Description

Horizontal bending electrostatic protection module

The present invention relates to an electrostatic protection module, and more particularly to a horizontally bent electrostatic protection module.

In the prior art, in order to prevent the electronic device from being damaged due to the static electricity on the user's body being conducted to the electronic device when the user is operating the electronic device, an anti-static design is usually added to the electronic device.

Please refer to the first and second figures. The first figure is a three-dimensional exploded schematic diagram showing the conductive foam of the prior art being arranged on the inner side of the server case; the second figure is a three-dimensional schematic diagram showing the server case of the prior art being used for installing electronic components. As shown in the first and second figures, in order to prevent the electronic components installed in the server case PA1 from being damaged, in the prior art, a conductive foam PA2 is attached to the inner side of the side bracket PA11 of the server case PA1, so that when the tray module PA3 equipped with the electronic components enters the server case PA1, the tray module PA3 can be grounded to the server case PA1 by contacting the conductive foam PA2. At this time, even if the static electricity on the user's body is transmitted to the tray module PA3, the static electricity will be transmitted to the server case PA1 through the conductive foam PA2.

As mentioned above, although in the prior art, the tray module PA3 can be grounded to the server case PA1 through the conductive foam PA2, since the existing conductive foam PA2 is mainly fixed to the inner side of the side bracket PA11 by gluing, although the conductive foam PA2 can allow the tray module PA3 to be grounded to the server case PA1, when the tray module PA3 enters the server case PA1, the conductive foam PA2 is easily pushed off by the tray module PA3 due to the unreliable fixing method, resulting in the anti-static design failing to function normally.

In view of the prior art, in order to prevent static electricity from entering the internal electronic components and causing damage when loading and unloading the tray module, a conductive foam is usually set on the inner side of the side bracket so that the tray module can be grounded to the server case by contacting the conductive foam. However, since the conductive foam is generally only fixed by gluing, when the tray module enters the server case, the conductive foam is easily pushed off by the tray module, resulting in the tray module being unable to be accurately grounded to the server case. Therefore, the main purpose of the present invention is to provide a horizontally bent static protection module that can solve the problem of the conductive foam being easily squeezed off by the tray module.

The present invention solves the problems of the prior art by adopting a necessary technical means of providing a horizontally folding electrostatic protection module for assembly on a side frame of a device housing. The side frame has an inner side surface and an outer side surface which are arranged opposite to each other, and the side frame is provided with a lock hole penetrating the inner side surface and the outer side surface. The horizontally folding electrostatic protection module includes a conductive cloth and an elastic conductor.

The conductive cloth includes a protruding structure, a flat fixing portion and a folded fixing portion. The protruding structure has a first connecting end and a second connecting end that are arranged opposite to each other, and a containing space is formed between the first connecting end and the second connecting end. The flat fixing portion is connected to one end of the protruding structure for being attached to the inner side surface. The folded fixing portion is connected to the other end of the protruding structure opposite to the flat fixing portion for being attached to the outer side surface, and the folded fixing portion is provided with a groove, and the groove is aligned with the lock hole when the folded fixing portion is attached to the outer side surface, so as to allow a locking element to lock the folded fixing portion to the lock hole. The elastic conductive body is fixed in the accommodating space, and abuts against the inner side surface when the flat fixing portion and the folded fixing portion are fixed to the side frame.

In an auxiliary technical means derived from the above-mentioned necessary technical means, the protrusion structure further includes a contact section, a first guide section and a second guide section, the contact section extends along a first direction, the first guide section extends from one end of the contact section along a first inclined direction different from the first direction to form the first connecting end, and the second guide section extends from the other end of the contact section relative to the first guide section along a second inclined direction inclined to the first direction to form the second connecting end.

Preferably, there is a first angle between the first guide section and the flat fixing portion, and there is a second angle between the second guide section and the flat fixing portion, the first angle is between 120° and 150°, and the second angle is between 30° and 60°.

