Detailed Implementation
[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] like Figure 1-2 As shown, this embodiment provides an automotive-grade high-current connector for power batteries, including two first positioning aids 10, a male housing 20, two rows of mirror-symmetrical female terminals 30, two rows of mirror-symmetrical male terminals 40, a female housing 50, and two second positioning aids 60. The female terminals 30 are installed in the female terminal mounting channel of the male housing 20, and the male terminals 40 are installed in the male terminal mounting channel of the female housing 50. The two first positioning aids 10 are respectively inserted into the male housing 20 from the upper wall and the lower wall, and the two second positioning aids 60 are respectively inserted into the female housing 50 from the upper wall and the lower wall, and the male housing 20 is inserted into the female housing 50.
[0025] Specifically, such as Figure 3 As shown, the male housing 20 has a cuboid structure. An opening is provided at the rear end of the upper wall of the male housing 20, exposing all the female terminal mounting channels in the upper row. The first positioning auxiliary member 10 is disposed within the male housing 20 through the opening. At the rear end of the opening, each female terminal mounting channel has a forward-extending anti-reverse arm 21, which restricts the forward and backward movement of the female terminal 30 within the female terminal mounting channel. At the opening, a second reinforcing rib 22 is provided on the separating sidewall of two adjacent female terminal mounting channels, and a second mounting groove 23 is provided on the second reinforcing rib 22. First fasteners are provided on both the left and right sidewalls of the male housing 20, and a second fastener adapted to the first fastener is provided on the female housing 50 for fastening with the female housing 50. The lower wall of the male housing 20, and the upper and lower walls of the female housing 50, also have the same opening, anti-reverse arm 21, second reinforcing rib 22, and second mounting groove 23 structure as the upper wall of the male housing 20, which will not be described in detail here.
[0026] like Figure 4 , Figure 5 As shown, the first positioning auxiliary component 10 has a comb-shaped cross-section, including an upper sidewall and multiple vertical plates arranged parallel to each other on the lower surface of the upper sidewall. The vertical plates divide the spaced-apart receiving grooves 13 and first mounting grooves 15. A first reinforcing rib 14 is provided in the first mounting groove 15. The position and number of the receiving grooves 13 are adapted to the female terminal mounting channel. The receiving grooves 13 are used to accommodate the anti-retraction arm 21. The first reinforcing rib 14 is used to match and install with the second mounting groove 23. The first mounting groove 15 is used to match and install with the second reinforcing rib 22. The vertical plates are inserted into the female terminal mounting channel to restrict the left and right movement of the female terminal 30 within the female terminal mounting channel. The matching installation of the first reinforcing rib 14 and the second mounting groove 23, and the matching installation of the first mounting groove 15 and the second reinforcing rib 22, increases the tightness and strength between the first positioning auxiliary component 10 and the male housing 20. In addition, the first positioning auxiliary component 10 is also provided with a plurality of latching parts 11 and latching openings 12. The latching parts 11 are used to lock the first positioning auxiliary component 10 to the male housing 20, and the latching openings 12 are used to facilitate the removal of the first positioning auxiliary component 10 from the male housing 20. The structure of the second positioning auxiliary component 60 is the same as that of the first positioning auxiliary component 10, and will not be described in detail here.
[0027] During installation, the connector is first inserted into the male housing 20 along the female terminal mounting channel until the anti-reverse arm 21 abuts against the female terminal 30. Next, the first positioning auxiliary member 10 is inserted into the male housing 20 through the opening to limit the left and right movement of the female terminal 30. Similarly, the male terminal 40 and the second positioning auxiliary member 60 are inserted into the female housing 50. Finally, the male housing 20 is inserted into the female housing 50 until the first and second locking members engage.
[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
