Wire crimping pipe protector

Abstract

The utility model discloses a wire crimping tube protector, which comprises two protection half tubes, and the two protection half tubes are suitable for being attached to each other to form a tubular protection tube. The crimping position between the two sections of wires is suitable for being coated by a protection tube; the mutually attached end faces of the two protection half pipes are connected through a clamping structure in the circumferential direction. The beneficial effects of the utility model are that the clamping structure is arranged in the circumferential direction of the two protection half tubes for connection, so that when the protection tube is subjected to bending force, the clamping structure enables the two protection half tubes to be uniformly stressed, and then the expansion of the protection half tubes when the protection half tubes are bent can be limited, thereby achieving the protection of the crimping position of the wire. Meanwhile, the clamping structure can generate friction force in the circumferential direction of the protection tube to limit the mutual separation of the protection half tubes, so that the protection of the protection tube on the wire crimping position can be further improved.

Description

Technical Field

[0001] The present application relates to the field of power electronics technology, and particularly relates to a wire crimping tube protector. Background Art

[0002] A wire is a commonly used power transmission unit in power facilities. When performing long-distance power transmission, multiple wires often need to be crimped using a crimping tube. When the wires leave the factory, the crimped multiple wires often need to be wound and packaged. However, when the wires are wound, since the wires need to be bent, the crimping tube of the wire may become loose due to the bending, and further, poor contact of the wire may occur. Therefore, when the wires are wound and packaged, in order to ensure good crimping of the wires, the crimping position of the wires needs to be protected by a protector.

[0003] A common protector is a tubular protection tube formed by splicing two semi-circular tubes to wrap and protect the crimping position of two wires. However, when the existing protector is used, since the protection tube will also bend to a certain extent under a large force, the two semi-circular tubes of the protection tube will bend and separate from each other in the middle of the splicing position, resulting in the failure of the protection of the wire. Based on this, there is an urgent need to improve the existing wire protector. Utility Model Content

[0027] Next, in combination with the detailed implementation manners, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0028] In the description of the present application, it should be noted that for orientation terms, such as terms "center", "horizontal", "vertical", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the indicated orientation and position relationship are based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0029] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence.

[0030] The terms "include" and "have" in the description and claims of the present application, and any of their variations, are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0031] In one preferred embodiment of the present application, as Figure 1 and Figure 2 shown, a wire crimping tube protector includes two protective half-tubes 11 with semi-circular cross-sections. The two protective half-tubes 11 can be formed into a tubular protective tube 1 by fitting together. When transporting the wire, the crimping position between two sections of wire 200 can be covered by the protective tube 1 through the fitting together of the two protective half-tubes 11. And when the two protective half-tubes 11 are fitted together to form the protective tube 1, the end faces where the two protective half-tubes 11 are fitted together are connected by a circumferential engaging structure 13. Furthermore, through the restriction of the engaging structure 13, the expansion tendency generated when the protective tube 1 is bent is restricted, thereby effectively protecting the crimping position of the wire 200.

[0032] It should be known that when the wire 200 is wound, the wire 200 can be transported to the position of the winding mechanism through a transporting device. Specifically, the specific structure and working principle of the transporting device are well-known technologies to those skilled in the art. A common transporting device transports the wire 200 placed on the roller 300 through the rotation of the roller 300. The specific structure and working principle of the winding mechanism are well-known technologies to those skilled in the art, so they will not be elaborated in detail here.

