Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a slot-type PCB circuit board. Background Art

[0002] Socket-type PCBs typically feature slots designed into the board for mounting external components or expansion cards. This design primarily provides greater flexibility and scalability, enabling the board to support different types of hardware or modules, such as memory modules, expansion cards, and storage devices. Socket-type PCBs are widely used in computers, servers, communications equipment, consumer electronics, and other fields.

[0003] Currently, existing slot-type PCB circuit boards use movable latches installed at both ends of the slot. The latch design is particularly important in slot-type PCB circuit boards. However, the current white latches will cause material fatigue under long-term stress, reduce tightness, reduce the latch function, or even break, making it impossible to clamp and fix external components. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a slot-type PCB circuit board, which has the advantages of being able to ensure the tightness of plugged-in external components during long-term use. It solves the problem that the stress on the lever on the slot deteriorates and the tightness decreases after long-term use, making it impossible to fully fix the plugged-in external components.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a slot-type PCB circuit board, comprising a circuit board and a slot assembly, wherein multiple groups of slot assemblies are fixed on the circuit board, and external components are connected to the slot assemblies by plugging to realize data transmission and power supply, thereby improving the scalability of the system.

[0006] The slot assembly consists of a plug-in box and a retaining member. The plug-in box is fixed on the circuit board. A plug-in slot is provided on the plug-in box. An external component is plugged into the plug-in slot. Push rods are movably sleeved on both ends of the plug-in box. At the same time, connecting slots are provided at both ends of the plug-in box. The connecting slots are connected to the plug-in slots. The push rods pass through the connecting slots. External components of the same model and size are plugged into the plug-in slots to connect the external components to the circuit board.

[0007] The retaining member includes a connecting block that is movably sleeved in the connecting groove, a sleeve groove is opened on the connecting block, a sleeve block is movably sleeved in the sleeve groove, and a retaining protrusion is provided on the sleeve block. The retaining protrusion is used to fix the external component. When the connecting block is completely in the connecting groove, the retaining protrusion is clamped on the side of the corresponding end of the external component to fix the plugged external component. When the connecting block slides outward, it is separated from the side of the external component, so that the plugged external component can be taken out.

[0008] When the slot-type PCB circuit board is connected to the external component, the external component is plugged into the corresponding plug-in box. At this time, the side of the external component is clamped in the retaining bayonet. By pressing the push rods at both ends of the plug-in box, the push rod is moved downward, pushing the set block to move downward from the set slot, so that the retaining protrusion drives the clamped external component to be fully inserted downward into the deep part of the plug-in slot, and the full insertion is completed in real time, so that the elastic tooth profile is clamped between the corresponding right-angled tooth profiles under the elastic action, and the spring rod is pressed at the same time. After the installation is completed, the push rod is released, and the limit plate is pushed under the tension of the tension spring, so that the push rod returns to the initial position. When disassembling the external component, the elastic tooth profile is separated from the right-angled tooth profile by pulling the connecting block. At this time, the set block is pushed upward by the tension of the spring rod, so that the set block drives the clamped external component to move upward. At this time, the set block is horizontally aligned with the set slot, and then the external component can be pulled out.

[0009] As a further improvement of the above solution, a copper connector is provided in the plug-in slot.

[0010] Through the above technical solution, when the external component is plugged into the plug slot, the copper connector fits into the connection of the plugged external component to achieve data transmission.

[0011] As a further improvement of the above solution, a heat dissipation groove is provided on the side of the plug slot, and the heat dissipation groove is communicated with the inside of the plug slot.

[0012] Through the above technical solution, the air is blown into the plug-in slot through the heat dissipation slot, thereby achieving heat dissipation treatment for the plugged external components.

[0013] As a further improvement of the above solution, a dust filter is fixed in the heat dissipation groove.

[0014] Through the above technical solution, the dust filter plays a role in intercepting and filtering dust, preventing dust from entering the socket slot.

[0015] As a further improvement of the above solution, a limiting piece is fixed on the push rod, and the limiting piece is attached to the plug-in box.

[0016] Through the above technical solution, the diameter of the limiting piece is larger than the diameter of the hole formed by the push rod passing through the plug-in box, and is used to limit the push rod from being separated from the sleeve hole.

[0017] As a further improvement of the above solution, a tension spring is movably sleeved on the side of the push rod, and the tension spring is located between the limiting piece and the plug-in box.

[0018] Through the above technical solution, the tension spring has tension, pushing the limit plate upward, so that the push rod returns to the initial position.

[0019] As a further improvement of the above solution, a stabilizing sleeve rod is fixed to the side of the connecting block, and the stabilizing sleeve rod is movably sleeved in the connecting groove.

[0020] Through the above technical solution, a sleeve hole is opened on the side of the connecting groove opposite to the connecting block, and the stable sleeve rod is sleeved in the sleeve hole, thereby improving the stability of the connecting block in sliding and pulling.

[0021] As a further improvement of the above solution, a right-angle tooth profile is provided in the fitting groove, and an elastic tooth profile is provided on the side of the fitting block, and the elastic tooth profile is engaged with the right-angle tooth profile.

[0022] Through the above technical solution, the elastic tooth profile and the right-angle tooth profile are set in opposite directions to achieve an anti-reverse effect, so that the set block can move downward but cannot move upward. When moving downward, the stuck external component is inserted downward into the deep part of the socket.

[0023] As a further improvement of the above solution, a spring rod is fixed to the bottom of the set block, and one end of the spring rod is fixed in the connecting groove.

