DETAILED DESCRIPTION

[0032] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. It should be noted that, unless otherwise stated, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by those skilled in the art to which the embodiments of the present application belong. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0033] It should be noted that the words first direction X, second direction Y and third direction Z in the present application are only used to more clearly illustrate the specific structure of the present application in conjunction with the drawings, and the present application is not limited thereto. The first direction X, the second direction Y and the third direction Z have an angle between each other; optionally, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0034] like Figures 1 to 3 As shown, an embodiment of the present application provides a connection structure 100, wherein the connection structure 100 includes a male plug 1 and a female plug 2, and the male plug 1 and the female plug 2 can be plugged into each other to achieve circuit conduction.

[0035] The male plug 1 is generally in a sheet-like structure and is parallel to a plane defined by the first direction X and the second direction Y.

[0036] The female plug 2 includes at least two connection terminals 21 , and each connection terminal 21 can be connected to the male plug 1 to realize circuit conduction for one circuit.

[0037] Each connection terminal 21 is generally in a sheet-like structure and is arranged at intervals along the first direction X. Each sheet-like structure is parallel to each other and perpendicular to the first direction X. Every two adjacent connection terminals 21 are connected by a connection portion 22, and the connection portion 22 can effectively maintain and fix the positions of the connection terminals 21 to ensure that there is no relative displacement between the connection terminals 21 during use, to ensure the structural and dimensional accuracy of the female plug 2, and thus to ensure the smooth and reliable plug-in matching between the female plug 2 and the male plug 1.

[0038] A slot 211 is formed on each connecting terminal 21, and the slot 211 passes through the corresponding connecting terminal 21 along the first direction X. Each connecting terminal 21 has a first side and a second side arranged opposite to each other along the second direction Y, and the slot 211 forms a notch on the first side of the corresponding connecting terminal 21 along the second direction Y. The notches of the slots 211 on each connecting terminal 21 are oriented in the same direction, that is, the slots 211 on each connecting terminal 21 correspond to each other along the first direction X, so as to cooperate and be used together for the insertion of the male plug 1; preferably, the projections of the slots 211 on each connecting terminal 21 along the first direction X overlap, so as to ensure that they can be smoothly inserted into the slots 211 of any number of connecting terminals 21 at the same time.

[0039] According to the use requirements, the male plug 1 is inserted into the slots 211 of at least two connecting terminals 21 to connect with the corresponding connecting terminals 21, which can effectively shunt the circulating circuit, thereby improving the overall current passing capacity of the connection structure 100 to meet the use requirements of large currents.

[0040] like Figures 1 to 3 As shown, the connection structure 100 provided by the present application, wherein the connection portion 22 is fixedly connected to the connection terminal 21 to ensure the connection reliability between the connection portion 22 and the connection terminal 21, thereby ensuring the connection portion 22 has an effect of maintaining the relative position between adjacent connection terminals 21.

[0041] Along the second direction Y, the connecting part 22 has two side surfaces opposite to each other, wherein the surface of the connecting part 22 on the side opposite to the slot along the second direction Y is flush with or protrudes from the surface of the second side of the connecting terminal 21, so that when the female plug 2 is installed on the circuit board, the connecting part 22 can contact the surface of the circuit board. On the one hand, the installation stability of the female plug 2 on the circuit board is improved, and on the other hand, the connecting part 22 can be used to realize the electrical connection between the female plug 2 and the circuit board. By adjusting the size of the connecting part 22, the contact area between the connecting part 22 and the circuit board can be adjusted, thereby ensuring the current flow area and meeting the use requirements of large current.

[0042] like Figures 1 to 3 As shown, the connection structure 100 provided by the present application, wherein, along the direction from the bottom of the slot 211 to the slot mouth of the slot 211, the size of the slot 211 along the third direction Z gradually increases; this is convenient for guiding the insertion of the male plug 1, so as to effectively reduce the difficulty of plugging and assembling the male plug 1 and the female plug 2.

[0043] like Figures 1 to 3As shown, the connection structure 100 provided by the present application, wherein clamping portions 212 are respectively provided on the groove walls on both sides of the slot 211 along the third direction Z at positions close to the slot openings, so as to clamp the male plug 1, thereby preventing the male plug 1 from escaping from the slot 211 and being separated from the male plug 1 when unnecessary, thereby ensuring the connection reliability between the male plug 1 and the female plug 2.

