[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present application.

In addition, the terms “first”, “second”, “third” are only for the purpose of description, and cannot be understood as indicating or implying relative importance. ​​

[0031] In the description of the embodiments of the present application, it should be noted that unless specifically defined and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0032] In the following Figures 1 to 3 The embodiments of the present application propose a connector terminal assembly, which comprises a male terminal 10, a spring connection piece 20 and a female terminal 30. The male terminal 10 is provided with a plurality of mounting grooves 110 along the circumference of the outer side wall of the end portion. The spring connection piece 20 comprises a plurality of independent springs 210, which are inserted into the mounting grooves 110 to be electrically connected with the male terminal 10. The independent springs 210 are at least partially protruding from the outer side wall of the male terminal 10. The female terminal 30 is provided with an insertion groove 310 along one end portion. The end portion of the male terminal 10 with the spring connection piece 20 is inserted into the insertion groove 310. The independent springs 210 are adapted to abut against the groove wall of the insertion groove 310 to be electrically connected with the female terminal 30.

[0033] It should be noted that the spring connection piece 20 serves as a contact piece between the male terminal 10 and the female terminal 30, and is used to connect the male terminal 10 and the female terminal 30. The male terminal 10 is provided with a plurality of mounting grooves 110 along the axis direction of the outer side wall. The plurality of mounting grooves 110 are respectively used for clamping a plurality of independent springs 210. In this way, the independent springs 210 can be first installed on the male terminal 10 and then connected with the female terminal 30. The installation method is more convenient and controllable. Moreover, because the plurality of independent springs 210 are independently arranged instead of being integrally arranged, the contact area can be adjusted according to the number of independent springs 210. The independent springs 210 are also easier to replace, and the service life of the contact piece can be improved by regularly replacing the springs.

[0034] Specifically, because one end surface of the independent spring 210 abuts against the groove wall of the mounting groove 110 of the male terminal 10, the independent spring 210 and the male terminal 10 are in surface contact. In this way, the contact area between the independent spring 210 and the male terminal 10 is larger. Further, because the male terminal 10 is at least partially protruding from the outer side wall of the male terminal 10, when the male terminal 10 is connected with the female terminal 30, the end surface of the protruding portion of the independent spring 210 will also be in surface contact with the groove wall of the insertion groove 310 of the female terminal 30. In this way, the contact area between the independent spring 210 and the female terminal 30 is improved. Therefore, the arrangement of the independent spring 210 can simultaneously improve the contact area with the male terminal 10 and the female terminal 30, thereby improving the connection reliability of the contact piece.

[0035] Specifically refer to Figure 2 And Figure 3 For the mounting groove 110, the mounting groove 110 includes a first slot 1110 and a second slot 1120 which are in communication along the direction from the outer side wall of the male terminal 10 to the axis; the cross-sectional size of the first slot 1110 is smaller than that of the second slot 1120 to clamp the independent spring piece 210.

[0036] Because the cross-sectional size of the second slot 1120 is larger than that of the first slot 1110, when the independent spring piece 210 is inserted into the mounting groove 110, the second slot 1120 can form a clamping effect on the independent spring piece 210, avoiding the independent spring piece 210 from being separated from the mounting groove 110. Specifically, the setting of the mounting groove 110 limits the installation direction of the independent spring piece 210, so that the independent spring piece 210 enters the mounting groove 110 through the slot at the end of the male terminal 10, and cooperates with the shape of the second slot 1120 to avoid the independent spring piece 210 from being separated along the side of the first slot 1110.

[0037] For the independent spring piece 210, the independent spring piece 210 includes a protruding portion 2110 and a connecting portion 2120 connected with the protruding portion 2110; the connecting portion 2120 is clamped with the second slot 1120, and the protruding portion 2110 is arranged at least partially protruding from the outer side wall of the male terminal 10 through the first slot 1110.

[0038] That is, the installation mode of the independent spring piece 210 is to be inserted from the slot at the end of the male terminal 10 into the mounting groove 110, and to extend to a specified position along the length extension direction of the mounting groove 110, and because of the clamping effect of the second slot 1120, the independent spring piece 210 cannot be separated from the mounting groove 110 through the second slot 1120 to the side of the first slot 1110, thereby improving the installation stability of the independent spring piece 210.

[0039] In some embodiments of the present application, the cross-sectional shape of the mounting groove 110 is T-shaped, and the cross-sectional shape of the independent spring piece 210 corresponds to the cross-sectional shape of the mounting groove 110. In some other embodiments, the shape of the mounting groove 110 can also be "7" type, which is not limited here.

