Description

Technical Field

[0001] This utility model relates to the field of cable clamping structures, and in particular to a clamping device for conductor detection. Background Technology

[0002] During cable maintenance and repair, cable testing is necessary to ensure its performance during use. Traditional cable testing methods involve manual clamping (such as wire bundling or manual fixing), which is time-consuming and makes it difficult to ensure consistent testing conditions, resulting in poor repeatability of results.

[0003] The utility model disclosed in CN119496071A is a wiring device for power maintenance with anti-retraction mechanism, including a base, two anti-retraction mechanisms and two cutting mechanisms. Each anti-retraction mechanism includes a chuck, a moving component, a guiding component and multiple jaws. Each cutting mechanism includes a U-shaped frame, a telescopic component, a pushing component, a transmission component, a rotating component, two sliding seats and two cutters. By setting the anti-retraction mechanism, the ends of two disconnected cables can be clamped and fixed, effectively preventing the cables from retracting due to their own weight. At the same time, the moving component can drive the chucks on both sides to move closer to each other, so that the cables on both sides can move closer to each other.

[0004] Although the above solution achieves the gripping and fixing of the cable, it only uses four claws for clamping, resulting in a small clamping contact area and poor stability of the cable clamping state. The cable is prone to positional displacement during the experiment. Furthermore, the clamping structure is limited in the diameter of the cable it can clamp, and cannot reliably clamp cables of various diameters, thus limiting its versatility. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, such as poor stability of cable clamping and limited versatility, and to provide a clamping device for conductor detection.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A clamping device for conductor testing includes a sliding guide rail and multiple cable testing clamps. Each cable testing clamp includes a sliding bracket and a clamping body. The bottom of the sliding bracket is slidably connected to the sliding guide rail, and the top is connected to the clamping body. The clamping body is a barrel-shaped structure with one side open and the interior hollow. Multiple bolt holes are evenly provided on the side of the clamping body along the same circumference, and multiple cable core wiring holes are provided on the bottom surface. Each bolt hole is connected to a bolt, and each bolt end face is connected to an arc plate located inside the clamping body. The arc plates corresponding to the bolt holes in the same circumference fit together in pairs to form an annular clamping cavity that fits with the conductor to be tested.

[0008] Furthermore, the side of the clamping body is provided with multiple sets of bolt holes evenly distributed along the same circumference. Each set of bolt holes corresponds to each other in the longitudinal position of the clamping body, and the two ends of each arc plate are respectively connected to the bolts in each set of bolt holes that correspond to the longitudinal position of the clamping body.

[0009] Furthermore, the outer surface of the arc plate is provided with a U-shaped fixing groove, and the end face of the bolt is provided with a correspondingly shaped connecting part, which is located in the fixing groove.

[0010] Furthermore, the side of the clamping body is provided with eight bolt holes evenly distributed along the same circumference.

[0011] Furthermore, multiple cable core wiring holes are distributed at the center and around the bottom surface of the clamping body.

[0012] Furthermore, the sliding bracket includes a left sub-bracket and a right sub-bracket, which are connected to each other and clamped on the outside of the clamping body. Both the left sub-bracket and the right sub-bracket include a semi-circular clamp and a movable base. Both ends of the clamp are provided with bolt connection seats. The movable base extends along one end of the clamp and then bends to form a sliding block that cooperates with the sliding guide rail.

[0013] The sliding block is provided with a fixing hole, and the sliding block can be detachably installed on the sliding guide rail by screws passing through the fixing hole.

[0014] Furthermore, the cable core wiring hole includes a conductor core end face energized screw hole and multiple conductor side face energized wiring holes;

[0015] The bottom end of the arc plate is welded or screwed to fix the wire, which is then led out from the power connection hole on the side of the conductor.

[0016] Furthermore, the sliding bracket is connected to the middle of the clamping body.

[0017] Furthermore, the arc plate is made of copper, and an insulating material covers the space between the clamping body and the sliding bracket, so that the conductor under test and the sliding bracket are electrically isolated and do not form a circuit.

[0018] Furthermore, the cable testing clamps are in the form of two, which are detachably fixed to both ends of the conductor to be tested;

[0019] The clamping device for conductor testing is used for testing cables, rods, and pipes.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] (1) This solution uses a barrel-shaped structure with an opening on one side and a hollow interior as the clamping body, which is fitted onto the end of the conductor to be tested. Through the bolts in the bolt holes evenly distributed around the circumference of the clamping body, the arc plate on the end face of the bolt is gradually driven to approach the surface of the conductor to be tested on the inner side of the clamping body. The arc plates of each bolt distributed around the circumference cooperate with each other to clamp the conductor to be tested on the circumferential surface. This solution can flexibly select and adjust each clamping structure composed of bolts and arc plates according to the different diameters of the conductor to be tested. It is stable, reliable and versatile.

