[0002] The wire stripper is a common tool used in the field of power engineering and electrical maintenance, which mainly strips the insulating shell of the cable to expose the core wire for connection between cables. The existing high-voltage cable is composed of a hard single-layer shell, a soft plastic film multi-layer shielding layer, a hard plastic film multi-layer shielding layer, and a core wire. Unlike the common single-layer rubber insulation shielding layer, this poses many problems for wire stripping.

[0003] Conventional manual or automatic wire strippers rely on clamping devices and ring-shaped cutters to strip the wire in the axial direction of the cable, which is not suitable for this high-voltage cable. When the clamping device is located at the soft plastic film multi-layer shielding layer of the high-voltage cable, it will cause the soft plastic film to fall off, resulting in a smaller stripped wire diameter than the set wire diameter.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] An embodiment of the present invention provides a press-type stepped stripping tool for high-voltage cable joints, comprising: an upper pressing component and a lower pressing component, wherein the upper pressing component and the lower pressing component have the same structure; the upper pressing component includes a handle, which is connected to the main body, and a high-voltage cable groove runs through the handle and the main body; the high-voltage cable groove located within the main body has a dual-diameter cutter, which includes a coarse wire diameter cutter group and a fine wire diameter cutter group, wherein the coarse wire diameter cutter group includes a coarse wire diameter ring cutter and a coarse wire diameter straight cutter, and the fine wire diameter cutter group includes a fine wire diameter ring cutter and a fine wire diameter straight cutter.

[0034] Below, in conjunction with Figure 1 An example of a press-type stepped stripper for describing the above-mentioned high-voltage cable joint.

[0035] As shown in Figure 1 The extrusion-type stepped stripping tool for high-voltage cable joint comprises an upper pressing member 1 and a lower pressing member 2. The upper pressing member 1 and the lower pressing member 2 have the same structure. When the tool is used to strip the high-voltage cable 3, the high-voltage cable 3 is placed between the lower pressing member 2 and the upper pressing member 1, as shown in Figure 1

[0036] Figure 2 The structural schematic diagram of the upper pressing member 1 from the first perspective is shown in Figure 3 The structural schematic diagram of the upper pressing member 1 from the second perspective is shown in

[0037] As shown in Figure 2 and Figure 3 The upper pressing member 1 comprises a handle 11, and the handle 11 is connected to a main body 12. The handle 11 and the main body 12 are internally provided with a high-voltage cable slot 15.

[0038] The high-voltage cable slot 15 in the main body 12 is provided with a double-diameter cutter, which comprises a thick-wire-diameter cutter group and a thin-wire-diameter cutter group.

[0039] As shown in Figure 3 The thick-wire-diameter cutter group comprises a thick-wire-diameter ring cutter 13 and a thick-wire-diameter straight cutter 14, and the thin-wire-diameter cutter group comprises a thin-wire-diameter ring cutter 16 and a thin-wire-diameter straight cutter 17.

[0040] For example, the thin-wire-diameter straight cutter 14 is located at the end of the high-voltage cable slot 15 in the main body, and the thin-wire-diameter ring cutter 16, the thick-wire-diameter straight cutter 14 and the thick-wire-diameter ring cutter 13 are sequentially connected to the handle 11 in the direction of the thin-wire-diameter straight cutter 17.

[0041] For example, the diameter of the thick-wire-diameter ring cutter 13 is larger than that of the thin-wire-diameter ring cutter 16. Here, the diameter refers to the diameter of the corresponding inner circle of the circular ring formed by the cutting edges. For example, when the upper pressing member 1 and the lower pressing member 2 are combined (pressed together), the thick-wire-diameter ring cutter 13 in the upper pressing member 1 and the thick-wire-diameter ring cutter 13 in the lower pressing member 2 form a ring-shaped cutter, and the diameter of the corresponding circle of the cutting edges of the ring-shaped cutter is the diameter of the thick-wire-diameter ring cutter 13. The definition of the diameter of the thin-wire-diameter ring cutter 16 is similar to that of the thick-wire-diameter ring cutter 13, which will not be described here. In this way, the diameter of the thick-wire-diameter ring cutter 13 determines the corresponding thick-wire-diameter (i.e., the larger one of the required diameters of the high-voltage cable 3), and the diameter of the thin-wire-diameter ring cutter 16 determines the corresponding thin-wire-diameter (i.e., the smaller one of the required diameters of the high-voltage cable 3).

[0042] For example, the depth of the thick-wire-diameter straight cutter 14 is smaller than that of the thin-wire-diameter straight cutter 17.

