然而，当中继电连接器的导电端子在与电连接器的公针对插时，若中继连接器与电连接器并非位于同一水平面，则在对插上会受到空间限制，操作人员将无法顺利地连接电连接器与中继连接器，并且有可能在对插时损坏了中继电连接器的导电端子及/或电连接器的公针
[0014]综合以上所述，于本实用新型中，大电流浮动连接结构的塑料壳体定义出浮动空间，且导电弹性端子的固定部可抵接塑料壳体的固定区以稳固导电弹性端子于塑料壳体中，并且当大电流浮动连接结构的公针件插入至塑料壳体中以电性连接导电弹性端子时，公针件可经由塑料壳体的浮动空间沿第一方向及/或垂直于第一方向的第二方向移动以降低对插时的空间要求。也就是说，即使大电流浮动连接结构的导电弹性端子与公针件并非位于同一水平面上时(即两者未完全对齐)，导电弹性端子仍可顺利与公针件对插，并且对插后的连接结构仍具有一定的移动空间。此外，大电流浮动连接结构只需要使用一个壳体(即塑料壳体)就可实现浮动连接的效果，可取代传统电连接结构需要使用两个壳体进行浮动连接的配置。

Abstract
Description
Technical Field
[0001] This utility model relates to an electrical connection structure, and more particularly to a high-current floating connection structure that allows male pins to move along a first direction and / or a second direction perpendicular to the first direction via a floating space in a plastic housing, thereby reducing the insertion space requirement and achieving a floating connection effect using only one housing. Background Technology
[0002] Generally, traditional relay connectors serve as electrical components connecting a printed circuit board to another electrical connector. However, when the conductive terminals of the relay connector are mated with the male pins of the electrical connector, if the relay connector and the electrical connector are not on the same horizontal plane, the mating will be constrained by space. Operators will be unable to connect the electrical connector and the relay connector smoothly, and may damage the conductive terminals of the relay connector and / or the male pins of the electrical connector during mating. In other words, the inability to float reduces the application value of relay connectors. Utility Model Content
[0003] One technical aspect of this utility model is a high-current floating connection structure, in which the male pin can move along a first direction and / or a second direction perpendicular to the first direction through the floating space of the plastic shell to reduce the space requirements during insertion, and only one shell is used to achieve the floating connection effect, replacing the traditional electrical connection structure that requires two shells for floating connection.
[0004] This utility model provides a high-current floating connection structure, which includes a plastic housing, a conductive elastic terminal, and a male pin. The plastic housing has a first opening and a second opening opposite to the first opening, wherein the first opening defines a floating space, and the plastic housing has a fixing area adjacent to the second opening. The conductive elastic terminal has a fixing portion and a first main body portion connecting the fixing portion, wherein the fixing portion of the conductive elastic terminal abuts against the fixing area of the plastic housing to secure the conductive elastic terminal to the plastic housing, and the conductive elastic terminal further has two opposing second main body portions, the first main body portion being disposed on one side of the two second main body portions, and the first main body portion and the second main body portion being connected to a connecting section of the conductive elastic terminal. The male pin has a short side and a long side adjacent to the short side and is inserted into the plastic housing to contact the conductive elastic terminal, such that the male pin moves along a first direction and / or a second direction perpendicular to the first direction via the floating space of the plastic housing.
[0005] According to one embodiment of the present invention, the first direction and the second direction are both located on the same horizontal plane, and a portion of the conductive elastic terminal is exposed from the first opening of the plastic shell. The conductive elastic terminal further has a welding end for connecting the fixing part, and the welding end of the conductive elastic terminal extends to the outside of the second opening of the plastic shell.
[0006] According to one embodiment of the present invention, the first main body of the conductive elastic terminal is disposed between two second main bodies, and the two second main bodies of the conductive elastic terminal are used to clamp the short side of the male needle in a first direction so that the male needle can float in the floating space of the plastic shell.
[0007] According to one embodiment of the present invention, the first main body of the conductive elastic terminal is used to contact the long side of the male pin in the second direction so that the male pin can float in the floating space of the plastic shell.
[0008] According to one embodiment of the present invention, the connecting segment of the above-mentioned conductive elastic terminal is vertically connected to the first main body and laterally connected to the second main body.
[0009] According to one embodiment of the present invention, the above-mentioned conductive elastic terminal further has a third main body portion, which is disposed on one side of the first main body portion and located between the two second main body portions. The third main body portion is used to contact the long side of the male needle in the second direction so that the male needle can float in the floating space of the plastic shell.
[0010] According to one embodiment of the present invention, the connecting segment of the above-mentioned conductive elastic terminal is vertically connected to the first main body, the second main body, and the third main body.
