Description

Technical Field

[0001] The utility model belongs to the technical field of insulated wires, in particular to a soft film-wrapped insulated wire. Background Art

[0002] Soft film-wrapped insulated wire is a wire with special structure and performance, mainly used for connection between electrical equipment and instrument lines;

[0003] The soft film-wrapped insulated wire can be used for a long time within the specified temperature range, and has excellent properties such as resistance to high and low temperatures, oil, wear, acid and alkali, various chemical reagents, aging resistance, and non-combustion. It can be used safely in extremely harsh environments, and is particularly suitable for installation in instruments and electronic equipment with limited space and sensitive to weight;

[0004] In order to ensure the structural strength of the existing soft film-wrapped insulated wires, most of the wires have a solid structure inside. When the outside of the wire is squeezed, since there is no buffer space inside, the pressure will be directly applied to the conductor inside the wire, which is easy to cause deformation or even breakage of the conductor, affecting the service life of the wire;

[0005] In order to solve the above problems, the present application proposes a soft film-wrapped insulated wire. Utility Model Content

[0006] The utility model aims to provide a soft film-wrapped insulated wire, which solves the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model discloses a soft film-wrapped insulated wire, comprising a buffer strip, a bracket sleeved on the outside of the buffer strip, the buffer strip supported in the bracket, and a buffer space formed by the two, the outside of the bracket is connected to an insulated wire distributed circumferentially, the outside of the bracket is also connected to a support strip, the support strip is also located outside the insulated wire, the support strip is a plurality of circumferentially distributed strips, and the outside of the plurality of support strips after combination forms a complete circle, the outside of the support strip is coated with a heat insulation layer, the outside of the heat insulation layer is wrapped with an insulating film layer, and the outside of the insulating film layer is coated with a wear-resistant layer.

[0009] Furthermore, the buffer bar has a polygonal cross-section, the buffer bar has the same number of facades as the bracket, and is spaced apart from the bracket, and a first buffer groove is formed inside the buffer bar and penetrated by a cylinder.

[0010] Furthermore, the bracket includes a first arc-shaped groove formed on the outside and a buffer cavity formed through the inside of the bracket.

[0011] Furthermore, the insulated wire is fitted in the first arc-shaped groove, and the interior of the buffer cavity is tangent to the outer opposite surface of the buffer strip.

[0012] Furthermore, a second arc-shaped groove is formed on the inner side of the support bar, and the support bar is supported between two insulated wires through the second arc-shaped groove, and the second arc-shaped groove is in contact with and supported on the outside of the insulated wires.

[0013] Furthermore, a V-shaped buffer sheet spaced apart from the first arc-shaped groove is formed on the outside of the bracket, a buffer platform is integrally formed on the inner side of the support bar, and a second buffer groove is opened in the middle of the buffer platform.

[0014] Furthermore, a buffer space is formed between the bracket and the support bar, and the V-shaped buffer sheet contacts the outer side of the buffer platform and forms a buffering state.

[0015] The utility model has the following beneficial effects:

[0016] The utility model provides a cavity inside the bracket. When the position facing the insulated wire is under pressure, the cavity of the bracket and the buffer strip can play a buffering role. When the position between the two insulated wires outside the wire is under pressure, buffering is achieved through the gap between the bracket and the support strip and the buffer structure, thereby achieving buffering outside the entire wire.

[0017] The utility model can be well matched with the position distribution of the insulated wire by arranging the buffer structures distributed inside and outside, and can play a good buffering effect while controlling the diameter of the wire.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] See also Figure 1-6 As shown, the utility model is a soft film-wrapped insulated wire, including a buffer strip 1, a bracket 2 is sleeved on the outside of the buffer strip 1, the buffer strip 1 is supported in the bracket 2, and the two form a buffer space, the outside of the bracket 2 is connected to an insulated wire 3 distributed circumferentially, the outside of the bracket 2 is also connected to a support strip 4, the support strip 4 is also located outside the insulated wire 3, there are multiple support strips 4 distributed circumferentially, and the outside of the multiple support strips 4 after combination forms a complete circle, the outside of the support strip 4 is coated with a heat insulation layer 5, the outside of the heat insulation layer 5 is wrapped with an insulating film layer 6, and the outside of the insulating film layer 6 is coated with a wear-resistant layer 7.

