Coaxial connector with efficient assembly operation
First Claim
1. A coaxial connector comprising:
- an insulator assembly including a coaxial cable having a core wire and a braid disposed at the outside of the core wire, an inner conductor terminal having a core wire connection portion connected to the core wire, and an insulator receiving and holding the inner conductor terminal therein;
an outer conductor terminal of a substantially cylindrical shape which has an opening portion for setting the insulator assembly from a direction perpendicular to a longitudinal axis of the outer conductor terminal, and holds the insulator assembly;
a pair of press-crimping pieces for braid connection which are formed at the outer conductor terminal, and are connected to the braid; and
a pair of press-crimping pieces for insulator holding which hold the insulator at an opening edge of the opening portion,wherein the outer conductor terminal has a plurality of spring structural portions for connection to a mating connector, the plurality of spring structural portions being formed at a base portion of the outer conductor terminal disposed at a side opposite from the opening portion and on which the insulator assembly is set, and the spring structural portions being disposed forwardly of the position of the pair of press-crimping pieces for insulator holding.

Abstract
To provide a coaxial connector and an assembling method of the coaxial connector in which an operation efficiency can be enhanced, and also facilities related to the assembling can be simplified. The coaxial connector is assembled through a first step of assembling an insulator assembly, a second step of setting the insulator assembly in an outer conductor terminal through an upper opening portion of the outer conductor terminal from a direction perpendicular to a terminal axis thereof, and a third step of holding an insulator of the insulator assembly by press-crimping a pair of press-crimping pieces for insulator holding and effecting the connection and fixing to a coaxial cable of the insulator assembly by press-crimping a pair of press-crimping pieces for braid connection and a pair of press-crimping pieces for sheath fixation.
