Description

Technical Field

[0001] This application relates to the field of wire harness technology, and in particular to a wire harness structure. Background Technology

[0002] In today's electrical equipment field, wire harnesses are key components for connecting various electrical components and transmitting power and signals. Their performance and design rationality are of paramount importance. As the functions of electrical equipment become increasingly diversified and their structures increasingly complex, the requirements for wire harnesses are also increasing. For the sake of convenient wiring and processing needs, multiple wire harnesses are often integrated together to form a wire harness assembly.

[0003] In existing technologies, wire harness assemblies typically feature a sleeve structure to gather multiple wire harnesses. These sleeves are often cylindrical structures made of plastic or flame-retardant fiber materials. Some wire harnesses even have multiple sleeves, such as a flame-retardant sleeve placed over a plastic protective sleeve. Due to the overlap of multiple sleeves, the heat dissipation performance of the wire harness is reduced, affecting safety. Moreover, many sleeves in existing technologies only serve to gather the wire harnesses and cannot secure them to the harnesses. During installation or transportation, the internal wire harnesses may move, making wiring inconvenient. Therefore, it is necessary to design a wire harness structure with good heat dissipation performance and easy wiring. Utility Model Content

[0004] This application provides a wire harness structure with good heat dissipation performance and easy wiring.

[0005] The wire harness structure provided in this application adopts the following technical solution: A wire harness structure includes a wire harness body and a sleeve disposed on the wire harness body. The sleeve includes a protective sleeve, a flame-retardant sleeve, and a fixing sleeve arranged concentrically from the inside to the outside. The protective sleeve, flame-retardant sleeve, or fixing sleeve is provided with a protrusion. Adjacent protective sleeves, flame-retardant sleeves, and fixing sleeves are separated by the protrusion. A fixing part is provided on the outer side of the fixing sleeve.

[0006] Preferably, the protective sleeve is a plastic flexible tube, and the inner and outer sides of the protective sleeve are provided with the protrusions and are connected to the wire harness body and the flame-retardant sleeve through the protrusions. The flame-retardant sleeve is made of glass fiber material, and the fixing sleeve is made of elastic plastic material, with the protrusions provided on the inner side of the fixing sleeve.

[0007] Preferably, the protective sleeve and the protruding strip, as well as the fixing sleeve and the protruding strip, are integrally formed.

[0008] Preferably, there are multiple protrusions that are evenly arranged circumferentially, and the protrusions are arranged along the length of the protective sleeve, flame-retardant sleeve, or fixed sleeve.

[0009] Preferably, the protrusion is in multiple segments, and the length of each segment is less than the length of the protective sleeve, the flame-retardant sleeve, or the fixing sleeve.

[0010] Preferably, the fixing part includes a flat part disposed on the side of the fixing sleeve, and the flat part is provided with a peelable adhesive.

[0011] Preferably, the fixing part is located at both ends of the fixing sleeve.

[0012] Preferably, the main body of the wiring harness includes a control line, a power supply line, and a grounding line. The control line is composed of multiple segments connected end to end. A connection terminal is provided at the connection point of the multiple control lines, and a heat shrink sleeve is fitted on the connection terminal.

[0013] Preferably, the fixed sleeve is provided with locking buckles at both ends, the locking buckles are sleeved on the outside of the flame-retardant sleeve, and the locking buckles are provided with multiple elastic pieces, the elastic pieces are inclined and can be inserted between the fixed sleeve and the flame-retardant sleeve.

[0014] Preferably, the length of the protective sleeve is greater than the length of the flame-retardant sleeve, and the length of the flame-retardant sleeve is greater than the length of the fixing sleeve.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. This application improves the protection of the wire harness body by concentrically setting a protective sleeve, a flame-retardant sleeve, and a fixing sleeve on the outside of the wire harness body. At the same time, the protective sleeve, flame-retardant sleeve, or fixing sleeve is provided with a raised strip to separate the protective sleeve, flame-retardant sleeve, and fixing sleeve, and gaps are formed between each sleeve to facilitate heat dissipation and ventilation, reduce the wire harness temperature, and ensure the stable operation of the wire harness. By setting a fixing part on the outside of the fixing sleeve, the wire harness can be fixed and installation is convenient.

[0016] 2. By providing raised strips on both the inner and outer sides of the protective sleeve, the inner raised strip can use the friction between itself and the main body of the wire harness to fix the protective sleeve and the main body of the wire harness, facilitating installation. At the same time, the raised strips are integrated with the protective sleeve and the fixing sleeve, which facilitates processing and manufacturing. Since the raised strips are evenly arranged axially, the gaps between the protective sleeve and the flame-retardant sleeve, and between the flame-retardant sleeve and the fixing sleeve are uniform, improving the heat dissipation effect. By setting the raised strips to multiple segments, the bending effect of the wire harness structure can be guaranteed, while improving the fixing effect of the internal wire harness main body, making it convenient to use.

