Description

Technical Field

[0001] This application relates to the technical field of mechanical equipment, and particularly to a twisted pair preparation device and a twisted pair preparation system. Background Art

[0002] Currently, in in-vehicle controllers, the vast majority of controllers use CAN bus or in-vehicle Ethernet for communication, and the physical transmission media used in both communication methods are twisted pairs. The existing small twisted pairs are prepared in the following two ways:

[0003] Solution 1: Use a finished twisted pair wire harness made by a wire harness factory. The development and test personnel intercept the corresponding length of the twisted pair according to the requirements for use. However, this method has the following disadvantages: Since the twisted pairs prepared by the wire harness factory are generally relatively long, the development and test personnel cannot carry them all and can only intercept a part. Generally, for safety reasons, an extra section of the wire harness will be intercepted. This results in wire harness redundancy. If the wire harness of the appropriate length is intercepted again, the remaining wire ends cannot be reused, causing waste.

[0004] Solution 2: The development and test personnel carry ordinary wires. During testing or development, the wires are intercepted according to the required length, and then the two wires are manually twisted to manually produce a twisted pair. However, this method has the following disadvantages: When manually producing a twisted pair, it is more troublesome if the required wire harness length is long. At the same time, manually rotating the wire harness cannot accurately control the pitch, resulting in the inability to effectively utilize the anti-interference ability of the twisted pair, and the production process is time-consuming and laborious. At the same time, because the length of the single-strand wire will be shortened after being made into a twisted pair, it is difficult to measure the length when intercepting the wire harness.

[0005] Therefore, there is an urgent need for a twisted pair preparation device and a twisted pair preparation system to solve the technical problems existing in the prior art to a certain extent. Summary of the Invention

[0074] Example 1

[0075] Currently, there are two conventional preparation methods for twisted pairs applied in vehicle-mounted controllers. As described in the background art, no matter which conventional preparation method is used, there are technical problems of troublesome production and waste. To overcome the disadvantages existing in the prior art, the present application provides a twisted pair preparation device. The following combines Figures 1 - 14 As shown, a twisted pair preparation device provided by the present application is described in detail.

[0076] The twisted pair preparation device includes a power mechanism 1, and the power mechanism 1 has a driving part 101 and a driven part 102; the driving part 101 can drive the driven part 102 to rotate along a first direction 103 or a second direction 104. Specifically, in combination with Figure 1As shown, the driving part 101 includes a driving handle 105 and a fixed handle 106; one end of the driving handle 105 is connected to one end of the fixed handle 106 at a first preset angle through a spring hinge; that is, one end of the driving handle 105 and the fixed handle 106 are fixedly connected, and the other end is open. Optionally, during actual use, the fixed handle 106 is fixed, the driving handle 105 is located above the fixed handle 106, and the driving handle 105 can move towards or away from the fixed handle 106; thus realizing the movement of semi-closure or opening. Further specifically, applying a force can cause the driving handle 105 to move towards the fixed handle 106, making the driving handle 105 semi-closed to the fixed handle 106. When the applied force is withdrawn, since one end of the driving handle 105 and one end of the fixed handle 106 are connected by a spring hinge, then under the reset action of the spring hinge, the driving handle 105 will move away from the fixed handle 106, thereby realizing the driving handle 105 to open the fixed handle 106.

[0077] The above-mentioned first preset angle is optionally between 60° - 90°; since the driving handle 105 moves towards the fixed handle 106, the first preset angle is not fixed during actual application. In the initial state, the first preset angle is preferably 90°, that is to say, the driving handle 105 and the fixed handle 106 are perpendicular. As the driving handle 105 gradually approaches the fixed handle 106, this first preset angle gradually decreases and finally decreases to 60°.

[0078] Specifically, in combination with Figure 1 As shown, the driven part 102 includes a rack 107 and a main gear 108; the main gear 108 is optionally arranged on the fixed handle 106, and of course, it can also be arranged on the driving handle 105 if the structural conditions permit. In combination with Figure 1 As shown, the rack 107 has a certain arc, one end of which is fixed to the driving handle 105, the other end extends towards the fixed handle 106, and is meshed with the main gear 108.

[0079] In combination with Figure 1 As shown, when applying a force to drive the driving handle 105 to move towards the fixed handle 106, the rack 107 will also move together with the driving handle 105 and can press down towards the fixed handle 106. Since the rack 107 is meshed with the gear, the main gear 108 will be driven to rotate in the first direction 103. When the applied force is withdrawn, the reset of the spring hinge will cause the driving handle 105 to move away from the fixed handle 106, that is, the driving handle 105 will rebound; at this time, the rack 107 will also move together with the driving handle 105, and at this time, the main gear 108 will be driven to move in the second direction 104.

