The circuit connection structures in printed circuit boards mainly include pin headers and female headers, which are connected after the pin headers and female headers are plugged in. In the process of manually or mechanically inserting the pin header into the female header, the pin header needs to be inserted into the matching female header, but due to operational errors and other reasons, there is a situation where the pin header is inserted into the wrong female header, which will cause the circuit structure to fail or even short-circuit. Utility Model Content
[0003] The technical problem to be solved by the present application is to provide an anti-reverse insertion connection structure and a circuit structure, which can eliminate the risk of a pin header being inserted into a wrong female header.
[0004] To solve the above technical problems, the present application provides an anti-reverse plug-in connection structure, including a first plug-in board and a second plug-in board, the first plug-in board including a first group of pins and a second group of pins relatively arranged in a first direction, the first group of pins and the second group of pins each including a plurality of pins arranged at intervals in the second direction, the second plug-in board including a first group of female headers and a second group of female headers relatively arranged in the first direction, the first group of female headers and the second group of female headers each including a plurality of sockets arranged at intervals in the second direction, wherein the pins in the first group of pins and the pins in the second group of pins are staggered in the second direction, and the sockets in the first group of female headers and the sockets in the second group of female headers are staggered in the second direction.
[0005] In an embodiment of the present application, the first group of needle rows includes at least two rows of needle rows arranged adjacent to each other in the first direction, and the second group of needle rows includes at least two rows of needle rows arranged adjacent to each other in the first direction.
[0006] In one embodiment of the present application, the first group of bus bars includes at least two rows of bus bars arranged adjacent to each other in the first direction, and the second group of bus bars includes at least two rows of bus bars arranged adjacent to each other in the first direction.
[0007] In one embodiment of the present application, the number of pins in the first group of pin rows is greater than the number of pins in the second group of pin rows, and the difference in number is a first preset difference.
[0008] In one embodiment of the present application, the number of pins in the first group of pin rows that is equal to the first preset difference is empty pins.
[0009] In one embodiment of the present application, the number of the jacks in the first group of female connectors is greater than the number of the jacks in the second group of female connectors, and the difference in number is a second preset difference.
[0010] In one embodiment of the present application, the number of jacks in the first group of female headers equal to the second preset difference is empty pins.
[0011] In an embodiment of the present application, the first group of needles are symmetrical about a first straight line in the second direction, and the second group of needles are symmetrical about the first straight line in the second direction.
[0012] In an embodiment of the present application, the first group of busbars are symmetrical about the second straight line in the second direction, and the second group of busbars are symmetrical about the second straight line in the second direction.

[0033] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of the present application. For ordinary technicians in this field, the present application can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.
[0034] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.
[0035] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values of the parts and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0036] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0037] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0038] In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and cannot be understood as limiting the scope of protection of this application. In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article. In addition, it is required to understand this application not only by the actual terms used, but also by the meaning implied by each term.

Electronic components (such as the micro control unit 300 mentioned above) can be arranged on the main body 110, and the pins can be connected to the electronic components on the main body 110.
[0043] exist Figures 1 to 4 In the embodiment, the number of rows of the pins in the first group of pins 120 and the number of rows of the pins in the second group of pins 130 are both two rows, but it should be understood that the number of rows of the pins in the first group of pins 120 and the number of rows of the pins in the second group of pins 130 in the present application is not limited to two rows, for example, it can also be one row, three rows or four rows, etc. In addition, the number of pins in each row of pins is not limited to the above embodiment, and can be set according to requirements.
[0044] refer to Figure 3 As shown, the second plugboard 200 includes a main body 210, a first group of female headers 220 and a second group of female headers 230. The first group of female headers 220 and the second group of female headers 230 are relatively arranged on the main body 210 along the first direction D1. The first group of female headers 220 includes two rows of female headers arranged adjacently along the first direction D1: a first row of female headers 221 and a second row of female headers 222. The first row of female headers 221 includes a plurality of sockets 221a arranged at intervals along the second direction D2, and the second row of female headers 222 includes a plurality of sockets 222a arranged at intervals along the second direction D2.
[0045] Similarly, the second group of female connectors 230 includes two rows of female connectors arranged adjacent to each other along the first direction D1: a first row of female connectors 231 and a second row of female connectors 232. The first row of female connectors 231 includes a plurality of sockets 231a arranged at intervals along the second direction D2, and the second row of female connectors 232 includes a plurality of sockets 232a arranged at intervals along the second direction D2.
[0046] exist Figures 1 to 4 In the embodiment, the number of rows of the first group of female headers 220 and the number of rows of the second group of female headers 230 are both two rows, but it should be understood that the number of rows of the first group of female headers 220 and the number of rows of the second group of female headers 230 in the present application are not limited to two rows, for example, they can also be one row, three rows or four rows, etc. In addition, the number of jacks in each row of female headers is not limited to the above embodiment, and can be set according to requirements.
[0047] like Figure 4 As shown, the first group of pin headers 120 and the second group of pin headers 130 are respectively inserted into the first group of female headers 220 and the second group of female headers 230 , thereby achieving the connection between the first plugboard 100 and the second plugboard 200 .
[0048] refer to Figure 2As shown, the pins (121a and 122a) in the first group of pin headers 120 and the pins (131a and 132a) in the second group of pin headers 130 are arranged in a staggered manner in the second direction D2. In other words, the projection of the pins in the first group of pin headers 120 along the first direction D1 does not overlap with the pins in the second group of pin headers 130.
