Description

Technical Field

[0001] The utility model relates to the technical field of double-core wire harnesses, in particular to a reinforced double-core wire harness. Background Art

[0002] Double-core wire harnesses are commonly used in application scenarios that require the transmission of two independent signals, such as audio signals, data signals, etc. In some specific applications, reinforced double-core wire harnesses are used. Based on the original functions of the double-core wire harness, these wire harnesses improve the mechanical strength and durability of the wire harness by adding additional reinforcement materials or using higher-strength materials, enabling them to withstand greater physical pressure and environmental impacts.

[0003] However, the high-strength outer sheath used in existing reinforced double-core wire harnesses is an integrally formed structure. When local damage occurs, not only does the whole need to be disassembled and replaced, which is costly, but it is also inconvenient to disassemble and replace. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and propose a reinforced double-core wire harness.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A reinforced double-core wire harness includes an insulating sleeve and a detachable high-strength outer sheath. An electromagnetic shielding layer is filled in the insulating sleeve. There are two installation cavities left in the electromagnetic shielding layer, and wire cores are installed in both installation cavities. In this way, through the shielding and separation effect of the electromagnetic shielding layer, electromagnetic interference between the two wire cores can be avoided, thereby ensuring the quality of signal transmission.

[0007] As a preferred technical solution of the utility model, an elastic sheath is fixedly sleeved outside the insulating sleeve. Through the elastic buffering effect of the elastic sheath, energy can be absorbed when the entire double-core wire harness is subjected to external impacts, reducing the stress concentration of the double-core wire harness, thereby protecting the double-core wire harness from damage. And a flame-retardant sheath is fixedly sleeved outside the elastic sheath. The flame-retardant sheath can effectively improve the flame-retardant and fire-proof performance of the double-core wire harness.

[0008] As a preferred technical solution of the utility model, the detachable high-strength outer sheath is fixedly sleeved outside the flame-retardant sheath, and the detachable high-strength outer sheath includes an arched upper sheath, an arched lower sheath, and uniformly distributed locking structures.

[0009] As a preferred technical solution of the utility model, the arched upper sheath and the arched lower sheath are symmetrically distributed up and down.

[0010] As a preferred technical solution of the present utility model, the locking structure includes a threaded hole opened on the arched upper sheath, a threaded locking hole opened on the arched lower sheath, and a locking screw threadedly connected between the threaded hole and the threaded locking hole.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. Through the elastic buffering effect of the elastic sheath, the present utility model can absorb energy when the entire two-core wire harness is subjected to external impacts, reduce the stress concentration of the two-core wire harness, thereby protecting the two-core wire harness from damage. Moreover, a flame-retardant sheath is fixedly sleeved outside the elastic sheath, and the flame-retardant sheath can effectively improve the flame-retardant and fire-proof performance of the two-core wire harness;

[0013] 2. Through the shielding and separation effect of the electromagnetic shielding layer, the present utility model can avoid the situation of electromagnetic mutual interference between the two wire cores, thereby ensuring the quality of signal transmission;

[0014] 3. Through the setting of the detachable high-strength outer sheath, when local damage occurs, the damaged arched upper sheath or arched lower sheath can be disassembled and replaced separately by removing each locking screw, which reduces the replacement cost and is convenient and fast to disassemble and replace.
