As shown in fig. 1 and 2, the charging adapter 10 of an embodiment includes a plug 100 and a conductive wire 200, and the plug 100 is detachably connected to the conductive wire 200. Plug 100 includes a housing 110. The housing 110 defines a receiving groove 112.

As shown in fig. 1 and 3, in one embodiment, the conductive wire 200 includes a card housing 230, and the card housing 230 is located in the receiving groove 112 and slidably connected to the housing 110. The card shell 230 is further clamped to the housing 110 along a sliding direction relative to the housing 110, so that the clamping position of the card shell 230 to the housing 110 changes during the relative sliding process of the card shell 230 and the housing 110.

When the card housing 230 slides to a predetermined position in a direction of being separated from the housing 110, a portion of the card housing 230 is clamped to the housing 110, and the card housing 230 is pulled out, so that the part of the card housing 230 clamped to the housing 110 is separated. In this embodiment, when the card housing 230 slides to a predetermined position in a direction of separating from the housing 110, the depth of the card housing 230 in the engagement with the housing 110 is shallow, so that a user can pull out the card housing 230, and the card housing 230 is separated from the housing 110 in the engagement. Specifically, when the card shell 230 slides to the predetermined position in the direction of separating from the housing 110, the card shell 230 slides to the limit position in the direction of separating from the housing 110, so that the card shell cannot slide further in the direction of separating from the housing 110, thereby avoiding the problem of separating the card shell 230 from the housing 110.

Referring again to fig. 1, the direction in which the card housing 230 slides with respect to the housing 110 is a first direction, i.e., the X-axis direction shown in fig. 1. The direction in which the card case 230 is drawn out with respect to the housing 110 is a second direction, i.e., a Y-axis direction shown in fig. 1. An included angle exists between the first direction and the second direction. In the present embodiment, the charging adapter 10 is used to charge an electronic device such as a mobile device by commercial power. The plug 100 is plugged into a socket or a power strip connected to a mains supply, and the conductive wire 200 is connected to the plug 100 and the electronic device, so that the plug 100 is electrically connected to the electronic device through the conductive wire 200.

In the charging adapter, because the card shell 230 is located in the receiving groove 112 and slidably connected to the housing 110, the card shell 230 is further fastened to the housing 110 along a sliding direction relative to the housing 110, when the card shell 230 slides to a predetermined position along a direction of fastening and separating from the housing 110, the card shell 230 is pulled out, so that the fastening portion of the card shell 230 and the housing 110 is separated, and because an included angle exists between the first direction and the second direction, that is, the sliding direction of the card shell 230 relative to the housing 110 is different from the pulling direction, a problem that the conductive wire body 210 is accidentally pulled to separate the card shell 230 relative to the housing 110 in the sliding process is avoided, that is, only the sliding operation of the card shell 230 relative to the housing 110 is not to cause the situation of fastening and separating the card shell 230 from the housing 110, thereby avoiding the situation of accidental electric shock, and further improving the safety of the charging adapter 10. Because the card shell 230 cannot be pulled out when the card shell 230 does not slide to the predetermined position relative to the housing 110, and the card shell 230 cannot be pulled out only by the operation of sliding the card shell 230 relative to the housing 110, the card shell 230 and the housing 110 are not easy to be accidentally separated, only when the card shell 230 slides to the predetermined position in the direction of separating the card shell from the housing 110, the user can pull out the card shell 230, and further the card shell 230 and the portion of the housing 110 are separated, thus, the clamping and detaching process between the card shell 230 and the housing 110 is ingenious, the use reliability of the charging adapter 10 is further improved, and the use safety of the charging adapter 10 is also improved; because the clamping part of the card shell 230 and the shell 110 can be separated, the plug 100 and the conductive wire 200 can be detachably connected, and the card shell 230 or the shell 110 can be maintained or replaced in the using process, so that the use convenience of the charging adapter 10 is improved, and the use cost of the charging adapter 10 is reduced.

As shown in fig. 1, in order to make the card housing 230 bear a small resistance in the direction of pulling out relative to the housing 110, in one embodiment, the included angle between the first direction and the second direction is 30 ° to 60 °, so that the card housing 230 bears a small resistance in the direction of pulling out relative to the housing 110, and further, the card housing 230 is pulled out of the housing 110 quickly.

As shown in fig. 1 and fig. 2, in one embodiment, the plug 100 further includes a first abutting portion 120, the first abutting portion 120 is located in the receiving groove 112 and connected to the housing 110, that is, the first abutting portion 120 is exposed in the receiving groove 112, so that the first abutting portion 120 abuts against the conductive wire 200 for conducting electricity. The conductive wire 200 further includes a conductive wire main body 210 and a second interference part 220, and both the conductive wire main body 210 and the second interference part 220 are connected with the card case 230. The conductive wire body 210 is electrically connected to the second interference part 220. The first abutting portion 120 abuts against the second abutting portion 220, so that the first abutting portion 120 is electrically connected with the second abutting portion 220. In this embodiment, when the card housing 230 and the housing 110 are clamped in place, the first abutting portion 120 abuts against the second abutting portion 220, so that the first abutting portion 120 is electrically connected to the second abutting portion 220.

