Description

Technical Field

[0001] This utility model relates to the field of board insertion technology, and in particular to a board device with an integrated pull-out aid and a bit error rate tester. Background Technology

[0002] Quick-release boards or modules on a chassis typically use board-to-board connectors for power supply and communication with the chassis. When there are many connectors or pins, the clamping force is significant. Furthermore, for aesthetic reasons and other requirements (such as electromagnetic compatibility testing, EMC), the board or module's front panel is flush with the chassis panel. When replacing a board or module, there is no point of force application, necessitating the design of an additional extraction mechanism. Currently, most mainstream board or module fastening and ejection mechanisms use screws and extraction aids, or screws with handles.

[0003] The screw and handle method is the simplest in design, but installation and disassembly require corresponding tools, making it relatively cumbersome. Using quick-release screws to install boards or modules requires removing or tightening the screws to secure them to the chassis; however, it's difficult to remove the boards or modules from the chassis using only quick-release screws. Using a pull-out tool can solve the problem of removing boards or modules from the chassis relatively well, but securing them usually requires additional measures, such as adding screws. Therefore, there is an urgent need to design a structure that can both remove boards from the chassis and secure them to the chassis. Utility Model Content

[0004] One objective of this invention is to provide a board device for an integrated pull-out aid, thereby solving the technical problem in the prior art where additional connectors are required to fix the board to the chassis when using the pull-out aid.

[0005] A further objective of this invention is to improve the ease of unlocking and locking the puller.

[0011] During the process of inserting the board device into the chassis and connecting the first board and the second board, the locking part abuts against the second limiting part and rotates under force until it is locked with the second limiting part; the locking pin is controlled to lock with the first limiting part, so that the board device and the chassis are in a locked state.

[0012] Optionally, the locking element includes:

[0013] The locking pin is slidably mounted on the body along a first horizontal direction;

[0014] An elastic element is arranged along the first horizontal direction, with one end abutting against the body and the other end abutting against the locking pin.

[0015] An operating element, connected to the locking pin, is used to controllably drive the locking pin to slide back and forth along the first horizontal direction, so that the locking pin is locked or separated from the first limiting part.

[0016] Optionally, the housing includes:

[0017] A base plate, wherein the claw is rotatably connected to the base plate, and the first plate is mounted on the base plate;

The second horizontal direction is perpendicular to the first horizontal direction.

[0021] The locking pin includes a first part and a second part connected to each other. The first part is located in the first guide groove, and the second part is located in the second guide groove. The locking pin is configured such that when it moves to abut against the first side, the first part retracts into the first guide groove, thereby separating from the first limiting part; when it moves to abut against the second side, the first part extends out of the first guide groove, thereby locking with the first limiting part.

[0022] Optionally, the body has a first mounting groove, the locking pin has a second mounting groove, one end of the elastic member is located in the first mounting groove, and the other end is mounted in the second mounting groove.

Both the first board and the pull-out aid are mounted on the housing. The pull-out aid includes at least one locking mechanism. During the insertion of the board into the main body, the locking mechanism's engaging part abuts against the second limiting part and rotates under force until it is locked in place. The locking pin of the locking mechanism is then controlled to lock against the first limiting part on the housing, thus locking the board to the chassis. In this technical solution, the locking mechanism of the pull-out aid not only facilitates the insertion of the first board into the chassis for connection with the second board, but also, through the cooperation of the engaging part with the second limiting part and the locking pin with the first limiting part, secures the board within the chassis without the need for additional bolts.

