Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The inventors of the present application have studied for a long time and found that terminals are widely used as contact electrodes in electronic devices such as mobile phones, tablet computers, headphones, computers, etc., and other electrical devices such as sockets, switches, etc., which have very wide application fields. The other electrode can be effectively contacted by the contact terminal. In the related art, a spring piece is generally used as a contact terminal. The spring plates are roughly classified into two types. One is a relatively flat spring sheet with no arch, the other is a sharp-angle arch, the arch part is constructed into a triangle shape, and the sharp-angle part is used for abutting against the other electrode. As such, it is common in the industry to consider that the spring is often suitable for use in static electrical connection scenarios (i.e., there is relative motion between the electrodes) and unsuitable for use in dynamic electrical connection scenarios. In order to solve or improve the above technical problems, the present application proposes the following embodiments.

The following present wire containment device embodiments exemplarily describe an exemplary structure of the wire containment device 10.

As shown in fig. 1 and 2, the wire containment apparatus 10 may include a bracket assembly 100 and an electrical connection assembly 200.

The bracket assembly 100 is used to wrap the wire 20. The electrical connection assembly 200 is used for electrically conducting the wires 20. The electrical connection assembly 200 is connected to the bracket assembly 100 and electrically connected to the conductive wire 20. There may be relative movement within the electrical connection assembly 200 and electrical connection to the wires 20 may be maintained during the relative movement.

The bracket assembly 100 may include a fixed seat 110, a mount 120, and a movable seat 130 connected to each other. In which fig. 1 shows a schematic perspective view of the wire housing apparatus 10, and in particular, an assembly relationship of the fixing base 110 and the mounting base 120 may be shown from an external perspective structure.

Fig. 2 shows a schematic exploded structure of the wire housing device 10. As shown in fig. 2 and 3, the mounting base 120 and the fixing base 110 may be disposed on two sides of the movable base 130, respectively, and the mounting base 120 and the fixing base 110 are relatively fixed. The mounting base 120 and the fixing base 110 may be connected to each other to form the receiving space 101. Although the accommodation space 101 is shown in fig. 2 as being marked at the mounting base 120, it is shown as a space enclosed after the connection between the mounting base 120 and the fixing base 110, and may be shown in fig. 3. The movable seat 130 and the electrical connection assembly 200 are both disposed in the accommodating space 101. Optionally, the fixed seat 110 and the movable seat 130 may be movably connected, and the two may perform a relative motion therebetween. The lead 20 may be received in the movable seat 130. The movable base 130 moves relative to the fixed base 110, so that the wire 20 is received in the movable base 130 or pulled out of the movable base 130. Optionally, the fixed base 110 and the movable base 130 are rotatably connected. In addition to the rotatable connection, the fixed base 110 and the movable base 130 may also be slidably connected. Of course, the movable connection between the fixed base 110 and the movable element may be other connection manners, such as swinging, etc., which are not described herein.

As shown in fig. 2, for example, the fixed seat 110 and the movable seat 130 can rotate relatively about a predetermined axis. The periphery of the movable seat 130 is provided with a wire containing groove 131 along the circumferential direction, the wire 20 is wound in the Rong Xiancao, one end of the wire 20 is fixed on the movable seat 130, and the other end of the wire 20 extends out of the movable seat 130. The other end of the wire 20 can be pulled by a user to drive the movable base 130 to rotate relative to the fixed base 110.

As shown in fig. 2, the movable seat 130 may have a rotation shaft 132 with a preset axis as an axis. Of course, the rotating shaft 132 may extend out of two opposite sides of the movable base 130. The fixed seat 110 is disposed on one side of the movable seat 130 in the direction of the preset axis, and the rotating shaft 132 penetrates the fixed seat 110. The mounting base 120 may be disposed on the other side of the movable base 130 in the direction of the preset axis, and the rotating shaft 132 may be rotatably supported on the mounting base 120. In other words, the rotating shaft 132 extends out of two opposite sides of the movable base 130, and is rotatably supported by the mounting base 120 and the fixed base 110.

As shown in fig. 2 and 3, a coil spring receiving groove 112 may be further provided at a side of the fixing base 110 facing away from the receiving space 101, the rotation shaft 132 may be penetrated into the coil spring receiving groove 112, and a coil spring 113 may be provided in the coil spring receiving groove 112. The coil spring 113 may be sleeved on the rotating shaft 132, and is elastically connected between the rotating shaft 132 and the fixed seat 110, for resetting the movable seat 130. Optionally, the fixing base 110 is further provided with a protective cover 114 for covering the coil spring accommodating groove 112, and the protective cover 114 is covered on the coil spring accommodating groove 112 for protecting the coil spring 113.

