Description

Technical Field

[0001] This utility model belongs to the field of cable testing technology, and in particular relates to a cable continuity testing device. Background Technology

[0002] When crimping terminals onto cables, the insulation at the cable end needs to be removed, followed by the shielding mesh, which can then be removed or folded back to remove the insulation at the core wire end. Finally, the terminal is crimped onto the core wire end. To prevent continuity issues between the cable core wire and the shielding mesh, or between the shielding mesh and the insulation, it is necessary to perform continuity testing on the cable.

[0003] To achieve cable continuity detection, Chinese invention patent document CN119438642A discloses a cable continuity detection device and method, comprising: a cable clamping assembly, the cable clamping assembly including clamping claws for clamping the cable sheath; and a detection assembly, disposed opposite to the clamping center of the cable clamping assembly, the detection assembly including two first detection clamps, a second detection clamp, and a third detection clamp. The first detection clamp is a column for clamping the shielding layer, and the second and third detection clamps are sheet-like, with a semi-circular groove at the end of the second and third detection clamps facing the cable. The two sets of semi-circular grooves are respectively used to clamp the cable insulation layer and the central conductor; wherein, the circle formed by the merging of the two semi-circular grooves of the second detection clamp is adapted to the outer diameter of the insulation layer, and the two second detection clamps are conductors, and are electrically conductive when the insulation layer is clamped in place; the first, second, and third detection clamps are also used for pairwise continuity detection. Move the cable to the clamping center of the detection component and clamp the outer sheath of the cable to be tested through the clamping component; close the detection component so that the first detection clamp clamps the cable shielding layer, the second detection clamp clamps the insulation layer, and the third detection clamp clamps the center conductor; energize the second detection clamp and determine whether there is continuity between the two second detection clamps. If there is no continuity, an alarm for incomplete clamping is issued; if there is continuity, the detection continues; energize and test each pair of the first, second, and third detection clamps. If a short circuit occurs between any two pairs, an alarm for shielding mesh overlap is issued.

[0004] The technical solution in the aforementioned patent literature involves single-end testing of the cable. To complete testing at both ends, the cable needs to be reversed, resulting in low testing efficiency. Furthermore, single-end testing cannot detect whether the core wire is conductive or whether the core wire is connected to the shielding mesh. Utility Model Content

A plurality of first clamping conductive members and second clamping conductive members are respectively provided on the opposite sides of the first clamping member and the second clamping member. The first clamping conductive member is electrically connected to the electrical conductivity detection device, and the second clamping conductive members of the two clamping conductive mechanisms are electrically connected to each other. The second clamping assembly includes a third clamping member and a fourth clamping member disposed opposite to each other. The third clamping member and the fourth clamping member are respectively provided with a plurality of third clamping conductive members and fourth clamping conductive members on their opposite sides. The third clamping conductive members are electrically connected to the electrical conductivity detection device, and the fourth clamping conductive members of the two clamping conductive mechanisms are electrically connected to each other. The moving drive mechanism drives the wire clamp and / or the clamping conduction mechanism to move.

[0007] Furthermore, the moving drive mechanism includes two lifting cylinders disposed on the upper end of the carrier plate, and the lifting cylinders are connected to the corresponding clamping and guiding mechanism.

[0008] Furthermore, the clamping and guiding mechanism also includes a lifting plate, which is slidably connected to the carrier plate, and the lifting cylinder is connected to the lifting plate. The first clamping assembly and the second clamping assembly are disposed on the lifting plate.

[0015] The cable continuity detection device provided in this embodiment of the present invention has at least the following technical effects: This cable continuity detection device clamps both ends of the cable to be tested onto two clamps, with the cable ends facing the detection device. A moving drive mechanism can switch the cable end between a first clamping assembly and a second clamping assembly. The cable end can be clamped by the first and second clamping assemblies, or by a third and fourth clamping assembly, so that the corresponding first and second clamping conductive elements respectively clamp the conductor of the core wire, the shielding mesh, and the insulation layer.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0024] In one embodiment of the cable continuity detection device of this utility model, please refer to... Figures 1 to 3The cable continuity detection device in this embodiment is used for cable continuity detection, such as whether the two ends of the core wire are conductive, whether the two ends of the shielding mesh are conductive, whether the insulation is conductive to the shielding mesh, and whether the core wire is conductive to the shielding mesh.

