Description

Technical Field

[0001] The present disclosure relates to the technical field of cable assembly equipment, and in particular to a cable stretching buffer device. Background Art

[0002] During the swing test of hinge life and the opening and closing process, the hinge rotates and the corresponding cables will be stretched and retracted. If the cables are installed compactly, there is a certain risk of damage during the pulling process, affecting normal use. If the cables are stretched too tight, they will also scrape against the surrounding structure of the hinge, which may cause abnormal noise. In addition, if the cable is not installed long enough, the pulling and retraction of the cable will also affect the plugging stability of the connector at one end of the cable.

[0003] To address this problem, the commonly used solution is to set up additional cable management troughs or limiting structures to lay the cables relatively loosely, so that the cables have greater freedom of movement. However, this will also cause the cables to produce different degrees of pulling, stretching, and abnormal noise.

[0004] Therefore, there is an urgent need for a cable assembly device with a new structure on the market to solve the problems in the prior art of cables causing abnormal noises due to pulling and stretching during movable installation, and the problem that the length of the installed cable easily affects the stability of the plug connector.

[0018] The wire blocking member is arranged opposite to the notch of the wire accommodating arc groove, and the distance between the two is smaller than the diameter of the cable.

[0019] In one possible implementation manner, the wire blocking member comprises a connecting plate and a wire blocking plate vertically connected to each other in an L shape;

[0020] The connecting plate is vertically connected to the side outer peripheral wall of the rotating member, and the wire blocking plate is parallel and spaced from the notch of the wire accommodating arc groove.

[0021] In one possible implementation manner, a plurality of the wire blocking members are provided along the extending direction of the wire accommodating arc groove.

[0028] In one possible implementation, the fastener is a fastening screw;

[0029] A threaded hole is concavely arranged at the top end of the mounting column, and the fastening screw is fastened and mounted in the threaded hole by means of a threaded connection.

[0030] Compared with the prior art, the technical solution provided by the embodiments of the present disclosure has the following advantages:

[0031] When the cable stretching buffer device provided by the embodiment of the present disclosure is in use, the cable can be passed through the wire-containing arc groove on one side of the rotating part, so that the cable is at least partially wrapped around the rotating part, and then the rotating center hole in the rotating part is correspondingly buckled and fitted onto the mounting column of the mounting part, and the rotating arc groove in the rotating part is correspondingly buckled and fitted onto the limiting column of the mounting part, thereby realizing the installation process of the cable stretching buffer device.

The rotating part is limited to rotate at a certain angle, which is equivalent to "releasing" a certain length of the laid and fixed cable. In this way, the cable itself can be prevented from being pulled and stretched, thereby solving the problems in the prior art of the cable stretching and making abnormal noise when it is pulled and easily affecting the stability of the plug connector.

DETAILED DESCRIPTION

[0042] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0043] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0044] Combination Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present disclosure provides a cable tension buffer device, which includes a rotating member 1 and a mounting member 2; the rotating member 1 has an eccentrically arranged rotating center hole 11, and a rotating arc groove 12 arranged concentrically with the rotating center hole 11; the mounting member 2 includes a mounting column 21 inserted in the rotating center hole 11, and a limiting column 22 inserted in the rotating arc groove 12;

[0045] Among them, a wire-accommodating arc groove 13 is also opened in the outer peripheral wall of the rotating member 1 on one side close to the rotating arc groove 12; the cable can at least partially wrap the rotating member 1 through the wire-accommodating arc groove 13; when the cable is stretched, the rotating member 1 can swing back and forth around the mounting column 21, and the limiting column 22 can move relatively within the rotating arc groove 12.

[0046] When the cable stretching buffer device is installed and used, the cable can first be passed through the wire-containing arc groove 13 on one side of the rotating member 1, so that the cable is at least partially wrapped around the rotating member 1, and then the rotating center hole 11 in the rotating member 1 is correspondingly buckled and fitted onto the mounting column 21 of the mounting member 2, and the rotating arc groove 12 in the rotating member 1 is correspondingly buckled and fitted onto the limiting column 22 of the mounting member 2, so that the installation process of the cable stretching buffer device can be realized.

