DETAILED DESCRIPTION

[0038] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0039] like Fig.15 , Fig.16 , Fig.17 , Fig.18 As shown, the connector in the prior art generally includes a plug connector 30 (male) and a socket connector 40 (female) paired with the plug connector 30, wherein the plug connector 30 (male) includes a male end plastic 3001 and a male end terminal 3002 that are plugged into each other, and the socket connector 40 (female) includes a female end plastic 4001 and a female end terminal 4002 that are plugged into each other, so the existing connector needs to distinguish between male and female, and the male and female plastics and terminals are different, have obvious male and female characteristics, and are not interchangeable; that is, both the male and female heads need to have dedicated plastics and terminals, and have dedicated molds, and need to be manufactured using different molds, which increases the manufacturing cost; in this context, the following improvements are made.

[0040] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a hermaphroditic power signal connector includes a connector base 1, which is configured as a rectangular parallelepiped. A power male terminal accommodating cavity 14, a signal male terminal boss 9, a signal male terminal slot 7 and a power male terminal boss 2 are sequentially arranged on the upper side of the connector base 1 along the length direction. A plurality of power male terminal slots 12 are provided at the inner bottom of the power male terminal accommodating cavity 14, and a power male terminal 15 is movably inserted in each of the plurality of power male terminal slots 12. A plurality of signal female terminal slots 11 are penetrated through the upper and lower sides of the inner side of the signal male terminal boss 9, and a plurality of signal female terminal slots 11 are movably inserted in each of the plurality of signal female terminal slots 11. A plurality of signal male terminal slots 7 are provided, and a plurality of signal male terminal slots 7 are movably inserted in each of the plurality of signal male terminal slots 7. A plurality of power female terminal slots 3 are penetrated through the upper and lower sides of the inner side of the power male terminal boss 2, and a plurality of power female terminal slots 3 are movably inserted in each of the plurality of power female terminal slots 3. When in use, the power male terminal 15 on one of the connectors is plugged into the power female terminal 18 on the other connector, and the signal female terminal 16 is plugged into the signal male terminal 17. Before plugging, one of the connectors needs to be rotated 180°.

[0041] The number of the power male terminal 15, the signal female terminal 16, the signal male terminal 17 and the power female terminal 18 can be adjusted according to actual usage. The power male terminal 15 and the power female terminal 18 provide a maximum charging current of 20A, a maximum charging voltage of 100V, and a maximum charging power of 2000W; the signal female terminal 16 and the signal male terminal 17 provide a maximum current of 1A and a voltage of 20V.

[0042] A further improvement of the above scheme is that, Fig.11 , Fig.12 , Fig.13 As shown, one end of the power male terminal 15 is provided with power male terminal corners 1501 on four sides, and the other end of the power male terminal 15 is provided with a circular reinforcement hole 1504. The circular reinforcement hole 1504 can improve the strength and rigidity of the power male terminal 15, avoid deformation of the power male terminal 15, and improve the service life of the power male terminal 15. The two sides of the power male terminal 15 are provided with a power male terminal barb structure 1502 and a power male terminal limiting retaining wall 1503 located at the lower side of the power male terminal barb structure 1502. The barbed structure 1502 of the source male terminal can make the power male terminal 15 tightly clamped in the power male terminal slot 12, so as to facilitate the stable clamping with the power female terminal 18 during subsequent connection to prevent falling off. The power male terminal limiting retaining wall 1503 can limit the power male terminal 15 to improve the installation accuracy and prevent wear. A tuning fork structure 1601 is provided at one end of the signal female terminal 16, and the tuning fork structure 1601 can make the signal female terminal 16 tightly clamped at one end of the signal male terminal 17, so as to improve the clamping effect and make the signal The transmission is more stable. A double contact point protrusion 1602 that cooperates with each other is arranged on the inner side of one end of the tuning fork structure 1601. The double contact point protrusion 1602 can make the signal female terminal 16 and the signal male terminal 17 contact well, improve the stability of the contact surface, and make the small current signal transmission more stable and reliable. The signal female terminal 16 is provided with a signal female terminal barb structure 1603 on both sides and at one end away from the tuning fork structure 1601. The signal female terminal barb structure 1603 can make the signal female terminal 16 better stuck on the signal The signal male terminal 17 is inserted into the tuning fork structure 1601 at one end of the signal female terminal 16 to prevent it from falling off. Signal male terminal corners 1701 are arranged on four sides of one end of the signal male terminal 17. Through the four-sided signal male terminal corners 1701, one end of the signal male terminal 17 can be more conveniently inserted into the tuning fork structure 1601 at one end of the signal female terminal 16 to improve the plugging and unplugging effect. Signal male terminal barb structures 1702 are arranged on both sides of the signal male terminal 17. The signal male terminal barb structures 1702 facilitate the signal male terminal 17 to be clamped in the signal male terminal slot 7 to prevent it from loosening and falling off.

