Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] The following reference Figures 1 to 12 This application describes a connection terminal assembly according to some embodiments.

[0025] See Figures 1 to 12As shown, an embodiment of this application provides a connection terminal assembly, including: a first terminal 1, a second terminal 2, and a locking member 3; wherein, the second terminal 2 is inserted into the mounting cavity 13 of the first terminal 1; the first terminal 1 has a first mounting through hole 11 penetrating at least one side therethrough and a clearance through hole 12 disposed on the side of the first mounting through hole 11, and the second terminal 2 has a second mounting through hole 21 penetrating at least one side therethrough and a countersunk platform 22 disposed around the outer periphery of the second mounting through hole 21; The locking member 3 includes a body 31 and a limiting part 32 disposed on the side of the body 31. The body 31 is installed in the first mounting through hole 11 and the second mounting through hole 21 and can rotate. The limiting part 32 can enter the limiting space formed by the inner wall of the recessed platform 22 and the first terminal 1 through the clearance through hole 12. The limiting part 32 can rotate with the body 31 to be staggered with the clearance through hole 12, so that the limiting part 32 is restricted between the inner wall of the recessed platform 22 and the first terminal 1.

[0026] As can be seen from the structure described above, when using the connection terminal assembly provided in this application, the second terminal 2 and the first terminal 1 are first inserted together. Then, the body 31 of the locking member 3 is aligned with the first mounting through hole 11, and the limiting part 32 of the locking member 3 is aligned with the clearance through hole 12. The entire locking member 3 is then inserted into the first terminal 1 and the second terminal 2. When the limiting part 32 abuts against the countersunk platform 22, the locking member 3 is rotated so that the limiting part 32 of the locking member 3 is staggered with the clearance through hole 12, thereby preventing the locking member 3 from being removed and locking the first terminal 1 and the second terminal 2 to prevent them from separating.

[0027] Furthermore, when it is necessary to disassemble the first terminal 1 and the second terminal 2, it is only necessary to rotate the locking member 3 so that the body 31 of the locking member 3 is aligned with the first mounting through hole 11 and the limiting part 32 of the locking member 3 is aligned with the clearance through hole 12. Then, the entire locking member 3 is pulled out from the first terminal 1 and the second terminal 2, and then the first terminal 1 and the second terminal 2 are pulled apart in opposite directions. The operation is simple, convenient, time-saving and labor-saving, and can be used for maintenance of the first terminal 1 and the second terminal 2.

[0028] Of course, the usage steps are not limited to those described above, and adjustments can be made as needed. In addition, it should be noted that the connection terminal assembly provided in this application can be XT series terminals, but it is not limited to these and can also be other types of terminals.

[0029] It should be noted that one of the first terminal 1 and the second terminal 2 can be a male terminal, and the other can be a female terminal, depending on the actual needs.

[0030] In this embodiment, preferably, as follows: Figures 2 to 4As shown, the first mounting through hole 11 extends through the opposite sides of the first terminal 1. That is, the first mounting through hole 11 extends through the first side wall 14 and the second side wall 15 of the first terminal 1. In other words, the first mounting through hole 11 is provided on both the first side wall 14 and the second side wall 15 of the first terminal 1. This allows the body 31 of the locking member 3 to extend from the first side wall 14 to the second side wall 15 and simultaneously cooperate with the first side wall 14 and the second side wall 15, increasing the area of ​​the cooperation area and improving the overall locking effect on the first terminal 1.

[0031] Of course, it is not limited to this. The first mounting through hole 11 may also extend only through one side of the first terminal 1, that is, the first mounting through hole 11 may be provided only on the first side wall 14 or the second side wall 15, depending on the actual needs. In this embodiment, preferably, as follows: Figures 2 to 4 As shown, the first mounting through hole 11 is set along the insertion direction perpendicular to the insertion direction of the second terminal 2 and the first terminal 1, i.e., insertion direction a, to meet assembly requirements and prevent the locking component 3 from being installed at an angle, thus avoiding problems such as jamming. Of course, it is not limited to this; the first mounting through hole 11 can also be set at an angle relative to the height direction of the first terminal 1, depending on the actual needs. In this embodiment, preferably, as follows: Figure 8 and Figure 9 As shown, the second mounting through hole 21 extends through the opposite sides of the second terminal 2. That is, the second mounting through hole 21 extends through the third side wall 23 and the fourth side wall 24 of the second terminal 2. In other words, the aforementioned second mounting through hole 21 is provided on both the third side wall 23 and the fourth side wall 24 of the second terminal 2. This allows the body 31 of the locking member 3 to extend from the third side wall 23 to the fourth side wall 24 and simultaneously cooperate with the third side wall 23 and the fourth side wall 24, increasing the area of ​​the cooperation area and improving the overall locking effect on the second terminal 2.

