[0028] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the illustrated embodiments are not intended to limit the present utility model.

[0029] The present utility model provides a male connector structure for plugging and clamping into a corresponding female connector A. Please refer to Figures 1 to 4 As shown, in the first embodiment of the present utility model, the male connector structure includes a tongue plate 10 and a latching kit 20.

[0030] The tongue plate 10 is made of insulating material. In this embodiment, the tongue plate 10 is integrally formed by plastic injection, but the present utility model is not limited thereto. The tongue plate 10 is in a flat plate shape, and thus has a relative first plane 101 and a second plane 102, a pair of relative side planes 103, and an end face 104. Referring to Figures 1 to 4 the respective drawings, in this embodiment, the first plane 101 is located on the top surface of the tongue plate 10, the second plane 102 is located on the bottom surface of the tongue plate 10, the side planes 103 are located on the left and right sides of the tongue plate 10, and the end face 104 is located at the front end of the tongue plate 10, but the present utility model is not limited to the directions shown in the drawings.

[0031] The latching kit 20 is made of metal with good electrical conductivity. The latching kit 20 mainly includes a fixing sleeve 21 and a pair of leaf spring groups 22. The fixing sleeve 21 is sleeved and clamped on the tongue plate 10. Specifically, the tongue plate 10 is respectively formed with a card slot 1031 on each side plane 103, and the opposite sides (left and right sides) of the fixing sleeve 21 are sleeved on the tongue plate 10 and clamped in the respective card slots 1031. In this embodiment, after the fixing sleeve 21 is sleeved and clamped on the tongue plate 10, it can also be further fixed by welding, bonding, fusing, etc., but the present utility model does not limit this much. Each leaf spring group 22 is connected to the fixing sleeve 21, and each leaf spring group 22 is respectively arranged on the upper and lower sides of the tongue plate 10 corresponding to the first plane 101 and the second plane 102. Each leaf spring group 22 includes a plurality of elastic arms 221 arranged at intervals and in parallel. Each elastic arm 221 extends from the fixing sleeve 21 and arches away from the tongue plate 10.

[0032] Refer back to Figure 3 and Figure 4 As shown, when the male terminal connector structure is inserted into the female terminal connector A, the arched portions of the elastic arms 221 are clamped and fixed to the inner wall of the female terminal connector A, so as to be able to form an electrical connection and a clamping and positioning effect with the female terminal connector A. Thus, by arranging the connection kit 20 on the male terminal connector, the overall structure and production cost of the female terminal connector A can be greatly simplified; and since the connection kit 20 is easy to manufacture, the number of elastic arms 221 can be greatly increased to increase the number of contact points with the female terminal connector A, thereby effectively improving the efficiency, stability and service life of current transmission.

[0033] Further illustrate, each elastic arm 221 arches into an arc shape, a semi-circular shape or an inverted V shape. In this embodiment, each elastic arm 221 arches into an arc shape, but the present invention is not limited thereto, and the arched shape of each elastic arm 221 should be adjustable according to different requirements. Specifically, each elastic arm 221 includes a connecting section 2211, an arched section 2212 and an abutting section 2213. In each elastic arm 221, the connecting section 2211 is connected to the fixed sleeve 21, and the two ends of the arched section 2212 are respectively connected to the connecting section 2211 and the abutting section 2213, and the abutting section 2213 abuts against the corresponding first plane 101 or the second plane 102. In this embodiment, the connecting section 2211 extends obliquely from the fixed sleeve 21 towards the tongue plate 10, so that a part of the connecting section 2211 abuts against the corresponding first plane 101 or the second plane 102, and the arching height of the arched section 2212 can be increased, but the present invention is not limited thereto. More specifically, each elastic arm 221 extends obliquely from the fixed sleeve 21 towards the tongue plate 10 through the connecting section 2211, then arches away from the tongue plate 10 through the arched section 2212, and finally abuts against the corresponding first plane 101 or the second plane 102 by means of the abutting section 2213.

[0034] Refer back to Figure 1 、 Figure 2 and Figure 4As shown in the figure, the fixed sleeve 21 in this embodiment includes a first plate body 211, a second plate body 212, a third plate body 213, a first joint plate 214, and a second joint plate 215 which are integrally connected. The first plate body 211 and the second plate body 212 are arranged parallel to each other relatively, and the first plate body 211 and the second plate body 212 are respectively attached to the first plane 101 and the second plane 102. The third plate body 213 is connected to the same side of the first plate body 211 and the second plate body 212, that is, the third plate body 213 is attached to the side plane 103 on the right side of the tongue plate 10 in the figure. The first joint plate 214 is connected to the other side of the first plate body 211 and extends towards the second plate body 212, and the second joint plate 215 is connected to the other side of the second plate body 212 and extends towards the first plate body 211, that is, both the first joint plate 214 and the second joint plate 215 are attached to the side plane 103 on the left side of the tongue plate 10 in the figure. Specifically, the fixed sleeve 21 is formed into a sleeve-shaped structure of the first plate body 211, the second plate body 212, the third plate body 213, the first joint plate 214, and the second joint plate 215 through multiple (at least four times) bends. Also, the first joint plate 214 has at least one limit bump 216, and the second joint plate 215 has at least one positioning groove 217. The limit bump 216 is clamped in the positioning groove 217, so that the first joint plate 214 and the second joint plate 215 can be positioned relative to each other and will not separate, and further enable the fixed sleeve 21 to maintain the sleeve-shaped structure. In this embodiment, the number of both the limit bump 216 and the positioning groove 217 is two, but the present utility model is not limited thereto.

