[0020] In the present invention, the directional terms such as "upper side" and "lower side" are all represented according to the directional diagrams in the drawings of the specification.

[0021] Reference Figures 1 to 8 The utility model is implemented as follows: a power and signal connector female end, including an insulating seat 1, a power terminal 2 assembled and connected to the insulating seat 1, and a signal module 3 assembled and connected to the insulating seat 1, the insulating seat 1 is provided with a plurality of power installation holes 11 and signal installation holes 12 communicating with the slot, the power terminal 2 is installed in the power installation hole 11, the signal module 3 is installed in the signal installation hole 12, the signal module 3 is buckled with the signal installation hole 12 and partially extends out of the outside of the insulating seat 1 to form a positioning grid 31.

[0022] In the present invention, the signal module 3 is produced by integral injection molding, which avoids the possibility of poor stability of the terminal due to the insertion force, thereby extending the service life of the present invention. The positioning grid 31 is formed by the signal module 3 being installed into the signal installation hole 12, which not only limits the position of the signal module 3 entering the insulating seat 1, but also provides positioning for the connector when the present invention is mated with the female end of the connector, avoiding damage caused by excessive mating when the female end of the connector is mated, thereby extending the service life of the present invention.

[0023] On the basis of the above embodiment, as a further preference, the power supply installation hole 11 includes a power supply installation main hole 111 that passes through the insulating seat 1, and the two sides of the power supply installation main hole 111 are provided with a power supply installation groove 112, a heat dissipation groove 113 and a heat dissipation hole 114, the heat dissipation groove 113 and the heat dissipation hole 114 are arranged between the power supply installation groove 112 and communicate with the power supply installation groove 112, and the power supply installation groove 112 includes a power supply installation upper entry groove 1121 and a power supply installation positioning blind groove located at the lower side of the power supply installation upper entry groove 1121 1122, the width of the power supply installation upper slot 1121 is greater than the width of the power supply installation positioning blind slot 1122, a chamfer 11221 is provided at the entrance of the power supply installation positioning blind slot 1122 on one side facing the heat dissipation hole 114, the other side of the power supply installation positioning blind slot 1122 is flush with the same direction side of the power supply installation upper slot 1121, a heat dissipation slot 113 is provided on one side of the power supply installation upper slot 1121, the heat dissipation hole 114 is arranged at one end of the positioning blind slot, and two heat dissipation holes 114 are arranged, and the two heat dissipation holes 114 are communicated.

[0024] The power terminal 2 includes a power terminal main body 21, a power terminal connecting part 22 fixedly connected to the power terminal main body 21, and a power terminal plug-in part 23. The power terminal main body 21 and the power terminal plug-in part 23 have the same thickness. The power terminal plug-in part 23 is parallel to the power terminal main body 21. A smooth inclined connection part 24 is provided between the power terminal plug-in part 23 and the power terminal main body 21. The power terminal plug-in part 23 and the power terminal main body 21 are both set to be quadrilaterals. The power terminal plug-in part 23 is confined in the power supply installation positioning blind groove 1122.

[0025] Different from other female connectors that use elastic structures, the plug-in portion of the power terminal 2 of the utility model uses a rigid structure. The power plug-in portion 23 is limited to the power installation positioning blind groove 1122, and has strong installation firmness, avoiding the influence of external forces on the firmness of the power plug-in portion during mating. The setting of the heat dissipation groove 113 helps dissipate heat, and the heat dissipation holes 114 are set on both sides of the power terminal plug-in portion 23 for easy heat dissipation, and the heat dissipation holes 114 are connected and connected to the power installation groove 112, thereby improving the heat dissipation efficiency.

[0026] Since the width of the power supply installation upper slot 1121 is greater than the width of the power supply installation positioning blind slot 1122, the other side of the power supply installation positioning blind slot 1122 is flush with the same direction side of the power supply installation upper slot 1121, the power terminal insertion portion 23 is parallel to the power terminal main body 21, and a smooth inclined connection 24 is provided between the power terminal insertion portion 23 and the power terminal main body 21. When the power terminal 2 is installed into the power supply installation slot 112, the power terminal insertion portion 23 enters the power supply installation positioning blind slot 1122, and the power terminal main body 21 enters the power supply installation upper slot 1121. A gap 11212 is formed between the power terminal main body 21 and the side wall of the power supply installation upper slot 1121, which is convenient for the heat dissipation of the utility model and improves the heat dissipation efficiency.

