Description

Technical Field

[0001] This utility model relates to the field of electronic plug-in technology, and in particular to a profile guide rail structure for electronic plug-in. Background Technology

[0002] Guide rails and PCB board slot guides are structural components in rail transit, power, and communication equipment, and can be used in matching chassis structures. General guide rail profiles are designed with an open structure due to processing limitations and installation requirements; that is, the guide rail is open along its length. This facilitates the processing of the guide rail's inner groove and the fitting of the guide head with the inner groove. However, this structure significantly affects the strength of the guide rail profile itself, so it is changed from an open structure to a fully enclosed structure, meaning the inner groove of the guide rail is completely closed circumferentially.

[0003] However, because of the fully enclosed guide rail structure, it lacks the advantage of open plug-in connection. Therefore, the plug-in connection structure between the guide head and the guide rail needs further optimization. There is an urgent need for a plug-in connection structure that is compatible with it and easy to use. Utility Model Content

[0004] The purpose of this utility model is to provide a profile guide rail structure for electronic plug-in, so as to solve the problem that there is no suitable and convenient plug-in connection structure between the fully enclosed plug-in guide rail and the guide head.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An electronic plug-in profile guide rail structure includes a guide rail and a guide head. A connecting structure is provided between the guide rail and the guide head. The connecting structure includes a spring element, an anti-detachment plate, a recessed groove on the guide head plug, a release hole and an anti-detachment groove at the end of the guide rail. The spring element and the anti-detachment plate are both placed in the recessed groove. The spring element presses the anti-detachment plate against the anti-detachment groove. The release hole communicates with the anti-detachment groove.

[0006] A further technical solution is that the slide of the guide rail and the cross-section of the plug are both cross-shaped.

[0007] A further technical solution is that the elastic element is a V-shaped spring.

[0008] A further technical solution is that the release hole is located near the outer end of the anti-detachment groove.

[0009] A further technical solution is that the sum of the minimum heights of the elastic element and the anti-detachment plate is greater than the depth of the sinking groove, and less than the distance between the sinking groove and the inner top surface of the guide rail slide.

[0010] A further technical solution is that the sum of the maximum heights of the elastic element and the anti-detachment plate is greater than the sum of the heights of the sink and the anti-detachment groove.

[0011] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This utility model proposes a profile guide rail structure for electronic plug-in components. The traditional open guide rail structure is changed to a fully enclosed guide rail structure. On the basis of increasing the strength of the guide rail, the plug-in connection structure between the guide head and the guide rail is optimized. With the help of elastic elements, the anti-detachment plate is pressed tightly into the anti-detachment groove. The anti-detachment plate is located between the recess and the anti-detachment groove, which can prevent the guide head from going into the guide rail but not backing out. When replacing or disassembling, a tool is used to push the anti-detachment plate back into the recess through the release hole, and the guide head can be pulled out to complete the operation. The operation is simple and simplifies the structure of the guide rail and the guide head itself. Attached Figure Description

[0023] This implementation example Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an electronic plug-in profile guide rail structure includes a guide rail 1 and a guide head 2. A connecting structure is provided between the guide rail 1 and the guide head 2. The connecting structure includes a spring member 3, an anti-detachment plate 4, a recessed groove 5 provided on the plug of the guide head 2, a release hole 6 and an anti-detachment groove 7 provided at the end of the guide rail 1. The spring member 3 and the anti-detachment plate 4 are both placed in the recessed groove 5. The spring member 3 presses the anti-detachment plate 4 against the anti-detachment groove 7. The release hole 6 communicates with the anti-detachment groove 7.

[0024] During assembly, the elastic element 3 and the anti-detachment plate 4 are first placed into the recessed groove 5 on the guide head 2 plug. Then, the plug is inserted into the slide (slot) of the guide rail 1. Once in place, the anti-detachment plate 4 is pushed into the anti-detachment groove 7 of the guide rail 1 by the elastic element 3. At this time, the anti-detachment plate 4 is between the recessed groove 5 and the anti-detachment groove 7, which plays a role in preventing the guide head 2 from retracting from the guide rail 1. During disassembly, the PCB board and other components are first removed. Then, when disassembling the guide head 5, a tool such as a screwdriver is used to push the anti-detachment plate 4 back into the recessed groove 5 through the release hole 6. The guide head 5 can then be pulled out to complete the disassembly. The operation is simple and simplifies the structure of the guide rail 1 and the guide head 2 itself.

[0025] Preferably, the cross-section of both the slide rail 1 and the plug is cross-shaped.

[0026] The cross-shaped sliding structure distributes the force evenly on all four sides, ensuring stable sliding and high strength. Example

[0027] Based on the above embodiments, this embodiment shows that the elastic element 3 is a V-shaped spring. The release hole 6 is located near the outer end of the anti-detachment groove 7.

[0028] The V-shaped spring is placed in the recess 5, ensuring that the tail faces outward and the head faces inward towards the guide rail 1. This causes the anti-detachment plate 4 to be in a state where the tail is raised and the head is lowered, thus facilitating the guide head 2 to move in easily but not backward. It also makes disassembly easier.

[0029] Preferably, the sum of the minimum heights of the elastic element 3 and the anti-detachment plate 4 is greater than the depth of the sink 5 and less than the distance between the sink 5 and the inner top surface of the guide rail 1. The sum of the maximum heights of the elastic element 3 and the anti-detachment plate 4 is greater than the sum of the heights of the sink 5 and the anti-detachment groove 7.

[0030] Ensure that the head of the anti-detachment plate 4 can smoothly enter the guide rail 1, and that the tail of the anti-detachment plate 4 can be pressed against the anti-detachment groove 7, so as to achieve the effect of easy entry but not easy exit.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