[0033] It can be understood that when the protective tube 1 is transported to the winding mechanism, if the end faces of the two protective half-tubes 11 are tangent to the winding direction of the wire 200, the force exerted on the protective tube 1 by the wire 200 through winding can be equivalent to a bending force perpendicular to the end face of the protective half-tube 11. At this time, this bending force will drive the end faces of the two protective half-tubes 11 to fit and hold tightly together. However, the above situation is very rarely encountered during the winding of the wire 200. In most cases, the bending force exerted on the protective tube 1 by the wire 200 through winding is inclined to the end face of the protective half-tube 11. Then, at this time, the bending force can be decomposed into a first component force perpendicular to the end face of the protective half-tube 11 and a second component force along the circumferential direction. The first component force will drive the protective tube 1 to bend, and the second component force will drive the two protective half-tubes 11 to move away from each other. This will cause the two protective half-tubes 11 forming the protective tube 1 to expand away from each other while bending, and further cause the protection of the crimping position of the wire 200 by the protective tube 1 to fail. And according to the different inclination angles between the bending force and the end face of the protective half-tube 11, the magnitudes of the first component forces received by the two protective half-tubes 11 are also different, which can further exacerbate the expansion of the two protective half-tubes 11.

[0034] In this embodiment, the two protective half-tubes 11 are connected by providing a circumferential engaging structure 13 on the end faces that are in mutual contact. The engagement of the two protective half-tubes 11 can generate a restraining force on the protective tube 1 in the axial direction. Specifically, the restraining force formed by the engaging structure 13 can keep the first component forces received by the two protective half-tubes 11 always uniform and stable, and further make the bending of the two protective half-tubes 11 tend to be consistent to limit the expansion tendency of the protective half-tubes 11 during the bending process, thereby improving the protection of the protective tube 1 for the crimping position of the wire 200. At the same time, this restraining force can provide a normal pressure for the frictional force formed by the engaging structure 13 in the circumferential direction during the bending process of the protective tube 1, which can further ensure the mutual contact of the two protective half-tubes 11 during the bending process, so as to further limit the expansion tendency of the protective half-tubes 11 during the bending process, thereby further improving the protection of the protective tube 1 for the crimping position of the wire 200.

[0035] In this embodiment, there are various specific structures of the engaging structure 13. For the convenience of understanding, the following will be described in detail through two specific examples.

[0036] Example 1: As Figure 3 shown, the engaging structure 13 includes a protruding portion 131 and a recessed portion 132. The protruding portion 131 and the recessed portion 132 are respectively provided on the two protective half-tubes 11; the protruding portion 131 protrudes from the end face of the protective half-tube 11 in the circumferential direction, and the recessed portion 132 is recessed from the end face of the protective half-tube 11 in the circumferential direction. The mutual engagement of the protruding portion 131 and the recessed portion 132 is used to achieve the mutual contact of the two protective half-tubes 11 of the protective tube 1 during the bending process.

[0037] Example 2: The engaging structure 13 includes a first protruding portion and two second protruding portions; the first protruding portion is provided on the end face of one of the protective half-tubes 11, and the two second protruding portions are arranged at intervals on the end face of the other protective half-tube 11 so that a recessed groove corresponding to the size of the first protruding portion is formed between the two second protruding portions; and then when the two protective half-tubes 11 are in mutual contact, the first protruding portion can be engaged with the recessed groove to achieve the structural stability of the protective tube 1 during the bending process.

[0038] It should be noted that the above two examples can both meet the requirements of this application. However, for the above Example 1, the required two protective half-tubes 11 and the corresponding protruding portion 131 and recessed portion 132 can be directly obtained by cutting a tubular blank through laser cutting or wire cutting. For the above Example 2, the first protruding portion and the second protruding portions need to be welded additionally. Therefore, in this embodiment, the engaging structure 13 preferably adopts the above Example 1, and the following content will also be described in detail taking Example 1 as an example.

[0039] It can be understood that the thickness of the protruding portion 131 and the recessed portion 132 in the radial direction of the protection tube 1 may be equal to the thickness of the protection half-tube 11, or may be thinner than the thickness of the protection half-tube 11; however, for the convenience of processing, in this embodiment, it is preferably that both the protruding portion 131 and the recessed portion 132 have the same thickness as the protection half-tube 11, and thus can be directly processed by laser cutting or wire cutting.

