Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically, to a split connector. Background Art

[0002] The shell of the existing connector is manufactured as a whole, that is, the shell is integral and cannot be separated. Under the influence of narrow operating space and numerous related structures, the actual assembly operation is relatively inconvenient, especially when the power terminal and the cable are directly crimped and then fixed in the shell. A conventional method is to open an operation window on the shell, but when the power terminal is small, the number is large, and the design space is limited, the convenience of the assembly operation cannot be improved; in addition, the high-voltage connector is usually provided with an interlocking terminal for short-circuiting the interlocking signal circuit of the mating connector. The existing technical means is to integrally inject the interlocking terminal into the shell, or reserve an interlocking installation position in the shell, install the interlocking terminal in the interlocking sleeve, and then install the interlocking sleeve on the interlocking installation position of the shell. The problem with this technical means is that once the mating connector has a different model due to the change in the setting position of the interlocking signal circuit, the above-mentioned integrally manufactured shell needs to be redesigned to enable the interlocking terminal to work correctly. The original connector product cannot adapt to the above-mentioned different models of mating connectors, so the adaptability is poor. Utility Model Content

The operating space is sufficient, and the convenience of the assembly operation is essentially improved. Even when the power terminals are small, large in number, or the design space is limited, convenient assembly can be performed.
