Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically to an ultra-fine coaxial wire harness. Background Technology

[0002] As 5G communication modules, wearable devices, and minimally invasive medical instruments develop towards being "lighter, thinner, shorter, and smaller," the diameter of internal wiring harnesses needs to be reduced from over 1mm to less than 0.5mm, or even 0.2mm, to fit the miniaturized assembly space. Ultra-fine coaxial cable harnesses can be embedded in smaller devices to achieve image signal transmission, while traditional cable harnesses cannot meet the requirements due to their excessive size.

[0003] While existing technologies can reduce size and be embedded in smaller devices, the lack of a protective structure makes it difficult to suppress crosstalk and attenuation of high-frequency signals. Furthermore, the outer sheath can easily rub against and damage the insulation layer of the connecting wires, affecting normal use. The absence of an anti-slip structure also results in a low coefficient of friction between the fingers and the connecting sheath during insertion and removal, making it difficult to grip and apply force, thus impacting normal operation. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an ultra-fine coaxial cable harness, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: an ultra-fine coaxial cable harness, including a connecting wire, a wire sleeve is provided at the outer edge of the connecting wire, and connecting sleeves are provided at both ends of the wire sleeve away from the center line. A circuit board is provided at the end of the connecting wire away from the center line, and a connector assembly is provided at the end of the connecting wire away from the circuit board.

[0006] The connector assembly includes a connecting end, a connecting port, and a groove. The two ends of the connecting end away from the center line are fixedly installed with fixing plates. The end of the fixing plate away from the center line has a positioning groove. The end of the connecting port near the fixing plate is fixedly installed with a positioning plate. The end of the connecting port away from the positioning plate has a slot. The end of the connecting end away from the positioning plate is fixedly installed with a retainer.

[0007] Preferably, the sleeve includes a braided metal tube and a protective fabric, wherein the braided metal tube is a metal braided tube and the protective fabric is acetate cloth.

[0008] Through the above technical solution, the mesh tube adopts metal braiding, which can form an electromagnetic shielding layer, effectively suppressing crosstalk and attenuation of high-frequency signals. The protective cloth, as a buffer layer, can absorb the mechanical stress when the wire harness is bent, and avoid the metal mesh tube from rubbing and damaging the insulation layer of the connecting wire. At the same time, its temperature resistance can be adapted to high and low temperature environments.

[0009] Preferably, a plurality of limiting grooves are provided along the inner edge of the protective fabric, and the limiting grooves have the same length and width as the connecting line.

[0010] The above technical solution uses a limiting groove to position a pair of connecting wires, preventing multiple wire harnesses from shifting in the wire sleeve and causing the connecting wires to rub against each other in the wire sleeve, which would damage the insulation layer. It also separates the wires, thus avoiding easy mutual interference.

[0011] Preferably, the outer edge of the connecting sleeve is provided with anti-slip texture, the cross-section of the anti-slip texture is "spiral", and one end of the connecting sleeve is provided with a through groove, the through groove being adapted to the connecting wire.

[0012] The above technical solution increases the coefficient of friction through the spiral anti-slip texture, making it easier to grip and apply force during manual insertion and removal. Furthermore, the through slot and the connecting wire allow the wire harness to pass through smoothly, and the interference fit can fix the connecting wire, preventing loosening at the connection between the connector assembly and the wire harness.

[0013] Preferably, a placement plate is fixedly installed at one end of the connector assembly near the connecting wire, and the placement plate is in contact with the connecting wire.

[0014] The above technical solution, through the design of the placement board, can guide the installation of the connecting wires before and after installation, thereby preventing the connecting wires from shifting from the installation position of the connector assembly and thus affecting its normal use.

[0015] Preferably, the width of the card slot is the same as the width of the connection port, and a limiting groove is formed at the end of the card sleeve away from the connection end.

[0016] Through the above technical solution, by designing the card slot and the limiting groove, when connected with another set of connectors, one end of the other set of connectors can be inserted into the card slot, and then its elastic element can be inserted into the groove, thereby achieving quick locking between the two.

[0017] Preferably, there are two identical card sleeves and limiting grooves, and the two card sleeves and limiting grooves are symmetrically distributed about the center line of the card slot.

[0018] The above technical solution, through the design of two ferrules and a second limiting groove, can improve the connection stability between the connector assembly and another set of connectors, thereby improving its stability and preventing displacement, which could lead to detachment and affect normal use.

[0019] Compared with the prior art, this utility model provides an ultra-fine coaxial cable harness, which has the following beneficial effects:

[0020] 1.

At the same time, its temperature resistance is suitable for high and low temperature environments.

[0021] 2. This ultra-fine coaxial cable harness increases the coefficient of friction through spiral anti-slip texture, making it easier to grip and apply force during manual insertion and removal. The through slot and the connection wire fit together allow the cable harness to pass through smoothly, and the interference fit can fix the connection wire to prevent loosening at the connection between the connector assembly and the cable harness. The placement plate design can guide the cable before and after installation. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-6 As shown, the present invention provides an ultra-fine coaxial cable harness, including a connecting line 4, a cable sleeve 1 provided at the outer edge of the connecting line 4, a connecting sleeve 2 provided at both ends of the cable sleeve 1 away from the center line, a circuit board 5 provided at one end of the connecting line 4 away from the center line, and a connector assembly 6 provided at one end of the connecting line 4 away from the circuit board 5.

