Problems solved by technology

In the case of connecting the flexible flat cables having a shield structure like this, when a method of piercing the connecting member in a state where a plurality of flexible flat cables are stacked up and down is used as in the prior art, the connecting member is not damaged. Surrounded by the shielding layer, there is a problem that the electromagnetic shielding of the connecting member cannot be performed

Embodiment approach 1

[0058] while referring to Figure 1 to Figure 17Embodiment 1 of the technology disclosed in this specification will be described. The branch box 10 of this embodiment includes: a housing 11; a main cable 12 (an example of a main flexible flat cable) fixed to the housing 11; a branch cable 13 (an example of a branch flexible flat cable) fixed to the housing 11; The relay path 14 electrically connects the main cable 12 and the branch cable 13 ; and the cover 15 is assembled to the housing 11 . The branch box 10 is mounted, for example, in vehicles (not shown) such as an electric car and a hybrid car, and branches the power circuit and the signal circuit. In the following description, the Z direction will be described as upward, the Y direction will be referred to as front, and the X direction will be described as left. In addition, with regard to a plurality of identical members, reference numerals may be assigned to only some members, and reference numerals may be omitted for...

Embodiment approach 2

[0163] Next, while referring to Figure 18 to Figure 25 The branch box 80 according to Embodiment 2 of the technology disclosed in this specification will be described.

[0164] cover 81

[0165] Such as Figure 19 As shown, in the rear portion of the upper wall of the cover 81 and in the portion extending in the left-right direction, a base operating hole 82 extending in the front-rear direction penetrates vertically. The trunk operation hole 82 is rectangular when viewed from above. A hole edge portion of the trunk operation hole 82 is formed as a frame portion 83 protruding slightly upward from the upper wall of the cover 81 . A sub-cover locking receiving portion 85 is formed at the front end of the frame portion 83 so as to bulge forward, and a sub-cover locking claw 84 to be described later is locked to the sub-cover locking receiving portion 85 .

[0166] At the rear end of the trunk operation hole 82 , a trunk sub-cover 86 extending rearward is integrally formed wi...

Embodiment approach 3

[0198] Next, while referring to Figure 26 to Figure 29 Embodiment 3 of the technology disclosed in this specification will be described.

[0199] Such as Figure 27 As shown, the insulating plate 110 is made of insulating synthetic resin and has a substantially rectangular shape when viewed from above. The insulating plate 110 has: the first slit 74 on the insulating plate side, which is bent into an L-shape when viewed from above; Watching extends in a front-to-back direction.

[0200] The first trunk-side bus bar 56 , first branch-side bus bar 60 , second trunk-side bus bar 62 , second branch-side bus bar 63 , and relay bus bar 64 are arranged on the upper surface of the insulating plate 110 . A plurality of ribs 72 protruding upward are formed on the upper surface of the insulating plate 110 . By interposing the rib 72 , the first trunk-side bus bar 56 , the first branch-side bus bar 60 , the second trunk-side bus bar 62 , the second branch-side bus bar 63 , and the re...

Abstract

A main cable 12 comprises a main conductor 31 for signals, which is electromagnetically shielded by a shield layer 35. A branch cable 13 comprises a branch conductor 38 for signals, which is electromagnetically shielded by a shield layer 42. The main conductor 31 for signals and the branch conductor 38 for signals are electrically connected to each other by means of a relay bus bar 64 which is electromagnetically shielded by a base shield member 65 and a cover shield member 27.

Description

technical field [0001] The technology disclosed in this specification relates to a connection structure of a plurality of flexible flat cables. Background technique [0002] Conventionally, a flexible flat cable is known that has a conductive path and a flexible insulating layer that surrounds the conductive path. Since the flexible flat cable has flexibility, it can be suitably used in a case where wiring in a limited space is required, such as in a vehicle. [0003] As a technique for connecting a plurality of flexible flat cables, the technique described in JP 2003-168508 A is known. According to this technique, the conductive path of the lower flexible flat cable and the conductive path of the upper flexible flat cable are connected by piercing the connecting member in a state where the plurality of flexible flat cables to be connected are vertically overlapped. The components are electrically connected. [0004] prior art literature [0005] patent documents [000...