[0032] Of course, it is not limited to this. The second mounting through hole 21 can also be provided only on one side of the second terminal 2, that is, the second mounting through hole 21 can be provided only on the third side wall 23 or the fourth side wall 24, depending on the actual needs. Furthermore, preferably, the length direction of the first terminal 1 and the second terminal 2 is the same as the insertion direction a, but of course, it is not limited to this.

[0033] In this embodiment, preferably, as follows: Figure 8 and Figure 9As shown, the second mounting through hole 21 is set along the insertion direction perpendicular to the insertion direction of the second terminal 2 and the first terminal 1, i.e., insertion direction a, to meet assembly requirements and prevent the locking component 3 from being installed at an angle, thus avoiding problems such as jamming. Of course, it is not limited to this; the second mounting through hole 21 can also be set at an angle relative to the height direction of the first terminal 1, depending on the actual needs. In this embodiment, preferably, as follows: Figure 1 , Figure 6 and Figure 12 As shown, limiting portions 32 are formed on both opposite sides of the main body 31. Correspondingly, avoidance through holes 12 need to be provided on both opposite sides of the first mounting through hole 11, and they correspond one-to-one with the limiting portions 32 on both sides. As can be seen from the structure described above, providing limiting parts 32 on both sides of the main body 31 helps to improve the limiting effect and enhance the locking effect on the first terminal 1 and the second terminal 2. Of course, limiting parts 32 can also be provided on only one side of the main body 31, depending on the actual needs.

[0034] Furthermore, preferably, the body 31 and the limiting part 32 are an integral structure, which has high overall strength and is not easily damaged.

[0035] In this embodiment, preferably, as follows: Figure 1 As shown, along the insertion direction perpendicular to the second terminal 2 and the first terminal 1, i.e., insertion direction a, the limiting part 32 can be restricted between the recessed platform 22 and the inner wall of the first terminal 1 to meet the assembly and use requirements, and of course, it is not limited to this.

[0036] In this embodiment, preferably, as follows: Figure 12 As shown, a recess 33 is formed at one end of the body 31 exposed above the first mounting through hole 11, which allows the locking component 3 to be rotated with tools such as screwdrivers, thereby improving the ease of operation. Of course, it is not limited to this; the shape of the recess 33 can be set arbitrarily, such as a cross-shaped groove, etc., depending on the actual needs.

[0037] In addition, it should be noted that: instead of opening the groove 33 on the body 31 of the locking member 3, the body 31 can be lengthened so that part of the structure of the body 31 extends out of the first terminal 1. In this way, the body 31 of the locking member 3 can be turned by hand, which is also convenient to operate. In this embodiment, preferably, as follows: Figure 1 As shown, along the insertion direction of the second terminal 2 and the first terminal 1, i.e., insertion direction a, the first terminal 1 has two first mounting through holes 11 arranged in sequence at intervals; along the insertion direction of the second terminal 2 and the first terminal 1, i.e., insertion direction a, the second terminal 2 has two second mounting through holes 21 arranged in sequence at intervals. The two first mounting through holes 11 and the two second mounting through holes 21 correspond one-to-one, and each set of first mounting through holes 11 and second mounting through holes 21 is equipped with a locking member 3. As can be seen from the structure described above, this application is equipped with two sets of mounting through holes and two locking components 3, which helps to improve the locking effect on the first terminal 1 and the second terminal 2.

[0038] It should be noted that: it is not limited to the above, a set of mounting through holes and a matching locking component 3 can also be set. Of course, it is not limited to this, and more than two sets of mounting through holes and two matching locking components 3 can be set, such as three sets of mounting through holes and three matching locking components 3. The specific selection depends on the actual needs.

[0039] Furthermore, preferably, the two recessed platforms 22 are connected along the insertion direction of the second terminal 2 and the first terminal 1, i.e., insertion direction a, and the recessed platform 22 near the edge of the second terminal 2 passes through the edge of the second terminal 2, which facilitates processing, manufacturing and installation. Of course, it is not limited to this, the two recessed platforms 22 may not be connected, depending on the actual needs. In this embodiment, preferably, as follows: Figure 8 As shown, the recessed platform 22 includes a circular recessed platform 221 and a square recessed platform 222 that are connected to each other. The square recessed platform 222 is disposed on the side of the circular recessed platform 221. The circular recessed platform 221 is disposed on the outer periphery of the first mounting through hole 11, and the square recessed platform 222 is disposed on the side of the avoidance through hole 12.

[0040] As can be seen from the structure described above, both the square recessed platform 222 and the circular recessed platform 221 are for supporting and limiting the limiting part 32. When the limiting part 32 passes through the clearance through hole 12 and falls, the square recessed platform 222 will first contact the limiting part 32, indicating that it is installed in place. Then, the main body 31 will rotate, thereby driving the limiting part 32 to rotate, so that the limiting part 32 contacts the circular recessed platform 221, and the circular platform supports and limits the limiting part 32.

[0041] Of course, the shape of the recessed platform 22 is not limited to this. It can also be a circular recessed platform 221 or a directional recessed platform 22, or a recessed platform 22 of other shapes, etc., depending on the actual needs.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