[0040] In this embodiment, as Figure 3 and Figure 4 shown, both end faces of a single protection half-tube 11 are cooperated with the corresponding end faces of another protection half-tube 11 through the engaging structure 13. Thus, when the protection tube 1 is bent in any direction, both protection half-tubes 11 can ensure the structural stability of the protection tube 1 through the engaging structure 13.

[0041] It should be known that the protection half-tube 11 has two end faces, which are respectively located on both sides of the protection half-tube 11 along the circumferential direction. For the setting of the engaging structure 13, it can be set on one of the end faces of the protection half-tube 11. Thus, when the protection tube 1 is bent, if the position of the engaging structure 13 is higher than the midpoint height of the protection tube 1 along the direction away from the bending direction, the engaging structure 13 can play a good role in stabilizing the structure of the protection tube 1; while for the protection tube 1 in other cases, the stabilizing structure effect of the engaging structure 13 is limited; therefore, in this embodiment, both end faces of the protection half-tube 11 can be connected through the engaging structure 13. Thus, when the protection tube 1 is bent at any position, there is always a position of an engaging structure 13 that is higher than the midpoint height of the protection tube 1 along the direction away from the bending direction, and thus the structural stability of the protection tube 1 can be effectively ensured.

[0042] In this embodiment, the single end face of the protection half-tube 11 and the corresponding end face of another protection half-tube 11 can be cooperatively connected through one engaging structure 13, or can be connected through multiple engaging structures 13. Based on the setting manner of the engaging structure 13, there are three specific setting manners for the two protection half-tubes 11 to be mutually attached through the engaging structure 13 to form the protection tube 1. The following will elaborate on the three setting manners.

[0043] Setting manner one: Both end faces of the protection half-tube 11 are engaged and connected with the corresponding ends of another protection half-tube 11 through one engaging structure 13. For the setting of these two engaging structures 13, they can be commonly set in the middle of the protection tube 1; or can be respectively set at both ends of the protection tube 1.

[0044] In the second setting method, the first end face of the protective half pipe 11 and the corresponding end face of another protective half pipe 11 are connected by a clamping structure 13, and this clamping structure 13 can be represented by the clamping structure #1. The second end face of the protective half pipe 11 and the corresponding end of another protective half pipe 11 are connected by a plurality of clamping structures in cooperation, and this clamping structure 13 can be represented by the clamping structure #2.

[0045] It should be noted that, in order to ensure the stable force of the protective pipe 1, the clamping structure #1 can be arranged at the middle position of the protective half pipe 11 along the axial direction, and a plurality of clamping structures #2 are arranged at equal intervals along the axial direction of the protective half pipe 11.

[0046] In the third setting method: both ends of the protective half pipe 11 are connected by a plurality of clamping structures 13 with the corresponding ends of another protective half pipe 11. A plurality of clamping structures 13 corresponding to each end face of the protective half pipe 11 are arranged at equal intervals along the axial direction of the protective half pipe 11.

[0047] It can be understood that the above three setting methods can all meet the requirements of this application. However, in order to ensure the most stable structure of the protective pipe 1 when it is bent, the setting method of the clamping structure 13 between the two protective half pipes 11 in this embodiment preferably adopts the above-mentioned third setting method. For the convenience of understanding, a specific example will be described in detail below.

[0048] Specifically, as Figure 2 and Figure 3 shown, both end faces of the protective half pipe 11 are connected by two clamping structures 13 arranged at intervals with the corresponding ends of another protective half pipe 11. The two clamping structures 13 on a single end face of the protective half pipe 11 can be symmetrically arranged along the midpoint of the axial direction of the protective half pipe 11.

[0049] In this embodiment, there are various specific setting methods for the plurality of clamping structures 13 corresponding to each end face of the protective half pipe 11. For the convenience of understanding, two specific examples will be described in detail below.

