German type plug sleeve with curved arch shaped force storage and energy concentration structure

Abstract

This invention belongs to the field of German-style plug technology, and more particularly to a German-style plug with a curved, arched energy-gathering structure. It includes a left support and a right support, with an upper and lower arched strip installed between them. An insertion area is formed at the center between the upper and lower arched strips, and energy-gathering areas are formed on both the upper and lower arched strips. The curved, arched energy-gathering area is formed by setting outwardly arched curved structures on the upper and lower arched strips. When the plug is inserted into the insertion area, the plug pushes the upper and lower arched strips outward, causing the arched structure to elastically deform and accumulate energy. When the plug is pulled out, the accumulated elastic potential energy is smoothly released, pushing the arched strips back to their original position.

Description

Technical Field

[0001] This invention belongs to the field of German-style socket technology, specifically relating to a German-style socket with a curved, energy-saving structure. Background Technology

[0002] German-style sockets (also known as DIN standard socket sockets) are core conductive components widely used in power sockets in Europe and many other countries around the world. They are used to form a reliable electrical contact connection with the plug. During the insertion and removal of the plug, the socket needs to have good elastic deformation capacity and stable contact pressure to ensure smooth plug insertion and easy removal, while maintaining sufficient clamping force to prevent the plug from loosening or falling off during use.

[0003] Currently, most German-style plugs on the market adopt traditional straight-arm or bent-arm structures, formed by stamping metal sheets, relying on the elastic deformation of the plug arms to hold the plug. However, this traditional structure has the following shortcomings in practical applications: when the plug is inserted, the deformation direction and amount of the plug arms lack effective resistance and energy storage structures, the insertion and extraction force curve changes non-linearly, and problems such as excessive resistance during insertion and jamming or sudden loosening during extraction are prone to occur, affecting the user experience. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a German-style socket with a curved, energy-concentrating structure, which offers the advantage of smooth plug insertion and removal.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a German-style socket with a curved bow-shaped energy storage and focusing structure, comprising a left support and a right support, wherein an upper bow-shaped strip and a lower bow-shaped strip are jointly installed between the left support and the right support, an insertion area is formed at the center position between the upper bow-shaped strip and the lower bow-shaped strip, and an energy storage and focusing area is formed on both the upper bow-shaped strip and the lower bow-shaped strip.

[0006] As a preferred embodiment of the German-style socket with a curved energy storage and focusing structure of the present invention, both the upper and lower curved bars are outwardly arched curved structures.

[0007] As a preferred embodiment of the German-style socket with a curved energy storage and focusing structure of the present invention, the energy storage and focusing area is located at the apex region of the curved shape of the upper and lower curved bars.

[0008] As a preferred embodiment of the German-style socket with a curved energy storage and focusing structure of the present invention, the curved structure of the upper and lower curved strips is a continuous 3D curved surface design.

[0009] As a preferred embodiment of the German-style socket with a curved energy storage and focusing structure of the present invention, the left and right supports are respectively provided with a solder hook hole one and a solder hook hole two.

[0010] As a preferred embodiment of the German-style socket with a curved energy storage and focusing structure of the present invention, the top of the right-side bracket is also provided with a clearance groove, which is located above the second solder hook hole.

[0011] As a preferred embodiment of the German-style socket with a curved energy storage and concentration structure of the present invention, the left support, right support, upper bow strip and lower bow strip are integrally stamped structures.

[0012] As a preferred embodiment of the German-style socket with a curved energy storage and focusing structure of the present invention, the left support, right support, upper bow-shaped strip and lower bow-shaped strip are all made of copper.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention forms a curved, arched energy storage zone by setting outward-arching curved structures on the upper and lower arched strips. When the plug is inserted into the insertion zone, the plug pushes the upper and lower arched strips to expand outward, causing the arched structure to undergo elastic deformation and accumulate energy; when the plug is pulled out, the accumulated elastic potential energy is smoothly released, pushing the arched strips to return to their original position.

[0015] 2. The present invention uses the bow-shaped bending structure of the upper and lower bow-shaped bars to make the plug insertion and removal smoother and prevent jamming. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figure 1-3 As shown: A German-style socket with a curved bow-shaped energy storage and focusing structure includes a left support 1 and a right support 2. An upper bow-shaped strip 3 and a lower bow-shaped strip 4 are installed between the left support 1 and the right support 2. An insertion area 5 is formed at the center position between the upper bow-shaped strip 3 and the lower bow-shaped strip 4, and an energy storage and focusing area 6 is formed on both the upper bow-shaped strip 3 and the lower bow-shaped strip 4.

