the measured cable 3 are scattered and connected to the multiple cable contacts 21 one by one, and the multiple wire cores 31 at the other end of the measured cable 3 are scattered and guaranteed not to conduct to each other, as shown in the figure. Figure 4 As shown in the figure, if the measured cable 3 does not have mixed wires, the wire cores 31 are independent of each other and do not conduct, so that the positive and negative poles of the power supply 11 do not conduct, as shown in the figure. Figure 5 As shown in the figure, if the measured cable 3 has mixed wires, one of the mixed wire cores 31 is connected to the positive or negative pole, and the other one or more of the mixed wire cores 31 is connected to the other of the positive or negative pole, so that the positive and negative poles of the power supply are connected through the mixed wires, thereby enabling the alarm device 12 to issue an alarm, and the mixed wire condition of the measured cable 3 can be determined.

[0041] In combination with Figures 6-8 As shown in the figure, when the broken wire detection of the measured cable 3 is performed, the multiple wire cores 31 at one end of the measured cable 3 are scattered and connected to the multiple cable contacts 21 one by one, and the multiple wire cores 31 at the other end of the measured cable 3 are connected to each other. As shown in the figure, Figure 7 As shown in the figure, if the measured cable 3 does not have broken wires, the wire cores 31 conduct to each other, so that the positive and negative poles of the power supply are connected through the measured cable 3, thereby enabling the alarm device 12 to issue an alarm, as shown in the figure. Figure 8 As shown in the figure, if the measured cable 3 has broken wires, the broken wire cores 31 are independent of and not connected to all other wire cores 31, so that when the broken wire core 31 is connected to one of the positive or negative poles and all other wire cores 31 are connected to the other of the positive or negative pole, the positive and negative poles of the power supply 11 do not conduct, and the alarm device 12 does not issue an alarm, thereby determining that the measured cable 3 has broken wires.

[0042] Therefore, the multi-core communication cable continuity detection device 100 according to the embodiment of the application can perform continuity detection on the multi-core communication cable, is simple to operate and can realize automatic detection, does not need manual matching of the multiple wire cores 31 of the multi-core cable for test, can avoid missed detection, saves time and effort, and can improve detection efficiency and detection quality and reduce labor cost.

[0043] In some examples of the application, in combination with Figures 3-5As shown, one of the power supply contacts 14 is connected to the positive pole of the power supply 11, and the other power supply contacts 14 are connected to the negative pole of the power supply 11. The power supply contact 14 connected to the positive pole of the power supply 11 can be a positive contact, and the other power supply contacts 14 can be negative contacts.

[0044] In this way, when the mixed-wire detection of the measured cable 3 is performed, one end of the measured cable 3 is connected to the power supply test end 13 through the cable connection end 2, and the other end of the measured cable 3 is scattered and not conductive. If the wire core 31 connected to the positive contact is one of the mixed-wire wire cores, the other mixed-wire wire core is connected to the negative contact and is conductive, so that the positive contact and the negative contact are conductive through the mixed-wire of the measured cable 3, and the positive pole and the negative pole of the power supply 11 form a closed loop, and the alarm device 12 issues an alarm. If the wire core 31 connected to the positive contact is an independent wire core, the positive contact and the negative contact cannot be conductive, and the alarm device 12 does not issue an alarm. The relative rotation of the power supply control device 1 and the cable connection end 2 enables the positive contact to be in contact with each wire core 31 and to be conductive, so that the detection of each wire core 31 in the measured cable 3 can be realized to determine whether the mixed-wire situation occurs in the measured cable 3, and the specific wire core 31 and the number of mixed-wire wire cores in the measured cable 3 can also be determined.

[0045] In combination Figures 6-8 As shown, when the broken-wire detection of the measured cable 3 is performed, one end of the measured cable 3 is connected to the power supply test end 13 through the cable connection end 2, and the other end of the measured cable 3 is connected and conductive. If the wire core 31 connected to the positive contact is not broken, since the other end of the plurality of wire cores 31 is connected and conductive, since all the other wire cores 31 are connected to the negative contact, the positive contact is conductive through at least one of the negative contact and the measured cable 3, and the alarm device 12 issues an alarm; if the wire core 31 connected to the positive contact is broken, the positive contact and the negative contact cannot be conductive, and the alarm device 12 does not issue an alarm. In this way, the relative rotation of the power supply control device 1 and the cable control device enables the positive contact to be in contact with each wire core 31 and to be conductive, so that the detection of each wire core 31 in the measured cable 3 can be realized to determine whether the broken-wire situation occurs in the measured cable 3, and the specific wire core 31 and the number of broken-wire wire cores in the measured cable 3 can also be determined.