As shown in fig. 4, in one embodiment, the housing 110 further defines a groove 113 and a slot 115, and the receiving slot 112 is respectively communicated with the groove 113 and the slot 115. Referring to fig. 5 and 6, a first boss 232 and a clamping table 234 are convexly disposed on an outer wall of the clamping shell 230, the first boss 232 is located in the groove 113 and moves relative to the housing 110, so that the first boss 232 moves in the groove 113 when the clamping shell 230 slides relative to the housing 110, and the first boss 232 moves relative to the housing 110 in the groove 113, so that the clamping shell 230 does not excessively slide relative to the housing 110, and a limiting effect is achieved. The engaging table 234 is engaged with the engaging groove 115 along a sliding direction of the engaging shell 230 relative to the housing 110. When the card housing 230 slides to a predetermined position in the direction of separating the card platform 234 from the card slot 115, the first boss 232 abuts against the inner wall of the groove 113, the card platform 234 is partially located in the card slot 115, and the card housing 230 is pulled out to separate the card platform 234 from the card slot 115. Since the first boss 232 abuts against the inner wall of the groove 113 when the card case 230 slides to a predetermined position in a direction in which the card table 234 is separated from the card slot 115, the problem that the card case 230 further slides in a direction in which the card table 234 is separated from the card slot 115 is avoided, and thus, the card case 230 cannot be pulled out only by an operation of sliding the card case 230 with respect to the housing 110.

As shown in fig. 6, in one embodiment, the cross section of the clamping platform 234 is arc-shaped, and the clamping platform 234 is adapted to the clamping groove 115, that is, the clamping groove 115 is a groove body with an arc-shaped cross section. When the card shell 230 slides to a predetermined position in the direction of separating from the housing 110, the card platform 234 is pulled out in the second direction relative to the card slot 115, so as to reduce the resistance of the card shell 230 to the pulling-out of the housing 110, and further to quickly separate the card shell 230 from the housing 110.

As shown in fig. 5 and 6, in particular, the card case 230 includes a base 230a and a card case body 230b connected. The conductive wire body 210 is located between the base 230a and the card housing body 230b, and the conductive wire body 210 is connected to the base 230a and the card housing body 230b, respectively, so that the conductive wire body 210 is connected to the card housing 230. The first boss 232 is disposed on the base 230a, and the clamping platform 234 is disposed on the clamping housing body 230b, such that the first boss 232 and the clamping platform 234 are respectively protruded on different positions of the clamping housing 230. The second interference portion 220 is connected to the base 230a, so that the second interference portion 220 is connected to the card housing 230.

As shown in fig. 7, in one embodiment, the base 230a and the card housing body 230b are detachably connected to allow the base 230a and the card housing body 230b to be maintained or replaced. In addition, since the base 230a is detachably connected to the card housing main body 230b, the detachment and installation of the conductive wire main body 210 are facilitated, so that the conductive wire main body 210 can be replaced. In this embodiment, the base 230a is connected with the card housing main body 230b by a snap fit, so that the base 230a and the card housing main body 230b can be quickly disassembled and assembled, and the convenience of the card housing 230 is improved.

As shown in fig. 7 and 8, specifically, the base 230a is convexly provided with a hook 231, the housing main body 230b is provided with an insertion groove 233 and a clearance groove 235, which are communicated with each other, and the hook 231 is inserted into the insertion groove 233, so that the hook 231 is in snap-fit connection with the housing main body 230 b. The conductive wire body 210 is inserted into the avoiding groove 235, and the conductive wire body 210 is compressed between the base 230a and the card housing body 230b, so that the conductive wire body 210 is connected to the base 230a and the card housing body 230b, respectively. Referring to fig. 3, the base 230a is formed with a through hole 236 communicating with the insertion groove 233, and the second interference portion 220 is electrically connected to the conductive wire main body 210 through the through hole 236. In this embodiment, the end portion located in the insertion slot 233 is electrically connected to the second interference portion 220, so that the second interference portion 220 is electrically connected to the conductive wire main body 210, and one end of the conductive wire main body 210 can be accommodated in the card housing 230, thereby making the structure of the charging adapter 10 compact. In this embodiment, the two opposite sides of the base 230a are provided with the hooks 231, so that the base 230a and the card housing body 230b are reliably connected by snapping.

As shown in fig. 8 and 9, in order to firmly clamp the base to the inner wall of the insertion groove and reduce the weight of the card housing main body 230b, the card housing main body 230b is further provided with a bayonet groove 231b communicated with the insertion groove 233, and the end of the hook is located in the bayonet groove. When the hook is buckled into the insertion groove 233 in place, the hook slides into the bayonet groove, so that the hook is limited in the bayonet groove, the problem that the base and the card shell body are easily separated is avoided, the base is firmly clamped on the inner wall of the insertion groove, and the weight of the card shell body 230b is reduced. In this embodiment, the bayonet socket groove runs through the bayonet socket main part, makes the trip expose through the bayonet socket groove to the user dismantles separation base and bayonet socket main part through the bayonet socket groove, has improved the convenience of bayonet socket dismouting.

