An end of each of the first contact pressing strips 222 away from the first straight plate 21 is bent towards one side of the second elastic sheet 3 to form a first turning plate 223, and the bending angles of each of the first turning plates 223 are the same.
[0030] Each of the first contact pressing strips 222 is arranged to be inclined towards the bottom plate 1, an end point of the first turning plate 223 farthest from the bottom plate 1 is located at the same horizontal plane as the first straight plate 21 on a side of the first elastic sheet 2 away from the bottom plate 1, and an end point of the first contact pressing strip 222 away from the first straight plate 21 is located at a distance from the horizontal plane where the first straight plate 21 is located on a side of the first elastic sheet 2 close to the bottom plate 1, and the distance is half the width of the bottom plate 1, so that when the first straight plate 21 is installed on the bottom plate 1, the first elastic sheets 2 on both sides of the bottom plate 1 can abut each other at the boundary position of the first turning plate 223 and the first contact pressing strip 222. A gap 224 is formed between adjacent two first turning plates 223.
[0031] The second elastic sheet 3 is divided into a second straight plate 31 connected with the first elastic sheet 2 and a second contact plate 32 in contact with the plug sheet, the second straight plate 31 and the second contact plate 32 are integrally formed, the second straight plate 31 and the second contact plate 32 are bent at a position of a boundary therebetween to form a second arc plate segment 321 protruding towards the third elastic sheet 4, the second arc plate segment 321 has the same arc as the first arc plate segment 221, five second contact pressing strips 322 are integrally formed on the second contact plate 32, and gaps with the same interval are formed between each of the second contact pressing strips 322, and each of the second contact pressing strips 322 is arranged opposite to the gap formed between adjacent two first contact pressing strips 222.
[0032] The second contact pressing strip 322 is bent to have a third arc-shaped plate segment 323 protruding towards the third elastic sheet 4. The third arc-shaped plate segment 323 is located on the side of the second elastic sheet 3 close to the third elastic sheet 4. The highest point of the protruding position of the third arc-shaped plate segment 323 is at the same distance from the third elastic sheet 4 as the highest point of the protruding position of the second arc-shaped plate segment 321. The side of the third arc-shaped plate segment 323 away from the second straight plate 31 is connected to a fourth arc-shaped plate segment 324 protruding towards the first elastic sheet 2. The fourth arc-shaped plate segment 324 has the same curvature as the third arc-shaped plate segment 323. The end of the fourth arc-shaped plate segment 324 away from the third arc-shaped plate segment 323 is bent to a second turning plate 325 towards the third elastic sheet 4. The second turning plate 325 is located on the side of the second elastic sheet 3 away from the first elastic sheet 2. The farthest end of the second turning plate 325 away from the first elastic sheet 2 is on the same horizontal plane as the second straight plate 31. The side edges of the second elastic sheet 3 are bent to have turning edges 326 towards the third elastic sheet 4. The turning edges 326 are located on both sides of the second contact plate 32.
[0033] The third elastic sheet 4 is divided into a third straight plate 41 connected to the second elastic sheet 3 and a pressing plate 42 limiting the second contact plate 32 and the first contact plate 22. The third straight plate 41 and the pressing plate 42 are integrally formed. The boundary between the third straight plate 41 and the pressing plate 42 is bent to have a fifth arc-shaped plate segment 421 with the same curvature as the second arc-shaped plate segment 321. The side of the pressing plate 42 close to the second elastic sheet 3 is on the same horizontal plane as the side of the third straight plate 41 away from the second elastic sheet 3. The pressing plate 42 is integrally formed with five main pressing plates 422 and one auxiliary pressing plate 425. There is a distance between each adjacent main pressing plate 422 and between the auxiliary pressing plate 425 and the adjacent main pressing plate 422. Each main pressing plate 422 is provided with a pressing straight plate 423 and a pressing bent plate 424. There is a distance between the pressing straight plate 423 and the pressing bent plate 424. The pressing bent plate 424 is bent towards the second elastic sheet 3. The end of the pressing bent plate 424 away from the third straight plate 41 is bent to a third turning plate 426 away from the second elastic sheet 3. The farthest end of the third turning plate 426 away from the second elastic sheet 3 is on the same horizontal plane as the side of the third straight plate 41 close to the second elastic sheet 3.
