Description

Technical Field

[0001] The utility model belongs to the technical field of electric connectors, and in particular relates to an anti-falling structure for a plastic frame. Background Art

[0002] Currently, cables are the mainstream method for transmitting current from copper busbars to the PCB (printed circuit board) inside servers, providing power to various components. The stability and structural strength of the current transmission from the cable end to the PCB are crucial to overall stability. Furthermore, the cable plug-in and unplug ends must remain intact during the plug-in and unplug process to ensure repeated use.

[0003] At present, the outer shell of the cable plug-in end is generally formed by a combination of a cover and a shell. Since the outer shell of the cable plug-in end is generally made of plastic, the plastic frame mouth will shrink and deform during the molding process. At the same time, when plugging and unplugging the cable, the staff generally hold the outer shell of the plug-in end to perform the plug-in and unplug action. Therefore, the cover and the shell will be deformed under force, and combined with the inward deformation of the shell frame mouth, the cover is very easy to fall off from the shell. Utility Model Content

[0004] In view of the above problems in the prior art, the purpose of the present invention is to provide an anti-falling structure for a plastic frame.

[0005] The utility model provides the following technical solutions:

[0006] A structure for preventing a plastic frame from falling off comprises a shell and a cover. The cover is provided with a plurality of snap through holes, and the shell is provided with protrusions corresponding to the snap through holes. The cover is snapped onto the shell by snapping the protrusions with the snap through holes. Notches are symmetrically provided on both sides of the swallow tail of the cover, and protrusions are provided on the edge of the shell corresponding to the notches.

[0007] Specifically, a guide corner 1 is provided at the bottom edge of the notch.

[0008] Specifically, a second guide corner is provided at the top edge of the raised portion.

[0009] Specifically, the structure of the snap through hole is an L-shaped through hole.

[0010] Specifically, a plurality of snap through holes are evenly arranged on the cover.

[0011] An anti-drop structure for a plastic frame includes a shell and a cover. The shell has several side walls to form a terminal accommodating space. The cover is snapped onto the shell to form an outlet. The shell is provided with a protrusion on at least two side walls adjacent to the outlet. The cover is provided with a notch corresponding to the protrusion. When the cover is snapped onto the shell, the protrusion and the notch engage with each other.

[0012] Specifically, a protrusion is provided on at least one side wall.

[0013] Specifically, a snap-fit ​​through hole is provided on the cover corresponding to the protrusion.

[0014] Specifically, a guide corner 1 is provided at the bottom edge of the notch.

[0015] Specifically, a second guide corner is provided at the top edge of the raised portion.

[0016] The beneficial effects of the utility model are:

[0017] After the shell and the cover are fastened together, the frame of the shell can be restricted from left and right deformation and movement with the cooperation of the protrusion and the notch, thereby compensating for the inward deformation and ensuring that the fastening amount of the shell and the cover remains unchanged. At the same time, when using plug-and-play cables, the force on the shell and the cover is supported, thereby suppressing deformation and ensuring the stability of the overall structure.

[0023] like Figures 1 to 3As shown, the present invention provides an anti-drop structure for a plastic frame, comprising a housing 2 and a cover 1. The housing 2 has several sidewalls, thereby forming a terminal accommodation space therein for the terminals to be installed therein. The cover 1 is evenly distributed with a plurality of snap-on holes 8. At least two sidewalls 11 of the housing 2 are provided with protrusions 9 corresponding to the snap-on holes 8. The cover 1 is snapped onto the housing 2 by snapping the snap-on holes 8 with the protrusions 9. When the cover 1 and the housing 2 are assembled, a cable outlet 10 is formed for the passage of cables connected to the terminals. The swallowtail portion 3 of the cover 1 is symmetrically provided with notches 4 on both sides, and a protrusion 5 is provided along the edge of the housing 2 corresponding to the notches 4. The protrusion 5 is preferably located on the sidewall with the protrusion 9, adjacent to the cable outlet. When the cover 1 is snapped onto the housing 2, the protrusion 5 engages with the notch 4, allowing the sidewall position to compensate for deformation during the molding process and maintaining the original design value for the snap-on holes 8 and the protrusion 9, thereby ensuring the stability of the overall structure.

[0024] At present, the shell of the cable plug-in end is formed by a combination of a cover 1 and a shell 2. Since the shell of the cable plug-in end is generally made of plastic, the plastic frame mouth will shrink and deform during the molding process. At the same time, when plugging and unplugging the cable, the staff generally hold the shell of the plug-in end to perform the plug-in and unplug action. Therefore, the cover 1 and the shell 2 will be deformed under force, and combined with the inward deformation of the frame mouth of the shell 2, the cover 1 is very easy to fall off from the shell 2.

[0025] The device is provided with a structure in which the protrusion 5 cooperates with the notch 4 to prevent the frame opening of the shell 2 from shrinking and deforming.

[0026] Furthermore, the structure of the snap through hole 8 is an L-shaped through hole, so that when the cover 1 is pressed and snapped onto the protrusion 9, it can ensure that the deformation of the cover 1 is elastic deformation, thereby avoiding cracks and damage to the side wall of the cover 1.

[0027] Furthermore, a guide corner 1 6 is provided at the bottom edge of the slot 4, and a guide corner 2 7 is provided at the top edge of the protrusion 5. The function of the guide corner 1 6 and the guide corner 2 7 is to guide and direct the movement of the protrusion 5 when the cover 1 is buckled on the shell 2, thereby facilitating the protrusion 5 to be inserted into the slot 4 through the guide corners.

[0028] After the shell 2 and the cover 1 are fastened together, with the cooperation of the protrusion 5 and the notch 4, the frame of the shell 2 can be restricted from left and right deformation and movement, thereby compensating for the inward deformation and ensuring that the fastening amount of the shell 2 and the cover 1 remains unchanged. At the same time, when using plug-and-play cables, the forces on the shell 2 and the cover 1 are supported, thereby suppressing deformation and ensuring the stability of the overall structure.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
