Description

Multi-functional universal charging connection harness Technical Fields

[0001] This utility model relates to the field of charging connection cable technology, and specifically to a multifunctional universal charging connection cable harness. Background Technology:

[0002] Currently, charging and data transfer for many digital electronic devices typically require a charging cable.

[0003] Because PFC (Flexible Printed Circuit) has excellent flexibility and maintains its characteristics of being lightweight, thin, and easy to bend, some data cables now use PFC to connect the plugs at both ends, making the product highly reliable.

[0004] For example, Chinese Utility Model Patent Application No. 202323042257.7 discloses a data cable adapter cable, belonging to the field of adapter cable technology, to solve the problem that when using mobile phones or electronic devices while charging, the flatness of the round wire structure of the connecting cable is poor, making it easy to pinch the hand and affecting user operation. The data cable adapter cable includes: an adapter plug, a connecting component, and a mobile phone plug component; the adapter plug is generally a cuboid structure; one end of the adapter plug is fixedly connected to the connecting component; one end of the mobile phone plug component is connected to the connecting component, and the other end of the mobile phone plug component is connected to the mobile phone; the mobile phone plug component includes: a flexible connecting wire; the flexible connecting wire is generally a flat and long cuboid structure, and one end of the flexible connecting wire is connected to the connecting component. The flexible connecting wire in the data cable adapter cable is a flexible FPC component, which can bend at 90 degrees and swing at 180 degrees, has higher flatness, and is more comfortable to use than the round connecting wire, avoiding pinching the hand.

[0005] However, the aforementioned data cable adapter has some shortcomings: the phone plug in the phone connector assembly is connected to the flexible connector without a shielding structure at the solder joint, which affects signal transmission quality; at the same time, it only exposes the connection between the phone plug and the flexible connector without setting a structure to strengthen the connection between the phone plug and the flexible connector, which poses a risk of detachment due to pulling, affecting product quality.

[0006] In view of the above, the inventors propose the following technical solution. Invention content and utility model content:

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a multifunctional universal charging connection harness.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-functional universal charging connection harness includes a first male connector, a second male connector, and a PFC cable connected between the first male connector and the second male connector and electrically connected to the first male connector and the second male connector, and a flexible outer sheath integrally covering the outer surface of the PFC cable and the ends of the first male connector and the second male connector.

The rear end of the first welding portion is bent upward. The first adapter board has a second vertical section, the upper end of which is bent to form a second welding section located directly above and parallel to the first welding section.

[0014] Furthermore, in the above technical solution, the shielding shell includes an upper shell and a lower shell that are fixed to the outside of the insulating inner mold by wrapping them together. The upper shell and the lower shell are fixed by laser welding.

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] As shown in Figures 1-7, this is a multifunctional universal charging connection harness, which includes a first male connector 1, a second male connector 2, and a PFC cable 3 connected between the first male connector 1 and the second male connector 2 to electrically connect the first male connector 1 and the second male connector 2, and a flexible outer sheath 4 integrally covering the outer surface of the PFC cable 3 and the ends of the first male connector 1 and the second male connector 2. Since PFC (Flexible Printed Circuit) has excellent flexibility and maintains the characteristics of light weight, thin thickness and good bending, this utility model uses the PFC cable 3 to connect the plugs at both ends, so that the product has high reliability, light weight, thin thickness and good bending.

[0028] In this invention, the first male connector 1 is welded and fixed to the end of the PFC cable 3, and an insulating inner mold 5 is integrally formed at the welded area between the first male connector 1 and the PFC cable 3. A shielding shell 6 is also fixedly wrapped around the outside of the insulating inner mold 5, and the flexible outer skin 4 further wraps around the shielding shell 6. This invention adds an insulating inner mold 5 to the welded area between the first male connector 1 and the PFC cable 3, which increases the connection strength between the two, avoids the risk of detachment due to pulling, and ensures a stable electrical connection, thus improving product quality. Furthermore, the shielding shell 6, fixedly wrapped around the outside of the insulating inner mold 5 and further wrapped around the shielding shell 6 by the flexible outer skin 4, further improves the stability of the connection structure. The shielding shell 6 also functions to shield against external signal interference, ensuring uninterrupted signal transmission and improving signal transmission quality. In particular, the shielding shell 6 covering the welded area between the first male connector 1 and the PFC cable 3 gives this invention a strong market competitiveness.

[0029] The specific structure of the first male connector 1 is as follows:

[0030] The first male connector 1 includes a first connector 11 and a first adapter plate 12 that is welded and fixed to the first connector 11. The end of the PFC cable 3 is welded and fixed to the first adapter plate 12. The insulating inner mold 5 is integrally wrapped around the first adapter plate 12 and also wraps the end of the PFC cable 3 and the rear end of the first connector 11. Its structure is stable and effectively prevents the PFC cable 3 from accidentally detaching from the first connector 11.

[0031] The PFC cable 3 has a first bend 31 formed at its end, so that the center of thickness of the PFC cable 3 and the center of thickness of the first adapter plate 12 are on the same horizontal plane. Therefore, after the PFC cable 3 is welded to the first adapter plate 12, the PFC cable 3 and the first adapter plate 12 remain on the same horizontal plane, ensuring that the thickness of the flexible outer skin 4 is uniformly centered and that the solder joints do not fall off.