As shown in fig. 2 and 3, a sliding groove 133 may be formed on a side of the movable seat 130 facing the fixed seat 110. The fixed seat 110 is provided with a swing member 111 on a side facing the movable seat 130, and the swing member 111 can swing rotationally about a predetermined swing axis. For example, one end of the swinging member 111 may be rotatably connected to the fixing base 110, and the other end may be at least partially embedded in the sliding slot 133.

As shown in fig. 4, the swing member 111 may include a swing arm 1111 and a clamping post 1112, and one end of the swing arm 1111 may be rotatably connected to the fixing base 110 about a predetermined swing axis. The clamping column 1112 may be disposed at the other end of the swing arm 1111 and extends away from the fixing base 110. The clamping column 1112 is embedded in the chute 133. When the movable base 130 rotates relative to the fixed base 110, there is also a relative movement between the clamping post 1112 and the sliding slot 133 such that the clamping post 1112 can slide in the sliding slot 133 in a rotationally swinging state, that is, the swing arm 1111 can adapt to the sliding of the clamping post 1112 in the sliding slot 133 and can swing around a predetermined swing axis.

The chute 133 may be configured to allow the wire 20 to be stopped after the portion is pulled out, and to allow the wire 20 to be recovered into the holder 110 in a stopped state after the portion is pulled out. Which involves a two-way rotation of the movable mount 130. Specifically, when the wire 20 is in the pulled state, the movable base 130 can rotate in the first direction relative to the fixed base 110. When the wire 20 is in the recovered state, the movable base 130 can rotate relative to the fixed base 110 in a second direction opposite to the first direction. When the movable seat 130 rotates in the first direction or the second direction, the clamping column 1112 can adapt to the sliding in the sliding chute 133 and rotate and swing around the preset rotation axis 132; when the wire 20 is in a stopped state, the portion of the latch member embedded in the chute 133 can be locked in the chute 133, so as to stop the movable seat 130 from rotating in the second direction relative to the fixed seat 110.

There are a plurality of embodiments regarding the structure of the chute 133, and the following two embodiments are exemplified.

A first embodiment as shown in fig. 5:

the chute 133 includes a first annular groove 1331a, a second annular groove 1332a, a first guide groove 1333a, and a second guide groove 1334a. The first annular groove 1331a is provided around the periphery of the second annular groove 1332 a. The first and second guide grooves 1333a and 1334a are spaced apart and each communicate between the first and second annular grooves 1331a and 1332 a. Wherein, the clamping column 1112 is capable of sliding along at least one of the first annular groove 1331a and the second annular groove 1332a when the wire 20 is in the pulled state or the retracted state. The first guide groove 1333a is used for sliding the clamping column 1112 from the first annular groove 1331a into the second annular groove 1332a; when the wire 20 is in a stopped state, the clamping column 1112 can be clamped in the first guide slot 1333a; the second guide groove 1334a is used for sliding the clamping column 1112 from the second annular groove 1332a into the first annular groove 1331a. Optionally, a stop step 1335a is formed in the first guide groove 1333 a. When the wire 20 is in the drawing state and the clamping column 1112 is located in the first annular groove 1331a, the movable seat 130 rotates relative to the fixed seat 110 along the first direction, so that the clamping column 1112 slides along the first annular groove 1331 a; when the wire 20 is further switched from the pulled state to the recovered state, the clamping column 1112 can slide into the first guide slot 1333a from the first annular slot 1331a and be clamped in the stop step 1335a, and the movable seat 130 is limited to rotate continuously in the second direction, so that the wire 20 is stopped in the recovered state and is stopped.