[0033] In this embodiment: Specifically, during use, the German-style plug is fixedly installed inside the socket housing via the left bracket 1 and the right bracket 2. When the plug is inserted, it enters the insertion area 5 between the upper bow-shaped bar 3 and the lower bow-shaped bar 4. At this time, the plug pushes the upper bow-shaped bar 3 and the lower bow-shaped bar 4 outward. During the insertion process, the bow-shaped structure undergoes elastic deformation, accumulating elastic potential energy in the energy storage area 6. When the plug is pulled out, the accumulated elastic potential energy is smoothly released, pushing the upper bow-shaped bar 3 and the lower bow-shaped bar 4 back to their original positions, allowing the plug to be smoothly removed.

[0034] In an optional embodiment, both the upper bow-shaped strip 3 and the lower bow-shaped strip 4 are outwardly arched bow-shaped curved structures.

[0035] In this embodiment: Specifically, this outward arching structure is opposite to the deformation direction generated when the plug is inserted. When the plug is inserted, it forces the bow-shaped strip to expand outward, and the bow-shaped strip produces a counter-elastic deformation, thereby accumulating elastic force.

[0036] In an optional embodiment, the energy storage and concentration zone 6 is located at the apex region of the bow-shaped bend of the upper bow-shaped bar 3 and the lower bow-shaped bar 4.

[0037] In this embodiment: Specifically, this area bears the greatest bending stress and accumulates the most elastic potential energy when the plug is inserted; when the plug is pulled out, the energy storage area 6 releases the elastic potential energy, driving the bow-shaped strip to return to its original shape.

[0038] In an optional embodiment, the bow-shaped structures of the upper bow-shaped strip 3 and the lower bow-shaped strip 4 are a continuous 3D curved surface design.

[0039] In this embodiment: Specifically, the above design ensures that the plug is inserted and removed more smoothly, avoiding jamming problems.

[0040] In an optional embodiment, solder hook hole 11 and solder hook hole 22 are respectively provided on the left bracket 1 and the right bracket 2.

[0041] In this embodiment: Specifically, the solder hook hole 11 and the solder hook hole 22 are provided to achieve electrical connection.

[0042] In an optional embodiment, a clearance groove 21 is also provided on the top of the right bracket 2, and the clearance groove 21 is located above the solder hook hole 22.

[0043] In this embodiment: Specifically, by setting the clearance groove 21, it is ensured that there will be no structural interference when the right bracket 2 is installed.

[0044] In one optional embodiment, the left support 1, the right support 2, the upper bow-shaped strip 3, and the lower bow-shaped strip 4 are integrally stamped structures.

[0045] In this embodiment: Specifically, the one-piece stamping process ensures the relative positional accuracy between the components and the overall structural strength, avoiding the loosening problem that may occur in a split structure.

[0046] In an optional embodiment, the left support 1, the right support 2, the upper bow-shaped strip 3, and the lower bow-shaped strip 4 are all made of copper.

[0047] In this embodiment: Specifically, metallic copper has excellent electrical conductivity and elasticity, which can ensure electrical conductivity while ensuring that the upper bow-shaped strip 3 and the lower bow-shaped strip 4 return to their original position after deformation.

[0048] Example 2

[0049] Please see Figure 4 , Figure 5 and Figure 6 An improvement is made to the German-style socket with a curved energy storage and focusing structure in Embodiment 1:

[0050] Connect the two German-style sockets from Embodiment 1 end to end to form a two-position German-style socket structure.

[0051] Example 3

[0052] Please see Figure 7 , Figure 8 and Figure 9 An improvement is made to the German-style socket with a curved energy storage and focusing structure in Embodiment 1:

[0053] Connect the three German-style sockets from Embodiment 1 end to end to form a three-position German-style socket structure.

[0054] Example 4

[0055] Please see Figure 10 , Figure 11 and Figure 12 An improvement is made to the German-style socket with a curved energy storage and focusing structure in Embodiment 1:

[0056] The insertion area 5 of the German-style socket in Example 1 is changed to a rhombus shape. This improvement doubles the contact area compared to the semi-circular socket, significantly improving the current carrying capacity and reducing the temperature rise.
