[0040] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0041] It should be noted that if the embodiments of the utility model involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0042] In addition, if the embodiments of the utility model involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one feature. In addition, if "and / or", "and / or" or "and / or" appear in the whole text, the meaning includes three parallel schemes, for example, "A and / or B" includes A scheme, or B scheme, or A and B simultaneously satisfy the scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0043] The commonly used side-by-side wire is produced by connecting multiple wires together, but the wire harness used in the production process of electronic products needs to be separated into different wire harnesses according to actual conditions. In the related art, the wire is separated by manually peeling it with fingers or cutting it with scissors and then peeling it. This wire separation method is time-consuming and labor-intensive, and the edges of the separated wire sheath have burrs, poor quality, and other defects.

[0044] The applicant found in the early stage that the wire can be cut by using a special cutting device. The cutting device can include a support body and a blade. The support body supports (or transports) the wire. When the wire passes through the blade, the wire can be cut by relative movement of the two. However, this setting often has poor flexibility, and the cutting device is difficult to adapt to wires of different specifications or different cutting modes.

[0045] In view of this, referring to Figures 1-10 The embodiment of the utility model provides a wire separating device 100 for cutting the wire 200. The wire 200 can be any wire that needs to be cut, such as cutting during the production stage of the wire 200 for subsequent operation or during the use stage of the wire 200. Therefore, the wire 200 can be a side-by-side wire. When not cut, the wire 200 is in a state of multiple bundles of side-by-side connection. The wire separating device 100 can cut the multiple bundles of wire 200 into single bundles of wire 200 or into multiple bundles of wire 200 with fewer numbers (for example, cutting 7 bundles of side-by-side connection into a combination of 2+3+2). For ease of description, the wire separating device 100 is applied to the above-mentioned side-by-side wire as an illustration.

[0046] The wire separating device 100 includes a base 110 and a cutting assembly 120. Specifically, referring to Figures 1-4The base 110 is adapted to place the wire 200. In some embodiments, the base 110 can only provide a supporting force to the wire 200, so as to make the wire dividing device 100 more compact, and facilitate to reduce the cost, and the wire 200 can be driven to move by manual or other devices. In other embodiments, the base 110 can transport the wire 200, so as to improve the automation degree of the wire dividing device 100. The cutting assembly 120 is detachably connected to the base 110, and the cutting assembly 120 comprises a cutting piece 121. The cutting piece 121 is used to divide the wire 200, and therefore, the cutting piece 121 can be in any suitable structural shape according to the requirement, which is not limited here. The cutting assembly 120 further defines a guide groove 122 extending along the length direction X, and the guide groove 122 is adapted to accommodate the wire 200. The cutting piece 121 faces the guide groove 122 along the length direction X, so that the cutting piece 121 is adapted to divide the wire 200 along the length direction X. By arranging the guide groove 122 and facing the cutting piece 121 (in particular, the cutting edge of the cutting piece 121) towards the guide groove 122, the wire 200 can be guided by the guide groove 122 and move relative to the cutting piece 121, so as to achieve the division of the wire 200. Therefore, in particular, since the cutting piece 121 and the guide groove 122 are both arranged on the detachable cutting assembly 120, when the wire 200 or the cutting requirement changes, the parameters related to the wire 200 (such as the size and arrangement form of the cutting piece 121, and the size and shape of the guide groove 122, etc.) can be changed by replacing the cutting assembly 120 to achieve the adaptation, so that the wire dividing device 100 of the utility model is convenient to adapt to different specifications of the wire 200 and different cutting modes.

[0047] It can be seen that the wire separating device 100 of the utility model includes a base 110 and a cutting assembly 120. The base 110 is suitable for placing the wire 200. The cutting assembly 120 is detachably connected to the base 110, and the cutting assembly 120 includes a cutting piece 121 and defines a guide groove 122 extending along the length direction X, which is suitable for accommodating the wire 200. The cutting piece 121 faces the guide groove 122 along the length direction X, so that the cutting piece 121 is suitable for separating the wire 200 along the length direction X. Compared with the related art, the wire separating device 100 of the utility model can separate the wire 200 by extending the wire 200 into the guide groove 122 and moving the wire 200 relative to the cutting piece 121, which has the advantages of low cost, simple structure, convenient operation, small size, low requirement on use scene, no need for electrical configuration, and the like, and the wire separating edge has no burr, and the effect is better. In addition, since the cutting piece 121 and the guide groove 122 are arranged on the detachable cutting assembly 120, when the wire 200 or the cutting requirement changes, the cutting assembly 120 can be replaced to change the parameters related to the wire 200 to adapt to different specifications of the wire 200 and different cutting modes, so that the wire separating device 100 of the utility model is convenient to adapt to different specifications of the wire 200 and different cutting modes. Therefore, the wire separating device 100 of the utility model is convenient to operate, efficient in cutting, and has strong adaptability to the wire 200.

