Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, specifically to a withstand voltage test device for insulated cables. Background Technology

[0002] Cables are commonly used signal transmission cables, widely applied in power supply and communication systems. After cable manufacturing, their insulation withstand voltage performance needs to be tested to ensure safe and normal use. However, existing cable insulation withstand voltage testing equipment cannot effectively fix the cable in place, which is detrimental to testing the cable insulation withstand voltage performance.

[0003] Chinese patent CN212083589U discloses a withstand voltage test device for testing cable insulation. The technical effects achieved by this device are as follows: the device can simultaneously clamp and fix multiple cables through the setting of the clamping structure, which can effectively fix the cables and facilitate the test of the withstand voltage performance of cable insulation. It can also test multiple cables at the same time, thus improving work efficiency.

[0004] The above-mentioned device still has the following shortcomings in practical applications:

[0005] 1. The fixing operation achieved by matching and pressing the base plate and pressure plate, and cooperating with the threaded rod and nut, has certain drawbacks. Since there are two threaded adjustment units at both ends of the base plate and pressure plate, each fixing requires tedious turning and reciprocating adjustment of the two nuts. This is redundant and troublesome in fixing the cable, which is not conducive to the efficient conduct of testing.

[0006] 2. Furthermore, since different types of cables have different diameters, the cable diameters corresponding to arc groove one and arc groove two in this device are fixed. For example, when it is necessary to clamp and fix a small diameter cable, the cable may sway left and right in the arc groove during the test due to insufficient or uneven pressure, which is not conducive to the stable conduct of cable testing.

[0007] Therefore, it is necessary to improve and refine the existing equipment to address the aforementioned issues, so that it can be better applied to the withstand voltage test of cables. Utility Model Content

[0008] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0009] Therefore, the purpose of this utility model is to provide a withstand voltage test device for insulated cables, so as to solve the problems of the existing withstand voltage test devices for insulated cables mentioned in the background art, which are cumbersome to operate and can only be fixed for cables of a fixed size.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a withstand voltage test device for insulated cables, comprising a base, wherein a clamping mechanism is provided at one end of the upper part of the base and a withstand voltage tester body that cooperates with the clamping mechanism is provided at the other end;

[0011] The clamping mechanism includes a base plate fixed to the upper end of the base. A first positioning seat is fixed to the upper end of the base plate. The upper part of the first positioning seat has several triangular slots I along its length direction. A second positioning seat is arranged directly above the first positioning seat. The bottom of the second positioning seat has several triangular slots II that are perpendicular to the triangular slots I along its length direction. Guide columns are vertically fixed on both sides of the upper end of the base plate, and the second positioning seat is vertically slidably mounted on the guide columns. A top plate is fixed to the top of the guide columns directly above the second positioning seat. A threaded screw is vertically threaded to the center of the top plate, and the bottom of the threaded screw is rotatably mounted on the upper end of the second positioning seat. A handwheel is also fixed to the top of the threaded screw.

[0012] In a preferred embodiment of the withstand voltage testing device for insulated cables described in this utility model, the second positioning seat has slides fixed at both ends and slidably connected to the guide column.

[0013] In a preferred embodiment of the withstand voltage testing device for insulated cables described in this utility model, the top of the second positioning seat has a bearing that is rotatably connected to the bottom of the threaded screw, and the middle part of the first positioning seat has a nut that is threadedly matched with the threaded screw.

[0014] In a preferred embodiment of the withstand voltage testing device for insulated cables described in this utility model, a rocker arm is also fixed to one side of the top of the handwheel.

[0015] As a preferred embodiment of the withstand voltage testing device for insulated cables described in this utility model, anti-slip pads are also provided on the inner sides of the first and second triangular slots.

[0016] As a preferred embodiment of the withstand voltage testing device for insulated cables described in this utility model, the detection output end of the withstand voltage tester body has a detection probe connected by a wire, a winding rod for guiding the wire of the detection probe is provided on one side of the upper end of the withstand voltage tester body, and a probe clamping component for clamping and positioning the detection probe is provided on the other side of the upper end of the withstand voltage tester body.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this insulated cable withstand voltage test device, multiple cables can be placed into the sequentially arranged triangular slots at the same time, which is conducive to the simultaneous testing of multiple cables. Then, by rotating the handwheel and the screw, the second positioning seat is driven to descend stably with the cooperation of the top plate, nut, slide and guide column, and the cable is clamped and positioned by the triangular slots one and two. When unloading, only the handwheel needs to be reversed. The operation is simple and the control is stable. There is no need for cumbersome turning and adjustment, which is conducive to the efficient conduct of the test work.

[0018] Furthermore, through the ingenious cooperation of triangular slot one and triangular slot two, it can clamp and position cables of different diameters according to the actual needs of the test. This not only improves the applicability of the clamping device, but also avoids wobbling caused by mismatched clamping, which is conducive to the stable conduct of cable testing.

