Description

Wire protection chain

technical field

The invention relates to a carrying structure of an electronic device, and in particular to a device for protecting and storing electric wires.

Background technique

Generally speaking, multiple electronic devices such as hard disks, optical drives, processors or fans are usually loaded in a large computer. In order to facilitate assembly, a connector is usually installed at the installation position of the machine, and the connector is electrically connected to the power supply, and the electronic device can obtain power after being connected to the connector. On the other hand, the electronic device can also be electrically connected to the circuit board in the machine through the connector.

At present, most common machines adopt a hot-swap design structure, which means that the connection between the connector and the power supply adopts a re-swappable design. Taking a rack server as an example, the machine platform of the rack server has a casing and a cabinet like a drawer, and the cabinet is equipped with connectors. In the hot-swappable design, when the box is pulled out of the case, the connection between the connector and the power supply is immediately separated, so the electronic power supply and connection are also interrupted.

However, sometimes the user pulls out the box just to check whether the electronic device is working normally, not to disassemble the electronic device. Every time the box is pulled out, the connection of the electronic device is interrupted, which not only interrupts the calculation and processing action, delays the calculation time, but also damages the electronic device due to repeated power cuts.

To solve the above problems, the most intuitive way is to connect the connector to the power supply or the circuit board with bendable wires. Since the wires can be stretched by straightening or shortened by bending, the connection between the connector and the power supply or the circuit board will not be separated when the box is drawn out, so that the power supply and connection of the electronic device will not be interrupted.

The length of the wires must allow the entire box to be pulled completely out of the enclosure. Due to the long length of the wires, when the box is pushed into the case, the way and position of the wires cannot be folded as expected, and sometimes the box may be stuck so that the box cannot be pushed into the case, or Crush into surrounding electronic components, or tangle with other wires.

In view of this, there is a need for a pulling device and its wire protection device, which can be used to limit the travel of wires such as electric wires, so that the wires can only be straightened in a predetermined way or folded in a predetermined position.

Contents of the invention

The technical problem to be solved by the present invention is to provide a wire protection chain, which is used to limit the bending or elongation of the wire, so as to limit the position of the wire during the bending or elongation process.

Another object of the present invention is to provide a wire protection chain that can be folded in a predetermined position along a predetermined folding path.

In order to achieve the above object, the present invention provides a wire protection chain, which has several forward segments and several reverse segments that are interlaced and linked. There are several forward chain monomers linked to each other in each forward segment. Wherein, the angle between each forward chain monomer relative to the forward chain monomer to which it is linked is limited to be between 0 degrees and 180 degrees. In other words, each directional chain cell can only deflect clockwise relative to the directional chain cell to which it is linked.

There are several reverse chain monomers linked to each other in each reverse segment. Wherein, the included angle of each reverse chain monomer relative to the reverse chain monomer to which it is linked is limited to be between 180 degrees and 360 degrees. Note that included angles are expressed in terms of vector angles. It can be seen from this that each reverse chain monomer can only deflect counterclockwise relative to the linked reverse chain monomer.

Through the staggered arrangement of forward segments and reverse segments, the wire protection chain can be folded in a zigzag shape. In this way, not only can the freedom of folding the wire protection chain be limited, but also the folded wire protection chain can be limited to a specific area, further preventing the wire from being stuck or squeezed by surrounding electronic devices, or entangled with other wires, etc. question.

In order to achieve the above object, the present invention also provides a wire protection chain, which contains several forward chain monomers and several reverse chain monomers. The forward chain monomers link with each other to form multiple forward segments. Among them, the angle between each forward chain monomer relative to the linked forward chain monomer is limited to between 0 degrees and 180 degrees, that is, any two linked forward chain monomers can only move clockwise direction deflection.

The monomers of the reverse chain link to each other to form an extended segment and several reverse segments. One end of the extension is connected to one of the forward segments. The reverse segment and the forward segment are arranged alternately with each other.

The angle between each reverse chain monomer relative to the linked reverse chain monomer is limited to 180° to 360°, that is, the two linked reverse chain monomers can only be deflected in the counterclockwise direction.

Through the arrangement of forward chain monomers and reverse chain monomers, the wire protection chain will fold back and forth in a zigzag shape due to the bending of the forward segment and the reverse segment during the bending and folding process, so as to limit the wire protection The degree of freedom of chain folding allows it to be bent and folded only in a predetermined direction, thereby limiting the position of the folded wire protection chain.

Detailed ways

Please refer to FIG. 1A and FIG. 1B at the same time. 1A and 1B are perspective and side views, respectively, of a directional segment 104 of an embodiment of the present invention. The forward segment 104 is basically formed by linking a plurality of forward chain monomers 108 . Please note that there are many types of forward chain monomers 108, and the linking methods are also different. Here, a type of forward chain monomer 108 is provided as an illustration, but the type of forward chain monomer 108 is not limited.