[0025] Specifically, please refer to Figures 1 to 3 This embodiment of the cable continuity detection device includes a base 100, wire clamps 200, a carrier plate 300, a detection device, and a moving drive mechanism. The base 100 has a mounting position 101 at its front end and a support surface 102 on its top side. Two wire clamps 200 are located at the mounting position 101, and can clamp both ends of the same cable. The carrier plate 300 is located on the support surface 102, and the detection device is located on the carrier plate 300. The detection device includes two sets of clamping and conducting mechanisms 400 arranged opposite to each other on one side of the carrier plate. Each clamping and conducting mechanism 400 includes a first clamping component 410 and a second clamping component 420 arranged opposite to each other. The first clamping component 410 and the second clamping component 420 can freely switch between clamping the ends of the cable on the wire clamps 200.

[0026] The first clamping assembly 410 includes a first clamping member 411 and a second clamping member 412 arranged opposite to each other. A plurality of first clamping conductive members 413 and second clamping conductive members 414 are respectively provided on opposite sides of the first clamping member 411 and the second clamping member 412. Each pair of opposite first clamping conductive members 413 and second clamping conductive members 414 forms a clamping position. The first clamping conductive members 413 are electrically connected to an electrical conductivity detection device (not shown in the attached figure), and the two pairs of second clamping conductive members 414 in the two clamping conductive mechanisms 400 are electrically connected to each other. Specifically, if there are three pairs of first clamping conductive members 413 and three pairs of second clamping conductive members 414, three sets of clamping positions are formed. One set of clamping positions is used to clamp the core conductor, another set is used to clamp the shielding mesh, and the remaining set is used to clamp the insulation layer. Therefore, when the first clamping member 411 and the second clamping member 412 clamp each other, the three sets of clamping positions formed by the three sets of first clamping conductive members 413 and second clamping conductive members 414 respectively clamp the core conductor, the shielding mesh and the insulating layer.

[0027] The second clamping assembly 420 includes a third clamping member 421 and a fourth clamping member 422 disposed opposite to each other. A plurality of third clamping conductive members 423 and fourth clamping conductive members 424 are respectively provided on opposite sides of the third clamping member 421 and the fourth clamping member 422. The third clamping conductive members 423 are electrically connected to an electrical conductivity detection device, and the fourth clamping conductive members 424 of the two second clamping assemblies 420 are electrically connected to each other. Specifically, there are three sets of both the third clamping conductive members 423 and the fourth clamping conductive members 424, forming three sets of clamping positions. One set of clamping positions is used to clamp the core conductor, another set is used to clamp the shielding mesh, and the remaining set is used to clamp the insulation layer. Therefore, when the third clamping member 421 and the fourth clamping member 422 clamp each other, the three sets of clamping positions formed by the three sets of third clamping conductors 423 and fourth clamping conductors 424 respectively clamp the core conductor, the shielding mesh and the insulating layer.

[0028] The moving drive mechanism drives the cable clamp 200 and / or the clamping conduction mechanism 400 to move. This allows the moving drive mechanism to switch the cable end clamped on the cable clamp 200 between the first clamping assembly 410 and the second clamping assembly 420.

[0029] In this embodiment, the cable continuity detection device clamps both ends of the cable to be tested onto two clamps 200, with the cable ends facing the detection device. A moving drive mechanism can switch the cable ends between the first clamping assembly 410 and the second clamping assembly 420. The cable ends can be clamped by the first clamping member 411 and the second clamping member 412, or by the third clamping member 421 and the fourth clamping member 422. The corresponding first clamping conductive member and the second clamping conductive member, or the corresponding third clamping conductive member 423 and the fourth clamping conductive member 424, respectively clamp the conductor of the core wire, the shielding mesh, and the insulation layer, thereby detecting whether the conductor portion of the core wire is conductive, whether both ends of the shielding mesh are conductive, and whether the insulation layer is conductive. Specifically, firstly, two sets of clamps 200 respectively clamp the two ends of the cable and extend towards the clamping positions of the first clamping components 410 of the two sets of clamping conduction mechanisms 400. The first clamping member 411 and the second clamping member 412 move relative to each other, so that the first clamping conduction member 413 and the second clamping conduction member 414 clamp the ends of the cable. Specifically, there are three sets of the first clamping conduction member 413 and the second clamping conduction member 414, thus forming three sets of clamping positions. One set of clamping positions is used to clamp the core conductor, another set of clamping positions is used to clamp the shielding mesh, and the remaining set of clamping positions is used to clamp the insulation layer. Therefore, when the first clamping member 411 and the second clamping member 412 clamp each other, the three sets of clamping positions formed by the three sets of first clamping conduction member 413 and the second clamping conduction member 414 respectively clamp the core conductor, the shielding mesh, and the insulation layer. Under the action of the two sets of first clamping components 410, both ends of the core conductor, both ends of the shielding mesh, and both ends of the insulation layer are independently connected to the continuity detection device. This allows for the detection of whether the core conductor, the shielding mesh, and the insulation layer are conductive.

