Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The present inventors have long studied and found that, in various communication devices, a HUB (HUB) can perform regenerative shaping amplification on a received signal to expand a transmission distance of a network, and can concentrate all nodes on a node centered on itself, thereby playing an important role in network communication. Hubs often require connection to external devices through cables. At present, the cable of the concentrator in the prior art is in an exposed state, which causes that the concentrator is inconvenient to carry and store. In order to solve this technical problem, the present utility model provides the following embodiments.

As shown in fig. 1 to 5, the hub 1 described in the hub embodiment of the present utility model includes a main body 100, a cable 200, a housing 300, and a latch 400. One end of the cable 200 is connected to the main body 100. The accommodating body 300 is connected with the main body 100, the accommodating body 300 is provided with an accommodating cavity 301, a wire inlet 302 and a wire outlet 303, the wire outlet 303 is communicated with the accommodating cavity 301 and the outside, the wire inlet 302 is communicated with the accommodating cavity 301, and the cable 200 extends from the main body 100 to be accommodated in the accommodating cavity 301 through the wire inlet 302. The latch 400 is disposed in the receiving cavity 301, and the latch 400 is latched with the main body 100. The accommodating body 300 is provided with a blocking portion 310 in the accommodating cavity 301, and the latch 400 is stopped by the blocking portion 310. Wherein, the accommodating body 300 rotates around the main body 100, and the blocking part 310 pushes the latch 400 to deform to release the latch with the main body 100 along with the rotation of the accommodating body 300, and pushes the latch 400 to rotate together, and the cable 200 is extended or retracted into the accommodating cavity 301 from the outlet 303 by continuing to rotate the accommodating body 300.

The HUB 1 (HUB) belongs to a basic device in a data communication system. For example, the hub 1 may be a hardware device that requires no or little management software, and may be used as a transmission medium.

The electrical function of the hub 1 may be mainly implemented by the main body 100. The main body 100 may be connected to an external device through a cable 200 for information transmission. The cable 200 may be a cable wire or the like.

Alternatively, as shown in fig. 3 and 4, the cable 200 may have a connection end 201 and a free end 202, the connection end 201 being connected to the main body 100, the free end 202 being for connection to an external device.

When the concentrator 1 is idle, the cable 200 can be stored through the storage body 300, so that the concentrator 1 is convenient to carry and store, and the appearance of the concentrator 1 is more attractive. In some embodiments, as shown in fig. 3, the end of the cable 200 may be provided with a connection plug 203 for connection with an external device. When the hub 1 is idle, the cable 200 is accommodated in the accommodating cavity 301 to protect the connection plug 203.

In operation of the hub 1, at least a portion of the cable 200 may extend out of the receiving cavity 301 through the outlet 303 to connect to external devices. The user may drive cable 200 out of receiving cavity 301 by rotating receiving body 300 and/or body 100 such that receiving body 300 rotates in first direction a relative to body 100. The greater the angle by which the housing body 300 rotates in the first direction α with respect to the main body 100, the longer the cable 200 extends out of the housing cavity 301 until the portion of the cable 200 that can extend out of the housing cavity 301 completely extends out of the housing cavity 301. By adjusting the length of the cable 200 extending out of the accommodating cavity 301, the length of the cable 200 extending out of the accommodating cavity 301 can be adapted to the distance between the hub 1 and the external device, so that the degree of freedom of the use scene of the hub 1 is higher.

When the cable 200 extending out of the accommodating cavity 301 needs to be accommodated, the user can rotate the accommodating body 300 and/or the main body 100, so that the accommodating body 300 rotates along the second direction β opposite to the first direction α relative to the main body 100, and the cable 200 can be retracted into the accommodating cavity 301.