[0043] For example, the depth of the thick-wire-diameter straight cutter 14 is the same as that of the thick-wire-diameter ring cutter 13, which is denoted as the first depth, and the depths of the two can be strictly equal or approximately equal.​

[0044] For example, the depth of the thin wire diameter straight blade 17 and the thin wire diameter ring blade 16 is consistent, as noted as the second depth, and the two depths can be strictly equal or approximately equal.

[0045] In this way, the first depth is smaller than the second depth, and when cutting, the thin wire diameter straight blade 17 and the thin wire diameter ring blade 16 cooperate to cut to one wire diameter (thin wire diameter) of the high-voltage cable 3 based on the second depth, while the thick wire diameter straight blade 14 and the thick wire diameter ring blade 13 cooperate to cut to another wire diameter (thick wire diameter) of the high-voltage cable 3 based on the first depth. The stripped joint can have both wire diameters required when adapting the cable wiring, overcoming the problem of the prior art that the soft plastic film falls off when stripping, resulting in a stripped wire diameter smaller than the set wire diameter.

[0046] Next, a preferred embodiment of the pressing type step stripping tool for the high-voltage cable joint described above is described.

[0047] As shown in the accompanying drawings, Figure 1 The pressing type step stripping tool for the high-voltage cable joint includes an upper pressing piece 1 and a lower pressing piece 2, and the high-voltage cable is located between the lower pressing piece 2 and the upper pressing piece 1 when stripping. As shown in the accompanying drawings, Figure 2 、 3 The upper pressing piece 1 includes a handle 11, a main body 12, and a thick wire diameter ring blade 13, a thick wire diameter straight blade 14, a high-voltage cable slot 15, a thin wire diameter ring blade 16, and a thin wire diameter straight blade 17. The cable slot 15 is a high-voltage cable placement space that penetrates the handle 11 and the main body 12. The thick wire diameter ring blade 13, the thick wire diameter straight blade 14, the thin wire diameter ring blade 16, and the thin wire diameter straight blade 17 are located in the high-voltage cable slot 15 in the main body 12, which can ensure the safety of the operator.

[0048] The thick wire diameter ring blade 13 and the thick wire diameter straight blade 14 form a thick wire diameter blade group for stripping the first wire diameter, and the thin wire diameter ring blade 16 and the thin wire diameter straight blade form a thin wire diameter blade group for stripping the second wire diameter. The thin wire diameter straight blade 17 is located at the end of the high-voltage cable slot 15 in the main body 12, and the thin wire diameter straight blade 17 is sequentially connected with the thin wire diameter ring blade 16, the thick wire diameter straight blade 14, and the thick wire diameter ring blade 13 in the direction of the handle 11. The pressing type step stripping tool for the high-voltage cable joint has a diameter of the thick wire diameter ring blade 13 larger than that of the thin wire diameter ring blade 16, and a blade depth of the thick wire diameter straight blade 14 smaller than that of the thin wire diameter straight blade 17.

[0049] As shown in the accompanying drawings, Figure 4 The lower pressing piece 2 has the same structure as the upper pressing piece 1. Each of the upper pressing piece 1 and the lower pressing piece 2 has double-diameter cutters, and when used, the upper and lower cutters cooperate to complete the stripping.

[0050] The pressing type step stripping tool for the high-voltage cable joint in the preferred embodiment avoids manual stripping and ensures the safety of the operator.

[0051] The embodiment of the present application also provides a stripping method of the pressing type step-by-step stripping tool for high voltage cable joint, wherein the high voltage cable to be stripped is placed in the high voltage cable groove between the upper pressing member and the lower pressing member, and the end of the high voltage cable is aligned with the head of the main body, and the main body of the upper pressing member and the lower pressing member is pressed by the vice to complete the stripping.

[0052] For example, the stripping is performed by the cooperation of the thick wire diameter ring cutter and the thick wire diameter straight cutter to strip the high voltage cable to the first wire diameter, and the cooperation of the thin wire diameter ring cutter and the thin wire diameter straight cutter to strip the high voltage cable to the second wire diameter.

[0053] For example, the stripping is performed according to the first wire diameter size required by the high voltage cable to determine the diameter of the thick wire diameter ring cutter and the depth and length of the thick wire diameter straight cutter, the diameter of the thick wire diameter ring cutter determines the stripped wire diameter size, and the thick wire diameter straight cutter determines the length of the wire diameter size.

[0054] For example, the stripping is performed according to the second wire diameter size required by the high voltage cable to determine the diameter of the thin wire diameter ring cutter and the depth and length of the thin wire diameter straight cutter, the diameter of the thin wire diameter ring cutter determines the stripped wire diameter size, and the thin wire diameter straight cutter determines the length of the wire diameter size.

