Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to an output line component used for a power adapter. Background Art

[0002] A power adapter is a power conversion device used to convert the voltage and current of a power source into a specific output voltage and current for use by other electronic devices. A general power adapter consists of a power adapter body, a power input line, and a power output line. The power adapter body mainly includes a housing and a PCB circuit board and other electronic components inside the housing.

[0003] For example, announcement number CN213342033U discloses a power adapter, which includes: a box body component and a power conversion component, the power conversion component is accommodated in the box body component, the box body component is respectively provided with an input connector and an output line, the input connector is electrically connected to the input end of the power conversion component, the output line is electrically connected to the output end of the power conversion component, and one end of the output line is provided with an output connector that can be engaged with an electrical appliance connector; an anti-pull buckle is pivotally connected to the output connector, and a bayonet is provided at the front end of the anti-pull buckle; after the output connector is engaged with the electrical appliance connector, the anti-pull buckle can rotate and make the bayonet clamp the clamping protrusion on the electrical appliance connector; the box body component is provided with a hanging ear, and the bayonet of the anti-pull buckle can also clamp the hanging ear. The above technical solution mainly solves the problem that the output line of the power adapter cannot be fixed at the connection between the box body and the output connector; it has a compact structure and cleverly avoids the problem of the output connector swinging around and the messy output line.

[0004] However, the technical solution disclosed in the above patent still has the following problems: the technical solution requires the narrowing part to be accurately inserted into the notch and kept fixed before the upper shell and the lower shell can be assembled, which makes the assembly process more complicated and the assembly efficiency is low. In addition, the structural coordination between the protrusion and the notch is relatively simple, that is, the structural coordination between the cylindrical outer contour of the narrowing part and the circular notch, and the connecting seat is not provided with an anti-rotation structure. Therefore, when the other end of the output line is pulled or swung, it is easy to cause the narrowing part of one end of the output line to shake or rotate relative to the notch. In severe cases, the protrusion is deformed, loosened or broken, causing the connecting seat to fall off from the notch of the box body.

[0005] Therefore, there is an urgent need for a structure or device that can effectively improve the connection stability and assembly efficiency of the output line and the housing. Utility Model Content

[0011] In one embodiment, the connector is an integrally formed structure.

[0013] In one embodiment, a plug-in end is formed at one end of the rubber-coated body, and the plug-in end is plugged into the plug-in port. A rubber-coated end is formed at the other end of the rubber-coated body. An annular limiting portion is provided between the plug-in end and the rubber-coated end. The cross-sectional area of ​​the annular limiting portion is larger than the opening area of ​​the plug-in port, and the annular limiting portion is used to abut against the outer wall of the shell.

[0014] In one of the embodiments, the plug-in end is provided with a plug-in cavity, and the plug-in cavity is used to fix the female terminal at one end of the output line to be connected with the male terminal of the PCB board, and the female terminal is exposed in the plug-in cavity.

[0015] In one of the embodiments, a curved portion is formed at one end of the rubber-coated end away from the annular limiting portion, and a plurality of pressure-reducing grooves are arranged around the surface of the curved portion.

[0021] 1. The rubber-coated main body is directly plugged into the plug interface, replacing the existing fixed connection structure between the output line and the adapter shell, thereby optimizing the assembly structure and assembly sequence of the output line and the adapter shell, and effectively improving the assembly efficiency of the output line to the shell.

[0022] 2. Since the rubber-coated main body is molded on one end of the output line, when the rubber-coated main body is connected to the plug interface, the first inverted anti-detachment portion and the second inverted anti-detachment portion can respectively abut against the inner wall of the shell, thereby ensuring that when the other end of the output line is pulled, one end of the output line and the plug interface still have good connection stability.

[0030] The present disclosure provides an output line assembly 10, which is used in the plug interface 101 of the housing 100 of the adapter. The output line assembly 10 also includes an output line 200 and a plug connector 300. The female terminal at one end of the output line 200 is used to electrically connect to the PCB board in the adapter. The plug connector 300 includes a rubber-coated body 310, a first inverted anti-detachment portion 320 and a second inverted anti-detachment portion 330 arranged on both sides of the rubber-coated body 310, the rubber-coated body 310 is rubber-coated and molded at one end of the output line 200, and part of the connecting terminal is exposed on the surface of the rubber-coated body 310, the rubber-coated body 310 is plugged into the plug interface 101, the first inverted anti-detachment portion 320 extends along a first direction, and the second inverted anti-detachment portion 330 extends along a second direction, and the first direction and the second direction are arranged at a preset angle, so that the first inverted anti-detachment portion 320 and the second inverted anti-detachment portion 330 are respectively abutted against the inner side wall of the housing 100.

