Description

Technical Field

[0001] This utility model relates to the field of computer power cords, and more particularly to an anti-detachment computer power cord plug and a computer power supply for the aforementioned anti-detachment computer power cord plug. Background Technology

[0002] Currently, most computer power cords on the market do not have dedicated locking screws for securing the power cord. Only some graphics card cables have two screws on both sides of the plug to ensure a stable connection between the plug and the socket. This can effectively prevent power outages when moving the monitor. However, in actual use of the computer, power outages often occur suddenly due to moving or shaking the host, thus reducing the user experience.

[0003] Chinese patent document CN213425385U discloses a connecting cable with an anti-detachment structure, including a connector and a protective mechanism. A connector head is installed at the center of the bottom end of the connector, and connector parts are connected to the upper two sides of the connector. An embedding groove is provided at the center of the top of each connector, and a threaded rod is embedded in the inner wall of the embedding groove. A threaded head is connected to the bottom end of the threaded rod, and a first rotating shaft is installed at the center of both sides of the connector. This connecting cable with an anti-detachment structure has a connector, and the connector forms a threaded connection through the embedding groove, the threaded rod, and the threaded head. Because the threaded rods of the aforementioned patent-disclosed connecting cable are located on both sides of the connector head, two threaded rods are typically screwed into the outer shell of the machine body to fix the connecting cable. This requires that the strokes of the two threaded rods be basically the same for a stable connection. Furthermore, because the space on both sides of the connector head is limited, and the diameter of the hand-tightening portion of the threaded rod is also small, tightening is very inconvenient. Utility Model Content

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by this utility model is to propose an anti-detachment computer power cord plug, which can effectively pull the power cord plug to prevent it from coming off. When screwed in to a certain depth, it can play a fixing role. After that, it has low dependence on the length of the screwing stroke and is more convenient to screw in.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides an anti-detachment computer power cord plug, including a plug-in part and a handle part. The plug-in part is fixed to one end of the handle part. It also includes a screw mounting plate and a hand-tightening screw. The screw mounting plate is fixed to the handle part. The handle part includes a limiting part and a wedge-shaped part. One end of the plug-in part is fixedly connected to the limiting part. The other end of the limiting part is connected to one end of the wedge-shaped part. The screw mounting plate is fixed above the limiting part and extends away from the limiting part. The screw mounting plate is close to the grounding interface of the plug-in part. The screw mounting plate is provided with a limiting hole adapted to the hand-tightening screw.

[0007] A preferred embodiment of this invention is that a washer is provided on the side wall of the screw mounting plate, and a through hole corresponding to the limiting hole is provided in the middle of the washer, so that the screw of the hand-tightening screw can pass through the limiting hole and the through hole.

[0008] A preferred embodiment of this invention is that the thickness of the washer ring is less than or equal to the thickness of the abutting portion of the socket that is compatible with the plug portion.

[0009] The preferred technical solution of this utility model is that the screw mounting plate includes a trapezoidal part and a semicircular part, the semicircular part is located above the trapezoidal part, and the center of the semicircular part is configured as the center of the limiting hole.

[0010] A preferred embodiment of this invention is that the inner side of the limiting part is coplanar with the inner side of the screw mounting plate.

[0011] The preferred technical solution of this utility model is that the hand-tightening screw includes a screw body and a screw cap, and the screw cap is fixed to the screw head of the screw body.

[0012] The preferred technical solution of this utility model is that the diameter of the screw cap is greater than or equal to the diameter of the screw head, the screw head is embedded in the screw cap, and the diameter of the screw cap is configured to be 0.8 to 1.5 cm.

[0013] The preferred technical solution of this utility model is that the screw cap is configured as a hollow cylinder with a circular hole inside, the screw head is embedded in the wall of the circular hole, and the screw body extends out of the circular hole by a predetermined distance.

[0014] The preferred technical solution of this utility model is that the outer surface of the screw cap is provided with several anti-slip ridges.