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Figures 1-3 The diagram shown is a complete structural schematic of a withstand voltage testing device for insulated cables according to this utility model. Please refer to [link / reference]. Figures 1-3 This embodiment of an insulated cable withstand voltage testing device includes a base 10, with a clamping mechanism 20 at one end of the upper part of the base 10 and a withstand voltage tester body 30 cooperating with the clamping mechanism 20 at the other end. In this embodiment, the test output end of the withstand voltage tester body 30 has a test probe 301 connected by a wire. A winding rod 40 for guiding the wire of the test probe 301 is provided on one side of the upper end of the withstand voltage tester body 30, and a probe clamping member 50 for clamping and positioning the test probe 301 is also provided on the other side of the upper end of the withstand voltage tester body 30. Here, the probe clamping member 50 and the test probe 301 are matched with each other. When not in use, the test probe 301 can be positioned and stabilized by the probe clamping member 50 to prevent the test probe 301 from falling and being damaged.

[0027] The clamping mechanism 20 includes a base plate 201 fixed to the upper end of the base 10. A first positioning seat 202 is fixed to the upper end of the base plate 201. The upper part of the first positioning seat 202 has several triangular slots 202a along its length. A second positioning seat 203 is arranged directly above the first positioning seat 202. The bottom of the second positioning seat 203 has several triangular slots 203a that are perpendicular to the triangular slots 202a. Guide posts 204 are vertically fixed on both sides of the upper end of the base plate 201. The second positioning seat 203 is vertically slidably mounted on the guide posts 204. A top plate 205 is fixed to the top of the guide posts 204 directly above the second positioning seat 203. A threaded screw 207 is vertically threaded to the center of the top plate 205. The bottom of the threaded screw 207 is rotatably mounted on the upper end of the second positioning seat 203. A handwheel 208 is also fixed to the top of the threaded screw 207.

[0028] Furthermore, the second positioning seat 203 has slide seats 2031 fixed at both ends and slidably connected to the guide post 204. Through the cooperation between the guide post 204 and the slide seats 2031, the second positioning seat 203 moves up and down more smoothly and linearly, and the operation is more stable.

[0029] The top of the second positioning seat 203 has a bearing 2032 that is rotatably connected to the bottom of the threaded screw 207. The middle part of the first positioning seat 202 has a nut 206 that is threadedly matched with the threaded screw 207. In this embodiment, the nut 206 is a ball nut. The threaded screw 207 and the nut 206 are threaded screw pairs. With the cooperation of the nut 206, the bearing 2032, the threaded screw 207 and the top plate 205, when the threaded screw 207 is rotating, it can push the second positioning seat 203 to move up and down, thereby forming a clamping action and a disengaging action with the first positioning seat 202.

[0030] It should be noted that the ball screw pair used in this embodiment has the characteristics of high adjustment accuracy, strong load-bearing capacity, and good static locking performance, which is beneficial to the flexible adjustment of the second positioning seat 203 and the clamping stability of the cable.

[0031] Furthermore, a rocker arm 2081 is fixed to one side of the top of the handwheel 208. The handwheel 208 makes it easier, more efficient and stable for the operator to rotate the threaded screw 207. The eccentric rocker arm 2081 on the upper end of the handwheel 208 makes it faster to rotate the threaded screw 207, which is conducive to the rapid progress of the testing work.

[0032] The inner sides of the triangular clamping slots 202a and 203a are also equipped with anti-slip pads 209. These pads effectively increase the contact friction between the cable and the clamping slots 202a and 203a, resulting in a tighter and more stable clamping without causing hard pressure damage to the cable surface. In actual use, multiple cables can be placed simultaneously into the sequentially arranged triangular clamping slots 202a, facilitating simultaneous testing of multiple cables. Then, rotating the handwheel 208 and the threaded screw 207, along with the cooperation of the top plate 205, nut 206, slide 2031, and guide post 204, drives the second positioning seat 203 to descend stably, clamping and positioning the cable through the triangular clamping slots 202a and 203a. Removal is simple; just reverse the handwheel 208. The operation is simple and the control is stable, eliminating the need for cumbersome tightening and adjustment, thus promoting efficient testing.

[0033] Furthermore, through the ingenious cooperation of triangular slot 1 202a and triangular slot 2 203a, it can clamp and position cables of different diameters according to the actual needs of the test. This not only improves the applicability of the clamping device, but also avoids wobbling caused by mismatched clamping, which is conducive to the stable conduct of cable testing.

[0034] In summary, the withstand voltage testing device for insulated cables of this embodiment allows multiple cables to be placed simultaneously into the sequentially arranged triangular slots 202a, facilitating simultaneous testing of multiple cables. Then, rotating the handwheel 208 and the threaded screw 207, along with the cooperation of the top plate 205, nut 206, slide block 2031, and guide post 204, drives the second positioning seat 203 to descend stably. The cable is then clamped and positioned by the triangular slots 202a and 203a. Removal is achieved simply by reversing the handwheel 208. The device is simple to operate, provides stable control, and promotes efficient testing.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