Figure 2 This is a schematic diagram of the board device 100 according to an embodiment of the present invention just pushed into the chassis. Figure 3 This is a schematic structural diagram of the board device 100 and the chassis in an unlocked state according to an embodiment of the present invention. Figure 4 This is a schematic cross-sectional view of the board device 100 and the chassis in a locked state according to an embodiment of the present invention. Figure 5 This is a schematic exploded view of a locking mechanism 20 according to an embodiment of the present invention, wherein, Figure 2 The arrow in the diagram indicates the direction in which the board device 100 is pushed into the chassis. For example... Figures 1 to 5As shown, in a specific embodiment, the integrated pull-out device 100 includes a housing 10, a first card 30, and a pull-out aid. The housing 10 has at least one first limiting portion 111. The first card 30 is mounted on the housing 10 and can be inserted into or separated from a second card (not shown) inside a chassis. The chassis includes at least one guide plate 200, on which a second limiting portion 210 is provided. The pull-out aid includes at least one locking mechanism 20, each locking mechanism 20 including a claw 21 and a locking member 22. The claw 21 is rotatably mounted on the housing 10 and has a locking portion 211 that can extend out of the housing 10. The locking member 22 is rotatably connected to the claw 21 and has a locking pin 223. During the process of inserting the card device 100 into the chassis, causing the first card 30 to be inserted into the second card, the locking portion 211 abuts against the second limiting portion 210 and is rotated under force until it is locked with the second limiting portion 210. Locking pin 223 is controlled to engage with first limiting part 111, so that board device 100 and chassis are locked. Here, housing 10 is provided with an opening for the latching part 211 to extend out. Since the latching part 211 extends out of housing 10, during the process of inserting into chassis, the latching part 211 will first contact the second limiting part 210. During the continued pushing process, the latching part 211 will be rotated under force until it is locked with the second limiting part 210.

[0050] In this embodiment, the locking mechanism 20 of the pull-out aid not only helps the first board 30 to be inserted into the chassis for insertion with the second board, but also, through the cooperation of the snap-fit ​​part 211 and the second limiting part 210 and the cooperation of the locking pin 223 and the first limiting part 111, can fix the board device 100 in the chassis without the need for additional bolts. It can simultaneously achieve the effects of assisting insertion and removal and fixing, thus improving the convenience of installation.

[0051] In some embodiments, the locking member 22 includes a body 221, an elastic member 224, and an operating member 222. A locking pin 223 is slidably mounted on the body 221 along a first horizontal direction. The elastic member 224 is arranged along the first horizontal direction, with one end abutting against the body 221 and the other end abutting against the locking pin 223. The operating member 222 is connected to the locking pin 223 and is used to controllably drive the locking pin 223 to reciprocate along the first horizontal direction, thereby locking or disengaging the locking pin 223 from the first limiting portion 111. Here, the first horizontal direction is the... Figure 2 In the left and right direction. After the locking part 211 and the second limiting part 210 are locked together, the operator manually operates the operating part 222, first driving the locking pin 223 to retract into the body 221. At this time, the elastic element 224 is in a compressed state. Then, the body 221 is rotated. When the body 221 is aligned with the first limiting part 111, the operating part 222 is released. The locking pin 223 extends out of the body 221 under the force of the elastic element 224, thereby locking with the first limiting part 111.

[0052] In this embodiment, the locking and unlocking of the locking member 22 can be achieved by operating the operating member 222, which is convenient to operate and has a simple structure.

[0053] In some embodiments, the housing 10 includes a base plate 12 and an end plate 11. A pawl 21 is rotatably connected to the base plate 12, and a first plate clip 30 is mounted on the base plate 12. The end plate 11 is provided with a first limiting portion 111, and an operating member 222 is located on the outer side of the end plate 11. Here, the base plate 12 is located at the bottom of the housing 10, and the pawl 21 is rotatably connected to the base plate 12 via a rotating shaft 23. The end plate 11 is located on the front side of the housing 10, and the base plate 12 and the end plate 11 are arranged vertically.

[0054] In some embodiments, when the locking pin 223 is engaged with the first limiting part 111, the end face of the body 221 is flush with the end face of the housing 10, and only the operating member 222 protrudes from the end plate 11, which can achieve the effect of convenient operation while ensuring aesthetics.

[0055] In some embodiments, the body 221 has a groove extending along a first horizontal direction, and a locking pin 223 is mounted on the groove and is slidable along the groove. An operating member 222 is mounted at a position opposite to the groove and is located outside the locking member 22.

