Wire harness structure and transmission line

Abstract

This application discloses a wire harness structure and transmission line, in which an extension section is covered by a covering portion, and a lead-out section extends from the extension section to the outside of the covering portion. Simultaneously, slots are formed between the plurality of extension sections. Thus, inserting a plug into the slot, with the limiting head located outside the covering portion, improves the mechanical strength of the wire harness end, preventing easy bending of the wire harness end. Furthermore, a limiting body located laterally to the plug increases the limiting head, fixing the limiting body and the lead-out section to the fixing portion, preventing the reinforcing portion from moving towards the bottom of the slot. Simultaneously, it allows the plurality of first connecting ends to stably connect with the plurality of contacts.

Claims

1. A wire harness structure, comprising: One fixed part; A wire bundle includes a covering portion and a plurality of single wires, each single wire including a lead-out section and an extension section. The covering portion covers the extension sections, forming a slot between the extension sections. One end of the lead-out section is connected to the extension section, and the other end forms a first connection end. The lead-out sections are fixedly connected to a fixing portion, and the first connection ends extend from the fixing portion. A reinforcing portion includes a limiting head and a plug rod. One end of the plug rod is inserted into the slot, and the other end extends from the slot and is connected to the limiting head. The limiting head includes a limiting body. In the direction of the projection of the limiting head onto the plug rod, the limiting body is located outside the plug rod, and the side of the limiting head near the plug rod abuts against the fixing portion.

2. The wire harness structure as described in claim 1, wherein, The insertion rod includes a connecting section and a plug section in the extension direction. One end of the connecting section is connected to the limiting head, and the other end is connected to the plug section. The plug section is inserted into the slot and laterally abuts against the extension sections.

3. The wire harness structure as described in claim 2, wherein, The lead-out section also includes a fixing section, one end of which is connected to the first connecting end; the fixing part is an injection molded part, which includes covering the fixing section and the limiting head.

4. The wire harness structure as described in claim 3, wherein, The fixed section and the extension section are connected at one end to form a second connection end; the second connection ends are arranged around the connection section, and a filling gap is formed between the second connection ends and the connection section; the fixed part fills the filling gap.

5. The wire harness structure as described in claim 3, wherein, In the direction of extension of the extension segment, the covering portion includes a port from which the lead-out segments extend; the fixing portion covers the port.

6. The wire harness structure as described in claim 1, wherein, The surface of the limiting head is curved.

7. The wire harness structure as described in claim 1, wherein, The limiting head is a spherical notch, which includes a spherical crown and a circular surface, the diameter of which is larger than ...

8. The wire harness structure as described in claim 1, wherein, These first connecting ends extend toward the side of the fixing part away from the covering part and are arranged in a straight line.

9. The wire harness structure as described in claim 1, wherein, The reinforcing part includes a metal core and a shielding layer. The shielding layer covers the outer surface of the metal core and forms the limiting head and the insertion rod with the metal core, respectively.

10. The wire harness structure as described in claim 2, wherein, The reinforcing part has a bending strength greater than or equal to 150 MPa and an impact toughness greater than or equal to 10 J / cm2; and / or the insertion section is interference-fitted with the slot, and the length of the insertion section is greater than or equal to 5 mm.

11. A transmission line, comprising: A connector includes a socket and a circuit board including a plurality of contacts; and a wire harness structure as described in any one of claims 1 to 10, wherein the first connection ends are respectively connected to the contacts.