[0050] Specific Example 1: A convex portion 131 and a concave portion 132 are respectively arranged on a single end face of the protective half pipe 11; that is, at least one convex portion 131 and at least one concave portion 132 are arranged on a single end face of the protective half pipe 11; and convex portions 131 and concave portions 132 are respectively arranged at the positions of the clamping structures 13 corresponding to the two end faces of the protective half pipe 11. In one specific example, as Figure 3 shown, a convex portion 131 and a concave portion 132 are respectively arranged at both ends of each end face of the protective half pipe 11, and a convex portion 131 and a concave portion 132 are respectively arranged at the same end of the two end faces of the protective half pipe 11.

[0051] Specific Example 2: All of the single end faces of the protective half tube 11 are provided with convex portions 131 or concave portions 132, and convex portions 131 and concave portions 132 are respectively provided at the positions of the corresponding engaging structures 13 on the two end faces of the protective half tube 11.

[0052] It can be understood that the above two specific examples can both meet the requirements of this application; for the convenience of understanding, the following will take the above Specific Example 1 as an example for a detailed description. It should be known that the setting of the concave portion 132 will cause the circumferential dimension of the protective half tube 11 at this position to be shortened, making the setting position of the concave portion 132 a structurally weak position of the protective half tube 11; in order to improve the structural strength of the protective half tube 11 as much as possible, the positions of the two engaging structures 13 at the same end of the two end faces of the protective half tube 11 can be aligned, and convex portions 131 and concave portions 132 are respectively provided on the two end faces of the aligned two engaging structures 13 on the same protective half tube 11; thereby, the shortened circumferential dimension of the concave portion 132 can be compensated by the extended setting of the convex portion 131, so that the circumferential dimensions of the protective half tube 11 at any axial position are approximately equal, thereby improving the structural strength of the protective half tube 11.

[0053] In this embodiment, there are various specific structural settings for the convex portion 131 and the concave portion 132. For the convenience of understanding, the following will be described in detail through three specific structures.

[0054] Specific Structure 1: As Figure 5 shown, along the circumferential direction away from the end face of the protective half tube 11 for fitting, the widths of the convex portion 131 and the concave portion 132 remain equal along the extending direction; and along the circumferential direction, both sides of the convex portion 131 and the concave portion 132 are parallel to the radial plane of the protective tube 1. For the convenience of understanding, it can be said more specifically that the projections of the convex portion 131 and the concave portion 132 in the radial direction are rectangles. Thus, when the protective tube 1 is bent, the convex portion 131 and the concave portion 132 can provide a normal pressure through the deformation of the sides to form a frictional force in the circumferential direction, thereby ensuring the structural stability of the protective tube 1.

[0055] Specific Structure 2: As Figure 6As shown, along the circumferential direction away from the end face of the protective half-tube 11 for fitting, the widths of the convex portion 131 and the concave portion 132 are equal along the extending direction; and along the circumferential direction, both sides of the convex portion 131 and the concave portion 132 are inclined to the radial plane of the protective tube 1. More specifically, the projections of the convex portion 131 and the concave portion 132 in the radial direction are parallelograms. Thus, when the protective tube 1 is bent, the convex portion 131 and the concave portion 132 can not only provide a positive pressure through the deformation of the sides to counteract each other to form a frictional force in the circumferential direction, but also further limit the tendency of the protective half-tubes 11 to move away from each other through the limit cooperation of the convex portion 131 and the concave portion 132 in the circumferential direction, so as to further improve the structural stability of the protective tube 1.

[0056] Specific structure three: As Figure 7 As shown, along the circumferential direction away from the end face of the protective half-tube 11 for fitting, the widths of the convex portion 131 and the concave portion 132 gradually increase along the extending direction; and along the circumferential direction, both sides of the convex portion 131 and the concave portion 132 are inclined to the radial plane of the protective tube 1. More specifically, the projections of the convex portion 131 and the concave portion 132 in the radial direction are trapezoids. Thus, when the protective tube 1 is bent, the convex portion 131 and the concave portion 132 can not only provide a positive pressure through the deformation of the sides to counteract each other to form a frictional force in the circumferential direction, but also further limit the tendency of the protective half-tubes 11 to move away from each other through the limit cooperation of the convex portion 131 and the concave portion 132 in the circumferential direction, so as to further improve the structural stability of the protective tube 1.

