It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are diagrammatically shown to simplify the drawings.

[0032] According to the overall technical concept of the present invention, there is provided a connection terminal. The connection terminal comprises a crimping portion 1 configured to be crimped onto a first conductor and a connection end portion 2 configured to be electrically connected to a second conductor and connected to the crimping portion 1 to form an integral part therewith.

Fig. 3 is an explanatory perspective view of a connection terminal according to an exemplary embodiment of the present invention, as viewed from one direction.

[0034] As shown in Figures 1 to 3, in the illustrated embodiment, the connection terminal includes a crimping portion 1 configured to be crimped to a first conductor (not shown), and for example, the crimping portion 1 may be crimped to an exposed conductor core wire of a cable.

[0035] 1 to 3, in the illustrated embodiment, the crimping part 1 includes a semi-cylindrical base part 10 and two joint parts 11, 12. The two joint parts 11, 12 extend continuously in the circumferential direction from both sides of the semi-cylindrical base part 10 and engage with each other to complete the cylindrical shape of the crimping part 1.

[0036] As shown in Figures 1 to 3, in the illustrated embodiment, buckle structures 11a, 12a are formed on the two joints 11, 12 to lock the two joints 11, 12 together and ensure that the two joints 11, 12 cannot be separated when the crimping portion 1 is crimped onto the first conductor.

[0037] As shown in Figures 1 to 3, in the illustrated embodiment, the buckle structures 11a, 12a include a buckle 11a and a snap slot 12a. The buckle 11a is formed in one seam 11 and protrudes circumferentially of the crimping portion 1 toward the other seam 12. The snap slot 12a is formed in the other seam 12. The shape and size of the snap slot 12a are complementary to the shape and size of the buckle 11a.

[0038] 1 to 3, in the illustrated embodiment, the buckle 11a and the snap slot 12a fit together in the radial direction of the crimping portion 1 and cannot be separated in any direction other than the radial direction. Therefore, when the crimping portion 1 is crimped onto the first conductor, the two joint portions 11, 12 do not separate.

[0039] 1 to 3, in the illustrated embodiment, buckle 11a has a base and an end, and the base of buckle 11a is narrower than the end of buckle 11a. Snap slot 12a has an opening and an interior that fit over the base and end of buckle 11a, and the opening of snap slot 12a is narrower than the interior of the snap slot.

[0040] As shown in Figures 1 to 3, in the illustrated embodiment, when buckle 11a and snap slot 12a are mated with each other, the large end of buckle 11a cannot be pulled out through the small opening of snap slot 12a, and buckle 11a and snap slot 12a cannot be separated in any direction other than the radial direction.

[0041] As shown in Figures 1 to 3, in the illustrated embodiment, the buckle 11a is dovetail-shaped with a narrow base and a wide end, and the snap slot 12a is dovetail-shaped with a narrow opening and a wide interior.

[0042] However, it should be noted that the present invention is not limited to the illustrated embodiment. For example, in another exemplary embodiment of the present invention, the base of the buckle 11a and the opening of the snap slot 12a are rectangular, and the end of the buckle 11a and the interior of the snap slot 12a are sector-shaped with a central angle greater than 180 degrees and less than 360 degrees. This Ω-shaped buckle 11a and snap slot 12a can also ensure a good fit.

[0043] Although not shown, in another exemplary embodiment of the present invention, the buckle 11a and the snap slot 12a may be curved hook-shaped, so that when the buckle 11a and the snap slot 12a are mated with each other, the buckle 11a and the snap slot 12a cannot be separated in any direction other than the radial direction. The hook-shaped buckle 11a and the snap slot 12a can also ensure a good fit.

[0044] As shown in FIGS. 1 to 3, in the illustrated embodiment, a pair of recesses 11b is also formed in one joint portion 11, and the pair of recesses 11b is located on both sides of the base of the buckle 11a.

[0047] As shown in FIGS. 1 to 3, in the illustrated embodiment, the seam S between the two seams 11, 12 includes two straight seams S1 and a curved seam located between the two straight seams S1. The two straight seams S1 are located at both axial ends of the crimping portion 1 and extend along the axial direction of the crimping portion 1. The curved seam is located between the two straight seams S1 and extends along a curved path. In the illustrated embodiment, the curved seam is defined by the outer contours of the mated buckle 11a and snap slot 12a and the mated recessed portion 11b and protruding portion 12b.

[0050] 1 to 3, in the illustrated embodiment, the longitudinal size of the connection hole 201 in the longitudinal direction of the connection terminal is larger than the lateral size of the connection hole 201 in the lateral direction of the connection terminal, so that the position of the fastener in the longitudinal direction can be adjusted, taking into account a certain manufacturing error in the size of the connection terminal.

[0051] 1 to 3, in the illustrated embodiment, the longitudinal axis of symmetry of the connection hole 201 of the connection end portion 2 and the central axis of the central through-hole 101 of the crimping portion 1 are on the same plane perpendicular to the lateral direction of the connection terminal, thereby shortening the length of the path through which the current flows.

[0052] 1 to 3, in the illustrated embodiment, the connection end 2 includes a lower plate 20 and an upper plate 21 overlapping the lower plate 20, and the thickness of the connection end 2 is greater than the thickness of the remaining part of the connection terminal.

[0054] As shown in Figures 1 to 3, in the illustrated embodiment, the connection terminal further includes a connection portion 3 connected between one end of the base portion 10 of the crimping portion 1 and one end of the lower plate 20 of the connection end portion 2.

[0055] 1 to 3, in the illustrated embodiment, the connection terminal is a terminal formed by integral stamping. For example, the connection terminal can be formed by stamping out a single metal plate.

[0056] FIG. 4 is an illustrative perspective view of a connection terminal according to another exemplary embodiment of the present invention.

[0057] The only difference between the connection terminal shown in FIG. 4 and the connection terminal shown in FIGS. 1 to 3 is the structure of the connection end portion 2.

[0058] 4, in the illustrated embodiment, the connection end 2 includes a single-layer plate, and the thickness of the connection end 2 is equal to the thickness of the remaining portion of the connection terminal. However, the present invention is not limited thereto. For example, in another exemplary embodiment of the present invention, the connection end 2 may include a thick single-layer plate, and the thickness of the connection end 2 may be greater than the thickness of the remaining portion of the connection terminal.

[0059] Although not shown, another exemplary embodiment of the present invention also discloses a cable assembly including a cable and the above-mentioned connection terminal.