[0048] In order to make the structure of the wire separating device 100 more compact, referring to Figures 1-5 and Figures 8-9 In some embodiments, the cutting assembly 120 further includes a mounting block 123, the mounting block 123 defines the guide groove 122 and a receiving groove 124, and the cutting piece 121 is located in the receiving groove 124. It can be understood that the mounting block 123 can define the guide groove 122 on one hand and the receiving groove 124 for accommodating the cutting piece 121 on the other hand, so that the overall structure of the cutting assembly 120 is more compact, which is beneficial to saving the arrangement space. The cutting piece 121 can be directly connected with the mounting block 123 or can be connected with other structures and extended into the receiving groove 124. The connection mode of the cutting piece 121 can be detachable connection or non-detachable connection.

[0049] When the cutting piece 121 is detachably connected to the mounting block 123, in order to more stably install the cutting piece 121, referring to Figures 1-5 , Figure 7 and Figure 10In some embodiments, the cutting assembly 120 further comprises a connecting block 125 detachably connected with the mounting block 123, the connecting block 125 is configured to be capable of limiting the displacement of the cutting member 121. It can be understood that, in the process of assembling the cutting member 121, the cutting member 121 can be first extended into the accommodating groove 124, and then the connecting block 125 is assembled in the mounting block 123, at this time, since the connecting block 125 is capable of limiting the displacement of the cutting member 121, the stable installation of the cutting member 121 is realized; when the cutting member 121 needs to be disassembled, the connecting block 125 is first disassembled from the mounting block 123, and then the cutting member 121 is taken out from the accommodating groove 124.

[0050] Based on the above-mentioned connecting block 125, referring to Figure 4 、 Figure 6 and Figure 10 In some embodiments, the connecting block 125 has an avoiding hole 1251 extending along the height direction Z perpendicular to the length direction X, and the cutting member 121 is at least partially located in the avoiding hole 1251. It can be understood that, when the cutting member 121 is extended into the accommodating groove 124, a part of the cutting member 121 is exposed from the accommodating groove 124, and the exposed part extends into the avoiding hole 1251, so that the hole wall of the avoiding hole 1251 can abut against the cutting member 121, thereby realizing the limiting effect of the cutting member 121. More specifically, in some embodiments, the accommodating groove 124 extends along the length direction X, so that the cutting member 121 can extend into the accommodating groove 124 along the length direction X, and the edge of the avoiding hole 1251 in the projection plane perpendicular to the height direction Z is at least partially overlapped with the edge of the accommodating groove 124 in the projection plane, thereby realizing the limiting effect of the cutting member 121 along the length direction X. In addition, the part of the cutting member 121 extending into the avoiding hole 1251 can also facilitate the design of the size of the cutting member 121 along the height direction Z. Specifically, when it is ensured that the size of the cutting member 121 along the height direction Z is long enough, it can be ensured that the cutting member 121 can cut the corresponding position of the wire 200 and play the best cutting effect, but if the cutting member 121 is too long, if the upper side of the cutting member 121 is closed (i.e. the connecting block 125 blocks the cutting member 121), it is easy to cause interference and the cutting member 121 cannot be installed. Therefore, by setting the avoiding hole 1251, the above-mentioned problem can be solved, so that when the height of the cutting member 121 is greater than the lower end of the connecting block 125, the installation can still be formed by extending into the avoiding hole 1251, which ensures the length of the cutting member 121 and realizes the stable installation effect of the cutting member 121.

[0051] In order to make full use of the space of the mounting block 123, referring to Figure 9In some embodiments, the guide groove 122 can extend along the length direction X, and the side of the accommodation groove 124 can be connected to the groove bottom surface of the guide groove 122. The above arrangement can make the overall structure of the mounting block 123 compact, and can make the accommodation groove 124 connected to the guide groove 122, so that the cutting member 121 can directly act on the wire 200 in the guide groove 122, and the cut wire 200 can still be located in the guide groove 122, thereby making the guiding effect better.

[0052] Referring to Figure 1 and Figure 6 In some embodiments, the base 110 defines a mounting groove 111, and the cutting assembly 120 is located in the mounting groove 111. Along the length direction X, one side of the base 110 is an extension side 112, and the mounting groove 111 and the accommodation groove 124 are both connected to the extension side 112. It can be understood that the mounting groove 111 is used to mount the cutting assembly 120. Specifically, after the cutting assembly 120 is placed in the mounting groove 111, it can be fixed by screw connection. In addition, the extension side 112 can be the side through which the wire 200 extends after being cut. Therefore, the arrangement that the mounting groove 111 and the accommodation groove 124 are both connected to the extension side 112 can make the user conveniently perform various operations, such as mounting the cutting assembly 120, mounting the cutting member 121, and taking the wire 200, at the extension side 112, so that the layout of the wire dividing device 100 is more reasonable.