A second embodiment as shown in fig. 6:

the chute 133 includes a first annular groove 1331b, a second annular groove 1332b, a middle groove 1336b, a first guide groove 1333b, a second guide groove 1334b, a third guide groove 1337b, and a fourth guide groove 1338b. The first annular groove 1331b is wound around the periphery of the second annular groove 1332b and the middle groove 1336b, and the middle groove 1336b is clamped between the first annular groove 1331b and the second annular groove 1332b; the first guide groove 1333b is communicated between the first annular groove 1331b and the second annular groove 1332b, the second guide groove 1334b is communicated between the first annular groove 1331b and the intermediate groove 1336b, and the third guide groove 1337b and the fourth guide groove 1338b are communicated between the second annular groove 1332b and the intermediate groove 1336b. Wherein, the clamping column 1112 is capable of sliding along at least one of the first annular groove 1331b, the second annular groove 1332b and the intermediate groove 1336b when the wire 20 is in the pulled state or the retracted state. The first guide groove 1333b is used for sliding the clamping column 1112 from the first annular groove 1331b into the second annular groove 1332b; the clamping column 1112 can be clamped in the first guide groove 1333b when the wire 20 is in a stopped state. The second guide groove 1334b is used for sliding the clamping post 1112 from the intermediate groove 1336b into the first annular groove 1331b. The third guide slot 1337b is used for sliding the clamping post 1112 from the second annular slot 1332b into the intermediate slot 1336b. The fourth guide groove 1338b is used for sliding the clamping post 1112 from the intermediate groove 1336b into the second annular groove 1332b.

Alternatively, a stopping step 1335b is formed in the first guide groove 1333 b; when the wire 20 is in the drawing state and the clamping column 1112 is located in the first annular groove 1331b, the movable seat 130 rotates relative to the fixed seat 110 along the first direction, so that the clamping column 1112 slides along the first annular groove 1331 b; when the wire 20 is further switched from the pulled state to the recovered state, the clamping column 1112 can slide into the first guide slot 1333b from the first annular slot 1331b and be clamped on the stop step 1335b, and the movable seat 130 is limited to rotate continuously in the second direction, so that the wire 20 is stopped in the recovered state and is stopped.

Of course, in addition to the above-mentioned two exemplary embodiments of the chute 133, the chute 133 may have a plurality of structural forms, which are not described herein, so long as the pulling, stopping and recycling of the wire 20 can be satisfied.

As described above, one end of the conductive wire 20 is fixed to the movable base 130 and electrically connected to the electrical connection assembly 200. For example, the electrical connection assembly 200 is disposed on one side of the movable base 130, and one end of the wire 20 may be inserted through the movable base 130 to connect with the electrical connection assembly 200 on one side of the movable base 130. The electrical connection assembly 200 is capable of adapting to the rotation of the wire 20 along with the movable base 130, so that the wire 20 is kept electrically connected with the electrical connection assembly 200. With respect to the electrical connection assembly 200 of the above-described embodiments, reference may be made to an electrical connection assembly 200 as exemplarily described below with respect to embodiments of the electrical connection assembly 200 of the present application.

As shown in fig. 2 and 3, the electrical connection assembly 200 may include a first electrical assembly 210 and a second electrical assembly 220. The first electrical component 210 and the second electrical component 220 are disposed opposite. The first electrical component 210 and the second electrical component 220 are capable of relative movement. For example, the relative movement between the first electrical component 210 and the second electrical connection is synchronized with the relative movement between the stationary seat 110 and the movable seat 130.

Alternatively, one of the first electrical component 210 and the second electrical component 220 is coupled to the bracket assembly 100, capable of relative movement with the bracket assembly 100 with respect to the other of the first electrical component 210 and the second electrical component 220. One of the first electrical component 210 and the second electrical component 220, which is connected to the bracket component 100, may be electrically connected to the conductive wire 20, while the other is connected to at least one first electrical interface 21. The first electrical component 210 and the second electrical component 220 are electrically connected, and the conductive wire 20 can be electrically connected to the electrical interface through the first electrical component 210 and the second electrical component 220.

The lead 20 is, for example, a data line or a charging line commonly used for electronic devices, but may be an electric wire used for daily electrical connection. The wire 20 may have a second electrical interface 22, such as Type-C, USB, etc., although other types of interfaces are possible. The first electrical interface 21 may be a Type-C, USB interface, a charging electrode plug, or other types of interfaces. Thus, the wire storage device 10 can have different functions, such as interface switching function, data transmission function, charging function, etc., by matching with different interfaces.

Alternatively, one of the first electrical component 210 and the second electrical component 220 is fixedly disposed on the movable base 130, and the other electrical component may be relatively fixed to the fixed base 110. In the present embodiment, the second electrical component 220 may be fixedly connected to a side of the movable base 130 facing away from the fixed base 110, and the first electrical component 210 may be fixedly connected to the mounting base 120, i.e. relatively fixed to the fixed base 110. During the relative movement of the fixed base 110 and the movable base 130, the first electrical component 210 and the second electrical component 220 also move relatively.

