Description

Technical Field

[0001] This utility model relates to the field of charger technology, and in particular to a female terminal structure for a battery pack charging and discharging plug. Background Technology

[0002] The existing female terminal used in battery pack charging and discharging plugs has its terminal block located in a U-shaped slot. The male terminal is inserted through the opening of the U-shaped slot and contacts the terminal block to achieve power supply.

[0003] However, with this type of female terminal, the U-shaped slot keeps opening during the insertion of the male terminal, which can easily cause poor contact over time and affect normal use. Secondly, the battery pack charging and discharging plug is a high-current input, and if there is poor contact between the male and female terminals, it is very easy to generate sparks and cause a fire, so the safety of use cannot be guaranteed. Summary of the Invention

[0004] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a female terminal structure for a battery pack charging and discharging plug.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a female terminal structure for a battery pack charging and discharging plug, including a mounting base plate, a U-shaped seat with a front opening fixedly connected to the side end of the mounting base plate, a female terminal connector embedded in the U-shaped seat, and support columns respectively provided on both sides of the opening end of the U-shaped seat. The support columns extend from the upper two sides of the opening end of the U-shaped seat and bend towards the lower two sides of the opening end of the U-shaped seat. The lower ends of the support columns are fixedly connected to both sides of the lower end face of the opening end of the U-shaped seat.

[0006] Specifically, the U-shaped seat has connecting columns fixed to both sides of the lower end of the opening, and the lower end of the support column has a snap-fit ​​hole that engages with the connecting column.

[0007] Furthermore, main heat dissipation holes are respectively opened on the upper end face and the lower end face of the U-shaped seat, and secondary heat dissipation holes are respectively opened on both sides of the main heat dissipation holes.

[0008] To better facilitate the insertion and mating with the male terminal, the upper end face of the U-shaped seat opening has an upper boss at its center, and the lower end face of the U-shaped seat opening has a lower boss corresponding to the upper boss at its center. The lower end face of the upper boss has a lower protrusion, and the upper end face of the lower boss has an upper protrusion corresponding to the lower protrusion. The upper end face of the upper boss has an upper right-angle notch, and the lower end face of the lower boss has a lower right-angle notch.

[0009] The beneficial effects of this utility model are as follows: By setting support columns on both sides of the opening of the U-shaped seat of the female terminal block, and fixing the lower ends of the support columns to both sides of the lower end face of the opening of the U-shaped seat, the overall strength of the female terminal of the plug is improved, ensuring good insertion of the male and female terminals and improving the safety of the charging and discharging plug. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] In the diagram: 1. Mounting base plate, 2. U-shaped seat, 3. Female terminal block, 4. Support column, 5. Connecting column, 6. Snap-fit ​​hole, 7. Main heat dissipation hole, 8. Secondary heat dissipation hole, 9. Upper boss, 10. Lower boss, 11. Lower protrusion, 12. Upper protrusion, 13. Upper right-angle notch, 14. Lower right-angle notch. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0014] like Figure 1 The battery pack charging and discharging plug female terminal structure shown includes a mounting base plate 1, a U-shaped seat 2 fixedly connected to the side end of the mounting base plate 1, the front end of the U-shaped seat 2 is open, and a female terminal terminal block 3 that is plugged into and energized with the male terminal is embedded in the U-shaped seat 2. The female terminal terminal block 3 is a U-shaped structure adapted to the inner cavity of the U-shaped seat 2.

[0015] The U-shaped seat 2 has support columns 4 on both sides of the opening end. The support columns 4 extend from the upper side of the opening end of the U-shaped seat 2 and bend towards the lower side of the opening end of the U-shaped seat 2. The lower side of the opening end of the U-shaped seat 2 is fixed with connecting columns 5. The lower end of the support column 4 has a snap-fit ​​hole 6 that engages with the connecting column 5.

[0016] To improve heat dissipation during plug use, main heat dissipation holes 7 are respectively provided on the upper and lower surfaces of the U-shaped base 2, and secondary heat dissipation holes 8 are respectively provided on both sides of the main heat dissipation holes 7; and rectangular holes corresponding to the positions of the secondary heat dissipation holes 8 are respectively provided on the upper and lower surfaces of the female terminal block 3.

[0017] The U-shaped base 2 has an upper boss 9 at the center of its upper end face, and a lower boss 10 corresponding to the upper boss 9 at the center of its lower end face. The lower end face of the upper boss 9 has a lower protrusion 11, and the upper end face of the lower boss 10 has an upper protrusion 12 corresponding to the lower protrusion 11. The upper end face of the upper boss 9 has an upper right-angle notch 13, and the lower end face of the lower boss 10 has a lower right-angle notch 14. With this structure, the U-shaped base 2 can be more easily plugged into and installed with a male terminal block.

[0018] Preferably, for ease of integrated manufacturing, the mounting base 1 and the U-shaped seat 2 are an integral structure.

[0019] This invention improves the overall strength of the female terminal of the plug by setting support columns 4 on both sides of the opening of the U-shaped seat 2 where the female terminal block 3 is installed, and fixing the lower ends of the support columns 4 to both sides of the lower end face of the opening of the U-shaped seat 2, thereby ensuring good insertion of the male and female terminals and improving the safety of the charging and discharging plug.

[0020] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