[0015] This utility model also provides a computer power supply, including the aforementioned anti-dislodge computer power cord plug, socket, and housing. The socket is plugged into the anti-dislodge computer power cord plug. The socket is located inside the housing. The abutting part of the socket extends from the mounting opening on the side wall of the housing. A screw hole corresponding to the limiting hole of the hand-tightening screw is provided above the abutting part. The screw of the hand-tightening screw can pass through the limiting hole and be screwed into the screw hole.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model provides an anti-dislodge computer power cord plug with a screw mounting plate for easy screwing in of a hand-tightening screw. The screw mounting plate is fixed above the handle and extends away from the limiting part. Due to gravity, the anti-dislodge computer power cord plug is usually subjected to a downward pulling force from the power cable. The screw mounting plate above the plug effectively counteracts this downward pulling force, making the plug difficult to pull out. Because the screw mounting plate extends away from the limiting part, i.e., upwards, there is more space above it, unlike existing technologies which are limited by the space on both sides of the connector. Therefore, it can accommodate larger diameter hand-tightening screws. Furthermore, once the hand-tightening screw is screwed in to a certain depth, it achieves a fixing effect, and its subsequent screwing stroke is less dependent on the length of the screwing stroke, unlike existing technologies which require the screwing strokes at both ends to be close.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figures 1 to 6As shown, the anti-dislodge computer power cord plug provided in this embodiment includes a plug portion 11, a handle portion 12, a screw mounting plate 13, and a hand-tightening screw 2. The screw mounting plate 13 is tightened by the hand-tightening screw 2. The screw mounting plate 13 is connected to the housing 4 to prevent the anti-dislodge computer power cord plug from shaking or being unnecessarily pulled out. The plug portion 11 is fixed to one end of the handle portion 12, and the screw mounting plate 13 is fixed to the handle portion 12. The handle portion 12 includes a limiting portion 121 and a wedge-shaped portion 122. One end of the plug portion 11 is fixedly connected to the limiting portion 121, and the other end of the limiting portion 121 is connected to one end of the wedge-shaped portion 122. The wedge-shaped portion 122... The other end is connected to the power cable 5. The screw mounting plate 13 is fixed above the limiting part 121 and extends away from the limiting part 121, that is, it extends above the limiting part 121 and away from the anti-detachment computer power cord plug. This makes the screw mounting plate 13 no longer limited by the shape of the anti-detachment computer power cord plug, and has enough space to fit the larger hand-tightening screw 2. Preferably, the diameter range of the screw cap 22 of the hand-tightening screw 2 provided in this application is configured to be 0.8 to 1.5 cm. The larger diameter generates greater torque and is easier to hand-tighten, unlike the limitation of "space on both sides of the connector" in the prior art. The screw mounting plate 13 is located near the ground wire interface 111 of the plug-in part 11. The ground wire interface 111 is located at the top of the plug-in part 11, and the neutral wire interface and the live wire interface are respectively located on its lower two sides. The screw mounting plate 13 is provided with a limiting hole 131 that matches the hand-tightening screw 2. Due to gravity and the natural drooping of the power cable 5, the anti-dislodge computer power cord plug is usually subjected to a downward pulling force from the power cable 5. At this time, the screw mounting plate 15 located above the anti-dislodge computer power cord plug is fixed, which effectively counteracts the downward pulling force from the power cable 5, making it difficult for the anti-dislodge computer power cord plug to be pulled out. In addition, once the hand-tightening screw is screwed in to a certain depth, it can achieve a fixing effect. After that, it has low dependence on the length of the screwing stroke, unlike the limitation in the prior art that "the screwing stroke at both ends must be approximately or equal", which would otherwise make it more prone to poor contact problems.