[0032] The first male connector 1 is perpendicular to the PFC cable 3. The first adapter plate 12 is perpendicular to the PFC cable 3, forming a bent male connector.

[0033] To achieve double welding between the PFC cable 3 and the first adapter plate 12, and to better install it onto the shielding shell 6 without damaging the PFC cable 3, the following design was implemented: the rear end of the first bent portion 31 is bent to form a first straight plate portion 32. The rear end of the first straight plate portion 32 is bent upwards and then downwards to form a second straight plate portion 33 parallel to the first straight plate portion 32. The second straight plate portion 33 is bent downwards along one side to form a first vertical portion 34. The lower end of the first vertical portion 34 is bent upwards to form a third straight plate portion 35 located directly below and parallel to the second straight plate portion 33. One side of the third straight plate portion 35 is folded 180 degrees to form a portion located directly below and parallel to the second straight plate portion 33. The first welding part 36 has a rear end that is bent upward to form a second vertical part 37. The upper end of the second vertical part 37 is bent to form a second welding part 38 located directly above the first welding part 36 and parallel to the first welding part 36. The second welding part 38 and the first welding part 36 are distributed in an overlapping manner with a gap between them. The rear end of the first adapter plate 12 is inserted into the gap from the side of the PFC cable 3. The first solder pad 121 on the upper side of the rear end of the first adapter plate 12 is soldered and fixed to the first solder joint 381 on the lower rear side of the second welding part 38 by a wire or solder and is conductive. The second solder pad 122 on the lower rear end of the first adapter plate 12 contacts and is soldered to the second solder joint 361 on the upper rear side of the first welding part 36 and is conductive.

[0034] The insulating inner mold 5 also integrally wraps the third straight plate portion 35, the first welding portion 36, the second vertical portion 37, and the second welding portion 38, forming a stable connection, making the connection between the first adapter plate 12 and the PFC cable 3 more stable; a gap is formed between the upper end of the insulating inner mold 5 and the lower surface of the second straight plate portion 33, and the shielding shell 6 partially passes through the gap and is placed below the second straight plate portion 33, which will not damage the PFC cable 3, and also facilitates the design of the first male connector 1 and the PFC cable 3 being perpendicular to each other.

[0035] The shielding shell 6 includes an upper shell 61 and a lower shell 62, which are fixed to the outside of the insulating inner mold 5 by wrapping around it from the top and bottom. The upper shell 61 and the lower shell 62 are fixed by laser welding. The upper shell 61 has a first mating part 611 formed by bending outward on both sides, and the lower shell 62 has a second mating part 621 formed by bending outward on both sides. The first mating part 611 and the second mating part 621 are mated and welded together, resulting in an extremely stable assembly structure and a large welding area. The upper shell 61 and the lower shell 62 have the same shape and size and are 180° rotationally symmetrical. That is to say, only one shell needs to be made during the manufacturing process, which can be used as both the upper shell 61 and the lower shell 62, thus reducing manufacturing costs.

[0036] The structure of the second male head 2 is described in detail below:

[0037] The second male connector 2 includes a second connector 21 and a second adapter plate 22 that is welded and fixed to the second connector 21. The other end of the PFC cable 3 is welded and fixed to the second adapter plate 22. The flexible outer sheath 4 covers the entire second adapter plate 22 and the LED indicator 221 and the rear end of the second connector 21 provided on the second adapter plate 22. The connection is stable, and when powered on, the LED indicator 221 will light up and be exposed to the outside through the flexible outer sheath 4 to achieve the function of power-on indication.

[0038] The PFC cable 3 has a second bend 39 formed by bending its end, so that the center of thickness of the PFC cable 3 and the center of thickness of the second adapter plate 22 are on the same horizontal plane. Therefore, after the PFC cable 3 is welded to the second adapter plate 22, the PFC cable 3 and the second adapter plate 22 remain on the same horizontal plane, ensuring that the thickness of the flexible outer skin 4 is uniformly centered and that the solder joints do not fall off.

[0039] The second male connector 2 is perpendicular to the PFC cable 3 and is also a bent structure. The first male connector 1 and the second male connector 2 extend from the same side of the flexible outer sheath 4 and are parallel to each other, which can meet the needs of two electrical appliances that need to be plugged in on the same side, and can save more space. The second adapter plate 22 is perpendicular to the PFC cable 3.

[0040] The flexible outer skin 4 is integrally injection molded from TPU material, which makes the product more flexible. The upper and lower surfaces of the flexible outer skin 4 are formed with positioning holes 41 to prevent the PFC cable 3 from deforming due to molding pressure. The positioning holes 41 can prevent the PFC cable 3 from deforming due to molding pressure of the flexible outer skin 4 and make the molding degree of the flexible outer skin 4 more uniform.

[0041] In summary, this utility model adds an insulating inner mold 5 to enclose the welding area between the first male connector 1 and the PFC cable 3, which increases the connection strength between the two and avoids the risk of separation due to pulling, thus ensuring a stable electrical connection and improving product quality. Furthermore, a shielding shell 6 is also wrapped and fixed outside the insulating inner mold 5, and the flexible outer skin 4 further encloses the shielding shell 6, which further improves the stability of the connection structure. The shielding shell 6 also serves to shield against external signal interference, ensuring that signal transmission is not interfered with and improving signal transmission quality. In particular, the shielding shell 6 covering the welding area between the first male connector 1 and the PFC cable 3 gives this utility model a strong market competitiveness.