[0046] In some embodiments of the present invention, the cable connection end 2 is fixed, and the power control device 1 is rotatable relative to the cable connection end 2. The power control device 1 rotates to bring the multiple power contacts 14 into contact and conduction with the multiple cable contacts 21. This not only achieves a one-to-one connection between the multiple power contacts 14 and the multiple cable contacts 21, but also prevents the cable connection end 2 from being connected to the cable under test 3 and being fixed, thereby preventing the cable under test 3 from rotating with the cable connection end 2. This makes the multi-core communication cable continuity detection device 100 more stable and prevents the rotation of the cable connection end 2 from causing the cable under test 3 to rotate, thereby affecting the detection results.

[0047] Optionally, the multi-core communication cable continuity detection device 100 according to an embodiment of the present invention further includes: a balancing shaft 4, on which the power control device 1 and the cable connection end 2 are both sleeved and arranged relative to each other along the axial direction of the balancing shaft 4. Thus, the balancing shaft 4 enables the power control device 1 and the cable connection end 2 to maintain balance, so that the power contacts 14 and the cable contacts 21 can be in one-to-one contact, thereby avoiding the power control device 1 and the cable connection end 2 from being offset, which may cause the power contacts 14 and the cable contacts 21 to be unable to connect to each other.

[0048] In some embodiments of the present invention, multiple power contacts 14 are arranged on the side of the power test end 13 and the multiple power contacts 14 are spaced apart along the circumference of the power test end 13. In this way, when the power control device 1 and the cable connection end 2 rotate relative to each other, the multiple power contacts 14 rotate circumferentially relative to the cable connection end 2. Therefore, when the power control device 1 rotates once relative to the cable connection end 2, the multiple power contacts 14 can rotate one grid relative to each other, so that the contact and connection positions of the multiple power contacts 14 and the multiple cable contacts 21 change once in the circumferential direction. In this way, when the cable connection end 2 and the power control device 1 rotate relative to each other for one circle, each power contact 14 can contact the multiple cable contacts 21 once, so as to realize the detection of multiple cores 31 of the cable 3 under test.

[0049] like Figure 1 As shown, multiple cable contacts 21 are arranged on the side of the cable control end facing the power supply control device 1, and are arranged one-to-one with the multiple power contacts 14, wherein the multiple cable contacts 21 can be arranged at intervals along the circumference of the cable connection end 2, and the multiple cable contacts 21 are arranged on the side of the cable connection end 2, corresponding one-to-one with the multiple power contacts 14 on the side of the power supply test end 13, so that the power supply control device 1 and the cable connection end 2 rotate relative to each other, so that the multiple cable contacts 21 and the multiple power contacts 14 can be in contact and conductive.

[0050] Optionally, the other side of the cable connection end 2 is provided with a connection point suitable for connecting to the cable under test 3, and there are multiple connection points, each of which is connected one by one to the multiple cable contacts 21. In this way, the connection point facilitates the connection and conduction between the core 31 of the cable under test 3 and the cable contact 21. Furthermore, a claw or other clamping device can be provided at the connection point to facilitate the connection between the core 31 of the cable under test 3 and the connection point.

[0051] In some embodiments of the present invention, multiple power contacts 14 are evenly spaced along a circle or a regular polygon, so that the circumferential distances of the multiple power contacts 14 on the power test end 13 are the same, so that the power control device 1 and the cable connection end 2 can still correspond one-to-one with the multiple cable contacts 21 after relative rotation.

[0052] Optionally, the alarm device 12 may be an indicator light 122 and / or a buzzer 121, that is, the alarm device 12 may be an indicator light 122, or the alarm device 12 may be a buzzer 121, or the alarm device 12 may include both the indicator light 122 and the buzzer 121, such as Figure 1 As shown, the alarm device 12 includes an indicator light 122 and a buzzer 121, wherein the indicator light 122 can be arranged between the negative pole of the power supply 11 and the power contact 14, and the buzzer 121 can be arranged between the positive pole of the power supply 11 and the power contact 14. In this way, when the positive pole and the negative pole of the power supply 11 are connected, the buzzer 121 can emit a buzzer alarm and the indicator light 122 can emit light. The detection information of the tested cable 3 can be judged according to the buzzer 121 and the indicator light 122.

[0053] The following describes a multi-core communication cable continuity detection method according to an embodiment of the present invention with reference to the accompanying drawings. The multi-core communication cable continuity detection method according to an embodiment of the present invention can be implemented using the multi-core communication cable continuity detection device 100 of the above embodiment.