[0029] To ensure that the length direction of the hand-tightening screw 2 is as perpendicular as possible to the cross-section of the limiting hole 131 when the limiting hole 131 of the screw mounting plate 13 is screwed in, if the screw mounting plate 13 is made too thick, it will prevent the screw mounting plate 13 from swinging slightly to adjust the allowance of the threaded connection, which is not conducive to screwing in the hand-tightening screw 2. Therefore, the screw mounting plate 13 provided in this embodiment is provided with a washer 132 on its side wall. The washer 132 has a through hole in its middle corresponding to the limiting hole 131. The screw 212 of the hand-tightening screw 2 can pass through the limiting hole 131 and the through hole. Preferably, the thickness of the washer 132 is less than or equal to the thickness of the abutment part 31 of the socket 3 that is adapted to the plug-in part 11, so as to ensure that the screw mounting plate 13 does not deflect and is more convenient to be adapted to the hand-tightening screw 2. Therefore, by setting the washer ring 132, the thickness of the screw mounting plate 13 does not need to be too thick. At the same time, the screw mounting plate 13 will not be unable to smoothly connect the hand screw 2 to the screw mounting plate 13 due to the large deflection of the screw mounting plate 13 caused by the protrusion of the abutment part 31.

[0030] Since the distance the abutment portion 31 extends from the mounting port 41 is uncertain, the screw mounting plate 13 is preferably made of plastic material that can deflect slightly. The screw mounting plate 13 includes a trapezoidal portion 133 and a semicircular portion 134. The semicircular portion 134 is located above the trapezoidal portion 133, and the center of the semicircular portion 134 is configured to be the center of the limiting hole 131. This ensures that while maintaining the structural strength of the limiting hole 131, the top of the screw mounting plate 13 is as small as possible, which makes it easier for the screw mounting plate 13 to deflect slightly to accommodate the screwing in of the hand-tightening screw 2. More preferably, the inner side of the limiting portion 121 is coplanar with the inner side of the screw mounting plate 13. The mounting position of the screw mounting plate 13 should be as close as possible to the side wall of the housing 4 and located on the maximum outer diameter of the anti-detachment computer power cord plug, that is, on the limiting portion 121, because the limiting portion 121 is the most convex.

[0031] To facilitate tightening the hand-tightening screw 2, the hand-tightening screw 2 further includes a screw body and a screw cap 22. The screw cap 22 is fixed to the screw head 211 of the screw body. The screw head 211 is provided with a cross-shaped cutting edge, which can be used with a screwdriver when it is difficult to tighten by hand. Preferably, the diameter of the screw cap 22 is greater than or equal to the diameter of the screw head 211, and the screw head 211 is embedded in the screw cap 22. The diameter of the screw cap 22 is configured to be 0.8 to 1.5 cm. The screw cap 22 is configured as a hollow cylinder with a circular hole 221 inside. The screw head 211 is embedded in the wall of the circular hole 221, and the screw shank 212 of the screw body extends out of the circular hole 221 and extends by a preset distance. The preset distance can be reasonably customized according to different customers' products. This embodiment does not limit its specific length. To increase the friction during the tightening process, it is further preferred that the outer surface of the screw cap 22 is provided with several anti-slip ridges 222.

[0032] Example 2

[0033] like Figure 6 As shown, the computer power supply provided in this embodiment includes the aforementioned anti-detachment computer power cord plug, socket 3, and housing 4. The socket 3 is plugged into the anti-detachment computer power cord plug. The socket 3 is located inside the housing 4. The abutment part 31 of the socket 3 extends from the mounting port 41 on the side wall of the housing 4. A screw hole 42 corresponding to the limiting hole 131 of the hand-tightening screw 2 is provided above the abutment part 31. The screw 212 of the hand-tightening screw 2 can pass through the limiting hole 131 and be screwed into the screw hole 42. The anti-detachment computer power cord plug provided in this embodiment has a screw mounting plate 13 that can effectively hold the power cord plug to prevent it from coming off. When the hand-tightening screw 2 is screwed into a certain depth, it can play a fixing role. After that, the dependence on the length of the screwing stroke is low. That is, it is not required that the hand-tightening screw 2 be screwed into the tightest position to achieve the purpose of preventing detachment. Moreover, the hand-tightening screw 2 has a large diameter and is easier to screw in.

This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
