Description

Technical Field

[0001] This invention relates to the field of wire technology, and more specifically, to a multi-wire integrated harness. Background Technology

[0002] Currently, wire harnesses integrate multiple wires. During operation, the wires generate heat due to the current flowing through them. This heat tends to accumulate within the wire harness and cannot dissipate, leading to abnormally high temperatures and insulation aging. Therefore, it is necessary to control the power of the wire harness and strengthen monitoring. This imposes many constraints on high-power design requirements, thus necessitating improvements in the heat dissipation capacity of the wire harness. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-wire integrated harness that improves the heat dissipation capacity of the harness.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-wire integrated harness, comprising an outer sheath and multiple wire sleeves, each wire sleeve comprising a wire base, a wire body mounted on the wire base, an outer sheath mounted on the outer wall of the wire base, a cavity formed between the outer sheath and the wire sleeve, the wire body passing through the cavity, the wire sleeve having through holes and channels, the axial ends of the through holes respectively connecting the cavity and the channels, and air flowing through the channels so that air in the cavity flows to the channels through the through holes.

[0005] The invention is further configured such that end caps are installed at both ends of the wire harness, the end caps are provided with interfaces, one of the end cap interfaces is connected to an air inlet device, and the end cap is provided with a cavity, which is connected to the interface, the channel and the cavity.

[0006] The invention is further configured such that one end of the axial direction of the sleeve is provided with a countersunk hole and the other end is provided with a ball head. The ball head of one sleeve is inserted into the countersunk hole of an adjacent sleeve. The ball head includes an upper spherical surface and a lower spherical surface. The lower spherical surface is located close to the bottom surface of the countersunk hole. The upper spherical surface is at least partially inserted into the countersunk hole. The countersunk hole is provided with an arc surface, and the arc surface is in contact with the outer wall surface of the upper spherical surface.

[0007] The invention is further configured such that the through hole is connected to the circumferential wall of the countersunk hole, and the distance between the through hole and the bottom surface of the countersunk hole is greater than the minimum distance between the ball head and the bottom surface of the countersunk hole.

[0008] The invention is further configured to include a pad, which is fitted onto the upper spherical surface. The pad is made of an elastic material, and the two ends of the pad abut against two adjacent thread sleeves respectively.

[0009] The present invention is further configured such that the sleeve is formed by splicing a first sleeve body and a second sleeve body, and the first sleeve body and the second sleeve body are connected by a fastener.

[0010] The invention is further configured such that the outer wall surface of the ball head is spherical.

[0011] The invention is further configured such that the wire holder has a groove, the wire body is inserted into the groove, and the wall of the groove holds the wire body in place.

[0012] The invention is further configured to include a fastener one, and the outer sheath includes an edge portion one and an edge portion two. The fastener one passes through the edge portion one, the edge portion two, and the second sleeve and is threadedly inserted into the first sleeve.

[0013] In summary, the present invention has the following beneficial effects:

[0014] The high gas velocity and low pressure within the channel allow air to flow from the cavity through the through-holes into the channel, while hot air is exhausted through the channel, improving the heat dissipation capacity of the wiring harness and making it suitable for high-power wiring harnesses. Most of the airflow entering through the interface flows directly through the countersunk hole and into the channel, while a small portion of the airflow entering through the interface enters the cavity through the groove, creating airflow circulation within the cavity to ensure continuous exhaust of hot air and improve overall heat dissipation.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-3 As shown, this embodiment discloses a multi-wire integrated harness, including an outer sheath 2 and multiple wire sleeves 1, which are connected sequentially along the axial direction to form a long strip. Figure 1 This is a partial sectional view showing the connection of three of the line sleeves 1.

[0021] like Figure 2 As shown, the sleeve 1 is formed by splicing a first sleeve 11 and a second sleeve 12. The first sleeve 11 and the second sleeve 12 are connected and fixed by fastener 7, which is made of insulating material.

[0022] The wire sleeve 1 includes a wire base 13, which extends radially outward along the upper outer wall of the wire sleeve 1. An outer sheath 2 is installed on the outer wall of the wire base 13. Specifically, the outer sheath 2 is made of insulating material and has a rectangular structure. The outer sheath 2 includes an edge portion 21 and an edge portion 22, which are located at the two long sides of the outer sheath 2. After the outer sheath 2 wraps around the wire base 13, the edge portion 21 and the edge portion 22 overlap. A fastener 3 passes through the edge portion 21 and the edge portion 22, and the fastener 3 passes through the edge portion 21, the edge portion 22, and the second sleeve body 12 and is threaded into the first sleeve body 11. The fastener 3 is made of insulating material.

