Description

Technical Field

[0001] This utility model relates to a male plug power cord, and more particularly to a hanging structure for a male plug power cord. Background Technology

[0002] A male plug power cord typically refers to a power cord with a male plug on one end and a female plug on the other end, or one that can be directly connected to equipment. It is mainly used for power access to electrical equipment.

[0003] Existing plug power cords, such as the DC connector with a bendable plug disclosed in the Chinese Patent Database (application number: 201820624115.1), include a DC plug, a connecting wire, and an insulating shell for encapsulating the DC plug and the connecting wire. The insulating shell is L-shaped, with the DC plug connected to one end and the connecting wire connected to the other end. The connecting wire includes a live wire and a neutral wire. The DC plug is provided with a terminal block, which has a first terminal for connecting to the live wire and a second terminal for connecting to the neutral wire. The connecting wire is provided with a binding elastic element, which has multiple positioning holes evenly spaced for positioning the connecting wire. The insulating shell is also provided with a magnetic box, and a magnet is provided inside the magnetic box.

[0004] In certain operating conditions, the plug needs to be unplugged when not in use, and to prevent it from dragging on the ground, it generally needs to be suspended. In the connectors mentioned above, the plug can be suspended and positioned by magnetic attraction, but this method requires a magnetically conductive environment, which is not only limited but also requires an additional box to install the magnet, making the structure relatively complex. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a simple and practical hanging structure for male plug power cords.

[0006] The objective of this utility model can be achieved through the following technical solution: a hanging structure for a male plug power cord, including a plug body, the plug body including an L-shaped insulating shell, the insulating shell consisting of a horizontally arranged electrical connection part and a vertically arranged wire introduction part, the electrical connection part consisting of an insertion section and a transition section, and the rear end of the insertion section is connected to the wire introduction part through the transition section, the front end of the insertion section has a horizontally formed insertion post, and a ring-shaped limiting seat is formed at the connection between the insertion section and the transition section, and the limiting seat and the electrical connection part are coaxially arranged; the characteristic is that the outer diameter of the transition section is smaller than the outer diameter of the insertion section, the top wall of the transition section is integrally formed with a long strip block, the long strip block has a strip groove that runs through the thickness direction of the long strip block, and the length extension direction of the long strip block, the electrical connection part and the strip groove are consistent; the front end of the long strip block extends to the limiting seat, and both ends of the strip groove are closed.

[0007] When in use, insert the insertion section of the plug body into the socket of the female plug to make the plug body and the female plug electrically connected. Then, pass the cable tie through the strip groove and suspend and position the plug body on the frame or other components to prevent the plug body from falling after being pulled out.

[0008] This application uses a strip groove formed on the top of the plug body and a cable tie to suspend and position the entire plug body. This not only simplifies the structure but also makes the method more adaptable to various working conditions and more practical.

[0009] Meanwhile, placing the long strip on the transition section with a smaller outer diameter can reduce the space occupied by the plug body, and the long strip also acts as a reinforcing rib to compensate for the reduction in strength caused by the reduction in the outer diameter of the transition section, so as to ensure the overall strength of the insulating shell.

[0010] In the aforementioned male plug power cord holding structure, an inverted U-shaped reinforcing part is also formed on the outer wall of the transition section. The reinforcing part is coaxially arranged with the electrical connection part and is located on the rear side of the long strip to further enhance the strength of the transition section.

[0011] In the aforementioned male plug power cord holding structure, the rear end of the long strip extends to the reinforcing part.

[0012] In the aforementioned hanging structure for the male plug power cord, the long strip also has a circular hole that runs through the thickness of the strip. In actual use, the circular hole can be used with a hanging rope to suspend the plug body, increasing the ways to suspend the plug body and improving its practicality.

[0013] In the aforementioned male plug power cord holding structure, the round hole is positioned between the strip groove and the reinforcing part, with the round hole close to the reinforcing part, to ensure the strength of the long strip and to more stably suspend the plug body.

[0014] In the aforementioned male plug power cord holding structure, a metal tube is horizontally embedded within the elongated block, and the inner hole of the metal tube is the aforementioned circular hole. By embedding a metal tube within the elongated block to form a circular hole, the compressive strength of the circular hole can be improved, allowing for a more stable suspension of the plug body. Furthermore, the circular hole becomes more wear-resistant, extending the service life of the plug body.

[0015] In the aforementioned male plug power cord holding structure, the metal tube and the insulating shell are formed into a whole through injection molding.

[0016] In the aforementioned male plug power cord holding structure, the outer wall of the metal tube is provided with an annular groove coaxial with the metal tube, and the long strip block forms an annular protrusion matching the annular groove in the annular groove, which plays an axial limiting role, so that the metal tube is more stably embedded in the long strip block.

[0017] Compared with existing technologies, the power cord holding structure of this plug has the following advantages:

[0018] 1. This application uses a strip groove formed on the top of the plug and the strip groove and cable tie to suspend and position the entire plug body. This not only simplifies the structure, but also makes the method more adaptable to various working conditions and more practical.

[0019] 2. Placing long strips on the transition section with a smaller outer diameter can reduce the space occupied by the plug body as a whole. The long strips also act as a reinforcing rib to compensate for the reduction in strength caused by the reduction in the outer diameter of the transition section, thus ensuring the overall strength of the insulating shell.