[0055] Hereinafter, a preferred embodiment of the above-mentioned stripping method is described.

[0056] The stripping method of the pressing type step-by-step stripping tool for high voltage cable joint is as follows: the high voltage cable to be stripped is placed in the high voltage cable groove between the upper pressing member and the lower pressing member, and the end of the high voltage cable is aligned with the head of the main body, and the main body of the upper pressing member and the lower pressing member is pressed by the vice to complete the stripping.

[0057] According to the above-mentioned pressing type step-by-step stripping tool for high voltage cable joint, Figures 1-4 the stripping method thereof comprises the following steps:

[0058] The high voltage cable to be stripped is placed in the high voltage cable groove between the upper pressing member 1 and the lower pressing member 2, and the end of the high voltage cable 3 is aligned with the head of the main body 12, and the main body 12 of the upper pressing member 1 and the lower pressing member 2 is pressed by the vice to complete the stripping, and the stripped high voltage cable is shown in the attached figure. Figure 5 The high voltage cable is once formed into the step shape of two wire diameters.

[0059] The diameter of the thick wire diameter ring cutter 13 and the depth and length of the thick wire diameter straight cutter 14 are determined according to the first wire diameter size required by the high voltage cable, the diameter of the thick wire diameter ring cutter 13 determines the stripped wire diameter size, and the thick wire diameter straight cutter 14 determines the length of the wire diameter size.

[0060] The diameter of the fine wire diameter ring cutter 16 and the depth and length of the fine wire diameter straight cutter 17 are determined according to the second wire diameter required. The diameter of the fine wire diameter ring cutter 16 determines the wire diameter to be stripped, and the fine wire diameter straight cutter 17 determines the length of that wire diameter.

[0061] The coarse wire diameter ring cutter 13 and the coarse wire diameter straight cutter 14 work together to strip out the first type of wire diameter, while the fine wire diameter ring cutter 16 and the fine wire diameter straight cutter 17 work together to strip out the second type of wire diameter, so as to strip out both types of wire diameter at the same time and improve work efficiency.

[0062] The wire stripping method of the press-type stepped stripping tool for high-voltage cable joints in this embodiment can strip two wire diameters from high-voltage cables, improving work efficiency and having strong practical value.

[0063] Furthermore, embodiments of the present invention also provide a compression-type stepped stripping tool for high-voltage cable connectors with another structure, which will be described below in conjunction with... Figures 6-11 To describe the other structure mentioned above.

[0064] like Figure 6 The high-voltage cable connector shown is a compression-type stepped stripping tool consisting of two parts: an upper pressing component 10 and a lower pressing component 20. The lower pressing component 20 has the same structure as the upper pressing component 1. Here, the structure of the upper pressing component 10 is described as an example, and the lower pressing component 20 with the same structure will not be described in detail.

[0065] like Figure 7 As shown, the upper pressure component assembly 10 includes three parts: a left pressure component 110, a right pressure component 120, and a double-diameter cutter 130.

[0066] like Figure 8 As shown, one end of the left pressure member 110 is a quarter-circular annular first grip 21, and the other end is a cuboid first body 22, with the first grip 21 connected to the first body 22. Furthermore, above the first body 22 (on the side away from the first cable trough) is a cuboid first fixing block 23, with a first fixing hole 24 perpendicular to the wall surface. The first fixing hole 24 is a threaded through hole; for example, the first fixing block 23 may have two first fixing holes 24, located symmetrically at the center of the first fixing block 23. Additionally, the first cable trough 25 is a space for placing high-voltage cables, passing through the first grip 21 and the interior of the first body 22. The wall surface is the wall surface that contacts the left pressure member 110 and the right pressure member 120 during installation.

[0067] like Figure 9As shown, the right pressing piece 120 structure is mirror-symmetrical with the left pressing piece 110, one end of the right pressing piece 120 is a quarter circular ring-shaped second handle 31, the other end of the right pressing piece 120 is a cuboid-shaped second main body 32, the lower side (the side away from the second cable slot) of the second main body 32 is a cuboid-shaped second fixed block 33, a second fixed hole 34 is vertically opened on the second fixed block 33, and the second fixed hole 34 is a threaded through hole, for example, two second fixed holes 34 can be provided on the second fixed block 33 and located at the central symmetric position of the second fixed block 33. In addition, the second cable slot 35 is a high-voltage cable placement space, which penetrates the inside of the second handle 31 and the second main body 32.

