Description

Technical Field

[0001] The present invention relates to a connecting member and a chassis, and particularly to a connecting member and a chassis with a relatively small volume. Background Art

[0002] Traditional chassis include a cover body, a box body and wires. The wires are used to connect the electronic components in the cover body and the electronic components in the box body. However, when the chassis is in an open state, the wires of the chassis are usually exposed, which makes the wires at risk of being scratched and broken, resulting in poor safety of the chassis and an unattractive overall appearance of the chassis.

[0003] Therefore, how to develop a connecting member and a chassis that overcome the above disadvantages is an urgent need at present. Summary of the Invention

[0004] The object of the present invention is to provide a connecting member and a chassis. The connecting member includes a first sub-connecting member, a second sub-connecting member and a plurality of shrinkable connecting members, so that each wire can be covered by the connecting member and not exposed, thereby achieving the effects of protecting the wires and organizing the wires, and beautifying the appearance of the chassis. In addition, when the chassis is in a closed state, the connecting member can be disposed in the slide rail of the previous sub-connecting member by using the protrusion of each sub-connecting member, and each sub-connecting member is received in the accommodating space of the previous sub-connecting member, so as to reduce the installation space of the connecting member, and further reduce the volume of the overall chassis.

[0005] To achieve the above object, an embodiment of the present invention is a connecting member pivotally connected between a box body and a cover body, and the connecting member includes a first sub-connecting member, a second sub-connecting member, and a plurality of retractable connecting members. The first sub-connecting member is disposed on the box body and includes three side walls and a first connecting member accommodating space formed by the three side walls. At least one side wall of the first sub-connecting member includes a slide rail that penetrates the side wall. The second sub-connecting member is disposed on the cover body and includes three side walls and a second connecting member accommodating space formed by the three side walls. The outer surface of at least one side wall of the second sub-connecting member includes a protrusion. The plurality of retractable connecting members are sequentially disposed between the first sub-connecting member and the second sub-connecting member. Each retractable connecting member includes three side walls and a third connecting member accommodating space formed by the three side walls. At least one side wall of each retractable connecting member includes a slide rail and a protrusion. The slide rail penetrates the side wall, and the protrusion is located on the outer surface of the side wall. The protrusion of the first retractable connecting member among the plurality of retractable connecting members is slidably disposed on the slide rail of the first sub-connecting member, so that the first retractable connecting member among the plurality of retractable connecting members can be received in the first connecting member accommodating space. The protrusions of the other retractable connecting members among the plurality of retractable connecting members are slidably disposed on the slide rails of the previous retractable connecting member, so that the other retractable connecting members among the plurality of retractable connecting members can be received in the third connecting member accommodating space of the previous retractable connecting member. The protrusion of the second sub-connecting member is slidably disposed on the slide rail of the last retractable connecting member, so that the second sub-connecting member is received in the third connecting member accommodating space of the last retractable connecting member.

[0006] To achieve the above object, another embodiment of the present invention is a chassis, including at least one wire and the aforementioned connecting member, wherein the connecting member covers at least one wire.

[0007] The beneficial effect of the present invention is that the connecting member of the chassis of the present invention includes a first sub-connecting member, a second sub-connecting member, and a plurality of retractable connecting members, so that each wire can be covered by the connecting member without being exposed, and the effects of protecting the wire and organizing the wire can be achieved simultaneously, and the appearance of the chassis can be beautified.