[0043] A further improvement of the above scheme is that, Figure 8 , Fig. 9 , Fig.10As shown, the power female terminal 18 includes a left ear power female terminal 181 and a right ear power female terminal 182 that cooperate with each other. When in use, the left ear power female terminal 181 and the right ear power female terminal 182 are fitted together and inserted into the power female terminal slot 3, so that the power female terminal 18 is plugged and matched with the power male terminal 15. The left ear power female terminal 181 and the right ear power female terminal 182 are both provided with harpoon structures 1812 on both sides. The harpoon structure 1812 can make the power female terminal 18 better inserted into the power female terminal slot 3, thereby improving the plug-in and unplug efficiency. Two arc-shaped elastic contacts 1811 are provided between the two harpoon structures 1812. An arc-shaped elastic contact 1811 can increase the number of contact points, so that the charging current is larger and the charging is more stable. The harpoon structure 1812 and one side of the arc-shaped elastic contact 1811 are jointly provided with a waist-shaped reinforcement hole 1814. The waist-shaped reinforcement hole 1814 can enhance the anti-deformation ability of the power female terminal 18 to prevent the power female terminal 18 from deforming and affecting the good contact. The harpoon structure 1812 is provided with a power female terminal barb structure 1813 on both sides. The power female terminal barb structure 1813 can make the power female terminal 18 more stably inserted into the power female terminal slot 3 to prevent the power female terminal 18 from loosening and falling off and affecting the charging efficiency.

[0044] A further improvement of the above scheme is that, Figure 1 , Figure 2 , Figure 3 As shown, the two sides of the connector base 1 are provided with limit grooves 8 located on the two sides of the signal male terminal boss 9, and the two sides of the connector base 1 are provided with limit plates 5 located on the two sides of the signal male terminal 17 and slidingly matched with the limit grooves 8. Both sides of the signal male terminal boss 9 are vertically provided with anti-fool grooves 10, and the inner sides of the two limit plates 5 are provided with anti-fool convex ribs 6 that are slidably plugged with the anti-fool grooves 10. When in use, two connectors rotated 180° to each other are covered. During the covering process, by inserting the limit plate 5 of one connector into the limit groove 8 of the other connector, the anti-fool convex ribs 6 on the inner side of the limit plate 5 can be inserted into the anti-fool groove 10, so that the two connectors can be covered and positioned, thereby improving the efficiency of installation.

[0045] A further improvement of the above scheme is that, Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig.14As shown, the two sides of the power male terminal accommodating cavity 14 are respectively provided with self-locking elastic buckles 13, and the two sides of the power male terminal boss 2 are respectively provided with self-locking hanging platforms 4 that are engaged with the self-locking elastic buckle 13. The self-locking elastic buckle 13 and the self-locking hanging platform 4 are both provided with self-locking elastic protrusions 20 on the sides that cooperate with each other. One side of the two self-locking elastic protrusions 20 is provided with mutually matching inclined surfaces 19. When in use, two identical connectors are placed upright, and then one of the connectors is vertically flipped 180° so that the two connectors are vertically covered (such as Figure 4 ), so that the self-locking elastic protrusion 20 on the self-locking hanging platform 4 on one connector is snap-fitted with the self-locking elastic protrusion 20 on the other connector through their respective inclined surfaces 19, so that the two connectors are matched together to improve the covering efficiency.

[0046] It should be noted that, when using this hermaphroditic power signal connector, first insert the power male terminal 15 into the power male terminal slot 12, the signal female terminal 16 into the signal female terminal slot 11, the signal male terminal 17 into the signal male terminal slot 7, and the power female terminal 18 into the power female terminal slot 3. Install the other connector in the same way as above, and put one of the connectors in the right position (such as Figure 4 Then turn the other connector vertically 180° (as shown in Figure 4 The upper part), then the limiting plate 5 of the upper connector slides into the limiting groove 8 of the lower connector, and at the same time, the limiting groove 8 of the upper connector slides into the limiting plate 5 of the lower connector. During the sliding process, the anti-fool rib 6 on the inner side of the limiting plate 5 will slide into the anti-fool groove 10, so that the power male terminal 15 in the upper connector is inserted between the left ear power female terminal 181 and the right ear power female terminal 182, and the tuning fork structure 1601 at the lower end of the signal female terminal 16 is inserted into the upper end of the signal male terminal 17, and the self-locking elastic protrusion 20 on the inner side of the self-locking elastic buckle 13 of the upper connector is inserted into the self-locking elastic protrusion 20 on the inner side of the self-locking hanging platform of the lower connector, so that two identical connectors are matched together, so that one connector has a hermaphroditic structure, that is, the male and female functions are realized on one connector, which greatly saves investment costs compared with traditional connectors.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