[0031] See also Figures 1 to 3 In order to better understand the output line assembly 10 of the present application, the output line assembly 10 is further explained below:

[0032] An output line assembly 10 of one embodiment is used in a plug-in port 101 of a housing 100 of an adapter. The output line assembly 10 also includes an output line 200 and a plug connector 300. The female terminal at one end of the output line 200 is used to electrically connect to a PCB board in the adapter. The plug connector 300 includes a rubber-coated body 310, a first inverted anti-detachment portion 320 and a second inverted anti-detachment portion 330 arranged on both sides of the rubber-coated body 310, the rubber-coated body 310 is rubber-coated and molded at one end of the output line 200, a portion of the connection terminal is exposed on the surface of the rubber-coated body 310, the rubber-coated body 310 is plugged into the plug-in port 101, the first inverted anti-detachment portion 320 extends along a first direction, and the second inverted anti-detachment portion 330 extends along a second direction, and the first direction and the second direction are arranged at a preset angle, so that the first inverted anti-detachment portion 320 and the second inverted anti-detachment portion 330 are respectively abutted against the inner side wall of the housing 100.

[0033] In this embodiment, the rubber-coated main body 310 is directly plugged into the plug port 101, replacing the existing fixed connection structure between the output line 200 and the adapter housing 100, thereby optimizing the assembly structure and assembly sequence of the output line 200 and the adapter housing 100, and effectively improving the assembly efficiency of the output line 200 in the housing 100.

[0034] Furthermore, since the rubber-coated main body 310 is rubber-coated and molded on one end of the output line 200, when the rubber-coated main body 310 is connected to the plug interface 101, the first inverted anti-detachment portion 320 and the second inverted anti-detachment portion 330 can respectively abut against the inner wall of the shell 100, thereby ensuring that when the other end of the output line 200 is pulled, there is still good connection stability between one end of the output line 200 and the plug interface 101.

[0035] like Figure 1 As shown, in one embodiment, the connector 300 is an integrally formed structure. It is understandable that the integrally formed structure can make the connector 300 have a good structural connection strength, and also facilitate the one-step injection molding of the connector 300, effectively improving the manufacturability of the connector 300.

[0036] like Figures 1 to 3 As shown, in one embodiment, the preset angle is 30°-60°. It can be understood that, by setting the preset angle, the first undercut anti-detachment portion 320 and the first undercut anti-detachment portion 320 can be more reasonably and reliably abutted against the inner wall of the housing 100, effectively ensuring the plugging stability of the connector 300.

[0037] It should be noted that if Figure 3 As shown, the first direction is the direction of the X arrow, and the second direction is the direction of the Y arrow.

[0038] like Figures 1 to 3 As shown, in one embodiment, a plug-in end 3110 is formed at one end of the rubber-coated body 310, and the plug-in end 3110 is plugged into the plug-in port 101, and a rubber-coated end 3120 is formed at the other end of the rubber-coated body 310, and an annular limiting portion 3130 is provided between the plug-in end 3110 and the rubber-coated end 3120, and the cross-sectional area of ​​the annular limiting portion 3130 is larger than the opening area of ​​the plug-in port 101, and the annular limiting portion 3130 is used to abut against the outer wall of the shell 100. It can be understood that since the cross-sectional area of ​​the annular limit portion 3130 is larger than the opening area of ​​the plug interface 101, and the annular limit portion 3130 abuts against the outer wall of the shell 100, after the plug end 3110 is fully inserted into the plug interface 101, the annular limit portion 3130 can cover the excess gap around the edge of the plug interface 101, effectively preventing dust from entering the interior of the shell 100, while also improving the aesthetics of the shell 100.

