DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantages of the present application more clear and obvious, the present application is further described in detail below with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, the description of the known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application. Embodiment 1

[0035] The switching structure of the signal acquisition branch provided by the embodiment of the present application is shown in the figure. Figures 3 to 12 The switching structure 10 includes two solder pads at the ends and an anti-expansion structure 12 in the middle. In order to facilitate understanding and description, one of the two solder pads in the switching structure 10 is implemented as a first solder pad 11, and the other is implemented as a second solder pad 13. The first solder pad 11 is a solder pad connected with an aluminum connecting bar (not shown in the figure), and the second solder pad 13 is a solder pad connected with a signal acquisition circuit board 20. The anti-expansion structure 12 includes an anti-expansion part 121 and at least one reinforcing part 122. Exemplarily, Figures 3 to 12 The number of the reinforcing parts 122 shown in the figure is three. The anti-expansion part 121 has at least two bending segments and is connected with the upper and lower solder pads at the two ends, that is, the anti-expansion part 121 is in a wave shape or S shape, etc. The at least one reinforcing part 122 is connected with the anti-expansion part 121 at one end and with one of the solder pads at the other end or connected with the adjacent two bending segments of the anti-expansion part 121 at the two ends. In order to facilitate distinction and description, the reinforcing part 122 connected with the anti-expansion part 121 at one end and with one of the solder pads at the other end (i.e., as shown in the figure) is referred to as a first reinforcing part, and the reinforcing part 122 connected with the anti-expansion part 121 at the two ends (i.e., as shown in the figure) is referred to as a second reinforcing part. Figures 3 to 12The reinforcing portions 122 at the top and bottom ends shown are described as a first type of reinforcing portion, where the two ends of the reinforcing portion 122 are respectively connected between two adjacent bent sections of the anti-expansion portion 121 (i.e., as shown in the figure). Figures 3 to 12 The reinforcing portion 122 located in the middle of the vertical direction shown is described as a second type of reinforcing portion. When only one reinforcing portion 122 is provided on the anti-expansion structure 12, it can be either a first type of reinforcing portion or a second type of reinforcing portion. When two reinforcing portions 122 are provided on the anti-expansion structure 12, both can be first type of reinforcing portions, or one can be a first type of reinforcing portion and the other a second type of reinforcing portion. When the number of reinforcing portions 122 is at least three, depending on the number of bending segments, the reinforcing portions 122 may include both first type and second type of reinforcing portions, or all of them may be second type of reinforcing portions. Preferably, as shown... Figures 3 to 12 The anti-expansion structure 12 shown includes both a first-type reinforcing part and a second-type reinforcing part. Regarding the reinforcing part 122, as... Figures 3 to 12 As shown, any reinforcing part 122 includes at least one reinforcing segment 1221 and at least one micro-connection structure 1222. The width of the micro-connection structure 1222 (this width is perpendicular to the direction in which the two ends of the anti-expansion part 121 are connected to the pads, i.e., as shown) Figures 3 to 12 The width of the reinforcing segment 1221 (shown in the horizontal or left-right direction) should be smaller than that of the reinforcing segment 1221. An alternative embodiment, such as... Figures 3 to 7 and Figures 9 to 12 As shown, each reinforcing part 122 has only one micro-connection structure 1222. Another alternative embodiment, such as... Figure 8 As shown, a reinforcing section 122 has two micro-connection structures 1222. For the reinforcing section 1221, it can be as follows: Figures 3 to 7 , Figure 9 and Figure 10 The two reinforcing segments at both ends of the micro-connection structure 1222 shown can also be as follows: Figure 8 The three reinforcing segments 1221 connected by the two micro-connection structures 1222 can also be as follows: Figure 11 and Figure 12 As shown in the diagram, a reinforcing segment 1221 is provided. In this case, one end of the micro-connection structure 1222 is connected to the reinforcing segment 1221, and the other end is connected to the pad or the anti-expansion portion 121. Of course, the reinforcing portion 122 may also have other numbers of micro-connection structures 1222, such as three or more, or at least two or three reinforcing portions 122, or all reinforcing portions 122 may have three or more micro-connection structures 1222, which is also within the scope of protection of this embodiment. Furthermore, it should be noted that when the number of reinforcing segments 1221 is at least two, the length of the reinforcing segment 1221 is not limited and can be as follows: Figures 3 to 7 The lengths shown are consistent. Alternatively, as... Figure 9 andFigure 10 The long and short, that is, the length is inconsistent. In summary, the adapter structure of the embodiment of the application, compared with the prior art, that is Figure 1 And Figure 2 The anti-expansion structure 12 of the embodiment of the application further comprises a reinforcing portion 122 for reinforcing the entire anti-expansion structure 12, which is larger in size, and the reinforcing portion 122 is connected with the anti-expansion portion 121 and / or connected between adjacent bending sections of the anti-expansion portion 121, the reinforcing portion 122 plays a role in reinforcing the anti-expansion portion 121, so that the strength of the entire anti-expansion structure 12 is higher, and the shape is easier to control during processing and transportation, and use. In addition, due to the arrangement of the micro connecting structure 1222, the reinforcing portion 122 has a spring-like effect and good stretching performance, and is not easy to break during automatic feeding, and can be suitable for automatic feeding.