[0024] Through the above technical solution, after the set block is separated from the connecting block, the set block moves upward under the tension of the spring rod and returns to its initial position. At this time, the elastic tooth profile on the side re-engages with the right-angle tooth profile at the corresponding position.

[0025] As a further improvement of the above solution, a retaining slot is provided on the retaining protrusion.

[0026] Through the above technical solution, the retaining bayonet is snapped into the bayonet on the side of the corresponding end of the external component to achieve snap-on retention. When the retaining protrusion moves downward, the external component is driven to move downward at the same time.

[0027] Compared with the prior art, the present invention provides a slot-type PCB circuit board with the following beneficial effects:

[0028] 1. The slot-type PCB circuit board has connection slots on both sides of the plug-in box. Retaining pieces are slidably connected in the connection slots to fix the plugged external components. When the retaining pieces are completely in the connection slots, the push rod is pushed downward, so that the set block drives the clamped external components downward and inserts them deep into the plug-in slot. The right-angle tooth profile and the elastic tooth profile are designed to prevent reverse rotation, so that the external components are fully clamped and fixed. This design can ensure the stability of the external component insertion while also ensuring the service life of the retaining pieces.

[0029] 2. The slot-type PCB circuit board can separate the set slot from the set block by pulling the connecting block, that is, the elastic tooth profile is separated from the right-angle tooth profile. Then, under the push of the spring rod, the set block drives the clamped external components upward to separate from the plug-in slot, thereby achieving the effect of rapid disassembly and assembly, further improving its practicality.

[0030] 3. The slot-type PCB circuit board has a heat dissipation slot on the side of the plug-in box that is opposite to the back of the copper connector, allowing air to enter the plug-in slot, which can effectively dissipate heat and cool the interior of the slot and the plugged-in external components, further improving its practicality.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0041] See also Figures 1-6As shown, the slot-type PCB circuit board proposed in this embodiment includes a circuit board 1 and a slot assembly 2. Multiple groups of slot assemblies 2 are fixed on the circuit board 1. External components are connected to the slot assemblies 2 by plugging to realize data transmission and power supply, thereby improving the scalability of the system.

[0042] The slot assembly 2 consists of a plug-in box 21 and a retaining member 22. The plug-in box 21 is fixed on the circuit board 1. A plug-in slot 201 is provided on the plug-in box 21. An external component is plugged into the plug-in slot 201. Push rods 206 are movably sleeved on both ends of the plug-in box 21. At the same time, connecting slots 209 are provided at both ends of the plug-in box 21. The connecting slot 209 is connected to the plug-in slot 201. The push rod 206 passes through the connecting slot 209. An external component of the same model and size is plugged into the plug-in slot 201 to realize the connection between the external component and the circuit board.

[0043] The retaining member 22 includes a connecting block 210 that is movably sleeved in the connecting groove 209, a sleeve groove 212 is provided on the connecting block 210, a sleeve block 213 is movably sleeved in the sleeve groove 212, and a retaining protrusion 216 is provided on the sleeve block 213. The retaining protrusion 216 is used to fix the external component. When the connecting block 210 is completely in the connecting groove 209, the retaining protrusion 216 is clamped on the side of the corresponding end of the external component to fix the plugged external component. When the connecting block 210 slides outward, it is separated from the side of the external component, so that the plugged external component can be taken out.

[0044] The working principle of the slot-type PCB circuit board proposed in this embodiment is as follows: when in use, the external component is plugged into the corresponding plug-in box 21. At this time, the side of the external component is clamped in the retaining clamp 217. By pressing the push rods 206 at both ends of the plug-in box 21, the push rods 206 move downward, pushing the set block 213 to move downward from the set groove 212, so that the retaining protrusion 216 drives the clamped external component to be fully inserted into the deep part of the plug-in slot 201, and the full insertion is completed in real time, so that the elastic tooth profile 219 is clamped in the corresponding right-angle tooth profile 21 under the elastic action. 8, and at the same time, the spring rod 215 is tightened. After the installation is completed, the push rod 206 is released, and under the tension of the tension spring 208, the limit plate 207 is pushed to make the push rod 206 return to the initial position. When disassembling the external component, the elastic tooth profile 219 is separated from the right-angle tooth profile 218 by pulling the connecting block 210. At this time, the tension of the spring rod 215 pushes the set block 213 upward, so that the set block 213 drives the clamped external component to move upward. At this time, the set block 213 is horizontally aligned with the set slot 212, and then the external component can be pulled out. Example 2

The wind is blown into the plug slot 201 through the heat dissipation groove 204 to realize heat dissipation of the plugged external component. The dust filter 205 plays the role of intercepting and filtering dust to prevent dust from entering the plug slot 201. The diameter of the limit plate 207 is larger than the diameter of the hole formed by the push rod 206 passing through the plug box 21, which is used to limit the push rod 206 from being separated from the hole of the sleeve. The tension spring 208 has tension, which pushes the limit plate 207 upward so that the push rod 206 returns to the initial position. A sleeve hole is opened on the side of the connecting groove 209 opposite to the connecting block 210 to firmly fit the sleeve rod 211 In the sleeve hole, the stability of the sliding and pulling of the connecting block 210 is improved. The elastic tooth profile 219 and the right-angled tooth profile 218 are set in opposite directions to achieve an anti-reverse effect, so that the set block 213 can move downward, but cannot move upward.