Referring to fig. 3 again, since the hook 231 is deformed when being fastened in the insertion groove 233, the joint between the hook 231 and the housing main body 230b is broken, in one embodiment, an anti-cracking notch 237 is formed at a position of the hook 231 adjacent to the base 230a, so that the joint between the hook 231 and the housing main body 230b is prevented from being broken, and the service life of the hook 231 is prolonged.

As shown in fig. 3, in one embodiment, the second interference portion 220 is disposed in the through hole 236 and connected to the base 230a, so that the second interference portion 220 is reliably mounted on the base 230a, and the distance between the second interference portion 220 and the base 230a is reduced. In the present embodiment, the second abutting portion 220 is a curved conductive elastic sheet, so that the second abutting portion 220 is inserted into the through hole 236 and reliably connected to the base 230 a.

As shown in fig. 3, a slot 238 is formed in the base 230a and communicates with the through hole 236, and the second abutting portion 220 is further inserted into the slot 238, so that the second abutting portion 220 is firmly connected to the base 230 a. In the embodiment, the second abutting portion 220 is a curved conductive elastic sheet, so that the second abutting portion 220 elastically abuts against the first abutting portion 120. Specifically, the cross section of the second interference portion 220 is U-shaped. In order to make the second abutting portion 220 elastically abut against the first abutting portion 120 better, further, the abutting portion of the second abutting portion 220 and the first abutting portion 120 is a tilted surface sheet structure, so that the second abutting portion 220 elastically abuts against the first abutting portion 120 better.

Because the slot 238 is a narrow slot structure, and the space of the inner cavity of the base 230a is small, and the air flow is not easy to enter the cavity surrounded by the base 230a and the card housing main body 230b, the connection position of the second interference portion 220 and the conductive wire main body 210 in the insertion slot 233 is easy to heat up, which is not beneficial for the charging adapter 10 to better radiate heat, further, the base 230a is provided with a vent 239 communicated with the slot 238, so that the part of the second interference portion 220 inserted into the slot 238 is exposed through the vent 239, and the air flow in the accommodating groove 112 can radiate the second interference portion 220 through the vent 239, thereby improving the heat radiation performance of the second interference portion 220.

As shown in fig. 8 and 10, a first slide rail 231a is protruded from an outer wall of the base 230a, and the first slide rail 231a extends along a direction in which the hook 231 is inserted into the insertion groove 233. A first sliding groove 231b is formed in the card housing main body 230b, and the first sliding rail 231a is located in the first sliding groove 231b and is slidably connected with the card housing main body 230b, so that the hook 231 can be quickly and accurately clamped into the insertion groove 233, and the base 230a and the card housing main body 230b can be quickly disassembled and assembled. In this embodiment, first sliding tray and inserting groove intercommunication make the processing degree of difficulty of first sliding tray lower, have reduced the processing cost of card shell main part.

As shown in fig. 8, it is understood that the first sliding groove may or may not be in communication with the avoiding groove 235. In this embodiment, first sliding tray and keep away position groove 235 intercommunication, further reduced the processing degree of difficulty of first sliding tray, can ensure the structural strength of card shell main part better simultaneously. Accordingly, the difficulty in disposing the first slide rail 231a is reduced.

As shown in fig. 6 and 10, a second sliding groove 232a is formed in an outer wall of the base 230a, a second sliding rail 232b is convexly formed in the card housing main body 230b, the second sliding rail 232b is located in the second sliding groove 232a and is slidably connected with the base 230a, and the first sliding rail 231a is slidably matched with the first sliding groove 231b, so that the hook 231 can be quickly and accurately clamped into the insertion groove 233. In the present embodiment, the extending direction of the second slide rail 232b is parallel to the extending direction of the first slide rail 231 a. The second slide rail 232b is positioned in the insertion groove, so that the strength of the inner wall of the insertion groove of the card shell main body is enhanced.

Referring to fig. 6 again, further, the conductive wire main body 210 is convexly provided with a positioning column 212, the base 230a is provided with a positioning groove 234a communicated with the insertion groove 233, and the positioning column 212 is located in the positioning groove 234a, so that the conductive wire main body 210 is positioned in the positioning groove 234a, and the conductive wire main body 210 is prevented from being separated from the card housing 230 when being pulled by an external force, which is beneficial to reliably pressing the conductive wire main body 210 between the base 230a and the card housing main body 230 b. In the present embodiment, the positioning pillars 212 are protruded from the conductive line body 210 toward a side close to the base 230 a. The positioning post 212 is in interference fit with the positioning groove 234a, so that the positioning post 212 elastically abuts against the positioning groove 234a, and the positioning post 212 is firmly connected with the base 230 a. Furthermore, the positioning post 212 is an elastic rubber post structure, so that the positioning post 212 has better elasticity in the positioning groove 234a in an interference fit manner, and the connection between the positioning post 212 and the base 230a is firmer.

It is understood that the hardness of each portion of the positioning post 212 may be different or the same.