[0036] A preferred embodiment, the number of reinforcing portions 122 is at least two. Exemplarily, as Figures 3 to 12 The number of reinforcing portions 122 is three. According to one preferred embodiment of the embodiment of the application, at least one reinforcing portion 122 is provided with at least two micro connecting structures 1222. The stretching performance of the reinforcing portion 122 can be further improved. A preferred embodiment, the width of all reinforcing portions 122 is consistent, the stress is relatively uniform, and the processing is convenient, for example, all reinforcing portions 122 can be processed by punching with the same mold. As for the distribution of the reinforcing portion 122, a preferred embodiment, in the direction from the end of the anti-expansion portion 121 connected with one of the pads to the end connected with another pad, that is, as Figures 3 to 12 The upper and lower directions shown in Figures 3 to 12 The left and right sides, respectively. The reinforcing portions 122 are arranged on the left and right sides, which can make the stress on both sides of the anti-expansion portion 121 relatively uniform. As an alternative embodiment, at least two reinforcing portions 122 can be on the same side, that is, as Figures 3 to 12 The left or right side.

[0037] According to some preferred embodiments of the application, any reinforcing portion 122 and the corresponding bending section of the anti-expansion portion 121 enclose a hollow portion 123. Exemplarily, as Figures 3 to 12 It is shown that the anti-expansion structure 12 is provided with three hollow portions 123, and the three hollow portions 123 are in the direction from the end of the anti-expansion portion 121 connected with one of the pads (such as the first pad 11 at the upper end in the figure) to the end connected with another pad (such as the second pad 13 at the lower end shown in Figures 3 to 12 The direction is as Figures 3 to 12The hollow portions 123 are arranged in the up-down direction as shown. The shape of the hollow portions 123 is not particularly limited and described, and exemplary, Figures 3 to 12 In the embodiment shown, the hollow portions 123 include a substantially quadrangular hollow portion 123 and a substantially triangular hollow portion 123 from top to bottom. For the purpose of description and differentiation, the side of any reinforcing portion 122 facing the corresponding hollow portion 123, i.e. the inner side, is referred to as the first side, and the side of any reinforcing portion 122 facing away from the corresponding hollow portion 123, i.e. the outer side, is referred to as the second side. The micro connecting structure 1222 is defined by a first recessed portion 12221 formed on the first side and recessed toward the second side, and a second recessed portion 12222 formed on the second side and recessed toward the first side. That is, two opposite recessed portions are formed on the first side and the second side respectively, thereby forming the micro connecting structure 1222 with a width smaller than that of the reinforcing segment. Preferably, the first recessed portion 12221 and the second recessed portion 12222 of any micro connecting structure 1222 are symmetrical structures. The symmetrical arrangement is more uniform in stress and more convenient in processing. As an alternative embodiment, the second recessed portion 12222 and the first recessed portion 12221 of any micro connecting structure 1222 can also be asymmetrical structures, such as being slightly staggered in the up-down direction or having different sizes or shapes. As for the shape of the first recessed portion 12221 and the second recessed portion 12222, a semicircular arc shape as shown is preferred for the convenience of processing. As an alternative embodiment, the shape of the first recessed portion 12221 and the second recessed portion 12222 can also be any other shape, such as a triangular shape, a trapezoidal shape, a square shape, etc. Figures 3 to 12 As for the shape of the first recessed portion 12221 and the second recessed portion 12222, a semicircular arc shape as shown is preferred for the convenience of processing. As an alternative embodiment, the shape of the first recessed portion 12221 and the second recessed portion 12222 can also be any other shape, such as a triangular shape, a trapezoidal shape, a square shape, etc.

