[0022] Based on the above technical solutions, the technical effects that the present utility model can achieve are analyzed as follows:
[0023] The socket with a limited position frame for L pole and N pole provided by the utility model comprises a first contact spring, a second contact spring and a fixed base; the first contact spring and the second contact spring both comprise a base connecting wall, two elastic walls, two upright arc surfaces and two bent connecting walls, the two ends of the base connecting wall are respectively vertically connected with the two elastic walls to form a receiving area, the two upright arc surfaces are arranged oppositely and are both located in the receiving area, and the two upright arc surfaces are respectively connected with the two elastic walls through the two bent connecting walls; the fixed base is provided with a first limiting frame and a second limiting frame, the first contact spring The sheet is installed in the first limit frame, and the end of the elastic wall of the first contact spring sheet away from the bent connecting wall abuts against the first limit frame, the base connecting wall abuts against the first limit frame, and a first deformation avoidance zone is formed between the two bent connecting walls of the first contact spring sheet and the first limit frame; the second contact spring sheet is installed in the second limit frame, and the end of the elastic wall of the second contact spring sheet away from the bent connecting wall abuts against the second limit frame, the base connecting wall abuts against the second limit frame, and a second deformation avoidance zone is formed between the two bent connecting walls of the second contact spring sheet and the second limit frame.
[0024] The first contact spring sheet and the second contact spring sheet are L / N spring sheets respectively; the two opposite upright arc surfaces are used to contact the plug PIN column; the base connecting wall is used to connect the two elastic walls; and the two bent connecting walls are used to connect the upright arc surfaces and the elastic walls.
[0025] The first limit frame is used to install the first contact spring, which is used to limit the movement of the first contact spring in the X and Y directions; the first deformation avoidance zone is formed between the two bent connecting walls and the first limit frame. When the plug PIN column is inserted into the first contact spring, the two relatively set upright arc surfaces are stretched outward by force and synchronously transmitted to the elastic wall, and the elastic wall produces elastic deformation; the two first deformation avoidance zones can accommodate the elastic deformation of the elastic wall, and will not produce blocking counterforce and harmful plastic deformation to the elastic wall. When the plug PIN column is pulled out, the elastic wall generates a rebound force due to its own elastic properties, returns to the initial position, and maintains the original shape. During the reciprocating process, the elastic wall can always meet its appropriate elastic properties and achieve the initial compatibility design requirements.
[0026] Similarly, the second limiting frame is used to install the second contact elastic piece and limit the movement of the second contact elastic piece in the X and Y directions; a second deformation avoidance area is formed between the two bending connection walls and the second limiting frame. When the plug PIN post is inserted into the second contact elastic piece, the two oppositely arranged upright arc surfaces are forced to expand outward, which is synchronously conducted to the elastic wall, and the elastic wall undergoes elastic deformation; the two second deformation avoidance areas can accommodate the elastic deformation amount of the elastic wall, without generating blocking counterforce and causing harmful plastic deformation to the elastic wall. When the plug PIN post is pulled out, the elastic wall generates a return elastic force due to its own elastic property and returns to the initial position, maintaining its original shape. During the reciprocating process, the elastic wall can always meet its appropriate elastic property and achieve the initial compatibility design requirements.
[0027] In this way, the structural stability of the elastic deformation of the first contact elastic piece and the second contact elastic piece can be enhanced, well adapting to the compatibility design requirements of different specifications of gauges and improving reliability.