[0039] like Figure 3 As shown, in one embodiment, the plug end 3110 is provided with a plug cavity 311a, and the plug cavity 311a is used to fix the female terminal at one end of the output line 200 to be connected with the male terminal of the PCB board, and the female terminal is exposed in the plug cavity 311a. It can be understood that in actual use, a metal connector capable of connecting the female terminal with the male terminal can be set in the plug cavity 311a, that is, the female terminal (the female terminal can be a copper wire) at one end of the output line 200 is connected to one end of the metal connector, and the male terminal of the PCB board is plugged with the jack at the other end of the metal connector, thereby realizing the electrical connection between the female terminal at one end of the output line 200 and the male terminal of the PCB board.

[0040] like Figures 1 to 3 As shown, in one embodiment, a curved portion 3121 is formed at one end of the rubber-coated end 3120 away from the annular limiting portion 3130, and a plurality of decompression grooves 3121a are arranged around the surface of the curved portion 3121. It can be understood that the decompression grooves 3121a can improve the bending toughness of the curved portion 3121, reduce the stress concentration when the curved portion 3121 is bent, thereby improving the bending ability of the connection between the output line 200 and the housing 100, and effectively ensuring the connection stability of the output line 200 at the connection.

[0041] like Figure 2As shown, in one embodiment, the housing 100 includes an upper housing 110 and a lower housing 120, and the upper housing 110 is detachably connected to the lower housing 120. It can be understood that, specifically, the upper housing 110 and the lower housing 120 can be screw-fixed or snap-fitted, which can effectively ensure the convenience and reliability of the assembly connection between the upper housing 110 and the lower housing 120.

[0042] like Figures 1 to 3 As shown, in one embodiment, the periphery of the plug port 101 is chamfered. It is understandable that the chamfered periphery of the plug port 101 provides a guide for the plug port 101 so that the plug end 3110 can be smoothly and accurately inserted into the plug port 101.

[0043] like Figures 1 to 3 As shown, in one embodiment, the top of the plug end 3110 is formed with an anti-fool convex portion 3114, the anti-fool convex portion 3114 is located inside the adapter, and the anti-fool convex portion 3114 abuts against the inner side walls of the upper shell 110 and the lower shell 120. It can be understood that when the plug end 3110 is fully inserted into the plug port 101, the anti-fool convex portion 3114 can reliably abut against the inner side wall of the upper shell 110, and the first inverted anti-detachment portion 320 and the second inverted anti-detachment portion 330 also abut against the inner side wall of the upper shell 110 and the inner side wall of the lower shell 120 respectively, and form a clamping force on the inner and outer walls of the upper shell 110 and the lower shell 120 with the annular limiting portion 3130, which effectively improves the connection stability of the plug end 3110 with the upper shell 110 and the lower shell 120.

[0044] It should be noted that the foolproof protrusion 3114 is not limited to being arranged on the top of the plug end 3110. It can be understood that the foolproof protrusion 3114 can effectively ensure that the plug end 3110 can only be inserted forwardly, but not backwardly, thereby improving the safety of the plug connector 300.

[0045] like Figures 1 to 3 As shown, in one embodiment, the first inverted anti-detachment portion 320 and the second inverted anti-detachment portion 330 are symmetrically arranged along the structural center line of the extension direction of the anti-fool convex portion 3114. It can be understood that the first inverted anti-detachment portion 320 and the second inverted anti-detachment portion 330 are symmetrically arranged, so that the plug end 3110 has a better structural connection stability, effectively preventing the plug connector 300 from falling off from the plug interface 101, ensuring the connection stability of the plug connector 300, that is, ensuring the connection stability between one end of the output line 200 and the housing 100.

[0046] Compared with the prior art, the present invention has at least the following advantages:

[0047] 1. The rubber-coated main body is directly plugged into the plug interface, replacing the existing fixed connection structure between the output line and the adapter shell, thereby optimizing the assembly structure and assembly sequence of the output line and the adapter shell, and effectively improving the assembly efficiency of the output line to the shell.

[0048] 2. Since the rubber-coated main body is molded on one end of the output line, when the rubber-coated main body is connected to the plug interface, the first inverted anti-detachment portion and the second inverted anti-detachment portion can respectively abut against the inner wall of the shell, thereby ensuring that when the other end of the output line is pulled, one end of the output line and the plug interface still have good connection stability.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
