At this time, the first shell 100 can be further positioned and positioned, so as to effectively improve the retention force of the first shell 100, and the structure can still be stable even if deformation occurs under the conditions of multiple plugging and using in high temperature environment.

[0033] It should be noted that the size of the first limiting portion 140 is greater than the size of the second limiting portion 160, and the size of the first limiting groove 211 is greater than the size of the second limiting groove 212, at this time, on the one hand, it can ensure that the second shell 200 is smoothly assembled into the accommodating cavity 110, and the main body portion 210 can be smoothly abutted with the first limiting portion 140, and the connecting portion 220 can be smoothly output outside the first shell 100, so as to ensure that the assembly between the first shell 100 and the second shell 200 reaches the expected effect.

[0034] As shown, Figure 2 In some embodiments, the first shell 100 further comprises at least one second interference protruding rib 170, the second interference protruding rib 170 extends along the axial direction X, and each second limiting portion 160 is connected to at least one second interference protruding rib 170.

[0035] In the embodiment of the present application, by setting the second interference protruding rib 170, on the one hand, the gap between the second limiting portion 160 and the main body portion 210 can be absorbed, and the interference fit between the second interference protruding rib 170 and the main body portion 210 can further improve the positioning and supporting effect of the second shell 200 on the first shell 100 after being fixed, so as to further improve the holding force of the first shell 100.

[0037] In this embodiment, two symmetrically arranged second limiting parts 160 and two symmetrically arranged second limiting grooves 212 are provided in a one-to-one correspondence. This can further improve the stability of the fixed fit between the first housing 100 and the main body 210, and improve the circumferential positioning and limiting effect of the main body 210 on the first housing 100. This can further reduce the possibility of the first housing 100 shaking.

[0038] like Figures 1-4 As shown in some embodiments, the connecting portion 220 includes a plurality of connecting posts 221, which are spaced apart and all connected to the main body portion 210.

[0039] In this embodiment, by setting multiple spaced connecting posts 221, the second housing 200 can be fixed and positioned at multiple points during the assembly of the connector and the circuit board, thereby improving the overall connection and fixing effect of the connector.

[0042] In some embodiments, the first housing 100 is a plastic housing, and the second housing 200 is a zinc alloy housing.

[0043] In this embodiment, the first housing 100 is a plastic housing, which covers the outside of the second housing 200, and the mating ends of the external terminals are also inserted into the receiving cavity 110. Therefore, the plastic housing can maintain insulation. The second housing 200 is a zinc alloy housing, which works in conjunction with the first housing 100. This improves the overall mechanical strength of the connector and provides good support for the first housing 100, preventing connector deformation or bending of the connecting part 220. The zinc alloy has a relatively small coefficient of thermal expansion, which, when combined with the plastic housing, can better maintain the dimensional stability of the connector when the temperature changes. The zinc alloy can effectively shield external electromagnetic interference and prevent electromagnetic leakage of signals inside the connector. Combined with the external plastic housing, it can ensure insulation.

[0044] like Figures 1-3As shown, in some embodiments, the first shell 100 is further provided with a plurality of supporting portions 180, which are arranged on the side of the first shell 100 away from the second opening 130 and surround the first opening 120.