[0048] There is a need for a specification compatibility design for 10A and 16A European standard sockets in the market, which is specifically reflected in the compatibility requirements of the contact spring structure, that is, to meet the diameter size difference of the inspection gauge, and the minimum standard diameter gauge clamping force test is qualified as the standard. The currently common form of the spring structure often causes problems of failed certification on products with compatibility requirements, and there are also problems with poor reliability of live contact. In view of this, the embodiments of the present utility model optimize the spring structure, reduce the risk of safety certification failure, especially to be compatible with the hanging weight evaluation of gauges of different specification sizes, and improve the reliability of live contact of socket products.
[0049] Please refer to Figures 1 to 8The socket with L-pole and N-pole limit frames provided by the embodiment of the utility model comprises a first contact spring 100, a second contact spring 200 and a fixed base 300; the first contact spring 100 and the second contact spring 200 both comprise a base connecting wall 110, two elastic walls 120, two upright arc surfaces 130 and two bent connecting walls 140, the two ends of the base connecting wall 110 are respectively vertically connected to the two elastic walls 120 to form a receiving area 150, the two upright arc surfaces 130 are oppositely arranged and are both located in the receiving area 150, and the two upright arc surfaces 130 are respectively connected to the two elastic walls 120 through the two bent connecting walls 140; the fixed base 300 is provided with a first limit frame 310 and a second limit frame 320, the first contact spring 100 It is installed in the first limit frame 310, and the end of the elastic wall 120 of the first contact spring 100 that is away from the bent connecting wall 140 abuts against the first limit frame 310, the base connecting wall 110 abuts against the first limit frame 310, and a first deformation avoidance zone 315 is formed between the two bent connecting walls 140 of the first contact spring 100 and the first limit frame 310; the second contact spring 200 is installed in the second limit frame 320, and the end of the elastic wall 120 of the second contact spring 200 that is away from the bent connecting wall 140 abuts against the second limit frame 320, the base connecting wall 110 abuts against the second limit frame 320, and a second deformation avoidance zone 316 is formed between the two bent connecting walls 140 of the second contact spring 200 and the second limit frame 320.
[0050] Specifically, the first limiting frame 310 and the second limiting frame 320 can be configured as a fully enclosed frame structure or a semi-enclosed frame structure. The cross sections of the two upright arc surfaces 130 of the first contact spring 100 and the second contact spring 200 are both configured as arcs and are concave in directions away from each other.
[0051] The first contact elastic piece 100 and the second contact elastic piece 200 are respectively L / N elastic pieces; two opposite upright arc surfaces 130 are used for contacting the plug PIN post. The base connection wall 110 is used for connecting the two elastic walls 120, and the two bent connection walls 140 are used for connecting the upright arc surface 130 and the elastic wall 120. The first limiting frame 310 is used for installing the first contact elastic piece 100 to limit the movement of the first contact elastic piece 100 in the X direction and the Y direction; a first deformation avoidance area 315 is formed between the two bent connection walls 140 and the first limiting frame 310. When the plug PIN post is inserted into the first contact elastic piece 100, the two oppositely arranged upright arc surfaces 130 are forced to expand outwards, and are synchronously conducted to the elastic wall 120, and the elastic wall 120 generates elastic deformation; the two first deformation avoidance areas 315 can accommodate the elastic deformation amount of the elastic wall 120, and no blocking counter-force will be generated to cause harmful plastic deformation to the elastic wall 120.

During the reciprocating process, the elastic wall 120 can always meet its appropriate elastic property to achieve the initial compatibility design requirements.

When the plug PIN post is inserted into the second contact elastic piece 200, the two oppositely arranged upright arc surfaces 130 are forced to expand outwards, and are synchronously conducted to the elastic wall 120, and the elastic wall 120 generates elastic deformation; the two second deformation avoidance areas 316 can accommodate the elastic deformation amount of the elastic wall 120, and no blocking counter-force will be generated to cause harmful plastic deformation to the elastic wall 120. When the plug PIN post is pulled out, the elastic wall 120 generates a return force due to its own elastic property and returns to the initial position, maintaining its original shape. During the reciprocating process, the elastic wall 120 can always meet its appropriate elastic property to achieve the initial compatibility design requirements. In this way, the structural stability of the elastic deformation of the first contact elastic piece 100 and the second contact elastic piece 200 can be enhanced, well adapting to the compatibility design requirements of different specifications of gauges, and improving the reliability.
[0052] The shape and structure of the socket with limiting frames for the L pole and the N pole are described in detail below:
[0053] In the optional solution provided by the embodiment of the present invention, referring to Figure 3 , the cross-sections of the bent connection walls 140 of the first contact elastic piece 100 and the second contact elastic piece 200 are both set to be arc-shaped; or, referring to Figure 7 , the cross-sections of the bent connection walls 140 of the first contact elastic piece 100 and the second contact elastic piece 200 are both set to be square.
[0054] Specifically, in this embodiment, the shapes and sizes of the first contact elastic piece 100 and the second contact elastic piece 200 are the same; of course, the shapes and sizes of the first contact elastic piece 100 and the second contact elastic piece 200 are different, but the structures that can be adapted to the same plug, for example, the cross-section of the bent connection wall 140 of the first contact elastic piece 100 is set to be arc-shaped, while the cross-section of the bent connection wall 140 of the second contact elastic piece 200 is set to be square, should also be within the protection scope of the embodiments of the present invention.
[0055] The bent connection wall 140 realizes the connection between the elastic wall 120 and the upright arc surface 130.
[0056] In the alternative solution provided by the embodiment of the present invention, referring to Figure 1 and Figure 2 , when the cross-sections of the bent connection walls 140 of the first contact elastic piece 100 and the second contact elastic piece 200 are both set to be arc-shaped, one end of the elastic wall 120 of the first contact elastic piece 100 departing from the bent connection wall 140 abuts against the inner wall of the first limiting frame 310, and one end of the elastic wall 120 of the second contact elastic piece 200 departing from the bent connection wall 140 abuts against the inner wall of the second limiting frame 320.
[0057] Specifically, referring to Figure 3 , an arc transition is formed between the bent connection wall 140, the elastic wall 120 and the upright arc surface 130.
[0058] The bent connection wall 140 of the first contact elastic piece 100 is set to be arc-shaped, increasing the distance between the outer wall of the bent connection wall 140 and the inner wall of the first limiting frame 310, so as to form a first deformation avoidance area 315, realizing that the first deformation avoidance area 315 provides space for the deformation of the elastic wall 120; and, the elastic wall 120 directly abuts against the first limiting frame 310 to realize the installation of the first contact elastic piece 100. Similarly, the bent connection wall 140 of the second contact elastic piece 200 is set to be arc-shaped, increasing the distance between the outer wall of the bent connection wall 140 and the inner wall of the second limiting frame 320, so as to form a second deformation avoidance area 316, realizing that the second deformation avoidance area 316 provides space for the deformation of the elastic wall 120; and, the elastic wall 120 directly abuts against the second limiting frame 320 to realize the installation of the second contact elastic piece 200.

