Abstract

A shielding terminal includes an inner terminal 11 to be connected with a core 2, an outer terminal 12 to be connected with a braided wire 4, a dielectric element 13 for insulating the two terminals 11 and 12 from each other, and a cover 14 to be mounted on an upper portion of the outer terminal 12. After the core 2 is fastened to an inner fastening portion 18 of the inner terminal 11 outside the outer terminal 12, the inner terminal 11 is inserted into the dielectric element 13. An outer fastening portion 22 of the outer terminal 12 is crimped into connection with a section 4A of the braided wire 4 folded back around an end of a sheath 5. In the center of the outer terminal 12, the upper surface is opened to provide an open space 21A. The fastened portion of the core 2 is covered on four sides by mounting the cover 14 to cover the open space 21A.

Claims

1. A shielding terminal to be connected with an end of a shielded cable comprised of a core provided substantially in the center of the cable, an insulating layer surrounding the core, a shield layer surrounding the insulating layer, and a sheath surrounding the shield layer, the shielding terminal comprising:

an inner terminal having a fastening portion configured for connection with the core,

a dielectric element accommodating at least part of the inner terminal,

an outer terminal accommodating the dielectric element and being connectable with the shield layer, the outer terminal being configured for surrounding three sides of the inner terminal and leaving an exposed portion on a fourth side of the inner terminal, and

a cover having a covering portion substantially covering the exposed portion on the fourth side of the inner terminal, and at least one mount portion mountable on a section of the outer terminal to be connected with the shield layer,

wherein at least one assembling piece is arranged substantially along a side wall of the outer terminal and is formed with at least one displacement restricting portion for restricting displacement of the cover.

2. A shielding terminal according to claim 1, wherein the at least one assembling piece extends from the covering portion of the cover.

3. A shielded terminal according to claim 1, wherein the at least one displacement restricting portion restricts the displacement of the cover by being held substantially in contact with a connecting wall that connects with the side wall of the outer terminal, the connecting wall being a bottom wall of the outer terminal.

4. A shielding terminal according to claim 3, wherein each displacement restricting portion comprises a first displacement restricting portion that is held in contact with the side wall of the outer terminal and a second displacement restricting portion that is held in contact with the connecting wall.

5. A shielding terminal according to claim 4, wherein two displacement restricting portions and two side walls are provided, the displacement restricting portions being inserted between the side walls of the outer terminal and side walls of the dielectric element.

6. A shielding terminal according to claim 5, wherein the displacement restricting portions prevent the assembling pieces from being bent inward of the outer terminal.

7. A shielding terminal according to claim 6, wherein the at least one mount portion comprises a clip-lock.

8. A shielding terminal according to claim 1, wherein the exposed portion of the inner terminal comprises the fastening portion.

9. A shielding terminal according to claim 1, wherein portions of the cover at the exposed portion of the inner terminal define a spacing from the inner terminal that is less than a spacing between the outer terminal and the inner terminal adjacent the exposed portion, such that the outer terminal defines an engaging edge for engaging a locking latch.

10. A method for connecting a shielding terminal with an end of a shielded cable, the shielded cable comprising a core provided substantially in the center of the cable, an insulating layer surrounding the core, a shield layer surrounding the insulating layer, and a sheath surrounding the shield layer, the method comprising the steps of:

connecting an inner terminal with the core,

at least partly accommodating the inner terminal in a dielectric element,

at least partly accommodating the dielectric element and the inner terminal in an outer terminal such that three sides of the inner terminal are surrounded by the outer terminal and such that an exposed portion is defined on a fourth side of the inner terminal,

connecting the outer terminal with the shield layer, and

substantially covering the exposed portion of the inner terminal connected with the core with a cover,

wherein the covering step comprises;

mounting at least one mount portion of the cover on a section of the outer terminal connected with the shield layer, and

arranging at least one assembling piece substantially along a side wall of the outer terminal for restricting a displacement of the cover.

11. A method according to claim 10, wherein the covering step further comprises a step of bringing at least one displacement restricting portion into contact with a connecting wall substantially connecting the side walls of the outer terminal.
