Nor are they used to limit the present utility model. They are merely used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
[0027] This embodiment provides a high-power connector with strong guiding ability. A guiding housing 30 is arranged inside a plastic housing 20 of the connector, which can perform precise guiding during the insertion process of the connector and the bus bar. Its guiding effect is good, and it can effectively avoid the situation of connector damage caused by insufficient plastic strength, enabling the connector to have strong guiding performance. A spring piece 11 is arranged outside a terminal 10, and the terminal 10 is clamped by the spring piece 11, so that a very low contact impedance can be obtained, enabling the connector to carry a higher current and enhancing the service life of the connector.
[0028] Combined Figures 1 to 4 As shown, the high-power connector with strong guiding ability in this embodiment includes a terminal 10, a plastic housing 20, and a guiding housing 30. The terminal 10 and the guiding housing 30 are both located inside the plastic housing 20. The guiding housing 30 can perform precise guiding during the insertion process of the connector and the bus bar, enhancing the guiding performance of the connector to avoid damage to the connector.
[0029] In this embodiment, the connector further includes a copper bar 40. The terminal 10 is detachably connected to the copper bar 40 through a mounting member 50. The copper bar 40 in this embodiment is a T-shaped structure, and the copper bar 40 is connected to the copper bar inside the battery module.
[0030] As Figure 2As shown in the figure, a shrapnel 11 is arranged outside the terminal 10 of this embodiment. The shrapnel 11 is attached to the terminal 10 and clamps the terminal 10. The terminal 10 of this embodiment is a copper part with high conductivity, while the shrapnel 11 is a stainless steel structural part. In this embodiment, a copper part with high conductivity is used as the terminal 10, and the multi-contact point structure on the surface of the terminal 10, combined with the use of the stainless steel shrapnel 11, can enable the terminal 10 to obtain a very low contact impedance, enabling the connector to carry a current of 1000 A, and improving the insertion and extraction life of the connector.
[0031] Combined with Figure 1 、 Figure 3 and Figure 4 As shown in the figure, an embedding channel 21 is provided on the plastic housing 20 of this embodiment. The bus bar is inserted into the terminal 10 through the embedding channel 21. The opening of the terminal 10 and the opening of the embedding channel 21 are in the same position, enabling the bus bar to be smoothly inserted into the terminal 10 through the embedding channel 21 to complete the plugging operation between the connector and the bus bar. The guiding housing 30 is located inside the plastic housing 20, and part of the guiding housing 30 protrudes from the embedding channel 21 to guide the inserted bus bar. The guiding housing 30 of this embodiment is a stainless steel structural part, and guiding parts 31 are provided at both ends of the guiding housing 30. The two groups of guiding parts 31 are arranged in parallel to guide the insertion of the bus bar. Since part of the guiding housing 30 protrudes into the embedding channel 21, during the plugging process between the bus bar and the connector, the bus bar will not contact the plastic housing 20, effectively avoiding damage to the plastic housing 20 and realizing strong guiding operation of the connector.
[0032] In this embodiment, installation slots 22 are provided on the plastic housing 20. The installation slots 22 are located on both sides of the embedding channel 21. The guiding parts 31 are arranged in the installation slots 22, and the guiding parts 31 protrude from the installation slots 22 and partially located in the embedding channel 21. During the plugging process between the connector and the bus bar, the bus bar enters the terminal 10 through the guiding parts 31, avoiding direct contact between the bus bar and the plastic housing 20 to protect the plastic housing 20.
[0033] In the actual use of the high-power connector with strong guiding ability in this embodiment, by arranging the guiding housing 30 inside the plastic housing 20, precise guiding can be carried out during the plugging process between the connector and the bus bar. Its guiding effect is good, which can effectively avoid the situation of connector damage caused by insufficient plastic strength, enabling the connector to have strong guiding performance. By arranging the shrapnel 11 outside the terminal 10 and clamping the terminal 10 with the shrapnel 11, a very low contact impedance can be obtained, enabling the connector to carry a higher current and enhancing the service life of the connector.
