Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to a cable conductor resistance sample preparation device. Background Art

[0002] Cable conductor resistance refers to the resistance inside the cable conductor, which is the resistance force generated when current flows in the conductor. The size of the cable conductor resistance depends on factors such as the conductor material, length, cross-sectional area and temperature.

[0003] In the prior art, it is usually necessary to sample the cable conductor resistance. The important reasons for sampling the cable conductor resistance are: 1. Quality control. By sampling and inspecting the cable conductor resistance, problems that may occur in the manufacturing process can be discovered and eliminated in a timely manner to ensure that the quality of the cable meets the standard requirements; 2. Determine whether the resistance meets the requirements. Cable conductor resistance is one of the important indicators of cable performance. Sampling can verify whether the cable conductor resistance meets the design requirements, such as whether the cable conductor resistance is within a safe range, thereby ensuring that the cable can transmit current normally during use; 3. Optimize performance. Sampling can help manufacturers understand the actual situation of cable conductor resistance and adjust production processes and material selection in a timely manner to optimize cable performance.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of one or more embodiments of this specification clearer, the technical solutions of one or more embodiments of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of one or more embodiments of this specification.

[0040] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0041] Figure 1 This is a schematic diagram of the structure of a cable conductor resistance sample preparation device provided in an embodiment of this specification. Figure 2 A structural diagram of a fixing module provided in an embodiment of this specification is shown in FIG. Figure 1-2 As shown, the cable conductor resistance sample preparation device includes a base plate 1 and a fixing module and a cutting module arranged on the base plate 1. The fixing module includes two oppositely arranged baffles 2, a first motor 3, a first screw 4 and at least one embracing structure. The first motor 3 is arranged outside the baffle 2, and the first motor 3 is connected to the embracing structure located between the two baffles 2 through the first screw 4. The first screw 4 moves under the drive of the first motor 3. The embracing structure clamps and fixes the cable conductor to be sampled under the movement of the first screw 4.

[0042] Furthermore, a push plate 5 is provided on the side of the first lead screw 4 away from the first motor 3 ; the embracing structure clamps and fixes the cable conductor to be sampled under the push of the push rod 5 .

[0043] In the embodiment of the present specification, the cutting module includes a first side plate 12, a slide bar 13, a second lead screw 14 and a second motor 15. The first side plate 12 is arranged at the outlet end of the cable conductor to be sampled in the embracing structure. The first side plate 12 is provided with a cutter, which is used to cut the cable conductor to be sampled. The slide bar 13 and the second lead screw 14 are arranged below the first side plate 12, and the second motor 15 is connected to the first side plate 12 through the second lead screw 14.

[0044] The second lead screw 14 moves under the drive of the second motor 15 , and the first side plate 12 moves on the slide bar 13 under the movement of the second lead screw 14 .

[0045] When the device provided in the embodiment of the present specification is used to sample the resistance of a cable conductor, the cable conductor can be passed through the embracing structure in the fixing module and the cutter of the first side plate 12 in sequence, and then the first motor 3 is turned on, and the first lead screw 4 moves driven by the first motor 3, and then the embracing structure can be pushed by the push plate 5, and under the push of the push plate 5 and the limiting of the limit ring 9, the embracing structure can hold and fix the cable conductor; then the first motor 3 can be turned off and the second motor 15 can be turned on, and the second lead screw 14 can move the first side plate 12 on the slide rod 12 driven by the second motor 15, and then the cutter in the first side plate 12 cuts the cable conductor, so that the ring-cut part of the cable conductor is slowly pulled out of the conductor along with the insulating layer, thereby realizing the sampling of the resistance of the cable conductor.

[0046] Furthermore, in order to protect the cable from damage and ensure the stability of the cable conductor clamped by the embracing structure, a protective pad 11 may be provided in the clamping plate 6 in the embodiment of the present specification.

[0047] In the embodiment of the present specification, in order to further clamp and fix the cable conductor to be sampled, the fixing module may include two embracing structures. That is, the cable conductor may pass through the two embracing structures in sequence and then pass through the cutter of the first side plate 12.

[0048] like Figure 2 As shown, the embracing structure includes a clamping plate 6, a push-pull rod structure and a limiting structure. The clamping plate 6 includes a first semicircular clamping plate and a second semicircular clamping plate arranged opposite to each other. The push-pull rod structure includes a first push-pull rod 7 and a second push-pull rod 71 arranged opposite to each other, and the push-pull structure also includes a gear 8 arranged between the two push-pull rods. The limiting structure includes two limiting rings 9 and a limiting rod 10 passing through the two limiting rings 9, and the limiting rod 10 is fixed between the two baffles 2.

[0049] The bottom of the first semicircular clamping plate is connected to the first push-pull rod 7, and the bottom of the second semicircular clamping plate is connected to the second push-pull rod 71. Two limiting rings 9 are fixed on the tops of the two semicircular clamping plates respectively.

[0050] One end of the first semicircular clamping plate is connected to the first lead screw 4. The first semicircular clamping plate moves in a direction away from the first lead screw 4 under the movement of the first lead screw 4. If a push plate 5 is provided on the side of the first lead screw 4 away from the first motor 3, the movement of the first lead screw 4 can cause the push plate 5 to push the first semicircular clamping plate to move in a direction away from the first lead screw 4. The first push-pull rod 7 acts on the gear 8 under the movement of the first semicircular clamping plate, so that the gear 8 drives the second push-pull rod 71 to move. The second semicircular clamping plate moves in a direction close to the first lead screw 4 under the movement of the second push-pull rod 71.

