Description

Technical Field

[0001] The present disclosure relates to a rack and an insert module of a server cabinet, and in particular to an elastic arm type foolproof structure of the rack and the insert module. Background Art

[0002] Today's power cabinets are often used for a variety of different load voltages, so the rack of the power cabinet can be used to insert various plug-in power modules suitable for different working voltages. In order to prevent the power module from docking with an inappropriate load, the cabinet and the power module are generally provided with mutually matching anti-fool structures. The anti-fool structure is generally in the form of a protruding stopper, and a corresponding notch is set on the counterpart to allow it to pass through. However, the anti-fool structure needs to be set at different positions for each specification, and the limited space on the opening edge of the slot can only set a small number of specification changes. Moreover, it is not easy to modify the anti-fool structure when the specification setting of the cabinet changes.

[0003] In view of this, the inventor has devoted himself to studying the above-mentioned prior art and has applied theoretical knowledge to try his best to solve the above-mentioned problems, which has become the goal of the inventor's improvement. Summary of the invention

[0004] The purpose of the present disclosure is to provide a spring-arm type fool-proof structure using a frame and an insertion module.

[0005] The present invention provides a foolproof structure of a frame and an insertion module, comprising a frame and an insertion module. The frame has a slot, the slot has an opening, a stopper and an actuating portion are arranged on the inner wall of the slot, and the actuating portion of the stopper is respectively connected to the opening. The insertion module has an elastic arm, which is arranged on one side of the insertion module, and the elastic arm has a retaining wall and an actuating slope protruding from the insertion module, wherein when the insertion end of the insertion module is inserted into the slot through the opening, an insertion direction into the slot is defined parallel to the longitudinal direction of the slot, the retaining wall is arranged vertically along the insertion direction, and the actuating slope is arranged obliquely along the insertion direction. A first stroke is defined from the actuating portion to the stopper along the insertion direction, and a second stroke is defined from the actuating slope to the retaining wall along the insertion direction. When the first stroke is greater than or equal to the second stroke, the actuating portion can push the actuating slope before the retaining wall reaches the stopper to cause the elastic arm to deflect. When the elastic arm deflects, the retaining wall retreats into the insertion module to dodge and pass through the stopper.

[0006] In one embodiment of the present disclosure, the insertion module has a body, one end of an elastic arm is fixed to the body and the elastic arm extends along the insertion direction, and the retaining wall and the actuating slope are jointly arranged at the other end of the elastic arm.

[0007] In one embodiment of the present disclosure, the insertion module has a body, one end of the elastic arm is fixed to the body and the elastic arm extends in the opposite direction of the insertion direction, and the retaining wall and the actuating slope are jointly arranged at the other end of the elastic arm.

[0008] In one embodiment of the present disclosure, the stopper is disposed at the opening.

[0009] In one embodiment of the present disclosure, a first channel is provided on the inner wall of the slot, and the first channel extends from the opening to the stopper in parallel with the insertion direction.

[0010] In one embodiment of the present disclosure, the actuating portion is disposed at the opening.

[0011] In one embodiment of the present disclosure, a second channel is provided on the inner wall of the slot, and the second channel extends from the opening to the actuating portion in parallel with the insertion direction.

[0012] In one embodiment of the present disclosure, a release portion is provided on the inner wall of the slot, and the elastic arm is provided with a release slope, and the release slope is inclined opposite to the insertion direction. When the insertion module exits the slot in the opposite direction of the insertion direction, the release portion can push against the release slope to cause the elastic arm to swing.

[0013] In one embodiment of the present disclosure, the elastic arm is provided with a first hook, and the retaining wall and the release slope are jointly configured on the first hook.

[0014] In one embodiment of the present disclosure, the elastic arm is provided with a second hook, and the actuating slope and the releasing slope are jointly configured on the second hook.

