In the example, the covering seat has a main seat 32 and a back plate 31 formed integrally with the main seat, and the lower surface of the main seat (i.e. the front surface of the back plate) forms a clamping space 33. The plurality of plug-in portions 1111, 1211 of the wire terminal are arranged in the clamping space (such as Figure 9 ), so as to be adapted to external related equipment. In the example, the positioning seat, the plug-in portions near or exposed from the positioning seat, and a part of the plurality of sleeves near the positioning seat are all embedded in the covering seat, and the other part of the sleeves is exposed to the back plate and forms wire tails.
