In this way, the assembly operation of the inner housing 1 and the locking operation of the terminal 3 are completed.

[0053] However, the present invention is not limited to the illustrated embodiments. For example, in another exemplary embodiment of the present invention, three separate injection molds may also be used to separately manufacture the upper housing 1a, the lower housing 1b, and the partition 1c. After manufacturing the upper housing 1a, the lower housing 1b, and the partition 1c, the upper housing 1a, the lower housing 1b, the partition 1c, and the terminals 3 are assembled together.