As shown in fig. 6 and 7, the latch 400 is latched with the main body 100 on one hand, such that the rotation of the latch 400 in the first direction α and the second direction β relative to the main body 100 is limited. The locking of the locking piece 400 with the main body 100 means that the locking piece 400 and the main body 100 can be mutually limited. For example, the latch 400 may be mutually restrained by the body 100 and the snap-forming manner. The latch 400 is stopped by the blocking portion 310, so that the latch 400 is limited to rotate in the first direction α and the second direction β relative to the housing 300. Through setting up the latch 400, can restrict the relative rotation of the receiver 300 and the main part 100, both can make cable 200 stable holding in accomodating chamber 301 at the idle in-process of concentrator 1, avoid cable 200 to stretch out accomodating chamber 301, can avoid cable 200 to take place to slide and influence the stability that concentrator 1 connects in the course of the work of concentrator 1 again.

When the user initially rotates the receiving body 300 with respect to the main body 100, the latch 400 may be elastically deformed by the initial pushing action of the blocking member to release the latch from the main body 100, thereby allowing the receiving body 300 and the main body 100 to relatively rotate. When the user further rotates the storage body 300 relative to the main body 100, the latch 400 can rotate synchronously with the storage body 300 and maintain an elastically deformed state under the further pushing action of the blocking member, and the storage body 300 and the main body 100 are continuously allowed to rotate relative to each other. When the user stops rotating the housing body 300 with respect to the main body 100, the latch 400 may be elastically deformed to return to latching with the main body 100, and the relative rotation of the housing body 300 and the main body 100 is restricted.

Alternatively, as shown in fig. 6 and 7, the portion of the cable 200 accommodated in the accommodation chamber 301 may be spirally wound. When the accommodating body 300 rotates, the outer ring of the cable 200 can slide along the circumferential direction relative to the accommodating body 300, so as to extend from the outlet 303 or retract into the accommodating cavity 301.

Optionally, the latch 400 is made of engineering plastic, such as PC/POM, so that the latch 400 has a certain mechanical strength and is elastically deformable.

Optionally, as shown in fig. 3, a non-slip pad 370 is disposed on a side of the accommodating body 300 facing away from the main body 100, so that friction between the side of the accommodating body 300 facing away from the main body 100 and the table top can be increased when the hub 1 is placed on the table top, and the hub 1 is prevented from sliding.

Through main part 100, the one end of cable 200 is connected with main part 100, accomodate body 300 and main part 100 are connected, accomodate body 300 has been seted up and has been accomodate the chamber 301, inlet 302 and outlet 303, outlet 303 intercommunication accomodate chamber 301 with the external world, the cable 200 extends to the holding in accomodate chamber 301 through inlet 302 from main part 100, the latch 400 sets up in accomodate chamber 301, latch 400 and main part 100 kayser, accomodate body 300 is equipped with blocking portion 310 in accomodate chamber 301, latch 400 backstop is in blocking portion 310, wherein accomodate body 300 rotates around main part 100, blocking portion 310 pushes away latch 400 deformation to remove the kayser with main part 100 along with accomodating body 300 rotation, and promote latch 400 rotation altogether, continue to rotate accomodate body 300 and stretch out or retract to accomodate chamber 301 by outlet 303 to with cable 200, when concentrator 1 is idle, can accomodate cable 200 through accomodate body 300, make the outward appearance of cable 1 more pleasing to the eye, still can play the guard action to cable 200's connection plug, when accomodate 1, the length of cable 200 is adjusted to have a distance between the outside through accomodating chamber 301 and the cable 200, thereby can be adjusted to the distance is higher than the external world by the device is used to the cable 1.

Alternatively, as shown in fig. 6 and 8, the main body 100 is provided with the tooth groove 101, and the latch 400 includes a resilient arm 410 and a latch 411 provided on the resilient arm 410, the latch 411 being engaged with the tooth groove 101.

The blocking portion 310 includes a first limiting portion 311 and a second limiting portion 312 that are disposed at intervals, wherein one end of the elastic arm 410, where the latch 411 is disposed, is disposed between the first limiting portion 311 and the second limiting portion 312.

The elastic arm 410 can elastically deform and drive the latch 411 to disengage from the tooth slot 101 when elastically deformed, so that the latch 400 is released from the main body 100.

The first limiting portion 311 may abut against the elastic arm 410 from one side of the elastic arm 410 to stop the latch 400, thereby limiting the latch 400 from rotating in the first direction α relative to the housing 300. The second limiting portion 312 may abut against the elastic arm 410 from the other side of the elastic arm 410 to stop the latch 400, thereby limiting the latch 400 from rotating in the second direction β relative to the housing 300.

