In addition, in the electric connector 1 involved in present embodiment, the maximum outside diameter and first of the first external conductor 11
The maximum outside diameter of insulating element 12 is less than or equal to the minimum diameter of the inside of the another side of shell 2.With this configuration, this implementation
The electric connector 1 of mode can be from the constituent element of the opening side 2i (another side) assembling whole of shell 2.Therefore, exist
It does not need to carry out overturning shell 2 into the operation waited in assembling process, therefore manufacture becomes easy.
(other embodiments)
In the above-described embodiment, it although having used the shell 2 being made of conductor, also can be used by structures such as resins
At insulating properties shell.In this case, can be set for being electrically connected the first external conductor 11 and the second external conductor 21
The connecting component of electric conductivity, or the first external conductor 11 and the second external conductor 21 are integrally constituted object.
As discussed above, the present invention has the intensity that will not reduce inner conductor and to have manufacturing cost cheap
Simple construction inner conductor effect, what it is for electric connector is useful on the whole.