[0015] In one embodiment of the present disclosure, the foolproof structure further includes another insertion module with another second stroke defined, the other insertion module having another elastic arm, another retaining wall and another actuating slope, and another second stroke is defined from the another actuating slope to the other retaining wall along the insertion direction, the other second stroke is different from the second stroke and smaller than the first stroke, and the other insertion module can be inserted into the slot. When the other insertion module is inserted into the slot, the actuating portion can push against the other actuating slope before (or at the same time) the other retaining wall reaches the stopper, so that the other elastic arm deflects and the other retaining wall retreats into the other insertion module to avoid and pass through the stopper.

[0016] In summary, the foolproof structure of the frame and the insertion module disclosed in the present invention can make the configuration of the same set of stopper and actuating part partially compatible with multiple elastic arms of different specifications by adjusting the settings of the first stroke and the second stroke.

[0017] As long as the insertion modules meet the configuration that the first stroke is greater than or equal to the second stroke, they can be inserted into the corresponding slots. In other words, each slot can be configured with a different first stroke, and multiple insertion modules can also set a specific second stroke to be smaller than the first stroke of some slots, so that the insertion modules can exclude some slots to achieve the effect of backward compatibility by making the slots compatible with insertion modules of corresponding specifications and insertion modules below the corresponding specifications.

[0018] Therefore, it is sufficient to replace the appropriate elastic arm according to different power requirements. The fool-proof structure disclosed in the present invention can be easily adjusted to meet various different usage requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Figure 1It is a three-dimensional schematic diagram of the fool-proof structure of the rack and the insertion module of the first embodiment of the present disclosure. The first embodiment of the present disclosure provides a fool-proof structure for a rack 100 and an insertion module 200, which includes a rack 100 and at least one insertion module 200. In this embodiment, the insertion module 200 is a power module, but the present disclosure is not limited to this. The rack 100 has at least one slot 101 for plugging the insertion module 200. When the insertion module 200 is inserted into the slot 101, an insertion direction 103 is defined parallel to the longitudinal direction of the slot 101, and the insertion direction 103 is toward the inside of the slot 101. Taking the power module as an example, when the insertion module 200 is inserted into the slot 101 and positioned, it can dock with an electric power connector (not shown in the figure) located at the bottom 1012 of the slot 101.

[0064] In this embodiment, a slot 101 of a rack 100 and an insert module 200 are used as an example for explanation. One end of the slot 101 has an opening 1011, and the other end of the slot 101 has a bottom 1012 opposite to the opening 1011. A stopper 110 and an actuating portion 120 are provided on the inner wall of the slot 101, and the stopper 110 and the actuating portion 120 are respectively connected to the opening 1011. Here, the aforementioned "connected to the opening 1011" means that there is no obstruction from the stopper 110 or the actuating portion 120 to the opening 1011 along the insertion direction 103. In this embodiment, a first channel 1021 is provided on the inner wall of the slot 101, and the first channel 1021 extends from the opening 1011 to the stopper 110 in parallel with the insertion direction 103; the actuating portion 120 is disposed at the opening 1011.

[0065] Figure 2 FIG. 1 is a perspective schematic diagram of an insertion module in the first embodiment of the present disclosure. Figure 2 The insert module 200 has a body 210 and an elastic arm 220. The body 210 is in the shape of an elongated strip. An insertion end 211 is defined on the body 210 of the insert module 200 along its longitudinal direction. When the insert module 200 is inserted into the slot 101, the insert module 200 first passes through the opening 1011 of the slot 101 with its insertion end 211 and is inserted into the slot 101. The elastic arm 220 is disposed on one side of the body 210 of the insert module 200. The elastic arm 220 is provided with a first hook 221 and a second hook 222. The first hook 221 is provided with a retaining wall 310, and the second hook 222 is provided with an actuating slope 320. One end of the elastic arm 220 shown in this embodiment is fixed to the body 210. The elastic arm 220 extends along the longitudinal direction of the body 210 and extends in the insertion direction 103. The first hook 221 and the second hook 222 are jointly provided at the other end of the elastic arm 220.

[0066] In this embodiment, the elastic arm 220 is disposed adjacent to the insertion end 211 of the body 210 of the insertion module 200 , but the disclosure is not limited thereto. For example, the elastic arm 220 may also be disposed at the front end 212 of the body 210 of the insertion module 200 opposite to the insertion end 211 .

