[0002] With the development trend of miniaturization and thinness of consumer electronic products such as laptops and mobile phones, and the narrow space for the integration of dense electrical components inside vehicles, the design and manufacturing process requirements of their components are becoming higher and higher, which requires that the internal layout of the product must be dense, and the size of each electronic component is getting smaller and smaller, and thinner and lighter. The requirements for process technology and product connection reliability are getting higher and higher, and the demand for multi-functional plug-in products is also increasing. Traditional electrical connectors are usually single-function products, and only one electrical connector can be plugged in at a time. Therefore, the use scenarios are limited, and multiple electrical connectors cannot be equipped at the same time for corresponding plug-in. Once multiple electrical connectors are used, the safety of the entire high-voltage system and various high-voltage electrical equipment, as well as each other, will be affected. Therefore, for this kind of multi-functional application needs, the design scheme of existing electrical connectors is obviously unable to meet them.

[0003] In view of this, the inventor specially designed a bidirectional plug-in electrical connector, and this case was thus generated. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model. Example

[0027] like Figure 1 As shown, an embodiment of the utility model is: a bidirectional plug-in electrical connector, which is formed by bending a metal sheet and closing the two ends of the metal sheet to form a flat body 1 that is penetrated in a single direction. The body 1 is penetrated in a single direction to form a first plug interface 21 and a second plug interface 22. A plug-in space 3 for connecting external electronic components is formed between the first plug interface 21 and the second plug interface 22. The connection work is carried out in the area surrounded by the metal sheet, which plays a role in safe and effective connection. A small section is first extended at one edge of the first plug interface 21 and bent toward the plug space 3 to form a stopper 4 for connecting, guiding and stopping external components. With this arrangement, the external electronic components can be connected quickly and accurately to the second plug interface 22.

[0028] like Figure 2As shown, a convex edge 5 is provided at one end of the metal sheet, and when the ends of the metal sheet are closed to form the main body 1, a portion of the ends of the metal sheet are bent and overlapped, and a bayonet 6 matching the shape of the convex edge 5 is provided in the overlapping area. When the convex edge 5 is tightly closed and bent, the bayonet 6 is just stuck to the bayonet 6, which is convenient for further fixation and prevents the ends of the main body 1 from being separated in a relatively shaking working environment, thereby improving work efficiency and work stability.

[0029] like Figure 3 As shown, the stopper 4 structure includes a first curved portion 41 extending and bent along an edge of the first plug-in port 21, the tail end of the first curved portion 41 extends to form a first straight portion 42, the first straight portion 42 extends and bends toward the first curved portion 41 to form a second curved portion 43, and the second curved portion 43 extends to form a second straight portion 44.

[0030] The entire stopper 4 is biased toward one side. Specifically, the distance between the connection between the first curved portion 41 and the first straight portion 42 and the inner wall of the plug-in space 3 is H, and the distance between the connection between the first straight portion 42 and the second curved portion 43 and the inner wall of the plug-in space 3 is h, and H is greater than h. The distance between the connection between the second curved portion 43 and the second straight portion 44 and the inner wall of the plug-in space 3 is G, and the distance between the free end of the second straight portion 44 and the inner wall of the plug-in space 3 is g, and G is greater than g. At this time, an area that narrows from wide to narrow is formed from the first plug-in interface 21 to the second plug-in interface 22. When inserting along the first plug-in interface 21, the narrow area serves to fix and restrain the external electronic components, and achieves effective and accurate connection contact.

[0031] like Figure 1 and Figure 2 The outer surface of the main body 1 close to the first straight portion 42 is recessed inward and forms a first protrusion 81 toward the first straight portion 42, a second protrusion 82 is provided on the outer surface of the second straight portion 44 toward the first protrusion 81, and a third protrusion 83 is provided on the inner surface of the main body 1 close to the second straight portion 44 toward the second straight portion 44.

[0032] The first protrusion 81 is in the shape of a thin strip. There are two first protrusions 81. When the external electronic component is plugged in, the area enclosed by the two thin strip-shaped first protrusions 81 and the second protrusion 82 forms a limit for the external electronic component and a tighter contact area, making the connection tighter and the contact effect better. Similarly, the third protrusion 83 is set to reduce the insertion distance between the second straight portion 44, and increase the contact stability by increasing the larger surface contact area.

[0033] In order to make the entire body 1 more stably fixed in the use scenario, one edge of the second socket is extended and bent to form a pin 7 for fixing the body 1. The cross-sectional shape of the entire body 1 is also a rectangular parallelepiped, and the regular geometric shape is also convenient for saving space in dense layout, and the appearance is also flatter. Example

[0034] The utility model provides a bidirectional plug-in electrical connector, compared with the first embodiment, see Figure 4-5 The first protrusion 81 is in a rectangular shape. With this arrangement, the first protrusion 81 and the second protrusion 82 further reduce the space of the first plug interface 21, and the rectangular first protrusion 81 provides a larger contact area, so that the entire external electronic component is in closer contact, has better stability, and has a better contact effect.

[0035] In summary, a bidirectional plug-in electrical connector disclosed in an embodiment of the present application forms a flat rectangular main body 1 with two plug-in ports by closing the ends of a metal sheet. The bidirectional plug-in ports facilitate the plug-in of a plurality of electronic components in a narrow space. A stopper 4 is provided in the plug-in space 3 of the main body 1 to facilitate the smooth and effective contact of external electronic components from the first plug-in port 21 to the second plug-in port 22. The first protrusion 81 and the second protrusion 82 make the entire connection more stable, and the entire metal bend is made more stable and not easy to disengage by providing the convex edge 5 and the bayonet 6. The added pin 7 also makes the entire utility model plug-in more stable and convenient for use in different scenarios. The present application has a simple structure and high efficiency, solves the problem of connecting multiple electronic components in a narrow space, and ensures the safety, insulation, and electromagnetic interference shielding of the entire high-voltage system and various high-voltage electrical equipment.

[0036] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