When the user initially rotates the storage body 300 along the first direction α relative to the main body 100, the elastic arm 410 can be elastically deformed under the pushing action of the second limiting portion 312, so that the latch 400 is released from the main body 100, and the storage body 300 and the main body 100 are allowed to rotate relative to each other. Optionally, the housing 300 also rotates along the first direction α relative to the latch 400 in this process, so that the first limiting portion 311 is away from the elastic arm 410 and abuts against other portions (e.g. the stopping portion 412) of the latch 400.

When the user further rotates the storage body 300 along the first direction α relative to the main body 100, the latch 400 can rotate synchronously with the storage body 300 and maintain an elastically deformed state under the pushing action of the first limiting portion 311 and/or the second limiting portion 312, so as to continuously allow the storage body 300 and the main body 100 to rotate relative to each other.

Similarly, when the user initially rotates the storage body 300 along the second direction β relative to the main body 100, the elastic arm 410 can be elastically deformed under the pushing action of the first limiting portion 311, so that the latch 400 is released from the main body 100, and the storage body 300 and the main body 100 are allowed to rotate relatively. Optionally, the housing 300 also rotates in the second direction β relative to the latch 400 in this process, so that the second limiting portion 312 is away from the elastic arm 410 and abuts against other portions (e.g. the stopping portion 412) of the latch 400.

When the user further rotates the storage body 300 along the second direction β relative to the main body 100, the latch 400 can rotate synchronously with the storage body 300 and maintain the elastically deformed state under the pushing action of the first limiting portion 311 and/or the second limiting portion 312, so as to continuously allow the storage body 300 and the main body 100 to rotate relative to each other.

When the user stops rotating the receiving body 300 with respect to the main body 100, the elastic arm 410 may be elastically deformed to return so that the latch 411 is engaged with the slot 101.

The number of the tooth grooves 101 is plural, and the plurality of tooth grooves 101 may be uniformly distributed in the circumferential direction. With each angular rotation of the latch 400 relative to the body 100, the teeth 411 may engage different tooth slots 101. For example, the number of the tooth grooves 101 is 60, and the latch 411 may be engaged with one tooth groove 101 every 6 ° of rotation of the latch 400 with respect to the main body 100.

Alternatively, as shown in fig. 9, the number of latches 411 on the resilient arm 410 may be one, two or more.

Alternatively, as shown in fig. 6 and 10, the body 100 is provided with a receiving groove 102 facing the receiving body 300, and the tooth grooves 101 are provided on an annular inner wall of the receiving groove 102. The plurality of tooth grooves 101 may be uniformly distributed in the circumferential direction on the annular inner wall of the receiving groove 102.

The elastic arms 410 include a plurality of evenly distributed blocking portions 310, the blocking portions 310 and the elastic arms 410 are the same in number, and one end of each elastic arm 410 provided with a latch 411 is disposed between the first limiting portion 311 and the second limiting portion 312 of the corresponding blocking portion 310.

By providing a plurality of elastic arms 410, the stability of the latch 400 to the main body 100 can be improved. The plurality of elastic arms 410 can be uniformly distributed along the circumferential direction, so that the stress between the locking member 400 and the main body 100 is uniformly distributed, and the stability of locking the locking member 400 and the main body 100 is further improved. The blocking parts 310 and the elastic arms 410 are arranged in a one-to-one correspondence, so that the stress between the locking piece 400 and the containing body 300 is evenly distributed, and the stability of the containing body 300 for stopping the locking piece 400 is improved.

Optionally, as shown in fig. 6 and 8, the elastic arm 410 further extends with a stop portion 412, and the stop portion 412 extends to the outer sides of the first limiting portion 311 and the second limiting portion 312. The first limiting portion 311 or the second limiting portion 312 rotates with the accommodating body 300 to stop at the stop portion 412, so as to push the latch 400 to rotate.

