Description

Technical Field

[0001] The utility model relates to the technical field of data cables, in particular to a unidirectionally stretched silent data cable. Background Art

[0002] The retractable data cables or charging cables currently on the market all involve the structure of retracting and releasing the data cables. The technical solutions adopted all use springs to achieve the retraction and release of the data cables, and they are all bidirectionally stretched, because if only one side is pulled, there is a problem that the other end will be congested inside the casing.

[0003] The existing technical solutions all use the ball component to constrain the rotation and positioning function of the bracket in the retractable technical structure. You can refer to the existing patent technical documents CN202320228480 and CN202023046706, which are both such technical solutions. However, this technical solution has two defects: 1. Since it is a biaxially stretched data cable, it requires a variety of usage scenarios (for example: when facing an interface different from the data cable itself, you can only consider a converter or use other data interfaces.). 2. When the ball moves inside the shell, it hits the hard walls around the inside, the noise is very loud, and loose shaking will form inside the device, causing additional noise.

[0004] The purpose of this design is to solve the defects in the conventional design scheme using bidirectional stretching and balls. Utility Model Content

[0005] The purpose of the utility model is to solve the above defects and provide a unidirectionally stretched silent data cable, which can not only realize the purpose of customizing the data interface, but also achieve the silent effect of shrinking the data cable.

[0006] The purpose of the utility model is achieved by the following methods:

[0007] A unidirectionally stretched silent data cable, comprising an upper cover and a lower cover, which, when closed, form a hollow accommodating chamber, a bracket is provided inside the accommodating chamber, the bracket is used to install a spring, a data transmission line and a conductive wire board, a mounting groove is provided at the bottom of the bracket, a conductive wire board is installed between the bracket and the conductive ring rail, and elastic pins are provided below the conductive wire board to be slidably connected to the conductive ring rail. The advantage of this technical solution is that one end of the pull wire can achieve a change in length, but the other end, through the relevant technology of the conductive ring rail, allows the electrical signal to pass through, and the other output end can be in a static state, and subsequently connected to other electronic devices by welding or electrical connection, greatly expanding its scope of use. For example, it can be installed in a power bank, other electronic products that require an external power supply (mouse, keyboard, etc.) or data signals. The data cable of an electronic product can be retracted.

[0008] The above description, as a preferred solution, the conductive wire board is composed of a data board, a rotating through hole and a PCB board. The data board is fixedly mounted on the PCB board for receiving data transmitted by the data transmission line. The rotating through hole is arranged at the center of the PCB board to provide an installation channel for the upper cover and the lower cover to be covered. The PCB board provides an installation base for the data board and the rotating through hole.

[0009] As described above, as a preferred solution, an elastic pin is further provided under the data plate. The elastic pin is semicircular in shape and directly contacts the conductive ring rail to convert the original rotational motion into sliding motion.

[0010] The above description, as a preferred solution, the PCB board is also provided with a lead slot, which serves as an input port to connect the data transmission line and the data board.

[0011] The above description, as a preferred solution, a guiding device is provided between the lower cover and the bracket, and a corresponding slide groove is provided on the inner top surface of the lower cover, a guide head is provided on the guiding device, and the guiding device is embedded in the slide groove to guide the rotation of the bracket without deviating from the track.

[0013] The above description, as a preferred solution, the bottom surface of the bracket is provided with a guide track, and the guide head is embedded in the guide track to cooperate with the guiding device to prevent the bracket from rotating away from the track.

[0014] The above description, as a preferred solution, is as follows: the conductive ring track is provided with 4 ring tracks and an output end, and the data on the conductive line board is transmitted to the output end by sliding the elastic pins under the data board therein.

[0015] As described above, as a preferred solution, the inner bottom surface of the upper cover is provided with a downward fixing shaft for fixing the bracket and the mainspring.

[0016] As described above, as a preferred solution, the inner top surface of the lower cover is provided with an upward cylindrical countersunk hole for cooperating with the fixed shaft for installation and fixation.

DETAILED DESCRIPTION

[0030] The utility model designs a unidirectionally stretched silent data cable. For ease of understanding, the utility model is further described in detail in conjunction with the accompanying drawings and specific implementation cases, but is not intended to limit the utility model.