[0060] Specifically, since the limiting rib 312 protrudes from the inner wall of the first limiting frame 310 or the second limiting frame 320, a gap is formed between the outer wall of the bending connection wall 140 and the inner wall of the first limiting frame 310 or the second limiting frame 320 to form a deformation avoidance area. Therefore, when the installation method of the limiting rib 312 is adopted, the cross section of the bending connection wall 140 can be set to be arc-shaped or square.
[0061] The inner wall of the first limiting frame 310 is provided with a limiting rib 312, and the elastic wall 120 of the first contact elastic piece 100 is clamped with the limiting rib 312, so as to install the first contact elastic piece 100 in the first limiting frame 310.

[0063] The limiting rib 312 is attached to the inner wall of the first limiting frame 310 or the second limiting frame 320, increasing the contact area between the limiting rib 312 and the first contact elastic piece 100 or the second contact elastic piece 200, and enhancing the limiting effect.
[0064] In an alternative solution provided by the embodiment of the present invention, a first step 313 is provided at the bottom of the limiting rib 312, and the elastic wall 120 is located on the first step 313.
[0065] Specifically, referring to Figure 8 , the limiting rib 312 and the first step 313 are integrally formed.
[0066] The elastic wall 120 is lapped on the first step 313.
[0067] In an alternative solution provided by the embodiment of the present invention, two second steps 314 are provided on the inner walls of both the first limiting frame 310 and the second limiting frame 320, the two second steps 314 are arranged oppositely, and one end of the elastic wall 120 close to the upright arc surface 130 is located on the second step 314.
[0068] Specifically, the heights of the first step 313 and the second step 314 are the same, so that the elastic wall 120 is in a horizontal state. The width of the second step 314 is greater than the width of the first step 313.
[0069] The second step 314 supports the elastic wall 120, so that the elastic wall 120 is in a horizontal state.

Preferably, an arc transition connection is adopted between the bent connecting wall 140, the elastic wall 120 and the upright arc surface 130.
[0072] The reinforcing ribs 160 are used to strengthen the strength of the bent connecting wall 140 and extend the service life of the first contact elastic piece 100 and the second contact elastic piece 200.
[0073] In an alternative solution provided by an embodiment of the present utility model, the first contact elastic piece 100 and the second contact elastic piece 200 are arranged opposite to each other.
[0074] Specifically, the first contact elastic piece 100 and the second contact elastic piece 200 are arranged opposite to each other. Correspondingly, the first limiting frame 310 and the second limiting frame 320 are arranged opposite to each other.
[0075] The first contact elastic piece 100 and the second contact elastic piece 200 are arranged opposite to each other to adapt to the structure of the plug PIN post.

[0077] Specifically, the first notch 311 of the first limiting frame 310 is arranged on the upper side of the first limiting frame 310, and the second notch 321 of the second limiting frame 320 is arranged on the lower side of the second limiting frame 320. The first notch 311 is used to avoid the square block connected to the elastic wall 120 of the first contact elastic piece 100, and the second notch 321 is used to avoid the square block connected to the elastic wall 120 of the second contact elastic piece 200.
[0078] The first notch 311 and the second notch 321 realize the avoidance of the first contact elastic piece 100 and the second contact elastic piece 200.
