Multiple coaxial connector
A plug includes a housing, a plurality of plug shells that are accommodated in the housing in a manner to protrude from the housing by a predetermined length A, a plurality of plug bodies that are accommodated in the plug shells respectively, and a plurality of plug contacts that are fixed to the plug bodies respectively. A receptacle includes a receptacle shell, a receptacle body, and a receptacle contact. The receptacle shell includes: an accommodation portion that entirely accommodates ends of the plurality of plug shells protruding from the housing, and whose insertion-direction length B satisfies B<A.
1. A multiple coaxial connector comprising:
a plug; and
a receptacle that is connected with the plug, wherein
the plug includes
a housing,
a plurality of plug shells that are accommodated in the housing in a manner to protrude from the housing by a predetermined length A,
a plurality of plug bodies that are accommodated in the plug shells respectively, and
a plurality of plug contacts that are fixed to the plug bodies respectively, and
the receptacle includes
a receptacle shell that includes
an accommodation portion that entirely accommodates ends of the plurality of plug shells protruding from the housing in connector insertion, wherein an insertion-direction length B of the accommodation portion satisfies B<A,
a plurality of through holes in which the plug shells are inserted respectively, and
a guide hole that is positioned between the accommodation portion and the through holes and communicates the accommodation portion and the through holes to each other, and is formed in a manner to taper from the accommodation portion toward the through holes,
a receptacle body that is accommodated in each of the through holes, and
a receptacle contact that is fixed to the receptacle body and is to be fitted to the plug contacts.
2. The multiple coaxial connector according to claim 1 , wherein an end of the receptacle contact is accommodated in the through holes or the guide hole, and a relation between an insertion-direction length D from ends of the plug contacts to the ends of the plug shells and an insertion-direction length E from the end of the receptacle contact to an end of the receptacle body satisfies D−E>0.
3. The multiple coaxial connector according to claim 1 , wherein the guide hole has a cone trapezoidal shape.
4. The multiple coaxial connector according to claim 3 , wherein an end of the receptacle contact is accommodated in the through holes or the guide hole, and a relation between an insertion-direction length D from ends of the plug contacts to the ends of the plug shells and an insertion-direction length E from the end of the receptacle contact to an end of the receptacle body satisfies D−E>0.
5. The multiple coaxial connector according to claim 1 , wherein the receptacle shell is formed so as to satisfy |B+C−A|≤ T when C denotes an insertion-direction length of the guide hole and T denotes a predetermined threshold value.
6. The multiple coaxial connector according to claim 5 , wherein an end of the receptacle contact is accommodated in the through holes or the guide hole, and a relation between an insertion-direction length D from ends of the plug contacts to the ends of the plug shells and an insertion-direction length E from the end of the receptacle contact to an end of the receptacle body satisfies D−E>0.
7. The multiple coaxial connector according to claim 5 , wherein the guide hole has a cone trapezoidal shape.
8. The multiple coaxial connector according to claim 7 , wherein an end of the receptacle contact is accommodated in the through holes or the guide hole, and a relation between an insertion-direction length D from ends of the plug contacts to the ends of the plug shells and an insertion-direction length E from the end of the receptacle contact to an end of the receptacle body satisfies D−E>0.