As shown in fig. 7, the first electrical component 210 includes a first connection plate 212. For example, the first connection board 212 may be a PCB circuit board. For example, the first connecting plate 212 may be disc-shaped, and has a circular hole with a preset axis as an axis, so that the rotating shaft 132 of the movable seat 130 is sleeved with the circular hole to be fixed on the movable seat 130. Optionally, the first electrical component 210 includes a spring seat 213. The spring plate seat 213 may be used for fixedly connecting the spring plate 211. The spring plate seat 213 may be fixedly disposed on the first connecting plate 212.

As shown in fig. 8, the second electrical assembly 220 includes a second connection plate 222. Alternatively, the second connection board 222 may be a PCB circuit board. Alternatively, the second connecting plate 222 may also be provided in a disc shape. The first connection plate 212 and the second connection plate 222 may be disposed opposite to each other. The connection electrode 221 is disposed on the second connection plate 222. Alternatively, the connection electrode 221 is disposed at a side of the second connection plate 222 facing the first connection plate 212. Alternatively, the connection electrode 221 may be integrated with a wiring on the second connection plate 222. Alternatively, the connection electrode 221 may be disposed in a ring shape around a preset axis.

As shown in fig. 7 and 8, the first electrical component 210 may be provided with a connection spring 211. Alternatively, the connecting spring 211 may be fixed to the spring seat 213. The second electrical component 220 electrical connection component 200 may be provided with connection electrodes 221 contacting the connection spring pieces 211. Specifically, the connection spring piece 211 is located at a side of the first electrical component 210 facing the second electrical component 220, and the connection electrode 221 is located at a side of the second electrical component 220 facing the first electrical component 210, and the connection spring piece 211 and the connection electrode 221 are kept in contact during the relative movement of the first electrical component 210 and the second electrical component 220.

As shown in fig. 7, the number of the connection spring pieces 211 may be plural, for example, 2 to 10, for example, 4 to 8. The plurality of connecting spring plates 211 are arranged at intervals. Alternatively, the plurality of connection clips 211 may be divided into two groups. Each set of connecting clips 211 includes at least one connecting clip 211. Each set of connecting spring plates 211 may be disposed on one spring plate seat 213. The two sets of connecting elastic pieces 211 are located at two sides of the preset axis, for example, a connecting line between the two sets of connecting elastic pieces 211 passes through the preset axis, and the preset axis is located in the middle of the connecting line. Optionally, the connecting spring piece 211 may be further coated with a gold plating layer (not shown), so as to improve wear resistance.

As shown in fig. 8, the number of the connection electrodes 221 is correspondingly plural, and the connection electrodes 221 are disposed at intervals (i.e. substantially in a multi-ring nested manner) along a radial direction perpendicular to the preset axis (i.e. the rotation axis of the movable base 130), and are disposed one by one with the connection elastic pieces 211.

As shown in fig. 9, the connection spring piece 211 may have a circular arc segment 2111 that arches toward the connection electrode 221. Specifically, the connection elastic piece 211 includes a fixing segment 2112 and a circular arc segment 2111 that meet in the extending direction of the connection elastic piece 211. For example, the connection spring 211 is a sheet-like member, and may include a fixing segment 2112 and a circular arc segment 2111 adjacently connected in the extending direction thereof. For example, the fixing segment 2112 is located at one end of the connecting elastic piece 211, and arches in the direction of the other end to form an arc segment 2111.

In this embodiment, the arc segment 2111 may mean that the segment is arc-shaped like a sheet, and the arc is arched toward the connection electrode 221. In this manner, the arc segments 2111 may contact the connection electrode 221, and the arc segments may remain in elastic abutment with the connection electrode 221 during the relative movement of the first and second electrical components 210, 220, such that the first and second electrical components 210, 220 are electrically connected.

By arranging the connecting elastic sheet 211 to have the arc segment 2111 arched towards the connecting electrode 221, the arched surface of the arc segment 2111 is smooth due to the arc characteristic, and when the connecting elastic sheet moves relatively to the connecting electrode 221 and keeps contact with the connecting electrode 221, the friction resistance between the connecting elastic sheet and the connecting electrode 221 can be effectively reduced, so that the relative movement of the connecting elastic sheet and the connecting electrode is smoother, and the contact between the connecting electrode and the connecting electrode is more stable. Moreover, the elasticity of the arc segment 2111 of the connection spring 211 can make the contact between the connection spring 211 and the connection electrode 221 more stable, and thus the stability of electrical connection can be improved.

