The number of the abutting portions 54 may be one, or may be more than one.
Further, as shown in fig. 6, in embodiment 1, the first card 53 is disposed on one side of the buckle body 521 and extends obliquely, and when the buckle 52 is not inserted into the mounting hole 41, the distance L1 between the first free end and the other side of the buckle body 521 is greater than the width D of the mounting hole 41;
when the card holder is installed in the installation hole 41, the card holder 53 is guided by the inclined arrangement of the first card 53, and gradually extends into the installation hole 41, and the abutting portion 54, i.e. the first free end of the first card 53 deforms toward the direction of the buckle body 521 under the abutting action of the end edge of the installation hole 41, so that when the first card 53 is placed in the installation hole 41, the abutting portion 54 of the first card 53 is abutted by the inner wall of the installation hole 42 and is mutually extruded with the inner wall 42 of the installation hole, and the electrical connection between the abutting portion 54 and the inner wall 42 of the installation hole is kept stable.
The distance H2 between the abutting portion 54 and the fixing portion 51 is smaller than the depth T of the mounting hole 41, and H2< T, so that the abutting portion 54 does not penetrate through the mounting hole 41 during mounting, and good electrical contact between the abutting portion 54 and the inner wall 42 of the mounting hole is ensured. The distance D between one side and the other side of the clip body 521 is smaller than the width D of the mounting hole 41. It is ensured that the clip 52 can pass through the mounting hole 41, and the distance between one side and the other side of the clip body 521 is the thickness of the clip body 521.
Make through reasonable structural arrangement: d < L1, it is ensured that the clip 52 can be inserted into the mounting hole 41, and at the same time, the abutting portion 54 and the inner wall 42 of the mounting hole have a certain pressing effect, so as to maintain good contact between the electrical contact surfaces.
Further, in embodiment 1, the second elastic clamping portion is a second card 55 disposed on one side of the clamping body 521 and spaced apart from the first card 53, and the second card 55 has a second free end 551. The number of the second cards 55 may be 1 or more, and preferably, the number of the second cards 55 is 2. In the depth direction of the mounting hole 41, the abutting portion 54 is closer to the fixing portion 51 than the second free end 551. The distance H1 between the second free end 551 and the fixing portion 51 is greater than the depth T of the mounting hole 41, H1 > T allows the second card 55 to pass through the mounting hole 41, and the distance between the second free end 551 and the other side of the buckle body 521 is greater than the width D of the mounting hole 41, so that the second card 55 opens outwards after passing through the mounting hole 41, the second free end 551 exceeds the edge of the mounting hole 41, the PCB 4 is ensured not to be separated from the second card 55, and the purpose that the PCB 4 is clamped between the fixing portion 51 and the second elastic clamping portion is achieved.
Further, in embodiment 1, the buckle body 521 is provided with a through hole 522 having the same shape as the first card 53 and the second card 55, respectively, one end of the first card 53 and one end of the second card 55 are fixed to the edge of the through hole 522, and the other end of the first card 53 and the other end of the second card 55 are respectively provided with a first free end 551 and a second free end 551. The edge parts of one ends of the first clamping piece 53 and the second clamping piece 55 are connected with the buckle 52, and the rest parts are cut off from the buckle 52, so that the rest parts of the first clamping piece 53 and the second clamping piece 55 are outwards opened.
As shown in fig. 7, in example 1, the following conditions are satisfied:
（1）：H2 < T < H1
（2）：d < D < L1
since (1) H2< T < H1, when the buckle 52 is inserted into the mounting hole 41, the second card 55 passes through the mounting hole 41 and springs open freely to serve as a limit, and the first card 53 is partially left in the mounting hole 41 to contact with the inner wall 42 of the mounting hole. And (2) D < D < L1, the abutting part 54 has a certain pressing effect with the inner wall 42 of the mounting hole, and good contact between the electric contact surfaces is maintained. After being mounted as shown in fig. 7, the clip 52 is fixed relative to the PCB 4, does not fall off, and has a stable electrical contact.
As shown in fig. 8 and 9, in embodiment 2, the buckle body 521 protrudes towards two sides to form two first locking pieces 53 disposed oppositely, two opposite ends of the first locking piece 53 are connected to the buckle body 521, and the middle positions of the two first locking pieces 53 respectively protrude outwards to form two abutting portions 54 disposed oppositely. When the buckle 52 is not inserted into the mounting hole 41, the distance L2 between the two abutting portions 54 is greater than the width D of the mounting hole 41, and L2 > D realizes that the inner wall 42 of the mounting hole can press the abutting portions 54, so that the electrical connection between the abutting portions 54 and the inner wall 42 of the mounting hole is kept stable. The distance H4 between the abutting portion 54 and the fixing portion 51 is smaller than the depth T of the mounting hole 41, H4 < T ensures that the abutting portion 54 does not pass through the mounting hole 41 during the mounting process, and the abutting portion 54 maintains a good electric contact state with the mounting hole inner wall 42.
Preferably, in embodiment 2, the second elastic clamping portion is a third card 56 formed by extending the buckle body 521 to one side and having a third free end 561, and the third card 56 is arranged to be offset from the first card 53, it can be understood that the function of the third card 56 is the same as that of the second card 55 in embodiment 1. In the depth direction of the mounting hole 41, the abutting portion 54 is closer to the fixing portion 51 than the third free end 561.
In embodiment 2, the distance H3 between the third free end 561 and the fixing portion 51 is greater than the depth T of the mounting hole 41, and H3 > T ensures that the third card 56 can pass through the mounting hole 41, wherein the two first cards 53 are symmetrically arranged with the center line between one side and the other side of the buckle body 521, the distance L3 between the third free end 561 and the center line is greater than 1/2 of the width D of the mounting hole 41, so that the third card 56 is outwardly opened after passing through the mounting hole 41, and the third free end 561 exceeds the edge of the mounting hole 41, so that the PCB 4 is not separated from the third card 56, thereby achieving the purpose that the PCB 4 is clamped between the fixing portion 51 and the second elastic clamping portion.
Preferably, in embodiment 2, the two first cards 53 are formed by tearing the buckle body 521 to both sides, and the abutting portion 54 is formed by the position where the first card 53 is torn outwards, which has the advantages of simple structure and convenience in processing.
As shown in fig. 10, in example 2, the following conditions are satisfied:
（3）L2 > D
（4）L3 > D/2
（5）H4 < T < H3
as H4 < T < H3 (5) is satisfied, after the buckle 52 is inserted into the mounting hole 41, the two first cards 53 remain in the mounting hole 41; due to the fact that (4) L3 is larger than D/2, the third clamping piece 56 has a limiting effect, and the buckle 52 cannot fall off; since (3) L2 > D, the two first cards 53 are pressed by the inner wall 42 of the mounting hole in the mounting hole 41, maintaining good contact between the electrical contact surfaces. After being mounted as shown in fig. 7, the clip 52 is fixed relative to the PCB 4, does not fall off, and has a stable electrical contact.