[0022] (2) When the conductor to be tested is clamped by the arc plate, each arc plate is adjusted from the center of the clamping body by the corresponding multiple bolts to achieve reliable clamping at both ends and ensure the stability of the clamping.

[0023] (3) This solution is applicable to the testing of conductors such as cables, rods and pipes.

[0024] (4) In this scheme, an insulating material is attached between the clamping body and the sliding bracket to form electrical isolation between the conductor to be tested and the guide rail, so that no circuit is formed. Attached Figure Description

[0040] Example 1

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a clamping device for conductor detection, including a sliding guide rail 1 and multiple cable detection clamps. The cable detection clamps include a sliding bracket 2 and a clamping body 3. The bottom of the sliding bracket 2 is slidably connected to the sliding guide rail 1, and the top is connected to the clamping body 3. The clamping body 3 is a barrel-shaped structure with one side open and the inside hollow. Multiple bolt holes 301 are evenly provided on the side of the clamping body 3 along the same circumference, and multiple cable core wiring holes 302 are provided on the bottom surface. Each bolt hole 301 is connected to a bolt 4, and the end face of each bolt 4 is connected to an arc plate 5. The arc plate 5 is located inside the clamping body 3. The arc plates 5 corresponding to the bolt holes 301 in the same circumference are matched in pairs to form an annular clamping cavity 6 that matches the conductor 7 to be tested.

[0042] This solution uses a barrel-shaped structure with an opening on one side and a hollow interior as the clamping body 3, which is fitted onto the end of the conductor 7 to be tested. Through the bolts 4 in the bolt holes 301 that are evenly distributed around the circumference of the clamping body 3, the arc plate 5 on the end face of the bolt 4 is gradually moved closer to the surface of the conductor 7 to be tested inside the clamping body 3. The arc plates 5 of each bolt 4 distributed around the circumference cooperate with each other to clamp the conductor 7 to be tested on the circumferential surface of the conductor 7 to be tested.

[0043] This solution allows for flexible selection and adjustment of various clamping structures consisting of bolts 4 and arc plates 5, depending on the diameter of the conductor 7 to be tested. The clamping structure is stable, reliable, and highly versatile.

The two ends of each arc plate 5 are respectively connected to the bolts 4 in each set of bolt holes 301 that correspond to the longitudinal position of the clamping body 3.

[0045] In this design, when clamping the conductor 7 to be tested using the arc plates 5, the distance between each arc plate 5 and the axis of the clamping body 3 is adjusted by multiple corresponding bolts 4 to achieve reliable clamping at both ends and ensure the stability of the clamping. The wire is welded or screwed to the bottom end of the arc plate and led out from the cable core connection hole 302.

[0046] Optional, such as Figure 6 and Figure 7 As shown, the outer surface of the arc plate 5 is provided with a convex-shaped fixing groove 501, and the end face of the bolt 4 is provided with a corresponding connecting part, which is located in the fixing groove 501.

[0049] An insulating material is applied between the clamping body and the sliding bracket to create electrical isolation between the conductor under test and the guide rail, preventing a circuit from forming.

[0050] Optionally, multiple cable core wiring holes 302 are distributed at the center and around the bottom surface of the clamping body 3. Specifically, the bottom surface of the clamping body 3 has a conductor core end face energized screw hole and multiple conductor side energized wiring holes. The conductor side energized wiring holes are distributed around a circumference of the bottom surface of the clamping body 3 to realize the wiring of each wire core in the conductor 7 under test; the conductor core end face energized screw hole can be connected to the main body bolt 8. The nut of the main body bolt 8 is located in the middle, and both sides are threaded. One side is used to connect to the clamping body 3, and the other side is used to connect to other test fixtures.

[0051] Optional, such as Figure 8 As shown, the sliding bracket 2 includes a left sub-bracket and a right sub-bracket. The left sub-bracket and the right sub-bracket are connected to each other and clamped on the outside of the clamping body 3. Both the left sub-bracket and the right sub-bracket include a semi-circular clamp 201 and a movable base 202. Both ends of the clamp 201 are provided with bolt 4 connecting seats. The movable base 202 extends along one end of the clamp 201 and then bends to form a sliding block that cooperates with the sliding guide rail 1.

[0052] The sliding block is provided with a fixing hole, and the sliding block can be detachably installed on the sliding guide rail 1 by screws passing through the fixing hole.

[0053] Preferably, the sliding bracket 2 is connected to the middle of the clamping body 3.

[0054] In this embodiment, the sliding bracket 2 is fixed between two sets of bolt holes 301 in the clamping body 3.

[0055] In this embodiment, the arc plate 5 is made of copper.

[0056] In this embodiment, there are two cable testing clamps, which are detachably fixed at both ends of the conductor 7 to be tested.

[0057] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