The outer sides of the first limiting portion 311 and the second limiting portion 312, that is, the side of the first limiting portion 311 and the second limiting portion 312 away from the rotation axis. The stopper portion 412 extends to the outside of the first and second stopper portions 311 and 312 to facilitate stopping the first and second stopper portions 311 and 312.

The first limiting portion 311 and the second limiting portion 312 may be disposed between the two stopping portions 412 along the circumferential direction, so that when the accommodating body 300 rotates along the first direction α or the second direction β relative to the latch 400, the stopping portions 412 can abut against the first limiting portion 311 or the second limiting portion 312.

Specifically, during the process that the user rotates the storage body 300 in the first direction α with respect to the main body 100, the storage body 300 also rotates in the first direction α with respect to the latch 400, and drives the first limiting portion 311 to rotate in the first direction α with respect to the latch 400 until the first limiting portion 311 rotates by γ degrees and then abuts against the corresponding stopping portion 412, so that the corresponding stopping portion 412 forms a stop for the first limiting portion 311. When the user further rotates the storage body 300 along the first direction α relative to the main body 100, under the pushing action of the first limiting portion 311 on the corresponding stopping portion 412, the latch 400 can rotate synchronously with the storage body 300 and maintain the elastically deformed state, so as to continuously allow the storage body 300 and the main body 100 to rotate relatively.

Similarly, in the process of primarily rotating the storage body 300 in the second direction β relative to the main body 100 by the user, the storage body 300 also rotates in the second direction β relative to the latch 400, and drives the second limiting portion 312 to rotate in the second direction β relative to the latch 400 until the second limiting portion 312 abuts against the corresponding stopping portion 412, so that the corresponding stopping portion 412 forms a stop against the second limiting portion 312. When the user further rotates the storage body 300 along the second direction β relative to the main body 100, the latch 400 can rotate synchronously with the storage body 300 and maintain the elastically deformed state under the pushing action of the second limiting portion 312 on the corresponding stop portion 412, so as to continuously allow the storage body 300 and the main body 100 to rotate relatively.

Alternatively, as shown in fig. 6 and 8, the plurality of elastic arms 410 are uniformly distributed along the circumferential direction, the plurality of stopper portions 412 are also uniformly distributed along the circumferential direction, and the first stopper portions 311 and the second stopper portions 312 which are the same as the stopper portions 412 are also uniformly distributed along the circumferential direction, so that one first stopper portion 311 and one second stopper portion 312 are respectively provided between every two adjacent stopper portions 412 along the circumferential direction, and one stopper portion 412 is respectively provided between every two adjacent stopper portions 310 along the circumferential direction. One side surface of the stop portion 412 may be abutted by the first limiting portion 311 of one blocking portion 310, and the other side surface of the stop portion 412 may be abutted by the second limiting portion 312 of the other blocking portion 310. For example, the number of the elastic arms 410, the stopper portions 412, the first stopper portions 311, and the second stopper portions 312 is 3.

Alternatively, as shown in fig. 9, the plurality of resilient arms 410 extend helically about the axis of rotation.

Alternatively, as shown in fig. 6, 8 and 9, one end of the first limiting portion 311 and one end of the second limiting portion 312 have a first inclined surface 313, respectively, and the elastic arm 410 has two second inclined surfaces 413 disposed opposite to each other, and the first limiting portion 311 and the second limiting portion 312 abut against the second inclined surfaces 413 through the first inclined surfaces 313 to compress the elastic arm 410.

The first inclined surface 313 of the first limiting portion 311 abuts against the second inclined surface 413, so that the first limiting portion 311 can stop the latch 400, and the latch 400 is limited to rotate along the first direction α relative to the housing 300. The second limiting portion 312 can stop the latch 400 by the first inclined surface 313 of the second limiting portion 312 abutting against the other second inclined surface 413, so as to limit the latch 400 to rotate along the second direction β relative to the housing 300.

When the user rotates the storage body 300 in the first direction α with respect to the main body 100, the elastic arm 410 can elastically deform under the pushing action of the first inclined surface 313 of the second limiting portion 312 on the other second inclined surface 413, so that the latch 400 is released from the main body 100. When the user rotates the housing 300 in the second direction β with respect to the main body 100, the elastic arm 410 can also elastically deform under the pushing action of the first inclined surface 313 of the first limiting portion 311 on the second inclined surface 413, so that the latch 400 and the main body 100 are released from the latch.