[0049] exist Figure 2 In the embodiment, the number of pins in the first group of pins 120 is greater than the number of pins in the second group of pins 130, and the difference between the two is a first preset difference. Specifically, the number of pins in the first group of pins 120 is 14, the number of pins in the second group of pins 130 is 12, and the difference between the two is 2 (that is, the first preset difference is 2). It should be noted that the first preset difference is not limited to 2, for example, it can also be 1, 3, 4 or 5. The first group of pins 120 is symmetrical about the first straight line in the second direction D2, and the second group of pins 130 is also symmetrical about the first straight line in the second direction D2. Assuming that the first group of pins 120 is translated as a whole along the first direction D1 to the position of the second group of pins 130, since the first group of pins 120 and the second group of pins 130 are both symmetrical about the first straight line, the pins in the first group of pins 120 will not contact the pins in the second group of pins 130. In this way, the pins in the first group of pin headers 120 and the pins in the second group of pin headers 130 are staggered in the second direction D2. The first straight line is parallel to the first direction D1.
[0050] In some embodiments, the first group of pins 120 having the first preset difference number of pins are empty pins, and there is no electrical connection between the empty pins and the external connection. Figure 2 In the embodiment of the present invention, the first group of pins 120 has two pins that are empty. Preferably, the two pins are arranged Figure 2 The top or bottom position.
[0051] refer to Figure 3 As shown, the sockets (221a and 222a) in the first group of female connectors 220 and the sockets (231a and 232a) in the second group of female connectors 230 are arranged in a staggered manner in the second direction D2. In other words, the projection of the sockets in the first group of female connectors 220 along the first direction D1 does not overlap with the sockets in the second group of female connectors 230.
[0052] exist Figure 3In the embodiment of the present invention, the number of jacks in the first group of female row 220 is greater than the number of jacks in the second group of female row 230, and the difference between the two is a second preset difference. Specifically, the number of jacks in the first group of female row 220 is 14, the number of jacks in the second group of female row 230 is 12, and the difference between the two is 2 (that is, the second preset difference is 2). It should be noted that the second preset difference is not limited to 2, for example, it can also be 1, 3, 4 or 5. The first group of female row 220 is symmetrical about the second straight line in the second direction D2, and the second group of female row 230 is also symmetrical about the second straight line in the second direction D2. Assuming that the first group of female row 220 is translated as a whole along the first direction D1 to the position of the second group of female row 230, since the first group of female row 220 and the second group of female row 230 are both symmetrical about the second straight line, the jacks in the first group of female row 220 will not contact the jacks in the second group of female row 230. In this way, the insertion holes in the first group of female connectors 220 and the insertion holes in the second group of female connectors 230 are arranged in a staggered manner in the second direction D2. The second straight line is parallel to the first direction D1.
[0053] In some embodiments, the first group of female headers 220 has a second preset difference number of jacks as empty pins, and there is no electrical connection between the empty pins and the external connection. Figure 3 In the embodiment of the present invention, the first group of female headers 220 has two jacks with empty pins. Preferably, the two jacks are arranged at Figure 3 The top or bottom position.
[0054] Next, combine Figure 5 and Figure 6 The technical effect of the anti-reverse plug-in connection structure of the present application is described. Figure 5 is a top view schematic diagram of a connection structure in the prior art, Figure 6 It is a schematic top view of a second plugboard in the prior art.
[0055] refer to Figure 5 As shown, Figure 2 Similarly, the connection structure in the prior art also has a first group of pins 410 and a second group of pins 420 arranged opposite to each other in the first direction D1. The first group of pins 410 has two adjacent rows of pins: a first row of pins 411 and a second row of pins 412. The second group of pins 420 also has two adjacent rows of pins: a first row of pins 421 and a second row of pins 422. Figure 5 and Figure 2 The differences include: the projection of the pins in the first group of pins 410 in the first direction D1 overlaps with the pins in the second group of pins 420, that is, the pins in the first group of pins 410 and the pins in the second group of pins 420 are not staggered as in the present application.
[0056] refer to Figure 6As shown, Figure 3 Similarly, the second plugboard in the prior art also has a first group of female connectors 430 and a second group of female connectors 440 that are relatively arranged in the first direction D1. The first group of female connectors 430 has two adjacent rows of female connectors: a first row of female connectors 431 and a second row of female connectors 432. The second group of female connectors 440 has two adjacent rows of female connectors: a first row of female connectors 441 and a second row of female connectors 442. Figure 6 and Figure 3 The differences include: the projection of the sockets in the first group of female headers 430 in the first direction D1 overlaps with the sockets in the second group of female headers 440, that is, the pins in the first group of female headers 430 and the pins in the second group of female headers 440 are not staggered as in the present application.
[0057] Combined with reference Figure 5 and Figure 6 As shown, in a correct situation, the first set of pin headers 410 and the second set of pin headers 420 are respectively inserted into the first set of female headers 430 and the second set of female headers 440. Figure 5 The first group of pins 410 and the second group of pins 420 are symmetrical. Figure 6 The first group of female row 430 and the second group of female row 440 are symmetrical, or there is no staggered arrangement as mentioned above. Figure 5 After the first plug plate is rotated 180°, the first group of pin headers 410 and the second group of pin headers 420 can be respectively inserted into the second group of female headers 440 and the first group of female headers 430. This leads to the risk of inserting the pin headers into the wrong female headers in some cases (such as operator or mechanical operation errors).
[0058] In contrast to this application, reference Figures 2 to 4 As shown in the lock, since the pins in the first group of pin headers 120 are arranged in a staggered manner with the pins in the second group of pin headers 130, and the sockets in the first group of female headers 220 are arranged in a staggered manner with the sockets in the second group of female headers 230, when Figure 2 After the first plugboard 100 is rotated 180°, the first group of pins 120 cannot be inserted into the second group of female headers 230, and the second group of pins 130 cannot be inserted into the first group of female headers 220. In this way, the risk of inserting the pins into the wrong female headers can be eliminated.
