Technical Field

[0001] The present invention relates to the field of automotive cables, and in particular to a cable shielding device. Background Art

[0002] At present, high-voltage power cables are an indispensable part of the operation of electric vehicles. Since the high voltage and high current passing through the high-voltage power cables can easily interfere with the normal operation of other parts inside the car, the overall shielding effect of the high-voltage cables will directly affect the performance of the electric vehicle. In the prior art, the branching structure of the shielded cable is complex and costly, and mass production is difficult. There are many manual control points. At the same time, waterproofing is done by using waterproofing putty, and its waterproofing effect is uncontrollable and the risk of failure is high. In actual operation, it is easy to lose the waterproofing effect and cause rework, which increases labor costs, and the assembly process is not simple and convenient enough. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention proposes a cable shielding device, and the specific technical solution is as follows:

[0004] A cable shielding device comprises a shell, multiple groups of shielding sleeves arranged in the shell, crimping terminals arranged in the shielding sleeves, a bus core arranged at one end of the crimping terminal, and a multi-component wire core arranged at the other end of the crimping terminal, the bus core and the branch wire core are both sleeved with wire sleeves on the outside, both ends of the shielding sleeve are provided with outlet tubes on the outside of the wire sleeve, one end of the wire sleeve is arranged in the shielding sleeve, and the other end of the wire sleeve passes through the outlet tube and is arranged on the outside of the shell.

[0005] The present invention adopts a core wire crimping terminal structure, and utilizes the crimping terminal to divide the bus core of a single-core shielded cable into multiple branch wire cores. The wire sleeves arranged on the outside of the bus core and the branch wire cores insulate the wire cores. At the same time, the shielding sleeves arranged on the outside of the crimping terminal isolate the exposed wire cores at the connection between the bus core and the branch wire core and the crimping terminal from the external environment.

[0006] Preferably, the shielding sleeve comprises a shielding shell arranged in the housing and an insulating sleeve arranged between the shielding shell and the crimping terminal, and the inner side surface of the shielding shell is completely fitted with the outer side surface of the insulating sleeve.

[0007] In the present invention, the operator uses an insulating sleeve to isolate the bus core and the external shielding layer, and isolates the branch line core and the external shielding layer, and then puts a shielding shell on the outside of the insulating sleeve to achieve shielding conduction. The inner side of the shielding shell and the outer side of the insulating sleeve are completely fitted to achieve the fixing of the shielding layer and 360° shielding without dead angles in the present invention.

[0008] Preferably, the insulating sleeve comprises two groups of insulating half sleeves arranged on both sides of the crimping terminal, a clamping column is arranged on the inner side of the insulating half sleeve, and a column groove cooperating with the clamping column is arranged on the adjacent insulating half sleeves.

[0017] Preferably, a plurality of sealing rings are provided on the outside of the wire sleeve and between the inner wall of the accommodating hole and the wire sleeve.

[0018] The present invention waterproofs the outer shell and the shielded cable distribution structure in the outer shell by using a sealing ring sleeved between the inner wall of the accommodating hole and the wire sleeve in cooperation with a waterproof plug, thereby preventing moisture from penetrating into the inner shell through the gap between the inner wall of the accommodating hole and the wire sleeve during use and causing a line short circuit.

[0021] Preferably, the material used for the shell is rubber.

[0022] The present invention realizes the insulation function of the shell by using the shell made of rubber

[0023] The present invention has the following beneficial effects:

[0024] The present invention utilizes a crimping terminal to divide the bus core of a single-core shielded cable into multiple branch cores, and the wire sleeves sleeved on the outside of the bus core and the branch core insulate the wire cores. At the same time, the shielding sleeves arranged on the outside of the crimping terminal isolate the exposed wire cores at the connection between the bus core and the branch core and the crimping terminal from the external environment. The present invention has a simple structure and is easy to use, and realizes the branching function of the shielded cable.
