Abstract

A shield terminal includes a braided part crimping member. The shield terminal is connected to a coaxial cable including a core wire, an insulator covering an outer periphery of the core wire, a braided part covering an outer periphery of the insulator and an outer jacket covering an outer periphery of the braided part. The braided part crimping member is crimped with and encloses a braided part exposing portion which is formed by removing the outer jacket to expose the braided part. A wall part of the braided part crimping member which comes into direct contact with the braided part is formed with a round hole so that a part of the braided part enters the round hole in a state where the braided part crimping part is crimped with the braided part exposing portion.

First claim

The invention claimed is:

1. A shield terminal, configured to be connected to a coaxial cable including a core wire, an insulator covering an outer periphery of the core wire, a braided part covering an outer periphery of the insulator and an outer jacket covering an outer periphery of the braided part, the shield terminal comprising:
a braided part crimping member configured to be crimped with and enclose a braided part exposing portion which is formed by removing the outer jacket to expose the braided part,
wherein a wall part of the braided part crimping member which comes into direct contact with the braided part is formed with at least two first circular round holes and at least two second circular round holes so that a part of the braided part enters the first circular round holes and the second circular round holes in a state where the braided part crimping part is crimped with the braided part exposing portion,
wherein the first circular round holes and the second circular round holes are configured to bite the braided part uniformly around respective circumferences of the first circular round holes and the second circular round holes,
wherein the braided part crimping member includes a bottom plate on which the braided part is mounted and a pair of braided part holding pieces extending from both sides of the bottom plate in a direction of width, the first circular round holes are formed in the bottom plate, and the second circular round holes are formed in one of the braided part holding pieces, and
wherein in an assembled state a straight line connects at least one of the first circular round holes and at least one of the second circular round holes, wherein the at least one of the first circular round holes and the at least one of the second circular round holes are configured to receive a fastening force during crimping along the straight line.

2. The shield terminal as set forth in claim 1 , wherein
the first circular round holes and the second circular round holes are arranged in a direction orthogonal to a longitudinal direction of the coaxial cable.

3. The shield terminal as set forth in claim 2 , wherein
the first circular round holes and the second circular round holes are disposed at positions which oppose each other in the state where the braided part crimping member is crimped with the braided part exposing portion.

4. The shield terminal as set forth in claim 1 , wherein
the braided part crimping member comprises the bottom plate and the pair of braided part holding pieces so as to have a U-shape in section,
one of the braided part holding pieces which is rounded inside and comes into direct contact with the braided part is formed with the second circular round holes,
the first circular round holes and the second circular round holes are arranged at positions so as to sandwich the braided part exposing portion therebetween in the state where the braided part crimping part is crimped with the braided part exposing portion.

5. The shield terminal as set forth in claim 4 , wherein
the first circular round holes and the second circular round holes are arranged in a direction orthogonal to a longitudinal direction of the coaxial cable.