[0030] Secondly, the cable end held by the first clamp 200 extends to the corresponding clamping position of the second clamping assembly 420. The third clamping member 421 and the fourth clamping member 422 move relative to each other, causing the third clamping conductive member 423 and the fourth clamping conductive member 424 to clamp the cable end. Since there are three sets of the third clamping conductive member 423 and the fourth clamping conductive member 424, three sets of clamping positions are formed. One set of clamping positions is used to clamp the core conductor, another set is used to clamp the shielding mesh, and the remaining set is used to clamp the insulation layer. Therefore, it is possible to detect whether the shielding mesh is conductive to the core conductor, etc.

[0031] Finally, the cable end held by the other clamp 200 extends into the corresponding clamping position of the second clamping assembly 420. The third clamping member 421 and the fourth clamping member 422 move relative to each other, causing the third clamping conductor 423 and the fourth clamping conductor 424 to clamp the cable end. Therefore, the second clamping assemblies 420 of the two sets of clamping and conducting mechanisms 400 simultaneously clamp both ends of the cable. This allows both ends of the cable core wire and both ends of the shielding mesh to be simultaneously connected to the electrical testing equipment, thus enabling the detection of electrical parameters of the core wire and the shielding mesh.

[0032] Therefore, the cable continuity detection device of this embodiment can detect both ends of the cable, improve detection efficiency, and detect whether the two ends of the insulation layer are conductive, whether the two ends of the shielding mesh are conductive, as well as the conductivity and electrical parameters of the core wire.

[0033] For further details, please refer to... Figures 1 to 3 The moving drive mechanism includes two lifting cylinders 510 located at the upper end of the carrier plate, and the lifting cylinders 510 are connected to corresponding clamping and guiding mechanisms 400. Furthermore, the clamping and guiding mechanism 400 also includes a lifting plate 430, which is slidably connected to the carrier plate 300. The lifting cylinders 510 are connected to the lifting plate 430, and the first clamping assembly 410 and the second clamping assembly 420 are located on the lifting plate 430.

[0034] Furthermore, please refer to Figures 1 to 3 The drive mechanism also includes two lifting cylinders 520, with the wire clamp 200 mounted on the corresponding lifting cylinder 520. The lifting cylinder 520 can lift the wire clamp 200 individually, and in combination with the lifting cylinder 510, the clamping positions of the two ends of the cable in the first clamping component 410 and the second clamping component 420 of the two sets of clamping and conducting mechanisms 400 can be freely switched to achieve detection of various functions.

[0035] For further details, please refer to... Figure 1 The cable continuity detection device in this embodiment also includes a translation mechanism 600 disposed on the support surface 102, and a carrier plate 300 disposed on the translation mechanism 600. When the end of the cable is clamped on the clamp 200 for detection, the translation mechanism 600 pushes the carrier plate 300 to translate, so that the end of the cable can extend into the first clamping component 410 or the second clamping component 420, thereby realizing the detection of the cable.

[0036] For further details, please refer to... Figures 1 to 3The clamping and conducting mechanism 400 also includes a bidirectional slide 440. The bidirectional slide 440 is a pneumatic slide with two opposing sliding surfaces. A first mounting plate 450 and a second mounting plate 460 are respectively mounted on the two slides of the bidirectional slide 440. A first clamping member 411 and a third clamping member 421 are mounted on the first mounting plate 450, and a second clamping member 412 and a fourth clamping member 422 are mounted on the second mounting plate 460. When the clamping and conducting mechanism 400 clamps a cable, the bidirectional slide 440 can simultaneously push the first clamping component 410 and the second clamping component 420 to clamp the cable.

[0037] For further details, please refer to... Figures 1 to 3 The first clamping assembly 410 and the second clamping assembly 420 have the same structure. Furthermore, the first clamping member 411, the second clamping member 412, the third clamping member 421 and the fourth clamping member 422 are each provided with a plurality of sliding grooves, and each sliding groove is provided with an elastic member 401; the first clamping guide member 413, the second clamping guide member 414, the third clamping guide member 423 and the fourth clamping guide member 424 are provided in the corresponding sliding grooves and abut against the corresponding elastic members 401.