[0020] 3. By embedding metal tubes inside the long strip to form a round hole, the pressure resistance of the round hole can be improved, so as to hang the plug more stably. It can also make the round hole more wear-resistant and extend the service life of the plug body. Attached Figure Description

Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figure 1 As shown, the power cord holding structure of this plug includes a plug body and a wire 2 electrically connected to the plug body. The connection between the plug body and the wire 2 is existing and will not be described in detail here.

[0027] The plug body includes an L-shaped insulating shell 1, which is generally made of plastic. The insulating shell 1 is an integral structure, consisting of a horizontally arranged electrical connection part 1a and a vertically arranged wire introduction part 1b. Both the electrical connection part 1a and the wire introduction part 1b are elongated, and the wire introduction part 1b is usually integrated with the outer shell of the wire 2.

[0028] in,

[0029] The electrical connection part 1a consists of an insertion section 1a1 and a transition section 1a2, with the rear end of the insertion section 1a1 connected to the wire introduction part 1b via the transition section 1a2. A horizontally formed insertion post 1a3 is formed on the front end surface of the insertion section 1a1; the number of insertion posts 1a3 can be one or more, depending on the actual product. Figure 1 and Figure 2 As shown, a ring-shaped limiting seat 1a4 is formed at the connection between the insertion section 1a1 and the transition section 1a2, and the limiting seat 1a4 and the electrical connection part 1a are coaxially arranged. The outer diameter of the transition section 1a2 is smaller than the outer diameter of the insertion section 1a1. An elongated block 1a5 is integrally formed on the top wall of the transition section 1a2. The elongated block 1a5 has a strip groove 1a6 that extends through the thickness direction of the elongated block 1a5. At this time, the opening direction of the strip groove 1a6 is perpendicular to the length direction of the elongated block 1a5. The length extension directions of the elongated block 1a5, the electrical connection part 1a, and the strip groove 1a6 are consistent. The front end of the elongated block 1a5 extends to the limiting seat 1a4, and both ends of the strip groove 1a6 are closed.

[0030] When in use, insert the insertion section 1a1 of the plug body into the socket of the female plug and press the limiting seat 1a4 against the edge of the socket to electrically connect the plug body and the female plug. Then, pass the cable tie through the strip groove 1a6 and suspend and position the plug body on the frame or other components to prevent the plug body from falling after being pulled out.

[0031] Preferably, an annular positioning groove is formed on the outer wall of the insertion section 1a1, and the positioning groove and the insertion section 1a1 are coaxially arranged. A sealing ring 3 is provided in the positioning groove. When the insertion section 1a1 is inserted into the female plug, the outer wall of the sealing ring 3 contacts the inner wall of the aforementioned socket to form a seal.

[0032] This application uses a strip groove 1a6 formed on the top of the plug body and the strip groove 1a6 and cable tie to suspend and position the entire plug body. This not only simplifies the structure, but also makes the method more adaptable to various working conditions and more practical.

[0033] Meanwhile, placing the long strip 1a5 on the transition section 1a2 with a smaller outer diameter can reduce the space occupied by the plug body as a whole. The long strip 1a5 also acts as a reinforcing rib to compensate for the strength reduction caused by the reduction in the outer diameter of the transition section 1a2, so as to ensure the overall strength of the insulating shell 1.

[0034] To further explain, an inverted U-shaped reinforcing part 1a7 is also formed on the outer wall of the transition section 1a2. The reinforcing part 1a7 is coaxially arranged with the electrical connection part 1a. The reinforcing part 1a7 is located behind the long strip 1a5, and the rear end of the long strip 1a5 extends to the reinforcing part 1a7 to further enhance the strength of the transition section 1a2.

[0035] like Figure 2 and Figure 3 As shown, the elongated block 1a5 also has a circular hole 4a extending through the thickness of the block 1a5. In practical use, the circular hole 4a can be used with a hanging rope to suspend the plug, increasing the number of ways to suspend the plug and improving its practicality. Preferably, the circular hole 4a is located between the strip groove 1a6 and the reinforcing part 1a7, and is positioned close to the reinforcing part 1a7 to ensure the strength of the elongated block 1a5 and to more stably suspend the plug.

[0036] In this embodiment, the circular hole 4a is formed as follows: a metal tube 4 is horizontally embedded inside the elongated block 1a5, and the inner hole of the metal tube 4 is the aforementioned circular hole 4a. By embedding the metal tube 4 inside the elongated block 1a5 to form the circular hole 4a, the compressive strength of the circular hole 4a can be improved, allowing for more stable suspension of the plug, and the circular hole 4a can also be made more wear-resistant, extending the service life of the plug. The metal tube 4 is made of one of the following metal materials: stainless steel, aluminum alloy, etc.

[0037] Preferably, the metal tube 4 and the insulating shell 1 are formed into a whole by injection molding. To further explain, the outer wall of the metal tube 4 is provided with an annular groove coaxial with the metal tube 4, and the elongated block 1a5 forms an annular protrusion 1a8 in the annular groove that matches the annular groove, which plays an axial limiting role, so that the metal tube 4 is more stably embedded in the elongated block 1a5.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