[0054] like Figure 9 As shown, the on / off detection method of a multi-core communication cable according to an embodiment of the present invention may include:

[0055] S1: Multiple cores 31 of the tested cable 3 are connected one-to-one with multiple cable contacts 21 of the cable connection end 2, wherein the tested cable 3 is a multi-core cable having multiple cores 31. The multiple cores 31 at one end of the tested cable 3 are spread out and connected one-to-one with the multiple cable contacts 21 respectively;

[0056] S2: The power control device 1 is brought into contact with the cable contacts 21 in a one-to-one correspondence, and the alarm device 12 is used to detect whether the cable 3 under test is disconnected or mixed. Specifically, the power control device 1 has multiple power contacts 14, and the positions of the power control device 1 and the cable connection terminal 2 are adjusted so that the multiple power contacts 14 and the cable contacts 21 can be brought into contact in a one-to-one correspondence. The power control device 1 includes a power supply 11, and one of the multiple power contacts 14 is connected to the positive or negative pole of the power supply 11, while the other power contacts 14 are connected to the other of the positive and negative poles.

[0057] For example, one of the multiple power contacts 14 is connected to the positive pole of the power supply 11, and the other power contacts 14 are all connected to the negative pole of the power supply 11. The power contacts 14 and the cable contacts 21 are in contact and connected one by one, so that one core 31 of the tested cable 3 is connected to the positive pole of the power supply 11, and the other cores 31 are all connected to the negative pole of the power supply 11. Therefore, the on-off state of the core 31 connected to the positive pole of the power supply 11 and whether it is mixed with other cores 31 can be determined by the conductivity of the positive and negative poles of the power supply 11.

[0058] Alternatively, one of the multiple power contacts 14 is connected to the negative pole of the power supply 11, and the other power contacts 14 are all connected to the negative and positive poles of the power supply 11. The power contacts 14 are in contact and connected with the cable contacts 21 in a one-to-one correspondence, so that one core 31 of the tested cable 3 is connected to the negative pole of the power supply 11, and the other cores 31 are all connected to the positive pole of the power supply 11. Therefore, the on-off state of the core 31 connected to the negative pole of the power supply 11 and whether it is mixed with other cores 31 can be determined by the conductivity of the positive and negative poles of the power supply 11.

[0059] like Figures 6-8 As shown, when detecting whether a multi-core cable is broken, one end of each of the multiple cores 31 of the tested cable 3 is connected to each of the multiple cable contacts 21, and the other ends of the multiple cores 31 of the tested cable 3 are connected to each other. In this way, the positive pole of the power supply 11 is connected to one core 31 through the power contact 14 and the cable contact 21, and the other cores 31 are connected to the negative pole of the power supply 11 through the power contact 14 and the cable contact 21. Since the other ends of the multiple cores 31 are connected to each other, the core 31 connected to the positive pole is also connected to the negative pole of the power supply 11. Therefore, when the core 31 connected to the positive pole of the power supply 11 is broken, the positive and negative poles of the power supply 11 cannot be connected, and the alarm device 12 will not sound an alarm. When the core 31 connected to the positive pole of the power supply 11 is not broken, the positive and negative poles of the power supply 11 are connected, and the alarm device 12 sounds an alarm.

[0060] like Figures 3-5As shown, when detecting whether the multi-core cable is mixed, one end of the plurality of cores 31 of the measured cable 3 is connected to the plurality of cable contacts 21 one by one, and the other end of the plurality of cores 31 of the measured cable 3 is scattered and not connected to each other. In this way, the positive electrode of the power supply 11 is connected to one core 31 through the power supply contact 14 and the cable contact 21, and the other cores 31 are connected to the negative electrode of the power supply 11 through the power supply contact 14 and the cable contact 21. Since the other end of the plurality of cores 31 is scattered and not connected to each other, the core 31 connected to the positive electrode is not connected to the negative electrode of the power supply 11, and the core 31 connected to the negative electrode is not connected to the positive electrode. Therefore, when the core 31 connected to the positive electrode of the power supply 11 is not mixed with the other cores 31, the positive electrode and the negative electrode of the power supply 11 cannot be connected, and the alarm device 12 does not alarm. When the core 31 connected to the positive electrode of the power supply 11 is mixed with the other cores 31, the positive electrode and the negative electrode of the power supply 11 are connected, and the alarm device 12 alarms.

[0061] S3: rotate the power supply control device 1 and / or the cable connection end 2 so that each power supply contact 14 is connected to the plurality of cable contacts 21 one by one; that is, at least one of the power supply control device 1 and the cable connection end 2 is rotatable, so that the power supply control end and the cable connection end 2 can rotate relative to each other, and each power supply contact 14 can be connected to the plurality of cable contacts 21 one by one. Thus, the detection of whether each core 31 is disconnected and mixed with other cores 31 can be realized, and not only the multi-core cable can be detected for mixed and disconnected cores 31, but also the specific mixed and disconnected cores 31 of the multi-core cable can be detected.

[0062] Thus, according to the multi-core communication cable detection method of the embodiment of the present application, the mixed or disconnected detection of the multi-core communication cable can be realized, manual pairing and arrangement of the cores 31 can be avoided, and the detection efficiency and quality can be improved, and the labor cost can be reduced.

[0063] The above is only a preferred embodiment of the present application, and it should be pointed out that those skilled in the art can make some improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