In the embodiment of the present invention, each forward chain monomer 108 has a through hole 110, and the two openings of the through hole 110 are respectively provided with a hole 112 and a shaft 114, the size and position of the hole 112 are matched with the shaft 114 To socket the shaft 114 . By fitting the hole 112 of one forward chain unit 108 onto the shaft 114 of the other forward chain unit 108 , the two forward chain units 108 are pivotally connected to each other and linked together.

The forward chain unit 108 can rotate relative to the linked forward chain unit 108 in the clockwise direction 200 with the shaft 114 as the axis. Wherein, the included angle of each forward chain monomer 108 relative to another linked forward chain monomer 108 is the first angle a1. The first angle a1 is limited to be between 0 degrees and 180 degrees. Preferably, the first angle a1 is between 60 degrees and 180 degrees. In an embodiment of the present invention, the first angle a1 is less than 180 degrees and greater than 90 degrees. Please note that the first angle a1 is expressed as a vector angle.

In other words, except for the forward chain monomers 108 that are linked in parallel, the forward chain monomers 108 can only use the axis 114 as the axis to move along the clockwise direction 200 relative to the forward direction to which the axis 114 is linked. The chain monomer 108 is deflected and cannot be reversed.

In order to achieve the limitation of one-way rotation, the forward chain unit 108 is provided with a stopper assembly that blocks reverse deflection. Those with ordinary knowledge in the technical field of the present invention should be familiar with various possible structures to achieve the limitation of one-way rotation, and details will not be repeated here. In the embodiment of the present invention, the two open ends of the through hole 110 of the forward chain monomer 108 are respectively provided with a first stopper 116 and a second stopper 118 . The first stopper 116 is like a protrusion, located on the path of the second stopper 118 along with the counterclockwise rotation of the chain unit 108 . When the forward chain unit 108 intends to rotate counterclockwise so that the first angle a1 is greater than 180 degrees, the first stopper 116 will abut against the second stopper 118 so that the forward chain unit 108 cannot reversely deflect.

On the other hand, after the forward chain monomers 108 are connected with each other, the through holes 110 thereof are opposite to each other, and then connected in series to form a continuous channel like a tube, which can be used for accommodating wires.

Please refer to FIG. 2A and FIG. 2B at the same time. 2A and 2B are perspective and side views, respectively, of the reverse segment 106 .

The reverse segment 106 is mainly formed by connecting several reverse chain monomers 109 to each other. In the embodiment of the present invention, each reverse chain monomer 109 has a through hole 110, and the two openings of the through hole 110 are respectively provided with a hole 112 and a shaft 114, the size and position of the hole 112 are matched with the shaft 114 to cover The connecting shaft 114 is connected to the shaft 114 of the other reverse chain unit 109 through the hole 112 of one reverse chain unit 109 , so that the two reverse chain units 109 are pivotally connected to each other and linked together.

The reverse chain unit 109 can rotate relative to the linked reverse chain unit 109 along the counterclockwise direction 210 with the axis 114 as the axis. Specifically, there is a second angle a2 between each reverse chain monomer 109 and another linked reverse chain monomer 109, and the second angle a2 is limited between 180 degrees and 360 degrees. Preferably, the second angle a2 is greater than 180 degrees and less than 300 degrees. In an embodiment of the present invention, the second angle a2 is between 180 degrees and 270 degrees. Please note that the second angle a2 is expressed as a vector angle.

In other words, except for the reverse chain monomers 109 that are linked in parallel, the reverse chain monomers 109 can only deflect in the counterclockwise direction 210 relative to the reverse chain monomers 108 that are linked with the axis 114 provided thereon. , but cannot reverse the forward deflection.

As mentioned above, in order to achieve the limitation of rotation only in the counterclockwise direction 210 , the reverse chain unit 109 is also provided with a first stopper 116 and a second stopper 118 that block forward deflection. Specifically, the first stopper 116 and the second stopper 118 are respectively disposed at two open ends of the through hole 110 of the reverse chain unit 109 . The first stopper 116 is like a protrusion, and is disposed on the path where the second stopper 118 rotates with the reverse chain unit 109 . When the reverse chain unit 109 is going to rotate clockwise, the first stopper 116 will be against the second stopper 118 of the connected reverse chain unit 109 , so that the reverse chain unit 109 cannot rotate.

On the other hand, the through holes 110 of the reverse chain monomers 109 are opposite to the through holes 110 of other reverse chain monomers 109 , so that the through holes 110 of the linked reverse chain monomers 109 can form a continuous channel. Continuous channels are available for loading wire.

