Electrical connector which can prevent deformation of core wire of coaxial cable caused by applied pressure onto the coaxial cable at time of crimping outer contact onto the coaxial cable

An electrical connector to be coupled with a coaxial cable including a core wire, an inner insulator layer covering the core wire, an outer conductor layer covering the inner insulator layer and an outer insulator layer covering the outer conductor layer, the electrical connector comprising:

• a contact pin to be connected to the core wire of the coaxial cable;
• an insulating housing for holding the contact pin therein;
• a cylindrical outer contact for covering the insulating housing;
• and
• a crimping member for attaching the outer contact to the coaxial cable,
• wherein a base end portion of the outer contact is located between the inner insulator layer and the outer conductor layer of the coaxial cable,
• wherein the outer contact is attached to the coaxial cable by crimping the crimping member onto the outer conductor layer of the coaxial cable located on the base end portion of the outer contact,
• wherein the crimping member includes a first crimping portion to be crimped onto the outer conductor layer of the coaxial cable so as to surround an outer peripheral surface of the outer conductor layer of the coaxial cable,
• wherein the first crimping portion of the crimping member includes:
• a pair of plate-like portions closed by connecting one end portions of the pair of plate-like portions to each other so as to surround the outer conductor layer of the coaxial cable,
• an engagement concave portion formed on one of the pair of plate-like portions, and
• an engagement convex portion formed on another one of the pair of plate-like portions,
• wherein the engagement concave portion formed on the one of the pair of plate-like portions is engaged with the engagement convex portion formed on the other one of the pair of plate-like portions to prevent the pair of plate-like portions from being opened,
• wherein the engagement concave portion has a shape whose width gradually increases as it is separated from another end portion of the plate-like portion, and
• wherein the engagement convex portion has a shape whose width gradually decreases as it is separated from another end portion of the plate-like portion so as to correspond to the shape of the engagement concave portion.