[0011] According to one embodiment of the present invention, the above-mentioned high-current floating connection structure further includes a male terminal housing. The male terminal housing contacts the male pin and has a receiving space, wherein when the male terminal housing and the male pin are inserted into the plastic housing so that the male pin contacts the conductive elastic terminal, the second body portion and the third body portion of the conductive elastic terminal are located in the receiving space of the male terminal housing.
[0012] According to one embodiment of the present invention, the male end housing has an extension to form an accommodating space, and when the male end housing and the male pin are inserted into the plastic housing, the extension of the male end housing is used to move in the floating space of the plastic housing.
[0013] According to one embodiment of the present invention, the male needle component floats in the floating space along a first direction for a first distance, and the male needle component floats in the floating space along a second direction for a second distance, the first distance and the second distance being between 0.5 mm and 1.5 mm.
[0014] In summary, in this invention, the plastic shell of the high-current floating connection structure defines a floating space, and the fixing part of the conductive elastic terminal can abut against the fixing area of the plastic shell to secure the conductive elastic terminal within the plastic shell. Furthermore, when the male pin of the high-current floating connection structure is inserted into the plastic shell to electrically connect the conductive elastic terminal, the male pin can move along a first direction and / or a second direction perpendicular to the first direction via the floating space of the plastic shell, reducing the space requirements during insertion. That is, even if the conductive elastic terminal and the male pin of the high-current floating connection structure are not on the same horizontal plane (i.e., they are not fully aligned), the conductive elastic terminal can still be smoothly inserted into the male pin, and the connection structure after insertion still has a certain amount of room to move. In addition, the high-current floating connection structure only requires one shell (i.e., a plastic shell) to achieve the floating connection effect, replacing the traditional electrical connection structure that requires two shells for floating connection.

[0029] Please refer to Figures 1 to 5 , Figure 1 A perspective view of a high-current floating connection structure 100 according to an embodiment of the present invention is shown. Figure 2 Draw Figure 1 Top view of the high-current floating connection structure 100 Figure 3 A perspective view of a conductive elastic terminal 120 according to an embodiment of the present invention is shown. Figure 4 A cross-sectional view of a high-current floating connection structure 100 according to an embodiment of the present invention is shown, and Figure 5 A cross-sectional view of a high-current floating connection structure 100 according to an embodiment of the present invention is shown from another perspective. Figures 1 to 5 In this high-current floating connection structure 100, a plastic housing 110, a conductive elastic terminal 120, and a male pin 130 are included. The plastic housing 110 of the high-current floating connection structure 100 has a first opening O1 and a second opening O2 relative to the first opening O1. For example, the upper end of the plastic housing 110 has the first opening O1, and the lower end of the plastic housing 110 has the second opening O2. The first opening O1 of the plastic housing 110 defines a floating space A, and the plastic housing 110 has a fixed area 112 adjacent to the second opening O2.
[0030] In some embodiments, the conductive elastic terminal 120 has a fixing portion 122 and a first main body portion 124 connecting the fixing portion 122. For example, the fixing portion 122 of the conductive elastic terminal 120 abuts against the fixing area 112 of the plastic housing 110 to secure the conductive elastic terminal 120 in the plastic housing 110. Furthermore, the conductive elastic terminal 120 also has two opposing second main body portions 126, and the first main body portion 124 is disposed on one side of the two second main body portions 126. Specifically, the front and rear sides of the conductive elastic terminal 120 may have second main body portions 126, while the left and right sides of the conductive elastic terminal 120 may have first main body portions 124. The first main body portions 124 and second main body portions 126 of the conductive elastic terminal 120 surround to form a structural space for the insertion of the male pin 130. Furthermore, the first main body portions 124 and second main body portions 126 of the conductive elastic terminal 120 are connected to the connecting section 127 of the conductive elastic terminal 120.
[0031] In some embodiments, the male pin 130 has a short side 131 and a long side 133 adjacent to the short side 131, and the male pin 130 is used to insert into the plastic housing 110 to contact the conductive elastic terminal 120. In this embodiment, the male pin 130 is inserted into the plastic housing 110 to contact the first body portion 124 and the second body portion 126 of the conductive elastic terminal 120, such that the male pin 130 can move along a first direction D1 and / or a second direction D2 perpendicular to the first direction D1 via the floating space A of the plastic housing 110. Specifically, the first direction D1 and the second direction D2 are both located on the same horizontal plane, and a portion of the conductive elastic terminal 120 is exposed from the first opening O1 of the plastic housing 110, and the conductive elastic terminal 120 further has a solder end 121 for connecting the fixing portion 122, and the solder end 121 of the conductive elastic terminal 120 extends outside the second opening O2 of the plastic housing 110.