[0044] The figure takes two clamping parts 212 as an example. It should be noted that the number of the clamping parts 212 in the present application is not limited to two; the clamping parts 212 are arranged one by one along the third direction Z.

[0045] Along the third direction Z, the distance between the two clamping parts 212 is smaller than the size of the male plug 1 , that is, the male plug 1 is clamped between the two clamping parts 212 in an interference fit manner to effectively ensure the clamping effect of the clamping parts 212 .

[0046] Optionally, in the connection structure 100 provided by the present application, the difference between the size of the male plug 1 and the distance between the two clamping parts 212 along the third direction Z is greater than or equal to 2 mm, so as to further ensure the tolerance of the interference fit between the male plug 1 and the clamping part 212, thereby ensuring the clamping reliability.

[0047] like Figures 1 to 3 As shown, the connection structure 100 provided by the present application, wherein each connection terminal 21 is respectively provided with at least one positioning portion 23 on the second side along the second direction Y to realize the connection between the female plug 2 and the circuit board during the assembly process. Specifically, when in use, the male plug 1 can be connected to the electrical device or the power supply device through a conductive wire harness, and the female plug 2 is electrically connected to the circuit board, and the circuit is conducted by plugging the male plug 1 and the female plug 2.

[0048] like Figures 1 to 3 As shown, the connection structure 100 provided by the present application, wherein a support portion 24 is connected to at least one side of the connection terminal 21 along the third direction Z; by setting the support portion 24, it can abut against the surface of the circuit board when the female plug 2 is installed on the circuit board, so as to provide support and correction for the corresponding connection terminal 21, thereby preventing the connection terminal 21 from deflecting relative to the circuit board and affecting the quick connection with the male plug 1.

[0049] The projection of the support portion 24 along the third direction Z protrudes from at least one side of the projection of the connection terminal 21 along the third direction Z in the first direction X, so as to prevent the connection terminal 21 from swinging and deflecting along the first direction X.

[0050] Optionally, the support portion 24 extends from at least one side of the connection terminal 21 along the third direction Z and bends to extend toward the first direction X, roughly forming a rounded steel-shaped structure, which has the advantages of simple structure and easy processing.

[0051] Along the second direction Y, the surface of the support portion 24 facing the side opposite to the notch of the slot 211 is flush with or protrudes from the surface of the second side of the connecting terminal 21. When the female plug 2 is installed on the circuit board, it is ensured that the support portion 24 can abut against the circuit board to provide effective support for the connecting terminal 21.

[0052] like Figures 1 to 3 As shown, the connection structure 100 provided by the present application, wherein a guide portion 11 is formed on the side of the male plug 1 facing the female plug 2, and along the direction toward the female plug 2, the size of the guide portion 11 along the first direction X gradually decreases. By providing the guide portion 11, it is helpful to reduce the difficulty of plugging and matching the male plug 1 and the female plug 2, and it is convenient for the staff to quickly complete the plugging and matching of the male plug 1 and the female plug 2.

[0053] The connection structure 100 provided in the present application, wherein along the first direction X, the ratio of the distance between the two connection terminals 21 farthest apart to the maximum size of the portion of the male plug 1 that is mated with the female plug 2 is 2:3 to 3:4, so as to provide uniform and effective support for the male plug 1 through each connection terminal 21, thereby reducing the situation in which the male plug 1 deviates along the first direction X and separates from the female plug 2.

[0054] On the other hand, Figures 4 to 6 As shown, an embodiment of the present application provides a circuit board assembly, wherein the circuit board assembly includes a circuit board body 200 and the connection structure 100 as described above, and the female end plug 2 of the connection structure 100 is connected and electrically connected to the circuit board body 200.

[0055] Among them, a conductive layer 201 is provided on the circuit board body 200, and the connecting part 22 of the female plug 2 is connected and electrically connected to the conductive layer 201 to realize the electrical connection between the female plug 2 and the circuit board; optionally, the conductive layer 201 can be a copper layer or other metal layer covered on the surface of the circuit board body 200.

[0056] The circuit board body 200 is provided with a positioning hole 202 , and the positioning portion 23 of the connecting terminal 21 of the female plug 2 is plugged and positioned in the positioning hole 202 to achieve a positioning connection between the female plug 2 and the circuit board body 200 .

[0057] The circuit board assembly of the embodiment of the present application has a connection structure 100 in which the female plug 2 includes at least two connection terminals 21, and the male plug 1 is inserted into the slots 211 of at least two connection terminals 21 to connect with the corresponding connection terminals 21 according to usage requirements.