[0080] According to Figure 1 the placement perspective as an example, the above-mentioned first direction 103 refers to the clockwise direction, and the above-mentioned second direction 104 refers to the counterclockwise direction. That is, when the driving handle 105 moves towards the direction close to the fixed handle 106, the main gear 108 can be driven to rotate in the clockwise direction, and when the driving handle 105 moves towards the direction away from the fixed handle 106, the main gear 108 can be driven to rotate in the counterclockwise direction.

[0081] The twisted pair preparation device includes a winding mechanism 2; the winding mechanism 2 has a wire threading part 201, a winding part 202, and a transmission part 203. Specifically, the transmission part 203 is arranged on the driven part 102, and when the driven part 102 rotates in the first direction 103, the transmission part 203 rotates along with the driven part 102 in the first direction 103. When the driven part 102 rotates in the second direction 104, the transmission part 203 does not rotate along with the driven part 102. In this way, when the user repeatedly drives the driving handle 105 towards the fixed handle 106, the transmission part 203 can be continuously moved in the clockwise direction. Specifically, one end of the winding part 202 is arranged on the transmission part 203, and the other end is provided with a wire threading part 201 for conducting the wire harness at intervals; then when the transmission part 203 rotates continuously in the clockwise direction, the winding part 202 rotates along with the transmission part 203 in the clockwise direction, and when the winding part 202 rotates in the clockwise direction, the winding part 202 can wind the wire harness conducted through the wire threading part 201 into one body.

[0082] In summary, the present application uses the power mechanism 1 to provide rotational power to the winding mechanism 2, so that the winding mechanism 2 can wind at least two wire harnesses into one body, thereby realizing the production of twisted pairs. In this process, there is no need for manual winding, which overcomes the technical problems of time-consuming and laborious in the prior art of manual winding on site; in addition, twisted pairs can be made at the construction site, and there is no waste caused by excessive interception of twisted pairs.

[0083] In this embodiment, in combination with Figure 5 and Figure 6 as shown, the transmission part 203 is a ratchet 204 and a rotating shaft 205; the ratchet 204 is arranged in the main gear 108 and is arranged on the fixed handle 106 through the rotating shaft 205. Since the transmission part 203 is a structure of a ratchet 204, when the main gear 108 rotates in the clockwise direction, the ratchet 204 can also rotate in the clockwise direction. When the main gear 108 rotates counterclockwise, the ratchet 204 does not rotate. Then when the user repeatedly drives the driving handle 105 towards the fixed handle 106, the continuous clockwise movement of the ratchet 204 can be realized. In addition, since the ratchet 204 and the rotating shaft 205 are fixed together, when the ratchet 204 moves in the clockwise direction, the rotating shaft 205 will also move in the clockwise direction.

[0084] The above-described ratchet wheel 204 is disposed within the main gear 108 and is disposed on the fixed handle 106 through the rotating shaft 205, which can be understood as: the rotating shaft 205 is rotatably disposed on the fixed handle 106, the ratchet wheel 204 is fixedly sleeved on the rotating shaft 205, and the main gear 108 is sleeved outside the ratchet wheel 204.

[0085] Combined with Figures 2 - 4 As shown, the winding part 202 includes a winding arm and a connecting rod 207; wherein, there are at least two winding arms. Here, taking two winding arms as an example, the two winding arms are respectively the first winding arm 206 and the second winding arm 208 for detailed description. Combined with Figure 5 and Figure 6 As shown, the ratchet wheel 204 is provided with two slots 218 facing the rotating shaft 205. One ends of the first winding arm 206 and the second winding arm 208 are respectively inserted into the slots 218 at a second preset angle, so that one ends of the first winding arm 206 and the second winding arm 208 are connected to the rotating shaft 205 at a second preset angle. Additionally, preferably, the first winding arm 206 and the second winding arm 208 are symmetrically arranged about the axis of the rotating shaft 205. The above-mentioned second preset angle can be selected as 60°, and the angle between the first winding arm 206 and the second winding arm 208 is 120°.

[0086] Combined with Figures 2 - 4 As shown, the winding part 202 further includes a connecting rod 207. Both ends of the connecting rod 207 are connected between the first winding arm 206 and the second winding arm 208, that is, the first winding arm 206, the second winding arm 208, and the connecting rod 207 form an isosceles triangle structure with a vertex angle of 120°.