[0056] Figure 6 This is a schematic structural diagram of the locking pin 223 and the operating member 222 according to an embodiment of the present invention. Figure 7 This is a schematic structural diagram of the first guide groove 26 and the second guide groove 27 according to an embodiment of the present invention. Figures 6 to 7 As shown, and see Figures 1 to 5 In some embodiments, the slide portion has a first guide groove 26 and a second guide groove 27 arranged overlappingly along a second horizontal direction. The second guide groove 27 has a first side and a second side opposite to each other, with the second side closer to the end of the locking pin 223. The second horizontal direction is perpendicular to the first horizontal direction. The locking pin 223 includes a first portion 24 and a second portion 25 connected to each other. The first portion 24 is located in the first guide groove 26, and the second portion 25 is located in the second guide groove 27. The locking pin 223 is configured such that when it moves to abut against the first side, the first portion 24 retracts into the first guide groove 26, thereby separating from the first limiting portion 111; when it moves to abut against the second side, the first portion 24 extends out of the first guide groove 26, thereby locking with the first limiting portion 111. Here, the second horizontal direction is the attached... Figure 2 The up and down directions in the middle.

[0057] In some embodiments, the locking pin 223 is connected to the operating member 222 by a screw. In another embodiment, the locking pin 223 may also be connected to the operating member 222 by other means.

[0058] See Figure 4In some embodiments, the body 221 has a first mounting groove 226, the locking pin 223 has a second mounting groove 225, and one end of the elastic member 224 is located in the first mounting groove 226, while the other end is mounted in the second mounting groove 225. This embodiment, through the design of the first mounting groove 226 and the second mounting groove 225, can limit the two ends of the elastic member 224, preventing displacement. Here, the elastic member 224 is a spring. In other embodiments, the elastic member 224 can also be other components with the same properties as a spring.

[0059] In some embodiments, the locking member 22 further includes a limiting post, with its two ends located in the first mounting groove 226 and the second mounting groove 225 respectively, and the elastic member 224 sleeved on the limiting post.

[0060] In some embodiments, the second limiting portion 210 is a protrusion. The engaging portion 211 has two hooks 212 and a groove 213 located between the two hooks 212. During the insertion of the board device 100 into the chassis, one of the hooks 212 protrudes from the housing 10 and abuts against one side of the second limiting portion 210, and rotates around the second limiting portion 210 until the other hook 212 engages with the other side of the second limiting portion 210, and the second limiting portion 210 is inserted into the groove 213. The process of inserting the board device 100 into the chassis can be referred to in sequence. Figure 2 , Figure 3 and Figure 4 .

[0061] In some embodiments, the locking mechanism 20 further includes a torsion spring 28, which is installed between the claw 21 and the locking member 22. When the locking pin 223 is unlocked from the first limiting part 111, the locking member 22 is ejected from the housing 10 under the force of the torsion spring 28. At this time, the claw 21 and the second limiting part 210 are still locked. Only when the operator pulls the board device 100 out of the chassis will the claw 21 disengage from the second limiting part 210.

[0062] In some embodiments, there are two locking mechanisms 20, which are respectively disposed on opposite sides of the first board 30. The operator can simultaneously operate the operating parts 222 of the two locking mechanisms 20 to achieve simultaneous unlocking and locking. Here, the chassis is provided with two guide plates 200 arranged opposite each other, each guide plate 200 having a second limiting part 210, and each second limiting part 210 corresponding to one locking mechanism 20.

[0063] This embodiment is provided with two locking mechanisms 20, which can fix the left and right sides of the first board 30, thereby improving the stability of the first board 30 and the chassis installation.

[0064] In some embodiments, the present invention also provides a bit error rate tester, which includes a chassis and a board device 100 for an integrated pull-out aid in any of the above embodiments. The chassis has a second board and at least one guide plate 200, and the guide plate 200 is provided with a second limiting part 210. The board device 100 will not be described in detail here.