In an auxiliary technical means derived from the above necessary technical means, the elastic conductor is a conductive foam.

The present invention mainly combines an elastic conductor with a conductive cloth, and then fixes the folded fixing portion of the conductive cloth by locking, and fixes the flat fixing portion by gluing, so as to fix the elastic conductor to the side frame of the device casing, effectively preventing the horizontal folding electrostatic protection module from being squeezed by the electronic components when the electronic components are loaded and unloaded, thereby allowing the electronic components to be grounded to the device casing reliably.

The specific embodiments of the present invention will be further described by the following embodiments and drawings.

As shown in FIGS. 3 to 5 , a horizontally foldable electrostatic protection module 100 includes a conductive fabric 1 and an elastic conductor 2 .

The conductive fabric 1 comprises a protruding structure 11, a flat fixing portion 12 and a folded fixing portion 13. The conductive fabric 1 of this embodiment is a woven fabric with a conductive function.

The protruding structure 11 includes a contact section 111, a first guide section 112 and a second guide section 113. The contact section 111 extends along a first direction D1. The first guide section 112 extends from one end of the contact section 111 along a first inclined direction D2 different from the first direction D1 and forms a first connecting end 1121. The second guide section 113 extends from the other end of the contact section 111 opposite to the first guide section 112 along a second inclined direction D3 inclined to the first direction D1 and forms a second connecting end 1131.

As described above, the first guiding section 112 and the second guiding section 113 extend from two ends of the contact section 111 along the first inclined direction D2 and the second inclined direction D3 respectively, so that the protruding structure 11 further forms an accommodating space S1 between the first connecting end 1121 and the second connecting end 1131 .

The flat fixing portion 12 is integrally connected to the first connecting end 1121, and the folded fixing portion 13 is integrally connected to the second connecting end 1131. When actually used, the flat fixing portion 12 extends along the first direction D1, and the folded fixing portion 13 is first bent and then extends along the first direction D1. In addition, the folded fixing portion 13 is further provided with a groove 131.

The elastic conductive body 2 is fixed in the accommodation space S1, and abuts against the inner side surface when the flat fixing portion 12 and the folded fixing portion 13 are fixed to the side frame. The elastic conductive body 2 is connected to the abutting section 111, the first guiding section 112 and the second guiding section 113 by, for example, conductive glue, but not limited thereto, and can also be connected to the abutting section 111, the first guiding section 112 and the second guiding section 113 by welding, or by using a general adhesive method to connect to the abutting section 111, the first guiding section 112 and the second guiding section 113. Partial areas, so that the unconnected portion can still directly contact at least one of the abutting section 111, the first guiding section 112 and the second guiding section 113, so that the elastic conductive body 2 is electrically connected to the protruding structure 11.

In addition, the elastic conductor 2 of the present embodiment is actually a conductive foam. Specifically, the elastic conductor 2 is a foam structure doped with a conductive material, and the composition of the foam structure can be a high molecular polymer such as PE, PP, PU, EVA, SBR or EPDM.

Please continue to refer to the sixth figure, which is a schematic plan view of the horizontal bending type electrostatic protection module of the present invention in actual use. As shown in the fifth and sixth figures, there is a first angle R1 between the first guide section 112 and the flat fixing portion 12, and there is a second angle R2 between the second guide section 113 and the flat fixing portion 12; wherein, the first angle R1 is 135°, and the second angle R2 is 45°, but not limited thereto, the first angle R1 can be between 120° and 150°, and the second angle R2 can be between 30° and 60°.

Please continue to refer to Figures 7 and 8. Figure 7 is a three-dimensional exploded schematic diagram showing the horizontal folding electrostatic protection module of the present invention installed on the device casing; Figure 8 is a three-dimensional schematic diagram showing the horizontal folding electrostatic protection module of the present invention installed on the device casing, so that the electronic components can be grounded to the device casing when the electronic components enter the device casing.

