The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

When an element or layer is referred to as being "on," "engaged to," "connected to" or "coupled to" another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being "directly on," "directly engaged to," "directly connected to" or "directly coupled to" another element or layer, there may be no intervening elements or layers present.

Fig. 4 is a schematic view of an application scenario of the first embodiment of the present invention. As shown in fig. 4, the connection terminal is electrically connected to the PIN 40. The first dome electrode 20 and the second dome electrode 30 clamp the PIN 40. The minimum distance between the first spring plate electrode 20 and the second spring plate electrode 30 is smaller than the outer diameter of the PIN needle. When the PIN is inserted between the first elastic sheet electrode 20 and the second elastic sheet electrode 30, the first elastic sheet electrode 20 is deformed outwards and moves towards the direction close to the first inner wall 111, so that the first contact end 22 is in contact with the first inner wall 111, and the first contact end 22 is subjected to the reaction force of the first inner wall 111; the second elastic sheet electrode 30 is deformed outwards and moves towards the direction close to the second inner wall 112, so that the second contact end 32 is in contact with the second inner wall 112, the second contact end 32 is subjected to the reaction force of the second inner wall 112, and therefore the first elastic sheet electrode 20 and the second elastic sheet electrode 30 have inward acting force, and the PIN needle can be stably clamped.

Since the PIN is first contacted with the first and second bump ends 212 and 312 during the insertion of the PIN into the first and

second dome electrodes

20 and 30. The distance between the first raised end 212 and the second raised end 312 is slightly less than the diameter of the PIN. Like this, when the PIN needle is in between first protruding end 212 and second protruding end 312, receive less clamping-force, because when first protruding end 212 and second protruding end 312, the distance that the PIN needle need continue inwards to insert is longer, and less clamping-force can avoid causing PIN needle damage at the plug in-process to prolong PIN needle's life. The distance between the first and second raised ends 211, 311 is less than the first and second raised ends 212, 312. Because the distance that the PIN needs to be inserted further inward is short when the PIN reaches the position between the first protruding end 211 and the second protruding end 311, the distance between the first protruding end 211 and the second protruding end 311 is small, so that the PIN is subjected to a large clamping force, and the contact between the PIN and the first protruding end 211 and the second protruding end 311 is stable. And when the PIN is located between the first protruding end 211 and the second protruding end 311, the first elastic sheet electrode and the second elastic sheet electrode are greatly deformed, so that the reaction force of the first contact end 22 on the first inner wall 111 is larger, and the reaction force of the second contact end 32 on the second inner wall 112 is larger. This may result in an increased clamping force of the first and second raised ends 212, 312.

The embodiment of the utility model provides an in, through set up two at least first protruding ends on first shell fragment electrode, set up two at least second protruding ends on second shell fragment electrode, centre gripping PIN needle that can be stable avoids PIN needle to insert simultaneously and pulls out the in-process by the damage, prolongs the life of PIN needle.

The minimum distance between the first dome electrode 20 and the second dome electrode 30 is smaller than the thickness dimension of the printed circuit board 50. When the printed circuit board 50 is inserted between the first elastic sheet electrode 20 and the second elastic sheet electrode 30, the first elastic sheet electrode 20 is deformed outward and moves toward the direction close to the first inner wall 111, so that the first contact end 22 is in contact with the first inner wall 111, and the first contact end 22 is subjected to the reaction force of the first inner wall 111; the second elastic sheet electrode 30 is deformed outward and moves in a direction close to the second inner wall 112, so that the second contact end 32 contacts the second inner wall 112, and the second contact end 32 is subjected to a reaction force of the second inner wall 112, so that the first elastic sheet electrode 20 and the second elastic sheet electrode 30 have an inward acting force, and the printed circuit board 50 can be stably clamped.

The embodiment of the utility model provides an in, through set up two at least first protruding ends on first shell fragment electrode, set up two at least second protruding ends on second shell fragment electrode, centre gripping printed circuit board that can be stable avoids printed circuit board plug in-process to be damaged simultaneously, prolongs printed circuit board's life.