Please refer to FIG. 3 , which is a wire protection chain 100 according to an embodiment of the present invention. The wire protection chain 100 has several forward segments 104 and several reverse segments 106, and the forward segments 104 and the reverse segments 106 are arranged alternately and linked. As mentioned above, because the forward segment 104 can only bend clockwise and the reverse segment 106 can only bend counterclockwise, so when the wire protection chain 100 is pushed to bend and shrink, the staggered forward segment 104 and reverse segment 106 will make the wire protection The chain 100 is folded back and forth like a zigzag.

When the forward segment 104 is connected to the reverse segment 106, the through hole 110 of the forward chain monomer 108 in the forward segment 104 will be opposite to the through hole 110 of the reverse chain monomer 109 in the reverse segment 106, thereby forming a continuous channel . Users can place wires such as wires 120 in the continuous channel to protect the wires.

In the embodiment of the present invention, the wire protection chain 100 is also provided with an extension section 102, which can be used by the user to extend the total length of the wire protection chain 100 after extension, and the wiring can also be adjusted according to the designer's design requirements. hole position.

The extension section 102 can be composed of two-way rotatable chain monomers, or can be formed by interconnecting unidirectional chain monomers that can only rotate in one direction. The unidirectional chain monomer can be forward chain monomer 108 or reverse chain monomer 109 . Both the forward chain monomer 108 and the reverse chain monomer 109 have been described in detail in the above-mentioned articles, so no more details are given here. In the embodiment of the present invention, the extension section 102 is formed by connecting several reverse chain monomers 109 to each other.

The number of linked unidirectional chain monomers such as reverse chain monomers 109 in the extension section 102 is greater than the ratio of the number of forward chain monomers 108 in a single forward segment 104 to the number of reverse chain monomers 109 in a single reverse segment 106 sum. In this way, the length of the extension section 102 is greater than the sum of the lengths of a forward section 104 and a reverse section 106 .

In an embodiment of the present invention, the number of reverse chain monomers 109 in the extension section 102 is greater than the sum of the number of forward chain monomers 108 in all forward sections 104 and the number of reverse chain monomers 109 in all reverse sections 106 . In other words, in the embodiment of the present invention, the length of the extension section 102 is greater than the sum of the lengths of all forward sections 104 and reverse sections 106 .

In addition, when the extension section 102, the forward section 104 and the reverse section 106 are connected, the through holes 110 of the forward chain monomer 108 and the reverse chain monomer 109 will also face each other and form a continuous channel in series to accommodate the electric wire 120 in it.

In an embodiment of the present invention, one end of the extension section 102 is connected to one end of the forward section 104 , and the forward section 104 and the reverse section 106 are arranged in a staggered manner and linked. In other words, the starting point of the integral wire protection chain 100 is one end of the extension section 102 . In consideration of the wiring position and length, the last section of the wire protection chain 100 can be the reverse section 106 or the forward section 104 .

As mentioned above, the bending angle of the forward chain monomer 108 or the reverse chain monomer 109 in the embodiment of the invention is between 90 degrees and 180 degrees. Therefore, at least three forward chain monomers 108 or reverse chain monomers 109 are required to complete a 180-degree bend. It can be seen from this that the number of forward chain monomers 108 linked in each forward segment 104 should be greater than or equal to three. Moreover, the number of reverse chain monomers 109 linked in each reverse segment 106 should be greater than or equal to three. Since the quantity of the reverse chain monomer 109 in the extension section 102 is greater than the sum of the quantity sum of the reverse chain monomer 109 of the reverse section 106 and the forward chain monomer 108 of the forward section 104, the quantity of the reverse chain monomer 109 in the extension section 102 Must be greater than 6.

However, if the number of forward chain monomers 108 in each forward segment 104 is too much such as more than 6, the forward segment 104 may form a 360-degree bend during the bending process, which may hinder The other forward segment 104 or reverse segment 106 bends. Therefore, in the embodiment of the present invention, the number of forward chain monomers 108 linked in each forward segment 104 should be less than or equal to six. Similarly, the number of reverse chain monomers 109 in each reverse segment 106 should also be less than or equal to 6.

In an embodiment of the invention, the wires 120 are housed in a continuous channel. In detail, the electric wires 120 pass through the through holes 110 of each forward chain monomer 108 and reverse chain monomer 109 in the wire protection chain 100 . Moreover, one end of the wire 120 passes through and is fixed to one end of the extension section 102 to connect to an external electronic component such as a power supply or a circuit board. The other end of the wire 120 passes through the other end of the wire protection chain 100 to be connected to another electronic component.

It can be seen from the above-mentioned embodiments that the wire protection chain 100 disclosed in the present invention can not only protect the wire 120 from external impact or pulling, but also limit the degree of freedom of the bending and folding angle of the wire protection chain 100, so that the wire 120 can only Fold according to the predetermined bending direction of the wire protection chain 100 . In this way, problems such as the wire 120 being stuck or squeezed into peripheral electronic devices or entangled with other wires can be avoided.

Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. , so the protection scope of the present invention should be determined by the scope defined in the claims.