[0067] Figure 3 It is a three-dimensional schematic diagram of the insertion module plug-in slot in the first embodiment of the present disclosure. Figure 4 This is an enlarged three-dimensional schematic diagram of the foolproof structure of the rack and the insertion module of the first embodiment of the present disclosure. Figure 3 and Figure 4 , the first hook 221 and the second hook 222 both protrude from the body 210 of the insertion module 200 and can interfere with the structure of the frame 100. Specifically, the retaining wall 310 is arranged perpendicular to the insertion direction 103 of the slot 101 and the retaining wall 310 is arranged along (here refers to the normal direction of the retaining wall 310) the insertion direction 103 of the slot 101, and the actuating slope 320 is arranged obliquely along (here refers to the normal direction of the actuating slope 320) the insertion direction 103. The structural interference fit of the first hook 221 and the second hook 222 and the frame 100 is described as follows.

[0068] Figure 5 1 is a front view of the foolproof structure of the frame and the insertion module in the first embodiment of the present disclosure. Figure 5 In this embodiment, a first stroke 410 is defined from the actuating portion 120 to the stop portion 110 along the insertion direction 103, and a second stroke 420 is defined from the actuating slope 320 (herein, referring to the highest point of the actuating slope 320, that is, the rearmost edge of the actuating slope 320 along the insertion direction 103) to the retaining wall 310 along the insertion direction 103. The first stroke 410 and the second stroke 420 are positive values ​​in the forward direction of the insertion direction 103, and the first stroke 410 and the second stroke 420 are negative values ​​in the reverse direction of the insertion direction 103.

[0069] Figure 6 It is an enlarged three-dimensional schematic diagram of the use status of the fool-proof structure of the frame and the insertion module of the first embodiment of the present disclosure. Figure 7 It is a front view of the use status of the fool-proof structure of the rack and the insertion module in the first embodiment of the present disclosure. Figure 8 Schematic diagram of the first embodiment of the present invention, showing the frame and the insert module foolproof structure and the spring arm in action. Figures 5 to 8When the insertion end 211 of the insertion module 200 is inserted into the slot 101 through the opening 1011, if the first stroke 410 is configured to be greater than or equal to the second stroke 420, the actuating portion 120 can push the actuating slope 320 before (or at the same time as) the retaining wall 310 reaches the stopper 110 to deflect the elastic arm 220. Further, when the elastic arm 220 deflects under the aforementioned condition, the first hook 221 and the second hook 222 both retract into the body 210 of the insertion module 200, that is, the retaining wall 310 retracts into the body 210 of the insertion module 200 and avoids and passes through the stopper 110, so the insertion module 200 can be further pushed into the slot 101. Specifically, the stopper 110 can be any local structure on the frame 100 configured corresponding to the retaining wall 310 and used to abut against the retaining wall 310 , and the actuating portion 120 can be any local structure on the frame 100 configured corresponding to the actuating slope 320 and used to abut against the actuating slope 320 .

[0070] The foolproof structure is not limited to preventing the insertion module 200 from being inserted into an inappropriate slot 101 , as long as it can prevent the insertion module 200 from docking with the power connector at the bottom 1012 of the inappropriate slot 101 .

[0071] Fig. 9 FIG. 1 is a perspective diagram of the insertion module of the first embodiment of the present disclosure being inserted into the slot. Fig. 9 When the insertion module 200 is inserted into the slot 101 and positioned so that the first hook 221 and the second hook 222 are buckled into the corresponding buckle holes 1041 , 1042 of the bottom 1012 of the slot 101 , the insertion module 200 is positioned in the slot 101 .