As shown in FIGS. 5 to 8, when a user wants to install the horizontal folding electrostatic protection module 100 on a side frame 201 of a device housing 200, since the side frame 201 has an outer side surface 2011 and an inner side surface 2012 disposed opposite to each other, and the side frame 201 is also provided with a lock hole 2013 penetrating the outer side surface 2011 and the inner side surface 2012, the user can first fit the folded fixing portion 13 to the outer side surface 2011 and the inner side surface 2012. 11, and align the groove 131 with the locking hole 2013, and then use a locking element 300 to lock the inverted fixing portion 13 to the locking hole 2013, so that the inverted fixing portion 13 is fixed to the side frame 201; wherein, during actual use, the locking element 300 is further used to lock an ear frame 202 to the locking hole 2013 of the side frame 201, so that the inverted fixing portion 13 will actually be locked between the side frame 201 and the ear frame 202.

On the other hand, the flat fixing portion 12 is used to be fixed to the inner side surface 2012 of the side frame 201, so that the entire horizontal bending type electrostatic protection module 100 is fixed to the side frame 201. The device housing 200 of this embodiment is, for example, a server housing, but is not limited thereto.

As described above, when the horizontal bending type electrostatic protection module 100 is fixed to the side frame 201, the elastic conductor 2 will abut against the inner side surface 2012, so that the horizontal bending type electrostatic protection module 100 is grounded to the device housing 200; thereby, when an electronic component 400 enters the device housing 200 along the first direction D1, the electronic component 400 will first be pushed to the first side surface 2012. The two guide sections 113 cause the protruding structure 11 to be deformed due to being squeezed. At this time, the elastic conductor 2 between the protruding structure 11 and the side frame 201 will be compressed and deformed, so that the protruding structure 11 continues to abut the electronic component 400, so that the electronic component 400 can be grounded to the device housing 200 through the conductive cloth 1 and the elastic conductor 2.

Specifically, the electronic component 400 is, for example, a tray module provided with various electronic components. Therefore, when the user pushes the electronic component 400 into the device case 200, it can be grounded to the device case 200 through the horizontally folding electrostatic protection module 100. In particular, since the horizontally folding electrostatic protection module 100 provided in this embodiment has a second guide section 113, and the second guide section 113 is along a second inclined direction D3 inclined to the first direction D1. Therefore, when the second guide section 113 is pushed by the electronic component 400, the elastic conductor 2 can be gradually squeezed. Moreover, since the horizontally folding electrostatic protection module 100 of this embodiment fixes the folded fixing portion 13 to the side frame 201 in a locking manner, it can more effectively prevent the entire horizontally folding electrostatic protection module 100 from falling off due to the pushing of the electronic component 400, thereby effectively keeping the electronic component 400 grounded to the device casing 200.

On the other hand, when the electronic component 400 is pulled out from the device housing 200 in the opposite direction of the first direction D1, the first guide section 112 can also be used to guide and cushion the pushing force of the electronic component 400, thereby preventing the horizontal bending type electrostatic protection module 100 from falling off.

In summary, compared to the conductive foam of the prior art, which is only fixed to the server case by a simple pasting method and is therefore easily removed by the pushing of the tray, the horizontal folding electrostatic protection module of the present invention mainly combines an elastic conductor with a conductive cloth, and then fixes the folded fixing portion of the conductive cloth by locking, and fixes the flat fixing portion by pasting, so that the elastic conductor can be effectively fixed to the side frame of the device case, and the elastic conductor is electrically connected to the side frame, thereby effectively preventing the horizontal folding electrostatic protection module from being squeezed by the electronic components, and thus allowing the electronic components to be grounded to the device case.

The horizontally foldable electrostatic protection module provided by the preferred embodiment of the present invention can be installed in, for example, a server host, which can be used for artificial intelligence (AI) computing, edge computing, etc., and can also be used as a 5G server, cloud server or car networking server.