[0038] When the number of reinforcing portions 122 on the anti-swelling structure 12 is two or more, all the reinforcing portions 122 can be on the same vertical line in the up-down direction as shown, Figures 3 to 12 all the reinforcing portions 122 can not be on the same vertical line, or part of the reinforcing portions 122 can be on the same vertical line. As shown in Figure 3 and Figure 8 , Figure 9 and Figure 11 As shown in Figures 5 to 7 and Figure 10 As shown in Figure 3 and Figure 8 , Figure 9 and Figure 11 As shown in Figure 5As shown in the figure, the second side edge of the upper end of the two reinforcing portions 122 on the left side is in the same vertical line as the left side of one curved section, but the second side edge of the lower end of the reinforcing portion 122 is located between the left and right sides of the two adjacent curved sections at the lower end, that is, not connected to the left side of the corresponding curved section, but connected to the middle part of the corresponding curved section and not in the same vertical line as the upper reinforcing portion 122. Figures 6 to 7 and the figure, Figure 12 As shown in the figure, the second side edge of the two reinforcing portions 122 on the left side is not connected to the left side of the corresponding curved section, but is connected to the middle part of the corresponding curved section. Similarly, the reinforcing portion 122 on the right side can have the second side edge connected to the right side of the corresponding curved section or connected to the middle part of the corresponding curved section. The second side edge of the reinforcing portion 122 is wider than the whole anti-expansion structure 12 when connected to the side edge of the corresponding curved section compared to when connected to the middle part of the corresponding curved section, but the strength can be slightly weaker.

[0039] According to some preferred embodiments of the embodiments of the present application, the anti-expansion structure 12, in particular the anti-expansion portion 121, is further provided with a fuse 124. The purpose is to play a protection role against overcurrent, which is a structure that the prior art anti-expansion structure 12' does not have. Specifically, as shown in the figure, Figures 3 to 12 As shown in the figure, the fuse 124 extends along the curved anti-expansion portion 121 from the end of the anti-expansion portion 121 connected to one of the pads, such as the first pad, to the end of the anti-expansion portion 121 connected to the other pad, such as the second pad, that is, as shown in the figure, from top to bottom. Figures 3 to 12 As shown in the figure, the fuse 124 extends along the curved anti-expansion portion 121 from the end of the anti-expansion portion 121 connected to one of the pads, such as the first pad, to the end of the anti-expansion portion 121 connected to the other pad, such as the second pad, that is, as shown in the figure, from top to bottom.

Moreover, due to the existence of the micro connection structure 121, the reinforcing portion 122 is similar to a spring and has good stretchability, so that the anti-expansion structure 12 is more flat during the feeding process, can be suitable for automatic feeding, and can improve production efficiency. Moreover, the specifications (area) of the second pads 13 of all the switching structures 10 on the same FFC are the same, so as to ensure that the lengths of all the switching structures 10 are consistent and the sizes are uniform, and there is no need to distinguish between multiple specifications during production and installation, so that the switching structures 10 can be uniformly manufactured and managed.