[0072] At least one release portion 130 is provided on the inner wall of the slot 101, and at least one release slope 330 is provided on the elastic arm 220, and the release slope 330 is arranged obliquely opposite to the insertion direction 103. The release portion 130 can be any local structure on the frame 100 that is arranged corresponding to the release slope 330 and is used to abut against the release slope 330. When the insertion module 200 exits the slot 101 in the opposite direction of the insertion direction 103, the release portion 130 can push against the release slope 330 to make the elastic arm 220 swing. In this embodiment, the elastic arm 220 is provided with two release portions 130 and two release slopes 330, and the retaining wall 310 and one of the release slopes 330 are jointly arranged on the first hook 221, and the actuating slope 320 and the other release slope 330 are jointly arranged on the second hook 222. The release portions 130 corresponding to the release slopes 330 are formed on the inner edges of each buckle hole 1041, 1042.

[0073] Furthermore, a locking spring arm hook 230 can also be set at the front end 212 of the main body 210 of the insertion module 200. When the insertion module 200 is inserted into the slot 101 and positioned, it can be fixed by snapping the locking spring arm hook 230 onto the inner wall of the slot 101. One end of the locking spring arm hook 230 is fixed to the main body 210 of the insertion module 200 and the other end of the locking spring arm hook 230 protrudes from the front end 212 of the main body 210 of the insertion module 200 for the user to operate and unlock the locking spring arm hook 230.

[0074] Fig.10 It is a three-dimensional schematic diagram of the insertion module in the second embodiment of the present disclosure. Fig.11 It is a front view of the fool-proof structure of the rack and the insertion module in the second embodiment of the present disclosure. Fig.12 It is a front view of the use status of the fool-proof structure of the rack and the insertion module of the second embodiment of the present disclosure.

[0075] See also Figures 10 to 12 The foolproof structure of the rack and the insertion module of the second embodiment of the present disclosure is shown. In this implementation, another slot 101a of the rack 100 and another insertion module 200a opposite thereto are used as examples for explanation as follows. One end of the slot 101a has an opening 1011a. A stopper 110a and an actuating portion 120a are provided on the inner wall of the slot 101a, and the stopper 110 and the actuating portion 120 are respectively connected to the opening 1011a. Here, the aforementioned "connected to the opening 1011a" means that there is no obstruction along the insertion direction 103 from the stopper 110a or the actuating portion 120a to the opening 1011a. In this embodiment, a first channel 1021a is provided on the inner wall of the slot 101a, and the first channel 1021a extends from the opening 1011a to the stopper 110a in parallel with the insertion direction 103; the actuating portion 120a is disposed at the opening 1011a. In this embodiment, the configuration position of the stopper 110 a is different from that in the first embodiment.

[0076] The insert module 200a has a body 210a and an elastic arm 220a. The body 210a is in the shape of an elongated strip. An insertion end 211a is defined on the body 210a of the insert module 200a along its longitudinal direction. When the insert module 200a is inserted into the slot 101a, the insert module 200a first passes through the opening 1011 of the slot 101 with its insertion end 211a and is inserted into the slot 101a. The elastic arm 220a is disposed on one side of the body 210a of the insert module 200a. The elastic arm 220a is provided with a first hook 221a and a second hook 222a. The first hook 221a is provided with a retaining wall 310a, and the second hook 222a is provided with an actuating slope 320a. One end of the elastic arm 220a shown in this embodiment is fixed to the body 210a. The elastic arm 220a extends along the longitudinal direction of the body 210a and extends along the insertion direction 103. The first hook 221a and the second hook 222a are disposed together at the other end of the elastic arm 220a.

[0077] The elastic arm 220a shown in this embodiment has one end fixed to the body 210a, and the elastic arm 220a extends along the insertion direction 103 and the elastic arm 220a extends in the insertion direction 103. The first hook 221a and the second hook 222a are jointly arranged at the other end of the elastic arm 220a, and both the first hook 221a and the second hook 222a protrude from the body 210a of the insertion module 200a and can interfere with the structure of the rack 100. Specifically, the retaining wall 310a is arranged perpendicular to the insertion direction 103 of the slot 101a and the retaining wall 310a is in the direction (here, the normal direction of the retaining wall 310a) of the insertion direction 103 of the slot 101a, and the actuating slope 320a is arranged obliquely in the direction (here, the normal direction of the actuating slope 320a) of the insertion direction 103. In this embodiment, the configuration position of the actuating slope 320a is different from that of the first embodiment. The structural interference fit between the first hook 221 a and the second hook 222 a and the frame 100 is described below.

