[0044] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this specification. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this specification as detailed in the appended claims.

[0045] The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this specification. The singular forms “a,” “the,” and “the” as used in this specification and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0046] It should be understood that although the terms first, second, third, etc., may be used in this specification to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this specification, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0047] This application provides a sub-board substrate 100, such as Figure 1 , 2 As shown, it includes:

[0048] Base plate 1;

[0049] Panel 2 is fixed to the base plate 1. The base plate 1 and panel 2 can be formed by sheet metal stamping. The connection between the base plate 1 and panel 2 can be achieved by riveting, screwing or sheet metal integral forming.

[0050] Connectors 3 are disposed on both sides of the panel 2. Generally, when connecting the sub-board module and the main board module, force needs to be applied from both sides to ensure that the separation force between the sub-board module and the main board module is evenly distributed.

[0051] The connector 3 includes:

[0052] Sleeve 30 is fixed to the front surface 2A of panel 2;

[0053] A threaded connecting rod 31 is sleeved inside the sleeve 30. The head 31A of the threaded connecting rod 31 is located on the front surface 2A of the panel 2, and the tail 31B of the threaded connecting rod 31 extends out of the sleeve 30 and is confined to the rear surface 2B of the panel 2.

[0054] A knob 32 is fixed to the head 31A of the threaded connecting rod 31 and rotates integrally with the threaded connecting rod 31. The diameter of the knob 32 gradually decreases from the front end 32A to the rear end 32B, and the rear end 32B is fixed to the threaded connecting rod 31. The diameter of the front end 32A of the knob 32 is larger than the outer diameter of the sleeve. The knob 32 gradually decreases in diameter from the front end 32A to the rear end 32B to form a certain slope. This slope can be a flat surface or an inner arc surface, which can be set according to actual needs.

[0055] During the process of removing the daughterboard module from the motherboard module, the threaded connecting rod 31 engages with the threaded hole on the motherboard module for locking. The operator needs to rotate knob 32 to unlock the motherboard module and daughterboard module. At this time, the operator can use their fingers to grip between the sleeve 30 and knob 32. Because knob 32 has a reduced diameter near panel 2, the fingers can grip knob 32 more firmly to smoothly separate the daughterboard module and motherboard module by applying outward force.

[0056] In some scenarios, such as when the height of the sub-board module is small, the projection of the knob 32 on the panel 2 does not exceed the range of the panel 2, so as to avoid the knob 32 interfering with the adjacent sub-board modules.

[0057] In the embodiments described in this specification, the knob is provided with a structure that gradually decreases in diameter toward the panel, providing a larger operable area. The sloping knob can also provide a better grip for the operator. When the sub-board module is plugged into or removed from the main board module, force can be applied more effectively to the knob, which has locking and unlocking functions, thereby improving the maintenance efficiency of network devices with sub-board modules and main board modules.

[0058] Optionally, the knob 32, as Figure 2 As shown, it includes:

[0059] The operating part 320 is located at the front end 32A of the knob 32. The operating part 320 is used by the operator to hold and has a certain holding space. The operating part 320 has a larger size than other parts of the knob 32.

[0060] The transition portion 321 extends from the operating portion 320 toward the threaded connecting rod 31 and is fixed to the threaded connecting rod 31. The transition portion 321 has an inwardly concave arc surface, which is set to converge inward.

[0061] When the operator holds the knob 32, their fingertips can press against the inner arc surface of the transition part 321 to hold the operating part 320 more reliably, thereby improving the force applied when the operator pulls out the sub-board substrate.

[0062] Optionally, an anti-slip texture is formed on the outer periphery of the operating part 320, which allows the operator to have a better operating effect when rotating the knob 32 and prevents it from slipping off the knob 32.

[0063] Optional, such as Figure 3 As shown, a first limiting ring 300 is formed on the side edge of the sleeve 30 away from the panel 2. The first limiting ring 300 can be integrally formed with the sleeve 30, or it can be fixed to the sleeve 30 by welding, snap-fitting or other means.

[0064] The connector 3 further includes:

[0065] A return spring 33 is sleeved on the threaded connecting rod 31. One end of the return spring 33 abuts against the knob 32, and the other end of the return spring 33 abuts against the first limiting ring 300. That is, the return spring 33 is clamped between the first limiting ring 300 and the knob 32.

[0066] When connecting the sub-board module and the main board module via connector 3, when rotating knob 32, threaded connecting rod 31 is screwed into the corresponding structure on the main board module, and reset spring 33 is compressed between knob 32 and first limit ring 300.

[0067] When it is necessary to remove the sub-board module, rotate knob 32 to unlock it. Under the elastic force of reset spring 33, knob 32 is popped out, allowing the operator to better apply force to pull out the sub-board module.

[0068] Due to the presence of the return spring 33, when the knob 32 is unlocked, the return spring 33 applies a spring force that pushes the knob 32 out. If the spring force is too large, the threaded connecting rod 31 may fall out of the sleeve 30, resulting in the loss of the component. To avoid the above problem, furthermore, the connecting member 3, such as... Figure 4 As shown, it also includes:

[0069] The abutment block 34 is connected to the threaded connecting rod 31 and located outside the sleeve 30. One side of the abutment block 34 abuts against the first limiting ring 300.

