Problems solved by technology

[0010] However, the greater the number of shielded single-core wires 20 in the shielded electric wire 10, the connection between the many shielded single-core wires 20 exposed by removing the sheath portion 18 and the shielding foil 21 and the male terminal 12, and the shielded connector. Considering the ease of assembly of 11, the more limited the length of the exposed part is, the more likely it is that the impedance mismatch will be caused.

Embodiment 1

[0047] Hereinafter, Embodiment 1 of the present invention will be described based on the drawings.

[0048] figure 2 The 8-core composite shielded electric wire 30 used in the shielded connector and its connection method of the present invention is shown. The composite shielded electric wire 30 in this example has 6 shielded single-core wires, of which 4 shielded single-core wires 31 are high-speed wires used in differential signal transmission and the like, and the two shielded single-core wires 32 include medium-speed wires. The composite shielded electric wire 30 also has two power lines 33 and one drain wire 34.

[0049] The conductor 31a at the center of the four high-speed wires 31 is covered by an insulator 31b, and the outer periphery is covered by a single-core wire shielding portion including a horizontally wound shielding portion 31c and an aluminum tape 31d. Similarly, the two medium-speed wires 32 The conductor 32a in the center is covered by an insulator 32b, and th...

Embodiment 2

[0066] Although in the above-mentioned embodiment, the cut-and-raised piece 44 is provided for the high-speed wire 31 for differential signal transmission to achieve impedance matching over the entire area of ​​the exposed portion, the same configuration may be adopted for the medium-speed wire 32. Thus, as figure 1 As shown in (b), a part of the shielding shell 42 is grooved downward to form a cut-and-raised piece 60 of the shielding member of the connector. The single core wire shielding portion of the aluminum tape 32d can thereby achieve impedance matching in the entire area of ​​the exposed portion of the medium-speed wire 32, and can enhance the shielding effect.

[0067] In the above embodiment, the connection between the single-core wire shielding portion of the high-speed wire 31 and the cut-and-raised piece 44 and / or the connection between the single-core wire shielding portion of the medium-speed wire 32 and the cut-and-raised piece 60 has excellent workability, There...

Abstract

The present invention suppresses as much as possible the impedance mismatch that causes the connection operation between the shielded single core wire and the connection terminal that is performed by removing the shield portion at the end. The shielding connector removes the shielding part (36) of the end of the shielding wire (30) to expose a plurality of shielding single core wires (31 and / or 32), and connects the connecting terminal (38) to each shielding part (36) exposed. The conductor at the top of the single core wire (31 and / or 32) keeps the connecting terminal (38) by the inner casing (39), and wraps the inner casing (39) and the shielding unit with the shielding shell (42). The core wire is fixed to the end of the shielded wire (30) through the fixing piece (47) integrated with the shielding shell (42), wherein the shielding member of the connector is arranged on the shielding shell (42) (43), electrically connecting the shielding member (43) of the connector to the exposed single-core wire shielding portion of the shielded single-core wire (31 and / or 32).

Description

Technical field [0001] The present invention relates to a shielded connector and a connection method thereof. The shielded connector is a shielded connector that connects a composite cable with multiple shielded single-core wires to a single shielded wire. It becomes an open ground, and impedance matching can be achieved in almost the entire area of ​​the connection processing part. Background technique [0002] Such as Image 6 As shown, there is known a shielded connector that connects a composite cable having a plurality of shielded single-core wires to the shielded connector (Patent Document 1). [0003] The Image 6 In the connection part of the shielded wire 10 with the shielded connector 11, the sheath portion 18 and the shielding foil 21 are removed to expose a plurality of shielded single core wires 20, and the conductors of the shielded single core wires 20 are exposed and male terminals are used. The crimping part 22 of 12 is connected. Each male terminal 12 is accommoda...