[0027] On the basis of the above embodiment, as a further preference, the signal installation hole 12 includes a signal installation main hole 121, a signal installation small hole 122 which is connected to the signal installation main hole 121 and linearly arranged at the bottom of the signal installation main hole 121, and a through hole 123 which is connected to the bottom of the signal installation small hole 122 and passes through the insulating seat 1 to communicate with the outside world. A buckle window 1231 and a through hole 2 1232 are provided on the side of the signal installation main hole 121. The center line of the through hole 123 in the direction toward the through hole 2 1232 is offset from the center line of the signal installation small hole 122, and the signal module 3 extends out of the through hole 2 1232.

[0028] The signal module 3 includes a signal plastic seat 32 and a signal terminal 33 fixed in the signal plastic seat 32. The signal plastic seat 32 is provided with a buckle position 321. The signal terminal 33 includes a signal terminal body 331, a signal terminal connecting portion 332 fixedly connected to one end of the signal terminal body 331, and a signal terminal plug-in portion 333 fixedly connected to the other end of the signal terminal body 331. The signal terminal connecting portion 332 forms an angle of 90° with the signal terminal plug-in portion 333. The signal terminal body 331 is embedded in the signal plastic seat 32. The signal terminal pair plug-in portion 333 extends out of the signal plastic seat 32, and the signal terminal pair plug-in portion 333 includes an elastic arm 3331 and an elastic portion 3332. The elastic arm 3331 is provided with a second heat dissipation groove 3333, and the elastic portion 3332 is provided with a protrusion 3334 in the direction of the center line of the second through hole 1232. Since the center line of the through hole 123 in the direction toward the second through hole 1232 is offset from the center line of the signal mounting hole 122, a large gap 3335 exists between the elastic arm 3331 in the signal mounting hole 122 and the side wall of the signal mounting hole 122.

[0029] The signal plastic seat 32 is assembled into the signal installation hole 12, and the buckle position 321 is buckled with the buckle window 1231, so that the signal module 3 can be stably assembled in the signal installation hole 12, thereby avoiding the problem of poor stability of the signal terminal 33 in the signal plastic seat due to excessive insertion force during the male and female insertion process. The signal plastic seat 32 is installed into the signal installation hole 122, and the signal terminal insertion portion 333 extends into the signal installation hole 122. The elastic portion 3332 is provided with a protrusion 3334 facing the center line direction of the second through hole 1232. When the present invention is plugged into the male end of the connector, the signal terminal 33 of the male end of the connector enters the signal installation hole 122 from the second through hole 1232 and is pressed and contacted with the protrusion 3334, pressing the elastic arm 3331 toward the side wall of the signal installation hole 122. The gap 3335 between the elastic arm 3331 and the signal installation hole 122 provides a buffer space for the deformation direction of the elastic arm 3331 when being pressed and contacted. At the same time, the gap 3335 between the elastic arm 3331 and the signal installation hole 122 also improves the heat dissipation efficiency of the present invention.

[0030] On the basis of the above embodiments, as a further preference, the insulating seat 1 includes a load-bearing end 14 and a plug-in end 15 fixedly connected to one end of the load-bearing end 14, and positioning columns 151 are provided at both ends of the plug-in end 15. The cross-section of the positioning column 151 is set as a large semicircular ring, and a U-shaped positioning block 152 is provided on the outer side of the root of the positioning column 151. The width of the U-shaped positioning block 152 toward one end of the plug-in end 15 is greater than the width toward the end of the load-bearing end 14, and the root of the U-shaped positioning block 152 is flush with the root of the positioning column 151, and the height of the U-shaped positioning block 152 is less than the height of the positioning column 151.

[0031] In the present invention, when mating and matching, the positioning column 151 of the present invention first enters the male end to be mated for preliminary positioning. As the insertion goes deeper, the U-shaped positioning block 152 performs secondary positioning with the male end to ensure that the mating accuracy of the male end and the present invention is better guaranteed, and the stability of the mating is ensured, thereby extending the service life of the present invention.

[0032] In summary, the utility model is designed with a heat dissipation structure with high heat dissipation efficiency, and the positioning column 151 and the U-shaped positioning block 152 of the utility model ensure the accuracy and stability of the mating between the male end and the utility model, thereby extending the service life of the utility model.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