[0047] When one end of the cable is pulled, the cable wrapped in the rotating member 1 can drive the rotating member 1 to rotate eccentrically around the mounting post 21, and until the limiting post 22 slides relatively to one end of the rotating arc groove 12, the rotating member 1 can be limited and no longer rotate. The rotating member 1 is limited to rotate at a certain angle, which is equivalent to "releasing" a certain length of the laid and fixed cable, thereby preventing the cable itself from being pulled and stretched, thereby solving the problem of abnormal sound caused by stretching and contraction when the cable is pulled in the prior art, which easily affects the stability of the plug connector.

[0048] Moreover, the rotation angle of the rotating member 1 relative to the mounting column 21 can be not only Figure 4 The counterclockwise angle shown by the arrow in the middle can also be Figure 5 The clockwise angle indicated by the middle arrow. The two-way limited rotation of the rotating member 1 can correspond to two practical use conditions of cable stretching and resetting.

[0049] To sum up, the cable stretching buffer device of the embodiment of the present disclosure can drive the cable to swing in two directions at a limited angle through the rotating part 1 without changing the cable's own stretched and tightened state when it is pulled, thereby avoiding the problem of abnormal stretching noise when the cable is pulled and affecting the connection stability of the cable connector.

[0050] In one embodiment, the cable tension buffer device further includes an elastic reset member 3 ; the elastic reset member 3 is coaxially sleeved on the mounting column 21 , and is transmission-connected to the rotating member 1 , and can apply a unidirectional rotation elastic force to the rotating member 1 .

[0051] Specific, combined Figure 1 and Figure 3 To further explain in detail, the elastic reset member 3 is coaxially sleeved on the mounting column 21 and is transmission-connected to the rotating member 1, so that the elastic reset member 3 can apply a unidirectional rotation elastic force to the rotating member 1, so that the rotating member 1 can be kept in a fixed limited state, that is, the limit column 22 in the mounting member 2 can maintain abutment against one end of the rotating arc groove 12 in the rotating member 1. In this way, when one end of the cable is pulled, the unidirectional elastic force of the elastic reset member 3 can be temporarily overcome, so that the rotating member 1 can be temporarily limited and rotated in the opposite direction by a certain angle; when one end of the cable is no longer pulled, the unidirectional elastic force of the elastic reset member 3 can act on the rotating member 1 again, so that the rotating member 1 is reset and rotated to the initial state.

[0052] The specific arrangement of the elastic reset member 3 has the beneficial effects of simple structure, being able to apply a unidirectional rotation elastic force to the rotating member 1, and enabling the rotating member 1 to automatically reset when not subjected to other external forces.

[0053] In one embodiment, the elastic reset member 3 is a torsion spring; the mounting member 2 is further provided with a blocking platform 23 for limiting and blocking one end of the torsion spring; the rotating member 1 is further provided with a blocking edge 14 for limiting and blocking the other end of the torsion spring.

[0054] Specific, combined Figure 1 and Figure 2 To further explain in detail, the elastic return member 3 is specifically configured as a torsion spring, and one end of the torsion spring is blocked by the blocking platform 23 in the mounting member 2, and the other end is blocked by the blocking edge 14 in the rotating member 1. In this way, the torsional elastic force of the torsion spring itself can act on the rotating member 1, so that it can always have a unidirectional rotation tendency around the mounting column 21.

[0055] Of course, the elastic reset member 3 may also be specifically configured as a coil spring, a tension spring, etc., which can generate a unidirectional elastic force around the mounting column 21 circumferentially.

[0056] In one embodiment, the rotating member 1 is further provided with a wire stopper 15 corresponding to the notch of the wire arc groove 13; the wire stopper 15 and the notch of the wire arc groove 13 are arranged opposite each other, and the distance between them is smaller than the diameter of the cable.

[0057] Specific, combined Figure 1 and Figure 2 To further explain in detail, a wire stopper 15 is provided at the slot of the wire arc groove 13, and the distance between the wire stopper 15 and the slot of the wire arc groove 13 is smaller than the diameter of the cable, so that the wire stopper 15 can cover and limit the cable embedded in the wire arc groove 13 to a certain extent, thereby preventing the cable from falling off from the wire arc groove 13 during the synchronous rotation of the rotating member 1.

[0058] The specific arrangement of the wire blocking member 15 has the beneficial effects of simple structure, being able to cover and limit the cables in the wire-containing arc groove 13, and providing stability for cable installation.

[0059] In one embodiment, the wire blocking member 15 includes a connecting plate 151 and a wire blocking plate 152 which are vertically connected to each other to form an L; the connecting plate 151 is vertically connected to the side peripheral wall of the rotating member 1, and the wire blocking plate 152 is parallel and spaced from the notch of the wire arc groove 13.