[0053] In order to further fix the cutting member 121, referring to Figure 1 and Figure 7 In some embodiments, the cutting assembly 120 further includes a fastening screw 126, and the mounting block 123 has a fastening threaded hole 1231 extending along the width direction Y perpendicular to the length direction X. The fastening screw 126 is matched with the fastening threaded hole 1231 and abuts against the cutting member 121 along the width direction Y. By abutting against the cutting member 121 along the width direction Y, one side of the cutting member 121 can be abutted against by the fastening screw 126, and the other side can be abutted against by the groove surface of the accommodation groove 124, thereby realizing the positioning of the cutting member 121 along the width direction Y. Based on the abutting effect of the fastening screw 126 on the cutting member 121 along the width direction Y, and in combination with the foregoing embodiment of the avoiding hole 1251, the avoiding hole 1251 can further limit the displacement of the cutting member 121 along the length direction X.

[0054] Based on the foregoing embodiment of the connecting block 125, in order to make the cutting effect of the wire 200 better, referring to Figure 10In some embodiments, the connecting block 125 comprises a protrusion 1252 which protrudes into the guide slot 122 along the height direction Z which is perpendicular to the length direction X. It can be understood that the protrusion 1252 can reduce the exposed area of the guide slot 122 along the height direction Z, so that when the wire 200 is inserted into the guide slot 122, it can move along the length direction X to the position where the protrusion 1252 is arranged, at this time, due to the reduced size of the exposed guide slot 122, the wire 200 can be further squeezed and limited, so that the wire 200 around the cutting member 121 can be prevented from shaking to some extent, so that the cutting effect is improved.

[0055] For the specific design of the accommodating slot 124, see Figures 8-9 In some embodiments, the accommodating slot 124 can be a rectangular slot to fit the rectangular strip-shaped wire 200, and the side wall of the accommodating slot 124 can have two parts connected to each other, the side wall close to the bottom surface of the slot extends along the height direction Z, and the side wall away from the bottom surface of the slot extends along the width direction Y and the height direction Z in a diagonal direction, so that the opening direction of the guide slot 122 is towards the outside. The above arrangement can make the wire 200 more easily inserted into the guide slot 122. In addition, in order to better fit the wire 200, in some embodiments, along the height direction Z, the size of the accommodating slot 124 is d1, and the size of the wire 200 is d2, and it satisfies: d2-0.05mm≤d1≤d2+0.05mm, wherein d1 is defined as the height of the side wall which can face the wire 200 along the width direction Y; in other embodiments, along the width direction Y, the size of the accommodating slot 124 is d3, and the size of the wire 200 is d3, and it satisfies: d4-0.05mm≤d3≤d4+0.05mm.

[0056] In order to further increase the adaptability of the wire dividing device 100, see Figure 2 In some embodiments, the number of cutting members 121 is multiple, and they are arranged at intervals along the width direction Y which is perpendicular to the length direction X. Through the above arrangement, the user can configure the number of cutting members 121 and the arrangement form of the cutting members 121 according to the needs. For example, see Figure 2 In some embodiments, the number of cutting members 121 is two, and at this time, the two cutting members 121 can jointly cut the 7 wires 200 connected side by side into a wire 200 with a connection combination of 2+3+2. The user can replace the specifications of the cutting assembly 120, or the specifications of the cutting members 121, or the assembly form of the cutting members 121 to adapt to different needs.

[0057] In order to facilitate the transportation of the wire 200, see Figure 1 or Figure 5In some embodiments, the side of the base 110 facing the wire 200 has a first surface 113 extending along the length direction X and adapted to support the wire 200, and a second surface 114 on both sides of the first surface 113. It can be understood that the first surface 113 serves as a carrier for the wire 200, i.e. the wire 200 can move on the first surface 113, and the power source for the movement of the wire 200 can be provided by the first surface 113 or by other devices or manually, and the second surface 114 is the part of the side of the base 110 not in contact with the wire 200. Based on this, in some embodiments, the dynamic friction coefficient of the first surface 113 is smaller than that of the second surface 114. Thus, the friction force experienced by the wire 200 during movement on the first surface 113 can be reduced, thereby facilitating the transportation of the wire 200 and making the pushing of the wire more smooth. In some embodiments, the static friction coefficient of the first surface 113 is smaller than that of the second surface 114. It should be noted that in some embodiments, the first surface 113 and the second surface 114 can both be part of the main body of the base 110; in other embodiments, the first surface 113 or the second surface 114 can be an additional surface attached to the main body of the base 110. In addition, in other embodiments, the first surface 113 and the second surface 114 can have other relative position settings, or the side of the base 110 facing the wire 200 can be entirely made of a material with a small dynamic friction coefficient, such as polytetrafluoroethylene material.

[0058] To achieve a better friction-reducing effect of the first surface 113, in some embodiments, the material of the first surface 113 is polytetrafluoroethylene (PTFE), which can also be referred to as Teflon. The friction coefficient of polytetrafluoroethylene is extremely low, with a dynamic friction coefficient of only about 0.04, so it can effectively reduce the friction and wear between components, and improve the service life and pushing efficiency of the wire separating device 100 and the wire 200.

[0059] The above is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation based on the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
