In this embodiment of the present application, the plurality of connection portions are sequentially connected to realize connection of the plurality of units, the corresponding elastic pieces between the adjacent connectors are contacted and connected, the first elastic pieces of any connector have the same structure, the second elastic pieces of any connector have the same structure, for example, for the connector 100 shown in fig. 1 and fig. 2, the connector adjacent to the first elastic pieces includes the first elastic pieces having the first exposed portions and/or the second elastic pieces having the second exposed portions, the first exposed portions of the adjacent connectors are contacted and connected with the second exposed portions 1031 of the connector 100, and the second exposed portions of the adjacent connectors are contacted and connected with the first exposed portions 1021 of the connector 100.

In the embodiment of the present application, when the first surface 101A and the first adjacent connector are connected, the connector 100 is in three-point contact with the first exposed portion 1021 of the connector 100 and the second exposed portion of the first adjacent connector, and when the connector 100 is connected with the second surface 101B and the second adjacent connector, the second exposed portion 1031 of the connector 100 is in three-point contact with the first exposed portion of the second adjacent connector.

According to the embodiment, the corresponding shrapnel of the adjacent connectors are in three-point contact, so that the contact resistance can be reduced, the contact performance can be improved, and the connection stability and the mechanical strength resistance can be enhanced by adding and connecting the contacts.

It should be noted that three-point contact is understood in this application to be contact at three locations, which may be points, lines, planes.

In one or more embodiments, as shown in fig. 1, the number of the first elastic pieces 102 is plural, and the plural first elastic pieces 102 are arranged in the first direction (x direction) in the housing 101; as shown in fig. 2, the number of the second elastic pieces 103 is plural, and the plural second elastic pieces 103 are arranged in the first direction x in the housing 101.

It should be noted that the first elastic piece and the second elastic piece in fig. 5 respectively belong to two adjacent connectors, and similarly, the first elastic piece and the second elastic piece in fig. 6 respectively belong to two adjacent connectors.

As shown in fig. 3, the first exposed portion 1021 is a sheet-like body, and as shown in fig. 4, the second exposed portion 1031 includes a contact piece 10311 and a pair of clips 10312, and as shown in fig. 5 and 6, the contact piece 10311 is in contact with the front surface of the first exposed portion 1021 of the second adjacent connector, and the pair of clips 10312 are in contact with both side surfaces 1021A and 1021B of the first exposed portion 1021 of the second adjacent connector, respectively.

However, the present application is not limited thereto, and the first exposed portion and the second exposed portion may have other shapes, and the present application is not limited thereto, as long as the corresponding first exposed portion and second exposed portion of the adjacent connector can be in three-point contact.

In one or more embodiments, as shown in fig. 4, 5 and 6, the abutment plate 10311 is a planar elastic plate, so that, during assembly, the first exposed portion can smoothly slide on the abutment plate 10311 of the second exposed portion, thereby facilitating assembly, but the application is not limited thereto, and the abutment plate may have other shapes.

In one or more embodiments, as shown in fig. 4, the pair of clips 10312 includes a first clip 10312a and a second clip 10312b, where the first clip 10312a and the second clip 10312b are disposed on two sides S1 and S2 (see fig. 6) of the abutment sheet 10311, respectively. By forming the second exposed portion in the shape of a groove by the contact piece 10311 and the pair of clips 10312 on both sides, reliable contact between the first exposed portion and the second exposed portion can be achieved.

In the embodiment of the present application, as shown in fig. 6, the first clip 10312a and the second clip 10312b are respectively provided at the positions of the both sides S1 and S2 of the abutting piece 10311 and do not contact with the abutting piece 10311, whereby the groove-like opening size formed by the abutting piece 10311 and the pair of clips 10312 of the both sides is adjustable, and even if there is a tolerance in the size of the first exposed portion, the assembly between the first exposed portion and the second exposed portion can be smoothly performed, and the reliable contact between the first exposed portion and the second exposed portion can be ensured.

However, the present application is not limited thereto, for example, the first clip and the second clip are respectively disposed at two sides of the abutment piece and connected with the abutment piece, thereby having a simple structure.

Fig. 7 is another schematic view of the first elastic piece according to the embodiment of the present application.

In one or more embodiments, as shown in fig. 7, the thickness of the side surfaces 1021A, 1021B of the arcuate sheet-like body as the first exposed portion 1021 is greater than the thickness of the central portion C, whereby by increasing the area of the side surface of the first exposed portion 1021, the area of the first exposed portion 1021 in contact with the pair of clips can be increased, and the contact stability can be further improved.

In the embodiment of the present application, the side areas of the side surfaces 1021A, 1021B of the first exposed portion 1021 may be increased by punching or bending, which is not limited in this application, and other manners may be adopted.

Fig. 8 is another schematic view of the second spring according to the embodiment of the present application.

In one or more embodiments, as shown in fig. 8, the distance D between the proximate ends of the pair of clips 10312 is greater than the distance D between the proximate intermediate positions of the pair of clips 10312. Thus, the pair of clips 10312 have a shape with a large outer diameter and a small inner diameter, and the first exposed portion can be smoothly slid in, thereby facilitating assembly work.

In the embodiment of the present application, in a natural state, that is, in a case where the first exposed portion is not assembled in the second exposed portion, the distance D between the adjacent ends of the pair of clips 10312 should be larger than the width of the first exposed portion, and the distance D between the adjacent intermediate positions of the pair of clips 10312 should be smaller than the width of the first exposed portion, thereby enabling easy sliding-in of the first exposed portion and enabling reliable contact between the first exposed portion and the second exposed portion.

In one or more embodiments, as shown in fig. 8, any one of a pair of clips 10312 includes: a straight plate-shaped main body m and a guide portion g, the main body m contacts with the side surface of the first exposed portion, the guide portion g is positioned at the end of the main body m, and an included angle α is formed between the guide portion g and the main body m, so that a distance D between the ends of the pair of clips 10312 is large. That is, the guide portion g is an inclined plate-like body with respect to the main body portion m, so that the opening of the pair of clips 10312 is large, and the first exposed portion can be guided to slide in, thereby facilitating the assembly work.

In one or more embodiments, as shown in fig. 3, the first elastic sheet 102 further includes a first fixing portion 1022 fixed to the housing, a first welding portion 1023 located at one end of the first fixing portion 1022, and a first elastic arm 1024 located at the other end of the first fixing portion, and the first exposed portion 1021 is disposed on the first elastic arm 1024.

In this second contact state, three-point contact is achieved between the first exposed portion 1021 and the second exposed portion 1031. In this second contact state, the first exposed portion 1021 can continue to move in the sliding direction with respect to the second exposed portion 1031 until the first exposed portion 1021 and the second exposed portion 1031 reach the mounting alignment, that is, the full contact state shown in fig. 12 is entered.

As shown in fig. 12, in the full contact state, the first exposed portion 1021 and the second exposed portion 1031 are in a three-point contact state, and the mounting alignment is achieved. Thereby, the connection between the connector 100a and the connector 100b is completed.