[0070] like Figure 4 As shown in (A), when the return spring 33 is compressed, the abutment block 34 is spaced apart from the first limiting ring 300 by a certain distance, as... Figure 4As shown in (B), when the knob 32 is unlocked, the spring force of the reset spring 33 causes the knob 32 to move outward, and the abutment block 34 abuts against the first limit ring 300, which restricts the knob 32 from driving the threaded connecting rod 31 to move further, thus preventing the knob 32 and the threaded connecting rod 31 from falling off.

[0071] Optional, such as Figure 5 As shown, a second limiting ring 301 is formed in the middle of the sleeve 30;

[0072] The connector 3 further includes:

[0073] A return spring 33 is sleeved on the threaded connecting rod 31 and fixed between the second limiting ring 301 and the tail 31B of the threaded connecting rod 31.

[0074] When connecting the sub-board module and the main board module via connector 3, rotating knob 32 causes threaded connecting rod 31 to be screwed onto a corresponding structure on the main board module, and return spring 33 is stretched between threaded connecting rod 31 and the second limiting ring 301. Return spring 33 can be a tension spring, with one end fixed to the second limiting ring 301 and the other end fixed to threaded connecting rod 31 or a structure provided on threaded connecting rod 31.

[0075] When it is necessary to remove the sub-board module, rotate knob 32 to unlock it. Under the elastic force of reset spring 33, knob 32 is popped out, allowing the operator to better apply force to pull out the sub-board module.

[0076] Due to the presence of the return spring 33, when the knob 32 is unlocked, the return spring 33 applies a spring force that pushes the knob 32 out. If the spring force is too large, it may cause the threaded connecting rod 31 to separate from the return spring 33, and cause the threaded connecting rod 31 to fall out of the sleeve 30, resulting in the loss of the component. To avoid the above problems, the connector 3 further includes:

[0077] A connecting block 35 is disposed between the middle part 31C and the tail part 31B of the threaded connecting rod 31. One end of the return spring 33 is fixed to the second limiting ring 301, and the other end of the return spring 33 is fixed to the connecting block 35.

[0078] The connecting block 35 is disposed on the threaded connecting rod 31 to achieve a reliable connection with the return spring 33, thereby avoiding the problem of the threaded connecting rod 31 separating from the return spring 33 and coming out of the sleeve.

[0079] like Figure 5 As shown in (A), when the return spring 33 is stretched, the connecting block 35 and the second limiting ring 301 are spaced apart by a certain distance, as... Figure 5As shown in (B), when the knob 32 is unlocked, the elastic force of the return spring 33 causes the knob 32 to move outward. The connecting block 35 locks the return spring 33, restricting the further movement of the knob 32 and the threaded connecting rod 31, thus preventing the knob 32 and the threaded connecting rod 31 from falling off.

[0080] Of course, the above Figure 4 and Figure 5 This is for illustrative purposes only; the specific structure can be adjusted according to actual needs.

[0081] Optionally, the inner circumference of the second limiting ring 301 is formed with an internal thread that matches the threaded connecting rod 31.

[0082] The threaded connecting rod 31 has a partial external thread, and the second limiting ring 301 has an internal thread. During the locking process between the sub-board module and the main board module, the external thread screws through the second limiting ring 301 and disengages from the internal thread. When unlocking between the sub-board module and the main board module, under the action of the return spring 33, the portion of the threaded connecting rod 31 without external threads is pushed, and the portion of the threaded connecting rod 31 with external threads abuts against the internal thread of the second limiting ring 301, thereby limiting further movement of the threaded connecting rod 31 and preventing the threaded connecting rod 31 and the knob 32 from disengaging from the sleeve 30.

[0083] Correspondingly, this application also provides a daughterboard module 200, such as Figure 1 As shown, it includes:

[0084] The aforementioned sub-board substrate 100; and,

[0085] Circuit board 201 is fixed to the base plate 1 of the sub-board substrate 100.

[0086] Correspondingly, this application also provides a network device 400, such as Figure 6 As shown, it includes:

[0087] The motherboard module 401 has a sub-board slot in the middle, and a motherboard panel 402 is provided on both sides of the sub-board slot. Threaded holes are formed on the motherboard panel 402.

[0088] The aforementioned sub-board module 200 fixes the main board module 401 and the sub-board module 200 by means of a threaded connecting rod 31 on the sub-board module 200 engaging with a threaded hole.

[0089] The main board module 401 may be equipped with a captive screw 403, the diameter of which is smaller than the diameter of the knob 32 in the sub-board module 200.

[0090] Furthermore, the diameter of the knobs of the captive screw 403 and the knobs of the daughterboard module 200 needs to be smaller than the height of each functional module in the network device 400, so as to avoid interference problems during the removal of functional modules.

[0091] This functional module can be either a daughterboard module 200 or a motherboard module 401. The network device 400 can be a router, switch, server, firewall, or other similar device. It can be configured according to actual needs, and there are no restrictions on this.

[0092] The technical solutions provided in the embodiments of this specification may include the following beneficial effects:

[0093] In the embodiments described in this specification, the knob is provided with a structure that gradually decreases in diameter toward the panel. When the sub-board module is plugged into or unplugged from the main board module, force can be applied more effectively to the knob, which has locking and unlocking functions, thereby improving the maintenance efficiency of the device with sub-board and main board modules.