Specifically, the fixation segment 2112 is fixed to the first connection plate 212. For example, the fixing segment 2112 may be directly fixed to the first connection plate 212, or other devices may be added to fix the fixing segment 2112 to the other devices. The arc segment 2111 extends and curves in a direction away from the fixing segment 2112, and arcs toward the connection electrode 221. The arc segment 2111 is suspended away from the end of the fixing segment 2112, so that the connecting spring 211 can elastically float. In other words, when the arc segment 2111 is pressed by the connection electrode 221, the arc segment 2111 can rotate about the fixing segment 2112 to generate corresponding elastic deformation, and the arc of the arc segment 2111 can also be changed along with the pressing, so that corresponding elastic deformation can be generated, and the arc segment 2111 can be better contacted with the fixing segment 2112.

Further, the fixing segment 2112 may be fixedly connected to the spring plate seat 213. The arc segment 2111 arches outward toward one side of the dome base 213. Through setting up shell fragment seat 213 can increase and connect shell fragment 211, and then make and connect shell fragment 211 and can be closer to second electrical component 220, and then can increase the butt dynamics between connection shell fragment 211 and the connection electrode 221, improve electrical connection's stability.

The fixing segment 2112 may be provided on the top of the dome base 213 (i.e., toward the side of the second electrical component 220). Of course, the spring plate seat 213 may also be provided with a corresponding structure fixedly connected to the fixing segment 2112. As shown in fig. 9 and 10, the top of the spring plate seat 213 away from the first connection plate 212 may be provided with a receiving groove 2130 extending through to a side edge thereof. The receiving groove 2130 may be recessed from the top toward the bottom of the spring plate seat 213, and the recessed space may also extend laterally to the side edge of the spring plate seat 213. Specifically, the spring plate seat 213 is provided with a bearing platform 2131 lower than the top in the accommodation area. The lower base 2131 is lower than the top, which means that the base 2131 is lower than the top in the height direction of the spring plate base 213 (i.e., the direction from the first electrical component 210 to the second electrical component 220). Specifically, the fixing segment 2112 may be fixedly connected to the base 2131, with the arc segment 2111 arching in a top direction, and with the arc segment 2111 at least partially outside the receiving groove 2130, and with the arc segment 2111 extending away from the end of the fixing segment 2112 in an edge direction and outside the receiving groove 2130. In this way, the portion of the arc segment 2111 located outside the accommodation groove 2130 can abut against the connection electrode 221, improving the stability of electrical connection.

Alternatively, the spring plate seat 213 may be provided with the same number of receiving slots 2130 as the number of the connecting spring plates 211, and each receiving slot 2130 corresponds to a receiving one of the connecting spring plates 211. The circular arc segments 2111 may remain in resilient abutment with the connection electrode 221 during relative rotation of the first electrical component 210 and the second electrical component 220. Optionally, the arc segment 2111 is tangential to the connecting electrode 221. Alternatively, the arc top tangent of the arc segment 2111 is parallel to the tangent of the outer ring edge of the corresponding connection electrode 221. Therefore, the two can be smoother in the relative motion process, and the friction force is further reduced.

Alternatively, as shown in fig. 9, the height H1 of the arc segment 2111 outside the accommodation groove 2130 may be 0.8 to 1.2cm. Alternatively, the height H1 of the arc segment 2111 outside the accommodation groove 2130 may be 0.9 to 1cm, alternatively, the height H1 of the arc segment 2111 outside the accommodation groove 2130 may be 1.05±0.15.

Alternatively, as shown in fig. 9, the height difference H2 between the above-described end and the bottom surface of the accommodation groove 2130 may be 1.5 to 2cm. The bottom surface of the accommodation groove 2130 is a bottom surface of the accommodation groove 2130 corresponding to the distal end (the bottom surface to which the distal end can be contacted after being pressed). Since there may be a height difference at the bottom of the accommodation groove 2130, the bottom surface of the accommodation groove 2130 refers to the bottom surface corresponding to the tip. Alternatively, the height difference H2 between the above-described end and the bottom surface of the accommodation groove 2130 may be 1.6 to 1.8cm.