[0040] Because the cross-sectional shape of the mounting groove 110 is T-shaped, the cross-sectional shape of the corresponding independent spring piece 210 is also T-shaped. Thus, when the independent spring piece 210 is inserted into the mounting groove 110, the only way to take out the independent spring piece 210 is to take it out along the length extension direction of the mounting groove 110, and it will not fall to the outside at the side of the first slot 1110, thus limiting the position and installation mode of the independent spring piece 210.

[0041] Further, the mounting groove 110 extends along the axis direction of the male terminal 10, and the slot length of the mounting groove 110 is at least greater than the length of the independent spring piece 210.

[0042] Because the length of the installation groove 110 is greater than the length of the independent spring 210, the independent spring 210 can be completely inserted into the installation groove 110, thereby avoiding the independent spring 210 from partially protruding from the end of the male terminal 10, causing damage due to rigid impact when the male terminal 10 is connected with the female terminal 30, thereby playing a protective role for the independent spring 210.

[0043] Please continue to refer to Figure 2 In some embodiments of the present application, the spring connecting piece 20 further comprises an end cover 220, which is arranged on the end of the male terminal 10 and abuts against the independent spring 210.

[0044] The arrangement of the end cover 220 can prevent the independent spring 210 from falling near the end of the male terminal 10 through the installation groove 110, further limiting the position of the independent spring 210, so that the independent spring 210 cannot shake after installation, thereby ensuring the connection stability of the male terminal 10 and the female terminal 30.

[0045] Specifically, the end cover 220 is provided with a plurality of abutting blocks 2210, the cross-sectional dimension of the abutting block 2210 is at least smaller than the cross-sectional dimension of the installation groove 110, and the abutting block 2210 is at least partially inserted into the installation groove 110 to abut against the independent spring 210.

[0046] Preferably, the cross-sectional dimension of the abutting block 2210 is also selected to be T-shaped. After the independent spring 210 is installed, the end cover 220 is installed, thereby achieving clamping positioning of the independent spring 210, so that the independent spring 210 forms an integral whole with the male terminal 10, and then is connected with the female terminal 30, and because the independent spring 210 partially protrudes from the outer wall of the male terminal 10, when the male terminal 10 is connected with the female terminal 30, the independent spring 210 also abuts against the groove wall of the insertion groove 310 in the female terminal 30.

[0047] In this way, the independent spring 210 is in surface-to-surface contact with the male terminal 10 and the female terminal 30, thereby improving the contact reliability of the male terminal 10 and the female terminal 30.

[0048] That is, the installation of the independent spring 210 can achieve surface-to-surface contact between the male terminal 10 and the female terminal 30, thereby solving the technical problem of difficult disassembly and maintenance of the spring of the contact piece, and increasing the contact area of the contact piece with the male terminal 10 and the female terminal 30, thereby improving the contact reliability of the contact piece.

[0049] Further, the number of independent springs 210 can be adjusted according to the current size, thereby achieving adjustment of different contact areas.

[0050] In some embodiments of the present application, the abutting blocks 2210, the independent spring pieces 210 and the mounting grooves 110 are one-to-one corresponding.

[0051] In the present application, the number of the abutting blocks 2210, the independent spring pieces 210 and the mounting grooves 110 are respectively set to six, but in other embodiments, the number of the abutting blocks 2210, the independent spring pieces 210 and the mounting grooves 110 can also be respectively set to four, five or seven, etc., which is not limited herein, and different numbers of the independent spring pieces 210 can be selected according to the current size. For example, the male terminal 10 can be produced in different models that can be installed with different numbers of the independent spring pieces 210, so as to match the requirements of different current sizes.

[0052] In some embodiments of the present application, the end cover 220 is arc-shaped at the end away from the abutting blocks 2210 and the slot opening of the plug-in groove 310.

[0053] In this way, when the male terminal 10 and the female terminal 30 are connected, the arc-shaped arrangement can play a buffering and guiding role, avoiding rigid collision between the male terminal 10 and the female terminal 30, and prolonging the service life of the male terminal 10 and the female terminal 30.

[0054] The embodiments of the present application also propose a signal transmission system comprising the connector terminal assembly described above.

[0055] In the embodiments of the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature can be "above", "over" and "on" the second feature, which can be that the first feature is directly above or obliquely above the second feature, or only means that the horizontal height of the first feature is higher than that of the second feature. The first feature can be "below", "under" and "under" the second feature, which can be that the first feature is directly below or obliquely below the second feature, or only means that the horizontal height of the first feature is less than that of the second feature.