[0051] Furthermore, the movement of the semicircular clamping plate drives the limiting ring 9 to move on the limiting rod 10. The limiting ring 9 limits the semicircular clamping plate through the limiting rod 10.

[0052] Figure 3 A schematic diagram of the structure of a first side plate provided in an embodiment of this specification, such as Figure 3 As shown, the first side plate 12 is also provided with a threaded rod 17 and a knob 18. The cutters provided on the first side plate include an upper cutter 16 and a lower cutter 19 located below the upper cutter 16. The two ends of the threaded rod 17 are connected to the knob 18 and the upper cutter 16 respectively.

[0053] The knob 18 is used to rotate the threaded rod 17 so as to move the threaded rod 17 toward the lower cutter 19. The upper cutter 16 moves toward the lower cutter 19 under the movement of the threaded rod 17.

[0054] Before starting the second motor 15, the knob 18 can be rotated to move the threaded rod 17 toward the lower cutter 19, and then the upper cutter 16 approaches the lower cutter 19 under the movement of the threaded rod 17, so that the upper and lower cutters fix the cable conductor to be sampled.

[0055] Figure 4 A schematic diagram of a structure with two side panels provided in an embodiment of this specification, such as Figure 4As shown, the cutting module in the embodiment of the present specification also includes a second side plate 20 arranged opposite to the first side plate 12. The second side plate 20 is arranged above the slide bar 13 and the second lead screw 14, and the second motor 15 is also connected to the second side plate 20 through the second lead screw 14. The second side plate is provided with a cutter, which is used to cut the cable conductor to be sampled. The second side plate 20 moves on the slide bar 13 toward the direction close to the first side plate 12 under the movement of the second lead screw 14.

[0056] It is understandable that after the second motor 15 is turned on, the second lead screw 14 can drive the first side plate 12 and the second side plate 20 to move closer to each other on the slide bar 13 under the drive of the second motor 15. In this way, the two side plates can strip the cable conductor insulation layer more efficiently.

[0057] In the embodiments of this specification, Figure 4 As shown, the cutting module further includes a transmission structure located between the two side panels. The transmission structure includes a turntable 21 and two movable plates. The turntable 21 is arranged on the bottom plate 1; one end of the two movable plates is respectively connected to the bottom of the two side panels, and the other end of the two movable plates is connected to the turntable 21. The first movable plate 22 can be connected to the bottom of the first side panel 12, and the second movable plate 23 can be connected to the bottom of the second side panel 20.

[0058] The movement of the first side plate 12 drives the transmission structure to move, thereby causing the second side plate 20 to move synchronously with the first side plate 12 ; or the movement of the second side plate 20 drives the transmission structure to move, thereby causing the first side plate 12 to move synchronously with the second side plate 20 .

[0059] The movement of the first side panel 12 can drive the movement of the first movable panel 22, and the first movable panel 22 drives the movement of the second movable panel 23 through the rotating disk 21, thereby driving the movement of the second side panel 20. Similarly, the movement of the second side panel 20 can drive the movement of the second movable panel 23, and the second movable panel 23 drives the movement of the first movable panel 22 through the rotating disk 21, thereby driving the movement of the first side panel 12.

[0060] The transmission structure can better separate the insulation layer of the cable conductor, and then sample the resistance of the cable conductor. For example, if there is a problem with the connection between the first side plate 12 and the second lead screw 14, the second lead screw 14 cannot drive the first side plate 12 to move. At this time, the second lead screw 14 can drive the second side plate 20 to move, and then the transmission structure can drive the first side plate 12 to move. The same is true when there is a problem with the connection between the second side plate 20 and the second lead screw 14, which will not be repeated here.

[0061] In order to further clamp and fix the cable conductor to be sampled, the cable conductor resistance sample preparation device in the embodiment of this specification may include two fixing modules, wherein the cutting module is arranged between the two fixing modules. The embracing structure of the two fixing modules is used to clamp and fix the cable conductor to be sampled. The cutting module is used to cut the cable conductor between the two fixing modules.

[0062] The working process of the cable conductor resistance sample preparation device including two fixed modules is described as follows:

[0063] The cable conductor to be sampled is passed through the embracing structure in one of the fixing modules, the cutter on the side plate in the cutting module, and the embracing structure in another fixing module in turn; then, the motor in the fixing module is used to clamp and fix the cable conductor to be sampled, and the knob in the cutting module is rotated to fix the cable conductor to be sampled by the cutter in the side plate; then, the motor of the cutting module is turned on to move the side plate of the cutting module to strip off the insulation layer of the cable conductor.

[0064] In the embodiments of the present specification, the embracing structure in the fixing module can effectively clamp and fix the cable conductor under the push of the first lead screw and the limiting of the limiting ring, and then realize the resistance sampling of the cable conductor under the cutting of the cutting module.

[0065] In an embodiment of the present specification, the cutting module may include two side plates and a transmission structure arranged between the two side plates. Under the movement of the second lead screw, based on the transmission structure, the two side plates can move stably and synchronously, thereby improving the stability of cable conductor resistance sampling.

[0066] In the embodiments of the present specification, the cable conductor resistance sampling device may include two fixing modules and a cutting module arranged between the two fixing modules; the two fixing modules jointly clamp and fix the cable conductor to be sampled, thereby improving the stability of the cable conductor.

[0067] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