[0031] The buffer strip 1 has a polygonal cross section, and the number of the outer facades of the buffer strip 1 is the same as that of the bracket 2, and the buffer strip 1 is spaced apart from the bracket 2. A first buffer groove 11 is formed inside the buffer strip 1. Figure 3 As shown, the contact surface between the outside of the buffer strip 1 and the inner side of the bracket 2 can play a buffering effect after being compressed. The buffer strip 1 can also play a buffering effect alone through the first buffer groove 11 after being compressed, forming multiple buffers while ensuring the structural strength of the wires, thereby better protecting the wires from working stably.

[0032] Among them, the bracket 2 includes a first arc-shaped groove 21 formed on the outside and a buffer cavity 22 formed through the inside of the bracket 2. In this embodiment, the first arc-shaped groove 21 can play a positioning role when the insulated wire 3 is installed, thereby improving the stability of the insulated wire 3 in the wire. The buffer cavity 22 forms a deformable buffer space on the outside of the wire, thereby avoiding excessive extrusion of the insulated wire 3 by external force and reducing the risk of deformation and breakage.

[0033] Among them, the insulated wire 3 is fitted in the first arc groove 21, and the interior of the buffer cavity 22 is tangent to the outer opposite surface of the buffer strip 1. In this embodiment, the tangent setting can not only ensure the stable connection between the buffer strip 1 and the bracket 2, but also form a buffer between the two.

[0034] Among them, a second arc groove 41 is formed on the inner side of the support bar 4, and the support bar 4 is supported between the two insulated wires 3 through the second arc groove 41. The second arc groove 41 is supported by the outer part of the insulated wire 3. In this embodiment, there are two symmetrical second arc grooves 41 on the inner side of the support bar 4, which support the two adjacent brackets 2 respectively, which not only ensures the supporting effect between the two brackets 2, but also forms a buffer between the support bar 4 and the bracket 2.

[0035] Among them, the outside of the bracket 2 is also formed with a V-shaped buffer sheet 23 spaced apart from the first arc groove 21, the inner side of the support bar 4 is integrally formed with a buffer platform 42, and a second buffer groove 43 is opened in the middle of the buffer platform 42. In this embodiment, the V-shaped buffer sheet 23 and the second buffer groove 43 are in contact with each other and are in a preparatory buffer state, which will not affect the structural strength of the wire, and can also play a buffering role immediately after being compressed, thereby ensuring the reliable use of the wire.

[0036] Among them, a buffer space is formed between the bracket 2 and the support bar 4, and the V-shaped buffer sheet 23 and the outer side of the buffer platform 42 are in contact with each other and form a buffering state. In this embodiment, when the outside of the wire is pressurized, the V-shaped buffer sheet 23 and the buffer platform 42 will squeeze each other. At this time, the outside of the V-shaped buffer sheet 23 expands outward, and the buffer platform 42 is pressed inward. The second buffer groove 43 is deformed and buffers the pressure, and the deformation of the V-shaped buffer sheet 23 also buffers the pressure.

[0037] It is understandable that by providing internal and external buffer structures, buffering can be performed according to the different pressure positions of the wires, and the buffer structures and the positions of the insulated conductors 3 are reasonably distributed, thereby ensuring the buffering effect while controlling the overall diameter of the wires.

[0038] A specific application of this embodiment is: the buffer strip 1 and the bracket 2 are extruded, an insulated wire 3 is connected to the outside of the bracket 2, a support strip 4 is connected between two brackets 2, a heat insulation layer 5 is coated on the outside of the support strip 4, an insulating film layer 6 is wrapped around the outside of the insulating layer 5, and a wear-resistant layer 7 is coated on the outside of the insulating film layer 6;

[0039] like Figure 3 As shown, the buffer strip 1 is located at the center of the buffer cavity 22 inside the bracket 2 , and a buffer space is left between the bracket 2 and the support strip 4 .