[0060] Specific, combined Figure 2 To further explain in detail, the wire blocking member 15 is specifically configured as an L-shaped baffle member, and the baffle member includes a connecting plate 151 and a wire blocking plate 152 which are perpendicular to each other, and the connecting plate is vertically connected to the side outer peripheral wall of the rotating member 1, so that the connecting plate 151 can limit the distance between the wire blocking member 15 and the notch of the wire accommodating arc groove 13; the wire blocking plate 152 is spaced parallel to the notch of the wire accommodating arc groove 13, so that the wire blocking plate 152 can block the notch of the wire accommodating arc groove 13 to a certain extent.

[0061] In one embodiment, a plurality of wire blocking members 15 are provided along the extending direction of the wire accommodating arc groove 13 .

[0062] Specific, combined Figure 2 To further explain in detail, two wire stoppers 15 are arranged at intervals along the extension direction of the wire accommodating arc groove 13, so that the two wire stoppers 15 can more fully cover and limit the wire accommodating arc groove 13 on the cable, preventing the cable from falling off from the outward protrusion inside the wire accommodating arc groove 13 when the cable is pulled and rotated or reset.

[0063] Of course, the number of the wire blocking members 15 can be increased or decreased according to the actual length of the wire accommodating arc groove 13 .

[0064] In one embodiment, a notch 16 communicating with the arc accommodating groove 13 is further provided in the top side of the rotating member 1 ; the cable can be inserted into the arc accommodating groove 13 through the notch 16 .

[0065] Specific, combined Figure 2 To further explain in detail, a notch 16 communicating with the wire-accommodating arc groove 13 is also provided in the top side of the rotating member 1, so that when the cable needs to be plugged into the wire-accommodating arc groove 13, the notch 16 can be used as an initial plugging port for the cable to be plugged in, and after the cable is partially plugged into the wire-accommodating arc groove 13 through the notch 16, the cable can be squeezed along the length of the wire-accommodating arc groove 13 accordingly, so that the cable is gradually plugged into the wire-accommodating arc groove 13 along the length direction of the wire-accommodating arc groove 13.

[0066] The specific arrangement of the notch 16 has the beneficial effects of simple structure and convenient installation of the cable in the wire-containing arc groove 13 .

[0067] In one embodiment, the mounting member 2 is further provided with a supporting top edge 24 ; the supporting top edge 24 is used to abut flush with one side of the rotating member 1 along the axial direction of the mounting column 21 .

[0068] Specific, combined Figure 3 To further explain in detail, the above-mentioned support top edge 24 can be specifically connected to the peripheral wall of the limiting column 22, and a plurality of support top edges 24 can be specifically provided, for example but not limited to, a "X" cross distribution or a "M" cross distribution with respect to the limiting column 22, so that the plurality of support top edges 24 can be more evenly and flushly supported and abutted against one side of the rotating member 1, thereby further improving the installation stability of the rotating member 1 in the mounting member 2.

[0069] In one possible implementation manner, the cable tension buffer device further includes a fastener 4 ; the fastener 4 is fastened to the top end of the mounting column 21 , and blocks the rotating member 1 in a limited position along the axial direction of the mounting column 21 .

[0070] Specific, combined Figure 1 and Figure 3 To further explain in detail, a fastener 4 is provided at the top end of the mounting column 21, and the fastener 4 can limit the rotating member 1 along the axial direction of the mounting column 21, thereby preventing the rotating member 1 from falling off from the axial direction of the mounting column 21 during multiple reciprocating swings, thereby further improving the installation limiting effect of the rotating member 1 in the mounting column 21.

[0071] In one possible implementation manner, the fastener 4 is a fastening screw; a threaded hole is concavely provided at the top end of the mounting column 21, and the fastening screw is fastened and installed in the threaded hole by means of a threaded connection.

[0072] Specific, combined Figure 1 In further detail, the fastener 4 is specifically configured as a fastening screw, and a threaded hole is concavely provided at the top end of the mounting column 21, so that the fastening screw can be fastened and installed in the threaded hole by means of a threaded connection, thereby achieving clamping and limiting of the rotating member 1.

[0073] The specific method of the above-mentioned fastener 4 has the beneficial effects of simple structure, good fastening and limiting stability, and easy disassembly and assembly.

[0074] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.