Alternatively, as shown in fig. 6 and 8, the other ends of the first and second limiting portions 311 and 312 rotate with the housing 300 to stop against the stop portion 412.

When the user rotates the storage body 300 further in the first direction α with respect to the main body 100, the first inclined surface 313 of the second limiting portion 312 abuts against the other second inclined surface 413, and at the same time, one end of the first limiting portion 311 away from the first inclined surface 313 abuts against the corresponding stop portion 412. When the user further rotates the storage body 300 along the second direction β relative to the main body 100, the first inclined surface 313 of the first limiting portion 311 abuts against the second inclined surface 413, and at the same time, one end of the second limiting portion 312 away from the first inclined surface 313 abuts against the corresponding stop portion 412.

Optionally, as shown in fig. 6 and 11, the hub 1 further includes an elastic member 500 disposed in the accommodating cavity 301, where the elastic member 500 is fixed on an inner sidewall of the accommodating cavity 301, and the elastic member 500 elastically abuts against the cable 200.

The portion of the cable 200 accommodated in the accommodating cavity 301 may be spirally wound, and the elastic member 500 may elastically abut against an outer ring of the portion of the cable 200 accommodated in the accommodating cavity 301. When the accommodating body 300 rotates such that the outer ring of the cable 200 is extended from the outlet 303, the elastic member 500 may restrict the outer ring of the cable 200 from sliding in the radial direction in the accommodating cavity 301, so that the outer ring of the cable 200 can slide in the circumferential direction, thereby enabling the cable 200 to be extended from the outlet 303 quickly and smoothly. Meanwhile, the elastic member 500 has elasticity, and can shrink in a direction away from the cable 200 when the cable 200 in the accommodating cavity 301 is compactly arranged, so that the situation that the cable 200 is blocked in the accommodating cavity 301 and cannot slide due to overlarge friction between the outer ring and the inner ring of the cable 200 can be avoided.

Alternatively, as shown in fig. 4 and 6, the elastic member 500 has an open ring shape, the opening 501 of the elastic member 500 is aligned with the outlet 303, and the elastic member 500 includes a plurality of propping portions 502 protruding into the accommodating cavity 301, where the propping portions 502 butt against the cable 200.

The provision of the resilient member 500 with the opening 501 aligned with the outlet 303 may give way for the cable 200 to extend or retract from the receiving cavity 301. The abutment 502 can be elastically configured by adjusting the degree of protrusion into the receiving cavity 301. When the elastic member 500 is compressed, the degree of protrusion of the abutting portion 502 into the accommodating chamber 301 becomes smaller, and the shape of the elastic member 500 approaches a ring shape.

Alternatively, the elastic member 500 has a wave shape, and the amplitude of the wave shape varies with the deformation of the elastic member 500.

Alternatively, the elastic member 500 is a unitary structure, facilitating the installation of the elastic member 500.

Alternatively, the inner wall of the elastic member 500 is smooth, so that friction with the outer circumference of the cable 200 can be reduced. For example, the elastic member 500 is a metal sheet with a smooth surface.

Alternatively, as shown in fig. 6 and 11, the accommodating body 300 includes a first flange 320 and a second flange 330 that are disposed at intervals, the first flange 320 is located in the second flange 330, the first flange 320 encloses the accommodating cavity 301, the first flange 320 is provided with through holes 321 at intervals, the elastic member 500 is buckled between the first flange 320 and the second flange 330, and the propping portion 502 extends into the accommodating cavity 301 through the through holes 321.

In the mounting of the elastic member 500, the elastic member 500 may be inserted between the first and second flanges 320 and 330 in the rotation axis direction, and the abutting portion 502 may be inserted into the receiving chamber 301 through the through hole 321, and then the receiving body 300 and the main body 100 may be connected to restrain the elastic member 500 between the receiving body 300 and the main body 100 in the rotation axis direction.