[0068] As shown, Figure 10 The tool main body 41 of the double-diameter cutter 130 is a sheet-shaped cuboid, and the transverse dimension is consistent with the length of the first fixed block 23 of the left pressing piece 110. Among them, the transverse direction of the tool main body 41 and the length direction of the first fixed block 23 of the left pressing piece 110 are both corresponding to the length direction of the first cable slot 25 (that is, the cable length direction corresponding to the placement of the high-voltage cable 3 in the slot).

[0069] The thick wire diameter ring cutter 42, the thick wire diameter straight cutter 43, the thin wire diameter ring cutter 44, and the thin wire diameter straight cutter 45 are located at the bottom of the tool main body 41 of the double-diameter cutter 130. A third fixed hole 46 is vertically opened on the tool main body 41, and the number and position of the third fixed hole 46 are matched with those of the first fixed hole 24 and the second fixed hole 34, so that the threaded connecting piece for fixed installation can be installed in the first fixed hole 24, the second fixed hole 34 and the third fixed hole 46 to fix the left pressing piece 110, the double-diameter cutter 130 and the right pressing piece 120.

[0070] The third fixed hole 46 is a flat key-shaped through hole, which is located on the upper part of the tool main body 41 of the double-diameter cutter 130, and its transverse position, size and diameter are consistent with those of the fixed hole 24 of the left pressing piece 110, and its vertical size is slightly larger than the diameter of the fixed hole 24 of the left pressing piece 110.

[0071] The thick wire diameter ring cutter 42, the thick wire diameter straight cutter 43, the thin wire diameter ring cutter 44, and the thin wire diameter straight cutter 45 are located in the space composed of the cable slot 25 of the left pressing piece 110 and the cable slot 35 of the right pressing piece 120, which is not exposed during use to ensure the safety of the operator. The thick wire diameter ring cutter 42 and the thick wire diameter straight cutter 43 form a cutter group for stripping the first wire diameter, and the thin wire diameter ring cutter 44 and the thin wire diameter straight cutter 45 form a cutter group for stripping the second wire diameter.

[0072] The diameter of the thick wire diameter ring cutter 42 and the depth and length of the thick wire diameter straight cutter 43 are determined according to the size of the first wire diameter required, the diameter of the thick wire diameter ring cutter 42 determines the size of the stripped wire diameter, and the thick wire diameter straight cutter 43 determines the length of the wire diameter.

[0073] The diameter of the thin-diameter ring cutter 44 determines the stripped wire diameter, and the length of the thin-diameter straight cutter 45 determines the length of the wire diameter.

[0074] The thick-diameter ring cutter 42 and the thick-diameter straight cutter 43 cooperate to strip the first wire diameter, and the thin-diameter ring cutter 44 and the thin-diameter straight cutter 45 cooperate to strip the second wire diameter, so that the two wire diameters can be stripped simultaneously, improving work efficiency.

[0075] In addition, as an example, the thin-diameter straight cutter 45 is sequentially connected with the thin-diameter ring cutter 44, the thick-diameter straight cutter 43, and the thick-diameter ring cutter 42 in the direction of the first handle or the second handle.

[0076] As an example, the diameter of the thick-diameter ring cutter 42 is larger than that of the thin-diameter ring cutter 44.

[0077] As an example, the depth of the thick-diameter straight cutter 43 is smaller than that of the thin-diameter straight cutter 45.

[0078] As shown in Figure 11 Fig. 1 is a schematic diagram of the use of the pressing type stepped wire stripping tool for the high-voltage cable joint of the present application. When in use, the left pressing piece 110, the double-diameter cutter 130, and the right pressing piece 120 are tightly connected by sequentially passing bolts through the fixing hole 24 of the left pressing piece 110, the fixing hole 46 of the double-diameter cutter 130, and the fixing hole 34 of the right pressing piece 120. The combination of the upper pressing piece 1 is completed. The double-diameter cutter 130 can be adjusted in the vertical direction to control the sizes of the first wire diameter and the second wire diameter, realizing the adjustment and switching between different wire diameter requirements. The combination of the lower pressing piece assembly 2 is the same as that of the upper pressing piece assembly 1.

[0079] Then, the high-voltage cable 3 to be stripped is placed between the upper pressing piece assembly 10 and the lower pressing piece assembly 20, and one end of the high-voltage cable 3 is aligned with the head of the main body 22 of the left pressing piece 110. The main body 12 of the upper pressing piece assembly 1 and the lower pressing piece assembly 2 is pressed by a bench clamp to complete the stripping of the high-voltage cable, as shown in Figure 5 Fig. 2, so that the stepped shape of the two wire diameters of the high-voltage cable is formed at one time.

[0080] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the same. Although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacements for some of the technical features, without departing from the spirit and scope of the technical solutions of the embodiments of the present application.