[0031] (refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Fig. 9) A unidirectionally stretched silent data cable, embodiment, the structure includes an upper cover 1, a data transmission line 4, a spring 5, a conductive wire plate 6, a bracket 3, a conductive ring track 7, a guiding device 8 and a lower cover 2. After the upper cover 1 and the lower cover 2 are covered with each other, a receiving cavity is formed. The function of the upper cover 1 and the lower cover 2 is to form a receiving cavity for accommodating other components of the product. The bracket 3 is placed in the receiving cavity to support the installation of the data transmission line 4, the spring 5 and the conductive wire plate 6. The upper inner wall of the upper cover 1 is provided with a downwardly extending fixed shaft 11, and the fixed shaft 11 passes through the through hole 31 in the middle of the bracket 3 and is inserted into the countersunk hole 21 in the middle of the lower cover 2, so that the bracket 3 can rotate around the fixed shaft 11 as the center. The data transmission line 4 is wound on the bracket 3 for transmitting data. The clockwork 5 is arranged on the bracket 3 for providing a contraction force so that the data transmission line 4 can be freely extended and retracted into the shell body so as to recover the pulled-out data transmission line 4. The conductive wire plate 6 is rotatably installed at the bottom of the bracket 3, and its function is to connect the data of the data transmission line 4 with the output terminal 72 at the bottom. The conductive ring rail 7 is fixedly installed on the lower cover 2 through the cooperation of the fixed shaft 11 and the hole. The conductive ring rail 7 is used to input the data transmitted by the conductive wire plate 6 to the output terminal 72. The guide device 8 is slidably installed on the slide groove 22 on the inner bottom surface of the lower cover 2 to reduce noise and achieve a larger stroke.

[0032] Example (reference Figure 5 , Figure 6 ), one end of the spring is arranged in the middle of the bracket 3 and passes through the open slot 111 on the fixed shaft 11 to form a fixed end, and the other end passes through the staggered slot 32 of the bracket 3 and is engaged with the bracket 3. Since the bracket 3 can rotate around the fixed shaft 11, when the data transmission line 4 is pulled out, the bracket 3 rotates, thereby tightening the spring 5, so that the spring 5 generates elastic potential energy. When the product is in the winding state, the spring 5 changes from a taut state to a relaxed state, driving the bracket 3 to rotate in the opposite direction to the pulling state, thereby achieving the purpose of winding.

[0033] Example (reference Figure 7 , Figure 8), the conductive wire board 6 is composed of a data board 61, a rotating through hole 62 and a PCB board 63. The rotating through hole 62 is arranged at the center of the PCB board 63, and its function is to provide a channel for the fixed shaft 11 to pass through. There are three data boards 61, which are arranged around the rotating through hole 62 in a triangular manner. Its function is to transmit the data transmitted by the data transmission line 4 to the output end 72 below. A semicircular elastic pin 611 is also provided below the data board 61, and each data board 61 has 4 elastic pins 611. The elastic pin 611 is used to contact the conductive ring track 7 below to convert the original rotational motion of the conductive wire board 6 into a sliding motion. The PCB board 63 is used to install the data board 61 and set the rotating through hole 62. A lead groove 631 is also provided on the PCB board 63. The lead groove 631 is used as an input port to connect the tail copper wire structure 41 of the data transmission line 4 and the data board 61. The two are connected by a lead, thereby ensuring that the user can perform a customized replacement when facing a data line interface different from the original.

[0034] Example (reference Fig. 9 ), the surface of the conductive ring track 7 is also provided with four circular tracks 71 and an output terminal 72, through which the elastic pin 611 below the data plate 61 slides, and the data on the conductive line plate 6 is transmitted to the output terminal 72.

[0035] Example (reference Figure 4 , Fig.10 ), the guide device 8 is an I-shaped structure 81, which is used to cooperate with the slide groove 22 on the lower cover 2 to form a stable and reliable sliding structure, so that the auxiliary bracket 3 will not deviate when rotating. The I-shaped structure 81 is also provided with a guide head 811, which is used to insert into the guide track 33 at the bottom of the bracket 3, and cooperate with the slide groove 22 at the bottom of the lower cover 2 to ensure that the rotation of the bracket 3 does not deviate from the track. Since there is sliding friction between the I-shaped structure 81 and the slide groove 22, the noise generated by the two is very subtle, which is greatly reduced compared with the noise generated by the collision between the ball and the surrounding hard walls and the friction between the ball and the plastic material in the prior art. At the same time, due to the characteristics of the ball, if the product is squeezed and deformed, the ball will jump out of its track or be squeezed, resulting in the loss of the telescopic function. The I-shaped structure can also greatly improve the stability of the entire product.

[0036] Example (reference Fig.11 ), the data transmission line 4 is unidirectionally stretched, one end of which is arranged at the center of the bracket 3, and the tail part is a bare copper wire structure 41, the copper wire structure is directly connected to the lead groove 631 on the conductive wire plate 6 below to form a data transmission end, and the other end is a normal USB interface data line, most of the existing technologies have been described here and will not be repeated in detail.

[0037] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as the protection scope of the present invention.