[0078] In this embodiment, a first stroke 410a is defined from the actuating portion 120a to the stop portion 110a along the insertion direction 103, and a second stroke 420a is defined from the actuating slope 320a (here referring to the front end 212 of the actuating slope 320a along the insertion direction 103) to the retaining wall 310a along the insertion direction 103. The first stroke 410a and the second stroke 420a are positive values ​​in the forward direction of the insertion direction 103, and the first stroke 410a and the second stroke 420a are negative values ​​in the reverse direction of the insertion direction 103.

[0079] Fig.13 This is a front view of the use state of the foolproof structure of the frame and the insertion module of the third embodiment of the present disclosure. Fig.13In the third embodiment of the present disclosure, the insertion module 200a shown in the second embodiment is inserted into the slot 101 shown in the first embodiment. The first stroke 410a of this embodiment is smaller than the first stroke 410 of the first embodiment, and the second stroke 420a of this embodiment is greater than or equal to the second stroke 420 of the first embodiment, but the first stroke 410a of this embodiment is smaller than the second stroke 420a. Therefore, the retaining wall 310 pushes against the stopper 110 before (or at the same time as) the actuating slope 320 reaches the actuating portion 120 to prevent the insertion module 200 from further advancing into the slot 101, so that the insertion module 200a in this example cannot be inserted into the slot 101 of incompatible specifications.

[0080] Fig.14 This is a front view of the use state of the foolproof structure of the frame and the insertion module of the fourth embodiment of the present disclosure. Fig.14 In the fourth embodiment of the present disclosure, the insertion module 200 shown in the first embodiment is inserted into the slot 101a shown in the second embodiment. The first stroke 410a of this embodiment is greater than or equal to the first stroke 410 of the first embodiment, and the second stroke 420 of this embodiment is less than the second stroke 420a of the second embodiment, but the first stroke 410a of this embodiment is still greater than or equal to the second stroke 420. During the insertion process, the actuating portion 120a can push against the actuating slope 320 before the retaining wall 310 reaches the stop portion 110a (or at the same time) to deflect the elastic arm 220. Therefore, referring to Fig.11 and Fig.14 As shown, the slot 101a shown in the second embodiment and the fourth embodiment can be compatible with various specifications of the insertion modules 200, 200a. Therefore, in addition to being able to insert the corresponding insertion module 200a, the insertion module 200 that meets the configuration of the first stroke 410a being greater than or equal to the second stroke 420 can be compatible with the slot 101a of this embodiment. In other words, Figure 5 and Fig.11 The power connectors in the multiple slots 101 are supplied with different load voltages, and each slot 101, 101a can be configured with a different first stroke 410, 410a. Specifically, the larger the load voltage, the larger the first stroke 410a. The multiple insertion modules 200, 200a are also suitable for different working voltages. However, if Fig.11 and Fig.13 As shown, one of the insertion modules 200a can set a specific second stroke 420a to be smaller than the first stroke 410a of some slots 101a, thereby excluding some slots 101 whose load voltage exceeds its working voltage.

[0081] That is to say, in this embodiment, the foolproof structure may include: Figure 5 An insertion module 200 shown and Fig.11 Another insertion module 200a is shown. Fig.12 and Fig.14 As shown, two insertion modules 200, 200a are commonly used in the same slot 101a.

[0082] One of the insertion modules 200 has an elastic arm 220, a retaining wall 310 and an actuating slope 320, and a second stroke 420 is defined along the insertion direction from the actuating slope 320 to the retaining wall 310, and the second stroke 420 is smaller than the first stroke 410a, and the insertion module 200 can be inserted into the slot 101a. When the insertion module 200 is inserted into the slot 101a, the actuating portion 120a can push against the actuating slope 320 before the retaining wall 310 reaches the stopper 110a (or at the same time), so that the elastic arm 220 deflects and the retaining wall 310 retreats into the insertion module 200 to avoid and pass through the stopper 110a.

