DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] In the description of the present invention, it should be understood that some directional terms are based on the directions or positional relationships shown in the drawings, and are only used to facilitate the description of the present invention and simplify the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In the embodiments of the present invention, such as "upper", "lower", "side", etc., generally, the terms "upper", "lower", "side", etc. are used as the reference numerals. Figure 1 The relative relationship of the orientation shown in the figure is used as the basis, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientation. When the product is placed in different postures, the orientation may change, for example, "up" and "down" may be interchangeable.

[0042] In order to make the technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] Figure 1 A cross-sectional view of a plug pin provided in an embodiment of the utility model, Figure 1 In the order from top to bottom, the first structural diagram is a schematic diagram of the overall structure of the pin, the second structural diagram is a cross-sectional diagram of the first structural diagram along the AA line, and the third structural diagram is an exploded diagram of the second structural diagram. Figure 1 The plug provided in the embodiment of the utility model includes a body 1 and a reinforcement 2.

[0044] The body 1 is hollow inside and has an open end 11 . A limiting boss 12 is provided on one side of the body 1 close to the open end 11 . A protrusion 13 extending toward the inside of the body 1 is provided at the port of the open end 11 .

[0045] The reinforcement member 2 is located in the body 1 , one end of the reinforcement member 2 abuts against the limiting boss 12 , the other end of the reinforcement member 2 has a recessed portion 21 , and the raised portion 13 is located in the recessed portion 21 .

[0046] Therefore, the plug pin provided by the embodiment of the utility model is provided with a limiting boss 12 on one side of the inner part of the body 1 close to the open end 11, so that one end of the reinforcement member 2 can abut against the limiting boss 12; and a protrusion 13 extending toward the inner part of the body 1 is provided at the port of the open end 11 of the body 1, so that the recessed part 21 at the other end of the reinforcement member 2 cooperates with the protrusion 13, so that the reinforcement member 2 can be firmly fixed in the body 1 to avoid being separated from the body 1 during use or testing. At the same time, by providing the protrusion 13 to cooperate with the recessed part 21, the contact area between the body 1 and the reinforcement member 2 can be increased, so that the conductivity is better and the temperature rise of the plug pin is slower.

[0047] In addition, since the interior of the main body 1 is hollow, that is, the main body 1 is a hollow structure, compared with the solid pins used in existing electrical equipment (such as sockets or plugs), the pins provided in the embodiment of the utility model can save materials, reduce costs, and are more conducive to environmental protection.

[0048] The structure of the plug provided by the embodiment of the utility model is described in detail below:

[0049] In some embodiments, see Figure 2 The main body 1 includes a fixed portion 101 and an extending portion 102 which are connected to each other.

[0050] The cross-sectional area of ​​the hollow portion of the fixing portion 101 is greater than the cross-sectional area of ​​the hollow portion of the extending portion 102 , and the limiting boss 12 is formed at the connection between the fixing portion 101 and the extending portion 102 .

[0051] Continue to see Figure 2 The open end 11 is located on a side of the fixing portion 101 away from the extending portion 102 .

[0052] In some embodiments, see Figure 1 The limiting boss 12 is annular so as to abut against one end of the reinforcing member 2.

[0053] In some embodiments, see Figure 1 The central axis of the fixing portion 101 is colinear with the central axis of the extending portion 102 to facilitate processing and preparation to form the limiting boss 12 .

[0054] In some embodiments, see Figure 3 The extending direction of the protrusion 13 is perpendicular to the central axis of the fixing portion 101 or the central axis of the extending portion 102 .

[0055] In some embodiments, see Figure 1 The raised portion 13 and the recessed portion 21 are both annular, so that the main body 1 forms a seamless edge structure, ensuring that the reinforcement member 2 is firmly fixed in the main body 1.

[0056] In some embodiments, see Figure 2 The body 1 also has a closed end 14, and the open end 11 and the closed end 14 are arranged opposite to each other.

[0057] By providing the closed end 14, it is ensured that the body 1 has sufficient strength to prevent the pin from being crushed during the test process.