[0087] During the actual use process, when the transmission shaft rotates in the clockwise direction, the isosceles triangle structure formed by the winding arm and the connecting rod 207 rotates in the clockwise direction along with the transmission shaft.

[0088] There are the following two structures for the threading part 201, which will be elaborated in detail below with reference to the accompanying drawings.

[0089] The first structure of the threading part 201, combined with Figure 2 As shown, the threading part 201 includes a slider, an adjusting long crank 210, an adjusting short crank 211, and a locking member 212. Specifically, both the upper and lower sides of the connecting rod 207 are provided with vertically extending sliding grooves 215. The upper sliding groove 215 is the first sliding groove 215, and the lower sliding groove 215 is the second sliding groove 215. There are two sliders, namely the first slider 209 and the second slider 213 respectively. The first slider 209 is located within the first sliding groove 215 and can slide within the first sliding groove 215; the second slider 213 is located within the second sliding groove 215 and can slide within the second sliding groove 215.

[0090] Furthermore, through holes 214 for conducting wire harnesses are formed in both the first slider 209 and the second slider 213; the axis of the through hole 214 is parallel to the axis of the rotating shaft 205.

[0091] Specifically, the adjusting long crank 210 is arranged on the connecting rod 207 at a third preset angle through the locking member 212, and its two ends are respectively hinged to the adjusting short crank 211. The ends of the adjusting short crank 211 away from the adjusting long crank 210 are respectively hinged to the first slider 209 and the second slider 213; the size of the third preset angle can be adjusted through the locking member 212, and the distance between the two sliders can be adjusted through the adjusting short crank 211 to adjust the pitch of the wire harness.

[0092] Furthermore, fixed shafts 216 protrude from the first slider 209 and the second slider 213, and the two adjusting short cranks 211 are respectively connected to the fixed shafts 216 on the first slider 209 and the second slider 213.

[0093] Furthermore, the locking member 212 is a locking nut 217, and the center of the adjusting long crank 210 is on the axis of the rotating shaft 205. That is, when installing the adjusting long crank 210 on the connecting rod 207 using the locking nut 217, it is necessary to ensure that the center of the adjusting long crank 210 is on the axis of the rotating shaft 205.

[0094] Furthermore, since the center of the adjusting long crank 210 is fixed on the connecting rod 207, and since the two ends of the adjusting long crank 210 are respectively connected to the two sliders through the adjusting short cranks 211, the distance from the first slider 209 to the center of the adjusting long crank 210 is equal to the distance from the second slider 213 to the center of the adjusting long crank 210. Also, since the center of the adjusting long crank 210 is on the axis of the rotating shaft 205, when the winding part 202 rotates clockwise, the two wire harnesses passing through the two sliders can be stably wound together with an equal pitch.

[0095] Furthermore, by adjusting the locking member 212, the size of the third preset angle between the adjusting long crank 210 and the connecting rod 207 can be changed, and by changing the size of the third preset angle, the distances from the first slider 209 and the second slider 213 to the axis of the rotating shaft 205 can be adjusted.

[0096] When making twisted pair wires, first, the user needs to determine the pitch of the required twisted pair wires. Then, unscrew the locking member 212, adjust the position of one of the sliders according to the pitch of the required twisted pair wires. After adjusting the position of one slider, the position of the other slider will be adjusted naturally. Finally, after adjustment, tighten the locking member 212 to fix the adjusting long crank 210 on the connecting rod 207. When the adjusting long crank 210 is fixed on the connecting rod 207, the two sliders are fixed, and thus the pitch is fixed.

[0097] The second structure of the wire threading part 201. The wire threading part 201 includes sliders and a locking member 212. Through holes 214 for conducting the wire harness are formed on the sliders. There are two sliders, and a sliding groove 215 is formed on the connecting rod 207, and the two sliders are respectively located in the sliding groove 215. The locking member 212 can adjust the position where the slider is locked and positioned on the connecting rod 207 to adjust the pitch of the wire harness.

[0098] Furthermore, the two sliders are symmetric about the axis of the rotating shaft 205 and are arranged on the connecting rod 207 through the locking member 212. The locking member 212 can adjust the distance between the slider and the axis of the rotating shaft 205 to adjust the pitch of the wire harness.

[0099] Even further, the locking member 212 is a locking nut 217, which can abut the slider against the side wall of the sliding groove 215, thereby realizing the fixation of the position of the slider. Using the locking member 212 to adjust the distances between the two sliders and the axis of the rotating shaft 205 to be the same ensures the stability of the winding.