[0083] Another insertion module 200a is defined with another second stroke 420a. Specifically, another insertion module 200a has another elastic arm 220a, another retaining wall 310a and another actuating slope 320a. Another second stroke 420a is defined along the insertion direction from another actuating slope 320a to another retaining wall 310a. Another second stroke 420a is different from the second stroke and smaller than the first stroke 410a. Another insertion module 200a can be inserted into the slot 101a. When another insertion module 200a is inserted into the slot 101a, the actuating portion 120 can push against another actuating slope 320a before another retaining wall 310a reaches the stopper 110a (or at the same time), so that another elastic arm 220a is deflected and another retaining wall 310a is retracted into another insertion module 200a to avoid and pass through the stopper 110a.

[0084] Through the above configuration, a slot 101 with a lower load voltage and another slot 101a with a higher load voltage can be configured. Moreover, the insertion module 200 with a lower working voltage corresponds to the slot 101 with a lower load voltage, and the other insertion module 200a with a higher working voltage corresponds to the slot 101a with a higher load voltage. The slot 101a with a higher load voltage is compatible with the insertion module 200a of the corresponding specification and is downwardly compatible with other insertion modules 200 of lower specifications. The insertion module 200a of a higher specification cannot be inserted into the slot 101 with a specification higher than the corresponding specification. Therefore, power overload of the device can be avoided. However, the present disclosure is not limited to the above specifications, and can also be applied to other specifications, such as signal transmission degree, etc.

[0085] In summary, the foolproof structure of the frame and the insertion module disclosed in the present invention can make the configuration of the same set of stopper 110a and actuating portion 120a partially compatible with multiple insertion modules 200, 200a of different specifications by adjusting the settings of the first stroke 410a and the second stroke 420, 420a.

[0086] Fig.15 This is a front view of the use state of the foolproof structure of the rack and the insertion module of the fifth embodiment of the present disclosure. Fig.15 The foolproof structure of the rack and the insertion module of the fifth embodiment of the present disclosure is shown. In this implementation, another slot 101b of the rack 100 and another insertion module 200b opposite thereto are used as an example for explanation as follows.

[0087] In this embodiment, one end of the slot 101b has an opening 1011b, and the slot 101b has a stopper 110b and an actuating portion 120b disposed on the inner wall of the slot 101b, and the stopper 110b and the actuating portion 120b are respectively connected to the opening 1011. Here, the aforementioned “connected to the opening 1011b” means that there is no obstruction along the insertion direction 103 from the stopper 110b or the actuating portion 120b to the opening 1011b.

[0088] In this embodiment, the stopper 110b is disposed at the opening 1011b. A second channel 1022b is disposed on the inner wall of the insertion slot 101b. The second channel 1022b extends from the opening 1011b to the actuating portion 120b in parallel with the insertion direction 103.

[0089] The insert module 200b has a body 210b and an elastic arm 220b. The body 210b is in the shape of a long strip. An insertion end 211b is defined along the longitudinal direction of the body 210b of the insert module 200b. When the insert module 200b is inserted into the slot 101b, the insert module 200b first passes through the opening 1011b of the slot 101b with its insertion end 211b and is inserted into the slot 101b. The elastic arm 220b is disposed on one side of the body 210b of the insert module 200b. The elastic arm 220b is provided with a first hook 221b and a second hook 222b. The first hook 221b is provided with a retaining wall 310b, and the second hook 222b is provided with an actuating slope 320b. One end of the elastic arm 220b shown in this embodiment is fixed to the body 210b, and the elastic arm 220b extends along the longitudinal direction of the body 210b and extends along the insertion direction 103. The first hook 221 and the second hook 222b are jointly disposed at the other end of the elastic arm 220b.

[0090] The first hook 221b and the second hook 222b are both protruding from the body 210b of the insertion module 200b and can be interfered with by the structure of the rack 100. Specifically, the retaining wall 310b is arranged perpendicular to the insertion direction 103 of the slot 101b and the retaining wall 310b is arranged along (here refers to the normal direction of the retaining wall 310b) the insertion direction 103 of the slot 101b, and the actuating slope 320b is arranged obliquely along (here refers to the normal direction of the actuating slope 320b) the insertion direction 103. The structural interference fit of the first hook 221b and the second hook 222b and the rack 100 is described as follows.