[0058] Continue to see Figure 2 The closed end 14 is located at an end of the extending portion 102 away from the fixing portion 101 .

[0059] In some embodiments, see Figure 2 and Figure 3The end surface of the open end 11 is a plane to facilitate the fixing of the pin to the base; the end surface of the closed end 14 is an arc surface to enhance the strength of the body 1.

[0060] In some embodiments, see Figure 1 , the closed end 14 is a seamless closed structure. In addition, the closed end 14 can also be a seam closed structure, which is not specifically limited in the embodiment of the utility model.

[0061] In some embodiments, see Figure 1 and Figure 2 The side wall of the main body 1 corresponding to the position where the reinforcement member 2 is installed is in the shape of a flat plate, and the reinforcement member 2 is provided with a corresponding plane.

[0062] Such a configuration not only achieves the fixation of the relative position of the reinforcement member 2 to prevent the reinforcement member 2 from rotating, but also achieves the fixation of the plug pin to prevent the plug pin from rotating after being installed on the base. In addition, by providing a flat side wall on the body 1, foolproof insertion of the reinforcement member 2 can be achieved.

[0063] In some embodiments, the body 1 has two symmetrically arranged flat side walls, and the reinforcement 2 has two corresponding planes symmetrically arranged. Figure 2 and Figure 4 The main body 1 has a first side wall 15 and a second side wall 16 in the form of a flat plate, and the reinforcement 2 has a first plane 201 and a second plane 202 arranged opposite to each other, wherein the first plane 201 is suitable for fitting with the first side wall 15, and the second plane 202 is suitable for fitting with the second side wall 16.

[0064] In some embodiments, the body 1 is made of metal. For example, the body 1 is made of copper.

[0065] In some embodiments, the reinforcement member 2 is made of metal. For example, the reinforcement member 2 is made of copper.

[0066] Based on the above structure, in some embodiments, see Figure 5 , Figure 6 and Figure 7 The plug pin provided in the embodiment of the utility model also includes a bolt 3.

[0067] The body 1 has a first threaded hole 17, and the reinforcement 2 has a second threaded hole 22. The first threaded hole 17 is opposite to and connected to the second threaded hole 22. The reinforcement 2 is hollow inside, and the second threaded hole 22 is connected to the inside of the reinforcement 2. In other words, the first threaded hole 17, the second threaded hole 22 and the inside of the reinforcement 2 are connected to each other.

[0068] One end of the bolt 3 passes through the first threaded hole 17 and the second threaded hole 22 and is located inside the reinforcement 2. Since the bolt 3 has an external thread, and the first threaded hole 17 and the second threaded hole 22 both have an internal thread, when the bolt 3 passes through the first threaded hole 17 and the second threaded hole 22, the external thread can cooperate with the internal thread to achieve a threaded connection between the bolt 3 and the body 1 and the reinforcement 2.

[0069] It can be understood that when the bolt 3 extends into the interior of the reinforcement member 2, the bolt 3 is used to compress the power line (not shown in the figure) to achieve current transmission.

[0070] In a possible example, the pin of the embodiment of the utility model can be prepared according to the following steps:

[0071] Through multiple stamping die processes, a hollow cylindrical structure is obtained;

[0072] By performing composite mold technology on the hollow cylindrical structure, the following Figure 2 Body 1 shown;

[0073] By seamlessly fitting the hemming process, the reinforcement member 2 is assembled into the interior of the body 1 to obtain the following Figure 1 The pin structure shown;

[0074] Screw the bolt 3 into the first threaded hole 17 and the second threaded hole 22 to obtain Figure 6 The pin structure shown.

[0075] The embodiment of the utility model also provides an electrical device, which includes at least one plug pin as described in the above embodiment.

[0076] By adopting this pin, the safe use of electrical equipment is ensured.

[0077] In some embodiments, the electrical device is a socket or a plug.

[0078] In some embodiments, see Figure 8 The electrical device also includes a base 4, and the pin is fixed on the base 4.

[0079] For example, see Figure 8 , the two pins are arranged in parallel on the base 4.