[0035] Also, the fixed sleeve 21 in this embodiment has a pair of through slots 218. Each through slot 218 is respectively arranged corresponding to the first plane 101 and a second plane 102, that is, each through slot 218 is respectively arranged corresponding to the first plane 101 and the second plane 102 of the tongue plate 10. Each leaf spring group 22 is respectively located in each through slot 218. In this embodiment, each leaf spring group 22 is connected to the side of the fixed sleeve 21 adjacent to the end of the tongue plate 10, but the present utility model is not limited thereto. Specifically, in this embodiment, each elastic arm 221 of each leaf spring group 22 extends obliquely from the edge of the through slot 218 of the fixed sleeve 21 adjacent to the end of the tongue plate 10 towards the center of the through slot 218 and the tongue plate 10, that is, each elastic arm 221 extends in the direction away from the end of the tongue plate 10 as a whole, and the connecting section 2211, the arched section 2212, and the abutting section 2213 of each elastic arm 221 are all within the range of the through slot 218. Also, there is a distance between the end of the abutting section 2213 of each elastic arm 221 and the edge of the through slot 218. Therefore, when the male end connector structure is inserted into the female end connector A, there is space for each elastic arm 221 to deform without interfering with the fixed sleeve 21.

[0036] Please then refer to Figures 5 to 8As shown, the second embodiment of the present utility model is mainly different from the first embodiment in the form and structure of the overlapping kit 20, and the specific details are described as follows:

[0037] In this embodiment, the overlapping kit 20 further includes a connecting plate 23, and the fixed sleeve 21 does not have a pair of through slots 218 in the first embodiment. The opposite sides (upper and lower sides) of the connecting plate 23 are respectively connected to the abutting segments 2213 of each leaf spring group 22, so that the connecting plate 23 is located at the end face 104 of the front side of the tongue plate 10. Therefore, each leaf spring group 22 in this embodiment is connected to the side of the fixed sleeve 21, which is different from that in the first embodiment where each leaf spring group 22 is fixed in the through slots 218 of the fixed sleeve 21.

[0038] Furthermore, the fixed sleeve 21 has at least one fastening hole 219, and the tongue plate 10 has at least one buckle 105. The buckle 105 is fastened in the fastening hole 219, so that the overlapping kit 20 can be fixed on the tongue plate 10 and cannot be easily detached. In this case, the technical means of further fixing the overlapping kit 20 and the tongue plate 10 by welding, bonding, fusing, etc. in the first embodiment can be omitted. However, the second embodiment of the present utility model does not exclude further strengthening the overlapping kit 20 and the tongue plate 10 by welding, bonding, fusing, etc. In this embodiment, the fixed sleeve 21 has a plurality of fastening holes 219, and the tongue plate 10 has a pair of buckles 105. Each buckle 105 is respectively arranged on the opposite sides of the tongue plate 10 and fastened in each fastening hole 219, so as to achieve a good buckling effect of the buckle 105. Specifically, each buckle 105 in this embodiment is respectively arranged on the first plane 101 and the second plane 102, but in other embodiments, each buckle 105 can also be respectively arranged on each side plane 103.

[0039] In this embodiment, the fixed sleeve 21 includes a first plate body 211, a second plate body 212 and a pair of extension plates 210. The first plate body 211 and the second plate body 212 are arranged parallel to each other relatively, and the first plate body 211 and the second plate body 212 are respectively attached to the first plane 101 and the second plane 102. The opposite sides (left and right sides) of the first plate body 211 respectively have a limiting bump 216 extending towards the second plate body 212. Each extension plate 210 extends from the opposite sides (left and right sides) of the second plate body 212 towards the first plate body 211, so as to respectively attach to the side planes 103 of the tongue plate 10. Each extension plate 210 has a positioning groove 217. Each limiting bump 216 is respectively clamped in each positioning groove 217, so that the first plate body 211 and each extension plate 210 can be positioned relative to each other and will not separate, and further enable the fixed sleeve 21 to maintain a sleeve-like structure. It should be noted that the fixed sleeve 21 in this embodiment is different from that in the first embodiment which is integrally connected. Since the lapping kit 20 in this embodiment mainly connects the respective leaf spring groups 22 on the upper and lower sides to the corresponding first plate body 211, second plate body 212 and each extension plate 210 through the connecting plate 23, the fixed sleeve 21 forms a sleeve-like structure by being assembled up and down.

[0040] For the male terminal connector structure of the present utility model, by sleeving and fixing the lapping kit 20 on the tongue plate 10, and each leaf spring group 22 of the lapping kit 20 respectively has a plurality of arched elastic arms 221. Therefore, when the male terminal connector structure is inserted into the female terminal connector A, the arched portions of each elastic arm 221 can be clamped and fixed to the inner wall of the female terminal connector A to form a lap joint, thereby greatly simplifying the overall structure and production cost of the female terminal connector A, and increasing the number of elastic arms 221 to increase the number of contact points with the female terminal connector A in lap joint, and further effectively improving the efficiency, stability and service life of current transmission.

[0041] The above-described embodiments are only preferred embodiments given to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present utility model are all within the protection scope of the present utility model.