[0091] In this embodiment, a first stroke 410b is defined from the actuating portion 120b to the stop portion 110b along the insertion direction 103, and a second stroke 420b is defined from the actuating slope 320b (here referring to the highest point of the actuating slope 320b, i.e., the rearmost edge of the actuating slope 320b along the insertion direction 103) to the retaining wall 310b along the insertion direction 103. The first stroke 410b and the second stroke 420b are positive values ​​in the forward direction of the insertion direction 103, and the first stroke 410b and the second stroke 420b are negative values ​​in the reverse direction of the insertion direction 103.

[0092] When the insertion end 211b of the insertion module 200b is inserted into the slot 101b through the opening 1011b, if the first stroke 410b is configured to be greater than or equal to the second stroke 420b, the actuating portion 120b can push the actuating slope 320b before the retaining wall 310b reaches the stopper 110b (or at the same time) to cause the elastic arm 220b to deflect. Further, when the elastic arm 220b deflects under the aforementioned condition, the first hook 221b and the second hook 222b both retract into the body 210b of the insertion module 200b, that is, the retaining wall 310b retracts into the body 210b of the insertion module 200b and evades and passes through the stopper 110b, so the insertion module 200b can be further pushed into the slot 101b. Specifically, the stopper 110b can be any local structure on the frame 100 configured corresponding to the retaining wall 310b and used to abut against the retaining wall 310, and the actuating portion 120b can be any local structure on the frame 100 configured corresponding to the actuating slope 320b and used to abut against the actuating slope 320b.

[0093] In this embodiment, when the insertion module 200b is inserted into its corresponding slot 101b along the insertion direction 103, although the insertion module 200b as a whole first passes through the stopper 110b, the first stroke 410b and the second stroke 420b of this embodiment are both opposite to the insertion direction 103 and are both negative values, and the first stroke 410b is still greater than or equal to the second stroke 420b. During the insertion process, the actuating portion 120b can push against the actuating slope 320b before the retaining wall 310b reaches the stopper 110b (or at the same time) to cause the elastic arm 220b to deflect.

[0094] Fig.16 FIG. 1 is a partial three-dimensional schematic diagram of an insertion module in a sixth embodiment of the present disclosure. Fig.16 The sixth embodiment of the present disclosure provides another insertion module 200c different from the above-mentioned embodiments, which has a body 210c. The structure of the insertion module 200c of this embodiment is roughly the same as that of the first embodiment. The difference between this embodiment and the above-mentioned examples is that one end of the elastic arm 220c is fixed to the body 210, the elastic arm 220c extends along the longitudinal direction of the insertion module 200c and the elastic arm 220c extends in the opposite direction of the insertion direction 103, and the retaining wall 310c and the actuating slope 320 are arranged at the other end of the elastic arm 220c. In this embodiment, the relative position configuration of the first hook 221c and the second hook 222c is the same as the first hook 221 and the second hook 222 of the first embodiment. Therefore, the insertion module 200c of this embodiment can be compatible with the slot 101 of the first embodiment. This configuration allows the first hook 221c and the second hook 222c to have a larger distance from the end surface of the insertion end 211c. Therefore, when inserting the insertion module 200c, there is no need to align the first hook 221c and the second hook 222c first, so it is easier to insert the insertion module 200c into the opening 1011 of the slot 101.

[0095] In summary, as long as the appropriate elastic arm is replaced according to different specifications, the slot that allows the insertion module to be inserted can be set. The foolproof structure disclosed in the present invention is easy to adjust to various different usage requirements. In addition, there is a large space in the longitudinal direction of the slot and the insertion module relative to the opening edge to allow the first stroke and the second stroke to be set respectively according to more different specifications.

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Other equivalent changes that apply the patent spirit of the present invention should all fall within the patent scope of the present invention.
