[0025] Although the present disclosure will be fully described with reference to the drawings containing the preferred embodiments of the present disclosure, it should be understood before this description that those of ordinary skill in the art may modify the present disclosure described herein while achieving the technical effects of the present disclosure. Therefore, it should be understood that the above description is a broad disclosure to those of ordinary skill in the art, and its content is not intended to limit the exemplary embodiments described in the present disclosure.
[0026] In addition, in the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is obvious that one or more embodiments may be implemented without these specific details. In other cases, well-known structures and devices are illustrated in a schematic manner to simplify the drawings.
[0027] According to the general inventive concept of the present disclosure, there is provided a conductive terminal, the conductive terminal including a terminal body and a connector, a plug-in cylinder being formed at a first end of the connector, a second end of the connector opposite to the first end being mounted on the terminal body, the plug-in cylinder forming a plug-in cavity for inserting a mating terminal, a plurality of split grooves being formed on a side wall of the plug-in cylinder, each split groove extending from an open end of the plug-in cylinder to the other end of the plug-in cylinder opposite to the open end, wherein the connector is made by a cold heading or cold forging process.
[0028] According to another general inventive concept of the present disclosure, there is provided a connector, the connector including a connector housing and a conductive terminal mounted in the connector housing, wherein the conductive terminal is the conductive terminal according to the embodiment of the present disclosure.
[0029] Figures 1 to 2 A conductive terminal according to an exemplary embodiment of the present disclosure is shown. As Figures 1 to 2As shown, the conductive terminal 100 includes a generally plate-shaped terminal body 10 and a generally cylindrical plug-in member 20. A plug-in cylinder 21 is formed at the first end of the plug-in member 20, and the second end of the plug-in member 20 opposite to the first end is mounted on the terminal body 10. The plug-in member 20 is made by cold heading or cold forging process. The plug-in cylinder 21 forms a plug-in cavity 27 for inserting a mating terminal (not shown). A plurality of split grooves 22 are provided on the side wall of the plug-in cylinder 21. Each split groove 22 extends from the open end of the plug-in cylinder 21 to the other end of the plug-in cylinder 21 opposite to the open end. The open end of the plug-in cylinder 21 is divided into a plurality of contact pieces 23 by the plurality of split grooves 22. When the mating terminal is inserted into the plug-in cavity 27 of the conductive terminal 100, the contact piece 23 contacts the mating terminal located in the plug-in cavity 26. Compared with the traditional machining manufacturing process, according to an exemplary embodiment of the present disclosure, the conductive terminal 100 adopts a two-component structure, that is, the terminal body 10 and the plug-in member 20 are two separate components, and the plug-in member 21 is manufactured by cold heading or cold forging process. This can simplify the processing process and can produce a larger number (for example, more than 8) of contact pieces, thereby increasing the number of contact points contacting the mating terminal, improving the resistance stability and reducing the cost. In addition, by manufacturing the plug-in member 20 by cold heading or cold forging process, the contact piece 23 of the plug-in member 20 can be made smooth and burr-free, so that the insertion force can be reduced when the mating terminal is inserted into the plug-in cylinder 27 of the conductive terminal 100.
[0030] According to an exemplary embodiment of the present disclosure, as Figure 1 and Figure 2 shown, the second end of the plug-in member 20 is connected to the terminal body 10 by welding. However, in some other embodiments of the present disclosure, the second end of the plug-in member 20 can also be threadedly connected to the terminal body 10. Specifically, for example, an external thread is provided at the second end of the plug-in member 20, and a mounting hole is formed on the terminal body 10. The mounting hole has an internal thread. By the cooperation of the external thread of the plug-in member 20 and the internal thread formed on the mounting hole in the terminal body 10, the plug-in member 20 can be mounted on the terminal body 10. It should be noted that in some other embodiments of the present disclosure, the second end of the plug-in member 20 can also be connected to the terminal body 10 in other ways.
[0031] According to an exemplary embodiment of the present disclosure, as Figure 1 and Figure 2 shown, the terminal body 10 is made of aluminum, which can further reduce the cost compared with the terminal body made of copper in the prior art. Of course, the terminal body 10 can also be made of copper or other suitable materials known in the art.