[0023] The wire holder 13 is equipped with a wire body 4. Specifically, the wire holder 13 is provided with a groove 131 that penetrates the outer wall of the wire holder 13. Multiple grooves 131 are distributed around the circumference of the wire holder 13. The grooves 131 are used to install the wire body 4. The diameter of the wire body 4 is larger than the opening width of the groove 131. After the wire body 4 is inserted into the groove 131, the wall of the groove 131 holds the wire body 4 to prevent the wire body 4 from becoming loose.

[0024] like Figure 1 As shown, the axial end of the sleeve 1 is provided with a countersunk hole 15 and the other end is provided with a ball head 14. The ball head 14 of one sleeve 1 is inserted into the countersunk hole 15 of the adjacent sleeve 1. The outer wall surface of the ball head 14 is spherical. The ball head 14 includes an upper spherical surface 141 and a lower spherical surface 142. The lower spherical surface 142 is set close to the bottom surface of the countersunk hole 15. The upper spherical surface 141 is at least partially inserted into the countersunk hole 15. The countersunk hole 15 is provided with an arc surface 152. The arc surface 152 fits against the outer wall surface of the upper spherical surface 141. Since the sleeve 1 is formed by splicing the first sleeve body 11 and the second sleeve body 12, the ball head 14 is limited in the countersunk hole 15. The diameter of the ball head 14 and the countersunk hole 15 are the same. The ball head 14 can rotate in the countersunk hole 15 to make the two adjacent sleeves 1 bend, so as to change the winding direction of the wire bundle.

[0025] It also includes a pad 5, which is fitted onto the upper spherical surface 141. The pad 5 is made of elastic material. The two ends of the pad 5 abut against the two adjacent wire sleeves 1 respectively. The pad 5 can open up the two adjacent wire sleeves 1 so that the wire bundle is in a taut state. The pad 5 provides a structural basis for the wire sleeves 1 to bend under external force.

[0026] like Figure 1 As shown, the wire sleeve 1 is provided with a through hole 151, which is connected to the circumferential wall of the countersunk hole 15. Multiple through holes 151 are provided along the circumference of the countersunk hole 15.

[0027] like Figure 1 As shown, a cavity 23 is formed between the outer sheath 2 and the wire sleeve 1. The wire 4 passes through the cavity 23, and the heat generated by the wire 4 after being energized is dissipated within the cavity 23. The wire sleeve 1 has a channel 16 that axially penetrates the wire sleeve 1. The two ends of the through hole 151 are respectively connected to the cavity 23 and the channel 16. Air flows through the channel 16, and the airflow velocity within the channel 16 is relatively fast. According to Bernoulli's principle, the air pressure within the channel 16 is relatively low, so that the air in the cavity 23 flows through the through hole 151 to the channel 16. Figure 1 (Arrow direction) Hot air is exhausted through channel 16 to improve the heat dissipation capacity of the wiring harness, making it suitable for high-power wiring groups. Specifically, such as... Figure 3 As shown, end caps 6 are installed at both ends of the wire harness. Each end cap 6 has an interface 61. One end cap 6's interface 61 connects to an air inlet device, while the other end cap 6's interface 61 is used for air outlet. The end cap 6 has a cavity 62, which communicates with the interface 61, the channel 16, and the cavity 23. The interface 61 connects to the countersunk hole 15. Most of the airflow entering through the interface 61 flows directly through the countersunk hole 15 and into the channel 16. A small portion of the airflow entering through the interface 61 enters the cavity 23 through the groove 131, thus creating airflow circulation within the cavity 23. Simultaneously, because the air temperature inside the cavity 23 is higher than the air temperature inside the channel 16, a pressure difference is created between the cavity 23 and the channel 16, making it easier for the gas inside the cavity 23 to flow into the channel 16, thereby improving heat dissipation.

[0028] like Figure 1 As shown, the distance between the through hole 151 and the bottom surface of the countersunk hole 15 is greater than the minimum distance between the ball head 14 and the bottom surface of the countersunk hole 15. After the air passes through the through hole 151 to the countersunk hole 15, the lower ball surface 142 forms a barrier between the channel 16 and the through hole 151, reducing the airflow from the channel 16 into the through hole 151 and keeping the airflow in the channel 16 smooth.

[0029] The way the first set of body 11 and the second set of body 12 are spliced ​​together makes it easy to disassemble and inspect the internal wire body 4, thus reducing the cost of use.

[0030] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