[0017] 3. By setting a flat fixing part on the fixing sleeve and providing a peelable adhesive on the fixing part, it can be bonded and fixed, ensuring the fixing effect of the wire harness structure, and at the same time, the angle of the wire harness structure can be adjusted for easy connection.

[0018] 4. By setting the control line to multiple segments and connecting them end to end, the bending of the control line can be reduced. At the same time, the connection points are equipped with connection terminals and heat shrink sleeves to protect the connection points and extend their service life.

[0019] 5. By setting a locking buckle on the fixed sleeve and setting an elastic piece on the locking buckle, the elastic piece can be locked to the flame-retardant sleeve for fixation, thereby locking the position of the fixed sleeve and facilitating connection. Attached Figure Description

The sleeve 2 includes a protective sleeve 201, a flame-retardant sleeve 202, and a fixing sleeve 203 arranged concentrically from the inside to the outside. The length of the protective sleeve 201 is greater than the length of the flame-retardant sleeve 202, and the length of the flame-retardant sleeve 202 is greater than the length of the fixing sleeve 203, for easy assembly. A protrusion 3 is provided on the protective sleeve 201, the flame-retardant sleeve 202, or the fixing sleeve 203. Adjacent protective sleeves 201, flame-retardant sleeves 202, and fixing sleeves 203 are separated by the protrusion 3, so that the protective sleeve... 201. There is a gap between the flame-retardant sleeve 202 and the fixed sleeve 203 to improve the heat dissipation performance of the wire harness structure; at the same time, there are multiple protrusions 3, which are evenly arranged circumferentially. The protrusions 3 are arranged along the length of the protective sleeve 201, the flame-retardant sleeve 202 or the fixed sleeve 203. The protrusions 3 are in multiple segments, and the length of each segment is less than the length of the protective sleeve 201, the flame-retardant sleeve 202 or the fixed sleeve 203. This can reduce the compression of the protrusions between adjacent protective sleeves 201, flame-retardant sleeves 202 and fixed sleeves 203, ensure the bending effect of the wire harness structure and facilitate use.

[0026] Specifically, in this embodiment, the protective sleeve 201 is a plastic flexible tube. The inner and outer sides of the protective sleeve 201 are provided with protrusions 3, which are connected to the wire harness body 1 and the flame-retardant sleeve 202 through the protrusions 3. The flame-retardant sleeve 202 is made of glass fiber material, and the fixing sleeve 203 is made of elastic plastic material. The inner side of the fixing sleeve 203 is provided with protrusions 3. The protective sleeve 201 and the protrusions 3, as well as the fixing sleeve 203 and the protrusions 3, are all integrally formed. In this embodiment, it is convenient for processing and manufacturing.

A peelable adhesive is provided on the flat part to ensure the fixing effect of the wire harness structure. In this embodiment, the fixing part 203a is located at both ends of the fixing sleeve 203. The angle of the wire harness structure can be adjusted through the fixing part 203a to facilitate wiring.

[0028] Reference Figure 1 and Figure 2 The fixed sleeve 203 is provided with locking buckles 203b at both ends. The locking buckles 203b are sleeved on the outside of the flame-retardant sleeve 202. The locking buckles 203b are provided with multiple elastic pieces. The elastic pieces are inclined and can be inserted between the fixed sleeve 203 and the flame-retardant sleeve 202. The position of the fixed sleeve 203 can be fixed by the elastic pieces, which facilitates connection.

[0029] Reference Figure 2 The main body of the wiring harness 1 includes a control line 101, a power supply line 102, and a grounding line 103. The control line 101 is composed of multiple segments connected end to end to reduce bending of the wiring harness and prevent wire breakage. The connection points of the multiple control lines 101 are provided with connection terminals and heat shrink sleeves are fitted on the connection terminals to protect the connection points and extend their service life.

[0030] The implementation principle is as follows: This application improves the protection effect of the wire harness body 1 by concentrically setting a protective sleeve 201, a flame-retardant sleeve 202, and a fixing sleeve 203 on the outside of the wire harness body 1. At the same time, a protruding strip 3 is set on the protective sleeve 201, the flame-retardant sleeve 202, or the fixing sleeve 203 to separate the protective sleeve 201, the flame-retardant sleeve 202, and the fixing sleeve 203, forming a gap between each sleeve, which facilitates heat dissipation and ventilation, reduces the wire harness temperature, and ensures the stable operation of the wire harness. By setting a fixing part 203a on the outside of the fixing sleeve 203, and setting a tearable adhesive on the fixing part 203a, the wire harness body 1 can be fixed, which is convenient for installation. At the same time, the fixing part 203a is located at both ends of the fixing sleeve 203, which can be bent at a certain angle and fixed, which is convenient for wiring.