[0032] According to an exemplary embodiment of the present disclosure, as Figure 1 、 Figure 2 and Figure 3As shown, the number of the split grooves 22 is 16, and the multiple split grooves 22 are evenly distributed along the circumferential direction of the insertion cylinder 21 to increase the holding force, thereby improving the connection reliability between the conductive terminal 100 and the mating terminal, and making the insertion part 20 be uniformly stressed in the circumferential direction as a whole. It should be noted that although in Figure 1 , Figure 2 and Figure 3 the shown embodiments, 16 split grooves are shown, however, in some other embodiments of the present disclosure, the number of the split grooves 22 may also be other values, such as 8, 12, 18, 24, etc. The specific number of the split grooves 22 should be designed according to specific situations, and the present disclosure does not limit this. In addition, although in Figure 1 , Figure 2 and Figure 3 the shown embodiments, the 16 split grooves 22 are evenly distributed along the circumferential direction of the insertion cylinder 21, however, in some other embodiments of the present disclosure, the multiple split grooves 22 may also be unevenly distributed along the circumferential direction of the insertion cylinder 21.
[0033] According to an exemplary embodiment of the present disclosure, as shown in Figure 1 , Figure 2 and Figure 3 , a part of the outer wall of the insertion cylinder 21 near the opening end forms an annular groove 24, and a fixing ring 30 is embedded in the annular groove 24. When the mating terminal is inserted into the insertion cavity 27 of the conductive terminal 100, the fixing ring 30 can provide a certain holding force for the conductive terminal 100 to maintain the stable contact between the conductive terminal 100 and the mating terminal.
[0034] According to another exemplary embodiment of the present disclosure, as shown in Figure 1 , Figure 2 and Figure 3 , a locking groove 25 for fixing the conductive terminal 100 is formed on the outer wall of the insertion part 20, and the locking groove 25 is arranged between the insertion cylinder 21 and the second end of the insertion part 20. The locking groove 25 can cooperate with a locking boss on a connector housing (not shown) to form a locking structure for locking the conductive terminal 100 and the connector housing. It should be noted that in some other embodiments of the present disclosure, the locking groove 25 may also be replaced by a locking boss, and correspondingly, the connector housing forms a locking groove cooperating with the locking boss to form a locking structure for locking the conductive terminal 100 and the connector housing.
[0035] According to another exemplary embodiment of the present disclosure, as shown in Figure 1 , Figure 2 and Figure 3 , an annular accommodating part 26 for accommodating a sealing ring is formed on the outer wall of the insertion part 20, and the annular accommodating part 26 is located between the locking groove 25 and the second end of the insertion part 20.
[0036] According to an exemplary embodiment of the present disclosure, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a threaded hole 11 is formed on the terminal body, and the conductive terminal 100 further includes a fixing member 40 threadedly connected to the threaded hole 11. The fixing member 40 is configured to fix a conductive sheet (not shown) electrically connected to a cable on the terminal body 10. Specifically, the fixing member 40 includes a head 41 and a connecting portion 42 connected to the head 41. The connecting portion 42 is configured to be threadedly connected to the threaded hole 11 on the terminal body 10, and the size of the head 41 is larger than the size of the through hole formed in the conductive sheet. During assembly, the conductor of the cable can be welded to the conductive sheet, and the connecting portion 42 of the fixing member 40 is passed through the through hole in the conductive sheet and threadedly connected to the threaded hole 11 on the terminal body 10, thereby fixing the conductive sheet on the terminal body 10 to achieve electrical connection between the conductive terminal 100 and the cable.
[0037] In another exemplary embodiment of the present disclosure, as Figure 6 shown, a welding portion 12 may also be provided on the terminal body 10, and the conductor of the cable (not shown) for electrically connecting to the conductive terminal 100 is welded at the welding portion 12 to achieve electrical connection between the conductive terminal 100 and the cable.
[0038] According to another aspect of the present disclosure, a connector is further provided. The connector includes a connector housing and a conductive terminal installed in the connector housing. Among them, the conductive terminal adopts the conductive terminal 100 according to the embodiments of the present disclosure.
[0039] The conductive terminal of the connector according to various embodiments of the present disclosure adopts a two-component structure, that is, the terminal body and the plug-in member are two separate components. Among them, the plug-in member is manufactured by cold heading or cold forging process. Compared with the traditional machining manufacturing process, this can simplify the processing process and increase the number of split grooves (for example, more than 8), thereby increasing the number of contact points contacting the mating terminal, improving the resistance stability and reducing the cost. In addition, by manufacturing the plug-in member by cold heading or cold forging process, the contact piece of the plug-in member can be smooth and burr-free, so the insertion force when inserting the mating terminal into the insertion barrel of the conductive terminal can be reduced.