[0034] Referring to Figure 3 and Figure 4When the first elastic sheet 2 is connected to the bottom plate 1 and the second elastic sheet 3 is connected to the first elastic sheet 2, the second contact pressing strip 322 is arranged at the interval position between two adjacent first contact pressing strips 222, and the fourth arc-shaped plate segment 324 on the second contact pressing strip 322 extends into the gap 224. When the third elastic sheet 4 is connected to the second elastic sheet 3, the third elastic sheet 4 can be quickly positioned and installed on the second elastic sheet 3 by the quick positioning of the flange 326, and the pressing straight plate 423 on the pressing main plate 422 abuts against the third arc-shaped plate segment 323 on the second contact pressing strip 322, and the pressing curved plate 424 on the pressing main plate 422 is parked behind the first contact pressing strip 222.
[0035] When the plug is inserted into the socket, the plug pin abuts against the first flange 223, because the first flange 223 is bent away from the two sides of the bottom plate 1, and when the plug is pressed towards the bottom plate 1, the plug pin pushes the first flange 223 to the two sides of the bottom plate 1, and the first flange 223 drives the first contact pressing strip 222 to tilt to the two sides of the bottom plate 1, thereby facilitating the quick insertion of the plug pin between the first elastic sheets 2 on the two sides of the bottom plate 1. The gap between two adjacent first contact pressing strips 222 allows each first contact pressing strip 222 to be independently arranged and tilted from the two sides of the first elastic sheet 2 when the plug pin is inserted, so that the plug pin on the plug can be pushed away from the first contact pressing strip 222 by a smaller force, and the plug can be easily inserted into the socket by the staff. After the plug pin is completely inserted, the six first contact pressing strips 222 simultaneously contact and clamp the plug pin, which can ensure sufficient clamping force on the plug pin.
[0036] When the plug pin is inserted between the first elastic sheets 2, the first contact pressing strip 222 on the first elastic sheet 2 tilts towards the second elastic sheet 3 and the third elastic sheet 4, and the fourth arc-shaped plate segment 324 on the second contact pressing strip 322 abuts against the plug pin of the socket through the gap 224, which increases the contact area with the plug pin and further enhances the clamping force on the plug pin by the second contact pressing strip 322 to prevent the plug from falling off the socket. The abutment of the pressing straight plate 423 against the third arc-shaped plate segment 323 can support and limit the second contact pressing strip 322 to prevent it from tilting too much to the two sides of the bottom plate 1, which is beneficial to prolong the service life of the second elastic sheet 3. At the same time, the first flange 223 on the first contact pressing strip 222 abuts against the pressing curved plate 424, which supports the first contact pressing strip 222 to prevent it from tilting too much and protects the first contact pressing strip 222 to prolong its service life.
[0037] The implementation principle of the embodiment of the application is that when the plug is inserted on the socket, the contact piece on the plug pushes the first elastic sheet 2 to tilt to both sides, the first contact pressing strip 222 on the first elastic sheet 2 clamps the contact piece, when the first contact pressing strip 222 tilts to both sides, the second contact pressing strip 322 on the second elastic sheet 3 is in contact with the contact piece to increase the contact area, the first contact pressing strip 222 is in abutment with the pressing bent plate 424 on the pressing main plate 422 to protect the first contact pressing strip 222, and the second contact pressing strip 322 is in abutment with the pressing straight plate 423 on the pressing main plate 422 to protect the second contact pressing strip 322, which is beneficial to improve the use performance and service life of the socket contact terminal.
[0038] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
