High-frequency coaxial electrical connector with shields covering cable conductors and terminals
A female high-frequency connector includes a female inner terminal connected to a core wire of a cable in which an outer periphery of an insulator covering the core wire is covered with a braid, a female inner housing accommodating the female inner terminal in an inner terminal accommodating chamber, a tubular female shield body covering an outer periphery of the female inner housing, a female crimping member having a braid crimping piece that is crimped from above the braid, and a tubular female shield sleeve having a tubular braid covered portion that is inserted between the insulator and the braid and having a fitting portion that extends from the braid covered portion and is inserted between the outer periphery of the female inner housing and an inner periphery of the female shield body to cover a gap between the braid crimping piece and the female shield body.
1. A high-frequency connector comprising:
an inner terminal connected to a core wire of a cable in which an outer periphery of an insulator covering the core wire is covered with a braid;
an inner housing accommodating the inner terminal in an inner terminal accommodating chamber;
a tubular shield body covering an outer periphery of the inner housing;
a crimping member having a braid crimping piece that is crimped from above the braid and a sheath crimping piece; and
a tubular shield sleeve having a tubular braid covered portion that is inserted between the insulator and the braid and having a fitting portion that extends from the braid covered portion and is inserted between the outer periphery of the inner housing and an inner periphery of the shield body to cover a peripheral gap between the braid crimping piece and the shield body,
wherein the crimping member is a separate piece from the shield body, and
the crimping member is arranged in a rear of the shield body such that the peripheral gap is formed between a rear edge of the shield body and a front edge of the braid crimping piece being a front edge of the crimping member.
2. The high-frequency connector according to claim 1 , wherein
a hole caused by cutting and raising a standing piece is formed in a rear portion of the shield body on a core wire lead-out side, and
the fitting portion blocks the hole.
3. The high-frequency connector according to claim 2 , wherein
the hole is closed by a peripheral connecting portion further rear of the hole extending in a circumferential direction of the shield body, and
the peripheral connecting portion contacts and is electrically connected to an outer periphery of the fitting portion.
4. The high-frequency connector according to claim 1 , wherein
a large diameter portion is formed on the outer periphery of the inner housing in a middle in a direction along an axial line,
the large diameter portion has an inclined contact portion at a front and a vertical pressed portion at a rear,
the shield body is formed with an enlarged diameter portion into which the large diameter portion is fitted so that a boundary with a front portion serves as a contact receiving portion, and
in the inner housing inserted into the enlarged diameter portion of the shield body, the contact portion contacts the contact receiving portion, and the pressed portion is pressed by a pressing portion formed in the fitting portion of the shield sleeve.
5. The high-frequency connector according to claim 1 , wherein
the shield sleeve is bent in an L shape.
6. The high-frequency connector according to claim 1 , wherein the crimping member is axially spaced from the shield body.