[0057] In this embodiment, as Figures 4 to 7 As shown, the extending lengths of the convex portion 131 and the concave portion 132 along the circumferential direction are equal, both being L, and at the same time, the widths of the convex portion 131 and the concave portion 132 along the axial direction of the protective tube 1 are also equal, both being B. The specific values of the extending length L and the width B of the convex portion 131 and the concave portion 132 can be selected according to the actual needs of those skilled in the art.

[0058] It should be noted that the extension lengths of the protrusion 131 and the recess 132 should not be too long or too short. An extension length that is too short results in a short mating length between the protrusion 131 and the recess 132, and thus cannot provide a good limiting effect. Since the cross-sectional structure of the protective half-tube 11 at the engaging structure 13 is misaligned with the remaining cross-sectional structures, if the extension length of the recess 132 is set too long, the structural strength of the protective half-tube 11 will be greatly weakened. Therefore, in this embodiment, the extension length L of the protrusion 131 and the recess 132 in the circumferential direction can preferably be 0.5% to 10% of the circumferential length of the protective tube 1, and more preferably 1% to 5% of the circumferential length of the protective tube 1. Correspondingly, the widths B of the protrusion 131 and the recess 132 in the axial direction should not be too short or too long either. In this embodiment, the widths B of the protrusion 131 and the recess 132 in the axial direction can preferably be 0.2% to 10% of the axial length of the protective tube 1, and more preferably 0.5% to 5% of the axial length of the protective tube 1.

[0059] For the sake of easy understanding, the following can be illustrated by a specific example. Suppose the diameter of the protective tube 1 is 50 cm and the axial length is 500 cm; then the extension length L of the protrusion 131 and the recess 132 can be taken as 1.6 cm to 7.8 cm, and specifically L = 2 cm can be taken. At the same time, the widths B of the protrusion 131 and the recess 132 can be taken as 2.5 cm to 10 cm, and specifically B = 3 cm can be taken.

[0060] In this embodiment, as Figures 1 to 3 shown, grooves 110 are provided on the outer sides of both ends of the protective half-tube 11; when the two protective half-tubes 11 are fitted to each other, the grooves 110 on the two protective half-tubes 11 can be aligned with each other to form an integral circular groove, and then the two protective half-tubes 11 can be fitted and fastened along the grooves 110 by fasteners to form the protective tube 1. There are various fasteners for fastening the protective half-tube 11, and specifically, they can be selected according to the actual needs of those skilled in the art. Common fasteners include clamps and straps, etc.

[0061] In this embodiment, as Figures 1 to 3 shown, the protective tube 1 further includes protective sleeves 12 sleeved at both ends, and the wire 200 can pass through the flexible protective sleeves 12 to reduce the wear at the port position of the protective tube 1.

[0062] It should be noted that the half pipe 11 is generally made of metal, and the surface of the wire 200 is coated with an insulating layer; when the wire 200 is wound, the wire 200 will be bent at the port position of the protection pipe 1, so that the port of the protection pipe 1 forms a shear on the wire 200, which may cause the insulating layer on the surface of the wire 200 to be damaged, thus affecting the use safety of the wire 200. By sleeving flexible protective sleeves 12 at both ends of the protection pipe 1, direct contact between the wire 200 and the port of the protection pipe 1 can be avoided, thereby ensuring the integrity of the insulating layer on the surface of the wire 200 to ensure the use safety of the wire 200. The specific material of the protective sleeve 12 can be selected according to the actual needs of those skilled in the art, and common materials are rubber.

[0063] The above describes the basic principle, main features and advantages of the present application. Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed. The scope of protection required by the present application is defined by the appended claims and their equivalents.