[0031] The connector assembly 6 includes a connecting end 601, a connecting port 604, and a groove 609. The two ends of the connecting end 601 away from the center line are fixedly mounted with fixing plates 602. The fixing plate 602 away from the center line has a positioning groove 603 through it. The connecting port 604 near the fixing plate 602 is fixedly mounted with a positioning plate 605. The connecting port 604 away from the positioning plate 605 has a slot 606. The connecting end 601 away from the positioning plate 605 is fixedly mounted with a retainer 607.

[0032] Specifically, the cable sleeve 1 includes a braided metal tube 101 and a protective cloth 102. The braided metal tube 101 and the protective cloth 102 are made of acetate cloth. The advantages are that the braided metal tube 101 can form an electromagnetic shielding layer, effectively suppressing crosstalk and attenuation of high-frequency signals. The protective cloth 102, as a buffer layer, can absorb the mechanical stress when the cable bundle is bent, and prevent the metal braided metal tube from rubbing and damaging the insulation layer of the connecting wire 4. At the same time, its temperature resistance can be adapted to high and low temperature environments.

[0033] Specifically, multiple limiting grooves 103 are provided along the inner edge of the protective cloth 102. The limiting grooves 103 have the same length and width as the connecting wires 4. The advantage is that the limiting grooves 103 can position the connecting wires 4, preventing multiple wire bundles from shifting in the sleeve 1, which would cause the connecting wires 4 to rub against each other in the sleeve 1 and damage the insulation layer. It can also separate the wires, thus avoiding easy mutual interference.

[0034] Specifically, the outer edge of the connecting sleeve 2 is provided with anti-slip texture 8, the cross-section of which is spiral. One end of the connecting sleeve 2 is provided with a through groove 3, which is adapted to the connecting wire 4. The advantage is that the spiral anti-slip texture 8 increases the coefficient of friction, making it easier to grip and exert force during manual insertion and removal. Furthermore, the fit between the through groove 3 and the connecting wire 4 allows the wire harness to pass through smoothly and also fixes the connecting wire 4 through the interference fit, preventing the connector assembly 6 from loosening at the connection point with the wire harness.

[0035] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, a placement plate 7 is fixedly installed on one end of the connector assembly 6 near the connecting line 4. The placement plate 7 is in contact with the connecting line 4. The advantage is that the design of the placement plate 7 can guide the connecting line 4 before and after installation, thereby preventing the connecting line 4 from shifting from the installation position of the connector assembly 6, which would affect its subsequent normal use.

[0037] Specifically, the width of the slot 606 is the same as the width of the connector 604. The end of the sleeve 607 away from the connector 601 has a limiting groove 608. The advantage is that, through the design of the slot 606 and the limiting groove 608, when connected to another set of connectors, one end of the other set of connectors can be inserted into the slot 606, and then its elastic element can be locked into the groove 609, thereby achieving quick locking between the two.

[0038] Specifically, there are two identical ferrules 607 and limiting grooves 608. The two ferrules 607 and limiting grooves 608 are symmetrically distributed about the center line of the slot 606. The advantage is that the design of two ferrules 607 and limiting grooves 608 can improve the connection stability between the connector assembly 6 and another set of connectors, improve its stability, and avoid displacement, which could lead to detachment and affect normal use.

[0039] Working Principle: During use, the braided metal tube 101 forms an electromagnetic shielding layer, effectively suppressing crosstalk and attenuation of high-frequency signals. The protective cloth 102 acts as a buffer layer, absorbing the mechanical stress during wire bending and preventing the metal tube from rubbing against and damaging the insulation layer of the connecting wire 4. Its temperature resistance also allows it to adapt to high and low temperature environments. The limiting groove 103 positions the connecting wire 4, preventing multiple wires from shifting within the sleeve 1 and causing friction between the connecting wires 4 within the sleeve 1, which could lead to insulation damage. It also separates the wires, preventing easy mutual interference. The spiral anti-slip texture 8 increases the coefficient of friction, facilitating gripping and force application during manual insertion and removal. Furthermore, the fit between the through groove 3 and the connecting wire 4 allows the wires to pass smoothly through while also providing an interference fit. The design of the placement plate 7, through its fixed position, prevents the connector assembly 6 from loosening at the connection point with the wire harness. This guides the connection before and after the installation of the connecting wire 4, preventing misalignment between the connecting wire 4 and the connector assembly 6, which would affect its subsequent normal use. The design of the slot 606 and the limiting slot 608 allows for quick locking when connecting to another connector; one end of the other connector can be inserted into the slot 606, and its elastic element can then engage with the groove 609. The two retaining sleeves 607 and the limiting slot 608 enhance the connection stability between the connector assembly 6 and the other connector, preventing displacement and subsequent detachment that could affect normal use.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