[0100] In this embodiment, after the above-mentioned wire winding mechanism 2 completes the winding work of two wire harnesses, the wire outlet mechanism 3 is responsible for pulling out the wound wire harness from the other end to ensure the continuous production of the wire harness. Combining Figures 7 - 14 The structure of the wire outlet mechanism 3 is elaborated in detail. The wire outlet mechanism 3 includes an active friction part 301, a driven friction part 302, and a wire outlet part 303.

[0101] Specifically, a wire outlet hole 304 penetrating the fixed handle 106 is formed on the rotating shaft 205 along its axis direction. The wire harness introduced through the two through holes 214 can finally be led out through the through hole 305 of the rotating shaft 205.

[0102] Specifically, the active friction part 301 is an active friction wheel 307. The active friction wheel 307 is sleeved on the rotating shaft 205 and is located between the ratchet wheel 204 and the fixed handle 106. Since the active friction wheel 307 is sleeved on the rotating shaft 205, when the rotating shaft 205 rotates along the first direction 103, the active friction wheel 307 will be driven to rotate along the first direction 103 at the same time. Optionally, the active friction wheel 307 is of a disc structure.

[0103] Further, two through holes 305 are formed in the fixed handle 106 corresponding to the positions of the active friction portions 301. The connection line between the two through holes 305 is parallel to the diameter of the active friction portion 301, that is, the two through holes are located on the diameter of the active friction portion 301.

[0104] Specifically, the driven friction portion 302 is a driven friction wheel 308; two driven friction wheels 308 are provided and respectively correspond to the two through holes 305. The other two driven friction wheels 308 are frictionally and perpendicularly connected to the active friction portion 301 through the through holes 214, and one ends of the two driven friction wheels 308 facing away from the active friction wheel 307 are respectively connected to the two wire outlet portions 303.

[0105] Specifically, a conduction gap 306 corresponding to the wire outlet hole 304 is formed between the two wire outlet portions 303; the wire harness wound integrally by the winding mechanism 2 sequentially passes through the wire outlet hole 304 and the conduction gap 306 and is led out.

[0106] Further, as shown in Figures 7 - 14 The wire outlet portion 303 includes a support base 309, a first gear 310, a second gear 311, a first rotating shaft 312, a second rotating shaft 313, a connecting shaft 314, and a wire outlet friction wheel 315; wherein, the support base 309 is located beside the through hole 305 and fixedly arranged on the fixed handle 106, and the first rotating shaft 312 sequentially passes through the support base 309, the driven friction wheel 308, and the first gear 310; the wire outlet friction wheel 315 at least covers a part of the wire outlet hole 304; the second rotating shaft 313 is connected to the first rotating shaft 312 through the connecting shaft 314, the second rotating shaft 313 sequentially passes through the second gear 311 and the wire outlet friction wheel 315, and the first gear 310 is meshed and connected with the second gear 311.

[0107] The principle of the above wire outlet mechanism 3 is as follows: The ratchet wheel 204 and the active friction wheel 307 are fixed together through the rotating shaft 205. The passive friction wheel is fixed on the side of the fixed handle 106 away from the friction wheel and perpendicular to the active friction wheel 307, and the active friction wheel 307 and the active friction wheel 307 are driven by friction force. When the ratchet wheel 204 rotates in the clockwise direction, the active friction wheel 307 also rotates in the clockwise direction; when the active friction wheel 307 rotates in the clockwise direction, it drives the driven friction wheel 308 to rotate; when the driven friction wheel 308 rotates in the clockwise direction, the wire outlet friction wheel 315 can be driven to rotate through the first rotating shaft 312, the first gear 310, the second gear 311, and the second rotating shaft 313. Since the two driven friction wheels 308 are located in the diameter direction of the active friction wheel 307, the two driven friction wheels 308 will rotate in opposite directions, and further the two wire outlet friction wheels 315 will also rotate in opposite directions. Then when the wound wire harness is led out through the wire outlet hole 304, it is transmitted by the two wire outlet friction wheels 315 through the conduction gap 306.

[0108] In summary, the two wire harnesses are introduced through the through holes 214 in the middle of the two sliders respectively. When the user presses the driving handle 105, the driving ratchet 204 starts to rotate, and the winding arm will continuously provide winding power for the two wire harnesses according to the selected rotation pitch. At the same time, the power chain of the active friction wheel 307-passive friction wheel-first gear 310-second gear 311 is finally converted into the rotation of the outlet friction wheel 315. Through the coordinated rotation of the two symmetrical outlet friction wheels 315, the wound wire harness will be clamped through the outlet hole 304 and the conductive gap 306 and discharged from the entire device, completing the production process of the twisted pair cable.