[0032] In some embodiments, the male needle 130 can float a first distance C1 along a first direction D1 in the floating space A of the plastic housing 110, and the male needle 130 can also float a second distance C2 along a second direction D2 in the floating space A. That is, the male needle 130 moves a first distance C1 to the left and a first distance C1 to the right along the first direction D1, and the male needle 130 can also float a second distance C2 forward and a second distance C2 backward along the second direction D2 in the floating space A, and the first distance C1 and the second distance C2 are between 0.5 mm and 1.5 mm, for example, 1 mm.
[0033] Specifically, the plastic housing 110 of the high-current floating connection structure 100 defines a floating space A, and the fixing portion 122 of the conductive elastic terminal 120 can abut against the fixing area 112 of the plastic housing 110 to secure the conductive elastic terminal 120 in the plastic housing 110. When the male pin 130 of the high-current floating connection structure 100 is inserted into the plastic housing 110 to electrically connect the conductive elastic terminal 120, the male pin 130 can move along the first direction D1 and / or the second direction D2 perpendicular to the first direction D1 through the floating space A of the plastic housing 110 to reduce the space requirement during insertion. That is to say, even if the conductive elastic terminal 120 and the male pin 130 of the high-current floating connection structure 100 are not located on the same horizontal plane (i.e., they are not fully aligned), the conductive elastic terminal 120 can still be smoothly inserted into the male pin 130, and the connection structure after insertion still has a certain amount of movement space. Furthermore, the high-current floating connection structure 100 only requires one housing (i.e., plastic housing 110) to achieve the floating connection effect, which can replace the traditional electrical connection structure that requires two housings for floating connection.
[0034] In some embodiments, the first main body portion 124 of the conductive elastic terminal 120 is disposed between two second main body portions 126, and the two second main body portions 126 of the conductive elastic terminal 120 are used to clamp the short side surface 131 of the male pin 130 in the first direction D1, so that the male pin 130 floats in the floating space A of the plastic housing 110. Furthermore, the first main body portion 124 of the conductive elastic terminal 120 is used to contact the long side surface 133 of the male pin 130 in the second direction D2, so that the male pin 130 floats in the floating space A of the plastic housing 110. The connecting segment 127 of the conductive elastic terminal 120 is vertically connected to the first main body portion 124, and the connecting segment 127 of the conductive elastic terminal 120 is laterally connected to the second main body portion 126. The first main body portion 124 and the second main body portion 126 of the conductive elastic terminal 120 in the high-current floating connection structure 100 enable the conductive elastic terminal 120 to carry a large current.

Figure 7 A cross-sectional view of a high-current floating connection structure 100a according to another embodiment of the present invention is shown, and Figure 8 A cross-sectional view of a high-current floating connection structure 100a according to another embodiment of the present invention is shown from another perspective. Figures 6 to 8 middle, Figure 7 and Figure 8 The high-current floating connection structure 100a shown is... Figure 4 and Figure 5 The difference in the high-current floating connection structure 100a shown is that the conductive elastic terminal 120a of the high-current floating connection structure 100a further has a third main body portion 128a. The third main body portion 128a of the conductive elastic terminal 120a is disposed on one side of the first main body portion 124a and located between the two second main body portions 126a, and the third main body portion 128a of the conductive elastic terminal 120a is used to contact the long side surface 133 of the male pin member 130 in the second direction D2, so that the male pin member 130 floats in the floating space A of the plastic housing 110. In addition, the connecting segment 127a of the conductive elastic terminal 120a of the high-current floating connection structure 100a is vertically connected to the first main body portion 124a, the second main body portion 126a and the third main body portion 128a. The first main body portion 124a, the second main body portion 126a and the third main body portion 128a of the conductive elastic terminal 120a of the high-current floating connection structure 100a enable the conductive elastic terminal 120a to carry a larger current.
[0036] Please refer to Figures 9 to 10 , Figure 9A cross-sectional view of a high-current floating connection structure 100b according to another embodiment of the present invention is shown. Figure 10 A cross-sectional view of a high-current floating connection structure 100b according to another embodiment of the present invention is shown from another perspective. Figures 9 to 10 middle, Figure 9 and Figure 10 The high-current floating connection structure 100b shown is... Figure 4 and Figure 5 The high-current floating connection structure 100b shown differs in that it further includes a male terminal housing 140. The male terminal housing 140 of the high-current floating connection structure 100b contacts the male pin 130 and has a receiving space B. When the male terminal housing 140 and the male pin 130 of the high-current floating connection structure 100b are inserted into the plastic housing 110 such that the male pin 130 contacts the conductive elastic terminal 120a, the second body portion 126a and the third body portion 128a of the conductive elastic terminal 120a are located within the receiving space B of the male terminal housing 140. Furthermore, the male terminal housing 140 of the high-current floating connection structure 100b has an extension 142 to form the receiving space B, and when the male terminal housing 140 and the male pin 130 of the high-current floating connection structure 100b are inserted into the plastic housing 110, the extension 142 of the male terminal housing 140 is used to move within the floating space A of the plastic housing 110.
